Description
Technical Field
[0001] This utility model relates to the field of grounding technology, specifically a flexible graphite horizontal grounding electrode and vertical grounding electrode connector. Background Technology
[0002] In power grounding systems, vertical grounding electrodes are typically cylindrical, while flexible graphite horizontal grounding electrodes are flat. Traditional grounding electrode connectors can generally accommodate connections between two grounding electrodes of similar or identical shapes, but they often cannot adequately meet the requirements of connections with such different shapes. This can lead to problems such as inconvenient installation and poor connection stability. Therefore, when connecting a vertical grounding electrode to a flexible graphite horizontal grounding electrode, reliable fixing and electrical connection are difficult to achieve, affecting the overall performance of the grounding system. Utility Model Content
[0003] The present invention aims to provide a connector for a flexible graphite horizontal grounding electrode and a vertical grounding electrode, so as to improve the stability and reliability of the connection between the flexible graphite horizontal grounding electrode and the vertical grounding electrode.
[0004] To solve the above technical problems, the specific solution adopted by this utility model is as follows: a flexible graphite horizontal grounding body and vertical grounding body connector, including a cylindrical part and a flat part, the flat part being vertically fixed to one end of the cylindrical part, and the other end of the cylindrical part being provided with a threaded section for connecting the vertical grounding body.
[0005] A fixing clip is provided on the flat part, and a wedge-shaped hole is provided on the fixing clip for inserting a flexible graphite horizontal grounding body, and a wedge-shaped block is provided to cooperate with the wedge-shaped hole.
[0006] As a further optimization of the above technical solution, the flat part is a strip plate.
[0007] As a further optimization of the above technical solution, the flat part includes a fixing plate and a connecting plate that are perpendicular to each other. The fixing clamp is set on the fixing plate, and the connecting plate is fixedly connected to one end of the cylindrical part.
[0008] As a further optimization of the above technical solution, the wedge-shaped hole is a through hole that penetrates the fixing clamp, with the small-diameter end of the wedge-shaped hole facing the cylindrical part.
[0009] As a further optimization of the above technical solution, the fixing clamp includes two vertical plates spaced apart and a horizontal plate connected to the upper part of the two vertical plates. Both vertical plates are fixedly connected to the flat part and located on the same side of the flat part. The inner side of the horizontal plate is an inclined surface.
[0010] As a further optimization of the above technical solution, a locking bolt capable of extending into a wedge-shaped hole is rotatably installed on the vertical plate.
[0011] As a further optimization of the above technical solution, a locking groove is provided on the wedge block for the insertion of a locking bolt.
[0012] As a further optimization of the above technical solution, the locking groove is a strip-shaped groove parallel to the surface of the flat part.
[0013] As a further optimization of the above technical solution, the locking groove is a T-shaped groove, and a circular sliding plate is vertically fixed to the inner end of the locking bolt. The width of the locking groove is greater than the diameter of the locking bolt and less than the diameter of the circular sliding plate, and the depth of the locking groove is greater than the thickness of the circular sliding plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model sets up a cylindrical part and a flat part that are vertically fixed and connected. The cylindrical part and the flat part are generally L-shaped. The threaded section of the cylindrical part is used to insert into the threaded hole at the upper end of the vertical graphite electrode to achieve threaded connection with the vertical graphite electrode. The flat part clamps the flat flexible graphite grounding body with a fixing clamp, thereby realizing reliable fixing and electrical connection between the flexible graphite horizontal grounding body and the vertical grounding body.
[0016] 2. In this utility model, the small-diameter end of the wedge-shaped hole faces the cylindrical part, and the large-diameter end of the wedge-shaped hole serves as the entrance for inserting the flexible graphite horizontal grounding body into the wedge-shaped hole. On the one hand, this facilitates the insertion of the flexible graphite horizontal grounding body into the wedge-shaped hole. On the other hand, after the flexible graphite horizontal grounding body is inserted into the wedge-shaped hole, when the wedge-shaped block presses the flexible graphite horizontal grounding body tightly, the wedge-shaped block gradually moves from the large-diameter end of the wedge-shaped groove to the small-diameter end. This can, to a certain extent, drive the flexible graphite horizontal grounding body to move towards the small-diameter end of the wedge-shaped hole, preventing the flexible graphite horizontal grounding body from falling out of the wedge-shaped hole during the pressing process.
