Two driving mechanisms are arranged and respectively installed on the first guide half ring 17 and the second guide half ring 18, each driving mechanism comprises a second motor 21 and a gear 22, the second motor 21 is fixedly installed on the first guide half ring 17 and the second guide half ring 18, the gear 22 is fixedly installed on an output shaft of the second motor 21, the gear 22 on the first guide half ring 17 is meshed with the rack 16 of the first guide half ring 17, and the gear 22 on the second guide half ring 18 is meshed with the rack 16 of the second guide half ring 18. In operation, the second motor 21 drives the gear 22 to rotate, so as to drive the rack 16 to rotate, the rotation of the rack 16 is a reciprocating motion, and is realized by the forward and reverse rotation of the second motor 21, at this time, the sliding portions 12 in the sliding rails 11 of the first guide half ring 17 and the second guide half ring 18 also perform corresponding circular motion, and at this time, the cleaning air bags 13 on the sliding portions 12 also perform circular motion, so as to clean the outer surface of the insulator. Of course, considering the engagement between the rack 16 and the gear 22, the circular motion of the rack 16, the sliding part 12, the cleaning air bag 13, etc. can be performed only at a certain angle, and therefore, the cleaning air bag 13 should be as close to a semicircular ring as possible to wrap the outer surface of the insulator as much as possible and achieve efficient cleaning.

The top surfaces of the first guide half ring 17 and the second guide half ring 18 are respectively provided with arc-shaped through holes 19, the rack 16 penetrates out of the through holes 19 upwards, and the limiting of the sliding parts 12 on the first guide half ring 17 and the second guide half ring 18 can be realized by arranging the through holes 19 and the way that the rack 16 penetrates through the through holes 19 and extends out, so that the sliding parts 12 are prevented from jumping off, and the sliding parts 12 can only do circular motion. Considering that the sliding part 12 may enter the sliding rail 11 of the second guiding half ring 18 from the sliding rail 11 of the first guiding half ring 17 or enter the sliding rail 11 of the first guiding half ring 17 from the sliding rail 11 of the second guiding half ring 18 during the circular motion of the sliding part 12, further, both end parts of the sliding part 12 on the first guiding half ring 17 and the second guiding half ring 18 are respectively chamfered, and at this time, both end parts of the sliding part 12 are smaller than the middle part, which is advantageous for the sliding part 12 to enter the sliding rail 11 of the second guiding half ring 18 from the sliding rail 11 of the first guiding half ring 17 or enter the sliding rail 11 of the first guiding half ring 17 from the sliding rail 11 of the second guiding half ring 18, thereby ensuring the smooth circular motion of the sliding part 12 and the cleaning airbag 13 thereon. In order to achieve smooth sliding of the sliding portion 12 in the slide rail 11 of the first guide half ring 17 and the second guide half ring 18, balls are provided on the inner side walls of the slide rail 11 of the first guide half ring 17 and the second guide half ring 18, and the sliding portion 12 is in contact with the balls, so that sliding friction during sliding of the sliding portion 12 is changed into rolling friction, and friction is reduced to achieve smooth sliding.

Considering that a part of dust flies when cleaning, and at this time, if a large amount of dust falls onto the rack 16, the gear 22, or the second motor 21, etc., the operation of these components is greatly affected, for example, the rack 16 is not blocked and moved smoothly, the first guide half ring 17 and the second guide half ring 18 are further provided with a shielding cover 23 for shielding the rack 16, the gear 22, and the second motor 21, and the shielding cover 23 shields the rack 16, the gear 22, the second motor 21, etc., from above and from the side, so that dust falling onto the rack 16, the gear 22, and the second motor 21 can be reduced to a certain extent, and smooth operation of the rack 16, the gear 22, the second motor 21, etc., is ensured.
