Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is based on and claims priority under 35
U.S.C. .sctn. 119 to Korean Patent Application No. 10-2021-0005396,
filed on Jan. 14, 2021, in the Korean Intellectual Property Office,
the disclosure of which is incorporated by reference herein in its
entirety.
BACKGROUND
1. Field
[0002] One or more embodiments relate to a water-level measuring
device using a gear ratio, and more particularly, to a water-level
measuring device using a gear ratio, the water-level measuring
device measuring a water level by using a weight balance between a
plot and a weight pendulum and measuring a water level of a water
pool in a non-power mechanical fashion through a gear ratio between
a first gear connected to the plot and a cable and a second gear
connected to the weight pendulum.
2. Description of the Related Art
[0003] In general industrial sites, a water gauge for measuring a
water surface of various tanks and heaters is used. The water gauge
used in the industrial sites may include a reflex-type water gauge,
a plain glass-water gauge, etc.
[0004] However, these water gauges are problematic as below. The
reflex-type water gauge, the plain glass-water gauge, etc. check a
water surface from the outside by observing the water surface
through transparent glass, and due to contamination of a glass
portion for identifying a water surface or interference with a
steam portion, it may be difficult to identify the water
surface.
[0005] In the case of one or more water pools used in the
industrial sites, it may be difficult to apply the water gauge, and
thus, the water level is measured by using a measuring device, such
as ultrasonic waves, a radar, a laser, etc. The measuring of the
water level by using the measuring device, such as the ultrasonic
waves, the radar, the laser, etc., uses waves reflected by the
ultrasonic waves, the radar, the laser, etc.
[0006] However, the previous water gauge used in the industrial
sites has the following problems. When the water level is measured
by using the waves reflected by the ultrasonic waves, the radar,
the laser, etc., an error may occur in the measurement of the water
level due to diffused reflection generated on a water surface.
[0007] Also, vapors or bubbles are generated in a high-temperature
environment, and in an environment in which the vapors or bubbles
are generated, it may be difficult to use an ultrasonic measuring
device.
[0008] In addition, in the case of a previous water-surface gauge
and a previous water-level gauge, a measuring device is arranged in
a vertically upper area of a region for which a water surface and a
water level are to be measured. However, in the case of a region
exposed to a hazardous environmental condition, due to for example
radioactivity, corrosiveness, and acidity, it may be difficult to
manage and maintain the measuring device.
[0009] Also, the previous water-level gauge uses electricity and
electronic equipment, and thus, may have to be mounted in a
location appropriate for the mounting of the electricity and the
electronic equipment. However, in the case of the region exposed to
the hazardous environmental condition, due to for example
radioactivity, corrosiveness, and acidity, it may be difficult to
mount the water-level gauge.

[0034] One or more embodiments relate to a water-level measuring
device using a gear ratio, and more particularly, to a water-level
measuring device using a gear ratio, the water-level measuring
device measuring a water level by using a weight balance between a
plot and a weight pendulum and measuring a water level of a water
pool in a non-power mechanical fashion through a gear ratio between
a first gear connected to the plot and a cable and a second gear
connected to the weight pendulum. Hereinafter, embodiments will be
described in detail with reference to the accompanying
drawings.
[0035] Referring to FIG. 1, a water-level measuring device using a
gear ratio according to an embodiment may include a water pool 110,
a plot 120, a cable 130, a first gear 140, a second gear 150, and a
weight pendulum 160.
[0036] The water pool 110 may be filed with a liquid. The water
pool 110 may include various tanks and heaters used in industrial
sites and may include various types of water pools which may be
filled with a liquid.
[0037] The plot 120 may receive buoyancy from the liquid of the
water pool 110, by floating over a water surface of the liquid
filled in the water pool 110. The plot 120 may include various
materials which may receive buoyancy from the liquid of the water
pool 110.
