The invention discloses a floating type fan foundation adopting a groove type stabilization water tank and a wind generating set. The floating type fan foundation adopting the groove type stabilization water tank comprises a mooring system, a foundation structure and an anchoring foundation arranged on the seabed, and the mooring system fixes the foundation structure on the anchoring foundation onthe seabed; and the foundation structure comprises a uniform-section upright column and a variable-section upright column, the lower end of the uniform-section upright column is connected with the upper end of the variable-section upright column, the section of the variable-section upright column is gradually increased from top to bottom, the stabilization water tank is arranged at the lower portion of the variable-section upright column and divided into a plurality of sub-tanks in the circumferential direction, and the sub-tanks are communicated through a communication groove. According to the floating type fan foundation with the groove type stabilization water tank, the whole gravity center of the structure can move downwards, the damping coefficient is increased, the inherent frequency is reduced, and the stability of a foundation platform is improved; and the draft is reduced, so that the application range of the foundation platform structure is expanded.
本发明公开一种采用槽型减摇水舱的漂浮式风机基础及风力发电机组,槽型减摇水舱的漂浮式风机基础包括系泊系统、基础结构以及设置在海底的锚固基础,系泊系统将基础结构固定在海底的锚固基础上,基础结构包括等截面直立柱和变截面直立柱,等截面直立柱下端连接变截面直立柱上端,变截面直立柱的截面从上到下逐渐增大,变截面直立柱的下部设置减摇水舱,减摇水舱沿周向分为若干分舱,分舱之间通过连通槽连通本发明槽型减摇水舱的漂浮式风机基础可以使结构整体重心下移,增大阻尼系数,减小固有频率,增加了基础平台稳性;并且减少了吃水深度,从而扩大了该基础平台结构的适用范围。
