Method of rescuing crew of emergency submarine lying on ground

FIELD: rescue methods.

SUBSTANCE: method of rescuing crew from section-shelter of emergency submarine lying on ground along flexible pipeline being under pressure is based upon displacement of rescued crew inside pipeline by means of winch into section-shelter of rescuing submarine follower by subsequent decompression of rescued crew if necessary. Flexible pipeline is mounted between comings-areas of emergency and rescue submarines by sing robot-manipulator. After extraction of water from pipeline the pressure is created inside pipeline which pressure is equal to that one in section-shelter of emergency submarine. Crew is displaced one member after another without locking through well of rescue hatch of section-shelter of emergency submarine till the whole crew is withdrawn out of the section-shelter.

EFFECT: more efficient and quick process of rescue.

The invention relates to the field of rescue divers and can be used to move divers compartments emergency submarine (submarine), lying on the ground, to another PL "dry" method on the pipeline, consisting of a flexible corrugated and rigid sections, installed through the robotic arm between the coaming areas of emergency and saving coal-seam

To well-known a number of ways to rescue the crews of emergency dps currently include:

1. The way of salvation divers, emergency PL, lying on the ground, "dry" method using the pop-up rescue chamber (CWS) (see RO PL-87, Voenizdat, Moscow, 1987), consisting in the transition divers compartment disaster square in the CWS, CWS Department with fleeing emergency PL and the ascent to the water surface.

The disadvantages of the method are:

- the complexity of the docking CWS with decompression compartment rescue vessel (SS).

- the possibility of lifting the CWS on Board the SS unlikely in the rescue operation;

- the possibility of salvation from the ice is associated with considerable technical difficulties.

2. The way of salvation divers, emergency PL, lying on the ground, "dry" method using deep-sea rescue apparatus (MUH) (see RO PL-87, Voenizdat, Moscow, 1987), consisting in the translation group of rescued submariners (about 20 people who age) MUH, docked to the coaming-site emergency dps, and the ascent of MUH with saving to the surface.

The disadvantages of the method are:

- the restriction of the use of MUH on the intensities of the sea (up to 4 points);

- duration MUH depends on the energy resource rechargeable batteries, designed for 10-hour load;

- docking MUH when the roll (pitch) emergency dps more than 45 degrees is practically impossible without additional complex technical solutions;

- relatively small capacity MUH (no more than 20 people).

3. The way of salvation using special rescue sq Ave 940 type "Goldilocks".

The disadvantages of the method are:

the necessity of dressing rescued submariners in special our waterproof garment for subsequent compressione and transfer them "wet" method involving divers, lifeguards in the decompression chamber rescue sq;

is a substantial likelihood of hypothermia rescue divers.

4. The way of salvation from the ice using rubber hoses with connecting flanges, which consists in installing the sleeve through the lane in the middle of the ice on the coaming-pad primenenii dps, for transfer of the divers on the surface of the ice (Registered in the State register of the USSR on may 4, 1987 Copyright certificate №253270);

- the impossibility of its application at a depth of 20 meters and the impossibility of salvation divers compartments with high blood pressure.

The closest in essence to the proposed method of salvation is the way of salvation divers, emergency PL, lying on the ground, "dry" method for flexible Gavrilovna transport pipeline (GGT) under pressure in a decompression chamber on the rescue ship, the proposed 40-m state research Institute of the Ministry of defense (Notification of the positive result of the formal examination No. 844 of may 21, 2000). GGT is established between the coaming area emergency PL and receiving the output compartment decompression module rescue vessel fleeing divers undergo compression in rescue emergency hatch square and moved by a lift in a decompression chamber on Board a rescue.

The main disadvantages of this method are the following:

- the need for a rescue vessel multi-purpose type "piece";

- the inability to apply when the sea is rough, more than 5 points;

is not ensured secrecy of salvation.

The task of the invention is to improve the efficiency of the existing system of salvation sunken emergency pl.

The task is solved in that the proposed way of salvation supply is of IKI from the Bay of refuge emergency PL, lying on the ground, by a flexible pipe under pressure, move rescued submariners in the pipeline with the help of the winch in the Bay-shelter-saving square, followed, if necessary, decompression rescued submariners. In the role of saving using a different PL, equipped with a portable rescue complex. A flexible conduit consisting of a flexible corrugated and rigid sections, is placed between the coaming areas of emergency and saving PL using the robotic arm. After displacing the sea water from the pipeline of high pressure air, it creates a pressure equal to the pressure in the compartment-emergency shelter bed

Another difference is that salvation divers perform consistently without sluicing through the mine rescue hatch compartment-emergency shelter dps to full output from the Bay shelters the entire crew.

