The invention discloses a pump-jet propeller guide pipe connecting structure. The pump-jet propeller guide pipe connecting structure comprises a connecting flange; the connecting flange is arranged behind blades of the propeller and comprises a stern end flange and a bow end flange, and the diameter of the bow end flange is larger than that of the propeller. The stern end flange and the bow end flange are connected through a connecting bolt, and the stern section guide pipe and the bow section guide pipe are connected together. After the connecting flange is arranged on the propeller blade, the rigidity of the guide pipe near the propeller is improved, when the stern section guide pipe deforms, the propeller blade cannot be clamped, and the safety of a naval vessel is improved.
本发明公开了一种泵喷推进器导管连接结构,包括连接法兰;连接法兰安设在螺旋桨的叶片后,其包括艉端法兰、艏端法兰,且艏端法兰的直径大于螺旋桨的直径;艉端法兰、艏端法兰通过连接螺栓连接,将艉段导管、艏段导管连接在一起。本发明使连接法兰设置在螺旋桨叶片后,提高了螺旋桨附近导管的刚度,当艉段导管变形,也不会卡住螺旋桨叶片,提升了舰艇的安全性。
