[0024] As Figs. 1-5 The utility model uses the principle as follows:

[0025] First, the fixed base 1 is placed on the cargo platform of the hydrogen energy logistics vehicle, then the rotating lead screw 23 is rotated, the sliding seat 21 slides outwards in the guide chute 12 to adapt to the size of the hydrogen storage tank, after adjustment, the hydrogen storage tank is placed on the bearing table 11, the rotating lead screw 23 is reversed to move the arc-shaped fixed plate 22 inwards until it is in close contact with the outside of the hydrogen storage tank, thereby realizing mechanical fixation of the hydrogen storage tank. Finally, the connecting rod 32 is rotated to unfold the protective tarpaulin 34 in the storage box 33 and cover it on the upper end of the hydrogen storage tank, and the protective tarpaulin 34 is used to protect the hydrogen storage tank to avoid direct sunlight on the hydrogen storage tank during transfer, thereby preventing the hydrogen storage tank from overheating due to long-term exposure to sunlight, ensuring the safety and stability of the hydrogen storage tank.
