    摘要: A fish diversion apparatus uses a plane screen to divert fish for variety of types of water intakes in order to protect fish from injury and death. The apparatus permits selection of a relatively small screen angle, for example ten degrees, to minimize fish injury. The apparatus permits selection of a high water velocity, for example ten feet per second, to maximize power generation efficiency. The apparatus is especially suitable retrofit to existing water intakes. The apparatus is modular to allow use plural modules in parallel to adjust for water flow conditions. The apparatus has a floor, two opposite side walls, and a roof which define a water flow passage and a plane screen within the passage. The screen is oriented to divert fish into a fish bypass which carries fish to a safe discharge location. The dimensions of the floor, walls, and roof are selected to define the dimensions of the passage and to permit selection of the screen angle. The floor is bi-level with a level upstream of the screen and a level beneath screen selected to provide a uniform flow distribution through the screen. The apparatus may include separation walls to provide a water flow channel between the apparatus and the water intake. Lead walls may be used to adjust water flow conditions into the apparatus. The apparatus features stoplog guides near its upstream and downstream ends to permit the water flow passage to be dewatered.

    摘要: A fish diversion system for a penstock housing a hydroelectric turbine employs large area screens to shunt fish to a bypass conduit above the turbine. The screens are disposed generally lengthwise of the penstock and inclined upwardly at a shallow angle to maximize water flow velocity along the screens while minimizing the approach velocity normal to the screens. Fish and debris are thus swept along the screens rather than impinged on them. One embodiment uses two screens set end to end. The upstream screen can be tiltable for cleaning. A second embodiment uses a unitary elliptical screen in a cylindrical penstock. The bypass conduit is sized and positioned to minimize bypass water flow volume while maintaining sufficient volume and velocity to discharge fish from the upper portion of the penstock. A funnel-shaped bypass manifold connects the penstock to the bypass conduit.

    摘要: This invention relates generally to rotary filter apparatus which are capable of removing solids from water currents, and more specifically to an endless filter belt comprising specially-shaped filter plates provided between wire ropes or screen plates and rockably fitted on transverse linking rods, with the wheels on both ends of the aforesaid linking rods being regulated to the track frame installed in and over the water channel as against the wheels on both ends of the interlocking rods linking the back ends of filter plates being regulated to the inner track frame having a track different from the former, thereby making sure to arrest, transport and dump the solids and recondition the spacings or meshes as the filter medium travels around.

    摘要: A device for protecting marine life from water intake ducts is presented. The intake duct enters the marine life protector which is characterized as an inner body of water separated from the main outer body of water by means of barrier walls. Through one or more of these barrier walls, input ducts are arranged which pass through the barrier walls having their longitudinal axes other than parallel to the free surface of the water bodies so that the input and exit orifices of the ducts are at different water levels. At least one of these orifices may be covered with a grating or screening or other additional protective means.
