An Archimedes screw device for power generation or material handling has a number of helical pipes supported around a central support structure. The helical pipes may be formed from pipe portions that are joined together and wound around the central cylinder. Attached to the upper end of each helical pipe are feeder members (scoops) that together form an annular aperture feeding the helical pipes. The number of feeder members and pipes is selected depending upon the design flow of the device. This enables a standard kit of central support and pipe portions to produce e.g. a water turbine with a fully annular inlet, regardless of the number of helical pipes selected for a particular installation, by providing different feeder members for respective numbers of helical pipes. |
