Embodiment Construction
[0033] Such as figure 1 As shown, the blade of the vertical axis wind turbine rotor provided by the present invention includes a skeleton forming the shape of the blade and a skin (not shown) fixed outside the skeleton, and the shape of the blade is a vertical columnar body , its horizontal section is the cross-sectional shape of the aircraft wing, that is, relative to the rotation axis 03 of the wind rotor (see Figure 6 , 7 ), the outer surface of the blade 01 facing outward is a streamlined arc surface, and the smooth transition between the outer surface and the opposite inner surface forms a larger windward end, that is, the head of the blade and a smaller tail.
[0034] Relative to the vertical axis of the wind rotor shaft 03, the distance between the outer surface and the inner surface of the cylinder basically gradually decreases from the head to the tail; in the vertical direction of the blade, each horizontal The cross-sectional size and shape are the same.
