[0002] The integrated pump station is a new generation of pump station that can be used to lift various types of water bodies such as sewage, rainwater, drinking water, river water, etc. It is centrally designed, manufactured, and assembled in the factory, and then transported to the site for rapid turnkey commissioning. It has many advantages such as small size, high efficiency, intelligence, and easy installation. It is widely used in the field of water environment.

[0003] However, when the integrated pump station is used in environmental water bodies such as rivers, it is easy for a large number of fallen leaves to enter the water. After the fallen leaves enter the basket grille of the integrated pump station, they will not be discharged in a short time and will continue to accumulate in the basket grille. If the submersible pump of the integrated pump station needs to work, under the influence of the larger water pump suction force, these fallen leaves will cover the surroundings of the basket grille frame, blocking the grille holes, thereby affecting the normal operation of the submersible pump, and even causing the submersible pump to start and stop frequently and malfunction. In addition, when the integrated pump station is used for sewage lifting, it is easy for a large number of fibrous substances to enter the water, which will also cause similar problems.

The water inlet pipe is arranged at the front end of the grille body to connect the grille body with the water source. The grille body is provided with a hole-shaped structure to intercept impurities such as fallen leaves, fibers, and foreign matter in the incoming water. The cleaning rake moves up and down within a certain range of travel on the inner wall of the grille body, and then continuously scrapes the grille holes to prevent them from being seriously blocked. The hydraulic power device is connected to the hydraulic rod of the cleaning device to provide it with hydraulic oil.

[0007] Furthermore, the top of the hydraulic rod is 30-60 cm higher than the highest operating liquid level of the integrated pump station.

[0008] Furthermore, the pore structure of the grille body is a square grid with a pore diameter of 5-30 mm.

[0019] To facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings.

[0020] Example: See Figure 1A basket grille for preventing clogging by fallen leaves comprises a water inlet pipe 1, a grille body 2, a cleaning device 3 and a hydraulic power device 4. The water inlet pipe 1 is arranged at the front end of the grille body 2, and is used to connect the grille body 2 with the lifting water source. The grille body 2 is a square hole structure, which is used to intercept impurities such as fallen leaves, fibers, foreign matter, etc. in the incoming water, and is manually cleaned regularly through guide rails and chains. The cleaning device 3 consists of a cleaning rake 3.1 and a hydraulic rod 3.2. The cleaning rake 3.1 is arranged closely along the inner wall of the grille body 2 frame, and can move up and down within a certain range of travel, thereby continuously scraping the grille holes to prevent them from being seriously blocked. See Figure 2 The hydraulic rod 3.2 is a sleeve structure, which is arranged in the middle of the cleaning rake 3.1. The lifting and lowering control of the sleeve provides power for the cleaning device 3 to move up and down. The hydraulic power device 4 is connected to the hydraulic rod 3.2 of the cleaning device 3 to provide hydraulic oil for it. The sleeve structure of the hydraulic rod 3.2 includes an inner sleeve 3.21 and an outer sleeve 3.22. The outer sleeve 3.22 can move up and down along the inner sleeve 3.21. The cleaning rake 3.1 includes two, which are respectively arranged at the top and bottom of the outer sleeve 3.22. The stroke of the outer sleeve 3.22 is about half the height of the grille body 2.

[0021] The grid aperture of the grid body 2 is 10 mm.

[0022] The outer shell of the cleaning device 3 is made of SS316. The travel range of the cleaning device 3 covers the full height of the grille body 2 frame.

[0023] See also Figure 3 The cleaning rake 3.1 includes a frame 3.1.1 and rubber strips 3.1.2. The rubber strips 3.1.2 are made of silicone material and are spread all over the outer surface of the frame 3.1.1 and extend outward in a radial shape. A V-shaped diagonal brace is arranged inside the cleaning rake 3.1, and the structure is more stable.

[0024] The top of the hydraulic rod 3.2 is 50 cm higher than the maximum operating liquid level of the integrated pump station.

[0025] See also Figure 1 , Figure 4The utility model is used for an integrated pump station for circulation in urban rivers with a large number of influent fallen leaves. The integrated pump station is equipped with an automated control system to monitor the flow of the submersible pump in real time. When there is a significant drop, the integrated pump station automatically starts the cleaning device 3 and the hydraulic power device 4, and provides real-time feedback on whether the flow of the submersible pump has returned to normal. The hydraulic power device 4 is responsible for providing power, and the cleaning device 3 moves up and down through the hydraulic rod 3.2, and the cleaning rake rubber strip 3.1.2 continuously scrapes the grille holes of the grille body 2. If the flow of the submersible pump returns to normal, the integrated pump station automatically turns off the cleaning device 3 and the hydraulic power device 4 until the next problem occurs. If the flow of the submersible pump cannot return to normal, other problems need to be checked. In the case of a particularly large number of influent fallen leaves or fibrous materials, the integrated pump station can also choose to continuously run the cleaning device 3 to ensure the normal operation of the system. When necessary, manually clean the debris accumulated in the basket grille.
