Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of line maintenance, in particular to a split type single-phase grounding device suitable for overhead lines. BACKGROUND

[0002] In the related art, when the overhead line is under maintenance, a ground wire needs to be hung on the overhead line to prevent the maintenance personnel from being electrocuted by sudden power supply during the maintenance operation. However, the hanging of the ground wire is mostly performed manually at present, which is not only time-consuming and laborious, but also has a certain safety hazard. Moreover, the weight of the grounding device is relatively large, which is easy to cause damage to the overhead line due to long-term overloading. SUMMARY

[0003] The present application provides a split type single-phase grounding device suitable for overhead lines, which aims to solve the problem of manual hanging of the ground wire on the overhead line in the related art.

[0004] In order to solve the above-mentioned problems existing in the related art, the present application provides a split type single-phase grounding device suitable for overhead lines, which includes an insulating rope, a rope frame, a wire clamping device, an electric control device and two ground wires. The rope frame is used to be hung on the overhead conductor by a drone or an insulating pole, and the middle part of the insulating rope is hung on the rope frame. The electric control device has a clamping jaw mechanism and two winch roller assemblies located on opposite sides respectively. The electric control device is detachably connected to the wire clamping device through the clamping jaw mechanism. The wire clamping device is located above the electric control device. The wire clamping device has two conductive connecting pieces located on opposite sides respectively. One end of each of the two ground wires is arranged on each of the two connecting pieces. A vertical through hole is formed in each of the two connecting pieces. The two ends of the insulating rope pass through the two through holes respectively and are wound on the two winch roller assemblies respectively. Specifically, the electric control device is used to control the two winch roller assemblies to rotate in the same direction synchronously to wind the two ends of the insulating rope synchronously, so that the electric control device and the wire clamping device ascend together. When the wire clamping device ascends to the overhead conductor, the wire clamping device clamps the overhead conductor, and the overhead conductor is electrically connected to the two connecting pieces through the wire clamping device. The clamping jaw mechanism is controlled to open to separate the wire clamping device from the electric control device. The two winch roller assemblies are controlled to rotate in the opposite direction synchronously to release the two ends of the insulating rope synchronously, so that the electric control device descends alone for recycling.

[0005] In some implementations, the wire clamping device includes a housing, a guide rod, a conductive strip, a movable clamp block, a driven magnet, a transmission mechanism, and a conductive fixed clamp block, the housing has a clamping opening at the top for accommodating the overhead wire and avoiding the rope holder, the fixed clamp block is arranged on the housing, the guide rod, the movable clamp block, and the transmission mechanism are arranged in the housing, the fixed clamp block and the movable clamp block are respectively located at opposite ends of the housing, the guide rod is arranged along the length direction of the housing, the movable clamp block is slidably sleeved on the guide rod, the driven magnet is rotatably arranged in the housing and below the fixed clamp block, the driven magnet is in transmission connection with the movable clamp block through the transmission mechanism, two connecting members are respectively arranged on the opposite two outer side walls of the housing in the width direction, one end of the conductive strip is arranged on the fixed clamp block, and the other end is bifurcated and arranged on the two connecting members respectively; the electric control device includes a housing, a driving magnet, and a power execution mechanism, the power execution mechanism is arranged in the housing, the driving magnet is rotatably arranged in the housing, the power execution mechanism is in transmission connection with the driving magnet, two winding wheel assemblies are respectively arranged on the opposite two outer side walls of the housing in the width direction, the driving magnet and the driven magnet are coaxially arranged, one end of the driving magnet penetrates out of the top of the housing, one end of the driven magnet penetrates out of the bottom of the housing, the driven magnet and the driving magnet are spaced apart and magnetically coupled. The electric control device is used for: when the wire clamping device rises to the overhead wire, controlling the power execution mechanism to drive the driving magnet to drive the driven magnet to rotate synchronously, so that the transmission mechanism converts the rotation of the driven magnet into the sliding of the movable clamp block along the guide rod to the fixed clamp block, so as to clamp the overhead wire between the movable clamp block and the fixed clamp block, and electrically connect the overhead wire to the two connecting members through the conductive strip. In addition, the electric control device further includes a controller arranged in the housing and in communication connection with the power execution mechanism.

