FIELD: fire-fighting equipment.
SUBSTANCE: invention concerns lifting fire-fighting equipment to the required height and power supply for fire-fighting high-rise buildings. A high-rise building fire extinguishing device comprises a hose with a nozzle, an unmanned aerial vehicle (UAV) adapted to hold a fire hose. At the same time, the fire hose is structurally integrated with the electric power cable of the UAV. Moreover, the electric cable consists of two insulated current-carrying wires of different polarity, separated from each other by a flexible jumper and spaced from each other diametrically inside the fire hose. Moreover, the hose can also be structurally combined into a common flexible shell with an electric UAV power cable, consisting of two insulated current-carrying wires of different polarity, spaced from each other diametrically outside the fire hose.
EFFECT: increased reliability.
