Description

Automatic Buoyancy Supply Unit in Ships

The present invention relates to an automatic buoyancy supply device of a ship, in particular, by confirming that the seawater flows into the hull through a sensor that can detect the seawater flowing into the hull, the confirmed signal (confirmed signal) confirmed by the sensor automatically To the solenoid valve, which opens the solenoid valve, which opens the pneumatic valve connected through the pressure reservoir and the pipe, thereby injecting compressed air from the pressure reservoir into the air tube, thereby confirming At the same time, by inflating the air tube, several air tubes simultaneously act as a buoyancy on the hull to keep the ship horizontal and maintain the maximum time for the ship to sink to the ship that can induce an emergency escape of the crew on board the ship. Relates to an automatic buoyancy supply device.

In general, ships that operate rivers, lakes or seas are made of steel, non-ferrous metals, wood or plastics, and various types of ships are suitable for cruise ships, high speed boats, fishing boats, and boating, depending on the purpose of use. However, the above-mentioned ships may sink due to the influence of external shocks or bad weather caused by collisions during operation.

In order to protect the vessel and occupants from the sinking of the vessel can be provided with a separate device that can increase the buoyancy during the construction of the ship bar as an example of the Republic of Korea Utility Model Registration No. 0262867 is buoyancy material on the inner surface of both side walls of the hull The buoyant material has a space therein and is formed in the form of a tube filled with air such as air or helium or buoyant foam such as styrofoam and fixed to the hull to improve the buoyancy of the ship and at the same time the external impact To protect the hull and prevent it from sinking during a sea accident such as a part of the bottom of the hull being damaged or overturned, and the Korean Utility Model Registration No. 0422289 consists of a combination of upper and lower bodies of a ship. Sinking of vessels constructed by filling light and low density buoyant materials of low moisture density inside the hull An prevention structure is disclosed.

In addition, Korean Patent Application Publication No. 2000-0066906 discloses a plurality of door-shaped box bodies at regular intervals on the left and right upper circumferential surfaces of the ship body, and installs a door opening and closing device and an air bag in the box body installed inside the door. By connecting the hose and pipe and installing the operation valve, when the operation button is pressed during the ship's distress, the door is opened by the compressed air and the discharged air bag is inflated to generate buoyancy to prevent the ship from sinking in the water. The sinking prevention device of the is disclosed.

However, these sinking prevention devices are difficult to install in the existing vessel because it adds a separate buoyancy material to increase the additional buoyancy during the construction of the ship, and does not provide a separate buoyancy to the vessel sunk by external impacts The problem of not being able to prevent the sinking of the ship or the ship's occupant must operate the operation button manually as the ship sinks, so it is difficult to deal with the situation when the ship sinks due to abrupt ship overturning and provide air to the airbag. There is a problem in that the space for installing the compressed air tank and the accessories connected thereto is complicated and the device is complicated.

In addition, in case of a normal ship sinking, the ship's hull submerged in an instant, so the emergency escape time of the passenger or crew is short, and the hull is not leveled, resulting in a situation where the hull splits into two pieces. This can be seen through. Accordingly, the present inventors have considered a device that can induce an emergency escape of the crew members aboard the ship by extending the time when the hull sinks as much as possible and keeping the hull horizontal when the ship sinks.

The present invention is conceived under the background as described above, by confirming that the seawater is introduced into the hull through a sensor that can detect the seawater flowing into the hull, the confirmed signal (confirmed signal) automatically confirmed by the sensor solenoid It is delivered to the valve, and the opening of the solenoid valve opens the pneumatic valve connected through the pressure reservoir and the pipe, which injects compressed air from the pressure reservoir into the air tube, which almost simultaneously with the seawater inflow of the sensor. By inflating the tube, several air tubes simultaneously act as a buoyancy on the hull to keep the ship horizontal and maintain the maximum time for the ship to sink so that the ship's automatic evacuation is possible. The purpose is to provide a buoyancy supply device.

In order to achieve the above object, the present invention provides a plurality of level sensors for monitoring the inflow of seawater into the hull, an alarm and monitoring system for monitoring the inflow of seawater and sending a signal to operate the alarm and valve, high pressure compression An air compressor that generates air, an air tank that holds compressed air generated from the air compressor for engine operation and other operations on a ship, and a solenoid valve that automatically opens and closes with an electrical signal from the pressure reservoir, the alarm and monitoring system, A pneumatic valve operated by pneumatic pressure by supplying air by opening the solenoid valve, an air tube supplied with air from the pressure reservoir to maintain buoyancy, a buried case in which the air tube is embedded in the hull, and a malfunction of the device Emergency operations configured to work in an emergency situation It characterized in that it comprises a button.

According to the present invention, by installing an air tube in the hull of the sinking ship to inject compressed air into the air tube during the crisis of the ship sinking, a plurality of air tubes act as buoyancy on the hull to keep the hull horizontal in the water By prolonging the sinking time as much as possible, it is possible to obtain the effect of contributing to the emergency escape and smooth rescue work of the crew.

Shown).

The operation of the automatic buoyancy supply device of the ship of the present invention configured as described above will be described.

First, the seawater inflow is detected by the level sensor, that is, the level transmitter 1 into the hull. When the majority of the sensors detect the inflow of seawater, i.e. when 8 out of the 12 sensors detect the inflow of seawater, for example by the voting principle of out of number (OON), A converted signal or alarm signal informing of inflow is transmitted from the level sensor to the alarm and monitoring system 2. The level sensor may be a leak sensor that detects a liquid, but is not limited thereto. The level sensor generates an open signal for automatically opening the solenoid valve 5 to actuate the air tube with the generation of a conformed signal. Then, the solenoid valve 5 is opened by the open signal for opening the solenoid valve, and the pneumatic valve 6 is opened by the opening of the solenoid valve 5. The high pressure compressed air is then supplied from the pressure reservoir 3 to the air tube 7 by opening the pneumatic valve 6. When the high pressure compressed air is supplied to the air tube 7, the hull is kept horizontal due to the buoyancy force of the plurality of air tubes, as shown in FIG. 3b of the air tube, thereby extending the sinking time of the hull as much as possible. Emergency escape of crew and the like can be induced from the hull. On the other hand, the supply of compressed air to the air tube 7 can be supplied to the plurality of air tubes simultaneously or sequentially.

On the other hand, in case of a blockage of the air supply main route (not shown), a separate line for supplying air is provided by pressing the push button 8 in case of an emergency in the local emergency, resulting in malfunction of the device. Configure it to work smoothly.

As shown in the figure, the fixing device includes a plurality of compressed air discharge openings 7a for discharging compressed air from the air compressor 4 of FIG. And a plurality of fixing devices 7b for fixing the air tube to the hull.

Figure 3e shows a perspective view of the air tube unfolded state of the automatic buoyancy supply device of the present invention. As shown in the figure, the air tube 7 is formed in a U-shape, but is not limited to such a shape, and may be any shape as long as it can maintain the buoyancy of the air tube well.

In addition, the air tube has a bellows-shaped longitudinal cross-sectional shape in which the surface area of the air tube expands when deployed. Therefore, the air tube has a different surface area when it is expanded when it is contracted.

According to the present invention, by installing an air tube in the hull of the sinking ship to inject compressed air during the sinking crisis to maximize the sinking time of the ship due to the buoyancy of the plurality of air tubes, and maintain the ship horizontally in the water for a certain period of time By doing so, it is possible to obtain an effect that can contribute to the emergency escape of the crew and the smooth rescue operation.
