Description

Technical Field

[0001] This utility model relates to the field of grounding grid technology, and in particular to a grounding grid connection device. Background Technology

[0002] A grounding grid is a general term for a grounding body consisting of multiple metal grounding electrodes buried at a certain depth underground and interconnected by conductors to form a mesh structure. It is widely used in many industries such as power, construction, computers, mining, and communications, serving functions such as safety protection and shielding.

[0003] The prior art discloses a grounding grid connection device (201620295256.4), which includes a first grounding electrode and a second grounding electrode connected by bolts and nuts. The surfaces of the first grounding electrode, the second grounding electrode, the bolts, and the nuts are all deposited with nickel-based titanium nitride metal ceramic layers. By using a vapor deposition method, a metal ceramic material anti-corrosion coating is added to the grounding conductor connection and the surface of the bolts and nuts, thereby improving the anti-corrosion performance and service life of the substation grounding grid and the overhead line grounding electrode. However, there are still some shortcomings. The anti-corrosion coating is damaged when the grounding electrode is welded, and the anti-corrosion coating of the grounding electrode is also damaged during the twisting of the nut and bolt during the connection process, which affects the service life of the grounding electrode.

[0004] Therefore, a grounding grid connection device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a grounding grid connection device that enables rapid installation of two grounding bodies, prevents damage to the plating of the grounding bodies during installation, and improves the corrosion resistance of the grounding grid.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a grounding grid connection device, comprising:

[0007] The mounting section is located at the connection between the first grounding electrode and the second grounding electrode, and is used to connect the first grounding electrode and the second grounding electrode.

[0008] The clamping part is slidably disposed on the mounting part, and applies pressure to the connection between the first grounding body and the second grounding body located inside the mounting part, so that the two are fixedly connected;

[0009] The clamping part is located on the mounting part and is used to limit the clamping part after it has been fixed and adjusted.

[0010] Furthermore, the end of the mounting part is provided with a sealing frame for mounting the first grounding body and the second grounding body, and the inner bottom of the mounting part is provided with a sealing gasket.

[0011] Furthermore, the clamping part includes a pressure plate movably disposed on the mounting part, and the bottom of the pressure plate is provided with a pressure post for clamping the first grounding body and the second grounding body;

[0012] The mounting section has a groove inside that is adapted to the pressure plate;

[0013] The pressure plate is I-shaped.

[0014] Furthermore, the clamping part includes symmetrical support plates disposed on both sides of the pressure plate, and each of the two support plates is provided with a first helical tooth plate;

[0015] The clamping part also includes a second helical tooth plate disposed in the mounting part and corresponding to the first helical tooth plate;

[0016] The locking part also includes an elastic locking mechanism, which is used to control the locking or unlocking of the second helical tooth plate and the first helical tooth plate.

[0017] Furthermore, the elastic locking mechanism includes a guide rod connected to the second helical tooth plate, one end of which extends outside the mounting portion and is provided with a disc;

[0018] A spring is provided between the disc and the mounting part, which is sleeved on the guide rod. The spring is used to engage and lock the second helical tooth plate with the first helical tooth plate when no external force is applied.

[0019] Furthermore, the clamping part includes a limiting block rotatably disposed on the outer wall of the mounting part, and the limiting block is used to rotate and support the disc, so that the second helical tooth plate and the first helical tooth plate are in an unlocked state.

[0020] Furthermore, the mounting section is provided with a stepped groove for sliding the sealing support plate.

[0021] The beneficial effects of this utility model are reflected in:

[0022] This invention involves installing a first grounding body and a second grounding body inside the mounting section. The first and second grounding bodies are interlocked and sealed by two sealing frames. A pressure plate moves on the mounting section, pressing the first and second grounding bodies against it. Simultaneously, support plates on both sides of the pressure plate slide and seal within stepped grooves on the mounting section. A first helical toothed plate on the support plate presses against a second helical toothed plate, which in turn applies a thrust to a guide rod, a disc, and a spring. The first helical gear slides downwards on the second helical gear. When the pressure column on the pressure plate presses firmly against the first and second grounding bodies, the spring and guide rod push the second helical toothed plate against the teeth on the first helical toothed plate. The two grounding electrodes are engaged together, and because the planes of the first and second helical tooth plates fit together, the second helical tooth plate cannot move up or down, preventing the first helical tooth plate from moving upwards. This presses the first and second grounding electrodes firmly into the mounting part. When disassembly is required, the disc and guide rod are pulled, and at the same time, the limiting block is rotated so that the limiting block abuts against the disc and the mounting part. The guide block drives the second helical tooth plate away from the first helical tooth plate, causing the second helical tooth plate and the support plate to move upwards, and causing the pressure column to move away from the first and second grounding electrodes. This allows for the disassembly and installation of the first and second grounding electrodes on the mounting part, enabling rapid installation of the two grounding electrodes, preventing damage to the plating of the grounding electrodes during installation, and improving the corrosion resistance of the grounding grid.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0035] Please see Figure 1-5 This utility model discloses a grounding grid connection device, comprising:

[0036] The mounting part 1 is provided at the connection between the first grounding body 2 and the second grounding body 3, and is used to connect the first grounding body 2 and the second grounding body 3. The two ends of the mounting part 1 are provided with grooves for installing the first grounding body 2 and the second grounding body 3, so as to facilitate the installation of the first grounding body 2 and the second grounding body 3 by the mounting part 1.

