<p>A wind-collecting device for a wind generator including a radial wind-collecting means,which is located around the outer periphery of the wind inlet of the blades of the wind generator.Many radial wind-collecting passages communicated with the wind inlet of the wind generator are formde between the blades of the radial wind-collecting means.The flowing cross section of the radial wind-collecting passage adjacent to the center of the wind generator is smaller than the flowing cross section situated at the outer side part of the radial wind-collecting passage.The wind-collecting means provides high quality and virtual wind energy for the wind generator,improves energy sources structure and environment,and can be used broadly.</p>
