The invention relates to a fishtail type paddle thruster which comprises a base used for being fixed to a ship body, a rotating shaft vertically supported on the base and capable of rotating relative to the base and a vertical paddle board, a connecting rod extending transversely is fixed to the rotating shaft, and the fishtail type paddle thruster is characterized in that a limiting base is fixed to the connecting rod; the limiting seat is provided with a shaft hole extending vertically, a pin shaft is installed in the shaft hole, the paddle board is fixed on the pin shaft and located below the limiting seat, the pin shaft is further provided with a limiting piece, an arc-shaped moving space with the pin shaft as the circle center and a limiting part inserted into the arc-shaped moving space are arranged between the limiting piece and the limiting seat, and the limiting part is connected with the limiting seat. And the paddle plate rotates relative to the limiting seat in a range limited by the arc-shaped moving space through the pin shaft. The advancing power of the ship body comes from double acting force of flexible connection of water flow and the paddle plates and rigid connection of the rotating shaft and the paddle plates, under the same condition, the advancing speed of the ship body can be increased, and operation is easy.

    本发明涉及一种鱼尾式船桨推进器,包括用来固定于船体上的基座、竖向支撑在该基座上并能相对于基座转动的转轴以及竖立的桨板,所述转轴上固定有一横向延伸的连接杆,其特征在于:所述连接杆上固定有一限位座,所述限位座开有竖向延伸的轴孔,在该轴孔中安装有销轴,所述桨板固定在该销轴上并位于所述限位座之下,所述销轴上还设有限位件,所述限位件和限位座之间设有以销轴为圆心的弧形活动空间和插入到该弧形活动空间中的限位部,所述桨板通过所述销轴在该弧形活动空间所限定范围内相对于限位座转动。本发明使船体的前进动力来自于水流与桨板的柔性连接和转轴与桨板的刚性连接的双重作用力,在同等条件下,有助于提高船体的前进速度,且操作轻松。
