FIRE-FIGHTING PUMPING-HOSE SYSTEM Russian patent published in 2020 - IPC A62C31/00 A62C31/24 A62C31/28 

FIELD: fire safety equipment.

SUBSTANCE: in a fire-fighting pumping-hose system, comprising a pressure fire hose, connection heads, stopcocks and means for supplying water or extinguishing substance under pressure to a fire point through detachable metal nozzles. Pressure fire hose is made of 2–10 adjacent sections, between connecting heads of which there is distribution unit with mating connecting heads and support platform made of fire-resistant structural material, in the middle part of the distribution unit perpendicular to the axis there is a bend in the form of a transient straight or L-shaped fitting with a shut-off valve and a connection head for connection of a side branch in the form of a pipeline flexible in its main part from fire-resistant material with a nominal diameter smaller than the diameter of the pressure fire hose, to supply water to the ignition centers remote from the distribution unit through a replaceable nozzle in the form of an atomizer or drencher sprayer arranged on the end of the flexible pipeline, wherein the outlet in the middle part of the distribution unit is configured to turn on the angle set by the fire-extinguishing conditions with subsequent fixation in the plane perpendicular and / or parallel to the axis of the distribution unit, first section of pressure fire hose is connected through auxiliary fire hose and main sleeve branch to main hose line, at end of last section of pressure fire hose there is an end distributing unit with end plug and branch for connection of side branch of specified type, and support platform base is equipped with at least one device for platform attachment to horizontal, inclined or vertical surface of fire extinguishing facility.

EFFECT: technical result of the invention consists in improvement of efficiency of fire extinguishing, expansion of functional capabilities and reduction of time for liquidation of fire centers by fire calculations in complex conditions of fire extinguishing in buildings and structures.
