Turbine device by two water tanks with different water potential energy

摘要

The present invention relates to a buoyance turbine which utilizes potential energy of flowing water of a river or stream, and which generates electricity using water buoyancy by installing upper and lower water tanks underground to overcome water pressure. More specifically, as multiple buoyancy bodies, which are formed into belts, rise up in the water in the water tank, Shoulder bar of the buoyancy bodies starts operation of rotating upper and lower rotational shafts starts through gears. As a result, the buoyancy bodies move outside the water tanks during the operation that the belt-form buoyancy bodies move down to the lower rotational shaft, and the belt-form buoyancy bodies and buoyancy body wing plates rotate the upper and lower rotational shafts. Especially, since a height difference between the water tanks storing the water is configured not to be big, the present invention relates to a generally used power generation method using buoyancy energy of the water, which is used to effectively generate electricity around rivers and streams.
