DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0030] like Figure 1 The supporting device for a wind turbine generator which is convenient for improving stability is the best embodiment of the present invention. The supporting device comprises a supporting column 1, a bearing plate 3, a wind turbine generator body 5, a mounting mechanism 6, an adjusting mechanism 7 and a lifting mechanism.

[0031] The mounting mechanism 6 is arranged on the connecting platform 4, and the mounting mechanism 6 includes a support member 601, a long groove 602, an adjusting rod 603, a connecting strip 604, a connecting plate 605, a limiting strip 606 and a protective pad 607, wherein the support member 601 is symmetrically inlaid and connected to the upper end of the connecting platform 4, and the inner end of the support member 601 is matched with the lower end of the wind turbine body 5.

[0032] The adjusting mechanism 7 is arranged at the upper end of the top plate 2, and the adjusting mechanism 7 includes a connecting shaft 701, a worm gear 702, a worm 703, a first vertical plate 704, a first motor 705, a limiting groove 706, a limiting block 707 and a hydraulic telescopic rod 708. At the same time, the upper end of the connecting shaft 701 is fixedly connected to the lower end of the connecting platform 4, and the lower end of the connecting shaft 701 is rotatably connected to the upper end of the top plate 2.

[0033] The lifting mechanism includes a steel wire rope 10, a winding roller 11 and a limiting wheel structure. The limiting wheel structure includes a second vertical plate 8, which is symmetrically connected to the front lower end of the bearing plate 3, and the inner end of the second vertical plate 8 is rotatably connected to a pulley 9, on which a steel wire rope 10 is placed, and the rear upper end of the steel wire rope 10 is fixedly connected to the front upper end of the top plate 2, and the steel wire rope 10 is connected to the front end of the top plate 2.

[0034] The rear end of the winding roller 11 is rotatably connected to the front middle and lower end of the support column 1 , and the left side longitudinal section of the winding roller 11 is an "I"-shaped structure, and the lower end of the wire rope 10 is wound around the inner end of the winding roller 11 .

[0035] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, when the support device for a wind turbine generator that is convenient for improving stability is used, the position of the wind turbine generator body 5 is limited by a structure composed of a support member 601, a long slot 602, an adjustment rod 603, a connecting strip 604, a connecting plate 605, a limiting strip 606 and a protective pad 607. Since the outer surface of the adjustment rod 603 has a bidirectional external thread, the bidirectional external thread is symmetrically arranged with the length center of the adjustment rod 603 as the center. The lower end of the connecting strip 604 on one side is arranged in cooperation with the bidirectional external thread on one side, and the connecting strip 604 is nested and connected inside the long slot 602. When the adjustment rod 603 is rotated, under the limiting action of the long slot 602, the connecting strips 604 on both sides move toward each other or away from each other. The inner wall of the protective pad 607 is a concave-convex structure and is embedded in the inner wall of the limiting strip 606. The left longitudinal section of the front and rear groups of limit strips 606 forms a circular ring structure, and the inner end diameter of the protective pad 607 provided inside the limit strip 606 is equal to the middle diameter of the wind turbine body 5. The limit strip 606 can slide relative to the long slot 602 by adjusting the adjusting rod 603, thereby realizing the opening and closing clamping operation at the middle position of the wind turbine body 5.

[0036] When the wind turbine body 5 is installed relative to the connecting platform 4, the wind turbine body 5 is placed on the upper end of the connecting platform 4, the lower end of the wind turbine body 5 is fitted on the supporting member 601 symmetrically arranged on the left and right sides, the adjusting rod 603 is rotated to rotate inside the supporting member 601, the adjusting rod 603 symmetrically nested and connected inside the long slot 602 slides inwardly, the connecting strip 604 pushes the front and rear connecting plates 605 to move inwardly respectively, so that the limiting strips 606 symmetrically arranged on the front and rear sides are close to each other, until the inner end of the protective pad 607 is tightly against the front and rear side walls of the wind turbine body 5, and the friction between the protective pad 607 and the wind turbine body 5 is increased by the concave-convex structure of the inner wall of the protective pad 607, so as to facilitate the position of the wind turbine body 5. For disassembly, the adjusting rod 603 is rotated in the opposite direction, so that the clamping part no longer clamps the wind turbine body 5, and then the wind turbine body 5 can be easily disassembled from the connecting platform 4.

[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, since the top plate 2 forms a lifting structure with the supporting plate 3 through the wire rope 10, the limit rod 14 is snap-connected in the limit hole 17 on the lower side, and the limit hole 17 is opened at an equal angle inside the connecting plate 13. The rear end of the limit rod 14 is snap-connected at the fixing hole of the mounting plate 12. The limit rod 14 forms a telescopic structure with the mounting plate 12 through the mounting strip 15. Therefore, when the connecting shaft 701 drives the connecting platform 4 to rotate and the connecting platform 4 is moved away from the upper end of the supporting plate 3, the mounting strip 15 is pulled forward to allow the limit rod 14 to disengage from the inside of the limit hole 17, and the connecting plate 13 is rotated to drive the winding roller 11 to rotate on the mounting plate 12 and the support column 1, so that the winding roller 11 can release the wire rope 10, and the wire rope 10 can move at the inner end of the pulley 9, so that the top plate 2 slides downward on the support column 1.

