I could be wrong but I think it is something the bomb squad uses.

As mentioned, bomb squad equipment. I think the technical term is 'bomb containment chamber'. They put the suspected bomb in it so it can be moved safely out of the area to be dealt with.

This looks different but same idea:

Now I have look up weather machines! LOL
