[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] Please also refer to Figures 1 to 3 , the integrated wind energy harvesting device that can adapt to a wide speed range provided by the present invention is now described. The integrated wind energy harvesting device that can adapt to a wide speed range includes a mounting seat 10, a drive shaft 20, an internal power generation mechanism 30 and an external power generation mechanism 40. The mounting seat 10 has a accommodating cavity 11. The drive shaft 20 is rotatably arranged on the mounting seat 10, and one end extends out of the accommodating cavity 11 and is connected to the fan blades. The internal power generation mechanism 30 is arranged in the accommodating cavity 11, and the internal power generation mechanism 30 has a rotating ring portion connected to the drive shaft 20. There are multiple external power generation mechanisms 40, each of which is arranged in the accommodating cavity 11, and each of the external power generation mechanisms 40 has a rotating ring portion that is sequentially spaced and sleeved outside the rotating ring portion along the radial direction of the drive shaft 20.

[0043] Specifically, as the drive shaft 20 rotates, the inner power generation mechanism 30 and the outer power generation mechanisms 40 automatically adjust their rotational speed from the inside outward as the wind increases, adapting to varying wind speeds. Driven by the fan blades, the drive shaft 20 rotates, simultaneously driving the rotating ring. As wind speed increases, the rotating ring drives the adjacent outer rotating rings. As wind speed continues to increase, the other rotating rings, in turn, are driven and rotated by their inner adjacent rotating rings, from the inside outward.

[0044] For example, assume wind speed levels of one, two, and three, and two external generators 40 are provided: a second external generator and a third external generator. When the wind speed reaches level one, only the drive shaft 20 drives the rotating ring portion of the internal generator 30 to rotate, and the internal generator 30 generates electricity. When the wind speed reaches level two, as the wind speed increases, the internal generator 30 connects to the rotating ring portion of the second external generator via the rotating ring portion, driving the rotating ring portion to rotate, and the second external generator generates electricity. When the wind speed increases to level three, the second external generator connects to the rotating ring portion of the third external generator via the rotating ring portion, driving the rotating ring portion to rotate.

[0045] This embodiment provides an integrated wind energy harvesting device that can accommodate a wide range of wind speeds. Compared to existing technologies, each external power generation mechanism 40 nests the rotating ring portion of the internal power generation mechanism 30 via coaxially spaced rotating ring portions. During wind energy harvesting, the device automatically adjusts the amount of power generated from the inside outward along the radial direction of the drive shaft 20 as wind speed increases, adapting to varying wind speeds. This arrangement of the internal power generation mechanism 30 and the external power generation mechanisms 40 enhances integration and reduces the space occupied along the axis of the drive shaft 20, facilitating installation. Furthermore, the device can accommodate wind energy harvesting over a wide range of wind speeds, demonstrating its practicality.

[0046] In some embodiments, the internal power generation mechanism 30 may be implemented as follows: Figure 5 The structure shown. Figure 5 The internal power generation mechanism 30 includes a turntable 31, an internal coil 33 and an internal toggle structure 34. The turntable 31 is coaxially arranged on the drive shaft 20. A plurality of internal permanent magnets 32 are provided on the turntable 31. Each internal permanent magnet 32 is arranged at an annular interval around the axis of the drive shaft 20. The internal coil 33 is arranged in the accommodating cavity 11 and corresponds to each internal permanent magnet 32. There are multiple internal toggle structures 34. Each internal toggle structure 34 is arranged at an annular interval around the axis of the drive shaft 20 on the turntable 31. Each internal toggle structure 34 has an internal toggle end that can extend out of the turntable 31 and engage with the rotating ring portion. Each internal toggle structure 34 is combined with the turntable 31 to form a rotating ring portion.

[0047] The turntable 31 is coaxially connected to the drive shaft 20, ensuring that it rotates with the drive shaft 20. The combination of the turntable 31 and the inner coil 33 can respond to the minimum wind speed, thereby ensuring wind energy collection across a wide speed range. The inner toggle structure 34, located on the outer edge of the turntable 31, ensures that when the speed increases and the centrifugal force acts, the inner toggle ends slide outward to engage with the rotating ring portion adjacent to the outer side of the turntable 31, thereby driving the rotating ring portion to rotate.

[0048] The inner permanent magnet arranged in a ring shape on the turntable 31 can correspond to the inner coil 33, thereby ensuring that power generation is performed during the rotation of the turntable 31.

[0049] It should be noted that the inner coil 33 may include multiple sub-coils, each of which is arranged in an annular manner around the axis of the drive shaft 20 and corresponds to each inner permanent magnet 32. Any two adjacent inner permanent magnets 32 are arranged with opposite polarities near the ends of the inner coil 33.

[0050] In this embodiment, a space is formed between any two adjacent inner permanent magnets 32 on the turntable 31, and the positions of the corresponding inner shifting structures 34 can correspond to each space to avoid interference, while also reducing the space occupied in the axial direction of the drive shaft 20.

[0051] In some embodiments, the inner coil 33 may be formed as follows: Figure 5 The structure shown. Figure 5 The inner coil 33 is fixed on the inner wall of the accommodating cavity 11, which has a simple structure and is easier to install.

