Description

[Detailed description of the invention] The present invention relates to a capsized boat crew rescue device.

In recent years, the number of marine accidents has been increasing rapidly, and rescuing the victims has become a major problem.

In particular, rescue of survivors trapped inside a capsized ship is carried out by opening the belly of the ship, but in this case, the air inside the ship may escape through the opening and the capsized ship may capsize or sink even further, so rescue of survivors is difficult. The reality is that it is extremely difficult not only to carry out activities, but also to prevent capsized ships from sinking.

The present invention solves the above problems and provides a method and apparatus that can rescue survivors trapped inside a capsized ship without sinking the capsized ship.

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is a rescue capsule with an airtight structure;
It consists of a spherical upper capsule 2 and a cylindrical lower capsule 3.

The upper capsule 2 is for accommodating a passenger, and a scaffold 4 is fixed to its inner lower part, and a grip ring 6 is suspended from the center of its inner upper part via a hanging rod 5.

The upper capsule 2 further includes a passenger entrance 7 and a door 8 on its side, a hanging fitting 9 on its outer upper part, and a pressure equalizing valve 10 at an arbitrary position.

The lower capsule 3 is provided with an occupant rescue opening 12 and a lid 13 at its bottom 11.

The lid 13 is disposed inside the capsule, and is attached so as to be rotatable in the vertical direction via a link 16 so that the lid 13 can properly abut the mouth periphery 15 at the seal member 14 on the lower periphery.

A threaded rod 19 having a handle 17 at its upper end and a locking plate 18 at its lower end is screwed into the center of the lid 13.

The lock plate 18 is rotatably fitted onto the threaded rod 19 and is supported by a collar 20 provided at the end of the threaded rod 19 as shown in FIG. The collar 2G is biased by a compression spring 22.

For the lock plate 18, as shown in FIG.
The two notches 23a and 23b through which both ends of the lock plate 18 can pass in the vertical direction, and the lower end of the mouth peripheral edge 15 and a position spaced approximately 90 degrees from the side of the notch 23a are used to lock the lock plate 18. A pair of stoppers 24a and 24b are provided to restrict rotation of the plate 18.

Of course, the sealing member 14 of the lid 13 is provided so as to come into contact with the mouth peripheral edge 15 on the outside of the notches 23a, 23b, as shown in FIG.

Reference numeral 25 denotes a connecting device that integrally connects the upper capsule 2 and the lower capsule 3 at their mutually contacting inner flanges 26 and 27.

The coupling device 25 is provided at multiple locations in the circumferential direction, and includes a hook 29 that engages with the flange 27 of the lower capsule 3 at an engaging piece 28 at the lower end, and a hook 29 that is rotatably and slidably supported by the upper capsule 2. It consists of a bracket 30 and a handle 31 screwed onto the hook 29 on the bracket 30.

As shown in FIG. 4, the flange 27 of the lower capsule 3 has a hook 29 at its hook engaging portion in the handle tightening direction.
A anti-rotation piece 32 is provided to prevent the rotation of the rotor from rotating together.

Reference numeral 33 denotes a ring-shaped magnet, which is provided at the lower end of the lower capsule 3 and outside the passenger rescue port 12 concentrically therewith.

34 is a magnet holder, and 35 is the belly of the capsized ship.

Next, the rescue method will be explained.

First, rescue workers are taken into the rescue capsule 1 through the crew entrance/exit 7.
After boarding the capsule 1, the capsule 1 is lowered onto the belly 35 of the capsized ship by a suspension device (not shown) such as a rescue tender or a helicopter.

At this time, the capsule 1 is attracted to the hull 35 by the magnet 35, and the sliding movement of the capsule 1 is prevented from the shaking of the capsized ship due to the waves.

Next, open the occupant rescue port 12 at the bottom.

This allows the rescuer to release the tightening force on the threaded rod 19 by rotating the handle 17, and with this release, the lock plate 18 rotates together with the threaded rod 19 due to the elastic force of the compression spring 22, causing the stopper 24a to rotate. It is sufficient to lift the lid 13 in a state where it is received by the lock plate 18, that is, with the lock plate 18 aligned with the notches 23a and 23b.

Next, the capsule 3 is integrally and airtightly fixed to the hull 35 at its inner periphery by welding.

This is because the air inside a capsized ship is usually compressed by the weight of the ship and has a slightly higher pressure than the outside air pressure, so when the bottom opens, a huge amount of pressure is applied to the capsule and the holding power of the magnets alone is not enough. (For example, if there is a difference in internal and external pressure of 0.1 kg/cm2 and the cross-sectional area of capsule 3 is 1 m2, the force in the direction of pushing capsule 3 away from the bottom of the ship is 1 to
This is done to ensure that the capsule is securely secured to the bottom of the ship, as it is necessary to maintain airtightness, and to protect against the shaking of the capsized ship during waves, wave pressure on the capsule due to waves, etc.

Of course, if there are few waves, the above welding is not necessary.

Then, a drill hole (not shown) is made in the hull 35 to equalize the pressure inside the capsule with the inside of the capsized ship.

Thereafter, a hole 36 is made in the hull 35 from the crew rescue port 12 inside the capsule using a gas cutter or the like, and the crew members inside the capsized ship are pulled up through the hole 36 and accommodated in the upper capsule 2.

Once the crew has been accommodated, cover the lid 13 and open the hole 3 in the hull 35.
Close 6.

This lid is intended to keep the capsized ship airtight even after the capsule has left the bottom of the ship. Normally, the fatigued crew members of the capsized ship are transported to the mother ship or land base as soon as possible after being placed in the capsule. In addition, it is possible that the capsized ship is filled with flammable gas due to damage or leakage in the oil tank of the capsized ship.
This design was designed to prevent the use of firearms for airtight processing after rescue.

After the lid 13 is brought into contact with the mouth peripheral portion 15 and the lock plate 18 is passed through the notches 23a and 23b, the threaded rod 19 may be rotated.

The lid 13 is fixed by tightening the lock plate 18 with the threaded rod 19 from the time when the lock plate 18 hits the stopper 24b.

Next, because the pressure inside the capsule is equalized with that inside the capsized ship,
Since the pressure is higher than the outside air, it is difficult to rotate the handle 31 by input when separating the capsules 2 and 3, and even if it is possible to rotate the handle 31, the engaging piece 28 does not touch the capsule 3.
In order to prevent the capsule 2 from being blown away, the pressure equalizing valve 10 is opened to equalize the pressure inside the capsule with the outside.

Next, turn the handle 31 of the coupling device 25 to release the hook 29.
is loosened, and the engaging piece 28 is reversed to disconnect the upper capsule 2 and the lower capsule 3.

Next, the upper capsule 2 is lifted up as shown in Fig. 5 and transported to the desired location, and after this transport, the door 8 is opened and the occupants are rescued.

At this time, the air inside the capsized ship is prevented from escaping outside the ship by the lid 13 on the hull 35.

As explained above, the present invention enables even if a hole is made in the belly of a capsized boat when rescuing a crew member trapped inside a capsized boat,
The airtight structure of the rescue capsule prevents the air inside the capsized ship from escaping, allowing crew members to be rescued safely.

In addition, even after the crew is accommodated in the upper capsule and the upper capsule is lifted and recovered, the hole in the belly of the ship is closed by the lower capsule, which prevents the capsized ship from sinking and allows it to be recovered. can.
