Description

Technical Field

[0001] The invention belongs to the technical field of insulators, and in particular relates to an anti-fouling self-cleaning post electric porcelain insulator. Background Art

[0002] Post insulators are a special type of insulating control component that can play an important role in overhead transmission lines. In the early years, post insulators were mostly used on utility poles, and gradually developed into high-type high-voltage power line connection towers with many suspended insulators hung on one end. It is to increase the creepage distance. It is usually made of silicone or ceramics and is called an insulator.

[0003] The prior art has the following problems: the post porcelain insulator plays two basic roles in the overhead transmission line, namely supporting the conductor and preventing the current from returning to the ground. These two roles must be guaranteed, but in actual use, there is dirt on the post porcelain insulator. The presence of dirt will cause the insulator to form dirty flash during use, thereby causing flashover breakdown, etc. Therefore, it is necessary to clean the post porcelain insulator, but the existing cleaning device has a complex structure or high cost of use. At the same time, patent number CN113035466B discloses an anti-fouling self-cleaning snap-on post porcelain insulator. This technical solution has great disadvantages in actual use. On the one hand, the cleaning brush in its technical solution is always attached to the surface of the insulator. If it is not cleaned, the risk of flashover breakdown will be directly increased because the cleaning brush does not have the advantage of self-cleaning. At the same time, the cleaning method using cleaning liquid, etc. in the technical solution will also greatly increase the flashover breakdown caused by conduction. Therefore, this problem is urgently needed. Summary of the invention

[0027] In a preferred embodiment, please refer to Figure 6-Figure 8The pneumatic cleaning arm assembly 200 includes an air intake shaft tube arm 201 and a cleaning arm 202. A first conflicting arm 204 and a toothed gear 203 are fixedly arranged at the bottom of the air intake shaft tube arm 201, and a fixed arm disc 205 is fixedly arranged at the top of the air intake shaft tube arm 201. A shaft frame tube 206 is rotatably arranged at the bottom end surface of the fixed arm disc 205 through a bearing. A gear arm disc 209 is fixedly arranged on the outer wall of the shaft frame tube 206. A second conflicting arm 211 is fixedly arranged at the bottom end surface of the gear arm disc 209. A plurality of first linkage arms 207 are rotatably arranged on the fixed arm disc 205, and a plurality of second linkage arms 211 are rotatably arranged on the gear arm disc 209. The movable arm 208, the second linkage arm 208 and the first linkage arm 207 are connected at the far end by an axle pin, a bottom of the cleaning arm 202 is provided with a chassis end platform 215 and a ventilation hose 214, and a plurality of cleaning auxiliary arms 213 are fixedly provided on the outer side of the top of the cleaning arm 202, and a cleaning brush 216 and an air outlet slot 212 are provided on the cleaning auxiliary arm 213, an arc spring 210 is fixedly provided between the second abutting arm 211 and the first abutting arm 204, a gear arm disc 209 is provided below the fixed arm disc 205, and the gear arm disc 209 is rotatably provided on the periphery of the intake shaft tube arm 201, and the arc spring 210 abuts against the second abutting arm 211 and the first abutting arm 204. Between the conflict arm 211 and the first conflict arm 204, the bottom frame end platform 215 of the plurality of cleaning arms 202 is fixed on the distal arm body of the first linkage arm 207, the cleaning arm 202 is connected to the air intake shaft tube arm 201 through the ventilation hose 214, the air intake shaft tube arm 201 is arranged on the pillow block 111, the geared gear 203 is located inside the annular bin 112, the first conflict arm 204 is located outside the annular bin 112, the geared gear 203 is located between the toggle inner gear ring 105 and the limit outer gear ring 102, and one side of the geared gear 203 is meshed with the outer side of the toggle inner gear ring 105, and the other side of the geared gear 203 is meshed with the outer side of the toggle inner gear ring 105. Engaged with the inner side of the limiting outer gear ring 102, through the pushing of the arc spring 210, in the natural state, the gear arm disk 209 rotates clockwise at the bottom of the fixed arm disk 205, and through the cooperation of the first linkage arm 207 and the second linkage arm 208 on the fixed arm disk 205 and the gear arm disk 209, multiple cleaning arms 202 form a ring-shaped self-expanding cleaning arm structure on the periphery of the intake shaft tube arm 201. When the pneumatic cleaning arm assembly 200 moves on the insulator assembly 100, when the gear arm disk 209 passes through the arc-shaped limiting tooth 106, a fixed-point meshing structure is formed between the gear arm disk 209 and the arc-shaped limiting tooth 106.

[0028] In summary, when in use, the air inlet of the inclined air inlet pipe 107 is connected to the external pressurized air supply device through a pipeline. At this time, the air outlet of the inclined air inlet pipe 107 is inclined toward the fins 103 and forms a pressurized wind pushing structure for the fins 103. When high-pressure air is introduced into the inclined air inlet pipe 107, the high-pressure air pushes the inner gear ring 105 to rotate in the annular chamber 112 through the fins 103. Since one side of the geared gear 203 is meshed with the outer side of the geared gear 203, and the other side of the geared gear 203 is meshed with the outer side of the geared gear 203, the geared gear 203 is meshed with the outer side of the geared gear 203. It meshes with the inner side of the limiting outer gear ring 102, and the limiting outer gear ring 102 is fixed in the annular bin 112. When the inner gear ring 105 is driven by the wind, through the cooperation of the above structure, the gear 203 forms a ring-shaped and self-rotating structure in the annular bin 112, that is, at this time, the pneumatic cleaning arm assembly 200 forms a ring-shaped and self-rotating cleaning drive structure on the insulator assembly 100, that is, the wind force is converted into the driving force for the pneumatic cleaning arm assembly 200 to move and rotate for cleaning.

