Rocket type line-throwing life-saving device

Abstract

The invention discloses a rocket type line-throwing life-saving device. The rocket type line-throwing life-saving device comprises a throwing barrel, wherein the throwing barrel is arranged on a bracket; a bottom sealing head is arranged at the lower part of the throwing barrel; one end of the bottom sealing head is connected with a chassis, and the other end of the bottom sealing head is provided with threads and is connected with a pressure chamber by the threads; the pressure chamber is connected with the throwing barrel by the threads; a flight body is arranged in the throwing barrel; the bottom sealing head is provided with a through hole; a flue gas chamber component is inserted into the hole and is screwed by a front nut and a rear nut; the throwing barrel is also provided with a line head fixing point. The rocket type line-throwing life-saving device disclosed by the invention has the advantages that since the high pressure generated by explosion of a propelling agent is adopted, the flight distance of the flight body is increased, and the rescue distance is increased from less than 100M to 3-4KM; the rescue difficulty is lowered and the rescue efficiency is improved; the throwing angle can be adjusted by an arranged angle disc; the throwing distance can be accurately measured by a laser distance measuring instrument.

Description

technical field [0001] The invention belongs to water lifesaving equipment, in particular to a rocket-type throwing rope lifesaving device. Background technique [0002] In maritime rescue activities, life-saving ropes are often used, which can be carried out by manual throwing in a short distance. Long-distance throwing ropes need to be assisted by equipment. The existing life-saving ropes thrown by the rope-throwing machine using compressed air as the power source Less than 100M, the scope of rescue is limited. Contents of the invention [0003] In order to overcome the shortcoming of the short throwing distance of the existing rope throwing equipment, the object of the present invention is to provide a rocket type throwing rope life-saving device that can throw the rope at a long distance and increase the rescue range. [0004] The object of the present invention is achieved in the following way: A rocket-type rope-throwing life-saving device includes a projecting tube...
