[0026] By rotating the first rotating rod 4, the U-shaped scraper 5 can then be rotated, so that the U-shaped scraper 5 can scrape off debris such as gravel on the outer surface of the side filter 3 to ensure smooth water flow.

[0027] In order to rotate the second rotating rod 7, Figure 2 As shown, the driving mechanism includes a motor 10, a third rotating rod 11, a first bevel gear 12 and a second bevel gear 13. The motor 10 is fixedly connected to the side wall of the water collecting frame 9. The third rotating rod 11 is rotatably connected to the inner side of the water collecting frame 9. One end of the third rotating rod 11 passes through one side of the water collecting frame 9 and is fixedly connected to the output end of the motor 10.
