[0046] The working principle of the 5G base station DC power distribution cabinet disclosed by the application is as follows: in the initial state, the active cleaning assembly and the passive cleaning assembly are located above or below the cabinet body 1, and the cleaning roller or the scraper 39 is in contact with the cabinet body 1; for the convenience of description, it is assumed that in the initial state, the active cleaning assembly and the passive cleaning assembly are located below the cabinet body 1, and the scraper 39 is in contact with the cabinet body 1; when it is necessary to clean the cabinet body 1, the second motor 23 is started, the second motor 23 drives the third gear 22 to rotate, and since the third gear 22 and the rack 38 form a gear-rack transmission, at this time, the first mounting seat 15 drives the connecting side plate 10 to slide, the connecting side plate 10 drives the two straight sliding blocks 11 on the two sides to slide upwards in the height direction of the cabinet body 1, and the scraper on the active cleaning assembly and the passive cleaning assembly scrapes stubborn stains located outside the cabinet body 1; when the active cleaning assembly and the passive cleaning assembly move to the upper part of the cabinet body 1, the stop rod 26 is in contact with the conversion driving plate 14, at this time, there is a gap between the two ends of the driving ring 36 and the fixed ring 37, at this time, the rotary drum 27 rotates relative to the active rotating shaft 20, and in the rotating process, the driving block 28 provided thereon pushes the two sliding rods 29 outward, the sliding rod 29 drives the unlocking column 33 to slide outward in the straight sliding block 11, pushes the sliding column 34 out of the straight sliding block 11, and releases the locking between the straight sliding block 11 and the rotating plate 12, at this time, one end of the driving ring 36 is in contact with the fixed ring 37, and as the active cleaning assembly continues to rise, the stop rod 26 continues to drive the rotary drum 27 to rotate, on the one hand, the rotary drum 27 drives the active rotating shaft 20 to rotate through the driving ring 36 and the fixed ring 37, the driving block 28 drives the two rotating plates 12 to rotate, the active cleaning assembly and the passive cleaning assembly are converted from the state that the scraper is in contact with the cabinet body 1 to the state that the cleaning roller is in contact with the cabinet body 1, at this time, the first bevel gear 17 on the active cleaning assembly and the passive cleaning assembly forms bevel gear cooperation, and on the other hand, the sliding rod 29 is separated from the protruding part of the driving block 28, and under the action of the first spring 31, the unlocking column 33 slides away from the sliding column 34, and since the second bevel gear 18 exists, the active rotating shaft 20 in the active cleaning assembly and the passive rotating shaft 19 in the passive cleaning assembly rotate synchronously, and simultaneous switching is realized.

[0047] After the conversion to the state that the cleaning roller is in contact with the cabinet body 1, the second motor 23 reverses rotation, and the active cleaning assembly and the passive cleaning assembly move downwards, since the second gear 21 and the rack 38 form a gear transmission, the second gear 21 drives the fourth gear 25 to rotate through the gear shaft 24, the fourth gear 25 drives the first gear 9 to rotate, the first gear 9 drives the active cleaning roller 8 to rotate, the active cleaning roller 8 drives the passive cleaning roller 13 to rotate through the first bevel gear 17, and thus the cleaning of the cabinet body 1 by the cleaning roller is realized, and when moving to the lower part of the cabinet body 1, the above steps are repeated, and the conversion to the cleaning by the scraper 39 is realized, and the operation is repeated in turn.
