INDOOR FIRE EXTINGUISHING DEVICE Russian patent published in 2025 - IPC A62C3/00 A62C37/00 A62C35/02 

FIELD: fire-fighting means.

SUBSTANCE: invention relates to a robotic means for fire extinguishing, specifically to a device for extinguishing a fire in a room, which comprises two H-beams (1) secured along opposite long sides of the room so that their top flanges are located at one level. Top flanges of two H-beams support identical first (3) and second (4) carriages. Across the lower part of each carriage (3 and 4) two axles are passed, on one of which a pair of driving wheels (5) is fixed, and on the other axle a pair of driven wheels (6) is fixed. Inner parts of drive (5) and driven (6) wheels are made with diameter smaller than that of their outer part and are intended for movement along upper flange of double-tee beam. Outer parts of drive (5) and driven (6) wheels cover lateral sides of upper flange of double-tee beam. Axes of driving wheels (5) of carriages (3 and 4) are respectively connected to the shaft of first (7.1) and second (7.2) electric drive, which are fixed outside on the side surface of first (3) and second (4) carriages, to the ends of which dampers are attached . Ends of transverse double-tee beam (9) are installed on top of first (3) and second (4) carriages, and the lower flange of the latter is attached to first (3) and second (4) carriages. Third carriage (10) is arranged on lower flange of crosswise beam (9) to displace thereon. Ends of two axles are attached to the inner part of the first side wall of which at the same level, on the other ends of which corresponding drive wheels (11) are mounted, part of each of which facing the first side wall of third carriage (10) is made with teeth, wherein the outer diameter of wheel part with teeth is larger than that of drive wheel part (11) with smooth outer surface for motion on the ledge of bottom flange of third double-tee beam (9). Between two gear parts of two drive wheels (11) there is the first gear wheel (12) of smaller outer diameter so that gear parts of two drive wheels (11) are engaged with it. First smaller-diameter gear (12) is fitted on the end of axle passed through sidewall of third carriage (10). Other end of axis is connected with shaft of the third electric drive (13) located in central part of side wall of third carriage (10). To inner part of the second side wall of third carriage (10) ends of two axles are attached at same level, on the other ends of which corresponding driven wheels (14) are installed. From outside to bottom of third carriage (10) end of rack (15) is welded vertically, one side of which is made with teeth. Rack (15) is passed through rectangular housing (16) open from above and from below, outside of which fourth electric drive (17) is installed, which shaft is connected to the axis passed through rectangular housing (16) front wall, inside which on the axis other end the smaller diameter second gear wheel (18) is rigidly fixed, made with possibility of engagement with rack (15) teeth. On axis, end of which is attached from inside to front wall of rectangular housing (16), idle wheel (19) is installed so that it is located between smooth side of rack (15) and side wall of rectangular housing (16). Lock ring (20) is made on free end of rack (15), to upper end of rectangular housing (16) dampers are attached. Horizontally positioned plate (21) is welded to the lower butt end, in the central part of which injector (22) is mounted into a through hole, the nozzle of which is directed vertically downwards. Inlet of nozzle (22) by pipeline (23) through solenoid valve (24) and pump unit (25) is connected to tank (26) filled with water. Sensitive element of gas analyser (27) is inserted into the second through hole near the edge of plate (21). Temperature sensor (28) and video camera (29) are attached to plate (21) from below. Fire gas detectors (32) and combined fire detectors (33) are fixed on the ceiling or on the walls of the room and are connected to the monitoring, control and programming unit (30.1) through the fire alarm loop, to which gas analyser (27), temperature sensor (28), video camera (29) and analogue-to-digital conversion unit (30.2) are connected, which is connected to the unit of functional measurements and correlations with given informative parameters (30.3). Fire gas (32) and combined detectors (33) are connected to unit of analogue-to-digital conversions (30.2). Functional measurements and correlations unit with given informative parameters (30.3) is connected to the monitoring, control and programming unit (30.1), which is connected to actuators control device (31), which is connected to first (7.1), second (7.2), third (13) and fourth (17) electric drives, to solenoid valve (24) and pump unit (25), which is connected to monitoring, control and programming unit (30.1).

EFFECT: reducing the time for extinguishing of fire source and the required water consumption for this purpose.
