The embodiments of this invention will now be described according to its overall structure.

[0019] Example 1: Please see Figures 1-5 The present invention discloses a power regulation and transmission device for airborne transmission of magnetic eddy current energy, comprising a frame; a protective rotating cylinder 2 is rotatably mounted inside the frame 1, and a hollow motor 3 with driving function is fixedly mounted on the side of the frame 1 by bolts; an input shaft 5 with transmission function is provided inside the hollow motor 3, and the input shaft 5 is inserted and fixed at the through hole on the side of the protective rotating cylinder 2; a multi-layer conductor assembly 6 is fixedly mounted on the left and right inner walls of the protective rotating cylinder 2, and a photoelectric sensor 7 with photoelectric sensing function is also fixedly mounted on the arc-shaped inner wall of the protective rotating cylinder 2; a magnetic levitation bearing 8 is fixedly mounted on the through hole on the right side of the protective rotating cylinder 2, and an output shaft 9 is inserted and fixedly mounted inside the magnetic levitation bearing 8; an output device 4 is inserted and fixedly mounted at the right end of the output shaft 9; two sets of grooves are provided on the left side of the output shaft 9, and positioning keys 10 are inserted and fixedly mounted inside the grooves; an isolation plate 11 is slidably provided on each of the two sets of positioning keys 10 at the left end of the output shaft 9, and a magnetic conductor 12 is fixedly mounted on the opposite side of the two sets of isolation plates 11.

[0020] An insulating disk 11 has a light source 13 that cooperates with the photoelectric sensor 7 inserted and fixed on its outer ring surface; an insulating cylinder 14 is sleeved and fixed between the two sets of positioning keys 10 on the output shaft 9.

[0021] The output shaft 9 is fixedly connected to the inner and outer cylinders of the sleeve structure 15, and a magnetic circuit module is fixedly installed between the inner and outer cylinders of the sleeve structure 15; six sets of light source components 13 are arranged at equal angles along the outer ring surface of the isolation disk 11, and the photoelectric sensor 7 corresponds one-to-one with the light source component 13 to form a closed-loop detection module.

[0022] A transmission gap is left between the left end of the output shaft 9 and the inner wall of the left side of the protective rotating cylinder 2. The magnetic conductor 12 and the multi-layer conductor assembly 6 are arranged coaxially. A through groove is provided on the top of the positioning key 10. A connecting rod is provided at the sliding part of the isolation plate 11 and the positioning key 10. The bottom of the connecting rod is connected to a synchronization component set inside the positioning key 10. The synchronization component is composed of an electromagnetic spring with electromagnetic drive and a sensor set on its side to ensure that the width of the left and right working air gaps between the two sets of magnetic circuit modules and the corresponding conductor cylinders is always the same.

[0023] Example 2: Please see Figures 1-5 The present invention provides a power adjustment and transmission device for the air-to-air transmission of magnetic eddy current energy. Compared with Embodiment 1, this embodiment further includes: a multi-layer conductor assembly 6 comprising two sets of positioning discs 61 fixedly installed on the left and right inner walls of the protective rotating cylinder 2; a spring plate 62 with thermal compensation is fixedly installed on the positioning disc 61, and the side of the spring plate 62 is fixedly installed with the outer rod of the sleeve rod 63; the inner and outer rods of the sleeve rod 63 are respectively fixedly installed with the positioning disc 61 and the side wall of the conductor cylinder 64.

[0024] The conductor cylinder 64 of the multilayer conductor assembly 6 has annularly arranged heat dissipation grooves on its edge, and the heat dissipation grooves are arc-shaped through grooves, which are distributed at equal intervals along the radial direction of the conductor cylinder.

