Description

[Detailed Description of the Invention] The present invention relates to an oil fence adapter, and more particularly to an oil fence adapter that reduces labor and efficiently connects an oil fence using a one-way fastener.

Various types of oil fences have been used so far to prevent the spread of oil spilled into the ocean, and it is stipulated that fasteners be used to connect them.

However, with this fastener connection method, (1) the fastener is easily damaged, making connection impossible or difficult;

(2) When the weather worsens, it becomes difficult to connect zippers due to the effects of waves, etc. In this case, the oil fence is hoisted onto the ship and connected, but large fences are heavy and this work is not easy.

As a result, salvage, connection and installation may take a long time, during which time the spilled oil may spread.

(3) When it is necessary to put a recovery vessel inside the oil fence to recover spilled oil surrounded by an oil fence, and when it is necessary to forcibly lead out the spilled oil inside the oil fence and recover it. There are various drawbacks, such as sometimes not being able to take immediate action and delaying the recovery of spilled oil.

The inventor of the present invention has conducted extensive research in order to overcome the drawbacks of the conventional fastener connection method and develop an oil fence adapter that can be connected more quickly.

As a result, they discovered that operating time can be significantly shortened by temporarily securing oil fences floating on the sea and then connecting them with fasteners, leading to the completion of the present invention.

The present invention will be explained as follows with reference to the drawings.

That is, as one aspect of the present invention is shown in FIG. The present invention provides an oil fence adapter which is provided with a connecting piece 3 having a fastener, and connecting pieces 4 and 5 having fasteners on the other side and middle part of the adapter main body 1.

When using an oil fence, the adapter of the present invention is connected to both ends of the fence in advance by connecting pieces 3 on the sides to integrate it, and this is extended to the sea when oil leaks.

After extending the required number of oil fences of appropriate lengths, each oil fence is connected by the adapter of the present invention attached to the end.

The adapter of the present invention can be conceived in various forms.

The connection piece 3 on one side of the adapter body 1 is necessary because it is connected to the oil fence in advance as described above, but the connection piece 4 on the other side and the middle part It is preferable to provide the connecting pieces 5 together.

Furthermore, the installation direction of these connecting pieces 3, 4.5 is such that the connecting pieces 3 and 4, 5 protrude on the opposite side with respect to the surface of the adapter body 1, as shown in FIG. It is preferable to provide this, and by doing so, it becomes possible to connect oil booms continuously using adapters of the same type.

Furthermore, the floating body 2 installed on the top of the adapter main body 1 is equipped with a tension belt 7, which is used to tie and temporarily fasten the adapters attached to each oil fence to be connected. The purpose is to bring them close to each other to facilitate connection with the fastener and to reinforce the tensile strength of the fastener connection portion.

In addition, in the adapter of the present invention, the floating body 2 can be equipped with a temporary fixing locking ring 6 together with the tension belt 7, and by using this, the oil fence to be connected can be temporarily fixed with a single touch. .

In addition, the tension belt 7 and the temporary locking ring 6 may be installed at any position on the floating body 2;
Considering the convenience of temporary fixing operation, the part that rises above the sea surface when the adapter is floated on the sea, that is, the floating body 2
It is preferable to use the upper surface of the .

Further, the mutual positional relationship between the connecting piece 5 provided in the middle part of the adapter main body 1, the tension belt 7 provided on the floating body 2, and the temporary locking ring 6 is not particularly limited and is shown in FIG. Even if the positional relationship is such that the temporary locking ring 6 is installed between the connecting piece 5 and the tension belt 7, the connecting piece 5 is also placed between the tension belt 7 and the temporary locking ring 6. Alternatively, the tension belt 7 may be placed between the connecting piece 5 and the temporary locking ring 6.

In other words, all of the three considered positional relationships described above can be forms of the adapter of the present invention.

Next, the first embodiment, which is a preferred embodiment of the adapter of the present invention, is explained.
The usage of the adapter will be explained in sequence based on the adapter shown in the figure.

First, before deploying the boom out to sea, attach this adapter to the tip of the boom to be connected (see Figure 2).

Next, after deploying the oil fence with the adapter attached to the sea, connect the two oil fences to be connected as shown in Figure 3A.
The temporary locking rings 6 installed on the adapter at the tip of the oil fence are locked together with a single touch using a rope 8 with a carabiner 9 (see Fig. 4) to remove the oil. Figure 3B
Tighten it temporarily like this.

However, this temporary fixing cannot sufficiently suppress the mutual movement of the two oil fences, so the tension belts 7 installed on the adapter are further connected to the shackle 1.
1 (see FIGS. 5 and 6), and keep the oil booms in close proximity to each other (see FIG. 3C).

After that, the oil fence is completely connected using the fastener 4 or the fastener 5.

Here, the fastener connection can be made by using the fastener 4 under normal conditions, but it can be easily connected by using the fastener 5 when the fastener 4 is damaged or when weather conditions worsen.

As mentioned above, according to the adapter of the present invention, the oil fences floating on the sea are temporarily fastened to each other and then completely connected using the fasteners, so the connection progresses extremely smoothly and it is possible to connect the booms in an emergency. Extremely effective for extending and connecting oil fences.

Moreover, even when weather conditions worsen, there is no need to pull up the oil fence connection part on board and operate it, and the dipper can directly perform the connection work, which hardly hinders the progress of the connection work and prevents the spread of oil leakage damage. can be effectively prevented.

In addition, when spilled oil surrounded by an oil fence connected with the adapter of the present invention is forcibly led out of the oil fence and collected, first fastener 4 or 5 is used.
, then replace the rope 10 with the shackle 11 that connects the tension belts 7 to each other with a longer one, and then remove the rope 8 with the carabiner 9 (7th
(see figure).

When stopping the oil recovery work outside the oil fence, the oil fences may be connected to each other again using the same procedure as described above.

In addition, when a recovery vessel enters the oil fence to recover spilled oil, the adapter of this invention allows the oil fence to be connected easily and quickly, allowing the oil fence to be disconnected. Even if a recovery ship is brought in, the leakage of oil outside the boom can be minimized.

Next, an example using the adapter of the present invention will be shown.

Example tidal current approximately 0.5 knots/hour, wind speed 7 m/sec, wave height approximately 0
．． An oil fence 7 with a floating body diameter of 55Q mm, a length below the sea surface of 75Q mm, and a weight of approximately 10 kg/m at a sea depth of 5 m.
00m and 600m using the adapter of this invention as shown in Figure 1, it took about 5 minutes, and it took about 5 minutes compared to the conventional adapter (fastener 5. temporary locking ring). 6 and one without tension belt 7), the working time was significantly shortened compared to the approximately 20 minutes required when the oil boom was hoisted onto a work boat with a crane.
