[0044] Please refer to all the drawings. In an illustrative embodiment of the electromagnetic water tunnel device of the present invention, the electromagnetic water tunnel device includes a base 100 , a water channel 200 is opened on the base 100 , and water flows in the water channel 200 ; a section of the water channel 200 is a power section 201 .

[0045] In some embodiments, the electromagnetic water tunnel device includes two electrode plates 300, which are respectively located on two side walls of the power section 201; an electric field is formed between the two motor plates.

[0046] In some embodiments, the electromagnetic water tunnel device includes a magnetic member 400 , which is disposed above the power section 201 ; the magnetic field of the magnetic member 400 is perpendicular to the line connecting the two electrode plates 300 .

[0047] In some embodiments, the electromagnetic water tunnel device includes an ion replenishing device 500, which is used to replenish ions to the water in the water channel 200. The water in the power section 201 is charged by the electrode plate 300, and the magnetic field of the magnetic member 400 interacts with the charged water flow to form a Lorentz force to achieve the movement of the water flow.

[0048] Through the above scheme, a water channel 200 is opened on the base 100 and water circulates therein, providing a basic water flow environment for the entire electromagnetic water tunnel experiment; the setting of the power section 201 is conducive to focusing the interaction area of ​​electric energy, magnetic energy and water flow, and the two electrode plates 300 form an electric field on the side wall of the power section 201, which can charge the water flow, and cooperate with the upper magnetic member 400 to generate a magnetic field perpendicular to the line connecting the electrode plates 300. The two interact to generate Lorentz force, accurately driving the water flow to move; the ion replenishment device 500 can maintain the ion concentration of the water in the water channel 200, ensure the stability of the electric field effect, avoid poor charging effect due to ion consumption, and ensure that the electromagnetic water tunnel water flow power is continuous and stable. It can achieve high-precision speed control, flow field optimization and long-term stable operation.

[0049] In some embodiments, the base 100 can be the ground or any other structure, which can be selected according to the experimental site.

[0050] In some embodiments, the water channel 200 is a complete loop. The water channel 200 is a complete loop, and the water can circulate, without the need for continuous large-scale water replenishment, saving water resources; the circulating water flow is convenient for stable control of parameters such as water temperature and ion concentration, reducing interference from external factors, and is conducive to maintaining a stable experimental environment, creating conditions for long-term, multi-batch experiments, and reducing experimental costs and operational difficulties.

[0051] In some embodiments, the water channel 200 is annular. The water channel 200 is designed to be annular, making full use of the advantages of the annular structure. When the water flows in the annular water channel 200, the force is more uniform, there are no obvious corners or dead water areas, and the energy loss and turbulence caused by water flow impact and stagnation are avoided; the annular layout is compact, which is conducive to reducing the overall footprint of the device, optimizing space utilization, and meeting the needs of laboratory equipment integration.

[0052] Further, the water channel 200 includes two horizontal sections and two curved sections. The two horizontal sections are parallel to each other, and the two curved sections are semicircular, and the radius of the two curved sections is the same. The two curved sections are respectively located at the two ends of the length direction of the two horizontal sections, and the centers of the two curved sections are arranged oppositely, and the two ends of the curved sections are respectively connected to the ends of the two horizontal sections. This water channel 200 structure consisting of two horizontal sections and two curved sections of specific shapes allows the water flow to transition smoothly and regularly during the circulation process. The semicircular curved section can effectively reduce the turbulence generated when the water flow turns, and ensure that the water flow can still maintain a relatively stable flow state when passing through the bend and entering the horizontal section. The two horizontal sections are parallel to each other and the regular connection of the curved sections makes the water flow in the entire water channel 200 uniformly stressed, and the flow velocity distribution is easier to predict and control, providing a stable and uniform water flow foundation for different functional sections (such as the power section 201 and the test section 202) in the electromagnetic water tunnel device, which is conducive to accurately carrying out various experiments and obtaining reliable experimental data.

