Problems solved by technology
[0004] The current vibration damping devices mostly use one method to reduce structural vibration, so that the wind energy cannot be fully converted into other forms of energy under the action of strong wind; in addition, the existing vibration damping devices can only control a certain direction or several directions Considering the complexity of the environment in which the wind power tower structure is located, the traditional vibration damping device cannot well deal with the wind vibration response caused by the wind blowing in the most unfavorable direction

The invention discloses a blade-type energy consumption tuning vibration damping device, which comprises a vibration damping box installed on a turntable, and mass blocks capable of sliding back and forth along the surface are respectively installed on the lower bottom surface and the upper top surface of the vibration damping box , the mass block is connected to the side wall of the shock absorbing box through a parallel viscous damper and an elastic element, and a liquid damper connected to the inner wall of the shock absorbing box is arranged laterally between the upper and lower mass blocks. A horizontally arranged rotating vane shaft is installed in the liquid damper, and the rotating vane shaft extends out of the vibration damping box and is connected with the vanes.
Description
technical field [0001] The invention belongs to wind vibration control of wind power generation towers and related towering structures, and in particular relates to a blade type energy consumption tuning vibration damping device. Background technique [0002] With the development and utilization of wind power energy, wind power towers have been vigorously promoted in recent years. In view of its important role in economic development and environmental protection, it is of great significance to ensure the safe and stable work of wind power tower structures under wind loads. The wind power tower has a high structural height, and its main weight is concentrated on the wind turbine system at the top of the tower, and due to its special working nature, it is easily affected by wind loads. When the wind power tower structure system is excited by external loads such as wind loads, the system obtains energy input, thereby generating a corresponding dynamic response. [0003] Curre...
