Abstract:
A buoyant flood guard barrier panel passively buoyantly rotationally pivotable upward from horizontal about a first horizontal axis overlays a subframe unattached to the panel. A secondary mechanism for raising the panel has one or more lift arms below the panel transverse to the first axis are rotationally mounted on a second horizontal axis parallel to, below and forward of the first axis. One or more powered drivers act on one or more driven member units each attached to a lift arm rearward of and lower than the second axis to pivot the lift arm on the second axis, rotating the arm upwardly under the panel to rotationally raise the panel. The powered driver may be a winch or a hydraulic actuator.
