with the continuous exposure of various pipeline problems to the public, more and more people realize the importance of regular inspection of pipelines. pipelines can be seen everywhere in our daily life. if we do not strengthen the maintenance and management, it is likely to cause some adverse consequences, such as pipeline blockage, rupture, corrosion and so on. let's look specifically at the benefits of regular pipeline testing.
observe the water level of olfactory wells between the same pipes to determine whether the pipes are blocked. the water quality composition of the smelly well was observed, such as the normal rainwater and sewage from the upstream olfactory well and the yellow mud water from the downstream olfactory well, indicating that there was fracture or collapse in the middle of the pipeline. clean up the car (cattle). road cracks or collapses, and excavation inspection.
this method is blind to a certain extent, not only expensive, but also can not correctly evaluate the situation in the pipeline.
pipeline tv detection is known as pipeline closed-circuit tv detection in foreign countries, which is an advanced and effective means to detect pipeline condition in the world. in the past two years, some cities in china, such as shanghai, guangzhou and shenzhen, began to introduce this kind of detection system, and achieved good results.
the system consists of three parts: main controller, control cable rack and robot crawler with camera lens. the main controller can be installed on the car. the operator controls the speed and direction of the crawler in the pipeline through the controller, and controls the camera to transmit the video image in the pipeline to the display screen of the main controller through the cable. the operator can detect the internal state of the pipeline in real time, record and store the original image, and make further analysis.
