1. A power operated wicket gate device having a structural box containing a hydraulic operating system which operates a wicket gate disposed to constitute the top surface of said structural box when in fully lowered position supporting traffic loads from above, and assume a number of predetermined angular positions about a horizontal shaft attached to said structural box, said operating system comprising:
strut hinged at the underside of said wicket gate at one end disposed to prop said wicket gate at a multitude of angles corresponding to different flood protection levels and other extremity pivotally supported on wheels running on horizontal rails on the floor of said structural box with movement of said wheels on said rails changing the prop angle of said wicket gate enabling said wicket gate to be lowered and raised; a hydraulic cylinder and piston horizontally mounted and fixed to the floor of said structural box, said cylinder and piston having an operating rod attached to said wheels enabling controlled movement of said wheels on said rails to lower and raise said wicket gate, a hydraulic power system that powers said hydraulic cylinder and piston, said hydraulic power system comprised of an electrical motor connected to a hydraulic pump in communication with hydraulic fluid, a locking mechanism disposed to secure said wheels in place at predetermined positions allowing said wicket gate to stay raised at said predetermined angular positions with power turned off, said locking mechanism snapping to unlocked position once said wicket gate is raised passed maximum height permitting lowering of said wicket gate, and snapping back to locking position once said wicket gate is fully closed, an external cord that supplies electrical power to said wicket gate assembly. |
