The invention discloses a tension leg type floating platform and a floating wind power system. The tension leg type floating platform comprises a plurality of floating bridges, the plurality of floating bridges form a polygonal structure, each corner of the polygonal structure is provided with a buoy, and every two adjacent buoys are connected through the corresponding floating bridge; the extension arms have buoyancy, the number of the extension arms is consistent with that of the buoys, the extension arms are connected to the buoys and correspond to the buoys in a one-to-one mode, and tension cables are arranged at the ends, away from the polygonal structure, of the extension arms respectively; the bottom end of the supporting frame is connected to the top ends of the buoys and is supported by the buoys. According to the tension leg type floating platform, the distance between the tension cable and the buoy is increased through the extension arm, the water flow load, stress and fatigue of the buoy can be reduced, the heaving, rolling and pitching motion periods of the tension leg type floating platform are shortened, and therefore the stability and overall performance of the tension leg type floating platform are improved.
本发明公开了一种张力腿式浮式平台及浮式风电系统,所述张力腿式浮式平台包括:若干个浮桥,若干个所述浮桥组成多边形结构,多边形结构的各个拐角处分别设有一浮筒,各相邻的两个所述浮筒之间通过所述浮桥连接;具有浮力的延伸臂,所述延伸臂数量与浮筒一致,各个所述延伸臂分别连接于各个所述浮筒并一一对应,且各个所述延伸臂远离所述多边形结构的一端分别设有张力索;支撑架,所述支撑架的底端连接于各个所述浮筒的顶端并通过各个所述浮筒支撑。本发明通过延伸臂增加张力索与浮筒之间的距离可以降低浮筒受到水流载荷、应力及疲劳度,并减少张力腿式浮式平台的垂荡、横摇和纵摇运动周期,从而提高张力腿式浮式平台的稳定性及整体性能。
