Embodiment 1

[0057] figure 1 shown is a preferred embodiment provided by this application. In this embodiment, it includes four body spiral layers that are stacked and sleeved in sequence, namely the first body spiral layer 1, the second body spiral layer 2, the first body spiral layer 2, and the The diameters of the three-body spiral layer 3 and the fourth-body spiral layer 4, the first-body spiral layer 1, the second-body spiral layer 2, the third-body spiral layer 3 and the fourth-body spiral layer 4 gradually decrease in the direction of the central axis, At the same time, the column walls of the first body spiral layer 1, the second body spiral layer 2, the third body spiral layer 3 and the fourth body spiral layer 4 are concave and convex, and are wavy;

[0058] from Figure 3-Figure 4 It can be seen that when the body spiral layer is not bulging, it is a cylindrical structure. When it is bulged, the column wall of the body spiral layer is bent, forming a wave shape, and the degree ...

Embodiment 2

[0063] As can be seen from Example 1, the present application not only has a relatively large improvement in structure, but also has a unique feature in the process of manufacturing. Specifically, the manufacturing process in Example 1 is specifically described. figure 2 is the overall flow chart of the manufacturing process,

[0064] Step 1: Assemble the first body spiral layer 1, place the first spiral reinforcing tube 5 inside the first body spiral layer 1, and close to the inner wall of the first body spiral layer 1. At this time, the first body spiral layer 1 is Cylindrical structure, the first spiral reinforcement tube 5 and the first body spiral layer 1 are fixed by welding at the contact point. During welding, spot welding is used for positioning first, and then seam welding is used to fix the first spiral reinforcement tube 5 and the first spiral layer. The body spiral layer 1 is close to the weld to form the weld 8 shown in 3a; image 3 3b shown is a schematic view...

Abstract

The invention relates to a deep-sea laminated spiral pressure-resistant hull device and its manufacturing process. The pressure-resistant hull device includes several body spiral layers stacked in sequence, and the body spiral layers are coaxially arranged, that is, centered on the same center line. axis, and the diameters of several body helices gradually decrease toward the central axis; the body helices are cylindrical, and the cylindrical column wall is undulating in waves; they are respectively arranged in the cavities formed by adjacent body helices The helical reinforcing tube, the contact point between the helical reinforcing tube and the adjacent body helical layer is the position where the body helical layer protrudes toward the central axis; the compression resistance of the device of the present invention is improved to a certain extent, and the manufacturing cost is reduced at the same time.

Description

technical field [0001] The invention relates to a deep-sea laminated spiral pressure-resistant shell device and a manufacturing process thereof, belonging to the field of submersible pressure-resistant shells. Background technique [0002] With the continuous research in the shallow sea field, there is less and less space for us to explore, and the corresponding exploration of the deep sea is particularly important. the needs of the job and the proper functioning of the equipment. [0003] However, traditional pressure shells are limited to spheres, columns, cones, rings and their combined structures, which cannot optimally coordinate compressive capacity, space utilization, and hydrodynamic properties, and manufacturing is limited to compression molding, bending, and CNC turning. Other traditional crafts, high cost, long cycle and poor quality. SUMMARY OF THE INVENTION [0004] The invention provides a deep-sea laminated spiral pressure-resistant shell device and a manu...
