[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0019] Reference Figure 1-Figure 3 As shown, the present invention discloses a wireless remote control intelligent grounding device, comprising: The tower body 1 includes a tower body 11 and a cross arm 12, wherein the cross arm 12 is connected to the tower body 11 and a jumper 13 is mounted on the cross arm 12; A grounding assembly 2 includes an operating rod 21, a telescopic rod 22, and a clamping claw 23. One end of the operating rod 21 is hinged to the tower body 11, and the clamping claw 23 is provided at the other end of the operating rod 21. An electroscope 24 is provided between the clamping claws 23. One end of the telescopic rod 22 is hinged to the tower body 11, and the other end of the telescopic rod 22 is hinged to the operating rod 21. A grounding wire 25 is passed through the interior of the operating rod 21, and both ends of the grounding wire 25 are electrically connected to the clamping claw 23 and the tower body 11. The control component 3 includes a control cabinet 31 and a handheld terminal 32. A control module 33 and a wireless transmission module 34 are provided inside the control cabinet 31. The control module 33 is electrically connected to the clamping jaw 23, the electroscope 24, the wireless transmission module 34 and the telescopic rod 22 respectively; the wireless transmission module 34 is communicatively connected to the handheld terminal 32.

[0020] The power tower body 1 in the present invention serves as a supporting structure, wherein the tower body 11 serves as the main support, and the cross arm 12 is arranged on the tower body 11 for setting up the jumper 13. The grounding assembly 2 is installed on the tower body 11. Specifically, the operating rod 21 is hinged to the surface of the tower body 11. In the standby state, the operating rod 21 is set close to the tower body 11. When grounding is required, the telescopic rod 22 is extended to drive the operating rod 21 to rotate. The end of the operating rod 21 away from the tower body 11 is provided with a clamping claw 23, and an electroscope 24 is provided between the clamping claws 23. As a preferred embodiment of the present invention, the electroscope 24 is a non-contact electroscope 24. When the operating rod 21 drives the clamping claw 23 to approach the jumper 13, the electroscope 24 will detect whether the jumper 13 is energized. When the jumper 13 is detected as live, the electroscope 24 sends a signal back to the handheld terminal 32, prompting the operator to first turn off the power and retest the circuit until the electroscope 24 returns a signal that the jumper is not live. When the jumper 13 is detected as live, the clamp 23 closes and contacts the jumper 13. A grounding wire 25 is provided inside the operating rod 21. One end of the grounding wire 25 is electrically connected to the tower body 11, and the other end is electrically connected to the jumper 13 through the clamp 23, thereby grounding the jumper 13.

[0021] Reference Figure 4-Figure 5As shown, wireless communication is achieved between the wireless transmission module 34 in the control component 3 and the handheld terminal 32. After the handheld terminal 32 inputs an operation instruction, the signal is transmitted to the control module 33 via the wireless transmission module 34. The control module 33 acts as the main control, responsible for coordinating and managing the work of other modules. Among them, the control module 33 can control the opening and closing of the clamping jaw 23, and the electroscope 24 can feedback the detection results to the control module 33. The control module 33 can send instructions to the telescopic rod 22 to control the movement of the telescopic rod 22, and can also feedback the signal to the handheld terminal 32 via the wireless transmission module 34. As a preferred embodiment of the present invention, the handheld terminal 32 can be a mobile phone or tablet computer equipped with adaptive software; the telescopic rod 22 is an electric push rod, which drives the movement of the telescopic rod 22 by electrical energy; and the clamping jaw 23 is an electric clamping jaw 23, which is driven to open and close by a motor. The clamping jaw 23 is made of conductive material, so that the clamping jaw 23 can be electrically connected to the jumper 13 and the ground wire 25.

[0022] During the actual operation, the operator inputs the operation instructions through the handheld terminal 32 to control the movement of the telescopic rod 22, extend the operating rod 21, and at the same time make the open jaws 23 close to the jumper 13. The electrometer 24 between the jaws 23 tests the jumper 13. After the test is successful, the jaws 23 are closed to fix the ends of the jaws 23 on the jumper 13; finally, the jumper 13 is connected to the tower body 11 through the grounding wire 25 inside the operating rod 21, so that the jumper 13 is grounded.