[0025] The working principle of the above-mentioned power regulation and transmission device for the air-to-air transfer of magnetic eddy current energy is as follows: When using this device, first place it in the work area, then connect it to an external power source to provide the power required for its operation. During operation, the hollow motor 3 serves as the power source to drive the input shaft 5 to rotate and drive the protective rotating cylinder 2 to rotate synchronously within the frame 1. The protective rotating cylinder 2 acts as the active rotor, and multi-layer conductor assemblies 6 are fixedly installed on its left and right inner walls. Therefore, when the protective rotating cylinder 2 rotates, the conductor cylinder 64 in the multi-layer conductor assembly 6 also rotates accordingly. Meanwhile, the output shaft 9 is suspended in the right through hole of the protective rotating cylinder 2 via the magnetic levitation bearing 8. An isolation disk 11 is slidably installed on the left end of the output shaft 9 via two sets of positioning keys 10. A magnetic conductor 12 is fixedly installed on the opposite side of the isolation disk 11. A magnetic circuit module is also installed on the output shaft 9 via the sleeve structure 15. The layered magnetic circuit structure significantly reduces magnetic leakage, improves energy transfer efficiency, reduces the temperature rise of the permanent magnet, delays demagnetization, and extends service life. The magnetic circuit module and the multilayer conductor assembly 6 are arranged coaxially, with a transmission gap between them. When the protective rotating cylinder 2 drives the conductor cylinder 64 to rotate, the conductor cylinder 64 cuts the magnetic field generated by the magnetic circuit module. According to the principle of electromagnetic induction, eddy currents are induced inside the conductor cylinder 64. The induced magnetic field generated by the eddy currents interacts with the original magnetic field of the magnetic circuit module to generate electromagnetic torque, which drives the magnetic circuit module to overcome the air gap and follow the rotation. Since the magnetic circuit module is connected to the output shaft 9 through the sleeve structure 15, the output shaft 9 is driven to rotate, and the power is transmitted to the output device 4 that is plugged and fixed at the right end of the output shaft 9, thereby realizing non-contact air-sealed power transmission from the input side to the output side. When the output power needs to be adjusted, the magnetic circuit module on the sleeve structure 15 is synchronously energized to generate a magnetic field between the two. The magnetic field repulsion pushes the inner and outer cylinders of the sleeve structure 15 to slide axially on the output shaft 9, changing the air gap length between the magnetic conductor 12 and the multilayer conductor assembly 6. When the air gap decreases, the magnetic field coupling is enhanced, and the transmitted torque increases; when the air gap increases, the magnetic field coupling is weakened, and the transmitted torque decreases. During the power adjustment process, the electromagnetic spring in the positioning key 10 drives the isolation disk 11 and the sleeve structure 15 to move synchronously towards or away from each other, so that the air gaps on the left and right sides are consistent. This avoids problems such as uneven axial force, shaft wobble, and increased vibration caused by an excessively small or large air gap on one side, and achieves stable, balanced, and unbiased transmission under high-speed and heavy-load conditions. Meanwhile, the conductor cylinder 64 generates a large amount of heat due to the eddy current effect, resulting in a greater thermal expansion than the positioning disk 61 and sleeve rod 63. At this time, the side wall of the conductor cylinder 64 transmits the expansion force to the spring plate 62 through the sleeve rod 63. The spring plate 62 undergoes elastic deformation to absorb the excess thermal expansion. When the temperature drops, the spring plate 62 rebounds and resets, allowing the conductor cylinder 64 to return to its initial position. This avoids bulging deformation or fixation failure caused by thermal stress, ensuring the accuracy and structural stability of long-term operation. During device operation, six sets of light source elements 13, arranged at equal angles along the outer ring surface of the isolation disk 11, rotate synchronously with the isolation disk 11, forming a closed-loop detection module with the photoelectric sensors 7 fixed on the arc-shaped inner wall of the protective rotating cylinder 2 and corresponding to each other. By detecting the pulse signal between the light source elements 13 and the photoelectric sensors 7 and analyzing the frequency and phase of the pulse signal, the rotational speed data of the output shaft 9 can be obtained in real time, and this information can be fed back to the external control system to accurately adjust the input power of the hollow motor 3 or the levitation state of the magnetic levitation bearing 8, thereby realizing closed-loop control. In addition, the annular heat dissipation grooves opened on the edge of the conductor cylinder 64 use airflow to accelerate heat dissipation during rotation, thereby reducing the operating temperature.

[0026] This invention provides an improved power regulation and transmission device for air-to-air transmission of magnetic eddy current energy. Non-contact transmission is achieved through magnetic eddy current coupling, completely eliminating mechanical friction losses. Combined with the support of the magnetic levitation bearing 8, it can meet the requirements of higher speed operation. The axial sliding of the sleeve structure 15 changes the air gap length between the magnetic circuit module and the conductor cylinder 64, allowing flexible adjustment of the transmitted torque and speed to adapt to different load conditions. When the conductor cylinder 64 heats up and expands, its sidewall transmits the expansion force to the spring plate 62 through the sleeve rod 63. The spring plate elastically deforms to absorb the thermal expansion, and rebounds to its original position after the temperature drops, effectively solving the bulging problem caused by thermal deformation and ensuring long-term operational accuracy. The closed-loop detection module composed of the light source 13 and the photoelectric sensor 7 can acquire the speed and position information of the output shaft 9 in real time and feed it back to the control system, realizing precise closed-loop adaptive control. In addition, the heat dissipation grooves on the edge of the conductor cylinder 64 utilize rotating airflow to accelerate heat dissipation, the magnetic conductor 12 optimizes the magnetic field distribution to reduce magnetic leakage, and the isolation cylinder 14 prevents foreign objects from entering.
