At least two fixed rings are fixed on the central shaft by pins and are sleeved on the central shaft. A guide slider is provided below each fixed ring and can slide axially along the central shaft and sleeved on the central shaft. The support layer is composed of support rods of equal length that are hinged to the guide sliders, centered on the guide sliders, and radiate at the same interval angle. The support rods are hinged to the fixed rods, and the support rods are connected to the fixed rings by pull rods. The pull rods are hinged to the support rods and the fixed rings respectively, and the support rods are connected to the guide sliders by tension springs. Summary of the Invention

[0007] In the above-mentioned small wind turbine, the lifting structure includes a rotating drum rotatably connected to the bracket drum, the rotating drum is arranged at the top end of the bracket drum, and a screw-on drum is provided on the rotating drum. The screw-on drum extends into the vertical column and is screwed to the vertical column. The outer surface of the vertical column is also provided with an extended support structure, and the extended support structure can be supported on the ground or a plane after being unfolded.

[0008] In the above-mentioned small wind turbine, the extended support structure includes a plurality of lifting slots arranged on the vertical pillars, a lifting block is slidably connected in the lifting slots, a support rod is rotatably connected in the lifting block, and the support rod can be placed in the lifting slots. A stop member is also provided on the vertical pillar, and the stop member can be against the upper end of the lifting block.

[0009] In the above-mentioned small wind turbine, the stop member is a frame ring rotated on the vertical pillar, and the lifting groove is partially arranged in the frame ring. The rotation of the frame ring can cause the lifting groove to be located in a part of the frame ring and a part of the lifting groove to be located in the vertical pillar to be staggered.

[0010] In the above-mentioned small wind turbine, the lifting slot extends to the bottom end of the vertical support, and a rubber pad is provided on the inner wall of the bottom end of the lifting slot, and the support rod can be embedded in the rubber pad.

[0011] In the above-mentioned small wind turbine, a plurality of frame rings are provided on the vertical pillar, and the plurality of frame rings are independently arranged.

[0012] In the above-mentioned small wind turbine, a micro-pitch adjustment support shaft is screwed to the bottom end of the support rod, and the micro-pitch adjustment support shaft can extend out of the support rod along the axial direction of the support rod.

[0016] Compared with the existing technology, the advantages of the present invention are:

[0017] 1. The small wind turbine can be extended and is in an unextended state when not in use, which is convenient for loading and unloading. Since the small wind turbine is usually used in a low-altitude environment, the wind force is weaker than that at high altitude. By extending the tail wing, the distance from the generator assembly is lengthened, so that the tail wing can be more suitable for conditions with weak winds and can keenly sense the direction of the wind. If the distance between the tail wing and the generator assembly is too short, it is easy to cause the wind impeller to not face the wind direction in a breeze.

[0018] 2. Since the supporting structure of the small wind turbine is a column, it is easy to fall over when in use. Therefore, an extended supporting structure is used to support the four sides of the column to maintain the stability of the small wind turbine. When not in use, the extended supporting structure is also in a retracted state, which is convenient for loading and unloading.

[0019] 3. When the placement surface is not flat and has height differences, this problem can be overcome by micro-adjusting the extension of the support shaft to further ensure the stability of the small generator. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This embodiment provides a small wind turbine generator. Figure 1-4 As shown, it includes a bracket tube 10, and a vertical column 11 is provided on the bracket tube 10. The top of the vertical column 11 is rotatably connected to the power generation frame 12, and one end of the power generation frame 12 is rotatably connected to the wind impeller 13. The power generation frame 12 is provided with a generator assembly connected to the wind impeller 13, and the other end of the power generation frame 12 is provided with a tail 14. The tail 14 and the power generation frame 12 are provided with a length adaptation adjustment structure 15, and the tail 14 adjusts the distance between it and the power generation frame 12 through the length adaptation adjustment structure 15. The vertical column 11 is also connected to a lifting structure 16, and the vertical column 11 is slidably connected to the bracket tube 10 through the lifting structure 16.

[0027] In this embodiment, the small wind turbine can be extended and is in an unextended state when not in use, which is convenient for loading and unloading. When in use, the small wind turbine is placed in a suitable position, the bracket tube 10 is placed on the placement surface, and the tail 14 is moved outward through the length adaptation adjustment structure 15. Then, the vertical pillar 11 is moved upward with the power generation component through the lifting structure 16 to complete the extension of the small wind turbine. Since the small wind turbine is usually used in a low-altitude environment, the wind force is weaker than that at high altitude. By extending the tail 14, the distance from the generator component is lengthened, so that the tail can be more suitable for weak wind conditions and can keenly sense the wind direction. If the distance between the tail 14 and the generator component is too short, it is easy to cause the wind impeller 13 to not face the wind direction in a breeze.

