JP6731591B2 - Multiple oil fence with leak function - Google Patents

Description

The present invention relates to an oil fence used to prevent the diffusion of petroleum when it leaks or flows out.

Conventionally, when oil leaks and flows out on the surface of water such as rivers, lakes, and seas due to an accident or the like, an oil fence has been spread in the water area to prevent the diffusion.
The oil fence generally uses a single strip, but in this case, the skirt of the fence blows up depending on the flow due to the fluid resistance, and there is a drawback in that the shape cannot be maintained to secure oil. Also, in special cases, there are cases where multiple expansion is performed. However, in the case of multiple expansion, the space could not be maintained between the oil fences, which was substantially the same as in the case of single expansion.

Therefore, there has been a demand for an oil fence that does not leak petroleum even when the oil fence is spread over a flowing water surface and that can collect and store a large amount of petroleum that has leaked out in the case of multiple expansion.

Therefore, as a result of various studies, the present inventor has found that at least two oil fences are provided with a space between the oil fences, and a spacer is provided in the longitudinal direction of the space to provide a partition portion. We have completed a multiple oil fence with a prevention function.

According to the present invention, by providing a plurality of compartments between multiple oil fences, the backwater action acts on the second and subsequent oil fences, so that the compartments can be kept in a quiet state. The part serves as a storage part for petroleum and can hold a large amount of spilled oil (petroleum), and can also prevent leakage of spilled oil from the lower end of the oil fence.

It is a front view which shows the edge part of a spacer. It is a front view which shows a locking metal fitting. It is a front view which shows the spacer of another aspect. It is a perspective view which shows the spacer of another aspect. It is a top view at the time of spreading the multiple oil fence of this invention in flowing water. It is a top view which shows the spreading|diffusion method which has a balloon type oil collecting part with the multiple oil fence of this invention. It is a top view which shows the spreading method which has a semi-balloon type oil collecting part in the multiple oil fence of this invention. It is a top view which shows the spreading method which has a Y continuous type oil collecting part in the multiple oil fence of this invention.

FIG. 1 is a plan view of a case where two oil fences are stretched as in the conventional case in flowing water. Conventionally, even if the oil fence 1 and the oil fence 2 are installed with a space therebetween, the oil fence 1 and the oil fence 2 come close to each other due to the water flow, and the purpose of substantially double spreading cannot be achieved. In such a case, a part of the oil collected in the oil sump 3 of the oil fence 1 leaks from the lower edge of the oil fence 1 and is collected in one place of the oil sump 4 of the oil fence 2 extended backward. It was oiled. However, since the space of the oil reservoir 4 of the oil fence 2 is limited, the oil once collected leaks from the lower edge of the oil fence 2 and complete oil recovery is impossible.
In the present invention, as shown in FIG. 2, a space 7 is provided between the oil fences 5 and 6, and both ends of a spacer 9 having a float 8 in the space 7 are fixed to the adjacent oil fences. Therefore, the partition portion 10 can be provided.

In the spacer 9 used in the present invention, as shown in FIG. 3, the float 8 is covered with a base cloth 11, and the edge portion 12 is fixed by sewing or the like. Further, in order to fix the float 8, both side portions of the float 8 are also sealed by sewing or the like. Further, the spacer 9 can be provided with an arbitrary number of floats 8 depending on the width thereof.
The spacer 9 thus configured has its both end portions 13 and 14 integrally fixed by sewing or the like between the floats of the opposing oil fences. The oil fence of the present invention can be constructed by multiplying the spacers 9 at appropriate intervals in consideration of the situation of the installation place.

Further, as shown in FIG. 4, the spacer 9 of the present invention is folded into both ends 13 and 14 (only one is shown in the drawing) to form a bag-like shape 15, and the folded edge 16 is sealed by sewing or the like to form a spacer. Insertion openings 18 for inserting the locking metal fittings 17 can be provided at both ends of 9.
The locking metal fitting 17 used for integrating the spacer 9 with the oil fence is, for example, a pin-shaped fitting as shown in FIG. 5, and straight portions are inserted into the insertion opening 18 from the upper and lower portions of the spacer 9, At the same time, sandwich it between the floats of the oil fence.

As another aspect of the spacer 9, as shown in FIG. 6, the spacer 9 is formed by covering the flat plate-like float F with a base fabric that is folded in two and sewing the three sides. May be sewn in the longitudinal direction with a space inside the both ends thereof, or both ends 13 and 14 may be folded back and sealed in a bag shape to provide an insertion opening 18 to form a flat spacer 9. it can. The spacer 9 using the flat-shaped float is suitable because it is not bulky when it is stored.
Further, as shown in FIG. 7, a plastic case 19 is provided with a locking portion 20 and both end portions are provided with indicating portions 21 for inserting and holding the locking metal fittings 17, and a flat plate-like shape is provided inside such a plastic case type spacer 9. The plastic case case type spacer 9 can be prepared by housing the float F, closing it, and then fixing the locking portion 20.

By using the detachable spacer 9 in the oil fence as described above, for example, a multiple oil fence having a structure as shown in FIG. 8 can be obtained.
Further, using the multiple oil fence of the present invention, a spreading method having a balloon type oil collecting portion as shown in FIG. 9 or a spreading method having a semi-balloon type oil collecting portion as shown in FIG. 10 or as shown in FIG. It can be used as a spreading method having a continuous Y-type oil collecting section. As a spreading method having the balloon type oil collecting portion, a balloon type shape can be formed by fixing the balloon type both ends 22, 23 with a net body 24 or the like. The balloon type can have a large oil collecting part.
In the present invention, since an arbitrary number of partition portions can be provided by using the removable spacer 9, the partition portions can be set to an appropriate number according to the amount of oil that has flown out.

As the material used for the spacer 9 of the present invention, various base cloths such as nylon base cloth, polyester base cloth, vinyl chloride coated nylon base cloth and the like are used, as well as chloroprene rubber sheet, synthetic resin sheet, synthetic resin sheet. A molded body or the like can be used.
