Self-expanding oil boom using double space paper {SELF INFLATABLE OIL BOOM USING DOUBLE SPACE PAPER}

The present invention relates to an auto-expandable oil boom using a double space paper, and more particularly, to an auto-expandable oil boom using a double space paper, which is excellent in safety and durability, reduces electric load and recovery time, and is easy to maintain. will be.

As maritime traffic increases, many maritime accidents occur due to stranding or collision of ships. Disaster accidents are characterized by the seriousness of environmental pollution due to oil spills as well as loss of life and property. Spilled oil spreads rapidly under the influence of wind, waves, and algae, so it must be removed early in order to minimize damage.

There are two ways to control oil at sea. One way is to use dispersants in a chemical way. However, this method causes secondary environmental pollution and requires great care when used. Alternatively, there is a physical method of using oil booms to prevent oil from spreading and then using a skimmer to recover the oil.

The latter method is preferable to the former method in terms of protecting the marine environment because it is literally a physical recovery method. Therefore, it can be said to be the most effective method if efficient control equipment and excellent control personnel are secured. In particular, the oil boom, which is the most basic and important equipment for oil recovery, not only has the ability to effectively block the spread of oil leaked at sea, but also can be installed quickly, easy to store, and convenient to handle. Light weight construction should be provided.

The conventional oil booms are largely classified into fence type and curtain type oil booms.

The basic structure of the curtain oil boom, which is most widely used, is a float 10 which gives the oil boom to float on the water surface, as shown in FIGS. 1A and 1B, and the water surface to prevent the oil from overflowing the oil boom. The freeboard 20 extending from the 6 to a certain height, the skirt 30 which is installed under the floating body 10 and captures oil, and the oil boom are submerged under the water surface. It includes a ballast 40 which serves to improve the performance of the oil boom or to keep the skirt in the vertical direction. At this time, the ballast 40 is usually used a chain or lead.

The curtain type oil boom has a solid type using a material such as styrol foam and an inflatable type for injecting air into the air chamber according to the characteristics of the floating body, and the inflatable type is a forced inflatable type and an oil boom using a compressor or the like depending on the method of injecting air. There is an automatic inflatable in which air is injected into the air chamber at the same time as the installation.

The solid oil boom most widely used in the art uses a float 12 wrapped with a solid oil such as foamed styrofoam 22 in an oil resistant fibrous (PVC) cloth, as shown in FIG. 2A. In the solid oil boom, an oil boom having a length of several tens of meters is connected in series by the connecting device 50.

But. Conventional solid oil booms are not only inconvenient to be bulky and inconvenient to use, but also require large storage locations, weak durability, and short lifespan, since the oil boom is usually several hundred meters in length. In addition, the styrofoam 22 has a problem that it is not easy to dispose because the material does not rot well.

On the other hand, a conventional air inflatable oil boom has an air chamber 23 formed by, for example, a rubber coated cloth instead of buoyant styrofoam as shown in FIG. 2B. When the oil boom is installed, the air chamber 23 is introduced into the air by a blower to prevent oil diffusion while maintaining the shape of the floating body, and when the oil boom is removed, the air chamber 23 Air injected into the inside is discharged to the outside. As the material of the fabric, PVC, PU, hypalon, neoprene and the like can be used.

However, the conventional air-inflatable oil boom requires a blower for blowing air, and when the cloth is damaged by a sharp object floating on the water surface, air escapes and loses buoyancy, thereby losing its function as an oil boom. In addition, since the air blast and suction of the air per unit air cell (Air Cell), the length of the oil boom has a long length or recovery time, a relatively large number of manpower is inefficient and not able to respond quickly to the oil spill accident.

Conventional self-expanding oil booms, as shown in Figs. 2c and 2d, hold the plastic frame 24 in the form of a four-section link and expand the frame 24 to expand the air chamber 23. In order to include a pair of coil springs 26 connected vertically to the upper and lower frames on one side. When the frame 24 is extended by the spring 26, the pressure difference between the inside and the outside of the air chamber caused by the sudden volume change of the air chamber 23 causes the outside air to be injected into the inside. A check valve is provided above the air chamber for this air injection. And, in order to prevent the oil from overflowing the oil boom in case the air chamber is damaged, the air chamber 23 is divided into a plurality of chambers by the flexible partition wall 28.

