Trash Racks for Water Intake (fine)
Protect the turbine from small debris. Making a fine trash rack to stop branches and small debris
The fine trash racks are used to protect the turbine from small debris. They can also, in some cases, prevent fish or eel to pass through it. The spacing may vary from 20 to 100mm. Carbonneau Group developed a method to assemble laser-cut blades using tie rods, thus allowing to easily replace blades when damaged and to vary the width of the grid. An access door for divers can also be easily added.
