Specific features and advantages of the present invention will be described in detail below with reference to the accompanying drawings. The detailed description of the functions and configurations of the present invention will be omitted if it is determined that the gist of the present invention may be unnecessarily blurred.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an outline of an attachment type buoyancy device for delaying sinking of a tilted ship according to the present invention, and FIG. 2 is a perspective view showing an inner surface of an attachment type buoyancy device for delaying sinking of a tilted ship according to the present invention. Fig.

1 and 2, an attachment type buoyancy device for delaying sinking of a tilted vessel according to the present invention includes a cylindrical tube 100 having an empty space formed therein, A bomb 200 for supplying gas to the inside of the tube 100 to expand the tube 100, a plurality of detachable devices 300 formed on the outer surface of the tube 100 and detachable from the vessel, And a bombarding operation part 400 that is coupled to the tube 100 and protrudes to the outer surface of the tube 100 and operates the bombardment 200 so that the bombardment 200 can supply gas inside the tube 100.

In general, when the tube 100 is stored, a gas is not formed in the tube 100, and the tube 100 is flattened. Therefore, when the tube 100 is folded, the tube 100 is folded and stored. Respectively.

In this case, when the material of the tube 100 is made of synthetic rubber, it can be waterproofed, and it can withstand external impacts and external forces. Therefore, when buoyancy is formed after being attached to a ship, .

In addition, the tube 100 may be made of EVA (Ethylene-Vinyl Acetate), and the tube 100 made of EVA itself has buoyancy, so that the gas is introduced into the tube 100 Even if it is not injected into the water, it is possible to drift to the sea, waterproof, light and durable.

The bomb 200 refers to a pressure-resistant high-pressure gas container storing liquefied gas for expanding the tube 100, and the liquefied gas stored in the bomb 200 is stored in a liquefied state in a carbon dioxide or nitrogen mixed gas.

In addition, a safety device (not shown) is formed at a discharge port for discharging the liquefied gas from the cylinder 200, and a safety device (not shown) is removed by an explosion due to an electric signal or an external force, The tube 100 may be expanded by blowing gas into the tube 100.

The liquefied gas discharged from the cylinder 200 is quickly vaporized by the ambient temperature and discharged into the gas state. When the pressure of the liquefied gas discharged from the cylinder 200 is increased, the pressure inside the tube 100 is increased, Thereby allowing the tube 100 to have buoyancy.

The bomb operation unit 400 is connected to a safety device (not shown) formed at the discharge port of the bomb 200 and then protrudes through the tube 100. The protruded bomb operation unit 400 is electrically operated (Not shown) is formed which can form a sensor or physically remove the safety device (not shown) of the bomb 200.

At this time, the sensor of the cylinder operating part 400 is formed of a water sensing sensor capable of sensing water, and automatically activates the cylinder 200 when it senses water.

The water sensor is a sensor that measures the flow of current by flowing electric current to a longitudinally arranged electrode using the principle of electricity to water and measures whether the water is sensed or the water level, The more current is flowing in the water sensor, the less current flows.

In addition, a battery (not shown) may be provided inside the tube 100 to supply electricity to a water sensor and a safety device (not shown). In a stored state, a battery (not shown) (Not shown) supplies electric power to a safety device (not shown) so that the safety device can be released.

The safety device (not shown) closes the discharge port of the bomb 200, and when power is supplied, the explosive gas in the safety device explodes and separates from the bomb 200 to discharge the liquefied gas inside the bomb 200 through the discharge port .

A bobbin actuating part 400 may be provided with a line (not shown) that can apply an external force instead of a sensor and may be connected to the safety device (not shown) of the bomb 200 at the end of a line (Not shown) to release the safety device (not shown) to supply the liquefied gas stored in the cylinder 200 to the interior of the tube 100.

In order to delay the time required for the ship to sink using the buoyant force generated by the expansion of the liquefied gas discharged from the cylinder 200 inside the tube 100, And are formed on the outer surface in plural numbers.

Further, the desorption apparatus 300 is made of neodymium magnets and is automatically attached to the ship when the tube 100 is thrown to the outer side of the ship.

The detachment device 300 may be formed on one side or both sides of the tube 100 while being coupled to the tube 100 and may be formed on both sides of the tube 100 when the vessel is tilted and sunk, When it is thrown to the outside, it is attached to the outer surface of the ship by the magnetic force, and buoyancy can be transmitted to the ship.

At this time, if a water sensor is formed on the bombardment operating part 400, if the tube 100 is thrown in a direction in which the ship is tilted, the tube 100 automatically expands by sensing water, The tube 100 can be moved to the lower surface of the ship and can be attached to the outer surface of the ship by the magnetic force of the neodymium magnet.

Therefore, when the ship sinks, the buoyant force is formed on the ship by simply throwing the tube 100 in the sea, thereby delaying the sinking time, and the passenger can be evacuated as much as the delay time.

In addition, buoyancy may be formed inside the ship by throwing the tube 100 in the ship, or the tube 100 may be attached around the window formed on the ship. When water flowing from the window is sensed, the tube 100 expands, To reduce the amount of water flowing through the window.

FIG. 3 is a front view showing an attachment type buoyancy device for delaying sinking of a tilted ship according to the present invention installed on a side of a ship.

