Abstract

This invention discloses a heavy-duty hoisting firefighting drone, including a hoisting drone assembly. The hoisting drone assembly has a fire extinguishing liquid storage tank assembly and a positioning clamp assembly at its bottom center. The fire extinguishing liquid storage tank assembly is fixed to the bottom of the hoisting drone assembly in a positioning manner via the positioning clamp assembly. Multiple clamp plates simultaneously retract and abut against each other, fixing the tank neck below the drone body. Simultaneously, the simultaneous retraction of the clamp plates fixes the center of the tank neck to the center of the drone body, achieving positioning fixation. A locking component is provided on one side of the positioning clamp assembly to lock the clamp structure. A multi-stage fire extinguishing arm assembly is provided on one side of the bottom of the hoisting drone assembly. The fire extinguishing distance is adjusted by the multi-stage extension of the fire extinguishing arm assembly, and the fire extinguishing nozzle is rotated by a drive motor, achieving adjustment of the fire extinguishing nozzle's fire extinguishing angle.
