[0022] Please see Figure 1-4 This utility model provides a technical solution: a wire and cable tracking tester, including a main body 18, a cable support frame 10 inside the main body 18, a contaminated liquid storage tank 1 on the top of the main body 18, a delivery pipe 9 connected to one end of the storage tank 1, a delivery pump 8 on the delivery pipe 9, and a distributor frame 11 connected to the other end of the delivery pipe 9; this structure achieves automatic spraying of the contaminated liquid through the delivery pipe 9 and the delivery pump 8; the top of the cable support frame 10 has an opening, inside which are installed a limit wheel 12 and a drive wheel 15, the limit wheel 12 and the drive wheel 15 are connected. The cable support frame 10 is fixedly connected; a drive motor 14 is installed on the inner wall of the cable support frame 10, and a drive wheel 15 is connected to one end of the shaft of the drive motor 14. The drive wheel 15 is located at the bottom of the cable body 6 to be tested; this structure can drive the drive wheel 15 to rotate automatically through the drive motor 14; a drain pipe 17 is provided at the bottom of the cable support frame 10, and a control valve 16 is provided on the drain pipe 17; this structure can discharge polluted liquid in a timely manner through the drain pipe 17; the limiting wheel 12 is symmetrically distributed about the bisector of the drive wheel 15, and the top end face of the limiting wheel 12 and the drive wheel 15 form an arc structure; this structure can limit the driving wheel 15 through the limiting wheel 12. The function of the drive wheel 15 is to prevent the cable body 6 to be tested from falling off the drive wheel 15; the rotation of the drive wheel 15 can push the cable body 6 to be tested to rotate, thereby making it easier for the cable body 6 to be tested to be placed at a suitable testing angle; the cable body 6 to be tested is set on the cable support frame 10, and the first electrode frame 5 and the second electrode frame 7 are respectively set on both sides of the cable support frame 10; the inner wall of the main body 18 of the leakage current tracking test machine is provided with a longitudinal drive mechanism 2, the inner side of the longitudinal drive mechanism 2 is connected to a transverse drive mechanism 3, the bottom of the transverse drive mechanism 3 is connected to a lifting hydraulic cylinder 4, one end of the lifting hydraulic cylinder 4 is connected to a diverter frame 11, and the diverter frame 11 is U-shaped when viewed from the side. The device features a "-shaped" structure with multiple nozzles 13 evenly distributed along the inner wall of the diverter 11. This structure allows the contaminated liquid to be sprayed evenly onto the surface of the cable body 6 under test through the diverter 11 and the nozzles 13. Simultaneously, the rotation of the cable body 6 under test ensures that its outer wall is evenly sprayed. The nozzles 13 are located on the inner side of the diverter 11, which covers the outer wall of the cable body 6 under test. The longitudinal drive mechanism 2 and the transverse drive mechanism 3 of this device are both ball reciprocating screws, which can drive the lifting hydraulic cylinder 4 and the diverter 11 to adjust their positions vertically and laterally, thereby achieving automatic adjustment of the position of the diverter 11.

[0023] Working principle: When using the wire and cable leakage tracking tester, firstly, place the cable body 6 to be tested on the drive wheel 15 at the top of the cable support frame 10. Then, the drive wheel 15 rotates to push the cable body 6 to be tested to rotate to a suitable angle. Then, adjust the position of the diverter frame 11. During adjustment, the longitudinal drive mechanism 2 drives the diverter frame 11 to descend in height. Then, the transverse drive mechanism 3 drives the lifting hydraulic cylinder 4 and the diverter frame 11 to move laterally. After the diverter frame 11 is located at a suitable position on the top of the cable body 6, the lifting hydraulic cylinder 4 pushes the diverter frame 11 to cover the outer wall of the cable body 6. Then, connect the electrodes on the first electrode frame 5 and the second electrode frame 7 to the cable body 6 and then start the delivery pump 8. After the delivery pump 8 starts, the contaminated liquid inside the contaminated liquid storage tank 1 is sprayed out from the nozzle 13 through the delivery pipe 9 to spray the surface of the cable body 6 to be tested evenly.
