The invention discloses a double-wind-wheel offshore floating type wind turbine generator. The double-wind-wheel offshore floating type wind turbine generator comprises a front wind wheel, a rear wind wheel, a rear hub, a cabin, a front hub, a tower drum, a floating body, a catenary and an anchoring device, wherein the front wind wheel is arranged in the upwind direction, the rear wind wheel is arranged in the downwind direction, the front wind wheel and the rear wind wheel are connected to the two ends of the cabin through the hubs, and the cabin, the tower drum and the floating body are sequentially connected from top to bottom; a yawing system is arranged at a flange plate between the cabin and the tower drum; blades of the front wind wheel and blades of the rear wind wheel are respectively connected to the front hub and the rear hub through flange plates; a variable pitch system is arranged at the flange plate, connected to the front hub, of each blade of the front wind wheel; a variable pitch system is arranged at the flange plate, connected to the rear hub, of each blade of the rear wind wheel; and the rear wind wheel can fully capture remaining wind energy of the front wind wheel, gradient utilization of the wind energy is achieved, the comprehensive wind energy utilization coefficient of the wind turbine generator is increased, wake flow effects are reduced, and the sea area utilization rate and the whole power generation efficiency of an offshore wind plant are improved.

    本发明公开一种双风轮海上浮式风电机组,包括前风轮、后风轮、后轮毂、机舱、前轮毂、塔筒、浮体、悬链线以及锚定装置;前风轮布置于上风向,后风轮布置于下风向,前风轮与和后风轮通过轮毂与机舱两端相连,机舱、塔筒和浮体由上至下依次相连;机舱与塔筒之间的法兰盘处有偏航系统;前风轮的叶片和后风轮的叶片分别与前轮毂和后轮毂之间通过法兰盘相连;前风轮的每个叶片与前轮毂连接的法兰盘处设置有变桨系统;后风轮的每个叶片与后轮毂连接的法兰盘处设置有变桨系统;后风轮可以充分捕获前风轮剩余风能,实现风能的梯级利用,提高风电机组综合风能利用系数,减少尾流影响,提升海上风电场海域利用率和整场发电效率。
