Description

A drone used for fighting forest fires Technical Field

[0001] This utility model relates to the field of drone firefighting technology, and in particular to a drone used for forest fire fighting. Background Technology

[0002] In forest fire fighting, traditional methods mainly rely on firefighters carrying fire extinguishing equipment to carry out close-range firefighting operations. It is difficult for firefighters to reach complex terrain areas such as cliffs and steep slopes, and the fire intensity can change at any time with the wind direction, which brings great difficulty and danger to fire fighting. Nowadays, the use of firefighting drones in forest fire fighting is becoming more and more widespread. However, forest fires are characterized by multiple fire points, small initial fire intensity, and difficulty for personnel to reach them. Therefore, it is particularly important to know how to enable a single drone to quickly reload water and accurately dump it multiple times. Summary of the Invention

The control device automatically releases the suspension ropes on two adjacent release devices, causing the water tank to quickly tip over when subjected to a downward force. Thus, the control device can precisely control the release of the suspension ropes on the hooks of the release devices, enabling accurate water delivery from the water tank and improving fire fighting effectiveness. In practice, the drone, carrying a water tank filled with water, quickly flies to the forest fire site. The operator, based on the fire situation, precisely controls the release of the suspension ropes on the release hooks of the release devices, causing the water tank to quickly tip over at a predetermined position, accurately delivering water to the fire source. After multiple deliveries, the fire is effectively controlled, significantly improving fire fighting efficiency, while simultaneously preventing personnel from directly entering the danger zone, ensuring personnel safety.
