Anti-corrosion and anti-theft grounding electrode

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...

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.
