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

Embodiment 1

[0057] A collision-resistant four-rotor spherical UAV system, such as Picture 10 As shown, it includes a flight platform 001 for performing flight tasks, a task load 002 carried on the flight platform 001 for detection, and ground equipment for remote control, telemetry, and data transmission of the flight platform 001 or the task load 002.

[0058] Such as Figure 1-Figure 5 As shown, the flying platform 001 includes a spherical frame mechanism 1, an aircraft body 3 completely located inside the spherical frame mechanism 1, and a supporting mechanism 2 that connects the spherical frame mechanism 1 and the aircraft body 3 into an integral body.

[0059] The spherical frame mechanism 1 as a whole is in the structure of the latitude and longitude frame of the globe. The supporting mechanism 2 includes an annular connecting piece located in the center of the spherical frame mechanism 1 and two supporting tubes 204 respectively arranged along the rotation axis of the globe. The annular...

Embodiment 2

[0064] In this embodiment, the structure of the flight platform 001 is further optimized on the basis of embodiment 1, such as Figure 1-Figure 4 As shown, the flying platform 001 is mainly composed of a spherical frame mechanism 1, an aircraft body 3, and a supporting mechanism 2 that connects the spherical frame mechanism 1 and the aircraft body as a whole. The spherical frame mechanism 1 and the supporting mechanism 2 together form a spherical protective structure that protects the aircraft body 3, improves the collision resistance of the entire flying platform 001, and effectively protects the aircraft body 3 to fly safely in a complex environment. The mission load 002 is integrated on the aircraft body 3 for easy disassembly and maintenance.

[0065] In this embodiment, the specific structure of the spherical frame mechanism 1 and the supporting mechanism 2 is emphasized, and the principle that the spherical protective mechanism makes the aircraft body 3 resistant to collisi...

Embodiment 3

[0084] In this embodiment, on the basis of Embodiment 2, the material of the spherical frame mechanism 1 is further optimized. Such as Figure 5 As shown, the latitude ring frame 101 is a complete ring-shaped carbon fiber sheet; the longitude ring frame 102 is composed of four fan-ring carbon fiber sheets spliced ​​together; the longitude tube 103 is a glass fiber stringer; the bearing seat 104, The bearings 105 are all lightweight plastics; the end faces of the bearing housing 104 are respectively fixed with the glass fiber stringers passing through the annular carbon fiber sheet and the fan-ring carbon fiber sheet fixed on the annular carbon fiber sheet at one end. Each additional circular latitude circle is composed of four fan-ring carbon fiber sheets, or each additional circular latitude circle uses one end-to-end looped glass fiber stringer, or the additional circular latitude circle part uses four fan-ring carbon fiber It is composed of splicing thin slices and partly co...

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...
