A wind generator with a wind blade rotating cage for driving multiple generators is disclosed. Sixteen wind blades (8) manufactured by a stretch extrusion process are mounted on the periphery of the wind blade rotating cage (5) suspended by magnetic force. Inner gears (3) are mounted on the inner edge of the wind blade rotating cage (5). Two of an upper and a lower generator cabins (12) are provided on an upright post (1) and eight generators with an electromagnetic clutch are provided inside each generator cabin (12). A gear (2) engaged with the inner gear (3) on the wind blade rotating cage (5) is mounted on a generator shaft (26) extending outside the generator cabin (12). The wind blade (8) is outward convex and inward concave, 1.5 meters wide and 40 meters high. The wind blade (8) has a large wind receiving area and is mounted on the periphery, so the torque produced is large. Inner gears (3) drive the gears (2) of the generator to rotate and the loss of kinetic energy is small. A lightning rod is also provided on the wind generator. The wind generator has a high wind energy utilization ratio, a simple structure and a low operation cost. |
