Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly tools, in particular to a disassembly and assembly tool for a wind speed measurement bracket of a wind turbine generator set. Background Art

[0002] On the top of the nacelle of a large wind turbine generator set (taking the Goldwind 2.X series of wind turbine generator sets as an example), there are often supporting devices installed, including a wind vane, a wind direction sensor, and a fence for protecting the safety of workers. At present, some wind vanes and wind direction sensors are directly installed on the fence, and the wind speed measurement bracket of the wind vane (wind direction sensor) is fixed on the fence through a plurality of support bolts.

[0003] During the maintenance of the wind vane (wind direction sensor), it is necessary to remove a plurality of support bolts one after another. When the last support bolt is removed, due to the unstable center of gravity of the wind vane, the wind speed measurement bracket will rotate back and forth with the last support bolt as the center of the circle. When it rotates backward to the outside of the guardrail, it will hit the tail of the nacelle, causing damage and leakage of rain in the tail of the nacelle; when it rotates forward to the inside of the guardrail, it may hit the workers. Therefore, when disassembling the wind speed measurement bracket, two people must cooperate with each other. One person holds the wind speed measurement bracket and the fence with both hands, and the other person removes the bolts. However, the wind vane is not only heavy but also much higher than the height of ordinary people. If the wind speed measurement bracket accidentally topples and rotates, it will also cause finger shearing injuries to the workers. In view of the above problems, we propose a disassembly and assembly tool for the wind speed measurement bracket. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the wind speed measurement bracket on the wind turbine generator set is not easy to disassemble and assemble, and to propose a disassembly and assembly tool for the wind speed measurement bracket of a wind turbine generator set.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A disassembly and assembly tool for a wind speed measurement bracket of a wind turbine generator set includes a first sleeve fixedly connected to the fence. A support arm and a second sleeve are sequentially arranged at the bottom of the first sleeve. Both ends of the support arm are respectively hinged to the first sleeve and the second sleeve, so that the first sleeve and the fence rotate towards the inside of the wind speed measurement bracket, and the second sleeve is fixedly installed on the wind speed measurement bracket.

[0007] Further, a hinge seat is arranged at the front end of the second sleeve, and the support arm is rotationally connected to the second sleeve through the hinge seat.

[0008] Further, a sliding seat is arranged at the front end of the first sleeve, and the support arm is rotationally connected to the first sleeve through the sliding seat.

[0009] Further, the sliding seat includes an oblong chute opened in the vertical direction and a slider located in the oblong chute. The support arm is rotatably connected to the sliding seat through the slider.

[0010] Further, there are two support arms, and the two support arms are arranged in a V shape.

[0011] Further, the first sleeve includes a U-shaped groove block sleeved on the fence and a cover plate hinged to the U-shaped groove block.

[0012] Further, one end of the U-shaped groove block is hinged to the cover plate, and the other end is plugged with the cover plate through a plug structure.

[0013] Compared with the prior art, the present utility model provides a disassembly and assembly tool for a wind turbine anemometer support, having the following beneficial effects:

[0014] When in use, the disassembly and assembly tool for a wind turbine anemometer support of the present utility model is installed on an existing anemometer support. When the anemometer support needs to be disassembled, first remove the support bolts. When the last support bolt is about to be removed, the staff only needs to support the forward tilting of the anemometer support. The last support bolt cooperates with the present tool to support the tilted anemometer support, and then the wind vane can be repaired. The operation is simple and the safety is high.

[0015] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent specification; and to some extent, based on the study of the following text, they will be obvious to those skilled in the art; or, they can be taught from the practice of the present utility model.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figure 1-7 , a disassembly and assembly tool for a wind measurement bracket of a wind turbine of the present utility model includes a first sleeve 1 fixedly connected to the fence 6. A support arm 2 and a second sleeve 3 are sequentially installed at the bottom of the first sleeve 1. Both ends of the support arm 2 are respectively hinged to the first sleeve 1 and the second sleeve 3, so that the first sleeve 1 and the fence 6 rotate towards the inside of the wind measurement bracket 5, and the second sleeve 3 is fixedly installed on the wind measurement bracket 5.

[0027] Since wind turbines need to be installed in areas with rich wind resources, there is often strong wind at the top of the nacelle. Such high-altitude operations of the staff are accompanied by the shaking of the nacelle, which has a certain impact on the work of the staff itself. Under the action of strong wind, the wind vane or wind direction instrument will swing uncertainly, and it is impossible to accurately control the dumping direction of the wind measurement bracket during disassembly.

[0028] The first sleeve 1 is located above the bracket bolt 7, and the second sleeve 3 is located below the bracket bolt 7. Remove the bracket bolt 7. When only one bracket bolt 7 remains, loosen this bracket bolt 7. The wind measurement bracket 5 can only rotate forward under the restraint of this tooling, preventing the situation that the wind measurement bracket 5 rotates backward and damages the nacelle. The staff only needs to support the wind measurement bracket 5 in front to prevent the situation that the staff may be sheared when manually holding the wind measurement bracket 5 and the fence 6, reducing the disassembly difficulty and improving safety.