[0023] The grounding device in this invention integrates electrical testing and grounding operations through remote wireless control. Operators can deploy safety measures without having to climb the tower, significantly reducing the risks of working at height while improving grounding efficiency. This provides safer and more efficient technical support for power outage inspections and maintenance of transmission lines. Its simple structure makes it easy to install, reducing the need for modifications to existing tower structures.

[0024] Furthermore, a camera device 29 is provided inside one end of the operating rod 21 close to the clamping claw 23 , and the camera device 29 is electrically connected to the control module 33 .

[0025] Specifically, the entire operating rod 21 is a hollow structure and is made of insulating material. A camera device 29 is installed at one end of the clamp 23, which can capture and identify the movements of the clamp 23. The video captured by the camera device 29 can be fed back to the handheld terminal 32 in real time. The video can be used to observe whether the clamp 23 effectively clamps the suspension wire to ensure the stability and reliability of subsequent grounding.

[0026] Furthermore, a slip ring 28 is sleeved on the outer side of the operating rod 21 , and the slip ring 28 is hinged to the telescopic rod 22 .

[0027] Specifically, during the telescopic process, the telescopic rod 22 drives the slip ring 28 to move on the operating rod 21 , thereby driving the operating rod 21 to flip.

[0028] Furthermore, a fixing groove 26 is provided on the surface of the tower body 11 on a side close to the telescopic rod 22 , and the telescopic rod 22 drives the operating rod 21 to abut against the fixing groove 26 .

[0029] Specifically, when the grounding device of the present invention is in the standby state, the telescopic rod 22 contracts, driving the operating rod 21 to be retracted and fit into one side of the tower body 11 , and the operating rod 21 is fixed by the fixing groove 26 on the surface of the tower body 11 .

[0030] Furthermore, a rain shield 27 is provided on the tower body 11 , and the rain shield 27 is provided on the top of the fixing groove 26 .

[0031] Specifically, the rain shield 27 is set at the top of the fixing groove 26. When the operating rod 21 is matched with the fixing groove 26, it can shield the end of the clamping claw 23, preventing the electroscope 24 and the camera device 29 from getting wet in rainy and snowy weather, reducing damage, corrosion, leakage and other problems caused by rain erosion, and extending their service life.

[0032] Further, refer to Figure 4 As shown, the control assembly 3 also includes a solar panel 38 and a battery 36. The battery 36 is arranged in the control cabinet 31, and the solar panel 38 is arranged on the tower body 11. The solar panel 38 is electrically connected to the battery 36, and the battery 36 is electrically connected to the telescopic rod 22 and the clamping claw 23.

[0033] The grounding device of the present invention is powered by a solar panel 38. Specifically, the solar panel 38 is mounted on the tower body 11. The solar energy generated is transmitted to a battery 36 within the control cabinet 31, where the energy is stored. During operation, the battery 36 directly powers the telescopic rod 22, driving its movement. Furthermore, the battery 36 directly powers the clamping jaw 23, controlling its movement.

[0034] Furthermore, a power supply module 37 is provided in the control cabinet 31 . The power supply module 37 is electrically connected to the battery 36 , and the power supply module 37 is also electrically connected to the control module 33 and the wireless transmission module 34 .

[0035] Specifically, the power supply module 37 is used to convert the electrical energy of the battery 36 , adjust the voltage and current, and adapt to the use of the control module 33 and the wireless transmission module 34 .

[0036] Furthermore, a storage module 35 is provided in the control cabinet 31 , and the storage module 35 is electrically connected to the control module 33 .

[0037] Specifically, the storage module 35 can record the operation data, integrate the operation data records (such as electrical test results, operation logs), support remote monitoring and data analysis, provide support for intelligent operation and maintenance, and subsequently upload the data to the cloud platform.

