Modularized high-pressure gas storage device

The utility model relates to a modular high-pressure gas storage device. The device is formed by combining a plurality of gas storage modules, wherein the gas storage modules are connected in series or in parallel through high-pressure pipelines and high-pressure connectors, each gas storage module comprises a frame, a plurality of gas cylinders arranged in the frame and pipelines used for connecting the gas cylinders, and each gas cylinder comprises an aluminum inner container and a carbon fiber winding layer wound outside the aluminum inner container. Installation is convenient, a foundationdoes not need to be manufactured specially, the modules are connected through high-pressure pipelines and high-pressure connectors, and the modules can be connected in series or in parallel. The gasstorage bottle made of the carbon fiber composite material is of an aluminum inner container and carbon fiber multi-layer winding structure and has the advantages of being light in weight, large in gas storage capacity, high i
