Abstract (en)

[origin: US6196764B1] An automatic flashboard (10) comprises a wall (12) installed on a hydraulic structure (11) so as to be capable of passing from an erect position in which it retains a mass of water to a lowered position in which it allows the water to pass substantially without obstruction, and at least one elongate retaining member (13) for holding the wall (12) in its erect position against horizontal thrust (P1) from the mass of water (25). The retaining element (13) extends between the wall (12) and a reaction point to which it is connected by a connection (15) that can be automatically eliminated when the water reaches a certain level. The flashboard (10) also includes a massive element (16) movably mounted on the structure (11) and coupled to the mass of water so as to be in a stable state so long as the water remains below a predetermined level (N) and to pass into an unstable state and to be moved when the water reaches the predetermined level (N), the connection (15) being eliminated by the massive element moving.
