[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 11 As shown, this embodiment of the invention provides a grounding rod, which includes a fixed base 10, an insulating operating rod 20, a movable top block 30, and a movable slider 40. The fixed base 10 has a connecting groove 11 and a connecting wire connection part 12. The fixed base 10 is conductive. The insulating operating rod 20 is movably connected to the fixed base 10. The movable top block 30 is movably disposed at the opening of the connecting groove 11. The movable top block 30 has an open position for opening the opening of the connecting groove 11 and a closed position for closing the opening of the connecting groove 11. The movable slider 40 is movably disposed in the connecting groove 11. The insulating operating rod 20 and the movable slider 40 are drivenly connected to adjust the relative position of the movable slider 40 and the movable top block 30.

[0041] Using the grounding rod provided in this embodiment, the grounding wire connection part 12 of the fixed base 10 can be connected to the grounding wire, and the operator can move the grounding rod by holding the insulated operating rod 20. During wiring operations, the movable top block 30 is first placed in the open position. The component to be wired extends into the connecting groove 11 of the fixed base 10 through the opening. Then, the movable top block 30 is switched from the open position to the closed position, forming a closed structure at the connecting groove 11 to accommodate the component to be wired, creating a crucial conductive loop structure. The insulated operating rod 20 then drives the movable slider 40 to move within the connecting groove 11, adjusting the relative position of the movable slider 40 and the movable top block 30. The movable slider 40 is used to press the component to be wired, thus completing the wiring operation. Using the above structure, the fixed base 10, the movable top block 30, and the movable slider 40 work together to press the component to be wired, solving the problem in related technologies where conventional grounding rods cannot press the component to be wired.

[0042] This design enables grounding rods to perform grounding operations quickly and accurately during the maintenance and repair of electrical equipment, improving work efficiency while ensuring the safety of operators. In practice, this design allows operators to complete grounding without direct contact with electrical equipment, greatly reducing the risk of electric shock and making it suitable for various working environments.

[0043] like Figure 1 As shown, the grounding rod also includes an insulating lever 50, which extends in the same direction as the insulating operating rod 20. The lower end of the insulating lever 50 has a toggle protrusion 51, and the upper end of the insulating lever 50 is rotatably inserted into the fixed base 10 and located on the first side of the opening of the connecting groove 11. The first end of the movable top block 30 is connected to the upper end of the insulating lever 50. The insulating lever 50 can drive the movable top block 30 to rotate between an open position and a closed position. When the movable top block 30 is in the closed position, the second end of the movable top block 30 is connected to the second side of the opening of the connecting groove 11. This structure facilitates the operator in switching the position of the movable top block 30 by toggling the toggle protrusion 51, improving the accuracy and safety of the operation.

[0044] Specifically, the insulated lever design allows the operator to open and close the grounding rod while remaining away from live parts, avoiding the risk of direct contact with live equipment. It also makes operation less strenuous, effectively improving efficiency and reducing difficulty. The movable top block can be opened or closed even while wearing insulated gloves.

[0045] In this embodiment, the actuating protrusion 51 includes a connecting cylinder 511 and an actuating plate 512. The connecting cylinder is sleeved on the lower end of the insulating lever 50, and one side of the actuating plate is connected to the outer wall of the connecting cylinder. This structural design makes the operation of the actuating part more convenient, improving the ease and efficiency of operation. Specifically, the combination design of the connecting cylinder and the actuating plate not only makes the operation of the actuating part smoother, but also improves the intuitiveness and convenience of operation. The operator only needs to simply actuate the actuating plate to easily complete the opening and closing operation of the grounding rod, greatly improving the efficiency of daily maintenance of power lines.

[0046] like Figure 3 and Figure 7 As shown, a tenon and mortise structure 60 is provided between the second end of the movable top block 30 and the second side of the groove of the connecting slot 11. When the insulating lever 50 pushes the movable top block 30 upward, the movable top block 30 can be connected to the fixed base 10 through the tenon and mortise structure 60. The introduction of the tenon and mortise structure makes the connection between the movable top block and the fixed base more stable, ensuring the stability and reliability of the grounding rod.

