Abstract

The invention discloses a labor-saving high-efficiency paddling device, which comprises a rotary shaft and a paddle. The paddle is dumbbell-shaped integrally and comprises a sliding section and blades disposed at two ends of the sliding section, a limiting relative rotation hole is disposed on the rotary shaft, the shape of the limiting relative rotation hole matches with that of the sliding section, and the sliding section can slide vertically in the limiting relative rotation hole. Due to action of self-gravity of the sliding section, the sliding section can slide in the hole, and accordingly stress action areas of the blades are increased during paddling. In addition, during rotation of the paddling device, the blades can be completely separated from a water surface at certain stages, accordingly upward floating counter force is overcome, and a water stopping surface stopping a ship from advancing is avoided. Accordingly, resistance generated by the blades is minimized, and action of thrust is maximized. Furthermore, the blades gravitationally slide in water, so that the problem of noise generated due to spanking water when the blades are used for paddling is solved. The labor-saving high-efficiency paddling device is applicable to equipment such as pedal amusement ships, water sports equipment and the like. Besides, by the aid of the labor-saving high-efficiency paddling device, power efficacy, comfortableness and stability of the ship are greatly enhanced.
