[0023] The high-efficiency vertical-axis forward and reverse wind turbine of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0024] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example 1

[0025] See also Figure 1-Figure 2 The high-efficiency vertical axis forward and reverse wind turbine of this embodiment can significantly improve the conversion efficiency of wind energy into mechanical energy and electrical energy through the design that the rotor and stator rotate simultaneously and in opposite directions, make full use of the energy captured by the wind turbine, and reduce energy loss. In this embodiment, it mainly includes a motor inner rotor 1 and a motor outer rotor 2 that can rotate in opposite directions. The motor inner rotor 1 is coaxially rotatably arranged inside the motor outer rotor 2, and the bottom of the motor outer rotor 2 is fixedly provided with an outer rotor lower shaft 14, and the bottom of the motor inner rotor 1 is rotatably arranged with the outer rotor lower shaft 14.

[0026] The inner rotor 1 and the outer rotor 2 of the motor are respectively connected to corresponding impellers on the outside. The inner rotor 1 and the outer rotor 2 of the motor rotate in opposite directions on the lower shaft 14 of the outer rotor, thereby improving the relative speed of the inner rotor 1 and the outer rotor 2 of the motor, increasing the efficiency of power generation, making full use of the energy captured by the wind turbine, and reducing energy loss. Example 2

[0027] The same points as in Example 1 will not be described in detail, except that: See also Figure 3-Figure 6The outer portion of the motor inner rotor 1 is provided with a housing 5 that can support the motor inner rotor 1 and the motor outer rotor 2. The housing 5 includes a lower housing 501 and an upper housing 502 that can be detachably arranged from each other.

[0028] The motor inner rotor 1 includes a vertically arranged motor housing 11, a stator body 12 is coaxially arranged inside the motor housing 11, and the lower housing 501 is sleeved on the outside of the motor housing 11. A first bearing 13 is arranged between the lower part of the lower housing 501 and the bottom end of the motor housing 11. The motor housing 11 drives the stator body 12 to rotate on the motor housing 11 through the first bearing 13. The rotor body 21 coaxially rotates inside the stator body 12, and a central shaft 22 is vertically fixed in the middle of the rotor body 21, and both ends of the central shaft 22 pass through the ends of the motor housing 11. The rotor body 21 rotates inside the stator body 12.

[0029] To achieve synchronous rotation, see Figure 4-Figure 6 , a connecting unit 3 adapted to the outer rotor 2 of the motor is provided at the bottom end of the inner rotor 1 of the motor. The connecting unit 3 includes a first gear 31 coaxially fixedly provided at the bottom end of the central shaft 22, and a connecting ring 32 is fixedly provided at the bottom of the motor housing 11. A gear ring 33 is fixedly provided at the bottom end of the connecting ring 32, and at least one second gear 34 is rotatably provided at the lower part of the lower housing 501, and the second gear 34 is respectively meshed with the first gear 31 and the gear ring 33. When the rotor body 21 rotates, the central shaft 22 drives the first gear 31 to rotate, thereby driving the gear ring 33 to rotate through the second gear 34 on the lower housing 501, and at this time, the motor housing 11 drives the stator body 12 to rotate. Conversely, the same applies.

[0030] The top of the inner rotor 1 of the motor is provided with a synchronization unit 4 adapted to the outer rotor 2 of the motor. The synchronization unit 4 includes a sleeve 41 vertically arranged above the motor housing 11, and a first ratchet 42 is detachably arranged at the bottom of the sleeve 41. The direction of the first ratchet 42 can be set according to actual conditions. A pad 43 is fixedly arranged at the top of the motor housing 11, and at least one first ratchet block 44 is rotatably arranged at the top of the pad 43, and the first ratchet block 44 can engage with the first ratchet 42. A first spring 45 is fixedly arranged at the top of the pad 43, and the end of the first spring 45 is fixedly arranged with the side of the first ratchet block 44. A baffle 46 is horizontally fixedly arranged on the outer wall of the sleeve 41, and the upper shell 502 is sleeved on the outside of the sleeve 41, and a second bearing 47 is arranged between the top of the upper shell 502 and the bottom end of the baffle 46. When the sleeve 41 is the active part and rotates on the upper housing 502 through the second bearing 47, the first ratchet 42 is driven to rotate. At this time, the first ratchet 42 pushes the first ratchet block 44 to rotate the gasket, thereby rotating the motor housing 11. When the gasket is the active part and rotates in the same direction, the first ratchet block 44 is disconnected from the first ratchet 42, thereby disconnecting the power output. In this process, the first spring 45 always abuts the first ratchet block 44 and the first ratchet 42. Conversely, the same applies.

[0031] A rotating shaft 48 is coaxially arranged inside the sleeve 41, a lower plate 49 is horizontally fixedly arranged on the inner wall of the sleeve 41, an upper plate 50 is horizontally fixedly arranged on the rotating shaft 48 above the lower plate 49, and a third bearing 51 is arranged between the top end of the lower plate 49 and the bottom end of the upper plate 50. The rotating shaft 48 rotates on the lower plate 49 through the upper plate 50 and the third bearing 51. A second ratchet 52 is detachably arranged at the bottom end of the rotating shaft 48, and the direction of the second ratchet 52 can be set according to actual conditions. The direction of the second ratchet 52 is opposite to the rotation direction of the first ratchet 42. At least one second ratchet block 53 is rotatably arranged at the top end of the central shaft 22, and the second ratchet block 53 can be engaged with the second ratchet 52. A second spring 54 is fixedly arranged at the top end of the central shaft 22, and the end of the second spring 54 is fixedly arranged on the side of the second ratchet block 53. When the rotating shaft 48 is the active part, it drives the second ratchet block 53 to rotate. At this time, the second ratchet wheel 52 pushes the second ratchet block 53 to rotate the central shaft 22. When the central shaft 22 is the active part, it rotates in the same direction, and the second ratchet block 53 is disconnected from the second ratchet wheel 52, thereby disconnecting the power output. In this process, the second spring 54 always abuts the second ratchet block 53 and the second ratchet wheel 52. Conversely, the same applies.

[0032] Therefore, the double ratchet design ensures that the rotation speeds of the rotor body 21 and the stator body 12 are always the same, thereby maintaining a stable working state of the system and ensuring the reliability and long life of the system.

[0033] The working principle of the second embodiment of the present invention is as follows: First, when the sleeve 41 is an active member under the action of external force and rotates on the upper housing 502 through the second bearing 47, the first ratchet 42 is driven to rotate. At this time, the first ratchet 42 pushes the first ratchet block 44 to rotate the gasket, thereby rotating the motor housing 11. At this time, the motor housing 11 drives the stator body 12 to rotate. At the same time, the motor housing 11 drives the second gear 34 on the lower housing 501 to rotate through the gear ring 33, and the second gear 34 drives the central shaft 22 to rotate through the first gear 31. At this time, the central shaft 22 drives the rotor body 21 to rotate to realize the synchronous rotation of the rotor body 21 and the stator body 12. At the same time, the second ratchet block 53 is disconnected from the second ratchet 52, thereby disconnecting the power output between the central shaft 22 and the rotating shaft 48. Conversely, the same applies. Therefore, no matter which speed of the sleeve 41 and the rotating shaft 48 is faster, the synchronous rotation of the rotor body 21 and the stator body 12 can be realized. In this process, the housing 5 composed of the lower housing 501 and the upper housing 502 provides support and protection for the motor.
