Description

Float for marine culture

The present invention relates to a buoy for aquaculture, and more particularly, to a buoy for aquaculture capable of maintaining buoyancy even when externally damaged.

A buoyant, a buoyant or a buoyant body (hereinafter referred to as a 'buoy') that can support the aquaculture net for culturing seaweed or seafood by buoyancy has been mainly used for those formed of Styrofoam.

However, the buoy composed only of Styrofoam has a problem in that its durability is weak and easily ruptured even with a small impact, resulting in an extremely short lifespan. In addition, as the Styrofoam buoy is damaged, the particles falling from the buoy heavily contaminate the ocean and stick to the aquaculture, so washing may be added during the process of collecting the aquaculture, and there is also a problem in that the merchantability is reduced accordingly. The buoyancy formed of such styrofoam has a disadvantage in that peeling proceeds or buoyancy is gradually reduced due to the water-absorbing properties.

In recent years, in order to solve this problem, a buoy made of synthetic resin is widely used and widely used. The buoy made of synthetic resin has the advantage of superior durability compared to the buoy made of Styrofoam.

In addition, in order to increase the buoyancy of a buoy made of synthetic resin, a structure in which Styrofoam is filled inside and the outside is molded with polyethylene is disclosed in Korean Utility Model Registration No. 20-0389744.

The floating state may be maintained by the built-in styrofoam when the outer shape of the buoy is damaged, but there is a risk of secondary damage to the styrofoam, and there is a problem that the water phase may be contaminated by the fallen styrofoam. In addition, the buoyancy has a disadvantage in that the buoyancy cannot be adjusted because the filling amount of Styrofoam is fixed in the outer shape of the synthetic resin material.

In order to improve this problem, a sub-assembly (Republic of Korea Patent Publication No. 10-1910142) has been disclosed in which a tube having an expandable volume is accommodated while the gas is filled therein. By the way, in the sub-assembly, when the tube is filled with gas, a structure in which air between the tube and the inner peripheral surface of the sub-gut body is discharged on one side of the sub-gut body should be provided on one side of the sub-gut body, and the cap screwed to the sub-gut body is integrally connected with the tube It has the disadvantage of having to replace the whole in case of damage.
