(54) | Hinge-assembly for the articulation of a pivoting sluice gates |
(57) A mobile barrier (1) for temporary barrage of canals and harbour entrances essentially
formed by a base (2) which extends on the bottom of the harbour entrance, and a series
of sluice gates (3) of essentially rectangular shape which are hinged with one edge
onto the base (2) one next to the other so as to swingingly turn about a main essentially
horizontal axis of rotation (A); each sluice gate (3) being connected to the base
(2) by means of a pair of disconnectable hinges (4) which consists in a fixed portion
(4a) stably anchored to the base (2), and a mobile portion (4b) which is instead stably
fixed to the sluice gate (3), incorporates the articulation joint of the hinge about
the main axis of rotation (A) and is finally structured so as to couple with the fixed
portion (4a) in a stable yet easily releasable manner.
