[0034] The functional principle of the utility model can be explained through the following operation modes:

[0035] When the device is used, first, rainwater enters the processing chamber 1 through the circular screen plate 3. On the screen plate, larger debris is intercepted, while smaller water flows through the screen holes on the circular screen plate 3 and flow into the processing chamber 1;

[0036] In the treatment bin 1, the guide structure effectively guides the sewage flowing into the treatment bin 1. Under the guidance of the guide plate 1 13, the partition plate 12 and the guide plate 2 14, the sewage pushes the driving plate 7 to rotate, the driving plate 7 drives the ring 6 to rotate, the ring 6 drives the rotating rod 1 5 to rotate, the rotating rod 1 5 drives the bevel gear 1 8 to rotate, thereby driving the bevel gear 2 9 meshing with the bevel gear 1 8 to rotate, the bevel gear 2 9 drives the rotating rod 2 10 to rotate, the rotating rod 2 10 drives the triangular scraper 11 to rotate and scrape the debris on the screen plate; under the action of the triangular scraper 11, the debris is collected by the collection box 23 after passing through the debris discharge port 22. When the collection box 23 is full of debris, the staff can remove the collection box 23 by tightening the fastening bolts to collect the debris in the collection box 23;

[0037] When the triangular scraper strip 11 and the circular screen plate 3 need to be disassembled for cleaning or replacement, the anti-slip rod 18 and the anti-slip ring 19 are screwed to remove the triangular scraper strip 11 relative to the rotating rod 10; then the fixing screw 16 can be loosened, the connecting ear 15 can be removed from the mounting groove 21, and the circular screen plate 3 can be removed.

[0038] Finally, the scraped and screened water is discharged from the treatment chamber 1 through the outlet pipe 4, completing the rainwater treatment process.
