The supporting mechanism 9 includes a sealing seat 91 fixed to the bottom of the output shaft of the second motor 8, a fixing plate 92 is fixed inside the sealing seat 91, and a slide plate 93 is slidably connected to both sides of the sealing seat 91. A hydraulic damper 94 and a spring 95 are installed between the slide plate 93 and the fixing plate 92. A movable rod 96 is fixed to the side of the slide plate 93, and the movable rod 96 passes through the sealing seat 91 and is connected to a mounting plate 97. A fixing column 98 is fixed to the bottom of the sealing seat 91, and the spring 95 is sleeved on the hydraulic damper 94. The first scraper 10 is fixed to the bottom of the fixing column 98, and the second scraper 11 is fixed to the side of the mounting plate 97.

[0021] In the supporting mechanism 9, the spring 95 drives the slide plate 93 to slide in the fixing seat 91. The slide plate 93 drives the mounting plate 97 and the second scraper 11 through the movable rod 96, so that the second scraper 11 is close to the inner wall of the sedimentation tank 2. The spring 95 is set so that the second scraper 11 is close to the inner wall of the sedimentation tank 2. The hydraulic damper 94 enables the slide plate 93 to reset quickly during the sliding process, thereby ensuring the stability of the second scraper 11 and the inner wall of the sedimentation tank 2.

The sleeve 54 drives the movable plate 6 to slide downward on the inner wall of the sedimentation tank through the threaded transmission with the threaded column 56. The movable plate 6 drives the first scraper 10 and the second scraper 11 through the waterproof shell 7, the second motor 8 and the supporting mechanism 9 to adjust the positions of the first scraper 10 and the second scraper 11. In this process, the output shaft of the second motor 8 drives the first scraper 10 and the second scraper 11 to rotate through the supporting mechanism 9, and the second scraper 11 is used to scrape the mud from the inner wall of the sedimentation tank 2. When the first scraper 10 drops to the bottom of the sedimentation tank 2, the first motor 52 is stopped to make the first scraper 10 clean the bottom of the sedimentation tank 2. In this process, the cleaned sludge is discharged from the drainage pipe 3 together with the clean water.
