Device for measuring defect point of submarine pipeline

Abstract

The invention discloses a device for measuring a defect point of a submarine pipeline. The device for measuring the defect point of the submarine pipeline comprises a fixed cross rod, a fixed supportarranged on the fixed cross rod in a relative mode and a measuring rod arranged on the fixed cross rod in a sleeved mode, a movable support is arranged on the measuring rod in a sleeved mode, a radialmeasuring rod is arranged on the movable support, a depth measuring rod is vertically arranged on the radial measuring rod, and the installed radial measuring rod and the depth measuring rod are of across structure. During measurement operation, not only can the influence and limitation of environmental operation environments such as sea water tide and sea pipe damage media leakage are avoided,the measurement personnel are easy to operate, and the operation time is short; moreover, the relative zero point is stable during measurement operation, the damage point depth, the axial length and the radial length of the submarine pipeline are measured, and meanwhile, the reading is simpler.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for a defect point of a submarine pipeline. It belongs to the field of offshore oil engineering. Background technique [0002] In the maintenance process of submarine pipelines, due to external force factors such as anchoring and hooking of ships, deformation and damage of submarine pipelines often occur. At this time, it is necessary to measure and evaluate the deformation of submarine pipelines in service, and determine according to the measurement results Applicable emergency maintenance technical scheme for submarine pipelines. [0003] At present, when measuring and evaluating the deformation and damage of submarine pipelines due to external forces, rulers and squares are often used to measure the depth, axial length, radial length and other data of the damaged part of the submarine pipeline. However, due to the seawater tide where the submarine pipeline is located ...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and provide a kind of measuring device of the defect point of the submarine pipeline, which not only solves the need to simultaneously measure the depth and axial length of the damaged point of the radial submarine pipeline during the measurement operation , The problem of radial length measurement, so that the working environment is not limited by it; moreover, it also solves the problem of fixing the relative zero point to make the measurement reading more accurate
