Description

Technical Field

[0001] The present application relates to the technical field of high-voltage transmission line operation and maintenance equipment, and in particular to an insulator string thermal deicing and cleaning device. Background Art

[0002] An insulator string refers to a component of a flexible suspended conductor that is composed of two or more insulator elements. An insulator string is a protective device with fixing and operation requirements. It is used to suspend the conductor and insulate the conductor from the tower and the ground. The insulator string used in the transmission line has different assembly types due to differences in tower structure, insulator structure type, conductor size, number of conductors per phase, and voltage level. However, it can be generally divided into two categories: suspension insulator string and tension insulator string.

[0003] In the prior art, there is an automatic deicing device for an insulator string provided by publication number CN112735700A, which includes: an ice-breaking mechanism for applying an impact force to the insulator; and a running mechanism for adjusting the position of the ice-breaking mechanism so that the ice-breaking mechanism applies an impact force to each insulator in the insulator string. The deicing device provided by the prior art can automatically de-ice the ice layer on the insulator string by using the cooperation between the ice-breaking mechanism and the running mechanism, thereby avoiding manual de-icing and effectively reducing the risks caused by de-icing work.

[0004] The above-mentioned prior art is to de-ice the insulators by applying an impact force to the insulators through an ice-breaking mechanism. When de-icing is performed in this way, when encountering a situation where the ice is thick, a larger knocking force is required, and multiple knocks are required to complete the de-icing work. In this case, it is easy to cause damage to the insulator itself, affecting the normal use of the insulator. Secondly, when de-icing is performed by knocking, the ice layer is subjected to the knocking force, and the force point will break into ice chips, and the ice chips are scattered at qualified positions of the insulator string. Due to the low ambient temperature, the scattered ice chips will quickly and firmly adhere to the insulator string again, and need to be cleaned again, thereby increasing the de-icing efficiency of the insulator string. Summary of the invention

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1 to 8 This application is described in further detail.

[0033] The embodiment of the present application discloses a thermal deicing and cleaning device for an insulator string, which can de-ice insulator strings in different setting states, so that the insulator strings will not lose their functions due to ice in cold weather.

[0034] Reference Figure 1 An insulator string thermal deicing and cleaning device comprises a connecting slide bar 1, wherein the number of the connecting slide bars 1 is two and they are symmetrically arranged front to back, the two connecting slide bars 1 are commonly provided with two groups of vertically symmetrical clamping mechanisms 2 for locking on the insulator string, the number of each group of clamping mechanisms 2 is two and they are symmetrical front to back, the two connecting slide bars 1 are commonly provided with two front-to-back symmetrical thermal deicing mechanisms 5 for thermally melting the ice on the insulator string, the thermal deicing mechanisms 5 are provided with two auxiliary deicing mechanisms 4 for auxiliary deicing which are symmetrical left to right and which assist in melting ice, and an auxiliary protection mechanism 3 for receiving and discharging water generated in the process of melting ice is provided on the thermal deicing mechanisms 5 and below the auxiliary deicing mechanisms 4.

[0035] Reference Figure 1 and Figure 3 The thermal deicing mechanism 5 includes an adjusting slide 51 which is slidably connected to the connecting slide rod 1 up and down. The adjusting slide 51 is fixed on the connecting slide rod 1 by a first limiting bolt. A sealing frame 52 is fixedly connected to a side of the adjusting slide 51 close to the insulator string. A plurality of electric heating plates 53 are evenly distributed on the inner wall of the sealing frame 52. The two sealing frames 52 are spliced ​​together, and a card strip (not shown in the figure) and a connecting card slot adapted to the card strip are respectively provided on the splicing surfaces of the two sealing frames 52.

[0036] Reference Figure 2Taking the clamping mechanism 2 on the front side as an example, the clamping mechanism 2 includes a connecting slide 21 that is slidably connected to the connecting slide rod 1 up and down, and the connecting slide 21 is kept fixed on the connecting slide rod 1 by a second limiting bolt. The rear surface of the connecting slide 21 is fixedly connected to a connecting frame 22, and the rear surface of the connecting frame 22 is fixedly connected to a clamping plate 23. The clamping plate 23 is provided with two connecting holes that penetrate front and back and are symmetrical left and right. The rear surface of the clamping plate 23 is evenly and elastically slidably connected with a plurality of adaptable clamping columns 24 between the two connecting holes.

