Among them, permanent magnet eddy current heating has become an industry focus due to its efficiency potential.
[0003] Existing permanent magnet eddy current heating devices have a single permanent magnet arrangement method, and most of them do not adopt an optimized magnetic field enhancement structure. The magnetic field utilization rate is not high, resulting in insufficient magnetic field strength at the air gap. Consequently, the eddy current intensity induced by the conductor disk is limited, the heating efficiency is low, and it is impossible to provide the required heat energy quickly and in sufficient quantity.

Detailed Implementation
[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.
[0020] Existing permanent magnet eddy current heating devices employ a single arrangement of permanent magnets, often lacking optimized magnetic field enhancement structures. This results in low magnetic field utilization, insufficient magnetic field strength at the air gap, and consequently, limited eddy current intensity induced in the conductor disk, leading to low heating efficiency and an inability to quickly and adequately provide the required heat energy. The permanent magnet eddy current wind-powered heating device provided in this application uses a wind-driven mechanism to drive a transmission mechanism that rotates the permanent magnet rotor relative to the conductor disk. The permanent magnet rotor generates a periodically changing magnetic field, inducing eddy currents in the conductor disk and converting them into heat energy. Furthermore, the permanent magnet rotor's magnetic ring assembly employs a Halbach array design, which enhances the magnetic field strength at the air gap, thereby improving energy conversion efficiency.
[0021] The specific structure and working process of the permanent magnet eddy current wind-powered heating device provided in this application will be described in detail below with reference to the accompanying drawings.
[0022] Reference Figures 1-7 As shown, this application provides a permanent magnet eddy current wind-powered heating device, including a wind-driven mechanism 100, a transmission mechanism 200, and a heating mechanism 300; the heating mechanism 300 includes a housing 310, a permanent magnet rotor 320, and a conductor disk 330. The pneumatic mechanism 100 is mounted on the housing 310; the transmission mechanism 200 is rotatably connected to the housing 310; the permanent magnet rotor 320 is mounted on the transmission mechanism 200 and located inside the housing 310; the conductor disk 330 is fixed inside the housing 310 and located below the permanent magnet rotor 320; an air gap is formed between the conductor disk 330 and the permanent magnet rotor 320. The pneumatic mechanism 100 is driven to connect with the transmission mechanism 200 and is used to drive the transmission mechanism 200 to rotate relative to the conductor disk 330. The permanent magnet rotor 320 is used to generate a periodically changing magnetic field when rotating with the transmission mechanism 200. The conductor disk 330 is used to induce eddy currents under the action of the magnetic field and convert them into heat energy. The permanent magnet rotor 320 includes a support ring 321 and a magnetic ring assembly disposed on the support ring 321. The magnetic ring assembly includes permanent magnets and non-magnetic blocks 325, which are arranged in a Halbach array. The magnetic ring assembly is used to enhance the strength of the magnetic field at the air gap.
[0023] like Figures 1-3 As shown, the core components of the permanent magnet eddy current wind-powered heating device provided in this application include a wind-driven mechanism 100, a transmission mechanism 200, and a heating mechanism 300. The wind-driven mechanism 100 is disposed on the heating mechanism 300. The output end of the wind-driven mechanism 100 is connected to one end of the transmission mechanism 200, and the other end of the transmission mechanism 200 is connected to the heating mechanism 300.
[0024] The heating mechanism 300 includes a housing 310, a permanent magnet rotor 320, and a conductor disk 330. The housing 310 may be made of high-strength stainless steel, and its interior forms a sealed cavity to protect the permanent magnet rotor 320, conductor disk 330, and other components, preventing external impurities from entering and affecting the operation of the device. The permanent magnet rotor 320 may be a ring structure, fixedly sleeved on the transmission mechanism 200, and rotates synchronously with the transmission mechanism 200; the conductor disk 330 is a circular metal disk made of a high-conductivity material, fixedly installed inside the housing 310, and parallel to the permanent magnet rotor 320 below it, with a certain air gap between the two to avoid direct contact.
[0025] The wind-driven mechanism 100 is mounted on the top of the housing 310. The core function of the wind-driven mechanism 100 is to capture wind energy and convert it into mechanical power to drive the transmission mechanism 200 to rotate stably relative to the housing 310 and the conductor disk 330.
[0026] When the transmission mechanism 200 rotates, it drives the permanent magnet rotor 320 to rotate together. During the rotation, the permanent magnet rotor 320 generates a periodically changing magnetic field. The stationary conductor disk 330 is in this changing magnetic field and generates eddy currents due to electromagnetic induction. When the eddy currents move inside the conductor disk 330, they convert electrical energy into heat energy, ultimately realizing the wind-powered heating function.