[0053] In some embodiments, the width of any cross section in the water channel 200 is the same. Keeping the width of any cross section in the water channel 200 the same can ensure that the water flow will not experience sudden changes in flow velocity, excessive local pressure difference, etc. due to changes in the width of the channel during the flow of the entire water channel 200, avoid unnecessary turbulence and vortices, and make the flow velocity, flow rate and other parameters of the water flow remain relatively stable and uniform at all positions, greatly improving the stability of the experimental environment, facilitating accurate analysis of various characteristics of the water flow under electromagnetic action, and helping to improve the repeatability of the experiment. No matter where the test is conducted or related research is carried out, the water flow state faced is relatively consistent.

[0054] In some embodiments, the power section 201 is in one of the horizontal sections. The power section 201 is arranged in the horizontal section, and the horizontal water flow path helps to better achieve the stable electric field effect between the electrode plate 300 and the charged water flow, reduce the interference of the electric field uniformity due to factors such as water flow inclination and turbulence, so that the electric energy can be more efficiently and evenly transmitted to the water flow, and then more accurately drive the water flow to move through the Lorentz force. At the same time, the structure of the horizontal section is convenient for arranging the electrode plate 300 and other related components, which is convenient for installation, commissioning and subsequent maintenance work, and is also conducive to accurate monitoring and analysis of various parameters of the water flow in the power section 201 (such as charging status, flow rate changes, etc.).

[0055] In some embodiments, a section of the waterway 200 is a test section 202; a detection device is provided at the test section 202. The object to be tested is tested in the test section 202. The test section 202 is provided with a detection device, and various physical parameters of the object to be tested in the test section 202, such as flow rate, pressure, flow state change, etc., can be measured in real time and accurately, which is conducive to scientific researchers to intuitively obtain experimental data and effectively improve research efficiency and accuracy of results.

[0056] In some embodiments, the test section 202 is in another horizontal section. By setting the test section 202 in another horizontal section, the characteristics of the relatively stable water flow, uniform flow velocity and flow state in the horizontal section can be fully utilized to provide an ideal test environment for the detection device, so that the detected data can more truly reflect the actual state of the water flow after the electromagnetic drive of the power section 201. In addition, the horizontal section is convenient for installing various test instruments, and sensors of different angles and types can be arranged more conveniently, so as to perform all-round and high-precision measurements on various physical quantities such as pressure, flow velocity, flow state, etc. of the water flow, which helps to improve the accuracy and reliability of the experimental results.

[0057] In some embodiments, two oppositely disposed guide plates 600 are disposed in the test section 202; the two ends of the two guide plates 600 are far from each other and the middle is close to each other. Because of the shape of the guide plates 600, three parts of contraction, straight line, and expansion are formed between the two guide plates 600, which are used to perform various hydrodynamic experiments. This design can simulate complex water flow conditions in real environments.

[0058] In some embodiments, the guide plate 600 is detachably connected to the test section 202 and can be manually removed, replaced or adjusted.

[0059] In some embodiments, the guide plate 600 includes a contraction section 601, a parallel section 602, and an expansion section 603. The contraction section 601, the parallel section 602, and the expansion section 603 are connected in sequence, wherein the contraction section 601 is close to the input direction of the water flow, and the expansion section 603 is close to the output direction of the water flow. The guide plate 600, which is composed of the contraction section 601, the parallel section 602, and the expansion section 603, can initially gather the water flow entering the test section 202 in the contraction section 601, so that the water flow velocity gradually increases and the flow direction becomes more concentrated, thereby reducing the dispersion and turbulence of the water flow; the parallel section 602 can keep the water flow after the initial regularization at a stable velocity and flow direction, forming a uniform flow layer; and the expansion section 603 can make the water flow spread smoothly when it flows out of the guide plate 600. According to the needs of the experiment, the experimental object can be placed at different positions between the two guide plates 600.

