Example

[0030] See also Figure 1-Figure 8 The present invention also discloses a method for power inspection based on the Internet of Things, which specifically includes the following steps: S1. When the mobile robot body 1 performs the power inspection task, it first moves in the power facility area according to the preset program or the route set by the remote monitoring center. When encountering an uneven road surface, the first motor 26 is started, and the output shaft of the first motor 26 drives the bidirectional screw 22 to rotate in the first housing 21. Since the outer wall of the bidirectional screw 22 is threadedly connected to two sliding extension plates 23, and the two sliding extension plates 23 are movably inserted into the inner wall of the first housing 21, the rotation of the bidirectional screw 22 will cause the two sliding extension plates 23 to move relative to each other in the first housing 21. The connecting plate 24 fixedly installed at one end of the outer wall of the two sliding extension plates 23 is connected to the four supporting and moving wheels 25, so that the supporting and moving wheels 25 can be extended outward. When the supporting and moving wheels 25 are extended outward, the supporting bottom surface of the mobile robot body 1 is increased, which effectively improves the stability of the mobile robot body 1 during movement and reduces the possibility of rollover due to unstable center of gravity. When it is on a normal road surface, the supporting and moving wheels 25 can be retracted inward; S2. During the mobile inspection process, the second motor 319 and the threaded screw 33 are driven to rotate, so that the panoramic camera 38 and the infrared thermal imager 39 are located outside the protective shell 31, and the panoramic camera 38 and the infrared thermal imager 39 continue to work. The panoramic camera 38 is responsible for collecting the appearance image information of the power facilities, and can clearly capture the overall shape, surface condition and surrounding environment of the equipment, etc., which can be used to detect physical damage to the equipment, foreign matter adhesion, etc. The infrared thermal imager 39 focuses on collecting thermal imaging data of the power equipment. By detecting the temperature distribution on the surface of the equipment, it can timely find the overheating fault point of the equipment, such as local overheating caused by poor electrical connection and overload operation. The two will feed back the information recorded by the inspection to the mobile robot body 1, and the mobile robot body 1 will feed back the information to the staff, so that the staff can get this information. When encountering a harsh environment and unable to conduct inspections, the second motor 319 and the threaded screw 33 drive the mobile plate 35 to descend, and the mobile plate 35 then drives the panoramic camera 38 and the infrared thermal imager 39 to descend to the inside of the protective shell 31. When the mobile plate 35 descends, , which will drive the rack 36 to move. When the rack 36 moves to contact with the gear 317, it will drive the gear 317 to rotate. The gear 317 then drives the driving wheel 318 to rotate through the rotating shaft 316. The driving wheel 318 drives the driven wheel 314 to rotate through the belt 315. The driven wheel 314 then drives the rotating rod 312 and the protective cover 313 to rotate, so that the protective cover 313 closes the protective shell 31. At this time, the panoramic camera 38 and the infrared thermal imager 39 are inside the protective shell 31 and the protective cover 313, thereby avoiding damage to the panoramic camera 38 and the infrared thermal imager 39 in harsh environments, thereby improving and extending the service life of the equipment; S3. When the panoramic camera 38 and the infrared thermal imager 39 enter the inner wall of the protective shell 31, the cleaning component 4 starts to work, and the small air compressor 42 starts to compress the air and spray the gas through the cleaning jet pipe 43 and a group of air outlet nozzles to form a high-speed airflow to clean the lens and surface of the panoramic camera 38 and the infrared thermal imager 39, remove dust, debris and other pollutants on the surface of the equipment, prevent these pollutants from affecting the light transmittance and imaging clarity of the equipment, and ensure that the equipment can continuously and accurately collect images and thermal imaging information of power facilities, thereby providing reliable data support for power inspection work.
