Buoyancy power generator

Description

Power generation device using buoyancy

[0001] The present invention relates to a power generation device using buoyancy, and more specifically, to a buoyancy power generator that utilizes the difference in volume of an air bladder according to the direction of buoyancy and the direction of tension of a floating body (air bladder) underwater.

[0002] Tidal power generation is generally divided into two types: one that utilizes the difference in water level due to the ebb and flow of the tide, and one that utilizes the horizontal flow force of the tide. Among these, the method that utilizes the difference in water level due to the ebb and flow of the tide blocks an estuary or bay with a breakwater and generates power by utilizing the difference in water level between the inside and outside of the breakwater caused by the tide. This generates electricity by rotating a water turbine generator while causing seawater to fall from the side with a higher water level to the side with a lower water level.

[0003] Tidal power generation has drawbacks, such as relatively low efficiency and high construction and maintenance costs. However, it offers significant advantages, such as the enormous amount of energy available and its non-polluting nature. Therefore, countries with favorable geographic conditions, including Korea, are actively pursuing its use as a future alternative energy source. However, tidal power systems suffer from low power generation efficiency in areas with small tidal ranges and the high costs of facility installation and maintenance.

[0004] Meanwhile, a plan to generate power by installing water turbines in waterways is also being implemented, but water turbines in waterways cannot generate power during the dry season, and there is a risk of damage to the power generation facilities when floods occur.

[0005] In addition, devices that generate power using underwater turbines have the problem that divers must enter the water to perform dangerous work and that maintenance costs increase when the turbines are damaged or broken due to floods, typhoons, etc.

[0006] Prior art documents in the technical field to which the present invention belongs include Korean Patent Publication No. 10-2023-0037089, etc.

[0007] The present invention was created to solve the above problems, and its purpose is to obtain power without using other carbon energy by utilizing the difference in buoyancy of a floating body underwater.

[0008] In order to achieve the above object, a power generation device through buoyancy according to a preferred embodiment of the present invention is characterized in that the air volume of the left side of the buoyancy part acts toward the rotating frame and is determined by the water pressure and the pulling tension of the left and right low-pressure pistons according to the depth of the buoyancy part, the air volume of the left buoyancy part is the water pressure + the tension of the left and right low-pressure pistons, the air volume of the right side of the buoyancy part is determined by the water pressure according to the depth of the buoyancy part when the pulling tension of the left and right low-pressure pistons is offset by the buoyancy of the buoyancy part, and the air volume of the right buoyancy part is characterized in that the tension of the left and right pistons - the buoyancy of the buoyancy part + the water pressure.

[0009] In addition, the tension of the left and right low-pressure pistons applied to the buoyancy part is characterized in that it becomes equal to or smaller depending on the buoyancy according to the air volume of the buoyancy part.

[0010] In addition, the density of the water inlet and outlet passages of the upper plate of the buoyancy unit, the fixed plate fixed to the upper plate, and the anti-separation tank is characterized by being equal to or less than the density of water.

[0011] According to the power generation device using buoyancy according to the present invention, the effect of generating electricity can be obtained through the difference in volume of the air pocket according to the direction of the buoyancy portion and the direction of tension.
