The invention provides a telescopic propeller hub cap fin for a ship, and belongs to the field of ship propulsion. The problem that a traditional hat fin is poor in full-voyage energy-saving effect is solved. The propeller comprises a propeller hub, wherein a plurality of blades are uniformly distributed on the periphery of the propeller hub; the propeller hub cap is arranged at the rear end of the propeller hub; the multiple fin blades are arranged in one-to-one correspondence with the paddles, and all the fin blades are in sliding connection with the propeller hub; and the hydraulic adjusting device is arranged in the propeller hub cap and is used for driving each fin blade to extend out of or retract into the propeller hub. The device is mainly used for changing the operation state of the propeller.

    本发明提出了一种可伸缩船用螺旋桨毂帽鳍,属于船舶推进领域。解决传统帽鳍全航程节能效果差的问题。它包括桨毂,桨毂上圆周均布设置多个桨叶;螺旋桨毂帽,设置在桨毂后端;鳍叶,设置有多个并与每个桨叶一一对应设置,全部鳍叶均与桨毂滑动连接;和液压调节装置,设置在螺旋桨毂帽内用于驱动每个鳍叶从桨毂内伸出或缩回。它主要用于改变螺旋桨的运行状态。
