Description

The invention relates to the field of underwater technology and can be used on submarines (submarines) when performing rescue operations.

Known design of the universal surface rescue complex (KSU-N) according to RF patent No. 2436704 (IPC В63С 9/22, B63G 8/00, В63С 9/02, application No. 2010103696, filing date 02/03/2010), which is designed to rescue personnel emergency submarine, located on the surface. The universal surface rescue complex consists of sealed containers with rafts placed in them. The containers are equipped with motorized front covers for opening them. They are located in the fencing of the submarine lifting and mast device. Raft release is carried out using a raft release device powered by a submarine compressed air system. In this case, the rafts in the initial position for landing are on the lateral inclined surface of the submarine hull.

However, the launch of the raft into the water of the known technical solution is carried out after the members of the submarine crew have embarked in it, which leads to large loads on the raft in the place where the carbine of the holding device is attached, which does not fully guarantee the reliability and safety of evacuation of people using life rafts in sea conditions under sea agitation over 1.5 points.

The solutions known today to ensure the evacuation of people from surface vessels: USSR author's certificate No. 1594062 (IPC В63В 27/14, application No. 4409080, filing date 04/13/1988), US patent No. 4684079 (IPC B64D 25/14, B64D 25/00, application US No. 19850809088, filing date 12/13/1985) cannot be used with submarines according to the conditions of their placement and storage under external influence of hydrostatic pressure.

The technical result of the claimed invention is the creation of a universal rescue complex (KSU), which provides guaranteed landing in sea conditions of crews of emergency submarines in life rafts.

The relevance of the invention is confirmed by the fact that the issues of ensuring guaranteed landing of the emergency submarine personnel into rafts in sea conditions have not yet been resolved.

The specified technical result is achieved by the fact that the universal rescue complex for a submarine on the surface includes life rafts placed on the submarine. It provides boarding of rescued crew members in rafts during evacuation operations. The complex includes an evacuation device that ensures the guaranteed landing of the crew members of the emergency submarine in the life rafts.

The evacuation device consists of a rope-launching device and a "railing" cable attached to the submarine. The "railing" cable is a guiding element, fixed at the second end at the entrance to the liferaft, and ensures that the rescued crew members from the emergency submarine get onto the raft. Loops are formed at the ends of the rope-descent device cable and braces are inserted into them, which are attached to the "railing" cable during descent.

Moreover, the number of evacuation devices corresponds to the number of the complex's rafts deployed on the submarine. The "guardrail" is equipped with a carabiner and a clamp that allows it to be tensioned before descent of those rescued from an emergency submarine.

In addition, the rope-launching device and the "fixed rope" of the evacuation device with the help of carbines are fixed on the eyelets installed on the deck of the submarine.

The claimed invention is illustrated in FIG. 1 and FIG. 2.

The drawing (Fig. 1) shows the composition and design of the UE.

The drawing (Fig. 2) shows a diagram of the use of UE.

UE consists of a rope-escapement device (UCS) and a "railing" cable. UKS is the main element of the UE and is a modified rope-and-descent fire-fighting device with automatic maintenance of the specified descent speed "Samospas" according to TU 4854-002-88345304-10 (hereinafter - the device "Samospas"), which is used to evacuate people from high-rise buildings. The Samospas device consists of a braking unit with a cable, at the ends of which rescue scarves are fixed. This device allows the rescuer to descend at a given speed under the action of its own weight. In this case, the device works like a rocker: when the rescued descends down at one end of the cable, the other end of the cable rises to its original position for the next person to descend.

The UKS has been improved in terms of dismantling the gussets of the "Samospas" device, ensuring the required length of the cable and forming loops at its ends, to which the braces are attached. In this case, the length of the UKS cable is determined by the submarine freeboard height with which it is used.

The "railing" cable is a guiding element of the UE, which is fixed at one end to the submarine, and the other end is fixed at the entrance to the inside of the life raft, into which people are evacuated. The "guardrail" cable is equipped with a carabiner and a clamp that allows it to be tensioned before people descend.

The drawing (Fig. 1) shows the composition and design of the UE.

UE consists of a UKS 1 and a "railing" cable 2.

UKS 1 includes a brake unit 3 with a loaded cable 5 of the "Samospas" device, at the ends of which loops 6 are formed and braces 7 are wound. The brake unit 3 is equipped with a carbine 4.

"Railing" cable 2, equipped with a snap hook 8 and a clamp 9.

The drawing (Fig. 2) shows a diagram of the use of the evacuation device 10, with the help of which the rescued 11 descends from the emergency submarine into the raft 12.

In submarine conditions, the KSU complex equipped with a UE is used according to a scheme that provides for the sequential performance of the following operations:

- release of the raft, bringing it into working condition and pulling it (mooring) to the submarine board with the help of a halyard;

- fastening on the eyelets installed on the submarine deck, using UKS carbines and a "rail" rope;

- dropping of the long end of the UKS and the "fixed" cable from the submarine deck in the direction of the moored raft;

- the first descent crew member, wearing a rescue immersion suit (GTKS), being on deck, fixes the GTKS carbine to the loop of the UKS cable end and descends into the raft, possessed (moored) at the submarine side.

- after getting into the raft, he fixes the second end of the "rail" cable at the entrance to the raft and takes out its slack with the help of a clamp. Detaches the GTKS carbine from the UKS cable;

- after the descent of the first rescued, the second end of the UCS, rising, turns out to be in the area where the UE is attached to the deck;

- the second descent, fixes the GTKS carabiner to the end of the UKS cable, starts the guy behind the "fixed" cable and, using it as a guide, descends into the raft;

- after the completion of the descent and transition to the raft, the rescued person unhooks the GTKS carbine from the UKS, and the guy line from the "fixed" cable and is placed in the raft.

The estimated number of crew members accommodated in a given raft is alternately descent into it according to the second descent scheme.

In this case, the first descendant provides insurance for subsequent descendants in the part of their hitting the raft entrance area and the transition into it.

From the emergency submarine, evacuation is carried out simultaneously to all rafts of the complex launched into the water.

Thus, the claimed universal rescue complex (KSU) provides guaranteed landing in sea conditions of crews of emergency submarines in life rafts.
