Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a wind power generation blade stabilizing device. Background Art

[0002] A wind turbine is a device that converts wind energy into electrical energy. It primarily consists of blades, a generator, mechanical components, and electrical components. Depending on the axis of rotation, wind turbines are categorized into two main types: horizontal-axis wind turbines and vertical-axis wind turbines. Horizontal-axis wind turbines currently dominate the market.

[0003] During the transportation of wind turbine blades, in order to improve the stability of the blades, it is usually necessary to place the root of the blade on a bracket. However, traditional brackets are mostly of ordinary structural design, which only provide simple support for the blades. The tip of the blade is flat and the root of the blade is mostly cylindrical, which may cause the root of the blade to shift or shake during transportation. This is not only not conducive to the transportation of the blades, but also increases actual safety hazards. Utility Model Content

[0008] As a further optimized solution of the present invention, the limiting hole coincides with the axis of the blade.

[0009] As a further optimized solution of the present invention, the fastener includes a fixing block and a clamping plate. The fixing block is installed on the front side of the support. One end of the clamping plate is rotatably connected to the fixing block, and the other end of the clamping plate extends into the blade and abuts against the inner wall of the blade.

[0010] As a further optimized solution of the present invention, the splint is L-shaped, the L-shaped short arm is rotatably connected to the fixed block, the L-shaped long arm rotates to the inside of the blade, and the inner right-angled side of the L-shaped long arm fits against the inner wall of the blade.

[0011] As a further optimized solution of the present invention, an anti-slip strip is installed on the inner right-angled edge of the L-shaped long arm of the splint, and the anti-slip strip fits tightly against the inner wall of the root opening of the blade.

[0012] As a further optimized solution of the present invention, an anti-slip corner code is installed at the inner right angle of the splint, and the two right-angled sides of the anti-slip corner code are respectively in contact with the front surface of the support and the inner wall of the limiting hole.

[0013] The wind turbine blade stabilization device proposed in this utility model has the following beneficial effects:

[0027] See also Figure 1-Figure 5 A wind turbine blade stabilization device is mainly suitable for the stable transportation of wind turbine blades during production and installation. It specifically includes a base 1 and a support 2. The support 2 is installed on the base 1. A positioning groove 3 is formed on the top of the support 2 to match the root of the blade 4. A fastener 5 is installed on the support 2. The root of the blade 4 is plugged into the positioning groove 3 and fixed to the support 2 through the fastener 5.

[0028] The fastener 5 can be a locking member such as a bolt, pin, buckle, or snap in the prior art, which can insert the blade 4 into the root of the positioning groove 3 and fix it to the support 2;

[0029] Specifically, the root of the blade 4 is cylindrical and a flange plate is installed on the end surface. The cross section of the positioning groove 3 is T-shaped and is adapted to the root of the blade 4 and the flange plate. The top and sides of the positioning groove 3 are open, so that the root of the blade 4 can be inserted into the positioning groove 3 from top to bottom. Combined with the T-shaped structural design, the root of the blade 4 can be tightly combined with the support 2, thereby improving the stability of the root of the blade 4;

[0030] Furthermore, a limiting hole 6 is provided on the front of the support 2, the limiting hole 6 is connected to the positioning groove 3, and the number of fasteners 5 is multiple and evenly distributed along the circumference of the outer edge of the limiting hole 6. The multi-point distribution of the fasteners 5 can achieve multi-point fixation of the root of the blade 4, which is conducive to improving the placement stability of the blade 4;

[0031] Furthermore, the limiting hole 6 coincides with the axis of the blade 4, so that the fasteners 5 distributed at multiple points can evenly lock the root of the blade 4;

[0032] Specifically, the fastener 5 includes a fixing block 51 and a clamping plate 52. The fixing block 51 is mounted on the front surface of the support 2 and arranged circumferentially along the outer periphery of the limiting hole 6. One end of the clamping plate 52 is rotatably connected to the fixing block 51, and the other end of the clamping plate 52 extends into the blade 4 and abuts against the inner wall of the blade 4.

[0033] The clamping plate 52 is rotatably connected to the fixing block 51 via a rotating shaft. The rotating shaft is preferably a damping rotating shaft. The friction force is used to enable the clamping plate 52 to be tightly attached to the inner wall of the root of the blade 4, thereby playing a reinforcing role.

[0034] It should be noted that, according to different actual needs, a torsion spring or a buckle can be installed on the rotating shaft to use the reaction force of the spring to make the clamping plate 52 close to the inner wall of the blade 4, or a bolt can be used to fix the rotated clamping plate 52 to the support 2.

[0035] Furthermore, the clamping plate 52 is L-shaped, the short arm of the L-shaped is rotatably connected to the fixed block 51, the long arm of the L-shaped is rotated to the inside of the blade 4, and the inner right-angled side of the long arm of the L-shaped is in contact with the inner wall of the blade 4;

[0036] Furthermore, an anti-slip strip 53 is installed on the inner right-angled side of the L-shaped long arm of the clamping plate 52. The anti-slip strip 53 is tightly fitted with the inner wall of the root opening of the blade 4. The anti-slip strip 53 has strong friction and is preferably made of rubber. The side of the anti-slip strip 53 away from the clamping plate 52 has anti-slip teeth, which is conducive to increasing the friction between the clamping plate 52 and the inner wall of the blade 4, thereby preventing the blade 4 from deflecting or shaking.

[0037] Furthermore, an anti-slip angle code 54 is installed at the inner right angle of the clamping plate 52. The two right-angled sides of the anti-slip angle code 54 respectively fit the front surface of the support 2 and the inner wall of the limiting hole 6, so that the clamping plate 52 can be engaged with the opening of the limiting hole 6, thereby improving the fastening degree of the fastener 5 to the blade 4.

[0038] In summary, the wind turbine blade stabilizing device proposed in the present invention opens a positioning groove 3 on the support 2 and utilizes the T-shaped cross-section design of the positioning groove 3 to enable the support 2 to be combined with the root of the blade 4, so that the root of the blade 4 is tightly assembled with the support 2, and then the long arm of the splint 52 is rotated into the blade 4, so that the anti-slip strip 53 is tightly attached to the inner wall of the blade 4, and the anti-slip angle code 54 is engaged with the opening of the limiting hole 6, thereby reinforcing the blade 4, and utilizing the circumferential distribution of multiple fasteners 5 to achieve multi-point reinforcement of the root of the blade 4, which can prevent the root of the blade 4 from shaking or deflecting during transportation, is beneficial to the actual transportation of the blade 4, and also helps to reduce safety hazards.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