[0029] On the basis of the above, that is, on the basis of the circular movement and self-rotation of the pneumatic cleaning arm assembly 200, when the pneumatic cleaning arm assembly 200 is circumferentially moved on the insulator assembly 100, the cleaning brush 216 on the cleaning arm 202 performs circular cleaning on the support porcelain insulator 101, and when the pneumatic cleaning arm assembly 200 is self-rotating on the insulator assembly 101, the cleaning brush 216 on the cleaning arm 202 performs self-rotating cleaning on the support porcelain insulator 101. Through such circular movement and self-rotating cleaning, the cleaning effect of the support porcelain insulator 101 can be fully guaranteed. At the same time, the wind entering from the inclined air intake pipe 107 will enter the air intake shaft tube arm 201, and the wind in the air intake shaft tube arm 201 will enter the cleaning shaft through the ventilation hose 214. The wind is discharged from the multiple cleaning sub-arms 213 on the arm 202 and from the air outlet slots 212 on the cleaning sub-arms 213. On the basis of the circular movement and self-rotation of the pneumatic cleaning arm assembly 200, the wind discharged from the air outlet slots 212 on the cleaning sub-arms 213 forms a circular movement and self-rotation blowing cleaning structure for the support porcelain insulator 101. In this way, the support porcelain insulator 101 is cleaned again, that is, on the basis of the circular movement and self-rotation of the pneumatic cleaning arm assembly 200, the cleaning brush 216 cleans the support porcelain insulator 101 once by the circular movement and self-rotation, and on the basis of the circular movement and self-rotation of the pneumatic cleaning arm assembly 200, the air outlet slots 212 cleans the support porcelain insulator 101 twice by the circular movement and self-rotation.

[0030] On the basis of the above, when the support porcelain insulator 101 is circling and rotating for cleaning, the cleaning brush 216 on the cleaning auxiliary arm 213 abuts against the outside of the support porcelain insulator 101. The specific structure is as follows: through the push of the arc spring 210, in a natural state, the gear arm disc 209 rotates clockwise at the bottom of the fixed arm disc 205, and through the cooperation of the first linkage arm 207 and the second linkage arm 208 on the fixed arm disc 205 and the gear arm disc 209, multiple cleaning arms 202 form a ring-shaped self-expanding cleaning arm structure on the periphery of the intake shaft tube arm 201. Through this self-expanding structure, the cleaning brushes 216 on the multiple cleaning auxiliary arms 213 abut against the outside of the support porcelain insulator 101, and during the circling process, When the gear arm disc 209 rotates to the arc-shaped limit tooth 106, the gear arm disc 209 is meshed with the arc-shaped limit tooth 106, and the gear arm disc 209 rotates counterclockwise under the fixed arm disc 205. At this time, through the cooperation of the first linkage arm 207 and the second linkage arm 208 on the fixed arm disc 205 and the gear arm disc 209, multiple cleaning arms 202 form a ring-shaped self-folding cleaning arm structure on the periphery of the intake shaft tube arm 201. At this time, multiple cleaning arms 202 are folded around the periphery of the intake shaft tube arm 201. Through this fixed-point folding, the cleaning brush 216 on the cleaning arm 202 is away from the support porcelain insulator 101 when not cleaning, thereby avoiding affecting the normal use of the support porcelain insulator 101.

[0031] It should be emphasized that the wind discharged from the air outlet slot 212 of the present invention also forms a blowing cleaning effect on the cleaning brush 216, that is, the cleaning brush 216 forms a cleaning structure for the support porcelain insulator 101, and the wind discharged from the air outlet slot 212 forms a secondary cleaning structure for the cleaning brush 216.

[0032] It should be emphasized that the pneumatic cleaning arm assembly 200 of the present invention cleans the support porcelain insulator 101 in a circumferential and self-rotating manner, and the cleaning brush 216 has a certain cleaning range when it circumferentially and self-rotates, that is, when the pneumatic cleaning arm assembly 200 rotates to the fixed position of the arc-shaped limit tooth 106, the radiation of this cleaning range can ensure that the surface of the support porcelain insulator 101 at the arc-shaped limit tooth 106 can also be cleaned, and there is no blind spot for cleaning.

[0033] In another embodiment of the present invention, a magnet may be provided at the arc-shaped limit tooth 106, and a magnet may be provided on the pneumatic cleaning arm assembly 200. The two magnets have opposite magnetic properties. When the pneumatic cleaning arm assembly 200 rotates to the position of the arc-shaped limit tooth 106, the inclined air inlet pipe 107 may be cut off from the wind. At this time, the magnets attract each other, so that the pneumatic cleaning arm assembly 200 stays at the position of the arc-shaped limit tooth 106 (during cleaning, the thrust of the wind is greater than the magnetic force). At the same time, when staying at the position of the arc-shaped limit tooth 106, the multiple cleaning arms 202 on the pneumatic cleaning arm assembly 200 form a ring-shaped self-folding cleaning arm structure, which fully ensures that when not cleaning, the cleaning brush 216 is in a state of being away from the support porcelain insulator 101.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
