Document Type and Number:
WIPO Patent Application WO/2014/175613
Kind Code:
A1
Abstract:
The present invention relates to a wind power generator using a vertical shaft scheme, the wind power generator comprising: a generator (110), a rotating shaft (120) vertically disposed to transfer a rotational force to the generator (110); a rotor plate (130) fixed vertically with respect to the rotating shaft (120); a plurality of blades (140) vertically buried in the rotor plate (130) on the same radius with respect to the rotating shaft (120) and arranged to be symmetric to the rotating shaft (120) and to spirally rotate about the rotating shaft (120); and a plurality of weight members (150) provided to be rotatably symmetric to the rotor plate (130) so as to be movable in a radial direction according to the rotating speed of the rotor plate (130), wherein each blade (140) has a connection surface (141) facing the rotating shaft (120), and a first wind pressure surface (142) and a second wind pressure surface (143) bent and connected at both sides of the connection surface (141), the connection surface (141), the first wind pressure surface (142), and the second wind pressure surface (143) corresponding to a wing-shaped structure in which an angle between each blade (140) and a tangential line of the installation radius R of the rotor plate (130) is constant. Further, the first wind pressure surface (142) and the second wind pressure surface (143) have different curvatures, and are bent in the same direction, thereby improving a turbine efficiency using a lift force and a drag force, and improving a constant speed operation property to stably generate electric power. A plurality of grooves (201) are provided on the first wind pressure surface (142), thereby delaying separation of an air layer so as to perform smooth rotation, and protrusions (410) and (420) for maximally utilizing wind introduced to the second wind pressure surface (143) at various angles are provided, thereby maximally utilizing a kinetic energy of wind
