Description

Apparatus to prevent vessel from sinking}

The present invention relates to a ship sinking prevention device, and more particularly, to form an auxiliary buoyancy more than the absolute buoyancy that the ship does not sink so that the ship is prevented from sinking by the auxiliary buoyancy even if the vessel is flooded onboard by accident. The ships are, of course, designed to provide safety devices that do not require the passengers to escape from the ship.

As is well known, a ship that floats on the surface of the ship has a steel plate on the upper surface of the hull, and both edges in the longitudinal direction, i.e., the front and rear ends of the deck, consist of a shipboard.

These ships are usually equipped with life jackets or life tubes as part of emergency safety facilities resulting from accidental accidents such as collisions, grounding, fires, and explosions during sailing. The mandatory back is installed to maximize the safety of the crew and passengers.

In other words, in the event of a marine accident that causes a problem with the hull, people are able to escape safely and safely from the ship as quickly as possible.

However, the above-mentioned conventional ship safety facilities are not only insufficient for the occupants, but also allow the crew or passengers on board the ship to escape before the ship sinks at the moment of an accident such as a hull or fire. Even if the ship is overturned by a very severe typhoon and tsunami, even in the presence of severe storms or berths during voyage, even life preservers cannot protect lives.

In other words, in a situation where a ship can be severely shaken and overturned by extremely powerful external factors such as typhoons, storms, and tsunamis, using life-saving equipment to escape the ship will not only save lives but also pose more dangers. Even if you jump into the sea while wearing a life jacket in the sea, you can die due to a decrease in body temperature in just a few hours, and the ship can also sink, causing huge economic damage and inevitable problems.

In addition, if a sudden attack such as a torpedo is carried out by an enemy while sailing, the impact may cause death or loss of consciousness, and the ship may be divided into several parts and sink. In this case, the unfortunate event of sinking with the ship and losing its precious life occurs even if it is not dead.

The present invention has been proposed in view of this point, and it is necessary to prevent the ship from sinking by the auxiliary buoyancy even if the vessel is flooded onboard due to an accident by forming an auxiliary buoyancy above the absolute buoyancy that the ship does not sink. It is to provide a ship sinking prevention device that does not require the passengers to escape from the ship.

Will be the same as a normal ship.

In this state, when the ship encounters an accidental accident such as collision, stranding, storm, explosion, etc., the sensor 51 detects this and transmits a detection signal to the central processing unit 50. In 50, the locking means 12 is released to automatically open the opening and closing door 11 that has closed the storage compartment 10, and at the same time, the main valve 44 is opened to draw gas from the gas supply source 30. 20). In addition, in the case of manual operation, when the conductor finds the possibility of sinking of the ship, the manual operation switch 60 is turned on to release the locking means 12 and simultaneously open the main valve 44.

When gas is injected from the gas source 30 into the floating body 20, the folded floating body 20 swells and naturally exits the storage compartment 10, and the gas is continuously discharged from the gas source 30. As the floating body 20 is injected into the fluid 20, the floating body 20 is fully expanded to provide an auxiliary buoyancy to float the vessel 1. The gas supply pipe for injecting gas into the floating body 20 from the gas supply source 30 is provided. The injection nozzle 41 of the 40 is in the form of a venturi tube, and the injection nozzle 41 is connected to the guide plate 73 fixed to the front of the injection tube 71 of the partition wall 70 through the spacer 42. Since the gas is passed through the injection nozzle 41 in the form of a venturi tube, the injection speed becomes very fast and the pressure decreases while the air around the injection nozzle 41 is guide plate 73.

The solid line in the figure represents gas, and the silver line represents air.

In addition, in the present invention, since a plurality of injection pipes 71 are formed in the partition wall 70, and the injection nozzles 41 are provided in the same number as the injection pipes 71, the floating body 20 may be formed in a faster time. Gas and air can be filled.

In particular, since the liquefied gas can be applied to the gas supply source 30 in the present invention, a larger amount of gas can be liquefied to be stored in the gas cylinder 31, and the gas is floated in the float 20 instantaneously while the liquefied gas is vaporized. When the exhaust gas is applied to the gas supply source 30, it can be used to bypass the exhaust gas generated when operating the ship to the floating body 20 side without a separate gas, which can reduce the cost There is also an advantage.

In addition, since the inlet side is hermetically fixed to the side wall, the ceiling, and the bottom of the storage compartment 10, the inflated float 20 can prevent the float 20 from moving excessively, and the float 20 Even if the pressure is concentrated on the inlet 24 side of the c), the fixing part is wide enough to disperse the pressure as a whole, so that the fixing position of the floating body 20 can be maintained smoothly.

In addition, in the present invention, a plurality of storage compartments 10 are formed in proportion to the length of the ship 1, each of the storage compartments 10, the floating body 20, the partition wall 70, the gas supply source 30, Each of the gas supply pipes 40 is provided, for example, in the case of a ship 1 having a length of 30 m, the storage compartments 10 may be provided in units of 10 m each, so that collision, explosion, torpedo attack, etc. Even if the ship 1 is broken into several parts, at least one or more storage compartments 10, floating body 20 and gas supply source 30 may be provided in each part, so that each part of the separated ship 1 is The buoyancy can be provided so that each does not sink.

On the other hand, when gas and air are injected into the floating body 20 and the floating body 20 expands so that the vessel 1 does not sink, the reef or other damaged ship structure may come into contact with the floating body 20. In this process, when the floating body 20 is torn in such a process, there is a fear that the gas and air therein will escape to the outside and lose buoyancy.

To this end, in the present invention, the inside of the floating body 20 is composed of a sealing layer 21 made of a flexible material such as rubber, latex, flexible synthetic resin, and the like so that gas or air does not leak, and is sealed against a reef or a damaged ship structure. The outer side of the sealing layer 21 is composed of a fibrous layer 22 so as to protect the layer 21. In this case, the outer fibrous layer 22 having tough properties even when the reef or other structure collides with the floating body 20. ) Can protect the sealing layer 21 from most external forces to prevent the floating body 20 from being torn, and if the fiber layer 22 is pierced by a sharp structure, Even if the structure is in contact with the material, such as rubber, latex, flexible synthetic resin constituting the sealing layer 21, some impact can be repelled, even if the sealing layer 21 is slightly torn of the sealing layer 21 U A material according to the different parts of the surrounding properties have filled the water tightness of the torn portion so that the float 20 of the internal gas or air will be able to be prevented from escaping rapidly.
