    摘要： A protection device (100), comprising:
    - a plurality of metal lamellae (1), each having a first front wall (2A) and a second rear wall (2B), arranged as a sequence and overlapped with each other so that the first front walls (2A) define, as a whole, a continuous closing surface (3), said lamellae (1) being relatively movable along a first moving direction (D1) in order to modify in at least an area of the continuous closing surface (3) the overlapping degree between at least a portion of said metal lamellae (1),
    - a plurality of dragging modules (4), arranged at the second rear wall (2B) of the lamellae (1) in different operative regions (R1, R2, R3) with respect to a second direction (D2) orthogonal to the first direction (D1) so to occupy only partially the rear area corresponding to the closing surface (3), each dragging module (4) comprising:
    - a bellows piece (5);
    - a plurality of supporting frames (6);
    - an extension limiting strap (7);
    and wherein
    - each supporting frame (6) is fastened to the second wall (2B) of a metal lamella (1) at a coupling area;
    - said bellows piece (5) is interposed and blocked between each supporting frame (6) and the respective metal lamella (1) so to define ridges (C) and valleys (V) between each supporting frame (6) and the next one.

    摘要： The present invention includes a plurality of protective bodies (13, 14, 15) sequentially connected in a moving direction of a moving body and separating a movement path of the moving body from the outside. The protective body (15) at a first end is connected to a predetermined end (12a) of an area to be protected, and the protective body (13) at a second end is connected to the moving body. The plurality of protective bodies (13, 14, 15) are configured to be expanded and contracted as a whole by movement of the moving body. A structural body (35) having a groove (35a) having a top opening and forming a flow path is provided. The structural body (35) is arranged along the protective bodies (13, 14, 15) below the protective bodies (13, 14, 15) or arranged along the protective bodies (13, 14, 15) such that the lower ends of the protective bodies (13, 14, 15) are inserted in the groove (35a) through the top opening of the groove (35a). The groove body (35) is provided with a nozzle (38) ejecting a liquid into the groove (35a), and a pressurized liquid is supplied to the nozzle (38) from a liquid supply source (40).
