The present invention relates to the field of unmanned aerial vehicles, and discloses a fixed-wing fuel-cell unmanned aerial vehicle for plant protection. The fixed-wing fuel-cell unmanned aerial vehicle comprises a fuselage baseplate, a fuselage, a nose, a front frame, wings, a rear frame and empennages. A hydrogen cylinder, a fuel cell, a direct current converter, an electronic governor, an accumulator and a controller are sequentially mounted on the fuselage baseplate. The hydrogen cylinder is fixed to the fuselage baseplate through a hydrogen cylinder base; the fuel cell is connected with the hydrogen cylinder through a hydrogen pipeline, and the output end of the direct current converter is electrically connected with the accumulator, the controller and the electronic governor through a wire after being subjected to voltage conversion by the direct current converter; a pesticide box is arranged below the fuselage and connected with a water pump through a pipeline; and the outlet of the water pump communicates with multiple nozzles through a multi-pass joint and a pipeline. After the fixed-wing fuel-cell unmanned aerial vehicle for plant protection is started, the accumulator is cut off, the fuel cell supplies power for each piece of equipment of the system independently, the flight time is long, the spraying efficiency is high, and cleanness, environmental protection, safety and stability are realized.
Description
Technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a fixed-wing fuel cell plant protection unmanned aerial vehicle. Background technique [0002] The drones in the prior art include a fuselage, a rotor, and a camera pan / tilt. At the same time, the fuselage is also equipped with a flight control system. The drone is used for agricultural, forestry and plant protection operations. It is controlled by ground remote control or GPS. To realize the spraying operation, the existing drones generally use lithium batteries to supply power. The battery needs to be replaced every 15 minutes on average. The battery life is poor, which makes the drones have many battery replacements during the operation and the operation is troublesome, resulting in spraying. Low efficiency is a major defect in the popularization and application of existing plant protection drones, and further improvements are still needed in actual engineering applications....