In the self-expanding oil boom, the frame is stored in a folded state, i.e., in a tensioned state during storage, and in installation, the frame is opened in a square by the elastic force of the pair of springs 26, and the air chamber Due to the pressure difference between the inside and outside of the outside air is introduced into the air chamber through the check valve 14 buoyancy is generated.

However, the conventional automatic inflatable oil boom had weaknesses such as damage to the cloth by the spring 26 and the like, and failure of the valve 14 and the frame 24. In addition, the shape of the support body is limited because it is in the shape of a rhombus with relatively poor movement performance due to waves.

In addition, the internal structural material installed in the flotation body has a disadvantage in that the durability is very weak bar due to structurally external force and impact in the process of deploying the oil boom or (Winding) to the reel device.

In case of damage to the internal structural material, the internal structural material should be replaced or repaired as if the outer skin was cut out and operated, and the cut outer parts have difficulty in adhesive restoration using different fabrics. It is accompanied by an increase.

In addition, since air is sucked in (when fully charged) or discharged (when collected) through a valve having a limited diameter provided in the support body, the time required for full length or recovery is long.

In addition, the storage requires space corresponding to the internal structural material, the structure of the oil boom is complicated and the weight is increased.

In addition, if the shell (single layer) of the support body is damaged (pore), the internal air immediately falls out and becomes submerged, thereby losing its function as an oil boom.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to form a floating body having the first and second air chambers by a double space paper, so that the safety and durability are excellent, and the electric field and recovery time are improved. It is to provide an auto-expandable oil boom using a double space paper that is easy to reduce and maintain.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

Figure 3 is an internal side view of the automatic expansion oil boom using a double space according to the present invention, Figure 4 is a front view of FIG.

The auto-expandable oil boom using the double space paper according to the present invention, as shown in FIG. 3 and FIG. 4, the support body forming the first and second air chambers 121 and 123 by the double space paper. It comprises the 101, the skirt 103 connected in the longitudinal direction below the support body 101, and the ballast 107 provided in the lower end of the skirt 103.

The support body 101 includes a plurality of partition wells 113 partitioning the first and second air chambers 121 and 123 formed by the double space paper and the inside of the first air chamber 121 at predetermined intervals. And an air supply hose installed inside the first air chamber 121 to supply compressed air to the first air chamber 121 and the second air chamber 123 partitioned by the partition well 113. 109a and 109b are provided.

In addition, the support body 101 is formed by folding the double space sheet in half and then tying it with a rope 127 at a predetermined height such that the first air chamber 121 and the second air chamber 123 are formed. . At this time, the rope 127 is formed in a bonded state at a predetermined interval inside the double space. The double space paper forming the second air chamber 123 may be formed using PVC, PU, hypalon, neoprene, and the like. The fabric is formed like a thread. As already known, the technique of weaving the fabric is formed by coating PVC, PU (polyurethane) and the like on a polyester weave, for example. Therefore, when air enters the second air chamber 123 of the double space, even if one side of the double space is open, the air is slowly released by the fabric.

And, when the first air chamber 121 is a predetermined pressure by the compressed air supplied through the air supply hose (109a, 109b), the support body 101, the first air chamber 121 Compressed air therein flows down through a gap between the rope 127 and the rope 127 which is bundled at a predetermined interval inside the support body 101. Then, the compressed air introduced below is supplied into the second air chamber 123 of the double space through the air through hole 125 shown in FIG.

The air supply hoses 109a and 109b are installed in the first air chamber 121 by the length of the support body 101 and form a plurality of air outlets (not shown) at predetermined intervals.

Reference numeral 109c, which is not described in the drawing, denotes a hose fixing ring that holds the positions of the air supply hoses 109a and 109b, and reference numerals 111a to 111c denote tension members. The tension members 111a to 111c are connected to the upper portion of the support body 101, the inside of the mini skirt 105, and the ballast 107, respectively, to support the auto-expandable oil boom using the double space. Or it serves to hold tight.

Referring to the operation of the automatic expansion oil boom using a double space according to the present invention having the above configuration as follows.

First, the tip of an auto-expandable oil boom (also called an oil boom) using a double space wound on a reel device (not shown) is towed from the ship. When the tip of the oil boom touches the surface of the water, the air valve (not shown) installed in the reel unit is opened to send compressed air to the air supply hoses 109a and 109b.

