The invention relates to a multi-floating-body platform of an offshore floating type wind turbine. The multi-floating-body platform comprises an upper floating body and a lower floating body, whereinthe upper floating body and the lower floating body are connected through tension tendons in a stretching state, the upper floating body comprises a fixed floating cabin, a variable floating cabin anda foundation ballast which are sequentially arranged from top to bottom, the fixed floating cabin is used for providing buoyancy, the variable floating cabin comprises a first cavity and a first ballast pump, and the lower floating body comprises a ballast. Compared with the prior art, the upper floating body moves under the action of an external load, tension of the lower floating body is transmitted to the upper floating body through the tension tendons connected with the lower floating body, movement of the upper floating body is reduced, the speed of the upper floating body recovering tothe balance position is increased, the stability of the system is improved, surging, pitching and yawing responses are reduced, and good movement characteristics of the Spar platform are inherited.
本发明涉及一种海上漂浮式风力机多浮体平台,包括上浮体和下浮体,所述上浮体和下浮体之间通过处于拉伸状态的张力筋腱连接,所述上浮体包括从上到下依次设置的固定浮舱、可变浮舱、基础压载,所述固定浮舱用于提供浮力,所述可变浮舱包括第一腔体和第一压载泵,所述下浮体包括压载物。与现有技术相比,本发明在外界载荷作用下,上浮体发生位移,下浮体的拉力通过与之相连的张力筋腱传递至上浮体,一方面减小了上浮体运动,另一方面加快了上浮体恢复至平衡位置的速度,提高了系统的稳定性,不仅减小了纵荡、纵摇及首摇响应,且继承了Spar平台良好的运动特性。
