Abstract
The utility model provides an earth device without maintenance, comprising a metal pipe, wherein a wiring terminal is connected with the metal pipe; an electrolyte inner filling layer is filled in the metal pipe; an outer filling layer is arranged outside the metal pipe; two ends of the metal pipe are respectively provided with a plug. The device of the utility model is characterized in good earthing effect, small occupied area, long life-span and the capability of avoiding maintenance.
Description
The utility model relates to a kind of earthing device that is used for building, special installation.
In facilities such as some towering buildings, mobile communication base station, computer room, building automatic, require to be provided with earthing device.Traditional earthing device is to lay earth mat.This earth mat need take bigger area, and it is cumbersome to construct, and is subjected to the influence of natural environment bigger, need often safeguard.Along with development of modern science and technology, more and more higher to the ground connection effect of requirement, traditional earth mat can not satisfy the needs of ground connection.Intensive along with urban population sought suitable place and done earth mat difficulty relatively in built-up modernized city.
The purpose of this utility model is to provide the non-maintaining earthing device that a kind of floor space is little, ground connection is effective.
The purpose of this utility model is achieved in that it comprises metal tube, is connected with binding post on the metal tube, is filled with packed layer in the electrolyte in the metal tube, packed layer outside metal tube is outside equipped with, and there is plug at the two ends of metal tube.
The utility model can also comprise: place suitable for reading is provided with head protector at metal tube.
Advantage of the present utility model is: compact conformation, and floor space is little, is particularly suitable in modernized metropolis as earthing device; Ground connection is effective, and metal tube wherein adopts good, the corrosion resistant metal material of conductive effect, is best with copper.The material of interior packed layer is some ionic compounds, after the moisture content of ionic absorption the earth, in the soil around can active ion being discharged into effectively by deliquescent effect, thus the soil property around having improved, make it to reach grounding requirement, can obtain good ground connection effect; Outer packed layer is to have anticorrosion, as to fall resistance, moistening effect material by some to constitute, and plays soil is carried out chemical treatment, reduces the resistivity of soil and the effect of protection metal tube.Device of the present utility model in a word has that ground connection is effective, and floor space is little, long service life, can be non-maintaining etc. advantage.
Accompanying drawing is a structural representation of the present utility model.
For example the utility model is done more detailed description below in conjunction with accompanying drawing: it comprises metal tube 1.Metal tube adopts copper pipe usually.Be connected with binding post 2 on the metal tube.Be filled with packed layer 3 in the electrolyte in the metal tube.Packed layer 4 outside metal tube is outside equipped with, and outer packed layer is made up of the sodium metasilicate gel.Place suitable for reading is provided with head protector 5 at metal tube.Upper and lower mouthful of place is provided with plug 6.
Claims (2)
1, a kind of non-maintaining earthing device, it is characterized in that: it comprises metal tube, is connected with binding post on the metal tube, is filled with packed layer in the electrolyte in the metal tube, packed layer outside metal tube is outside equipped with, there is plug at the two ends of metal tube.
2, non-maintaining earthing device according to claim 1, it is characterized in that: place suitable for reading is provided with head protector at metal tube.
