The invention provides an energy-saving appendage structure in front of a ship propeller. The energy-saving appendage structure comprises a main body, a connecting rod, a guide piece, a flow guide piece and a bottom plate; the front end of the main body is of a conical structure, and a paddle body is mounted at the front end of the main body; the main body comprises a paddle body and a connectingpiece; threaded holes are formed in the upper and lower ends of the main body; a connecting piece is arranged at the front end of the paddle body; the connecting piece is of a T-shaped circular structure; and the flow guide piece is used for being installed at the foremost end of the device. When the device is used, the device can be located at the foremost end through the flow guide part to guidewater flow, therefore, the pressure on the paddle body is reduced; and if an object is about to impact the propeller body, the object can be in contact with the propeller body through the flow guidepiece, the front end of the flow guide piece is of a wedge-shaped structure, and in the moving process of the ship, the flow guide piece can divide the object needing to impact the propeller body, sothat the object can be broken and flow towards the two sides, and the object is prevented from directly impacting the propeller body.
本发明提供一种船舶桨前节能附体结构,包括:主体,连接杆,导件,导流件和底板;所述主体的前端为锥形结构,且主体的前端安装有桨体;所述主体包括有桨体,连接件;所述主体的上下两端设有螺纹孔;所述桨体的前端设有连接件;所述连接件为T形圆形结构;导流件是用来安装在本装置的最前端的,使得本装置在使用的时候,可以通过导流件使本装置处于最前端将水流进行导流,从而减少桨体受到的压力,且若是有物体要撞击到桨体的时候,可以实现通过导流件与其接触,导流件的前端为楔形结构,在船只移动的过程中,导流件可以将需要与桨体撞击的物体进行分割,使得物体可以破碎,从而向两侧流动,避免物体直接撞击到桨。
