FIELD: fire-fighting means.
SUBSTANCE: method includes device of mesh screen and supply along it of protecting veil in form of film flow of cooling agent from nozzle mounted over screen, installed above zone of vitally important organs of fire robot control, screen surface is covered with black paint from external surface, and from internal surface - with foam-forming fire-proof paint, before supplying cooling agent from autonomous feeder thickener is introduced into it, and after supply of cooling agent, cooling agent flowing from screen is collected for its further use after purification in autonomous feeder. In case of abnormal development of fire and appearance of surface without protecting veil in local zones or on the whole screen, continuous foamed heat-insulating layer is formed from internal side of screen in zones of its intensive heating from external side. After use of the whole supply of cooling agent in autonomous feeder, it is discharged in place, which does not prevent robot from unimpeded movement. Device contains screen, made in form of frame, on which cloth is stretched, and means of supplying cooling agent onto screen, additionally it contains means for mixing cooling agent with thickener, made in form of balloon, connected via a valve with autonomous feeder, and closed system for re-use of cooling agent, which includes mounted on frame perimetre tray for collection of flowing from screen cooling agent and system of pipelines for further supply of the latter through system of filters into autonomous feeder. Site for autonomous feeder is made collapsible with possibility of axial turning to the side opposite to main direction of robot movement.
EFFECT: invention ensures reflection and absorption of ray energy, emerging in the vicinity of fire centre.