[0038] The cable 130 may be connected to the plot 120 and may
extend to the outside of the water pool 110. Referring to FIG. 1,
the cable 130 may be supported by a supporter 131 and may extend to
the outside of the water pool 110. The cable 130 may maintain
tension while being connected to the plot 120, and the plot 120 may
be vertically moved through the cable 130.
[0039] Referring to FIG. 2, the first gear 140 may be connected to
the cable 130. The first gear 140 may rotate via the movement of
the cable 130 and may be connected with the second gear 150.
[0040] The second gear 150 may be connected with the first gear
140. The first gear 140 and the second gear 150 may be connected
with each other through a first connection chain 141. The weight
pendulum 160 may be connected with the second gear 150 and may move
in up and down directions.
[0041] The second gear 150 may rotate via the movement of the
weight pendulum 160, and via the rotation of the second gear 150,
the first gear 140 may rotate. When the first gear 140 rotates, the
cable 130 may move via the first gear 140. The weight pendulum 160
may be directly connected to the second gear 150. However, the
weight pendulum 160 may be connected to the second gear 150 through
other components, such as an auxiliary gear 153.
[0042] The water-level measuring device using the gear ratio
according to an embodiment may measure a water level of the water
pool 110 through the movements of the plot 120, the cable 130, the
first gear 140, the second gear 150, and the weight pendulum
160.
[0043] According to an embodiment, a weight of the plot 120 may be
greater than a weight of the weight pendulum 160, and the weight of
the weight pendulum 160 may be greater than a weight of the cable
130. In addition, the weight of the plot 120 may be greater than a
sum of the weight of the weight pendulum 160 and the weight of the
cable 130.
[0044] Hereinafter, an operating method of the water-level
measuring device using the gear ratio is described in detail,
according to an embodiment.
[0045] When a water-level of the water pool 110 stands still, the
weight of the plot 120, to which buoyancy is applied, and the
weight of the weight pendulum 160 may form a balance. Here, when
the water level of the water pool 110 falls, the buoyancy applied
to the plot 120 may be reduced.
[0046] As described above, the weight of the plot 120 may be
greater than the sum of the weight of the weight pendulum 160 and
the weight of the cable 130, and thus, when the buoyancy applied to
the plot 120 is reduced, the plot 120 may descend due to the weight
of the plot 120.
[0047] When the plot 120 descends, the cable 130 connected with the
plot 120 may be pulled down, and thus, the first gear 140 may
rotate, and via the rotation of the first gear 140, the second gear
150 may rotate.
[0048] The weight pendulum 160 may ascend via the rotation of the
second gear 150. When the plot 120 descends and reaches a
descending water level of the water pool 110, the plot 120 may
receive again the buoyancy from the liquid of the water pool 110.
When the plot 120 receives the buoyancy again, the weight of the
plot 120 and the weight of the weight pendulum 160 may form a
balance, so that the plot 120 may stop descending.
[0049] When the water level of the water pool 110 rises, buoyancy
may be additionally generated in the plot 120, and thus, the
tension of the cable 130 may be loosened. When the tension of the
cable 130 is loosened, the weight of the weight pendulum 160 may
become greater than the weight of the plot 120 to which the
buoyancy is applied.
[0050] When the weight of the weight pendulum 160 increase, the
weight pendulum 160 may descend, and when the weight pendulum 160
descends, the second gear 150 connected with the weight pendulum
160 may rotate.
[0051] When the second gear 150 rotates, the first gear 140 may
also rotate, and via the rotation of the first gear 140, the cable
130 may be wound. When the cable 130 is wound, the tension of the
cable 130 may be maintained, and the plot 120 may ascend. When the
plot 120 ascends and reaches an ascending level of the water pool
110, a portion of the buoyancy applied to the plot 120 may be
eliminated.
[0052] When the portion of the buoyancy applied to the plot 120 is
eliminated, the weight of the plot 120 and the weight of the weight
pendulum 160 may form a balance, and thus, the plot 120 may stop
ascending.
