The X7 system employs sonar technology to accurately detect structural defects below the waterline (e.g., deformation, collapse, cracks, scaling, concealed branch connections) and functional defects (e.g., sediment buildup, floating debris), with measurement and analysis enabled via mouse tools. Simultaneously, CCTV video inspection captures conditions above the waterline. Integrated with PipeSonar and PipeSight software, the system enables imaging display, data editing, 3D modeling, and report generation, including outputs such as structural defect analysis, sediment profile diagrams, and silt volume calculations.
A key innovation is its dual-mode synchronous acquisition:
The sonar unit scans at 30 cross-sectional profiles per second to map pipeline contours.
The CCTV unit records 25 frames per second of above-waterline footage.
Data streams are synchronized via precise timestamps to ensure spatiotemporal consistency of inspection results.
When pipelines are fully or half-filled with water and cannot be drained, traditional CCTV video inspection methods struggle to deliver effective results. The X7 Pipeline Profiling Sonar Imager is specifically designed for such scenarios (applicable to pipelines or culverts with diameters or cross-sectional sizes ≤6000mm, regardless of material).
The CCTV-Sonar Floating Inspection System comprises five core components: a sonar probe, 360° rotating camera, cable reel, adaptive floating carrier, PipeSonar sonar imaging analysis software, and PipeSight video interpretation/reporting software. Combining sonar imaging and CCTV video technologies, the system integrates an underwater sonar scanning unit and an above-water video unit into a single floating device. It can be propelled through pipelines (fully or partially filled) via crawler robots or manual towing. A laptop or dedicated controller serves as the main terminal, enabling real-time data display and storage via wireless (or optional wired) connectivity.
