Abstract (en)

[origin: WO9726412A1] An automatic wicket (10) including a wall (12) mounted on a hydraulic structure (11) and movable between a raised position in which it holds back a body of water and a lowered position in which the water flows substantially unhindered thereover, as well as at least one elongate retaining element (13) for holding the wall (12) in the raised position against the horizontal pressure (P1) from the body of water (25). The retaining element (13) extends from the wall (12) to a reaction point to which it is connected by a linkage (15) that may be inactivated automatically when the water reaches a predetermined level. The wicket (10) further includes a solid element (16) movably mounted on the structure (11) and coupled to the body of water so that it is stable while the water is below the predetermined level (N) but becomes unstable and is moved when the water reaches said predetermined level (N). The linkage (15) is inactivated by the movement of the solid element.
