The invention provides an offshore semi-submersible fan foundation and a wind generating set. The offshore semi-submersible fan foundation comprises a plurality of main buoys, inclined struts, transverse struts and heaving plates, the main buoys are arranged along the vertex positions of a regular polygon, the adjacent main buoys are connected through the inclined struts and the transverse struts, and the heaving plates are coaxially arranged at the bottom ends of the main buoys; the cross sections of the main buoys and the heaving plate are both hyperelliptic; and the extension lines of the long axes of the cross sections of the main buoys and the heaving plate pass through the geometric center of the regular polygon. The main buoys of the offshore semi-submersible fan foundation can effectively reduce the stress concentration coefficient of the joints of the main buoys and the inclined struts and the transverse struts, so that the thickness of each main buoy is reduced, and the weight reduction effect of the floating type foundation is achieved.
本发明提供一种海上半潜式风机基础及风力发电机组,包括主浮筒、斜撑、横撑和垂荡板,主浮筒设置有多个,主浮筒沿正多边形的顶点位置布置,相邻主浮筒之间通过斜撑和横撑连接,垂荡板同轴设置在主浮筒的底端;主浮筒的横截面和垂荡板均为超椭圆形;主浮筒和垂荡板横截面长轴的延长线均通过正多边形的几何中心采用本发明海上半潜式风机基础主浮筒可有效降低主浮筒与斜撑、横撑连接处的应力集中系数,从而降低主浮筒的厚度,起到漂浮式基础减重的效果。
