| 摘 要： | 针对小管道在役检测的特点，对旋转反射镜式传感器结构的不漏检条件进行了详细分析，并对单焦距超声传感器用于小管道在役检测时的相对误差进行了讨论；在超声检测分析的基础上，对旋转反射镜式传感器进行了结构设计，它由超声传感器、平面反射镜、旋转机构、微型电机和连接器等部件组成；小管道液浸超声检测室内试验表明，在适当的采样率和系统增益情况下，反射镜式超声传感器可用于小管道的在役检测。

| Abstract: | Aimed at the on-line inspection of small-diameter pipelines, the condition of complete coverage of circumference for the pipeline has been extensive studied for single ultrasonic sensor with a rotating planar reflector. Relative error has also been studied for the single focus ultrasonic sensor. Based on the ultrasonic analysis, the structure design for single ultrasonic sensor with a rotating planar reflector, which is made up of ultrasonic sensor, planar reflector, rotating part, micro-motor and links is given. The immersion test for small-diameter pipeline shows that single ultrasonic sensor with a rotating planar reflector are available for on-line inspection of small-diameter pipelines at the proper sampling frequency and system amplitude. |
