Description

Technical Field

[0001] This invention relates to the field of electromagnetic water meter technology, specifically to an antifreeze electromagnetic water meter. Background Technology

[0002] An electromagnetic water meter is a flow metering device designed based on Faraday's law of electromagnetic induction. It features high precision, high stability, and anti-interference capabilities. In agricultural irrigation, electromagnetic water meters can monitor the water consumption and flow rate of farmland irrigation in real time, helping farmers to rationally adjust irrigation plans and reduce water waste.

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

[0004] In cold weather, the internal parts of the water meter are prone to damage, leading to inaccurate measurement or malfunction. Furthermore, the water flow inside the pipes connected to the electromagnetic water meter can be affected by the weather, affecting the accuracy of the electromagnetic water meter's measurement. Summary of the Invention

[0005] The purpose of this invention is to provide an antifreeze electromagnetic water meter to solve the problems mentioned in the background art, such as the easy damage of internal components of the water meter, which leads to inaccurate measurement or failure to operate normally, and the fact that the water flow inside the pipe connected to the electromagnetic water meter can also be affected by weather, resulting in inaccurate water flow measurement by the electromagnetic water meter.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an antifreeze electromagnetic water meter, comprising a pipe, wherein a first circulation ring and a second circulation ring are provided at both ends of the outer side of the pipe, the inner wall of the second circulation ring is provided with multiple grooves, and multiple sets of first-branch plates are fixed inside the second circulation ring. The first-branch plates separate the water flow into two streams, which then come into contact with the second friction grooves. The outer side of the first-branch plates is provided with second friction grooves. The inner side of the second circulation ring is provided with a connection port on one side of the first-branch plates, and a connecting pipe is provided inside the connection port. The connecting pipes are evenly distributed on the outer side of the pipe for antifreeze and protection of the electromagnetic water meter. The end of the connecting pipe is connected to the first circulation ring.

[0007] Preferably, a second water inlet is provided at the bottom of the second circulation ring. When water flows into the second water inlet through the first water inlet, it will not affect the measurement of the electromagnetic water meter. The electromagnetic water meter is located at the outlet. A return pipe is provided at the top of the first circulation ring. By opening the valve, the water at the first water inlet flows through the second water inlet and the return pipe. A valve is provided inside the return pipe, and the water flows back through the return pipe, so that the water in the first water inlet flows back to the original water storage position, so that the water in the pipe and the external pipe are connected to flow, preventing the water from freezing due to prolonged stagnation.

[0008] Preferably, the grooves are evenly distributed on the inner wall of the second circulation ring, and the first and second circulation rings have the same structure.

[0009] Preferably, the second water inlet is connected to a pipe, and threaded holes are provided at both ends of the pipe, and fixing plates are provided at both ends inside the pipe.

[0010] Preferably, the outer side of the fixed plate is provided with a friction groove, one end of the pipe is provided with a water inlet, the other end of the pipe is provided with a water outlet, the outer side of the pipe is connected to an external pipe, and the material inside the first circulation ring and the second circulation ring is a wear-resistant and environmentally friendly material such as granite, so that the water flow can better contact with it.

[0011] Preferably, a valve is installed in the middle of the pipeline to control the flow of water in the pipeline, an electromagnetic water meter is installed at the top of the pipeline, a first circulation coil and a second circulation coil are set on both sides of the electromagnetic water meter, and connecting pipes are evenly arranged on the outside of the pipeline to protect the pipeline.

[0012] Preferably, the inner side of the second circulation ring is provided with tapered tubes on both sides of the second water inlet. The heat generated by the friction between the water flow and the second branch plate, and between the first branch plate and the groove, can effectively protect the electromagnetic water meter from freezing. The end of the tapered tube is provided with multiple sets of second branch plates. The water flow will make rapid contact (friction) with the groove through the second branch plate, the first branch plate, and the groove. According to the law of conservation of energy and the principle of frictional heat generation, mechanical energy (the kinetic energy of the water flow) will do work in this process, generating heat.

[0013] Preferably, a third friction groove is provided on the outer side of the second fork plate, and a water spray nozzle is provided at the first end of the tapered tube. The water spray nozzle is used to spray water out quickly so that it contacts the first fork plate and the groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. To prevent the water in the pipeline and the electromagnetic water meter from freezing, the valve is opened to allow water at the No. 1 inlet to flow through the No. 2 inlet and the return pipe. The water flows back through the return pipe, returning the water in the No. 1 inlet to its original storage location. This allows the water in the pipeline and the external pipeline to flow, preventing the water from freezing due to prolonged stagnation. Furthermore, when the water flows from the No. 1 inlet to the No. 2 inlet, it does not affect the measurement of the electromagnetic water meter, which is located at the outlet.

[0016] 2. The No. 2 and No. 1 branch plates make rapid contact (friction) with the grooves. During this process, mechanical energy (the kinetic energy of the water flow) does work, generating heat. The No. 1 and No. 2 circulation rings are set on both sides of the electromagnetic water meter, and the connecting pipes are evenly set on the outside of the pipe to protect the pipe. The heat generated by the friction between the water flow and the No. 2 and No. 1 branch plates and the grooves can effectively protect the electromagnetic water meter from freezing. Moreover, when the water in the pipe is still for a long time, microorganisms in the water, such as bacteria and algae, will use the nutrients in the water to grow and reproduce. Making the water flow prevents them from multiplying in the pipe. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 , 2 3, 4, The present invention provides a technical solution for an antifreeze electromagnetic water meter: an antifreeze electromagnetic water meter includes a pipe 1, with a first circulation ring 2 and a second circulation ring 3 at both ends of the outer side of the pipe 1. The inner wall of the second circulation ring 3 is provided with multiple grooves 301. Multiple sets of first branch plates 302 are fixed inside the second circulation ring 3. The first branch plates 302 are used to split the water flow into two streams and make contact with the second friction grooves 303. The outer side of the first branch plates 302 is provided with the second friction grooves 303. The inner side of the second circulation ring 3 is provided with a connection port 308 on one side of the first branch plates 302. The connection port 308 is provided with a connecting pipe 304. The connecting pipes 304 are evenly arranged on the outer side of the pipe 1 for the antifreeze and protection of the electromagnetic water meter 104. The end of the connecting pipe 304 is connected to the first circulation ring 2.

