[0037] Specifically, when in use, the cable is passed through the outer box 1 from the two through holes 2, and the cable is passed through the detection tube 4. At this time, the local discharge sensor 5 and the image acquisition module 6 on the inner wall of the detection tube 4 will face the outer wall of the cable, wherein the local discharge sensor 5 is used to detect whether a discharge phenomenon occurs at a local position of the cable, and the image acquisition module 6 is used to collect the appearance picture of the cable and upload it to the cloud server through the wireless module, so that maintenance personnel can remotely view the real-time picture and perform maintenance on the fault position in advance. Since the installation position of the cable on the high-voltage line is relatively high, the outer box 1 will often be blown by natural wind, and when the natural wind blows through the outer box 1, the driving part will drive the detection tube 4 to rotate, and the detection tube 4 can drive the local discharge sensor 5 and the image acquisition module 6 to revolve around the outer wall of the cable, so that the local discharge sensor 5 and the image acquisition module 6 can monitor the cable more comprehensively, and the moving part will drive the outer box 1 to move back and forth on the outer wall of the cable, so as to achieve the purpose of cyclic monitoring of the cable.

[0038] In practice, since cables are usually installed in parallel in threes, when using the present application, two outer boxes 1 at adjacent positions can be fixed by a connecting plate 38, so that three groups of outer boxes 1 can be moved and monitored synchronously, and the stability during movement can be improved.

[0043] Embodiment three:

[0044] Reference Figure 3 and Figure 4 , which is basically the same as the second embodiment, and further discloses a specific implementation scheme of the moving part.

[0048] Reference Figure 1-Figure 4 as well as Figure 6-Figure 8 , which is basically the same as Example 3, and further, a specific implementation plan for cleaning the outer wall of the cable is specifically added.

[0049] A cleaning tube 20 is rotatably installed in the above-mentioned two through holes 2, and the axis of the cleaning tube 20 is colinear with the axis of the detection tube 4. Circumferentially distributed fan blades 21 and brushes 22 are fixedly provided in the two cleaning tubes 20, and the two groups of brushes 22 are respectively close to the ports of the two through holes 2. The cleaning tube 20 is connected to the driving shaft 7 through a linkage component, and the outer wall of the outer box 1 is fixedly connected to an air intake pipe 34 connected thereto; the linkage part includes a transmission rod 27 rotatably connected to the outer box 1, one end of the transmission rod 27 is connected to the driving shaft 7 through two meshing second gears 29, and a driving gear 28 is fixedly installed on the other end of the transmission rod 27, and a ring gear 23 meshingly connected to the driving gear 28 is fixedly installed on the outer wall of the cleaning tube 20.

[0050] Specifically, during the rotation of the driving shaft 7, the driving shaft 7 will drive the transmission rod 27 to rotate through two meshing second gears 29, the transmission rod 27 will drive the ring gear 23 to rotate through the driving gear 28, the ring gear 23 will drive the cleaning tube 20 to rotate, the cleaning tube 20 will drive the fan blades 21 and the brush 22 on the inner wall to sweep in a circle, the brush 22 can clean the dust on the cable to prevent the dust from blocking the damaged part and affecting the monitoring, and the fan blades 21 can generate an airflow in the cleaning tube 20 that blows in the direction of the brush 22, so that the dust on the brush 22 and the dust on the cable can be blown off, ensuring the continuity of the cable cleaning, when the cleaning tube 20 blows air in the direction of the brush 22, the outer box 1 will absorb outside air through the air intake pipe 34.

[0051] The above-mentioned driving source includes a transverse hole 26 arranged on the outer wall of the outer box 1, a transverse shaft 15 is sleeved in the transverse hole 26, two symmetrically arranged active conical disks 16 are fixedly installed on the transverse shaft 15, a worm 36 is rotatably installed in the outer box 1 through the vertical shaft 14, and a worm wheel 13 meshingly connected with the worm 36 is fixedly installed on one of the rotating rods 11; wherein, a driven conical disk 18 abutting against the edge of one of the active conical disks 16 is fixedly installed on the vertical shaft 14, and the contact surfaces of the active conical disk 16 and the driven conical disk 18 are both provided with anti-slip grooves, and the two active conical disks 16 are arranged on both sides of the driven conical disk 18, a long rod-shaped gear 19 meshingly connected with the ring gear 23 is fixedly installed on the transverse shaft 15, and a U-turn component for driving the transverse shaft 15 to move axially back and forth is provided on the transverse shaft 15.

