US 9,345,914 B1 · Automatic fire extinguishing system

Abstract

The automatic fire extinguishing system is installed in one or more rooms of a building structure or the like. A track is installed along the inner perimeter of the wall of the room(s), near the ceiling. A mobile fire extinguishing module travels along the track. The fire extinguishing module includes a supply of fire extinguishing agent, a directionally controllable dispensing nozzle, a drive motor for at least one wheel, and a receiver and controller. A number of smoke and/or fire detectors is installed in the room, with the detectors communicating wirelessly with the receiver and controller of the module. A signal received by the module from an activated detector results in the module traveling to the location nearest the activated detector, whereupon a valve is opened to dispense the fire extinguishing agent. A secondary module may be provided, with the primary module automatically connecting to the secondary module when required.

Dependent claims

An automatic fire extinguishing system for a building structure, the system comprising:

an endless track disposed within the building structure;
a primary mobile fire extinguishing module disposed upon the track;
a detector receiver and module controller disposed in the module;
a plurality of smoke and fire detectors disposed within the building structure, at least one of the smoke and fire detectors communicating with the detector receiver of the module when the at least one of the detectors is actuated;
a selectively movable agent dispensing nozzle disposed upon the module;
an infrared sensor disposed with the nozzle;
a first gimbal ring disposed about the nozzle, the first gimbal ring having a first axis;
a first gimbal drive motor communicating with the first gimbal ring;
a second gimbal ring disposed between the nozzle and the first gimbal ring, the second gimbal ring having a second axis orthogonally disposed relative to the first axis;
and
a second gimbal drive motor communicating with the second gimbal ring, the infrared sensor directing the first and second gimbal drive motors for aiming the nozzle.
