摘要： An automated water control device comprises a rotatable housing that can be incrementally positioned to control flow of water over an upper or weir edge of the housing. The device is installed at a control point in an impoundment area, such as a settling pond. The housing is selectively rotated to raise and lower the height of the weir edge to a target gate height. Automatic control is provided for operation of the device by a controller communicating with an actuator. A system of the invention includes one or more water control devices and the controller. A method of the invention includes controlling flow of water from an impounded water source by use of the automated water control device. Manual or semi-automated embodiments are also disclosed.

摘要： According to one embodiment, a flood vent includes a frame forming a fluid passageway through an opening in a structure. The flood vent further includes a door pivotally mounted to the frame in the fluid passageway for allowing a fluid to flow through the fluid passageway. The door has two opposing faces that include a first face and a second face. The flood vent further includes a first float positioned within the door in a location in-between the first face and a second float. Additionally, the first float is configured to allow the door to pivot in a first direction. The flood vent further includes the second float positioned within the door in a location in-between the second face and the first float. Furthermore, the second float is configured to allow the door to pivot in a second direction.

摘要： To provide a floating flap gate that requires an auxiliary force of a counterweight or the like, and in which bending does not occur in a forward end portion of a door body, even in cases in which an installation site has a wide span. A floating flap gate 1 having a forward end portion 2c of a door body 2 that is configured to rotate around a base end portion serving as a fulcrum at a time of a rising water, so as to float upwards, and provided with an upper beam 2d attached to the forward end portion 2c of the door body 2 and a door body suspension member 3 contained within the upper beam 2d, and having two ends each being connected to one end of a wire rope 4. A counterweight 5 is connected to the other end side of the wire rope 4 as a pulling device. Bolts 6b are used as adjusting members interposed between the upper beam 2d and the door suspension member 3, and are inserted into bolt holes 6a provided on an upper surface of the upper beam 2d, so as to exert an opposing force to the tension of the wire rope 4 resulting from the weight of the counterweight 5 acting on the door body suspension member 3, the opposing force being applied uniformly to the upper beam 2d during ordinary use.

摘要： A flood vent includes a door pivotable within a frame between a closed position and an open position. A fluid trigger that is triggerable by a fluid to allow the door to pivot from the closed position to the open position includes a retainer and a fluid modifiable material. The fluid modifiable material is positioned between the door and the retainer thereby obstructing the door from pivoting from the closed position to the open position until the fluid modifiable material is modified by contact with the fluid.
