A collision-resistant quadrotor spherical UAV system

Abstract

The invention discloses a collision-resistant four-rotor spherical unmanned aerial vehicle system, which includes a flight platform for performing flight tasks, a task load mounted on the flight platform for detection, and a device for remote control, telemetry, and data transmission of the flight platform or task load. ground equipment. The flying platform includes an integrally arranged spherical frame mechanism, an internal aircraft body, and a supporting mechanism. The spherical frame mechanism as a whole is in the structure of a globe latitude and longitude frame. The support mechanism includes an annular connector located at the center of the spherical frame mechanism and two support tubes respectively arranged along the rotation axis of the globe. The center of gravity of the platform is lower than the center of gravity of the ring connector. The invention provides an integrally arranged annular protection structure for the aircraft body, so that the flight platform has good collision resistance and still has strong survivability and adaptability in complex environments.

Description

Technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a collision-resistant four-rotor spherical unmanned aerial vehicle system. Background technique [0002] In recent years, my country’s civil unmanned aerial vehicles have experienced a blowout development, which is widely used in entertainment, film and television, surveying and mapping, security and other fields. Due to its flexible flight, relatively simple operation and hovering in place, multi-rotor unmanned aerial vehicles are favored by firefighters and have been increasingly used in firefighting and rescue scene investigation, monitoring, command and drawing Wait for work. [0003] Foreign fire departments have widely used drones for rescue operations. Fire departments in various countries are equipped with firefighting drones to perform reconnaissance and surveillance tasks. In March 2017, the New York City Fire Department (FDNY) used drones to assist firefighters in ex...

AI Technical Summary

Problems solved by technology

[0005] (1) Carry a visible light + infrared camera to conduct reconnaissance and surveillance of the fire scene, but can only shoot in the building and cannot enter the interior;

[0006] (2) Carry gas detectors, toxic gas detectors, temperature sensors, etc. to detect the sky over open areas and the periphery of fire areas, and cannot enter the interior

[0008] However, for this new type of equipment, the fire brigade also has some limitations in its use: the current unmanned aerial vehicles used in firefighting applications can only detect on-site conditions, gas detection, temperature detection or fire extinguishing over open areas, while in complex environments ( For fire reconnaissance under tunnels, tunnels, buildings, underground buildings, existing drones cannot enter the scene or even if they enter the scene, they are extremely vulnerable to impact and crash
