Cable trench inspection robot

The invention relates to a cable trench inspection robot, which comprises cable inspection equipment, a head body, at least two rollable annular bodies and a cylindrical body; at least one end of thecylindrical body is connected with the head body; the cable inspection equipment is installed at the end, away from the cylindrical body, of the head body; and the annular bodies are arranged on the cylindrical body. As the rollable annular bodies are arranged in the structure of the cable trench inspection robot in the method, the advancing mode is that the head body controls the annular bodies to roll so as to enable the cable trench inspection robot to move, the structure and mode of wheel drive advancing in a traditional mode are replaced, and the annular bodies roll so as to drive the inspection robot to move; the cable trench inspection robot can be widely applied to a complex cable trench terrain environment, the situation that due to the fact that the road condition of a channel ofa cable trench is complex
