Method of rescuing crew of emergency submarine lying on ground / 2274583

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another without locking through well of rescue hatch of section-shelter of emergency submarine till the whole crew is withdrawn out of the section-shelter.

Device for coupling submersible rescue vehicle with underwater object and method of coupling by means of this device / 2250858

The invention relates to the field of diving equipment, namely the means of salvation divers, emergency submarine (PL) with the help of divers, and can be used on rescue vessels of the Navy.

Famous diving gazebo for descent of the diver to the workplace and the rise of conducting decompression regime. The gazebo has a metal base (platform) with reinforcing struts (Bulekov S.E. and other Reference items. M: Voenizdat, 1973, s).

The disadvantage of this gazebo is the possibility of hypothermia diver when lifting its long-term decompression mode.

The closest in technical essence and the achieved result is diving gazebo, which is made with the heating element, for example, electric, placed in permeable casing mounted on the base, and sliding casing, flanges, suspended in the upper part of the uprights. When lowered bottom flange of the protective cover surrounds the diver thermal protection. The hose breathing gas mixture (CSD) from the surface skipped under the bottom flange of the arbor and attached to the diving equipment (A.S. USSR №495892, VS 11/28, 1975 - prototype).

The disadvantage of this gazebo is the impossibility of its use for decompression group, for example, when divers emergency is L. In addition, this design does not provide for the filing of CSD in breathing apparatuses (IDA) rescued submariners, this can result in a lack of CSD in the long decompression due to the small number of these units.

The technical objective of the invention is the provision of group rescue divers with long decompression.

This object is achieved in that in a diving gazebo containing base with reinforcing struts, seat heating element and protective sliding elastic casing, according to the invention the seat is made bench with individual switches heating elements and on the basis of fixed-filled breathing gas mixture cylinder with pressure reducer, the output of which has a manifold with hoses at the ends of which are mate quick couplings for connection to a breathing apparatus and a hose passed through the protective covers for each seat.

The technical result from the use of the invention is to increase the probability of rescue divers, emergency PL.

Figure 1 shows a schematic diagram of diving gazebo.

Figure 2 shows a schematic diagram of the seat.

Diving arbor (figure 1) consists of the base 1 with reinforcing struts 2, seats 3 and protective sliding elastic covers 4. Based on 1 fixed cylinder 5 with gear 6, the output of which is the collector 7 hose 8. In the upper part of the reinforcing struts 2 attached stretch marks from lifting cable 9, as to the basis 1 - cargo 10.

Under each seat 3 (figure 2) are the individual heating elements 11 with switches 12 that are connected by cables to a junction box 13, box 13 are connected to a common cable 14 to the surface. Individual heating elements 11 are permeable top housings 15, which together with the seat is fixed on the base 1. On the seat 3 are submariners 16, dressed in saving equipment with IDA 17. On each IDA 17 are quick coupling 18, second part which are located on the ends of the hoses 8. Hoses 8 are passed through the protective covers 4 to each of the seat 3 and the lower part of the housings 4 are flanges 19, is lowered onto the housing 15.

Work diving gazebos as follows.

When deciding on release divers, emergency PL, lying on the ground, to the exit hatch gateway device, such as a torpedo apparatus, rescue boat is lowered diving gazebo on the cable 9 (Fig 1). Previously on the surface of the container 5 is filled with the desired d is I the depth of the output of the CSD. Diving arbor falls on running cable, pre-wound divers to a place out of submariners. The group fleeing divers came out of the SQUARE, is placed on the seat 3 and hoses 8 using quick couplings 18 (2) attach IDA for breathing from the tank 5 through the reduction gear 6 and the collector 7. After placing rescued in the gazebo begins the ascent to the surface at the required decompression regime under the control of the divers rescue vessel.

In the case of cooling saving each individual feelings pulls the flange 19 of the protective cover 4 to the housing 15 and the switch 12 activates the heating element 11. The power to each heating element 11 is supplied on a single cable 14 through the switch box 13 and the individual switches 12. Heated water from the heating element 11 through the permeable top of the casing 15 through the casing 4 and by convection moves to the top of the casing, forming a heat shield around saving. If necessary, each saving can turn off the heating.

After rising to the surface rescued off heating, lift the protective cover 4, disable IDA 17 from the hose 8 and transferred to the deck of the rescue ship.

The number of seats 3 based on 1 diving gazebos varies in the depending on the type of gateway device emergency PL.

Thus, diving gazebo increases the likelihood of rescue divers, emergency DPS at the expense of group saving and increase comfort during prolonged decompression.

Diving gazebo containing base with reinforcing struts, seat heating element and protective sliding enclosure, characterized in that the seat bench made with individual switches heating elements and on the basis of fixed-filled breathing gas mixture cylinder with pressure reducer, the output of which has a manifold with hoses at the ends of which are mate quick couplings for connection to a breathing apparatus and a hose passed through the protective covers for each seat.
