Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and more specifically, to an adjustable support device for wind turbine maintenance. Background Technology

[0002] Wind turbines are key equipment that efficiently converts wind energy into electrical energy. They have a wide range of applications, including centralized wind farms that supply power to the grid on a large scale, and distributed power generation projects in remote areas that meet the electricity needs of off-grid users. They play an extremely important role in the global energy transition and are one of the core pieces of equipment for achieving sustainable energy development. The rotor of a wind turbine is a core component, consisting of blades and a hub. The blades are mostly made of composite materials such as glass fiber and carbon fiber, and have a unique streamlined shape. With their lightweight and high-strength characteristics, they efficiently capture wind energy and convert it into mechanical energy that drives the rotor to rotate. The rotor requires a support device for maintenance.

[0003] A search revealed Chinese patent application number CN202122877401.3, which discloses a support fixture for wind turbine rotor maintenance. The fixture includes a maintenance platform with a sliding groove on the top. The inner wall of the sliding groove is provided with a position adjustment mechanism. The surface of the position adjustment mechanism is threadedly connected to a first moving block and a second moving block. The top of the first moving block and the second moving block are fixedly connected to mounting plates. The opposite surfaces of the two mounting plates are fixedly connected to fixed seats. An angle adjustment mechanism and a fixing mechanism are respectively installed on the opposite surfaces of the two mounting plates.

[0004] Although the aforementioned patent achieves the effect of conveniently rotating the generator rotor by setting up a position adjustment mechanism, mounting plate, fixed seat, connecting rod, limiting tube, and angle adjustment mechanism, with the threads on the inner walls of the first and second moving blocks being opposite, and the first threaded rod of the position adjustment mechanism rotating, causing the first and second moving blocks to drive the top mounting plate to move in opposite directions, driving the connecting rod and limiting tube to align with both ends of the generator rotor central shaft, clamping the generator rotor central shaft, and fixing the position of the generator rotor central shaft, and rotating the connecting shaft and connecting rod through the angle adjustment mechanism, thereby driving the generator rotor to rotate, the following shortcomings still exist in use: the device cannot be flexibly and precisely adjusted according to changes in the size of the rotor central shaft, has poor compatibility, and limits its scope of use and application efficiency.

[0005] Therefore, there is an urgent need for an adjustable support device for wind turbine maintenance to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

It solves the problem in the prior art that the device cannot make flexible and precise adjustments according to the changes in the size of the rotor central shaft, resulting in poor versatility and limiting its application range and performance.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] like Figure 1-5As shown, this embodiment proposes an adjustable support device for wind turbine maintenance, including a base 1. Symmetrically distributed movable blocks 4 are slidably connected to the top wall of the base 1. A mounting plate 5 is fixedly connected to the top wall of the movable blocks 4. A fixed seat 6 is fixedly connected to the outer wall of the mounting plate 5. A connecting rod 7 is rotatably connected to the outer wall of the fixed seat 6. A worm gear 8 is fixedly connected to the outer wall of the connecting rod 7 on the right side. The device also includes:

[0027] The drive assembly includes a threaded sleeve 12 fixedly connected to the outer wall of the connecting rod 7. A drive rotating sleeve 13 is threadedly connected to the outer wall of the threaded sleeve 12. A drive fixed sleeve 14 is rotatably connected to the outer wall of the drive rotating sleeve 13. A uniformly distributed drive block 15 is fixedly connected to the outer wall of the drive fixed sleeve 14. A linkage block 16 is connected to the rotating wheel of the drive block 15. Rotating the drive rotating sleeve 13 causes the drive rotating sleeve 13 to move along the direction of the connecting rod 7 through the threaded engagement between the drive rotating sleeve 13 and the threaded sleeve 12, thereby driving the drive fixed sleeve 14 to move, and driving the linkage block 16 to move through the drive block 15.

[0028] The driven component is located on the outer wall of the connecting rod 7.

[0029] like Figure 3-5 As shown, in a preferred embodiment, based on the above method, the driven component further includes a positioning plate 18 fixedly connected to the outer wall of the connecting rod 7. The outer wall of the positioning plate 18 is provided with uniformly distributed sliding grooves 19. A slider 17 is slidably connected to the inner wall of the sliding groove 19, and the slider 17 is rotatably connected to the linkage block 16. A limit plate 20 is fixedly connected to the outer wall of the slider 17. The slider 17 is moved along the sliding groove 19 by the movement and compression of the linkage block 16, thereby driving the limit plate 20 to move. By synchronously adjusting the distance between the limit plates 20, the central shaft of rotors of different sizes can be adapted, which has high flexibility.

[0030] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a connecting seat 9 is fixedly connected to the outer wall of the right mounting plate 5, and a drive motor B10 is fixedly connected to the outer wall of the connecting seat 9. A worm gear 11 is fixedly connected to the output end of the drive motor B10, and the worm gear 11 is rotatably connected to the connecting seat 9. The outer wall of the worm gear 11 is meshed with the outer wall of the worm wheel 8. When the drive motor B10 is started, its output end drives the worm gear 11 to rotate. The worm gear 11 meshes with the worm wheel 8, thereby driving the connecting rod 7 to rotate, thereby driving the rotor between the limiting plates 20 to rotate, and realizing the synchronous rotation of the connecting rod 7 on the other side through the rotor.

[0031] like Figure 1As shown, in a preferred embodiment, based on the above method, a drive motor A2 is fixedly connected to the outer wall of the base 1, and a bidirectional screw 3 is fixedly connected to the output end of the drive motor A2. The bidirectional screw 3 is rotatably connected to the base 1, and the outer wall of the bidirectional screw 3 is threadedly connected to the moving block 4. When the drive motor A2 is started, its output end drives the bidirectional screw 3 to rotate. Since the bidirectional screw 3 is threadedly connected to the moving block 4, the moving block 4 will slide along the guide rail 21 on the top wall of the base 1, realizing the relative or opposite movement of the two moving blocks 4, thereby adjusting the distance between the mounting plates 5, which can adapt to wind turbine components of different widths.

[0032] like Figure 1 As shown, in a preferred embodiment, based on the above method, the base 1 is further provided with a guide rail 21 fixedly connected to the top wall, a guide block 22 slidably connected to the outer wall of the guide rail 21, an electric telescopic rod 23 fixedly connected to the top wall of the guide block 22, and a bracket 24 fixedly connected to the output end of the electric telescopic rod 23. The electric telescopic rod 23 can extend and retract as needed, driving the bracket 24 to rise and fall, so as to adapt to wind turbine components of different heights and provide support for them.

[0033] Specifically, when using this adjustable wind turbine maintenance support device: rotating the drive sleeve 13 causes the drive sleeve 13 to move along the direction of the connecting rod 7 through the threaded engagement between the drive sleeve 13 and the threaded sleeve 12, thereby driving the drive fixed sleeve 14 to move, and driving the linkage block 16 to move through the drive block 15, thereby squeezing and driving the slider 17 to move along the slide groove 19, thereby driving the limit plate 20 to move. By synchronously adjusting the distance between the limit plates 20, the device can adapt to the central shaft of rotors of different sizes, with high flexibility.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
