Abstract

The invention discloses a zero-energy-consumption rainwater irrigation system. The zero-energy-consumption rainwater irrigation system comprises a water storage tank, an air force water lifting device, a water tank and an irrigation subsystem which are sequentially connected through a pipeline. An overflow pipe connected with the water storage tank is arranged on the water tank, and a valve is arranged on the pipeline connecting the water tank with the irrigation subsystem. Rainwater is lifted to a certain height by air energy, so that a certain potential energy is generated, and much energy source consumption is reduced by rainwater which can automatically flow. Efficient utilization of the rainwater can be realized, and municipal water pressure can be alleviated. Automatic or remote control of rainwater irrigation can be realized, labor investment of municipal personnel is reduced, and external energy source for the integral system is not required.

Description

technical field [0001] The invention relates to a rainwater utilization technology, which is a rainwater irrigation system with zero energy consumption. Background technique [0002] my country is a country with poor water resources. The per capita water resources are only 2,300 cubic meters, accounting for about 1 / 4 of the world's average level. -3000 cubic meters). The distribution of my country's water resources is extremely uneven. 81% of the country's water resources are concentrated in the Yangtze River and the areas south of it. Most of the northern cities suffer from severe water shortages. At the same time, with the continuous acceleration of the urbanization process, the water consumption of industrial and agricultural construction and residential water consumption is increasing year by year, and the shortage of water resources has become one of the key factors affecting the sustainable development of my country's social economy. As a natural resource, rainwater c...
