[0015] Compared with the prior art, the beneficial effects of this utility model are: the cable sheath insulation fault location detection probe not only realizes automatic cable transportation and overall detection of the cable exterior, but also prevents cable wear during the detection process.

[0016] (1) By setting up a lifting frame, positioning roller, driving roller, first rubber sleeve, second rubber sleeve and driving motor, when the test is performed, the cable is passed between the positioning roller and the driving roller.

Then the rotating wheel drives the threaded rod to rotate, the threaded rod pushes the lifting frame at the bottom to descend, the lifting frame drives the first detection head to descend so that it is attached to the top of the cable. Afterwards, during the movement of the cable, the detection contacts inside the arc groove at both ends can continuously detect the cable.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-4 A detection probe for locating cable sheath insulation faults includes a detection base 1, a counterweight base plate 13 fixedly connected to the bottom end of the detection base 1, a fixed cover 2 fixedly connected to the top end of the detection base 1, a lifting frame 4 provided inside the fixed cover 2, the center line of the lifting frame 4 and the center line of the fixed cover 2 being on the same vertical plane, and a drive mechanism for transporting the cable being provided inside the fixed cover 2.

[0026] The drive mechanism includes a drive roller 14. The bottom ends of both sides inside the fixed cover 2 are movably connected to the drive roller 14. One end of the fixed cover 2 is fixedly connected to the drive motor 25. The two sides inside the lifting frame 4 are movably connected to the positioning roller 9. The outside of the positioning roller 9 is fixedly connected to the first rubber sleeve 22. The outside of the drive roller 14 is fixedly connected to the second rubber sleeve 24.

[0027] The output end of the drive motor 25 passes through one end of the fixed cover 2 and is fixedly connected to the drive roller 14. The center line of the positioning roller 9 and the center line of the drive roller 14 are on the same vertical plane.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, during the inspection, the cable is passed between the positioning roller 9 and the drive roller 14. When the top inspection structure descends, it drives the positioning roller 9 to descend and make it fit against the top of the cable. Then, the drive motor 25 is started to drive the drive roller 14 to rotate. The drive roller 14 drives the external cable to move to one side. The second rubber sleeve 24 outside the drive roller 14 and the first rubber sleeve 22 outside the positioning roller 9 can increase the friction and ensure that the cable moves at a uniform speed, thus realizing the automatic transport of the cable for inspection.

[0029] Limiting grooves 3 are provided at both ends inside the fixed cover 2. A threaded rod 6 is movably connected to the top of the lifting frame 4. A threaded cylinder 7 is fixedly connected to the top of the fixed cover 2. A rotating wheel 5 is fixedly connected through the threaded rod 6 through the threaded cylinder 7. A first detection head 8 is fixedly connected inside the lifting frame 4. A second detection head 15 is fixedly connected to the top of the detection seat 1. A set of arc-shaped grooves 20 are respectively provided at the top of the second detection head 15 and the bottom of the first detection head 8. A detection contact 21 is fixedly connected inside the arc-shaped grooves 20. A connecting wire 10 is fixedly connected to one end of the bottom of the first detection head 8. A detection screen 23 is fixedly connected to one end of the detection seat 1.

[0030] The connecting line 10 passes through the second detection head 15 and extends into the interior of the detection seat 1; the limiting groove 3 is slidably connected to the lifting frame 4.

[0031] The threaded rod 6 is threadedly connected to the threaded cylinder 7, and the detection contact 21 is electrically connected to the detection screen 23;

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when inspecting the cable, the cable is placed inside the arc-shaped groove 20 at the top of the second detection head 15. Then, the rotating wheel 5 drives the threaded rod 6 to rotate, and the threaded rod 6 pushes the lifting frame 4 at the bottom to descend. The lifting frame 4 drives the first detection head 8 to descend so that it is placed against the top of the cable. During the movement of the cable, the detection contacts 21 inside the arc-shaped grooves 20 at both ends can continuously inspect the cable. After a fault point is found, a prompt is issued through the detection screen 23 to facilitate location. This enables overall inspection of the cable's exterior.

[0033] Support plates 12 are fixedly connected to both ends of the top of the counterweight base plate 13. A support cylinder 18 is movably connected to the top of one end of the support plate 12. Limiting discs 11 are movably connected to both ends of the support cylinder 18. A threaded sleeve 17 is fixedly connected to the bottom of one end of the limiting disc 11. A two-way screw 19 is movably connected to one end of the support plate 12. A knob 16 is fixedly connected through the support plate 12.

[0034] The threaded sleeve 17 is threadedly connected to the double-acting screw 19, and the limiting discs 11 on both sides of the outer side of the support cylinder 18 are symmetrically arranged.

[0035] The center line of knob 16 and the center line of bidirectional lead screw 19 are on the same horizontal plane, and the center line of support cylinder 18 and the center line of drive roller 14 are on the same vertical plane;

[0036] Specifically, such as Figure 1 and Figure 2As shown, during testing, the cable is placed on top of the support cylinders 18 on both sides. The support cylinders 18 can support the cable and prevent friction between the cable and the probe device, which would cause wear to the cable. Then, the knob 16 is rotated to drive the bidirectional lead screw 19 to rotate. The bidirectional lead screw 19 drives the limiting discs 11 at both ends to move towards the middle through the threaded sleeve 17, so that the limiting discs 11 fit against the outside of the cable and limit the cable, preventing the cable from deviating and causing wear. This achieves the goal of preventing wear to the cable during the testing process.

[0037] Working Principle: In use, when testing a cable, the cable is placed against the arc-shaped groove 20 at the top of the second detection head 15. Then, rotating the wheel 5 drives the threaded rod 6 to rotate, which in turn pushes the lifting frame 4 at the bottom to descend. The lifting frame 4 then lowers the first detection head 8 to place it against the top of the cable. During cable movement, the detection contacts 21 inside the arc-shaped grooves 20 at both ends continuously detect the cable. If a fault is detected, a warning is issued through the detection screen 23 for easy location. During testing, the cable passes between the positioning roller 9 and the drive roller 14. As the top detection structure descends, it drives the positioning roller 9 to descend and place it against the top of the cable. Then, the drive roller 14 is activated. The motor 25 drives the drive roller 14 to rotate, and the drive roller 14 drives the external cable to move to one side. The second rubber sleeve 24 outside the drive roller 14 and the first rubber sleeve 22 outside the positioning roller 9 can increase the friction and ensure that the cable moves at a constant speed. During the test, the cable is placed on the top of the support cylinders 18 on both sides. The support cylinders 18 can support the cable and prevent friction between the cable and the probe device, which would cause wear to the cable. Then, the knob 16 is rotated to drive the bidirectional lead screw 19 to rotate. The bidirectional lead screw 19 drives the limit plates 11 at both ends to move towards the middle through the threaded sleeve 17, so that the limit plates 11 fit against the outside of the cable and limit the cable, preventing the cable from deviating and causing wear.
