Abstract

The present invention provides an apparatus for obtaining rotary power by rotating a shaft with an ascending force of a buoyant body, and comprises: a water tank; a waterwheel shaft in the water tank; a cylindrical chamber attached to the lower portion of the water tank; a rotator in the cylindrical chamber; a pipe for supplying a buoyant body to the cylindrical chamber; and a gear for connecting the waterwheel shaft to a shaft of the rotator. The buoyant body which descends to the lower portion of the water tank passes through the cylindrical chamber and enters the water tank via the rotator. On entering the water tank, the buoyant body ascends due to buoyancy and is caught by a waterwheel holder installed in the water tank. Then, the buoyant body ascends while pulling the holder upward. Due to the ascending force of the buoyant body, the waterwheel is rotated and then a power generator turbine, which is externally connected to the water tank, is rotated, thereby generating electricity.

Description

Power generation system using buoyancy

The present invention relates to a system and apparatus for generating electricity by turning a turbine using buoyancy.

In order to generate electricity, the generator turbine must be turned and energy must be applied to turn the turbine. The currently used generators are classified into thermal power generation, hydro power generation, nuclear power generation, wind power generation, tidal power generation, etc., depending on what energy source is for turning the power generation turbine. Among them, the thermal, hydro, and nuclear power generation methods use the steam pressure generated by heating the water to turn the power generation turbine, and the wind and tidal power generation methods use the natural energy to turn the power generation turbine without heating the water.

The present invention relates to a power generation system and an apparatus, and taking the form of obtaining electricity by turning a turbine is the same as a conventional generator, but uses buoyancy as an energy source to turn the turbine.

Each of the existing power generation methods listed above has disadvantages.

Thermal power plants that use fossil fuels, such as coal or oil, cause serious air pollution and will eventually run out of fossil energy.

In order to generate hydroelectric power, dams have to be built at a high cost and cause disruption of the ecosystem, and the topographical location of dams is limited.

In a wind power plant, when the wind is weak, power production is plunged, and there is a problem in constant power productivity, which requires stopping electricity generation even if the wind is too strong like a typhoon.

Solar power generation, which is attracting attention as an eco-friendly power generation, also has irregular power generation capacity according to seasons and climates, and when the panel reaches its end of life, another environmental problem occurs when discarded.

Nuclear power generation with high efficiency is well known for its safety and risks due to radioactive hazards of waste materials.

It is everyone's desire to minimize the energy resources consumed in the process of generating the electricity required for humanity and to produce it in a way that does not cause environmental pollution, but these technologies have not been developed yet.

The present invention uses the buoyancy of water as an energy source to turn the turbine. If hydropower uses the potential energy generated when water descends from the top to the bottom, this buoyancy generator causes the turbine to rotate using the buoyancy rising from bottom to top.

The difference from hydroelectric power generation is that only a certain amount of water must be flowed into a water tank made of a suitable size so that a buoyant body can rise around the water source, without the need for dam construction to store a large amount of water.

This buoyancy generator has a structure in which a small amount of water flows out in the process of raising the buoyancy body, and the spilled water can be sent back to the lower part of the water source through the waterway.

The force that can be produced by the buoyancy is proportional to the size of the buoyant body. As the buoyancy body size increases, the force increases exponentially, resulting in the same or more rotational force compared to the water pressure of a hydroelectric power station or the steam pressure of a thermal power plant. It is possible.

Research on power generation without fossil fuels is being conducted all over the world, but each has its own shortcomings, so there is no clear alternative to replace the existing power generation method.

Power generation using buoyancy uses water in the river as a water source, so it can always generate power regardless of weather or season. And the water that has been developed is returned to the water source, so it does not deplete water resources.

It is an eco-friendly power generation that does not emit pollutants at all during the power generation process, and enables sufficiently large-capacity power generation depending on the size of the buoyant body.

The present invention is an invention that can generate a huge ripple effect that can produce clean electric energy by replacing the existing power generation method.

Whether or not electrical energy can be generated when produced according to the contents of the present invention was proved through a prototype.

Two shafts are engaged with gears from the outside of the water tank so that both shafts are constantly rotating, so that when one buoyant body enters, one holder is always in 1: 1 correspondence to turn into an empty holder or two buoyant bodies hang on one holder Do not turn. This ensures that constant buoyancy is always produced and stable development.

In the present invention, there is a water tank when viewed from the outside, and a cylindrical chamber is attached to the lower part, and the water tank and the cylindrical chamber each have a rotating shaft, and the two rotating shafts are connected by a gear or a chain.

On the side surface, a recovery path for transferring the buoyant body from the top of the water tank to the bottom of the cylindrical chamber is installed.

There is a spinning watermill in the water tank, and the surface of the watermill has a holder protruding so that a buoyant body rising from the bottom is caught.

The principle of operation is to enter the ball-shaped buoyancy body into the lower part of the water tank through the cylindrical chamber. The buoyant body that entered the inside of the water tank rises to the upper part by the buoyancy and is caught by the holder of the watermill, and the watermill rotates the turbine while rotating by the buoyancy. The buoyant body that has been raised in the water tank is gathered to the recovery path, descends downward by gravity, and then rotates the turbine while repeating the endless circulation entering the water tank through the cylindrical chamber, and electricity is generated in this process.

If you explain each structure in detail,

The water tank is a space where the buoyant body enters and rises from the bottom, and a waterwheel type rotating body is installed inside the water tank, and a wing-shaped holder is protruded on the outside of the watermill to catch the buoyant body.

