RU2611859C2 - Device for liferaft holding above emergency submarines lying on ground and method of its application - Google Patents

Abstract

FIELD: transportation.

SUBSTANCE: in order to allow the divers leaving the emergency submarine lying on the ground to get to the life rafts, that were released and are maintained on the sea surface above the submarine, the diver shall float to the sea surface and swim to the released raft. Diver's position is fixed by retention by the arc, with a fixed ring, through which the guide wire is passed. After the wetsuit carbine connection to the rope portion located above the arc, the diver swims to the surface.

EFFECT: assurance of saved submariners getting in the raft.

Description

The invention relates to the field of underwater technology and can be used on submarines (submarines) of the Navy (Navy) and other submarine objects.

Known universal rescue systems, which are equipped with submarines. At the same time, liferafts are placed in strong containers that ensure their release and acceptance of their working position under the surface and underwater positions of the emergency submarine (patent RU No. 2467915 of 11/27/2012).

When the emergency submarine is overboard, the personnel jumps into the water, swims to the raft, which is held by a 20–25 meter long halyard at its side, and according to the well-established methodology, climbs and places it inside the raft.

When the emergency submarine is in the submerged position, the submariner leaves it through the rescue hatch, floats according to the accepted procedure to the surface of the water, swims up to the liferaft pre-released from the submarine, climbs in and places it.

However, in this situation, the rescued after surfacing to the surface may be at a considerable distance from the raft (more than 20 meters), which will not allow him, especially in conditions of sea waves, to get into the raft, which means there is a danger to his life.

The aim of the present invention is to provide a device that will allow the submariner to leave the emergency submarine lying on the ground through the rescue hatch along the guide cable directly near the liferaft, released in advance from the emergency submarine and located above it on the sea surface. In this case, a guide cable is used to hold the liferaft over the emergency submarine.

This invention is relevant for all types of submarines equipped with rescue hatches, providing rescue operations from depths of the sea up to 220 meters using the free ascent method in rescue equipment of a submarine equipped with an air supply unit.

This invention will significantly improve the efficiency of rescue operations using the free ascent method through the rescue hatch of the submarine due to the guaranteed getting of the rescued into the raft and ensuring maintenance of their vital activity until the approach of the forces of the Navy rescue service.

The specified goal is achieved by the fact that:

- The submarine is equipped with a guiding device with a drive, consisting of an arc (handrail), made in the form of a semicircle, which is located on the outer diameter of the coaming area of the rescue hatch;

- the arc in the working position is located at an angle above the rescue hatch, providing working contact with the rescue when it leaves the emergency submarine through the rescue hatch;

- in the middle part of the arc, a ring is fixed, through which a cable passes, which raises the raft on the sea surface above the emergency submarine;

- a container with a raft and a view with a winding cable wound around it are placed in the immediate vicinity of the coaming area;

- the free end of the cable is fixed on the container, which, when kicked up, floats to the surface of the sea under the influence of its own buoyancy, unwinding the cable from the view;

- after the raft is released and brought to its working position on the sea surface, it is held above the emergency submarine by means of a locking device that provides etching of the required cable length depending on the depth of the sea at the accident site;

- in the working position, the arc occupies a position above the rescue hatch, the raft is on the surface of the sea, and the cable, passing through the ring fixed on the arch, is positioned above the rescue hatch;

- when leaving the emergency submarine, the submariner, without losing contact with the rescue hatch and holding onto the arc, fastens the wetsuit carbine to the section of the cable located above the arc ring;

- the submariner, at the expense of its own buoyancy force, holding onto the cable, floats to the surface and ends up at the raft;

- holding on to the raft railer, the submariner unfastens the carbine from the rope and makes the transition to the raft to maintain life until the approach of the Navy rescue service.

The scheme of ascent and bringing the raft into working position corresponds to the scheme given in patent RU No. 2467915.

With this design of the guide device, it is possible to place several liferafts around the coaming area, the halyards of which will pass through several rings located in the middle of the device’s arc.

The drawing (Fig. 1, 2) shows a structural diagram of a guide device in the "marching" position. Arc 1 is made of a pipe, and its ends are fixed in brackets 2. A pneumohydro cylinder can be used as a drive 3. A container 4 with a raft 5 and a view 6 are placed in the area of the coaming area 7 of the rescue hatch 8. In this case, the possessing cable 9 passes through the ring 10 located on the arc 1.

The drawing (Fig. 3) shows the working position of the arc 1 of the guide device and the diagram of its use. Ring 10 in the working position of the arc occupies a position that ensures the passage of the halyard above the rescue hatch.

The method of using the device includes:

- installation of the arc 1 in the working position and the release of containers 5 from the niches of the submarine housing;

- exit submariner from the rescue hatch 8 and fixing its position by holding the arc 1;

- connecting the carbine of the wetsuit in the area of the cable 9, located above the arc 1;

- ascent of submariners due to their own buoyancy force along the guide cable 9 to the sea surface near the raft 5;

- ensuring the working contact of the submariners with the raft 5 by holding the rail 11;

- detachment of the carbine of the wetsuit of the submariner from the halyard 9 and transition to the raft 5.
