SEALED DEVICE FOR DOCKING DIFFERENT DIAMETER MOVABLE ENCLOSURES

摘要

The invention relates to a sealed device (14) for docking movable enclosures (42) provided with different diameter caps (44) to a containment box (10). The inventive device comprises a central disc (22) and at least one docking flange (20a, 20b, 20c) which are concentric and normally close the access opening (18) of said containment box. A locking/unlocking unit (24) makes it possible to unlock the central disc (22) only or the central disc and one or several docking flanges (20a, 20b, 20c) according to the diameter of the cap (44). Said arrangement, in particular enables to clean the cap (44) of the mobile enclosure (42) used for transporting contaminated nuclear facilities.