[0052] Specifically, during the continuous rotation of the ring gear 23, the ring gear 23 will drive the long rod-shaped gear 19 to rotate, the long rod-shaped gear 19 will drive the horizontal shaft 15 to rotate, the horizontal shaft 15 will drive the two active conical disks 16 to rotate, and the active conical disk 16 that abuts against the driven conical disk 18 will drive the driven conical disk 18 to rotate under the action of friction resistance, and the driven conical disk 18 will drive the worm 36 to rotate through the vertical shaft 14, and the worm 36 will drive the rotating rod 11 to rotate through the worm gear 13, and the rotating rod 11 will drive the roller 12 to roll on the cable, and the roller 12 will drive the outer box 1 to move along the outer wall of the cable, so that the partial discharge sensor 5 and the image acquisition module 6 can comprehensively monitor the cable.

[0053] The above-mentioned U-turn component includes a limit block 24 rotatably connected to the two ends of the horizontal axis 15, and a guide rod 30 is fixedly connected to the limit block 24, and the guide rod 30 is slidably inserted into the outer wall of the outer box 1; wherein, both ends of the horizontal axis 15 are rotatably connected to an annular plate 17 made of stainless steel, and the inner walls on both sides of the outer box 1 are fixedly connected to magnets 25, and the annular plate 17 on one side is adsorbed on the magnet 25.

[0054] Specifically, when the outer box 1 moves to the end of the cable, that is, close to the electric pole or electric tower for hanging the cable, the limit block 24 on one side of the outer box 1 will be reversely pressed by the electric pole, so that the horizontal axis 15 is subjected to axial pressure. When the annular plate 17 that absorbs the annular magnet 25 is pushed open, the horizontal axis 15 will slide along the axial direction due to inertia, and the weight of the cable will cause the middle part of the cable to bend downward, while the two ends will be tilted upward. Therefore, when the horizontal axis 15 is at both ends, it will also slide downward due to the downward gravity, and drive the two sets of annular plates 17 to move synchronously, and make the annular plate 17 on the other side absorb to the annular magnet 25 on the other side. At the same time, The horizontal axis 15 will also drive the active conical disk 16 to translate synchronously, and make the active conical disk 16, which was originally far away from the driven conical disk 18, fit on the driven conical disk 18, and drive the driven conical disk 18 to rotate. Since the two active conical disks 16 are respectively located on both sides of the driven conical disk 18, the driven conical disk 18 will start to reverse, thereby driving the roller 12 to roll in the opposite direction on the cable, and then driving the entire outer box 1 to move in the opposite direction along the cable. When the outer box 1 moves to the other end of the cable, it will move forward again according to the same principle as mentioned above. In this cycle, the outer box 1 will move back and forth on the outer wall of the cable, thereby achieving the purpose of cyclic monitoring of the cable.

[0055] In practice, the active cone disk 16 and the driven cone disk 18 may also be replaced by bevel gears, but when turning around, the gears may easily get knocked. Since the overall load is small, the impact is small.

[0056] Embodiment five:

[0057] Reference Figure 1-Figure 3, which is basically the same as the fourth embodiment, and further, a specific implementation scheme for powering the partial discharge sensor 5 and the image acquisition module 6 is specifically added.

[0058] A photovoltaic panel 31 is installed on the top of the outer box 1 . A battery for storing electric energy is installed on the photovoltaic panel 31 . The output end of the photovoltaic panel 31 is electrically connected to the input end of the partial discharge sensor 5 and the image acquisition module 6 .

[0059] Specifically, when the outer box 1 is in use, the photovoltaic panel 31 on the top of the outer box 1 can power the partial discharge sensor 5, the image acquisition module 6 and the battery, and the photovoltaic panel 31 can insulate the outer box 1 to reduce the impact of strong sunlight on the partial discharge sensor 5 and the image acquisition module 6.

[0060] Two symmetrically arranged support plates 32 are fixedly connected to the top of the outer box 1, and the photovoltaic panel 31 is fixedly installed on the top of the support plate 32. An air inlet groove 33 is formed between the photovoltaic panel 31, the two support plates 32 and the top of the outer box 1; wherein, filter screens 35 for filtering dust are installed at both ends of the air inlet groove 33, and the input end of the air inlet pipe 34 is located in the air inlet groove 33, and the outer wall of the detection tube 4 is provided with circumferentially distributed air inlet holes 37, and the input end of the air inlet pipe 34 faces the air inlet holes 37 on the outer wall of the detection tube 4.

