一种半潜漂浮式风机基础结构

本发明提供了一种半潜漂浮式风机基础结构，包括海上风力发电组件和漂浮组件，漂浮组件包括中心浮筒和基础浮筒，漂浮组件还包括设置于中心浮筒和基础浮筒上的抗波浪平板，抗波浪平板上设置有通孔。本发明所提供的一种半潜漂浮式风机基础结构在中心浮筒和基础浮筒上均设置有抗波浪平板，抗波浪平板可以破碎波浪并吸收能量，削弱海浪对于漂浮组件的冲刷，消耗波浪中的冲击能量，削弱海浪对于塔柱的冲击力，减少塔柱受到的疲劳损伤；可以大幅减轻海上风力发电组件在风、浪、流耦合作用下的运动响应，增强海上风力发电组件的稳定性，减少海上风力发电组件的中心浮筒和基础浮筒受到海浪冲刷造成的疲劳损伤，延长海上风机整体的使用寿命。

The invention provides a semi-submersible floating type wind turbine foundation structure which comprises an offshore wind power generation assembly and a floating assembly. The floating assembly comprises a center buoy and foundation buoys, the floating assembly further comprises anti-wave flat plates arranged on the center buoy and the foundation buoys, and through holes are formed in the anti-wave flat plates. According to the semi-submersible floating type wind turbine foundation structure, the anti-wave flat plates are arranged on the center buoy and the foundation buoys, the anti-wave flat plates can break waves and absorb energy, scouring of sea waves to the floating assembly is weakened, impact energy in the waves is consumed, impact force of the sea waves to a tower column is weakened, and fatigue damage to the tower column is reduced. Motion response of the offshore wind power generation assembly under the coupling action of wind, waves and flow can be greatly reduced, the stability of the offshore wind power generation assembly is enhanced, fatigue damage caused by sea wave scouring to the center buoy and the foundation buoys of the offshore wind power generation assembly is reduced, and the service life of a whole offshore wind turbine is prolonged.