[0006] In some implementations, the power execution mechanism includes a first bevel gear, a second bevel gear, and a motor in communication connection with the controller, the first bevel gear is sleeved on the output shaft of the motor, and the second bevel gear is arranged on the end face of the one end of the driving magnet in the housing and is in meshing connection with the first bevel gear.

[0007] In some implementations, the transmission mechanism includes a lead screw, a third bevel gear, and a fourth bevel gear, the lead screw is arranged along the length direction of the housing, the third bevel gear is sleeved on one end of the lead screw, the fourth bevel gear is arranged on the end face of the one end of the driven magnet in the housing and is in meshing connection with the third bevel gear, and the movable clamp block is sleeved on the lead screw and is in threaded connection with the lead screw through the self-provided threaded hole.

[0008] In some implementations, the wire clamping device further includes a limiting block and a first pressure sensor communicatively connected to the controller. The limiting block is located inside the housing, positioned at the clamping opening and corresponding to the overhead conductor. The first pressure sensor is embedded in the surface of the limiting block facing the overhead conductor. Specifically, the first pressure sensor is used to detect in real time whether the limiting block is in contact with the overhead conductor during the process of the electronic control device raising the wire clamping device together. When the limiting block is in contact with the overhead conductor, the controller controls the power actuator to drive the active magnet to rotate, thereby clamping the overhead conductor between the fixed clamping block and the movable clamping block.

[0009] In some implementations, the clamping device further includes a second pressure sensor communicatively connected to the controller. The second pressure sensor is embedded in the side of the movable clamping block facing the fixed clamping block. Specifically, the second pressure sensor is used to detect the clamping force on the overhead conductor in real time as the movable clamping block slides along the guide rod toward the fixed clamping block and clamps the overhead conductor together with the fixed clamping block, and transmits this information to the controller. The controller is also used to control the power actuator to stop driving the active magnet to rotate when the clamping force is within a preset clamping force range, that is, to stop the sliding of the movable clamping block along the guide rod toward the fixed clamping block.

[0010] In some implementations, the electronic control device also includes a dual-axis motor housed within the housing and communicatively connected to the controller, with both output shafts extending out of the housing and respectively connected to two winch assemblies.

[0011] In some implementations, the bottom of the housing has two clamping ears, one near each of the opposite ends of the housing. The top of the housing has two openings corresponding to the clamping ears. Two gripper mechanisms, both communicatively connected to a controller, are located inside the housing and correspond to the two openings, extending from each opening. The controller controls the synchronous opening and closing of the two gripper mechanisms. When synchronously closed, the two gripper mechanisms clamp the two clamping ears to connect the wire clamping device and the electrical control device; or when synchronously opened, they release the two clamping ears to separate the wire clamping device from the electrical control device.

[0012] In some implementations, the gripper mechanism includes a servo motor, a cam, a transmission rod, two rotating shafts, two clamps, two transverse connecting rods, and two oblique connecting rods. The servo motor is communicatively connected to a controller. The cam is mounted on the output shaft of the servo motor. One end of the transmission rod is rotatably connected to the base circle end of the cam. One end of each of the two transverse connecting rods is rotatably connected to the other end of the transmission rod. One end of each of the two rotating shafts is spaced apart on the inner wall of the housing along the sliding direction of the movable clamp. Both rotating shafts are perpendicular to the inner wall of the housing and are located above the two transverse connecting rods. One end of each of the two oblique connecting rods is rotatably connected to the other end of each of the two transverse connecting rods. The other end of each of the two oblique connecting rods is rotatably fitted onto the ends of the two rotating shafts away from the inner wall of the housing. One end of each of the two clamps is rotatably connected to the end of each of the two oblique connecting rods fitted onto the corresponding rotating shaft. The other end of each clamp extends out of the housing from the corresponding opening. The ends of each clamp that connect with the corresponding oblique connecting rod are provided with arc-shaped gears, and the arc-shaped gears of the two clamps mesh with each other.