[0027] Compared to existing technologies where the permanent magnet and conductor disk are in direct contact, this device employs a non-contact design where the permanent magnet rotor 320 rotates and the conductor disk 330 is fixed. Combined with the air gap between them, this fundamentally eliminates mechanical friction between the permanent magnet rotor 320 and the conductor disk 330, reducing component wear and lowering maintenance costs associated with frequent component replacements. The absence of frictional loss allows more wind energy to be used to drive the permanent magnet rotor 320 to generate a magnetic field, improving energy conversion efficiency and enabling more efficient conversion of wind energy into heat energy, making it suitable for scenarios with high energy efficiency requirements. Under low wind speed conditions, the wind-driven mechanism 100 does not need to overcome frictional resistance; only a small amount of wind is required to drive the transmission mechanism 200 to rotate. This allows the device to start normally in environments with weak wind resources, effectively broadening the applicable wind conditions and improving environmental adaptability.
[0028] like Figure 3 As shown, the permanent magnet rotor 320 adopts a Halbach array design, which achieves magnetic field enhancement and direction optimization through precise magnet arrangement. The specific structure is as follows: The permanent magnet rotor 320 includes a support ring 321 and a magnetic ring assembly disposed on the support ring 321. The support ring 321 is an annular metal frame made of non-magnetic materials such as copper alloy or stainless steel. The inner end of the support ring 321 is connected to the transmission mechanism 200. A magnet mounting groove can be opened on the upper surface of the support ring 321 to provide a stable assembly reference for the Halbach array magnet. The magnetic ring assembly includes permanent magnets and non-magnetic blocks 325, which are arranged in a Halbach array. The magnetic ring assembly is used to enhance the strength of the magnetic field at the air gap, thereby improving the energy conversion efficiency.
[0029] Reference Figure 3 As shown, in some embodiments, the permanent magnet includes a first magnet 322, a second magnet 323, a third magnet 324, a fourth magnet 326, and a fifth magnet 327. The magnetic field directions of the first magnet 322 and the fourth magnet 326 are parallel to the axis of the support ring 321, while the magnetic field directions of the second magnet 323, the third magnet 324, and the fifth magnet 327 are perpendicular to the axis of the support ring 321. Multiple first magnets 322 and multiple second magnets 323 are arranged in a ring and alternate around the axis of the bearing ring 321 to form a first magnetic ring. The magnetic fields of the two first magnets 322 located on both sides of the second magnets 323 are opposite in direction, and the magnetic fields of the two second magnets 323 located on both sides of the first magnets 322 are opposite in direction. Multiple third magnets 324 and multiple non-magnetic blocks 325 are arranged in a ring-like alternating pattern around the axis of the bearing ring 321 to form a second magnetic ring; Multiple fourth magnets 326 and multiple fifth magnets 327 are arranged in a ring and alternate around the axis of the bearing ring 321 to form a third magnetic ring. The magnetic fields of the two fourth magnets 326 located on both sides of the fifth magnet 327 are opposite, and the magnetic fields of the two fifth magnets 327 located on both sides of the fourth magnet 326 are opposite. The first magnetic ring, the second magnetic ring, and the third magnetic ring are coaxially arranged from the inside to the outside along the axis of the bearing ring 321. Along the radial direction of the bearing ring 321, the first magnet 322, the third magnet 324, and the fourth magnet 326 are correspondingly arranged, and the second magnet 323, the non-magnetic block 325, and the fifth magnet 327 are correspondingly arranged. The magnetic field directions of the first magnet 322 and the fourth magnet 326 located in the same radial direction are opposite, and the magnetic field directions of the second magnet 323 and the fifth magnet 327 located in the same radial direction are opposite.
[0030] like Figure 3 As shown, the first magnetic ring includes a first magnet 322 with its magnetic field direction parallel to the axis of the support ring 321 and a second magnet 323 with its magnetic field direction perpendicular to the axis of the support ring 321. Multiple first magnets 322 and multiple second magnets 323 are arranged in a ring-like alternation around the axis of the support ring 321. This arrangement conforms to the core feature of the Halbach array that "the magnetic field direction of adjacent magnets differs by 90°". Furthermore, the magnetic field directions of two adjacent first magnets 322 along the circumferential direction are opposite, such as alternating upward and downward along the axis. The magnetic field directions of two adjacent second magnets 323 along the circumferential direction are opposite, such as alternating inward and outward along the radial direction. Through this alternation of directions, a magnetic field superposition effect is formed on the side of the first magnetic ring near the conductor disk 330.
