[0028] like Figures 1 to 4 As shown, it is a self-traction single-phase grounding device of an embodiment of the present invention.

[0029] See also Figure 1-Figure 3 As shown, the self-traction single-phase grounding device of an embodiment of the present invention includes a shell 10, a clamping mechanism 20, a hoisting mechanism 30, a position detection mechanism 40 and a conductive member 50. The clamping mechanism 20 includes a clamping drive assembly 21, a first clamping block 22 and a second clamping block 23. The clamping drive assembly 21 is arranged on the shell 10, and is used to drive the first clamping block 22 and the second clamping block 23 to open and close to loosen or clamp the grounding ring provided on the overhead distribution line. The position detection mechanism 40 and the hoisting mechanism 30 are both arranged on the shell 10. The hoisting mechanism 30 is used to climb or descend along the traction rope arranged on the grounding ring or the overhead distribution line to move the clamping mechanism 20 toward or away from the grounding ring. The position detection mechanism 40 is used to detect the positions of the first clamping block 22 and the second clamping block 23 relative to the grounding ring. The conductive member 50 is arranged on the shell 10, the conductive member 50 is in contact with the first clamping block 22 or the second clamping block 23, and the conductive member 50 is also used to connect to the grounding wire.

[0030] The method for using the self-pulling single-phase grounding device of the embodiment of the present invention is as follows:

[0031] Connect the grounding wire to the conductive member 50, wind the traction rope laid on the grounding ring or the overhead distribution line around the hoisting mechanism 30, start the hoisting mechanism 30, and the hoisting mechanism 30 climbs along the traction rope until the position detection mechanism 40 detects that the first clamping block 22 and the second clamping block 23 have reached the grounding ring. The hoisting mechanism 30 stops climbing, and the clamping drive assembly 21 drives the first clamping block 22 and the second clamping block 23 to close to clamp the grounding ring provided on the overhead distribution line, thereby completing the grounding wire hanging operation.

[0032] Understandably, when grounding an overhead distribution line, the grounding wire is typically connected to a grounding ring pre-installed on the overhead distribution line. Of course, if it is necessary to directly connect the grounding wire to the overhead distribution line, a traction rope is laid on the overhead distribution line, and the first clamping block 22 and the second clamping block 23 are used to clamp the overhead distribution line.

[0033] It can be understood that the self-traction single-phase grounding device of this embodiment can control the hoisting mechanism 30 and the clamping mechanism 20 through a remote controller.

[0034] In this embodiment, two hoisting mechanisms 30 are provided, and the two hoisting mechanisms 30 are symmetrically arranged on both sides of the shell 10. The climbing operation is achieved by the two hoisting mechanisms 30, making the device more stable during the climbing process.

[0035] In this embodiment, the conductive member 50 is a copper busbar.

[0036] Furthermore, the conductive member 50 extends downward along the housing 10 , and the conductive member 50 is connected to the ground wire through a copper busbar fixing block.

[0037] The self-traction single-phase grounding device of the embodiment of the present invention cooperates with each other through the clamping mechanism 20, the hoisting mechanism 30, the position detection mechanism 40 and the conductive member 50. The operator only needs to connect the grounding wire with the conductive member 50 and start the hoisting mechanism 30. The device can automatically complete the operation of hanging the grounding wire, thereby enabling the operator to complete the grounding of the overhead distribution line on the ground, which is more efficient and safer.

[0038] See also Figure 1 and Figure 2 As shown, in some embodiments, exemplarily, the position detection mechanism 40 includes a trigger plate 41 and a proximity switch 42. The trigger plate 41 is slidably set on the shell 10 and is located in the clamping mouth formed by the first clamping block 22 and the second clamping block 23. The proximity switch 42 is set on the shell 10 and is located at the end of the descending stroke of the trigger plate 41. When the hoisting mechanism 30 climbs along the traction rope and the grounding ring enters the clamping mouth formed by the first clamping block 22 and the second clamping block 23, the grounding ring contacts the trigger plate 41 and causes the trigger plate 41 to slide downward. When the trigger plate 41 drops into the detection range of the proximity switch 42, the proximity switch 42 detects the presence of the trigger plate 41 and sends a signal, which can be used to stop the climbing movement of the hoisting mechanism 30. The position detection mechanism 40 detects and controls the position of the clamping mechanism 20 through the cooperation of the trigger plate 41 and the proximity switch 42, so as to ensure that the holding mechanism can subsequently perform the clamping operation on the grounding ring.