[0025] The bottom of the second circulation loop 3 is equipped with a second inlet 305. When water flows into the second inlet 305 through the first inlet 105, it does not affect the measurement of the electromagnetic water meter 104. The electromagnetic water meter 104 measures at the outlet. The top of the first circulation loop 2 is equipped with a return pipe 306. By opening the valve 307, water at the first inlet 105 flows through the second inlet 305 and the return pipe 306. A valve is installed inside the return pipe 306. 307. Water flows back through return pipe 306, allowing the water in inlet 105 to return to its original storage location, enabling water flow between pipe 1 and the external pipe, preventing the water from freezing due to prolonged stagnation. Grooves 301 are evenly distributed on the inner wall of circulation ring 3. Circulation ring 2 and circulation ring 3 have the same structure. Inlet 305 is connected to pipe 1. Threaded holes 101 are provided at both ends of pipe 1. Fixing plates 102 are provided at both ends inside pipe 1.

[0026] In this embodiment: by opening valve 307, water at the first inlet 105 flows through the second inlet 305 and the return pipe 306. The water flows back through the return pipe 306, allowing the water in the first inlet 105 to return to its original storage location. This allows water to flow between pipe 1 and the external pipe, preventing the water from freezing due to prolonged stagnation. Furthermore, when water flows from the first inlet 105 into the second inlet 305, it does not affect the measurement of the electromagnetic water meter 104, which measures at the outlet.

[0027] Please see Figure 1 , 3 5. A friction groove 103 is provided on the outer side of the fixed plate 102. A water inlet 105 is provided at one end of the pipe 1 and a water outlet is provided at the other end of the pipe 1. An external pipe is connected to the outer side of the pipe 1. The material inside the first circulation ring 2 and the second circulation ring 3 is a wear-resistant and environmentally friendly material such as granite, so that the water flow can better contact it. A valve is provided in the middle of the pipe 1 to control the flow of water in the pipe 1. An electromagnetic water meter 104 is installed on the top of the pipe 1. The first circulation ring 2 and the second circulation ring 3 are located on both sides of the electromagnetic water meter 104. The connecting pipe 304 is evenly arranged on the outer side of the pipe 1 to protect the pipe 1.

[0028] Inside the second circulation ring 3, conical tubes 4 are installed on both sides of the second inlet 305. The heat generated by the friction between the water flow and the second branch plate 402, the first branch plate 302, and the groove 301 can effectively protect the electromagnetic water meter 104 from freezing. Multiple sets of second branch plates 402 are installed at the ends of the conical tubes 4. The water flow will rapidly contact and rub against the groove 301 through the second branch plate 402, the first branch plate 302, and the groove. According to the law of conservation of energy and the principle of frictional heat generation, the mechanical energy of the water flow will do work during this process, generating heat. A third friction groove 403 is installed on the outer side of the second branch plate 402. A spray nozzle 401 is installed at the beginning of the conical tube 4, which is used to rapidly spray the water flow, allowing it to contact the first branch plate 302 and the groove 301.

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

[0030] Working principle:

[0031] Pipe 1 is connected to an external pipe through threaded hole 101. Water flows by opening the valve in 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 electromotive force. When the valve in pipe 1 is closed, the water flow in the pipe is static. To prevent the water in the pipe and the electromagnetic water meter 104 from freezing, valve 307 is opened to allow the water at the first inlet 105 to flow through the second inlet 305 and the return pipe 306. The water flows back through the return pipe 306, allowing the water in the first inlet 105 to return to its original storage position. This allows the water in pipe 1 and the external pipe to flow, preventing the water from freezing due to prolonged static flow. When the water flows through the first inlet 105 into the second inlet 305, it does not affect the measurement of the electromagnetic water meter 104. The electromagnetic water meter 104 measures at the outlet position.

[0032] During the water recirculation process, the water flow will rapidly contact (friction) the groove 301 through the second branch plate 402, the first branch plate 302, and the groove 301. According to the law of conservation of energy and the principle of frictional heat generation, when the water flow rapidly contacts the surface of an object and generates relative motion (i.e., friction), a portion of the mechanical energy will be converted into internal energy. The frictional force between the molecules on the surface of the object and the water molecules will hinder their relative motion. During this process, the mechanical energy (the kinetic energy of the water flow) will do work, generating heat. The first circulation coil 2 and the second circulation coil 3 are located on both sides of the electromagnetic water meter 104, connected by a pipe. 304 is evenly arranged on the outside of pipe 1 to protect pipe 1. The heat generated by the friction between the water flow and the second branch plate 402, the first branch plate 302 and the groove 301 can effectively protect the electromagnetic water meter 104 from freezing. When the water in the pipe is stagnant for a long time, microorganisms in the water, such as bacteria and algae, will use the nutrients in the water to grow and reproduce. By installing an external timer device, the valve 307 can be opened at a time to control the backflow and make the water flow regularly without the need for an external heating device.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
