Composite conduit of deep sea propeller

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of deep-sea thruster equipment, in particular to a composite material conduit of a deep-sea thruster. Background technique [0002] The duct is one of the main parts of the propeller, which plays an important role in protecting the propeller blades, sharing the load of the propeller and improving the efficiency of the propeller. [0003] Deep-sea thrusters are mainly used in deep-sea submersible platforms, mainly including HOV, AUV, ROV, etc. Commonly used conduit materials include metal, plastic materials, etc., and structural forms include hollow and solid, etc. The thrusters of deep-sea submersible platforms require excellent performance, Light weight, seawater corrosion resistance, etc. Metal materials are not suitable for application in deep-sea thruster conduits due to high density and electrochemical corrosion between different metals; plastic materials have low strength, so in order to meet the stren...
