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). |
