Abstract

The invention relates to a pull rod type underwater structure deformation measuring device comprising a cylindrical housing, a guide block, a sealing end cover, a spring sheet, a drive screw, a pressure compensating cavity and a straining sheet group. The device is compact and reasonable in structure and convenient to manufacture and operate; the components, such as the cylindrical housing, the guide block and the sealing end cover, are made of stainless steel, the cylindrical housing is fulfilled with transformer oil, the pressure of the oil in the cylindrical housing and the external high water pressure are balanced through the pressure compensating structure, tightness processing is performed on the measuring straining sheet group, and the measuring straining sheet group is guided out of the housing through a watertight connector. The structure is small, installation is facilitated, and the structural deformation can be measured on deep-sea high pressure water environment conditions.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a rod-type underwater structure deformation measuring device. Background technique [0002] The structural deformation of underwater pressure-resistant structures in the deep-sea high-pressure environment and the coordination of deformation between structures cannot be ignored. It is necessary to conduct research on structural deformation and deformation coordination design methods, and carry out corresponding test verification. In the test verification, it is of great significance to accurately measure the structural deformation of the pressure-resistant structure in the high-pressure water environment. [0003] In the prior art, the structural deformation analysis of the pressure-resistant structure in the high-pressure water environment mainly uses finite element analysis software to perform simulation calculations under the determined structural size and design pres...