[0047] Furthermore, since the movable top block 30 can be connected to the fixed base 10 through the tenon structure 60 when the insulating lever 50 pushes the movable top block 30 upward, and the movable top block 30 can also press the component to be wired when it moves upward, the connection between the tenon structure 60 and the fixed base 10 is more secure when the movable top block 30 moves upward.

[0048] The mortise and tenon structure not only enhances the stability of the connection, but also allows the movable top block to fit tightly against the fixed base when in the closed position, preventing loosening caused by external factors such as wind and vibration, and ensuring the continuous effectiveness and safety of the grounding operation.

[0049] like Figure 3 As shown, a snap-fit ​​groove 14 is provided on the second side of the groove opening of the connecting groove 11. When the movable top block 30 is in the closed position, the second end of the movable top block 30 can extend into the snap-fit ​​groove 14. The tenon and mortise structure 60 includes a first tenon and mortise 61 provided on the groove wall of the snap-fit ​​groove and a second tenon and mortise 62 provided on the second end of the movable top block 30. The combination of the tenon and mortise structure and the snap-fit ​​groove makes the connection between the movable top block and the fixed base more stable when the movable top block is in the closed position, thereby improving the stability and reliability of the grounding rod.

[0050] The combination of mortise and tenon structure and snap-fit ​​groove not only enhances the stability of the connection, but also effectively reduces the loosening of the connection caused by airflow, external vibration, etc., ensuring the stability and reliability of the grounding connection and reducing the occurrence of equipment failure and safety accidents.

[0051] like Figure 1 and Figure 4 As shown, the grounding rod also includes a connector 70, through which the first end of the movable top block 30 is fixedly connected to the upper end of the insulating lever 50. The use of the connector makes the connection between the movable top block and the insulating lever more flexible, facilitating the assembly and disassembly of the grounding rod.

[0052] The connector design also provides convenience for maintenance and replacement. When a part is worn or damaged, it can be quickly located and replaced without the need for complete scrapping, which reduces maintenance costs and increases the service life of the equipment.

[0053] In this embodiment, the connector 70 and the insulating lever 50 are formed by 3D printing.

[0054] like Figure 1 and Figure 2As shown, the grounding rod also includes a movable screw 80. A threaded hole 13 is provided on the fixed base 10, penetrating the bottom wall of the connecting groove 11. The movable screw 80 passes through the threaded hole 13 and is threadedly connected to the fixed base 10. The lower end of the movable screw 80 is connected to the upper end of the insulating operating rod 20, and the upper end of the movable screw 80 is connected to the movable slider 40. By rotating the insulating operating rod 20, the operator can use the movable screw 80 to drive the movable slider 40 to move relative to the movable top block 30, which has the advantage of easy operation.

[0055] like Figure 2 As shown, the grounding rod also includes a connecting bolt 90. The movable slider 40 is rotatably connected to the upper end of the movable screw 80 via the connecting bolt 90. An anti-rotation structure is provided between the movable slider 40 and the fixed base 10 to prevent the movable slider 40 from rotating relative to the fixed base 10. This design ensures the stability of the movable slider during the adjustment process, avoids accidental rotation of the movable slider during operation, and improves the accuracy and safety of the grounding operation.

[0056] Specifically, the combination of the connecting bolt and the anti-rotation structure ensures the accuracy and stability of the movable slider during the adjustment process, avoids poor grounding caused by improper operation, and ensures the normal operation of the equipment and the safety of the operators.

[0057] In this embodiment, the anti-rotation structure includes an anti-rotation groove that extends from the bottom of the connecting groove 11 towards its opening. The sidewall of the movable slider 40 engages with the anti-rotation groove to prevent rotation. The design of the anti-rotation groove ensures the stability of the movable slider during adjustment, prevents accidental rotation of the movable slider during operation, and improves the accuracy and safety of grounding operations.

[0058] In this embodiment, the grounding wire connection part 12 is a grounding wire screw 121. The design of the grounding wire screw makes the connection of the grounding wire more secure, ensuring the stability and reliability of the grounding rod.

[0059] Specifically, the use of grounding screws not only ensures the firmness of the grounding connection, but also facilitates inspection and maintenance by operators, reduces the risk of accidents caused by loose connections, and improves the safety of power equipment during maintenance.