[0017] 3. By creating a locking groove on the wedge block for the insertion of the locking bolt, the locking bolt can further fix the wedge block inserted into the wedge hole. The locking groove is set as a strip groove parallel to the surface of the flat part. Compared with setting multiple circular locking grooves, this avoids the problem of the locking bolt and the circular locking groove not being accurately aligned due to different depths of the wedge block inserted into the wedge hole. This allows the locking bolt to be inserted into the strip groove at any time.
[0018] 4. By setting the locking groove as a T-shaped groove, the circular sliding plate fixed to the inner end of the locking bolt can slide in the T-shaped groove, which can keep the wedge block always in the wedge hole, making it convenient for the connection to be transported and stored before use.

[0025] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art.
[0026] Example 1
[0027] like Figure 1 As shown, this utility model discloses a connector for a flexible graphite horizontal grounding electrode 5 and a vertical grounding electrode 9, including a cylindrical part 1 and a flat part 2. The cylindrical part 1 is a metal cylinder, and the flat part 2 is a metal strip. The flat part 2 is vertically fixed to one end of the cylindrical part 1. In this embodiment, the flat part 2 is vertically fixed to one end of the cylindrical part 1 by welding, and the cylindrical part 1 is also located at the end of the strip, making the flat part 2 and the cylindrical part 1 L-shaped. The end where the cylindrical part 1 and the flat part 2 are fixed is the connecting section 101, and the other end of the cylindrical part 1 is provided with a threaded section 102 for connecting the vertical grounding electrode 9. In use, the cylindrical part 1 is vertically downward and coaxial with the vertical grounding electrode 9, and the flat part 2 is horizontal, which facilitates connection with the flexible graphite horizontal grounding electrode 5.
[0028] A fixing clip 3 is provided on the flat part 2. The fixing clip 3 includes two vertical plates 301 spaced apart and a horizontal plate 302 connected to the upper end of the two vertical plates 301. The two vertical plates 301 are fixedly connected to the flat part 2 and located on the same side of the flat part 2. The inner surface of the horizontal plate 302 is inclined. The two vertical plates 301, the horizontal plate 302 and the flat part 2 together form a wedge block 6 for the insertion of the flexible graphite horizontal grounding body 5, and a wedge block 6 is provided to cooperate with the wedge hole 4.
[0029] In this embodiment, both vertical plates 301 are rectangular plates with identical length, width, and thickness. The length direction of both vertical plates 301 is aligned with the length direction of the flat portion 2. The two vertical plates 301 are fixed to the two long edges of the flat portion 2, with their lower edges flush with the lower surface of the flat portion 2 and their upper edges extending beyond the upper surface of the flat portion 2, so that both vertical plates 301 are located on the upper side of the flat portion 2 and are distributed in parallel. A horizontal plate 302 is fixed between the two vertical plates 301 and located above them. The upper surface of the horizontal plate 302 is flush with the upper edge of the vertical plates 301, and its lower surface is an inclined plane.
[0030] In other embodiments of this utility model, the two vertical plates 301 are directly fixed to the upper surface of the flat part 2.
[0031] The wedge-shaped hole 4 is a through hole that passes through the fixing clamp 3, with the small-diameter end of the wedge-shaped hole 4 facing the cylindrical part 1. The large-diameter end of the wedge-shaped hole 4 is the entrance for inserting the flexible graphite horizontal grounding body 5. This arrangement facilitates the insertion of the flexible graphite horizontal grounding body 5 into the wedge-shaped hole 4. Furthermore, after the flexible graphite horizontal grounding body 5 is inserted into the wedge-shaped hole 4, when the wedge-shaped block 6 presses the flexible graphite horizontal grounding body 5 together, the wedge-shaped block 6 gradually moves from the large-diameter end of the wedge groove to the small-diameter end. This can, to a certain extent, drive the flexible graphite horizontal grounding body 5 towards the small-diameter end of the wedge-shaped hole 4, preventing the flexible graphite horizontal grounding body 5 from falling out of the wedge-shaped hole 4 during the pressing process.
