Pipeline detection device based on piezomagnetic effect

Abstract

The invention discloses a pipeline detection device based on a piezomagnetic effect. The pipeline detection device based on the piezomagnetic effect comprises a machine body outer shell, a main body running mechanism, a propeller motor mechanism, a plurality of driving connecting rod rolling wheel mechanisms, a plurality of driven connecting rod rolling wheel mechanisms and a plurality of signal acquisition processing mechanisms, wherein the machine body outer shell is formed by the connection of a machine body and a machine tail, and the main body running mechanism is arranged inside the machine body outer shell. The propeller motor mechanism is fixed on the tail portion of the machine body outer shell. The driving connecting rod rolling wheel mechanisms are evenly fixed on the machine tail of the machine body outer shell along the circumference, and the driven connecting rod rolling wheel mechanisms are evenly fixed on the machine body of the machine body outer shell along the circumference. Each driven connecting rod rolling wheel mechanism is connected with a signal acquisition processing mechanism through an internet data center (IDC) interface in a straight-inserting mode. The pipeline detection device based on the piezomagnetic effect can automatically conduct detection and positioning in long distance inside a pipeline where oil conveying work is not stopped. An important means is provided for nondestructive detection inside the pipeline, and the pipeline detection device based on the piezomagnetic effect plays a very important role in guaranteeing the pipeline safety and smooth and long-time running.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline detection, in particular to a pipeline detection device based on piezomagnetic effect. Background technique [0002] my country is a country with a large amount of energy, and it is also the country with the second largest energy consumption, and the energy consumption is on the rise. Therefore, under the promotion of such an environment, the oil storage and transportation technology has developed to a certain extent. The main method of oil storage and transportation in my country is pipeline transportation. Over the decades of reform and opening up, oil transportation pipelines have gradually become popular. Among them, oil transportation networks have been established in Northeast, Central South, Central and East China, especially in Northwest China. In addition, regional oil storage and transportation networks have been established in the Sichuan-Chongqing area and the area east of...

Problems solved by technology

[0004] Although traditional non-destructive testing (NDT) methods (ultrasonic, magnetic particle, penetrant, eddy current and ray, etc.) have been widely used in industrial testing, it has its limitations: (1) It can only find existing defects, and cannot detect and predict The part where the defect will occur cannot solve the sudden damage of the equipment; (2) the object under inspection generally needs to stop working during the inspection; (3) the surface of the object under inspection is pretreated by removing coating and polishing, which is inefficient and costly (4) The accuracy of the test results is affected by factors such as the shape and structure of the workpiece and the technical level of the personnel; (5) The working conditions of the on-site test are poor and the labor intensity is high, so it is difficult to avoid missing tests