[0053] Based on this method, the locations of the plot 120, the
cable 130, and the weight pendulum 160 may be changed according to
a level of the water surface of the water pool 110. The water-level
measuring device using the gear ratio according to an embodiment
may measure the water level and the water surface of the water pool
110 according to the locations of the cable 130 and the weight
pendulum 160 that are changed according to the water surface of the
water pool 110.
[0054] The cable 130 and the weight pendulum 160 may be connected
with a measuring portion 170 configured to measure the water level
and the water surface of the water pool 110, through a gear, etc.,
and the water level and the water surface of the water pool 110 may
be indicated to the outside through the measuring portion 170.
[0055] Here, movement distances of the cable 130 and the weight
pendulum 160 may be different from each other. The movement
distance of the weight pendulum 160 may be less than the movement
distance of the cable 130, and thus, by adjusting a gear ratio
between the first gear 140 and the second gear 150, the relative
movement distance between the cable 130 and the weight pendulum 160
may be adjusted.
[0056] The gear ratio between the first gear 140 and the second
gear 150 may be changed according to a mounting environment (a
weight of the weight pendulum, a length of the cable, etc.) of the
plot 120, the cable 130, and the weight pendulum 160. Also, types
of the first gear 140 and the second gear 150 may be changed
according to the mounting environment of the plot 120, the cable
130, and the weight pendulum 160.
[0057] Also, a type of the first connection chain 141 configured to
connect the first gear 140 with the second gear 160 may also be
changed according to the mounting environment of the plot 120, the
cable 130, and the weight pendulum 160.
[0058] A previous water-surface and water-level measuring device
may directly measure a water surface and a water level in a
location near to a region to be measured, and thus, in an
environmental condition hazardous due to radioactivity, acidity,
corrosiveness, etc., it may be difficult for an operator to
maintain and manage the measuring device.
[0059] Referring to FIG. 1, the cable 130 according to an
embodiment may extend to the outside of the water pool 110. Because
the cable 130 extends to the outside of the water pool 110, the
water level of the water pool 110 may be measured from other
locations than a region where environment conditions are hazardous
due to, for example, radioactivity, acidity, corrosiveness,
etc.
[0060] The water-level measuring device using the gear ratio
according to an embodiment may further include a water-level
indicator 171. The water-level indicator 171 may be connected with
the first gear 140, and thus, may indicate the water level of the
water pool 110 to the outside according to the rotation of the
first gear 140.
[0061] Referring to FIG. 2, the water-level indicator 171 may be
connected with a third gear 151, and the third gear 151 may be
connected with the first gear 140. The third gear 151 may be
connected with the first gear 140 through a second connection chain
152, and when the first gear 140 rotates, the third gear 151 may
also rotate.
[0062] The water-level indicator 171 may be configured to indicate
the water level of the water pool 110 to the outside, and the water
level of the water pool 110 may be changed due to the rotation of
the third gear 151.
[0063] The first gear 140 may rotate via the cable 130, and
according to a location of the cable 130, a rotation location of
the first gear 140 may also be changed. As described above, the
location of the cable 130 may be changed according to the water
level of the water pool 110, and thus, the rotation location of the
first gear 140 may also be changed according to the water level of
the water pool 110. The water-level indicator 171 may be configured
to indicate the water level by using the rotation location of the
first gear 140 that is changed according to the water level of the
water pool 110.
[0064] Referring to FIG. 3, the water-level indicator 171 may
include a water-level display 171a configured to display the water
level of the water pool 110 to the outside, and the water-level
display 171a may display the water level of the water pool 110 by
using a number. However, the water-level display 171a is not
limited thereto, and the water-level display 171a may display the
water level of the water pool 110 by using various other available
ways and structures which may enable recognition by the
outside.
[0065] The water-level measuring device using the gear ratio
according to an embodiment may further include a water-surface
indicator 172. The water-surface indicator 172 may be connected to
the weight pendulum 160 and may be arranged outside the water pool
110. The water-surface indicator 172 may indicate a level of the
water surface.