[0060] In some embodiments, the contraction section 601 is inclined from the direction toward the parallel section 602 to the direction toward another guide plate 600. The inclined setting of the contraction section 601 can gradually squeeze and guide the water flow along the water flow direction, so that the water flow begins to converge toward the middle when entering the guide plate 600, thereby strengthening the convergence effect of the water flow and prompting the water flow from different positions to be more evenly concentrated toward the middle, so as to increase the flow rate of the water flow entering between the parallel sections 602.

[0061] In some embodiments, the expansion section 603 is inclined from the direction away from the parallel section 602 to the direction away from the other guide plate 600. This inclined setting of the expansion section 603 allows the water flow to diffuse outwards smoothly and orderly along the inclined direction after flowing out of the parallel section 602, avoiding the water flow directly impacting the side wall of the water channel 200 to cause adverse phenomena such as backflow and turbulence, and can better restore the water flow to a state that is compatible with the overall flow state of the water channel 200, while maintaining a uniform change in flow velocity, reducing energy loss and water flow turbulence caused by sudden changes in flow velocity, ensuring that the water flow at the outlet of the test section 202 is still in a relatively stable state, maintaining the stability of the water flow environment of the entire test section 202, and improving the credibility of the experimental results.

[0062] In some embodiments, the two parallel sections 602 are parallel to each other and are vertically arranged in the width direction. The distances between the two parallel sections 602 and the corresponding adjacent side walls of the waterway 200 are the same.

[0063] In some embodiments, a rectifying grid 700 is provided at the entrance of the test section 202. The rectifying grid 700 is provided at the entrance of the test section 202, so as to sort out the chaotic water flow in advance, eliminate the interference factors caused by the uneven upstream water flow, vortex, etc., and sort out the water flow entering the test section 202 into a uniform, stable and parallel flow state, so as to create ideal conditions for subsequent precise testing, reduce the influence of the difference in the initial state of the water flow on the test results, and improve the comparability of experimental data.

[0064] In some embodiments, the rectifying grid 700 includes a plurality of mutually parallel rectifying plates, and the length direction of the rectifying plates is parallel to the test section 202. The rectifying grid 700 uses a plurality of mutually parallel rectifying plates, and its length direction is parallel to the test section 202. This structure maximizes the rectifying effect, intercepts and corrects the deviation of the water flow direction in all directions, and effectively eliminates the lateral turbulence of the water flow, further refines the water flow rectifying effect, ensures that the water flow entering the test section 202 has a uniform flow velocity and a consistent flow direction in each cross section, and improves the test accuracy.

[0065] Furthermore, the spacing between any two adjacent rectifier plates is the same, thereby ensuring that the water flow can be evenly divided and guided, and ensuring that the flow velocity is even and the flow direction is consistent.

[0066] Furthermore, the spacing between the rectifying plates is the same as the spacing between the rectifying plates at the end close to the corresponding side walls of the water channel 200, thereby ensuring that the water flow can be evenly divided and guided, and ensuring that the flow velocity is even and the flow direction is consistent.

[0067] In some embodiments, the magnetic member 400 is an electromagnet. The use of an electromagnet as the magnetic member 400 has significant advantages. The strength of the electromagnet magnetic field can be flexibly controlled by adjusting the current, which is convenient for researchers to accurately adjust the magnetic field strength according to different experimental conditions and water flow characteristics, and adapt the charged water flow to the required flow rate. The flexibility and adaptability of the electromagnetic water tunnel to water flow driving and regulation are enhanced, and the scope of application of the device is broadened.

