According to the self-stabilization floating type draught fan foundation, the truss structure extending downwards is connected to the bottom of the center stand column of the floating type draught fan foundation, the solid ballast is connected to the bottom of the truss structure, the gravity center of the whole machine is greatly lowered, the gravity center is located below the buoyancy center, and a self-stabilization structure is formed; in order to facilitate towing, a truss type connecting structure between the central upright post and the bottom solid ballast is designed into a telescopic structure; the floating fan foundation adopts an upper group of mooring cables and a lower group of mooring cables so as to limit the six-degree-of-freedom motion response of the floating fan foundation under the action of external loads such as wind waves and flows. In addition, the side stand columns of the floating type draught fan foundation incline in the opposite direction of the connecting line of the side stand columns and the center stand column, so that the restoring torque provided by the side stand columns is increased, and the pitching and rolling performance of the floating type draught fan foundation is improved.
本发明提供了一种自稳性浮式风机基础,通过在浮式风机基础中心立柱的底部连接向下延伸的桁架结构并在桁架结构底部连接固体压载物,极大的降低整机重心,使重心位于浮心之下,形成自稳性结构;为方便拖航,将中心立柱与底部固体压载物之间的桁架式连接结构设计为可伸缩结构;该浮式风机基础采用上下两组系泊缆,以限制其在风浪流等外部载荷作用下的六自由度运动响应。此外,本发明将该浮式风机基础的边立柱向其与中心立柱连线的反方向倾斜,以增大边立柱提供的回复力矩,提高浮式风机基础的纵摇和横摇性能。
