Abstract

PROBLEM TO BE SOLVED: To provide an energy-saving and pollution-free power generation apparatus that can easily generate power in a water tank, tank, sea, lake, river or the like if there is a certain depth of water.
SOLUTION: In an aquarium, an expandable / shrinkable container installed so as to be able to rotate and circulate is supplied with compressed air at the start of ascent, and the container is lifted to generate buoyancy caused by water pressure as it rises. Thus, the power source uses the power source to generate power in conjunction with the power generation conversion device.

Description

The present invention relates to an energy-saving and pollution-free power generation apparatus using gravity, water pressure, and underwater buoyancy that exist in nature.
Specifically, this is a power generator that supplies compressed air at the start of ascent to an expandable / contractable container installed in a water tank so that it can be rotated and circulated in a water tank, and uses buoyancy generated by water pressure as a power source.

Conventional power generators include thermal power generators that burn fossil fuels, hydroelectric generators that drop water from high altitudes, nuclear power generators that fission uranium fuel, tidal power generators that utilize tidal differences, A wave power generation device that uses vertical motion, a solar power generation device that uses sunlight, a wind power generation device that uses wind, and the like are known.
However, each of the above power generation devices has been pointed out with problems such as location conditions, construction costs, environmental conservation, safety, stable supply, power generation capacity, power transmission facilities, power generation costs, and the like.

In particular, conventional hydroelectric generators require large reservoirs and dam lakes at high altitudes and mountainous areas, leading to high construction costs, and environmental destruction due to construction is also a major social problem. .
In addition, the amount of water required for stable power generation is highly dependent on natural phenomena and cannot be installed in dry, desert, and urban areas.

In order to solve these problems, an apparatus is also disclosed in which a large number of floating bodies are attached to an ascending / descending rotary body using air pressure and the air is blown to cause rotation by raising the floating body in the water tank. (For example, JP-A-2001-207945).
However, since the floating body remains open in water, the generated force is reduced and the transmission efficiency is low and unstable.

The conventional hydroelectric generator has the above-described problems.
The purpose of the present invention is to solve the problems of the location conditions, environmental conservation, construction costs, and power generation costs of hydroelectric generators in particular, and it does not require large reservoirs or dam lakes. We intend to provide an energy-saving and pollution-free power generation device that can generate electricity if there is a water tank.

In order to solve the above-mentioned problem, the present invention supplies compressed air to an expandable / contractable container 2 installed in a water tank 1 so as to be capable of rotating and circulating in a water tank via an air compressor 3. The power generator is configured to drive a generator directly or indirectly using buoyancy generated by water pressure as it rises as a power source.
Furthermore, in order to efficiently generate power, a method of supplying compressed air through a perforated suction plate was also adopted.

Conventional power generators have a negative impact on the global environment due to the destruction of the natural environment by dams, global warming due to depletion and combustion of fossil fuel resources, nuclear safety, and spent nuclear fuel treatment. The power generation using this can solve these problems and obtain permanent power.
In addition, since the power generator of the present invention has a simple structure and can generate electricity if there is a certain amount of water depth, there are no restrictions on the installation location, and it can be installed in tanks, seas, lakes, rivers, ponds, etc. It is also possible.
Furthermore, since the scale of the power generator of the present invention is not limited, the capacity and number of expansion / contraction containers can be adjusted according to the amount of power required, and can be installed and expanded in factories, facilities, and homes. It is.

A power generation device of the present invention includes a water tank having a certain depth, a support stand standing vertically in the water tank, and a plurality of expandable and contractible containers installed on the support base so as to be able to rotate and circulate at regular intervals. It has means such as an air compressor device for supplying compressed air to the expandable / shrinkable container and a power generation conversion device for converting the generated power source into electric energy.
Further, in order to efficiently generate power, it is effective to supply the compressed air to the expandable / contractable container through a suction plate having a perforated structure.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In a water tank 1 having a certain depth, a plurality of inflatable / contractable containers 4 are installed on a support stand 3 standing vertically in the water tank 1 so as to be able to rotate and circulate at equal intervals. Compressed air from the air compressor 4 is supplied from the compressed air supply port 6 to the retractable container at the bottom of the rising start, and the expandable / shrinkable container is raised in an expanded state, and at the top of the rising end slightly above the water surface 2, Electric power is generated through a power generation conversion device (not shown) using the buoyancy generated by the water pressure as the power increases.
After the end of the rise, the inflatable / shrinkable container circulates while descending in the contracted state, reaches the lowest start of the rise, and repeats the same operation.

In the embodiment, a water tank is used. However, as long as the water tank has a certain depth, it can be installed in a tank or the sea, a lake, a river, a pond or the like other than the water tank.
In the case of water tanks, tanks, etc., there is no problem even if the method is carried out by embedding part or all of them in the ground.

Next, the bottom shape of the expandable / shrinkable container is preferably substantially circular, but there is no problem even if it is a triangle, a quadrangle, or another polygon.
In addition, any material can be used as the material of the expandable / shrinkable portion of the expandable / shrinkable container as long as it is a lightweight, high-strength, expandable / shrinkable material such as silicone rubber, fluorine rubber, polypropylene fiber, polyamide fiber, and polyimide fiber. .
The expansion form of the inflatable / shrinkable container may be a bag shape, but a structure that is gradually narrowed toward the upper end is more effective.

  Furthermore, when the compressed air is supplied to the expandable / shrinkable container via the suction plate 7 having a perforated structure, mixing of water, that is, liquid is prevented, and only supply of air, that is, gas is obtained, and gas is less than that of the liquid. Since the pressure can be increased by the momentum, it is more effective.

  It is explanatory drawing which shows one Example of this invention.   It is explanatory drawing which shows one Example of the inflatable / shrinkable container of this invention.   It is a plane explanatory view showing one example of a perforated compressed air suction plate of the present invention.
