Shape measuring system of underground long pipeline

Abstract

The invention relates to a shape measuring system of an underground long pipeline. The shape measuring system is used for measuring the shape of the underground long pipeline along with the movement of an outside traction device. The shape measuring system comprises a measuring device, a mechanical casing and an upper computer, wherein the measuring device is used for continuously measuring the inclining angle data of the underground long pipeline, and storing the inclining angle data; the mechanical casing is positioned at the exterior of the measuring device, is used for protecting the measuring device and is connected with the outside traction device; the upper computer is used for reading and processing the inclining angle data stored in the measuring device, and visually displaying the shape of the underground long pipeline. Compared with the prior art, the shape measuring system has the advantages that the detection is accurate, the implementing is convenient, the displaying is visual, the cost is reduced, and the like.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a shape measurement system for long underground pipelines. Background technique [0002] With the rapid development of my country's economy, urban construction is becoming more and more perfect, and urban overhead pipelines are gradually transferred underground. Various and criss-crossing pipelines constitute an intricate underground pipeline network system. There are more and more types of pipelines, and the types and quantities of pipelines will also continue to increase. At present, there are mainly water supply management channels, drainage pipelines, power pipelines (including heat, gas compressed air, oxygen and acetylene pipelines), process pipelines, power and communication cables. The complexity of the underground environment and the intricate underground pipelines have brought many safety hazards to the construction and management of the pipelines. Every year...
