Wind energy electricity generator for low wind velocity

In the wind energy electricity generator for low wind velocity, the device is formed in a long cylindrical pole and has the central shaft that generates the rotational power by being supported in a rotatable form;

• in the cover plate coupled with the above central shaft, the axle coupling part having the prolate groove is formed on the center, and in order to increase the moment of rotation, the overlapping regions is formed based on the central shaft and placed and fixed in the same rotational direction and the overlap ratio of the above overlapping regions is formed by subtracting the diameter of the shaft of the central axis from the X axis spacing overlapped between the semicircles and dividing the value with the diameter of the semicircle when the central axis of the center axle is configured with a shaft and the drag-type blade in the shape of semicircular ring formed by dividing the X axis spacing overlapped between the semicircles with the diameter (d) of the semicircle when the central axis of the center axle is configured with the drag-type blade without a shaft;
• the airfoil-type blade connected to the outer peripheral surface of the above drag-type blade by the support fixture that maximizes the tip speed ratio by rotating integrally with the drag-type blade;
• the generation module located on the extension line of the central shaft and produces electricity by receiving the rotational driving force of the central shaft;
• while the above drag-type blades are formed in multi-stages of the block units to the longitudinal direction and the above airfoil-type blade are formed in a vertical standing positions parallel to the above central shaft.
