[0002] In order to extend the service life of cables buried underground, an insulating layer resistant to salt spray corrosion is usually provided. However, during regular inspections, the soil needs to be dug up and the cables need to be cut, and short-circuit, open-circuit and grounding tests need to be performed using a detector to assess whether the resistance value is normal (an increase in resistivity indicates corrosion). In the prior art, conductive clips (commonly known as alligator clips) are used at the terminals of the detector, but a conductive clip needs to be inserted into the soil during grounding testing. Since the existing conductive clips have a short length (≤5cm) and a large head angle (≥90°), the insertion resistance is large and the stability is poor. They are easily pulled off by the cable, affecting the detection accuracy. Summary of the invention

[0032] It also includes an auxiliary component; the auxiliary component is connected to the clamping block 6; the auxiliary component includes a fixed block 9 and a linkage unit; the fixed block 9 is slidably connected to the clamping block 6; a groove 93 is provided on the clamping block 7, and the side of the fixed block 9 away from the clamping block 6 is located on the inner side of the groove 93; a groove 94 is provided on the clamping block 7, and the groove 94 is connected to the groove 93; the fixing cylinder 5 and the clamping block 6 are jointly connected with a linkage unit.

[0034] The fixing block 9 is provided with an oblique angle, so that the fixing block 9 is easier to insert into the second groove 94 .

[0035] The rope 12 is made of a smooth material to reduce friction.

[0036] Preparation operation: manually dig out the soil layer covering the cable to expose the cable and cut the cable; detection operation: manually clamp the conductive clamp 3 on the cable so that one of the terminals of the detector 1 is electrically connected to the cable through the wire 1 2 and the conductive clamp 3, then manually hold the fixed tube 5 and drive it to move downward, the fixed tube 5 drives the clamp block 1 6 and the clamp block 2 7 to move downward, because the clamp block 1 6 and the clamp block 2 7 are in the shape of a long conical rod when they are tightened, the clamp block 1 6 and the clamp block 2 7 can be easily inserted into the soil manually, at this time, the other terminal of the detector 1 is grounded through the wire 2 4, the clamp block 1 6 and the clamp block 2 7, then the cable is manually grounded through the detector 1, when performing short circuit and open circuit detection, the conductive clamp 3 is manually clamped on one of the cables so that one of the terminals of the detector 1 is electrically connected to the cable through the wire 1 2 and the conductive clamp 3. Electrical connection, then, manually hold the fixed tube 5 and press the dial block 8 with the thumb, the dial block 8 drives the clamp block 2 7 to rotate around the torsion spring shaft thereon, so that the clamp block 1 6 and the clamp block 2 7 are fan-shaped, and then manually drive the fixed tube 5 and the parts thereon to move, so that the clamp block 1 6 and the clamp block 2 7 move to the outside of the other cable, and then stop pressing the dial block 8, the torsion spring shaft rebounds and drives the clamp block 2 7 to move back, the clamp block 1 6 and the clamp block 2 7 clamp the cable, so that the other terminal of the detector 1 is electrically connected to the cable through the wire 2 4, the clamp block 1 6 and the clamp block 2 7, and then stop manually holding the cable and the fixed tube 5, and use the detector 1 to perform short circuit and open circuit detection on the cable. When in use, the clamp block 1 6 and the clamp block 2 7 are arranged as a whole in the shape of a conical long rod, so that the clamp block 1 6 and the clamp block 2 7 can be easily inserted into the soil for grounding operation, and can be deeply inserted into the soil with strong stability.

[0037] During the detection process, after the connection terminal of the detector 1 is connected to the cable or the ground, when the cable is detected by the detector 1, the intelligent module (signal processing module and data comparison unit) in the detector 1 determines the cable status and transmits the data to the display terminal of the detector 1, so that the cable data is presented on the display terminal, and then manually judges whether the values ​​such as the resistivity of the cable are normal. If the resistivity and other values ​​of the cable deviate too much from the normal value, it indicates that the cable is faulty. At this time, the faulty position of the cable is manually broken and the cable is replaced. It should be noted that the existing detector 1 can detect the approximate location of the cable fault.

