Therefore, there is an urgent need for an underground pipeline measuring device in the market.
[0003] However, the prior art still has the following problems:
[0004] First of all, most of the existing underground pipeline measurements are carried out by blowing balloons with fans.

In addition, due to the limited wind force of the fan, it is impossible to measure longer underground pipelines, resulting in low applicability of the device.
[0005] Secondly, most of the existing underground pipeline measurements are conducted when measuring old pipelines. The device is located inside the pipeline. Because the inside of the pipeline is uneven, the device is very easy to tilt during measurement, resulting in inaccurate subsequent measurement results. Utility Model Content
