Abstract
The present invention relates to a rapid-installation grounding electrode which comprises a ground inserting head, a grounding rod and a connector lug provided with a link structure of a grounding lead, wherein one end of the grounding rod is in threaded connection with the ground inserting head, the other end of the grounding rod is in threaded connection with the connector lug, and the number of the grounding rod can be one, or two, or more than two according to requirement. If the number of the grounding rod is two or more than two, each two grounding rod are assembled by a screw connecting pipe into a whole. The grounding electrode has the advantage that when the grounding electrode is installed, the ground surface does not need to be dug, and thus, the grounding electrode is particularly suitable for the equipment and the system which need grounding without breaking ground to make a ground network in cities or indoor rooms. In addition, because each two constructional elements are in screw connected, the grounding lead is connected with the connector lug without welding, and thus, assemble and installation do not need to use electric welding or oxygen welding, and the present invention is very suitable for combustible and explosive areas, and areas of no spark.
Description
One, technical field
The invention belongs to earth electrode, the earth electrode of device such as particularly a kind of alternate current operation ground connection, DC operation ground connection, safeguard protection ground connection, anti-static grounding, lightning protection.
Two, background technology
At present, earth electrode among the standard GB 50057-1994 " Code for design of lightning protection of buildings " is welded at the construction field (site) by common Zinc-coated angle steel, round steel or steel pipe, need excavate the zanjon of 0.5-0.8 rice during installation on ground, also must dig below the frozen soil layer at permafrost region, thereby not only workload is big during installation, and certainly lead to spark, can not use in the place on the inflammable and explosive place and the excavation ground of can not breaking ground.
Sold a kind of IEA electrolytic ion grounding system on the domestic and international market, earth electrode in this system mainly is coated with the tubular body of copper alloy by outer surface and the electrolytic ion compound that is loaded in the tubular body is formed, its advantage is to reduce the resistivity of surrounding soil, but weak point is can not use in the place on the excavation ground of can not breaking ground, because the installation procedure of introducing by its specification, every IEA earth electrode is installed in the upright opening that diameter is 30cm, must not directly squeeze in the soil, the IEA earth electrode of L type is installed in the dark groove of 1.5m.
Application number is that 98114445.4 Chinese patent application discloses a kind of distribution earthing device and uses vertical grounding electrode, this kind earth electrode mainly by the conduit of pane hammer, the electrode stem that is connected with the pane hammer tight fit, suit electrode stem, pour into conduit chemical pharmacon for reduced resistance, be positioned at the conduit upper end and form with the correcting locking cap that electrode stem is nested, the correcting locking cap is assembled into one by welding and conduit and electrode stem, and ground lead is welded on the correcting locking cap; If electrode stem is more than two or two, then be assembled into one by joint, the connected mode of electrode stem and joint is for pegging graft.This kind vertical grounding electrode at first need excavate the conical hole of a degree of depth 800mm when mounted, the connected mode of correcting locking cap and conduit, electrode stem, ground lead is welding, thereby still can not use in the place on the inflammable and explosive place and the excavation ground of can not breaking ground.In addition, also have following shortcoming: the reliability that (1) is electrically connected is relatively poor; (2) can only disposablely use; (3) the construction working amount is big, expends man-hour.
Three, summary of the invention
The present invention is directed to the deficiency that prior art exists, a kind of quick installing grounding pole that can use in the place on the inflammable and explosive place and the excavation ground of can not breaking ground is provided.
Technical scheme of the present invention is: the member of composition earth electrode includes the edge of a field, earth rod and is provided with the connector lug of ground lead syndeton, one end of earth rod with go into the edge of a field and be threaded, the other end is threaded with connector lug, the quantity of earth rod is decided as required, it can be one, also can be more than two or two,, be assembled into one by screw nipple between each earth rod if more than two or two.The main body of connector lug is a cylinder, and the one end has the screw that is connected with earth rod, and the other end is provided with a plate body, and the ground lead syndeton is through hole or the pin on this plate body, so that adopt non-welding manner to connect ground lead.Angle from protecting connector lug, prolonging its useful life also is provided with protective cover.Going into the edge of a field is made by high-carbon steel, earth rod and screw nipple are made by medium carbon steel, connector lug is made by mild steel, the surfaces externally and internally of above-mentioned each member all is coated with copper plate, if desired, also can on the copper plate of going into the edge of a field, earth rod, screw nipple, connector lug, cover chromium coating or nickel coating.
Earth electrode provided by the invention can be driven underground with portable electric hammer brill and artificial two kinds of methods, and the ground connection degree of depth can freely be selected.If meet cement, ceramic tile or granite ground, can be earlier with electric hammer drill at surface drilling behind soil layer, squeeze into earth electrode again.
The present invention has following beneficial effect:
1, structure of the present invention and mounting means show, its biggest advantage is not need to excavate ground when installing, thereby are specially adapted to the city or indoor can't breaking ground done earth mat and equipment and system that must ground connection.
2, owing to adopts and be threaded between each member, ground lead is not connected with connector lug and need welds, thereby assembles and motionless with electric welding or oxygen welding during installation, is highly suitable for inflammable and explosive place, the place use of spark can not be arranged.
3, because to form member few, easy to connect between each member, thereby install fast, compare with the earthing device of common earth mat, effect is installed improves more than 5 times.
4, be threaded owing to adopting between each member, thereby electric contact is reliable, coats conductive paste between screw thread, bolt, electric property is better.
5, because its design feature, can use in the place of temporary needs ground connection, finish using and can take out the next time of usefulness again, belong to and repeatedly use product.
6, the chromium plating because the member surfaces externally and internally is coated with copper plate, nickel coating, thereby have good anti-corrosive properties, can reach more than 20 years useful life.
7, owing to its design feature, each member all has interchangeability.
