Buoyancy power generation structure

The invention discloses a buoyancy power generation structure. The structure comprises: a reservoir, a chain wheel assembly, a plurality of buoyancy members, a driving machine and a speed reducer, thechain wheel assembly is provided with a plurality of buoyancy members in the water storage tank; the driving machine drives the inflation pipe to be inserted into the buoyancy members which are positioned at the lowest part and has a downward opening part to inflate; Therefore, all the buoyancy members with the downward opening parts are inflated with air, so that the chain wheel assembly can bedriven to continuously rotate through the buoyancy of the buoyancy members and the stable rotating speed can be controlled through the cooperation with the speed reducer; and when the buoyancy membersmove to the uppermost part of the water storage tank, the buoyancy members are exposed out of the water surface and exhaust air, so that the circulating action of continuous air inflation and exhaustis completed, and the gear