[0013] In some implementation schemes, in addition to the structure given above, the electronic control device also includes two elastic couplings. The two elastic couplings are respectively disposed on two opposite outer walls of the housing in the width direction and are located above the two winch assemblies. The elastic coupling includes a sleeve, a slide rod, a coupling joint, and a return spring. The sleeve is disposed on the outer wall of the housing and arranged in the vertical direction. The slide rod is slidably inserted into the sleeve. The coupling joint is disposed at the end of the slide rod away from the corresponding winch assembly. The return spring is sleeved on the slide rod. One end of the return spring abuts against the coupling joint, and the other end is fixed to the inner wall of the sleeve. The coupling joint is used to abut against the connector on the same side. The slide rod has an axially extending rope hole. The two ends of the insulating rope pass through the two through holes and the two rope holes respectively and are wound around the two winch assemblies respectively.

[0014] In some implementations, the top of the movable clamp has a hook that bends and extends toward the fixed clamp. This hook is used to abut against the corresponding position of the fixed clamp when the overhead conductor is clamped between the movable clamp and the fixed clamp, thereby confining the overhead conductor within a closed annular space formed by the movable clamp, the fixed clamp, and the outer shell.

[0015] The split-type single-phase grounding device provided in this application consists of an insulating rope, a rope frame, a clamping device, an electrical control device, and two grounding wires. The rope frame is used to hang on the overhead conductor via a drone or an insulating pole, and the middle part of the insulating rope is hung on the rope frame. The electrical control device has a gripper mechanism and two winch assemblies located on opposite sides. The electrical control device is detachably connected to the clamping device via the gripper mechanism. The clamping device is located above the electrical control device and has two conductive connectors located on opposite sides of the clamping device. One end of each of the two grounding wires is located on the two connectors, and each connector has a vertically extending through hole. The two ends of the insulating rope pass through the two through holes and are wound around the two winch assemblies. In practical applications, the middle of the insulating rope is attached to a rope frame, which is then attached to the overhead conductor using a drone or insulating pole. Both ends of the insulating rope are then passed through the through holes on the two connectors of the clamping device. The ends of the rope are then wound around the two winch assemblies in the electrical control device. The electrical control device then controls the two winch assemblies to rotate synchronously to wind up both ends of the insulating rope, causing the electrical control device to rise along with the clamping device. When the clamping device reaches the overhead conductor, the electrical control device clamps the conductor, allowing it to... The overhead conductor is electrically connected to two connectors (i.e., electrically connected to two grounding wires respectively located on the two connectors) via a clamping device, thus achieving grounding of the overhead conductor. Subsequently, the electrical control device first controls the gripper mechanism to open, separating the clamping device from the electrical control device. Then, it controls the two winch assemblies to synchronously reverse, releasing both ends of the insulating rope, allowing the electrical control device to descend to the ground independently, leaving only the clamping device with the grounding wire on the overhead conductor. Afterwards, the two ends of the insulating rope are pulled out from the two winch assemblies and the two connectors, and the electrical control device is retrieved. Therefore, compared to the traditional method of manually attaching the grounding wire to the overhead conductor, this application achieves automated grounding wire attachment, saving time and labor, and reducing the safety hazards associated with personnel climbing to heights. Furthermore, the clamping device and electrical control device of this application are designed as separate units; during use, only the clamping device with the grounding wire remains on the overhead conductor, effectively reducing the weight of the grounding device, lowering the load on the overhead conductor, and preventing damage to the overhead conductor due to excessive load over a long period.

Detailed Implementation

[0030] In related technologies, when overhead lines are shut down for maintenance, a ground wire needs to be installed on the overhead lines. The ground wire is the lifeline for maintenance personnel, preventing electric shock caused by sudden power restoration during maintenance work. However, currently, the installation of ground wires is mostly done manually, which is time-consuming, labor-intensive, and poses significant safety hazards. In view of this, this application proposes a split-type single-phase grounding device suitable for overhead lines in the embodiments below, in order to solve the above-mentioned drawbacks of related technologies.

