Problems solved by technology

[0004] However, this solution also has shortcomings. On the one hand, there is still room for optimization of the copper layer processing technology. On the other hand, the products of the surface copper plating process are more valuable and easy to be stolen. Anti-theft should be considered during construction.

Embodiment 1

[0029] Such as figure 1 , figure 2 As shown, an anti-corrosion and anti-theft type grounding electrode includes a driving head 1, a grounding rod 2, and connecting rods 3 respectively connected to the two. One end of the driving head and both ends of the grounding rod are provided with external threads, and the two ends of the connecting rod The internal thread is set, the ground rod is a steel core covered with a copper layer 4 on the surface, and the thickness of the copper layer is 0.3mm. The copper layer can be chemically formulated, clad or electroplated depending on the specific situation. From the perspective of use effect, the scheme The electroplating type is preferably used, which evenly covers the low-carbon steel core with 99.9% pure copper, so that the copper and the steel core are completely molecularly combined. The rod end of the ground rod is connected to the drill bit 5, and the outer diameter of the large end of the drill bit is larger than that of the grou...

Embodiment 2

[0036] An anti-corrosion and anti-theft type grounding electrode, the difference from Embodiment 1 is: as image 3 As shown, in this embodiment, the surface of the drill bit is designed as an inverted umbrella tower shape 7 . The inverted umbrella tower shape is a plurality of umbrella-shaped concentric circles, which are vertically combined at a certain distance from each other to form a tower-like structure. After the ground electrode is buried in the ground, the umbrella-shaped protrusion on the surface of the drill bit will hinder the upward force, which is more anti-theft than the traditional conical drill bit.

Embodiment 3

[0038] An anti-corrosion and anti-theft ground electrode, the difference from Embodiment 1 or Embodiment 2 is that in this embodiment, the connection between the ground rod and the drill bit does not use exothermic welding, but uses a connecting rod or a metal buckle; If a connecting rod is used, the upper end of the drill bit should be processed into an external thread suitable for the connecting rod; if a metal buckle is used, one end of the buckle is provided with an internal thread, which can be screwed with the grounding rod, and the other end of the buckle is set card slot. The upper end of the drill bit is processed with locking teeth, and the locking teeth can preferably be cross-shaped or I-shaped, which are compatible with the locking grooves of the buckle, so as to realize the fast clamping connection of the ground rod and the drill bit.

Abstract

The invention discloses an anti-corrosion and anti-theft grounding electrode. The anti-corrosion and anti-theft grounding electrode comprises a driving head, grounding rods and connecting rods respectively connected with the driving head and the grounding rods. External threads are arranged at one end of the driving head and the two ends of each grounding rod respectively, and internal threads are arranged at the two ends of each connecting rod. Each grounding rod is a steel core with the surface covered with a copper layer. The end of the lowermost grounding rod is connected with a drill bit. The ratio of the outer diameter of the large end of the drill bit to the outer diameter of each grounding rod is larger than 3, and the surface of the drill bit is spiral or in the shape of a parachute tower. The thickness of each copper layer ranges from 0.3 mm to 0.8 mm, the number of the grounding rods ranges from 1 to 4, and all the grounding rods are connected through the connecting rods. After the grounding electrode is driven into the ground, the gap between the grounding rod bodies and the peripheral soil wall is filled with powdery or mushy resistance reducing agents. Due to the fact that an optimized copper-clad steel technology scheme is adopted for the anti-corrosion and anti-theft grounding electrode and an anti-theft structure convenient to install and detach is adopted for assistance, not only can the anti-corrosion performance and the anti-theft performance be achieved, but also the grounding pass-through performance can be enhanced, and the anti-corrosion and anti-theft grounding electrode has the advantages of being long in service life and high in cost performance ratio.

Description

technical field [0001] The invention relates to the technical field of electric grounding devices, in particular to an anti-corrosion and anti-theft grounding electrode. Background technique [0002] The grounding electrode usually refers to a conductor or a combination of multiple conductors buried in the ground in order to be connected to the ground in the operating environment of various power facilities. Play a protective role. [0003] The preferred conditions for the development of grounding electrodes are chemical corrosion resistance and full life cycle economy. At present, the more economical and corrosion-resistant grounding electrode is selected as the grounding electrode of the copper plating process on the surface of round steel. For example, the Chinese patent application number 201220665016.0 provides a copper-clad steel grounding Both ends of the rod are provided with external threads, and the connecting ends of the steel tip and the steel cap are provi...
