Technical Field

[0001] The utility model relates to a fan tower accessory, in particular to a hemispherical anti-collision damping device. Background Art

[0002] Wind turbine towers are high-rise buildings that need to be equipped with damping parts. The existing technology mostly uses mechanical damping devices, and the springs have fatigue limits. In addition, the existing technology has the risk of excessive vibration amplitude during operation, causing internal collision and failure of the damping device. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a hemispherical anti-collision damping device, which has a simple structure, low cost and long durability. The technical solution adopted by the utility model is as follows:

[0004] A hemispherical anti-collision damping device comprises a side plate, an upper hemispherical plate and a lower hemispherical plate, wherein the upper hemispherical plate and the lower hemispherical plate are arranged in parallel and spaced apart with a damping element in the space, and the side plate is annular and used for connecting the side surfaces of the upper hemispherical plate and the lower hemispherical plate.

[0005] The damping element of the above-mentioned hemispherical anti-collision damping device is a pulley.

[0006] The above-mentioned hemispherical anti-collision damping device has universal wheels installed on the upper and lower ends of the pulley. The universal wheel on the upper end of the pulley contacts the upper hemispherical plate, and the universal wheel on the lower end of the pulley contacts the lower hemispherical plate.

[0007] The beneficial effects of the utility model are as follows: by fixing the device horizontally inside the wind turbine tower (building), the combined effect of the inertia of the damping element and gravity can achieve the effect of damping and shock reduction. The device has a simple structure, low cost, long durability, and good shock reduction and damping effect. The device can also avoid the risk of internal impact and failure of the damping device caused by excessive vibration amplitude of the building. BRIEF DESCRIPTION OF THE DRAWINGS
