The photographed images are transmitted to the staff by the wireless transmission module. The drone body 1 can move independently according to the predetermined route, and the pan-tilt camera 3 takes pictures at the same time, thereby realizing intelligent hot plate inspection.

[0028] During operation, through the setting of the baffle 10, after the scraper 6 scrapes the dust on the surface of the ball cover 4, the scraper 6 can be retracted between the baffle 10 and the ball cover 4.

[0039] In summary, the motor 7 drives the driving gear 8 to rotate, so that the bevel gear 5 rotates, and the bevel gear 5 drives the scraper 6 to move along the ball cover 4. The scraper 6 rotates 180 degrees. During the rotation of the scraper 6, the dust on the surface of the ball cover 4 is scraped off, thereby preventing a large amount of dust from adhering to the surface of the ball cover 4. After the scraper 6 scrapes the dust on the surface of the ball cover 4, the scraper 6 will be collected between the baffle 10 and the ball cover 4. The baffle 10 can block sunlight and provide protection. When the dust needs to be scraped off again, the motor 7 is reversed to make the scraper 6 rotate 180 degrees to scrape off the dust on the surface of the ball cover 4. After the drone body 1 is lifted, the photovoltaic panel on the ground is photographed through the pan-tilt camera 3, so as to detect the surface temperature of the photovoltaic panel and take pictures.
