PURPOSE: A foldable variable width type vertical axis wind power generator is provided to prevent the degradation of portability of a transportation unit and to easily control the torque of the axis of a generator by controlling the distance between a blade and a rotary axis. CONSTITUTION: A foldable variable width type vertical axis wind power generator comprises a vertical axis rotation blade(10) and a generator(20). The vertical axis rotation blade comprises a rotation axis(110), a lower part fixing ring(120), a connection part(130), a blade(140), and a fixing ring movement part(150). The rotation axis is axis-connected with the generator axis(210). The lower part fixing ring is equipped in the rotation axis and moves up and down along the rotation axis. The connection part comprises a first connection link(131) in which an upper side is axis-connected with the upper part of the rotation axis, and a second connection link(132) in which the lower side is axis-connected with the lower part fixing ring. The lower side of the first connection link is axis-connected to the inner periphery of the lower part in a blade, and the upper side of the second connection link is axis-connected to the upper periphery of the upper part. The fixing ring movement part moves the lower part fixing ring up and down. |
