Each component Function and operation of the present invention:

(1) the blades installation plate 1: fan blade 20 be used for to be installed, and to be connected connection with sleeve.

(2) sleeve 2(Fig. 6): be connected with blades installation plate 1, can in the several angle scope, rotate freely around axle 6, and the moment of torsion that blade 20 is subject to is passed on the torsion spring 4, realize becoming established angle W(Fig. 1).Sleeve 2 internal upper parts are provided with for limiting radial bearing 3 axially movable steps, the bottom has for the M1 tapped hole that holding down bolt 5 is installed and M2 tapped hole and is used for Φ 3 through holes that torsion spring 3 is located, and outer step is provided with for Φ 4 through holes that fan blade is installed.

(3) radial bearing 3: be used for to realize freely rotating between sleeve 2 and the axle 6, make winding machine change inclination angle S(Fig. 1) function of speed governing.Also be used for and holding down bolt 5 limits the position of sleeve 2 together, make its not can to when wind energy engine is worked owing to the reasons such as centrifugal force are deviate from axle 6.

(4) torsion spring 4: when the moment of torsion that blade 20 is subject to causing because of wind-force is worked torsion less than torsion spring 4, torsion spring 4 is in relaxation state, when blade 20 is subject to the moment of torsion that causes because of wind-force greater than torsion spring 4 Operating torque, deformation occurs in torsion spring 4, and the established angle of blade 20 is reduced.Once wind-force reduces, because the active force of torsion spring 4 makes sleeve 2 rotations, blade 20 established angles revert to initial value.Regulate fan blade 20 established angles by torsion spring 4, make wind speed round constant within the specific limits.
