As the water flows from top to bottom, the scraped scum is washed into the cleaning bucket 202. When the cleaning bucket 202 is raised to the top of the collecting tray 1, the staff can clean the scum in the cleaning bucket 202. After the cleaning is completed, the driving motor is used to drive the screw rod 204 to reverse, so that the cleaning bucket 202 is lowered and reset. During the descending process of the cleaning bucket 202, the inner wall of the filter residue bucket 201 is scraped again, so that a small amount of scum attached to the inner wall of the filter residue bucket 201 after the cleaning bucket 202 rises again is scraped off, and the cleaning bucket 202 scrapes the scum to the bottom of the cleaning bucket 202, reducing the scum adhesion on the inner wall of the filter residue bucket 201, so that the scum in the filter residue bucket 201 can be cleaned during the scum cleaning process, thereby improving the scum cleaning efficiency.

[0027] Working principle: During use, the staff uses the airbag 5 and the first counterweight 401 to make the installation position of the collection tray 1 slightly lower than the horizontal plane, so as to facilitate the entry of scum on the sewage surface. When the staff places the device in the water, the length of the connecting rope can be adjusted according to the water depth, so that the second counterweight 602 is anchored at the position of the device at the bottom of the water. The rotation of the winding roller 601 can be limited by the clamping shaft 7. The submersible pump 303 extracts the sewage, and the sewage enters the installation pipe 3 from the collection tray 1 and the conveying pipe 2. The filter hopper 201 and the cleaning bucket 202 in the installation pipe 3 filter the scum. When the filter screen on the inner wall of the filter hopper 201 is blocked by the scum, the staff starts the driving motor to drive the screw 204 to rotate, so that the cleaning bucket 202 rises from the filter hopper 201. During the rising process of the cleaning bucket 202, the cleaning bucket 202 filters the filter hopper 2 01 is scraped off the scum on the inner wall. As the water flows from top to bottom, the scraped scum is washed into the cleaning bucket 202. When the cleaning bucket 202 is raised to the top of the collecting plate 1, the staff can clean the scum in the cleaning bucket 202. After the cleaning is completed, the driving motor is used to drive the screw rod 204 to reverse, so that the cleaning bucket 202 is lowered and reset. During the descent of the cleaning bucket 202, the inner wall of the filter residue bucket 201 is scraped again, so that a small amount of scum attached to the inner wall of the filter residue bucket 201 after the cleaning bucket 202 rises again is scraped off, and the cleaning bucket 202 scrapes the scum to the bottom of the cleaning bucket 202 to reduce the attachment of scum to the inner wall of the filter residue bucket 201. When the screw rod 204 drives the cleaning bucket 202 to rise and fall, the guide rod 4 guides and limits the cleaning bucket 202. At the same time, the first counterweight block 401 cooperates with the driving motor on the top surface of the mounting plate 301 to ensure the overall balance of the device.
