[0022] Please see Figures 1-4 A high-precision cable detector includes a base plate 1, with a detection mechanism 2 mounted on top of the base plate 1. The detection mechanism 2 includes a protective housing 201, with two fixed long plates 210 and two fixed rods 211 fixedly connected to the inner wall of the protective housing 201. A control device 208, a support plate 215, a drive motor 205, and two support frames 204 are fixedly connected to the upper surface of the base plate 1. A reinforcing ring 6 is fixedly connected to the outer surface of each fixed rod 211. The ends of the two reinforcing rings 6 that are far apart from each other are fixedly connected to the inner wall of the protective housing 201. The reinforcing rings 6 can reinforce the fixed rods 211 and the protective housing 201, thereby enhancing the stability of the device.

[0023] An ultrasonic flaw detector 212 is fixedly connected to one side of two fixed long plates 210 that are close to each other. A micro current measuring module 213 is fixedly connected to one end of two fixed rods 211 that are close to each other. A protective box 3 is fixedly connected to the outer surface of the drive motor 205. The bottom surface of the protective box 3 is fixedly connected to the upper surface of the base plate 1. The protective box 3 can protect the drive motor 205 and prevent it from being damaged by the outside world during use.

[0024] An alarm light 207 is fixedly connected to the upper surface of the protective housing 201. Four fixing bolts 206 are fixedly connected to the inner wall of the protective housing 201. A movable baffle 202 is snapped into the inside of the protective housing 201. A limiting plate 7 is fixedly connected to the outer surface of the support plate 215. The bottom surface of the limiting plate 7 is fixedly connected to the upper surface of the base plate 1. The limiting plate 7 can limit the position of the support plate 215, thereby fixing and limiting it to prevent its position from shifting.

[0025] A pull handle 203 is fixedly connected to the upper surface of the movable baffle 202, a limit ring 214 is fixedly connected to the upper surface of the support plate 215, a take-up roller 216 is fixedly connected to the output end of the drive motor 205, and a fixing ring 5 is fixedly connected to the outer surface of the alarm light 207. The bottom end of the fixing ring 5 is fixedly connected to the upper surface of the protective shell 201. The fixing ring 5 can fix the alarm light 207 and the protective shell 201, which has a strong reinforcement effect and avoids the problem of displacement and instability during use.

[0026] Each support frame 204 has a bearing 217 fixedly connected to its inner wall. The inner rings of the two bearings 217 are fixedly connected to the outer surface of the take-up roller 216. The outer surface of the protective shell 201 has two through holes 209. The outer surface of the pull handle 203 has two reinforcing frames 4 fixedly connected to it.

The reinforcing frames 4 can reinforce the pull handle 203 and the movable baffle 202 to prevent them from swaying during use.

[0027] The working principle of this utility model is as follows: In use, the cable to be tested is first passed through the limiting ring 214, then through the through hole 209 into the protective housing 201. Next, the movable baffle 202 is opened by pulling the handle 203, facilitating the cable's passage through the ultrasonic flaw detector 212 and the microcurrent measurement module 213. It is then fixed to the take-up roller 216. When testing is required, the movable baffle 202 is installed on the protective housing 201, and the position of the movable baffle 202 can be easily fixed using the fixing bolt 206. The limit switch is then activated by rotating the output of the drive motor 205, which in turn rotates the take-up roller 216, thereby pulling the cable to move. This allows for cable inspection, and the micro-current measurement module 213 can detect extremely small leakage currents, thus accurately assessing the quality of the cable insulation. When the cable quality is found to be unsuitable, the alarm light 207 will sound an alarm and stop the drive motor 205, effectively preventing the detection equipment from failing to inspect the cable insulation layer, which would reduce the accuracy of the inspection.
