Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically to a non-destructive inner wall inspection device for municipal pipelines. Background Technology

[0002] Municipal pipelines are a crucial component of urban infrastructure, primarily used for transporting and discharging various fluid media within cities, including water, gas, heat, sewage, and rainwater. The planning, construction, and maintenance of municipal pipelines are vital for the normal operation and development of cities. During the design and construction of municipal pipelines, factors such as urban topography, landforms, population density, and economic development must be considered to ensure the safe, reliable, and efficient operation of the pipeline system. Simultaneously, it is necessary to strengthen the daily maintenance and management of municipal pipelines, promptly detecting and addressing issues such as leaks, blockages, and corrosion to safeguard public safety and environmental sanitation. During the production of municipal pipelines, the inner wall needs to be inspected. Ultrasonic testing can be used on the outside of the pipeline. Utilizing the propagation characteristics of ultrasound in different media, when ultrasound encounters defects in the inner wall of the pipeline, it undergoes reflection, refraction, and scattering. By analyzing the reflected wave signals, the presence of defects in the inner wall can be determined. This method is sensitive to internal defects and can detect even small defects such as cracks and holes; it can quantitatively measure the size and depth of defects; and it is highly adaptable to various pipeline materials, suitable for various metal and non-metal pipes.

[0003] The existing internal wall inspection device has been found to have blind spots during use, which means that some areas cannot be detected during inspection, thus compromising the quality of the pipeline. Therefore, it needs to be improved.

[0004] Therefore, it is necessary to invent a non-destructive inner wall inspection device for municipal pipelines. Summary of the Invention
