It is placed on circular tune in angle of attack chute 13, to roll rotation, this structure makes the blade 4 of all positions in a working circumference all keep phase
The same angle of attack, produces constant output torque.In figure is visible, and the more favourable standard round of spheric rotating disk 11 adjusts angle of attack chute 13 left/right rotation
Move to adjust attack angle of blade it will be appreciated that, in some other embodiment, this sphere sabot be alternatively taper sabot or flat
Disk.
It is provided with traveller 40 on described tune angle of attack guide rail, described rotating disk is provided with the arc corresponding with described traveller 40
Chute 41, described arc chute 41 includes the multi-section circular arc connected in star with output shaft 1 as the center of circle, or recessed for whole circle
Groove, described traveller 40 is corresponding to be arranged in described arc chute 41.
In the present embodiment, below tune angle of attack chute 13 and on the circumference of the suitable diameter with output shaft 1 as the center of circle just

It is slidably matched on the circumference of same diameter and in corresponding one section of arc chute 41；In the suitable position adjusting angle of attack chute 13 side
Put rigidity link to rotate screw rod 15 by motor 14 and push away nut push pedal 17 that (drawing) is moved.
Due to adjusting angle of attack chute 13, multiple travellers 40 and the arc chute 41 being slidably matched therewith are arranged at defeated below
Shaft 1 is the center of circle, on same radius circumference, when motor 14 rotate screw rod 15, push away (drawing) move nut push pedal 17 mobile when, you can band
Dynamic tune angle of attack chute 13 is overall to rotate (see Fig. 2 a) around output shaft 1；After the position adjusting angle of attack chute 13 changes, make roller
9 drive tune angle of attack crank 8 and blade 4 to produce new pendulum angle around axis of runner blade 5, reach all positions of adjusted in concert working circumference
The purpose of blade 4 angle of attack, change wind energy conversion system moment and rotating speed put.
This structure is advantageous in that：The intersection location of the upper and lower windward semicircle in a working circumference for the blade 4 is not required to change
Becoming angle of attack angle, thus decreasing the resistance that attack angle of blade change brings, so that smooth running, rotating speed is improved.Certainly, circular tune is attacked
Angle chute 13 and roller 9 are such as used magnetic levitation technology instead and are slidably matched and can reduce rotary resistance.
See Fig. 1, Fig. 2, Fig. 7, in the present embodiment, wind energy conversion system includes spherical rotating disk 11 and to wind mechanism, this reality to wind apparatus
Apply that in example, this is wind tail vane 12 to wind mechanism；Guiding device includes arc deflector 20, inverted L shape connecting rod 18, clamp 19.Spherical
Rotating disk 11 is sleeved on frame axle sleeve 2 outside by bearing and independently can rotate around axis 1；The circle of the spherical shape of sphere rotating disk 11
The heart and radius are to be formed by three swing position on a cross section for the roller 9；Spherical rotating disk 11 leeward semicircular edge
A kind of shape of outer connection is narrower and wind tail vane 12 that extend up to blade upper end along outside blade 4, wind tail vane 12 horizontal edge
It is inserted perpendicularly into above bracing frame 3 and in the pit 21 of output shaft concentric to the direction in the output shaft center of circle 1 one end that is rigidly connected
Inverted L-shaped connecting rod 18；Inverted L-shaped connecting rod 18 vertical section blade height built with clamp 19, be embedded between clamp 19 several pieces to
The arc deflector 20 of the blade direction of rotation bending of leeward semicircle.Because inverted L-shaped connecting rod 18 lower end is inserted perpendicularly into pit 21
In rolling bearing, upper end and wind tail vane 12 be to be rigidly connected, therefore deflector 20 and sphere rotating disk 11 can by wind tail vane 12 draw with
Step swings, the change of reply wind direction.Certainly, deflector 20 can also adopt the other technologies mode such as electronic sensor adjust angle,
And other installing and fixing method, thus reducing wind tail vane weight or L-shaped connecting rod being abandoned.
