Abstract
A low-frequency acoustic wave generating device for detecting pipeline blockage related to the technical field of pipeline detection is provided and includes a sealing shell configured to be communicated with a pipeline, a sealed pressure environment is formed inside the sealing shell. A low-frequency electroacoustic transducer is disposed inside the sealing shell, the low-frequency electroacoustic transducer is connected to a signal generator and is configured to transmit an acoustic wave into the pipeline. The device transmits the acoustic wave signals to a high-pressure gas pipeline, combined with a signal generator capable of generating any waveform, thereby emitting any waveform of acoustic wave signal into the pipeline. The use of acoustic waves with special markings and characteristics for pipeline blockage detection can improve the anti-noise interference ability of the acoustic wave detection, and improve the precision of the detection.
