The invention relates to the technical field of fire-fighting lifesaving equipment, and discloses a long-distance lifesaving throwing device and a using method thereof. The lifesaving throwing device comprises a gas cylinder cover. According to the long-distance lifesaving throwing device, the ascending section outer cylinder and the descending section outer cylinder can be separated in the air through clearance fit of the ascending section outer cylinder and the descending section outer cylinder and connection of the nitrogen dioxide gas cylinder, the connector, the trigger, the floating bag and the descending pull rope; under the shape setting of the sliding sealing rod, the lifting pull rope pulls the sliding sealing rod, and a gap is formed between the lower part of the sliding sealing rod and the partition plate; meanwhile, the transverse section of the sliding sealing rod can extrude water in the water chamber to be discharged through the gap and make contact with the trigger piece, so that the valve is opened, gas in the nitrogen dioxide gas cylinder is filled into the floating bag, and the floating bag swells to impact the second connecting cylinder to provide pushing force for the second connecting cylinder; therefore, the ascending section outer cylinder is separated from the descending section outer cylinder, the descending pull rope in the second connecting cylinder is pulled out, the lifesaving bullet obtains secondary promotion for flying, and then the throwing distance of the equipment is 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及其使用方法,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。
