Embodiment Construction

[0030] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 and figure 2 In the shown embodiment, it mainly includes a central pressure-resistant shell 1, and at least two layers of outer pressure-resistant shells 2 are sheathed on the outer ring of the central pressure-resistant shell 1 in turn. Both the outer pressure-resistant shell 2 and the central pressure-resistant shell 1 are in the shape of a spherical shell.

[0032] The inner cavity of the central pressure-resistant shell 1 is used to store internal equipment and ensure the safety of people in the cabin. When the submersible is in operation, the central pressure-resistant shell 1 is kept airtight and the internal pressure is maintained at a standard atmospheric pressure.

[0033] Such as figure 1 and figure 2 In the shown embodiment, the outer pressure-resistant shell 2 located in the innermost layer can com...

Abstract

The invention relates to the technical field of ocean engineering, and in particular relates to a pressure-resistant structure suitable for deep diving and a floating and diving method of the pressure-resistant structure. The pressure-resistant structure comprises a central pressure-resistant shell body, the outer ring of the central pressure-resistant shell body is sequentially sleeved with at least two layers of outer pressure-resistant shell bodies, the outer pressure-resistant shell body located on the innermost layer can completely wrap the central pressure-resistant shell body, and the outer pressure-resistant shell body located on the outer layer in every two adjacent layers of outer pressure-resistant shell bodies can completely wrap the outer pressure-resistant shell body located on the inner layer; water inlet interlayers are arranged between the central pressure-resistant shell body and the adjacent outer pressure-resistant shell bodies and between any two adjacent outer pressure-resistant shell bodies, and water inlet holes are formed in the multiple outer pressure-resistant shell bodies. The pressure-resistant structure is compact and reasonable in structure and convenient to operate, and the sinking and floating operation space of a submersible under different use conditions is completely expanded through the pressure-resistant shells which are sleeved layer by layer and internal high-pressure water.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to a pressure-resistant structure suitable for deep diving and a method for floating up and down. Background technique [0002] Abyssal science is at the forefront of marine scientific research at this stage, and the importance of deep-sea submersible equipment has become increasingly prominent. At present, all countries have begun to use "full sea depth" as the design goal of the latest generation of submersibles. The pressure hull is the core component of the submersible, and its structural form and mechanical properties are issues that need to be focused on. The pressure hull plays a role in protecting the equipment inside the hull from damage due to seawater pressure. For manned submersibles, the pressure hull is closely related to the safety of the people in the cabin. As the main provider of buoyancy of the submersible, the pressure hull accounts for a large weight...
