Suspended ballast type offshore wind turbine floating type foundation structure
The invention discloses a suspended ballast type offshore wind turbine floating type foundation structure. The structure comprises a wind turbine, a floating type supporting foundation and mooring ropes. The floating type supporting foundation comprises a connecting steel support, buoys, suspension chain ropes and a suspended ballast structure. A floating body on the upper part and the suspended ballast structure on the lower part are connected together through the suspension chain rope. Intermediate steel is saved, so that the steel consumption is reduced, and the cost is reduced. Diagonal bracing steel supports and a central steel support are arranged at certain angles, bending moment on the central steel support is converted into tension and pressure on the diagonal bracing steel supports, stress is more reasonable, and the included angle between every two planes formed by the axes of the diagonal bracing steel supports and the axes of radial steel supports is 120 degrees. The mooring cables and the suspension chain ropes are both fixed on the radial steel supports, only hydrostatic restoring force/moment load is transmitted between the buoys and the radial steel supports, stress is more reasonable, and stress damage between the buoys and the radial steel supports is effectively relieved.
本发明公开了一种悬挂压载式海上风机浮式基础结构，该基础结构，包括风力机、浮式支撑基础和系泊缆，浮式支撑基础包括连接钢支架、浮筒、悬挂链绳和悬挂压载结构，上部浮体和下部悬挂压载结构两者之间利用悬挂链绳连接在一起，节省了中间钢材，从而节省用钢量降低成本。斜撑钢支架与中央钢支架成一定角度布置，让中央钢支架上的弯矩转化为斜撑钢支架上的拉压力，受力更合理，斜撑钢支架和径向钢支架的轴线所形成的平面之间，两两夹角为120度。系泊缆和悬挂链绳均固定在径向钢支架上，浮筒和径向钢支架之间只传递静水回复力/力矩载荷，受力更合理，有效缓解浮筒和径向钢支架之间的应力破坏。
