Along with the vigorous urbanization process, various hidden safety hazards that have not existed before have also followed. The city management department has given the urban underground space sufficient attention because of the risk of major accidents such as ground collapse. As a part of the underground space, various types of underground pipelines are prone to functional defects and rupture and deformation problems, which can cause accidents. For this reason, it needs regular inspections. At present, closed-circuit television inspection robots are commonly used to conduct internal pipeline inspections. Today, let's take a look at the main content that it can inspect.
Routine testing can detect hidden or unidentified maintenance wells or pipe sections in the drainage system, find and determine the source and connection of illegal sewage discharge, and directly detect the confluence of discharged sewage and sewage that needs to be treated; pipeline siltation, poor drainage, and other reasons; CCTV pipe inspection equipment to detect corrosion, damage, interface dislocation, siltation, sewage leakage, and pollution of the pipe. At the same time, it can handle the complete acceptance of new drainage systems and complete acceptance of drainage system transformation or dredging, etc.
The detection defects of the drainage pipeline of the CCTV pipeline inspection equipment can be divided into two categories. Structural defects include rupture and deformation, corrosion, misalignment, ups and downs, disconnection of interface materials, the hidden connection of branch pipes, foreign body intrusion, leakage, etc.; It is a functional defect, including six types of deposits and scales, obstacles, tree roots, residual walls, dam roots, heads, and scum. Usually, we use clock notation to express the location of the defect surrounding the pipeline.
We discovered major structural defects in the pipeline, such as third and fourth-level rupture and dislocation deformation, as well as other major types of defects that caused the ground collapse, using the closed-circuit television inspection robot, which we combined with surface detection technology to analyze the impact of the defects on the ground collapse and evaluate the effect of the defects. The hazards of ground collapse provide an essential technical basis and data for detecting, detecting, and managing hidden dangers of ground collapse.
In addition, this pipe inspection equipment can also be used for daily inspections inside the pipeline. The specially designed CCTV inspection robot has solid off-road ability, can pass through most obstacles, and automatically inspect according to the preset route. It can also send back audio, and video videos in real-time and automatically identify and analyze some hidden dangers and abnormal points and pass these abnormalities to relevant staff.
The CCTV inspection robot of Easysight uses sonar imaging technology and CCTV video detection technology. The underwater scanning unit (sonar head) and the water detection unit (rotating lens) are placed on the water surface (whole or half pipe) inside the tube. Use crawler or manual drag method to drive (sliding, floating) to move in the pipeline. You can use a personal laptop or a dedicated controller to control our underground pipe inspection camera.
