Detailed Description of the Invention

[0001]

The present invention relates, carried an empty gas cylinder, and store after filling the gas, filling of high pressure gas to be carried out at any time, relates to methods and constructs for such storage, further more
Properly relates to those aimed at the safety during storage.

[0002]

2. Description of the Related Art Gas cylinders such as empty LP gas are
The gas is collected in a high-pressure gas filling station, filled with gas, temporarily stored, and then shipped at any time. In the conventional high-pressure gas filling station, a gas cylinder loading section, a gas filling section, a gas cylinder storage section, and a gas cylinder unloading section are provided on the same floor, so to speak, and a flow-based management method is adopted. .

[0003]

However, the above-mentioned conventional high-pressure gas filling station has the following problems. That is, when handling high-pressure gas, it is legally impossible to provide a floor above the storage. Therefore, the high-pressure gas filling station has a flat structure in which each process is arranged on the same floor. In order for the high-pressure gas filling station to secure sufficient processing capacity, sufficient storage capacity for the gas cylinder is required, but the conventional structure requires a large site for the above reasons. However, it is difficult to secure a large land in an urban area that is close to a densely populated area and convenient for the location of high-pressure gas filling stations.
This makes it virtually difficult to construct high-pressure gas filling stations with sufficient processing capacity in urban areas.

Therefore, an object of the present invention is to provide an empty gas cylinder in a city area where it is difficult to secure a large land, store it after filling it with gas, and carry it out at any time. By making effective use of the land by adopting the above, it is possible to construct a structure for filling and storing high pressure gas having a sufficient processing capacity, that is, a high pressure gas filling station. Also,
Another object of the present invention is to efficiently carry in, store and carry out a large amount of gas cylinders, and sufficiently consider safety during storage .
