The middle axis part of the cylinder conductor is provided with the metal rod penetrating the cylinder conductor. The surface of the cylinder conductor is provided with an exchange hole. A water supplementing unit and a feeding unit are arranged above the exchange hole. The active resistance-reducing materials are composed of a modified soil matrix material and a water-soluble polymer cellulose sustained release agent. Compared with a conventional earth electrode, the above earth electrode has the advantages of simple usage, good electrical conductivity, long continuous working period and no environmental pollution.
Description
Technical field
The utility model relates to a kind of earthing device, particularly a kind of earth electrode that contains active resistance-lowering material.
Background technology
Earth electrode is a kind of conductor of placing into the soil and being connected with the earth, is a kind of common earthing device of engineering lightning protection that is applied to.Existing earth electrode is generally a metallic conductor simple in structure, and appearance is a copper alloy, and inside is made up of ceramal compound and special electrolytic ion compound; Cause following defective: the one, this earth electrode surface area is limited; The current flowing face is little, if surrounding soil resistivity is high, also needs in soil, to dose in advance backfill or the resistance reducing agent with dilatancy, water absorption and ion permeability; Strengthen ion-exchange performance; To improve the current flowing face, improve the surrounding soil electric conductivity, reduce surrounding soil resistivity; The 2nd, this earth electrode is easily by the acidic materials material corrosion in the soil, and the metal oxide that produces after the earth electrode corrosion covers earth electrode metallic conductor surface, causes the earth electrode electrical efficiency to reduce; The 3rd, this earth electrode will add the electrolytic ion compound; Discharge active electrolytic ion; In order fundamentally to alleviate the etching problem of earth electrode; Also will add alkali weak acid gelling thing, and in soil, dose backfill in advance or mostly resistance reducing agent is chemical substance, heavy metal ion can pollute soil, groundwater resources and peripheral biological environment in earth electrode and the resistance reducing agent; The 4th, this buried earth electrode be owing to can't obtain moisture and replenish, can not and soil between produce Water Cycle and exchange, influence the earth electrode ion-exchange performance, greatly influenced the earth electrode conductive capability.
Summary of the invention
To existing earth electrode directly adopt the metallic conductor surface area limited, be prone to cause corrosion cause electrical efficiency reduce, to problems such as environment produce a little less than pollution, moisture and the ion-exchange performance, a kind of novel grounded utmost point is proposed.
A kind of earth electrode of the utility model; It is characterized in that this earth electrode by cylindrical conductor, metal bar, active resistance-lowering material are formed, and cylindrical conductor is the hollow circular cylinder that electric conducting material is processed; The active resistance-lowering material of inner filling, shaft position is provided with a metal bar that runs through cylindrical conductor in the cylindrical conductor.
Foregoing a kind of earth electrode is characterized in that the cylindrical conductor surface is provided with exchange hole, and the top is provided with water replanishing device and feed supplement device, and water replanishing device comprises filter screen and moisturizing conduit, and the feed supplement device comprises cover plate and feed supplement conduit.
A kind of earth electrode of the utility model, because the existing earth electrode surface area of its cylindrical conductor profile is big, corresponding electric current circulating face is big, electric conductivity is superior to existing earth electrode.Active resistance-lowering material can carry out material and exchange of moisture through exchange hole and soil, on the one hand, continues to keep the total quantity of conductive ion in the earth electrode cylindrical conductor and the moisture of active resistance-lowering material, keeps the electric conductivity of earth electrode; On the other hand,, reduce surrounding soil resistivity, improved the electrical efficiency of earth electrode through ion-exchange.In addition, active resistance-lowering material reaches country's " soil environment quality standard (GB15618-1995) " index, have characteristics such as long-acting, environmental friendliness, and antiseptic property is good, metal bar is had the effect of anti-corrosion.Water replanishing device receives the moisture of natural precipitation, replenishes and increase interior active resistance-lowering material moisture content, and the feed supplement device can replenish active resistance-lowering material at any time, keeps earth electrode performance and electrical efficiency.
