<p>A vortex wind wheel for a wind generator includes an axial sleeve (2), the outer edge of the axial sleeve (2) connects with many wind blades (1) fixedly, the wind blades (1) are twisted into U shape from blade tips (11) to blade roots (12) gradually, the wind blades (1) are contracted from the blade roots (12) to the blade tips (11), and they are formed into a sharp angle at the blade tips (11), the wind blade (1) is divided into the front part (14) and the rear part (13) by a connection line from the blade tip (11) to the midpoint of the blade root (12), the projection area of the rear part (13) is bigger than the projection area of the front part (14). The vortex wind wheel can use horizontal air flow and rising air flow, and the resistance against wind is small.</p> |
