Self-service circulating drainage and irrigation system in irrigation and water conservancy

Abstract

The invention relates to a self-service circulating drainage and irrigation system in the field of drainage and irrigation in irrigation and water conservancy, comprising nine parts, namely a water and moisture retention device, a water collecting and filtering device, a water distributing and deflecting device, a water storage and preparation device, a water inlet and outlet device, a water drainage and supply device, a water extraction and control device, a gas and water delivery device, and a water extraction and irrigation device, wherein a series of drainage and irrigation facilities is interconnected by supporting combination to form three types of self-service circulating drainage and irrigation technologies mainly including an underground drainage and irrigation method, a ground drainage and irrigation method and an interactive drainage and irrigation method; each drainage and irrigation method has the characteristics of self-service water collection, storage and drainage for preventing waterlogging in the situation of rainfall, self-service water, moisture and irrigation retention for preventing drought in the situation of drought, and the like; the system facility can be directly buried under farmland as underground drainage and irrigation works, and has the advantages of simple construction structure and low building cost, does not occupy cultivated land of the farmland or affect farming operations, and does not need maintenance for a plurality of years or one hundred years after one-time building, thus greatly saving resource cost; and the self-service circulating drainage and irrigation system can be widely applied in the fields of agriculture, forestry, greening, landscape, water-saving projects and the like.

Description

technical field [0001] The invention relates to a self-service circulation drainage and irrigation system in the field of agricultural water conservancy drainage and irrigation, especially in the area of ​​"rainy waterlogging and drought and water shortage", which can provide self-service rainwater collection, drainage and waterlogging prevention, soil conservation and water storage, closure and disaster reduction in rainy conditions And in times of drought, there are three kinds of self-service circulating irrigation and drainage systems and special drainage and irrigation facilities, which can be self-help water retention and moisturizing, water saving and irrigation, irrigation for drought prevention, energy saving and disaster reduction, underground drainage and irrigation, surface drainage and irrigation and interactive drainage and irrigation.

Problems solved by technology

[0002] 1. my country is a large agricultural country. Water conservancy projects and irrigation and drainage agriculture play a very important role in agricultural production. However, my country's water resources are seriously insufficient, and the foundation of water conservancy facilities is lacking. Water and soil erosion and waste of water resources are common in agricultural irrigation and drainage, and at the same time cause agricultural ecological problems. Environmental issues
