[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting an oil fence on a revetment or the like where there is no oil leakage and the extension length can be easily adjusted.

[0002]

2. Description of the Related Art When unloading oil while berthing a tanker or the like on a shore, it is necessary to turn an oil fence around the tanker to prevent oil from spreading when it leaks to the water surface. ing. Therefore, mounting of the conventional oil fence on a seawall, etc. is performed by a plan view of FIG.
As shown in the side view, the extension length of the oil fence 3 is adjusted by tying the oil fence 3 with a rope 4 to a float 5 placed in a cylindrical casing pipe 2 provided on a seawall 1 or the like. Was.

[0003] This mounting method is for enabling the float 5 to follow a change in the tide level of the water surface W. In this case, a gap indicated by an arrow S between the oil fence 3 and the revetment 1 is provided. This causes a problem that oil leakage occurs.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and has no oil leakage and is easy to adjust the length of extension to a revetment of an oil fence. It is intended to provide a mounting device.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, the device for mounting the oil fence of the present invention to a seawall, etc., is mounted on a float in a casing fixed to the seawall, etc.
An overhanging member having a T-shaped cross section is provided so as to protrude from the casing, and an oil fence fixing member which can be opened and closed by a hinge is provided at an end of the overhanging member. The upper end of the member is provided on a member that can be opened or fixed, or a half-split casing that can be opened and closed with a hinge provided at the lower end as a fulcrum is fixed to a seawall, etc., and the upper end of the half-split casing is opened or fixed. It is constituted by providing a possible member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan sectional view of a first embodiment of a device for mounting an oil fence on a seawall, etc. FIG. FIG. 1 is a side sectional view taken along the line AA of FIG. First, as shown in FIG. 1 and FIG. 2, a T-shaped cross-section projecting member 6 is attached to a float 5 contained in a casing 2 which is a cylindrical guide fixed to the revetment 1 and the like. It is provided to protrude.

Next, an oil fence fixing member 8 which can be opened and closed by a hinge 7 is provided at the lower end of the projecting member 6 having a T-shaped cross section.
However, as the oil fence fixing member 8, a member in which two round steel bars are parallel as in this embodiment, or a plate can be used. And the screw member 9 which can fix or open the upper end of the projecting member 6 of a T-shaped cross section and the upper end of the oil fence fixing member 8 is provided.

In order to prevent the oil fence 3 from being damaged, the oil fence 3 of the projecting member 6 having a T-shaped cross section is used.
It is preferable to provide a protective material such as a sheet on the surface in contact with. In order to attach the oil fence 3 to the revetment 1 or the like using the attachment device of the present invention having the above configuration,
First, the screw member 9 is loosened, and the oil fence fixing member 8 is opened.

Next, the oil fence fixing member 8 is closed with the float-free portion of the oil fence 3 extended to a predetermined length in contact with the overhanging member 6, and the oil fence 3 is fixed to the oil fence fixing member 8. The screw member 9 is fastened and fixed between the members. In this embodiment, a slight gap may be formed between the casing 2 and the float 5. However, when the oil fence 3 is extended, the float of the oil fence 3 moves in a certain direction due to wind or waves. However, there is no problem since this gap is always closed. In addition, when the float 5 and a member connected to the float 5 are provided on the upper surface of the float 5 with a rope hook 17 for lifting and lowering the float 5, attachment and detachment in the casing is easy.

Next, FIG. 3 is a plan sectional view of a second embodiment of a device for mounting an oil fence on a seawall, etc. of the present invention.
4 is a side view of FIG. 3, and FIG. 5 is an enlarged view of a portion A in FIG. First, as shown in FIGS. 3 and 4, a half-split casing 10 in which a steel pipe casing is split in half is fixed to the revetment 1 or the like with anchor bolts 9 or the like. The half-split casing 10 is provided at the lower end. It has a structure that can be opened and closed with the hinge 11 as a fulcrum.

The half-break casing 10 is provided with an overturn prevention member 12 at its lower portion in order to prevent the casing 10 from opening excessively. Next, a fixing cap 13 for fixing each half-split casing 10 is detachably provided at the upper end of the half-split casing 10. In order to prevent damage to the oil fence 3, each half-split casing 10
It is preferable to provide a protective material 14 such as rubber on the surface of the half-split portion that contacts the oil fence.

When the oil fence is mounted on the revetment 1 using the mounting device of the present invention having the above configuration, first,
The fixing cap 13 is removed, the half-split casing 10 is opened with the hinge 11 as a fulcrum, and the portion of the oil fence 3 that has been stretched to a predetermined length without a float is inserted into the inside of the half-split casing 10. The casing 10 is closed and the upper end is covered with the fixing cap 13 to fix the divided upper end of the half-split casing 10.

In the present invention, a slight gap is formed between the half-split casing 10 and the oil fence 3, but when the oil fence 3 is extended, the oil fence 3
This gap is closed because the float moves in a certain direction due to wind and waves, so there is no problem. Then, as shown in FIG. 5, a protection member 14 such as rubber is attached to the casing 10 by bolts 16, and a pressing member 15 such as a rubber plate is protruded from the casing so as to press the oil fence from both sides. The gap between the oil fence 3 and the casing 10 can be filled.

[0014]

[Effect of the Invention] According to the above-described device for mounting an oil fence on a seawall, etc. of the present invention, the oil fence can be easily mounted on the seawall with a desired extension length, and oil leakage can be reduced. It can be completely prevented and has a simple structure in which the fence is sandwiched by a half-split casing made of steel pipe etc., which has the advantage of low production cost and easy installation work of the oil fence. .
