The adjusting plate extends through the connecting slot and the adjusting slot to the inner side of the fixed outer shell. A connecting rack is fixedly connected to the side wall of the adjusting plate. A connecting shaft is rotatably mounted on the inner wall of the fixed outer shell. A connecting gear that meshes with the connecting rack is fixedly connected to the connecting shaft. A second reciprocating screw is rotatably mounted on the connecting plate. The second reciprocating screw passes through the adjusting plate and mechanically engages with the adjusting plate. An adjusting gear is fixedly connected to the side wall of the second reciprocating screw.

During the cleaning process of the cleaning plate and cleaning scraper, the pressure between the plate and the cable sheath can be increased intermittently, which increases the friction between the cleaning plate, the cleaning scraper and the sheath. While cleaning the firmly adhered debris, the plate can also be pulled. If the sheath is severely aged, it will be torn. The detection probe can detect the leakage of electricity when the sheath is torn, so that the cable sheath can be replaced and repaired in time, avoiding untimely maintenance. 3. During the movement of the cleaning scraper, the scraper rotates back and forth continuously, thereby squeezing and stretching the rubber between the scrapers to both sides, further tearing the aged rubber, which facilitates the detection of the detection probe and further improves the detection capability of aged rubber.

[0015] Reference Figures 1-8 A cable power leakage detection device for power distribution network maintenance, comprising: The detector body 1 has a protective shell 2 fixedly installed on its side wall. A base plate 3 is rotatably installed between the inner walls of the protective shell 2. A fixing plate 6 is fixedly connected to the base plate 3. A first reciprocating screw 7 and a rotating rod 8 are rotatably installed between the fixing plates 6. A fixing cable 10 is fixedly installed on the detector body 1. The fixing cable 10 extends to the base plate 3 and a detection probe 11 is fixedly installed thereon. The detector body 1 is a commonly used power leakage detection device on the market. The detection probe 11 is installed on the cable. The location of the power leakage is determined by the swing of the pointer on the detector body 1. like Figure 4 and Figure 5 As shown, the cleaning structure 4 includes a fixing ring 41, on which a connecting cover is rotatably mounted. Opening the connecting cover allows the cable to be inserted into the fixing ring 41 for cleaning. The connecting cover and the fixing ring 41 are combined in a ring shape. A cleaning fluid tank 42 is fixedly fitted onto the outer side of the fixing ring 41. The cleaning fluid is a solution mixed with alcohol and detergent, which can more effectively remove debris from the cable sheath. The cleaning fluid tank 42 is also ring-shaped. Both the cleaning fluid tank 42 and the fixing toothed ring 46 have openings corresponding to the connecting cover. The opening has a cleaning liquid tank 42 with a fixed tube 43 fixedly connected to it. The fixed tube 43 passes through the fixed ring 41 and extends to the inside of the fixed ring 41. A fixed nozzle 44 is fixedly installed on the fixed tube 43. A screw slider 47 is mechanically fitted on the first reciprocating screw 7. A fixed block 48 is sleeved on the rotating rod 8. The fixed block 48 and the screw slider 47 are both circumferentially slidably connected to the fixed ring 41. A transmission structure is installed on the fixed ring 41. An installation plate 49 is fixedly connected to the side wall of the fixed ring 41. A cleaning plate 410 is slidably installed on the installation plate 49. When the first reciprocating lead screw 7 rotates, it causes the lead screw slider 47, which is mechanically coupled with it, to move, which in turn causes the fixed ring 41 to move. Under the action of the transmission structure, the fixed ring 41 rotates, causing the fixed tube 43 and the fixed nozzle 44 mounted on the fixed ring 41 to rotate and move back and forth together. The fixed nozzle 44 sprays the cleaning fluid onto the cable sheath for cleaning. At the same time, when the fixed ring 41 moves, it causes the mounting plate 49 and the cleaning plate 410 to move together. When the cleaning plate 410 moves, it scrapes off the outer sheath of the cable, cleaning the cable sheath clean and preventing debris from affecting the detection probe 11 and causing detection errors, so as to facilitate the detection. like Figure 5 and Figure 6 As shown, a tension structure 5 is mounted on the mounting plate 49. The tension structure 5 includes a fixed outer shell 51 fixedly connected to the mounting plate 49 via a connecting plate 58. An adjusting plate 55 is slidably mounted on the cleaning plate 410. A connecting slot 56 corresponding to the adjusting plate 55 is opened on the inner wall of the mounting plate 49. An adjusting slot 57 corresponding to the adjusting plate 55 is opened on the inner wall of the fixed outer shell 51. The adjusting plate 55 extends through the connecting slot 56 and the adjusting slot 57 to the inner side of the fixed outer shell 51. A connecting rack 54 is fixedly connected to the side wall of the adjusting plate 55. A connecting shaft 52 is rotatably mounted on the inner wall of the fixed outer shell 51. A connecting gear 53 meshing with the connecting rack 54 is fixedly connected to the connecting shaft 52. A second reciprocating screw is rotatably mounted on the connecting plate 58. Rod 59, the second reciprocating lead screw 59 passes through the adjusting plate 55 and is mechanically engaged with the adjusting plate 55. The reciprocating spiral grooves of the second reciprocating lead screw 59 located on both sides are in opposite directions. Therefore, when it rotates, the adjusting plate 55 moves in opposite directions to avoid motion interference, which could damage the connecting gear 53 and the connecting rack 54. The side wall of the second reciprocating lead screw 59 is fixedly connected to the adjusting gear 510. The side walls of the lead screw slider 47 and the fixed block 48 are both fixedly connected to the adjusting rack 511 that meshes with the adjusting gear 510. The adjusting