摘要：

This is an apparatus for attaching a removable cover to a large vessel. It is adaptable to existing vessels, especially those which have a mounting rim or flange. It uses multiple connector pins which are attached permanently to the vessel and which can be fastened to the cover assembly by a remote operation. It also uses fluid pressure to force the cover against the vessel opening, after which the cover is mechanically secured in place by a second remote operation.
