[0002] In the power system, when routinely inspecting the lines that need to be repaired, it is necessary to manually connect the grounding wires at the grounding pull rings at both ends of the construction section to achieve reliable grounding and ensure the personal safety of the workers during the construction process.

[0003] In power systems or other industrial environments, the installation and removal of grounding wires requires climbing operations, which may bring some disadvantages and challenges, mainly including the following points: First, there is a risk of falling in the climbing operation itself, especially in bad weather or unstable working platforms, the safety risk of workers is significantly increased. Second, after climbing to a certain height or when the hook device is too heavy, the flexibility and efficiency of operating the grounding wire will be significantly reduced. For example, when installing or removing the grounding wire, it may be necessary to move and adjust the position multiple times due to height and position restrictions, which increases the complexity and time-consuming operation. Third, due to the need to climb and perform accurate operations, the efficiency of the entire process is usually lower than that of operating on the ground. This will affect the maintenance and repair time of the power system or equipment, and then affect the reliability and availability of the system. Fourth, under certain environmental conditions, such as ice and snow cover or strong winds, climbing operations become more dangerous and difficult. These environmental restrictions may cause work to be suspended or delayed, affecting the timeliness of emergency repairs. Fifth, climbing operations usually require workers to have specific training and skills to ensure that they can operate and complete the work safely, increasing the cost and complexity of management and training.

[0026] The C-shaped grounding hook of the present invention can be used to hang a grounding wire on the ground. The C-shaped structure and the concave groove design cooperate with the push rod and the driving motor to realize self-locking with the aluminum rod, thereby ensuring that the grounding hook is firmly connected. The left and right pull ropes are used to realize the installation of the device on the ground. There is no need for operators to climb high to work, which reduces high-risk operations such as manual climbing and improves work efficiency.

[0027] Example 1 A C-shaped grounding hook capable of being hooked to a grounding wire 11 on the ground comprises a C-shaped hook body 7, which is formed by integrally connecting two upper and lower cross bars and a longitudinal bar to form a C-shape, wherein the two cross bars are arranged in parallel, and the two ends of the longitudinal bar are respectively connected to the two cross bars. The design of the C-shaped structure not only ensures the strength and stability of the hook, but also enables the hook to fit tightly on rods of various shapes, such as electric poles, iron towers, etc., and has a wide range of applications. A left through ring 5 and a right through ring 4 are respectively arranged on the left and right sides of the upper cross bar of the hook body 7, and the left through ring 5 and the right through ring 4 are arranged in parallel. A left pull rope 13 is connected to the right through ring 4, and a first end of the left pull rope 13 is tied to the right through ring 4, and a second end of the left pull rope 13 passes through the right through ring 4 and the left through ring 5 in sequence and then extends downward to the ground. The left through-ring 4 guides the left pull rope 13 so that the left pull rope 13 is not easy to fall off during the pulling process. The right through-ring 4 and the left through-ring 5 are fixedly connected by bolts and the upper cross bar. The right through-ring 4 is connected with the right pull rope 12. The first end of the right pull rope 12 is tied to the right through-ring 4. A through hole is opened at the hook body 7 corresponding to the right through-ring 4. The second end of the right pull rope 12 extends downward from the through hole to the ground. A driving motor 9 is arranged inside the C-shaped part of the hook body 7. The driving motor 9 is fixedly connected to the lower cross bar by bolts. A push rod 8 is connected to the output shaft of the driving motor 9. A groove is opened on the hook body 7 corresponding to the position of the push rod 8. A fixing seat is arranged at the bottom of the hook body 7, and a grounding wire 11 is fixedly installed on the fixing seat.

[0028] As a preferred example of the above embodiment, the drive motor 9 is started and stopped by an external wireless remote control. The wireless remote control allows the operator to control the start and stop of the drive motor 9 within a safe distance without directly contacting the device, thereby reducing operational risks.

[0029] As a preferred example of the above embodiment, the right pull rope 12 and the left pull rope 13 are passed through the left through ring 5 and the right through ring 4 and then fixed by a cable tie to prevent them from loosening and falling off.

