[0003] The grounding lead-out device we currently use has a basic structure including a protective cylinder, a water-stop ring, and a grounding lead-out wire. This grounding lead-out wire may encounter various situations during use, and there may be deviations between the installation position and the position of the grounding lead-out wire. As a result, the traditional grounding lead-out device does not have good adaptability, which will affect the effectiveness of the device.

[0004] Therefore, it is necessary to provide a grounding lead-out device for the grounding grid to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a grounding lead-out device for a grounding grid, which achieves the effect of tilting and adjusting the grounding lead-out wire on the lead-out device, thereby solving the problem that the lead-out device is not suitable for different working conditions.

The lead-out assembly includes a protective cylinder, and a grounding lead-out wire is provided inside the protective cylinder. The grounding lead-out wire extends out of the upper and lower positions of the protective cylinder respectively. Two sets of water-stop rings are fixedly installed on the outside of the protective cylinder. The water-stop rings are located at the upper and lower parts of the protective cylinder respectively.

The adjusting component includes a support column fixedly installed on the outside of the protective cylinder. A lead screw is threadedly connected to the support column. A throttle handle is fixedly installed on the lead screw. A support frame is rotatably connected to the bottom of the lead screw, and a roller is provided on the support frame.

[0007] Furthermore, the lead screw is tilted according to the position of the support column, and the tilted state of the lead screw gradually approaches the side of the grounding lead wire. A throttle is fixedly installed on the lead screw.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figures 1-3 As shown, this application provides a grounding lead-out device for a grounding grid, including a lead-out component 10 and an adjustment component 20 fixedly installed on the lead-out component 10. The lead-out component 10 is responsible for effectively introducing the grounding current into the ground to protect the building system from the hazards of lightning strikes and static electricity accumulation. The lead-out component 10 can be installed in the foundation and trench, etc.

[0025] When using lead-out component 10, it is necessary to install lead-out component 10 at the location of the grounding grid in order to reduce resistance. The grounding grid can be made of flat steel. The grounding grid usually needs to be designed to be installed inside the soil. A foundation will be set on the soil, and a trench of appropriate depth can be dug on the foundation. The lead-out component 10 is then vertically placed into the trench.

[0026] When external equipment experiences a leakage or other fault, the current can quickly flow into the grounding network through the lead-out component 10, thereby flowing the current into the ground and preventing electric shock to personnel and damage to equipment.

[0027] The adjustment component 20 is used to assist the components on the lead-out component 10, so that the lead-out component 10 can be adapted to different working conditions, thereby improving the working effect of the lead-out component 10 installation.

[0028] The lead-out assembly 10 includes a protective cylinder 11. When the lead-out assembly 10 is installed, the protective cylinder 11 is located in the trench of the foundation. At the same time, a steel mesh structure formed by steel bars is installed inside the foundation. The protective cylinder 11 needs to pass through the center of the steel mesh hole so that the protective cylinder 11 can be successfully installed in the foundation. The protective cylinder 11 is provided with a grounding lead 14 inside, and the grounding lead 14 extends out of the upper and lower positions of the protective cylinder 11 respectively.

[0029] The protective cylinder 11 is hollow and provides mechanical and environmental protection for the grounding lead 14, preventing it from being damaged or corroded by external forces and preventing the intrusion of external media. The inner wall of the protective cylinder 11 is filled with insulating material, such as epoxy resin, to ensure isolation and prevent the grounding lead 14 from causing a short circuit. The protective cylinder 11 prevents the grounding lead 14 located inside the foundation from contacting the steel mesh, thus ensuring the insulation between the grounding lead and the structural steel bars.

[0030] Furthermore, the grounding lead 14 itself has a certain degree of toughness. One end of the grounding lead 14 is welded and fixed to the grounding grid, and the other end is connected to the grounding terminal of the equipment. The grounding lead 14 can conduct current, thereby realizing a reliable electrical connection with the grounding grid and electrical equipment.

[0031] Two sets of water-stop rings 12 are fixedly installed on the outer side of the protective cylinder 11. The water-stop rings 12 are located at the upper and lower parts of the protective cylinder 11 respectively. The water-stop rings 12 can be welded to the outer wall of the protective cylinder 11. At the same time, the water-stop rings 12 can be made of sealing material, thereby effectively blocking the infiltration of groundwater and ensuring the overall waterproof sealing of the lead-out component 10. In addition, a sealing ring 13 is fixedly installed on the outer side of the water-stop rings 12. The sealing ring 13 can enlarge the diameter of the water-stop rings 12, so that the water-stop rings 12 can increase their effective contact area with the surrounding structure through the sealing ring 13, and can also fill tiny gaps, thereby further enhancing the waterproof sealing effect and effectively preventing groundwater from seeping along the outer wall of the protective cylinder 11.

[0032] like Figure 3 As shown, the adjustment assembly 20 includes a support column 21 fixedly installed on the outside of the protective cylinder 11. A lead screw 23 is threaded onto the support column 21, and a throttle 24 is fixedly installed on the lead screw 23. The lead screw 23 is tilted according to the position of the support column 21, and the tilt gradually approaches the grounding lead wire 14. A support frame 25 is rotatably connected to the bottom of the lead screw 23, and a roller 26 is provided on the support frame 25. The roller 26 can contact the grounding lead wire 14. When the operator operates the throttle 24 to rotate the lead screw 23, the rotation of the lead screw 23 will drive the support frame 25 and the roller 26 to move, so that the roller 26 can move in an inclined position on the grounding lead wire 14. When the roller 26 moves, it will exert a lateral force on the grounding lead wire 14, so that the angle of the grounding lead wire 14 can be adjusted by the roller 26. At this time, the angle of the grounding lead 14 will change. When encountering different installation environments such as narrow space and complex layout, or different working conditions such as the changing position of electrical equipment, the angle of the grounding lead 14 can be flexibly adjusted, so that the lead component 10 can be better adapted to different working conditions, ensuring the reliability and effectiveness of the grounding connection.

[0033] A connecting rod b27 is slidably mounted on the support column 21, and the connecting rod b27 is fixedly connected to the support frame 25. When the support frame 25 is adjusted in position by the lead screw 23, the connecting rod b27 will move synchronously on the support column 21. Thus, the connecting rod b27 can limit the roller 26, prevent it from deviating, and ensure the stability of the device operation.

[0034] Meanwhile, a bolt 28 is provided on the end of the support column 21 near the protective cylinder 11. The protective cylinder 11 has a threaded hole 29. The bolt 28 can pass through the support column 21 and be threaded into the threaded hole 29, so that the entire adjustment assembly 20 can be quickly installed or disassembled on the lead-out assembly 10, thereby facilitating the maintenance and debugging of the equipment.

[0035] During the installation of the lead-out component 10, when the two ends of the grounding lead-out wire 14 are welded to the grounding grid or the grounding terminal of the equipment, the lead-out component 10 is fixed on the foundation. At this time, the grounding lead-out wire 14 may have a slight positional deviation from the grounding grid or the grounding terminal of the equipment. By adjusting the component 20, the grounding lead-out wire 14 will bend, so that the grounding lead-out wire 14 can contact the grounding grid or the grounding terminal of the equipment, which facilitates subsequent welding. After the adjustment component 20 bends and welds the grounding lead-out wire 14, the adjustment component 20 can be removed from the lead-out component 10 through the bolt 28 and the threaded hole 29, thereby reducing the footprint of the lead-out component 10.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
