The invention provides an unlocking device and method for a flow guide cover plate of an inflatable life raft system. The device comprises a base, a mounting platform, the flow guide cover plate and a rotary unlocking air cylinder. The flow guide cover plate is in contact with the upper surface of the butt joint ring, locking piece mounting positions are distributed on the flow guide cover plate and are in threaded fit with the upper section of the screw rod, and the lower section of the screw rod penetrates through the butt joint ring and is in threaded fit with a butt joint hole in the rotary unlocking air cylinder; the butt joint hole is formed in the connecting shaft in the axial direction of the connecting shaft. The rotary unlocking air cylinder comprises a connecting shaft, an air cylinder base, an upper cylinder body, a lower cylinder body, a ventilation cavity, a piston rod and an elastic piece. According to the rotary unlocking air cylinder, the axial movement and the rotary movement of the connecting shaft are controlled by controlling the conduction condition of external air and the two vent holes, separation of the locking piece and the connecting shaft is achieved, the release process is convenient, and release faults are avoided.

    本发明提出了一种气胀式救生筏系统导流盖板解锁装置及方法,该装置包括底座、安装平台、导流盖板和旋转解锁气缸;导流盖板与对接环的上表面接触,其上分布有紧锁件安装位,紧锁件安装位与螺杆的上段螺纹配合,螺杆的下段穿过对接环,并与旋转解锁气缸上的对接孔螺纹配合;对接孔沿连接轴的轴向开设于连接轴;旋转解锁气缸包括连接轴、气缸座、上缸体、下缸体、通气腔、活塞杆、弹性件;本发明中的旋转解锁气缸通过控制外部气体和两个通气孔的导通情况,控制连接轴的轴向运动和旋转运动,实现紧锁件与连接轴的分离,释放过程方便,避免发生释放故障。