[0037] During specific use, first, the adjusting slides 51 are respectively mounted on the two connecting slides 1, and then the adjusting slides 51 are kept fixed on the connecting slides 1 by the first limiting bolt, and then the connecting slide 21 is mounted on the connecting slide 1 and is located above the adjusting slide 51, and the connecting slide 21 is kept fixed on the connecting slide 1 by the second connecting bolt. At this time, the clamping plates 23 connected by the connecting frame 22 on the two connecting slides 1 are spliced, and the two clamping plates 23 are placed on the front and rear sides of the top of the insulator string, and then the two clamping plates 23 are clamped on the insulator string by connecting bolts through the two connecting holes on the clamping plates 23. At the same time, through the setting of multiple adapter clamping columns 24, the two clamping plates 23 are gradually approached to each other by tightening the connecting bolts.

[0038] When the adapter clamping column 24 contacts the insulator, the adapter clamping column 24 slides toward the inside of the clamping plate 23 due to resistance. According to the different positions of contact with the insulator, the adapter clamping columns 24 at different positions shrink to different distances toward the inside of the clamping plate 23, thereby clamping the two clamping plates 23 on the insulator. Repeat the above steps to install the clamping plate 23 at the bottom of the insulator string until the upper and lower groups of clamping plates 23 are fully installed.

[0039] A rubber contact head (not shown in the figure) is provided at one end of the adapter clamping column 24 close to the insulator string. The adapter clamping column 24 cooperates with the rubber contact head to clamp on the insulator string to protect the surface of the insulator string.

[0040] It should be noted that before the two clamping plates 23 are fully clamped on the insulator string, the position of the adjusting slide 51 on the connecting slide rod 1 is adjusted so that the sealing frames 52 on the two adjusting slides 51 are aligned in the horizontal direction. During the clamping process of the two clamping plates 23, the two sealing frames 52 are simultaneously driven to move towards each other. When the opposite surfaces of the two sealing frames 52 are attached together, the two sealing frames 52 are connected together by the clamping strips and connecting slots on the opposite surfaces. When the position of the sealing frames 52 is adjusted, the two sealing frames 52 move synchronously.

[0041] Reference Figure 4Taking the auxiliary protection mechanism 3 on the right side of the rear side blocking frame 52 as an example, the auxiliary protection mechanism 3 includes a supporting plate 35 fixedly connected to the lower surface of the blocking frame 52, and a plurality of guide members 34 for drainage distributed front and back are arranged between the upper surface of the supporting plate 35 and the lower surface of the blocking frame 52. A plurality of front-to-back distributed mounting transverse plates 32 are fixedly connected to the right side surface of the blocking frame 52, and a connecting member 33 for connecting the guide member 34 is arranged on the mounting transverse plate 32. A pulling member 31 for cooperating with the connecting member 33 to adjust the position of the guide member 34 is commonly arranged at the right ends of the plurality of mounting transverse plates 32.

[0042] During specific use, before using the blocking frame 52, first pull the pulling member 31 to adjust the position of the guide member 34 through the connecting member 33, and pull the guide member 34 in the opposite direction away from the insulator to avoid the guide member 34 hindering the adjustment position of the blocking frame 52 when adjusting the position of the blocking frame 52. After pulling it to the specified position, limit the pulling member 31 on the mounting cross plate 32, so that the guide member 34 remains limited after the adjustment position.

[0043] Reference Figure 5 and Figure 6 The pulling member 31 includes a connecting slide bar 312 elastically and slidably connected to the front end mounting cross plate 32 and a limiting slide bar 314 elastically and slidably connected to the rear end mounting cross plate 32. The right ends of the connecting slide bar 312 and the limiting slide bar 314 are fixedly connected to a pulling plate 311. The left side of the pulling plate 311 is fixedly connected to a plurality of pull ropes 313 distributed front and back. The plurality of pull ropes 313 correspond one to one to the plurality of mounting cross plates 32. The limiting slide bar 314 is kept fixed on the mounting cross plate 32 by a third limiting bolt.

[0044] Reference Figure 5 , Figure 6 and Figure 7 The connecting member 33 includes a mounting block 333 slidably connected to the mounting horizontal plate 32, and a through groove adapted to the mounting block 333 is provided on the mounting horizontal plate 32. The top of the mounting block 333 is fixedly connected to a limiting plate 331, and the limiting plate 331 is slidably connected to the upper surface of the mounting horizontal plate 32. The bottom end of the mounting block 333 is fixedly connected to a sliding column 332, and the upper surface of the sliding column 332 is slidably connected to the lower surface of the mounting horizontal plate 32. A connecting spring is arranged between the sliding column 332 and the blocking frame 52, and the left end of the pull rope 313 is connected to the mounting block 333.