Fig. 2 is 1 group of blade in the angle of 6 diverse location angles of attack and the in good time course of work adjusting attack angle of blade.See figure
2a, slides because traveller 40 inserts in arc chute 41, when motor 14 rotates screw rod 15 and then pulls nut push pedal 17, makes tune
Angle of attack chute 13 rotates counterclockwise around output shaft 1.Under the drive of the roller 9 now rolling in adjusting angle of attack chute 13, adjust the angle of attack
Crank 8 and blade 4 swing around axis of runner blade 5, and blade 4 angle of attack synchronous adjustment of all for working circumference positions is larger negative attacks
Angle, about -20 ° of the angle of attack on figure.Now in working circumference, front half cycle (Fig. 2 a left side) produces counter clockwise direction driving force to blade 4 windward
Square；When blade 4 turns to working circumference second half (on the right of Fig. 2 a) windward, blade 4 still be the identical angle of attack, on figure the angle of attack about-
20°.But the guiding due to arc deflector 20, makes wind change and flows (see Fig. 9) to blade 4 direction of rotation, according to air force
Principle, equally produces counter clockwise direction driving moment in the blade 4 of leeward semicircle.
As Fig. 2 b, when wind energy conversion system needs to reduce rotating speed or moment, rotated screw rod 15, promoted nut push pedal by motor 14
17, make tune angle of attack chute 13 around output shaft 1 rotationally clockwise.Now, the tune angle of attack chute 13 that position changes guides
Roller 9 and tune angle of attack crank 8 drive working circumference with axis of runner blade 5 for the center of circle, and this blade 4 produces new pendulum angle, by leaf
The angle of attack windward of piece 4 suitably diminishes, and in the forward and backward windward semicircle position of working circumference, the angle of attack is all reduced to about -12 ° windward, leaf
Piece 4 produces anticlockwise moment in working circumference to be reduced therewith, and rotating speed decreases.
As can be seen here, the round end leading edge 6 of the streamline vane 4 of wind energy conversion system of the present invention is always held at upwind side, and
There is the course of work twice in one working circumference, almost can produce driving moment in the same direction on all positions of circumference, and can
Rotating speed and moment are adjusted according to workload demand in good time, improves wind energy utilization, can more extensively adapt to the demand of different load.
In figure shows, just not produces driving force square when blade 4 is only near in figure highest and lowest point.
The wind energy conversion system of Fig. 3 explanation present invention course of work to wind apparatus in change of the wind.When wind direction is derived from Fig. 3 a
During figure left side (see solid arrow), now, parallel with wind direction to wind tail vane 12, make spherical rotating disk 11 transfixion, adjust the angle of attack
Chute 13 is in appropriate location, and blade 4 has the favourable angle of attack of output driving moment；When wind shift to Fig. 3 a lower left corner (see
Dotted arrow) when, lifting in trend is pushed to wind tail vane 12 wind-engaging, and drives sphere rotating disk 11, adjust angle of attack chute 13 and arc
Deflector 20 grade turns to the position of Fig. 3 b in the lump with output shaft 1 for the center of circle, stops turning when parallel with wind direction to wind tail vane 12
Dynamic.From Fig. 3 b, although wind direction has changed about 45 ° (see solid arrow), adjust angle of attack chute 13 and arc deflector accordingly
20 grade also concomitant rotation, but the angle of attack windward of blade 4 does not change, and still exports identical moment.So, the wind-force of the present invention
Machine automatic accurate can adapt to each side's always wind, do not affect the normal operation of wind energy conversion system completely in wind vector.
Certainly, other structures form also can be adopted to wind mechanism, for example, Figure 10 is that the wind energy conversion system of the present invention adopts leeward formula
Structural representation.This includes the swing mechanism making vertical axis windmill integrally carry out swinging downwind, this swing mechanism to wind mechanism
Including the axle sleeve 33 being fixedly connected on rotating disk windward edge side, and the swing that one end is arranged in axle sleeve, the other end is fixing
Axle 34.This structure has abandoned phoenix tail rudder, can simplify structure.
Fig. 4 illustrates a kind of wind energy conversion system of the present embodiment guiding pair handle structure and operation principle.See shown on the left of Fig. 4 a, in leaf
Piece 4 goes in figure left-most position, when roller 9, axis of runner blade 5 and 1 three points of output shaft point-blank when, roller 9 this moment
Constraining of modulated angle of attack chute 13 delayed or forward swing situation (see arrow) can not be occurred for axle center with axis of runner blade 5.Work as leaf
Piece continues to turn to forward Fig. 4 a lower-left Angle Position in fact it could happen that two kinds of angles of attack：The blade of in figure chain-dotted line performance is because of roller 9
The angle that forward swing is formed, this is harmful angle of attack；The blade of in figure solid line performance is because of the angle of the delayed formation of roller 9, and this is to have
The sharp angle of attack.
