ГЕНЕРАТОР ДЛЯ ПИТАНИЯ АВТОНОМНЫХ СКВАЖИННЫХ ПРИБОРОВ

摘要

FIELD: oil and gas well drilling, particularly to convert flushing liquid energy into electric one and to supply power to autonomous all-purpose downhole instruments. ^ SUBSTANCE: generator comprises stator, rotor made as body with magnets arranged from inner body side, as well as working turbine blades (augers) installed at rotor edges. Generator also has additional outer removable rotor body and turbines installed on intermediate removable bodies at rotor edges. End surfaces of additional removable outer body and end surfaces of working blades formed in turbines (augers) touching said end surfaces are beveled. Additional outer removable rotor body and working blades of turbines (augers) relatively intermediate bodies thereof are fixed by means of retention rings. ^ EFFECT: increased maintainability due to simplified generator component assemblage and disassembling. ^ 1 dwg
