Graphene grounding system
Technical Field
The invention relates to the technical field of electric power facilities, in particular to a graphene grounding system.
Background
The core rod of the grounding system in the existing market generally directly coats a layer of copper on the outer surface of a steel rod, namely a copper-clad steel structure, although the core rod with the structure achieves good electric conductivity, higher mechanical strength and good corrosion resistance, the difference of metallographic structure of a copper material and the steel material is too obvious, so that the adhesion force between a copper layer and the surface of the steel rod is insufficient, the copper layer is easy to locally fall off after being coated on the surface of the steel rod or fall off due to friction between the copper layer and soil and the like, and the service performance and the service life of the grounding system are further influenced; in addition, as the core rods of the grounding system are generally required to be driven into a wet soil layer during installation, a plurality of core rods are required to be connected together and driven into the soil layer, however, the connection mode between the core rods in the prior art mainly depends on welding and a screw locking mode in drilling, so that when an installer beats the core rods into the soil layer, the connection positions between the core rods are subjected to extremely large impact force, and the breakage of the welding positions or the breakage of the screws is easily caused in the repeated beating process, so that the success is completely eliminated, and the installation efficiency and the operation process of workers are greatly influenced.

The invention aims to provide a graphene stone grounding system which is simple in structure, reliable in use and convenient to install.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1-2, the graphene grounding system provided by the present invention includes: at least two core rods and a coated drill. As can be seen from fig. 1, the grounding system of the present embodiment includes a first core rod 1a and a second core rod 1b, and the plating drill 2 is provided with a first graphene layer, a foam anticorrosive layer, and a second graphene layer in this order from inside to outside.
The first graphene layer and the second graphene layer are both 0.2-0.5mm, and the foaming anticorrosive layer is 0.3 mm. The coated drill 2 is used for a down-ground, and performs a vertical grounding function. The graphene-based graphene is formed by spraying graphene and an organic solvent, wherein the organic solvent is a mixture of 10 parts of oleic diethanolamide, 2 parts of methyl methacrylate, 3 parts of acrylic acid, 10 parts of didecyl dimethyl ammonium bromide, 20 parts of activated carbon, 12 parts of a binder solvent, 2 parts of rare earth oxide and titanium carbide, 3 parts of graphene, 3 parts of polyacrylonitrile fiber and 30 parts of triethylene tetramine. The second graphene layer is a flexible graphene conductive film.
And a core rod joint 6 is arranged at the connecting end of the core rod and the coating drill bit 2, and the radius of the core rod joint 6 is smaller than that of the core rod. As shown in fig. 2, a plurality of convex edges 4 are arranged on the mandrel joint 3, a clamping groove 5 is arranged on the plating drill bit 2, and the convex edges 4 are clamped in the clamping groove 5.
The top end of the core rod forms an inserting rod, a plurality of convex edges are arranged on the inserting rod, a clamping groove is axially formed in the tail end of the core rod, and the convex edge of the inserting rod of any one core rod is clamped and sleeved in the clamping groove of the other core rod. The convex edge on the insertion rod is the same as the convex edge structure on the plug connector, and the clamping groove at the tail end of the plug is the same as the clamping groove structure arranged on the plating layer drill bit.
In this embodiment, since the core rod is driven by the electric hammer or the oil pick, the core rod is driven to penetrate into the soil, so that the coating drill 2 has strict structural requirements to meet the use performance. The coated drill bit 2 of the present embodiment is structured to have a round shank body with six radially outwardly extending drill walls and a shank tip, with axial slots formed between each adjacent drill wall for discharging earth.
