Description
Technical field
The utility model relates to a kind of safety grounding device, specifically is large and medium-sized enterprise's electric equipment and the lightning-arrest enhancement type anti-corrosion composite conductive grounding devices of building such as a kind of electric power, chemical industry.
Background technology
Earthing device is to be made of with the earth connection that is connected usefulness the metal earth electrode of imbedding in the soil (angle steel, band steel, steel pipe etc.).Traditional earthing device generally is earth connection to be directly welded on the earth electrode or through bolt be connected with earth electrode, the easy corrosion of weld, even be coated with anticorrosive coat, directly the welding earth connection can destroy anticorrosive coat in construction, the anticorrosive coat of weld loses protective effect, reduces the useful life and the electric conductivity of earthing device; Adopt bolt locking to connect the mode of earth connection, locking place is easily loosening, can not effectively protect electric equipment, connects insecurely, and contact-making surface is little, and resistance is big, poor electric conductivity, useful life weak point.The patent No. 20061009890.8 disclosed a kind of steel earthing pole chemical nickel-plating surface processing methods are at the earth electrode plating nickel on surface, earth electrode in the underground time permanent after easy peeling stripping layer, poor adhesive force corrode easily, and the nickel plating cost is higher; The disclosed a kind of method of making zinc-coated grounded pole of patent No. 200510021757.X is to adopt zinc Baogang, covers on the steel core by hydraulic press, but zinc layer and steel electricity interlayer have the slit, and conductive effect is not good, easily shells pull-up and falls, antiseptic effect is bad, and useful life is short, processes loaded down with trivial details.Existing a kind of earth electrode is to adopt on angle steel earth electrode surface directly high pressure painting one deck nanometer carbon-coating, the earth electrode surface easily rubs, clashes into, pulls in work progress, make the wearing and tearing of nanometer carbon-coating, fray angle steel base material is exposed, keep away the diffusion corrosion of unavoidable corrosion and corrosion place, antiseptic effect is undesirable, influences electric conductivity, and barrier propterty is not improved at all.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model has provided that a kind of contact-making surface is big, and resistance is little, conducts electricity very well, anticorrosion durable enhancement type anti-corrosion composite conductive grounding device.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of enhancement type anti-corrosion composite conductive grounding device, comprise earth electrode and earth connection, earth electrode is angle steel or cylindrical steel, technical characterstic is that conductive grounding device also comprises connecting line and erection joint, connecting line is " L " shape, the angle steel that " L " shape minor face of connecting line is welded in earth electrode simultaneously go up or cylindrical outer wall on, the long limit of " L " shape that makes connecting line is perpendicular to angle steel one side or cylindrical outer wall, and connecting line connects earth connection through erection joint locking.
Further, described connecting line connects earth connection or connects earth connection perpendicular to the connecting line direction through the erection joint horizontal direction.
Again further, described earth electrode, earth connection, connecting line, erection joint surface soaking are soaked with the zinc layer, apply one deck combined anti-corrosion layer on the zinc layer again, and described combined anti-corrosion layer comprises nano-sized carbon and the synthetic layer structure of nano-silver conductive material.
After adopting above technical scheme, the beneficial effect that the utility model reaches is: in metal earth electrode and earth connection and the connecting line that both are fixedlyed connected, erection joint all is in the metallic substrate surface hot dipping one deck zinc layer to be arranged, by the protective layer of zinc layer as base material, guaranteed electric conductivity, can prevent that again substrate surface from getting rusty; On the zinc layer, apply by nano-sized carbon and the synthetic combined anti-corrosion layer of Nano Silver, acidproof, salt tolerant, alkaline-resisting, antiseptic property is good, is convenient to processing, low cost of manufacture, the electric conductivity and the useful life of improving earthing device.Adopt earth electrode to be connected the connected mode of earth connection with erection joint through connecting line; to be welded in whole preservative treatment on the earth electrode than short connecting line earlier; be convenient to processing; and be connected firmly; contact-making surface is big; conduct electricity very well; again earth connection is locked through erection joint and the connecting line that is welded on the earth electrode in the work progress; easy construction; the job site need not welding, can not destroy the nano anti-corrosive layer and the zinc protective layer on earthing device surface, and it is underground that earthing device is connected to intactly; strengthen its anticorrosion, rustless property, prolonged earthing device useful life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, earth electrode 1, connecting line 2, erection joint 3, earth connection 4, zinc layer 5, combined anti-corrosion layer 6.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Shown in Figure 1, welding " L " shape connecting line 2 on earth electrode 1, " L " shape minor face of connecting line is welded on the earth electrode 1, solder side is big, firm welding conducts electricity very well, and the long limit of " L " shape of connecting line is perpendicular to earth electrode 1, connect earth connection 4 by erection joint 3 lockings, earth connection 4 can or be vertically connected at connecting line 2 through erection joint 3 levels.Add man-hour, sharp cone distal is processed in earth electrode 1 bottom, behind earth electrode 1, connecting line 2, erection joint 3, earth connection 4 difference galvanizing protective layers 5, on the zinc layer, carry out combined anti-corrosion layer 6 again and handle.
During construction, directly earth connection is connected with connecting line locking on being welded in earth electrode by erection joint and gets final product, the scene need not to weld, and does not destroy anticorrosive coat, easy construction, reduction construction intensity.
