[0031] like Figures 1 to 6 As shown, it is a self-traction single-phase grounding system of an embodiment of the present invention.

[0032] See also Figure 1-Figure 4 As shown, the self-traction single-phase grounding system of the embodiment of the present invention includes a wire hanging frame 200, a self-traction single-phase grounding device 100 and a remote control (not shown in the figure), the wire hanging frame 200 is provided with a wire hanging hole 2015 and a hanging portion 2016, the wire hanging frame 200 is used to be erected on the grounding ring 400 through the hanging portion 2016, the wire hanging hole 2015 is provided with a traction rope 300, the self-traction single-phase grounding device 100 includes a shell 10, a clamping mechanism 20, a hoisting mechanism 30, a position detection mechanism 40, a conductive member 50 and a control component, the clamping mechanism 20 includes a clamping drive component 21, a first clamping block 22 and a second clamping block 23, the clamping drive component 21 is provided 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 400, the position detection mechanism The hoisting mechanism 30 and the holding mechanism 40 are both arranged on the shell 10, the traction rope 300 is wound around the hoisting mechanism 30, and the hoisting mechanism 30 is used to climb or descend along the traction rope 300 to make the clamping mechanism 20 move toward or away from the grounding ring 400. 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 400. 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 500. The control component includes a control chip (not shown) and a remote control receiving module (not shown) arranged in the shell 10. The remote control receiving module, the clamping mechanism 20, the hoisting mechanism 30 and the position detection mechanism 40 are all connected to the control chip, and the remote control is communicatively connected to the remote control receiving module.

[0033] The method for using the self-pulling single-phase grounding system of the embodiment of the present invention is as follows:

[0034] The hanging part 2016 of the hanging frame 200 is erected on the grounding ring 400 through the insulating telescopic rod, the grounding wire 500 is connected to the conductive part 50, the traction rope 300 is wound on the hoisting mechanism 30, and the hoisting mechanism 30 is started. The hoisting mechanism 30 climbs along the traction rope 300 until the position detection mechanism 40 detects that the first clamping block 22 and the second clamping block 23 have reached the grounding ring 400. 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 400 provided on the overhead distribution line, completing the hanging operation of the grounding wire 500.

[0035] As can be understood, when grounding an overhead distribution line, the grounding wire 500 is typically connected to a grounding ring 400 pre-installed on the overhead distribution line. Of course, if it is desired to directly connect the grounding wire 500 to the overhead distribution line, the traction rope 300 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.

[0036] It can be understood that the self-traction single-phase grounding device 100 of this embodiment can control the hoisting mechanism 30 and the clamping mechanism 20 through a remote controller.

[0037] 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.

[0038] In this embodiment, the conductive member 50 is a copper busbar.

[0039] Furthermore, the conductive member 50 extends downward along the housing 10 , and the conductive member 50 is connected to the ground wire 500 through a copper busbar fixing block.

[0040] The self-traction single-phase grounding system of the embodiment of the present invention cooperates with the wire hanging frame 200 and the self-traction single-phase grounding device 100. The operator only needs to connect the grounding wire 500 to the conductive member 50 and start the hoisting mechanism 30. The device can automatically complete the operation of hanging the grounding wire 500, thereby enabling the operator to complete the grounding of the overhead distribution line on the ground, which is more efficient and safer.

[0041] See also Figure 2As shown, in some embodiments, for example, the wire hanging rack 200 includes a first wire hanging body 201, a second wire hanging body 202, a connecting body 203 and a connecting column 204. The first wire hanging body 201 and the second wire hanging body 202 have the same structure. The first wire hanging body 201 includes a wire hanging portion 2011, a first support leg 2012, a second support leg 2013 and a third support leg 2014. The wire hanging portion 2011 is provided with a wire hanging hole 2015. The first support leg 2012 and the second support leg 2013 are respectively connected to the two sides of the wire hanging portion 2011. The third support leg 2014 is provided between the first support leg 2012 and the second support leg 2013, and is respectively connected to the first support leg 2012 and the second support leg 2013. The third leg 2014 is provided with a hanging line guide block 2017, and a guide hole 2018 is provided on the hanging line guide block 2017. A hanging portion 2016 is formed between the first leg 2012 and the third leg 2014. The hanging line portion 2011 of the first hanging line body 201 and the hanging line portion 2011 of the second hanging line body 202 are connected by a connecting column 204, and the first leg 2012 of the first hanging line body 201 and the first leg 2012 of the second hanging line body 202 are connected by a connecting body 203. The structure is relatively simple and easy to install and maintain. The third leg 2014 is provided with a hanging line guide block 2017, which can better guide and fix the hanging line to prevent the traction rope 300 from loosening or shifting.

[0042] In this embodiment, the connecting body 203 is arranged in a U shape.

[0043] It can be understood that the hanging portion 2016 of the wire hanging rack 200 can be mounted on the grounding ring 400 by placing the connecting column 204 of the wire hanging rack 200 on the insulating telescopic rod, and the hanging portion 2016 of the wire hanging rack 200 can be mounted on the grounding ring 400 through the insulating telescopic rod.

[0044] See also Figure 3 and Figure 5As 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 300 and the grounding ring 400 enters the clamping mouth formed by the first clamping block 22 and the second clamping block 23, the grounding ring 400 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 of the grounding ring 400.

[0045] See also Figure 3-Figure 5 As 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.

[0046] When the grounding ring 400 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 400.

