Description

Technical Field

[0001] The invention relates to the technical field of sewer drainage, in particular to a sewer drainage device suitable for garden construction. Background Art

[0002] Gardening is the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, transforming the terrain, planting trees and flowers, constructing buildings, and arranging garden paths. A sewer is a kind of urban public facility, which refers to the pipes for buildings to discharge sewage and rainwater; it also refers to the underground passages for cities, factories or villages to remove sewage and rainwater.

[0003] The existing Chinese patent document CN221760872U discloses a new type of sewer drainage device suitable for garden construction. Through the design of the filter screen, it can achieve a good filtering effect on tiny dead branches and leaves. When the driving motor is running, the rotating shaft will drive the rotating rod to rotate, and then the rotating rod will drive the extrusion shaft to rotate. At this time, the outer surface of the extrusion shaft will squeeze and push the inside of the push block during rotation, and then the push block will drive the push plate to move under the extrusion and push of the extrusion shaft. Due to the design of the limit groove, the push plate will move to the right under the limit of the limit groove. At this time, one end of the right side of the push plate will push the tiny dead branches and leaves located on the top of the filter screen to move to the right. Then these tiny dead branches and leaves will be discharged from the inside of the filter box through the discharge chute, and finally fall into the inside of the collection box to complete the collection, thereby realizing the function of automatically cleaning the dead branches and leaves on the top of the filter screen, and achieving the effect of preventing the sewer from being blocked after long-term use.

[0004] However, the above-mentioned device is unable to process the fallen leaves and impurities accumulated on the cover plate in the sewer water inlet and the drainage channel. As a result, when a large amount of fallen leaves are accumulated, the water flow cannot completely pass through the cover plate into the drainage channel, and then spreads on the road, causing rainwater to flow freely on the city road, affecting traffic.
