[0002] An underground sewage lifting pump station is a device that lifts and transports sewage to a sewage treatment plant or other treatment facilities. It is usually buried underground to save ground space and reduce the impact on the surrounding environment. An underground sewage lifting pump station is mainly composed of an inlet pipe, a pump room, an outlet pipe, and a control system. Sewage enters the pump room through the inlet pipe, and the water pump in the pump room lifts and transports the sewage to the outlet pipe, and finally discharges it to a sewage treatment plant or other treatment facilities.

[0031] The filter assembly also includes two debris collection boxes 9, which are fixedly connected to the surface of the inspection platform 5. The upper end of the inspection platform 5 is provided with two connecting channels 10, which are fixedly connected to the corresponding debris collection boxes 9 and filter cartridges 11 respectively.

[0032] A top cover 2 is hinged at the upper end of the sewage lifting pump station 1, a climbing ladder 4 is welded to the top of the inside of the sewage lifting pump station 1, a sludge pump 6 is fixedly connected to the surface of the maintenance platform 5, and a sludge output pipe 7 is fixedly connected to the output end of the sludge pump 6.

[0033] The inner wall of the sewage lifting pump station 1 is fixedly connected to a sewage inlet pipe 3, and a movable plate 15 is arranged at the lower end of the sewage inlet pipe 3. The upper surface of the movable plate 15 is conical, and the upper end of the movable plate 15 is fixedly connected to a connecting rod 16, which is slidably connected to the sewage inlet pipe 3. A spring 17 is sleeved on the surface of the connecting rod 16, and both ends of the spring 17 are fixedly connected to the sewage inlet pipe 3 and the connecting rod 16 respectively. There are three connecting rods 16 and three springs 17, which are respectively arranged in a ring shape at the upper end of the movable plate 15.

[0034] When using the pump station, first bury the sewage lifting pump station 1 in the ground, and pour concrete on the periphery of the sewage lifting pump station 1 to fix it. First, discharge the sewage from the sewage inlet pipe 3 into the interior of the sewage lifting pump station 1. In the process of sewage being discharged into the sewage lifting pump station 1, the sewage will impact the movable plate 15 and make the movable plate 15 move to the lower end.

In the process of sewage being discharged into the sewage lifting pump station 1, the sewage will impact the movable plate 15 and move the movable plate 15 to the lower end. The movable plate 15 drives the connecting rod 16 to move, and the connecting rod 16 compresses the spring 17. As well as the conical shape of the upper end of the movable plate 15, it is convenient for the sewage to flow, and the sewage is preliminarily filtered through the filter cartridge 11 to prevent the sewage flow rate from being too high and causing excessive impact on the filter cartridge 11.

[0040] The drive motor 12 is started to drive the scraper 13 to rotate, and the scraper 13 drives the scraper connecting block 14 to rotate and stir and scrape the sewage, so that the filter cylinder 11 can filter the sewage. After filtering, the sewage is discharged into the bottom of the sewage lifting pump station 1. The scraper connecting block 14 scrapes the debris inside the sewage to facilitate cleaning of the debris, so that the debris is discharged into the interior of the debris collection box 9 through the connecting channel 10 to collect the debris.

[0041] When there is a lot of sewage inside the sewage lifting pump station 1, start the sludge pump 6 to discharge the sewage inside the sewage lifting pump station 1 through the sludge input pipe 8 and the sludge output pipe 7.
