Embodiment 1

[0032] Such as Figure 1 to Figure 4 As shown, a high-pressure-resistant shell of a submarine includes an outer shell 1 and an inner shell 2, the outer shell 1 and the inner shell 2 are both cylindrical, and the outer shell 1 is sleeved outside the inner shell 2. A number of supporting rib rings 102 are arranged between the outer shell 1 and the inner shell 2. The supporting rib rings 102 are evenly spaced along the axial direction of the outer shell 1. The outer diameter of the outer shell 1 is D, and the distance between the supporting rib rings 102 is L, and 2D≤L≤5D.

[0033] Between the inner side wall of the outer casing 1 and the outer side wall of the inner casing 2, there are uniformly arranged support grids. In this embodiment, the supporting grid is a regular hexagon, and the inner surface of the outer shell 1 is formed with a honeycomb-like hexagonal supporting grid to differentiate the shell, and the regular structure greatly enhances the local pressure bearing ca...

Embodiment 2

[0035] Such as Figure 5 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the supporting grid is a trapezoidal grid, and the trapezoidal grid is alternately arranged in front and back.

[0036] The manufacturing method of the high-pressure-resistant casing of the above-mentioned submarine comprises the following steps:

[0037] 1) The outer casing 1 is processed by precision casting or numerical control machining, and the inner side wall of the outer casing 1 is provided with a supporting rib ring 102 and a supporting grid;

[0038] 2) machining the inner casing 2 by means of precision casting or numerical control machining,

[0039] 3) Put the inner casing 2 inside the outer casing 1 , and weld and fix the inner casing 2 on the outer casing 1 through the plug welding hole 201 on the inner casing 2 .

Abstract

The invention discloses A submersible high-pressure house and a method for manufacturing that same including an outer shell and an inner shell, the outer shell and the inner shell are cylindrical, theouter shell is sleeved on the outer side of the inner shell, A plurality of supporting rib rings are arranged between the outer shell and the inner shell, The supporting rib ring is uniformly arranged along the axial direction of the outer shell, and a uniformly arranged supporting grid is arranged between the inner side wall of the outer shell and the outer side wall of the inner shell. The high-pressure-resistant shell of the submersible can solve the technical problem of low pressure-resistant strength of the shell of the existing submersible.

Description

technical field [0001] The invention belongs to the technical field of submarines, and in particular relates to a manufacturing method of a high-pressure-resistant shell of a submarine. Background technique [0002] At present, the status of submarines in the national defense marine strategy is continuously enhanced, and various types of submarines have been developed. With the continuous increase of the diving depth of the submersible, the hull of the hull in the underwater high-pressure environment often suffers from fracturing, flattening, and water leakage after large deformation. The shell of traditional submersibles is mostly cylindrical. In order to increase its pressure resistance, one way in the prior art is to design a supporting rib ring at a certain distance, but it increases the number and thickness of the rib ring too much. Not only does it increase the weight of the shell, but the shell between the rib rings is still the weakest place in pressure resistance; ...
