Description

Sinking ship oil transfer device

The present invention relates to a sunken ship oil transfer device that is attached to the outer hull of a sunken ship and can transfer the oil remaining in the ship after forming a hole.

If a ship that sank due to a maritime accident contains various oils or liquid chemicals in the engine room oil tank, cargo tank, etc., the oil or liquid chemicals on the ship will cause marine pollution even if a very small amount of oil or liquid chemicals leaks into the sea from air vents, etc. It is causing.

In this way, in the event of a ship marine accident, if oil transfer from the sunken ship is not carried out quickly and is delayed in the early stages of the accident, the oil will spread to the coast where nearby beaches, fishing grounds, power plants, water intakes, etc. are scattered, causing a disaster level. Marine pollution occurs and it takes years to decades to clean up.

As an example, there was an intermittent oil leak from the oil tanker Gyeongsin, which sank 35 miles off the coast of Nam-gu, Pohang in 1988, for about 23 years until July 12, 2011, but Korea did not have the technology to remove the remaining oil from the sunken ship. However, the remaining oil in the oil tank was recently recovered.

Accordingly, in the previously disclosed Korean Patent No. 10-1301713, an attachment plate is attached to an adherend with a magnet so as to be watertight by packing, an induction pipe coupled to the attachment plate in a direction perpendicular to the attachment plate, and a blocking valve coupled to the induction pipe. It consists of a drill device that is detachably coupled to a shut-off valve, and the attachment plate, which is attached to the adherend by the magnet, forms a magnet groove on the bottom of the base plate to bury the magnet, and has magnets embedded in it on both sides of the magnet groove. In the residual oil removal device, which also serves as a marine drilling machine, in which a track-type packing groove is formed to internally fix the packing, the device includes: a discharge pipe further installed in a direction perpendicular to the axis of the guide pipe; a blocking valve installed on the discharge pipe; A technology including a pumping device combined with the above-mentioned shutoff valve has been previously registered.

Accordingly, if the airtight pad (10a) is damaged or attached, it can be replaced with an airtight pad (10a) of an appropriate shape and size depending on the condition of the hull surface to which it is attached.

And the outer flange (10b) and the inner flange (10c) are preferably formed of hard material containing stainless steel, iron, or high-strength synthetic resin. This is to prevent the elastic, soft airtight pad 10a from being torn or damaged by hard materials such as screw bolts or tacks.

The transfer body 20 according to the present invention is detachably connected to the first joint portion 13 of the fixed flange portion 10 and is provided at the end to form a transfer passage 21 communicating with the through passage 12. Two joint portions 23 are formed, and a transfer port 24 branched while communicating with the transfer passage 21 is provided on the outer peripheral surface.

As the second joint portion 23 formed on the peripheral surface of the end of the transfer body 20 is coupled to the first joint portion 13 of the fixed flange portion 10, the transfer passage 21 is connected to the surface of the adherend 1. It is arranged and formed to be perpendicular to .

This transfer passage 21 provides a function of guiding the linear movement of the puncture blade 31, which will be described later, and is also a passage that communicates with the pore formed in the adherend 1 by the puncture blade 31 and sucks the transfer fluid. It is used as.

Figure 3 is a longitudinal cross-sectional view showing the internal structure of the sunken ship oil transfer device according to an embodiment of the present invention, the transfer port 24 is formed at two locations on the outer peripheral surface of the transfer body 20, one of which is a pump ( It is connected to P) to suck fluid (oil) into the adherend (1), and the other is provided to insert fresh water supply pipe (W) into the adherend (1) to inject fresh water.

At this time, the transfer port 24 into which the fresh water supply pipe (W) is inserted enters the inside of the adherend (1) through the transfer passage 21 while the fresh water supply pipe (W) is deformed into a gentle curvature as shown in FIG. 3. It is desirable to be formed at an upward inclination angle so that it can be done.

Accordingly, when the transfer screw 34 is rotated, the drive source 33 attached to the installation plate and the drilling blade 31 connected thereto move in a straight line.

The drive source 33 is formed as a motor that rotates by external power including electricity, hydraulics, and pneumatics, and its linear movement is controlled by the transfer screw 34, where one end of the transfer screw 34 is the drive source ( 33) side is connected to the free rotating shaft (34a), and at the other end, a lever (34b) is installed eccentrically to the transfer screw (34).

Accordingly, while the drilling blade 31 is rotated by the drive source 33, the underwater worker turns the lever 34b so that the drilling blade 31 moves toward the adherend 1 to form a hole in the hull, and then After stopping the rotation of the drilling blade (31) and returning it to the upper side of the transfer passage (21), the oil in the hull is transferred through the transfer port.

As described above, the most preferred embodiments of the present invention have been described in the detailed description of the present invention, but various modifications may be made without departing from the technical scope of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above-mentioned embodiments, but should be recognized to the technologies in the patent claims described later and to equivalent technical means from these technologies.

With a single transfer body, the appropriate fixed flange part can be easily replaced depending on the hull material of the sunken ship, so it can be universally used on various types of sunken ships and has excellent industrial applicability.