[0038] During the process of inserting the clamping block 1 6 and the clamping block 2 7 into the soil, if the soil is hard, the clamping block 2 7 will be subjected to excessive soil resistance and will tend to deviate, increasing the difficulty of insertion. In the long run, it will also damage the torsion spring shaft on the clamping block 2 7, resulting in a decrease in service life. Therefore, during the grounding operation, the sleeve 10 is manually held tightly, and the sleeve 10 and the parts thereon are driven to move downward. When the lower ends of the clamping block 1 6 and the clamping block 2 7 touch the ground, the wire 2 4, the fixing tube 5, the clamping block 1 6 and the clamping block 2 7 are blocked by the ground and remain stationary. The manual operation continues to push the sleeve The cylinder 10 moves downward, causing the sleeve 10 to slide downward on the fixed cylinder 5 and compress the spring 11. The sleeve 10 drives the upper end of the rope 12 to move downward, causing the rope 12 to pull the fixed block 9 to move upward, and stretching the short elastic rope 13, causing the fixed block 9 to move from the groove 1 93 to the inner side of the groove 2 94. At this time, the fixing block 9 and the groove 2 94 cooperate to lock the lower ends of the clamping block 1 6 and the clamping block 2 7. The sleeve 10 continues to be pushed downward manually. After the flange 1 91 of the sleeve 10 contacts the fixed cylinder 5, the sleeve 10 pushes the fixed cylinder 5 moves downward, the fixing cylinder 5 drives the clamping block 1 6 and the clamping block 2 7 to move downward, so that the clamping block 1 6 and the clamping block 2 7 are inserted into the soil to complete the grounding operation. During this process, the ends of the clamping block 1 6 and the clamping block 2 7 are locked by the fixing block 9, so as to avoid the deviation of the clamping block 2 7 and interfere with the insertion, and also protect the torsion spring shaft on the clamping block 2 7 to improve the service life. After the insertion operation is completed, the manual stop holding the sleeve 10, at this time the spring 11 rebounds and drives the sleeve 10 to move back to the original position, and the short elastic rope 13 rebounds and drives the fixing block 9 to move back to the original position The unlocking operation is completed when the sleeve 10 and the parts thereon are moved downward by manually holding the sleeve 10, so that the sleeve 10 can be linked with the fixing block 9 to lock the clamping block 1 6 and the clamping block 2 7, so that the clamping block 1 6 and the clamping block 2 7 are inserted into the soil in a locked state, which can avoid the deviation of the clamping block 2 7 and cause interference to the insertion, and can also protect the torsion spring shaft on the clamping block 2 7 to increase its service life. In addition, the manual operation only needs to perform the insertion operation normally to automatically realize the locking operation without adding operating steps, which is conducive to improving convenience.

[0039] During the grounding process, when the sleeve 10 slides downward on the fixed tube 5, the lower end of the sleeve 10 will be sleeved on the outer side of the upper end of the clamp block 2 7, thereby locking the upper ends of the clamp blocks 1 6 and 2 7 through the sleeve 10, further improving the stability of the clamp blocks 1 6 and 2 7, and avoiding the deviation of the clamp block 2 7 and causing interference to the insertion.

[0040] Example 2

[0041] On the basis of Example 1, Figure 8 As shown, it also includes a second shift block 14; the second shift block 14 is fixedly connected to the second clamping block 7, and the upper end of the second shift block 14 is inclined toward the first clamping block 6.

[0042] An image acquisition probe is provided on the top of the detector 1. After the short circuit, open circuit and grounding detection of the cable, if the resistivity and other values ​​of the cable are normal, the detector 1 is manually held and moved so that the probe on it is aimed at the cable insulation layer, and the image of the cable insulation layer is acquired through the probe. The acquired image is then analyzed by the intelligent module inside the detector 1 to determine whether the cable insulation layer is corroded. If corrosion occurs, it is manually evaluated whether to replace it based on the analyzed data.

[0043] It also includes convex strips 15; a plurality of convex strips 15 are fixedly connected to the sleeve 10 for anti-slip.

[0044] like Figure 4 As shown, during the wiring process, when the sleeve 10 is manually grasped with one hand and the thumb of this hand is used to press the shift block 18, the shift block 18 will be subjected to an oblique upward pressing force. At this time, the shift block 18 will apply an upward component of force to the clamp block 27, so that the clamp block 27 will apply an upward component of force to the clamp block 16, and the clamp block 16 applies an upward thrust to the fixed cylinder 5, and the sleeve 10 is manually grasped and remains stationary, and the fixed cylinder 5 will slide upward relative to the sleeve 10, causing the rope 12 to pull the fixed block 9 to move upward into the groove 294, locking the clamp block 27, resulting in the failure of the clamp block 27 to open. Therefore, the shift block 214 is used instead of the shift block 18. During the wiring process, the sleeve 10 is manually grasped and the thumb is used to push the shift block 14 obliquely downward. The shift block 14 drives the clamp block 27 to flip and open upward around the torsion spring rotating shaft thereon, and then the cable is clamped and connected. During the process of manually pushing the shift block 14 obliquely downward, the shift block 1 The downward force received by 4 will act on the clamping block 1 6 and the clamping block 2 7, so that the clamping block 2 7 applies a downward thrust to the fixed cylinder 5, and the sleeve 10 is manually held and kept stationary. At this time, the fixed cylinder 5 has a tendency equivalent to the downward movement of the sleeve 10, and the sleeve 10 blocks the fixed cylinder 5 through the flange 2 92, that is, the fixed cylinder 5 and the sleeve 10 will not slide relative to each other, and the fixed block 9 will not slide into the groove 2 94, so that the clamping block 2 7 can be normally opened for clamping and connecting operation. When in use, the shifting block 2 14 is used instead of the shifting block 1 8. During the wiring process, the sleeve 10 is manually held and the thumb is used to push the shifting block 2 14 downward. The shifting block 2 14 opens the clamping block 2 7 through the thrust for clamping operation. After the shifting block 2 14 applies the thrust to the fixed cylinder 5, the sleeve 10 blocks the fixed cylinder 5 through the flange 2 92, so that the fixed cylinder 5 and the sleeve 10 will not slide relative to each other, thereby avoiding the problem of the failure of the clamping block 2 7 to open.
