Crest Gate Operating System
US Patent:
5538360, Jul 23, 1996
Filed:
Mar 2, 1992
Appl. No.:
7/844825
Inventors:
Henry K. Obermeyer - Fort Collins CO
International Classification:
E02B 720
US Classification:
405115
Abstract:
A crest gate has movable panels controlled in position by inflatable bladders. Air pressure to the bladders or from the bladders is provided to a control system that automatically regulates panel position. Air is bubbled out of a line that is normally below the water level behind the dam and crest gate panels. An actuator assembly is coupled to a valve for selectively venting the bladders. An elastomeric tire is used to create a positioning effect on the valve such that the control system maintains a precise water level. The gate configuration is improved to resist higher loads.
Crest Gate Operating System
US Patent:
5092707, Mar 3, 1992
Filed:
Oct 25, 1990
Appl. No.:
7/603655
Inventors:
Henry K. Obermeyer - Fort Collins CO
International Classification:
E02B 720
US Classification:
405 92
Abstract:
Several panels are pivotably mounted on top of a dam spillway for movement by air pressure provided through bladders downstream of these panels. The bladders are made from an elastomeric sheet that is folded so that edge portions overlap one another. A clamping bar secures these overlapping portions to the dam spillway. The sheet is also secured to the panel and defines the pivot or hinge joint for the panel. Abutments or stops on the clamping bar engage a strap, that also secures the bladder to the panel, so that the panel will not move upwardly beyond a limit position. An air operating system is disclosed for moving the panels in response to changes in the height or head of water upstream of the panels.
