Abstract

The invention provides a variable-axisbase unmanned aerial vehicle mechanism with a fire extinguishing launch device, including a transmission assembly, an arm assembly, a launch assembly, and a wing assembly; the arm assembly includes a crank rod, an upper joint, a carbon tube, and a connecting rod , lower joint, Y-shaped connecting rod, and round nut. The curved rod, upper joint, carbon tube, connecting rod, lower joint, and Y-shaped connecting rod form a parallelogram, and the height of the parallelogram is changed under the drive of external force to drive The wings always swing up and down parallel to the horizontal plane.

Description

technical field [0001] The invention relates to a fire-fighting unmanned aerial vehicle technology, in particular to a variable wheelbase unmanned aerial vehicle mechanism with a fire-extinguishing launching device. Background technique [0002] Multi-rotor drones have the characteristics of zero casualties, few restrictions on use, good concealment, and high cost-effectiveness. Their status and role in modern fire rescue are becoming increasingly prominent. The number, type and frequency of multi-rotor UAVs used for fire fighting are showing a rapid growth trend. Therefore, vigorously developing unmanned aerial vehicle-carrying fire-fighting technology has become the direction of competing research in various countries. In recent years, countries have issued their own drone development plans and increased investment, and the development of drones has shown an unprecedented upsurge. [0003] Traditional drones mainly carry fire extinguishing bombs by hanging. Therefore, t...
