Power drive system for converting natural potential energy into a driving power to drive a power generator

A power drive system for converting the potential energy of the rising and falling of the tide into a driving power to drive a power generator, comprising:

• a water collecting barrel vertically fastened to the oceanic crust under the sea level, having two sets of radial through holes circumferentially disposed under said sea level at two elevations on the barrel, and a reduced top end connected to a power input port of a power generator;
• a plurality of water tubes having first and second ends thereof, said first ends being respectively connected to said radial through holes for guiding sea water into said water collecting barrel to move said power input port of said power generator;
• a plurality of rockers, each rocker having a fixed end pivoted to said water collecting barrel between said two elevations and a free end, reciprocating between said second ends of the water tubes at said two elevations;
• a plurality of floating devices floating on the sea level;
• a plurality of connecting rods, disposed beneath the sea level, each having one end fixedly secured to one floating device and an opposite end pivoted to said free end of one rocker;
• and
• water pump means at said second ends of the water tubes distant from respective said radial through holes on the barrel and driven by said rockers to pump water into said water tubes and said water collecting barrel to force said power generator into operation.
