The invention discloses a displacement detection method for a floating wind turbine generator, which comprises the following steps of: installing sonar emitters at the center of a floating foundation platform and each buoy of the floating wind turbine generator, lowering an iron chain, tying a weight on the iron chain, installing a sonar receiver on the weight, arranging a chain stopper at the lowering front end of the iron chain, and controlling the lowering of the iron chain through the chain stopper. Through the measured vertical distance between the sonar transmitter and the corresponding sonar receiver and the offset distance after typhoon, the horizontal displacement of all the buoys and the floating type foundation platform after typhoon can be calculated, and the real displacement of all the anchors can be truly reflected. Therefore, the safety of the floating type wind turbine generator is accurately evaluated. The method has the advantages of simplicity and reliability in operation, high feasibility, high precision and the like.

    本发明公开了一种漂浮式风电机组的位移检测方法,该方法是在漂浮式风电机组的漂浮式基础平台中心和每个浮筒装声呐发射器,并下放铁链,铁链上栓着重块,重块上装声呐接收器,铁链下放的前端有个止链器,通过止链器控制铁链下放,通过测得的声呐发射器与相应声呐接收器之间的垂直距离以及台风发生后的偏移距离,可计算出所有浮筒和漂浮式基础平台在台风发生后产生的水平位移,即可真实反映出所有锚发生的真实位移,从而准确评估漂浮式风电机组的安全性。本发明方法具有操作简单可靠、可实施性强、精度高等优点。