[0052] Correspondingly, the accommodating cavity 11 may be a cylindrical cavity coaxially arranged with the driving shaft 20 , and the inner coil 33 may be fixedly arranged on the bottom surface away from the fan blades.

[0053] In some embodiments, the inner dial structure 34 may be configured as follows: Figure 5 The structure shown. Figure 5 Each internal driving structure 34 includes an internal claw 341 and an internal tension spring 342. The internal claw 341 is arranged in the internal embedded groove on the turntable 31, and one end of the internal claw 341 is rotatably connected to the turntable 31, and the rotation axis is parallel to the axis of the turntable 31. The internal claw 341 can flip outward under the action of centrifugal force as the turntable 31 rotates. The other end of the claw is the internal driving end. The internal tension spring 342 is arranged in the internal embedded groove, and one end of the internal tension spring 342 is connected to the turntable 31, and the other end is connected to the internal claw 341, which can continuously pull the internal claw 341 so that the internal claw 341 maintains a tendency to flip into the internal embedded groove.

[0054] When there is no wind or the wind speed is insufficient to drive the drive shaft 20 to rotate, the internal tension spring 342 pulls the internal clamping claw 341, causing it to retract into the internal mounting groove. At this time, the turntable 31 cannot engage with the rotating ring portion adjacent to its outer side. When the wind speed increases, the centrifugal force on each clamping claw increases, and the other end will flip outward, engaging with the rotating ring portion adjacent to its outer side, thereby starting to drive the rotating ring portion to rotate. By automatically adjusting the rotation amount of the turntable 31 and each rotating ring portion by utilizing centrifugal force, it can adapt to different wind speeds and achieve automatic connection. The connection is more stable and practical.

[0055] In some embodiments, the external power generation mechanism 40 may be configured as follows: Figure 2 and Figure 3 See the structure shown. Figure 2 and Figure 3 Each external power generation mechanism 40 includes a connecting frame 41, an annular disk 42, an external coil 44 and an external toggle structure 45. The connecting frame 41 is rotatably connected to the drive shaft 20. The annular disk 42 is coaxially arranged with the drive shaft 20 and fixedly connected to the connecting frame 41. A plurality of external permanent magnets 43 are provided on the annular disk 42, and each external permanent magnet 43 is arranged at an annular interval around the axis of the drive shaft 20. The external coil 44 is arranged in the accommodating cavity 11 and corresponds to each external permanent magnet 43. There are multiple external toggle structures 45, and each external toggle structure 45 is arranged at an annular interval around the axis of the drive shaft 20 on the annular disk 42. Each external toggle structure 45 has an external toggle end that can extend out of the annular disk 42 and be clamped with the annular disk 42 adjacent to its outer side. Each external toggle structure 45 is combined with the annular disk 42 to form a rotating ring portion.

[0056] The connecting frame 41 is rotatably connected to the drive shaft 20. The connecting frame 41 can ensure that the annular disk 42 is fixedly connected. This can limit the annular disk 42 in the axial direction of the drive shaft 20 to ensure that the annular disk 42 is arranged along the radial direction of the rotating disk 31. The annular disk 42 can be driven to rotate, thereby driving the external permanent magnet 43 to rotate. The external permanent magnet arranged in an annular shape on the annular disk 42 can correspond to the external coil 44, thereby ensuring that power generation is generated during the rotation of the annular disk 42. Each external toggle structure 45 can ensure that after the annular disk 42 reaches a certain speed, the external toggle end extends outward and engages with the annular disk 42 adjacent to the outside, thereby toggling the adjacent annular disk 42 to rotate, thereby automatically adjusting the power generation level according to different wind speeds.

[0057] In addition, as the diameter of the annular disk 42 gradually increases, the diameters of the corresponding coils and external permanent magnets also gradually increase, and the number will also gradually increase, which can ensure an increase in power generation efficiency.

[0058] It should be noted that the outer coil 44 may include multiple sub-coils, each of which is arranged in an annular manner around the axis of the drive shaft 20 and corresponds to each external permanent magnet 43. Any two adjacent external permanent magnets 43 are arranged with opposite polarities near the ends of the outer coil 44.

[0059] In this embodiment, a space is formed between any two adjacent external permanent magnets 43 on the turntable 31, and the positions of the corresponding external actuating structures 45 can correspond to each space to avoid interference, while also reducing the space occupied in the axial direction of the drive shaft 20.

[0060] It should be noted that each connecting frame 41 can be located on the side of the turntable 31 away from the inner coil 33, and each connecting frame 41 and the turntable 31 are arranged at intervals in the axial direction of the drive shaft 20.

[0061] In some embodiments, the above-mentioned connecting frame 41 can adopt the structure shown in Fig. 2. Refer to Figure 2 , a bearing 46 is provided between the connecting frame 41 and the drive shaft 20. The setting of the bearing 46 can ensure reducing friction, and further ensure the rotational connection between the connecting frame 41 and the drive shaft 20.