[0029] The front end of the second sleeve 3 is fixedly connected with a hinge seat 301. The support arm 2 is rotatably connected to the second sleeve 3 through the hinge seat 301. When the support arm 2 rotates backward, it is blocked by the second sleeve 3, so that the support arm 2 can only rotate forward. Through the cooperation of the support arm 2 and the first sleeve 1, the wind measurement bracket 5 can only rotate forward, thus preventing the wind measurement bracket 5 from rotating backward under the action of strong wind.

[0030] A sliding seat 4 is fixedly connected to the front end of the first sleeve 1. The support arm 2 is rotatably connected to the first sleeve 1 through the sliding seat 4. Under the connection action of the sliding seat 4, while the top of the support arm 2 rotates around the hinge seat 301, the connection point between the support arm 2 and the sliding seat 4 slides simultaneously, so as to cooperate with the wind measurement bracket 5 and the first sleeve 1 to rotate around the last bracket bolt 7.

[0031] The sliding seat 4 includes an oblong chute 401 opened in the vertical direction and a slider 402 located in the oblong chute 401. The support arm 2 is rotatably connected to the sliding seat 4 through the slider 402. When the top of the support arm 2 rotates around the hinge seat 301 and the wind measurement bracket 5 and the first sleeve 1 rotate around the last bracket bolt 7, the slider 402 slides in the oblong chute 401.

[0032] Specifically, as Figure 7 shown, taking the second bracket bolt 7 from top to bottom as the last bolt as an example, the center line of the oblong chute 401 is the center line 803, and the center line 803 is also the moving track of the center of the slider 402. The support arm 2 rotates with the hinge seat 301 as the center, and the rotation track is circle one 801. The first sleeve 1, the wind measurement bracket 5, and the center line 803 rotate with the bracket bolt 7 as the center, and the rotation track is circle two 802.

[0033] The magnitude of the angle by which the wind measurement bracket 5 rotates forward depends on the positions of the bracket bolt 7 and the first sleeve 1 on the wind measurement bracket 5, as well as the lengths of the support arm 2 and the oblong chute 401 in the vertical direction.

[0034] During manufacturing, it is possible to first determine the positions of circle one 801 and the bracket bolt 7, and then determine the rotation angle of the center line 803, that is, the rotation angle of the wind measurement bracket 5. Taking the wind measurement bracket 5 rotating 90 degrees as an example, after rotation, the wind measurement bracket 5 is in a horizontal state. Therefore, a circle two 802 can be drawn with the distance from the intersection of the horizontal center line 803 and circle one 801 to the bracket bolt 7 as the radius. Then, the intersection of circle one and the center line 803 in the vertical state is the initial position of the slider 402, and the intersection of circle one and the center line 803 in the horizontal state is the position of the slider 402 after rotation, so as to determine the length of the oblong chute 401.

[0035] When the wind measurement bracket 5 rotates forward, when it rotates to the intersection where the slider 402 moves to the horizontal state, the slider 402 is blocked by the oblong chute 401, so that the wind measurement bracket 5 can stably maintain a horizontal state. At this time, the staff can replace or repair the wind vane or wind direction instrument on the wind measurement bracket 5 without completely removing the wind measurement bracket 5.

[0036] There are two support arms 2, and the two support arms 2 are arranged in a V shape. The two support arms 2 arranged in a V shape are respectively located on the left and right sides of the anemometer support 5, and support the anemometer support 5 from the left and right sides to prevent the anemometer support 5 from swinging to the left and right sides.

[0037] The first sleeve 1 includes a U-shaped groove block 101 sleeved on the fence 6 and a cover plate 102 hinged to the U-shaped groove block 101. The inner wall size of the U-shaped groove block 101 corresponds to the outer wall size of the anemometer support 5. After the U-shaped groove block 101 is sleeved on the anemometer support 5, the cover plate 102 is covered, and the U-shaped groove block 101, the cover plate 102 and the anemometer support 5 are welded together to form a stable connection for the anemometer support 5.

[0038] One end of the U-shaped groove block 101 is hinged to the cover plate 102, and the other end is plugged with the cover plate 102 through a plug-in structure 103. After the U-shaped groove block 101 is sleeved on the anemometer support 5, the cover plate 102 is rotated and covered on the anemometer support 5, and finally the connection between the U-shaped groove block 101 and the cover plate 102 is fixed with the plug-in structure 103, which makes it easier to install the first sleeve 1 on the anemometer support 5 and is convenient for installation on the existing anemometer support 5.

[0039] The structure of the second sleeve 3 can be the same as that of the first sleeve 1, such as Figure 4 the structure obtained by rotating the first sleeve 1 in Figure 2 by 90 degrees with the opening facing backward, or it can be different, such as the structure in

[0040] Working principle: Before use, first sleeve the first sleeve 1 on the anemometer support 5, sleeve the second sleeve 3 on the fence 6, adjust the first sleeve 1 upward so that the slider 402 is located at the bottom of the oblong chute 401, and then weld and fix the first sleeve 1 and the second sleeve 3.

[0041] During use, the staff first removes the support bolts 7. When there is the last support bolt 7 left, slightly loosen the cover support bolt 7, and then the anemometer support 5 is tilted forward slowly until it reaches the horizontal state.

[0042] When it is necessary to install a wind vane or a wind direction sensor, push the side seam support 5 in the reverse direction to the vertical state, and screw on all the support bolts 7.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