[0031] The second magnetic ring includes a third magnet 324 and a non-magnetic block 325 with the magnetic field direction perpendicular to the axis of the support ring 321. Multiple third magnets 324 and multiple non-magnetic blocks 325 are arranged in a ring and alternate around the axis of the support ring 321. The non-magnetic blocks 325 are made of ceramic or plastic. Their function is to meet the magnetic field control requirements of the Halbach array, avoid mutual interference between the magnetic fields of adjacent magnets, and guide the magnetic field to concentrate on the target area conductor disk 330 side to reduce the back side magnetic field loss.
[0032] The third magnetic ring includes a fourth magnet 326 with its magnetic field direction parallel to the axis of the support ring 321 and a fifth magnet 327 with its magnetic field direction perpendicular to the axis of the support ring 321. Multiple fourth magnets 326 and multiple fifth magnets 327 are arranged in a ring-like alternating pattern around the axis of the support ring 321. The magnetic field directions of two adjacent fourth magnets 326 along the circumferential direction are opposite, and the magnetic field directions of two adjacent fifth magnets 327 along the circumferential direction are opposite. The third magnetic ring and the first magnetic ring form a "symmetrical Halbach subarray", which further enhances the magnetic field superposition effect. At the same time, the non-uniformity of the magnetic field distribution is eliminated through complementary directions.
[0033] Along the radial direction of the bearing ring 321, multiple first magnets 322 of the first magnetic ring, multiple third magnets 324 of the second magnetic ring, and multiple fourth magnets 326 of the third magnetic ring correspond one-to-one. Multiple second magnets 323 of the first magnetic ring, multiple non-magnetic blocks 325 of the second magnetic ring, and multiple fifth magnets 327 of the third magnetic ring also correspond one-to-one. The magnetic field directions of the radially corresponding first magnets 322 and fourth magnets 326 are opposite, and the magnetic field directions of the radially corresponding second magnets 323 and fifth magnets 327 are opposite. This radial correspondence is the key to the "multi-layer synergistic enhancement" of the Halbach array. Through the superposition and complementarity of magnetic fields of magnets in opposite directions at different levels, a high-intensity focused magnetic field is finally formed in the air gap region. Finally, a high-intensity and highly uniform focused magnetic field is formed in the air gap region between the permanent magnet rotor 320 and the conductor disk 330. At the same time, the magnetic field on the back side of the permanent magnet rotor 320 away from the conductor disk 330 is significantly weakened, reducing magnetic energy waste.
[0034] The permanent magnet rotor 320 provided in this application has the following advantages: Significantly enhanced magnetic field strength and greatly optimized thermal efficiency: Based on the core characteristics of the Halbach array—"magnetic field focusing and superposition"—this permanent magnet rotor 320 can generate a magnetic field strength in the air gap region opposite the conductor disk 330 that is far higher than that of traditional uniformly arranged magnets. When the stronger magnetic field acts on the conductor disk 330, it can induce stronger eddy currents, resulting in a more significant Joule heating effect. This directly improves the thermal energy output efficiency of the device, greatly increasing the heat power at the same wind speed, making it more suitable for high-heat demand scenarios such as working area heating and wellhead antifreeze.
[0035] Improved magnetic energy utilization and significantly reduced energy loss: The "back-side magnetic field weakening" characteristic of the Halbach array significantly weakens the magnetic field on the side of the permanent magnet rotor 320 away from the conductor disk 330, avoiding the meaningless diffusion and loss of the back-side magnetic field in traditional magnet arrangements. This design allows the magnetic energy generated by the permanent magnet to act more concentratedly on the air gap and conductor disk 330 in the target area, greatly improving the magnetic energy utilization rate. Higher magnetic field effects can be achieved without increasing the amount of permanent magnets, reducing the cost of permanent magnet materials and reducing energy waste caused by magnetic field diffusion, further optimizing the overall energy conversion efficiency.
[0036] Adaptable to low wind speed conditions, further expanding the scope of application: The strong magnetic field characteristics brought by the Halbach array enable the device to generate a sufficiently strong magnetic field even in low wind speed scenarios. Even if the connecting shaft 220 rotates at a low speed, the strong magnetic field can still induce eddy current heat energy to meet basic heating needs. Compared with the start-up wind speed of traditional magnet arrangement devices, the start-up wind speed is greatly reduced, further expanding the scope of application of the device in the working area and improving the device's adaptability to complex wind field environments.
