Description

Technical Field

[0001] This invention belongs to the field of thermal engine technology, and particularly relates to a built-in magnetic monopole thermal power device. Background Technology

[0002] A thermomagnetic engine is a device that uses the change in magnetic conductivity of a metallic material near the Curie point to achieve power output. Compared with another type of thermal engine, the Stirling engine, it has the advantages of simple structure, no working fluid consumption, low noise, low cost and long life.

[0003] Thermomagnetic propulsion technology is commonly used in temperature control switching circuits, but its engineering applications in the engine field are relatively limited. Currently, thermomagnetic engines mainly employ two technologies. One method utilizes the abrupt change in the magnetic permeability of a magnetic material around its Curie point to achieve power output. This approach results in a step-like power output, poor adaptability to temperature changes, and difficulty in achieving continuous and stable power output. The other method utilizes the continuous change in the magnetic permeability of a magnetic material below its Curie point with temperature changes to achieve power output. This technology can adapt to temperature changes better and theoretically can continuously output stable power. However, due to limitations in the design of the magnetic field's spatial structure, existing thermomagnetic engine prototypes still suffer from problems such as low power output, unstable motion (even experiencing reversal during motion), and inability to operate continuously. Summary of the Invention

[0004] The purpose of this invention is to provide a built-in magnetic monopole thermodynamic device to solve the above-mentioned problems and provide a thermomagnetic motor with more stable and reliable power output.

[0005] To achieve the above objectives, the present invention provides the following solution: a built-in magnetic monopole thermodynamic device, comprising:

[0006] Heating element;

[0007] The rotor rotates in conjunction with the heating element. Working material is formed on the working surface of the rotor. The working material passes through the heating element as the rotor rotates to form a heated end with a temperature difference.

[0008] A working body is disposed inside the rotor and separated from the heating body by the rotor. A magnetic field is formed between the working body and the rotor. Under the action of the magnetic field, the working material drives the rotor to rotate in the rotation direction based on the temperature difference.

[0009] A magnetic field blocking element is configured to block the action of the magnetic field relative to the working body.

[0010] Preferably, the working body includes a permanent magnet, which is configured such that the magnetic field strength generated on the working material gradually decreases from the center to both ends of the permanent magnet, and there is an adjustable angle between the permanent magnet and the heated end;

[0011] The permanent magnet, based on the included angle, can rotate in a direction opposite to the rotation direction without losing the magnetic field effect on the heated end.

[0012] Preferably, the permanent magnet has a magnetic pole on the side near the heated end, and the magnetic pole has an arc-shaped structure.

[0013] Preferably, the working body further includes:

[0014] An adjusting frame is rotatably fitted inside the rotor. The center of the adjusting frame is fixed with the middle part of an adjusting shaft. One end of the adjusting shaft extends out of the rotor and is connected to the adjusting valve through a transmission mechanism. The adjusting frame can be adjusted to rotate relative to the heated end through the adjusting valve.

[0015] Preferably, the adjustment frame is a triangular frame structure, and the outer periphery of the adjustment frame is configured to make rolling contact with the rotor via rollers.

[0016] Preferably, the magnetic field blocking component includes a plurality of stacked and fixed magnetic pole baffles, the side of the permanent magnet away from the heated end is fixed to the outermost magnetic pole baffle, and the projected area of ​​this side perpendicular to the magnetic pole baffle is smaller than the end face area of ​​the adjacent magnetic pole baffle.

[0017] Preferred options also include:

[0018] The first bracket and the second bracket are arranged opposite to each other on both sides of the rotor. The two ends of the adjusting shaft extend relative to the rotor and are rotatably connected to the first bracket and the second bracket respectively. The adjusting valve is disposed on the first bracket or the second bracket.

[0019] A drive shaft is arranged on one side of the rotor, the drive shaft is configured to rotate through the rotor in the rotation direction and is rotatably connected to the adjustment shaft.

[0020] Preferably, the rotor has a hollow cylindrical structure;

[0021] The heating element is a heating cylinder, and the heating cylinder has an opening at one end near the rotor. The rotor is heated by passing through the opening of the heating cylinder during rotation.

[0022] Preferably, the working material includes a plurality of soft magnetic alloy materials, which are arranged axially at equal intervals on the outer periphery of the rotor.

