Abstract

The invention discloses a double-wind-wheel wind turbine generator with a cabin of an auxiliary supporting structure. The double-wind-wheel wind turbine generator comprises a front wind wheel, a rear wind wheel, the cabin, a rear cabin supporting structure, a front cabin supporting structure, a yaw system and a tower drum. The tower drum is of an upper and lower section structure, the lower section of the tower drum is arranged on the ground, and the lower section of the tower drum is connected with the upper section of the tower drum through the yaw system; the cabin is arranged at the upper end of the tower drum, the front cabin supporting structure and the rear cabin supporting structure are arranged on the front side and the rear side of the cabin respectively for supporting, one end of the front cabin supporting structure is connected with the front side part of the cabin, and the other end of the front cabin supporting structure is connected with the upper section of the tower drum; one end of the rear cabin supporting structure is connected with the rear side part of the cabin, and the other end of the rear cabin supporting structure is connected with the upper section of the tower drum; and a front hub of the front wind wheel is connected with the front end part of the cabin, and a rear hub of the rear wind wheel is connected with the rear end part of the cabin. The contradiction between aerodynamic efficiency and structural stability is solved.

Description

technical field [0001] The invention belongs to the technical field of wind power, in particular to a double wind turbine wind turbine with an auxiliary support structure in the nacelle. Background technique [0002] The double wind rotor wind turbine is a new type of wind energy utilization device. It has two wind rotors, which can be arranged on the same plane or on different planes, forming two structures of parallel and serial. The side-by-side double wind rotors do not increase the wind energy absorption area, and the two wind rotors are prone to structural interference, and it is difficult to make the diameter of the wind rotors large. The wind energy utilization coefficient and power generation of this structure have not been greatly improved. The two wind rotors of the tandem double wind rotor structure are not limited by the structure. The front and rear arrangement of the wind rotors can effectively absorb the remaining wind energy of the front rotors, realize the ...
