HIGH-SPEED AUTOMATIC FIRE EXTINGUISHING SYSTEM Russian patent published in 2021 - IPC A62C37/08 

FIELD: fire safety.

SUBSTANCE: invention relates to fire-fighting equipment and can be used in industrial and civil facilities with an increased fire hazard to localize fire beds and for surface or local-surface extinguishing with water or air-mechanical foam of fires in buildings, structures and open technological sites at objects of the 1st hazard class, in particular at the flammable polymer and pyrotechnic product manufacturing facilities. The automatic fire extinguishing system contains a pipeline for supplying the extinguishing agent, means of distributing the extinguishing agent over the zones of possible ignition or fire with shut-off and starting devices, the shut-off and starting devices are made with electromagnetic drives with the possibility of automatically opening the outlets of the extinguishing agent from the means of distributing the extinguishing agent according to the signal of ignition or fire detectors and contain permanently installed electromagnetic locks with lock anchors, pivotally installed and drawn to the anchors of the locks by magnetic forces when electric current is applied to the electromagnetic locks, the clamping bars and clamps mated with the clamping bars with plugs for the outlets of the extinguishing agent from the means of distribution of the extinguishing agent, made with the possibility of opening the outlets of the extinguishing agent from the means of distributing the extinguishing agent by removing the plugs from the outlets of the extinguishing agent from the means of distributing the extinguishing agent when the clamping bars are released from the attracting magnetic forces at the moments of automatic opening of the electromagnetic locks by the signals of the fire detectors.

EFFECT: increased efficiency of fire extinguishing.
