Furthermore, the vibration generated when the drone takes off can be avoided from affecting the survey camera, preventing the survey effect from being affected, and improving the practicability of the device. By setting the cleaning component 8, when high-altitude moisture adheres to the surface of the survey camera 7, under the combined use of the electric push rod 85, the rack plate 86, and the sector gear 84, the cleaning brush strip 81 deflects around its connection with the survey camera 7. At this time, the moisture attached to the survey camera 7 can be cleaned up, eliminating the need for personnel to land the drone again for cleaning, avoiding waste of working time, and further improving the practicability of the device. It solves the problems that the drone will generate vibration during use, the vibration will cause the survey camera to shake, affecting the survey effect. Secondly, when encountering relatively humid weather at high altitude, the moisture will adsorb on the camera, making the camera unable to clearly capture the survey image, and when cleaning, personnel still need to land the drone again for cleaning, consuming a lot of time of the personnel.
