[0002] The wind turbine tower is the tower of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. The production process of wind turbine tower is generally as follows: CNC cutting machine unloads, thick plates need to be beveled, plate rolling machine rolls the plate into shape, spot welding, positioning, and confirmation before welding the inner and outer longitudinal seams. After the roundness check, if there is a problem, a second rounding is performed. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, the weld is non-destructively tested and the flatness is checked. After sandblasting and painting, the internal parts are installed and the finished product is inspected, and then it is transported to the installation site.

However, the wind tower is used as a support and energy-absorbing component of the wind turbine generator set. Therefore, a reinforcement ring is often installed on the surface of the wind tower to improve the stability of the wind tower. However, the existing reinforcement ring is too limited in use, and the position of the reinforcement ring cannot be reasonably adjusted after installation;

[0006] At the same time, under the action of strong winds, even if the wind tower is reinforced with a reinforcement ring, it will produce slight vibrations, which will affect the stability of the wind tower. Utility Model Content

When the reinforcement ring moves to the appropriate position, the twisting block is rotated in the opposite direction, which is opposite to the above description, and the pin rod will move downward and enter the corresponding pin hole to complete the adjustment of the reinforcement ring position. At the same time, the buffer mechanism can squeeze the fitting block when the wind power tower is slightly shaken, and the fitting block will drive the buffer rod and the buffer block to move to the side close to the spring. The buffer block squeezes the spring to relieve the force generated by the shaking of the wind tower and play a buffering role, thereby solving the problems in the background technology.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 , the utility model provides a technical solution:

[0031] Embodiment 1:

[0032] A wind turbine tower reinforcement device with good corrosion resistance comprises a base 1, a placement groove 2, a wind turbine tower 3 and a reinforcement ring 4, wherein the placement groove 2 is opened at the top of the base 1, the wind turbine tower 3 is located inside the placement groove 2, the reinforcement ring 4 is sleeved on the surface of the wind turbine tower 3, and two adjustment mechanisms are arranged at the bottom of the wind turbine tower 3, which can adjust the height of the reinforcement ring 4;

[0033] The buffer mechanism is fixedly arranged on the reinforcement ring 4 , and can enable the reinforcement ring 4 to buffer the vibration generated by the wind turbine tower 3 .

[0034] One implementation method of the present embodiment 1 is: the adjustment mechanism includes two first U-shaped blocks 5 fixedly connected to the bottom of the reinforcement ring 4, the inner wall of the first U-shaped block 5 is movably connected to the support rod 6 through a rotating shaft, one end of the support rod 6 is movably connected to the second U-shaped block 7 through a rotating shaft, the bottom of the second U-shaped block 7 is fixedly connected to a T-shaped block 8, and the top of the base 1 is provided with a T-shaped slot 9 used in conjunction with the T-shaped block 8.

[0035] Preferably, the adjustment mechanism further comprises a housing 10 fixedly connected to one side of the second U-shaped block 7, a threaded rod 11 is arranged on the top of the housing 10, the bottom of the threaded rod 11 penetrates into the interior of the housing 10, a moving block 12 is transmission-connected to the surface of the threaded rod 11, and two pins 13 are fixedly connected to the bottom of the moving block 12;

[0036] The top of the base 1 is provided with a pin hole 14 for use with the pin rod 13, and the number of the pin holes 14 is several;

[0037] The present embodiment takes into account that the surface of the wind tower is often installed with a reinforcement ring 4 to improve the stability of the wind tower. However, the existing reinforcement ring 4 is too limited in use, and the position of the reinforcement ring 4 cannot be reasonably adjusted after installation. Therefore, by setting an adjustment mechanism, the twisting block 22 can be rotated to drive the threaded rod 11 to rotate. While the threaded rod 11 rotates, it will squeeze the internal thread in the moving block 12, so that the moving block 12 moves upward, and the moving block 12 drives the pin 13 to leave the inside of the pin hole 14. At this time, the shell 10 and the second U-shaped block 7 are no longer restricted, and can drive the T-shaped block 8 to slide along the trajectory of the T-shaped slot 9. The second U-shaped block 7 will drive the support rod 6 to rotate appropriately around the rotation, and then pry the reinforcement ring 4 to move upward. When the reinforcement ring 4 moves to the appropriate position, the twisting block 22 is rotated in the opposite direction. Contrary to the above description, the pin 13 will move downward and enter the corresponding pin hole 14 to complete the adjustment of the position of the reinforcement ring 4.

