Background technique

As is known to all, the paddle wheel, also known as the paddle wheel propeller, is a propulsion tool for ships that uses the paddle wheel to rotate and the blades to divert water to propel the ship. The paddle propeller advances one step further than the propellers such as paddles and rafters. However, it is cumbersome and inefficient. Because more than half of the parts are exposed to the water surface, the driving bearing is subjected to large resistance during stroke and the blade is less stressed. The length of the blade is generally less than one third of the diameter of the paddle wheel, and the center of gravity is higher from the horizontal plane, which affects the navigation stability of the ship. At present, the propeller type propulsion device requires power equipment to have high-speed rotating power, and the power equipment requires relatively large output power, and the propeller type propulsion device is not suitable for low-speed power equipment, and is not suitable for human power driving.

detailed description

The structure of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments of the invention:

Referring to Fig. 1, the present invention includes a blade drive shaft 1 having a left blade rocker arm 21 disposed on the left end of the blade drive shaft 1, and a left blade link shaft 31 disposed on the left blade rocker arm 21 The left blade connecting shaft 31 is movably connected to the left blade 41; the right blade of the blade driving shaft 1 is provided with a right blade rocker arm 22, and the right blade rocker arm 22 is provided with a right blade connecting shaft 32, and the right paddle The blade connecting shaft 32 is movably connected to the right blade 42; the angle between the left blade rocker arm 21 and the right blade rocker arm 22 is 180 degrees.

A shift lever drive shaft 5 parallel thereto is disposed directly above the blade drive shaft 1, and a synchronous transmission mechanism 6 is disposed between the blade drive shaft 1 and the shift lever drive shaft 5, and the synchronous transmission mechanism 6 is a chain synchronous transmission. Mechanism or gear set synchronous transmission. a left-hand lever rocker arm 71 having the same length as the left blade rocker arm 21 is disposed on the left end of the lever drive shaft 5, and the left-hand lever rocker arm 71 is provided with a left-stop lever 81 for blocking the reverse rotation of the left blade 41; On the right end of the bar drive shaft 5, a right bar rocker arm 72 having the same length as the right paddle rocker arm 22 is provided, and the right bar rocker arm 72 is provided with a right bar 82 for blocking the reverse rotation of the right paddle 42. The distance between the blade drive shaft 1 and the bar drive shaft 5 is slightly larger than the lengths of the left and right

blade rocker arms

21, 22, as long as the blade drive shaft 1 and the bar drive shaft 5 are not obstructed from obstructing the left and right paddles. The

arms

21, 22 or the left and right bar rocker arms 71, 72 can be rotated; the lengths of the left and

right paddles

41, 42 are greater than the spacing between the blade drive shaft 1 and the bar drive shaft 5, and the top of the left paddle 41 The side is movably connected to the left blade connecting shaft 31, and the top side of the right blade 42 is movably connected to the right blade connecting shaft 32.

The working principle of the present invention is first described with reference to Fig. 1. If the traveling direction of the ship 91 is forward, the state of Fig. 1 is the initial state of the force of the left blade 41, and the right blade 42 is in a freely movable state when the blade is driven. The shaft 1 and the shift lever drive shaft 5 rotate clockwise, and the left blade shaft motion path 92 and the right blade shaft motion path 93 both move relative to each other around the blade drive shaft 1 while the left shift rod movement path The 94 and right bar motion paths 95 are relatively circumscribed around the bar drive shaft 5 . Referring to FIG. 2, in the process in which the blade drive shaft 1 and the shift lever drive shaft 5 are rotated clockwise by 60 degrees, the left shift lever 81 supports the left blade 41, and the left shift lever 81 and the left blade connecting shaft. Under the cooperation of 31, the left blade 41 moves rearward in a vertical state, and the left blade 41 is pushed forward as a whole under the reaction force of water; at this time, the right blade is still in a free state. Referring to FIG. 3, after the blade drive shaft 1 and the lever drive shaft 5 are rotated 180 degrees clockwise, the left blade connecting shaft 31 reaches the last end position of the blade drive shaft 1, and is left in this cycle. The paddle 41 can no longer continue to dial water under the force state. Thereafter, as the blade drive shaft 1 and the bar drive shaft 5 continue to rotate, the left paddle 41 loses the support of the left bar 81 and becomes free. At the same time, the right blade 42 begins to be subjected to the force-removing state, and is initially supported by the right bar 82. Under the reaction force of the water of the right blade 42, the present invention advances as a whole. As shown in FIG. 4, during the simultaneous rotation of the blade drive shaft 1 and the bar drive shaft 5 by 270 degrees clockwise, the right blade 42 remains stressed, and the left blade 41 remains in a free state until after 360 degrees of rotation. Make adjustments to the next drive cycle.
