FIELD: fire fighting service; methods and equipment for the automatic pulsing fire extinguishing 2004106871/12 (54) Method of the automatic pulsing fire extinguishing. ^ SUBSTANCE: the invention is intended for utilization at the fires extinguishing, for example, the stores with the highly inflammable liquids, on the oil producing installations in the conditions of the variable forces and directions of the wind in the area of the fire. The technical result of the invention is the increased reliability and the reduced inertia at the fires extinguishing process in the pulse operation, including the case of the initial stage of inflammation, irrespective of the direction and the strength of the wind, the increased processibility index, the decrease of the complication and the cost of the system. The technical result is reached by that the method provides for the feeding by the system of the installations into the zone of the fire of the fire extinguishing composition. The direction of feeding of the fire extinguishing composition by the installations is set with consideration of the direction and speed of the wind at the moment of inflammation according to the information coming from the weather vane. At that the direction of the possible feeding change in advance with per second corrective action of the position of the barrel device before origination of the inflammation. The method is realized by the system including the fire extinguishing pulsing installations, each of which has the infrared sensor, the barrel device supplied with the charge of the fire-extinguishing composition with the pyrocartridge. The infrared sensor is mounted fixed with the capability to control the preset sector of fire extinguishing, and the barrel device is made with the capability of correction of its position in the horizontal plane and is supplied with the rotation driving gear in the form of the electromotor with the worm reduction gearbox connected through the matching unit with the control unit. At that the control unit is connected with the infrared sensor, the pyrocartridge and the reading device of the weather vane mounted in the zone of the installations. ^ EFFECT: the invention ensures the increased reliability and processibility of the method and the of the pulsing fire extinguishing system, reduced inertia at the fire extinguishing process, complication and the cost of the system. ^ 2 cl, 1 dwg |
