Abstract

The invention provides a multi-element sensor embedding and protecting method for gathering pipeline monitoring. The method solves the problem that in an existing pipeline monitoring method, when monitoring sensors are installed on the surface of a pipeline, installation is simple and crude, positioning performance is poor, and mutual interference between the sensors and circuits is prone to occurrence, and protection is lacked. The method comprises the following steps that 1) multi-element sensor mounting and protecting units with the required sizes are machined, wherein in the case of each unit, the unit comprises a mounting block, a wire passing hole, a connecting lug and two connecting plates, the connecting lug and the two connecting plates are located at the two ends of the mountingblock correspondingly, the distance between the two connecting plates is matched with the width of the connecting lug, and the outer side faces of the two ends of the connecting lug and the inner walls of the two connecting plates are provided with mutually matched clamping groove structures, the mounting block is provided with a first pipeline sensor mounting clamping groove, and a second pipeline sensor mounting clamping groove is formed in the mounting block; 2) the number of the multi-element sensor mounting and protecting units is selected; 3) the sensors are installed; 4) the multi-element sensor mounting and protecting units are linked; and 5) various signal and circuit lines of the sensors are led out.

Description

technical field

[0001] The invention relates to a sensor installation and protection method for gathering and transportation pipeline monitoring, in particular to a multi-element sensor embedding and protection method for gathering and transportation pipeline monitoring. 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 real-t...
