Electric overhead low-voltage line fire-extinguishing unmanned aerial vehicle

Abstract

The invention relates to an electric overhead low-voltage line fire-extinguishing unmanned aerial vehicle, which comprises an unmanned aerial vehicle main body, a bracket table, an electric rotation table, a three-freedom-degree parallel connection mechanism and a fire extinguishing device, wherein the bracket table is positioned at the center position of the upper end of the fire extinguishing device, and has a Y type structure, the lower end of the bracket table is fixedly connected to the fire extinguishing device, the upper end of the bracket table is connected to the lower end surface ofthe electric rotation table, the three-freedom-degree parallel connection mechanism is positioned between the electric rotation table and the unmanned aerial vehicle main body, the lower end of the three-freedom-degree parallel connection mechanism is connected to the upper end surface of the electric rotation table, and the upper end of the three-freedom-degree parallel connection mechanism is connected to the unmanned aerial vehicle main body. According to the present invention, the electric overhead low-voltage line fire-extinguishing unmanned aerial vehicle can perform high-altitude fire-fighting and fire-extinguishing operation during the fire disaster of overhead transmission lines, has characteristics of high automation degree, stable and flexible flight during fire-fighting, largefire-fighting range, high fire-fighting efficiency and high safety, and solves the problem of high risk in the artificial fire-fighting and fire-extinguishing of overhead transmission lines.

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
