Rainwater storage irrigation system for green belts under viaducts

Abstract

The invention provides a rainwater storage irrigation system for green belts under viaducts. The rainwater storage irrigation system comprises a water storage tank, a fresh rain primary filtration and separation device, a photovoltaic pump, an energy supply device, a spray head and a microcomputer centralized control box, wherein the fresh rain primary filtration and separation device comprises a filter screen, a base, a fresh rain separation water tank, a drain pipe and a first overflow pipe; the filter screen, the base and the fresh rain separation water tank are assembled in sequence from top to bottom; the first overflow pipe is communicated with the water storage tank; the photovoltaic pump is arranged in the water storage tank; the energy supply device is used for providing power for the photovoltaic pump, and comprises a solar photovoltaic plate and an energy storage inverter; the spray head is connected with the photovoltaic pump; and the microcomputer centralized control cabinet is in signal connection with the photovoltaic pump. The rainwater storage irrigation system provided by the invention is capable of removing massive harmful substances in the rainwater so as to prevent harmful substances from adversely influencing the growth of green plants, and sufficiently utilizing the rainwater resource and the solar energy so as to achieve energy conservation and environment protection functions; and moreover, the rainwater storage irrigation system is automatic in the process from primary filtration and separation to rainwater storage to spray irrigation and flood irrigation, so that the labor cost is reduced to the greatest extent and the work efficiency is improved.

Description

technical field [0001] The invention relates to a rainwater regulation and storage irrigation system, in particular to a rainwater regulation and storage irrigation system for green belts under viaducts. Background technique [0002] The important speech "On the Construction of Ecological Civilization" mentioned that when upgrading the urban drainage system, it is necessary to give priority to retaining limited rainwater, give priority to more use of natural power to drain water, and build a "sponge city" of natural accumulation-natural infiltration-natural purification ". The so-called sponge city is a new generation of urban stormwater management concept, which means that the city 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 stormwater system construction". When it rains, it absorbs, stores, infiltrat...
