" style="box-sizing: border-box;background: transparent">Periscope for pipeline inspection Detection (Pipe Quick View Inspection) is a pipe periscope detection method in the inspection wells, called QV detection. QV detection is a kind of pipeline endoscopy technology. It not only solves the problem that camera distance can not meet the requirement of pipeline length and upload rate is too slow to synchronize, but also can accurately judge pipeline material defects, corrosion degree and specific location, and its detection results can be used as evaluation basis for pipeline health condition.   

QV technology principle

Video recording is used to monitor and record the internal deposition, pipeline breakage, foreign body penetration, leakage and branch pipe connection. It can clearly and clearly observe and record all the internal conditions of the pipeline, and then the video will be stored in the main control plane. The professional personnel will analyze all the video data one by one, systematically and thoroughly understand the basic situation of the pipeline, understand the drainage quality and operation, and the location of the outlet and the damage degree of the pipeline, write the pipeline inspection report, provide an economic and efficient detection method for the maintenance and repair of the pipeline.   

The QV detection system is mainly composed of three parts: the main controller, the hand-held pole for installing the camera, and the cable for connecting the main controller and the portable pole. The main controller can be fastened to the operator's chest with a straps. The operator can adjust the camera's free rotation, lens stretching, shooting and observation synchronously by regulating the main controller, and the original video data are kept in the main controller for further analysis.   

QV technical working procedure

QV technology work procedure detection procedures include: collecting existing pipeline information, work plan design, site exploration, internal industry data analysis, writing report. According to the actual situation, adjustments can be made. In some cases, for example, when the well is full of water, to advance the QV work, the valve must be adjusted to lower the water level to less than half of the nozzle.  

QV technology video analysis method

The key work of QV technology is to analyze the video data and see whether there are defects, types, levels and numbers of defects in the pipeline.   

QV technology provides a simple, intuitive and effective detection method for the present situation of urban pipe network system. It provides a scientific and effective basis for the management and maintenance of urban pipe network, and ensures the stable operation and development of the city. QV pipeline endoscopy technology not only plays a huge role in the detection of urban pipe network, but also has obvious application effect in other areas, such as power, petrochemical, aerospace and other fields.
