Rainwater circulating device of sponge city

Abstract

The invention discloses a rainwater circulating device of a sponge city. The rainwater circulating device of the sponge city comprises a body. The upper end of the body is provided with a rainwater collecting hopper used for collecting rainwater. The lower end of the rainwater collecting hopper is connected with a water inlet at the upper end of the main water storage tank in the body. The main water storage tank is connected with a water conveying pipeline which is externally connected. The two sides of the main water storage tank are symmetrically provided with movable auxiliary water storage tanks communicating with the main water storage tank. The side walls of the body are provided with openings used for extending and retracting motion of the auxiliary water storage tanks. In a limited space, the rainwater circulating device of the sponge city improves the rainwater collecting capacity and is provided with multiple rainwater collecting faces to collect rainwater and provided withmultiple storage cavities communicating with one another, the water storage capacity of the device is improved, and full utilization and establishment of the sponge city are facilitated; and the rainwater circulating device of the sponge city is simple in structure, high in practicability and easy to use and popularize.

Description

technical field [0001] The invention relates to the field of circulation devices, in particular to a sponge city rainwater circulation device. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and releases and uses the stored water when needed. , Gradually improve and restore the city's natural ecological balance. In the process of sponge city construction, people and natural ecology should be the priority principle, so it is defined as an ecological sponge city. [0003] Many southern cities in my country have relatively large rainfall. These cities with high rainfall have the inherent conditions for building sponge cities. During the urban rainfall process, a large amount of rainwater falls to the ground and becomes sewage through sewers, causing a lot of waste. The first p...

[0003] Many southern cities in my country have relatively large rainfall. These cities with high rainfall have the inherent conditions for building sponge cities. During the urban rainfall process, a large amount of rainwater falls to the ground and becomes sewage through sewers, causing a lot of waste. The first priority for the establishment of sponge cities The task is to carry out efficient water storage for rainwater, so a rainwater recycling device that is easy to implement and has high rainwater collection efficiency is required