[0047] When the grounding ring 400 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 400.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] See also Figure 3-Figure 5 As shown, in certain embodiments, exemplarily, the self-traction single-phase grounding device 100 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 400 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.

[0053] In this embodiment, the clamping portion 231 is vertically arranged, and the mounting portion 232 is horizontally arranged.

[0054] See also Figure 2-Figure 6As 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.

[0055] When winding the traction rope 300 , first open the winch cover 32 , wind the traction rope 300 around the reel assembly 33 , then close the winch cover 32 and lock it.

[0056] Specifically, the hoisting motor 34 is connected to the reel assembly 33 via a converter.

[0057] 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 100.

[0058] 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 300, and the inclined first contact surface 3311 and the second contact surface 3321 can guide the traction rope 300 to contact the reel and ensure that the contact area is as large as possible, thereby improving the transmission efficiency and reliability.

[0059] Optionally, both the upper reel 331 and the lower reel 332 are provided with weight-reducing holes 3312 , which is helpful to reduce the weight of the self-traction single-phase grounding device 100 .

[0060] See also Figure 3 、 Figure 4 and Figure 6As 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.

[0061] 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.

[0062] See also Figure 4 As shown, in certain embodiments, exemplarily, the self-traction single-phase grounding device 100 further includes a traction guide block 80 arranged on the shell 10, and the traction guide block 80 is arranged between the first clamping block 22 and the hoisting mechanism 30. The traction 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 300 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 traction 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.

[0063] It can be understood that when two hoisting mechanisms 30 are provided, two traction guide blocks 80 are also provided, and the two traction guide blocks 80 are symmetrically arranged on both sides of the shell 10.

[0064] See also Figure 5 As shown, in some embodiments, exemplarily, the control component also includes a power supply 61, which is disposed in the housing 10, and the control chip is electrically connected to the power supply 61. The control chip is powered by the power supply 61, 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 beneficial to reducing energy consumption costs.

[0065] See also Figure 6As shown, in some embodiments, for example, a transverse partition 12 and a vertical partition 13 are provided inside the housing 10, and the vertical partition 13 is provided below the transverse partition 12. The transverse partition 12 and the vertical partition 13 divide the interior of the housing 10 into a first cavity 14, a second cavity 15, and a third cavity 16. The second cavity 15 and the third cavity 16 are located below the first cavity 14. The drive motor of the clamping mechanism 20 and the hoisting motor 34 of the hoisting mechanism 30 are provided in the first cavity 14, the control chip is provided in the second cavity 15, and the power supply 61 is provided in the third cavity 16. By dividing the interior of the housing 10 into multiple cavities through the transverse partition 12 and the vertical partition 13, and installing different components in different cavities, direct contact between different components can be avoided, reducing the occurrence of faults and accidents. This helps to improve the safety and reliability of the equipment and enable more stable operation during operation.

[0066] See also Figure 7 As shown, an embodiment of the present invention further provides a grounding method based on the above-mentioned self-traction single-phase grounding system, comprising:

[0067] S101, placing the hanging portion 2016 of the wire hanging rack 200 on the grounding ring 400;

[0068] S102, connecting the grounding wire 500 to the conductive member 50, and winding the traction rope 300 around the hoisting mechanism 30;

[0069] S103, sending a first instruction to the control component via the remote controller to control the hoisting mechanism 30 to start;

[0070] S104. When the position detection mechanism 40 detects that the first clamping block 22 and the second clamping block 23 arrive at the grounding ring 400, the position detection mechanism 40 outputs a signal to the control component. The control component controls the hoisting mechanism 30 to close and controls the clamping drive component 21 to start, driving the first clamping block 22 and the second clamping block 23 to close to clamp the grounding ring 400, thereby completing the grounding wire 500 hanging operation.

[0071] Furthermore, the grounding method according to the embodiment of the present invention further includes:

[0072] S105: When the device is offline, a second instruction is sent to the control component via the remote control. The control component controls the clamping drive component 21 to start in reverse, driving the first clamping block 22 and the second clamping block 23 to open to release the grounding ring 400.

[0073] S106. After the first clamping block 22 and the second clamping block 23 are reset, the control component controls the hoisting mechanism 30 to open, and the hoisting mechanism 30 drives the self-traction single-phase grounding device 100 to descend, completing the removal operation of the grounding wire 500.

[0074] Furthermore, before the hanging portion 2016 of the wire hanging rack 200 is mounted on the grounding ring 400 through the telescopic rod, the following steps are performed:

[0075] Power on the self-traction single-phase grounding device 100 and enable the remote control receiving module to communicate with the remote control;

[0076] The hoisting mechanism 30 and the clamping mechanism 20 are tested by the remote control to check whether the upper line hoisting mechanism 30 and the grounding ring 400 and the clamping mechanism 20 function normally. If so, the first clamping block 22 and the second clamping block 23 are separated from each other to the open initial position;

[0077] Connect an electrical tester to the insulated telescopic rod and test the grounding ring 400 to be put on the line to determine whether there is no voltage on the overhead distribution line.

[0078] The grounding method of the embodiment of the present invention is applied to an overhead distribution line with a grounding ring 400. The grounding wire 500 of the line grounding ring 400 can be independently hung and removed before and after the line is shut down for maintenance, thereby preventing the risk of conductor voltage leakage and providing a higher level of work safety for maintenance personnel.

[0079] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
