Abstract

The present invention relates to a movable rotor blade structure for vertical wind-powered electricity generation. The invention comprises: a blade frame which is provided fixedly on a vertical rotational shaft for wind-powered electricity generation, and on the top and bottom edges of which are respectively formed horizontal rails; a movable blade which is half the length of the blade frame, and which is provided on the blade frame in such a way as to be able to move sliding along the rails; and a blade-operation controller for controlling the operation in such a way that, with every 180 degrees of rotation when the blade frame is rotating due to the force of the wind, the movable blade is moved from the blade frame on one side which is rotating backward against the wind centred on the vertical rotational shaft, and towards the blade frame on the other side which is rotating forward in the opposite direction. The invention has the advantageous effect that it can increase the mechanical conversion efficiency for wind power since blades experiencing a force from the wind are only ever positioned on the side rotating forward with the wind centred on the vertical rotational shaft, and the force of resistance due to backward rotation of the blade is minimised.
