Description

Pipeline ultrasonic inner detector working state detection device

Technical Field

The utility model relates to the technical field of pipeline ultrasonic internal detection, in particular to a device for detecting the working state of a pipeline ultrasonic internal detector.

Background

The pipeline ultrasonic internal detector is mainly used for detecting pipelines for conveying liquid media (mainly crude oil or finished oil) in long distance or gas conveying pipelines filled with the water media. The ultrasonic internal detector for the pipeline realizes corrosion or crack detection of the pipeline wall by exciting ultrasonic waves by using an ultrasonic probe. Because the pipeline ultrasonic internal detector has the characteristics of high detection precision, easy judgment of detection data, high detection confidence and the like, the pipeline ultrasonic internal detector has a vital position in pipeline integrity evaluation and is widely applied to the international and domestic pipeline internal detection industry.

Because the detection service in the pipeline has large implementation workload and has great influence on the operation of owners, the detection service in the pipeline is implemented by teams of more than ten people and more than ten people at a time, so that the reliability of the detection in the pipeline is very important. The ultrasonic internal detection of the pipeline which is invalid at one time not only causes huge waste of detection personnel, but also wastes the operation cost of the owners in the aspects of adjusting production and the like for matching with the internal detection. Thus improving the reliability of in-line detectors is of great importance in implementing in-line detection services.

Failure of in-line detector service is typically caused by malfunction or failure of the in-line detector. Thus, the inspection of the operating state of the in-pipeline detector is an important element in ensuring the successful implementation of the in-pipeline detection service.

The inspection of conventional ultrasonic in-line detectors is typically performed before the in-line detector enters the pipe. However, the operation of the inner detector by the operator after the inspection is finished can cause the failure of the inner detector, or the inner detector is not tightly sealed and the inner detector is pressurized to cause the failure of the inner detector. Meanwhile, if the gas in the pipeline is not discharged cleanly before the ball is launched, the ultrasonic coupling is affected, and the ultrasonic detection in the pipeline is also invalid.

As shown in fig. 1-5, in order to achieve the above object, the present utility model adopts the following technical solutions, including:

The ultrasonic detector 120 is arranged at the center of the supporting block 110 in a liftable manner, a probe 121 for being attached to the outer wall of the pipeline is arranged at the lower end of the ultrasonic detector 120, and the ultrasonic detector is used for receiving ultrasonic signals emitted by the inner detector 3.