[0039] See also Figure 1-Figure 3As shown, in certain embodiments, exemplarily, the clamping drive assembly 21 includes a clamping motor 211, a motor bearing seat 212, a coupling 213, a screw 214 and a nut 215. The clamping motor 211 is mounted on the housing 10 through the motor bearing seat 212, the screw 214 is rotatably mounted on the housing 10, and the output end of the clamping motor 211 is connected to the screw 214 through the coupling 213, and the nut 215 is threadedly connected to the screw 214. The first clamping block 22 is sleeved on the nut 215, and the second clamping block 23 is mounted on the housing 10. The clamping drive assembly 21 can achieve precise position control by combining the linear motion of the screw 214 and the nut 215 and the rotational torque of the clamping motor 211. By adjusting the output of the clamping motor 211 and controlling the rotation of the nut 215, the first clamping block 22 can be precisely moved to the desired position to meet work requirements.

[0040] When the grounding ring needs to be clamped, the clamping motor 211 drives the screw rod 214 to rotate forward, and the nut 215 connected to the screw rod 214 converts the rotational motion into linear motion, driving the first clamping block 22 to move toward the second clamping block 23 to clamp the grounding ring.

[0041] When the grounding ring needs to be clamped, the clamping motor 211 drives the screw rod 214 to rotate in the opposite direction, and the nut 215 connected to the screw rod 214 converts the rotational motion into linear motion, driving the first clamping block 22 to move away from the second clamping block 23 to loosen the grounding ring.

[0042] Furthermore, the clamping drive assembly 21 also includes two guide columns 216. Both guide columns are installed on the housing 10 and are located on both sides of the screw rod 214. By setting the guide columns, the first clamping block 22 can be guided to move in a predetermined direction to avoid the clamping block from being offset or tilted, thereby improving the clamping accuracy.

[0043] Furthermore, a groove 11 is provided on the top of the shell 10, and the position detection mechanism 40, the first clamping block 22, the second clamping block 23, the screw rod 214 and the nut 215 are all arranged in the groove 11. This design allows the clamping motor 211 to be arranged in the shell 10, which can protect the clamping motor 211.

[0044] It is understandable that the clamping drive assembly 21 may also use a drive structure such as an electric push rod, a drive cylinder, etc., as long as it can realize the opening and closing movement of the first clamping block 22 and the second clamping block 23.

[0045] It is understandable that the second clamping block 23 can also be set to a movable manner, and the first clamping block 22 and the second clamping block 23 can be driven to move by two driving structures, and the opening and closing movement of the first clamping block 22 and the second clamping block 23 can also be realized.

[0046] See also Figure 1 and Figure 2 As shown, in certain embodiments, exemplarily, the self-traction single-phase grounding device further includes a pressure detection mechanism 70, the pressure detection mechanism 70 includes a pressure sensor 71 and a sensor mounting seat 72, the sensor mounting seat 72 is mounted on the housing 10, the second clamping block 23 includes a clamping portion 231 and a mounting portion 232 connected to the clamping portion 231, the mounting portion 232 is connected to the sensor mounting seat 72, the pressure sensor 71 is mounted on the sensor mounting seat 72 and connected to the clamping portion 231, the conductive member 50 is connected to the mounting portion 232, and the pressure detection mechanism 70 can monitor the pressure applied to the grounding ring by the first clamping block 22 and the second clamping block 23 in real time, and the clamping force can be adjusted according to the pressure change, thereby improving the clamping accuracy and stability.

[0047] In this embodiment, the clamping portion 231 is vertically arranged, and the mounting portion 232 is horizontally arranged.

[0048] See also Figures 1-4 As shown, in certain embodiments, exemplarily, the winch mechanism 30 includes a reel bearing seat 31, a winch cover 32, a reel assembly 33 and a winch motor 34. The reel bearing seat 31 is installed outside the shell 10, one end of the winch cover 32 is rotatably connected to the reel bearing seat 31, and the other end is connected to the reel bearing seat 31 through a lock. The reel assembly 33 is arranged in a cavity formed by the winch cover 32 and the reel bearing seat 31, and the winch motor 34 is arranged in the shell 10 and connected to the reel assembly 33. This design makes the winch mechanism 30 compact and occupies less space.

[0049] When winding the traction rope, first open the winch cover 32, wind the traction rope around the reel assembly 33, and then close the winch cover 32 and lock it.

[0050] Specifically, the hoisting motor 34 is connected to the reel assembly 33 via a converter.