[0066] Referring to FIG. 4, the water-surface indicator 172 may be
moved while being synchronized with the weight pendulum 160. As
described above, the location of the weight pendulum 160 may be
changed according to the water level of the water pool 110, and the
water-surface indicator 172 may indicate the water surface of the
water pool 110 to the outside based on the changed location of the
weight pendulum 160.
[0067] According to an embodiment, the water-surface indicator 172
may be arranged on a line that extends in parallel with the water
surface of the water pool 110, and the level of the water surface
of the water pool 110 may be identified in the outside through the
water-surface indicator 172.
[0068] The cable 130 according to an embodiment may extend to the
outside of the water pool 110, and thus, the water level and the
water surface of the water pool 110 may be measured in a location
other than a location where environmental conditions are hazardous
due to, for example, radioactivity, acidity, corrosiveness,
etc.
[0069] The water-level indicator 171 may be mounted at a safe
external wall 10, rather than a location of the hazardous
environmental condition due to radioactivity, acidity,
corrosiveness, etc., and the water-surface indicator 172 may also
be mounted at a safe location to observe the water surface of the
water pool 110.
[0070] According to an embodiment, a gear ratio of the first gear
140, the second gear 150, and the third gear 151 may be changed to
indicate the water level of the water pool 110 by using the
water-level indicator 171. Also, the gear ratio of the first gear
140, the second gear 150, and the third gear 151 may be changed to
indicate the water surface of the water pool 110 by using the
water-surface indicator 172.
[0071] That is, the water-level measuring device using the gear
ratio according to an embodiment may adjust the gear ratio of the
first gear 140, the second gear 150, and the third gear 151 to
indicate the water level and the water surface of the water pool
110 to the outside through the relative locations of the plot 120,
the cable 130, and the weight pendulum 160.
[0072] However, the water-level measuring device using the gear
ratio according to an embodiment is not limited to including the
first gear 140, the second gear 150, and the third gear 151 and may
further include other gears according to necessity.
[0073] According to an embodiment, the support wall 111 which
vertically extends and into which the plot 120 is inserted may be
provided in the water pool 110. The plot 120 may float over the
water surface of the water pool 110 and may move along the water
surface of the water pool 110.
[0074] When the plot 120 moves along with the water surface of the
liquid, the plot 120 may sway in right and left directions due to
waves or bubbles generated on the water surface. The support wall
111 may be configured to prevent the swaying of the plot 120, and
the support wall 111 may be provided to have a slightly greater
width than the plot 120.
[0075] The swaying of the plot 120 in the right and left directions
due to waves or bubbles of the water surface may be minimized by
the support wall 111, and thus, the accuracy of the water-level
measuring device using the gear ratio according to an embodiment
may be improved.
[0076] The weight pendulum 160 may be connected to the second gear
150, and the weight pendulum 160 may be connected to the second
gear 150 through a connector 161 and a bracket 162.
[0077] Referring to FIGS. 2 and 4, the connector 161 may be
connected to the weight pendulum 160 and may slidingly move in up
and down directions. The connector 161 may be configured to
slidingly move in up and down directions according to the up and
down movement of the weight pendulum 160, and the weight pendulum
160 and the second gear 150 may be connected with each other by the
connector 161. The connector 161 may be directly connected with the
second gear 150 or may be connected with the second gear 150
through the auxiliary gear 153.
[0078] The bracket 162 may vertically extend and the connector 161
may be inserted into the bracket 162. The weight pendulum 160 may
move in up and down directions, and when the weight pendulum 160
moves in up and down directions, the weight pendulum 160 may sway
in right and left directions.
[0079] The bracket 162 may be configured to prevent the swaying of
the weight pendulum 160. The bracket 162 may vertically extend and
restrict the right and left movement of the connector 161, so that
the connector 161 may move only in up and down directions and may
not sway in right and left directions.
