The invention relates to a connecting structure between a full-revolving propeller and a ship body, which is characterized in that a platform-shaped connecting structure with a drop-shaped upper section and a drop-shaped lower section is arranged between a full-revolving propeller body and a main ship body; the upper section is connected with the main hull, and the lower section is connected with the upper end of the full-revolving propeller body. A plate-shaped fin is added at the rear end of the platform body, and the lower boundary of the fin is as high as the lower section of the platform body and can extend to the tail end of the main hull. The problems that the immersion depth of a propeller is not enough, blades are prone to water outlet and galloping and the course stability is not enough in a common installation mode of the full-revolving propeller are solved, the defects of the two installation modes can be well overcome by adding an independent connection structure capable of being provided with a fin plate, and the course stability of a ship can be properly improved. The optimal balance among the ship resistance, the propeller immersion depth and the course stability can be achieved, and the optimal effects of increasing the immersion depth, controlling the resistance and improving the course stability are achieved. The size is small, the structure is simple and processing is convenient.
本发明涉及一种用于全回转推进器与船体间的连接结构,在全回转推进器本体和主船体之间,设有上截面和下截面呈水滴形的台体状连接结构;上截面与主船体相连,下截面与全回转推进器本体上端相连。在台体后端增加一块板状鳍,鳍的下边界与台体下截面高度一致,可延伸至主船体末端。解决了全回转推进器的常用安装方式存在螺旋桨浸没深度不够、易叶片出水“飞车”、航向稳定性不够的问题,通过增加一种可附带鳍板的单独连接结构,能较好地解决两种安装方式的弊端,并可适当改善船舶航向稳定性。能取得船舶阻力、螺旋桨浸深和航向稳定性之间的最佳平衡,起到增加浸深、控制阻力、改善航向稳定性的最佳效果。体积小巧,结构简单,加工方便。
