Pipeline clogging point locating device

Abstract

The invention discloses a pipeline blockage point locating device, comprising a pigging ball, a GPS locator, an elastically retractable claw, an optical fiber sensor, a signal acquisition device, and a computer display device. The pigging ball is provided with a GPS locator and an optical fiber sensor The hole on the pigging ball is provided with an elastically retractable claw, the optical fiber sensor is connected to the computer display device through a signal acquisition device, the inner end of the elastically retractable claw is connected to the inner wall of the pigging ball through a spring, and the outer end of the elastically retractable claw is connected to the inner wall of the pigging ball The end is locked by a buckle and the outer wall of the pigging ball. The GPS locator includes a casing, and the casing is provided with a GPS chip, an RFID chip, an electronic compass chip, a control circuit board and a lithium battery. The invention has the advantages of simple structure, convenient and reliable use, accurate positioning, timely positioning and conduction, and strong practicability.

Description

technical field [0001] The invention relates to the technical field of pipeline blockage monitoring, in particular to a pipeline blockage point positioning device. Background technique [0002] Pipeline transportation is the main way of oil and gas transportation. Since the inside of the pipeline will be mixed with impurities such as soil, it must be pigged when it is put into operation. During the operation, the flow area of ​​the pipeline is reduced due to deposition and accumulation in the pipeline. Small, or even blockage, and these deposits will accelerate the internal corrosion of the pipeline, so the pipeline may need to be pigged after running for a period of time. The ball is stuck causing a blockage accident. [0003] Because the existing pipeline blockage positioning technology is not high enough, the staff cannot locate the blockage point in time, which greatly affects the pigging work progress and reduces its work efficiency.
