METHOD TO EXTINGUISH FIRE IN WATERCRAFTS Russian patent published in 2016 - IPC A62C3/00 

FIELD: fire safety.

SUBSTANCE: invention relates to fire-fighting means. Method consists in fact that when making watercrafts, hollow air ducts are made in their walls, connected to compressed air receiver, which is connected to compressor. In zones of maximum fire hazard, openings with tight covers are made in hollow air ducts, which are opened by reversing electromagnetic drive in case of fire in those zones. In each window with tight cover vessel with fire extinguishing substance is set, equipped with siphon tube and air nozzle, connected to hollow air duct via pulse valve and intended for producing repeated short-time blast exhausts of compressed air with fire extinguishing substance dispersed in portions therein. In each window temperature sensor is set, emitting signals towards fire extinguishing control unit in case of fire, or in case of its termination. By signal of temperature sensor, cover of said window is opened using reversible electromagnetic valve. Flame from burning objects is whipped, and poured with dispersed portions of fire extinguishing medium.

EFFECT: proposed invention provides improving efficiency and responsiveness of fire extinguishing.
