<P>PROBLEM TO BE SOLVED: To stabilize operation of a blade corresponding to wind power with a simple structure, in a vertical shaft type wind power generator. <P>SOLUTION: This vertical shaft type wind power generator includes an arm 15 for connecting the base end 15A to the rotary shaft 8 side and arranging the tip 15B sideways to the rotational axis 9, and the blade 11 installed on the arm 15 and arranging the longitudinal direction in substantially parallel to the direction of the rotational axis 9. In the blade 11, a pair of right-left divided blade plates 13 and 12 are arranged in a plane in a substantially V shape along the longitudinal direction of the arm 15. One side becoming the X side in one rotational direction of the arm 15 when setting the rotational axis 9 in the divided blade plates 13 and 12 as the rotational center, is mutually rotatably connected, and the opposite side is mutually openably-closably arranged. A first coil spring 21 and a second coil spring 22 are interposed between the divided blade plates 13 and 12 side and the arm 15 side. Stable power generation can be provided by adjusting a rotating speed with a simple structure by opening-closing the pair of right-left first and second divided blade plates 13 and 12 in response to the wind direction Z and wind pressure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
