Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described and describes.

The utility model is made of support mechanism, movable wing linking mechanism, speed limiting mechanism, position-limit mechanism and auxiliary starting device.

1) support mechanism: the main body 2 of support mechanism is cylindric, vertically is installed on the upper end of pto 1, and both shaft axiss overlap.The cantilever of four groups of (two every group) supportings of distribution rachis is installed bearing shell 10 and is slidingly matched with rachis in the cantilever on the cylindrical of support mechanism main body 2.Seal ring 12 is installed in the cantilever outer end, invades in the support mechanism to prevent water part and sand and dust.At the casing of the inner bottom surface mounting support linkage gear of support mechanism main body 2, end cap is installed at the top of casing, and its purpose one is the intensity that can increase casing, and the 2nd, in order to support auxiliary starting device.

The shaft axis of the shaft axis of symmetrical two groups of cantilevers and support mechanism main body 2 is in same vertical plane; About the shaft axis of relative two cantilevers overlap, thereby the shaft axis that makes the two opposite groups cantilever forms two horizontal lines up and down, the shaft axis of four groups of cantilevers forms four horizontal lines, divide and be on two vertical planes, these two planes intersect vertically on the shaft axis of support mechanism main body 2 again, but four horizontal lines and non-intersect, wherein the intersection point of the shaft axis of one group last horizontal line and support mechanism main body 2 is positioned at the mid point of two intersection points of another shaft axis of organizing horizontal line and support mechanism main body 2; Two horizontal distances depend on the pitch diameter of linkage gear up and down.

2) movable wing linking mechanism: the movable wing linking mechanism is that the utility model is different from the crucial part of various Vertical shaft machines in the past, its innovative point is: not only two blades of one group of movable wing can link mutually, and symmetrical two groups of movable wings also can link mutually.

Shown in Fig. 2,3,

rachis

6,7 and

linkage gear

4,5 are associated with spline.When overlooking, wind energy conversion system turns clockwise, and blade 29 is to be installed on the rachis 6 to tilt 45 ° angle of lower right, and blade 30 is to be installed on the rachis 7 with 45 ° the angle of tilting to the upper right.Four groups of movable wings all are to install in this way, form four wings shown in Figure 1 and all become 90 ° of angles, the forward form of Pai Lieing.Since about relative two rachises simultaneously related with same linkage gear, like this, when one group of wing during with the wind angle be 180 °, the angle of another group wing of its symmetry just becomes 0 °.This structure is containing the unstable equilibrium principle, following horizontal about two blades at ordinary times always with State keep balance, and go up horizontal about two blades be forced into

State, and this state of equilibrium is extremely unsettled, under the essentially identical situation of the leaf weight of two wings, the whichever wing is subjected to some effect of external force, the angle of two wings will change immediately, and the torsion that increases both wings is poor, and the power of rotation is provided for the utility model.

The pitch diameter of

gear

4,5 is identical, is slightly larger than 1.5 times of diameter of gear shaft, has enough gaps that in another group linkage gear one is installed so that be in 4,5 liang of between centers of gear of engagement; Rachis 6,7 penetrate from the cantilever outer end and related with linkage gear, regulate its position and use nut 16 by

tension spring

14,17 lockings, guarantee that rachis neither produces axial float at ordinary times, can rotate flexibly again, for avoiding frictional force between tension spring 14 and the support mechanism main body 2 to influence the rotation of rachis, between tension spring 14 and support mechanism main body 2, be added with thrust-bearing 13, again because support mechanism main body 2 is cylindric, so between thrust-bearing 13 and support mechanism main body 2, be added with

pad

8,8 inboard is vertical with rachis, and the outside then is the cambered surface with the inwall identical radian measure of support mechanism main body 2.The utility model is when state of rest, and two blades of every group of movable wing become 90 ° of angles, its front end gap that do not have in the horizontal direction, like this, when the afterbody wind-engaging of movable wing, air can produce eddy current between two blades, thereby opens the subtended angle of two blades rapidly.For reaching this purpose, will guarantee two blades when angle is 180 °, not in same vertical plane.Upper blade can be installed in the place ahead of rachis, and lower blade is installed in down the rear of rachis, like this, when leaf angle was 0 °, two blades all were in the top of rachis separately.When two leaf angles are 90 °, its front end lap in the horizontal direction is the smaller the better, like this, be in the wind energy conversion system in the state of rest, the wing one opens angle a little with the wind, the wing just becomes the front end open state at once against the wind, the wing continues to open under the effect of eddy current with the wind, and the inboard of middle two blades in other words conj.or perhaps of two blades of the wing forms eddy current equally against the wind, but the effect that this eddy current causes is that two blades are closed up, so, reach maximum rapidly along the pressure difference of contrary wind both wings.Seal ring 12 should have suitable distance with the bearing shell of cantilever outer end, the axially outer critical distance that moves when this distance is greater than the rachis speed limit.In order to avoid seal ring falls into the venturi portion of rachis.

3) speed limiting mechanism: speed limiting mechanism of the present utility model is exactly the spline that rachis is associated with linkage gear, and this spline is not general straight key, but has the taper key of certain angle of deflection.

