Title:
METHOD AND SYSTEM FOR INVESTIGATING HIDDEN ENVIRONMENTAL HAZARDS OF UNDERGROUND SEWAGE PIPELINE
Document Type and Number:
WIPO Patent Application WO/2023/035290
Kind Code:
A1
Abstract:
A method and system for investigating hidden environmental hazards of an underground sewage pipeline. The method comprises: while peeking inside a pipeline, investigating a hidden environmental hazard of an underground sewage pipeline with the assistance of external soil monitoring and groundwater monitoring technology, wherein peeking inside the pipeline comprises: a robot performs image capture in the pipeline and stores images of a pipeline environment; transmitting the images back by means of a screen for analysis; and when a fault point is found, adjusting the angle of a robot to capture and locate the location of the fault point. A crawler-type underwater inspection robot and a suspension-type inspection robot are used to probe pipe sections of different flow rates respectively, so as to avoid the problem of the suspension-type robot being unable to locate a defective part due to a rapid water flow.
