Hereinafter, it is assumed that the lifeboat 5 is provided on the ship 1, but it goes without saying that the same technique may be applied to an offshore structure such as an offshore plant or an FPSO in addition to the ship 1.

The life boat launch device 10 according to an embodiment of the present invention includes a frame 11, a swash plate 12, a canister 13, and an air mat 14. [

The frame 11 is provided on the side or stern side of the ship 1 and has a structure capable of storing or storing the lifeboat 5 normally.

A swash plate (12) having a predetermined inclination angle is provided at the center of the frame (11) so as to face the outside of the ship (1). The lifeboat 5 is seated on the upper surface of the swash plate 12. [

(Not shown) for preventing the normally lifeboat 5 from sliding on the swash plate 12 may be protruded in front of the seating point of the lifeboat 5. [ The lifting plate 5 is prevented from being lifted up by the lifting plate 5 when the lifting height of the lifting lane 5 is changed by inserting the lifting plate 5 into the swash plate 12 or by inclining the slashing plate 12 in parallel with the slashing plate 12, The swash plate 12 can be slidably moved on the swash plate 12.

Or grip means (not shown) for normally holding the lifeboat 5 may be provided behind the seat. The grip means can remove the pulling force on the lifeboat 5 by releasing the grip on the lifeboat 5 so that the lifeboat 5 can slide on the swash plate 12 by its own weight have.

A guide rail (not shown) for guiding the sliding movement of the lifeboat 5 may be provided on the swash plate 12. In this case, the lifeboat 5 can be safely slidably moved in the lateral side direction of the ship 1 along the guide rail even in a state where the ship 1 is tilted toward the forward or stern side in an emergency.

A canister (13) may be hingedly connected to the lower end of the swash plate (12).

Referring to FIG. 2, the canister 13 includes a hemispherical first body 21 and a second body 22, which are hollow spheres by engagement.

The first body 21 is connected to the lower end of the swing plate 12 through the hinge 30 and the second body 22 is hinged at the lowest point of the opening of the first body 21 I have.

The canister 13 is normally coupled such that the open face of the first body 21 and the open face of the second body 22 meet with each other. The engagement of the first body 21 and the second body 22 can be released by an operation of the lifeboat occupant in an emergency.

For example, the first body 21 and the second body 22 may be held in a coupled state by a safety pin (not shown) fixed around the opening. In this case, the safety pin is connected to the safety pin. When the safety pin is removed by pulling the rope by the occupant of the lifeboat, the first body 21 and the second body 22 are disengaged from each other, Space can be opened.

Alternatively, the first body 21 and the second body 22 can be maintained or released in a coupled state by separate driving means (not shown). That is, the driving means is operated so that the opening face of the first body 21 and the opening face of the second body 22 meet each other at normal times, and in the event of an emergency, The driving means can be operated so that the open sides of the two bodies 22 are separated from each other.

The canister 13 receives the compressed air mat 14 in its internal space in the engaged state.

The air mat 14 is normally compressed and has a minimum volume and is compressed. In an emergency, the valve of the compressed air tank for opening the air mat is opened, and the compressed air is injected into the air mat 14, (14) expands and unfolds toward the sea level.

Here, the compressed air tank can be installed in the canister 13 and can be integrated with the canister 13. Or the compressed air tank may be provided outside the canister 13 and a high pressure hose (not shown) may be connected to the air mat 14 in the canister 13.

The upper end of the air mat 14, which is completely opened, is coupled to the first body 21 of the canister 13. Since the first body 21 is connected to the outlet side of the swash plate 12 by the hinge 30, the air mat 14 can be always sloped on the sea surface irrespective of the height of the sea surface.

The lifeboat 5 injected from the swash plate 12 is slid along the air mat 14 and gets off the lower end.

The shape and / or length of the air mat 14 may vary depending on the shape of the lifeboat 5, the installation position in the vessel 1, and the like.

The air mat (14) may have a bent shape so that the lower end of the air mat (14) has a predetermined inclination angle when compared with the central portion in the inflated state in order to reduce the impact upon the arrival of the lifeboat (5). In this case, the lower end of the air mat 14 in the inflated state is parallel to the sea surface or has a very small inclination angle, so that the intake angle of the lifeboat 5 is reduced, thereby widening the water intake area and reducing the intake shock.

Further, the air mat 14 may have a length such that at least the lower end of the air mat 14 can reach the sea surface in the expanded state.

3, assuming a water line in a state in which no cargo is loaded on the ship 1, the distance H between the outlet side of the swash plate 12 and the water line and the inclination angle? Of the swash plate 12, The length L of the air mat 14 can be determined.

In order to make the inclination angle of the air mat 14 less than the inclination angle of the swash plate 12, the length L _min of the air mat 14 when the inclination angle of the air mat 14 is equal to the inclination angle of the swash plate 12 You can increase the length.

Therefore, the length of the air mat 14 can be determined according to the following equation (1).

The inclination angle of the air mat 14 is equal to or smaller than the inclination angle? Of the swash plate 12 when the air mat 14 is inflated. In this case, the lifesaving boat 5 injected from the swash plate 12 is slid smoothly in the air mat 14, so that the impact upon arrival can be further reduced.

However, since the angle of inclination of the air mat 14 with the sea surface is small due to the immersion degree or inclination of the ship 1, the lifeboat 5 which is out of the swash plate 12 is placed on the air mat 14 and escapes on the sea surface It may not be possible.

In this case, the air mat (14) is opened by a certain amount of time after the air mat (14) is unfolded by the expansion, so that the air in the air mat (14) .

Or the pushing lever 60 may be further provided as a means for causing the inner line bottom surface 50 of the lifeboat 5 to lose the buoyancy of the air mat 14. [

Referring to FIG. 4, the pushing lever 60 includes a pointed end portion 64 having a sharp tip. The pushing lever 60 has a structure in which the stopper portion 62 is resiliently supported by the spring 70 so that the tip end portion 64 is located in the storage groove 55 formed in the line bottom surface 50 and is not exposed to the outside of the bottom have.

When an external force is applied to the pushing lever 60 in a downward direction, the spring 70 is compressed and the tip portion 64 positioned in the storage groove 55 protrudes from the bottom of the bottom of the air mat 14, It is possible to make a hole in the upper surface of the air mat 14 so as to lose the buoyancy.

When the air mat 14 loses its buoyancy, the lifeboat 5 placed on the air mat 14 can be slowly obtained and can be advanced.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
