Problems solved by technology

The current deep-sea metal pressure-resistant structures often have a large total mass and cannot carry enough payload. In order to meet the buoyancy requirements, a large amount of deep-sea buoyancy materials need to be mounted on the outside of the pressure-resistant structure, which brings trouble to the operation.

Abstract

The invention relates to a deep-sea long-term working pressure-resistant composite structure and its manufacturing method, including a metal head, the shape of which is a part of a double-curvature body of revolution, and the upper part of the metal head is fitted with a metal preset Carbon fiber pressure-resistant shell, the metal head, metal pre-assembled parts and carbon fiber pressure-resistant shell are combined and installed to form an elliptical double-curvature structure of revolution, and the metal head and metal pre-set parts are sealed by a conical surface. It is locked with bolts and anti-loosening gaskets, and the outer surface of the carbon fiber pressure-resistant shell is coated with a polyurea waterproof coating. The invention has the advantages of light weight, tightness, good durability, etc., and can significantly increase the payload of deep-sea equipment; the structure presents a complete streamlined shape with one end pointed and one end blunt, and the resistance is small when moving vertically in water; in deep-sea work Keeping the tip upward is beneficial to reduce the acoustic target characteristics of the structure; the manufacturing method of the composite structure in the present invention has the advantage of low cost.

Description

Technical field [0001] The present invention relates to the field of deep-sea pressure-resistant structure technology, in particular a deep-sea long-term working pressure-resistant composite structure and a manufacturing method thereof. Background [0002] Deep-sea pressure-resistant structure is an important part of deep-sea underwater equipment, which plays a role in ensuring the normal work of internal equipment and the health of personnel. [0003] The design of the pressure-resistant shell has an important impact on the safety of underwater equipment, carrying capacity and human-machine environment. The pressure-resistant shell is a structure that withstands hydrostatic pressure, which requires good safety, reserve buoyancy, space utilization and other characteristics to improve the comprehensive performance of the submersible. [0004] Deep-sea pressure-resistant shells have been designed as spherical structures and cylindrical structures in the past, and generally do not u...