[0030] As a preferred example of the above embodiment, a curved plate 6 is provided on the top of the push rod 8, which better adapts to the shape of the aluminum rod 3 and has a good fixing effect on the aluminum rod 3.

[0031] As a preferred example of the above embodiment, a rubber pad is arranged in the arc plate 6, which increases the friction between the arc plate 6 and the aluminum rod 3, prevents the aluminum rod 3 from sliding or falling out, and improves the stability and safety of the operation; in addition, the rubber pad can also play a buffering role to protect the aluminum rod 3 from damage.

[0032] As a preferred example of the above embodiment, the edges of the groove are rounded to reduce the sharpness of the edges of the groove, avoid damaging the aluminum rod 3, and make the aluminum rod 3 enter the groove more smoothly.

[0033] As a preferred example of the above embodiment, the push rod 8 is a cylinder, so that the push rod 8 can evenly distribute stress when subjected to force, thereby improving its bending and torsion resistance. In electrical operations, the push rod 8 needs to withstand certain mechanical and electromagnetic forces, and the cylindrical design can better meet this requirement.

[0034] When the hook body 7 is stuck on the aluminum rod 3, since the center of gravity of the hook body 7 is directly below the aluminum rod 3, the right pull rope 12 is pulled down to make the grounded hook body 7 rise and pass over the aluminum rod 3. The hook body 7 is buckled on the aluminum rod 3, and the bottom of the lower cross bar is a groove. The driving motor 9 controls the push rod 8 to rise and press the aluminum rod 3. After stopping, it will self-lock with the aluminum rod 3.

[0035] When in use, the operator stands on the ground and throws the right pull rope 12 over the aluminum rod 3 under the insulated wire 1 by hand, ensuring that the right pull rope 12 can accurately pass over the aluminum rod 3 and reach the predetermined position. Once the right pull rope 12 passes over the aluminum rod 3, the operator starts to pull the right pull rope 12 to drive the hook body 7 to rise. During the rising process, the operator needs to pay close attention to the position of the hook body 7 to ensure that it can smoothly clamp the aluminum rod 3. When the aluminum rod 3 enters from the opening on the right side of the hook body 7, the hook body 7 will automatically clamp the aluminum rod 3 to complete the initial hanging. The operator controls the drive motor 9 on the ground to start, driving the push rod 8 to move upward to press the aluminum rod 3 in the groove to form a firm lock. Due to the special design of the push rod 8 and the groove, the aluminum rod 3 will be firmly pressed in the groove and cannot be easily removed, ensuring the stability and safety of the grounding wire 11.

[0036] After the grounding wire 11 is hooked and locked, the operator can start the power operation. When the operation is completed, the grounding wire 11 needs to be unhooked. At this time, the driving motor 9 is controlled to drive the push rod 8 to descend. During the descent of the push rod 8, the operator needs to pay close attention to its position to ensure that it can be smoothly separated from the aluminum rod 3. Once the push rod 8 is separated from the aluminum rod 3, the operator can start to pull the left pull rope 13. The pulling of the left pull rope 13 will drive the hook body 7 to deviate to the left and make the aluminum rod 3 come out of the opening on the right side of the hook body 7. At this time, the operator needs to continue to pull the left pull rope 13 until the hook body 7 is completely lowered to the ground for the next hooking or disassembly.

[0037] Example 2 Embodiment 2 is a preferred example, in which the drive motor 9 is a screw stepper motor. When started, the output shaft of the drive motor 9 rotates, thereby driving the push rod 8 to rotate and lift. The screw stepper motor has a self-locking ability. After rotating to a certain length, its own thread and the screw can form a lock to prevent the push rod 8 from retreating.

