Benefits of technology

[0003]The present invention is comprised of one or more bottom hinged water barrier gates in conjunction with restraining means to prevent overturning of the gates in response to differential water pressure. The gate panels preferably incorporate controllable ballast chambers used to eliminate or minimize the actuating force required to raise the gates.

Problems solved by technology

But these require large and precise, and therefore expensive, foundations.
Radial gates, hydraulic flap gates, pelican gates, slide gates and roller gates all require intermediate piers which may be unacceptable in the case of a shipping channel, for example.
Heating of rubber seals in accordance with prior art is difficult.

Embodiment Construction

[0011]The accompanying drawings illustrate the general features of the gate in FIGS. 1 through 9. The gate panels 1 are preferably fitted with internal pipes 30 for emptying either water or air from the ballast chambers 31. Inflatable actuators 2, which may be filled with air or water, for example, may be used in conjunction with buoyancy effects to raise gate panels 1. Restraining means, such as restraining straps 3 may be used to prevent over-rotation of the gate panels and to resist hydrostatic loads resulting from water on the restraining strap 3 side of gate panels 1. Gate panels 1 are preferably sealed to each other with interpanel seal assembly 7 and sealed to the abutments with abutment seal assemblies 8. Clamps 25 may be used to secure inflatable actuators 2 and hinge flaps 22 to foundation 4. With gate panels 1 lowered, barges 31 my pass between abutments 5. Referring to FIG. 6, gate panel 1 is held up by inflatable actuator 2 and positioned at its pivot edge 32 by hinge f...

Abstract

A water control gate pivotable about a horizontal axis. Control may be by a combination of inflatable actuators and ballast chambers in combination with means for preventing over-rotation. Sealing between gate panels and between gate panels and abutments may be by means of seals inflated hydrostatically. The present invention is bottom hinged water control gate actuated by a combination of ballast chambers and inflatable actuators. The invention further includes an inflatable sealing means. The invention is particularly suited for use as a navigation lock gate system or as a flood control gate in a watercourse such as a navigation canal.

Description

[0001]This application is a continuation of, and claims the benefit of and priority to, U.S. patent application Ser. No. 16 / 079,541, filed Aug. 23, 2018, which itself is the United States National Stage of International Application No. PCT / US2017 / 019222, filed Feb. 23, 2017 which claims benefit of and priority to U.S. Provisional Application No. 62 / 298,815 Feb. 23, 2016. Each said application is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to large scale water control gates particularly suited for use as flood barriers in ship canals and for use as lock gates for facilitation navigation between pools of differing surface elevations.SUMMARY OF THE INVENTION[0003]The present invention is comprised of one or more bottom hinged water barrier gates in conjunction with restraining means to prevent overturning of the gates in response to differential water pressure. The gate panels preferably incorporate controllable ballast chambers used to el...
