Description

Technical Field

[0001] This utility model relates to the field of grounding electrodes, and in particular to a quick-install graphite grounding electrode. Background Technology

[0002] Grounding electrodes are indispensable safety devices in lightning protection engineering for power systems, communication facilities, and buildings, used to safely conduct fault currents or lightning currents to the ground. Traditional metal grounding electrodes (such as galvanized steel and copper-clad steel) have long faced problems such as easy corrosion and short lifespan, while graphite materials, due to their excellent corrosion resistance, high conductivity, and environmental friendliness, are gradually becoming the mainstream alternative. Existing graphite grounding electrodes mostly adopt integral casting or segmented bolted connection structures: the former, although having good conductivity continuity, suffers from fixed length, making it vulnerable to damage during transportation and unsuitable for complex terrain; the latter, although capable of segmented assembly, relies on multiple bolts for fastening, resulting in low on-site installation efficiency, and the connection points are prone to loosening due to soil stress, leading to increased contact resistance. Especially in highly corrosive soils or areas prone to high-frequency lightning strikes, the reliability of the connection structure directly affects the current discharge effect.

[0003] Studies have shown that the existing technology has the following main problems: (1) Insufficient modularity: the overall structure has a high damage rate during transportation, and local damage requires overall replacement; (2) Low installation efficiency: the segmented structure requires aligning the bolt holes layer by layer, which is difficult to operate in narrow or deep pits; (3) Poor connection stability: the bolt preload is easy to decay over time, and the lack of radial restraint between graphite columns leads to misalignment or poor contact; (4) Conductivity reliability depends on manual operation: there is a lack of active pressure maintenance mechanism for the connection interface, which is prone to decline in conductivity due to vibration or soil settlement.

[0004] Therefore, there is an urgent need for a graphite grounding electrode structure that combines rapid assembly, reliable positioning, long-lasting conductivity, and ease of transportation and maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a quick-install graphite grounding electrode to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a quick-installation graphite grounding electrode, comprising:

[0008] A grounding tip, the upper surface of which is provided with a connecting hole;

[0009] A limiting rod, wherein the limiting rod is detachably fixed inside the connecting hole;

[0010] A graphite column, wherein the graphite column is confined between the limiting rods;

[0011] A connector is detachably fixed to the top of the limiting rod, and the insertion tip, the limiting rod, the graphite column and the connector are in communication.

[0012] Preferably, both the insertion tip and the limiting rod have an electroplated layer on their surfaces.

[0013] Preferably, the connecting hole is a threaded hole, the bottom of the limiting rod is provided with an external thread, and the limiting rod is threadedly connected to the connecting hole.

[0014] Preferably, the number of connecting holes is greater than or equal to three, and they are arranged in a ring.

[0015] Preferably, a support ring is sleeved between the graphite columns.

[0016] Preferably, the outer diameter of the support ring is less than or equal to the top outer diameter of the insertion tip.

[0017] Preferably, the connector includes a pressure plate that passes through the limiting rod and is connected to the limiting rod by fastening bolts. The upper surface of the pressure plate is provided with a terminal post.

[0018] Preferably, the lower surface of the pressure plate is provided with an elastic sheet.

[0019] The present invention achieves the following beneficial technical effects compared to the prior art:

[0020] This utility model provides a quick-install graphite grounding electrode. Through a modular and detachable design of the insertion tip, limiting rod, graphite column, and connector, combined with the radial constraint and conductive link of the limiting rod, it significantly improves installation efficiency, connection stability, and conductivity reliability. The bottom of the limiting rod is threaded to the insertion tip, and the top is locked by the connector pressure plate, forming an axial constraint frame. This enables tool-free quick assembly and disassembly, reducing transportation damage and supporting partial replacement. Multiple ring-shaped limiting rods penetrate the graphite column, eliminating the risk of radial displacement, and the surface electroplating layer ensures low-resistance conductivity throughout the entire path. The support ring restricts interlayer displacement of the graphite column, and its outer diameter does not exceed the insertion tip, avoiding increased grounding resistance. The elastic sheet under the pressure plate continuously compensates for contact pressure, suppressing resistance increases caused by vibration. The terminal supports direct wire connection without additional adapters. Therefore, it fundamentally solves the problems of cumbersome installation, easy loosening, and high maintenance costs of traditional grounding electrodes. Attached Figure Description

[0029] This embodiment provides a quick-install graphite grounding electrode, such as Figure 1As shown, it includes:

[0030] The grounding tip 1 has a connection hole 2 on its upper surface, which can be effectively inserted into the underground soil to ensure the stability of the grounding electrode.

[0031] Limiting rod 3 is detachably fixed in the connecting hole 2 and mainly serves to limit movement.

[0032] The graphite column 4 is located between the limiting rods 3. The graphite column 4 adopts a multi-segment combination design. Since a single graphite column is relatively brittle, it is easy to break when inserted into the ground. The limiting rods 3 provide external support and limit it. By stacking and splicing multiple graphite column segments 4, the above problem can be effectively solved. It should be understood that the graphite column 4 and the limiting rods 3 are in contact to ensure good conductivity.

[0036] In one implementation, there are four connecting holes 2 arranged in a ring to form an effective limit.

[0037] In one implementation, a support ring 6 is sleeved between the graphite columns 4, which can serve to support the limiting rod 3.

[0038] As one implementation, the outer diameter of the support ring 6 is less than or equal to the top outer diameter of the insertion tip 1 to avoid generating resistance when inserted into the ground.

[0039] In one embodiment, the connector 5 includes a pressure plate 51, which is disposed through the limiting rod 3 and connected to the limiting rod 3 by a fastening bolt 52. The upper surface of the pressure plate 51 is provided with a terminal block 53, through which a grounding wire is connected to achieve conductivity.

[0040] As one implementation, the lower surface of the pressure plate 51 is provided with an elastic sheet 54. When the fastening bolt 52 is tightened, the elastic sheet 54 will exert continuous pressure on the graphite column 4, thereby ensuring the conductivity effect.
