Description

[0001] Multifunctional eco-friendly buoy and method for making the buoy [

The present invention relates to buoys in which various aquaculture styles and installation locations are identified;

More particularly, the present invention relates to a method for manufacturing a buoy, which is capable of binding ropes in various ways and is composed of an environmentally friendly flexible synthetic resin member and a heat shrinkable synthetic resin member and coated with a polyurea coating layer, Flexibility, impact resistance, corrosion resistance, weather resistance and abrasion resistance;

There are various types of buoys that are essential for various aquaculture types, of which foam polystyrene (styrofoam) or blower-molded synthetic resin is the mainstream.

These buoys take the form of a cylinder and have grooves extending in the circumferential direction on the outer circumferential surface thereof so as to be able to surround the rope. However, in the case of buoys made of styrofoam, since the physical properties of the styrofoam itself are weak and broken, the rope-wrapped portion easily breaks due to the influence of waves and winds, for example, during prolonged use.

In addition, the damaged buoy can not bind the rope anymore, and therefore the buoyancy is too weak. Such a buoy buoy is not only polluting the environment but also being pushed to the shore by waves or winds, And the like.

In order to solve the above-mentioned problem, Korean Patent Registration No. 10-1624681 (side welding apparatus and method thereof) has been disclosed.

In the conventional environmentally friendly buoy introduced in the above publication, the side cover is attached to both side portions of the styrofoam body, and the outer circumferential surface is covered with the heat shrinkable sheet to reinforce the strength of the styrofoam.

However, the above-mentioned conventional environmentally friendly buoy has a disadvantage that the side cover and the heat-shrinkable sheet are easily separated from each other unexpectedly. When manufacturing, the welding roller is used to fuse as tightly as possible, but the welded portion is worn without being able to overcome the effects of continuous waves and wind during use.

When the fused portion is completely separated, the side cover is detached from the styrofoam body, and the styrofoam is intact. If the detached side cover is not immediately collected, it floats in the seawater or accumulates on the sea floor.

In addition, the styrofoam exposed to seawater also gradually breaks, and microscopic debris spreads to the surrounding area, which greatly pollutes the seawater, and microscopic styrofoam pieces floating in the seawater eat fish, resulting in a problem of secondary damage to humans have.

As shown in the drawing, the multi-functional eco-friendly buoy manufacturing method according to the present embodiment, in which various aquaculture styles and installation locations are identified,

A buoyant body preparation step 100, a perforation step 102, a primary cover step 104, a secondary cover step 106, and a heating step 108.

First, the buoyant body preparing step 100 is a process of preparing the buoyant body 11 to be used as a buoy.

The material, size, or shape of the buoyant body 11 may vary widely and is preferably composed of a cylindrical styrofoam member made of a polystyrene resin material; A polyethylene resin or a polypropylene resin or a vinyl chloride resin or a member made of fiber-reinforced plastic or rubber is used.

The buoyant body (11) has an outer peripheral surface (11d) having a constant diameter and a flat side surface (11c) formed on both side portions of the outer peripheral surface. 1A is a sectional view for the sake of convenience, the buoyant body 11 takes the form of a cylinder having an insertion tube 13 at the center shaft as shown in FIG. Reference numeral 11a denotes a circumferential groove. The circumferential groove 11a is a groove for binding ropes and the like.

If the buoyant body 11 is prepared through the buoyant body preparation step 100, a boring step 102 is performed. The perforating step 102 is a step of forming a through hole 11b having a predetermined inner diameter at the center shaft portion of the buoyant body 11 and extending straight. Both ends of the through-hole 11b are located at the center of the side surface 11c. The inner diameter of the through hole 11b may vary depending on the size of the buoyant body 11, and may be, for example, about 10 cm.

The subsequent primary cover step 104 is a process of covering the inner circumferential surface of the through hole 11b and the side surface 11c of the buoyancy member using a flexible synthetic resin member. The flexibility refers to a property of melting and fusion bonding when heat is applied from the outside.

The flexible synthetic resin member is constituted, for example, as a tube-shaped cover and a cylindrical insertion tube made of polyethylene or polypropylene resin,

A hollow insertion tube 13 inserted into the through hole 11b and having both ends protruded to the outside of the through hole 11b and a hollow insertion tube 13 which is in the form of a disk and is in close contact with the both side surfaces 11c, And a cover (15).
