The invention relates to the field of water ship rescue equipment, and discloses a pneumatic line throwing device for ship rescue. The device comprises a launching pipe body and a casting head, the side, away from the casting head, of the launching pipe body movably sleeves a piston plate, the launching pipe body fixedly sleeves a packing sleeve located at one side of the piston plate; a sliding sleeve is movably arranged in the packing sleeve in a sleeved mode, and an air guide groove located in the inner side of the packing sleeve is formed in the sliding sleeve. Through the linkage structure design of a positioning annular plate, the sliding sleeve, the piston plate and a limiting annular plate in the launching pipe body, after the casting head is launched through high-pressure gas, the piston plate moves to compress gas to enter an inner cavity between the packing sleeve and the limiting annular plate in the launching pipe body through the counter-acting force in the launching process; therefore, the high-pressure state is still kept in the inner cavity, the inflation time is saved during next inflation, the pressurizing efficiency is improved, and the launching rescue efficiency of the casting head is further improved.

    本发明涉及水上船舶救援设备领域,且公开了一种船舶救援气动抛绳器,包括发射管体和抛射头所述发射管体内部远离抛射头的一侧活动套装有活塞板,发射管体的内部固定套装有位于活塞板一侧的封隔套管,封隔套管的内部活动套装有滑动套管,滑动套管上开设有位于封隔套管内侧的导气槽。通过发射管体内定位环板、滑动套管、活塞板、限位环板的联动结构设计,在利用高压气体使得抛射头发射出去后,利用发射时的反作用力使得活塞板移动压缩气体进入到发射管体内封隔套管与限位环板之间的内腔中,从而使得该内腔中仍保持较高气压的状态,从而在下次充气时,节省了充气时间,提高了充压效率,进而提高抛射头的发射救援效率。
