SUBMERSIBLE ELECTROCHEMICAL GENERATOR Russian patent published in 1995 - IPC

FIELD: chemical sources of electric energy. SUBSTANCE: submersible electrochemical generator has case housing water-and-lithium source of energy in the form of cylindrical cathodes and lithium anodes pressed into sleeves and interconnected electrically. Anodes are provided with final control elements of hydraulic system of contact pressure "anode-cathode" based on bellows. Electrolyte circulation agitator is also incorporated in case. Case is manufactured from electro-and heat- insulating alkali-resistant material having density not less than 1.0 kg/cu.dm and is provided with separable cover and bottom. In upper part of case there are made closed inlet and outlet ducts with holes incoming and outgoing flows of electrolyte of sources of energy and slots of electrical connections of electrodes of sources of energy. Annular grooves open from below which house source of energy are made in body proper of case. Cathode of each source of energy is anchored immobile in upper part of case and anode is mounted for movement with reference to cathode and case as anode is consumed. Final control elements of hydraulic system of contact pressure "anode-cathode" are fabricated in the form of bellows and are anchored on bottom of case uniaxially to anodes. Bottom has duct intercommunicating bellows and hydraulic system of contact pressure "anode-cathode". EFFECT: simplified design, enhanced operational reliability. 3 cl, 4 dwg
