Description

Endoscope apparatus, for water supply facilities, to use without suspension of water supply and method for detecting pipe route using the same}

The present invention relates to a water pipe endoscope apparatus and a pipeline investigation method using the same. More specifically, by inserting an endoscope camera into the pipeline, the situation in the pipeline can be accurately grasped without interruption of water supply, and withdrawal of sediment in the pipeline. Not only can it improve the quality of the water, but also analyze the sediment's components to accurately diagnose the contributors and countermeasures for the pipeline, thus reducing the maintenance cost of the pipeline and providing the basic data for improving the future construction quality. The present invention relates to a water supply endoscope device and a pipeline investigation method using the same.

At present, the water supply in Korea has a high proportion of old water pipes that are not replaced, and there are related problems such as water quality and leakage. In other words, the water quality is contaminated when the water is transferred by the water pipe due to corrosion in the pipe, generation of foreign matter, foreign matters, and peeling of the coating, and the cost may be wasted due to leakage or foreign substances or bacteria may be sucked in from the leak point. There is this.

For the maintenance of such water supply facilities, conventionally, after a certain period of time after installation of the water supply pipe, there was a method of unconditionally replacing or photographing the inside of the pipe using X-rays.

In particular, as a leak detection method, first, when a sound generated by a leak is delivered to the surface, the sound is detected and amplified from the ground and listened by a receiver or analyzed by a meter to detect a leak. There is a method of installing a water detection sensor on the outside of the pipe to detect water leaked to the outside when the leak occurs.

However, the image obtained by X-ray imaging is not only uncertain but also cannot be photographed when the water pipe is plastic coated, and the detection method of the fresh food can be detected only when a certain amount of leakage occurs. It is almost impossible to detect where the traffic is frequent, and the moisture detection method has a problem that it is not easy to install a moisture sensor outside the pipe because the soil itself contains moisture.

In addition, in the conventional method, there is a case in which the inspection must be performed after stopping the flow of water supplied to the pipeline. When the water is cut, it causes a huge loss of various industrial facilities as well as inconvenience of the public. The impact on society is great.