[0031] To make the objectives, technical solutions, and advantages of this application more apparent and understandable, this application will be clearly and completely described below in conjunction with its embodiments and corresponding drawings. Throughout, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. It should be understood that the embodiments of this application described below are only for explaining this application and are not intended to limit this application. That is, all other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0032] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of a split-type single-phase grounding device. Figure 2 yes Figure 1 A magnified view of a portion of point A in the middle. Figure 3 This is the first exploded schematic diagram of a split-type single-phase grounding device. Figure 4 yes Figure 3A partial enlarged view at point B. This embodiment provides a split-type single-phase grounding device suitable for overhead lines, which includes a rope frame 1, an insulating rope 2, a clamping device 3, an electrical control device 4, and two grounding wires 5. The rope frame 1 is used to hang on the overhead conductor via a drone or an insulating pole. The middle part of the insulating rope 2 is hung on the rope frame 1. The electrical control device 4 has a gripper mechanism 42 and two winch assemblies 45 located on opposite sides. The electrical control device 4 is detachably connected to the clamping device 3 via the gripper mechanism 42. The clamping device 3 is located above the electrical control device 4. The clamping device 3 has two conductive connectors 34 located on opposite sides of the clamping device 3. One end of each of the two grounding wires 5 is provided on the two connectors 34. Each of the two connectors 34 has a vertically extending through hole. The two ends of the insulating rope 2 pass through the two through holes and are wound around the two winch assemblies 45.

[0033] In this embodiment, the electronic control device 4 is used to: control the two winch assemblies 45 to rotate synchronously in the forward direction to synchronously wind up both ends of the insulating rope 2, so that the electronic control device 4 carries the wire clamping device 3 upward together; when the wire clamping device 3 rises to the overhead conductor, control the wire clamping device 3 to clamp the overhead conductor, and make the overhead conductor electrically connected to the two connectors 34 through the wire clamping device 3; control the gripper mechanism 42 to open so that the wire clamping device 3 is separated from the electronic control device 4; control the two winch assemblies 45 to rotate synchronously in the reverse direction to synchronously release both ends of the insulating rope 2, so that the electronic control device 4 descends alone for recovery.

[0034] In other words, in practical applications, the process of attaching the grounding wire 5 is as follows: the middle part of the insulating rope 2 is attached to the rope frame 1, and the rope frame 1 is attached to the overhead conductor by a drone or insulating pole. Then, both ends of the insulating rope 2 are passed through the through holes on the two connectors 34 in the clamping device 3, and the two ends of the insulating rope 2 are wound around the two winch assemblies 45 in the electric control device 4. Subsequently, the electric control device 4 controls the two winch assemblies 45 to rotate synchronously to synchronously wind up the two ends of the insulating rope 2, so that the electric control device 4 carries the clamping device 3 upward together. When the clamping device 3 rises to the overhead conductor, the electric control device 4 controls the clamping device 3 to clamp. Holding the overhead conductor, the conductor is electrically connected to the two connecting parts 34 via the clamping device 3 (i.e., electrically connected to the two grounding wires 5 respectively located on the two connecting parts 34). This grounding of the overhead conductor is achieved. Then, the electrical control device 4 first controls the gripper mechanism 42 to open, separating the clamping device 3 from the electrical control device 4. Next, it controls the two winch assemblies 45 to simultaneously reverse, releasing both ends of the insulating rope 2, allowing the electrical control device 4 to descend to the ground independently. Only the clamping device 3 with the grounding wire 5 remains on the overhead conductor. Afterward, the two ends of the insulating rope 2 are pulled out from the two winch assemblies 45 and the two connecting parts 34, and the electrical control device 4 is retrieved. It is understood that after power maintenance, the rope frame 1 and clamping device 3 on the overhead conductor need to be removed. This process is the reverse of the process of attaching the grounding wire 5, and therefore will not be described further.