[0038] Reference Figure 5 As shown, this embodiment also provides a control method for a wireless remote-controlled intelligent grounding device, which is used to control the wireless remote-controlled intelligent grounding device, and includes the following steps: S1. The handheld terminal 32 sends a command to the wireless transmission module 34. The wireless transmission module 34 feeds back a signal to the control module 33. The control module 33 sends a command to the telescopic rod 22 to control the movement of the telescopic rod 22. In step S1 , the entire control process for realizing the movement of the telescopic rod 22 to control the operation lever 21 to open is as follows: the handheld terminal 32 inputs a command, the signal is transmitted to the control module 33 via the wireless transmission module 34 , and the control module 33 controls the extension of the telescopic rod 22 according to the received signal.

[0039] S2: The telescopic rod 22 extends to drive the operating rod 21 to rotate, and the control module 33 controls the clamping jaw 23 to open, so that the opened clamping jaw 23 is close to the jumper 13; In step S2, the clamp 23 is opened and controlled to be on both sides of the jumper 13. The specific control process is as follows: while the telescopic rod 22 is extended, the control module 33 controls the opening of the clamp 23, and controls the angle of the operating lever 21 according to the feedback of the video captured by the camera device 29, so that the clamp 23 is on both sides of the jumper 13.

[0040] S3, the electrometer 24 between the clamping jaws 23 tests the jumper 13 for electricity. If it is detected that the jumper 13 is not charged, the clamping jaws 23 are controlled to move and lock, so that the clamping jaws 23 are fixed on the jumper 13; if it is detected that the jumper 13 is charged, the clamping jaws 23 are controlled to move and lock after the power is cut off, so that the clamping jaws 23 are fixed on the jumper 13, and the two ends of the grounding wire are connected to the jumper and the tower body, completing the grounding action.

[0041] In step S3, after the electrical test, the jaws 23 close, bringing them into contact with the jumper 13. The specific control process is as follows: the electroscopes 24 on both sides of the jaws 23 test the jumper 13. When the electroscopes 24 detect that the jumper 13 is not energized, the electroscopes 24 feedback a signal to the control module 33, which controls the jaws 23 to close, bringing them into contact with the jumper 13, completing the grounding operation. When the jumper 13 is detected to be energized, the power is first turned off. After the electroscopes 24 feedback that the jumper 13 is not energized, the jaws 23 are controlled to close, bringing them into contact with the jumper 13, completing the grounding operation. After the inspection is completed, the jaws 23 are controlled to open through the handheld terminal 32, and the telescopic rod 22 is retracted, so that the operating rod 21 is aligned with the side of the tower body 11, and finally the operating rod 22 is locked in the fixed slot 26.

[0042] Furthermore, the present invention utilizes anti-interference communication protocols (such as LoRa, 5G private networks, or customized wireless communication modules) to ensure real-time and secure remote control. The grounding device must be adaptable to line structures of varying voltage levels (e.g., 110kV, 220kV, and 500kV) to ensure precise connection of the operating lever 21 or docking mechanism to the conductors. Furthermore, the operating lever 21 is constructed of high-strength insulating material to prevent flashovers or mechanical failures during operation. The present invention also incorporates an emergency manual operation interface within the control cabinet 31 to prevent any disruption to repairs in the event of a remote control failure.

[0043] This embodiment further provides a high-voltage power tower, comprising at least one set of the wireless remote-controlled intelligent grounding devices. The number of installed grounding devices can be increased according to the number of lines 13 .

[0044] In summary, the present invention introduces a wireless remote-controlled intelligent grounding device, control method, and high-voltage iron tower. During actual operation, the operator inputs operating instructions through the handheld terminal 32 to control the movement of the telescopic rod 22, extending the operating rod 21 and simultaneously bringing the open jaws 23 close to the jumper 13. The electrometer 24 between the jaws 23 tests the jumper 13. After the test is successful, the jaws 23 close, fixing the ends of the jaws 23 on the jumper 13. Finally, the grounding wire 25 inside the operating rod 21 connects the jumper 13 to the tower body 11, thereby grounding the jumper 13. The grounding device of the present invention achieves integrated testing and grounding operations through remote wireless control. Operators can complete the deployment of safety measures without climbing the tower, significantly reducing the risks of high-altitude operations. At the same time, grounding efficiency is improved, providing safer and more efficient technical support for power outage inspections of transmission lines. Furthermore, the device has a simple structure and is easy to install, reducing the need for modification of existing iron tower structures.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods.
