Problems solved by technology

On the other hand, as far as the current technology is concerned, due to the limitation of the pressure bearing capacity of the underwater vehicle shell, we still do not have the ability to go to deep water, and there is still a big gap compared with the development of deep water technology in the world.

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] This embodiment provides a pressure-resistant shell of an underwater vehicle made of composite materials and its forming method. The shell is used as an installation platform for underwater detection equipment or other instruments and equipment that require isolation from water, and can withstand 40MPa (water pressure). Under 4000m) external pressure capability, and under the conditions of use, it is light in weight and has a certain impact resistance.

[0028] In this embodiment, the requirements for the physical size of the pressure-resistant shell are: the outer diameter is 760mm, the length is 1500mm (large volume), and the weight is required to meet the conditions of use; the working environment: work in seawater, and can withstand 40MPa external pressure Ability, at the same time have a certain impact resistance.

[0029] Based on the above cond...

Abstract

The invention discloses a composite pressure-resistant casing and a molding method thereof. The molding method includes manufacturing the pressure-resistant casing, which can work normally without visible deformation under deep water, by metal and polymer . The pressure-resistant casing is light in weight when the criteria of strength and rigidity are met. The pressure-resistant casing molded by the molding method comprises a metallic framework, a first glass fiber reinforced plastic layer, a titanium wire wound layer, a second glass fiber reinforced plastic layer, a carbon fiber layer and a protective layer, wherein the first glass fiber reinforced plastic layer, the titanium wire wound layer, the second glass fiber reinforced plastic layer, the carbon fiber and the protective layer are arranged outside the metallic framework at one step. The metallic framework can be adopted as the framework of the pressure-resistant casing and for reducing weight of the integral structure. By the integral member made of materials different in performances and features, internal stress can be ensured to uniformly distribute, and external impact can be borne to some extent.

Description

technical field [0001] The invention relates to a pressure-resistant casing and a forming method thereof, in particular to a composite material pressure-resistant casing forming and a method thereof. Background technique [0002] In order to safeguard national maritime rights and interests, it is imperative to develop marine high-tech equipment for both military and civilian use. From the analysis of domestic and foreign development trends in recent years, it is very important to develop a device that can be used at a depth of several thousand meters underwater, detect the deep sea surface or formation, and collect relevant ocean data. [0003] At present, the world's major shallow sea oil fields and continental shelf oil fields have been fully developed, and oil and gas development in various countries has gradually advanced to deep sea areas, and good economic benefits have been obtained. However, my country's offshore exploration and development are mainly in the shallow...
