Between respective floating portions, a reinforcement component may be installed, while a tension belt is applied between the floating portion and the skit portion to improve tensile durability of the oil boom.

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. Such a large volume and additional equipment is required, and there is a disadvantage in that it takes a long time in the field and prevents the spread of oil or suspended substances at an early stage.

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 can be installed by connecting a plurality of buoyancy parts independently by a single unit of buoyancy of a certain size to solve the above problems, even if the buoyancy is maintained in the unit before and after the buoyancy is lost in any part The purpose is to provide a self-expanding oil boom that can prevent the loss of serious buoyancy, and to fold and store each unit in storage and movement in a stacked form, so that no additional equipment other than the loading device is required for movement and storage.

In order to achieve the above object, the present invention provides an auto-expandable oil boom having a structure in which each buoyancy portion is independently expanded to have buoyancy, and each buoyancy portion is folded based on the connection portion.

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

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

The buoyancy portion 1 has an independent expansion unit, the expansion unit is preferably used as the skeleton member 21, such as FRP rods that are durable against external shocks, resistant to corrosion, and light in weight. The skeleton member 21 constitutes the shape of the internal expansion unit as shown in FIG. 2, and each skeleton member is connected by the joint 1 (23) and the joint 2 (25) to form the overall shape. The overall shape is a hexagon having a long planar shape in the transverse direction, and the front shape is a rectangular shape having a long transverse direction.

A stopper 24 is provided inside the joint 1 23 that connects the transverse member and the longitudinal member to maintain a constant angle. 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 connected the spring is connected by the spring fixing member support line 27 to the joint 2 25 which connects a skeletal member of a horizontal direction. 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 planar shape when the internal expansion unit is compressed.

When the internal expansion unit is compressed, there is a case where the shape does not fold 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 internal expansion unit is packaged by the endothelial 11, wherein the structural members 21 and 21 'are 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 inner shell (11) and the outer shell separately so that buoyancy can be preserved into the inner shell 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 intake 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 adopts a check valve in which suction and discharge are performed 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, the outlet 6 of the outer shell to minimize the penetration of the foreign matter into the internal expansion unit.

Since 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.

The self-expanding oil boom of the present invention is divided into a buoyancy portion 1 and a skirt portion 2.

The skirt portion 2 prevents oil or floating material from leaking to the bottom of the buoyancy portion.

Ballast chains (3) are installed at the lower end of the skirt (2) to apply a load to the armed forces.

The tension belt 32 is provided in the longitudinal direction at the connection portion of the buoyancy portion and the skirt portion to add durability to the tensile load.

5 is an example of installation of the automatic expansion oil boom of the present invention. Independent expansion units are installed in the longitudinal direction.

According to the above description, the present invention can be installed quickly at the time of installation by providing an auto-expansion oil boom, and having an independent expansion unit is less likely to lead to an overall loss of buoyancy even if there is a local breakage during installation. Even when it is stored, stability is good because a constant tensile force acts in the longitudinal direction of the spring. 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.
