Description

{DURABILITY IMPROVED BUOY}

The present invention provides a structure for preventing corrosion of an object floating on a water surface by additionally laminating another barrier film in a structure to be detachably fastened to the barrier structure to enhance the blocking effect against ultraviolet rays to prevent corrosion of the object And which improves durability that can be freely interchanged during identification conversion or contamination.

Generally, there is no uniform standard for marking the boundary area of the farm or fishery area, and the installation location information of the farm or fishing ground is not provided to the navigator, so that the accident involving the fishing ground is gradually increasing.

Recently, the IALA (International Association of Navigation Marks) has recommended to arrange navigation signs on farms of more than a certain size to prevent accidents. In addition, the Ministry of Maritime Affairs and Fisheries There is a plan.

Most commonly, 'buoys' are used. Buoys, commonly used in marine farms for boundary marking, are sometimes referred to as buoys or buoys and are used to indicate the course of a ship or to be used in fisheries, It is used to display the area (position) of various fishing gears.

For example, foam is most widely used as a buoy, and the foam is made by injecting a foamed material of a synthetic resin into a mold and foaming it. Since the foam itself is lower in specific gravity than water, it floats easily on the sea surface, In the foaming process in which the mold is opened during the production of the foam, a large number of closed pores are formed in the foam, and the buoyancy function of the foam is improved by the closed pores.

However, the foam may be easily swollen and broken by being hit by a wave or a working boat, and the bonding tissue may be contaminated or broken by attachment or penetration of marine organisms, and the broken foam pieces easily float in the ocean or a reservoir There is a problem that environmental pollution is caused.

To solve these problems, a buoy cover for fishery which is manufactured to wrap a foam has been proposed. However, when the buoy cover is used in a sea cage farm, the buoy cover is contaminated when it is used for one year to two years due to ultraviolet rays and salinity. And thus the buoy cover is decomposed to pollute the sea.
