PURPOSE: A vertical shaft wind turbine blade is provided to improve efficiency and to minimize backward resistance by utilizing the wind blowing to the reward direction of a vertical shaft wind turbine. CONSTITUTION: A vertical shaft wind turbine blade comprises a blade(1), a blade front side(2), and an inner blade(3). Covers are combined on top and bottom of the blade, respectively. Four wings are mounted around a shaft(4) and constitute a vertical axis wind turbine. The curve of the blade is cycloid curve. The air flow, which is separated from the front side of the blade, moves in rotation direction along the curved line of blade. The wind, separated from the blade front side is branched to bidirectional moment from the blade front side.

Description

수직축 풍차의 날개{Vertical-axis windmill wings}Vertical-axis windmill wings}

본 발명은 수직축 원통형 풍차 회전역방향 날개의 저항을 최소화하기 위한 수직축 풍차의 역방향 회전날개에 관한 것이다.The present invention relates to a reverse rotary blade of the vertical axis windmill for minimizing the resistance of the vertical axis cylindrical windmill rotation reverse wing.

수직 축 원통형 풍차의 다양한 날개의 종류가 개발 되어 있으나 종래의 기술로는 수직축 풍차 날개의 회전역방향 저항을 최소화 할 수 있거나 역 방향 바람을 회전 방향으로 최대한 활용하는 본 발명에서 개시하는 날개의 구조로 구성되는 것이 없다.Various types of vanes have been developed in the vertical axis cylindrical windmill, but the conventional technology is composed of the structure of the blade disclosed in the present invention that can minimize the reverse rotational resistance of the vertical axis windmill blade or maximize the reverse wind in the rotational direction There is nothing to be done.

수직축 원통형풍차는 풍향에 영향을 받지 않고 풍속이 약한 바람에도 전기를 생산할 수 있는 장점은 있으나 수직축 원통형 풍차 지름의 절반에 해당하는 날개에는 저항을 받고 프로펠러 형 수평축 풍차 에 비해 지름이 커야하는 단점을 최소한 해결하기위한 것이다.The vertical cylindrical windmill has the advantage of producing electricity even when the wind speed is weak and not affected by the wind direction. Is to solve.

수직축 풍차의 역방향 바람을 회전 방향으로 활용하기 위하여 역방향 바람이 날개에 추돌함과 동시에 대부분의 바람이 회전 날개 방향으로 진입 되도록 하여 역방향 바람이 회전방향의 날개에 압력을 가하게 한다.In order to utilize the reverse wind of the vertical windmill in the direction of rotation, the reverse wind collides with the wing and most of the wind enters the direction of the rotating wing so that the reverse wind pressurizes the wing in the direction of rotation.

수직축 풍차의 역방향으로 향하여 부는 바람을 회전방향으로 대부분 활용하게 되므로 역방향 저항을 최소화 하므로 효율을 향상시키는 효과가 있다.Since most of the wind blowing in the reverse direction of the vertical axis windmill is utilized in the rotational direction, it minimizes the reverse resistance, thereby improving efficiency.
