New energy solves the energy crisis of the mankind.Wind energy has environment friendly and pollution-free as a kind of clean energy resource, and inexhaustible uses it
The advantages of inexhaustible.And wind-driven generator is then to transform wind energy into mechanical energy, mechanical energy changes into the power equipment of electric energy, existing
Wind-driven generator have the disadvantages that：Blade is oversize, transports and install relatively difficult, and because blade area is big, causes
High wind weather even typhoon weather, wind area is excessive, and the even whole wind-driven generator of blade is caused to damage.
The content of the invention
In view of the shortcomings of the prior art, it is the present invention is intended to provide a kind of with flexible blade, transport and easy for installation, safety
The higher wind-driven generator of property.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of wind-driven generator with flexible blade, including support, be provided with the support fan shaft, rotate it is single
Member, generator unit and flexible blade, the fan shaft connect with generator unit, and the flexible blade passes through the rotating unit
It is rotatablely connected with the fan shaft, control unit, the generator unit, rotating unit, flexible leaf is installed in the support
Piece is connected with described control unit.
As a further improvement on the present invention, the flexible blade includes fixed part and pars contractilis, and the pars contractilis passes through
Telescopic cylinder is connected with the fixed part.
As a further improvement on the present invention, it is installed with adjusted device on the support.
As a further improvement on the present invention, the adjusted device is driftage empennage.
As a further improvement on the present invention, the rotating unit includes electric rotating machine.
As a further improvement on the present invention, the generator unit includes gear-box, generator and transformer.
Compared to prior art, the wind-driven generator with flexible blade of the invention passes through flexible blade and rotating unit
Design, solve transport and installation problem, while when in use, the length for the blade that can be stretched according to the big minor adjustment of air quantity,
Avoid the velocity of rotation of blade too fast, at the same strong wind even typhoon weather, flexible blade can be rotated by rotating unit
It is to flexible blade plane parallel with wind direction, wind area is reduced with this, prevents strong wind to caused by blade and wind-driven generator
Damage, increases the service life of wind-driven generator, has wide market prospects and application prospect.
