The invention relates to an opposite-pulling self-balancing wind power floating platform which comprises a central tower column used for supporting wind power equipment, a rigid frame used for fixing the central tower column, a plurality of buoys connected to the rigid frame, a lower balancing stand column connected with the rigid frame and an inhaul cable system. The multiple buoys provide buoyancy for the rigid frame, the inhaul cable system comprises upper inhaul cables pulled between the central tower column and the rigid frame and lower inhaul cables pulled between the lower balance stand column and the rigid frame, the upper inhaul cables are distributed in groups in the circumferential direction of the central tower column, and the lower inhaul cables are distributed in groups in the circumferential direction of the lower balance stand column. The upper inhaul cable and the lower inhaul cable of the rigid frame correspond to each other and are stressed in a balanced mode. The floating foundation has the advantages that the internal force of the floating foundation is greatly reduced through the inhaul cables which are oppositely arranged up and down, the bending moment of the central tower column is reduced through the inhaul cables which are oppositely arranged in groups in the circumferential direction, and therefore the steel consumption of the floating foundation and the central tower column is reduced, and the kilowatt-hour cost is reduced.
本申请涉及一种对拉自平衡风电漂浮平台,包括用于支撑风电设备的中央塔柱、固定中央塔柱的刚性框架、连接在刚性框架上的多个浮筒、连接刚性框架的下平衡立柱、以及拉索系统,其中:中央塔柱倾斜设置在刚性框架上,多个浮筒为刚性框架提供浮力,拉索系统包括牵拉在中央塔柱和刚性框架之间的上侧拉索以及牵拉在下平衡立柱和刚性框架之间的下侧拉索,上侧拉索沿着中央塔柱的周向成组分布,下侧拉索沿着下平衡立柱的周向成组分布,刚性框架的上侧拉索和下侧拉索相互对应且受力平衡。其效果是:通过上下对立设置拉索大大减轻了浮式基础的内力,通过周向成组对立布置拉索减小中央塔柱的弯矩,从而减少浮式基础和中央塔柱的用钢量,降低度电成本。
