Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1-4, the drainage structure of this embodiment includes a sump 1, the outer wall of the sump 1 is equipped with a water inlet pipe 2 in the middle and a sewage pipe 3 in the lower position, and a switch is installed on the sewage pipe 3 The valve 4 and the inner cavity of the sump 1 are fixed with a filter 5. There is a gap between the filter 5 and the inner wall of the sump 1. The sewage enters through the water inlet pipe 2 and is filtered by the filter 5. The filtered debris stays in the filter. 5 and the gap between the sump 1. A scraper 6 is arranged between the filter screen 5 and the inner wall of the sump 1, and a top cover 7 is arranged on the upper part of the sump 1. A motor 8 is fixedly installed on the top cover 7, and a fixed sleeve 9 is fixedly installed at one end of the output shaft at the bottom of the motor 8. , the position of the outer wall of the fixed sleeve 9 is fixedly installed with a connecting rod 10, the top of the scraper 6 is fixedly connected with the connecting rod 10, and the motor 8 drives the scraper 6 through the connecting rod 10 to clean the gap between the filter screen 5 and the sump 1 , the cleaned debris is discharged through the blowdown pipe 3. A drainage pipe 11 is installed at the bottom of the sump 1 . The drain pipe 11 is used to discharge the water filtered through the filter screen 5 .

Further, a plurality of spokes 12 are fixedly arranged on the side of the scraper 6 close to the filter net 5 . The spokes 12 can improve the cleaning effect of the scraper 6 on the filter screen 5 .
