A pressure-resistant cabin for deep sea and its preparation device and preparation method

Abstract

The invention relates to the field of deep-sea submersible vehicles and specifically discloses a deep-sea compressive cabin and a preparation device thereof and a preparation method thereof. The deep-sea compressive cabin comprises a cabin body, an external protective layer and connecting sleeves, wherein the external protective layer is arranged outside the cabin body in a sleeving manner; the connecting sleeves are arranged at the two ends of the cabin body; reinforcing ribs are uniformly arranged on the internal wall of the cabin body; the reinforcing ribs comprise transverse reinforcing ribs and vertical reinforcing ribs which are arranged perpendicular to each other; the cabin body is a carbon fiber cabin body; and the connecting sleeves are titanium alloy connecting sleeves. According to the deep-sea compressive cabin, by using the cabin body made of a carbon fiber material, the thickness of the cabin body is reduced on the premise of guaranteeing the equivalent structural strength so that the use cost is greatly reduced; and by arranging the reinforcing ribs on the internal wall of the cabin body and using the titanium alloy connecting sleeves, the compression strength, stability and safety of the compressive cabin are improved. According to the deep-sea compressive cabin, the safety performance of a traditional compressive cabin is effectively improved, and the production and machining efficiency of the deep-sea compressive cabin is further enhanced.

Description

technical field [0001] The patent of the present invention relates to the field of deep-sea devices, in particular to a pressure-resistant chamber for deep-sea and its preparation device and method. Background technique [0002] At present, all countries in the world are increasing the development and utilization of marine resources, and the requirements for ocean inspection and monitoring are also getting higher and higher. Research work such as exploration and development of marine resources has gradually moved from shallow sea to deep sea, and the development of marine resources has become an inevitable choice. The pressure chamber of marine exploration instruments is a watertight pressure chamber that provides installation space for electronic devices, power supplies and other instrument units. It is the basic condition for ocean exploration and the development of marine resources. The key issues of the pressure-resistant cabin of marine exploration instruments are the ...

Problems solved by technology

When the pressure tank of this structure is at a large sea depth, due to the increase in the thickness of the wall, the overall weight is heavy, which affects the control of the weight and buoyancy of the pressure tank at a large depth, resulting in the safety of this type of pressure tank. Low

[0005] In addition, the inner wall of the existing pressure chamber is generally a smooth circular cylinder, while the traditional winding mold for the pressure chamber is a steel circular mold with a smooth outer circle, which is conducive to demoulding. When the outer surface of the pressure chamber is processed into a shape corresponding to the inner wall of the pressure chamber, the demoulding process cannot be formed, which ultimately leads to low production and processing efficiency of the pressure chamber

[0006] In summary, the safety performance of the existing deep-sea pressure chambers is low and the production and processing efficiency of the existing deep-sea pressure chambers is low
