The detection of the inside of the pipeline is mainly carried out by adopting the engineering truck, and the detection device is only suitable for monitoring large-scale pipe galleries and cannot be well suitable for detecting underground pipelines.

13. A method for detecting an underground water supply network by using the pipe damage detection device according to any one of claims 1 to 12, comprising the steps of:

step 1, supporting and placing a pipe damage detection device in a pipeline:

In the using process, a worker firstly adjusts the plurality of support assemblies (2) and the driving assembly (6) to the inner diameter of the adaptive pipeline through control, and then the pipe damage detection device is integrally put into the pipe;

step 2, walking control of the pipe damage detection device in the pipeline:

after the pipe damage detection device is stably supported in the pipeline, a worker drives the transmission gear (64) to rotate by controlling the driving motor (65), and drives the driving wheel (66) to rotate in the process of rotating the transmission gear (64), so that the driving wheel (66) drives the transmission belt (67) and the driven wheel (63) to rotate, and the two transmission gears (64) are in a meshed state, when one transmission gear (64) rotates, the other transmission gear (64) and the driven wheel (63) synchronously drive, and the pipe damage detection device is driven by the pipe damage detection device;

Step 3, detecting cracks in the pipeline:

When the whole pipe damage detection device moves in the pipe, a worker drives the crack detection assembly (4) and the hole breaking detection assembly (5) to rotate synchronously by controlling the transmission assembly (3) to rotate; in the process that the crack detection assembly (4) integrally rotates, fluorescent liquid is coated on the inner wall of the pipe through the liquid adding assembly (7) and the brush head (43), then in the process that the crack detection assembly (4) continuously rotates, the fluorescent liquid attached to the inner wall of the pipe is cleaned by the cleaning roller (44) and the CCD camera (45), at the moment, if cracks exist in the pipe, the crack part cannot be cleaned by the cleaning roller (44), so that the cracks can be well revealed under the irradiation of the ultraviolet lamp (46), the CCD camera (45) can identify the cracks, then a transmission signal is sent to the controller, and the crack part is recorded for subsequent repair treatment;

step 4, detecting a hole in the pipeline:

In the process of rotating the broken hole detection assembly (5), the mounting frame (51) drives the detection rod (52) to rotate, so that the detection rod (52) can be always attached to the inner wall of the pipe, the plurality of detection rods (52) can generate the same pressure to the supporting spring (53) and the pressure sensor (54), and the condition indicates that the inside is not broken; when the inner wall of the pipe is greatly damaged, the detection rod (52) can slide into a damaged hole under the action of the supporting spring (53), and the pressure sensor (54) can receive a signal of pressure change and transmit the signal to the controller, so that accurate positioning detection of the hole is realized.
