[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1

[0027] Reference Figure 1 , which is the first embodiment of the present invention, provides a one-to-N grounding pile extension tool for a plant station, and the device includes a connector 100, which is used to connect to the grounding piles used in the original plant station; an extended copper bus 200, which is used to expand the number of grounding piles; and a through-hole bolt 300, which is used to connect to the grounding wire.

[0028] Specifically, the connector 100 is cylindrical, a thread is arranged on the connector 100, the connector 100 is fixedly connected to the extended copper bus 200 by a hand-tightened nut, and the connector 100 is made of brass material.

[0029] Among them, the connector 100 is the basis of the entire device and is used to connect to the original plant grounding pile. It is designed in a cylindrical shape and has threads on its surface, which enables the connector 100 to be firmly screwed into the original grounding pile to ensure good electrical contact between the two. The connector 100 is made of brass material, which not only has excellent electrical conductivity, but also has good mechanical strength and corrosion resistance, thereby ensuring the reliability and durability of the device for long-term use. The connection between the connector 100 and the extended copper busbar 200 is completed by hand-tightening the nut. This design not only simplifies the installation process, but also facilitates subsequent maintenance and replacement.

[0030] Example 2

[0031] Reference Figure 2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the hole spacing on the extended copper busbar 200 is the same as the hole size of the grounding pile used in the original factory station, and the thickness of the extended copper busbar 200 is consistent with the thickness of the grounding pile used in the original factory station.

[0032] Furthermore, the extended copper bus 200 is provided with a plurality of holes for simultaneously extending a plurality of additional grounding pile positions. The connection method between the extended copper bus 200 and the connector 100 is a detachable connection. The holes of the extended copper bus 200 are provided with threads. The extended copper bus 200 is made of brass material and is tin-plated.

[0033] When in use, the extended copper busbar 200 solves the problem of insufficient grounding piles in the plant. Through simple installation, an original grounding pile can be expanded to multiple grounding points. The specific features of the extended copper busbar 200 are as follows:

[0034] The hole spacing on the extended copper busbar 200 is the same as the hole size of the grounding pile used in the original factory station. This means that the extended copper busbar 200 can be seamlessly connected to the existing grounding system in terms of hole location and size. This not only ensures the physical compatibility between the new and old parts, but also ensures the stability and consistency of the electrical connection, preventing potential safety hazards caused by size mismatch.

[0035] The thickness of the extended copper bar 200 is consistent with the thickness of the grounding pile used in the original plant station. This design is to maintain the uniformity and flatness of the entire grounding system and avoid problems such as local stress concentration or poor electrical contact caused by different thicknesses. In addition, the same thickness is also conducive to maintaining the overall aesthetics of the device, making it integrated with the original facilities in appearance.

[0036] The extended copper busbar 200 is provided with a plurality of holes, so that a single grounding stake can be extended to a plurality of additional grounding stake positions. When faced with the situation that the number of grounding points needs to be increased, this design can provide a flexible and efficient solution without making large-scale changes to the existing infrastructure.

[0037] The connection between the extended copper busbar 200 and the connector 100 is detachable. This design allows the user to adjust or replace the extended copper busbar 200 at any time according to actual conditions, thereby enhancing the maintainability and adaptability of the entire system. For example, after certain specific operations are completed, if an additional grounding point is no longer needed, the extended copper busbar 200 can be easily removed without affecting the function of the original grounding pile.

[0038] The hole of the extended copper busbar 200 is provided with a thread. The existence of the thread helps to firmly install the through-hole bolt 300, ensuring a good electrical connection between the ground wire and the extended copper busbar 200. The threaded connection can also provide a certain mechanical locking force, reducing the risk of loosening caused by factors such as vibration.

[0039] The extended copper busbar 200 is made of brass and is tin-plated. Brass itself has excellent electrical conductivity and certain mechanical strength, while the tin-plated layer further enhances the material's anti-oxidation and anti-corrosion capabilities, extending the service life of the device. In addition, the combination of brass and tin-plating also meets the high standards of the grounding system, ensuring long-term stable operation even in harsh environments.

[0040] Through the above design, the extended copper busbar 200 not only solves the problem of complex operation and low efficiency caused by insufficient number of grounding piles, but also achieves high compatibility with existing facilities and excellent durability through its sophisticated structure and material selection. Such a design not only simplifies the on-site construction process, but also greatly improves the convenience and safety of work.