[0035] As can be seen from the above, compared with the traditional solution of manually hanging the grounding wire 5, this embodiment realizes the automated hanging of the grounding wire 5, which saves time and effort and can also reduce the safety hazards caused by personnel climbing to heights. Moreover, the clamping device 3 and the electrical control device 4 of this embodiment adopt a split design. When in use, only the clamping device 3 with the grounding wire 5 is left on the overhead conductor, which can effectively reduce the weight of the grounding device, reduce the load on the overhead conductor, and avoid damage to the overhead conductor due to excessive load over a long period of time.

[0036] In some embodiments, please combine Figures 5 to 8 , Figure 5 This is the second exploded schematic diagram of a split-type single-phase grounding device. Figure 6 yes Figure 5 A magnified view of a section at point C. Figure 7 This is a front view of a split-type single-phase grounding device. Figure 8 yes Figure 7 A magnified view of a section at point D. The wire clamping device 3 includes a housing 31, a guide rod 32, a conductive strip 33, a movable clamping block 35, a driven magnet 37, a transmission mechanism 38, and a conductive fixed clamping block 36. The top of the housing 31 has a clamping opening for accommodating overhead wires and avoiding the rope frame 1. The fixed clamping block 36 is disposed on the housing 31. The guide rod 32, the movable clamping block 35, and the transmission mechanism 38 are all disposed inside the housing 31. The fixed clamping block 36 and the movable clamping block 35 are respectively located at opposite ends of the housing 31. The guide rod 32 is arranged along the length direction of the housing 31. The movable clamping block 35 is slidably sleeved on the guide rod 32. The driven magnet 37 is rotatably disposed inside the housing 31 and located below the fixed clamping block 36. The driven magnet 37 is connected to the movable clamping block 35 through the transmission mechanism 38. Two connecting parts 34 are respectively disposed on the two opposite outer side walls of the housing 31 in the width direction. One end of the conductive strip 33 is disposed on the fixed clamping block 36, and the other end is forked and disposed on the two connecting parts 34 respectively.

[0037] The electronic control device 4 includes a housing 41, an active magnet 43, and a power actuator 44. The power actuator 44 is located inside the housing 41, and the active magnet 43 is rotatably located inside the housing 41. The power actuator 44 is drive-connected to the active magnet 43. Two winch assemblies 45 are respectively located on two opposite outer side walls of the housing 41 in the width direction. The active magnet 43 and the driven magnet 37 are coaxially arranged. One end of the active magnet 43 protrudes from the top of the housing 41, and one end of the driven magnet 37 protrudes from the bottom of the housing 31. The driven magnet 37 and the active magnet 43 are spaced apart and magnetically coupled. In addition, the electronic control device 4 also includes a power supply and a controller located inside the housing 41. The power supply is used to provide power, and the controller is communicatively connected to the power actuator 44, the gripper mechanism 42, etc., inside the housing 41 to control them.

[0038] Based on this, the electronic control device 4 is used to: when the clamping device 3 rises to the overhead conductor, control the power actuator 44 to drive the active magnet 43 to drive the driven magnet 37 to rotate synchronously, so that the transmission mechanism 38 converts the rotation of the driven magnet 37 into the sliding of the movable clamping block 35 along the guide rod 32 to the fixed clamping block 36, so as to clamp the overhead conductor between the movable clamping block 35 and the fixed clamping block 36, so that the overhead conductor is electrically connected to the two connecting members 34 through the conductive strip 33.

[0039] As at least one embodiment, the top of the movable clamp 35 is formed with a hook portion 351 that bends and extends toward the fixed clamp 36. The hook portion 351 is used to abut against the corresponding position of the fixed clamp 36 when the overhead wire is clamped between the movable clamp 35 and the fixed clamp 36, thereby confining the overhead wire within the closed annular space formed by the movable clamp 35, the fixed clamp 36 and the outer shell 31.

[0040] As at least one embodiment, the power actuator 44 includes a first bevel gear 442, a second bevel gear 443, and a motor 441 connected to the controller. The first bevel gear 442 is sleeved on the output shaft of the motor 441, and the second bevel gear 443 is located on the end face of the driving magnet 43 located inside the housing 41 and meshes with the first bevel gear 442. The transmission mechanism 38 includes a lead screw 381, a third bevel gear 382, ​​and a fourth bevel gear 383. The lead screw 381 is arranged along the length of the housing 31, the third bevel gear 382 is sleeved on one end of the lead screw 381, and the fourth bevel gear 383 is located on the end face of the driven magnet 37 located inside the housing 31 and meshes with the third bevel gear 382. The movable clamping block 35 is sleeved on the lead screw 381 and threadedly engages with the lead screw 381 through its own threaded hole.

