AI Technical Summary

Technical Problem

Existing firefighting drones use fixed-wing or non-foldable structures, resulting in large lateral dimensions that make it difficult for them to pass through narrow entrances such as doors, windows, and corridors. The wings need to be disassembled and reassembled manually, which seriously delays the opportunity for reconnaissance.

Method used

Design a fire-fighting loudspeaker reconnaissance lighting drone, which uses detachable components to connect the arms. The arms can automatically retract and extend through the adjustment mechanism and guide rail assembly. Combined with the drive assembly and guide rail assembly, it ensures that the drone can pass through narrow passages and quickly extend to the working length in narrow areas.

Benefits of technology

It enables the automatic retraction and rapid deployment of drones in narrow passages, avoiding the need to disassemble the wings, ensuring that flight stability is not affected, improving information acquisition efficiency and emergency command transmission speed, and adapting to the reconnaissance needs in narrow environments.

Abstract

The utility model relates to a fire-fighting propaganda, investigation and illumination unmanned aerial vehicle, and aims to solve the problems that a conventional fire-fighting unmanned aerial vehicle generally adopts a fixed-wing or non-foldable structural design, so that the conventional fire-fighting unmanned aerial vehicle is large in transverse size and difficult to pass through narrow entrances such as doors and windows, corridors and the like, and when entering a building, the fixed-wing unmanned aerial vehicle needs to be assembled again after wings are manually disassembled, so that the working efficiency is high. The unmanned aerial vehicle comprises a vehicle body, four vehicle arms with propellers are evenly distributed on the peripheral side of the vehicle body, and a cover plate is connected between the tops of the four vehicle arms through detachable assemblies. According to the unmanned aerial vehicle, before entering a narrow roadway, a door and a window, the vehicle arm is shortened to reduce the transverse size, the unmanned aerial vehicle can easily pass through a narrow channel, compared with a fixed-wing unmanned aerial vehicle, the step of disassembling wings is omitted, and the investigation opportunity is prevented from being delayed.
