Detection sensor stand

Abstract

The invention provides a detection sensor support which is arranged on a main body of an intelligent pig for petroleum pipelines and characterized in that: the detection sensor support consists of a sensor box, a Y-shaped support, an installing base of the Y-shaped support and a spring, wherein, the Y-shaped support is used for supporting the sensor box, the installing base of the Y-shaped support is used for arranging the detection sensor support on the main body of the intelligent pig, the spring includes a support spring and a pullback spring, and the two ends of the support spring are respectively connected with the installing base of the Y-shaped support and the Y-shaped support; the detection sensor support causes a detection sensor to realize the anticipated functions of pasting tightly, avoiding and detecting by the coordination of various components.

Description

technical field [0001] The invention provides a bracket, which is a component of an intelligent pig for long-distance petroleum and natural gas pipelines, in particular a mounting bracket for a sensor for detection of the intelligent pig for pipelines. Background technique [0002] The sensor bracket is an important part of the intelligent pig. It is generally required to achieve three functions. First, it must provide a mounting bracket for the sensor used for detection, which can replace the sensor and be safe and reliable when running in the pipeline; secondly, it is required to ensure that it can be used as a pig When running in the pipeline, the bracket mechanism can maintain a certain pre-tightening force so that the sensor can always be close to the inner surface of the pipeline at a fixed distance; finally, the sensor bracket must be easy to disassemble and distribute multi-channel sensor groups in a circumferential array, so that parts can be replaced and Omni-direc...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is also to design a novel intelligent pig detection sensor bracket, which concentrates on solving the technical problems in the following three aspects: the first is the functional problem. The invented sensor bracket can meet the requirements of installing the detection sensor and has the ability to maintain a certain adhesion force and The functional requirements of the detection distance; the second is that the structure is simple and reliable, easy to maintain and form an array. The invented sensor bracket can more conveniently form multiple sets of sensor arrays, has better adaptability to pipeline deformation and inner wall protrusions, and can be easily replaced Vulnerable detection components; the third is the problem of versatility, the invented detection sensor bracket can become a general installation platform for different non-excitation non-contact pipeline defect detection sensors
