The invention provides an offshore floating type fan foundation which comprises three stand columns and heaving plates, the heaving plates are arranged below the stand columns, the three stand columnsare arranged in a regular triangle shape, truss structures are arranged between the adjacent stand columns, and the truss structures are symmetrically distributed on the three sides of the regular triangle. The stand column comprises a first inner-layer steel plate and a first outer-layer steel plate, the first inner-layer steel plate and the first outer-layer steel plate are each of a hollow column structure, the first inner-layer steel plate is arranged in a hollow column of the first outer-layer steel plate, and the first outer-layer steel plate and the first inner-layer steel plate are coaxially arranged. Wherein one stand column is provided with an installation part used for installing a wind power tower drum. Concrete is poured into a cavity between the first outer-layer steel plateand the first inner-layer steel plate, the steel consumption is reduced while the rigidity and fatigue strength of the foundation structure are enhanced, and the cost is saved.
本发明提供一种海上浮式风机基础,包括立柱和垂荡板,所述垂荡板设置在立柱下方,所述立柱设置有三个,三个立柱呈正三角形布置,相邻立柱之间设置有桁架结构,所述桁架结构对称分布于正三角形的三边上,所述立柱包括第一内层钢板和第一外层钢板,所述第一内层钢板和第一外层钢板均为空心柱结构,所述第一内层钢板设置在第一外层钢板的空心柱内,所述第一外层钢板和第一内层钢板同轴线设置,其中一个立柱上设置有用于安装风电塔筒的安装部。所述第一外层钢板和第一内层钢板之间的空腔内浇筑有混凝土,增强基础结构的刚度和疲劳强度的同时减少用钢量,节约成本。
