Abstract

The invention relates to the technical field of emergency rescue, and discloses a line throwing gun for ship lifesaving and fire fighting. The line throwing gun comprises a line throwing gun cavity, a handle is fixedly installed on one side of the bottom end of the line throwing gun cavity, the center of one end of the line throwing gun cavity is fixedly connected with a gas conveying pipeline, the center of the other end s fixedly connected with a throwing pipe connector, a trigger is hinged to the handle, and a jacking rod is attached to one end of the trigger. Through a designed blocking plate, closing of an opening of the line throwing pipe is directly controlled by mechanical transmission of the trigger, the line throwing gun gets rid of original piston blocking, pressure loss caused by the fact that part of air pressure in the line throwing gun cavity is used for opening a piston is avoided, and meanwhile, through a designed power spring and a designed pressurizing plate, when a blocking plate is opened, the power spring can drive the power plate to rebound to provide additional acting force for the high-pressure gas, so that the output pressure of the high-pressure gas is increased, and the throwing distance is increased.

Description

technical field [0001] The invention relates to the technical field of emergency rescue, in particular to a rope throwing gun for ship lifesaving and fire fighting. Background technique [0002] The rope-throwing gun for ship life-saving and fire-fighting is mainly a kind of rescue gun that uses gunpowder or high-pressure gas to shoot the rope end to make it fall to the person to be rescued or a fixed position. Since the ship's rope-throwing gun is mostly used on the water surface, the environment is humid This allowed most ships to use high-pressure gas instead of damp gunpowder. [0003] Existing rope-throwing guns can only be used in downwind conditions in order to obtain a longer throwing distance. However, the rescue environment is changeable. Blindly pursuing the downwind environment will often delay the rescue opportunity. At the same time, most of the existing rope-throwing guns use pistons. Block the air outlet, and after the trigger is pulled, the internal high-pr...
