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.

    本发明涉及一种适用于水下无人潜航器的可靠对接及自毁装置和方法,解决了潜航器执行任务中可靠对接、顺利解脱、安全自毁、良好密封等问题。这是一种机电结合的装置,采用反行程自锁涡轮蜗杆减速器与齿轮齿条销传动相结合的模式,电机正向转动,锁定潜航器与对接口的相对位置,复用该传动设计,信息传输结束后,电机反向转动,通过滑块随齿条销正反向运动、来回触碰限位微动开关控制齿条销的运动位置,即可实现齿条销的伸出、回位、缩回。为防止下电后外液压作用下齿条销被压回,设计有较大的反向力矩。导向销与壳体固连,确保齿条销在固定的方向上移动。该装置通过了实航试验等多项试验验证,合理可行,效果良好。