[0038] Specifically, the output shaft of the lead screw stepper motor is directly connected to the push rod 8. When the motor receives a start signal, the output shaft rotates, which is converted into a linear lifting motion of the push rod 8 through precision thread matching. This conversion mechanism ensures that the movement of the push rod 8 is accurate and controllable. The lead screw stepper motor has a unique self-locking capability. When the motor rotates to a certain length, that is, when the push rod 8 reaches a predetermined position, the friction between the thread and the lead screw is sufficient to resist the external load, forming an effective locking mechanism. The self-locking capability prevents the push rod 8 from retreating when not acted upon by external forces, thereby enhancing the stability and safety of the system. In practical applications, the aluminum rod 3 is firmly locked when pushed to the specified position, without the need for an additional locking device, thus simplifying the system structure and reducing costs.

[0039] As a preferred example of the above embodiment, Figure 4 As shown, a support plate 14 is provided on the top of the push rod 8. Considering the radial force and axial force that may be generated by the rotation of the screw stepper motor, and its influence on the stability of the push rod 8 and the aluminum rod 3, the support plate 14 provides a stable support surface for the push rod 8, so that it can better adapt to the rotation of the motor, ensure that the aluminum rod 3 always remains firmly locked during the pushing process, enhance the overall stability and reliability of the system, and can adapt to the rotation of the screw stepper motor to keep the aluminum rod 3 locked.

[0040] As a preferred example of the above embodiment, a rubber pad is provided on the support plate 14, which increases the friction between the support plate 14 and the aluminum rod 3, prevents the aluminum rod 3 from sliding or falling out, and improves the stability and safety of the operation; in addition, the rubber pad can also play a buffering role to protect the aluminum rod 3 from damage.

[0041] Example 3 Embodiment 3 is a preferred example, in which pulleys are provided at the left and right loops to guide the left pull rope 13 so that the pulling is smoother.

[0042] Example 4 A method for installing a C-shaped grounding hook capable of being connected to a grounding wire 11 on the ground comprises the following specific steps: (1) The operator throws the right pull rope 12 over the aluminum rod 3 below the ground wire 11 clamp 2 by hand, and then pulls the hook body 7 up until the aluminum rod 3 enters from the opening on the right side of the hook body 7, and the hook body 7 clamps the aluminum rod 3; (2) Control the drive motor 9 to start, and the drive motor 9 drives the push rod 8 to move upward, pressing the aluminum rod 3 in the groove to form a lock; (3) After the work is completed, the driving motor 9 is controlled to drive the push rod 8 to descend, and the operator pulls the left pull rope 13 on the ground, and the aluminum rod 3 is released from the opening on the right side of the hook body 7. The operator continues to pull the left pull rope 13 to drive the hook body 7 to descend.

[0043] As a preferred example of the above embodiment, during the rising or falling process of the hook body 7, the left pull rope 13 and the right pull rope 12 are pulled to ensure the stability and balance of the device when it is clamped on the aluminum rod 3. During the rising or falling process of the hook body 7, the role of pulling the left pull rope 13 and the right pull rope 12 is not only to drive the movement of the hook body 7, but they can also ensure the stability and balance of the device when it is clamped on the aluminum rod 3; due to the design principle of the C-type grounding hook, when the hook body 7 is clamped on the aluminum rod 3, a certain torque and force will be generated. At this time, by pulling the left pull rope 13 and the right pull rope 12, the center of gravity and stability of the device can be adjusted to ensure that it can be firmly hung on the aluminum rod 3 without falling off or tilting.

[0044] Example 5 A method for installing a C-shaped grounding hook capable of being connected to a grounding wire 11 on the ground comprises the following specific steps: (1) The right pull rope 12 is pulled by the drone to pass over the aluminum rod 3 below the ground wire 11 clamp 2, thereby pulling the hook body 7 upward until the aluminum rod 3 enters from the opening on the right side of the hook body 7, and the hook body 7 clamps the aluminum rod 3; (2) Control the drive motor 9 to start, and the drive motor 9 drives the push rod 8 to move upward, pressing the aluminum rod 3 in the groove to form a lock; (3) After the work is completed, the driving motor 9 is controlled to drive the push rod 8 to descend, and the left pull rope 13 is pulled, so that the aluminum rod 3 is disengaged from the opening on the right side of the hook body 7, and the left pull rope 13 is continued to be pulled to drive the hook body 7 to descend.
