    Abstract: A system for storing energy includes a body and a shaft having walls defining an internal volume for containing a fluid, a seal member disposed between the body and the walls of the shaft, and a fluid passage in fluid communication with the shaft. The body is disposed within the internal volume of the shaft for movement with gravity from a first elevation position to a second elevation position within the internal volume of the shaft. The seal member divides the internal volume into a first portion located below the body and a second portion located above the body. The fluid passage communicates fluid with the first portion of the interior volume of the shaft. The system further includes a pump/turbine operatively coupled with the fluid passage to drive a motor/generator to generate electricity upon movement of the body from the first elevation position to the second elevation position.

    Abstract: A liquid seal energy-accumulator and hydraulic system thereof based on liquid-collector and sandwich piston is provided. The liquid seal energy-accumulator includes a piston cylinder (HSG) and a high pressure gas-tank (QTG). When a piston (HS) moves to a top of the piston cylinder, the leaked pressure liquid accumulated on the top of the piston flows into the gas-tank through a gas-liquid channel (TD), so as to timely clean up the pressure liquid accumulated on the top of the piston. The pressure liquid collected at the bottom of the gas-tank is increased for upwardly moving a buoy (FT), when the buoy presses a collected-liquid sensor (JYG), a signal is sent for opening an electronically-controlled-valve (DKF), the leaked pressure liquid flows from the liquid leakage pipe (LYG) back to the liquid-container (SYT).