[0038] The invention solves the problem that a reinforcement ring 4 is often installed on the surface of a wind tower to improve the stability of the wind tower, but the existing reinforcement ring 4 is too limited in use and the position reinforced by the reinforcement ring 4 cannot be reasonably adjusted after installation.

[0039] Preferably, a bearing 21 is provided at the bottom of the threaded rod 11, and the threaded rod 11 is rotatably connected to the inner wall of the housing 10 through the bearing 21;

[0040] In this embodiment, the bearing 21 is provided to support the threaded rod 11 and restrict the threaded rod 11 to rotate, thereby improving the smoothness of its rotation.

[0041] Preferably, a twisting block 22 is fixedly connected to the top of the threaded rod 11, and twisting grooves 23 are provided on both sides of the twisting block 22;

[0042] This embodiment provides a lever point for fingers by providing the twisting block 22 and the twisting groove 23 , so that the user can easily rotate the twisting block 22 .

[0043] Embodiment 2:

[0044] On the basis of the first embodiment, the adjustment mechanism in this embodiment can adjust the position of the reinforcement ring 4, so as to improve the reinforcement effect of the wind tower 3. However, under the action of strong wind, even if the wind tower is reinforced with the reinforcement ring 4, slight vibration will occur, which will affect the stability of the wind tower. The buffer mechanism in this application includes a buffer frame 15 fixedly connected to the surface of the reinforcement ring 4. The number of buffer frames 15 is four. A buffer block 16 is arranged inside the buffer frame 15. One side of the buffer block 16 is fixedly connected to two springs 17, and the other side of the buffer block 16 is fixedly connected to a buffer rod 18. The other end of the spring 17 is fixedly connected to the inner wall of the buffer frame 15, and one end of the buffer rod 18 passes through the interior of the reinforcement ring 4 and is fixedly connected to a fitting block 19.

[0045] This embodiment takes into account that under strong wind, even if the wind tower is reinforced with a reinforcement ring 4, slight vibration will occur, which will affect the stability of the wind tower. Therefore, by providing a buffer mechanism, when the wind tower 3 shakes slightly, it can squeeze the fitting block 19, and the fitting block 19 will drive the buffer rod 18 and the buffer block 16 to move to the side close to the spring 17. The buffer block 16 squeezes the spring 17 to relieve the force generated by the shaking of the wind tower, thereby playing a buffering role.

[0046] The problem that under strong wind, even if the wind tower is reinforced with the reinforcement ring 4, slight vibration will occur, which will affect the stability of the wind tower, is solved.

[0047] Preferably, a non-slip pad 20 is fixedly connected to one side of the fitting block 19, and the material of the non-slip pad 20 is rubber;

[0048] In this embodiment, the anti-skid pad 20 is provided to make the fitting block 19 and the wind tower fit more closely. At the same time, the rubber material of the anti-skid pad 20 itself can also play a partial buffering effect.

[0049] Working principle: by rotating the twisting block 22, the twisting block 22 drives the threaded rod 11 to rotate, and the threaded rod 11 will squeeze the internal thread in the moving block 12 while rotating, so that the moving block 12 moves upward, and the moving block 12 drives the pin rod 13 to leave the inside of the pin hole 14. At this time, the shell 10 and the second U-shaped block 7 are no longer restricted, and can drive the T-block 8 to slide along the track of the T-slot 9. The second U-shaped block 7 will drive the support rod 6 to rotate around appropriately, and then pry the position of the reinforcement ring 4 upward. When the reinforcement ring 4 moves to the appropriate position, the twisting block 22 is rotated in the opposite direction. Contrary to the above description, the pin rod 13 will move downward and enter the corresponding pin hole 14 to complete the adjustment of the position of the reinforcement ring 4.

[0050] At the same time, when the wind tower 3 shakes slightly, it squeezes the fitting block 19, and the fitting block 19 drives the buffer rod 18 and the buffer block 16 to move to the side close to the spring 17. The buffer block 16 squeezes the spring 17 to alleviate the force generated by the shaking of the wind tower and play a buffering role.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
