Submersible observation window pressure test device and method

Abstract

The invention belongs to a glass test technology, and particularly relates to a submersible observation window pressure-resistant test device and a submersible observation window pressure-resistant test method. The submersible observation window pressure resistance test device comprises a mechanical pressurization device, a glass test clamp, a sensor and an environment box. A servo hydraulic universal testing machine provides mechanical pressure, the mechanical pressure is transmitted to a testing clamp through a pressing rod and a pressing disc, the testing clamp is composed of a pressing head and a base, a glass sample piece is arranged in the base, the whole clamp containing the glass sample piece is arranged in the center of the pressing disc, and the mechanical pressure is transmitted to the clamp through the pressing disc and then transmitted to the glass sample piece through the clamp. A sensor can be laid on the inner surface of the glass sample piece. And the whole pressed part is arranged in the environment box. According to the invention, the size of the real submersible observation window is reduced according to a certain proportion, a scaled glass sample piece is processed, hydrostatic pressure conversion calculation on the observation window under the service condition is converted into mechanical load for testing, and various service conditions of the observation window glass can be simulated quickly, safely, accurately and economically.

Description

technical field [0001] The invention belongs to the glass test technology, and in particular relates to a pressure-resistant test device and method for an observation window of a submersible. Background technique [0002] The observation window of a manned submersible is the most direct way to observe the deep sea environment, and it is also the only non-metallic structural part on the submersible. Ensuring its safety and reliability is the key technology for deep sea manning. During the service process, the observation window glass may suffer from extrusion deformation and creep deformation due to the action of deep sea water pressure. In severe cases, the window may be extruded from the window seat, resulting in sealing failure, or even glass damage resulting in failure of the protective function. as a result of. [0003] The common test method to verify the safety and reliability of the observation window glass is to simulate its service condition under the condition of ...
