Constant-pressure compressed air energy storage system depending on natural conditions

The utility model belongs to the technical field of energy storage, aims to solve the problems of high construction difficulty, poor reliability and high cost of the conventional compressed air energy storage scheme, and particularly relates to an equal-pressure compressed air energy storage system depending on natural conditions, which consists of an upper water storage reservoir, a lower air storage chamber and a power station, based on natural fall or existing conditions, static pressure is generated by water columns corresponding to the fall of the water storage reservoir and the air storage chamber to maintain the pressure intensity of compressed air. Wherein the natural fall comprises a height fall formed by mountain terrain or a height fall between a sea surface and a seabed; the method depends on existing conditions such as a pumped storage power station upper reservoir, a waste mine, a natural tunnel, a waste artificial fortification, a scrapped ship or other waterproof sealed cavities. The constant
