FOLDING OIL FENCE THAT CAN BE QUICKLY DEPLOYED AND RECOVERED}

The disclosed content is configured so that a plurality of fence units are jointly connected to enable stacked storage of the fence units, as well as to enable rapid automatic installation at sea by the elastic force of the tension spring provided inside the fence unit, so that crude oil at sea is possible. This relates to a folding oil fence that can be quickly deployed and recovered to prevent the spread of spilled crude oil in the event of a spill and to quickly collect it.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and is not admitted to be prior art by inclusion in this section.

When an oil spill occurs in the sea or river, oil or hazardous and noxious substances (HNS; Hazardous & Noxious Substances) float on the surface of seawater or river water and quickly spread to the surrounding area, causing serious environmental pollution. Therefore, when an oil or HNS spill occurs, it is important to quickly remove the spilled oil or HNS.

When oil spills, the usual methods are to spray an emulsifier on the surface of the water where the oil floats and let the oil sink to the bottom of the sea or river, or to remove the oil from the coast using absorbent cloth after the contaminants have spread to the coast. It is used. However, emulsifiers have the problem of causing secondary pollution by causing oil to sink to the bottom, and oil removal using adsorbent cloth can only be used after the spread of contaminants has already progressed significantly, preventing the spread of oil immediately after an oil spill occurs. Effective blocking and recovery technology is required.

Additionally, if a ship loaded with oil, such as an oil tanker, collides at sea and oil leaks into the sea, an oil fence can be used to prevent the spread of the spilled oil and to quickly collect it. there is.

According to the prior art, when an oil spill accident occurs at sea, an oil fence that functions as a barrier is loaded on a mobile ship and moved to the oil spill area, and then an oil fence is installed in the area surrounding the spilled oil by a tugboat, etc. By deploying the oil, the spread of oil is prevented, and the oil blocked by the oil fence is collected using a collection vessel that collects the spilled oil.

However, the oil fence according to the prior art was manually moved and placed by a tugboat, etc., making it difficult to place each unit of the oil fence in an appropriate position, and the oil fence simply had the function of a barrier. As a result, there was a problem in that the height could not be actively adjusted according to surrounding influences such as waves, wind, currents, or tsunamis, and due to the volume of the oil fence itself, it was difficult to store it or move it to the accident area.

In addition, in the case of conventional oil fences, not only are they bulky and heavy, but additional equipment such as a hydraulic peeling device is required for collection and storage, resulting in difficulties in transportation and storage.

In particular, in the case of solid oil fences using Styrofoam buoyancy bodies, they cannot be folded and stored, and the volume is quite large, causing storage problems.

As an example of such an oil fence, Republic of Korea Patent Publication No. 10-2018-0076882 (published on July 6, 2018) is a floating body that floats on the surface of the water, and is connected to the floating body to pass water and collect substances contained in the water. Disclosed is an oil fence comprising an oil separation membrane, wherein the oil separation membrane includes a porous material whose surface is treated to have hydrophilic properties.

In addition, Republic of Korea Patent Publication No. 10-2019-0136814 (published on December 10, 2019) uses a floating body that automatically expands using the elasticity of the buoyancy material, and uses a buoyancy material made of a thin plate-shaped composite material bent into a semicircle or circle. A self-inflating oil fence device that allows easy replacement of the buoyancy material and is configured to replace the buoyancy material by inserting and removing it from a pocket is disclosed.

However, in the case of the oil fence as described above, the oil fence is modularized and connected in multiple pieces to be folded in a zigzag manner so that it can be stored in a small volume, or it is automatically unfolded at sea to quickly prevent the spread of the spilled crude oil in the event of a crude oil spill at sea. Since it does not include a function to capture and capture oil fences, there are limits to its ability to quickly deploy and recover oil fences.

The second load member 143 is a plate-shaped metal plate attached to the outer surfaces of the third surface 113 and the fourth surface 114.

Additionally, the second load member 143 may be fastened to various specifications and arrangements depending on the specifications and size of the structure 110.

Therefore, it may be preferable that the hinge member 141, the first load member 142, and the second load member 143 corresponding to the load provider 140 are made of metal with a constant load.

