FIELD: transportation, submarines. SUBSTANCE: submarine airlock chamber locking system incorporates an outboard water filling pipeline and a top cover automatically opening on equalising pressure inside the chamber with outboard pressure. A throttle water is furnished on the outboard water filling pipeline, provided with an adjustable membrane drive-linked to the pressure controller which, in its turn, communicates, via a pipeline, with the airlock chamber pressure pickup. EFFECT: air locking by outboard water in no-air conditions in the air system. 1 dwg
The invention relates to the field of rescue devices submarine (SUBMARINE), namely, the locking system locks chambers used in the output divers, emergency submarine rescue diving suit (SG). Can be used on submarines of the Navy. Known system locking devices individual rescue personnel SQ (special camera, cutting, torpedo tubes, and others)that have a water and air systems (Prasolov, S.N., Amicin MB Device submarines. M: Voenizdat, Ministry of defense, USSR, 1973, c.210-213). To implement locking submariner (divers) is in jeopardy, after which a water system, the cabin is filled with sea water up to the chest level of the diver, and the remaining air bag, the air is supplied from the air system PL. After pressure equalization in the wheelhouse with outboard submariner opens the top cover and floats to the surface. The disadvantage of this system sluicing is a long time to fill the cuttings with water, lack of control compression and manual opening of the top cover after pressure equalization, which reduces the depth of salvation (according to the modes of output, the longer the residence time of the diver under pressure, the less the depth with which you may secure the salvation). The closest in technical essence is the system locking single airlock (SHK), used to SQUARE the Royal Navy (Ovdienko NI Some directions to ensure survivability of submarines and safety of their personnel. - Sat. "Shipbuilding abroad", 1989, No. 8, pp.31-32 - prototype). The locking FRANKLIN is as follows. After entering the submariner in SHK her bottom cover is closed and the camera begins to fill sea water. When full, HQ water, as evidenced by the flow of water through the vent pipe inside DPS, the ventilation valve is closed, equalizing the pressure in the chamber with the outside, the air supplied to the rescue wetsuit, and in the air cushion chamber. Then is spring-loaded automatic opening of the lid and begins the process of free ascent. Remaining in the compartment of the SUBMARINE crew members closed using a special mechanism, the top cover and drain the camera, spilling water into the Bay. This camera greatly reduces the time of the diver under pressure by reducing time opening the top cover and provides rapid compression of air by the air supply from the air system PL, and into the air cushion FRANKLIN. The disadvantage of this system of locking is that it is impossible for the locking in the absence of the SQUARE of the air, which, as practice shows, the trail is a journey of accidents and emergency situations SQ. The technical purpose of this invention is the provision of locking sea water in the absence of air in the air system. This object is achieved in that the locking system airlock, containing the pipeline filling in sea water and the top cover that automatically opens when the pressure compensation inside the camera with saltwater, according to the invention on the pipeline filling with water installed throttle washer, provided with an adjustable diaphragm, which is connected to the drive pressure regulator, which in turn is connected by a pipe with the pressure sensor in the lock chamber. The technical result which is obtained by implementation of the present invention is to increase the depth and security of salvation, and the possibility of salvation in the absence of air in the air system emergency PL. Schematic diagram of the system locking airlock submarine is shown on the drawing. System locking airlock PL consists of a chamber 1, the bottom cover 2 and the top 3 with the spring-loaded automatic opening 4, the actuator 5 with the flywheel 6, pipeline filling the chamber with water from over the side 7 with shut-off valve 8. Before entering the pipe 7 is installed in the camera throttle washer 9 with the adjustable diaphragm 10, the result is 11 which is connected to the pressure regulator 12. Inside the chamber 1 posted by the pressure sensor 13, which is communicated with the pressure regulator 12 by line 14. Depending on the pressure in the chamber, the diameter of the aperture 10 is changed from the d0to d1where d0the diameter of the aperture in the initial compression; d1the diameter of the aperture at the end of compression. Submariner in the camera wearing a survival suit, the helmet 15 which is attached to tube 16 (cutoff element), which is part of the wetsuit with magnetic base 17 having a horizontal hole and a spring-loaded valve 18 (spring not shown). The system is as follows. The diver is wearing a survival suit, enters the chamber 1 and the tube 16 with magnetic base 17 attaches to the inner surface of the upper cover 3. When connecting magnetic base 17 with the cover 3, the valve stem 18 is released and the internal cavity of the helmet rescue wetsuit communicates with the atmosphere inside the chamber 1. After closing the bottom cover start compression (locking) by feeding water into the chamber from the side through the valve 8, the pipe 7 and the throttle washer 9. In the initial period of the diaphragm 10 has a minimum diameter d0. As the growth pressure in the air cushion SHK due to the increasing water level signal from the sensor 13 is supplied to the pressure regulator 12 and through the actuator 1 is an increase in the diameter of the aperture. The amount of water through the aperture increases, which increases the speed compression inherent in the regulatory law (the doubling of pressure for every 4-6 seconds). The air in the compressed water air cushion SHK through the hole in the magnetic base 17, the open valve 18 and the tube 16 enters the helmet rescue wetsuit, while breathing of the diver and preventing its compression. At the time of equalization of the pressure in the chamber 1 with the outboard spring-loaded automatic opening 4 overcomes the load of the water column above the lid 3 and the last offer. Magnetic base 17 is detached from the inner surface of the cover and the valve 18 is closed, thereby maintaining the required air volume inside the wetsuit. Due to its positive buoyancy of the diver ascends to the surface. After the release of the diver from the camera 1, remaining in the compartment divers close the lid 3 by the actuator 5, the rotating flywheel 6. The cycle then sluicing is repeated with the following submariner. Research conducted on the layout airlock, equipped proposed system sluicing, showed it is fully operational and able to provide the required compression mode. System locking airlock submarine containing the pipeline filling tabort the th water and the top cover, automatically opens when the pressure compensation inside the camera with saltwater, characterized in that the pipeline is filling with water installed throttle washer, provided with an adjustable diaphragm, which is connected to the drive pressure regulator, which in turn is connected by a pipe with the pressure sensor in the lock chamber.
