Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cells, in particular to a solid-state hydrogen storage module transportation and storage system. Background Art

[0002] Solid-state hydrogen storage technology boasts advantages over gas cylinder hydrogen storage, including higher storage capacity, the absence of high-pressure or insulated containers, improved safety, and no explosion hazard. Consequently, it is gaining a growing market share in hydrogen fuel cell forklifts. However, due to the relatively high weight of solid-state hydrogen storage, in some applications where direct refueling of the solid-state hydrogen storage module is not possible, the replacement of solid-state hydrogen storage modules presents a significant constraint on the development of solid-state hydrogen forklifts.

[0003] At present, the main method of hydrogen supply is to use hydrogen fuel cell forklifts with solid-state hydrogen storage. When replacing the solid-state hydrogen storage module, a small forklift fork is mainly used to extend into the forklift body and slowly drag the solid-state hydrogen storage module out. Although this method can replace the solid-state hydrogen storage module, it requires the cooperation of multiple people to complete, and it takes a long time. If the operation is improper, it will cause the solid-state hydrogen storage module to fall, posing a certain safety risk to the operator. Moreover, the current storage solution for solid-state hydrogen storage modules is mostly to weld a cube frame with profiles and place the solid-state hydrogen storage module on it. This storage method occupies a relatively large area, and both lifting and placement require another forklift using a lifting belt, which is very inconvenient.

[0004] In view of this, the present invention provides a solid-state hydrogen storage module transportation and storage system to solve the above problems. Utility Model Content

It is also easy to install and disassemble, allowing users to flexibly assemble and adjust according to actual needs, thereby improving the practicality and convenience of the entire device.

[0073] The base mounting plate 22 is fixedly connected to the base 23 . A through hole is provided on the base mounting plate 22 , and the base mounting plate 22 is fixed to the ground with anchor bolts through the through hole, thereby fixing and supporting the storage device 2 .
