On described link arm 5, be provided with the first limiting stopper 9 and the second limiting stopper 10 that lay respectively at tail vane bar 2 both sides, in the present embodiment, the side that the rear end of link arm 5 tilts at tail vane rotary sleeve 8 arranges the first limiting stopper 9 on the right side, the contrary side that link arm 5 tilts at tail vane rotary sleeve 8 keeps left on side sidewall the second limiting stopper 10 is set, on described tail vane bar 2, be provided with limiting board 21, limiting board 21 can be arranged on the bottom of tail vane bar 2, when the first limiting stopper 9 and limiting board 21 butt, tail plate 3 is mutually vertical with the surface of revolution of blade 7, the surface of revolution of the blade 7 at this place refers to the surface of revolution of blade 7 in the time driving the motion of the inner formation magnetic force line cutting of generator 6, when link arm 5 is in the time that tail vane bar 2 rotates drive the second limiting stopper 10 with limiting board 21 butt, tail plate 3 is parallel to each other with the surface of revolution of blade 7, the angle Z=90 ° that now the relative tail vane bar 2 of link arm 5 turns over, as shown in Figure 6.
According to factors such as the length of the weight of the size of blade 7, tail vane bar 2 and tail plate 3 and tail vane bar 2, described link arm 5 is the eccentric to the left preferred y=30 ~ 100mm of distance of driftage rotary seat 4 relatively, the angle θ that the relative link arm 5 of described tail vane rotary sleeve 8 tilts to the right is preferably set to 8 ~ 15 °, in the present embodiment, link arm 5 is the eccentric to the left 65mm of driftage rotary seat 4 relatively, and the relative link arm 5 of tail vane rotary sleeve 8 tilts 12 ° to the right.
As the present embodiment further preferably, after described link arm 5 is in the past high, the low relatively described driftage rotary seat 4 of mode was obliquely installed, the link arm 5 relatively angle of inclination of driftage rotary seat 4 is preferably 3 ~ 5 °, preferably 4 °, be angle X=85 ° ~ 87 ° between link arm 5 and driftage rotary seat 4, preferably 86 °, as shown in figure 10; Relative link arm 5 driftage rotary seat 4 is obliquely installed, make the blade 7 that is arranged on link arm 5 front ends to facing upward, this structure can reduce vibration and the noise of blade 7 in the time rotating greatly, the wearing and tearing between the component that reduce to bring because of vibration etc., the working life of improving wind-driven generator.
In the present embodiment, the bottom of described link arm 5 is provided with stiffening plate 51, and the rear end of stiffening plate 51 is fixedly connected with driftage rotary seat 4, and stiffening plate 51, for improving the intensity of link arm 5, is avoided stressed bending deflection, affects normal power generation and even damages unit.
Working principle of the present utility model is as follows: the arrow A in figure represents wind direction, due to the link arm 5 eccentric installation of driftage rotary seat 4 relatively, blade 7 can produce eccentric moment windward time, it is the side trend that left side rotate of rotating shaft to link arm 5 bias that this eccentric moment makes have the to go off course center line B of rotary seat 4 such as blade 7 and link arm 5, as shown in the arrow C in Fig. 4; While supposing that blade 7 windward under the effect of eccentric moment, blade 7 drives link arm 5 to rotate to the left an angle, as shown in Figure 5, tail plate 3 is no longer parallel with wind direction A with the rotation of link arm 5, wind has active force to tail plate 3, tail plate 3 and tail vane bar 2 are had to the eccentric side of link arm 5 trend that rotate in left side, as shown by arrow D; Because tail vane rotary sleeve 8 is to tilt to be laid on link arm 5, when wind speed hour, eccentric moment is not enough to promote tail vane rotary sleeve 8 with the suffered wind-force of tail plate 3 and rotates relative to link arm 5, the suffered wind-force of tail plate 3 makes tail vane bar 2 can overcome the rotation that link arm 5 brings because of bias, tail plate 3 turns to the keeping parallelism with wind direction A under wind-force effect, makes blade 7 fronts rotary electrification windward;
In the time of change of the wind, if wind direction is by the left side side-blown of turning right, the rotation of turning right of tail plate 3 and tail vane bar 2, because of the effect of limiting board 21 and the first limiting stopper 9, making link arm 5 and tail vane bar 2 follow 4 interlocks of driftage rotary seat rotates, until that tail plate 3 turns to is parallel with new wind direction, now blade 7 fronts windward; If the wind direction after changing is the side-blown of being turned left by right side, turn right and be obliquely installed because of the relative link arm 5 of tail vane rotary sleeve 8, less wind speed is not enough to order about tail vane rotary sleeve 8 and rotates relative to link arm 5, therefore link arm 5 and tail vane bar 2 are also followed 4 interlocks of driftage rotary seat and are rotated, until tail plate 3 is parallel with new wind direction, blade 7 windward, has been realized by tail plate 3 automatic capturing wind directions in blade 7 fronts.
In the time that wind speed exceedes predefined value as 12m/ second, tail vane rotary sleeve 8 rotates relative to link arm 5 under the effect of eccentric moment and tail plate 3 suffered wind-force, thereby change the angular dependence between blade 7 and tail plate 3, blade 7 tail plate 3 relative to generator 6 turns to bias one side of link arm 5, changed wind-force and cut out direction on blade 7, reduced blade 7 windward, lifting surface area, wind diminishes to the active force of blade 7, blade 7 rotating speeds progressively reduce, and have realized the automatic speed regulation of blade 7;
In the time that wind speed exceedes predefined value as 14m/ second, blade 7 tail plate 3 relative to generator 6 turns over 90 ° to bias one side of link arm 5, as shown in Figure 6, now, tail plate 3 is parallel with wind direction A, blade 7 is also driven to parallel with wind direction A, blade 7 no longer front windward but side windward, wind no longer produces active force in the front of blade 7, the continuation rotating speed of blade 7 progressively reduces even and stops operating, the driving phenomenon of effectively having avoided blade high speed rotating and produce, realize complete wind sheltering, the parts such as blade can be effectively protected and unlikely damage in high wind,
In the time that wind speed reduces, because tail vane rotary sleeve 8 tilts to be laid on link arm 5, tail vane bar 2 and tail plate 3 automatically reset under Action of Gravity Field, in the process resetting, tail plate 3 is subject to wind-force effect because of not parallel with wind direction A, tail vane bar 2 promotes link arm 5 and rotates to the right gradually, make blade 7 gradually windward, in the time that tail vane bar 2 and tail plate 3 are reset to as shown in Figure 4 state completely, limiting board 21 on tail vane bar 2 and the first limiting stopper 9 butts, tail plate 3 is mutually vertical with the surface of revolution of blade 7, tail plate 3 and tail vane bar 2 are with the normal wind direction that catches of moving vane 7 again.
In the present embodiment, described limiting board 21 is the plate of the L-shaped shape in cross section, and a L limit of limiting board 21 is used for and described the first limiting stopper 9 butts, and another L limit is used for and described the second limiting stopper 10 butts, is provided with and strengthens corner block 23 between two L limits.Impact force while reset for reducing tail vane bar 2 and the vibration bringing, the first limiting stopper 9 described in the utility model is yielding rubber, thereby realizes reset soft landing.
The utility model, in the time that solution is resisted high wind and attacked, provides a kind of simple and reasonable compactness, and easy for installation, implementation cost is low, can realize automatic adjusting vane rotating speed according to wind speed, avoid occurring the wind-driven generator yaw device of driving phenomenon.
The above, be preferred embodiments of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
