Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically to a support structure for wind turbine maintenance. Background Technology

[0002] With the continuous development of society and the advancement of science and technology, the concept of energy conservation and environmental protection has become increasingly popular, and wind power generation, as a means of clean energy, has also seen large-scale development. As the main component of a wind turbine, wind turbine blades may malfunction during use, requiring the use of maintenance brackets to clamp and secure them for repairs.

[0003] A search revealed that in patent publication number CN220463793U, a high-strength wind turbine blade repair bracket, it was proposed that "compared with existing blade repair brackets, the upper clamping structure of this blade repair bracket is achieved by driving the clamping plate through the second hydraulic telescopic rod, rather than by manually rotating the screw. The second hydraulic telescopic rod is controlled by the control panel, eliminating the need for manual rotation of the screw. This greatly improves the ease of use of the device and significantly increases the clamping force, making it less likely for the blade to shake, thus greatly improving the practical performance of the repair bracket."

[0004] However, the above solution still has certain shortcomings in practical use. In this technical solution, the designers used a hydraulic telescopic rod to achieve the clamping function of the blade. However, after the clamping action is completed, the blade cannot be rotated, which brings inconvenience when performing multi-angle maintenance on the blade. In order to inspect and maintain the blade from different angles, the staff have to frequently disassemble and reassemble the blade. This frequent disassembly and reassembly not only increases the complexity of maintenance but also greatly reduces the efficiency of maintenance work, making the entire blade maintenance process extremely cumbersome.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model discloses a support structure for wind turbine maintenance, including a maintenance platform 1. The top of the maintenance platform 1 is provided with a fixed support structure 2 and a movable support structure 4. The outer sides of the fixed support structure 2 and the movable support structure 4 are respectively provided with a first clamping mechanism 5 and a second clamping mechanism 6.

[0024] A control panel 7 is fixedly installed on the outer edge of the maintenance platform 1. The control panel 7 is electrically connected to the fixed support structure 2, the first clamping mechanism 5, and the second clamping mechanism 6.

[0025] The fixed support structure 2 includes a mounting plate 201, with a mounting groove 202 inside the mounting plate 201. A servo motor 203 is fixedly installed inside the mounting groove 202. The output shaft of the servo motor 203 is fixedly connected to a transmission disk 205. A turntable 204 is rotatably connected to the outside of the mounting plate 201. The turntable 204 and the transmission disk 205 are connected by a transmission belt.

[0026] The movable lifting structure 4 includes a movable plate 401, and a connecting bearing 403 is rotatably connected to the outer side of the movable plate 401. A second clamping mechanism 6 is installed at the center of the connecting bearing 403.

[0027] The first clamping mechanism 5 and the second clamping mechanism 6 are placed opposite each other, and the first clamping mechanism 5 and the second clamping mechanism 6 have the same structure. The second clamping mechanism 6 includes an outer box 601. A hydraulic telescopic rod 602 is fixedly installed inside the outer box 601. An upper clamping claw 603 is fixedly connected to the movable end of the hydraulic telescopic rod 602. The upper clamping claw 603 extends to the top of the outer box 601. A lower clamping claw 604 is fixedly installed on the outer box 601.

[0028] By setting up a fixed lifting structure 2, a movable lifting structure 4, a first clamping mechanism 5, and a second clamping mechanism 6, the fixed lifting structure 2 and the movable lifting structure 4 can respectively drive the two sets of clamping mechanisms to contact the blade to be repaired. In addition, the two sets of clamping mechanisms can clamp the blade to be repaired. The clamped blade can be flexibly adjusted at the angle on the maintenance platform 1, which provides great convenience for maintenance personnel, enabling them to easily perform all-round and multi-angle maintenance operations on the wind turbine blades. This structural design significantly improves the convenience and efficiency of maintenance work, making the entire maintenance process more efficient and precise.

[0029] Specifically, a locking gear ring 208 is fixedly installed on the outer side of the output shaft of the servo motor 203, an electric push rod 206 is fixedly installed on the inner wall of the mounting groove 202, and a locking rack 207 is fixedly installed on the movable end of the electric push rod 206.

