Abstract
The utility model relates to a system for storing high pressure gas under the sea. According to the system, the gas is continuously compressed into a closed gas tank arranged under the sea through an air inlet pipe by utilizing a gas compressor; when the high pressure gas in the closed gas tank is required, the closed gas tank releases high pressure gas to an external energy conversion device through an exhaust pipe; internal and external sensors transmit pressure values a controller to carry out pressure comparison so as to control a lifting device; when the high pressure gas is filled into the closed gas tank, the lifting device drives the closed gas tank to sink, when the high pressure gas is externally released from the closed gas tank, the lifting device drives the closed gas tank to float up, and the difference of the internal pressure and the external pressure borne by a shell of the closed gas tank is in a pressure bearing range of the shell when the high pressure gas is stored in the closed gas tank or is released from the closed gas tank, i.e., more high pressure gas can be filled into the closed gas tank and does not need to be supported by a thicker tank wall, so that the manufacture cost of the closed gas tank is relatively low.
