Description

Environmentally friendly buoys

The present invention is characterized in that the first divided body and the second divided body made of the compartment and the coupling part divided by the partition walls on the inner space are integrally formed by thermal fusion bonding so that the physical property is excellent, It is an eco-friendly product that helps to prevent marine pollution by reducing corrosion caused by waves, brine, sunlight and so on by using plastic material which is resistant to chemical and external environment. Friendly buoy, which is capable of producing buoys and has a long life span of buoys.

The buoy is provided with a function to set up a route to be installed for safe navigation of a ship, a position setting function for positioning various fishing boats or fishing boats in a predetermined position in a desired position in the sea water and a display function for easily grasping a place where the fishing boats are installed It is also called buoy or bulge.

The buoys currently used mainly include foam buoys, plastic buoys with blow molding and injection molding, and tubular buoys with air-filled rubber inside.

Generally, the most frequently used buoy is a foamed foam buoy as disclosed in Patent Document 1. As shown in Fig. 1, the foaming foam agent foam is foamed and molded by a foamed resin material such as EVA or PE, and the air chamber 4 inside the cylinder 2 is in communication with the outside and the recessed groove 6 is in the middle In the structure having the engagement hole 5, the cylinder 2 proposes a buoy made of a foamed foam material.

Such foamed foam materials are fragile and easily break down due to external impacts such as birds, waves, working lines, etc., when they are used at sea, or are easily damaged without being able to withstand water pressure when they are used on the sea floor. Also, since the structure is damaged by strong ultraviolet rays, the service life is very short, the density of the foamed foam material is low and the surface is rough, so that foreign substances such as various shellfishes are likely to adhere to the foamed foam. And the broken foam foam pieces float in the sea and do not easily disappear, causing serious marine pollution and coastal pollution.

In addition, the foamed foam pieces broken out from foamed foamed buoys act as habitats for various pathogens, which causes the pest disease. Even marine fish die from eating foam pieces. As such, foam foamed buoys have a negative impact on the conservation of marine ecosystems and fish stocks. As a temporary measure to solve this problem, a foamed foam is covered with a PE bag. However, these products can not prevent seawater penetration, and are easily corroded and damaged by sunlight and seawater, and the scrap fragments are also causing ocean pollution.

Patent Document 2 proposes a buoy having excellent workability and recycling characteristics. As shown in Figs. 2A and 2B, the buoy includes a rich body 2 formed by molding a polyolefin-based synthetic resin by a press foaming method; A tube 5 which is inserted into the hollow hollow 4 through the tube inlet 3 formed at one side of the rich body 2 and into which the air is injected; A cap 6 connected to the tube inlet 3 and a seal 7 sealing the gap between the cap 6 and the tube inlet 3.

However, even in the case of the above-mentioned subclause of Patent Document 2, the rich main body 2 is a synthetic resin foamed foam material, which is weak against external shocks as in the foamed foam buoy of Patent Document 1, The buoy itself may be distorted and broken due to expansion. Further, in the case of a tubular buoy of rubber material into which air is injected, there is a risk that the material may be deformed by strong ultraviolet rays, or the rubber tube may burst due to internal air expansion or stimulation of a sharp foreign object. If the rubber tube bursts like this, it loses its buoyancy and sinks into the water immediately, which can cause a serious obstacle to the culture.

As a buoy of the structure for improving the problem such as the buoy according to Patent Document 2, Patent Document 3 discloses, as a buoy (a) in which a hermetically sealed chamber is formed so as to withstand water pressure and the like at sea floor, as shown in Figs. 3A and 3B Molded in the form of a donut-shaped hermetically sealed chamber 2 by a through-hole 1 in the cylindrical outer circumferential surface, both side walls and the deep portion, and blow-molded using a plastic material so that the concave- The present invention proposes a buoy for fishing.

However, the above-mentioned conventional buoy is a structure in which a plurality of donut-shaped airtight chambers 2 and through holes 1 are formed inside the main body, and the structure is very complicated and is not suitable for blow molding. There is a problem in that a large number of defective products may be generated.

Therefore, as a buoy to prevent marine pollution and ecosystem damage caused by fragments of foamed foamed buoys, it is easy to manufacture without worrying that buoyancy is reduced or lost, and the demand for semi-permanently usable buoys is increasing.

Although the eco-friendly buoy according to the present invention has been described with respect to the engaging portion 40 composed of the first engaging portion 40a and the second engaging portion 40b, the present invention is not limited to this example, A main engaging portion 42 projecting from the center of the inner peripheral surface of the inner space 22 of the first divided body 20a and the second divided body 20b by forming a plurality of engaging portions in the body, And a first auxiliary coupling portion 44a and a second auxiliary coupling portion 44b spaced from both sides of the coupling portion 42. [ The height of the main engaging part 42 and the first engaging part 40a and the second engaging part 40b may be adjusted by the height of the first divided body 20a or the second divided body 20b, Which is formed so as to protrude more than the height of the partition wall 32, can be arbitrarily selected.

As described above, according to the eco-friendly buoy 10 of the present invention, the compartment 30 divided by the partition 32 is formed on the internal space 22 of the body portion 20, And the body portion 20 is made of a synthetic resin material such as polyethylene (PE) or polypropylene (PP), so that the durability of the buoy is long and corrosion due to waves, salt water, sunlight, This is an eco-friendly product that contributes to the prevention of marine pollution while enhancing the weatherability, chemical resistance and strength of buoys by reducing the phenomenon that the buoy is easy to manufacture by heat welding and there is almost no generation of defective products.

Although the eco-friendly buoy according to the preferred embodiment of the present invention has been described with reference to the above description and drawings, it should be understood that various changes and modifications may be made without departing from the scope of the present invention. It will be appreciated by those of ordinary skill in the art that this is possible.
