The patent with the application number CN202310064768.4 discloses a safety protection device for a distribution network line transformer, including a transformer body, a wiring bushing, and a protection component. The wiring bushing is fixedly arranged on the transformer body, and the protection component is arranged on the wiring bushing. The wiring bushing includes a pipe column and multiple groups of porcelain disks. The pipe column is fixedly arranged on the transformer body, and multiple groups of porcelain disks are fixedly arranged on the pipe column at equal intervals. The protection component includes a housing unit, a lagging and chasing double-drive unit, a resistance adjustment unit, and a split connection unit. The housing unit is arranged on the transformer body, the lagging and chasing double-drive unit and the resistance adjustment unit are both arranged inside the housing unit, and the split connection unit passes through the housing unit and is arranged on one side of the wiring bushing.

[0003] When the existing distribution network line transformer is in use, the distribution network transformer erected outdoors is often affected by the weather. Since the insulating sleeve of the transformer is exposed to the air for a long time, a large amount of dust and other impurities are easily accumulated on its surface. At the same time, some water stains will adhere to it on rainy days, reducing the surface insulation strength of the sleeve and making flashover accidents likely to occur. Moreover, when the insulating sleeve is damaged, it is not easy to be detected in time, thus affecting the safe operation of the transformer.

The side wall of the U-shaped frame 902 is rotatably connected to an extrusion roller 904 through a first rotating shaft 903. The second reset component 10 includes a support plate 1001 fixedly connected to the inner side wall of the box body 1702.

[0049] Under the action of the third spring 1003, the extrusion roller 904 squeezes the washed absorbent cotton belt 19 against the side wall of the baffle 901, so as to squeeze and dehydrate the washed absorbent cotton belt 19, ensure the cleanliness and water absorption effect of the absorbent cotton belt 19, and further ensure the safety protection effect.

The output end of the second motor 2303 is fixedly connected with a third gear 2304 meshing with the gear ring 2301. When the second motor 2303 is started, the rotation of the second motor 2303 drives the rotation of the third gear 2304, thereby driving the gear ring 2301 and the rotating ring 15 to rotate.

[0051] The reset mechanism 24 includes a third connecting block 2401 fixedly connected to the bottom of the arc-shaped plate 116. Two symmetrically arranged third T-shaped guide rods 2402 are inserted into the side wall of the third connecting block 2401. One end of the third T-shaped guide rod 2402 is fixed to the side wall of the moving box 17. A sixth spring 2403 is sleeved on the side wall of each third T-shaped guide rod 2402. Under the action of the sixth spring 2403, the absorbent cotton belt 19 can always be in contact with the surface of the insulating sleeve 101, so as to comprehensively clean the dust, water stains, etc. on the surface of the insulating sleeve 101, and the cleaning efficiency is higher and the effect is better.

[0052] The working principle of the present invention:

[0053] In the present invention, during use, when it is necessary to clean impurities such as dust and water stains on the surface of the insulating sleeve 101, the first motor 805 is started. The rotation of the first motor 805 drives the rotation of the second gear 806, thereby driving the rotation of the first gear 803 and the second rotating shaft 801. The rotation of the second rotating shaft 801 drives the rotation of the conveying roller 802, and further drives the conveying of the absorbent cotton belt 19. Through the absorbent cotton belt 19, the dust and other impurities on the surface of the insulating sleeve 101 can be cleaned, and the water stains can be absorbed. At the same time, the second motor 2303 is started. The rotation of the second motor 2303 drives the rotation of the third gear 2304, thereby driving the rotation of the toothed ring 2301 and the rotating ring 15. When the rotating ring 15 rotates, it drives the moving box 17 to rotate through the arc-shaped plate 16 and the reset mechanism 24. Moreover, the lifting module 12 drives the second U-shaped plate 13 to move downward, and further drives the rotating ring 15 and the moving box 17 to move downward. And, under the action of the sixth spring 2403, the absorbent cotton belt 19 can always be in contact with the surface of the insulating sleeve 101, so that the dust and water stains on the surface of the insulating sleeve 101 can be comprehensively cleaned, with higher cleaning efficiency and better effect. Thus, it can provide a safety protection effect for the insulating sleeve 101, and further provide a safety protection effect for the transformer body 1, which is safer and more reliable.

