Urban pavement rainwater collection system

Abstract

The invention belongs to the technical field of rainwater collection, and particularly relates to an urban pavement rainwater collection system which comprises an elevated body and a protective fence.A precipitation tank is formed in the surface of one side, close to the protective guard, of the elevated body; funnel-shaped drain outlets are uniformly formed in the bottom of the precipitation tank; precipitation plates are fixedly connected to the two sides of the elevated body; the precipitation plate is designed to be arc-shaped; flow guide openings which are uniformly distributed are formed in one side of the precipitation tank; the lower surface of the precipitation plate is fixedly connected with a flow guide plate; one end of the flow guide plate is communicated with a rainwater well for collecting rainwater; a diaphragm is fixedly connected between the surface of the precipitation plate and the side wall of the protective fence; a screw rod is connected into the cleaning groovein a sliding manner; rainwater can be preliminarily precipitated in the rainwater collecting process, precipitates are discharged into afforestation, instant and effective rainwater utilization is achieved, meanwhile, when the rainfall is large, part of rainwater can be directly used for irrigation afforestation, and the water collecting pressure of a rainwater well is reduced.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection, in particular to an urban pavement rainwater collection system. Background technique [0002] With the further acceleration of urbanization, the contradiction of urban water shortage has further deepened, and environmental and ecological problems have also expanded simultaneously. my country is a very water-scarce country. The current per capita water resources share is only 1 / 4 of the global per capita water resources share. More than 300 cities are water-scarce cities. Due to the rapid development of urbanization and the expansion of impermeable areas such as roads and buildings, on the one hand, rainwater can no longer infiltrate into the ground to replenish groundwater, deteriorating the water environment and ecological environment around the city; on the other hand, runoff quickly gathers during heavy rain Cause ground water and local flooding in the city. [0003] In order to...

[0009] 3. After the rainwater is collected in the rainwater well, take it out to water the green plants through the rainwater well, which is too wasteful of manpower and material resources, and the rainwater will completely enter the rainwater well, which will cause more rainwater accumulation in the rainwater well, and continuous rainfall will lead to the paralysis of the rainwater well
