[0071] The working principle of the utility model is as follows:

[0072] During the measurement process, the sonar probe 1 is used to transmit signals and receive signals returned by the manhole wall to obtain relevant information in the pipeline.

[0073] The utility model adopts an acoustic method to detect the internal conditions of a pipe or a well filled with liquid, and uses sound waves to detect and locate underwater objects. It does not need to drain the liquid inside the pipe by using a pipeline camera detection method, and can obtain relevant data such as damage and siltation inside the pipe filled with liquid. Different from the pipeline periscope detection system that looks directly in front of the pipeline, the sonar probe "looks" at the pipe wall at right angles to the pipeline. When passing through the pipeline, the sonar probe rotates rapidly and displays each cross section of the pipeline. The sonar uses color to indicate the intensity of the echo reflected from the pipe wall, and these echo intensities indicate the type of surface (hard or soft). Red is used to indicate a strong echo signal, blue is used to indicate a weak echo signal, and the colors between the two indicate the corresponding echo signal intensities in proportion.

[0074] Since the sonar probe rotates 360° per second, the usual detection method is to use the sonar beam to depict a spiral circle inside the pipe. The moving speed of the sonar probe depends on the pipe diameter and the size of the defect to be detected. For a given range, 250 samples are always collected, so a fixed range corresponds to a fixed resolution. For example, at a range of 250mm, the longitudinal resolution is 1mm. The size of the scanning area on the inner wall of the pipe depends on the transducer beam angle, that is, the angle at which the energy attenuates by 3db. The beam angle of the sonar probe is 0.9deg, so the beam diameter is 4.8mm at a range of 250mm and 57.6mm at a range of 3000mm.

[0075] The utility model has a simple structure and a reasonable design. It adopts an acoustic method to detect the internal conditions of a pipe or a well filled with liquid, and uses sound waves to detect and locate underwater objects. It does not need a pipeline camera detection method to drain the liquid inside the pipe, and can obtain relevant data such as damage and siltation inside the pipe filled with liquid.

[0076] It should be noted that all the electronics involved in the present invention adopt the existing technology, and the above-mentioned components are electrically connected, and the control circuits between the components are the existing technology.
