Abstract

The invention discloses a firefighting device based on an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The firefighting device comprises a water tank, a booster pump, a PLC control cabinet, an electromagnetic valve and a power box for supplying power to the booster pump, the PLC control cabinet and the electromagnetic valve. The booster pump, the PLC control cabinet and the power box are all mounted on the outer top surface of the water tank, and the electromagnetic valve and the booster pump are correspondingly and electrically connected with the PLC control cabinet. A water inlet of the booster pump communicates with a water outlet of the electromagnetic valve through a pipeline, a water inlet of the electromagnetic valve communicates with thewater tank through a pipeline, and a plurality of high-pressure nozzles formed in the outer bottom surface of the water tank are connected to a water outlet of the booster pump through pipelines. Fireextinguishing operation can be carried out by sprinkling water and throwing fire extinguishing bombs at the same time, and the fire extinguishing effect is effectively improved; and the firefightingdevice is simple in structure and convenient and stable to control, application of the unmanned aerial vehicle in the field of fire extinguishing and disaster relief can be promoted and enhanced, personnel investment in the fire extinguishing personnel process is reduced, and casualties caused in the fire extinguishing process are reduced.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a firefighting device based on drones. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease ...
