Water wheel drive system for generation of electrical energy has blades on periphery of impeller each consisting of two pivoting blade leaves in pairs beside one another

摘要

A water wheel (1) for the drive of generators for the generation of electrical energy has a rotor driven by an impeller with blades on the periphery. The impeller axis is located transversely to the flow direction of the water and the turbine thus designed works entirely below water. The blades located on the periphery of the impeller consist each of two blade leaves (3). The blade leaves are located in pairs beside one another and are limited in pivoting fashion around a blade axis vertical to the impeller axis. This is so that when the peak of the blade axis points against the flow direction or has exceeded this point in the direction of rotation in an acute angle, the blade leaves unfold from one another and include an obtuse angle up to 180 degrees. When the peak of the blade axis points in the flow direction or has exceeded this point in the direction of rotation with an acute angle, they fold together and lie in a plane within five degrees from the vertical to the impeller axis.
