Abstract
The utility model discloses a wind power generator which has a blade automatically aligning to the wind direction. A set of planet gears is arranged on a blade bracket, the amount of teeth of a blade gear is the same as the amount of teeth of a wind vane gear, the blade gear is meshed with the wind vane gear by a middle transmission gear, and the blade is always vertical to the wind direction when wind power drives the blade to rotary. A locking pin causes the blade and the blade gear to be relatively fixed, and a wind vane is provided with a slide block which causes the locking pin to be detached from a locking pin hole. After the locking pin detaches from a locking pin hole, the blade and the blade gear can relatively rotate. A blade reversing gear of the wind vane causes the direction of the blade to be converted from being parallel to the wind direction into being vertical to the wind direction, and the locking pin returns to the locking pin hole under the action of the force of a spring.
Description
Technical field
The utility model relates to the wind-driven generator that a kind of blade is aimed at wind direction automatically, and this wind-driven generator is a vertical axis aerogenerator, when blade of wind-driven generator rotates, utilizes one group of planetary gear to realize that blade surface is vertical with wind direction all the time.
Background technique
At present, the vertical axis aerogenerator of existing multiple structural type.When wind-force effect lower blade rotated, the down wind face of blade that pushing generator rotates was always not vertical with wind direction all the time, and maximum rotatory force is just arranged when having only face of blade vertical with wind direction fully.And second half be in against the wind to blade always wind is produced certain resistance, these resistances are offset the rotatory force that down wind blades are produced, and obviously reduce the working efficiency of wind-driven generator.
Summary of the invention
Keep when making blade rotation the down wind blade vertical with wind direction, increase the Driving force of wind to the down wind blade, reduce the resistance that to blade wind is produced against the wind simultaneously, the utility model utilizes one group of planetary gear, when realizing blade rotation, the down wind blade surface is vertical with wind direction all the time, and is parallel with wind direction all the time to blade against the wind.
The technological scheme that the utility model is taked is: utilize one group of planetary gear, wherein
Structurally,
The beneficial effects of the utility model are when blade rotation, to keep the down wind blade vertical with wind direction all the time automatically, parallel to blade against the wind with wind direction, thereby increase the thrust of down wind blade, reduce contrary wind, improve the working efficiency of wind-driven generator to the blade resistance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the side-looking structural drawing that blade is aimed at the wind-driven generator of wind direction automatically, among the figure, and the 1-pedestal, the 2-generator, 3-generator shaft driving gear, 4-blade rack gear, the 5-blade gear, 6-bayonet lock, 7-blade rack, the 8-intermediate drive gear, the 9-wind vane, 10-wind vane gear, 11-stationary axle, 12-intermediate drive gear axle, the 13-blade.
Accompanying drawing 3 is a wind vane side-looking structural drawing, among the figure, and the 5-blade gear, the 10-wind vane, the commutation of 14-blade is sliding fast, 16-blade commutation retaining, 17-wind vane axis hole.
Embodiment
In Fig. 1, generator 2 is fixed on the pedestal 1, and generator shaft driving gear 3 is meshed with blade rack gear 4.Be fixed with the axis hole of intermediate drive gear axle 12 and blade 13 on the blade rack 7, blade rack 7 and wind vane 9 are coaxial, rotate around stationary axle 11.Wind vane 9 and wind vane gear 10 are one, and wind vane remains identical with wind direction.Blade gear 5, intermediate drive gear 8 and wind vane gear 10 are meshed, and bayonet lock 6 is in the same place blade 13 and blade gear 5 relative fixed, and blade 13 is rotated with blade gear 5.When bayonet lock 6 was not in pin hole, blade 13 and blade gear 5 can relatively rotate.
In Fig. 2, wind direction is from bottom to top, and blade rack 7 rotates counterclockwise around stationary axle 11.The size of blade gear 5 and the number of teeth and wind vane gear 9 are identical, and the intermediate drive gear 8 on the blade rack 7 only plays gearing.When blade rack 7 rotated around stationary axle 11, blade gear 5 was identical with the angle that blade rack 7 turns over around the angle that wind vane gear 10 turns over, and direction of rotation.Like this, when bayonet lock 6 is fixed together blade gear 5 and blade 13, blade 13 will remain a constant angle with wind vane 10.When this angle is 90 °, blade is vertical all the time with wind direction.Blade commutation sliding fast 14 has an inclined-plane, and when blade 13 rotated, an end of bayonet lock 6 contacted with sliding fast 14 inclined-planes of blade commutation, and blade commutation sliding fast 14 promotes bayonet lock 6 and withdraws from pin hole.Because the axle of blade 13 is not in the central authorities of blade, in case bayonet lock 6 withdraws from pin hole, blade 13 transfers to wind equidirectional under the wind-force effect automatically.Because bayonet lock 6 withdraws from pin hole, blade 13 and blade gear 5 can freely rotate, when contrary wind blade 13 always with wind in the same way.
In Fig. 3, with wind vane 9 all-in-one-piece blades commutation retaining 16, its turning shape guarantees that the rotation of blade gear 5 is not interrupted.When blade 13 forwards the lower end to, blade commutation retaining 16 will promote blade 13 and clockwise rotate, make blade 13 from identical with wind direction become vertical with wind direction.When blade 13 was vertical with wind direction, bayonet lock 6 was also just in time aimed at pin hole.Under the effect of bayonet lock spring 16, bayonet lock 6 enters pin hole, and blade 13 and blade gear are retightened together.
Claims (4)
