Problems solved by technology
[0002] Most of the traditional human-powered boats use hand-operated paddles, which are unstable in operation and can only be rowed by skilled people, and the efficiency is low; the traditional pedal boats with propellers are easy to drive, but the efficiency is low, and the manufacturing process of the propellers is complicated. Wakes will be generated during use; the plane of the blades of the propulsion device of the traditional paddle steamer always passes the rotating shaft, and there is a splashing phenomenon during use, the water splash is large, and the effective thrust does not exceed half a cycle, the energy loss is large, and the efficiency is low. loud noise

Embodiment Construction
[0018] The present invention is described by way of example in conjunction with the accompanying drawings. A blade rotary human-powered boat is composed of a hull 10, a front power system 1 and a tail power system 7.
[0019] Hull 10 adopts fiberglass to make.
[0020]The front power system 1 includes one group, two or more groups of hand-operated propulsion devices 2 with the same structure and function, and they are arranged on the hull 10 equidistantly with the tail power system 7; each group of hand-operated propulsion devices 2 Including: hand crankshaft 3, left propulsion device 4, right propulsion device 5 and seat 6. The specific structure of the hand propulsion device 2 is: the hand crankshaft 3 is arranged horizontally and perpendicular to the longitudinal symmetry plane of the hull 10, the left section of the hand crankshaft 3 is connected with the left side wall of the hull 10 through a bearing, and passes through the hull 10 The left side wall is exposed on the ...

A paddle rotation type man-powered boat belongs to the technical field of boats and ships. The paddle rotation type man-powered boat is composed of a boat body, a front power system and a tail power system. The boat body is made of a wood material, plastic rubber or glass steel; the front power system comprises one, two or multiple groups of paddle rotation type hand-cranking propelling devices which are same in structure and function and provide thrust to the boat; the tail power system comprises two independent paddle rotation type propellers located at the left and the right and same in structure and work principle; the tail power system is also used for controlling direction besides generating the thrust. The paddle rotation type man-powered boat in use has no obvious back trace and no serious thrashing phenomenon, is high in efficiency, has no big splash, and can be used as a waterborne transportation and used for physical recreation activities.
Description
technical field [0001] A paddle-rotating human-powered ship belongs to the technical field of ships, and in particular relates to a human-powered ship. Background technique [0002] Most of the traditional human-powered boats use hand-operated paddles, which are unstable in operation and can only be rowed by skilled people, and the efficiency is low; the traditional pedal boats with propellers are easy to drive, but the efficiency is low, and the manufacturing process of the propellers is complicated. Wakes will be generated during use; the plane of the blades of the propulsion device of the traditional paddle steamer always passes the rotating shaft, and there is a splashing phenomenon during use, the water splash is large, and the effective thrust does not exceed half a cycle, the energy loss is large, and the efficiency is low. loud noise. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of traditiona...
