METHOD OF EXTINGUISHING FIRES WITH MULTIFUNCTIONAL ROBOTIC SYSTEM IN CASE OF ACCIDENTS IN TUNNELS Russian patent published in 2025 - IPC A62C3/02 A62C37/00 A62C31/02 A62C27/00 G08B17/00 A62C35/58 

FIELD: fire-fighting equipment.

SUBSTANCE: invention relates to fire extinguishing and specifically to a method of extinguishing fires with a multifunctional robotic system in case of accidents in tunnels. Method comprises starting a fire alarm system of an automatic fire extinguishing installation, which includes a control device, a pump station, program-controlled or oscillating shafts arranged on a fire pipeline; supply of jets of fire extinguishing substance, scanning in vertical and horizontal planes, at that, fire localization is performed by automatic fire extinguishing installation; program-controlled or oscillating shafts are installed at distance of compact jets from each other on 2 sides of tunnel along transport tunnels above vehicles; each program-controlled or oscillating shaft is equipped with an electric lock; fire zone is determined using address fire alarm, with transmission of information to a control device, which sends a signal to activate the pumping and opening of 2 electric valves with program-controlled or oscillating shafts located in the middle part of the fire zone from 2 sides; fire extinguishing agent jets are supplied in the range of compact jets in the form of polydisperse sprayed jets and irrigation is carried out with program-controlled barrels according to the scanning program with line jets or oscillating shafts at preset scanning angles, taking into account the protected surface of vehicles and tunnel walls irrigation; fire extinguishing is carried out with a mobile robotic system, which includes mobile robotic fire extinguishing installations, a modular compression fire extinguishing installation with water and a foaming agent for supplying compression foam, fire monitors with manual and remote control and oscillation, as well as generators with lighting projectors, video and thermal imaging systems for reconnaissance and rescue operations.

EFFECT: fire extinguishing in case of accidents in tunnels with efficient use of technical means and fire extinguishing substance with reduction of fire extinguishing time.