[0032] The two vertical plates 301, the horizontal plate 302, and the wedge block 6 are all made of non-metallic materials. The vertical plates 301 and 302, and the vertical plate 301 and the flat part 2 are fixedly connected by welding. One end of the connector described in this utility model presses the flexible graphite horizontal grounding body 5 against the surface of the flat part 2 through the wedge block 6, and the other end is threaded to the upper end of the vertical grounding body 9, which can realize a stable electrical connection between the flexible graphite horizontal grounding body 5 and the vertical grounding body 9.
[0033] As another configuration of the flat part 2, the flat part 2 includes a fixing plate 201 and a connecting plate 202 that are perpendicular to each other. The fixing plate 201 is a strip plate, and the fixing clip 3 is disposed on the fixing plate 201. The connecting plate 202 is fixedly connected to one end of the cylindrical part 1.
[0034] In use, first check whether the threaded hole at the upper end of the vertical grounding body 9 is intact and whether the connection part of the flexible graphite horizontal grounding body 5 is flat and free of impurities. Then, align the threaded section 102 of the cylindrical part 1 with the threaded hole at the upper end of the vertical grounding body 9, and slowly rotate the cylindrical part 1 to make it tightly threadedly connected with the vertical grounding body 9. Then, insert the flexible graphite horizontal grounding body 5 from the large-diameter end of the wedge-shaped hole 4. Since the flexible graphite grounding body is made of flexible material, it can be finely adjusted horizontally during insertion so that the flexible graphite grounding body is located on the upper surface of the flat part 2 and aligned with the axis of the wedge-shaped hole 4. Then, insert the wedge block 6 from the large-diameter end of the wedge-shaped hole 4. As the wedge block 6 is inserted, it will gradually squeeze the flexible graphite horizontal grounding body 5, pressing it tightly against the upper surface of the flat part 2, thus fixing the flexible graphite horizontal grounding body 5 in the wedge-shaped hole 4.
[0035] Example 2
[0036] This embodiment has the same overall structure as Embodiment 1. The difference is that in this embodiment, the fixing clamp 3 is provided with a locking bolt 8 that can extend into the wedge hole 4 to lock the wedge block 6, so as to further improve the stability of the connection between the flexible graphite horizontal grounding body 5 and the vertical grounding body 9.
[0037] Two locking bolts 8 are provided and are respectively rotated through the two vertical plates 301 of the fixing clamp 3. After the wedge block 6 is inserted into the wedge hole and the flexible graphite horizontal grounding body 5 is pressed, the locking bolts 8 are rotated so that their inner ends abut against the side wall of the wedge block 6 to further tighten the wedge block 6 and improve the stability of the wedge block 6 in the wedge hole.
[0038] The wedge block 6 has a locking groove 7 for inserting a locking bolt 8. The locking bolt 8 is inserted into the wedge groove to further fix the wedge block 6 inserted into the wedge hole 4. The locking groove 7 consists of multiple spaced circular grooves, which are arranged in a row parallel to the surface of the flat part 2.
[0039] In this embodiment, the locking groove 7 is a strip-shaped groove parallel to the surface of the flat part 2. Since the wedge block 6 is located at different depths in the wedge hole 4 after the flexible graphite horizontal grounding body 5 is pressed, compared with the method of setting multiple circular locking grooves 7, the problem of the locking bolt 8 and the circular locking groove 7 not being able to be precisely aligned due to the different depths of the wedge block 6 inserted into the wedge hole 4 is avoided, so that the locking bolt 8 can be inserted into the strip-shaped groove at any time.
[0040] Example 3
[0041] This embodiment has the same overall structure as Embodiment 2, the difference being that in this embodiment,
[0042] The locking groove 7 is a T-shaped groove. A circular sliding plate is vertically fixed to the inner end of the locking bolt 8. The width of the locking groove 7 is greater than the diameter of the locking bolt 8 but smaller than the diameter of the circular sliding plate, and the depth of the locking groove 7 is greater than the thickness of the circular sliding plate. The circular sliding plate fixed to the inner end of the locking bolt 8 can slide within the T-shaped groove, ensuring that the wedge block 6 remains within the wedge hole 4, preventing separation of the wedge block 6 from the wedge hole 4. This facilitates the transfer and storage of the connector before use. It reduces the possibility of the connector becoming unusable due to the loss of the wedge block 6, lowering maintenance costs and usage risks.
[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
