A fire-fighting drone for overhead low-voltage lines

Abstract

The present invention relates to a fire extinguishing unmanned aerial vehicle for electric power overhead low-voltage lines, which includes a main body of the unmanned aerial vehicle, a support platform, an electric turntable, a three-degree-of-freedom parallel mechanism and a fire extinguishing device; the support platform is located at the center of the upper end of the fire extinguishing device, and the support platform It is a "Y" structure, the lower end of the support platform is fixedly connected with the fire extinguishing device, the upper end of the support platform is connected with the lower end surface of the electric turntable, the three-degree-of-freedom parallel mechanism is located between the electric turntable and the main body of the drone, and the lower end of the three-degree-of-freedom parallel mechanism is connected to the The upper end faces of the electric turntable are connected, and the upper end of the three-degree-of-freedom parallel mechanism is connected with the main body of the drone. The invention can carry out high-altitude fire-fighting and fire-extinguishing operations when a fire occurs on overhead transmission lines, and has high automation, stable and flexible flight during fire-extinguishing, large fire-extinguishing spray range, high fire-extinguishing efficiency and high safety, and solves the danger of manual fire-fighting and fire-extinguishing of overhead transmission lines Big question.

Description

technical field [0001] The invention relates to the field of electric fire-fighting aircraft, in particular to an electric overhead low-voltage line fire-fighting unmanned aerial vehicle. Background technique [0002] Electricity is an energy powered by electric energy. It was invented in the 1870s. The invention and application of electric power set off the second industrialization climax and became one of the three scientific and technological revolutions in the world since the 18th century in human history. Since then, technology has changed people. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. The primary energy is converted into electricity through mechanical energy devices, and then the electricity is suppli...

Problems solved by technology

[0004] For fire-fighting and fire-fighting methods, manual fire extinguishers are often used to enter the fire-fighting scene for manual fire-fighting operations. For low-altitude fires, elevators are often used to send firefighters to high places for fire-fighting operations. Such existing fire-fighting methods are dangerous and pose a threat to firefighters. Personal safety poses a great threat. Every year, many firefighters die because of on-site fire-fighting operations. At the same time, the fire-fighting efficiency of manual on-site fire-fighting operations will gradually decrease as the operating time increases, and the overall fire-fighting efficiency is low. , slow speed and poor flexibility
