Sponge city large and small rainwater diversion and discharge device

Abstract

The invention discloses a sponge city large and small rainwater diversion and discharge device. The device comprises a box body, wherein a placement groove is formed in the top of the box body in a penetrating mode, a top cover is connected to the inner side wall of the placement groove in a sealed and sliding mode, a through hole is formed in the top of the top cover in a penetrating mode, a water outlet is formed in the bottom of the box body, a connecting box is fixedly connected to the bottom of the box body, a mud guard is fixedly connected to the bottom of the connecting box in a penetrating mode, a sliding groove is formed in the inner side wall of the connecting box, and a filter screen is fixedly connected to the inner side wall of the box body. When rainwater in the external environment is small, the rainwater enters the box body through the through hole, then enters the connecting box through the water outlet and is discharged to the underground through the through hole and the mud guard under the diversion effect of a sealing plate, underground water is supplemented, the situation that the life health and safety of citizens are affected due to ground settlement caused by lack of the underground water is prevented, and people are protected to a certain extent.

Description

technical field [0001] The invention relates to the technical field of rainwater drainage for sponge cities, in particular to a rainwater distribution and drainage device for large and small 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 responding to 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, and 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 infrastruct...

AI Technical Summary

Problems solved by technology

[0003] The traditional large and small rainwater diversion devices cannot effectively clean up the impurities in the rainwater, which will cause the impurities to block the drainage pipes, resulting in the accumulation of rainwater in the city, and the traditional devices cannot prevent Due to the lack of groundwater and ground subsidence, we propose a sponge city-sized rainwater diversion device to solve the above problems
