Description

Technical Field

[0001] This utility model relates to the field of aerial cleaning technology, and in particular to a laser cleaning drone. Background Technology

[0002] Currently, the general method for drone laser cleaning is as follows: The drone first takes off and hovers over the solar photovoltaic panel. Then, it uses onboard sensors or navigation to locate itself. Next, its onboard camera scans and identifies the stains that need cleaning. Once the cleaning location is determined, the drone's laser cleaning system begins operation, using pulsed lasers to ablate the stains. Subsequently, the onboard camera performs a second scan of the solar photovoltaic panel surface to check if the cleaning has achieved its intended purpose. If not, a second cleaning cycle is performed until the cleaning is complete. Afterward, the drone lands in a safe area.

[0003] In this approach, the laser ablation range is limited, and the resulting ash places a significant burden on work efficiency. Utility Model Content
