[0002] Sewage pumping station is an engineering facility used to pump and transport sewage in urban drainage projects. When sewage in the sewage pipe cannot be transported or discharged by gravity, or when the pipe is buried too deep, making construction difficult, or when it is at the end of the main pipe and needs to be pumped before entering the sewage treatment plant, a sewage pumping station must be set up. The construction period of the pumping station is extremely short and the installation is extremely simple. Compared with the traditional concrete pumping station, the advantages are more prominent. It has become a trend in the construction of small and medium-sized pumping stations in the future, and it is bound to play a prominent role in the construction of urban drainage and municipal rainwater pumping stations. The sewage pumping station includes components such as tanks, water pumps and control cabinets.

The connecting rod 11 can drive the gear 6 to rotate, and can drive the rotating plate 3 to rotate inside the tank body 1 and change the angle. A motor 13 is arranged on one side of the support frame 12. The output end of the motor 13 is connected to one end of a rotating plate 3. The motor 13 can drive the rotating plate 3 to rotate, and the gear 6 can drive the connecting rod 11 to move, so that the five rotating plates 3 can rotate at the same angle at the same time. It should be noted that inclined surfaces are arranged on both sides of the rotating plate 3, which can assist the rotating plate 3. After the rotation, the adjacent rotating plates 3 can be connected together horizontally end to end.

[0031] See also Figure 3 , Figure 4 and Figure 5 A filter plate 5 is arranged inside the rotating plate 3, and a connecting groove 4 is also opened inside the rotating plate 3. The end of the connecting groove 4 is arranged on one side of the filter plate 5, and a connecting block 7 is arranged on one side outside the tank body 1.