The proposal of this method comes from the following considerations:

1). Almost every existing combat dps can carry special equipment to assist other dps, if not required to make any more or less complex design solutions for transportation of such equipment.

2). Assistance to the crews of sunken and lying on the ground at depths greater than 100 m emergency dps most effectively m which can be implemented PL, which for this could lie on the ground (all diesel submarines) or as an anchor (nuclear submarine), was able to fix its position relative to the emergency. The maximum possible depth of the salvation of the proposed method will be limited to a maximum depth used for dps (˜400÷600 m).

3). The bedding on the ground next to the emergency dps is more preferable from the viewpoint of fixing regarding emergency dps, for a number of projects nuclear submarine these issues are resolved.

4). As major funds, which must be equipped saving dps, as mentioned, can be extreme strength Flex, as well as a special robotic arm to install the pipeline between rescue emergency hatches and saving pl. Diagram of the operation of salvation presented in figure 1, (1) - emergency PL; (2) - saving PL; (3) flexible tubing; (4) to the robot arm; (5) rescue hatches square

6). Currently developed technology to create high-strength composite materials with a specified strength-based polymers, epoxy resins with fillers type Kevlar, Twaron, carbon filaments, etc. from which you can make a pipe that can withstand internal and external static pressure 1.5-2 MPa, which is interesting from the point of view of implementation of the method. The manufacture of such materials is s Flex, reinforced metals, can improve the strength characteristics of the pipe in two and more times. The piping layout is presented in figure 2.

7). Currently in the Park robotics has a robotic arm that can perform the task of installing the pipeline between PL-PL, opening the hatch emergency dps, as well as for communication between PL-square diagram of the robot arm are presented in figure 3. Transportation of the robot arm can be performed in a container that can be mounted behind the stern of the rescue hatch saving dps, and can be discarded upon arrival in the bedding area emergency pl.

8). Questions docking pipeline manholes PL technically solved with the help of docking units, similar to those used in space technology, but modified for the conditions of the marine environment.

9). Ensuring acceptable conditions rescue crews from the point of view of deep-sea physiology feasible at this level of development of diving physiology.

10). The most important properties of the proposed method of salvation is the independence of the process of salvation from the weather and a small dependence on the undercurrents, the possibility of salvation from the ice, ensuring the secrecy of the process of salvation that hostilities can play a decisive role.

11). With best what part this method differs that, in principle, does not require the use of divers glubokovodniki.

12). Development, production and implementation of equipment portable rescue system to ensure this method of salvation, taking his service in the Navy would be much increased the radius of a possible rescue crews. Considering the fact that the portable rescue complex can be delivered almost anywhere in the world ocean using transport aircraft, and, in the future, can be installed on any square, the likely radius of salvation may be limited.

A walking robot manipulator is a new generation of robot-technical systems. The role of the root hinge is integral blocks alternately. In the manipulator implemented a new structure of the universal management system: modular, Multicontroller with open network structure. The control system is distributed in the joints of the manipulator and practically integrated with its mechanics and actuators based on brushless type DBM. Distribution management system pointing device associated with the management of the upper-level computer, which is integrated into the onboard network management space station, ship, vessel, etc.

The offered way of salvation is more radical and complex the m in the implementation, other than the well-known, however, initial analysis of the reality of its application in the near future gives encouraging results.

The real possibility of making the transport pipeline confirmed in JSC special machinery (hotkovo Sergiyev-Posad district, Moscow region), which was performed preliminary design and technology development pipeline.

Holding if necessary decompression saved will be in the Bay-shelter-saving square and does not represent a significant problem because there is additional equipment compartments-havens PL from the 3rd generation and later for the purpose of decompression.

Thus, the preliminary study allows to draw a conclusion about the reality of the proposed method crew emergency submarine lying on the ground.

The way of salvation divers from the Bay of refuge emergency submarine lying on the ground, by a flexible pipe under pressure, including moving rescued submariners in the pipeline with the help of the winch in the Bay-shelter-saving submarine, followed, if necessary, decompression rescued submariners, characterized in that the flexible tubing set between the coaming areas of emergency and saving submarines using the Obote arm, after displacing the sea water out of the pipe it creates a pressure equal to the pressure in the compartment-emergency shelter submarine, and the movement of divers perform consistently without sluicing through the mine rescue chamber hatch-seekers emergency submarine to the full output from this compartment refuge of the entire crew.
