A self-destruction device for an underwater vehicle

Abstract

The invention discloses a self-destruction device for underwater vehicle. The self-destruction device comprises a permeable seat, wherein the permeable seat is fixed on the inner side of the wall of an airtight cabin through locking nuts; three O-shaped rings guarantee the water tightness of a compressive cabin; an electric resistance wire penetrates through a fusing hole of a plastic check block;the plastic check block presses a permeable spring into a cavity of the permeable seat; the two ends of the electric resistance wire extend out from the other end of the cavity of the permeable seat;two metal pressing blocks separately press the two ends of the electric resistance wire on a plastic pressing block; the permeable seat limits the position of the plastic pressing block; the metal pressing blocks and the plastic pressing block lock the electric resistance wire and maintain the permeable spring to be at a compressed state; two O-shaped rings on the plastic check block are positioned on the two sides of a permeable hole of the permeable seat; wires are led out from the two ends of the electric resistance wire to an alkaline battery; a normally open relay is connected in serieswith the middle of the wires; the control terminal of the normally open relay is connected to a main control panel. The self-destruction device utilizes a simple and miniature structure, is simple tocontrol and high in reliability, and can rapidly guide seawater to enter the interior of the underwater vehicle, to achieve the self-destruction purpose, and is widely applied to various underwater platforms requiring self destruction.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a self-destruction device for an underwater vehicle. Background technique [0002] In recent years, with the continuous deepening of people's exploration of the ocean, underwater vehicles, as an underwater detection device with wide coverage, flexible maneuverability, high concealment, and low cost, are widely used in intelligence / surveillance / reconnaissance, mine countermeasures , anti-submarine warfare, detection / identification, oceanography, communication / navigation network nodes, payload delivery, information warfare, and time-sensitive strikes. Underwater vehicles can perform special missions in sensitive waters and, if necessary, self-destruct to avoid detection. [0003] The application of underwater vehicles to military purposes in our country is still short, and the research on the self-sinking of underwater vehicles is still blank. [0004] In order to ensure that a ...