[0080] The right and left movement of the connector 161 may be
restricted by the bracket 162, and thus, the weight pendulum 160
connected with the connector 161 may be prevented from swaying in
right and left directions.
[0081] The water-level measuring device using the gear ratio
according to an embodiment may indicate the water level and the
water surface of the water pool 110 through the water-level
indicator 171 and the water-surface indicator 172. However, the
water-level measuring device using the gear ratio is not limited to
using the water-level indicator 171 and the water-surface indicator
172. The water-level measuring device using the gear ratio
according to an embodiment may include various measuring
devices.
[0082] Referring to FIGS. 5 and 6, the water-level measuring device
using the gear ratio according to an embodiment may further include
a water-level transmitter 180 configured to transmit a signal for
measuring a water level of the water pool 110 to the outside.
[0083] The water-level transmitter 180 may be configured to
transmit the signal corresponding to the water level of the water
pool 110 to the outside. The water-level transmitter 180 may
transmit the signal to the outside according to a movement of the
weight pendulum 160. The water-level transmitter 180 may include a
space into which the weight pendulum 160 may be inserted and in
which the weight pendulum 160 may move.
[0084] Referring to FIGS. 5 and 6, the water-level transmitter 180
may include a housing 181, an input terminal 182, and an output
terminal 183.
[0085] The housing 181 may include a space into which the weight
pendulum 160 may be inserted and in which the weight pendulum 160
may move. The input terminal 182 and the output terminal 183 may be
connected to the housing 181 and may include an electric wire
coil.
[0086] The input terminal 182 may be connected to the housing 181
and may be configured to supply a voltage. The output terminal 183
may be connected to the housing 181 and may be configured to
generate a voltage according to a movement of the weight pendulum
160, wherein the voltage generated by the output terminal 183 may
be the signal transmitted to the outside.
[0087] As described above, the weight pendulum 160 may move
according to a water level of the water pool 110. When the weight
pendulum 160 moves according to a change in the water level of the
water pool 110, the weight pendulum 160 may move while being
inserted into the housing 181. Here, the weight pendulum 160 may
include a material for generating the voltage in the output
terminal 183 according to the movement of the weight pendulum
160.
[0088] When the input terminal 182 included in the housing 181
supplies a voltage, and the weight pendulum 160 is inserted into
the housing 181 and moves, the output terminal 183 may generate a
voltage.
[0089] The voltage generated by the output terminal 183 may be
changed according to up and down movement of the weight pendulum
160. The voltage changed according to the up and down movement of
the weight pendulum 160 may be transmitted to the outside, and the
water level of the water pool 110 may be identified by detecting
the voltage.
[0090] The water-level transmitter 180 may be configured to
transmit water level information to the outside of the water pool
110. The water level information of the water pool 110 may be
identified outside the water pool 110 through the water-level
transmitter 180.
[0091] Referring to FIG. 6, the input terminal 182 may include a
battery. The input terminal 182 may receive power from the outside
and there may be a risk of blockage of the power supply according
to an external environment.
[0092] However, when the battery is included in the input terminal
182, even when power is lost according to a change in the external
environment, the voltage may be supplied through the input terminal
182. In detail, when the power is lost according to a change in the
external environment, a relay voltage may be lost, and thus, a
switch is changed from an off-state to an on-state, so that power
may be applied from the battery for a predetermined period of time.
Based on this operation, the reliability of the water-level
measuring device using the gear ratio according to an embodiment
may be improved.
[0093] The water-level measuring device using the gear ratio
according to an embodiment may have the following effects.
[0094] The water-level measuring device using the gear ratio
according to an embodiment may measure a water level by using a
weight balance of the plot and the weight pendulum and may measure
a water level of the water pool in a non-power mechanical fashion
by using the gear ratio between the first gear connected with the
plot and the cable and the second gear connected with the weight
pendulum. Thus, the water-level measuring device using the gear
ratio may measure the water level without being affected by an
external environment.