For overcoming above deficiency, need roller 9, axis of runner blade 5 and 1 three points of output shaft point-blank when, by leaf
Piece 4 is to the correct angle of attack " stirring " once.I.e.：In axis of runner blade 5 lower end, perpendicular rigid above angle of attack crank 8 is adjusted to connect and leaf
The lead angle pair handle 10 of the piece string of a musical instrument 7 about parallel (or other, possible angle that be avoided that three point on a straight line vertical with adjusting angle of attack crank 8)
(see Fig. 4, Fig. 1, Fig. 7), and on sphere rotating disk 11, adjust appropriate location setting lead angle slide block 22 on angle of attack chute 13 side with
Lead angle pair handle 10 is slidably matched (see Fig. 4 b).See on the right side of Fig. 4 a, when blade is in the position near 3 points of straight line, lead angle pair
Handle 10 and lead angle slide block 22 sliding contact, because the stop of lead angle slide block 22 forces blade 4 to swing to suitable angle；Work as roller
9 cross this harmful position, lead angle pair handle 10 and after lead angle slide block 22 disengages, roller 9 and adjust angle of attack crank 8 will play once again
The effect (see Fig. 4 a upper right corner, Fig. 4 b) of the guide blades angle of attack.See Fig. 2, left and right side on sphere rotating disk 11 for the lead angle slide block 22
Set position is different.
Fig. 5 is the design using another kind of tune angle of attack crank 8 for the present invention, adjusts angle of attack crank 8 to be that a kind of flexible connection guides
The structural representation of crank 8.The wind energy conversion system of foregoing V-type layout blade 4 is rigid vertical and blade because adjusting angle of attack crank 8
Axis 5 connects, and so that tune angle of attack chute 13 etc. is necessarily placed at and adjusts on angle of attack crank 8 approximately parallel ball cone inclined-plane, Ci Zhongbu
Office may make troubles to the making and installation of adjusting angle of attack device.For this reason, proposing one kind by axis of runner blade 5 and to adjust angle of attack crank 8
Rigid attachment be changed to form by bearing pin 23 chain connection；It is designed as adjusting angle of attack chute 13 plane device and is arranged on plane
Work on rotating disk 24.This kind of method of attachment can make tune angle of attack crank 8 swing up and down around bearing pin 23, still can be by tune angle of attack crank 8
Blade 4 is driven to rotate to adjust the angle of attack around axis of runner blade 5.
Fig. 6 is a kind of wind energy conversion system of H type layout, has that structure is simple, make easy feature.But exist and adjust angle of attack chute
It is relatively large in diameter, roller 9 rotation path is longer, roller 9 may be increased and wear away.If using magnetic levitation technology by roller and the tune angle of attack
Slide coordinates, can reducing friction resistance.
Certainly, blade layout also can be in reverse V-shaped, H type, U-shaped, φ type etc..
Fig. 8 is that the wind energy conversion system of the present invention adjusts the cooperation pair of angle of attack crank to adjust angle of attack sliding groove structure schematic diagram using double.Fig. 8 a says
The course of work of eight diverse locations in working circumference for the bright 1 group of blade；This structure eliminates tune angle of attack pair handle 10 and lead angle is slided
Block 22, simplifies structure.In Fig. 8, blade rotor 5 lower end about perpendicular rigid connects two tune angle of attack cranks 8 being mutually about 90 °.
One of adjust angle of attack crank 8 ending vertical downwards equipped with higher roller 26, it is 27 have relatively that higher roller 26 is placed in the center of circle
Deep tune rolls cooperation in angle of attack chute 28；Another adjusts angle of attack crank 8 ending vertical downwards equipped with shorter roller 29, shorter roller
29 are placed in rolling cooperation in the shallower tune angle of attack chute 31 that the center of circle is 30.See Fig. 8, relatively deep tune angle of attack chute 28 is attacked with shallower tune
Angle chute 31 is integrally provided on sphere rotating disk 11 for one, and to adjust leaf by motor control around the overall left-right rotation of output shaft 1
The angle of attack of piece 4.
Put into rolling, shorter roller 29 in relatively deep tune angle of attack chute 28 tune because of higher roller 26 and put into shallower tune angle of attack chute
Roll in 31, so that high and low roller is taken their own roads, not interfere with each other；And because two are adjusted angle of attack crank 8 to be mutually about 90 °, if wherein
One roller and blade rotor 5, output shaft 1 point-blank when, because the tune angle of attack crank 8 of another about 90 ° of difference is inevitable
