When rainwater flows in the drainage pipeline 3, the rainwater washes the guide plate 53, so that the guide plate 53 and the convex cylinder 5 move outwards of the installation cylinder 4, the convex cylinder 5 moves to enable the guide block 48 to move along the guide groove 52, the convex cylinder 5 moves to stretch the reset spring 54, and when the rainwater flows through the guide plate 53, the diameter of the guide plate 53 gradually reduces along the direction close to the second screen plate 51, so that the water flow speed and the water pressure of the guide plate 53 close to the second screen plate 51 are increased, the rainwater flowing out of the guide plate 53 can better drive the fan impeller 82 to rotate, and the fan impeller 82 rotates to scrape sundries on the second screen plate 51, so that the condition that the second screen plate 51 is blocked by sundries is reduced.

When no rainwater flows in the drainage pipeline 3, the return spring 54 recovers deformation and pulls the convex cylinder 5 to move into the installation cylinder 4, when the return spring 54 completely recovers deformation, the convex cylinder 5 is positioned in the installation cylinder 4, and an operator can take out the installation cylinder 4 through a tool or a lifting device at the moment to clean sundries in the collection box 6, the installation cylinder 4 and the convex cylinder 5.

The implementation principle of the municipal drainage pipeline in the embodiment of the application is as follows: when raining, rainwater flows into the installation cylinder 4 along the sewer pipe 2, the first sieve plate 41 filters sundries with larger particle sizes in the rainwater, the filtered rainwater flows into the convex cylinder 5 and the drainage pipe 3, and the second sieve plate 51 filters the filtered rainwater again; as the debris accumulates on the first screen panel 41, the first screen panel 41 moves downward, and when debris on the first screen panel 41 accumulates to a certain extent, the first screen panel 41 rotates downward while the first screen panel 41 triggers the proximity switch 78, and the driving motor 73 operates to move the scraper 71 to scrape off debris on the first screen panel 41, and the scraped debris falls into the collection box 6 along the first screen panel 41.

The rainwater flows in the convex cylinder 5 so as to push the convex cylinder 5 to move outwards of the installation cylinder 4, the condition that the drainage pipeline 3 is blocked due to the intensive structure in the installation cylinder 4 is reduced, the rainwater flows in the convex cylinder 5 to drive the fan impeller 82 to rotate, and sundries on the second screen plate 51 are scraped while the fan impeller 82 rotates; when no rainwater flows in the drainage pipeline 3, the convex cylinder 5 is positioned in the installation cylinder 4, and an operator can take out the installation cylinder 4 to clean sundries in the installation cylinder 4 and the convex cylinder 5.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