The compressed air supplied through the air supply hoses 109a and 109b is supplied from the tip of the oil boom toward the reel unit to fill the support body 101 with air. At this time, the compressed air supplied through the air supply hoses 109a and 109b enters into the first air chamber 121. When the inside of the first air chamber 121 expands to reach a predetermined pressure, the compressed air inside the first air chamber 121 is bound to the inside of the support body 101 at a predetermined interval (rope) It flows down through the gap between the 127 and the rope 127. Then, the compressed air introduced below is supplied into the second air chamber 123 of the double space through the air through hole 125 shown in FIG. As a result, the second air chamber 123 is also inflated by the compressed air.

In the above-described order, the expansion is serially performed in adjacent partitions formed at predetermined intervals inside the support body 101. As a result, the automatically expanding oil boom using the double space paper maintains its normal shape.

When the full length of the automatic expansion oil boom using the double space paper is completed, the air valve is closed.

Then, when the recovery operation of the spilled oil is completed, the reel unit is driven to recover the auto-expandable oil boom using the double space paper. At this time, the oil boom is wound up by the rotation of the reel device while the support body 101 is vertically stretched to the water surface is pulled up obliquely to the side. At this time, a gap is formed between the rope 127 and the rope 127, which are bundled at a predetermined interval inside the support body 101, and a space is formed, and this space is located in the first air chamber 121. Compressed air will escape. Then, the compressed air in the second air chamber 123 exits through the double space paper which is open at the lower end of the support body 101. The compressed air in the second air chamber 123 is completely released by the force pushing the oil boom when the oil boom is wound on the reel device.

Accordingly, the auto-expandable oil boom using the double space paper is compressed air and residues inside the first and second air chambers 121 and 123 only by winding the reel unit without a separate procedure. Can be discharged completely.

As such, the auto-expandable oil boom using the double space according to the present invention can be made to a desired length by simply connecting several sets (for example, one set is 300m).

In addition, the self-expanding oil boom using the double space paper according to the present invention is because the support body 101 forms a double-ply air chamber (first and second air chambers) by the double space paper. Even if the outer wall (second air chamber) of the sieve 101 breaks, the formation of the first air chamber 121 is maintained as it is and thus does not cause a loss of function of the oil boom.

If the first air chamber 121 of the support body 101 is ruptured and flooded, only the cell damaged by the partition well 113 (the space between the partition well and the partition well) is flooded and the entire oil boom The safety level is dramatically increased because it is designed with three levels of safety.

In addition, since only the air supply hoses 109a and 109b are provided inside the support body 101, the damage factor and the weight increase factor due to the internal structure are minimized, so that the total weight is reduced and maintenance cost is almost unnecessary. It was.

In addition, since the compressed air is injected step by step by the partition well 113 from the end of the oil boom during the oil boom battle, the stability of the oil boom and the like is greatly improved.

In addition, by making a double space paper manufactured by a special weaving method, compared to the conventional automatic inflatable oil boom made in a single layer, the durability and tensile strength improved more than twice.

In addition, while the support body of the conventional oil boom is closed, the self-expanding oil boom using the double space of the present invention is because the mini scud 105 is designed to be kept open by external water surface and water pressure. Since the discharge of air through the mini skirt 103 is self-contained, there is no discharge resistance of the internal air at the time of recovery of the oil boom, and thus the recovery speed is very fast.

In addition, the automatic expansion oil boom using the double space paper according to the present invention does not require skill in operation. Therefore, even a single novice can perform the operation and recovery of the oil boom.

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be possible to various modifications, changes, additions, etc. within the spirit and scope of the present invention, these modifications and changes belong to the following utility model registration claims Should be seen.

As described above, according to the self-expansion type oil boom using the double space according to the present invention, it is possible to shorten the time required for the oil boom electric field and recovery, it is possible to respond quickly to the oil spill accident. In addition, the safety and durability of the oil boom by the advanced manufacturing techniques has been significantly improved.

In addition, there is an import substitution effect according to the import dependency of the automatic expansion oil boom.

In addition, since the structure is designed in a simple structure, the maintenance cost is reduced by minimizing damage factors.

In addition, it can be easily repaired when damage (pore) occurs by external force, there is an effect that does not cause secondary damage by surgical repair.
