Embodiment Construction
[0021] In order to solve the problems existing in the current wind power generation device, the wind power generation system of the present invention has announced a double-rotor wind turbine structure with brackets, which can simultaneously solve the processing, manufacturing and transportation problems of super long blades; The beam structure can improve the strength of the blade and reduce deformation and flutter; the bracket beam structure, the blade can be properly kept away from the tower, and the possibility of the blade hitting the tower is solved; the large and small rotors have different circumferential speeds, and the small rotor has a high speed, which can Make the small rotor have the same tip speed as the large rotor, improve the working efficiency of the blade in the small radius area, and thus greatly reduce the chord length and weight of the blade.
[0022] The present invention will be further described in detail below in conjunction with the accompanying draw...
