Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figures 1 to 3, a kind of wind wheel structure of vertical-axis wind driven generator, described wind wheel 1 is made of the blade 11 more than two, wind wheel of the present utility model is made of two symmetrically arranged blades 11, and wind wheel 1 is Φ shape, and shown in Fig. 6,7, wind wheel can also be H shape.Described blade 11 is connect by the above blade unit series winding of two joints and forms, in the present embodiment, described blade 11 is formed by connecting by three joint blade units 111,112,113, comprise upper blade unit 111, Leaf unit 112 and lower blade unit 113, upper blade unit 111 and lower blade unit 113 symmetries; And upper blade unit 111 and lower blade unit 113 be section linearly, and Leaf unit 112 is arc; As shown in Figure 4, the connecting end of every joint blade unit is provided with adpting flange 2, and described adpting flange 2 is provided with screw 21, connects by bolt between the blade unit.The cross section of described blade unit is water-drop-shaped small in ends broad in the middle, and wherein a wherein end small in ends is nose circle, and the other end is most advanced and sophisticated, and the shape of described adpting flange 2 is similar to the sectional shape of described blade unit.As shown in Figure 5, described blade unit comprises inner skeleton 4 and the protecting jacket 3 that is wrapped in outside the described skeleton 4; Described protecting jacket 3 is metalwork, adopts riveted to be connected between protecting jacket 3 and the skeleton, makes between protecting jacket 3 and the skeleton to fit tightly, and protection skeleton 4 is avoided damage.Described skeleton 4 is formed by connecting by plural aluminum alloy framework assembly 41, skeleton component 41 in the present embodiment is made of ten skeleton components 41, the junction surface of skeleton component 41 is provided with two semicircular shrinkage pools 411, after adjacent two skeleton components 41 combine, just can form the shrinkage pool of two circles at the junction surface place, then in circular shrinkage hole, lock bolt 5 and just two adjacent skeleton components 41 can be connected; The bolt 5 at this place not only can play connection function, and can play positioning action, prevents that interconnective skeleton component 41 from misplacing; Because being shaped as of blade 11 is irregular, so the shape of the skeleton component 41 in the blade is all different, combines to form the blade profile of water-drop-shaped.
