Application of industrial endoscope in sewage pipeline detection (municipal pipe network detection)
1Industrial endoscopy inspection
Industrial endoscopic detection technology is gradually applied to the camera inspection of pipelines, which solves the limitations of manual detection, reflects the operation status of pipelines more objectively, and improves the working environment of urban drainage pipeline inspection operators. Industrial endoscope inspection equipment consists of components such as camera, lighting, cable, display and control system. It is manually pushed into the sewer pipe to photograph and record the quality status inside the pipe. Mainly for small and medium sewage pipes above DN100
2 Electronic periscope detection technology
Electronic periscope is an inspection tool that combines mirror and TV inspection. It is mainly composed of controller, display, connecting cable, camera lens, lighting system, telescopic rod, etc. After the high-magnification camera is extended into the inspection well through the adjustable length telescopic rod, the high-quality spotlight and astigmatism light combined with the high-magnification zoom capability of the lens electronic camera make clearer image data for the drainage pipes within a certain distance.
3. Sonar detection technology
Sonar detection is a detection method that uses sound wave technology to detect and locate underwater objects in pipelines and other facilities. Using the principle that sound waves can propagate through water and meet solid reflections, the sonar head sends sonar signals to the pipe wall and receives reflected signals at the same time. The system distinguishes the strength of sonar signals by color, thereby distinguishing the contours of different media and simulating The cross-sectional view inside the pipeline is used to find out the internal condition of the pipeline through the cross-sectional view.
4 underwater robot
The pipeline robot used in the water detection technology is mainly aimed at medium and large sewage pipes above DN800, where the visibility of the water body is zero, and the digital detection is carried out under the operating state of half pipe or full pipe. The pipeline robot includes pipeline video, pipeline sonar, loader, control box, and wire reel (with meter counting function). The water detection technology can effectively overcome the problems of limited application scenarios of CCTV video detection technology, and provide more accurate disease location and measurement by replacing human operations with machines throughout the process.
