In general, a buoyant body is a buoyant action so that it floats from the water to the surface, and is also called a buoy, a buoy, or a buoy.

These buoyancy bodies are being used to install various structures on the water.

In recent years, the solar power generation efficiency is high due to the low radiation heat of the water surface.

That is, a number of buoyancy bodies are floated on the water surface, and various mechanisms such as a frame for installing a solar power module thereon are installed.

Therefore, the buoyancy body must have a significant buoyancy in order to float the solar power plant on the water surface.

The conventional buoyancy body is largely composed of a foaming type in which a synthetic resin is foamed and an injection molding in which the inside is empty by injection molding.

Such a conventional buoyancy body is made of a synthetic resin material, so there is a problem in that it is a source of contamination of freshwater and seawater because harmful substances are generated when it comes into contact with or damaged by water.

On the other hand, in freshwater and seawater, green algae and red algae occur due to eutrophication, and the amount of dissolved oxygen in the water rapidly decreases, killing fish and aquatic organisms.

Therefore, nutrients such as phosphorus and nitrogen related to the propagation of green algae and red algae are removed in advance, or water fountain to remove the generated green algae and red algae, water circulation, aeration, loess and coagulant input, microorganism input, physical green algae and red algae A collection method is used.

However, the conventional prevention and removal of green algae and red algae was accomplished by mobilizing separate equipment and manpower, and the cost was also considerable.

When the air pump 50 is operated by receiving electricity generated from the photovoltaic device, the pumped air is supplied to the air supply pipe 60 and the induction injection pipe 91 .

The high-pressure air supplied to the air supply pipe 60 is supplied to the bubble generating pipe 71 of the bubble generating unit 70 , and then is discharged to the flow path 30 as microbubbles by the bubble generating nozzle 72 .

The microbubbles are discharged from the upper surface of the submerged sphere 20 , which is the bottom surface of the flow path 30 , and rise through the water passing through the flow path 30 .

The microbubbles discharged to the flow path 30 increase the amount of dissolved oxygen in the water passing through the flow path 30 , and activate aerobic microorganisms to remove green algae and red algae and prevent them in advance.

On the other hand, the water passing through the flow path 30 forms a vortex by the vortex forming plate 80, and the green algae and red algae are stirred by the vortex.

In addition, the microbubbles ejected by the vortex jet nozzle 101 can prevent the green algae and red algae from being stacked on the rear surface of the vortex forming plate 80 by the vortex.

The ultrasonic generator removes the green algae and the red algae by destroying the cells of the green algae and the red algae passing through the flow path 30 with ultrasonic waves. And, green algae and red algae are floated in close contact with the bottom surface of the buoyancy sphere 10, which is the upper layer of the flow path 30, by the microbubbles.

In addition, green algae and red algae passing around the positive electrode 121 and the negative electrode 122 of the electrolysis unit are removed by electric shock and electrolysis, or aggregated and floated by microbubbles.

On the other hand, the buoyancy ball 10, which is an embodiment of the present invention, is fixed to the bottom of a river, a hose, the sea, etc. so as not to be moved by the flow of wind or water on the water surface for installation of a floating photovoltaic device. Therefore, when there is a flow of water, water passes through the flow path 30 without external force, so that green algae and red algae can be removed or prevented through the above process.

However, when there is no water flow, the pumped air is supplied to the induction injection pipe 91 and high-pressure air is ejected from the front of the flow path 10 toward the flow path 30 through the induction injection nozzle 90, so that the surrounding of water can be made to flow into the flow path 30 by piggybacking on the air.

In addition, the high-pressure air ejected from the induction jet nozzle 90 may agitate the green algae and the red algae to increase the removal effect of the green algae and the red algae.
