High-performance wind turbine generator that can be driven in horizontal/vertical axis directions with the use of 3D active intelligent turbine blades

摘要

Provided is a 3D active intelligent-type high-performance wind turbine generator. The 3D active intelligent-type high-performance wind turbine generator may be driven in horizontal/vertical axis directions. This novel wind turbine generator includes blades for driving a generator shaft of which cross sections are arranged symmetrically to increase the efficiency of the wind turbine generator and a cylindrical type cam and cam follower for controlling the angle of each blade in every direction to an optimum condition, so as to guide a working fluid having kinetic energy to be introduced at right angles to the direction of the cross section of each blade, thereby maximizing the driving force of the blades. Thus, the wind turbine generator may operate satisfactorily even at a low initial start-up wind speed and may be driven in any horizontal/vertical axis directions.

1. A vertical axle wind power generator, in which a positive torque is generated on a blade in a forward wind area, and a pitch angle is adjusted so that a drag of the blade is minimized in an adverse wind area, using a 3-dimensional (3D) active intelligent type turbine blade, the vertical axle wind power generator comprising:
one cylindrical cam of a first cylindrical cam having a flat traveling guide surface and a second cylindrical cam having a traveling guide surface in which a rounded groove is defined; and one cam follower of a first cam follower fixed to an arm fixed to the blade in a spherical roller shape, a second cam follower operated in the spherical roller shape with respect to a spline axle disposed on the arm fixed to the blade, and a third cam follower fixed to the arm movably hinge-coupled to the blade in the spherical roller shape, wherein since a roller of one of the cam followers travels along a traveling guide surface of one of the cylindrical cams in a state where the roller is closely attached to the traveling guide surface, when the roller of one of the cam followers travels along the traveling guide surface of one of the cylindrical cams, the blade performs a pitch movement a pitch motion for changing a rotation angle with respect to an axle of a length direction thereof, wherein, when the first cam follower travels along the traveling guide surface of the second cylindrical cam, the first cam follower is disposed so that an extension line of a central axle of the first cam follower passes through a center point of a drive axle always, when the second cam follower travels along the traveling guide surface of the second cylindrical cam, the second cam follower is connected operable with respect to the spline axle of the arm to receive the spline axle corresponding to a moved distance of the second cam follower with respect to the spline axle, or when the third cam follower travels along the traveling guide surface of the second cylindrical cam, the arm connected to the third cam follower is hinge-coupled to the axle in the length direction of the blade to receive the central axle of the arm corresponding to a changed angle of the central axle of the arm with respect to the axle of the length direction of the blade, wherein one of the first and second cylindrical cams and one of the first to third cam followers are respectively received into an upper control system housing and a lower control system housing, and in the upper and lower control system housings, a central portion of a side portion through which the blade axle protrudes has the lowest diameter, and each of upper and lower ends of the side portion has the lowest diameter.
