Patent ID: 8661807

Claim:
A potential energy regenerating system, comprising: a seesaw module, comprising a rectangular smooth plate, a center of which is placed on a base, so that both ends of the smooth plate are capable of swinging up and down, a partition device being provided on the center of the smooth plate for partitioning the smooth plate into two sides, each side of the smooth plate being provided with a baffle plate perpendicular to the smooth plate for stopping a mass sliding down along the smooth plate, the baffle plate having an opening through which a pipe line passes; two liquid storage bag modules, each comprising a compressible liquid storage bag, placed on both sides of the plate of the seesaw module, respectively, a bottom of each compressible liquid storage bag having an access opening and fixed on a flat plate; a liquid storage tank module, comprising a liquid storage tank with a bottom higher than that of a liquid access opening switch control device, the liquid storage tank having an inlet and having two outlets at a bottom of the liquid storage tank, the two outlets being connected to the liquid input pipe lines of the liquid storage bags on the right and left sides, respectively, each of the outlets being provided with a plug connected to a control rope, for controlling the outlets to be open or closed, the control rope connected to the liquid input pipe line of the right compressible liquid storage bag being connected to the left squeezing weight mass of the seesaw module, the control rope connected to the liquid input pipe line of the left compressible liquid storage bag being connected to the right squeezing weight mass of the seesaw module, the plug having an appropriate weight, wherein when the control rope is released, a corresponding plug falls down to close a corresponding outlet, and when the control rope is pulled, the corresponding outlet is opened; and the liquid access opening switch control device, one end of which is connected to the access opening of the compressible liquid storage bag, the other end of which has two pipe line openings, wherein one opening is connected to the inlet of the liquid storage tank, and the other opening is connected to a corresponding outlet of the liquid storage tank, the liquid access opening switch control device allowing liquid to flow in one way.
