Embodiment Construction

[0014] From the mechanical design point of view, the key mechanical issues of the pressure vessel involve elastic instability and plastic yielding. From the perspective of elastic instability, the lattice material sandwich structure composed of three-dimensional space micro-truss structure has the characteristics of high specific stiffness, specific strength, and multi-functionality, which can effectively improve the buckling resistance of the pressure cabin structure. The structural design of the layered pressure compartment based on interlayer pressure can decompose the deep-sea ultra-high pressure and share it evenly between the inner and outer shells, significantly reduce the stress level of the shell, and improve the plastic yield safety factor of the pressure cabin , thereby effectively increasing the fatigue life. Therefore, the layered partial pressure chamber based on interlayer pressurization has broad development prospects.

Abstract

The invention discloses a layered pressure adjusting device for a bathyscaphe. The pressure intensity of the outside of the bathyscaphe is smaller or equal to 120 MPa, and the pressure intensity of the inside of the bathyscaphe is 0.1 MPa. The bathyscaphe comprises n layers of spherical shells, and n is an integer larger than one. The spherical shells have the same sphere center, the space of every two adjacent spherical shells has designated pressure intensity and is provided with fluid and injected with the designated pressure intensity through the layered pressure adjusting device. The layered pressure adjusting device is a device for adjusting the pressure through the pressure intensity of seawater. According to the layered pressure adjusting device for the bathyscaphe, the space of every two adjacent spherical shells is provided with the fluid and injected with the designated pressure intensity through the layered pressure adjusting device, and the layered pressure adjusting device is the device for adjusting the pressure through the pressure intensity of the seawater, so that power equipment does not need to be additionally arranged, and the weight of the bathyscaphe is not increased; and self adjusting of the pressure intensity of every two adjacent spherical shells can be achieved, the time cost and the manpower cost are reduced, and the reliability is higher.

Description

technical field [0001] The invention belongs to the technical field of deep-sea submersibles, and in particular relates to a layered pressure regulating device of the deep-sea submersible, which is mainly used for real-time adjustment of the filling pressure between two partial pressure layers of the deep-sea submersible. Background technique [0002] The structures of the pressure chambers of deep-sea manned submersibles developed in various countries are all single-layer spherical shells, and the material systems mainly include high-strength steel and titanium alloy. At present, the deepest dive is the "Deep Sea Challenger" of the United States, with a dive depth of 10,908 meters. The previous breakthroughs in the pressure chamber of deep-sea manned submersibles were mainly in two aspects: materials and processing accuracy. Taking the "Deep Sea Challenger" as an example, its pressure-resistant shell is made of steel, with an inner diameter of 1.1 meters and a thickness of...