As Fig. 1, the angle of deflection of the spline of two rachises up and down of described every group of movable wing is anti-phase, and the spline of last rachis is left-handed, and the spline of following rachis is dextrorotation.Like this, when the rotating speed of wind energy conversion system transfinites, rachis outwards is subjected to displacement greater than the tension force of tension spring 14 owing to centrifugal force, consequently the blade subtended angle diminishes, but the wing is because the effect of limit stoper against the wind, its angle still is 0 °, so diminish along the torsion difference of contrary wind both wings, the rotating speed of wind energy conversion system has also just slowed down.Thereby know by inference, the rachis displacement will cause all being 0 ° along the angle of contrary wind both wings that like this, whatsoever other wind of level can not make wind energy conversion system rotate yet.

The helical pitch of the oblique spline of described rachis can not be too small, if too small, will take place forward to slide, thereby influence the speed limit effect; But also can not be excessive, in order to avoid need bigger displacement for speed limit, thus increased the volume of support mechanism main body; The sphere of activities of blade only is 90 °, so the operating range of linkage gear also only is 90 °, as shown in Figure 3.But, if because the needs of Gear Processing technology and auxiliary starting device also can be processed into full circle fully.

4) limit stoper: limit stoper 28 is exactly one The shape frame is installed in the afterbody of upper blade, because the restriction of this framework can not be further closed the time, two blades all become level when two blades, and promptly the closed angle of the wing is 0 ° against the wind, the windage minimum.

5) auxiliary actuating apparatus: auxiliary actuating apparatus is by wind vane 27, wind vane vertical shaft 22, and ball bearing 20,25, seal ring 26,

roller

18,23, direct dialing bar 17, special-shaped driving lever 21 and end cap 19 are formed.

When the utility model rotated in weak wind, the wing need have a bigger angle with wind direction with the wind, just can open the subtended angle of blade.And against the wind the wing rotated to axially over against wind direction when (claiming " standard is the wing with the wind "), and the wing opens up into 180 ° from 0 ° immediately against the wind.Like this, as long as produce angle with wind direction, the wing begins acting immediately with the wind.And the standard in the weak wind with the wind the wing can only lean on self weight its try to achieve temporary transient stable, at this moment can be considered no external force effect, so its angle can only open up into 90 ° from 0 °, and the wing will be opened for 180 ° by 90 ° with the wind, just also must continue rotation, up to having one than mitre with wind direction, could thoroughly open, and this process will forward one drive of the wing with the wind, and this also just means has wasted quite a few wind energy, so the utility model has designed auxiliary starting device.Can know by accompanying drawing 2, roller 23 is installed on the vertical shaft 22 of wind vane 27, special-shaped driving lever 21 is installed on end cap 19, give 21 counterweights, make its assembly erectility at ordinary times, driving lever 17 is installed, when leaf angle is 0 ° on rachis on every group of movable wing, direct dialing bar 17 contacts with the scroll wheel 18 of special-shaped driving lever 21 lower ends, like this, when wind energy conversion system rotates, because wind vane does not rotate, so, just there is one group of against the wind wing wing with the wind that becomes to be as the criterion in every 1/4 week of rotation of wind energy conversion system, and driving lever 21 beginnings of this wing contact with roller 23, and stirred by 23 and to be tilted to the right, scroll wheel 18 then drives direct dialing bar 17 and is tilted to the left, so blade 29, angle between 30 just is opened, rather than fully by wind-force acting on the wing with the wind open angle, so just shift to an earlier date the time of opening, improved wind energy utilization.

One wind vane is installed on the body end cap, and the shaft axis of its vertical support axle overlaps with the shaft axis of main body, and related with body end cap by ball bearing, and the lower end is associated with the end cap of linkage gear supporting frame in the main body by ball bearing; Frame end has covered four axle sleeves, its shaft axis respectively with the shaft axiss of four groups of rachises in same vertical plane, install in the axle sleeve

The horizontal component of the special-shaped driving lever of shape, and can freely rotate; One is long and the other is short for two vertical bars of special-shaped driving lever, stock is near the vertical support axle of wind vane, quarter butt is positioned at the outside of framework, a horizontal axis roller is installed in the lower end of quarter butt, the shaft axis of its shaft axis and horizontal component is in same vertical plane, and be positioned at the quarter butt outside, special-shaped driving lever makes it do the time spent in no external force through counterweight always to be erectility; The wind vane vertical shaft is at the suitable height (high more good more) and the equidirectional installation one horizontal axis roller of wind vane arrow of body interior; Driving lever is always installed in the appropriate location of rachis on four, and this driving lever and blade are at an angle of 90;

The angle that should remain to two blades between described driving lever 17 and the roller 23 opens up into suitable degree and could break away from, and comparatively speaking, open angle is the bigger the better.For the sensing that guarantees wind vane is not subjected to the influence of driving lever 21, it is big that the empennage of wind vane should be tried one's best; Described roller 23 on vertical shaft 22 with the arrow of wind vane 27 in the same way, but in fact a suitable advancement amount can be arranged, when this advancement amount became to be as the criterion with the wind the wing for the wing against the wind, leaf angle opened and is 90 ° and is advisable; Rachis arrives to a certain degree owing to speed limit produces displacement, and direct dialing bar 17 will break away from roller 18.

Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