[0023] Preferably, the heating element is fixed relative to the ground.

[0024] Compared with the prior art, the present invention has the following advantages and technical effects:

[0025] This invention heats the working material using a heating element. Since the working material is positioned on the working surface of the rotor, the rotational cooperation between the rotor and the heating element creates a temperature difference at the heated end of the working material during heating. Utilizing the Curie point characteristic, the magnetic field generated by the working element, through this temperature difference, forms a changing magnetic force. This magnetic force continuously provides the force to rotate the rotor in the direction of rotation, maintaining continuous power output. Furthermore, the working element, which generates the magnetic field, is located inside the rotor. Separated from the heating element by the rotor, this effectively mitigates the reduction in magnetic field effect caused by the heating of the working element itself, ensuring the driving stability of the thermomagnetic motor. Additionally, by placing the working material on the working surface of the rotor and extending and supporting it, this improves the efficiency of heat absorption and release at the heated end of the working material, thereby enhancing the overall power output of the thermomagnetic motor.

[0032] 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.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example: Refer to Figures 1-4 A built-in magnetic monopole thermodynamic device, comprising:

[0035] Heating element;

[0036] Rotor 1 rotates in conjunction with heating element. Working material is formed on the working surface of rotor 1. The working material passes through heating element as rotor 1 rotates to form a heated end with a temperature difference.

[0037] The working body is set inside the rotor 1 and separated from the heating body by the rotor 1. A magnetic field is formed between the working body and the rotor 1. Under the action of the magnetic field, the working material drives the rotor 1 to rotate in the rotation direction based on the temperature difference.

[0038] A magnetic field blocking element is configured to block the action of a magnetic field relative to the working body.

[0039] This invention heats the working material using a heating element. Since the working material is positioned on the working surface of rotor 1, the rotational interaction between rotor 1 and the heating element creates a temperature difference at the heated end of the working material during heating. Due to the Curie point characteristic, the magnetic field generated by the heating element acts on the working material, varying with the temperature difference. The magnetic field strength is lower in higher-temperature regions than in lower-temperature regions. Therefore, as rotor 1 rotates, the heating element continuously heats the working material at the heated end, causing the magnetic field strength acting on the working material to decrease along the rotation direction of rotor 1. The rear side gradually decreases towards the heated end, thereby providing a force that causes the rotor 1 to rotate in the direction of rotation. The working body that generates a magnetic field is set inside the rotor 1. By separating the rotor 1 from the heating body, the magnetic field effect generated by the working body itself is effectively mitigated due to the heating effect. At the same time, the magnetic field blocking component can block the magnetic field effect released along the direction of the working body, ensuring the driving stability of the thermomagnetic motor. Furthermore, this technical solution places the working material on the working surface of the rotor 1, and the rotor 1 extends and supports the working material, improving the efficiency of heat absorption and release of the working material at the heated end, thereby improving the overall power output of the thermomagnetic motor.

[0040] Furthermore, the working body includes a permanent magnet 4, which is configured such that the magnetic field strength generated on the working material gradually decreases from the center to both ends of the permanent magnet 4, and there is an adjustable angle between the permanent magnet 4 and the heated end.

[0041] Based on the existing angle, the permanent magnet 4 can rotate in the opposite direction to the rotation direction without losing the magnetic field effect on the heated end.

[0042] Furthermore, a magnetic pole 10 is formed on the side of the permanent magnet 4 near the heated end, and the magnetic pole 10 has an arc-shaped structure.

[0043] Reference Figure 2 , Figure 3 When the magnetic force acts on the heated end, the permanent magnet 4 rotates in the opposite direction to the rotation direction of the rotor 1 to adjust the angle, creating an asymmetrical distribution of the magnetic force relative to the working material at the heated end. This ensures that the magnetic force acting on the working material at the rear end of the rotor 1's rotation is greater than the magnetic force acting on the front end of the rotor 1's rotation, achieving an eddy current assist effect on the rotor 1 along the rotation direction, thus ensuring the stability of the power output. Furthermore, by setting the magnetic pole 10 formed on the side of the permanent magnet 4 near the heated end as an arc-shaped structure, the magnetic field strength released by the permanent magnet 4 relative to the heated end gradually decreases from the center to both ends of the arc-shaped end face. After an angle is established between the permanent magnet 4 and the heated end, refer to... Figure 4 The magnetic force can be applied more effectively to the lag end of rotor 1, thereby effectively increasing the rotational torque of rotor 1 and improving the power output.

