Description

 The invention relates to the field of underwater shipbuilding and can be effectively used to create underwater vehicles with increased survivability and a high probability of rescue of the entire crew in emergency situations.

 Underwater vehicles are known that are equipped with pop-up rescue chambers or personal rescue equipment to ensure the safety of the crew or its evacuation in emergency conditions.

 A well-known submarine, including compartments located in a strong hull, a control system, a launch shaft with a pop-up camera placed in it, equipped with life support and control systems, additional buoyancy aids, crew hatches and elastic guides associated with the camera bailout / RF patent 2149123 prior. 12/11/97, IPC 7 V 63 G 8/40, 8/41 /. The evacuation of the crew, which in the event of an accident passes through the hatches into an airtight chamber, is carried out by ejecting the camera from the submarine’s launch shaft with the shaft’s cover open previously.

 However, in spite of the fact that crew rescue is possible from a depth extremely permissible for a solid boat hull, the disadvantage of the known device is the impossibility of crew rescue in cases where the launch shaft, pop-up camera or control system are damaged, since the rescue camera in this case is not may surface, in addition, there is no guarantee of the salvation of the entire crew, as people will not be able to go to the rescue chamber if there are emergency compartments in their path, which may be outboard boiling water, high temperature or increased radiation.

 A submarine vehicle, in particular a submarine, is known which includes at least one transverse bulkhead with hermetically sealed hatches, which separates two insulated compartments, as well as at least one pop-up chamber, which is connected via said hatch to said compartments in a corresponding position relative to the transverse sealed bulkheads, a rescue chamber is attached to the hull of the boat from the outside with the possibility of separation during an accident / application of Germany 2434766, prior. 07.19.74, IPC B 63 G 8/40 /. A disadvantage of the known submarine vehicle is the ability to save only a limited number of crew members.

 A submarine vehicle is known, in particular an underwater tanker (project, Sweden), including insulated durable hulls connected by strong tunnels, sealed bulkheads with adjustable hatches and at least one pop-up camera / I.A. Bykhovsky. Nuclear submarines. Ed. 2nd. Sudpromgiz. L., 1963, p.207-211, Fig. 109 /. The corridors and tunnels provided for by the design of the tanker are designed to interconnect four separate strong tanker hulls for passage of personnel from one hull to another.

 Structurally, corridors and tunnels are extensions of strong hulls, representing displacement volumes designed for full outboard pressure.

 However, these corridors and mines do not solve the problem of people passing through the emergency compartment to go to the rescue chamber, they do not allow people to go through the emergency compartment to the compartment adjacent to it to organize the struggle for survivability in it, and thus they do not ensure the rescue of all personnel in different compartments. In emergency situations, the command post cannot fully perform its functions, which reduces the effectiveness of the struggle for the survivability of the vessel; in addition, it is impossible to ensure decontamination and other measures to reduce the threat to the life of the crew.

 A well-known submarine, including at least one strong hull with corridors and mine tunnels, configured to attach a rescue chamber to it, is selected as the closest analogue of the invention.

 The objective of the invention is to increase the effectiveness of emergency rescue measures of the crew by creating on-board emergency-protected premises.

 The problem is solved in that in an underwater vessel comprising at least one sturdy hull with compartments and a corridor configured to attach a rescue pop-up camera to it, in accordance with the invention, the corridor is placed longitudinally in the direction of the axis of the sturdy hull at the level of the upper deck, made the ability to connect to each of the adjacent compartments by means of hatches, is partitioned and has a baffle for accommodating a spare command post, the arch of which is combined with a durable case and includes a hatch made with the possibility of interfacing with the entrance to the pop-up rescue chamber, while the corridor is thermally insulated along the entire length and equipped with sealing means.

 In addition, the partitioning of the corridor is performed by means of the inter-compartment bulkheads of the vessel, on which the access hatches are made.

 In addition, the partition to accommodate the emergency command post is made solid.

