COMPLEX PLANT FOR FIRE EXTINGUISHING Russian patent published in 2019 - IPC A62C27/00 

FIELD: fire safety.

SUBSTANCE: invention relates to firefighting and rescue equipment for fire extinguishing and is intended for creation of water jet having high efficiency of action, as well as for provision of emergency rescue equipment with compressed air. Integrated fire extinguishing installation comprises a drive mechanism connected via a controlled clutch to a double-flow hydraulic pump connected to the hydraulic tank and connected via a liquid line to the hydraulic motor of the water pump drive connected in series through the check valve, the first valve, a metering device and an additional electric pump with foam tank having a filler neck, and through a second valve and a water intake filter connected to a water tank equipped with a first pressure gauge, the filler neck of which has a filling filter, and water pump outlet is connected in series through second pressure gauge, third valve, check valve, water flow regulator and fourth valve with flow mixer, which is three coaxially located cylinders, on ends of which there are inlet and outlet perforated flanges, wherein external cylinder is solid, inner cylinder for water supply is made with perforation, and the middle cylinder for air supply is also made with perforation with possibility of overflow of water and air flows and formation of fine air-water mixture when passing through the outlet perforated flange, wherein between the inner and middle cylinders formed by the first flow mixing circuit, and between middle and outer cylinders there is a second flow mixing circuit, wherein the flow mixer is equipped with a taper nozzle for increasing the output flow speed and successively connected along the stationary hose line through the flap valve with the stationary gun, as well as with comb equipped with three gates with first threaded heads having covers, with possibility of connection of each of them with three-way splitter, connected to working hose lines, to which is connected at least one portable gun and at least one portable hand barrel, as well as connected through a valve and a second threaded head having a cover and equipped with a first four-way splitter, each of which outputs is connected by means of the first main hose line with three-way splitter with possibility of its connection with working hose lines connected to at least one portable gun and at least one portable hand barrel, and the double-flow hydraulic pump is connected via an overhead line to the air compressor drive hydraulic motor, the air filter and the air intake, wherein the air compressor through the third pressure gauge is connected to the receiver, to which on the one hand through the second air valve is connected rescue equipment, and on the other side of the receiver through the third air valve, check valve and air flow regulator is connected to the flow mixer.

EFFECT: disclosed invention improves efficiency of fire extinguishing due to reduction of water consumption by creation of flow of finely dispersed air-and-air mixture, as well as due to possibility of elimination of fire centres simultaneously on several remote and hard-to-reach ignitions.