[0060] In this embodiment, the fixed base 10, the movable top block 30, and the movable slider 40 are all made of aluminum alloy. The use of aluminum alloy not only ensures the conductivity and mechanical strength of the grounding rod, but also reduces its weight, improving the convenience and safety of operation.

[0061] Specifically, the fixed base 10, the movable top block 30, and the movable slider 40 are all surface-treated to prevent oxidation and ensure high strength.

[0062] In this embodiment, the insulating operating rod 20 is made of epoxy resin. The insulating properties of epoxy resin ensure the safety of the operator when operating the grounding rod, improving the safety and reliability of the operation.

[0063] Among them, the epoxy resin insulated operating rod not only provides excellent insulation, but also has high mechanical strength and is lightweight.

[0064] In this embodiment, the insulating lever 50 is made of insulating resin material. The use of insulating resin material further enhances the insulation performance of the insulating lever, improving the safety and reliability of operation.

[0065] Among them, the insulating lever made of insulating resin material not only has higher insulation performance, but also good weather resistance and corrosion resistance, and can work stably for a long time in harsh environments, improving the safety and reliability of grounding operation of power equipment.

[0066] In this embodiment, the wire connection part 12 is located on the second side of the groove opening of the connecting groove 11. This layout design makes it easier to connect the wires, improving the convenience and efficiency of operation.

[0067] The length of the movable screw 80 is adjustable. This adjustability improves the versatility and adaptability of the grounding rod.

[0068] In this embodiment, the insulating grounding rod fixing base 10 is manufactured using a stamping process. The use of stamping not only improves the processing accuracy and surface quality of the fixing base, but also reduces production costs.

[0069] The opening and closing angle of the movable top block 30 of the insulating grounding rod is adjustable. The adjustability of the opening and closing angle of the movable top block improves the versatility and adaptability of the grounding rod.

[0070] In this embodiment, the surface of the movable top block 30 of the insulating grounding rod is provided with anti-slip texture. The anti-slip texture increases the friction between the movable top block and the grounding wire connection part, ensuring the stability of the grounding wire connection and improving the stability and reliability of the grounding rod.

[0071] It should be noted that the inventors discovered during their work that when grounding a 380V system, they often encountered the problem of insufficient space for the grounding rod. The distance between the outgoing lines of a low-power circuit breaker is generally about 2cm. When wiring, since conventional grounding rods use a flat-mouth design with a clamp width of about 5cm or more, the clamp cannot press the circuit breaker outgoing lines tightly, or short circuits may easily occur between phases.

[0072] To address this issue, the grounding rod designed in this embodiment is adaptable to different scenarios with grounding depths of 2cm, 5cm, or greater. It allows for better, faster, and more secure grounding, reducing work time and improving efficiency compared to traditional methods. This grounding rod enhances the efficiency of maintenance personnel, simplifies workflows, and ensures their safety during construction. It provides a practical solution for low-voltage live-line work and grounding procedures, making it an essential tool for grounding operations.

[0073] The apparatus provided by the embodiments has the following beneficial effects:

[0074] (1) The grounding rod has a split structure, which is suitable for transformer distribution cabinets in multiple scenarios. It is quick to use and can be applied to multiple scenarios. It can reduce the workload of maintenance personnel, is easy to carry, and has wide applicability. It overcomes the problem of not being able to fix the grounding rod due to the small spacing between the outgoing terminals.

[0075] (2) Insulated operating rod: To ensure the safety of workers, it needs to be made of epoxy resin, which has good insulation and operability, and is high in strength and light in weight, meeting the requirements of insulation strength and rigidity, and is drop-resistant and scratch-resistant.

[0076] (3) Fixed base: Due to the small spacing between the outgoing lines of the low-power circuit breakers on site, a lightweight ring mechanism is designed to form an important conductive loop structure.

[0077] (4) Movable top block: Because the spacing between the outgoing lines of the low-power circuit breaker on site is small, the conventional C-port cannot be fitted and locked. A movable top block is designed with a notch in the ring mechanism so that the wire and outgoing terminal can be inserted. After reaching the position, it is closed. The movable slider is tightened with the target object by the insulated operating rod.

[0078] (5) The movable top block needs a transmission mechanism to control it. Design an insulating lever to control the opening and closing state of the movable top block.