[0045] During specific use, when pulling the pulling member 31, the staff applies a pulling force to the pulling plate 311, and the pulling plate 311 drives multiple pulling ropes 313 to be synchronously pulled out from the inside of the mounting cross plate 32. When the pulling plate 311 is pulled to the specified position, the limiting slide 314 is limited on its corresponding mounting cross plate 32 by the third limiting bolt on the limiting slide 314, so that the position of the pulling plate 311 remains fixed. At the same time, the pulling rope 313 pulls the mounting block 333 to move synchronously. The limiting plate 331 is used to limit the mounting block 333 to keep sliding horizontally on the inner side of the mounting cross plate 32. At the same time, the mounting block 333 drives the sliding column 332 to move, and the connecting spring between the sliding column 332 and the blocking frame 52 is stretched.

[0046] Reference Figure 7 The guide member 34 includes a guide plate 342 slidably connected between the upper surface of the supporting plate 35 and the lower surface of the blocking frame 52. The upper surface of the guide plate 342 is fixedly connected to the sliding column 332. An assembly groove 341 is provided on the front surface of the guide plate 342. An assembly bar 344 is fixedly connected to the rear surface of the guide plate 342. Guide grooves 343 arranged on the left and right are provided on the upper surface of the guide plate 342. The positions of the assembly grooves 341 and the assembly bars 344 on two adjacent guide plates 342 correspond to each other. The assembly grooves 341 and the assembly bars 344 on two adjacent guide plates 342 are slidably connected. The depth of the guide groove 343 gradually deepens in the direction away from the insulator string.

[0047] During specific use, when the mounting block 333 drives the sliding column 332 to slide on the mounting cross plate 32, the sliding column 332 drives the guide plate 342 to slide synchronously, and the multiple guide plates 342 are synchronously pulled out toward the outside of the blocking frame 52. The multiple guide plates 342 are arranged in a close fit between the supporting plate 35 and the blocking frame 52, and two adjacent guide plates 342 are clamped together by the assembly strip 344 and the assembly groove 341, so that the multiple guide plates 342 are tightly spliced ​​together and can slide relative to each other.

[0048] After the clamping plates 23 are fixed at both ends of the insulator string, the two connecting slides 1 for installing the sealing frames 52 are respectively inserted into the two upper and lower connecting slides 21, and then the second limiting bolt is used to keep the connecting slide 21 and the connecting slide 1 relatively fixed. Then, after the limit of the adjusting slide 51 on the connecting slide 1 is cancelled by the first limiting bolt, the position of the adjusting slide 51 is adjusted by moving the adjusting slide 51 up and down on the connecting slide 1, so that the sealing frame 52 is aligned with the insulator, and then the first limiting bolt is used again to limit the position of the sealing frame 52 so that the position of the sealing frame 52 remains fixed.

[0049] Reference Figure 8The auxiliary de-icing mechanism 4 includes two track slides 43 fixedly connected to the outer surface of the blocking frame 52 at the angle position, which are symmetrical with the vertical line at the angle line as a reference. The two track slides 43 are slidably connected to the limiting slide 42, and the limiting slide 42 is kept fixed on the track slide 43 by a fourth limiting bolt. Two elastic telescopic connecting rods 41 symmetrical in upper and lower directions are fixedly connected to the side of the limiting slide 42 close to the blocking frame 52. The ends of the two elastic telescopic connecting rods 41 away from the limiting slide 42 are commonly fixedly connected with a connecting plate 44, and an electric heating head 45 is fixedly installed on the end of the connecting plate 44 away from the elastic telescopic connecting rod 41, and the end of the connecting plate 44 away from the elastic telescopic connecting rod 41 passes through the interior of the blocking frame 52 and is slidably connected to the blocking frame 52.

[0050] During actual use, after the position of the sealing frame 52 is adjusted, the position of the limit slide 42 on the track slide 43 is adjusted so that the electric heating head 45 is in contact with the ice layer of the insulator. At the same time, the limit slide 42 is continued to be pushed to compress the elastic telescopic connecting rod 41, and then the limit slide 42 is kept fixed on the track slide 43 by the fourth limit bolt.