The connection portion 200 is disposed on both ends of the fence unit 100 and connects the fence unit 100 with a neighboring fence unit 100.

In addition, the connection part 200 is a longitudinal connection member 210 provided with at least one connection hole 211 on both sides and connects the connection hole 211 with the connection hole 211 of the neighboring fence unit. It may include a coupling member 220.

In addition, the connecting member 210 has a length that allows each fence unit 100 to be connected at an interval that allows the fence unit 100 to be folded in a zigzag manner when stored.

If the length of the connecting member 210 is too short and the gap between the fence units 100 is narrow, it may become difficult for the fence units 100 to be stacked in a zigzag manner when stored, so the connecting member 210 must be of an appropriate length. It is configured so that the fence units 100 can be stacked in a zigzag manner.

The coupling member 220 is composed of a string or ring that is fastened after connecting the connecting hole 211 with the connecting hole 211 of the neighboring structure 110, and known materials can be applied without limitation. .

The outer shell 300 is configured to cover the outer peripheral surface of a plurality of fence units 100 connected by the connecting portion 200.

That is, the outer shell 300 is configured to cover the outer peripheral surface of a plurality of fence units 100 connected at regular intervals by the connecting portion 200, and both ends are formed by the first skirt portion by the first load member 142. It is coupled to (113b) and the second skirt portion (114b).

Additionally, the outer shell 300 may be made of a material such as PVC tarpaulin or PU.

Figure 7 is a configuration diagram showing the configuration of a webbing strap according to an embodiment of the disclosed content.

The folding oil fence 1, which can be quickly assembled and recovered according to an embodiment of the disclosed content, may further include a webbing string 400 attached in the longitudinal direction to the outer peripheral surface of the shell 300, as shown in FIG. 7. .

The webbing string 400 is configured in the longitudinal direction to be attached to the outer shell 300 so as to cover the edge side outer shell 300 of the fence unit 100.

Specifically, the webbing string 400 is used to increase the durability of the outer skin 300 on the corner portion of the structure 110 where the folding and unfolding process of the folding oil fence 1 is repeatedly performed for storage and installation. It is attached for the purpose of reinforcing the tension and external friction of the outer shell 300.

Accordingly, the webbing string 400 is attached to the outer shell 300 at the edge of the diamond-shaped structure 110 in the longitudinal direction, thereby preventing tearing or damage of the outer sheath 300.

Accordingly, it may be desirable for the webbing strap 400 to be made of a material that has excellent strength and does not stretch or tear under impact.

According to the disclosed embodiment, the folding oil fence capable of rapid installation and recovery is configured to enable rapid automatic installation at sea by the elastic force of the tension spring provided inside the fence unit, thereby preventing the oil spilled in the event of a crude oil spill at sea. It has the effect of preventing the spread of crude oil and enabling rapid capture.

In addition, since a plurality of fence units are connected by joints and then covered with an outer shell, the fence units can be folded in a zigzag manner and stored in a stack, which has the effect of significantly reducing the volume during storage.

In addition, since additional equipment such as hydraulic peeling devices are not required for collection and storage, it can be used for rapid initial response measures by marine police such as coast guard ships and dispatch stations, which has the effect of significantly improving marine pollution prevention.

In addition, each buoyancy body inside the oil fence is composed of a single module rather than being connected as a whole, which has the effect of preventing twisting of the oil fence.

In addition, the first and second skirt parts that are submerged below sea level can not only maintain their shape stably, but are also configured in an 'ㅅ' shape so that the lower part is open, so there is no problem of being submerged or losing function.

In addition, a hinge member fastened between the first slit and the second slit, a plate-shaped first load member attached to each of the first and second skirt parts, and a plate-shaped first load member attached to the outer surfaces of the third and fourth sides. The load providing part composed of the second load member serves as a weight for the structure, which has the effect of allowing the lower part of the structure, which is spread out in a diamond shape, to stand stably and upright below the water surface.

In addition, the third and fourth sides include water-receiving holes of a certain area, so that when the structure expands above the water surface, water flows smoothly into the structure, enabling rapid expansion.
