The invention relates to a composite conduit of a deep sea propeller. The composite conduit comprises a metal sleeve, a hub body is installed on the outer surface of the metal sleeve in a matched mode, a plurality of supporting frames are evenly arranged on the outer surface of the hub body in the circumferential direction at intervals, conduit rib plates are installed on the heads of the supporting frames through bolts, and the conduit rib plates are wrapped with conduit skin. A plurality of through holes are formed in the conduit skin and connected with a conduit cavity and the outer side ofa conduit, so that pressure inside and outside the conduit is balanced. The conduit is compact and reasonable in structure and convenient to operate, the conduit is made of carbon fiber which is resistant to seawater corrosion, high in strength and small in density, the structural design of conduit hollowing is carried out, and the purposes that the propelling performance of the conduit is not affected and pressure balance inside and outside the conduit can be met are achieved through the design of conduit outer skin holes; and the conduit mounting hole adopts a metal sleeve form, so that processing, manufacturing and mounting are facilitated. By means of the design, the weight of the catheter can be reduced by over 50% under the condition that all aspects of performance of the catheter are not affected.

    一种深海推进器复合材料导管,包括金属套筒,所述金属套筒的外表面配合安装有毂体,所述毂体的外表面圆周方向均匀间隔设置有多个支撑架,所述支撑架的头部通过螺栓安装有导管筋板,所述导管筋板的外部包裹有导管蒙皮,所述导管蒙皮上开有多个通孔,通孔连接导管腔体和导管外侧,使得导管内外压力平衡。本发明结构紧凑、合理,操作方便,导管采用碳纤维这种耐海水腐蚀、强度高、密度小的材料,进行导管空心化的结构设计,通过导管外蒙皮开孔设计达到既不影响导管的推进性能,又能够满足导管内外受压平衡的目的,导管安装孔采用金属套筒的形式,方便加工制造与安装。通过这样的设计在导管各方面性能不受影响的情况下可以减重50%以上。
