FIELD: acoustics, in particular, emission of hydro-acoustic encoded and broadband control signals.
SUBSTANCE: in accordance to invention, on each moving sunken object one or more emergency rescue buoys are located. Each emergency rescue buoy has waterproof body, preventing sinking of emergency rescue buoy or mechanical damage to it at all depths of assumed area of usage. Required resource of rope, having positive or zero floatability, depending on type of sunken object, is positioned either around the body of emergency rescue buoy or in a special container, fastened to exterior of sunken object. Located inside the body of emergency rescue buoy are blocks for receiving, amplifying and decoding hydro-acoustic signal Fes, block for decoding impact signals from inside sunken object, which is connected to output of amplification block in parallel to decoding block of hydro-acoustic encoded signal Fes, and also mechanical release, providing required rope tension after surfacing of emergency rescue buoy, digital information storage, ensuring continuous recording of all signals, incoming through receipt and amplification blocks starting from moment of activation of emergency rescue buoy hydrostat ending with finish of rescue operations, radio transmitter and high capacity supply block, charged once per year. Located on the body of emergency rescue buoy are: radiolocation antenna in transport variant, hydrostat, light reflector, reflector of radiolocation signals, pyrotechnic flash and flashing beacon.
EFFECT: fast detection, identification and determining of position across large area of a sunken object, quick preparation and lifting of same to sea surface or towing of same to shallow water, and also rescuing of people from sunken object in minimal time.
