The clean water flows upward from the inlet pipe 7 and then flows out of the outlet pipe 8. Under the action of the flow stabilizer 13, it is evenly sprinkled on the water surface. At the same time, the motor 12 is started, and the driven gear ring 10 on the transmission bracket 5 is rotated through the drive gear 11. This causes the triangular frame 17, which is hinged below the transmission bracket 5, to rotate around the center, further driving the scraper 20 to scrape off the sludge. Due to the inclined setting of the scraper 20, the sludge is gradually driven to fall into the sludge collection cylinder, and then discharged out of the pool through the sewage pipe 9. After the sewage discharge is completed, the steel cable 16 can be driven by the pulley 14 to fold and retract the triangular frame 17. Then, the worn scraper 20 can be replaced through the mounting plate 19 to ensure cleaning capacity.
