The invention provides a rudder ball thrust fin capable of being rotatably retracted and released, and belongs to the field of ship hydrodynamic energy-saving devices. The problems that under the working condition that a ship sails at a high speed, resistance generated by an existing rudder ball thrust fin may exceed propelling benefits brought by the existing rudder ball thrust fin, so that the overall resistance is increased, and the energy-saving effect of the rudder ball thrust fin is lost are solved. The rudder comprises a rudder body, a shaft and gear integrated rudder ball, thrust fins, a shaft and gear integrated rudder blade, a rudder ball rotating mechanism and a rudder blade rotating mechanism, the thrust fins are arranged on the two sides of the shaft and gear integrated rudder ball, and the shaft and gear integrated rudder ball is rotationally arranged on the rudder body; thrust fin grooves are formed in the positions, at the upper end and the lower end of the shaft-gear integrated rudder ball, of the rudder body, the two thrust fins are matched with the two thrust fin grooves in an embedded mode respectively, and shaft-gear integrated rudder blades are arranged on the outer sides of the thrust fin grooves in a rotating opening and closing mode. The device is mainly used for a ship hydrodynamic energy-saving device.
本发明提出了一种可实现旋转收放的舵球推力鳍,属于船舶水动力节能装置领域。解决了现有舵球推力鳍在船舶高速航行的工况下,推力鳍所产生的阻力可能会超过其带来的推进效益,这将导致总体阻力的增加,从而使舵球推力鳍失去节能效果的问题。它包括方向舵舵体、轴齿一体舵球、推力鳍、轴齿一体舵叶、舵球旋转机构和舵叶旋转机构,所述轴齿一体舵球的两侧均设置有推力鳍,所述轴齿一体舵球转动设置在方向舵舵体上,所述轴齿一体舵球的上下两端的方向舵舵体上均设置有推力鳍槽,两个所述推力鳍分别与两个推力鳍槽内嵌入配合,所述推力鳍槽的外侧转动开合设置有轴齿一体舵叶。它主要用于船舶水动力节能装置。
