Wind generating set tower capable of automatically adjusting damping properties
The invention discloses a wind generating set tower capable of automatically adjusting damping properties. The wind generating set tower comprises a tower structure, an inner layer supporting shell structure, an air pump and a control system; the top end and the bottom end of the inner layer supporting shell structure are respectively connected with the inner wall of the tower structure to form aclosed damping cavity; damping liquid is injected into the damping cavity; a plurality of inflating bags connected with the air pump are arranged at the bottom in the damping cavity, and exhaust holesare arranged in the top of the damping cavity; an acceleration acquisition system is arranged on the tower structure; and the control system is connected with the acceleration acquisition system andthe air pump and is used for controlling the air pump to adjust the volume of the inflating bags according to the acceleration measured by the acceleration acquisition system so as to change the height of the damping liquid in the damping cavity. According to the wind generating set tower, the frequency of liquid damping can be accurately adjusted according to the actual vibration condition of thetower so as to achieve the optimal vibration suppression effect. The height of the damping liquid does not need to be adjusted manually, and the risk caused by damping adjustment deviation is reduced.
本发明公开了一种可自动调节阻尼属性的风力发电机组塔架，该风力发电机组塔架包括：塔架结构、内层支撑壳结构、气泵及控制系统；所述内层支撑壳结构的顶端和底端分别与所述塔架结构内壁连接，以形成封闭的阻尼腔；所述阻尼腔内注有阻尼液；所述阻尼腔内的底部设有多个与所述气泵相连的充气囊，所述阻尼腔的顶部设有排气孔；所述塔架结构上设有加速度采集系统；所述控制系统分别与加速度采集系统和气泵相连，用于根据加速度采集系统测量的加速度控制气泵调节充气囊的体积以改变阻尼腔内的阻尼液高度。本发明可根据塔架的实际振动情况，精确的调整液体阻尼的频率，达到最佳的抑振效果。无需手动调节阻尼液高度，减小阻尼调节偏差带来的风险。
