Description

Underground pipeline detects camera and puts in device

Technical Field

Background

With the continuous acceleration and deepening of the urbanization process, the security detection and the security assessment of the urban underground space are gradually emphasized. The urban drainage pipeline is used as an important component of an urban underground space, has the characteristics of perennial water flow, deep pipe burial, large section size, laying at each corner of a city and the like, and has the advantages that functional defects such as deposition, scaling and the like and structural defects such as cracking, deformation and the like easily appear in the pipeline along with the increase of the operation age, so that serious urban safety accidents such as ground collapse and the like are caused.

In the 70 s, the development of the petroleum, chemical, natural gas and nuclear industries and the need for pipeline maintenance stimulated the research of robots in pipes.

The problems of the wheel type pipeline robot such as motion interference in bending pipes and irregular pipelines in the practical application process, insufficient driving force caused by internal consumption, deviation from the correct posture of the robot in the pipeline, even rollover and jamming are caused by wall deformation and errors of the robot. Researchers at home and abroad mainly solve the problems in the structure, such as adoption of a differential mechanism, flexible connection and the like, and the existing pipeline internal exploration mode is high in manufacturing cost, more complex in structure and increased in cost.
