Abstract

The invention provides an online monitoring device for axial deformation of a non-metal gathering and transportation pipeline, and solves the problems that an existing device for monitoring the axialdeformation of the non-metal gathering and transportation pipeline is high in cost, complex in monitoring device structure, incapable of monitoring in real time and incapable of being popularized in alarge range. The device comprises an axial deformation sensor base, an axial deformation sensor protection shell and a bending sensor, the axial deformation sensor base and the axial deformation sensor protective shell are buckled to form a hollow cavity and are in sliding fit with each other; the bending sensor is placed in the hollow cavity, one end of the bending sensor is connected with one end of the axial deformation sensor base or the axial deformation sensor protection shell, and the other end of the bending sensor extends to the hollow cavity and is connected with one end of the axial deformation sensor protection shell or the axial deformation sensor base after being bent in the hollow cavity; the two ends of the bending sensor are located on the same side of the axial deformation sensor base and the axial deformation sensor protection shell, and a wire groove is formed in the axial deformation sensor base or the axial deformation sensor protection shell.

Description

technical field [0001] The invention relates to a monitoring technology for the deformation of a non-metallic gathering and transportation pipeline, in particular to an on-line monitoring device for the axial deformation of a non-metallic gathering and transportation pipeline. Background technique [0002] Pipeline transportation has the advantages of large transportation volume, stability and continuity, low cost, less land occupation, and convenient maintenance. It is the main mode of transportation for natural gas, crude oil, and refined oil products in the modern energy industry. Since oil, gas and other multi-phase media transported by oil and gas gathering and transportation pipelines are flammable and explosive, and often pass through densely populated areas, once an accident occurs, it will cause huge personnel, economic losses and environmental pollution. Therefore, it is necessary to The monitoring of gathering and transportation pipelines, in particular, requires ...