As shown in FIG. 3, the tubes of the buoyant buoyancy device for delaying the sinking of the tilted vessel according to the present invention are formed of a plurality of tubes, and the outer surfaces of the tubes are connected to each other. When the tube is thrown downward, the tube is attached to the side surface of the ship 10 due to the detachment device of FIG. 1 and then expanded to form buoyancy.

After forming a plurality of tubes, the outer circumferential surfaces of the tubes can be connected to each other, and the tubes connected to each other can be stored in the container 500 installed on the deck railing of the vessel 10.

In addition, when the bomb operation portion of FIG. 1 is formed as a sensor, it can be stored in the container 500 to prevent malfunction from moisture or rain, and it is possible to supply power to the container 500, Can be kept in a cushioning state.

When the vessel 10 tilts and sinks, the container 500 can be opened and the stored tube can be thrown. Since the tubes are connected to each other, even if only one tube is thrown, As shown in Fig.

1 formed in the tube is formed only in the tube attached to the lowermost end of the ship 10, and when water is detected in the lowermost tube, all connected tubes expand to form buoyancy.

In addition, the tube may be inflated by applying a physical force without using a sensor. In this case, a line (not shown) may be connected to the container 500 when the tube is thrown so that the tube is inflated simultaneously with thrown.

4 is a flowchart illustrating a method for delaying sinking of a tilted ship according to the present invention.

As shown in FIG. 4, the method of delaying the sinking of a tilted vessel according to the present invention includes an attaching step (S10) of attaching a plurality of unexpanded tubes to a side surface of a ship, (S20) for connecting the bomb operated portion formed in each of the tubes to the control device of the ship in a wireless or wired manner, and a control device connected to each bomb operated portion in the connection step (S20) An expansion preparation step (S30) for supplying power to the bomb operation part so that the tube in a direction in which the ship is tilted can be expanded when a predetermined time is reached at a predetermined angle, and a bomb operation part for supplying power in the expansion preparation step (S30) And an expansion step (S40) of expanding the tube by discharging gas from the bomb formed inside the tube when the vessel is tilted and comes into contact with water.

The attaching step S10 is a step of attaching the tube to the ship, and a non-inflated tube is attached to the side or inner surface of the ship so as to delay the sinking due to buoyancy generated in the tube when the ship tilts and sinks.

The neodymium magnet is formed on the side of the tube and can be freely attached to and detached from the surface of the vessel.

The wiring step S20 is connected to each of the bomb operation parts formed in the tube by controlling the bomb operation parts formed in the respective tubes attached to the inside or the inside of the vessel by connecting them with the control device of the ship.

In the expansion preparing step S30, when the vessel is maintained at a predetermined angle for a predetermined time, the controller of the ship supplies power to the bomb operation unit connected to each tube, and when the bomb operation unit detects water, And the power is supplied so that the operation part can supply the liquefied gas stored in the bomb to the tube.

At this time, the vessel is tilted at 30 to 40 degrees or more and the predetermined time is 60 to 180 seconds or more. The controller of the ship determines that the vessel is in a dangerous condition, As shown in FIG.

In addition, the control device of the ship may be configured to supply buoyancy by supplying power only to the bomb operated portion formed in the tilted direction.

In the inflating step S40, when each of the bomb operating parts supplied with power by the control device of the ship is exposed to water, the liquefied gas is discharged from the bomb storing the liquefied gas inside the tube so that buoyancy is formed in the tube .

At this time, the bomb operation part formed on the tube is composed of a water detection sensor and connected to the bomb formed inside the tube, and operates the bomb when the water is sensed.

Accordingly, when the ship is tilted and the tube is touched by water, the water sensing sensor in the state of being supplied with electric power senses it and supplies electric power to a safety device (not shown), and a safety device (not shown) And the explosive gas in the safety device is detached from the bomb by the supplied electric power so that the liquefied gas inside the bomb can be discharged through the discharge port.

As a result, the volume of the liquefied gas is increased by vaporization, and a high pressure is formed inside the tube, thereby forming a buoyancy force on the vessel and delaying the sinking time of the tube.

Also, the tube formed inside the cabin of the ship is attached around the window of the cabin. When the window is broken and the water is drawn in, the tube expands to reduce the amount of water to be drawn and buoyancy is formed inside.

When the ship is tilted and sunk, the water inside the cabin breaks due to the water pressure, and the water will flow in and cause the sinking time to be faster.

To solve this problem, the tube is attached around the window of the cabin, and when the water is drawn into the cabin due to the water pressure, the bombard operation part discharges the liquefied gas stored in the bomb to expand the tube to reduce the amount of water flowing through the window .

In addition, the tube formed inside each cabin expands to form buoyancy, so that the time to sink can be delayed.

As described above, according to the method of delaying sinking of a ship according to the present invention, buoyancy can be formed on the side of the ship when the ship is inclined sideways to delay the sinking time, When the tube is thrown toward the vessel, it is automatically attached to the vessel to form buoyancy. When the tube is stored, when the tube is shrunk and the water is sensed, the tube can be automatically expanded and used.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as a limitation of the scope of the present invention. Or modify it. The scope of the invention should, therefore, be construed in light of the claims set forth to cover many of such variations.