 The technical result consists in the constructive allocation within the solid hull of a submarine (submarine) of an emergency-protected room with an autonomous emergency control and life support system - a "safety corridor", which allows the entire crew of the submarine to significantly expand the capabilities of the struggle for survivability of the vessel and its effectiveness or leave it in case of a serious accident.

 The invention is shown in FIG. 1, which is a schematic representation of a submarine vehicle (sectional view) illustrating the location and equipment of a corridor (“safety corridor”) on a ship, and also FIG. 2 and 3, representing the cross section of the corridor at the place of its interface with the compartment and with the pop-up camera, respectively.

 The submarine includes a strong hull (1), an outer light hull (2), on which a wheelhouse guard (3) is installed. The sturdy case (1) is divided by inter-compartment bulkheads (4) into functional compartments, in one of which is the main command post located in the bow of the sturdy case (1). A pop-up camera (5) is interfaced with a strong body, located in the area of the wheelhouse guard (3).

 The corridor (6) extends in the longitudinal direction along the axis of the vessel, exit from it into the end compartments of the submarine is through end hatches (7), and access to the compartments adjacent to the corridor (6) is through hatches (8) made in the walls of the corridor (6 ), and the passage along the corridor (6) through the inter-compartment bulkheads (4) - through the shut-off hatches (9) made in them.

 In the area adjoining the strong body (1) of the pop-up chamber (5) in the corridor (6), by means of vertical partitions (walls), a partition (10) is formed, the upper arch of which is combined with a strong body (1), so that the partition (10) has an exit into the pop-up camera (5) through the hatch (11) (Fig. 1), and into the corridor (6), on both sides, through the hatches (8) (Figs. 1, 3). The partition (10) is designed to accommodate a reserve command post, which can be involved in an emergency. The baffle (10) is made solid, its walls are designed for the required pressure. The corridor (6) is located at the level of the upper deck (12).

 To protect the team from damaging factors (fire, seawater intake, radiation), the corridor is thermally insulated, and it is also equipped with volumetric sealing means that provide reliable cut-off of damaged compartments from the corridor (6), in particular, seals. Through the corridor (6) pass emergency power cables, control, communications, lighting and emergency pipelines. The height of the corridor is determined by the requirement that the crew pass through it in full height.

 The emergency command post in the baffle (10) is equipped with backup power control facilities, facilities that enable the ascent of the ship, movement and radio communications.

 When operating under normal conditions, the corridor (6) provides the crew with a through passage to all compartments of the submarine.

In the event of an accident, during the fight for the survivability of the vessel, the corridor (6) ensures that the crew passes from the emergency compartment to any other one, preventing the spread of damaging factors (fire, flooding, radiation) to neighboring compartments both by isolating the emergency compartment and by intensive ventilation or air purification (in case of fire) sections of the corridor passing through the emergency compartment, into which smoke may enter when people exit the burning compartment into the corridor (figure 1)
In an emergency, the main command post provides for the transfer of the command of the ship from it to the baffle (10), in which the spare command post is located, to continue the struggle for survivability and control the emergency ship.

 To save personnel in the event of an accident and the threat of the death of the vessel, crew members from any compartment can go into the baffle (10) under the protection of the strong-weighted structure of the corridor (6) and land through the hatch (12) into the pop-up camera (5) for subsequent surfacing .

 In case of damage or failure of the rescue pop-up camera (5) and inability to leave the submarine in it, the crew passes along the corridor (6) to its stern, to the stern rescue hatch (13) equipped with a device for receiving the underwater rescue apparatus, or the crew gets the opportunity to exit to the surface by free ascent using individual rescue equipment.

 To increase safety on board, it is possible to create a gaseous environment with a lower oxygen content in the most fire hazardous compartments, while the crew passes through the corridor (6) through the corresponding compartment without violating the sealing of this compartment.

 When operating a submarine with such a safety corridor, the probability of rescue of the entire crew in an emergency increases, and opportunities for measures to combat the survivability of the vessel expand.
