In agricultural irrigation, the electromagnetic water meter can monitor the water consumption and flow of farmland irrigation in real time, helping farmers to reasonably adjust irrigation plans and reduce water waste.

[0003] When water flows through the pipe of the existing electromagnetic water meter, a certain electromotive force will be generated due to the movement of water molecules. This electromotive force can be detected by the electrodes inside the water meter. The electrodes calculate the water flow rate by detecting the changes in the electromotive force.

[0025] A No. 2 water inlet 305 is provided at the bottom of the No. 2 circulation circle 3. When water flows into the No. 2 water inlet 305 through the No. 1 water inlet 105, it does not affect the measurement of the electromagnetic water meter 104. The measurement position of the electromagnetic water meter 104 is set at the position of the water outlet. A return pipe 306 is provided at the top of the No. 1 circulation circle 2. By opening the valve 307, the water at the No. 1 water inlet 105 flows through the No. 2 water inlet 305 and the return pipe 306. A valve is provided inside the return pipe 306. 307, water refluxes through the reflux pipe 306, so that the water in the No. 1 water inlet 105 flows back to the original water storage position, so that the water in the pipeline 1 and the external pipeline flows, and prevents the water flow from being frozen due to long-term stagnation.

[0026] In this embodiment: by opening the valve 307, the water at the position of the No. 1 water inlet 105 flows through the No. 2 water inlet 305 and the return pipe 306, and the water flows back through the return pipe 306, so that the water in the No. 1 water inlet 105 flows back to the original water storage position, and the water in the pipeline 1 and the external pipeline flows, preventing the water flow from being frozen due to long-term stagnation, and when the water flows through the No. 1 water inlet 105 and enters the No. 2 water inlet 305, it will not affect the measurement of the electromagnetic water meter 104.

[0027] See also Figure 1 , 3 5. A No. 1 friction groove 103 is arranged on the outside of the fixed plate 102. A No. 1 water inlet 105 is arranged at one end of the pipe 1, and a water outlet is arranged at the other end of the pipe 1. The outside of the pipe 1 is connected with an external pipe.

[0028] Conical tubes 4 are arranged on both sides of the No. 2 water inlet 305 inside the No. 2 circulation circle 3. The heat generated by the friction between the water flow and the No. 2 bifurcation plate 402, the No. 1 bifurcation plate 302 and the groove 301 can well protect the electromagnetic water meter 104 from freezing. Multiple groups of No. 2 bifurcation plates 402 are arranged at the end of the conical tube 4. The water flow will quickly contact and rub through the No. 2 bifurcation plate 402, the No. 1 bifurcation plate 302 and the groove 301. According to the law of conservation of energy and the principle of frictional heat generation, the kinetic energy of the mechanical energy of the water flow will do work in this process, causing it to generate heat.

[0029] In this embodiment: the water flow will quickly contact (friction) with the groove 301 through the second bifurcation plate 402, the first bifurcation plate 302. According to the law of conservation of energy and the principle of frictional heat generation, when the water flow quickly contacts the surface of an object and generates relative motion (i.e. friction), a part of the mechanical energy will be converted into internal energy, and the friction between the molecules on the surface of the object and the water molecules will hinder their relative motion. In this process, the mechanical energy (kinetic energy of the water flow) will do work and generate heat. The first circulation ring 2 and the second circulation ring 3 are arranged on both sides of the electromagnetic water meter 104, and the connecting pipe 304 is evenly arranged on the outside of the pipeline 1 to protect the pipeline 1. The heat generated by the friction between the water flow and the second bifurcation plate 402, the first bifurcation plate 302 and the groove 301 can well protect the electromagnetic water meter 104 from freezing.

[0030] Working principle:

[0031] The pipe 1 is connected to an external pipe through a threaded hole 101. The water flows by opening the valve in the pipe 1. When the water flows through the electromagnetic water meter 104, the rotor rotates accordingly. The magnet inside the rotor interacts with the electromagnetic coil to generate an electromotive force. The electrode calculates the water flow by detecting the change in the electromotive force. When the valve of the pipe 1 is closed, the water flow in the pipe is in a static state. In order to prevent the water in the pipe and the electromagnetic water meter 104 from being frozen, the valve 307 is opened to allow the water at the position of the No. 1 water inlet 105 to flow through the No. 2 water inlet 305 and the return pipe 306. The water flows back through the return pipe 306, so that the water in the No. 1 water inlet 105 flows back to the original water storage position, so that the pipe 1 and the water in the external pipe flow, and the water flow is prevented from being frozen due to long-term static. When the water flows into the No. 2 water inlet 305 through the No. 1 water inlet 105, it does not affect the measurement of the electromagnetic water meter 104. The measurement position of the electromagnetic water meter 104 is set at the position of the water outlet.

[0032] When the water is refluxed, the water will quickly contact (friction) with the groove 301 through the second bifurcation plate 402 and the first bifurcation plate 302. According to the law of conservation of energy and the principle of frictional heat generation, when the water quickly contacts the surface of an object and generates relative motion (i.e. friction), part of the mechanical energy will be converted into internal energy, and the friction between the molecules on the surface of the object and the water molecules will hinder their relative motion. In this process, the mechanical energy (kinetic energy of the water flow) will do work and generate heat. The first circulation ring 2 and the second circulation ring 3 are arranged on both sides of the electromagnetic water meter 104, and the connecting pipe 304 is evenly arranged on the outside of the pipeline 1 to protect the pipeline 1. The heat generated by the friction between the water flow and the second bifurcation plate 402, the first bifurcation plate 302 and the groove 301 can effectively protect the electromagnetic water meter 104 from freezing. When the water in the pipeline is stagnant for a long time, microorganisms in the water, such as bacteria, algae, etc., will use the nutrients in the water to grow and reproduce. An external timing device can be used to control the valve 307 to open at a time, thereby controlling the reflux and making the water flow regularly without the need for an external heating device.