[0037] Reference Figure 4 and Figure 5 As shown, in some embodiments, the conductor disk 330 is provided with a heat exchange channel 331, and the two ends of the heat exchange channel 331 are respectively provided with an inlet 332 and an outlet 333. The inlet 332 is connected to the external water supply pipeline, and the outlet 333 is connected to the external return water pipeline.
[0038] like Figure 4 and Figure 5 As shown, a heat exchange channel 331 is provided inside the conductor disk 330 to achieve efficient heat energy export.
[0039] The conductor disk 330 is a circular metal disk, and the heat exchange channel 331 inside is a continuous channel structure with smooth inner walls to reduce fluid resistance. The heat exchange channel 331 is provided with an inlet 332 and an outlet 333 at both ends, both of which are cylindrical interfaces with threads on the outer wall to facilitate connection with external pipelines.
[0040] The inlet 332 is connected to the external water supply pipeline, which can transport low-temperature heat exchange medium such as cold water. The medium enters the heat exchange channel 331 through the inlet 332. The outlet 333 is connected to the external return water pipeline. The high-temperature heat exchange medium that has absorbed heat energy flows into the return water pipeline through the outlet 333 and is then transported to heating, greenhouse and other heat-demanding scenarios to form a complete heat energy utilization cycle.
[0041] Furthermore, in some embodiments, the heat exchange channel 331 includes an extension section and a serpentine meandering section; The inlet 332 is one end of the extension section and is located in the edge region of the conductor disk 330. The other end of the extension section extends radially along the conductor disk 330 to the middle region of the conductor disk 330 and is connected to one end of the serpentine meandering section. The serpentine meandering section is centered on the axis of the conductor disk 330 and is distributed in a serpentine manner. The outlet 333 is the other end of the serpentine meandering section and extends to the edge area of the conductor disk 330.
[0042] The heat exchange channel 331 is divided into an extension section and a serpentine meandering section. Both sections are circular channels with the same diameter to ensure smooth fluid flow.
[0043] The inlet 332 is located at one end of the extension section, in the edge area of the conductor disk 330. This location facilitates connection with the external water supply pipeline and reduces pipeline bends. The other end of the extension section extends radially along the conductor disk 330 to the middle area and connects with one end of the serpentine meandering section, so that the heat exchange medium can be smoothly transported from the edge to the core heating area of the conductor disk 330.
[0044] The serpentine meandering section is centered on the axis of the conductor disk 330 and is distributed in a continuous "U" shape. This structure greatly increases the length and coverage area of the heat exchange channel 331 within the conductor disk 330. The outlet 333 is located at the other end of the serpentine meandering section and extends to the edge area of the conductor disk 330, corresponding to the position of the inlet 332, which facilitates connection with the external return water pipeline and ensures smooth circulation of the heat exchange medium.
[0045] The serpentine, meandering design increases the contact area and time between the heat exchange medium and the conductor disk 330, allowing the heat exchange medium to absorb heat energy more fully. This significantly improves heat exchange efficiency compared to a straight channel, reducing heat waste. The heat exchange channel 331 extends from the edge to the center and then meanders, covering the entire area of the conductor disk 330. This ensures that heat generated in all parts of the conductor disk 330 is absorbed evenly, preventing localized overheating or residual heat, further protecting the conductor disk 330 and extending its service life. The rational channel layout results in low flow resistance for the heat exchange medium, eliminating the need for additional power and reducing energy consumption during operation. It also facilitates channel fabrication and subsequent cleaning and maintenance, reducing overall operating costs.

The axis of the second screw hole is parallel to the end face of the conductor disk 330, and the adjusting screw 420 is screwed into the second screw hole. The circumferential surface of the conductor disk 330 is provided with a guide blind hole 334 that matches the adjusting screw sleeve 430. The extension direction of the guide blind hole 334 forms an angle with the end face of the conductor disk 330. The adjusting screw sleeve 430 has a first screw hole in the middle that matches the adjusting screw 420. The outer end of the adjusting screw sleeve 430 has a guide slope that matches the inner wall of the guide blind hole 334. The guide slope slides in fit with the inner wall of the guide blind hole 334. One end of the adjusting screw 420 extends to the outside of the housing 310 and is fixedly connected to the handwheel 410. The other end of the adjusting screw 420 passes through the second screw hole and extends into the guide blind hole 334, where it is screwed into the first screw hole. The adjusting screw 420 is rotated by the handwheel 410, driving the adjusting screw sleeve 430 to reciprocate along the axis of the adjusting screw 420 within the guide blind hole 334. When the adjusting screw sleeve 430 reciprocates within the guide blind hole 334, it drives the conductor disk 330 to move closer to or further away from the permanent magnet rotor 320, thereby adjusting the size of the air gap between the two.
