Description

[Detailed Description of the Invention] The present invention relates to a float for a floating spacer of an oil fence that maintains the oil fence at a predetermined distance from a ship's hull or the like.

Traditionally, when a tanker or similar vessel is anchored in a port, oil fences are usually placed floating around the vessel at a predetermined distance in case of an oil spill or oil discharge. be.

However, since the deployed oil fence is not supported by anything, it is susceptible to the effects of wind, waves, and even currents, and it may shift to one side or partially lean against the ship's hull, causing it to fail as it should. Sometimes it didn't work.

In view of the above, the present invention has been devised to maintain an extended floating oil fence at a substantially constant distance from the ship's hull, etc., so that the oil fence can be extended effectively and favorably, and is particularly simple in construction. Furthermore, the purpose is to provide a product that has excellent shape-retaining strength and is easy to handle.

Next, embodiments of the present invention will be described based on the drawings.

In addition, the present invention has the float component 1 of the side portion as described above.
0 and the curved float component 20 at the corner are connected, but the float component 10 at the four sides is also applicable.
Float members of various shapes can be connected in a rectangular frame shape, such as by connecting them with a chisel, etc. In any case, in addition to arranging three rod-shaped bodies with a substantially inverted triangular cross section, Various methods can be implemented by arranging a plurality of rod-like bodies in parallel at predetermined intervals and holding them with flotation materials, such as arranging book rod-like bodies with a substantially rectangular cross section or arranging two rod-like bodies in parallel.

As the flotation materials 12 and 22, only the synthetic resin foam 13.23 or a synthetic resin foam 13.23 whose entire circumferential surface is covered with reinforced plastic can be used.

Instead of reinforced plastic, ordinary synthetic resin or thin metal plate can be used to cover the outer peripheral surface or the entire surface of the synthetic resin foam 13.23, but reinforced plastic is preferable from the viewpoint of strength, durability, etc. .

When reinforced plastic is used, the synthetic resin foam 13.23 which is the main material is a polyolefin resin, particularly a foam made of an olefin-styrene copolymer resin.

This copolymer resin of olefin and styrene is obtained by absorbing polyolefin resin particles and a vinyl aromatic monomer and polymerizing them in the presence of a catalyst.

Furthermore, as the main material of the flotation member 12, a buoyant material other than synthetic resin foam can be used, and in particular, a hollow body formed of reinforced plastic or the like can be used.

The present invention is constructed as described above, and as shown in FIG. It is used as a spacer to maintain a certain distance (for example, 10 m).

Therefore, since the spacer flow of the present invention) A has a substantially rectangular frame shape when viewed from above, when one side of the rectangle is brought into contact with the hull 40, the opposite side faces the oil fence 50, As a result, the float A is stably sandwiched between the hull 40 and the oil fence 50, and excessive floating is naturally regulated.
0 becomes longer, and no local tensile force is applied to the boom 50 as would be the case when the boom 50 is supported at one point.

Furthermore, flow) A of the present invention is constructed by arranging a plurality of rod-like bodies in parallel at predetermined intervals and connecting them with a float component formed by holding them with a flotation material such as synthetic resin foam. Because of this, no other connecting members are required to hold the rod-shaped bodies in parallel at a predetermined interval, which makes the structure simpler and lighter, and sufficient buoyancy can be maintained with the flotation members at several locations on each float component. .

In addition, each float component can be connected to each other by rod-shaped bodies, and the rod-shaped bodies are used as a skeleton to make the float strong and robust.

On the other hand, the flotation material is held securely in place by being held in place by the rod-shaped bodies forming the skeleton, and there is no risk of it coming off.

Furthermore, since the flow) A of the present invention has at least the outer surface of the flotation material on the side facing the ship formed in a vertical plane, the contact of the flow) A, especially the flotation material 12, with respect to the hull 40 is simplified, and the flotation material 12 is simplified. The material 12 is reinforced by the portion forming the vertical surface, and the flotation material 12 can be prevented from being damaged by contact with the hull 40, and the rod-shaped body can be held well and its durability can be increased.

In particular, if a fender is attached to the vertical surface of the flotation material,
The impact caused by contact with the hull 40 can be alleviated, and the durability of the flotation material, that is, the float can be further enhanced.

Therefore, by using the frame-shaped float of the present invention,
The oil fence can be maintained in a suitable expanded and floating state, and the oil fence can be reliably prevented from flowing excessively under the influence of wind, waves, or tidal currents, shifting to one side, or leaning against the ship's hull.

Furthermore, the present invention can be handled as a float component until it is connected into a rectangular frame shape, making it easy to transport and otherwise handle on land. It is also lightweight and has a simple structure. It is easy and contributes to material saving, and the float for an oil fence floating spacer of the present invention can be provided at an extremely low cost.
