Wind power generation device

A wind power generation device, comprising:

• a base;
• a wind gathering tower, installed on the base, structured as a radial frame, internally provided with a Cavity running through up and down, the cavity wall being circumferentially provided with a plurality of wind gathering doors which can only be opened inwards;
• a vertical power generator, disposed at the bottom in the cavity of the wind gathering tower and installed at the base, a driving shaft thereof axially extending upward and outside;
• a vertical spiral turbine, installed above the vertical power generator, comprising upper turbine blades, a lower inertia wheel and a crankshaft connecting the turbine blades and the inertia wheel, the lower end of the crankshaft penetrating through the inertia wheel and being in drive connection with the upward extending driving shaft of the vertical power generator, an air outlet of the vertical spiral turbine being upward;
• a turbine air-intake barrel, installed on the base at the bottom in the cavity of the wind gathering tower, embracing the vertical power generator and the vertical spiral turbine inside, the middle part thereof being provided with an air inlet that is connected with the turbine blades, and the lower part being provided with a crosswise support plate between the vertical power generator and the inertia wheel of the vertical spiral turbine;
• a horn-shaped wind guiding barrel, disposed in the central position in the cavity of the wind gathering tower, an upper opening of the horn-shaped wind guiding barrel being closely connected with an upper opening of the wind gathering tower, a lower opening being integrally connected with the turbine air-intake barrel, a wind gathering channel being formed between the integrated piece of the horn-shaped wind guiding barrel and the turbine air-intake barrel and the wind gathering tower, the lower part of the wind gathering channel being connected with the air inlet of the turbine air-intake barrel;
• and,
• umbrella-shaped wind pumping barrel, connected above the horn-shaped wind guiding barrel, comprising a frame structure integrally connected with the wind gathering tower and a cone body which is disposed in the frame structure and has at least one hollow layer, the conical surface of the cone body being provided with a plurality of wind pumping doors that can only be opened outward, and the bottom edge of the cone body being provided or not provided with suction openings or exhaust outlets in the vertical direction.
