ABSTRACT:
In a preferred embodiment, a clamping structure is mounted around a drilling-bit tube and is structured for permitting the clamping structure to rotate in counter-clockwise direction slidably around the drilling-bit tube and to permit the clamping structure to slide upwardly on the drilling-bit tube but to bring about a clamping and gripping of the drilling-bit tube whenever the clamping structure has clock-wise and/or downward force imparted thereto relative to a stationary state of the drilling-bit tube such that clockwise and/or downward force on the clamping structure serves to rotate the drilling tube in a clockwise direction and/or to press and move downwardly the drilling-bit tube, and intimate with the clamping structure there being an outer-cylindrical-surface structure having helical female grooves extending angularly downwardly in each of clockwise and counter-clockwise directions, and there being a circumscribing cylindrical tubular structure having radially-inwardly extending finger-projections shaped for having their respective distal inner ends ride slidably mateably within the helical female grooves such that upward and downward alternate movements of the cylindrical tubular structure imparts rotary motion to the outer-cylindrical-surface structure, and mounted intimately to and around the cylindrical tubular structure there being a spherically-shaped float having a large mass and defining in a substantially horizontal plane and extending around the periphery of the spherical shape thereof consecutive serially arranged uprightly-extending turbine-blade structures positioned and shaped such that water-current force on the turbine-blade structures imparts a clockwise motion to the float.
