Annular pipe network irrigation system

Abstract

The invention discloses an annular pipe network irrigation system. The annular pipe network irrigation system comprises a first part, a main pipe, sub-main pipes, water supply plugs, branch pipes, andcapillary pipes, wherein the first part comprises a pressurization system and a filtration system, the first part communicates with a water source, the main pipe communicates with the first part, thesub-main pipes communicate with the main pipe, the water supply plugs are arranged on the sub-main pipes, the branch pipes communicate with the sub-main pipes through the water supply plugs, the capillary pipes communicate with the branch pipes, the sub-main pipes are at least two, one end of each sub-main pipe communicates with the main pipe, the other ends of the sub-main pipes communicate witheach other, and an annular pipe network is formed between the main pipe and the sub-main pipes. The system has the advantages of small water loss, stable water supply, convenient maintenance and highpipeline utilization rate, and is mainly used for conveying water in farmland irrigation systems.

Description

technical field [0001] The invention belongs to farmland irrigation systems, in particular to a field water-saving irrigation water delivery and distribution pipeline layout system. Background technique [0002] In the prior art, the pipe network layout in the agricultural irrigation system is a tree structure. That is, the farmland irrigation pipe network system, especially the drip irrigation system, is divided into the head, the main pipe, the branch pipe, the water supply plug, the branch pipe, and the capillary pipe. The head includes the head pressurization system and the filtration system. The branch pipe is connected with the main pipe, and the water supply plug is set on the branch pipe. The other end is blocked or connected to the drainage well to form a tree structure. Generally, irrigation projects constructed with such a tree structure lack pressure regulating facilities. The water supply plugs are arranged in sequence along the branch pipes. The pressure at ea...

That is, the farmland irrigation pipe network system, especially the drip irrigation system, is divided into the head, the main pipe, the branch pipe, the water supply plug, the branch pipe, and the capillary pipe. The head includes the head pressurization system and the filtration system. The branch pipe is connected with the main pipe, and the water supply plug is set on the branch pipe. The other end is blocked or connected to the drainage well to form a tree structure. Generally, irrigation projects constructed with such a tree structure lack pressure regulating facilities. The water supply plugs are arranged in sequence along the branch pipes. The pressure at each water supply plug Unbalanced, resulting in uneven capillary water output on the connected branch pipe; each water supply plug is supplied by a single branch pipe, if the branch pipe or water supply plug fails, the water flow at that place must be cut off for maintenance, so that the The water supply cocks on the sub-main pipes cannot be used for irrigation, and the reliability of the system’s water supply is poor; one end of the capillary pipe is connected to the branch pipe as the water inlet of the capillary pipe, and the other end is blocked to prevent water from flowing. With this structure, the laying length of the branch pipe is short, and the water output of the capillary pipe is not large. Uniform, the capillary tube is not easy to wash; and there is a water interception device between the sub-main pipe and the main pipe, each sub-main pipe is set independently, and each wheel irrigation area is equipped with a separate water interception device, which is turned on and off in turn according to the different wheel irrigation areas The water interception device enables different sub-main pipes to deliver water. Some pipes are idle during irrigation, the utilization rate of the pipes is low, the energy consumption is high, the cost is high, and the operation stability and reliability are poor.
