Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle inspection, in particular to a rain and dust proof device for unmanned aerial vehicle inspection. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer.

[0003] After searching the patent document with the announcement number CN220448165U, the patent document discloses "a rain and dust proof device for unmanned aerial vehicle inspection, which cooperates with the adjustment component, the protective cover and the camera. When in use, the adjustment component drives the two sets of protective covers to move relative to each other on the surface of the camera, so that the two sets of protective covers merge with each other to cover the camera to prevent rain from splashing on the camera and causing damage. The rotation of the rotating component drives the rotating plate to rotate, and the rotation of the rotating plate drives the arc sponge to rotate on the surface of the camera lens, so that the arc sponge wipes the dust on the surface of the lens, preventing a large amount of dust from adhering to the surface of the lens and affecting the subsequent image acquisition";

[0004] The above-mentioned device drives the rotating plate to rotate through the driving device, so that the rotating plate cleans the outer surface of the camera lens. Combined with the protective structure, the above-mentioned device can be suitable for rainy days and windy and sandy environments. There are some relatively hard small particles in the wind and sand. If these small particles adhere to the lens of the camera, these relatively hard small particles may scratch the lens when the rotating plate cleans the lens, which may easily affect the pictures taken by the camera inspection.