[0030] In this implementation scheme, when the servo motor 203 is working, it drives the locking gear ring 208 to rotate together. At this time, the electric push rod 206 is activated, pushing the locking rack 207 towards the locking gear ring 208 until the locking rack 207 engages with the locking gear ring 208, thereby locking the output shaft of the servo motor 203 and ensuring that the turntable 204 remains stable when needed, improving the safety and stability during maintenance. Furthermore, both locking and unlocking operations can be easily performed through the control panel 7, further enhancing the ease of operation.

[0031] Specifically, a slider 402 is fixedly installed at the bottom of the movable plate 401, and a linear guide rail 3 is provided at the top of the maintenance platform 1. The slider 402 is connected to the linear guide rail 3.

[0032] In this embodiment, the design of the slider 402 of the movable lifting structure 4 and the linear guide rail 3 not only ensures the stable sliding of the movable lifting structure 4 on the maintenance platform 1, but also allows the second clamping mechanism 6 to be easily adjusted in position as needed to adapt to the maintenance requirements of blades of different sizes and shapes.

[0033] Specifically, anti-slip pads 605 are provided at the bends of the upper clamping claw 603 and the lower clamping claw 604, and the anti-slip pads 605 are soft silicone grease pads.

[0034] In this implementation scheme, the anti-slip pad 605 enhances the friction between the upper clamping jaws 603 and lower clamping jaws 604 and the clamped blade, effectively preventing safety accidents caused by accidental slippage or rotation of the blade during maintenance. It also prevents the blade from slipping off between the clamping jaws 603 and lower clamping jaws 604 during rotation, further improving the safety of maintenance work. Simultaneously, the soft silicone grease material has good elasticity and wear resistance, maintaining good clamping performance and service life during prolonged use.

[0035] When it is necessary to repair the wind turbine blades, the servo motor 203 can be started. The output shaft of the servo motor 203 drives the transmission disk 205 to rotate. The transmission disk 205 drives the turntable 204 to rotate through the transmission belt. The turntable 204 then drives the entire fixed support structure 2 to adjust the angle, so that the first clamping mechanism 5 can flexibly align with the position of the blade to be repaired.

[0036] Meanwhile, the movable lifting structure 4 can slide on the linear guide rail 3 via the slider 402 to adjust the relative position of the second clamping mechanism 6 and the blade to be repaired.

[0037] After the two sets of clamping mechanisms are aligned with the blade, the hydraulic telescopic rod 602 in the first clamping mechanism 5 and the second clamping mechanism 6 can be activated via the control panel 7. The movable end of the hydraulic telescopic rod 602 pushes the upper clamping claw 603 downward until the upper clamping claw 603 and the lower clamping claw 604 jointly clamp the blade. The anti-slip pad 605 ensures the stability of the blade during clamping and prevents it from slipping or shaking.

[0038] After clamping, maintenance personnel can control the servo motor 203 and electric push rod 206 via the control panel 7 to achieve flexible angle adjustment of the blades. The servo motor 203 can drive the fixed support structure 2 to rotate, while the electric push rod 206 can lock and release the turntable 204 through the cooperation of the locking rack 207 and the locking ring 208, thereby fixing the blade angle when needed for maintenance operations.

[0039] In summary, this wind turbine maintenance support structure, by setting up a fixed lifting structure 2, a movable lifting structure 4, a first clamping mechanism 5, and a second clamping mechanism 6, allows the fixed lifting structure 2 and the movable lifting structure 4 to drive the two sets of clamping mechanisms to contact the blades to be repaired. The two sets of clamping mechanisms then clamp the blades, allowing for flexible angle adjustment on the maintenance platform 1. This provides great convenience for maintenance personnel, enabling them to easily perform comprehensive and multi-angle maintenance operations on the wind turbine blades. This structural design significantly improves the convenience and efficiency of maintenance work, making the entire maintenance process more efficient and precise.

[0040] It should be noted that the specific models and specifications of the servo motor 203, electric push rod 206, linear guide rail 3, hydraulic telescopic rod 602 and control panel 7 in the support structure for wind turbine maintenance need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0041] Furthermore, the power supply and operating principle of the servo motor 203, electric push rod 206, linear guide rail 3, hydraulic telescopic rod 602, and control panel 7 in the fan maintenance support structure are clear to those skilled in the art and will not be described in detail here.
