The invention discloses a cascade type floating foundation for a multi-impeller wind power system. The cascade type floating foundation comprises a floating structure and mooring cable connecting pieces. The floating structure is mainly composed of a transition section and a floating box or a floating barrel. The number of the floating structures is not less than 2. Each floating structure is connected with the supporting structure, and at least one floating structure is located in the upwind direction or the downwind direction of the impeller. The mooring rope connecting piece comprises a rotating ring and a fixed ring, and the rotating ring and the fixed ring can rotate relatively. The mooring rope connecting piece fixing ring is connected with the mooring rope, and the mooring rope connecting piece rotating ring is connected with one floating structure or connected with all the floating structures through inhaul cables. According to the cascade type floating foundation, the supporting capacity of the foundation is equivalently improved through the multiple small floating structures which are arranged in a scattered mode, and the risk of system overturning is greatly reduced while the economical efficiency of the floating foundation is guaranteed.

    本发明公开了一种多叶轮风电系统用级联式浮动基础。级联式浮动基础包含漂浮结构和系泊索联接件。漂浮结构主要由过渡段及浮箱或者浮筒组成。漂浮结构的数量不少于2个。每个漂浮结构都与支撑结构联接,至少有1个漂浮结构位于叶轮的上风向或者下风向。系泊索联接件包含转动圈和固定圈,转动圈和固定圈可以发生相对转动。系泊索连接件固定圈与系泊索联接,系泊索联接件的转动圈与一个漂浮结构联接或者通过拉索与全部漂浮结构联接。级联式浮动基础利用分散布置的多个较小型的漂浮结构等效增加了基础的支撑能力,在保证浮动基础经济性的同时,大大降低了系统倾覆的风险。
