Building rainwater recycling system used for sponge city

Abstract

The invention discloses a building rainwater recycling system used for a sponge city. The system comprises a collecting box fixedly mounted at the top of a building and a water storage well arranged on the ground. A supporting column is fixedly mounted on the top surface of the collecting box. Collecting fabric capable of collecting rainwater is fixedly mounted on collecting plates. When a collecting cavity is full of collected rainwater, a floating ball is made to move upwards and upwards drives a push rod to slide upwards, a valve element enables a collecting pipe to communicates with a communicating pipe, water is not collected into the collecting cavity any more, collected water in the collecting cavity overflows outwards through a first overflow pipe, the collecting plates can be propped open when it rains, rainwater collecting is performed, in addition, the collected rainwater is filtered primarily, resource wasting is reduced, when wind on the building is excessively strong, the collecting plates can be controlled to be closed and are prevented from being damaged by the strong wind, the collected rainwater can also be directly introduced into the water storage well, no ground waterlogging is caused, and water supply is guaranteed.

Description

technical field [0001] The invention relates to the field of municipal administration, in particular to a rainwater recovery system for buildings in a sponge city. Background technique [0002] Sponge city refers to a city that, like a sponge, has good flexibility in adapting to environmental changes and responding to natural disasters caused by rain. When it rains, it absorbs, stores, infiltrates, and purifies water. Release and use it to realize the free migration of rainwater in the city. [0003] For some buildings, water supply is one of the most basic constructions of a building. At present, the roofs of many buildings directly drain the collected rainwater to the downstairs through pipes. Extraction from above is a waste of resources, and some rainwater recovery systems have a large collection area and occupy a large volume. The collected rainwater contains a large amount of solid impurities and cannot be directly supplied to buildings. Contents of the invention ...
