description The invention relates to a power supply wire-dragging type multi-shaft unmanned rotorcraft fire extinguishing apparatus and a fire extinguishing method and aims to solve the problem that an existing multi-shaft unmanned rotorcraft is low in effective load and short in aerial work time. The power supply wire-dragging type multi-shaft unmanned rotorcraft fire extinguishing apparatus provided by the invention comprises ground equipment, a multi-shaft unmanned rotorcraft and a power supply wire connected to the ground equipment for providing a high voltage; the unmanned rotorcraft is connected to a high pressure liquid spraying device, a high pressure nozzle of the high pressure liquid spraying device is horizontally mounted below the unmanned rotorcraft, and the upper and lower space included angel between the high pressure nozzle and the horizontal position of the unmanned rotorcraft is 0-22.5 degrees. The power supply wire-dragging type multi-shaft unmanned rotorcraft fire extinguishing apparatus has the benef
