Turnable cable duct inspection device

Abstract

The invention provides a turnable cable duct inspection device which comprises a driving assembly, a four-jaw chuck, two three-jaw chucks, an installation connecting assembly, walking wheel assemblies, a camera, a battery box and a controller, the driving assembly comprises four Namb wheels, four motor supports, four motors and four connecting flanges, and three sets of walking wheel assemblies are arranged on each three-jaw chuck. The installation connecting assembly comprises two connecting supports, two connecting installation pieces and two connecting pins. The two three-jaw chucks and thefour-jaw chuck are rotatably connected with one three-jaw chuck through the installation connecting assembly, the camera is fixedly arranged on the three-jaw chuck on the right side, the battery boxand the controller are arranged in the two connecting installation pieces respectively, the camera and the four motors are electrically connected with the controller respectively, and the battery boxis used for providing a working power source. When the device works, the device can automatically turn in the cable duct, is stable in operation and high in traffic capacity, and can solve the problemthat similar devices in the prior art cannot be suitable for bent cable ducts.

Description

technical field [0001] The invention relates to the technical field of distribution network cable duct inspection, in particular to a turnable cable duct inspection device. Background technique [0002] After the distribution network civil construction pipe trench is completed, the MPP pipe (power cable protection pipe, cable pipe) is buried in the pipe trench, and then the power cable is laid in the MPP pipe. Before laying power cables, it is necessary to check the conditions inside the MPP pipe. To ensure that there is no foreign matter or deformation in the MPP pipe, so that the cable can be laid smoothly. At present, the inspection of underground pre-buried MPP pipes before the laying of power cables is mainly carried out by devices similar to robots. The camera detection components including the pan / tilt on the car body, the camera on the pan / tilt, and the lighting on both sides can check the internal state of the pipeline, and its movement in the pipeline is controll...

AI Technical Summary

Problems solved by technology

At present, the common problems of similar cable duct inspection devices are: first, the device does not have the ability to automatically turn. That is, the entire inspection of the cable duct cannot be successfully completed, which greatly limits the application scenarios of such devices in the prior art; secondly, the operation in the duct is unstable and the traffic capacity is not strong
