Beschreibung
Zusammenfassung:	A water bag for energy storage comprises a flexible bag body, a folding mechanism and a connecting pipe, and is characterized in that a metal upper pressing plate (8) is arranged at the top end of the flexible bag body, a metal lower pressing plate (9) is arranged at the bottom end of the flexible bag body, and the folding mechanism comprises a first folding outer side mechanism and a second folding outer side mechanism. The first folding outer side mechanism is provided with two rubber large outer rings (1) which are adjacent to the metal upper pressing plate (8) and the metal lower pressing plate (9) respectively, the connecting pipe (7) is arranged in the middle of the metal lower pressing plate (9), and a connector of the connecting pipe (7) is used for connecting the bag body with an external water pipe. The water bag type gravity energy storage device has the advantages that the most difficult sealing ring problem of a piston type gravity energy storage scheme is solved, the water bag is used for replac
