As shown in Figure 5, become dip angle organization 101 and comprise spline shaft 9, rotating disk 10, cod 11, Compress Spring 12, spline shaft 9 is slidably connected rotating disk 10, and cod 11 is equipped with in rotating disk 10 front end, cod 11 is connected with casing 13 by Compress Spring 12, and rear end connects connecting rod 8.
The each component Function and operation of the present invention:
(1) blades installation plate 1: for installing fan blade 20, and be connected with sleeve 2.
(2) sleeve 2(Fig. 6): be connected with blades installation plate 1, can rotate freely within the scope of several angle around axle 6, and the moment of torsion that blade 20 is subject to is passed on torsion spring 4, realize becoming established angle W(Fig. 1).Sleeve 2 internal upper part is provided with the step moved axially for limiting radial bearing 3, Φ 3 through hole that bottom has M1 tapped hole for installing holding down bolt 5 and M2 tapped hole and locates for torsion spring 3, outer step is provided with Φ 4 through hole for installing fan blade.
(3) radial bearing 3: for realizing freely rotating between sleeve 2 and axle 6, makes mechanism realize becoming inclination angle S(Fig. 1) function of speed governing.Also for limiting the position of sleeve 2 together with holding down bolt 5, make its can not to when wind energy engine works because the reasons such as centrifugal force deviate from axle 6.
(4) torsion spring 4: blade 20 be subject to because of moment of torsion that wind-force causes be less than torsion spring 4 working torque forces time, torsion spring 4 is in relaxation state, when blade 20 is subject to being greater than torsion spring 4 Operating torque because of moment of torsion that wind-force causes, there is deformation in torsion spring 4, the established angle of blade 20 is reduced.Once wind-force reduces, due to the active force of torsion spring 4, sleeve 2 is rotated, blade 20 established angle reverts to initial value.Regulate fan blade 20 established angle by torsion spring 4, make wind speed round constant within the specific limits.
(5) positioning screwn 5: the connection and positioning completing sleeve 2 and axle 6 with radial bearing 3 together.
(6) axle 6: axle 6 has a through hole 15 be connected with positioning rod 7, positioning rod 7 is connected by bearing pin and axle 6 circular hole.Positioning hole 14 is torsion spring 4 positioning hole.The attachment hole 16 of axle 6 bottom is connected with connecting rod 8.As Fig. 7
