Description

Pressure vessel-integrated lifting bag {Pressure vessel-integrated lifting bag}

The present invention relates to a pressure vessel-integrated lifting bag for the safe overturning of an overturned vessel, and more specifically, by integrating a pressure vessel and a lifting bag, it is easy to install and use on a vessel and can be used quickly in an emergency, resulting in a safety accident. It relates to a pressure container-integrated lifting bag for safe overturning of an overturned vessel that reduces the risk of overturning.

A ship is a structure designed to float on water carrying people or goods. A ship sailing on the sea receives external forces such as waves or wind. Heave, roll, pitch, and yaw.

In ships, rollover, in which the port or starboard side is tilted, occurs frequently, and since the area of the side of the ship is relatively larger than the area of the front or rear, it easily occurs due to a lot of resistance. There is a risk of continuing

In addition, when the weather deteriorates, the hull and cargo of the ship may be damaged due to wave impact, seawater intrusion, etc., and in severe cases, it may lead to marine accidents such as capsize or grounding, resulting in human life and property damage.

In the event of a capsize accident at sea, there is a risk of sinking at any time because the overturned ship has lost its safety. A bag is used as a device to prevent sinking by suspending a bag from an overturned ship.

A conventional lifting bag drags an air filling hose from a high-pressure container or compressor mounted on a ship to an overturned ship, combines it with an inlet and outlet valve, and injects air to form buoyancy. However, in this method, a very long filling hose is required. It is difficult to move it underwater, and in particular, it is almost impossible to do this in bad weather, putting rescuers and other rescuers in a dangerous situation.

In order to solve this problem, Korean Patent Publication No. 10-2012-0053107 discloses a technology related to an 'airbag for preventing sinking of a ship' that can delay sinking time by supporting a ship in a floating state by hanging it in an air bag. , As anti-sinking airbags must be provided inside the ship, space for installation must be prepared to apply to existing ships, and installation costs for remodeling or new installation of ship facilities are required, so ship owners install and apply them to ships There is a problem that makes them hesitate.

Accordingly, there is a need to develop a lifting bag that can be installed and used by rescuers on a rapidly overturned ship in order to prevent the ship from completely sinking and being flooded in the event of a ship accident.

According to a preferred embodiment, the lifting bag 10 forms a plurality of inflow and outflow valves 12 on both sides, so that when the lifting bag 10 is submerged in water, it is formed on the other side opposite to one side of the lifting bag that is relatively first entered into the water. Residual air inside is discharged by water pressure through the inflow and outflow valve 12, so that it can easily sink underwater and can be fastened to the bow and stern of an overturned ship.

At this time, the inflow and outflow valves 12 formed in the lifting bag 10 may be formed in plural at different locations so that the user can easily recognize them. This is because, as the lifting bag 10 is used in an emergency situation, if only one inflow and outflow valve 12 is formed in the lifting bag 10, it may be difficult to find the valve in an emergency situation.

Next, the pressure reducing valve 14 controls the amount of air injected into the lifting bag 10 from the pressure vessel 20 to be described later as the lifting bag 10 injects and fills the air to form buoyancy.

Specifically, the lifting bag 10 may cause a risk of bursting when air is injected in excess of an appropriate level, and accordingly, the pressure reducing valve 14 is formed on one side of the lifting bag 10 as a safety device to exceed the critical pressure. When air is injected, the pressure reducing valve 14 automatically operates to control the lifting bag 10 to maintain a constant pressure.

Here, the pressure reducing valve 14 according to the present invention is formed on one side of the lifting bag 10 to maintain the pressure of the lifting bag 10 at a constant pressure. At this time, the pressure reducing valve 14 of the lifting bag 10 It is appropriate to determine the pressure to be maintained according to the capacity, and according to a preferred embodiment, it is appropriate to maintain it at 0.1 bar.
