Abstract
A ship propulsion device is composed of a disc-shaped box, a direct-current motor and a control device thereof, a mechanism composed of synchronous pulleys and a synchronous driving belt, synchronous pulley supporting shafts and a plurality of blades disposed outside the box. When the direct-current motor disposed at the center of the disc-shaped box is driven by the control device to revolve clockwise, a synchronous pulley Z [planet] in the box is driven to revolve anticlockwise at the same time on its axis under the effect of a synchronous pulley Z [planet] supporting shaft and a synchronous pulley Z [sun]. A ship is paddled with highest efficiency and pushed forward by the uniformly-arranged blades disposed at the two sides of the disc-shaped box and fixedly-connected with the bearing shafts, with the blades always being perpendicular to water level as blades at one side of the box fall and blades at the other side rise. Because the propulsion device always moves in the top layer of the water, sludge, muddy water and dregs under the water can not be affected to float to the top layer. Therefore, the propulsion device is both energy-saving and environment-friendly.