rack 511 is an arc centered on the center of the fixed ring 41. The connecting gear 53 and the connecting rack 54 are engaged with the second reciprocating lead screw 59 to ensure that the moving distances of the two adjusting plates 55 are the same but in opposite directions. During the rotation of the mounting plate 49, the connecting plate 58 and the fixed housing 51, which are fixedly mounted on the mounting plate 49, rotate accordingly, causing the second reciprocating screw 59 to rotate as well. This causes the adjusting gear 510, which is fixedly sleeved on the second reciprocating screw 59, to rotate as well. Under the action of the adjusting rack 511, the adjusting gear 510 rotates on its own axis, driving the second reciprocating screw 59 to rotate as well. This causes the adjusting plate 55, which is mechanically coupled to the second reciprocating screw 59, to move back and forth. When the adjusting plate 55 moves towards the inner side of the fixed ring 41, it drives the adjusting plate 55 to move back and forth. The connecting rack 54, which is fixedly connected to the section plate 55, moves together, causing the connecting gear 53, which meshes with the connecting rack 54, to rotate. This coordinates the movement of the two connecting racks 54, ensuring that the moving distance of the connecting racks 54 is equal. This avoids errors in the movement of the adjusting plate 55, which could lead to inconsistencies between the cleaning plates 410 and the cleaning scraper 513 on both sides. This would increase the pressure of the cleaning plate 410 on the cable sheath. As the cleaning plate 410 moves, the cable sheath will be pulled. If the cable sheath is severely aged, it will be torn, indicating that the sheath needs to be replaced. like Figure 6 and Figure 7 As shown, a side plate 517 is fixedly installed on the side wall of the cleaning plate 410. A threaded rod 514 is rotatably connected between the side plates 517. A cleaning scraper 513 is fixedly sleeved on the threaded rod 514. The threaded rod 514 passes through the side plate 517 and is threadedly sleeved with a threaded sleeve rod 515. A return spring is fixedly connected between the inner wall of the threaded sleeve rod 515 and the threaded rod 514. A pressing plate 516 is fixedly connected to the corresponding threaded sleeve rod 515. A second reciprocating screw 59 passes through the connecting plate 58 and is fixedly sleeved with a fixed cam 512. The fixed cam 512 corresponds to the pressing plate 516. The cleaning scraper 513 moves together with the cleaning plate 410 to clean the cable sheath. At the same time, as the second reciprocating screw 59 rotates, the fixed cam 512, which is fixedly sleeved on the second reciprocating screw 59, also rotates. During the rotation, the fixed cam 512 will squeeze the extrusion plate 516, causing the extrusion plate 516 to move and drive the threaded sleeve 515 to move towards the threaded rod 514. The return spring deforms, and under the action of the thread, the movement of the threaded sleeve 515 will cause the threaded rod 514 to rotate, which will drive the cleaning scraper 513 to rotate together. As the fixed cam 512 continues to rotate, the elastic force of the return spring will cause the extrusion plate 516 to move back, causing the threaded rod 514 to rotate back as well. This will cause the cleaning scraper 513 to rotate back and forth, further cleaning the sheath. Moreover, during the back and forth rotation, the cleaning scraper 513 will be subjected to tensile and compressive forces on the sheath between the cleaning scrapers 513, further tearing the sheath and thus detecting the aging state of the sheath. like Figure 8As shown, a sliding block 518 is fixedly connected to the adjusting plate 55, and a sliding groove 519 corresponding to the sliding block 518 is opened on the cleaning plate 410. A connecting spring 520 is fixedly connected between the inner wall of the sliding block 518 and the sliding groove 519. The sliding block 518 and the sliding groove 519 allow the adjusting plate 55 and the cleaning plate 410 to slide. When the adjusting plate 55 moves and the cleaning plate 410 cannot move, the connecting spring 520 will contract, increasing the force on the cleaning plate 410, thereby increasing the pressure of the cleaning plate 410 on the cable sheath. The side wall of the extrusion plate 516 has rounded corners. The outer sides of the fixed cam 512 and the extrusion plate 516 are both fixedly wrapped with a protective layer. The protective layer protects the fixed cam 512 and the extrusion plate 516 to prevent them from being damaged. like Figure 3 As shown, the transmission structure includes a motor 9 fixedly mounted on a fixed plate 6, a rotating rod 8 passing through the corresponding fixed plate 6 and fixedly connected to the output end of the motor 9, a first reciprocating screw 7 and a rotating rod 8 being connected by a belt transmission assembly 12, a fixed gear 45 being slidably sleeved on the rotating rod 8, and the fixed gear 45 being rotatably connected to the fixed block 48, and a fixed toothed ring 46 being fixedly sleeved on the fixed ring 41 and meshing with the fixed gear 45; When the motor 9 is started, the output end of the motor 9 drives the rotating rod 8 to rotate. Under the action of the belt drive assembly 12, the first reciprocating screw 7 rotates accordingly, causing the screw slider 47, which is mechanically engaged with the first reciprocating screw 7, to move back and forth along the first reciprocating screw 7, driving the fixed ring 41 and the fixed block 48 to move together. When the fixed block 48 moves, the fixed gear 45, which is rotatably connected to it, moves accordingly. At the same time, the fixed gear 45 will rotate with the rotating rod 8, driving the fixed gear ring 46, which meshes with the fixed gear 45, to rotate, causing the fixed ring 41 to rotate together. The cleaning fluid tank 42 has a filling port with a fixed plug. By opening the fixed plug, cleaning fluid can be added to the cleaning fluid tank 42. A fixed cover plate is mounted on the detector body 1 via a hinge. A handle is fixedly mounted on the fixed cover plate. By closing the fixed cover plate and using the handle, the detector body 1 can be lifted, thus facilitating the carrying of the device.

