The invention relates to the technical field of fire-fighting lifesaving equipment, and discloses a long-distance lifesaving throwing device. The device comprises a gas cylinder cover. According to the long-distance lifesaving throwing device, an ascending section outer barrel and a descending section outer barrel can be separated in the air through clearance fit of the ascending section outer barrel and the descending section outer barrel and connection of a nitrogen dioxide gas cylinder, a connector, a trigger, a floating bag and a descending pull rope, under shape arrangement of a sliding sealing rod, after an ascending pull rope pulls the sliding sealing rod, a gap is formed between the lower portion of the sliding sealing rod and a partition plate, meanwhile, the transverse section ofthe sliding sealing rod can extrude water in a water chamber to be discharged through the gap and make contact with a trigger piece, and therefore a valve is opened, gas in the nitrogen dioxide gas cylinder is inflated into the floating bag, and the floating bag expands to impact a second connecting cylinder to push the second connecting cylinder. The ascending section outer barrel is separated from the descending section outer barrel, and the descending pull rope in the second connecting barrel is pulled out, so that a lifesaving elastic head is pushed for the second time to fly, and the throwing distance of the device is further increased.
本发明涉及消防救生设备技术领域,且公开了一种远距离救生抛投器,包括气瓶罩。该远距离救生抛投器,通过上升段外筒与下降段外筒的间隙配合,并在二氧化氮气瓶、连接器、触发器、浮袋、下降拉绳的连接下,上升段外筒与下降段外筒在空中可以分离,在滑动密封杆的形状设置下,使得上升拉绳在拉动滑动密封杆后,滑动密封杆的下部分与隔板产生间隙,同时滑动密封杆的横段能够挤压水室内的水通过间隙排出,与触发片接触,从而打开阀门,将二氧化氮气瓶内的气体充入浮袋内,使得浮袋膨胀撞击连接筒二,给连接筒二推动力,使得上升段外筒与下降段外筒分离,连接筒二内的下降拉绳被拉出,使得救生弹头具有被二次推动进行飞行,进而提高设备的抛投距离。
