High-pressure mooring outer wall maintenance unmanned aerial vehicle

The invention relates to the technical field of unmanned aerial vehicles, in particular to a high-pressure mooring outer wall maintenance unmanned aerial vehicle which comprises a supporting plate, two short arms, two supporting arms, a supporting rod, a plurality of propellers, a foot stool, a power supply unit, a feeding unit, a plurality of nozzles, two millimeter wave radars, a visual sensor and a laser radar. After an outer wall maintenance site is reached, a feeding unit provides spraying liquid, the liquid is sprayed out through a nozzle, the outer wall is maintained and cleaned, the minimum distance value of the wall body can be sensed by means of a millimeter wave radar, obstacle avoidance is implemented, the operation quality can be evaluated through a visual sensor, and the geometrical shape of the wall surface can be sensed by means of a laser radar. Under the action of the millimeter-wave radar and the laser radar, the system has high application scene adaptability and can be used for operation o
