When cleaning impurities, the first baffle plate 13 and the second baffle plate 14 are driven to slide by rotating the two transmission screws 15, thereby closing the water guide pipe 5 and exposing the cleaning pipe 9. Then the driving motor 6 drives the transmission shaft 7 and the cleaning scraper 8 to rotate to clean the lower water storage tank 2, and the transmission shaft 7 drives the first gear 10 to rotate, so that the first gear 10 drives the second gear 11 and the dredging shaft 12 to rotate, so that the blades on the surface of the dredging shaft 12 drive the impurities to be discharged, thereby increasing the overall practicality.