[0016] In this invention, when the device is in use, the detector body 1 is carried to the detection position, the fixing cover plate, the base plate 3 and the connecting cover plate are opened, the fixing ring 42 is wrapped around the cable inside, the connecting cover plate is closed, and the detection probe 11 is installed on the cable. The data detected by the detection probe 11 will be displayed on the detector body 1. At the same time, the location of the power leakage can be determined by the swing of the pointer on the detector body 1. Then, the motor 9 is started. The output end of the motor 9 drives the rotating rod 8 to rotate. Under the action of the belt drive assembly 12, the first reciprocating screw 7 rotates accordingly, causing the screw slider 47, which is mechanically engaged with the first reciprocating screw 7, to move back and forth along the first reciprocating screw 7. This causes the fixed ring 41 and the fixed block 48 to move together. When the fixed block 48 moves, the fixed gear 45, which is rotatably connected to it, moves accordingly. At the same time, the fixed gear 45 rotates with the rotating rod 8, causing the fixed gear ring 46, which meshes with the fixed gear 45, to rotate, making the fixed ring 41 rotate together. Rotate and move back and forth, so that the fixed tube 43 and the fixed nozzle 44 installed on the fixed ring 41 rotate and move back and forth together. The fixed nozzle 44 sprays the cleaning fluid onto the cable sheath for cleaning. At the same time, when the fixed ring 41 moves, it will drive the mounting plate 49 and the cleaning plate 410 to move together, so that the cleaning scraper 513 also moves. When the cleaning scraper 513 moves, it will scrape off the outer sheath of the cable, clean the cable sheath, and prevent debris from affecting the detection probe 11 and causing detection errors, so as to facilitate the detection. During the rotation of the mounting plate 49, the connecting plate 58 and the fixed housing 51 fixedly mounted on the mounting plate 49 rotate accordingly, driving the second reciprocating screw 59 to rotate as well. This causes the adjusting gear 510, which is fixedly sleeved on the second reciprocating screw 59, to rotate as well. Under the action of the adjusting rack 511, the adjusting gear 510 rotates on its own during rotation, driving the second reciprocating screw 59 to rotate as well. This causes the adjusting plate 55, which is mechanically engaged with the second reciprocating screw 59, to move back and forth. When the adjusting plate 55 moves towards the inside of the fixed ring 41, it increases the pressure of the cleaning scraper 513 on the cable sheath, improving the cleaning effect of the cleaning scraper 513. It can remove firmly adhered debris. Moreover, as the cleaning scraper 513 moves, the cable sheath is pulled, allowing for monitoring of the sheath's condition. Then, the adjusting plate 55 moves outward to prevent the cleaning scraper 513 from applying excessive force to the sheath for an extended period of time. In addition, as the second reciprocating screw 59 rotates, the fixed cam 512, which is fixedly sleeved on the second reciprocating screw 59, also rotates. During the rotation, the fixed cam 512 will squeeze the extrusion plate 516, causing the extrusion plate 516 to move and drive the threaded sleeve 515 to move towards the threaded rod 514. The return spring deforms, and under the action of the thread, the movement of the threaded sleeve 515 will cause the threaded rod 514 to rotate, driving the cleaning scraper 513 to rotate together. As the fixed cam 512 continues to rotate, the elastic force of the return spring causes the extrusion plate 516 to move back, causing the threaded rod 514 to rotate back as well, thereby causing the cleaning scraper 513 to rotate back and forth, further cleaning the rubber. Moreover, during the back and forth rotation of the cleaning scraper 513, the rubber between the cleaning scrapers 513 will be subjected to tensile and compressive forces, further tearing the rubber, thereby detecting the aging state of the rubber. If the cable rubber is severely aged, the rubber will be torn, indicating that the rubber needs to be replaced.
