RU2563292C2 - Rescue system for personnel rescue from nuclear-power submarine - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention relates to underwater engineering and can be used on nuclear-power submarines. System of life-saving rafts for personnel rescue from nuclear-power submarine consists of sealed containers with rafts. Rigid containers of life-saving raft system are incorporated into body of buoyant life-saving chamber. After the chamber has risen to sea surface, the rafts are automatically made operational. After mooring to the chamber, the rafts form integrated rescue group.

EFFECT: higher reliability and efficiency of personnel evacuation from life-saving chamber risen to sea surface.

Description

The invention relates to the field of underwater technology and can be used on nuclear submarines (ALL) of the Navy, equipped with rescue pop-up cameras (CWS), which ensure the evacuation of personnel from an emergency submarine lying on the ground.

In accordance with clause 4.1.2.22 of GOST RV 4220-001-2008, VSWRs may include liferafts that are placed outside the camera in special containers or inside it.

People who are in a very straitened position in the CWS, after surfacing, move to rafts designed for partial or full evacuation in order to create safer and more comfortable conditions for drift until the rescue forces approach.

Existing technical solutions for the placement and use of life rafts provide for the manual execution of all operations related to bringing rafts into working position, which is extremely difficult, unsafe and requires considerable time to complete them.

The aim of this invention is to increase the reliability and efficiency of the operation of the evacuation of personnel from the CWS that has surfaced to the surface of the sea, to life rafts by automating the process of bringing rafts into working position.

Using this technical proposal will improve security and reduce the time it takes to complete this operation.

The relevance of the invention is confirmed by the fact that the manual execution by the personnel of the operation of bringing the rafts into working position, when a person should be on the cowl cowl, is extremely difficult even with minor sea waves.

This goal is achieved by the fact that durable containers of the life raft complex (KSP) are included in the body of the KSV, which gives the whole structure additional buoyancy, improves its stability and increases the height of the freeboard. Improving these characteristics of the SWR will provide more favorable conditions for the crew to evacuate liferafts. The containers are positioned in such a way as to ensure remote opening of the lids and the release of rafts from the containers. The PCB can include up to four containers.

After separation of the CWS from the emergency submarine and its ascent, the lids of the strong containers are opened using pneumatic actuators. Then the rafts are pushed out of the container bodies with the help of pneumatic pushers and, when the gas filling system is automatically triggered, they are brought into working condition.

The operation of pneumatic actuators and pneumatic pushers is provided by the KSV compressed air system. Rafts are controlled from the SWR.

Rafts, being on the surface of the sea, are held near the SWR using special halyards. A team of two to three people pulls and moors the rafts to the camera, which form a single rescue group.

The crew through the upper hatch enters the deck of the CWS fairing and enters the rafts, drifting, depending on the situation, together with the CWS or independently.

The proposed technical solutions can also be used for the evacuation of personnel from an emergency nuclear submarine located on the sea surface.

When placing the SWR in the enclosure of the lifting mast devices (OP-MU) of the nuclear submarines, the rafts are brought into working position by remote control from the SWR according to the following scheme:

- lids of containers open;

- rafts are pushed out of the container and automatically brought into working position, being at the expense of the length of the halyard on the submarine deck;

- rafts in a certain sequence descend into the water from the leeward side of the nuclear submarine according to the scheme described in the patent of the Russian Federation for invention No. 2467915 of 11/27/2012

Figure 1 shows a variant of the SWR 1, placed in a nuclear submarine nuclear submarine and equipped with a PCB. The containers of the complex 2 are placed on the outside of the chamber under the fairing 3. In the initial position, the containers 2 are closed by folding sheets 4, mounted on the covers 5, the opening of which is carried out using pneumatic actuators 6.

Figure 2 shows the process of bringing the complex to its working position after the ASW 1 ascends to the sea surface. The rafts 7 are released from containers 2 after opening the covers of containers 5 by supplying compressed air from a cylinder located in KSV 1 through pipeline 8 to pneumatic actuators 6 of covers 5, and then through pipeline 9 to pneumatic pushers 10.

When the raft 7 is pushed out of the container 2 with a pneumatic pusher 10, the gas filling system of the raft 7 is automatically activated by tensioning and breaking the halyard 11. The raft 7 is brought into working condition and is gained from the VSWR 1 using the halyard 12.

Figure 3 shows the process of forming from rafts 7 a single rescue group 13, which is formed on the leeward side of the SWR 1, providing safer conditions for the evacuation of crew members. When forming a single rescue group 13, rafts 7 are moored and fixed to each other using ropes 14.

Subsequently, the rescued act in accordance with the instructions of the emergency and rescue service of the Navy.
