Buoyancy power generation device

Abstract

A buoyancy power generation device includes a support frame installed inside a water storage tank. A first sprocket is mounted at the bottom of the support frame, and a second sprocket is mounted at the top of the support frame. A float chain is installed between the first and second sprockets to drive them synchronously. Several floats are mounted on the float chain. A one-way valve is installed at the bottom of each float to open towards its interior. A generator is connected to either the first or second sprocket. An air inlet is installed at the bottom of the support frame and connected to an air pumping device. The air outlet of the air inlet is located on the rising side of the float. The air pumping device discharges air from the air inlet, forcing the water inside the float to be expelled from the float, generating upward buoyancy. This buoyancy, through the float chain, drives the first and second sprockets and the generator to move, thereby achieving power generation.
