  • In-situ observation device for gas hydrates
    Patent number: 12188913
    Abstract: An in-situ observation device for gas hydrates includes a reactor, which includes a visual tube, a pulling rod, a temperature-controlled seed crystal rod and a spiral adjuster. An upper end and a lower end of the visual tube are respectively equipped with an upper end cap and a lower end cap. The upper end cap defines an air inlet, and the lower end cap defines a liquid inlet. An upper end of the temperature-controlled seed crystal rod is connected to an adjusting flange. The adjusting flange is connected to the spiral adjuster. A lower end of the temperature-controlled seed crystal rod hermetically passes through the upper end cap and is located in the visual tube. The temperature-controlled seed crystal rod defines a cooling liquid channel, and a cooling liquid inlet and a cooling liquid outlet, a seed crystal rod liquid inlet and a seed crystal rod outlet.

  • Low-frequency acoustic wave generating device for detecting pipeline blockage
    Patent number: 12013498
    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.
