Drainage device for sponge city

Abstract

The invention discloses a drainage device for a sponge city. The drainage device includes a drainage pipeline, the upper part of the drainage pipeline is provided with a cover plate, a plurality of leak holes which are in communication with the pipeline are arranged on the cover plate; and a filter plate is fixedly arranged in the drainage pipeline, a rotating shaft is rotatably connected to the filter plate, the rotating shaft arranged on the filter plate is connected with a pressing plate, the side, near the filter plate, of the pressing plate is provided with a plurality of cutting pieces, and the cutting pieces are in contact with the upper surface of the filter plate. When leaves enter the drainage pipeline and block the filter plate, on a rainy day, rain water passes through a water delivery pipe from a groove and hits waterlogging blocks, rain water impact force can drive the rotating shaft to rotate, and further drive the pressing plate to rotate, the cutting pieces fixed to the lower surface of the pressing plate cut up leaves on the filter plate, chopped leaves are driven to the edge of the filter plate by the rotating pressing plate, and blocking the filter plate to some extent is avoided in the case of fewer dreg accumulation.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to a drainage device for a sponge city. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". Like a sponge, a city has good "elasticity" in terms of adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water and uses it when needed. Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwate...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing drainage pipes generally have a cover plate on the top. However, when the design of the cover plate leak hole is small, the leaves are easy to block the leak hole, requiring personnel to clean it regularly, which is time-consuming and laborious. When the design of the cover plate leak hole is large, it cannot stop the volume. Larger waste enters the drain, causing a decrease in the quality of the stored water