[0054] During cleaning, under the guiding action of the rotating rod 202, the absorbent cotton belt 19 can be conveyed into the cleaning tank 201. At this time, it can be cleaned. At the same time, when the second rotating shaft 801 rotates, it drives the rotating disk 2108 and the tapered rod 2109 to rotate. When the tapered rod 2109 abuts against the top of the moving plate 2104, it can push the second connecting plate 2105 and the triangular block 2106 downward. At the same time, the second spring 2103 is compressed. When the tapered rod 2109 passes over the top of the moving plate 2104, the second connecting plate 2105 and the triangular block 2106 can move upward and reset under the action of the second spring 2103. Repeating this process, the second connecting plate 2105 and the triangular block 2106 can move reciprocally. When the triangular block 2106 abuts against the end of the first moving rod 2107, it can push the first moving block 203 to move. At the same time, the first spring 304 is compressed. When the triangular block 2106 passes over the first moving rod 2107, the first moving block 203 can move and reset under the action of the first spring 304. Repeating this process, the first moving block 203 can drive the first brush bristles 204 to move reciprocally, so as to reciprocally clean the surface of the absorbent cotton belt 19, making the cleaning more efficient and effective.

[0055] Meanwhile, under the action of the third spring 1003, the squeezing roller 904 squeezes the washed water-absorbing cotton belt 19 against the side wall of the baffle 901, so as to squeeze and dehydrate the washed water-absorbing cotton belt 19, ensure the cleanliness and water absorption effect of the water-absorbing cotton belt 19, and further ensure the safety protection effect.

[0056] The infrared spectrum sensor 207 is used to detect the water in the cleaning tank 201 to determine whether there is oil stain. If there is oil stain, it indicates that the insulating sleeve 101 is damaged, which is convenient for detecting the damage condition of the insulating sleeve 101, and is safer and more reliable. When the moving plate 2104 moves up and down reciprocally, the connecting frame 2204 drives the second moving block 401 and the second brush 402 to move synchronously and reciprocally. Therefore, before the water-absorbing cotton belt 19 cleans the insulating sleeve 101, the second brush 402 can reciprocally clean the surface of the insulating sleeve 101, which can not only improve the cleaning efficiency and effect of the subsequent water-absorbing cotton belt 19, but also avoid damage to the water-absorbing cotton belt 19 caused by larger impurities.

[0057] Moreover, under the action of the fourth spring 602, the ball 503 can abut against the surface of the washed water-absorbing cotton belt 19 and roll on its surface. When the surface of the water-absorbing cotton belt 19 is damaged, under the action of the fourth spring 602, the tapered block 502 is inserted into the water-absorbing cotton belt 19. At this time, the second moving rod 601 and the retaining disc 603 move towards the water-absorbing cotton belt 19, so as to push the push plate 708 to move towards the fixed plate 501, and then drive the rotating plate 705 to rotate counterclockwise along the third rotating shaft 704. The proximity switch 702 detects the induction block 707, and an alarm is given through an external alarm to remind the operator to replace the water-absorbing cotton belt 19 in time, so as to facilitate the detection of the damage condition of the water-absorbing cotton belt 19, ensure its cleaning and water absorption effect on the insulating sleeve 101, and further ensure the safety protection effect on the transformer body 1;

[0058] After the cleaning is completed, the lifting module 12 can drive the second U-shaped plate 13 and the rotating ring 15 to move upward and reset. At this time, the surface of the insulating sleeve 101 can be cleaned again, making the cleaning more efficient and effective.
