ANODE EARTHING DEVICE AND METHOD OF ITS INSTALLATION Russian patent published in 2010 - IPC C23F13/06 H01R4/66 

FIELD: electricity.

SUBSTANCE: invention refers to electrochemical protection of underground structures against corrosion and can be used during construction of anode and working DC earthings. Anode earthing device differs by the fact that the electrode arranged in lower part is equipped with additional current lead with additional current-conducting wire; connections of electrodes are tightly enveloped with flexible cup made from dielectric material. Upper and lower electrodes are equipped from above and from below respectively with flexible caps made from dielectric material with holes for the main and additional current-conducting wires; lower electrode is equipped with process branch pipe equipped with a guide for the lowering device of the lifting mechanism. Invention also refers to installation method of anode earthing device including the bottom-up assembly of electrodes one above the other to the electrode with current-conducting wire, lowering to vertical well (bore hole) by means of the lowering device (rope, wire rope, cable) of the lifting mechanism with further filling of the bore hole with anode earthing in the central part with electroconductive substance, and from above - with coarse-porous loose material.

EFFECT: invention allows simple assembling and arranging from the surface in the bore hole during installation of anode earthing device by minimising the possibility of electrode contacts fouling, and ensuring the monitoring of anode earthing device condition.
