Abstract
The utility model relates to the field of generators, in particular to a wind-driven generator with a wind gathering cover. The wind-driven generator with the wind gathering cover comprises a tower, a cabin, a stator, a rotor and a plurality of vanes. The cabin is mounted on the tower through an articulated shaft. The rotor which is covered by the stator is hinged inside the cabin. The stator is fixedly connected with the inner wall of the cabin. A gap is reserved between the stator and the rotor which are coaxially disposed. A rotary shaft is fixedly mounted at the axis of the rotor. The vanes are circumferentially, uniformly and fixedly mounted on the rotary shaft. The wind gathering cover is fixedly mounted outside the vanes. Due to the fact the horn-mouth-shaped wind gathering cover covers outside the vanes of the wind-driven generator, windward area of the vanes is increased by the wind gathering cover, and power generating efficiency of the wind-driven generator is improved.
