Description
Technical field
The present invention relates to a kind of wind power generation plants, belong to technical field of wind power generating equipment.
Background technology
The wind-driven generator of existing wind-power electricity generation generally use rotor and stator realizes power generation, in low speed rotation, because
Internal resistance is excessive, can not produce electricl energy, capacity usage ratio is low.
Invention content
The technical problem to be solved by the present invention is to：A kind of wind power generation plant is provided, it is existing in the prior art to solve
Problem.
The technical solution that the present invention takes is：A kind of wind power generation plant, including shaft tower, birotor generator and blade,
Shaft tower top is fixedly connected with birotor generator, and two rotation axis of birotor generator have been fixedly connected with the symmetrical leaf of two panels
Piece.
Preferably, above-mentioned birotor generator includes casing, rotor one and rotor two, the rotation axis of one left end of rotor connection
It is connected on casing by bearing, the rotation axis of two right end of rotor connection is connected to by bearing on casing, and the insertion of rotor two turns
In son one.
Preferably, above-mentioned blade is cat owl wing structure.
Preferably, above-mentioned rotor one is fixedly connected on the rotating shaft by connecting flange.
Beneficial effects of the present invention：Compared with prior art, effect of the invention is as follows：
1）The present invention is rotated in mutually opposite directions between birotor by using birotor generator, and relative velocity is compared to stator and turns
Son improves 1 times, and energy will greatly improve, and the electric energy of conversion is bigger, and birotor relative rotation speed is big, can be to being carried out under low wind speed
Wind energy efficiently uses, capacity usage ratio higher, effectively solves the problems, such as to cannot achieve power generation under low speed, and two vane types
Rotation, faster, electric energy further realizes conversion to rotating speed, and the present invention also has the characteristics that simple in structure, at low cost；
2）Because of the rotation of two vane types, noise is big, therefore blade is made cat owl wing structure, because its surface is wavy
Structure can effectively solve the problem that noise problem, substantially reduce the noise of blade rotation.
