Description

Technical field [0001] The present invention involves a safe grounding device, which is specifically a enhanced anti -corrosion composite conductive ground device for large and medium -sized enterprises such as electricity, chemical industry. Background technique [0002] The grounding device is composed of the metal ground body buried in the soil (corner steel, flat steel, steel pipe, etc.) and the ground wire for connected.The traditional grounding device is generally welded directly on the ground body or connected to the ground body through bolts. The welding site is easy to rust. Even if the coating has an anti -corrosion layer, the ground wire will be directly welded.The anticorrosive layer loses the protection effect and reduces the service life and conductive performance of the grounding device; the method of locking the ground wire is used to lock the ground line.Poor performance and short service life.The patent number 20061009890.8 Popularly disclosed the surface treat...

AI Technical Summary

Problems solved by technology

In traditional grounding devices, the grounding wire is usually directly welded to the grounding body or connected to the grounding body via bolts. The welded part is prone to corrosion. Even if it is coated with an anti-corrosion layer, direct welding of the grounding wire will destroy the anti-corrosion layer during construction. The anti-corrosion layer loses its protective effect, which reduces the service life and conductivity of the grounding device; the grounding wire is connected by bolt locking, and the locking part is easy to loosen, which cannot effectively protect the electrical equipment. The connection is not firm, the contact surface is small, the resistance is large, and the electrical conductivity Poor performance and short service life

Patent No. 20061009890.8 discloses a surface treatment method of electroless nickel plating on steel grounding electrodes. It is nickel-plated on the surface of the grounding body. After a long time in the ground, the grounding body is prone to peeling, poor adhesion, and easy to corrode. The cost of nickel plating is relatively high. High; Patent No. 200510021757.X discloses a method of manufacturing zinc-clad steel grounding electrodes, which uses zinc-clad steel and presses it onto the steel core through a hydraulic press, but there is a gap between the zinc layer and the steel layer, and the conductive effect is not good , easy to peel off the layer, the anti-corrosion effect is not good, the service life is short, and the processing is cumbersome

An existing grounding body uses a layer of nano-carbon layer directly sprayed on the surface of the angle steel grounding body under high pressure. During the construction process, the surface of the grounding body is prone to friction, impact, and strain, so that the nano-carbon layer is worn, and the angle steel base material is exposed at the worn part, avoiding No rust corrosion and diffusion corrosion at the rusted place, the anti-corrosion effect is not ideal, affects the electrical conductivity, and the protective performance has not been fundamentally improved