[0051] The limit of the limit slide bar 314 on the third limit bolt is then cancelled. Since the connecting slide bar 312 and the limit slide bar 314 are elastically slidably connected to the mounting cross plate 32, the pull plate 311 is restored to its original position under the action of the elastic force. At this time, the pull plate 311 no longer generates tension on the pull rope 313, and the sliding post 332 is restored to its original position under the action of the elastic force of the connecting spring on the sliding post 332. At this time, the sliding post 332 drives the guide plate 342 to slide toward the inside of the blocking frame 52. When there is no insulator between the two guide plates 342 set on the left and right, the two guide plates 342 set on the left and right are in contact with each other. When there is an insulator between the two guide plates 342 set on the left and right, the two guide plates 342 set on the left and right are respectively in contact with the insulators. At this time, multiple guide plates 342 block the bottom of the blocking frame 52.

[0052] At this time, the electric heating plate 53 and the electric heating head 45 are energized to start the de-icing work, and multiple electric heating heads 45 are heated. Since the elastic telescopic connecting rod 41 is in a compressed state, under the action of elastic force, when the electric heating head 45 heats and melts the ice layer, the elastic telescopic connecting rod 41 continues to push the electric heating head 45 to move toward the insulator, so that the electric heating head 45 can continue to melt the ice layer, and multiple electric heating heads 45 can divide the ice layer on the insulator into blocks, and cooperate with the electric heating plate 53 to heat the internal space enclosed by the two sealing frames 52, so that the ice layer can be quickly separated from the insulator.

[0053] At the same time, water produced by melting the ice layer during the heating process drips onto the guide plate 342 at the bottom of the sealing frame 52. Since the depth of the guide groove 343 gradually deepens in the direction away from the insulator string, the water can flow smoothly from the inside of the guide groove 343 to the deeper direction, and is discharged to the outside of the sealing frame 52 through the guide groove 343 opened on the guide plate 342, thereby preventing the water from dripping directly on the insulator string, thereby completing the de-icing work of an insulator on the insulator string, and repeating the above steps to sequentially de-ice multiple insulators on the insulator string.

[0054] Therefore, based on the above-mentioned embodiments, the present application can perform de-icing work on insulator strings of different specifications. Specifically, the bottom of the sealing frame 52 of insulator strings of different sizes is sealed by the auxiliary protection mechanism 3, and the connecting slide bars 1 of different lengths are used to cooperate with the clamping mechanism 2 to de-ice insulator strings of different lengths and in unset states. At the same time, the present application can adjust the position of the electric heating head 45 by adjusting the distance that the connecting plate 44 extends into the sealing frame 52, so as to melt and divide the ice layers of different thicknesses on different insulators or at different positions on the same insulator, thereby further improving the scope of application of the present application.

[0055] The implementation principle of this application is:

[0056] (1) First, clamp the clamping mechanisms 2 in groups of two at the two ends of the insulator string that needs to be de-iced, and then insert the connecting slide rods 1 of appropriate length into the two clamping mechanisms 2 distributed up and down, and at the same time, use the first limit bolt to keep the clamping mechanisms 2 and the connecting slide rods 1 relatively fixed.

[0057] (2) At the same time, before the connecting slide bar 1 is inserted into the clamping mechanism 2, the adjusting slide seat 51 is sleeved on the connecting slide bar 1. When the connecting slide bar 1 and the clamping mechanism 2 are firmly fixed, the position of the adjusting slide seat 51 on the connecting slide bar 1 is adjusted according to the position of the insulator on the insulator string, so that the position of the blocking frame 52 corresponds to the position of the insulator.

[0058] (3) Then, the connecting member 33 is pulled by the pulling member 31 to slide on the mounting horizontal plate 32 , and the guiding member 34 is pulled outward on the blocking frame 52 , and the position of the guiding member 34 is limited by the pulling member 31 .

[0059] (4) When the adjusting slide 51 is sleeved on the connecting slide rod 1, the blocking frames 52 on the two adjusting slides 51 are locked together. When the positions of the blocking frames 52 are adjusted, the two blocking frames 52 move synchronously.

[0060] (5) After the position of the blocking frame 52 is adjusted, the electric heating plate 53 is used to heat and start thermal deicing of the ice layer on the insulator. At the same time, the auxiliary deicing mechanism 4 is used to separate the ice layer on the insulator string into blocks so that the ice layer can be quickly removed from the insulator string.

[0061] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
