Abstract:
1. A bracelet anode assembly to provide enhanced cathodic protection to one or more vertical well casing sections in a cellar area, the cellar area being bounded by a cellar ring and being partially filled with a backfill containing an electrolytic composition surrounding the one or more vertical well casing sections, the one or more vertical well casing sections in the cellar area defining a cellar-area well casing, the bracelet anode assembly comprising: a plurality of arc-shaped bracelet anodes adapted to circumferentially surround a cylindrical subsection of an outer surface of the cellar-area well casing such that the plurality of arc-shaped bracelet anodes being operable to be mechanically connected in a substantially circular tightenable bracelet form that, when tightened, is operable to clamp the plurality of arc-shaped bracelet anodes to a fixed vertical position on the cylindrical subsection of the outer surface of the cellar-area well casing, each respective arc-shaped bracelet anode of the plurality of arc-shaped bracelet anodes comprising: a plurality of connectors to mechanically connect each of the plurality of arc-shaped bracelet anodes to the one or more adjacent arc-shaped bracelet anodes in the substantially circular tightenable bracelet form, each of the plurality of connectors adaptable to be connected to the bracket at one of the distal ends of the arc-shaped anode frame of the respective arc-shaped bracelet anode and further connected to the bracket of one of the distal ends of the arc-shaped anode frame of the one or more adjacent arc-shaped bracelet anodes, thereby allowing the substantially circular tightenable bracelet form to be operably tightened by force applied to the plurality of connectors; one or more metallic shorting rods, each of the one or more metallic shorting rods to be positioned through the anode orifice of a respective arc-shaped anode core for each of the plurality of arc-shaped bracelet anodes so that the respective metallic shorting rod is operable to contact the outer surface of the cellar-area well casing, each of the plurality of metallic shorting rods thereby being operable to be in direct electrical contact with the respective arc-shaped anode core such that each of the one or more metallic shorting rods is operable to complete an electrical connection between the respective arc-shaped anode core and the outer surface of the cellar-area well casing to provide an electron pathway between the respective arc-shaped anode core and the outer surface of the cellar-area well casing, the electron pathway and the ion pathway completing an enhanced galvanic anode cathodic protection circuit.
