Reliable butt joint and self-destruction device and method suitable for underwater unmanned underwater vehicle

Abstract

The invention relates to a reliable butt joint and self-destruction device and method suitable for an underwater unmanned underwater vehicle, and solves the problems of reliable butt joint, smooth release, safe self-destruction, good sealing and the like in task execution of the underwater vehicle. The device is an electromechanical combination device, the mode that a reverse stroke self-locking turbine worm reducer and gear rack pin transmission are combined is adopted, a motor rotates forwards, the relative position of the underwater vehicle and a butt joint opening is locked, the transmission design is reused, and after information transmission is finished, the motor rotates reversely; the sliding block moves forwards and backwards along with a rack pin, and touches a limiting microswitch back and forth to control the movement position of the rack pin, so that the rack pin can extend out, return and retract. In order to prevent the rack pin from being pressed back under the action of external hydraulic pressure after power-off, large reverse torque is designed. A guide pin is fixedly connected with a shell, and it is ensured that the rack pin moves in the fixed direction. The device is verified by multiple tests such as a real navigation test, and is reasonable, feasible and good in effect.

Description

technical field [0001] The invention relates to a device suitable for reliable docking and safe self-destruction of an underwater unmanned submersible. Background technique [0002] After the underwater unmanned submersible has completed the prescribed tasks, it is often necessary to use the docking method to transmit the acquired information to the host computer. In order to ensure the stable transmission of information, the key lies in whether the docking process is reliable or not. The instability or deviation of the docking process , may lead to failure of information transmission or lack of information, resulting in misinterpretation of information and affecting major decisions. In addition, in order to ensure the safety of information and data, after the submersible has completed the data reporting, it should be able to self-destruct in time. The key to the self-destruction function is to self-destruct in a timely and normal manner according to the self-destruction com...

Problems solved by technology

[0004] The technical problem solved by the present invention is: in order to solve the defects of unreliable docking and hidden dangers in the safety of self-destruction of unmanned submersibles under the conditions of limited structural space and strict weight restrictions, this solution is aimed at small-caliber underwater unmanned vehicles. To meet the requirements of high mission reliability of submersibles, a device with small size and light weight is designed, which can realize stable docking and safe self-destruction at the same time, which can be used as a reference for other types of underwater unmanned submersibles
