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 complexes (KSU-600N-4) using a device for storing and dropping a liferaft with an emergency submarine afloat (patent No. 2 236 982 of 06.20.2002).

At the same time, rafts are produced using pyrotechnic means and are provided only when the containers are in the above-water position.

Placement and storage of rafts of this complex on a submarine is carried out outside the sturdy hull of the boat in sturdy containers, which are usually located under its deck. Rafts are issued in two stages.

At the first stage, separation of the front cover of the container with a fairing of the submarine casing fixed to it is provided. According to the signal from the complex control system, pyro-bolts are initially destroyed, with the help of which the cover is attached to the body. In the future, the separation of the front cover with a fairing from the body is carried out by triggering by the control signal of the pushers located in the niches of the container body and mounted on the roof. When shooting, the cover with a fairing is dumped into the sea, forming a free niche for the exit of the package with the raft.

At the second stage, the raft packaging is pushed out of the container due to the gases generated when the pressure accumulators are triggered (PAD). These batteries are installed on a special board located in the inner cavity of the back cover of the container.

The gases formed during the operation of the PAD ensure that they fill the shell of the ejection mechanism located directly behind the raft packaging, and thereby exit the raft from the container body. Electrical equipment for controlling the process of shooting the front cover and the release of the raft is also located on the specified board along with the pad.

However, at critical values of the roll and trim of the emergency submarine afloat, the container with the raft may be in an underwater position, in which the front cover is additionally pressed against the container body by external hydrostatic pressure, which does not guarantee separation of the cover from the body and the formation of a free niche for exit raft.

In addition, when the container is in the underwater position after shooting the front cover, the outboard water entering the container’s internal cavities can lead to the failure of the electrical equipment of the raft release control system.

In a known container (patent No. 2236982), the tightness of the housing is ensured by sealing the front and rear covers. The back cover on the housing is secured with a ratchet lock. And as its mechanical seal, a cuff is used. The practice of using this cuff has shown that small leakages are possible at low values of external hydrostatic pressure.

The aim of this invention is the creation of a universal rescue complex for submarines, ensuring the release of life rafts from strong containers of the boat, located both above and below water, as well as ensuring the tightness of the container body along the seal unit of the back cover over the entire range of working depths.

The relevance of the invention is confirmed by the fact that when implementing these technical proposals, the complex will have new qualities that will increase its reliability and versatility.

These goals are achieved in that the guaranteed separation of the front cover with the fairing from the container body, located in the underwater position, occurs due to an increase in the piston stroke of the pusher, (its installation pattern is changed), in which its piston directly abuts the cover, most fully transmitting impulse to it from triggering pyrotechnic means.

This technical solution will allow the lid to completely exit the container body under the action of pyro-pushers and form a gap between them, through which water enters the container and equalizes the pressure with the outboard.

This will eliminate the action of the clamping force on the cover from external hydrostatic pressure and will contribute to its further movement under the action of its own weight.

In order to guarantee the preservation of the specified gap, a ledge is introduced into the structure of the support part of the cowl mount, which, after completion of the movement from the action of the pyro-pushers, ensures that the cover with the cowl is displaced downward by its own gravity, which excludes its return to its original position.

The operability of the electrical equipment of the raft release control system located on the board in the inner cavity of the back cover when filling the container with water is achieved by sealing this board by installing an o-ring.

The tightness of the container along the seal assembly of the back cover is ensured by a sealing ring (in contrast to the prototype, where the seal is provided by a cuff) and clamping devices made, for example, in the form of two reclining screw pairs (the prototype has a kremalier lock for crimping to working values).

The drawing (Fig. 1) shows a longitudinal section of the container 1 with the front cover 2, on which the cowl 3 is fixed, and the rear cover 4, fixed by means of clamping devices 5. Inside the container 1 is placed raft 6.

The drawing (Fig. 2) shows the back cover 4 with the board installed on it 7. The tightness of the board 7 and the internal cavity of the back cover 4, where the powder pressure accumulators (PAD) 8 and electrical equipment 9 are located, is ensured by means of a sealing ring 10.

The tightness of the container 1 on the sealing unit of the back cover 4 is ensured by installing a sealing ring 11, the working compression of which is carried out using two clamping devices 5. The clamping devices 5 are made in a folding form and are a screw pair.

The drawing (Fig. 3) shows the position of the front cover 2 with a cowl 3, at which the action of the pyro-pushers 12 on them ends and a gap is formed (see node B).

On the node And this figure shows a ledge 13, which eliminates in the underwater position the return of the cover 2 to its original position after moving under the action of the pushers 12 due to its lowering down under the action of gravity.
