Abstract:
A tidal gate system for a regulating the flow of tidal waters between a first side and a second side of a main opening, the tidal gate system comprising:a primary door member arranged for movement between open and closed positions relative to the main opening, where gravity biases the primary door member into its closed position, and the primary door member defines a regulated opening; a secondary door member arranged for movement between open and closed positions relative to the primary door assembly, where gravity biases the secondary door member into its closed position, and the secondary door member covers the regulated opening when in its closed position; a door float configured to cause the secondary door assembly to move out of its closed position when a primary water level on the first side of the main opening exceeds a predetermined regulated opening level; and a regulation float, where the regulation float is operatively connected to the secondary door assembly such that the regulation float forces the secondary door assembly into its closed position when the primary water level exceeds a predetermined regulation float level.
