CYLINDRICAL WINDMILL FOR WIND POWER GENERATION

摘要

The present invention relates to a cylindrical windmill for wind power generation and is directed to provide a cylindrical windmill for use in a vertical axis wind power generation system, which is designed for more efficient use of the wind power energy by expanding a wind power-receiving area while minimizing the rotational resistance by wings. To this end, the cylindrical windmill for wind power generation according to the present invention comprises: a support frame formed in a cylindrical shape around a rotational shaft; a plurality of wing fixtures protruded from the support frame; a plurality of wing fixing plates, each of which is fixed to the corresponding wing fixture and has elastic properties; and a plurality of wings, each of which is composed of an operating range installed in such a manner that the middle portion between the center and the tip of a wing is fixed to one side of the wing fixing plate to open or close a space that is formed between the wing fixture and the wing fixing plate, and an auxiliary operating range adapted to protrude outside the wing fixture when the space is opened by the operating range.
