The invention relates to an underwater shipbuilding, namely the rescue device submarines.

Known rescue device [1] submarine placed between a light and rugged. The main element of the device is inflatable pontoons from an elastic material, stored in an airtight storage with lids on cremallera constipation. Cover stores have a remote drive ottavani and discovery. The pontoons are secured to the hollow rod on a solid body. To them inside a solid casing through the side valves and dispensers the supplied compressed air.

Powered rescue device provides a surfacing submarine with depth and hold it on the surface in such position that the upper wheelhouse hatch was above the waterline.

A major shortcoming of the rescue device is the lack of reliability of the device consists in the fact that damage to one or more inflatable pontoons submarine loses its positive buoyancy. Damage to the pontoons may occur due to several factors. First, combat the effects in time of war. Secondly, the impact of broken ice in high latitudes. Thirdly, the bulk of the ship during the rescue operations. The influence of one or both NESCO is gcih the above factors will lead to the same result: inflatable pontoons, and therefore emergency submarine will lose buoyancy.

The aim of the invention is to improve the reliability of the rescue device by reducing the effects of inflatable pontoons of these factors. The aim is achieved in that the inflatable pontoons rescue devices are separated elastic bulkheads on a separate partition, compressed air which is supplied by a separate flexible tubes extending from the washers distributors in each hollow rod on a solid body.

Declared salvage and rescue device illustrated by the drawings. Figure 1 shows the submarine in two positions. The position of the waterline W₁L₁: emergency submarine is at a depth of and need emergency ascent, which she is unable to perform his regular system dive-surfacing. The position of the waterline W₂L₂: emergency submarine after actuation of the declared emergency rescue device surfaced, its upper wheelhouse hatch is above the current waterline. Figure 2 shows the cross-section between durable and lightweight case near one of the stores laid in it travelling inflatable pontoon. Figure 3 shows the cross-section AA or BB (midship) submarine in the two is alogene waterline: W ₁L₁- boat submerged, W₂L₂- boat surfaced under the force of the buoyancy of the pontoons.

Rescue device submarine consists of a hollow rod 1, which are attached to is divided into compartments inflatable pontoons 2 of flexible impervious material, such as reinforced rubber. Each pontoon 2 laid travelling in a rugged to withstand the water pressure at the maximum depth of the dive store 3, closed by a cover 4 with cremallera constipation 5. Vault 3 is placed between a light and strong body and attached (welded) to a solid body 6. The pontoon 2 is connected with varichem 7 on a solid body 6 of the hollow shaft 1, through which the compartments of the pontoons for flexible pipes is supplied compressed air from the ship's air system high pressure (VVD).

Inside the submarine on Varese 7 mounted side valve 8, which is connected by a pipe 9 with the dispenser 10, is connected to the ship's system VVD 11. Cover 4 store has the ability to open, turning on the axis 12. On the cover 4 has bglad with a light body 13 of the Radome 14. On the storage frame 3 is mounted actuator 15 opening cremalleras constipation 5. The actuator 16 of the opening cap 4 is mounted on the Foundation 17 mounted on the storage frame 3. Mechanism design covers and drives from the local and well established. The dispenser 10 and the storage 3 is connected with the outside space of the pipes 18 and 19 through the valve 20 mounted on Varese 21 on a solid body 6. The actuators 15 and 16 are connected by pipes 22 and 23 respectively with sockets 24 and 25 on the solid body 6 on which are mounted side valves 26 and 27. The valves 26 and 27 are connected with the ship's system VVD. On the shaft 1 is mounted a relief valve 28. The lower tapered portion of the inflatable pontoon 2 to prevent damage on the edges of the store 3 and the holes in the light housing 13 is placed in the flexible tube 29, which is fixed inside the lower part of the storage building 3.

Inside each compartment of all pontoons 2 installed flexible pipe 30 (one Bay - one pipe), one ends of which are attached to the upper compartment of the pontoon and the second ends of the pipe 30 is hermetically attached to the holes in the washers distributors 31, which are mounted on each of the hollow rod 1.

Rescue device submarine (lying on the ground or sinking) works as follows. Opening of the valve 20 is aligned with the pressure vault 3 with outboard. At the same time VVD is served in the dispenser 10 for adjusting the magnitude of the portion of the air supplied to the inflatable pontoon 2, to prevent its rupture. Opening of the valve 27 is supplied compressed air through the pipe 22 to the actuator 15 and turn opens crimal Erny constipation 5, then by opening the valve 25 the air is supplied through the pipe 23 to the actuator 16 and opens the lid 4.

Open mounted on Varese 7 side valve 8 and the pipe 9 dispenser 10 serves VVD in inflatable pontoon 2. Metered dispenser 10, the portion of the compressed air through the pipe 9 through the valve 8, the spindle 1, the washer-valve 31, the pipe 30 (Fig 3 depicts only one pipe goes to the top of the compartments of the inflatable pontoon 2, removing it by force of buoyancy from the storage 3. Then inflatable elastic pontoon filled the air with excess pressure over the sea by a small amount (1.0 to 1.5 ATM). Submarine receives positive buoyancy and begins the ascent. As it approaches the surface of the outboard pressure decreases, respectively, the volume of air in inflatable pontoon 1 is increased. In order not to break the pontoon 1 when approaching the surface, the excess compressed air is venting safety valve 28. At the end of the ascent to the surface, the submarine takes the position of the waterline W₂L₂. The tube 29 protects the pontoon 2 from damage on the edge of the light housing 13 and the upper edge of the storage 3 when the inevitable relative movement of the pontoons 2 and the hull of a submarine, especially when excited on the surface. In the position of the submarine W₂L₂the upper wheelhouse hatch 3 is located above the waterline, this allows you to open it for the evacuation of the affected part of the crew, ventilation submarine, replenishment of compressed air and perform other emergency and rescue operations, including the towing submarine rescue base.