[0051] It can be understood that when two hoisting mechanisms 30 are provided, only one hoisting mechanism 30 needs to be provided with a hoisting motor 34. The hoisting motor 34 is a dual-output shaft motor, which drives the two reel assemblies 33 at the same time, which is beneficial to reduce the weight and occupied space of the self-traction single-phase grounding device.

[0052] Furthermore, the reel assembly 33 includes an upper reel 331, a lower reel 332 and a connecting piece 333, and the upper reel 331 and the lower reel 332 are connected by the connecting piece 333, and a first contact surface 3311 is provided on the side of the upper reel 331 facing the lower reel 332, and the first contact surface 3311 is inclined upward in a direction away from the center of the upper reel 331, and a second contact surface 3321 is provided on the side of the lower reel 332 facing the upper reel 331, and the second contact surface 3321 is inclined downward in a direction away from the center of the lower reel 332, and a plurality of ridges 334 are provided on the first contact surface 3311 and the second contact surface 3321, and the first contact surface 3311 and the second contact surface 3321 are used to contact the traction rope, and the inclined first contact surface 3311 and the second contact surface 3321 can guide the traction rope to contact the reel and ensure that the contact area is as large as possible, thereby improving the transmission efficiency and reliability.

[0053] Optionally, weight-reducing holes 3312 are provided on both the upper reel 331 and the lower reel 332 , which is beneficial for reducing the weight of the self-traction single-phase grounding device.

[0054] See also Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, exemplarily, the winch mechanism 30 also includes a rope dividing block 35 arranged at the wire outlet of the reel assembly 33, and a guide wheel 351 and an arc-shaped guide groove 352 are provided on the rope dividing block 35. The guide wheel 351 is rotatably set on the rope dividing block 35, and a wire pressing cover 321 is also provided on the winch cover 32. The wire pressing cover 321 is located above the arc-shaped guide groove 352. The guide wheel 351 and the arc-shaped guide groove 352 are provided on the rope dividing block 35 to facilitate the climbing movement of the winch mechanism 30.

[0055] Furthermore, a buckle portion 353 is provided on the rope dividing block 35, and a slot 354 is formed on the buckle portion 353. The winch mechanism 30 also includes a locking member 36, and a through slot 361 adapted to the buckle portion 353 is provided on the locking member 36. A clamping block 362 adapted to the slot 354 is provided in the through slot 361. The clamping block 362 is clamped in the slot 354, and the locking method is simple and reliable.

[0056] See also Figure 2 As shown, in certain embodiments, exemplarily, the self-traction single-phase grounding device also includes a guide block 80 arranged on the shell 10, and the guide block 80 is arranged between the first clamping block 22 and the hoisting mechanism 30. The guide block 80 is provided with an arcuate surface, and the arcuate surface is concave to form a rope groove 81. When in use, the traction rope is placed in the rope groove 81, and then it is wound around the hoisting mechanism 30. The arcuate surface and the rope groove 81 on the guide block 80 can help the rope slide along a predetermined trajectory, thereby avoiding the rope from moving and winding during the winding process, and improving work efficiency and accuracy.

[0057] It can be understood that when two hoisting mechanisms 30 are provided, two guide blocks 80 are also provided, and the two guide blocks 80 are symmetrically arranged on both sides of the housing 10.

[0058] See also Figure 3 As shown, in certain embodiments, exemplarily, the self-traction single-phase grounding device also includes a circuit board (not shown) and a power supply 60. The circuit board and the power supply 60 are both arranged in the housing 10, and the circuit board is electrically connected to the power supply 60. The circuit board is powered by the power supply 60, and the device can more effectively control the use of electricity. When the device is in an idle state, the power supply can be automatically reduced, thereby achieving energy-saving and power-saving effects, which is conducive to reducing energy consumption costs.

[0059] See also Figure 3 As shown, in some embodiments, for example, a transverse partition 12 and a vertical partition 13 are provided inside the shell 10, and the vertical partition 13 is provided below the transverse partition 12. The interior of the shell 10 is divided into a first cavity 14, a second cavity 15 and a third cavity 16 by the transverse partition 12 and the vertical partition 13. The second cavity 15 and the third cavity 16 are located below the first cavity 14. The driving motor of the clamping mechanism 20 and the hoisting motor 34 of the hoisting mechanism 30 are provided in the first cavity 14, the circuit board is provided in the second cavity 15, and the power supply 60 is provided in the third cavity 16. By dividing the interior of the shell 10 into multiple cavities by the transverse partition 12 and the vertical partition 13, and installing different components in different cavities, direct contact between different components can be avoided, the occurrence of failures and accidents can be reduced, and it helps to improve the safety and reliability of the equipment, and it can operate more stably during operation.
