Description

Adjustable Rich {ADJUSTABLE LENGTH FLOAT}

The present invention relates to a rich (, 子), by filling a styrofoam inside the pipe, such as PE or PP having a variety of length as a ready-made product to provide a rich variety of lengths easily while preventing the problem of environmental pollution due to the leakage of styrofoam fragments The present invention relates to a length-adjustable rich, which makes it easy to assemble without damage by external impacts and loads.

A rich man (floor, float, buoy, buoy or buoy) is a tool that uses buoyancy to float water facilities such as aquaculture facilities or aviation bridges necessary for aquaculture.

The currently used rich people are rich in styrofoam, rich in blow molding and injection molding structures using plastic materials, and tubular rich in rubber material in which air is injected.

In general, the most used styrofoam rich is a soft material has a problem that is easily broken by external impacts such as birds (파도), waves, working ships. The rich styrofoam is a very short lifespan due to damage to the tissue by strong ultraviolet light. In addition, the low density of the styrofoam material and the rough surface make it easy to attach foreign substances such as shellfish.The moisture penetrates inside the styrofoam, so the buoyancy drops rapidly over time. It is causing serious marine pollution and coastal pollution.

In addition, the styrofoam fragments broken out from the rich styrofoam act as a habitat for various pathogens, which is a cause of disease in farms. Even marine fish die from eating styrofoam pieces. As such, the rich styrofoam have a bad effect on the conservation of marine ecosystems and fish stocks. As a temporary solution to solve this problem, a product made by wrapping a styrofoam with PE material is used. 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.

As a technique for solving the problems of the rich styrofoam, "assembled float" (Korean Utility Model Publication No. 20-2011-0004023, Patent Document 1) has been published.

The technique allows the strength to be increased by assembling each other in divided laminations with respect to the central axis.

However, the above technique has a problem that the process of assembling the unit units together is cumbersome and cumbersome.

On the other hand, as a technique for preventing marine pollution by debris of styrofoam rich, "rich rich using polyurea resin and its manufacturing method" (Korea Patent Publication No. 10-0888397, Patent Document 2) has been published, Although the above technology may solve the environmental pollution problem, it also has not solved the fundamental problem of strength being brittle by external impact such as waves.

As a technique capable of solving the problems occurring in Patent Documents 1 and 2, "Boo-gu" (Korean Patent Publication No. 10-0994445, Patent Document 3) inserts a tube inside the case and sprays a foaming agent through the tube. It was strong from the impact and tried to solve the environmental pollution problem by preventing the internal resin from being discharged outward.

However, since the technique has to go through the process of supplying a blowing agent to the inside of the tube, the workability in the field is inferior, and if the tube becomes long, it is inevitably damaged by external force.

Therefore, while using a styrofoam, which is a lightweight material, while preventing the outflow thereof, it is easy to even workability, and the development of a ball having excellent strength is urgently needed.
