[0002] With the construction of distribution networks, there are more and more cable channels in cities, and the workload of cable survey is increasing. At present, when surveying cables, operators need to enter the cable well to see the cable pipes clearly. However, due to the poor light in the cable well and the possibility of water and sludge inside, there are safety risks for operators to go down the well for survey. In addition, operators must ventilate the cable well for at least 20 minutes before going down the well, which increases the survey time of the cable well and affects the survey efficiency.