[0038] The connecting platform 4 is driven down by the top plate 2 to adjust the distance between the wind turbine body 5 and the ground. When the wind turbine body 5 is adjusted to a suitable height, the mounting strip 15 is pulled to allow the limiting rod 14 to be engaged and connected in the limiting hole 17 at the corresponding position and inside the front lower end of the mounting plate 12, and the waterproof spring 16 pulls the mounting strip 15 to fit tightly against the front wall of the mounting plate 12, thereby completing the adjustment of the wind turbine body 5 along the height direction of the support column 1.

[0039] In actual design, the bearing plate 3 is usually fixed at the middle position of the top of the support column 1, and the lifting mechanism is usually set on the side of the support mechanism, so the wind turbine body 5 set on the lifting mechanism usually needs to be transported and fixed to the middle position of the top of the support column 1, that is, the position of the bearing plate 3. Therefore, it is necessary to design an adjustment structure accordingly to achieve the position adjustment of the wind turbine body 5 on the bearing plane of the bearing plate 3, that is, to achieve the rotation and transportation of the wind turbine body 5.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the positional relationship between the connecting platform 4 and the carrying plate 3 can be adjusted by the structure composed of the connecting shaft 701, the worm wheel 702, the worm 703, the first vertical plate 704, the first motor 705, the limiting groove 706, the limiting block 707 and the hydraulic telescopic rod 708. Since the rear end of the worm wheel 702 is meshed with the worm 703, the vertical section of the limiting block 707 is a "convex" structure, the upper end of the limiting block 707 is engaged and connected to the inside of the limiting groove 706, and the limiting groove 706, which is a "concave" structure in the vertical section, is embedded and connected to the front lower end of the connecting platform 4. The connecting platform 4 is a rotating structure on the upper side of the carrying plate 3 through the worm wheel 702 and the worm 703.

[0041] Therefore, when the connecting platform 4 rises to the upper side of the carrying plate 3, the two first vertical plates 704 are symmetrically arranged on the top plate 2, and the worm 703 is rotatably arranged between the two first vertical plates 704. The first motor 705 drives the worm 703 to rotate upward, and the worm 703 meshes with the worm wheel 702 when rotating, and drives the connecting shaft 701 to rotate at the upper end of the top plate 2 through the worm wheel 702, and the connecting shaft 701 rotates away from the right end of the connecting shaft 701 to the upper end of the carrying plate 3, and the hydraulic telescopic rod 708 drives the limit block 707 to rise when working, so that the limit block 707 with a "convex"-shaped structure when the longitudinal section is cut is engaged and connected to the inside of the limit groove 706 with a "concave"-shaped structure when the longitudinal section is cut. The position of the connecting platform 4 on the supporting plate 3 is limited by the worm 703 , the limiting groove 706 and the limiting block 707 , thereby limiting and adjusting the position of the connecting platform 4 relative to the supporting plate 3 , thereby improving the stability of the wind turbine body 5 on the top of the supporting column 1 .

[0042] In this way, through the coordinated design of the mounting mechanism 6, the limit strip 606 and the long groove 602, the outer surface of the adjusting rod 603 is a bidirectional external thread, so that the inner walls of the two sets of protective pads 607 are tightly against the outer wall of the wind turbine body 5, thereby facilitating the limitation of the position of the wind turbine body 5, and the limitation is easy to adjust, thereby facilitating the disassembly of the wind turbine body 5.

[0043] Through the coordinated design of the adjustment mechanism 7, the connection platform 4 and the bearing plate 3, when the worm 703 rotates, the connection shaft 701 is driven to rotate through the worm wheel 702, and the connection shaft 701 rotates the connection platform 4 to the upper end of the bearing plate 3, and the upper end of the limit block 707 is engaged and connected in the limit groove 706. The hydraulic telescopic rod 708 drives the limit block 707 to rise, and the upper end of the limit block 707 is engaged and connected in the limit groove 706 to further effectively limit the position of the connection platform 4, which can improve the stability of the wind turbine body 5 on the top of the support column 1.

[0044] Through the coordinated design of the steel wire rope 10 and the winding roller 11, the top plate 2 and the bearing plate 3, when the connecting plate 13 rotates, the winding roller 11 releases the steel wire rope 10, driving the top plate 2 to slide downward along the support column 1, and the top plate 2 drives the wind turbine body 5 to descend. Through the structural design of the limit rod 14 and the mounting plate 12, after the position of the wind turbine body 5 is adjusted, the limit rod 14 is tightly connected to the limit hole 17 at the corresponding position and the fixing hole of the mounting plate 12 through the waterproof spring 16, so as to facilitate the lowering of the height of the wind turbine body 5 for inspection and maintenance of the wind turbine body 5.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
