The utility model relates to the technical field of drainage
pipe detection, in particular to a drainage
pipe detection extension device which comprises a main body, and an extension
assembly is arranged in the main body. According to the utility model, the
visual probe is used for replacing traditional manual work to complete identification, counting, measurement, defect detection and guide positioning of the pipeline,
product defect detection is realized by using a
visual function of equipment, a large amount of time and personnel cost can be saved,
automation and
assembly line work in the production process are realized, and the production efficiency is improved. Scratches, smudginess, missing, pits, cracks and the like of the pipeline can be detected accurately, the operation speed is high, the bent pipeline can be detected rapidly and conveniently through the shockproof hard rib hose, the pipeline detection range can be expanded and the detection
ductility can be improved through bidirectional stretching and retracting of the telescopic rod, and then accurate quantized data can be provided; the damage condition of the pipeline can be detected and identified accurately, the requirement on the material of the pipeline is avoided, and long-distance pipeline detection can be carried out.
