Automatic waveguide signal acquisition device for intelligent pressure vessel

Abstract

The invention relates to an automatic waveguide signal acquisition device for an intelligent pressure vessel. The automatic waveguide signal acquisition device comprises two fixed components and a signal excitation terminal and a signal receiving terminal arranged in pairs. The signal excitation terminal and the signal receiving terminal are mounted on the respective fixed components. Each fixed component includes a guide rail, a drive mechanism and a mechanical handle. The drive mechanisms drive the mechanical handles to move along the guide rails. The signal excitation terminal and the signal receiving terminal mounted on the mechanical handles reciprocate between the surface of a pressure vessel and the guide rails. When the signal excitation terminal completely contacts with the surface of the pressure vessel, a signal is excited, meanwhile, the corresponding signal receiving terminal is in full contact with the surface of the pressure vessel to receive the signal, and the automatic acquisition of the waveguide signal is achieved. Compared with the prior art, the automatic waveguide signal acquisition device in the invention has high reliability and solves the problems that the bonded piezoelectric sheets is large in number, easy to debond, fragile and high in cost and the structural integrity is destroyed under the condition of on-line monitoring of the pressure vessel structure.

Description

technical field [0001] The invention relates to a guided wave signal acquisition device, in particular to an automatic guided wave signal acquisition device for an intelligent pressure vessel. Background technique [0002] Pressure vessels working in high-temperature, high-pressure, high-humidity environments are vulnerable to severe environmental threats, which will aggravate excessive deformation and cause fracture failure. Online monitoring of in-service pressure vessels, on the one hand, can detect defects in the equipment in time, eliminate potential safety hazards, and reduce the probability of malignant accidents; The detection method provides guidance, thereby saving inspection time and reducing economic losses caused by blind repair and scrapping. In addition to the pressure bearing capacity of ordinary pressure vessels, intelligent pressure vessels based on online monitoring technology also have the capabilities of perception, information processing and damage war...

Problems solved by technology

However, this method is costly, and the ceramic piezoelectric sheet is easily affected by the working environment and the structure is debonded and broken. In addition, the surface of the pressure vessel needs to be ground and polished during the bonding process of the ceramic piezoelectric sheet, which will damage the structural integrity.
