In the structure, when in use, the control mechanism 9 is firstly used for controlling the motors 24 in one group of the travelling mechanisms 2 to operate, the operation of the motors 24 drives the corresponding two lower rotating shafts 21 to rotate, thereby driving the corresponding rubber wheel 23 to rotate, because the rubber wheel 23 is extruded on the cable, the friction force between the rubber wheel 23 and the cable is larger, the rubber wheel 23 moves on the cable, while the corresponding upper turning shaft 22 and the other set of travelling mechanisms 2 act as a support, therefore, the automatic detection device smoothly runs on the cable, at this time, the corresponding upper rotating shaft 22 rotates, the rotation of the upper rotating shaft 22 is detected by the rotating speed sensor 92, the running distance signal of the automatic detection device is transmitted to the controller 91 through the processing module 93, when the automatic detection device travels to the utility pole, the controller 91 controls the motor 24 to stop operating and controls the motor 24 in another set of traveling mechanism 2 to operate; or when the automatic detection device travels to the utility pole, the trigger switch 902 abuts against a cable mounting rack or an insulator on the utility pole, and the controller 91 controls the motor 24 to stop running and controls the motor 24 in another group of travelling mechanisms 2 to run;
in the process, when the detector 33 detects that the cable is damaged, the controller 91 controls the electric slider 43 to travel on the circular sliding rail and shake in the traveling process, so that the spraying liquid in the spraying box 44 is uniformly mixed, and at the moment, the pump body 45 extracts the spraying liquid in the spraying box 44 and sprays the spraying liquid to the damaged part of the cable through the nozzle 46;
in the process of walking of the automatic detection device, when the automatic detection device encounters rain and snow weather, the small-end of the funnel shovels the rain and snow on the cable, then the rain and snow fall off under the action of gravity, the rain and snow entering the inner cavity of the small-end are collected by the annular water flowing groove 501, then are discharged through the water outlet 502, and are prevented from entering the shell 1 by the blocking of the ring blocking gasket 53;
in the process of walking of the automatic detection device, a wind whistle or a windmill with a light reflection function can work to disperse birds, so that the birds are prevented from inhabiting on cables;
during the use, controller 91 still with control mechanism 9 in the control room terminal signal connection, like this when detecting the cable damage back, can pass this signal for the terminal, let the staff know the cable breakage of being qualified for the next round of competitions, the staff can find damaged position through the mark is quick this moment, and at the in-process of construction, add spraying liquid in spraying case 44, consequently only need in spraying case 44 enough 2-3 spraying the volume can, consequently marking mechanism 4 is small, can install in shell 1, the implementation has been realized.
