Technical Field
[0001] The utility model relates to a shock absorbing device, in particular to a high-damping wind power tower built-in shock absorbing device, belonging to the technical field of wind power towers. Background Art
[0002] In the prior art, for example, the utility model with application number 202223138361.1 discloses a high-damping wind tower that is easy to shock absorb. In order to solve the problem that the wind direction is constantly changing, causing the wind turbine cabin to always track the wind direction, thereby generating a huge rotational torque, making it difficult for the tower to reduce the vibration caused by its force, the vibration generated by the tower body can be buffered and weakened by the arrangement of the shock-absorbing assembly, by utilizing the coordination between the damping rod, spring, connecting plate, through hole, connecting ring and steel strand. This can further improve the stability of the tower body. At the same time, under the action of the shock-absorbing pad, the steel strand can be buffered and protected to prevent it from breaking.
[0003] Similar to the above application, there are still some shortcomings:
[0004] Since the wind turbine tower is subjected to a horizontal rotational torque, the horizontal torque cannot be well converted into a vertical force by pulling the steel strands, resulting in a poor shock absorption effect of the device. In addition, the damping rod is not only subjected to a vertical force, but also to a large rotational torque, which can easily cause damage to the damping rod.
[0005] Therefore, a high-damping wind turbine tower built-in shock-absorbing device is designed to optimize the above problems. Utility Model Content
