Efficient water-saving communicating vessel irrigation water source system

Abstract

The invention provides an efficient water-saving communicating vessel irrigation water source system, relates to the field of agriculture and forestry irrigation, and aims to provide a water source solution for efficient water-saving irrigation. According to the solution, on the basis of the communicating vessel principle, finite water source points are transferred and copied according to required irrigation positions and the number, and the large grid-shaped communicating vessel irrigation water source system composed of a reservoir, a pipe network and a multifunctional water taking device is built in an engineering method. The efficient water-saving communicating vessel irrigation water source system is characterized in that non-power water conveying, automatic non-power water transferring and automatic pollution discharge can be achieved; the system is composed of independent system units which can constitute a large-scale irrigation water source network. By means of the solution, water sources can be completely and conveniently provided for efficient water-saving irrigation with low cost.

Description

technical field [0001] The invention relates to agriculture and forestry irrigation, in particular to providing convenient and cheap water sources for high-efficiency water-saving irrigation. Background technique [0002] High-efficiency water-saving irrigation involves three main aspects: water source construction, water delivery and improvement of water use methods. Among them, providing a water source that is easy to use and low in cost is the first problem that needs to be solved. [0003] The current high-efficiency water-saving irrigation practices mainly focus on the promotion of pipeline water delivery methods, the use of advanced irrigation technology and irrigation equipment, and the core is to try to improve water use efficiency. However, improving water use efficiency cannot improve water intake conditions and reduce water prices, and efficient water-saving irrigation will be difficult to promote without convenient and cheap water sources. [0004] In the prese...

AI Technical Summary

Problems solved by technology

[0007] 1. Low utilization rate of pipe network

According to the 150m on both sides of the pipeline should be the benefit area, the 3000km pipeline should benefit 900 square kilometers or 1.35 million mu of cultivated land, but the actual benefit area is only 470,000 mu, and the utilization rate of the pipeline network is less than 35%.

[0008] 2. The pipeline cost per unit length is high

Although the underground channel water delivery method does not need to consume power, the flow velocity in the pipe is slow. When the flow requirements are the same, a larger pipe diameter is required, and the material cost and construction cost of the pipe network are higher.

[0009] 3. The pipe network is prone to blockage

[0010] 4. Cannot effectively reduce the cost of water use

This area is a rice planting area, so self-flow irrigation should be used, but because the water level inside the pipeline is lower than the ground, it still needs power to draw water during irrigation