[0068] In some embodiments, the axis around which the electromagnet coil is wound is perpendicular to the line between the two electrode plates 300, and is also perpendicular to the length direction of the corresponding horizontal segment. Setting the axis around which the electromagnet coil is wound in this way can ensure that the direction of the magnetic field generated by it forms an optimal spatial layout relationship with the direction of the electric field formed by the electrode plates 300 and the flow direction of the water flow in the horizontal segment. The direction of the magnetic field perpendicular to the line connecting the electrode plates 300, combined with the charging effect of the electric field on the water flow, can accurately and efficiently generate the Lorentz force to drive the water flow to move according to the principle of electromagnetic induction, so that the direction of the Lorentz force is well matched with the direction of the water flow, avoiding the decomposition or cancellation of the force due to the deviation of the magnetic field direction, and maximizing the effect of electromagnetic driving the water flow. At the same time, the magnetic field layout perpendicular to the length direction of the horizontal section can ensure that the magnetic field is evenly distributed throughout the entire horizontal section and acts stably on the water flow, so that the electromagnetic driving force exerted on the water flow at different positions is relatively consistent, further ensuring the stability and uniformity of the water flow state, and helping to create a stable and predictable water flow environment in the entire power section 201 and the subsequent test section 202, thereby improving the accuracy of the experimental data and the reliability and controllability of the operation of the entire electromagnetic water tunnel device.

[0069] In some embodiments, the electrode plate 300 is made of graphite. The electrode plate 300 is made of graphite, which has excellent conductivity and can efficiently transfer electrical energy to the water flow, so that the water flow is quickly and evenly charged; at the same time, graphite has stable chemical properties and strong water corrosion resistance. It is not easy to chemically react and wear the electrode plate 300 when immersed in water for a long time, ensuring the service life of the electrode plate 300, maintaining the stability of the electric field, and ensuring the continuous and stable operation of the electromagnetic water tunnel.

[0070] In some embodiments, a hydrogen and oxygen removal device 800 is provided at the power section 201. The power section 201 is provided with a hydrogen and oxygen removal device 800. During the experiment, water electrolysis will produce hydrogen and oxygen, which may form bubbles after accumulation, interfere with the water flow, change the fluid density, and destroy the experimental stability. The device can remove hydrogen and oxygen gases in time, prevent bubble aggregation, maintain the purity of the water flow and the stability of the flow state, ensure that the experimental data is not interfered by the gas, and improve the credibility of the experimental results. In addition, hydrogen and oxygen are easily explosive when mixed, and they are removed by the hydrogen and oxygen removal device 800 to avoid explosion and ensure safety.

[0071] In some embodiments, the hydrogen and oxygen removal device 800 includes gas collection, gas separation and gas discharge structures. The gas collection structure includes an air chamber and a gas collection pipeline. The air chamber is often placed at the top of the waterway 200 where gas is easily gathered to guide the dispersed gas.

[0072] Furthermore, the gas separation structure can adopt diaphragm separation or adsorption separation, using metal organic framework materials to screen and adsorb hydrogen and oxygen according to conditions; the gas exhaust structure is provided with an exhaust pipe connected to the gas chamber, which is equipped with a valve to regulate the exhaust speed and flow rate. Some devices with high safety requirements will also be connected to ventilation equipment to discharge the separated hydrogen and oxygen to the outside to prevent gas accumulation.

[0073] In some embodiments, the ion replenishment device 500 is mainly composed of a storage unit, a delivery system and a control unit.

[0074] In some embodiments, the storage unit of the ion replenishment device 500 uses solution storage, and stores a solution containing specific ions in a sealed container.

[0075] In some embodiments, the storage unit of the ion replenishment device 500 is stored in ion exchange resin, which is filled with resin. Water flows through the storage unit to exchange ions with the resin to achieve ion replenishment. In some embodiments, the delivery system of the ion replenishment device 500 is powered by a pump to ensure that the liquid flows stably and continuously in the pipeline to meet the experimental requirements.

[0076] In some embodiments, the control unit of the ion replenishment device 500 is equipped with a sensor to monitor the ion concentration of the target system in real time. Once the concentration is lower than the set value, the ion replenishment program is immediately driven to accurately control the timing and dosage of ion replenishment to ensure that the entire device operates stably according to preset parameters and adapts to various usage scenarios.

[0077] In some embodiments, the electromagnetic water tunnel device also includes a power supply, which supplies power to devices in the electromagnetic water tunnel that require power.