[0028] The lifting structure 16 includes a rotating cylinder 17 rotatably connected to the bracket cylinder 10. The rotating cylinder 17 is arranged at the top of the bracket cylinder 10. A screw-on cylinder 18 is provided on the rotating cylinder 17. The screw-on cylinder 18 extends into the vertical support 11 and is screwed to the vertical support 11. The outer surface of the vertical support 11 is also provided with an extended support structure 19. The extended support structure 19 can be supported on the ground or a plane after being unfolded.

[0029] In this embodiment, since the supporting structure of the small wind turbine is a pillar, it is easy to fall over during use. Therefore, the extended support structure 19 is used to support the pillar around it to maintain the stability of the small wind turbine. When not in use, the extended support structure 19 is also in a retracted state, which is convenient for loading and unloading.

[0030] The extended support structure 19 includes a plurality of lifting slots 20 arranged on the vertical pillars 11, and a lifting block 21 is slidably connected to the lifting slots 20, and a support rod 22 is rotatably connected to the lifting block 21. The support rod 22 can be placed in the lifting slots 20. A stop member is also provided on the vertical pillar 11, and the stop member can be against the upper end of the lifting block 21.

[0031] In this embodiment, when the extended support structure 19 plays a supporting role, the support rod 22 rotates and extends outward, and the lifting block 21 moves downward so that the bottom end of the support rod 22 is supported on the placement surface. Then, the stop member is pressed against the upper end of the lifting block 21 to prevent the lifting block 21 from moving upward, thereby playing a supporting role. When not in use, the support rod 22 is hidden in the lifting slot 20, which further facilitates loading and unloading.

[0032] The stopper is a frame ring 23 that rotates on the vertical pillar 11, and the lifting groove 20 is partially set in the frame ring 23. The rotation of the frame ring 23 can cause the part of the lifting groove 20 located in the frame ring 23 to be staggered with the part of the lifting groove 20 located in the vertical pillar 11.

[0033] In this embodiment, when the lifting block 21 is lowered to a suitable position, the frame ring 23 is rotated so that a portion of the lifting slot 20 located at the frame ring 23 is offset from a portion of the lifting slot 20 located at the vertical support 11, thereby allowing the lifting block 21 to rest against the frame ring 23 and thereby play a supporting role.

[0034] The lifting groove 20 extends to the bottom end of the vertical support 11 . A rubber pad 24 is provided on the inner wall of the bottom end of the lifting groove 20 , and the support rod 22 can be embedded in the rubber pad 24 .

[0035] In this embodiment, when the support rod 22 is not in use, it is embedded in the rubber pad 24. The rubber pad 24 can clamp the support rod 22 to prevent it from extending out of the lifting slot 20, thereby further facilitating loading and unloading.

[0036] The vertical support 11 is provided with a plurality of frame rings 23 , and the plurality of frame rings 23 are independently provided.

[0037] In this embodiment, a plurality of frame rings 23 are used to form a plurality of support positions at different heights. Frame rings 23 of appropriate heights are selected as support positions according to the height of the generator assembly.

[0038] The bottom end of the support rod 22 is screwed with a macro adjustment support shaft 25 , and the macro adjustment support shaft 25 can extend out of the support rod 22 along the axial direction of the support rod 22 .

[0039] In this embodiment, when the placement surface is not a plane and has a height difference, this problem can be overcome by micro-adjusting the extension of the support shaft 25, thereby further ensuring the stability of the small generator.

[0040] The length adaptation adjustment structure 15 includes a through shaft 26 fixedly connected to the power generation frame 12, the tail 14 is connected to a sliding shaft 27, the sliding shaft 27 is slidingly connected to the through shaft 26, an anti-rotation plate 28 is provided on the sliding shaft 27, and a sliding groove 29 is provided in the through shaft 26 and is slidingly connected to the anti-rotation plate 28, a screw shaft 30 is rotatably arranged in the power generation frame 12, and the screw shaft 30 extends into the sliding shaft 27 and is screwed thereto.

[0041] The length adaptation adjustment structure 15 includes a through shaft 26 fixedly connected to the power generation frame 12, the tail 14 is connected to a sliding shaft 27, the sliding shaft 27 is slidingly connected to the through shaft 26, a plurality of snap-in holes 31 are provided on the through shaft 26, a snap-in rod 32 is provided in the sliding shaft 27, the snap-in rod 32 is connected to the elastic member provided in the sliding shaft 27, and the snap-in rod 32 can extend into each snap-in hole 31.

[0042] In this embodiment, the tail 14 has two extension mechanisms: one uses a snap-on rod 32 that snaps into different snap-on holes 31 to adjust the distance between the tail 14 and the generator assembly. The other uses a screw shaft 30 that connects to the generator assembly or another internal power source to rotate, thereby screwing the tail 14 outward. A support piece 33 is detachably connected to the bottom of the bracket tube 10, and the wind turbine 13 is detachably connected to the generator frame 12.

[0043] In this embodiment, the support piece 33 provides a larger support surface to make it more stable. When not in use, the support piece 33 and the wind impeller 13 can be removed to further facilitate disassembly.

[0044] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
