Wind power generation device

The utility model belongs to the technical field of green energy, and discloses a wind power generation device which comprises a base plate, a sleeve arranged on the base plate and a rotating shaft movably penetrating through the sleeve, one end of the rotating shaft is connected with an impeller, the other end of the rotating shaft is connected with a power transmission unit, and the power transmission unit is connected with a generator. And a wide-mouth air gathering ring is arranged at the periphery of the impeller. The wind power generation device provided by the utility model is horizontally arranged and occupies a small area; the wide-mouth wind gathering ring can gather the draught fan to the impeller, the specially-made fan blades distributed in a cone shape can maximize the contact area between wind and the fan blades, the power transmission unit can amplify the rotating speed of the rotating shaft and increase the input rotating speed of the generator, and therefore motion wind energy is converted i
