The invention provides a floating wind turbine foundation. A tower and a wind turbine are borne by a first cylinder on the upper layer, a float is arranged through a second cylinder on the lower layer, and the first cylinder and the second cylinder are arranged in a nested manner and can rotate relative to each other. According to the floating wind turbine foundation, the wind turbine, the tower and the first cylinder are connected into a whole which can rotate freely relative to the second cylinder, a wind indicator effect is produced, automatic adjustment of the load direction is achieved, and in cooperation with a yaw system on the wind turbine, wind energy can be captured and utilized to the greatest extent; and multi-point distributed tension-leg mooring chains are adopted for anchoring to achieve a single-point mooring effect, the anchoring chains replace a tension tendon system, and the adaptability of the floating wind turbine foundation to different water depth environments isimproved on the premise of ensuring the motion performance of a typical tension-leg platform.
本发明提供一种漂浮式风机基础,通过上层的第一筒体承载塔架及风机,通过下层的第二筒体设置浮筒;第一筒体与第二筒体嵌套设置且可相对转动。本发明使风机、塔架与第一筒体连接为可相对第二筒体自由转动的整体,产生风向标效应,实现受载方向的自动调整,配合风机上的偏航系统,能够最大程度地捕捉和利用风能;本发明还采用多点分布张力腿式系泊链锚固实现单点系泊作用,其中以锚链取代张力筋腱系统,在保证典型张力腿式平台运动性能的前提下,提高漂浮式风机基础对不同水深环境的适应性。
