Abstract
The utility model relates to an grounding device, comprising a grounding conductor integrated by two semicircular cylinder-shaped conductors, a connecting board respectively connected at the two semicircular cylinder-shaped steel conductors, an upper cover fitting with the upper end of the grounding conductor and provided with a water inlet hole, a plurality of small holes arranged at the periphery of the upper part of the grounding conductor, an inner cavity divided into the upper natural water filling area and the lower water absorption material filling area. The grounding conductor and connecting board are both made of steel materials. The conductor has a large diffusing surface area and a reliable conduction dual circuit, in addition, the conductor can constantly keep moistening without maintenance, making the least grounding resistance quantity. The utility model can be used for the grounding projects of electric power, communication, computer, construction, and other relevant industries.
Description
Technical field
The utility model relates to a kind of safety device, particularly relates to a kind of earthing device.
Background technology
The earthing device that tradition is used is band steel, round steel, angle steel and steel pipe etc.Chinese patent 93239478.7 discloses a kind of earthing device, comprises a container, vessel top have with container in the empty metal tube that connects, container bottom have with container in the empty micropore metal pipe that connects, earthing conductor is connected in metal tube.This device is difficult to satisfy the requirement of modern earth work to earth resistance or installation field boundary ground, particularly in area dry or that soil resistivity is higher, the effective land area that perhaps is used to install earthing device hour must adopt and bore deep-well, soil blasting, throwing and execute modes such as resistance reducing agent or perfusion saline solution and solve problem.And adopt not only engineering cost height of these modes result, constructional difficulties, but also can cause destruction to soil or biological environment.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of reliable conduction double loop that has is provided, and can keep moistening for a long time under non-maintaining condition, thereby make the minimum earthing device of grounding resistance.
The utility model earthing device comprises the earthing conductor that is formed by connecting by two semi-cylindrical shaped conductors, be connected to the connecting plate on the two halves cylindrical steel conductor, with the loam cake that cooperates and have the inlet opening on the earthing conductor, there are aperture, its inner chamber to be divided into top natural water fill area and bottom absorbent material fill area around the earthing conductor bottom.Wherein, two semi-cylindrical shaped conductors can connect by flange.Earthing conductor and connecting plate adopt steel plating zinc on surface material, have not only strengthened the conduction of conductive surface and the diffusing fluidity energy of earth current, and grounding resistance is further reduced, and anticorrosive, long service life.Connecting plate is used for being connected with main ground network, and forms the most reliable conduction double loop.Aperture around the inlet opening of earthing conductor loam cake and the bottom be convenient to moisture in the soil infiltrate in the earthing conductor or the moisture in the earthing conductor inner chamber to its surrounding wetting, to keep earthing conductor and surrounding environment moistening, reduce earth resistance.The absorbent material of earthing conductor inner chamber is used to keep moisture.
The operation principle of the utility model earthing device is, during use, dig a cylindrical melt pit on ground, fill special clay in the melt pit bottom, and compacting, make the specific soil conductivity of special clay be not more than 100 Europe rice, then earthing conductor is put into melt pit, and around earthing conductor, fill special clay, and compacting, in earthing conductor, fill absorbent material, as water-absorbing sponge etc., fill water then, cover loam cake, and fill special clay on earthing conductor top, compacting, connecting plate is connected with main ground network, can realizes main ground network ground connection, with assurance equipment and components and parts ground connection.
The advantage of the utility model earthing device is that the diffusing stream of conductor surface area is big, and has reliable conduction double loop, can keep moistening for a long time under non-maintaining condition, thereby make grounding resistance minimum.The earth work that is used for electric power, communication, computer, building and other relevant industries.
