Technical field

The utility model relates to a kind of rectilinear soft blade angle and adjusts wind force power machine automatically, mainly is made up of main shaft, blade, sprocket wheel, wind direction empennage and chain.

Background technique

The mode that utilizing wind-force to carry out electric power provides has been used for many years, and the rotating manner of traditional wind force power machine has modes such as vertical shaft and horizontal axis.Fig. 1 is the stereogram of perpendicular axis type wind force power machine commonly used, as seen from the figure, be fixed with blade 8 on the vertical axis type wind power engine main shaft 7 commonly used, this vertical axis type wind power engine blade 8 is two stator blades, the shape of blade 8 has the mode of arc shape plate, drives blade 8 rotations by wind-force; Therefore this stator blade 8 must can't obtain preferable efficient in the face of the wind direction of different direction when a circle, blade 8 adopts hard mostly, generally constitutes with glass fibre or carbon fiber, therefore whole manufacture cost height; Fig. 2 is the stereogram of horizontal shaft type wind force power machine commonly used, as seen from the figure, be fixed with bearing 11 on the horizontal shaft type wind force power machine main shaft 9 commonly used, bearing 11 front end axles are established an impeller shaft 12, be fixed with 3 groups of blades 10 on the impeller shaft 12, this blade 10 is three blade modes, mostly is shaft-like or the pin taper, and box haul drives blade 10 rotations and makes impeller shaft 12 be rotated synchronously simultaneously; These blade 10 box hauls change and rotate, and till the face windward slope, and velocity modulation is put in order angle with the wind, owing to blade is rigid and is shaft-like or pin taper, therefore can't adjust the angle of blade.

The model utility content

The technical problems to be solved in the utility model provides a kind of rectilinear soft blade angle and adjusts wind force power machine automatically, and no matter how wind direction changes, and all can adapt to, and does not need to do in addition the steering gear.

For solving the problems of the technologies described above, the utility model mainly is made up of main shaft, blade, sprocket wheel, wind direction empennage and chain, and described main shaft is outward extended with lower cross bar; Described blade upper and lower end has extended lower shaft; Described sprocket wheel is installed on the axle and the axle upper end of wind direction empennage on the blade respectively; Described chain connects the sprocket wheel on the sprocket wheel on the axle and the axle that is installed on the wind direction empennage on the blade.

Wherein, the sprocket wheel of the axle upper end of wind direction empennage is 1: 2 with the gear ratio that places the sprocket wheel of axle upper end on the blade.

Wherein, the leaf position and the angle of four and three maximum wind powers that blade obtained and maximum rotation effective torque are:

Leaf position	0°	90°	120	180°	240°	270°
Leaf position	0°	90°	120	180°	240°	270°	Blade angle	45°	90°	105	135°	165°	180°

Wherein, described blade adopts soft design, and its quantity is more than two, blade be shaped as shaped as frame, mast shape or complex.

Wherein, described chain strip adoption gear, the transmission of Toothed belt mode.

Rectilinear soft blade angle described in the utility model is adjusted wind force power machine automatically following technological merit: owing to adopt said structure, when wind force power machine turned round, wind direction empennage nature was towards the opposite direction of wind, at this moment, if wind direction is constant, whole fulcrum bar is fixing not to be rotated.Before being rotated, wind energy conversion system needs to adjust earlier the angle of blade, the blade of diverse location transfers to different angles, after treating that blade angle is adjusted, assemble each chain, make the axle interlock mutually of blade and wind direction empennage, when being subjected to wind blows, the related sharf of whole main shaft turns clockwise together, when blade arrives diverse location different blade angles is arranged then, this blade angle is best angle.Therefore, utilize the vertical shaft mode, no matter how wind direction changes, all can adapt to, not need to do in addition the steering gear, blade adopts soft, no matter left and right directions is all applicable, and blade all can change into best angle when different azimuth, and obtains maximum rotation effective torque.