[0062] As another implementation manner of this embodiment, refer to Figure 4 , the mounting seat 10 can include a cylinder body and an end cover 12 detachably connected to the cylinder body. A sleeve 13 sleeved on the drive shaft 20 can be connected to the end cover 12, and the sleeve 13 is located in the accommodating cavity 11. One end of the sleeve 13 is close to but does not contact the turntable 31. Preferably, the sleeve 13 and the drive shaft 20 are in clearance fit, and rolling bearings can be provided between them.

[0063] When it comes to the connection between the bearing 46 and the drive shaft 20, it will occupy a large space in the axial direction of the drive shaft 20, and the disassembly and assembly of the bearing 46 are not convenient. Therefore, in order to further reduce the space, the connecting frame 41 can also be sleeved on the sleeve 13. The connecting frame 41 is provided with a sleeving hole, and an annular groove is provided in the sleeving hole, and a plurality of balls are arranged around in the annular groove.

[0064] At this time, each connecting frame 41 will move in the axial direction of the drive shaft 20. For this, each external power generation mechanism 40 can also include a plurality of two fixed magnetic rings 47 and a plurality of magnetic levitation structures respectively corresponding to each connecting frame 41 one by one. The two fixed magnetic rings 47 are respectively fixedly arranged on the turntable 31 and the end cover 12, and are coaxially arranged with the drive shaft 20. Each magnetic levitation structure includes two moving magnetic rings 48. The two moving magnetic rings 48 are respectively fixedly arranged on both sides of the corresponding connecting frame 41, and the opposite end faces of the two moving magnetic rings 48 are set with opposite polarities. For any two adjacent connecting frames 41, the moving magnetic rings 48 on the opposite side faces are set with opposite polarities. The fixed magnetic ring 47 on the turntable 31 and the moving magnetic ring 48 on the adjacent and opposite side face of the connecting frame 41 are set with the same polarity. The fixed magnetic ring 47 on the end cover 12 and the moving magnetic ring 48 on the adjacent and opposite side face of the connecting frame 41 are set with the same polarity.

[0065] This structure can limit the position of each connecting frame 41 in the axial direction of the drive shaft 20. The connecting frame 41 repels the connecting frame 41, or the connecting frame 41 repels the end cover 12, or the connecting frame 41 repels the turntable 31, thereby avoiding collisions, and at the same time, it is also convenient for the disassembly and assembly of each connecting frame 41.

[0066] In some embodiments, the above-mentioned outer coil 44 can adopt Figure 2 andFigure 5 The structure shown. Figure 2 and Figure 5 The outer coil 44 is fixed on the inner wall of the accommodating cavity 11, which has a simple structure and is easier to install.

[0067] Correspondingly, the accommodating cavity 11 may be a cylindrical cavity coaxially arranged with the driving shaft 20 , and the inner coil 33 may be fixedly arranged on the bottom surface away from the fan blades.

[0068] In some embodiments, the external dial structure 45 can be used as follows Figure 2 The structure shown. Figure 2 Each external driving structure 45 includes an external claw 451 and an external tension spring 452. The external claw 451 is set in the external embedded groove on the annular disk 42. One end of the external claw 451 is rotatably connected to the annular disk 42, and the rotation axis is parallel to the axis of the annular disk 42. The external claw 451 can flip outward under the action of centrifugal force as the annular disk 42 rotates. The other end of the claw is the external driving end. The external tension spring 452 is set in the external embedded groove. One end of the external tension spring 452 is connected to the annular disk 42, and the other end is connected to the external claw 451. It can continuously pull the external claw 451 so that the external claw 451 maintains a tendency to flip into the external embedded groove.

[0069] As the wind speed increases, the annular disk 42 adjacent to the turntable 31 rotates and reaches a certain speed. The outer claws 451 on this annular disk 42 extend outward and engage with the outer adjacent annular disk 42, thereby driving the outer adjacent annular disk 42 to rotate. As the wind speed continues to increase, the next annular disk 42 repeats this action, gradually driving all the annular disks 42 to rotate. By automatically adjusting the rotation speed of the turntable 31 and each rotating ring part using centrifugal force, the system can adapt to different wind speeds and achieve automatic connection, with higher connection stability and stronger practicality.

[0070] It should be noted that a deceleration ring can be fixedly installed in the accommodating chamber 11. The deceleration ring is arranged outside the outermost annular disk 42 to ensure that the outermost toggle structure can achieve deceleration after contact, thereby preventing the rated working strength from being exceeded due to excessive wind speed. Of course, the outermost toggle structure 45 can also be omitted on the outermost annular disk 42.

[0071] In some embodiments, the annular disk 42 may be formed as follows: Figure 2 and Figure 3 The structure shown. Figure 2 and Figure 3 A plurality of limit engaging positions 421 are provided on the inner ring surface of the annular disk 42 for easy engagement with the inner dial structure 34 on the adjacent rotating disk 31 or the outer dial structure 45 on the annular disk 42 .

[0072] Specifically, the optional structure of the limit clamping position 421 in this embodiment is an annular sawtooth or an annular one-way sawtooth.

[0073] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
