A storage tank is provided inside the sealed box. The top end of the sealed box is connected with a sealed cover by a hinge. A vacuum insulation cavity is provided inside the side wall surface of the sealed box. A partition is fixedly installed inside the storage tank. A plurality of lead screws are evenly installed on the bottom wall surface of the sealed box. One end of the lead screw passes through the wall surface of the sealed box and is connected with a handle. A pair of movable blocks are movably installed on the lead screw. A connecting rod is hinged on the movable block. The other end of the connecting rod is hinged with a bearing platform. A tray is fixedly installed on the top end of the bearing platform.

[0006] Preferably, the partition is provided with a gas cylinder limiting hole above the position of the tray.

[0007] Preferably, a sealing strip is installed between the sealed cover and the sealed box.

[0008] Preferably, a self-locking ratchet is installed between the handle and the sealed box.

[0009] Advantageous Effects

[0010] The utility model provides a sealed hydrogen energy storage device, which has the following advantageous effects: When the device is in use, the lead screw and the movable block are used to drive the tray to rise and fall. When taking out the hydrogen cylinder, turn the lead screw with the handle and the tray will rise, pushing the hydrogen cylinder outwards, which is convenient for taking out the hydrogen cylinder and convenient to use.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1 - 3 , the present utility model provides a technical solution for a sealed hydrogen energy storage device: a sealed hydrogen energy storage device, including a sealed box 1, a storage tank 4 is provided in the sealed box 1, a sealing cover 3 is connected to the top end of the sealed box 1 by a hinge, a vacuum insulation cavity 2 is provided in the side wall surface of the sealed box 1, a partition board 5 is fixedly installed in the storage tank 4, a plurality of lead screws 8 are uniformly installed on the bottom wall surface of the sealed box 1, one end of the lead screw 8 passes through the wall surface of the sealed box 1 and is connected to a handle 11, a pair of movable blocks 7 are movably installed on the lead screw 8, a connecting rod 10 is hinged on the movable block 7, the other end of the connecting rod 10 is hinged to a bearing platform 9, and a tray 6 is fixedly installed on the top end of the bearing platform 9.
