It should be noted that the number of turns of the tape winding machine 302 is an integer, that is, the notch two 303 is always upward, so as to facilitate detachment of the following device from the cable.
The working principle of the invention is as follows: the worker overlaps the notch I11 on the main body bracket 1 with the cable through the insulating rod 102, so that the cable penetrates through the main body bracket 1, in a default state, the first semicircular wheel 42 and the second semicircular wheel 44 are overlapped, the connecting plate 47 is positioned at the blank of the other half edges of the first semicircular wheel 42 and the second semicircular wheel 44 and is attached to the second semicircular wheel 44, the stepping motor 16 is started, the stepping motor 16 drives the first semicircular wheel 42 to rotate, the second semicircular wheel 44 is fixed because of almost no resistance between the sliding groove 46 and the sliding rod 45, when the sliding rod 45 on the first semicircular wheel 42 moves from one end to the other end of the sliding groove 46 on the second semicircular wheel 44, the second semicircular wheel 44 is driven to synchronously rotate, at the moment, the second semicircular wheel 44 and the first semicircular wheel 42 form a circle, in the process, the first semicircular wheel 42 gradually compensates for the blank part of the second semicircular wheel 44, so that the connecting plate 47 is extruded under the limitation of the limiting bar 31, the connecting plate 47 drives the supporting plate 3 to horizontally move, the second sliding rail 41 on the supporting plate 3 extrudes the rotating shaft of the roller 13, the roller 13 is driven to move along the first sliding rail 12, so as to clamp a cable, after the roller 13 clamps the cable, the rotating shaft part of the roller 13 is positioned at the tail end of the second sliding rail 41, the spur gear II 65 is driven to be meshed with the spur gear I64, the semicircular wheel II 44 and the semicircular wheel I42 form a circle at the moment, the connecting plate 47 is always extruded, the continuous rotation of the stepping motor 16 can not influence the synchronous clamping mechanism 4 at the moment, the bevel gear II 63 is driven to rotate along with the continuous rotation of the output shaft of the stepping motor 16, the bevel gear II 63 is driven to rotate through the bevel gear I61 on the shaft I62, the spur gear I64 is driven to rotate through the spur gear II 65, the roller 13 is driven to move on the cable, after the first semicircular wheel 42 and the second semicircular wheel 44 are controlled by the stepping motor 16 to form a complete circle to extrude the connecting plate 47, the device can be firmly fixed on a cable even if equipment faults or bad weather occur during detection, has an automatic limiting function, and is more stable and reliable compared with an electric control;
When the cable is damaged, the voltage at the damaged position is changed by losing the grid of the insulating layer and is detected by the electromagnetic induction sensor 15, the electromagnetic induction sensor 15 is electrically connected with the micro air pump 17, the adhesive tape winding machine 302 and the air cylinder 91 which are mentioned in the following, the roller 13 continues to move forward for a small distance, so that after the damaged position of the cable is positioned between the arc covers 18, the stepping motor 16 stops working, the micro air pump 17 is started, air is injected into the space between the first piston 72 and the liquid box 2, at the moment, the air pipe 75 transmits the partial air into the air pressure cover 74, the pressure in the air pressure cover 74 is increased, the arc covers 18 are driven to clamp and wrap the cable through the second piston 77 and the push rod 76, after the arc covers 18 wrap the cable, the push rod 76 connected with the arc covers 18 limits the second piston 77 to move continuously, the first piston 72 moves along with the continuous injection of the gas into the micro air pump 17, the insulation repair liquid in the liquid box 2 is extruded, the insulation repair liquid enters the arc cover 18 through the infusion tube 83, then flows out of the liquid outlet hole 81 on the arc cover 18, repairs the broken part of the cable, after the repair is finished, the micro air pump 17 opens the negative pressure, drives the arc cover 18 to release the clamping of the cable, recovers the insulation repair liquid at the liquid outlet hole 81 part of the arc cover 18, avoids the insulation repair liquid flowing out along the arc cover 18, and when the micro air pump 17 stops working, the stepper motor 16 and the tape winding machine 302 are started, one end of the insulation tape 304 is clamped by the rubber block 92 and the air cylinder 91 in a default state, the rotation speed of the roller 13 is accurately controlled by the stepper motor 16, so that the repair effect is better when the cable is wound by the stepper motor 16, when the winding is finished, the cylinder 91 shaft body stretches out, the rubber block 92 is far away from the cylinder 91, at this moment, the insulating tape 304 is partially attached to the cylinder 91 shaft body under the action of the tape winding machine 302, then the cylinder 91 recovers the shaft body, the rubber block 92 drives the insulating tape 304 to approach the blade 94 on the cylinder 91, one end cut by the blade 94 corresponds to the notch III 93, the other end is clamped and fixed by the rubber block 92, the subsequent repair winding is facilitated, after the detection of a single cable is finished, the stepping motor 16 reversely rotates, so that the semicircular wheel I42 and the semicircular wheel II 44 are driven to overlap, after complete overlapping, the semicircular wheel I42 and the semicircular wheel II 44 synchronously act, the stepping motor 16 drives the driving shaft to rotate, so that the gap of the semicircular wheel I42 and the semicircular wheel II 44 corresponds to the connecting plate 47, at this moment, the spring 53 is restored to be driven to reset the supporting plate 3, and further the roller 13 is driven to release the limitation on the cable, and the device is removed by reusing the insulating rod 102.
