Water wheel with extended vanes

Abstract

A water wheel with extended vanes is disclosed. The water wheel characterized in that the rotating shaft of the water wheel is supported by bearing and a hub is mounted to the rotating shaft, a plurality of vanes are provided on the rotating shaft, and one end of each vane is connected to a connection shaft, where the other end of the connection shaft is connected to A blade, the side of the tail section of the blade is provided with a pulley which contacts with a cam when the vanes are lifted up, the cam includes a section of sliding face to drive the pulley so that the vanes and blades are in a straight line, and the bottom of the cam has a linking shaft to support and secure at the body of the water wheel. The increased arm of the vanes will effectively increase the driving force of the water wheel.

I claim:  
     
         1 . A water wheel having extended vanes characterized in that the rotating shaft of the water wheel is supported by bearings and a hub is mounted to the rotating shaft, a plurality of vanes are provided on the rotating shaft, and one end of each vane is connected to a connection shaft, where the other end of the connection shaft is connected to another vane, the side of the tail section of the vane is provided with a pulley which contact with a cam when the vanes are lifted up, the cam includes a section of sliding face to drive the pulley so that the vanes are in a straight line, and the bottom of the cam has a linking shaft to support and secure at the body of the water wheel.  
     
     
         2 . The water wheel having extended vanes of  claim 1 , wherein the connection shaft has a support shaft as the rotating shaft and at one side mounted the vanes is provided with a protruded block, the other side of the rotating shaft secured another vane is provided with another protruded block, thereby when the vanes move to a straight line, the protruded blocks are supported such that the connection shaft cannot be swung in one direction.  
     
     
         3 . The water wheel having extended vanes of  claim 1 , wherein the length of the vanes matches the depth of water.  
     
     
         4 . The water wheel having extended vanes of  claim 1 , wherein the vanes are a hollow body partially contained a fluid.
