The trash rack frame 1 and the multiple trash rack plates 3 form a trash rack. During use, the trash rack plates 3 intercept impurities in the water flow, and the cleaning frame 25 is disposed on the side of the trash rack plate 3 that intercepts impurities.

[0025] like Figure 2 As shown, the cleaning mechanism 2 also includes a fixed frame 21 fixedly connected to the surface of the trash rack 1. A lead screw 22 is rotatably connected to the inner wall of the fixed frame 21. A motor 23 is fixedly connected to the top of the fixed frame 21. The top of the lead screw 22 passes through the fixed frame 21 and is fixedly connected to the output shaft of the motor 23. A movable plate 24 is threadedly connected to the surface of the lead screw 22. One side of the movable plate 24 passes through the fixed frame 21 and is fixedly connected to the surface of the cleaning frame 25.

[0026] A protective frame is provided at the top of the fixed frame 21, and the motor 23 is located inside the protective frame. In the initial state, the device moves the cleaning frame 25 downward to the lowest height.

[0027] When it is necessary to clean the impurities intercepted by the trash rack 3, the controller starts the motor 23. The output shaft of the motor 23 drives the lead screw 22 to rotate, thereby causing the moving plate 24 to move the cleaning frame 25 upward. At this time, the cleaning frame 25 will scrape and clean the impurities intercepted by the trash rack 3. The cleaned impurities enter the collection frame 27 through the discharge port 26. The lower end of the top of the guide block 29 is horizontal with the inner bottom wall of the cleaning frame 25. During the upward movement of the cleaning frame 25 for cleaning, the guide block 29 will simultaneously intercept the impurities scraped off by the cleaning frame 25 and guide them through the discharge port 26 into the collection frame 27 under the guidance of its inclined surface.

The sealing plate 212 can be installed on the collection frame 27 by bolts to seal the collection frame 27.

[0033] When the cleaning frame 25 drives the collection frame 27 to move upwards, under the action of the plurality of through holes 211 and the water flow pressure during the upward movement, a pressure channel will be formed in the collection frame 27 to cause the impurities in the cleaning frame 25 to always stay in the collection frame 27.

[0034] When the cleaning frame 25 completes the cleaning and drives the collection frame 27 to move to the uppermost position, the sealing plate 212 can be opened by the staff to clean the impurities in the collection frame 27.

[0035] As shown in Figure 2 , the top end and the bottom end of the moving plate 24 are fixedly connected with corrugated sleeves 213, and the other end of the corrugated sleeve 213 is fixedly connected with the inner wall of the fixed frame 21.