[0041] As at least one embodiment, the clamping device 3 further includes a limiting block and a first pressure sensor communicatively connected to the controller. The limiting block is located inside the housing 31, positioned at the clamping opening and corresponding to the overhead conductor. The first pressure sensor is embedded in the surface of the limiting block facing the overhead conductor. Specifically, the first pressure sensor is used to detect in real time whether the limiting block is in contact with the overhead conductor during the process of the electronic control device 4 carrying the clamping device 3 upwards. The controller is used to control the power actuator 44 to drive the active magnet 43 to rotate when the limiting block is in contact with the overhead conductor, so as to clamp the overhead conductor between the fixed clamping block 36 and the movable clamping block 35. Understandably, when the limit block comes into contact with the overhead conductor, it indicates that the clamping device 3 has risen to the correct position. The first pressure sensor is triggered by the pressure of the overhead conductor (sending a trigger signal to the controller). After receiving the trigger signal, the controller can control the power actuator 44 to drive the active magnet 43 to rotate, causing the movable clamping block 35 to slide towards the fixed clamping block 36. Finally, the overhead conductor will be clamped between the movable clamping block 35 and the fixed clamping block 36.

[0042] In at least one embodiment, the clamping device 3 further includes a second pressure sensor communicatively connected to the controller. The second pressure sensor is embedded in the side of the movable clamping block 35 facing the fixed clamping block 36. Specifically, the second pressure sensor is used to detect the clamping force on the overhead conductor in real time during the process of the movable clamping block 35 sliding along the guide rod 32 toward the fixed clamping block 36 and clamping the overhead conductor together with the fixed clamping block 36, and transmits the data to the controller. The controller is also used to control the power actuator 44 to stop driving the active magnet 43 to rotate when the clamping force is within a preset clamping force range, that is, to stop the sliding of the movable clamping block 35 along the guide rod 32 toward the fixed clamping block 36. It is understood that the preset clamping force range is determined in advance through experiments. By determining whether the clamping force is within the preset clamping force range, the degree of clamping of the overhead conductor by the movable clamping block 35 and the fixed clamping block 36 can be determined, thereby avoiding the situation of being too loose or too tight, and ensuring the stability of clamping the overhead conductor.

[0043] As at least one embodiment, the electronic control device 4 also includes a dual-axis motor 46 disposed inside the housing 41 and communicatively connected to the controller. Both output shafts extend out of the housing 41 and are respectively connected to the two winch assemblies 45, that is, the dual-axis motor 46 drives the two winch assemblies 45 to rotate.

[0044] In some embodiments, please combine Figures 9 to 12 , Figure 9 This is an exploded view of the outer shell and the inner casing. Figure 10 yes Figure 9 A magnified view of a section at point E in the middle. Figure 11 This is a side view of a split-type single-phase grounding device. Figure 12 yes Figure 11 A partial enlarged view at point F. The bottom of the outer casing 31 has two clamping ears 311, located near opposite ends of the casing 31. The top of the casing 41 has two openings 411 corresponding to the clamping ears 311. Two gripper mechanisms 42 are included, both communicatively connected to the controller. Both gripper mechanisms 42 are located inside the casing 41 and correspond to the two openings 411, extending from the two openings 411 respectively. Specifically, the controller controls the synchronous opening or closing of the two gripper mechanisms 42; the two gripper mechanisms 42 clamp the two clamping ears 311 when synchronously closing to connect the wire clamping device 3 and the electrical control device 4, or release the two clamping ears 311 when synchronously opening to separate the wire clamping device 3 from the electrical control device 4.

