【Specific embodiment】
To make the purpose of the present invention, technical solution and effect clearer, clear and definite, it gives an actual example below further to the present invention
It is described in detail；It should be appreciated that described herein, the specific embodiments are only for explaining the present invention, is not intended to limit the present invention.
Embodiment one
As shown, a kind of wind electricity generating system, including mounting bracket, mounting bracket is equipped with shaft, multiple by turning
The dynamic blade rack for providing wind energy is fixedly connected and can be rotated with shaft；Blade rack includes the main support positioned at upper and lower ends,
Upper and lower two main support is connected to shaft by main framing；Main support is wide, wind deflector that both ends are narrow among one, between two main supports
Equipped with a plurality of vertical secondary support side by side, secondary support both ends are connected to corresponding wind deflector rear end, between adjacent two secondary support
It is provided with a plurality of mobilizable blade side by side up and down, concave shape is collectively formed in blade, upper-lower wind shield and secondary support；Blade upper end
Enter in secondary support corresponding aperture equipped with latch, latch is cased with torsional spring, and torsional spring uses routine techniques and function, i.e. effect one end of torsional spring
Shi Shouli (torsional spring deformation) does not stress (torsional spring is indeformable) when acting on the other end；One end of torsional spring connects blade, other end auxiliary connection
Bracket, blade can be swung around torsional spring, and torsional spring makes to be obstructed when blade is positive movable, and smooth when reverse activity, i.e., blade is in wind-force
When effect forward direction is swung, torsional spring deformation generates reaction force to blade and blade rack is pushed to rotate, at this point, wind-force is to other
The effect of blade is just backswing, and torsional spring does not have reaction force to blade, and blade, which is easy to swing open, to be played and unload wind work
With, make on the whole blade rack rotation it is more smoothly, improve wind-force efficiency；When blade forward direction is swung, due to the effect of torsional spring, wind
Power increases the active force of blade rack with blade oscillating amplitude and increases, and blade rack revolving speed increases, but blade is opened at this time
Amplitude it is big, unload that wind energy power is also bigger, and can effectively avoid keeps blade rack revolving speed too fast because wind-force is excessive, improve using safe
Property.
Embodiment two
In the present invention, main support is arc strip, and length direction section is wedge shape, and wedge angle direction and blade forward direction are put
Dynamic direction is consistent, to further increase the efficiency of wind；Wind deflector is formed between main support outer arc chord；Other are the same as embodiment one.
Embodiment three
In the present invention, a blade is provided between adjacent two secondary support, other are the same as embodiment one.
Example IV
In the present invention, a blade is provided between adjacent two secondary support, other are the same as embodiment two.
In above-described embodiment, blade forms the positive wind resistance of large area, place under self gravity in closed form
Become the empty shelf of seldom windage because wind-force effect opens blade in the blade of other one side, so that wind-engaging and unloading
The contrast of wind increases, so moving vane many electricity more multiple than existing wind-driven generator in the case where wind-force is same, with
The preceding confidential wind speed 5-7m/s of big group of wind-power electricity generation, that is to say, that fresh breeze that could generate electricity.And moving vane of the present invention is in wind speed
1m/s or more can start running power generation, will know that difference by the probability of occurrence of gentle breeze and fresh breeze；This
The moving vane of invention can be made body greatly, because moving vane wind power generating set can be made spider reticulation, body
Each structural steel cord connection；Institute's organism and blade of the present invention can modularization Production line combination installation, with drop
Low production cost and technical difficulty.The present invention could be applicable to hydroelectric generation.
