The left and right human-powered devices are operated independently by a person's left and right hands, respectively.

The concrete structure of right propeller is: comprise main shaft, rotating disk, annular plate blade, draw bar, positioning bar and shell. The annular flat plate blade comprises identical arc-shaped bodies at both ends and two identical flat plates in the middle section. The aspect ratio of the annular flat blade is between 1 and 3. The gap between the two flat plates of the annular flat blade is slightly greater than the sum of the diameters of the positioning rod and the drawing rod, the height of the positioning rod is greater than three-fifths of the height of the annular flat blade, and the height of the drawing rod is greater than that of the annular flat blade. three-fifths of the height. The casing includes a left side plate, a bottom plate and a right side plate, the left side plate and the right side plate are vertically arranged, and the bottom plate is arranged horizontally. The positioning rod is located in the middle of the front and rear direction of the casing and is installed on the bottom plate of the casing near the left side plate. The positioning rod is arranged vertically, and the gap between the positioning rod and the left side plate is slightly larger than the diameter of the draw rod and a piece of the annular flat blade. The sum of the thicknesses of the plates and the gap between the positioning rod and the left side plate can ensure that the annular plate blades can flexibly move in a semi-circle in the housing. The annular flat blade is set on the positioning rod and is located inside the casing, and the annular flat blade is perpendicular to the bottom plate of the casing. The turntable is horizontally arranged above the flat blades, and guide rails, slide blocks and springs are installed on the turntable. The slide block cooperates with the guide rail, and the slide block can slide along the guide rail. The spring is set on the guide rail and is on the inner side of the slider.

The outer circumference of the track rolls.

A kind of manpower double-push boat of the present invention produces beneficial effect like this: the person of operation sits on the seat, shakes left manpower device and right manpower device with left hand and right hand respectively, and the power of left manpower device and right manpower device is transmitted to left hand manpower device respectively. The propeller and the right propeller make the left propeller and the right propeller work respectively. The left and right thrusters work the same way. The right propeller works like this. At first, the annular flat blade is at the frontmost position in the longitudinal direction, that is, the inner wall of the rear end of the annular flat blade is close to the rear edge of the positioning rod, the front end of the annular flat blade is at the forefront, and the left side of the annular flat blade Close to the right side of the left side panel of the enclosure. Looking down at the right propeller from top to bottom, the right hand shakes the hand crank mechanism counterclockwise, the power is transmitted to the main shaft through the power transmission device, and the main shaft drives the turntable to rotate clockwise. The semi-circular motion drives the annular flat blade to make a semi-circular motion in the shell, that is, the annular flat blade rotates half a circle around the positioning rod at the longitudinal front position and reaches the longitudinal final position, and then moves straight forward to the longitudinal front position, and then the annular flat blade Rotate half circle clockwise around the positioning rod again, and then move straight ahead to the longitudinal frontmost position, promptly got back to the original position. Then continue to repeat the above process periodically. In this way, the annular flat plate blades will continuously introduce the water in the front of the shell and then draw it to the rear to generate forward thrust. During the movement, the ring-shaped flat blades quickly open between the front and the left side panel of the shell and quickly close between the rear and the left side panel, producing the "jittery" and "sumo" movement effects similar to insects, and Due to the restraint of the casing and the turntable, the movement of the annular flat blades in the casing also produces a mirror effect, which can generate a large forward thrust. The blade of the left propeller moves counterclockwise in a semi-circle under the drive of the left manpower device, which also produces a large thrust forward. Because the left propeller and the right propeller operate independently, the manpower double-push boat does not need to be equipped with a rudder, and turning and retreating can be realized conveniently. The fast and slow movements of the left propeller and the right propeller can realize turning and driving. Changing the direction of motion of the blades can make the manpower double-push boat run backwards. If the blades of the left propeller and the right propeller move in the same direction, they can turn in circles. The manpower double-push boat of the present invention includes but not limited to the following advantages: small energy loss, high efficiency, flexible maneuverability, and the blades are easy to manufacture, and will not produce obvious wakes like propeller boats, nor will there be serious damage like traditional paddle steamers. The phenomenon of splashing water.
