A rainwater drainage device for sponge city

Abstract

The invention discloses a rainwater drainage device for a sponge city, which comprises a curb, a water inlet is opened in the curb, and a plurality of baffles are connected to the water inlet, and a liquid inlet hole is opened in the baffle, so The water inlet is connected with the road to open a cavity, the side wall of the cavity is penetrated with a sewage pipe, the cavity is sealed and slidably connected with a filter screen, and the cavity on the side of the filter screen away from the sewage pipe is set as The impurity chamber, the top of the impurity chamber is penetrated with an impurity removal port, and the impurity removal port is sealed and rotatably connected with a rotating plate. The advantages are: through the charging and shortening effect of the spring and the connection of the solar battery, it is in the closed state during normal use to avoid objects falling, and when the rain is heavy, the baffle opens the water inlet to improve the drainage effect. And in the reciprocating motion of the filter net, the dirt blocking effect is improved and self-cleaning is realized.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a rainwater drainage device for sponge cities. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, and has good elasticity in adapting to environmental changes and dealing with natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, purifies water when it rains, and releases and utilizes the stored water when needed, so as to realize the free migration of rainwater in the city and from the ecosystem. Starting from services, constructing water ecological infrastructure across scales and combining various types of specific technologies to build water ecological infrastructure is the core of the sponge city. [0003] The core of the...
