Self-winding power generating systems and methods for downhole environments

A self-winding power generating device for monitoring well conditions, the device comprising:

• a mechanical winding knob for receiving mechanical energy from a downhole environment;
• a gear train comprising a plurality of gears engaged with each other, wherein a first gear in the gear train is operatively connected to the mechanical winding knob, and configured to receive mechanical energy from the mechanical winding knob and transfer the mechanical energy to a second gear in the gear train;
• a spiral spring attached to one of the gears in the gear train, the spiral spring configured to self-wind and store the mechanical energy upon receiving the mechanical energy from the first gear;
• an oscillating rotor weight configured to automatically rewind the spiral spring harnessing the mechanical energies in the downhole environment, wherein the mechanical energy in the downhole environment is caused due to drillstring rotation when tripping in or out of the wellbore, when stationary and drilling a formation, or due to turbulent drilling fluid flow, and the rotor weight rotations are translated to the spring through reverser or reducer gears;
• a power generation unit configured to receive the mechanical energy from a last of the plurality of gears and convert the mechanical energy into electrical energy;
• and
• a bridge rectifier operatively connected to the power generation unit, the bridge rectifier configured to convert AC, received from the power generation unit, to DC, where
• the self-winding generation device is configured to be dropped down a well and travel with a drilling fluid flow down the well, out of a bit, then back up an annulus and casing all the way to the surface, where data from the self-winding power generation device is transferred to a computer on a drilling surface.