[0047] like Figure 6 and Figure 7As shown, the device also includes an air gap adjustment mechanism 400, which is used to flexibly adjust the air gap width between the permanent magnet rotor 320 and the conductor disk 330. The mechanism consists of a handwheel 410, an adjustment screw 420 and an adjustment sleeve 430.
[0048] A second screw hole adapted to the adjusting screw 420 is provided on the outer casing 310. The axis of the second screw hole is parallel to the end face of the conductor disk 330. Both the second screw hole and the conductor disk 330 can be set horizontally. The adjusting screw 420 is a cylindrical metal rod with external threads on its surface, which is screwed into the second screw hole to ensure that the adjusting screw 420 can rotate stably and move along the axis.
[0049] A guide blind hole 334 is formed on the circumferential surface of the conductor disk 330. The hole wall is smooth, and its extension direction forms a certain angle with the end face of the conductor disk 330, providing motion guidance for the adjusting sleeve 430. Figure 6 As shown, the outer end of the guide blind hole 334 is high and the inner end is low; the adjusting screw sleeve 430 is a cylindrical metal sleeve with a first screw hole in the middle that matches the adjusting screw 420, and the outer end is machined into a guide bevel. The bevel fits against the inner wall of the guide blind hole 334 and can slide along the hole wall.
[0050] One end of the adjusting screw 420 extends to the outside of the housing 310 and is fixedly connected to the handwheel 410. The handwheel 410 is disc-shaped with anti-slip texture on the edge, making it easy for the operator to hold and rotate. The other end of the adjusting screw 420 passes through the second screw hole and extends into the guide blind hole 334 to be screwed into the first screw hole.
[0051] When the handwheel 410 is turned, the adjusting screw 420 rotates synchronously, driving the adjusting sleeve 430 to reciprocate along the axis of the adjusting screw 420 within the guide blind hole 334. When the adjusting sleeve 430 moves, the force between the guide inclined surface and the hole wall drives the conductor disk 330 to move closer to or further away from the permanent magnet rotor 320, thereby achieving air gap adjustment.
[0052] Specifically, the adjusting sleeve 430 can be a hexagonal nut with all six sides inclined. The guide blind hole 334 is a hexagonal blind hole that matches the hexagonal nut and extends inclined. All six sides of the hexagonal nut are slidably connected to the inner wall of the guide blind hole 334, and the inner wall of the guide blind hole 334 restricts the hexagonal nut from rotating. When the handwheel 410 is turned clockwise, the adjusting screw 420 rotates clockwise simultaneously, and the adjusting sleeve 430 moves to the left relative to the adjusting screw 420, moving outward within the guide blind hole 334, causing the conductor disk 330 to move downward, and the air gap between the permanent magnet rotor 320 and the conductor disk 330 gradually increases. Similarly, when the handwheel 410 is turned counterclockwise, the adjusting screw 420 rotates counterclockwise simultaneously, and the adjusting sleeve 430 moves to the right relative to the adjusting screw 420, moving inward outside the guide blind hole 334, causing the conductor disk 330 to move upward, and the air gap between the permanent magnet rotor 320 and the conductor disk 330 gradually decreases, causing the conductor disk 330 to move upward. Figure 6 The state becomes Figure 7 state.
[0053] The air gap adjustment mechanism 400 provided in this application breaks the limitation of fixed air gap in traditional devices, and can flexibly adjust the air gap according to actual working conditions, enabling the device to adapt to different wind speeds and different heat demand scenarios, thus improving the device's versatility. When the wind speed is high, adjusting the air gap can prevent the conductor disk 330 from overheating due to excessive magnetic field strength; when the wind speed is low, adjusting the air gap can enhance the magnetic field effect, ensuring that the conductor disk 330 generates sufficient heat energy, effectively improving the device's adaptability to different wind speed environments and broadening its application range.
[0054] The adjustment process is manually operated via handwheel 410, which is simple in structure and easy to operate. It does not require a complex electrical control system, reducing the cost of the device and the risk of failure. At the same time, the air gap adjustment also facilitates the installation, commissioning and maintenance of the device, ensuring the accurate position of each component and guaranteeing the stable operation of the device.

