摘要： The invention discloses an overshot control gate for use with trapezoidal irrigation channels. A gate has a rigid rectangular section adapted to, in use, be pivotally mounted to a base of a trapezoidal irrigation channel. A pair of triangular sections are pivotally mounted on opposite sides of the rigid rectangular section. Each of the triangular sections are divided into first and second triangular sections with a common apex at the base of the trapezoidal irrigation channel. Each of the first triangular sections are rigid and adapted to, in use, be pivotally mounted to opposite side walls of the trapezoidal irrigation channel. Each of the second triangular sections including the pivotal mounting on opposite sides of the rigid rectangular section are formed of a flexible material. Also disclosed is a pipe flow meter and a duckbill valve.

摘要： A vertically reciprocable gate assembly which includes a frame surrounding a port and a gate having a gate member connected by links to an actuating member which is slidably connected to the frame with the gate member between it and the frame. Unless the gate is closed, the gate member is held against the actuating member and out of sealing contact with the frame. When the gate is lowered, it engages a stop which establishes a predetermined position of the gate member relative to the port, further downward movement of the actuating member causes the links to thrust the gate member into its operative position.

摘要： A laterally sliding type opening/closing gate of a torsion structure of reasonable cost is implemented. The gate includes: the torsion structure having a closed cross-section consisting of a thin wall installed such that it may cross a sluice and be composed such that its cross-section may make an in-plane rotation around a restriction point on the cross-section and that a torsion moment generated by an applied load and reaction force on the restriction point is transmitted to its terminal due to its torsion rigidity; and a rail that is installed such that it may cross the sluice; and a plurality of axle type supports that has a function of a restriction point and moves along the rail.

摘要： A flow control device includes a float that moves vertically in response to changes in water level, a valve body that moves between extended and retracted positions, and a mechanism interconnecting the float and the valve body wherein changes of position of the float in response to changes in water level changes the position of the valve body. The valve body is placed adjacent a discharge pipe to change the effective intake area of the discharge pipe with changes in water level.

摘要： The present invention provides a water control system with the reservoir level versatility of a weir stack and the relatively easy drainage of a water control gate. Multiple stack beams constrained between two opposed guide channels create a fluid reservoir having an incrementally adjustable fluid level. Increasing or decreasing the reservoir level is a matter of adding or removing one or more stack beams. To create an opening for draining fluid from any level of the reservoir, a picker mechanism captures at least one of the stack beams. By lifting the captured stack beam, and any stack beams atop the captured stack beam, the picker mechanism opens a gate at any level of the reservoir through which fluid may flow.
