A fire-extinguishing device contains the transport vehicle with the smoke tract, the water reservoir, the water pump, and the water supplying pipes. To increase the efficacy and extend the scope of application, the device contains the second transport vehicle with the smoke tract, the water reservoir, the water pump, and the water supplying pipes. The second vehicle contains at least two smoke balloons with the bases attached to the vehicle and the gas lines for connecting the balloons with the smoke tracts. The water-supplying devices are connected with the bases of the smoke balloons. The water pipes connect the water supply device with the water pumps. |
