HYDRAULIC UNIT OF BOREHOLE HYDRAULIC POWER PLANT Russian patent published in 2008 - IPC F03B13/06 F03B13/10 

FIELD: electricity.

SUBSTANCE: hydraulic unit of borehole hydraulic power plant includes hydraulic turbine that is connected to electric generator, which are installed in borehole, electric cable that connects electric generator on the surface with electric converter. Hydraulic turbine is turbodrill, electric generator is electric drill, which are unitised and connected by means of common casing with slots. To bottom part of casing fixing unit is connected, which includes bottom-hole thrust block, fixing unit levers and thrust levers, the sliding elements of which are installed with the possibility of movement along bottom-hole thrust block cone, thus affecting fixing element levers, causing their divergence to borehole walls. Hydraulic unit is equipped with unloading device, for instance, jack that is connected with top end of boring column.

EFFECT: operable device for power generation by borehole hydraulic power plant and avoidance of expenses for development of borehole hydraulic unit.
