Description
Technical Field
The invention relates to the technical field of intelligent irrigation of farmlands, in particular to an intelligent irrigation ball valve and an irrigation system.
Background
The shortage of water resources has become a global problem, and saving water and realizing efficient water use are demands for human survival and development and also demands of the global economic society. Water resource is likely to be another resource in short supply faced by human beings following petroleum resources, which is a reality that we cannot avoid. As one of the water-poor countries in China, the water-poor countries have a large number of people and are in the period of economic construction and development, and the demand on water resources is increasing day by day. As the agricultural water occupies 70 percent of the total water consumption in China, and the problems of low agricultural irrigation efficiency and water waste are ubiquitous, the contradiction between water shortage and irrigation area increase is increasingly excited. In order to relieve the shortage of water resources and realize high and stable yield of crops, automatic intelligent control needs to be reasonably popularized in an automatic irrigation system.
At present, farmland irrigation in China mostly stays in a traditional irrigation mode mainly controlled manually, particularly in rotation irrigation, a user needs to walk to the field at intervals of a period of time, for example, every 3-6 hours during corn field irrigation, the valve of an irrigated area is manually closed and the valve of an area to be irrigated is manually opened, when the irrigation area is large, the valves are numerous, the labor investment is large, the time consumption is long, and the valves are not opened and closed timely, so that the waste of manpower resources and water resources is caused, the irrigation quantity is not convenient to accurately control, and the crop growth is extremely unfavorable.
In order to solve the problems, the existing automatic agricultural irrigation machine, especially, the automatic control of an irrigation valve adopts the electromagnetic valve control, but the electromagnetic valve can be started only by pressing certain pressure, and the control is controlled by a switch, only the opening and closing of a valve body can be realized, during irrigation, especially during drip irrigation operation, the control of the pipeline pressure depends on artificial experience, the randomness is large, scientific data support is not available in the whole irrigation process, if a slope exists in an irrigation area, the water outlet pressure of water outlet piles at different slopes is different, the phenomenon of pipeline breakage or pipe explosion is easy to occur, irrigation water and fertilizer application are easy to result, the water and fertilizer utilization rate is low, the resource is seriously wasted (the water and fertilizer utilization rate is only about 40%), and the agricultural planting problems such as soil structure damage and environmental pollution are further bred.
In the existing intelligent irrigation system, in order to facilitate the implementation of the wheel irrigation, a switching head comprising a water inlet and a plurality of water outlets, such as a three-way pipe or a five-way pipe, is generally arranged on the ground surface water outlet pile, and the positions of the water outlets of the three-way pipe or the five-way pipe are respectively provided with an electromagnetic valve, so that a plurality of electromagnetic valves are required to be arranged on one ground surface water outlet pile. And when the rotation is irrigated, need control a plurality of solenoid valves simultaneously, will cause intraductal water pressure fluctuation a little carelessly, and then produce the water hammer phenomenon, irrigation hose or hollow billet are very easily taken off the pipe or the tube explosion, have greatly shortened intelligent irrigation system's life. When the hose is butted with the valve body pipeline in the field, in order to prevent water leakage, an installer generally winds the hose and the valve body pipeline by using a plastic film, a water stop belt and the like at a joint, and the plastic film and the water stop belt are directly discarded after irrigation to become farmland plastic garbage which is extremely difficult to degrade, so that great influence is generated on the sustainable development of the natural environment and the farmland.
In addition, in the existing electromagnetic valve control system, machine rooms for arranging the transmitting base stations are required to be established on the field, one transmitting base station can only control the electromagnetic valve within the range of 1-10 kilometers of a square circle, and once the range is exceeded, the electromagnetic valve is not controlled any more, so that when the area of the field is large, a plurality of transmitting base stations and machine rooms are required to be established, the cost is very high, and the large-area popularization and application cannot be realized. When the electromagnetic valve works, power needs to be continuously supplied to maintain the opening state of the electromagnetic valve, so that the power consumption is large, the volume of the energy storage module is heavy, the cost is high, the block chain agricultural management system is extremely unfavorable to be established, and the development of intelligent agriculture is seriously influenced.
