ACOUSTICALLY DETONATED EXPLOSIVELY RELEASABLE LINK

摘要

An acoustically detonated explosively separable link (10) comprising a pair of bolt assemblies (36) mounted in spaced operative relation within the separable link parts (12 and 14), each of which includes a bolt (70) having a cavity (72) therein. An explosive (74) is provided in each cavity and an electrically actuated exploding bridge wire (76) is connected with each explosive for detonating the same. A miniaturized acoustical receiver assembly is mounted within the link parts and includes a hydrophone (42) for receiving a transmitted acoustical detonation signal, batteries (44) and circuitry (46) operatively connected with the hydrophone, the batteries and exploding bridge wires for conducting an electrical current from the batteries to the exploding bridge wires in response to the hydrophone receiving a transmitted acoustical detonation signal. A water pressure resistant container (40) is mounted within the link parts between the pair of spaced bolt assemblies for containing the batteries and circuitry including the operative connections thereof free from contact with water under pressure and for retaining the hydrophone in a position of proximity to water under pressure such as to receive an acoustical detonation signal transmitted through the water under pressure.