[0044] It is understandable that this patent adopts a single permanent magnet 4 structure, which can effectively prevent the magnetic field force released by the permanent magnet 4 from generating eddy current effects between other moving magnetic conductors in the rotor 1, further ensuring the stability of power output.

[0045] Furthermore, the working body also includes:

[0046] The adjusting frame 2 is rotatably fitted inside the rotor 1. The center of the adjusting frame 2 is fixed with the middle part of the adjusting shaft 3. One end of the adjusting shaft 3 extends out of the rotor 1 and is connected to the adjusting valve 13 through a transmission mechanism. The adjusting frame 2 can rotate in an adjustable manner relative to the heated end through the adjusting valve 13.

[0047] In this technical solution, the magnetic field blocking component is preferably, but not limited to, made of a magnetic shielding material. The permanent magnet 4 is fixed to the side of the adjusting frame 2 near the heated end using the magnetic field blocking component. The transmission mechanism is a common worm gear or bevel gear meshing transmission structure, refer to... Figure 1A worm gear (not shown in the figure) is fixedly connected to one end of the second bracket 12 that extends vertically along the regulating valve 13. A worm wheel meshes with the worm gear, and the axis of the worm wheel is fixedly connected to any end of the regulating shaft 3. This allows the regulating frame 2 to be rotated by rotating the regulating valve 13, thereby driving the permanent magnet 4 to rotate relative to the heated end to adjust the angle. At the same time, the magnetic field blocking component can effectively block the magnetic field force released by the permanent magnet 4 along the direction of the regulating frame 2, thereby increasing the magnetic field strength output by the magnetic pole 10 to the heated end side and improving the power of the eddy current effect generated by the magnetic transmission.

[0048] In one embodiment of the present invention, the regulating valve 13 controls the regulating frame 2 to drive the permanent magnet 4 to deflect relative to the rotor 1 at an angle, such as... Figure 2 As shown, when the central axis of the permanent magnet 4 is perpendicular to the heated end, the magnetic force is evenly distributed and loses the effect of generating eddy currents in the opposite direction on the rotor 1. At this time, the rotor 1 does not rotate to do work. However, when starting the rotor 1, it is only necessary to adjust the valve 13 to drive the adjusting frame 2 to rotate relative to the rotor 1 in any direction, which can generate the effect of transmitting power in the opposite direction of the rotor 1, thereby improving the ease of use of the overall power device.

[0049] Furthermore, the adjusting frame 2 has a triangular frame structure, and its outer periphery is configured to roll in contact with the rotor 1 via rollers. A slot is provided at the center of the adjusting frame 2, and a pin structure is integrally formed on the adjusting shaft 3. The pin structure engages with the slot for secure installation, facilitating the installation and removal of the adjusting shaft 3 and the adjusting frame 2.

[0050] By sequentially fixing several magnetic pole baffles 5 to one side of the adjusting frame 2, and by having the rollers on the adjusting frame 2 roll into contact with the rotor 1, the stability of the output power generated by the rotation of the rotor 1 is ensured. Correspondingly, the rotor 1 preferably adopts a circular structure that is adapted to the rotation trajectory of the outside of the tripod, thereby improving the transmission stability generated after the rotor 1 rolls into contact with the rollers on the tripod.

[0051] Furthermore, the magnetic field barrier includes several stacked and fixed magnetic pole baffles 5. The side of the permanent magnet 4 away from the heated end is fixed to the outermost magnetic pole baffle 5, and the projected area of ​​this side perpendicular to the magnetic pole baffle 5 is smaller than the end face area of ​​the adjacent magnetic pole baffle 5.

[0052] Reference Figure 4 The projection of the end face of the permanent magnet 4 near the magnetic pole baffle 5 is smaller than the end face area of ​​the adjacent magnetic pole baffle 5, which improves the effect of the magnetic pole baffle 5 in blocking the magnetic field force. Furthermore, based on the arc-shaped structure of the magnetic pole 10, the magnetic field force released along the edge of the arc-shaped end face can be blocked by the edge of the magnetic pole baffle 5 due to the direction of the magnetic field lines, further enhancing the blocking effect between the other magnetic conductors in the rotor 1.

