Description

Oil fence {Oil-fence}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil fence, and more particularly, to an oil fence for preventing oil spreading and marine pollution in the event of an oil spill due to collision of an oil tanker at sea or stranding.

Since the ship is driven by the power of the engine engine, there is an oil tank for storing and supplying the fuel. When such a ship hits the reef or collides with another ship, the oil tank is broken, The leak occurs. These oil spills are causing serious problems, such as polluting the oceans, destroying the marine ecosystem, depleting offshore resources and ending fish farming.

Particularly, in the case of a large-sized ship, an oil tanker, etc., the above-mentioned problems become more serious.

In order to reduce such marine pollution, the oil fence is installed to suppress the spread of oil, and the oil is decomposed by the emulsifier to precipitate.

As an example of a conventional oil fence, a public utility model No. 20-1998-015488 is disclosed.

In the conventional utility modeling technique, a cylindrical tube is formed on the upper part, a ground portion is formed at the center of the lower surface of the cylindrical tube to attach a weight, iron pieces and a magnetic body are formed at both ends, So as to prevent the spread of oil.

However, even when a large amount of oil flows out, there is a limitation in suppressing the diffusion of oil. In particular, even if the weight of the oil fence is provided, the cylindrical tube can be freely pivoted and rotated, In addition, the oil is easily moved to the outside beyond the oil fence by the waves, and the diffusion of the oil can not be effectively prevented.

In addition, the conventional oil fence is installed on the sea, but the ship can not easily approach the oil fence. Therefore, when the oil fence is damaged or damaged, or when a part of the oil fence is not properly deployed, , It is difficult for an operator to cope with an oil spill due to the structure that the operator can not move over the oil fence.

FIG. 6 is a view showing a fence plate which is lifted up from a fence fixing plate according to the rise of a wave according to the present invention. FIG. 7 is a state in which a tread plate is installed on the upper part of the oil shut-off tube according to the present invention, and FIG. 8 is a state of use of the oil fence according to the present invention.

As shown in FIGS. 1 to 8, the oil fence according to the present invention is installed on both sides of an outer wall of a ship and is installed on the sea. When the oil outflow occurs according to the pier of a ship, Thereby preventing the oil from spreading to the sea.

In particular, since the oil fence of the present invention has air spaces formed on both sides of the water receiving space, the oil fence of the present invention can be formed with a relatively large width as compared with the conventional oil fence, The oil shut-off tube is provided on the upper part of the oil shut-off tube so that the worker can move over the step and can take an effective follow-up action.

Specifically, the oil fence of the present invention includes a fence fixing plate 20, a fence coupling plate 30, and an oil shut-off tube 40.

The fence fixing plate 20 is formed as a plate having a predetermined area, and is installed so that one side thereof is attached to the fore and aft side walls of the ship 10, respectively.

The attachment structure of the fence fixing plate 20 may be integrally welded to an outer wall of the ship. A magnetic member 25 is coupled to the fence fixing plate so that the fence fixing plate 20 can be detached and attached. It can be attached to the outer wall of the ship.

When attaching the fence fixing plate by the magnetic body, the magnetic body preferably uses a neodymium magnet having a strong magnetic force. Since the fence fixing plate may be separated by external pressure such as waves, the magnetic force of the usable magnetic body should be calculated something to do.

The fence coupling plate 30 is coupled to the pair of fence fixing plates 20 so as to be vertically displaceable by the position shifting means and has an air supply portion 31 and a water supply portion 32 formed on one side thereof .

The fence coupling plate 30 may be formed to have the same or similar area as that of the fence fixing plate 20 or to have an area smaller than that of the fence fixing plate 30, And the oil shut-off tube 40 should be coupled to the edge of the other surface.

The oil shut-off tube 40 is integrally formed at both ends of the fence coupling plate 30. The cross-sectional structure of the oil shut-off tube 40 includes a plurality of air spaces 41 filled with air, And a water receiving space 42 formed for the center of gravity and filled with water.

The air space 41 is formed in a number corresponding to the number of the air supply units 31 and is partitioned from each other. Preferably, the air space 41 is located at the center of the water storage space 42, One on each side of the accommodating space, and one air space including the water accommodating space is formed on the upper side thereof.

That is, the air space 41 includes left and right air spaces 41a formed in the right and left sides of the water receiving space 42 at the center of the water receiving space 42 and left and right air spaces 41a, And an upper air space 41b formed to cover the left and right air spaces 41a and the water accommodation space 42 on the upper side of the water accommodation space 42. [

Accordingly, the oil containment tube can be centered by the water contained in the water receiving space 42, and the oil cut-off tube can protrude from the sea level at a certain height due to the formation of the air space at the upper side.

