A motor is fixed at the bottom end of the maintenance platform. The output shaft of the motor is connected with a vertical rod through a coupling. A first scraper is fixed at the bottom end of the vertical rod. Two second scrapers are fixed at the top end of the first scraper. An annular shell is arranged below the maintenance platform. The shell is connected with the cylinder body. A plurality of inclined spray nozzles are fixed at the bottom end and the inner side of the shell. A water pump is fixed at the top end of the maintenance platform. A conduit is fixed on the water inlet pipe of the water pump. The bottom end of the conduit is fixed with a metal telescopic pipe. A connecting pipe is fixed on the drain pipe of the water pump. A first valve and a second valve are fixed on the connecting pipe. One end of the first valve away from the connecting pipe is threadedly connected with a hose. A filter screen is arranged inside the hose. One end of the hose away from the first valve is connected with the shell. One end of the second valve away from the connecting pipe is fixed with an elbow pipe. One end of the elbow pipe away from the second valve is connected with the outlet.

[0005] By adopting the above technical solution, a part of water for cleaning needs to be retained inside the cylinder body. Open the first valve, close the second valve, start the water pump and the motor. The water pump pumps the water inside the cylinder body. The water enters the shell through the hose and is sprayed out from a plurality of spray nozzles, which is beneficial to the preliminary flushing of the vertical inner wall of the cylinder body. The output shaft of the motor drives the vertical rod to rotate, and the first scraper and the second scrapers rotate accordingly. The first scraper can clean the dirt on the bottom wall inside the cylinder body, and the second scrapers can clean the dirt on the vertical inner wall of the cylinder body, thereby realizing automatic cleaning. After cleaning, close the first valve and open the second valve. The sewage inside the cylinder body enters the outlet through the elbow pipe and is discharged through the outlet.

[0006] Specifically, two cross bars are fixed on each of the two second scrapers, and the four cross bars are all connected with the vertical rod.

[0007] By adopting the above technical solution, the setting of the cross bar can improve the stability of the second scraper.

[0008] Specifically, a protective cover is rotatably connected to the top end of the inspection opening.

[0009] By adopting the above technical solution, the setting of the protective cover can prevent sundries from falling into the cylinder body.

[0010] Specifically, a protective cover is fixed to the top end of the air vent pipe.

[0011] By adopting the above technical solution, the setting of the protective cover can prevent sundries from falling into the air vent pipe.

[0012] Specifically, a base is fixed to the bottom end of the cylinder body, and a plurality of reinforcing blocks are fixed to the top end of the base. The side walls of the plurality of reinforcing blocks close to the cylinder body are all connected to the cylinder body.

[0013] By adopting the above technical solution, the base can support the cylinder body and improve the stability of the cylinder body.

[0014] Advantages of the present utility model:

[0015] (1) For a self-flushing pump station of the present utility model, a part of water for cleaning needs to be reserved inside the cylinder body.
