Positioning device for pipeline blockage points

Abstract

The invention discloses a positioning device for pipeline blockage points. The positioning device for the pipeline blockage points comprises a spherical pig, a GPS positioner, an elastic storage type claw, a fiber optic sensor, a signal collection device and a computer display device. The GPS positioner and the fiber optic sensor are arranged on the spherical pig, the elastic storage type claw is arranged in a hole in the spherical pig, the fiber optic sensor is connected with the computer display device through the signal collection device, the inner end of the elastic storage type claw is connected with the inner wall of the spherical pig through a spring, the outer end of the elastic storage type claw is locked with the outer wall of the spherical pig through a buckle, the GPS positioner comprises a shell, and a GPS chip, a RFID chip, an electronic compass chip, a control circuit board and a lithium battery are arranged in the shell. The positioning device for the pipeline blockage points is simple in structure, convenient to use, reliable in use, accurate in positioning and strong in practicability, and capable of positioning in time and performing breakover.

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.
