Modularized aerial-launched forest fire extinguishing bomb

The modularly designed forest fire extinguishing bomb enables a dual fire extinguishing mode when the fire source is not accurately deployed, and improves the flight stability of the drone. This solves the problems of low fire extinguishing efficiency and flight instability in existing technologies, ensuring efficient fire extinguishing and safe flight in complex environments.

AI Technical Summary

Technical Problem

Existing forest fire extinguishing bombs have low fire extinguishing efficiency when the fire source is not accurately placed, and drones are unstable in forest environments and are easily affected by fire sources.

Method used

The modular forest fire extinguishing bomb includes a bag for storing extinguishing agent and a control mechanism. It features dual fire extinguishing modes, achieving directional spraying and full-coverage fire extinguishing through the detonation tube and pointed tip design. The retraction mechanism shortens the connection length between the drone and the bag, improving flight stability.

Benefits of technology

This ensures that fire extinguishing bombs can effectively extinguish fires regardless of the throwing accuracy, improving fire extinguishing efficiency and fault tolerance, and enhancing the flight stability and safety of drones in complex environments.

Abstract

The invention relates to a modularized aerial throwing forest fire extinguishing bomb, and relates to the technical field of fire extinguishing bombs, the modularized aerial throwing forest fire extinguishing bomb comprises a main body mechanism, a control mechanism and a retracting and releasing mechanism, and has double fire extinguishing modes, when a cloth bag is not precisely thrown to a fire source, part of a dry powder fire extinguishing agent is directionally shot to the fire source from a notch through the control mechanism for fire extinguishing; then the whole cloth bag is completely exploded, possible re-ignition points and splashing sparks in the peripheral area are thoroughly extinguished, it is ensured that the device can be started to effectively extinguish fire regardless of the throwing precision, and through the synergistic effect of the main body mechanism and the connecting mechanism, a pull rope is automatically wound around a winding roller in the flying process; the connecting length between the unmanned aerial vehicle and the cloth bag is effectively shortened, the swing amplitude of the cloth bag in flight is reduced, the flight stability and controllability of the unmanned aerial vehicle in the forest environment with dense forest trees and limited space are improved, the overall connecting length is reduced, the adaptability of the system to complex terrains is enhanced, and it is ensured that a fire extinguishing task is safely and efficiently executed.
