SU1062124A1 - Arrangement for emergency escape of people from ship - Google Patents

Description

The invention relates to the rescue of people and can be applied to the exit of people from an emergency vessel that is in an inverted position afloat.

A device for exiting people from an emergency vessel is known, comprising a lock chamber equipped with a hatch with a lid and in communication with the pneumatic system l.

A disadvantage of the known device is that it is installed on the ship during construction and may not always be in the place of the ship's hull from which people can be evacuated in case of an accident.

The aim of the invention is to accelerate the rescue of people from any compartment of the inverted vessel.

This goal is achieved by the fact that in the device for exit of people -. from the emergency vessel containing a lock chamber equipped with a hatch with a lid and communicated by a pneumatic system, the lock chamber is made removable from an elastic material, while in the upper part it is equipped with a safety valve, and in the lower part it is flanged with holes in which the square bolts are installed the cross section at the upper end and the restrictive ring at the lower end of dp excluding the permeability violation of the bottom plating of the vessel when welding these bolts to it by friction, the flange is made with an annular a peripheral inner chute equipped with an inner sealing chamber and connected to its bottom with the side wall of the sluice chamber, with the annular wall of the chute located inside the sluice chamber made with face skirt skiving, and the device is equipped with an additional removable sluice chamber fitted with an external hatch and front chute . A body valve and attached to a lyushluzoy X1 measure, which is mounted on the side wall of the latter. .

Figure 1 shows schematically the DEVICE, its view; figure 2 - section aa in figure 1.

On the bottom 1 of the vessel 2, a flange 3 is installed, having openings for bolts of 4 square cross section at the upper end. Between flange 3 and bottom 1, a restrictive ring 5 is installed. In the flange there is an annular peripheral inner groove b, inside

which is located the sealing chamber 7, connected through the nipple 8 and the hose 9 to the air compression system (not shown). A skirt seal 10 is attached to the walls of the gutter b, which circumferentially closes the opening in the bottom 1. A sluice chamber 11 with a safety valve 12 and a hatch 13 with a cover 14 is attached to the upper part of the chute b. An additional removable sluice chamber 15 with a safety valve 16 is attached to the hatch 13 , the hatch 17 and the KEY. 18. There are locknuts on the bolts 4 19.

The device is used as follows.

Airlock Ksuvtepy 11 is deployed and installed with a flange 3 on the bottom 1 of an inverted vessel 2. Install the bolts 4 in the holes in the flange 3, which have a cutout under the restrictive rings 5 equal to half the thickness of the bottom plating 1. With a drilling machine and an allen key, rotate each bolt 4 to its friction welding with the bottom. When the bolt 4 rotates, the locknut 19 is unscrewed so that it does not interfere with friction welding.

After removing the drilling machine, lock nuts 19 are screwed to capacity. From the pneumatic system, through the hose 9, through the nipple 8, compressed air is supplied to the sealing chamber 7. Through the hatch 13, the worker enters the lock chamber 11 and closes the cover 14. Compressed air is supplied to the inside of the chamber 11, and the safety valve 12 is regulated to the required pressure. The worker with a mechanical device or a gas-cutting machine cuts a hole in the bottom 1. At this time, an additional lock chamber 15 is installed on the hatch, the cover 18 is closed and the chamber 15 is filled with compressed air until the pressure in the chambers 11 and 15 is equalized. the chamber 11, then passes into the chamber 15. The hatch 14 is closed, then the hatch 17 is opened, and it goes out. After that, the hatch 17 is closed, the pressure in KciMepe 15 is equalized with the pressure in chamber 11, the hatch 13 is opened and the device is ready for transferring the next saved one.

The technical advantage of the proposed device is its transportability and applicability to all ships.
