[0027] In the embodiment, the pump station water inlet pipe is arranged at the right middle part of the pump station cylinder, the external water enters the pump station cylinder from the pump station water inlet pipe, the water outlet of the pump station water outlet pipe is arranged above the pump station water inlet pipe, the water outlet is connected with the urban sewage network, and the sewage pump is used for pumping the water in the pump station cylinder into the sewage network.

[0028] In the embodiment, the controller, the sewage pump and the driving part are electrically connected, and are used for controlling the operation of the controller.

[0029] Referring to Figure 1 , 2As shown, the driving part includes a screw rod 8, a power component 9 and a positioning part 10, the bottom of the screw rod 8 is rotationally connected with the top of the valve 6, the positioning part 10 is fixedly arranged on the inner wall of the pump station cylinder 1 above the valve 6, the middle part of the screw rod 8 is vertically slidably connected with the positioning part 10, a nut 11 is rotationally installed on the top of the positioning part 10, the middle part of the screw rod 8 is screwed with the nut 11, the power component 9 is installed on the inner wall of the pump station cylinder 1 above the positioning part 10, the power component 9 is configured to drive the nut 11 to rotate and drive the screw rod 8 to vertically move.

[0030] The power component 9 includes a motor 12 and a speed reducer 13, a first gear 14 is arranged on the output shaft of the speed reducer 13, a second gear 15 is arranged on the outer surface of the nut 11, the first gear 14 is engaged with the second gear 15, and the motor 12 drives the first gear 14 to rotate through the speed reducer 13.

[0031] The positioning part 10 includes a fixed block 16 and a sleeve 17, the sleeve 17 is connected with the inner wall of the pump station cylinder 1 through the fixed block 16, the middle part of the screw rod 8 is movably connected with the sleeve 17, and the nut 11 is rotationally installed on the top of the sleeve 17.

[0032] In this embodiment, a sealing protective sleeve (not shown in the figure) is arranged outside the motor and the speed reducer to prevent water from entering and to prevent the motor and the speed reducer from being corroded by water vapor. In this embodiment, two liquid level sensors are arranged, one of which is arranged near the bottom of the pump station cylinder, and the other of which is arranged near the lower part of the water inlet pipe of the pump station. Both of the liquid level sensors are below the power component, so under normal circumstances, the power component will not be submerged in water. When the valve operates, the motor drives the first gear to rotate through the speed reducer. Since the first gear and the second gear are engaged, the nut will rotate. Since the nut is screwed with the screw rod, and the vertical position of the nut will not move, when the nut rotates, the screw rod will be pulled to vertically move. When the screw rod vertically moves, the valve will be simultaneously lifted or lowered, thereby opening or closing the drain pipe.

[0033] Referring to Figure 1 , 2 As shown, the inner end of the drain pipe 5 is provided with a limiting frame 18, and the valve 6 is movably arranged in the limiting frame 18. Vertical sliding grooves are arranged on both sides of the limiting frame, and the two sides of the valve are slidably connected with the vertical sliding grooves of the limiting frame, so as to ensure that the valve can stably open or close the drain. After the valve is lowered to close the drain pipe, the valve can be supported by the limiting frame.

[0034] Referring to Figure 1 , 3As shown, the inner end of the pump station outlet pipe 3 is arranged above the inside of the pump station cylinder 1, and the outer end of the pump station outlet pipe 3 passes through the pump station cylinder 1 and is arranged outside the pump station cylinder 1;

[0036] In this embodiment, the pump station water inlet pipe is arranged in the middle of the right side of the pump station cylinder, and the drain pipe is arranged in the middle of the left side of the pump station cylinder, and the bottom plane of the drain pipe is arranged parallel to and below the bottom of the pump station water inlet pipe. In this way, when the drain pipe is opened, because the bottom plane of the drain pipe is lower than the bottom plane of the pump station water inlet pipe, water can be discharged from the drain pipe after the drain pump is turned on. By setting up multiple sewage pumps, the corresponding number of sewage pumps can be selected to be opened according to the water inflow speed of the pump station water inlet pipe to prevent the water level in the pump station cylinder from being too high. At the same time, a first valve is also set on the branch pipe. When the water level in the sewage network is relatively high, the first valve can be used to close the branch pipe to prevent water in the sewage network from flowing back into the pump station cylinder.

[0037] See also Figure 1 、 3 As shown, a crushing grid 21 is further provided in the pump station cylinder 1 , and the crushing grid 21 is arranged at the water inlet of the pump station water inlet pipe 2 .

[0038] The setting of the crushing grid can crush the large-sized dirt in the sewage entering the water inlet pipe of the pump station, so that it enters the pump station cylinder and is smoothly pumped out by the sewage pump.

[0039] The water inlet pipe of the pump station is arranged below the right side of the water outlet pipe of the pump station.

[0040] The pump station cylinder has an inspection port 22 at the top, and a ladder 23 on the inner wall of the cylinder.