[0045] As at least one embodiment, the gripper mechanism 42 includes a servo motor 421, a cam 422, a transmission rod 423, two rotating shafts, two clamps 426, two transverse connecting rods 424, and two oblique connecting rods 425. The servo motor 421 is communicatively connected to a controller. The cam 422 is mounted on the output shaft of the servo motor 421. One end of the transmission rod 423 is rotatably connected to the base circle end of the cam 422. One end of each of the two transverse connecting rods 424 is rotatably connected to the other end of the transmission rod 423. One end of each of the two rotating shafts is spaced apart on the inner wall of the housing 41 along the sliding direction of the movable clamp 35. Both rotating shafts are perpendicular to the housing 41. The inner sidewall of 1 is located above the two transverse connecting rods 424. One end of the two oblique connecting rods 425 is rotatably connected to the other end of the two transverse connecting rods 424. The other end of the two oblique connecting rods 425 is rotatably sleeved on the end of the two rotating shafts away from the inner sidewall of the housing 41. One end of the two clips 426 is rotatably connected to the end of the two oblique connecting rods 425 sleeved on the corresponding rotating shaft. The other end of the two clips 426 extends out of the housing 41 from the corresponding opening 411. The end of the two clips 426 that connects with the corresponding oblique connecting rod 425 is provided with an arc gear 427. The arc gears 427 of the two clips 426 mesh with each other.

[0046] Understandably, the controller sends a "close" or "open" command to the servo motor 421, and the output shaft of the servo motor 421 drives the cam 422 to rotate. The base circle end of the cam 422 is rotatably connected to one end of the transmission rod 423. When the cam 422 rotates, it pushes and pulls the transmission rod 423 to perform a linear reciprocating motion. The other end of the transmission rod 423 is hinged to one end of the two transverse connecting rods 424, and the linear motion of the transmission rod 423 is converted into the oscillation of the two transverse connecting rods 424. The other end of the transverse connecting rods 424 is connected to the diagonal connecting rod. One end of the 425 is hinged, and the other end of the oblique connecting rod 425 is sleeved on the end of the rotating shaft away from the inner wall of the housing 41. When the transverse connecting rod 424 swings, it will drive the oblique connecting rod 425 to rotate around the rotating shaft. The oblique connecting rod 425 is hinged to one end of the clamp 426, and the two clamps 426 are meshed through the arc gear 427. When the oblique connecting rod 425 rotates, it will drive one side of the clamp 426 to swing, and the other side of the clamp 426 will swing in the opposite direction synchronously through gear meshing, ultimately achieving "synchronous closing" or "synchronous opening".

[0047] In some embodiments, please refer to Figures 1 to 12In addition to the structure described above, the electronic control device 4 also includes two elastic coupling parts 6. The two elastic coupling parts 6 are respectively disposed on the two opposite outer side walls of the housing 41 in the width direction and are respectively located above the two winch assemblies 45. Specifically, the elastic coupling part 6 includes a sleeve 61, a slide rod 62, a coupling joint 63, and a return spring 64. The sleeve 61 is disposed on the outer side wall of the housing 41 and arranged in the vertical direction. The slide rod 62 is slidably inserted into the sleeve 61. The coupling joint 63 is disposed at the end of the slide rod 62 away from the corresponding winch assembly 45. The return spring 64 is sleeved on the slide rod 62. One end of the return spring 64 abuts against the coupling joint 63, and the other end is fixed to the inner wall of the sleeve 61. The coupling joint 63 is used to abut against the connecting part 34 on the same side. The slide rod 62 has an axially extending rope hole. The two ends of the insulating rope 2 pass through the two through holes and the two rope holes respectively and are wound around the two winch assemblies 45 respectively.

