The coupling device is coaxially and movably connected inside the housing structure. The induction generator is coaxially and rotatably connected inside the housing structure after the coupling device. The heat dissipation device is movably connected outside the induction generator.

[0023] Furthermore, the outer shell structure includes a base 1, a front cover 2, a rear cover 3, and legs 4. The base 1 is cylindrical in shape, with an opening on one circular side that extends to the other circular side. Legs 4 are symmetrically fixed on the outer surface of the base 1, and through holes for fixing are provided on the legs 4. The front cover 2 is fitted onto one circular side of the base 1, and the rear cover 3 is fitted onto the other circular side. The rear cover 3 has dense heat dissipation holes.

[0024] Furthermore, the induction power generation device includes a rotating shaft 10, a stator core 11, an end ring 13, a rotating core 15, and a metal rod 16. The rotating shaft 10 is coaxially connected to the base 1. The rotating core 15 is sleeved on the rotating shaft 10. The rotating core 15 has multiple sets of through holes in a ring shape. The metal rod 16 passes through the through holes and is fixedly connected to the rotating core 15. The two ends of the rotating core 15 are fixedly connected to the end ring 13. The stator core 11 has multiple sets of grooves in a ring shape inside, and the stator core 11 is sleeved on the outside of the rotating core 15.

[0025] Furthermore, the coupling device includes a fixing block 5, a spring 6, a wrench 7, a fixing cylindrical block 8, and a chuck 9. The fixing block 5 has a through hole and is sleeved on the rotating shaft 10. The spring 6 is fixedly connected to one side of the fixing block 5, and the fixing cylindrical block 8 is fixedly installed at the other end of the spring 6. Cylindrical protrusions are symmetrically fixed on the arc surface of the fixing cylindrical block 8. The wrench 7 is rotatably connected to the pair of cylindrical protrusions. The chuck 9 is fixedly installed on the other side of the fixing cylindrical block 8. The chuck 9 has a triangular groove on the surface away from the contact with the fixing cylindrical block 8. The design of the coupling has been optimized, making it easier to install.

[0026] Furthermore, the heat dissipation device includes a protective cover 14, heat sinks 17, heat pipes 19, and an inner shell 21. The protective cover 14 is fitted onto the outer layer of the stator core 11. Multiple sets of grooves are arranged in a circumferential array on the outer surface of the protective cover 14. Heat sinks 17 are fitted into these grooves. The heat sinks 17 are rack-shaped, and the outer ends of the heat sinks 17 are fitted with the inner shell 21. A heat pipe 19 is fitted into the cavity between the inner shell 21 and the base 1. A bearing 12 is fitted onto the front end of the rotating shaft 10 corresponding to the rotating core 15, and a fan 18 is fitted onto the rear end of the rotating shaft 10 corresponding to the rotating core 15. By installing heat sinks 17 between the segmented stator and rotor, and adding heat pipes 19 externally, the heat dissipation effect can be significantly improved. These heat sinks 17 provide a larger surface area in contact with air, contributing to more efficient heat dissipation.

[0028] Working principle: An opening is provided at the bottom of the support leg 4 for installing a fixing device. When production is in progress, the motor is started. Once the windings on the internal stator core 11 are connected to AC power, the rotor core 15 will immediately start rotating and drive the rotating shaft 10 to output power. The stator core 11 and rotor core 15 generate heat when rotating. The heat is transferred to the heat sink 17 through the protective cover 14. The heat sink 17 has a large contact area with the air and good heat dissipation. Moreover, the irregular toothed rack on the heat sink 17 allows natural wind to pass through the gaps. In addition, fan 18 is responsible for introducing cool air into the motor, while fan 20 forces hot air out. The two fans can automatically adjust their speed according to the motor temperature to achieve dynamic heat dissipation control. When the motor needs to be connected to other objects, the wrench 7 is pulled down to move the fixed cylindrical block 8 and the chuck 9 downward. After the chuck 9 is engaged with the object, the wrench 7 is released, and the motor can be connected to other objects.
