Unmanned aerial vehicle for firefighting of power transmission line

Abstract

The invention relates to an unmanned aerial vehicle for firefighting of a power transmission line. The unmanned aerial vehicle comprises an unmanned aerial vehicle body, a support table, an electric rotary table, a Stewart parallel-connection mechanism and a fire extinguishing device, wherein the support table is located in the center position of the upper end of the fire extinguishing device, and is of a Y-type structure; the lower end of the support table is fixedly connected with the fire extinguishing device; the upper end of the support table is connected with the lower end face of the electric rotary table; the Stewart parallel-connection mechanism is located between the electric rotary table and the unmanned aerial vehicle body; the lower end of the Stewart parallel-connection mechanism is connected with the upper end face of the electric rotary table; and the upper end of the Stewart parallel-connection mechanism is connected with the unmanned aerial vehicle body. The unmanned aerial vehicle can carry out high-altitude fire extinguishing operation on the overhead power transmission line when a fire happens, the automation degree is high, the unmanned aerial vehicle is stable and flexible in flight when carrying out fire extinguishing, the fire extinguishing jetting range is wide, the fire extinguishing efficiency is high, safety is high, and the problem that danger of manual fire extinguishing for the overhead power transmission line is high is solved.

Description

technical field [0001] The invention relates to the field of electric fire-fighting aircraft, in particular to an electric power transmission 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 supplied...

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