[0061] Specifically, when the air intake pipe 34 absorbs external air, the air intake pipe 34 will suck air into the air intake groove 33, and the air intake groove 33 will suck air through the ports on both sides and filter out dust through the filter 35. When the air passes through the air intake groove 33, the photovoltaic panel 31 can be dissipated to ensure the service life of the photovoltaic panel 31. When the airflow is discharged from the air intake pipe 34, the airflow will blow toward the air intake hole 37 on the outer wall of the detection tube 4, and then enter the detection tube 4 from the air intake hole 37, and then flow from the detection tube 4 into the cleaning tube 20. When the airflow passes through the detection tube 4, the local discharge sensor 5 and the image acquisition module 6 in the detection tube 4 can also be dissipated to improve the working stability of the local discharge sensor 5 and the image acquisition module 6.

[0062] When the distribution network fault monitoring device is in use, the cable is passed through the outer box 1 from the two through holes 2, and the cable is passed through the cleaning tube 20, the two pairs of rollers 12 and the detection tube 4. At this time, the local discharge sensor 5 and the image acquisition module 6 on the inner wall of the detection tube 4 will face the outer wall of the cable, wherein the local discharge sensor 5 is used to detect whether a discharge phenomenon occurs at a local position of the cable, and the image acquisition module 6 is used to collect the appearance image of the cable and upload it to the cloud server through the wireless module, so that the maintenance personnel can remotely view the real-time image and perform maintenance on the fault position in advance and in time;

[0063] Since the installation position of the cable on the high-voltage line is relatively high, the outer box 1 is often blown by natural wind. When the natural wind blows through the outer box 1, the wind cup 8 drives the driving shaft 7 to rotate, and the driving shaft 7 drives the detection tube 4 to rotate through two meshing first gears 9. The detection tube 4 can drive the partial discharge sensor 5 and the image acquisition module 6 to revolve around the outer wall of the cable, so that the partial discharge sensor 5 and the image acquisition module 6 can monitor the cable more comprehensively.

[0064] During the rotation of the driving shaft 7, the driving shaft 7 will drive the transmission rod 27 to rotate through the two meshing second gears 29, and the transmission rod 27 will drive the ring gear 23 to rotate through the driving gear 28, and the ring gear 23 will drive the cleaning tube 20 to rotate, and the cleaning tube 20 will drive the fan blades 21 and the brush 22 on the inner wall to sweep in a circle. The brush 22 can clean the dust on the cable to prevent the dust from blocking the damaged part and affecting the monitoring, and the fan blades 21 can generate an airflow in the cleaning tube 20 that blows toward the brush 22, so that the dust on the brush 22 and the dust on the cable can be blown off, ensuring the continuity of the cable cleaning. When the cleaning tube 20 blows air in the direction of the brush 22, the outer box 1 will absorb the outside air through the air inlet pipe 34;

[0065] During the continuous rotation of the ring gear 23, the ring gear 23 will drive the long rod-shaped gear 19 to rotate, the long rod-shaped gear 19 will drive the horizontal shaft 15 to rotate, the horizontal shaft 15 will drive the two active conical disks 16 to rotate, the active conical disk 16 abutting against the driven conical disk 18 will drive the driven conical disk 18 to rotate under the action of friction resistance, the driven conical disk 18 will drive the worm 36 to rotate through the vertical shaft 14, the worm 36 will drive the rotating rod 11 to rotate through the worm gear 13, the rotating rod 11 will drive the roller 12 to roll on the cable, the roller 12 will drive the outer box 1 to move along the outer wall of the cable, so that the partial discharge sensor 5 and the image acquisition module 6 can perform comprehensive monitoring of the cable;

[0066] When the outer box 1 moves to the end of the cable, that is, close to the electric pole or electric tower for hanging the cable, the limit block 24 on one side of the outer box 1 will be reversely pressed by the electric pole, so that the horizontal axis 15 is subjected to axial pressure. When the annular plate 17 that attracts the annular magnet 25 is pushed open, the horizontal axis 15 will slide along the axial direction due to inertia, thereby driving the two sets of annular plates 17 to move synchronously, and the annular plate 17 on the other side is attracted to the annular magnet 25 on the other side. At the same time, the horizontal axis 15 will also drive the active conical disk 16 to translate synchronously, and make the active conical disk 16 that was originally far away from the outer box 1 The active cone disk 16 of the active cone disk 18 is attached to the driven cone disk 18 and drives the driven cone disk 18 to rotate. Since the two active cone disks 16 are respectively located on both sides of the driven cone disk 18, the driven cone disk 18 will start to reverse, thereby driving the roller 12 to roll in the opposite direction on the cable, and then driving the entire outer box 1 to move in the opposite direction along the cable. When the outer box 1 moves to the other end of the cable, it will move forward again according to the same principle as mentioned above. In this cycle, the outer box 1 will move back and forth on the outer wall of the cable, thereby achieving the purpose of cyclic monitoring of the cable.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
