DETAILED DESCRIPTION OF THE INVENTION
[0021] The following is clearly and completely describes of the
technical solutions in the embodiments of the present invention.
Apparently, the described embodiments are merely some but not all
embodiments of the present invention. All other embodiments
obtained by a person who is skilled in the art based on the
embodiments of the present invention without creative efforts shall
fall within the protection scope of the present invention.
[0022] Referring to FIGS. 1-5, embodiments of the present invention
are set out as the following:
[0023] A vertical-shaft sewage pump with anti-collision switch
includes a water pump driving component 1, a switch control
component 2, a base 3 and a post 4 fixed on the base 3, the water
pump driving assembly 1 includes a driving motor 11 and a casing 12
sleeved on the outside of the driving motor 11, an upper end cover
13 and a lower end cover 14 which respectively fixed at the upper
end and the lower ends of the casing 12. A plurality of cylindrical
bosses 5 is disposed on the lower surface of the lower end cover
14. The cylindrical bosses 5 are provided with internal threads.
Screws 20 are provided at the corresponding positions of the upper
surface of the switch box 21, and the switch control assembly 2 is
installed to the lower side of the water pump drive assembly 1 via
the screws 20 engaged with the internal threads provided on the
cylindrical bosses 5. The switch control assembly 2 also includes a
micro switch 22 housed inside the switch box 21, a guide rod 23 and
a floating ball 24 which is movable up and down along the guide rod
23. A magnetic portion is provided at an end of the guide rod 23
that protrudes into one end of the switch box 21. The upper and
lower sides of the floating ball on the guide rod 23 are
respectively provided with an upper position limitation ring 25 and
a lower position limitation ring 26. An electrical connection part
6 is disposed between the water pump drive assembly 1 and the
switch controlling component 2. The electrical connection part 6
includes a tab 61 which electrically connected with the drive motor
11, a base 62 disposed on the upper surface of the switch box 21
and a pin 63 inserting in the base 62, the upper end of the pin 63
is connected with the tap 61, and the lower end is connected with
the micro switch 22 in the water pump driving assembly via a
wire.
[0024] Further, a convex plate 7 is outwardly extended from the
upper surface of the upper end cover 13, a circular hole is
provided on the convex plate 7, and the circular hole is penetrated
with a hand ring 8. The handle ring 8 is not limited to a circle
shape, a triangle shaped ring, or a square shaped ring, which is
convenient for putting on and taking off during transportation and
carrying are also applicable.
[0025] Further, the bracket assembly 9 includes a front bracket 91
and a rear bracket 92. The front bracket 91 and the rear bracket 92
are connected by screws at one ends, and the other ends of them are
pivotally connected via a round pin extended in a through hole. To
gain an anti-slip effort, the inner surface of the front bracket 91
and the rear bracket 92 is vertically provided with non-slip
guiding grooves 93. A ring-shaped fixation ring 94 disposed on the
end of the rear bracket 92 which is distant from the pillar 4. And
the guide rod 23 is inserted into the fixation ring 94 and plays a
fixation and supporting role therein.
[0026] During operation, when the water level rises and the float
ball moves upwards, when the water reaches the upper water level,
the float ball touches the upper limitation position circle and
brings the guide rod to move upwards. The micro switch in the
switch box is triggered to drive the motor to rotate and the water
pump starts to work. When the water drops, the float ball moves
downwards. When the water reaches the lower water level, the float
ball touches the lower limitation circle and brings the guide rod
to move upwards. The micro switch resets, the motor stops rotating,
and the water pump stops working.

anti-collision switch of the present invention has a simple
mechanism structure and it is easy to operate. The switch part and
the pump body are integrally packaged, and the switch and the motor
are connected in the form of pin-inserting, and the assembly
structure is simplified. The integral structure is not easy to
damage during transportation and has a wide application
prospect.
