Description

The invention relates to the field of shipbuilding, namely to rescue equipment of submarines (submarines).

A well-known rescue pop-up camera (SWR), including a spherical body with upper and lower entrance hatches, a device for fixing on a submarine case, life support equipment, pushers and technological eyes for lifting and installing on a submarine case in factory conditions [1].

The disadvantages of the camera are:

- the upper hatch low above the waterline, flooded with water with slight excitement;

- constructive incompatibility of the means of lifting the CWS from the water (technological jacks) with the response parts of the launching and lifting devices (SPU) of rescue vessels;

- incompatibility of the design of the lower hatch of the SWR with the device for securing it to the coaming of the receiving-output compartment (AA) of the decompression chamber (DC) of the vessel;

- lack of a towing device,

which does not allow people to be taken out of the CWS during sea disturbance, decompressed on board the ship and delivered to the CWS at the base point.

The known design of the SWR with a vertical housing, installed on a submarine carrier rescue underwater vehicle (SPA), which allows for the decompression of submarines rescued with the help of SPA in the pressure chamber of the SWR [2] (prototype). Decompression is provided using communications linking the SWR chamber to the PL carrier.

The disadvantages of the prototype is that when the CWS ascends to the surface, the escape of those rescued through the upper hatch afloat during sea waves is impossible; the high altitude of the SWR does not allow lifting it to the deck of the vessel and installing it on the coaming of the air defense of the recreation center; the design of the lower hatch is incompatible with the device for securing it to the DC air defense coaming; A device for towing an SWR is not provided.

These shortcomings do not ensure the rescue of people from the SWR when it emerges to the surface and towing the SWR to the base.

The objective of the invention is to ensure the rescue of people from the SWR and its towing in conditions of sea excitement.

The problem is solved by the fact that on the body of the VSWR there is an inflatable fence of the upper hatch with valves for supplying and filling the enclosure with air, controlled both from the hatch of the hatch and from inside the SWR; rod devices (ШУ) with guide ropes are provided; the supporting ring is welded with conical tides at the end of the lower hatch; A towing device is installed in the waterline area.

The proposed technical solution has significant advantages over the prototype, providing:

- the exit of submariners from the SWR to the hatch enclosure during sea waves;

- the rise of the CWS, which emerged from the emergency submarine, onto the deck of a rescue vessel under sea conditions;

- decompression of submariners in the decompression complex of a rescue vessel;

- towing the SWR.

The invention is illustrated by drawings.

Figure 1 schematically shows the design of the SWR.

The housing 1 KSV is made in the form of a horizontal cylinder with spherical shells at the extremities. The upper access hatch 2 is equipped with a retractable flexible guard 3. To install the guard 3 in the working position, the filling valve 14. The air for filling the enclosure 3 is supplied from the cylinder 15 by the supply valve 16. The valves 14 and 16 are controlled both from the outside and from the inside of the CWS (view A). Outside the enclosure technological eyes are installed 4. Rod ends 5 with guide ropes 6 are provided at the ends of the housing 1. Rod devices 5 are installed in the notch of the fairing 7. The design of the control gear is given in [3]. The housing is equipped with a towing device 8 in the form of a butt. The lower hatch 9 in the airlock 10 is equipped with a support ring 11 with conical tides 12 (type B). The conical tides 12 interact with a clamping device of a kremalier type, fixing the support ring 11 with the air defense coaming of the recreation center (similar to attaching the SWR to the submarine housing). Hydraulic pushers 13 are located behind the airlock 10, which serve to separate the CWS from the emergency submarine hull.

In Fig.2 shows a view of the SWR taken on suspension by a launching and lifting device for lifting on board, and on the deck of the vessel after installation on the coaming of the air defense DC.

SWR devices work as follows.

To raise the CWS on board the vessel using SPU 17, the submariners set the hatch 3 fence by opening the valves 16 and 14 from the inside of the CWS, open the cover of the upper hatch 2 and transfer the guide ropes 6 of the rod devices to the rescue vessel 18 with a line thrower. The submarines return to the CWS and close the manhole cover.

If there is excessive pressure in the SWR, the guide wires of the SHU are transferred to the vessel by the rescuers. If the fence 3 of the hatch 2 by the submariners is not installed, the rescuers, after landing on the VSWR, can install it themselves by opening the valves 14 and 16 from the outside of the VSWR housing.

On the vessel, the guide ropes 6 of SHU 5 are connected to the guide ropes 19 passing through the automatic grips (ZA) 20 of the cargo blocks 21 of the SPU 17. The bridge of the SPU 17 is rolled overboard. Automatic winch guiding ropes are included in the tracking mode for the constant tension of the ropes 19. Along the guiding ropes 19 freight ropes 22 with the help of the winch 23, the cargo blocks 21 with automatic grippers 20 are lowered.

After docking automatic capture 20 with SHU 5, the cargo ropes 22 are transferred to the tracking mode, maintaining a constant tension force. The system of automatic selection of the lifting moment ensures the lifting of the SWR by the freight ropes 22 from the top of the wave.

After raising the SWR to the final switch of the cargo winch, the SPU 17 bridge rolls aboard the vessel. The SWR is lowered by the support ring 11 to the coaming 24 of the decompression complex of the vessel. The tides 12 of the support ring 11 are pressed against the coaming of the air defense 24 by a ship-type device of a cremallera type.

The pressure between the compartments of the SWR, air defense and recreation center is equalized. Submariners are moving from SWR to air defense DC. In the absence of excess pressure in the SWR, the exit from the air defense is provided to the room of the decompression chambers. At overpressure in the CWS, submariners transfer from air defense to a decompression chamber for decompression. Patients and injured are provided with primary medical care.

After the transition of the divers, the covers of the passageways are closed. Excessive pressure in the SWR is removed and it is being prepared for towing.

The root end of the towing cable is wound from the outside into the ship's lock and secured in the holder. The running end is worn along the side to the launching position. The fire of the running end of the tow rope is connected to the towbar 8 KSV bracket. The clamping device release the support ring 11 of the SWR.

The SWR is raised from coaming 24 air defense and lowered into the water. SPU is restored to its original position.

The ship is given a turn, and the CWS is shifted aft from the lowering and lifting position.

The vessel lays on the set course and starts towing the CWS. The location of the towing device 8 of the SWR in the area of the waterline provides controlled towing.

The proposed design of the CWS, in contrast to the prototype, provides not only the emergence of the crew of the emergency submarine in the CWS to the surface, but also the lifting of the CWS on board the rescue vessel in stormy conditions, the rapid evacuation of submarines, including those who have lost activity, from the CWS to the vessel and providing them with primary medical assistance, decompression in ship's conditions, as well as towing the CWS to the home base.

The design is new, useful, simple. The possibility of introducing the proposed technical solutions is beyond doubt. The use of the proposed design of the SWR on modern and promising submarines solves the important problem for the Navy to save the crew of the emergency submarine from the compartments with normal and high pressure in stormy conditions.
