The utility model is by setting the drive device that blade enhanced portion and driving blade enhanced portion are deployed, when wind-force is smaller
When back-moving spring reset and drive inner ring body to rotate forward, and then driving blade enhanced portion withdraw；When wind-force is larger, wind is blown
Driving blade, driving blade drive inner ring body to reversely rotate, and then driving blade enhanced portion is deployed, and increases width of blade, enters
And increase lifting surface area, improve the ability of blade capture moment of torsion and wind energy.
Brief description of the drawings
Fig. 1 is a kind of structural representation for the blade of wind-driven generator for automatically adjusting width of the utility model.
Embodiment
Illustrate below in conjunction with the accompanying drawings, the utility model is described in further detail.
As shown in figure 1, a kind of blade of wind-driven generator for automatically adjusting width, including blade body 1 and drive device,
The both sides of the edge of blade body 1 are equipped with blade enhanced portion, and each blade enhanced portion includes enhancing blade 2 and rotating shaft 21, enhancing
Blade 2 is fixedly connected on rotating shaft 21, and rotating shaft 21 is axially moveable to be connected to the side edge of blade body 1, specifically, blade sheet
The inside of body 1 has cavity, and rotating shaft 21 is arranged in cavity, the axle sleeve for being used for installing rotating shaft 21 is provided with cavity, enhancing blade 2 can
To be fixedly connected on rotating shaft 21 by multiple connecting rods, the back side of blade body 1 is provided with the opening for connecting rod activity, blade sheet
The back side of body 1 is the one side backwards to wind.Drive device is arranged at blade body 1, and can drive shaft 21 rotate.
Wherein, drive device includes outer ring body 31, inner ring body 32, back-moving spring 33 and multiple driving blades 34, outer ring body
31 one end are fixedly connected on the tail end of blade body 1, and outer ring body 31 is sheathed on inner ring body 32, and inner ring body 32 can be relative to outer ring body
31 rotate.The one end of inner ring body 32 away from blade body 1 is sheathed on inner ring body 32 integrally formed with extension, back-moving spring 33
Extension, the one end of back-moving spring 33 are fixedly connected on outer ring body 31, and the other end is fixedly connected on the extension of inner ring body 32, when multiple
Position spring 33 in the raw when, enhancing blade 2 be in retracted state.Multiple rings of driving blade 34 are distributed in inner ring body 32
On the lateral wall of end, driving blade 34 can be connected on the extension of inner ring body 32 extension with spiral.Inner ring body 32
The first bevel gear 35 is coaxially installed with close to one end of blade body 1, the end of rotating shaft 21 is installed with and the first umbrella
The second bevel gear 36 that shape gear 35 engages, rotating shaft 21, the first bevel gear 35 and the second bevel gear 36 are respectively positioned on blade
In the cavity of body 1, thus, inner ring body 32 can pass through the cooperation of the first bevel gear 35 and the second bevel gear 36 when rotating
Carry out drive shaft 21 to rotate, so as to drive enhancing blade 2 to deploy or withdraw.
