Problems solved by technology

Due to the existence of ring ribs, it is inevitable that stress concentration will occur near the ring ribs when subjected to external pressure, so most of the areas have not reached the yield strength of the material, resulting in damage to the strength of the compressive structure

Embodiment Construction

[0034] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as figure 1 with figure 2 As shown, the pressure-resistant structure of the deep-depth submersible of the present invention includes a left flange 1, an inner shell 2, an outer shell 3, and a right flange 4.

[0036] The pressure-resistant structure of the deep submersible according to the present invention is a combined structure, and the inner shell 2 is wound on the basis of the left flange 1 and the right flange 4.

[0037] Preferably, the inner shell 2 is made of carbon fiber composite material.

[0038] The shell 3 is rolled of titanium alloy plate and welded by longitudinal welds. The shrinkage force of the welded shell 3 makes its inner wall closely fit the ring ribs of the inner shell 2. The shell 3 is then connected to the left flange 1 through the circumferential welds on both sides It is connected with the right flange 4...

Abstract

The invention relates to a pressure-resistant structure of a large-depth submersible. The pressure-resistant structure is of a combined structure form, and comprises an inner shell, an outer shell, aleft flange and a right flange, wherein the inner shell is of a main force bearing structure, the inner shell is formed by winding on the basis of the left flange and the right flange, the outer shellis formed by rolling a titanium alloy plate and welding the titanium alloy plate through a longitudinal weld joint and is tightly attached to an inner shell ring rib, and the outer shell is connectedwith the left flange and the right flange through circumferential weld joints at the two ends. The inner shell is of a cylinder and outer ring rib structure, outer ring ribs are distributed at equalintervals, and the specific intervals are optimally configured according to the minimum stress criterion of a pressure-resistant structure when external pressure is borne. The inner shell and the outer shell are connected through the butt joint circumferential weld joint, the weld joint only bears tension and pressure, and the stress form is simple. The submersible has a large-depth pressure-resistant structure which is high in underwater pressure resistance, good in pressure-resistant stability, uniform in pressure-resistant stress, light in weight, high in specific strength, good in impact resistance, long in seawater corrosion resistance duration, long in service life, non-magnetic and good in concealment.

Description

Technical field [0001] The invention relates to the field of submersibles, in particular to a pressure-resistant structure of a large-depth submersible. Background technique [0002] Cylindrical pressure-resistant structures, including equal-walled cylindrical pressure-resistant structures and cylindrical pressure-resistant structures with ring ribs, have been widely used in aviation in the past few decades because of their light weight and excellent mechanical properties. , Aerospace, navigation and vehicle engineering and other fields. In the pressure-resistant structure of submersible pressure materials, the cylindrical pressure-resistant structure plays a major role and is used in various types of torpedoes, submarines, unmanned underwater vehicles (UUV), and underwater autonomous cable-free robots (AUV) And various products such as various underwater vehicles. [0003] Titanium alloys have the characteristics of high strength, good corrosion resistance, and high heat resista...