[0041] Example 3

[0042] Reference Figures 1-2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a through-hole bolt 300 is threadedly connected to the hole position on the extended copper busbar 200, and a through hole is opened on the through-hole bolt 300.

[0043] Furthermore, the outer diameter of the through-hole bolt 300 is smaller than the inner diameter of the hole on the extended copper busbar 200 , and the through-hole bolt 300 penetrates into the hole on the extended copper busbar 200 to be connected to the ground wire.

[0044] When in use, the through-hole bolt 300 is tightly connected to the hole on the extended copper busbar 200 through threads, playing an important role in fixing and conducting current. Specifically, the design of the through-hole bolt 300 and its matching mode with the extended copper busbar 200 have the following characteristics and effects:

[0045] The through-hole bolt 300 is connected to the hole on the extended copper busbar 200 by a threaded connection. Such a design can ensure that the bolt is firmly fixed on the extended copper busbar 200, avoiding the possibility of loosening or falling off during use. The threaded connection also allows the tightening degree to be adjusted by rotating the bolt, thereby achieving the best electrical contact effect, which is crucial to ensure smooth current transmission.

[0046] A through hole is formed on the through-hole bolt 300, and the existence of the through hole allows the grounding wire to pass directly through the bolt and connect to the grounding point on the other side of the bolt. This design not only simplifies the installation process of the grounding wire, but also ensures a good contact area between the grounding wire and the bolt, thereby reducing resistance and improving conductive efficiency.

[0047] The outer diameter of the through-hole bolt 300 is slightly smaller than the inner diameter of the hole on the extended copper busbar 200, which means that the bolt can easily pass through the hole without being blocked. This size design ensures the simplicity of the assembly process and also reduces the risk of wear or other damage caused by inappropriate size. In addition, the appropriate gap also facilitates fine-tuning during the installation process to ensure that each bolt can be properly positioned in the center of the hole.

[0048] After the through-hole bolt 300 is inserted into the hole on the extended copper busbar 200, it can be fixed by tightening the nut, etc., and the ground wire can establish a stable electrical connection with the bolt through the through hole. This method effectively transfers the current from the extended copper busbar 200 to the ground wire, forming a complete conductive path. Since brass material has good electrical conductivity, this connection method can achieve efficient power transmission. At the same time, brass material also has excellent corrosion resistance, ensuring the long-term stability and reliability of the connection point.

[0049] In summary, the through-hole bolt 300 not only simplifies the installation process of the grounding system but also provides a reliable electrical connection through its well-designed structure and good cooperation with the hole position of the extended copper busbar 200. Such a design not only improves work efficiency but also provides a safer working environment for operators.

[0050] In summary, the operation process of the device is as follows: first confirm the specific location where the grounding pile needs to be added in the plant station, and prepare a one-to-N grounding pile extension tool, including components such as the connector 100, the extension copper bar 200 and the through-hole bolt 300, and screw the connector 100 into the grounding pile used in the original plant station. Since the connector 100 has threads, it can be easily tightly combined with the grounding pile. Then, tighten the nut by hand to fix the connector 100 and the extension copper bar 200 together to ensure a firm connection between the two.

[0051] Put the extended copper busbar 200 in place so that the holes on it are aligned with the connector 100. Fix the extended copper busbar 200 to the connector 100 by hand-tightening the nut. The hole spacing and size on the extended copper busbar 200 are consistent with the grounding piles used by the original factory station, ensuring the accuracy and compatibility of the installation. Insert the through-hole bolt 300 into the hole on the extended copper busbar 200. Since the outer diameter of the through-hole bolt 300 is slightly smaller than the inner diameter of the hole, it can be easily inserted. Then fix the through-hole bolt 300 to the extended copper busbar 200 by tightening the nut or other fixing methods, pass the grounding wire through the through hole on the through-hole bolt 300, and fix it with appropriate fasteners (such as nuts). In this way, the electrical connection from the extended copper busbar 200 to the grounding wire is completed. After the installation is completed, a comprehensive inspection is carried out to ensure that all parts are firmly connected and there is no looseness. If necessary, perform electrical testing to verify whether the connection is correct and reliable.

[0053] Additionally, in order to provide a concise description of exemplary embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
