The invention discloses a positive pressure sealing cam type straight wing propeller with an adjustable blade installation angle and a method, and belongs to the technical field of ship propelling. The device comprises a propeller box body, a rotating assembly and swing rod blade assemblies, the rotating assembly is rotationally connected with the propeller box body, the multiple swing rod blade assemblies are evenly installed on a propeller rotating plate in a circumferential shape, multiple pneumatic connectors are installed on the upper box body, and compressed air can be conveyed into the propeller to achieve positive pressure sealing; the lower box body is provided with a kidney-shaped hole capable of adjusting the installation angle of the propeller, and the swing rod blade assembly is provided with a blade installation angle adjusting mechanism. The problems that the blade installation angle of an existing cam type straight wing propeller cannot be adjusted, the friction torque is large due to the fact that a lip-shaped sealing ring is adopted between a propeller rotary plate and a box body, and the overall installation angle of the propeller is difficult to adjust are solved.

    本发明公开了一种正压密封且叶片安装角度可调的凸轮式直翼推进器及方法,属于船舶推进技术领域。装置包括推进器箱体、转动组件和摆杆叶片组件,转动组件和推进器箱体转动连接,多个摆杆叶片组件呈圆周状均匀安装于推进器回转板上,上部箱体安装多个气动接头,可输送压缩气体进入推进器内部实现正压密封,下部箱体设有腰型孔可调整推进器安装角度,摆杆叶片组件有叶片安装角度调整机构。本发明解决了现有凸轮式直翼桨推进器叶片安装角度不可调节、推进器回转板和箱体之间采用唇形密封圈而导致摩擦扭矩大,推进器整体安装角度调节困难等问题。
