Description

[Detailed explanation of the idea] The present invention relates to a connecting device for a floating oil dike.

Floating oil embankments surround floating oil that has leaked onto the water surface and prevent its spread. What is important is how to configure the connection mechanism.

Typical examples of conventional coupling devices are shown in FIGS. 1 and 2.

Figure 1 is its plan view, and Figure 2 is from ■-■ in Figure 1.
FIG.

A cylindrical slide guide 3 having a slit 2 on the opposite side is attached to a quay wall or dolphin 1 as a fixed structure, and a buoyant body 5 having a connecting fitting 4 is moved up and down freely in this slide guide 3. The oil fence 6 is connected via the connecting fitting 4.

The oil fence 6 is protected from the floating body 7 and the oil-proof plate 8.

This conventional floating oil dike connection mechanism had the following drawbacks.

(1) As the oil fence 6 becomes larger and the tension acting on the connecting portion increases, the frictional force between the slide guide 3 and the buoyant body 5 increases, significantly inhibiting the vertical movement of the buoyant body 5,
There is a risk of oil leakage.

Furthermore, in response to the increase in frictional force, the slide guide 3 and the floating body 5 are also made larger, which is not economical.

(2) In the case of a floating oil fence that is large and made of a material with high rigidity such as steel, the effects of shaking of the oil fence 6 due to waves or the like will be concentrated on the connecting portions, and there is a risk that the connecting mechanism may be damaged.

The present invention was developed in view of the above circumstances, and its purpose is to provide a connecting device for a floating oil dike that allows for movement of the floating oil dike while improving oil prevention performance at the connecting portion. do.

Therefore, the floating oil dike connection device of the present invention is a device for connecting a floating oil dike body and a fixed structure such as a quay or a dolphin, or between floating oil dike bodies. It is characterized in that deformable comb-like flexible fins are provided on opposing surfaces of the body, and the fins are configured to mesh with each other.

A connecting device for a floating oil dike according to a first embodiment of the present invention will be explained below with reference to the drawings. FIG. 3 is a plan view thereof, and FIG. 4 is a side view thereof.

9 is a quay wall as a fixed structure, 10 is a comb-shaped quay side flexible fin made of an elastic material such as rubber attached to the quay wall 9, and 12 is a floating oil barrier body (hereinafter referred to as a floating oil barrier). ) 11, a comb-shaped oil barrier side flexible fin 13, which is almost the same as the quay side flexible fin 10, is attached to the end near the quay wall 9 via an end plate 14, and the quay side flexible fin 10 and the oil barrier side flexible fin 13 are designed to mesh with each other.

15 and 16 are oil-proof plates provided at the upper and lower parts of the floating body 12, respectively.

A chain 17 connects the quay 9 and the floating oil barrier 11, and its length is adjusted so that the quay side flexible fins 10 and the oil barrier side flexible fins 13 do not deviate from their engagement.

FIG. 5 shows a state in which the floating oil barrier 11 connected in this manner is moving due to waves or the like.

The quay side flexible fins 10 and the oil barrier side flexible fins 13 are made of an elastic body such as a comb.
The floating oil barrier 11 deforms as shown in this figure in response to lateral movement (side-to-side rocking, rolling, bow rocking).

In addition, if the floating oil barrier 11 undergoes longitudinal movement (back-and-forth rocking, up-and-down rocking, vertical rocking), the quay-side flexible fin 1
0 and the oil barrier side flexible fin 13 slide against each other.

The quay side flexible fins 10 and the oil barrier side flexible fins 13 are comb-shaped and are arranged so as to mesh with each other, so in most cases, as shown in FIG. 10.13 is in close contact.

Further, even if this close contact is not perfect, the gap is extremely small.

Therefore, the following effects can be obtained.

(2) The comb-shaped flexible fins 10.13 are in close contact with each other, or even if the contact is not perfect, the gap between them is extremely small.

Therefore, the amount of oil that is about to flow out becomes extremely small as it weaves through the gaps between the comb-like flexible fins 10 and 13, and the oil that flows out from the oil reservoir side to the outside of the oil barrier is absorbed by the multi-stage flexible fins 10 and 13. 13.

■ It allows large vertical displacements due to the tide level and movement of the floating oil barrier 11 due to waves, etc., and maintains the oil barrier function even under such conditions.

■ There may be cases where the floating oil barrier 11 collides with the quay 9 due to waves, etc., but in that case, the flexible fin 1
0.13 acts as a shock absorber to alleviate the collision force and prevent damage to the floating oil barrier 11.

The connection between the floating oil barrier 11 and the quay wall 9 has been described above. Next, the connection between the floating oil barrier 11 will be described as a second embodiment.

FIG. 6 is a plan view, and FIG. 7 is a side view.

18.19 is a floating oil embankment, and 20.21 is a comb-like flexible fin made of an elastic material such as rubber that is attached to the connecting part of the floating oil embankment 18.19 so that it meshes with each other. It has become.

22.23 is a floating body forming a floating oil barrier 18.19, 2
4.25 is an oil-proof plate provided on the upper part of the floating body 22.23, and 26.27 is an oil-proof plate provided on the lower part.

28 is a chain connecting the floating oil barriers 18 and 19, and its length is adjusted so that the flexible fins 20 and 21 do not lose their engagement with each other.

FIG. 8 shows a state in which the floating oil barriers 18 and 19 connected in this manner are moving due to waves or the like.

The movement of the floating oil embankments 18 and 19 causes relative movements in the vertical, horizontal, longitudinal, and rotational directions at the connecting portion between the two.

Since the flexible fins 20.21 are made of an elastic material such as rubber, they deform as shown in Fig. 8 in response to relative movement of the floating oil barrier 18.19 in the left-right direction and rotational direction. .

Furthermore, when relative movements occur in the vertical and longitudinal directions, the flexible fins 20, 21 slide relative to each other.

The flexible fins 20.21 are comb-shaped and are arranged so as to mesh with each other, so that in most cases the fins 20.21 are in close contact with each other, as shown in FIG.

Furthermore, even if this close contact is not perfect, the gap is extremely small.

Therefore, the following effects can be obtained.

(2) The comb-like flexible fins 20 and 21 are in close contact with each other, or even if the contact is not perfect, the gap between them is extremely small.

Therefore, the amount of oil that is about to flow out becomes extremely small as it weaves through the gaps between the comb-like flexible fins 20 and 21, and the oil that flows out from the oil reservoir side to the outside of the oil barrier is absorbed by the multi-stage flexible fins 20 and 21. , 21.

- Allows movement of the floating oil embankment 18, 19 due to waves, etc., and maintains oil prevention function even if relative movement occurs between the floating oil embankments 18, 19.

■ Floating oil embankment due to movement caused by waves etc.18.19
may collide with each other, in which case the flexible fins 20 and 21 act as a shock absorber,
The collision force is alleviated to prevent damage to the floating oil dike 18 and 19.

As described above, the floating oil dike connection device of the present invention has the advantage of allowing movement of the floating oil dike while improving the oil prevention performance at the connecting portion.
