Application scenarios

Accurate leak detection: Accurate detection of small leak points, with higher leak detection accuracy than ground listening, gas tracer, correlation instrument and other technologies.

In-pipe exploration: Exploring conditions such as valve blockage and poor water quality that may be caused by the accumulation of foreign matter in the pipeline.

Routing reconstruction: applied to pipeline routing reconstruction operations due to lack of pipeline routing information due to age.

Restoration survey: Provide non-stop water and pressure in-line inspection and survey results for trenchless restoration decision-making and design.

Technical principles

High-sensitivity hydrophones and high-definition camera units are used to detect various abnormal conditions such as small leaks, damage, nodules, air pockets, and impurity accumulation, and precise positioning of abnormal points is achieved through the ground beacon system. Can also be used for pipeline route reconstruction jobs.

During detection, close the gate valve under the exhaust valve. After disassembling the exhaust valve, install the transceiver. Put the Diting detection robot into the transceiver, open the gate valve and push the robot into the pipeline. The robot moves along with the flow of water. In order to facilitate recycling, the Diting 60 product has an automatic umbrella retracting function. When the equipment is recycled, part of the parachute rope can be unlocked, which significantly reduces the water resistance and improves the recycling efficiency.

Main advantages

• Using a high-sensitivity audio collection system, the acoustic signal is transmitted back in real time;
• Equipped with a high-definition camera, the entire process can be visualized to ensure high detection accuracy;
• Efficient noise reduction algorithm effectively suppresses interference signals;
• Ultra-long detection distance, typical working conditions 2km, limit 6km
• Abnormal points/leak points can be accurately located, and suspicious locations can be repeatedly inspected.
• No need for pipeline downtime, minimal impact on water supply
• It can detect small leaks in pipelines, defects in the inner wall of pipes, pipeline routing, air pockets in pipelines, etc.
• Diting-30 can be equipped with standard valve injection port and fire hydrant injection port