There is a cylindrical chamber at the bottom of the water tank, and a rotating rotor therein.

The cylindrical chamber has two holes on the side and the top, and the size of the hole is slightly larger than the diameter of the buoyant body.

There is a rotor inside the cylindrical chamber. On the surface of the rotor, deep grooves capable of holding and turning the buoyant body are dug at regular intervals.

The pipe that supplies the buoyant body extends from the top of the water tank to the cylindrical chamber at the bottom, and the buoyant body, which has a much lower specific gravity than water, is filled with a vertical array.

The operation of the power generation system begins with the buoyant body at the bottom being pushed by the gravity pushed by the other buoyant bodies stacked on the top and passes through the side hole of the cylindrical chamber to enter the groove of the rotor.

When the rotor holding the buoyancy body rotates at a certain angle, the buoyancy body is located at the bottom of the water tank. At this time, the water in the water tank is pushed into the rotor in an instant and filled up, and the buoyant body rises due to the water pressure and enters the water tank. The buoyant body that enters the water tank rises and is caught by the holder of the watermill and pushes the holder upward. The shaft of the watermill rotates as the holder moves up. The rotational force generated by the waterwheel shaft produces electricity by turning the turbine of a generator connected to the outside of the water tank through a chain and gears.

The rotor has been designed and designed to have very little energy consumed during rotation.

The first is designed so that the outer diameter of the rotor is smaller than the inner diameter of the circular chamber so that there is no friction with the outer circular chamber, but the leakage is minimized because it is in close contact.

The second is designed to keep going with its own torque.

After the rotor enters the buoyant body into the water tank, it crosses the center line while the groove is full of water. In this case, it becomes heavier than the opposite side of the center line, descends by gravity, and has a rotational force by descending until water is emptied from the bottom.

Although the rotor has its own rotational force, the reason why the waterwheel shaft and the rotor are connected by gears is to match the rotational speed of the watermill and the rotational speed of the rotor. That is, when the rotational speed of the two axes is always constant, when one buoyant body enters, one holder always corresponds 1: 1, so that there is no turning or emptying of two buoyant bodies in one holder. This causes a constant rotational speed due to a constant buoyancy, which enables the development of a constant size.

When the watermill rotates and rotates the lower rotor, the buoyant body continuously enters from the lower part of the water tank, and the buoyant body is continuously caught in the holder. Due to the increase in the number of holders that are still below the water surface and have a floating force, the lift force due to buoyancy is doubled and the rotation force becomes larger.

Increasing the size of the watermill increases the number of holders submerged in water, resulting in greater torque.

After the ascent, the buoyant body separated from the holder rises above the water surface and is subsequently pushed by the buoyant body and flows toward the recovery pipe.

The buoyant body introduced into the recovery pipe is again descended by gravity and ready to enter the lower cylindrical chamber again, thereby rotating the watermill shaft while infinite circulation.

A buoyancy generator having an operating structure that acquires an upward force by entering a buoyancy body through a chamber at the bottom of a water tank can be implemented in a slightly modified form described below, but the principle of operation is the same.

The waterwheel shaft installed inside the water tank can also be manufactured with a sprocket structure at the upper and lower parts connected by an attachment chain (chain to which attachments can be attached). On the attachment chain, a holder for holding the buoyancy body is attached at regular intervals. The buoyancy body starting from the lower part of the water tank is caught by this holder, and when the holder is raised, the sprocket shaft rotates to obtain rotational energy. This type of structure can be manufactured with a narrower width than a watermill type water tank, thereby increasing the utilization of space. In addition, more holders can be mounted than the waterwheel type, which has the advantage of increasing the combined force of buoyancy.

As another form using the same mechanism, the cylindrical chamber and the rotor under the water tank can also be manufactured in the form of a tetrahedral chamber and a slide.

The tetrahedral chamber has a door on the side and an upper side to which a buoyant body can enter and exit, and a slide plate to open and close the door is installed.

The principle of operation is as follows.

When the slide plate on the side is opened while the slide plate on the top side is closed, the buoyant body that is waiting enters the chamber by gravity, and then the side window is closed by the slide plate. At this time, the slide plate on the upper side, which prevented water from spilling from the upper water tank, opens, and the water in the water tank flows in. The chamber is filled with water, and the buoyancy body naturally rises upward by buoyancy and enters the inside of the water tank. And the upper slide plate is closed again, and in the process of opening the slide plate on the side, the water in the chamber flows out and the chamber is emptied, ready to accept the next buoyant body. The operation mechanism is the same as that of using a cylindrical chamber and a rotor. The cylindrical chamber requires a cylinder about 2.2 times the diameter of the buoyant body, but this tetrahedral chamber can be produced if it is 1.2 times the diameter of the buoyant body. It has a more advantageous advantage in space utilization and manufacturing.

As shown in FIG. 17, a buoyant power plant is installed around the flowing river water, and the water is drawn into the river to generate power.

Since thermal power plants need cooling water to cool the steam after turning the turbine, they are built a lot on the beach and require a lot of construction cost to prevent corrosion from salt water.

Hydroelectric power plants have a lot of topographical limitations, and large-scale civil works are required to construct dams, and environmental changes are brought about.

However, the buoyancy power plant can be constructed with only a small tributary river rather than a large river, so there are few topographical limitations, and it can be said that it is superior in economic efficiency because it does not require large-scale construction.
