MOBILE PULSE MULTIPLE DRY POWDER FIRE EXTINGUISHING INSTALLATION Russian patent published in 2011 - IPC A62C27/00 A62C3/02 

FIELD: fire-fighting means.

SUBSTANCE: invention refers to fire-fighting equipment, namely to mobile pulse dry powder fire extinguishing installations. The installation comprises a bed plate (1), a cartridge (2). Dry powder fire extinguishing nozzle units (4) are installed in guide rails (3) of the cartridge (2). The bed plate (1) is coupled with the cartridge (2) by a rotary axis (5) that enables tilting the cartridge in a vertical plane to be fixed through a rodding (6). A portion of a smaller diametre (7) of each nozzle unit (4) is overlapped by a braking membrane (8). Each nozzle unit (4) is equipped with an electrical connector (9). Each nozzle unit (4) contains a chemical powder (10), a replaceable gas generator (11) fixed in a body portion of a greater diametre and coupled with the electrical connector. The gas generator (11) has formed holes (12) for powder (10) aeration.

EFFECT: design of the simple to operate installation allows higher effectiveness of fire extinguishing, enhanced and usability, wider range of application as provided by existing requirements due to conditioning avoiding dry chemical flow disintegration and fast speed loss, maintaining practically continuous operating conditions of fire extinguishing by minimising loss of reloading time with simultaneously increasing functional outcome reliability and installation portability as a whole.