[0048] Understandably, the elastic coupling 6, through the preload of the return spring 64, ensures that the coupling 63 continuously abuts against the connecting piece 34 on the same side, forming a flexible positioning. When the device is subjected to vibration or external disturbance, the return spring 64 can absorb the impact energy, preventing relative displacement between the wire clamping device 3 and the electrical control device 4, thus solving the problem of easy loosening of the split structure connection and making the assembly relationship between the two more stable. The rope hole of the slide rod 62 provides a precise guide channel for the insulating rope 2. Combined with the through hole design of the connecting piece 34, the transmission path of the insulating rope 2 from "wire clamping device 3 → rope hole → winch assembly 45" is completely fixed, preventing the insulating rope 2 from shifting, tangling, or rubbing against other components during the pulling process, reducing transmission resistance and wear, and improving the smoothness and service life of the winch assembly 45 driving the wire clamping device 3 to lift / move. The sliding structure of the elastic docking component 6, consisting of a sleeve 61 and a slide bar 62, does not interfere with the rope hole function of the slide bar 62. When the insulating rope 2 passes through the rope hole, it does not affect the elastic extension and retraction of the slide bar 62. The buffering effect of the return spring 64 does not hinder the transmission of the insulating rope 2. At the same time, the elastic docking component 6 is located above the winch assembly 45, and its layout avoids the core transmission components. It does not occupy key assembly space and can cooperate with the drive logic of the winch, thereby improving the overall operational stability of the device.

[0049] The above embodiments are merely preferred implementations of this application and are not the only limitation on the split-type single-phase grounding device; those skilled in the art can make flexible designs based on these embodiments and according to actual application scenarios. It is understood that, through the implementation of the above embodiments of this application, a split single-phase grounding device is constructed using an insulating rope 2, a rope frame 1, a wire clamping device 3, an electrical control device 4, and two grounding wires 5. The rope frame 1 is used to hang on an overhead conductor via a drone or an insulating rod, and the middle part of the insulating rope 2 is hung on the rope frame 1. The electrical control device 4 has a gripper mechanism 42 and two winch assemblies 45 located on opposite sides. The electrical control device 4 is detachably connected to the wire clamping device 3 via the gripper mechanism 42. The wire clamping device 3 is located above the electrical control device 4. The wire clamping device 3 has two conductive connectors 34, which are located on opposite sides of the wire clamping device 3. One end of each of the two grounding wires 5 is provided on the two connectors 34. Each of the two connectors 34 has a vertically extending through hole. The two ends of the insulating rope 2 pass through the two through holes and are wound around the two winch assemblies 45. In practical applications, the middle of the insulating rope 2 is attached to the rope frame 1, and the rope frame 1 is attached to the overhead conductor using a drone or insulating pole. Then, both ends of the insulating rope 2 are passed through the through holes on the two connectors 34 in the clamping device 3. The two ends of the insulating rope 2 are then wound around the two winch assemblies 45 in the electrical control device 4. The electrical control device 4 then controls the two winch assemblies 45 to rotate synchronously to simultaneously wind up both ends of the insulating rope 2, causing the electrical control device 4 to rise along with the clamping device 3. When the clamping device 3 rises to the overhead conductor, the electrical control device 4 controls the clamping device 3 to clamp the overhead conductor, thus lifting the rope. The overhead conductor is electrically connected to the two connecting parts 34 via the clamping device 3 (i.e., electrically connected to the two grounding wires 5 respectively provided on the two connecting parts 34). At this point, the grounding of the overhead conductor is achieved. Then, the electric control device 4 first controls the gripper mechanism 42 to open, so that the clamping device 3 is separated from the electric control device 4. Then, it controls the two winch assemblies 45 to reverse synchronously to release the two ends of the insulating rope 2 synchronously, so that the electric control device 4 descends to the ground alone, leaving only the clamping device 3 with the grounding wire 5 on the overhead conductor. After that, the two ends of the insulating rope 2 are pulled out from the two winch assemblies 45 and the two connecting parts 34 respectively, and the electric control device 4 is retrieved. Therefore, compared with the traditional solution of manually hanging the grounding wire 5 on the overhead conductor, this application realizes the automated hanging of the grounding wire 5, which saves time and effort and reduces the safety hazards caused by personnel climbing to heights. Moreover, the clamping device 3 and the electrical control device 4 adopt a separate design. When in use, only the clamping device 3 with the grounding wire 5 is left on the overhead conductor, which can effectively reduce the weight of the grounding device, reduce the load on the overhead conductor, and avoid damage to the overhead conductor due to excessive load over a long period of time.
