▎ 摘　　要

NOVELTY - The device has a base (1) whose upper end is formed with a mounting groove (3). Four front end corners of the base are formed with an L-shaped groove. An upper end of the base is fixedly connected with a protective mechanism. A storage tank (6) is fixed with an upper end of the mounting groove. A right upper side end of the storage tank is fixedly connected with an air inlet pipe. An outer side of the air inlet pipe is fixedly connected with a first valve. A left side of an exhaust pipe is fixedly connected with a second valve. A left side of the second valve is fixedly connected with an extending pipe. USE - High-pressure hydrogen storage device for a hydrogen-water graphene battery generating system. ADVANTAGE - The device moves a vertical rod along the L-shaped groove and external force direction when the device satisfies the external force, utilizes the spring to buffer so as to protect the internal storage tank and prevents the collision directly contact tank caused by the storage tank deformation, damage and explosion danger. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of a high-pressure hydrogen storage device. Base (1) Balance weight plate (2) Mounting groove (3) Vertical rod (5) Storage tank (6)