Here, as shown in FIG. 4, each of the air spaces 41 is formed to be connected to the air supply unit so that air can be supplied smoothly.

At this time, the water receiving space 42 itself is formed to protrude longer than the bottom height of the left and right air spaces 41a. The reason is as follows: First, when water is contained in a water receiving space, the oil shut-off tube can accurately catch the center of gravity even when an external pressure such as a wave occurs, so that it is stably installed and can not be easily conducted. Second, The flow of the water in the water receiving space is prevented as much as possible so that the movement of the oil can be blocked by the water receiving space.

An air supply pump 50 is connected to the air supply unit 31 and a water supply pump 51 is connected to the water supply unit 32. The air supply unit 31 corresponds to the number of air spaces The air supply pump 50 may be connected to the air supply pump 50 in a one-to-one or multi-stage manner.

In the meantime, according to the oil shut-off tube 40 of the present invention, the oil shut-off tube 40 also has a different height due to the wave of the waves. At this time, a space with the sea surface is formed at the joint part of the outer wall of the ship, May occur.

Therefore, in order to block the oil shut-off tube, the fence coupling plate 30 integrally formed with the oil shut-off tube can be coupled to the fence fixing plate 20 so as to be movable up and down.

For this purpose, a position shifting means is provided between the fence fixing plate 20 and the fence engaging plate 30, and the fence engaging plate 30 is coupled to the fence fixing plate 20 through the position shifting means, It will be done.

2, the position shifting means includes a guide groove 21 formed on the other surface of the fence fixing plate 20 in a vertical direction so as to extend from the upper end portion to a lower portion of the fence fixing plate 20, And a moving protrusion 35 vertically formed in a shape corresponding to the guide groove 21 so as to be vertically moved on the guide groove 21 by being inserted into the guide groove 21 from the upper side of the fence fixing plate 20 .

In this case, there is a possibility that the fence-engaging plate 30 is separated from the fence-fixing plate 20 while rising too much in the upward direction. In order to prevent this possibility of separation, The upper end of the guide groove 21 is covered with a separate cover means 22 so that the movement protrusion is prevented from being separated from the upper end of the guide groove.

The guide groove 21 and the moving protrusion 35 may be structured so as to be slidable upward and downward without being separated from each other, so that the detailed coupling structure can be any structure.

Meanwhile, as shown in FIG. 7, a tread plate 60 is installed on the upper side of the upper air space 41b. The reason why the tread plate 60 is provided is to cover the upper part of the oil shut-off tube 40 so that an operator can move over the foot. In addition, since the tread plate is installed, .

The oil fence of the present invention may be provided so as to be connected to fore and aft ends of a ship, or may be connected to a fore and aft end of a ship after two or more oil fences are combined with each other.

When two or more oil spouts are installed, the intermediate connection part can be conveniently used by being connected to the collection vessel or the collection device of the spilled oil.

In the process of installing the oil fence constructed as described above, if the outflow of oil from the ship is first confirmed, a fence fixing plate is immediately attached to the outer side wall of the ship (oil tanker), or if the oil fence is already welded and attached, The guide groove 21 is engaged with the movement protrusion 35 formed on the fence coupling plate on one side of the oil shut-off tube.

Then, a transfer protrusion formed on the other fence coupling plate of the oil shut-off tube is inserted into the guide groove of the fence fixing plate attached to the outer wall of the stern at the stern outer wall of the ship (oil tanker).

Thereafter, the supply hose of the air supply pump 50 is connected to the air supply unit 31, the supply hose of the water supply pump 51 is connected to the water supply unit 32, and the air supply pump and the water supply pump are operated And supplies air and water to the air supply unit and the water supply unit, respectively.

The air and water supplied through the air supply unit and the water supply unit are installed in the air space and the water receiving space and are tightly extended to the sea surface while being tightly extended with the oil shut-off tube, and the oil leaked together with the oil shut- .

6, when the oil shut-off tube is raised or lowered due to a wave or the like, the fence engaging plate 30 is moved up or down on the fence fixing plate 20 to block the space between the oil interception tube and the sea surface So that the possibility of leakage of the oil can be blocked.

On the other hand, since the left and right air spaces are formed on the right and left sides of the water receiving space, the center of gravity of the oil shut-off tube is precisely caught by the water filled in the water receiving space, and the water receiving space is longer Extruding into the ocean further reduces oil movement by waves and currents.

As described above, the present invention improves the structural problems of the conventional oil fence and makes it possible to install the oil fence immediately within a short time, thereby enabling immediate measures to be taken when an oil spill occurs.