[0095] Also, the water-level measuring device using the gear ratio
according to an embodiment may measure a water surface by making
the cable connected with the plot extend to the outside of the
water pool to be connected with the weight pendulum, and then,
measuring the water surface through the weight pendulum. Thus, the
water surface of the water pool which is not available for
measurement due to an external environment may be measured without
deteriorating the readability of the water gauge.
[0096] In particular, the water-level measuring device using the
gear ratio according to an embodiment may not physically read a
level of the water surface in the water pool. Rather, the
water-level measuring device may recognize the level of the water
surface through the plot, the cable, and the weight pendulum, and
thus, the readability and the accuracy may be improved, compared
with a previous water gauge.
[0097] Also, the water-level measuring device using the gear ratio
according to an embodiment may simultaneously measure the water
surface and the water level by making the cable connected with the
plot extend to the outside of the water pool and connecting the
cable with the weight pendulum.
[0098] Also, the water-level measuring device using the gear ratio
according to an embodiment may make the cable connected with the
plot extend to the outside of the water pool and may mount the
measuring portion outside the water pool, and thus, an exposure of
an operator to an external environment during a maintenance
operation of the measuring portion may be minimized.
[0099] The previous water-surface and water-level measuring device
may directly measure a water surface and a water level in a
location adjacent to a region to be measured, and thus, where
environmental conditions are harmful due to, for example,
radioactivity, acidity, corrosiveness, etc., it may be difficult
for an operator to maintain and manage the measuring portion.
[0100] However, the water-level measuring device using the gear
ratio according to an embodiment may mechanically measure the water
surface and the water level by using the plot, the cable, and the
weight pendulum, and thus, may semi-permanently measure the water
surface and the water level.
[0101] Also, the water-level measuring device using the gear ratio
according to an embodiment may make the cable connected to the plot
extend to the outside of the water pool and connect the cable with
the weight pendulum, and thus, the measuring portion may be mounted
to be apart from the region to be measured. Thus, it may be
possible to mount the measuring portion in a region having an
environmental condition (with respect to radioactivity, acidity,
corrosiveness, etc.) having a good accessibility for an
operator.
[0102] In addition, in the case of a previous measuring device
using an indirect measuring method, such as a measuring device
using ultrasonic waves, laser beams, etc., it may be highly
probable that an error may occur according to a mounting
environment, etc. However, the water-level measuring device using
the gear ratio according to an embodiment may not use electrical
and electronic equipment and may use non-power mechanical
equipment. Thus, a probability of error occurrence may be reduced,
and the reliability of the operation of the measuring device may be
improved.
[0103] According to an embodiment, a water level may be measured by
using a weight balance of the plot and the weight pendulum, and a
water level of the water pool may be measured in a non-power
mechanical fashion by using the gear ratio between the first gear
connected with the plot and the cable and the second gear connected
with the weight pendulum. Thus, the water level may be measured
without being affected by an external environment.
[0104] Also, according to an embodiment, a water surface may be
measured by making the cable connected with the plot extend to the
outside of the water pool to be connected with the weight pendulum,
and then, measuring the water surface through the weight pendulum.
Thus, the water surface of the water pool which is not available
for measurement due to an external environment may be measured
without deteriorating the readability of the water gauge.
[0105] Also, according to an embodiment, a water surface and a
water level may be simultaneously measured by making the cable
connected with the plot extend to the outside of the water pool and
connecting the cable with the weight pendulum. Also, the cable
connected with the plot may extend to the outside of the water
pool, and the measuring portion may be mounted outside the water
pool, and thus, an exposure of an operator to an external
environment during a maintenance operation of the measuring portion
may be minimized.
[0106] Furthermore, according to an embodiment, electrical and
electronic equipment may not be used, and non-power mechanical
equipment may be used. Thus, a probability of the error occurrence
may be reduced, and the reliability of the operation of the
measuring device may be improved.
