BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a diving induction line ejecting apparatus for a sunken vessel.

A ship is a floating structure on the sea and can always be exposed to the risk of sinking. Causes of ship sinking may vary due to collision between vessels, collision with icebergs or reefs, deterioration of marine environment due to bad weather, and engine failure. When the ship sinks, post-rescue operations can be done to rescue the victims trapped in the vessel. However, if the rescue work is delayed for a long time, the survivor may die due to a drop in body temperature or lack of oxygen, and the rescue work needs to be done quickly. During rescue operations, diving lines may be installed extending from the sea level to the sinking vessel so that the diver performing the rescue operation can safely and quickly reach the sinking vessel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a diving-inducing line discharging device of a sinking ship according to an embodiment of the present invention in which a discharge port is closed, and FIG.

1 and 2, a diving guide wire drawing apparatus for a sinking vessel according to an embodiment of the present invention includes a door 100, a receiving unit 200, a buoyancy member 300, a diving guide line 400, And may include an opening / closing unit 500.

The door 100 can open and close the external doorway of the hull 10. Here, the hull 10 may include not only a ship but also a hull of a floating or fixed-type ocean structure, and the outer doorway may be an entrance for connecting the inner space and the outer space of the hull 10 to each other.

The door 100 may be hinged to the hull 10 through a hinge shaft 20. [

The receiving portion 200 may be coupled to or installed outside the hull 10 so as to be adjacent to the external entrance of the hull 10. The receiving portion 200 may be disposed on the upper side of the outer doorway of the hull 10.

The receiving space 200 may be formed with a receiving space 210 and a discharge port 230.

The receiving space 210 is an internal space of the receiving part 200 and can accommodate the buoyant body 300 and the diving induction line 400.

The discharge port 230 is formed to pass through one side of the receiving part 200 exposed to the external space of the hull 10 so that the receiving space 210 and the external space of the hull 10 can be connected to each other.

The receiving portion 200 may be in the form of a hollow rectangular parallelepiped, but is not limited thereto.

The buoyant body 300 may be received in the receiving space 210.

The buoyant body 300 may be an object floating on the sea surface, and the buoyant body 300 may be connected to the diving induction line 400. As a result, when the discharge port 230 is opened, the buoyant body 300 floats to the sea level by the buoyant force so that the diving induction line 400 that guides the diver to the ship 10 can be extended to the sea surface, It is also possible to perform a function as a buoy for indicating the position of the vehicle.

The diving induction line 400 may connect the receiving portion 200 and the buoyancy body 300.

The diving induction line 400 may be formed to have a length sufficient to extend from the hull 10 of the sinking ship to the sea level and may be wound in a receiving space 210 ). &Lt; / RTI >

The outer circumferential surface of the diving induction line 400 may be coated with a luminous material. As a result, the diver can easily return even if it deviates from the diving induction line 400 due to strong current.

The opening and closing part 500 can close the discharge port 230 when the ship is in a normal state and the discharge port 230 is opened when the pressure difference between the accommodation space 210 and the outer space of the hull 10 becomes equal to or larger than a preset value Can be opened. The difference in pressure between the accommodating space 210 serving as a reference for opening the discharge port 230 by the opening and closing part 500 and the external space of the hull 10 is set such that the dive inducing line 400 is installed It may be set assuming the minimum sinking depth of the ship which is needed. The opening and closing part 500 may include a rupture disk. The rupture plate can close the discharge port 230 in normal condition and rupture when the ship sinks and the pressure difference between the accommodation space 210 and the outer space of the hull 10 becomes a predetermined value or more, Can be opened. As a result, a separate mechanical device for opening and closing the discharge port 230 is not required, and installation space and cost efficiency can be increased.

Referring to FIG. 4, the diving-inducing line discharging apparatus of the sinking vessel according to the embodiment of the present invention may further include a door disassembling unit 600.

The door dismantling unit 600 can separate the hinge shaft 20 from the door 100 using the flow of seawater when the seawater flows into the receiving space 210 through the open outlet 230. As a result, the coupling between the hull 10 and the door 100 can be relatively loosened. Accordingly, the diver can separate the door 100 from the hull 10 even with a small number of people, and the time required for the separation of the door 100 can be reduced.

The door detachment unit 600 may include a turbine 610 and a power transmission unit 630.

The turbine 610 may be coupled to the receiving portion 200 to be disposed in the receiving space 210. As a result, the turbine 610 can generate a rotational force by the flow of seawater flowing into the receiving space 210 through the discharge port 230.

The power transmission portion 630 may include a pinion gear 631 and a rack gear 633.

The pinion gear 631 is coupled to the rotating shaft of the turbine 610 and can rotate together with the rotating shaft of the turbine 610.

The rack gear 633 may be formed in the longitudinal direction of the hinge shaft 20 and may be engaged with the pinion gear 631. The rotary shaft of the turbine 610 and the pinion gear 631 are rotated and the rack gear 633 that meshes with the pinion gear 631 is rotated. As a result, when the seawater flows into the receiving space 210 through the discharge port 230, Can be separated from the door 100 by raising the hinge shaft 20 on which the hinge shaft 20 is formed. A guide hole 250 may be formed in the receiving part 200 so as to pass through the receiving part 200 so that the hinge shaft 20 can pass therethrough.

The diving-inducing line ejecting apparatus of the sinking vessel according to an embodiment of the present invention may further include a piezoelectric element 700 and a light emitter 800.

The piezoelectric element 700 may be coupled to the receiving portion 200. As a result, the piezoelectric element 700 can generate electricity by water pressure when the receiving space 210 is filled with seawater.

The luminous body 800 can be coupled to the outside of the hull 10 so as to be adjacent to the outer doorway of the hull 10. For example, the light emitter 800 may be disposed so as to surround the outer doorway of the hull 10. The luminous body 800 can be emitted by the electricity generated in the piezoelectric element 700. As a result, the diver can easily identify the position and shape of the outer doorway of the door 100 or the hull 10 even in the dark sea floor, and the work environment for separating the door 100 can be improved.