[0053] Furthermore, it also includes:

[0054] The first support 11 and the second support 12 are arranged opposite to each other on both sides of the rotor 1. The two ends of the adjusting shaft 3 extend relative to the rotor 1 and are rotatably connected to the first support 11 and the second support 12 respectively. The adjusting valve 13 is set on the first support 11 or the second support 12.

[0055] The drive shaft 7 is arranged on one side of the rotor 1. The drive shaft 7 is configured to rotate through the rotor 1 in the rotation direction and is rotatably connected to the adjusting shaft 3.

[0056] Reference Figure 1 By arranging the first bracket 11 and the second bracket 12 on both sides of the rotor 1 respectively, the transmission shaft 7 is fixedly connected to the rotor 1, and a bearing 8 is provided in the transmission shaft 7. The end of the adjusting shaft 3 extending out of the rotor 1 is inserted into the bearing 8 to realize the rotational connection between the adjusting shaft 3 and the transmission shaft 7. The first bracket 11 and the second bracket 12 are fixed to the ground to enhance the stability during the power transmission process.

[0057] Furthermore, rotor 1 has a hollow cylindrical structure;

[0058] The heating element is a heating cylinder 6. The heating cylinder 6 has an opening at one end near the rotor 1. The outer periphery of the rotor 1 flows through the heating cylinder 6 and rotates within the opening.

[0059] In this technical solution, the rotor adopts a hollow cylindrical rotor 1 structure. An opening is made on the heating cylinder 6 so that the rotor 1 is rotated and engaged in the opening through the first support 11 and the second support 12. When the permanent magnet 4 and the working material cooperate to form an eddy current effect that drives the rotor 1 to rotate, the part of the rotor 1 located in the opening has an arc-shaped structure, which effectively increases the amount of working material at the heated end and the heat absorption and release effect.

[0060] Furthermore, the working material includes several soft magnetic alloy materials 9, which are axially and equally spaced on the outer periphery of the rotor 1.

[0061] By setting several soft magnetic alloy materials 9 into a strip structure and arranging them along the axis of the rotor 1, the soft magnetic alloy materials 9 pass through the heating cylinder 6 in sequence during the rotation of the rotor 1. The heating cylinder 6 heats the soft magnetic alloy materials 9. After the soft magnetic alloy materials 9 are heated, the magnetic force generated between them and the permanent magnet 4 is reduced through Curie point thermal properties. At the same time, the magnetic force at the rear end of the rotation direction remains unchanged (or increases). As a result, the magnetic force of the permanent magnet 4 gradually decreases from the rear end of the rotor 1 to the front end, thereby forming an eddy current effect that drives the rotor 1.

[0062] Furthermore, the heating element is fixed relative to the ground.

[0063] The working process of this embodiment is as follows:

[0064] After determining the required rotation direction of rotor 1, the adjusting frame 2 is rotated by adjusting valve 13, and the permanent magnet 4 is rotated in the opposite direction to the rotation direction of rotor 1. This creates a certain angle between the permanent magnet 4 and the heating cylinder 6, ensuring that the magnetic field does not leave the heated end. After heating gas is introduced into the heating cylinder 6 to heat the soft magnetic alloy material 9, the attraction between the soft magnetic alloy material 9 and the permanent magnet 4 decreases. At the same time, the attraction between the permanent magnet 4 and the soft magnetic alloy material 9 outside the heated end remains unchanged, thereby generating an eddy current effect rotating in the rotation direction. This eddy current effect is applied to rotor 1 through the soft magnetic alloy material 9. When the soft magnetic alloy material 9 at room temperature is attracted into the heated end and heated, the soft magnetic alloy material 9 in the original heated end leaves the heating cylinder 6 and decreases. By repeating the above steps, rotor 1 is driven to rotate. The rotation torque of rotor 1 is effectively improved by the set single-pole permanent magnet 4 and the asymmetrically distributed magnetic field force formed by the permanent magnet 4, realizing the efficient transmission of the driving force of the thermomagnetic motor.
