Description

Technical Field

[0001] The utility model relates to the technical field of boiler pipeline detection, in particular to a phased array detection device for power station boiler pipelines. Background Art

[0002] Generally speaking, power plant boilers are boilers used to generate electricity in power plants. There are two main types of power plant boilers: pulverized coal boilers and circulating fluidized bed boilers. These two types of boilers are the main types used in power plants. The biggest difference between fluidized bed boilers and pulverized coal boilers is the different fuel states, namely liquid and coal powder. Power plant boiler pipes are used to transport heat sources. Phased array detection technology is a non-destructive detection technology. Ultrasonic phased array detection technology uses multi-element transducers of different shapes to generate and receive ultrasonic beams. By controlling the different delay times of each element in the transducer array to transmit pulses, the phase relationship when the sound wave reaches a certain point in the object is changed, and the focus and sound beam direction are changed, thereby realizing ultrasonic beam scanning, deflection and focusing, which is used to detect power plant boiler pipes.

[0003] There is an existing phased array detection device for power station boiler pipelines (application number: 202321421747.5). A plurality of phased array detection probes are arranged on the detection ring outside the pipeline, which can detect the pipeline from multiple angles, fully detect the pipeline and improve the detection efficiency. The above problem still exists. When detecting the pipeline, multiple phased array detection probes are used for detection, and the conveying pipeline needs to be rotated at the same time to conduct a comprehensive detection of the pipeline. However, when conveying the pipeline, the pipeline needs to fit the two ends of the pipeline on the conveying rollers on both sides respectively. At this time, the position of the pipeline passing through the detection ring cannot be detected. When the port position is to be detected, the staff needs to hold the other end by hand to keep the pipeline in a horizontal state before detection. It is not convenient for the staff to conduct a complete detection of the pipeline and it is not convenient for the staff to use. When detecting the pipeline, the detection ring and the pipeline need to be in a concentric state, which is not convenient for the pipeline and the detection ring to be concentrically positioned, and it is not convenient for the staff to operate.
