Flood protection gate for vehicular & pedestrian traffic

Abstract

The invention relates to a roadway flood protection and traffic barrier which provides a smooth upper surface for vehicles, pedestrians, etc. and is thin enough to be mounted to the surface of an existing roadway or parking garage ramp, for example. A hinge mechanism is disclosed which facilitates the provision of a smooth roadway surface as well as a tight seal. A locking strut is provided that keeps the gate panels raised even in case of air pressure loss and which is remotely controllable.

Description

FIELD OF THE INVENTION[0001]This system relates to bottom hinged gates which may act as a barrier to water flow or may, alternatively or additionally be used as a barrier to vehicles. The gate in its lowered position provides may be configured to provide a smooth weight bearing continuation of the roadway surface or, alternatively, may be configured to mount on an existing roadway surface.PRIOR ART[0002]Conventional bottom hinged water control gates are fitted with irregularly shaped hinges and reinforcing ribs which do not obstruct water flow but do pose a hazard or even a barrier to vehicular or pedestrian traffic. Conventional bottom hinged traffic barriers have utilized mechanical hinges which are subject to leakage of water and corrosion and mechanical actuators which are subject to corrosion. Prior disclosures by this inventor have required deeper excavation depths and have not incorporated wedge connected air bladders and hinge flaps which provide superior economy and durabil...

AI Technical Summary

Benefits of technology

This patent describes a water control gate system that is easy to operate and safe for vehicle and pedestrian traffic. The system uses inflatable air bladders for pneumatic actuation, and the gate panels are constructed with minimal requirements for welds, which reduces costs and distortion. The hinge mechanism is strong and can handle shear loads, and a flexible barrier protects it from corrosive fluids and particles. The hinge also allows for smooth transmission of loads and accommodates misalignment and dynamic loads without damage. The system provides a smooth surface for water control without threatening recreational water uses or swimming facilities. The hinge retainer reduces friction and wear, and the system includes a compact enclosed hinge mechanism that eliminates sliding surfaces subject to contamination. Overall, this patent presents a technical solution for controlling water levels in a safe and effective way.

Problems solved by technology

Conventional bottom hinged water control gates are fitted with irregularly shaped hinges and reinforcing ribs which do not obstruct water flow but do pose a hazard or even a barrier to vehicular or pedestrian traffic.
