Device for controlling wind-induced vibration of power transmission tower-line system
The invention provides a device for controlling wind-induced vibration of a power transmission tower-line system, and particularly relates to the field of power transmission tower vibration control. The device comprises a shell and an elastic rod. The shell comprises an upper plate face and a plurality of fixing plates distributed at equal intervals in the circumferential direction of the bottom of the upper plate face. A plurality of swinging plates are connected between the adjacent fixing plates through rotating shafts; a through hole is formed in the center of the upper plate surface; the elastic rods penetrate through the through holes and are fixed to the upper plate face through adjusting bolts. When the power transmission tower-line system generates wind-induced vibration, the swing ball swings to impact the swing plate, vibration energy is dissipated through impact, and the safety of the whole structure is protected. According to the device, vibration control of different frequencies of the power transmission tower-line system can be controlled according to selection of balancing weights of different weights, and the device is convenient to install and maintain and easy to use.
本发明提供了一种用于控制输电塔‑线体系风致振动的装置,具体涉及输电塔振动控制领域。该装置包括外壳和弹性棒，所述外壳包括上板面和上板面底部沿周向等间距分布有若干固定板；所述相邻固定板之间通过转轴连接有若干摆动板；所述上板面的中心位置设置有通孔；所述弹性棒贯穿通孔并通过调整螺栓与上板面固定。当输电塔‑线体系发生风致振动时，摆球发生摆动，撞击摆动板，通过撞击耗散振动能量，保护整体结构安全。本发明装置中可根据选用不同重量的配重块，控制输电塔‑线体系不同频率的振动控制，且安装便捷、维修方便、使用简单。
