PEAT FIRE EXTINGUISHING DEVICE Russian patent published in 2022 - IPC A62C3/02 A62C31/22 

FIELD: fire engineering.

SUBSTANCE: claimed invention relates to fire engineering, namely, to a device designed for impregnating burning peat with a fire extinguishing liquid. The device comprises a barrel with a perforated tube with a tip, two hollow handles, one of which is equipped with a fitting for connecting a flexible hose with a tap that opens the supply of fire extinguishing liquid into a perforated tube with a tip, in which at least one of the rows of perforations is made at an acute angle to the axis tubes, the rest at an angle of 90°, and at least one row of holes located at an obtuse angle to the axis of the tube. The perforated tube is placed with the possibility of fixed movement along the tube axis inside the drilling nozzle, equipped with nozzles located at an acute angle and an angle of 90° to the tube axis, the axes of which are aligned with the axes of unidirectional holes in the perforated tube, and nozzles located at an obtuse angle to the tube axis , the axes of which are displaced with respect to the unidirectional holes of the perforated tube by the value of the fixed displacement, selected from the condition of complete overlapping of nozzles located at an acute angle and an angle of 90°, and opening of nozzles located at an obtuse angle. The conical tip of the perforated tube is equipped with nozzles, the barrel of the device is made telescopic, and the drilling nozzle is connected to the barrel with the possibility of rotation relative to it.

EFFECT: invention provides high efficiency of extinguishing underground peat fires, which is expressed in a greater depth of impregnation of burning peat with fire extinguishing liquid.
