The invention provides a wind power floating foundation of a double-stand-column structure. The wind power floating foundation comprises a first stand column, a second stand column, a stand column connecting piece and a plurality of mooring chains. The mooring chains are connected to the bottom of the second stand column so that the second stand column can float in a designated sea area. The first stand column and the second stand column are arranged in parallel at intervals, the first end of the stand column connecting piece is connected to the circumferential side wall of the first stand column, the second end of the stand column connecting piece is rotationally connected to the second stand column, and the first stand column can rotate around the circumferential direction of the second stand column through the stand column connecting piece. The stand column connecting piece is located above the sea level. The fan tower drum is arranged on the top of the first stand column in the buoyancy direction. The problems that in the prior art, the anti-torque capacity is poor, the structure is complex, and cost is high are solved.
本发明提供了一种双立柱构型的风电浮式基础,包括第一立柱、第二立柱、立柱连接件以及多个系泊链。多个系泊链连接于第二立柱的底部,以使得第二立柱漂浮于指定海域。第一立柱和第二立柱并列间隔设置,立柱连接件的第一端连接于第一立柱的周向侧壁,立柱连接件的第二端转动连接于第二立柱,第一立柱能够通过立柱连接件绕第二立柱的周向转动。其中,立柱连接件位于海平面以上。风机塔筒设于第一立柱沿浮力方向的顶部。解决了现有技术中存在的抗扭矩能力不佳、结构复杂且成本高昂的问题。
