Pipe condition control intelligent irrigation valve, irrigation system and irrigation method

Abstract

The invention discloses a pipe condition control intelligent irrigation valve, an irrigation system and an irrigation method. After an electric valve opening degree control device receives in-pipe fluid information transmitted by a pipe condition detection sensor, a valve element of an electric valve is driven to rotate to the proper valve opening degree according to preset fluid information, thewater amount, pressure and flow speed in a water hose are accurately controlled, accurate water and fertilizer irrigation is achieved, the problems of pipe disengaging or pipe bursting, the water hammer phenomenon, water and fertilizer waste, water and fertilizer pipe wall corrosion and the like caused by pressure differences can be avoided, a block chain agricultural management system can be conveniently built, and intelligent agricultural management on the national scale becomes possible. A sensing element of the pipe condition detection sensor stretches into the water hose through a probe protection structure. The structure is simple and reliable, installation is convenient, on the basis of effectively obtaining the in-pipe fluid information, the sensing element is protected against impact damage, the detection cost of the intelligent irrigation system is greatly reduced, and large-area application and popularization are convenient.

Description

technical field [0001] The invention relates to the technical field of intelligent irrigation valves, in particular to an intelligent irrigation valve for condition control, an irrigation system and an irrigation method. Background technique [0002] The shortage of water resources has become a global problem. Saving water and achieving efficient water use is the need for human survival and development, as well as the needs of the global economy and society. Water resources are likely to be another scarce resource faced by human beings after petroleum resources. This is a reality that we cannot avoid. As one of the water-poor countries, our country has a large population and is in the period of economic construction and development, so the demand for water resources is increasing day by day. Since agricultural water accounts for 70% of my country's total water consumption, and the problems of low agricultural irrigation efficiency and water waste are common, the contradicti...

Problems solved by technology

[0003] The existing automatic agricultural irrigation machinery, especially the automatic control of the irrigation valve, adopts the solenoid valve control, but the solenoid valve needs a certain pressure to start, and it is controlled by the switch, which can only realize the opening and closing of the valve body. , especially in drip irrigation operations, the control of pipeline pressure depends on human experience, which is very random, and there is no scientific data support in the entire irrigation process. The phenomenon of pipe rupture or pipe burst will lead to random irrigation water and fertilization, low utilization rate of water and fertilizer, serious waste of resources (the utilization rate of water and fertilizer is only about 40%), and long-term random control will cause soil structure damage and environmental pollution. agricultural planting issues
