[0045] It is worth noting that, in the embodiment, in order to improve the driving stability of the protective shell 26 , each lifting assembly may include two or more lifting screws 32 .

[0046] Specifically, in the present embodiment, the protective shell 26 comprises a main shell 35 and a cover body 36. A lifting plate 37 is provided at the lower end of the main shell 35. The lifting plate 37 is connected to the lifting screw 32 by a thread. The main shell 35 is set as an upper end open structure.

Two groups of cover bodies 36 are symmetrically provided on the opposite side walls of the main shell 35. When the cover needs to be opened, the two groups of cover bodies 36 are driven to rotate in opposite directions and open until they are in contact with the side walls of the main shell 35.

[0047] During specific use, before the robot leaves the warehouse, first start the flip motor 40 to drive the flip shaft 39 to rotate, and the flip shaft 39 drives the cover body 36 to open from the upper end of the main shell 35; then start the lifting motor 27 to rotate forward, and under the action of the second synchronous belt 33, the lifting motor 27 drives the transmission shaft 2 30 to rotate, and under the action of the third synchronous belt 34, the transmission shaft 2 30 drives the lifting drive shaft 31 to rotate, and the lifting drive shaft 31 drives the lifting screw 32 to rotate. Under the driving action of the lifting screw 32, the lifting plate 37 and the main shell 35 are driven to descend, and the main shell 35 descends along the outer side of the mobile carrier 1. When the main shell 35 descends to the lowest position, the detection device 5 is completely exposed.

[0048] The robot moves along the pre-set track to inspect the substation when it leaves the warehouse. During the inspection, the two sets of transmission shafts 12 are driven to rotate in opposite directions by the meshing of the two sets of transmission gears 14 under the action of the rotating motor 11, and the corresponding rotating shaft 8 is driven to rotate by the first synchronous belt 13, and the rotating shaft 8 drives the scraper 7 and the rubber plate 15 to swing, and the scraper 7 cleans the track surface during the swinging process.

[0049] As the use time increases, the rubber sheet 15 will be worn. At this time, you only need to pull the force plate 22 outward, and the force plate 22 drives the fixing pin 20 to slide along the sliding groove 23. The free end of the fixing pin 20 moves out of the fixing hole 19, and the fixing installation of the fixing plate 18 and the rubber sheet 15 can be released. At this time, the fixing spring 24 is in a compressed state; after the fixing plate 18 of the new rubber sheet 15 is inserted into the fixing groove 16, the force plate 22 is released, and the fixing spring 24 is extended. Under the action of the fixing spring 24, the free end of the fixing pin 20 can be driven to be embedded in the fixing hole 19 of the fixing plate 18, thereby realizing the installation of the rubber sheet 15.
