Description

Auto-Inflation Type Oil Boom}

The present invention aims to suppress the diffusion of oil or suspended substances spilled on the water surface, and relates to an auto-expansion oil boom that automatically expands upon installation on the water surface.

Oil and suspended solids spilled on the surface of the water must be prevented early to reduce their damage.

To this end, the existing oil boom is a device that includes a solid buoyancy or a balloon-type device for injecting air. These oil booms are bulky and require additional equipment, and take a long time in the field, so there is a disadvantage in that they do not prevent the spread of oil or suspended matter early.

The oil boom has been developed to automatically inhale external air during installation to improve this, but there is a problem in the durability, especially in the case of the existing auto-expansion type because of the internal damage is penetrated by several tens of meters. This results in overall loss of functionality. In addition, since it is wound around a rotary reel during movement and storage, an unbalanced force is often applied to the internal structure. Rotary reels are bulky and require additional equipment to operate them.

The present invention proposes a structure for connecting a plurality of buoyancy parts independently by installing a single buoyancy part of a certain size to solve the above problems, so that buoyancy is maintained in the unit before and after any buoyancy is lost In this case, the purpose of the present invention is to provide a self-expanding oil boom that prevents the loss of serious buoyancy, and folds and stores each unit in a stacked form during storage and movement, thus eliminating the need for additional equipment except for the loading device. .

In order to achieve the above object, the present invention is to connect a plurality of buoyancy parts independently by a unit of buoyancy portion of a certain size, each buoyancy portion can be independently inflated by each expansion unit to float on the water Has a buoyant buoyancy, each buoyancy portion is configured to be folded based on the connection site, the lower portion of the buoyancy portion is formed of a structure that is formed in the skirt submerged in the water blocking film to prevent the spread of contamination while automatically expanding Presents an automatic inflatable oil boom configured to form a.

When described in more detail based on the accompanying drawings of a preferred embodiment of the present invention.

1 is a shape and internal structure of the buoyancy constituting the automatic expansion oil boom according to the present invention.

According to this, the buoyancy portion (1) is made of an expansion unit (1a) consisting of a skeleton structure that is automatically unfolded by the restoring force of the spring in the folded state and the covering material (1b) is covered and coupled in the form of wrapping the expansion unit from the outside and , The skirt portion 2 is composed of a curtain-type barrier film (2a) formed in the lower center of the covering material in series with the coating material and the weight (2b) for holding the barrier film tightly connected to each buoyancy portion and skirt portion This constitutes the overall oil boom. In the embodiment according to each drawing, the expansion unit 1a has a durability against external impact, is resistant to corrosion, and uses a lightweight FRP rod or the like as a skeleton member, and connects each skeleton member to a joint to form a skeleton. It consists of one structure. Each of the skeletal members 21 constituting the shape of the expansion unit is connected by the joint 1 (23) and the joint 2 (25) to form an overall shape, the overall shape is a hexagon with a long horizontal plane in the transverse direction, the front The shape is a rectangular shape long in the transverse direction, each joint has a folding structure so that each skeleton member can be folded in the state that the skeleton member is coupled.

The stopper 24 is provided in the inner side of the joint 1 23 which connects the horizontal member and the longitudinal member which comprise a skeleton member so that a fixed angle can be maintained. The stoppers 24 are provided at eight places along the outline of the skeleton structure. (Upper four places, lower four places)

The spring fixing member 26 which directly connects the spring is connected to the joint 2 25 which connects the skeletal member of the horizontal direction by the spring fixing member support line 27. The spring 22 is fixed to two spring fixing members 26. Two or more springs 22 are installed along the spring fixing member 26.

When the internal expansion unit is compressed, the spring holding member 26 is pushed outward in the lateral direction and generates tension in the spring 22.

4 is a state in which the spring 22 is tensioned as a planar shape when the internal expansion unit is compressed, and a force is applied to maintain the compressed state from the outside. It is in an unfolded state. Since the outside of the inner expansion unit is wrapped by the covering material, the external force that compresses the expansion unit by tensioning the spring becomes the force that folds each connecting portion of the covering material. As it is removed, the expansion unit automatically expands due to the restoring force of the spring, and the force inflates the cladding to give buoyancy. The covering material surrounding the expansion unit is made of a double structure of the inner skin (11) and the outer skin (4). Therefore, the inner expansion unit is packaged by the endothelial 11, wherein each member 21, 25 constituting the frame is installed to be fixed to the endothelial. The inner expansion unit packaged with the inner shell 11 is inserted into the outer shell 4.

By installing the endothelium 11 and the outer shell separately, it is possible to preserve buoyancy into the endothelium even when local damage occurs to the outer shell.

The endothelial-wrapped automatic expansion unit is designed to be replaced in case of breakage. To this end, the outer cover 4 is provided with a zipper 5, and a cover 7 is installed at the top of the zipper to prevent the inflow of water. Since the inner skin does not directly contact oil, it is preferable to use PVC vinyl, and the outer skin is urethane coated vinyl.

The inflow of air according to the expansion of the internal expansion unit is made through the air inlet and outlet 6 installed in the shell 4. The air intake outlet is covered with a cover to prevent water from penetrating from the outside, or it uses a check valve that intakes and discharges at a constant pressure.

Endothelial 11 is also provided with air inlet, outlet 12 for air intake, discharge. At this time, the air intake of the endothelium, the outlet 12 is staggered position with the air intake, outlet 6 of the outer shell to minimize the penetration of the foreign matter into the internal expansion unit.

Since the connecting member between each buoyancy portion 1 is connected only to the shell 4, a buoyancy portion joint reinforcement portion 31 is provided to reinforce the strength of this portion. This part inserts a member having strength therein and installs a reinforcing material in the shell 4. When the internal expansion unit is compressed, the shape may not be folded in one direction in the transverse direction due to the tension of the spring 22. Therefore, in order to prevent this, the endothelial fixing string 29 which fixes the spring fixing member 26 and the endothelial 11 moves on the transverse skeletal member 21 'in the form of a slider and maintains the distance of the guide ( 28) is installed. In the case where all the skeletons are firmly held on the endothelium, the twisting of the structural shape during the compression is less likely, and thus the installation of the guide 28 can be omitted.

The skirt portion 2 is for preventing oil or floating material from leaking to the lower end of the buoyancy portion. The skirt portion 2a formed downward in the center of the lower portion of the outer shell and the weight formed at the lower portion of the barrier layer so that the barrier layer is submerged into the water surface. It consists of (2b), in the embodiment according to the present invention is configured so that the ballast chain (3) to perform the weight role, the ballast chain provides an advantage that can be easily folded when folding the connection portion of the buoyancy portion do. 5 is an example of installation of the self-expansion oil boom of the present invention. Independent buoyancy unit is installed in the longitudinal direction, and the connection unit connecting each buoyancy unit is folded and when the inner expansion unit is in a compressed storage state when the folded area is used in use, the expansion unit inside expands and the air flows into the inner and outer skin instantaneously. Inflow and buoyancy, and at the same time by the action of the ballast chain skirt spreads below the water surface to form a barrier that prevents the spread of contamination very quickly and simply.

According to the above description, the present invention can be installed quickly at the time of installation by providing an auto-expandable oil boom, and having an independent buoyancy portion is less likely to lead to a total loss of buoyancy even if there is a local breakage during installation. Even during storage, a constant tensile force acts in the longitudinal direction of the spring of the expansion unit, so stability is good. In addition, since it is stored and transported in a stacked manner, there is no need for additional equipment and the volume of occupancy is small compared to the case of storing in a rotary reel.
