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° |
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.
