Description

{ Floating body for offshore structure installation }

The present invention relates to a floating body for installing offshore structures, and more particularly, to a floating body made of EVA (ethylene-vinyl acetate copolymer), which is composed of a lower buoyancy part and an upper buoyancy part provided with a support plate capable of binding the structure. By forming the buoyancy part of the EPP (Expanded Polypropylene) or EPS (Expanded polystyrene) material inside the floating body, the floating body is soft and has excellent elasticity as well as an external impact by the buoyancy part formed inside the buoyant body. It is possible to improve the buoyancy rate while preventing it from being easily damaged in the The fluid can be produced semi-automatically to improve workability and productivity, and a sealing means is formed in the portion where the lower buoyancy part and the upper buoyancy part are combined to prevent seawater from flowing into the lower buoyancy part to the maximum. It relates to a floating body for installation of an offshore structure.

In general, a floating body is floating in a state partially exposed to the sea or lake.

In this way, because part of the floating body is exposed to the sea or lake, etc., in the coastal sea, a net is hung on a floating body for cage farming, or a boat can be anchored using a floating body floating in the sea or lake.

On the other hand, electricity is produced using a power generation device, which includes a thermal power generation device that generates power using fossil fuels, a wind power generation device that generates power using wind, and a nuclear power generation device that generates power using nuclear fission. are distinguished by

Since the thermal power generation device generates electricity using fossil fuels, various pollutants are generated during the combustion of fossil fuels, and the environment is polluted due to the pollutants.

In addition, the wind power generator uses wind to produce electricity, but the conventional wind power generator has a problem in that the environment is damaged because it is necessary to mow the mountain or remove the tree in order to install it in a mountain or valley where there is a lot of wind. did it

And, since the nuclear power generation device generates power using nuclear fission, there is a problem in that the radioactivity is exposed to the outside as it is when the nuclear power generation device malfunctions or is damaged.

In order to solve this problem, a solar thermal power generation device that generates electricity using solar heat was invented.

However, since the conventional solar power generation device is installed on the ground, there is a problem in that the solar installation cost is increased.

In order to solve this problem, a solar power generator is installed on a floating body floating in the sea or lake.

In order to install a solar power generator in the sea or lake, a plurality of floating bodies are connected to a frame, and a photovoltaic module is installed in the frame.

However, the problem with the conventional floating body on which the solar and power generation module is installed is that the frame is coupled to the floating body that is made of Styrofoam and has a circular cross section, so the strength of the floating body to which the frame is coupled is lowered. There was a problem that the floating body was easily damaged by the pressure.

In addition, since the frame is installed on the floating body having a circular cross section, there is a problem in that the damaged floating body must be replaced with a whole when the floating body is damaged.

And since the frame, which is a structure, is coupled to the floating body having a circular cross section, there is a problem in that the coupling of the frame, which is the structure, to the floating body is not easy.
