Document Type and Number:
WIPO Patent Application WO/2019/194180
Kind Code:
A1
Abstract:
Provided is a vertical shaft type wind power generator that is lightweight and simple in shape, and that is provided with blades by which rotational force is efficiently obtained. In a blade 4, a wing 42 made of a soft material is attached to a hard frame 41, which has the shape of a letter V when viewed from above and is provided so that the distal end portion of the V is a distal end along a rotational direction. V-shaped portions of the frame 41 are provided to the highest part of the blade and the lowest part of the blade, and the frame 41 is configured from a hard support pillar portion vertically (along the vertical direction) connecting the distal end portions of the V's of both the V shape of the highest part and the V shape of the lowest part. The wing 42 is shaped such that two isosceles-trapezoid-shaped objects, each of which has as an upper base a side having a length equal to the support pillar portion of the frame 41 and a lower base longer than the upper base in the opposite side, are joined together at the upper bases. The upper base portions are joined to the support pillar portion of the frame 41, and the leg portions of the isosceles trapezoids are attached to the V-shaped portions of the frame.
