Problems solved by technology

With the increase of the working depth of the submersible, the pressure body has large radial and longitudinal shrinkage deformation under deep sea pressure, which will implicate the longitudinal and transverse non-pressure structures welded on the pressure body, thus There are strength and stability problems, which are unfavorable to the ultimate bearing capacity of the pressure body

Embodiment Construction

[0024] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0025] Such as figure 1 , figure 2 with image 3 As shown, the plate spring pre-tensioning structure of the pressure-resistant body of the deep-sea submersible in this embodiment includes a pressure-resistant body 9, and the outer circumferential surface of the pressure-resistant body 9 and its spacer are sheathed with a non-pressure-resistant structure 10, One end of the non-pressure-resistant structure 10 extends the non-pressure-resistant structure inner panel 8. The non-pressure-resistant structure inner panel 8 is parallel to the outer surface of the pressure-resistant body 9; on the outer circumferential surface of the pressure-resistant body 9 and the non-pressure-resistant structure inner panel 8 There are multiple sets of pre-tightened assemblies installed between.

[0026] The structure of the single-group pre-tightening assembly is as follows: It include...

Abstract

The invention relates to a limiting and contraction distortion compensating plate spring pre-tightening structure for a pressure-resistant body of a deep sea submersible vehicle. The pressure-resistant body is included; the outer circumferential surface of the pressure-resistant body is sleeved with a non-pressure-resistant structure in a spaced mode; one end of the non-pressure-resistant structure extends to form a non-pressure-resistant structure inner surface plate; the plane of the non-pressure-resistant structure inner surface plate is parallel to the outer surface of the pressure-resistant body; and a plurality of pre-tightening assembling bodies are mounted between the outer circumferential surface of the pressure-resistant body and the non-pressure-resistant structure inner surface plate. The plurality of pre-tightening assembling bodies are mounted between the pressure-resistant body and the non-pressure-resistant structure inner surface plate, thus pre-bending of both wings of a plate spring exerts pre-tightening force on the pressure-resistant body for compensating for the radial contraction distortion of the pressure-resistant body in a submergence process, the rigidity of a whole structure is improved through limiting sleeves and pre-tightening bolts, and distortion of the pressure-resistant body under the action of eccentric load is limited.

Description

Technical field [0001] The invention relates to the technical field of deep-sea equipment pre-tightening devices, in particular to a plate spring pre-tightening structure for pressure-resistant body limit and contraction deformation compensation of a deep-sea submersible. Background technique [0002] The pressure-resistant shell structure of the submersible requires light weight, good economy, high structural efficiency and good reliability. When in use, it usually needs to be matched with a non-pressure-resistant shell. In the prior art, the non-pressure-resistant structure of the submersible is welded into a whole with the pressure-resistant body to provide an installation foundation for outboard equipment. As the working depth of the submersible increases, the pressure-resistant body has a large radial and longitudinal contraction and deformation under deep sea pressure, which will implicate the longitudinal and horizontal non-pressure-resistant structures welded on the press...
