Embodiment Construction
[0021] The present invention will be described in more detail below in conjunction with the accompanying drawings:
[0022] combine Figures 1 to 8 , the present invention consists of two sub-paddles, respectively the first sub-paddle 2 and the second sub-paddle 4, the relative positions of the two are fixed, and the included angle θ is maintained at 60 to 90 degrees, so as to figure 1 The dashed line in the middle is the symmetrical axis distributed on both sides of the main shaft 1, each sub-paddle is equipped with a number of paddles 3 in parallel, and is connected to the main shaft 1 through the paddle shaft 6, the top of the paddle shaft 6 is a gear structure, and the inner chain of the main shaft 1. The tooth structure is connected to realize the free rotation of the paddle from 0 degrees to 90 degrees. Both ends of the main shaft 1 are gear structures, which are connected with the hull 5, and are reciprocating and swinging under the driving of the hydraulic transmissio...