[0037] The clamping part 4 is slidably disposed on the mounting part 1 and applies pressure to the connection between the first grounding body 2 and the second grounding body 3 located inside the mounting part 1 to fix the two in place.

[0038] The clamping part 5 is provided on the mounting part 1 and is used to limit the clamping part 4 after it has been fixed and adjusted.

[0039] During use, the clamping part 4 slides on the mounting part 1 to press and install the first grounding body 2 and the second grounding body 3 on the mounting part 1, preventing the first grounding body 2 and the second grounding body 3 from detaching.

[0040] like Figure 2 As shown in the specific embodiment, the end of the mounting part 1 is provided with a sealing frame 12 for mounting the first grounding body 2 and the second grounding body 3. The inner bottom of the mounting part 1 is provided with a sealing gasket 13. The sealing frame 12 is located on the groove of the mounting part 1. The sealing frame 12 is used to seal the first grounding body 2 and the second grounding body 3 inserted on the mounting part 1. There are two sealing frames 12. The sealing gasket 13 is used to support the first grounding body 2 and the second grounding body 3.

[0041] like Figure 2 and Figure 5 As shown, in one embodiment, the pressing part 4 includes a pressure plate 41 movably disposed on the mounting part 1. The bottom of the pressure plate 41 is provided with a pressure post 42 for pressing the first grounding body 2 and the second grounding body 3. The number of pressure posts 43 is multiple.

[0042] The mounting part 1 has a sliding groove that matches the pressure plate 41, and the pressure plate 41 slides and seals on the mounting part 1;

[0043] The pressure plate 41 is I-shaped.

[0044] During use, the pressure plate 41 slides on the mounting part 1, and the pressure plate 41 drives the pressure column 42 to press the first grounding body 2 and the second grounding body 3 on the top of the sealing gasket 13 on the mounting part 1.

[0045] like Figures 3-5 As shown in the specific embodiment, the clamping part 5 includes support plates 51 that are symmetrically arranged on both sides of the pressure plate 41. Each of the two support plates 51 is provided with a first inclined tooth plate 52, and the support plates 51 are used to support the first inclined tooth plate 52.

[0046] The clamping part 5 also includes a second oblique tooth plate 53 disposed in the mounting part 1 and corresponding to the first oblique tooth plate 52. The first oblique tooth plate 52 and the second oblique tooth plate 53 clamp each other to limit the support plate 51 and the pressure plate 41 in the mounting part 1, and the pressure column 42 on the pressure plate 41 presses the first grounding body 2 and the second grounding body 3.

[0047] The locking part 5 also includes an elastic locking mechanism, which is used to control the locking or unlocking of the second helical tooth plate 53 and the first helical tooth plate 52.

[0048] like Figures 3-5 As shown, in one embodiment, the elastic locking mechanism includes a guide rod 54 connected to the second helical toothed plate 53. One end of the guide rod 54 extends to the outside of the mounting part 1 and is provided with a disc 55. The guide rod 54 is slidably disposed with the mounting part 1. The guide rod 54 is used to drive the second helical toothed plate 53 to approach or move away from the first helical toothed plate 52, and the second helical toothed plate 53 limits the upper and lower positions of the first helical toothed plate 52.

[0049] A spring 56 is provided between the disc 55 and the mounting part 1, which is sleeved on the guide rod 54. The spring 56 is used to make the second helical tooth plate 53 engage and lock with the first helical tooth plate 52 when no external force is applied. The tension of the spring 56 itself drives the disc 55 and the guide rod 54 to move closer on the mounting body 1, and the guide rod 54 drives the second helical tooth plate 53 to press the first helical tooth plate 52.

[0050] In a specific embodiment, the locking part 5 includes a limiting block 57 rotatably disposed on the outer wall of the mounting part 1, and the limiting block 57 is used to rotate and support the disc 55, so that the second helical tooth plate 53 and the first helical tooth plate 52 are in an unlocked state.

[0051] When it is necessary to disassemble the first grounding body 2 and the second grounding body 3 during use, the limiting block 57 rotates on the mounting part 1. The limiting block 57 supports the pulled disc 55 and guide rod 54, preventing the disc 55 and guide rod 54 from pressing the second helical tooth plate 53 and the first helical tooth plate 52 under the tension of the spring 56. This frees up the hand to pull the pressure plate 41 and allows the pressure column 42 to move away from the first grounding body 2 and the second grounding body 3, making disassembly and installation convenient and preventing corrosion at the first grounding body 2 and the second grounding body 3.

[0052] In one embodiment, the mounting part 1 is provided with stepped grooves for sliding and sealing the support plate 51. The stepped grooves on both sides of the mounting part 1 are used to slide and seal the support plate 51.

[0053] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0054] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