It is vertically mounted on the housing 310 and rotatably connected to the housing 310. The permanent magnet rotor 320 is mounted on the connecting shaft 220 and rotates synchronously with the connecting shaft 220. The bottom end of the connecting shaft 220 is located inside the housing 310 and rotatably connected to the inner wall of the housing 310. The top end of the connecting shaft 220 penetrates the housing 310, and its upper outer wall is rotatably connected to the top of the housing 310 to achieve sealing of the housing 310. The coupling 210 is located inside the tower 110 and is a flexible coupling structure. Its two ends are connected to the bottom of the rotating shaft of the vertical axis wind turbine 120 and the top of the connecting shaft 220, respectively. This compensates for installation misalignment between the two shafts and ensures smooth power transmission. When the vertical axis wind turbine 120 rotates, the coupling 210 drives the connecting shaft 220 to rotate synchronously, providing power to the heating mechanism 300.
[0059] Reference Figure 2 As shown, in some embodiments, the connecting shaft 220 is provided with a mounting plate, which is parallel to the conductor plate 330, and the permanent magnet rotor 320 is fixed on the mounting plate.

[0067] like Figure 2As shown, in some embodiments, the heating mechanism 300 further includes an upper bearing cover 360 and a lower bearing cover 370.

[0070] The working process of the permanent magnet eddy current wind-powered heating device provided in this application is as follows: Wind energy capture and power transmission: The natural wind in the working area acts on the blades of the vertical axis wind turbine 120, driving the blades to rotate, which in turn drives the shaft of the vertical axis wind turbine 120 to rotate. The shaft transmits power to the connecting shaft 220 through the coupling 210, so that the connecting shaft 220 rotates synchronously with the vertical axis wind turbine 120.
[0071] Magnetic field generation: When the connecting shaft 220 rotates, it drives the permanent magnet rotor 320 fixed on the mounting plate to rotate together. Since the magnetic ring group of the permanent magnet rotor 320 adopts a Halbach array arrangement, a periodically changing high-intensity magnetic field will be generated in the air gap during rotation.
[0072] Eddy current generation and heating: When the stationary conductor disk 330 is placed in a changing magnetic field, eddy currents will be induced within the conductor disk 330 according to the law of electromagnetic induction. As the eddy currents flow inside the conductor disk 330, electrical energy is converted into heat energy due to the Joule heating effect, causing the temperature of the conductor disk 330 to rise.
[0073] Heat energy export: The external water supply pipeline delivers the heat exchange medium to the heat exchange channel 331 through the inlet 332. Under the guidance of the extension section, the heat exchange medium enters the serpentine meandering section and fully exchanges heat with the high-temperature conductor plate 330. After absorbing heat energy, the temperature rises and then flows into the external return water pipeline through the outlet 333, delivering the heat energy to areas that need heating or frost protection, such as rest rooms, equipment rooms, etc.
[0074] Air gap adjustment and power control: Operators can adjust the air gap size by rotating handwheel 410 according to actual heat demand and real-time wind speed. When the wind speed is high and the heat demand is low, rotating handwheel 410 clockwise rotates the adjusting screw 420, causing the adjusting sleeve 430 to move outward along the axis of the adjusting screw 420. Through the cooperation of the guide inclined surface and the guide blind hole 334, this pushes the conductor disk 330 downward, increasing the air gap, weakening the eddy current effect, and reducing the heating power. When the wind speed is low and the heat demand is high, rotating handwheel 410 counterclockwise moves the adjusting sleeve 430 inward, causing the conductor disk 330 to move upward, decreasing the air gap, enhancing the eddy current effect, and increasing the heating power. In windy weather, adjusting the large air gap can achieve overload protection of the device, preventing component damage due to overheating.
[0075] The permanent magnet eddy current wind-powered heating device provided in this application eliminates mechanical friction through a non-contact structural design, reducing maintenance costs and energy loss, minimizing downtime for maintenance, and improving operational efficiency. The permanent magnet rotor 320 of the Halbach array significantly enhances the magnetic field strength at the air gap, improving heating efficiency and meeting thermal energy requirements. The air gap adjustment mechanism 400 enables flexible power adjustment to adapt to changes in thermal energy requirements under different operating conditions. The vertical axis wind turbine 120 improves adaptability to wind direction and low wind speed, enabling stable operation in varying wind conditions within the working area.
