Description

Technical Field

[0001] The present invention relates to the technical field of cable detection equipment, and in particular to a wire and cable transmission component fault detection device and a method for using the same. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. In a broad sense, wires and cables are also referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: a collection of the following parts: one or more insulated wire cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors;

[0003] When performing fault detection on a cable, it is necessary to connect the detection equipment to the cable through a signal connecting line and send a pulse signal to the cable to achieve the purpose of detection. When detecting underground cables and connecting the signal connecting line to the cable through a clamp, the distance between the cable and the signal connecting line and the ground is low, and the tension of the connecting line is relatively loose during detection, which may easily cause the connector of the connecting line to come into contact with the soil on the ground during detection. This may easily cause the pulse signal transmitted by the signal line to be affected by the ground, resulting in a deviation in its propagation path and transmission to the ground, affecting the accuracy of the detection.

[0023] The present invention has the following beneficial effects:

[0024] When the plurality of long rods are rotated, the plurality of long rods will rotate to the outside of the main body, and then when the plurality of long rods are rotating, the sliding plates on the long rods will be pushed by the pushing plates to slide on the surfaces of the plurality of long rods, and when the sliding plates slide, the sliding ring 1 will be driven to slide forward synchronously, and when the sliding ring 1 slides, it will drive the two drag chains to rotate on the gear shaft and drive the sliding ring 2 to slide in the direction of the sliding ring 1. When the sliding ring 2 slides, it will pull the fixed ring through the two long plates 2, and when the fixed ring is pulled by the two long plates 2, it will squeeze the curved tube. At the same time, when the fixed ring slides, it will push the rotating plate 2 to rotate outward through the plurality of rotating plates. When the plurality of rotating plates 2 rotate outward, they will block the signal connecting line and the ground, thereby reducing the situation where the signal connecting line contacts the ground soil when the signal connecting line is connected to the cable for detection, thereby reducing the influence of the soil on the propagation of the pulse signal and improving the detection accuracy.

[0025] 2. According to the present invention, when the two drag chains drive the sliding ring 2 to slide, the sliding of the sliding ring 2 will pass through the long groove on the outer cylinder through the inner wall of the insertion rod and slide in the threaded groove on the outer surface of the threaded rod. When the sliding ring 2 drives the internal insertion rod to slide in the threaded groove on the outer surface of the threaded rod and drives the threaded rod to move, when the threaded rod rotates, it will drive the C-type limit frame to rotate synchronously. When the C-type limit frame rotates, it will drive the signal connection line passed through to rotate on the surface of the outer cylinder. When the C-type limit frame drives the signal connection line to rotate as the threaded rod rotates, the signal connection line will be entangled on the two outer cylinders and shortened, reducing the situation where the signal connection line is accidentally pulled and dragged during detection due to its excessive length, reducing the situation where the connection is loose and the signal is interrupted due to accidental pulling of the cable during the detection process, thereby improving the stability and reliability during detection.

[0026] When the plurality of connecting ears slide to the bottom of the arc groove, the rotating cylinder is driven to rotate. When the connecting disk is reset, it will drive the hollow shaft to reset on the surface of the signal connecting line. When the hollow shaft is reset on the surface of the connecting line, the tension spring on the sliding sleeve will push the sliding sleeve to reset. At this time, the multiple sliding balls inside the sliding sleeve will be squeezed by the inner wall of the hollow shaft and mounted on the surface of the connecting line. Then, when the connecting disk is reset, part of the connecting line will be driven to be recovered to the inside of the rotating cylinder. When the signal connecting line is accidentally pulled during the detection process, the part of the connecting line recovered inside the rotating cylinder can slide outward when pulled, thereby effectively reducing the cable breakage or damage due to excessive pulling. At the same time, when the length of the connecting line needs to be adjusted, the recovered part of the connecting line can be easily pulled out to adjust the length of the connecting line, which reduces damage caused by accidental pulling and improves the flexibility and practicality of the device.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] A method for using a wire and cable transmission component fault detection device, the wire and cable transmission component fault detection device, the method comprising the following steps:

[0056] S1: Signal line connection: First, open the baffle 102, then the staff rotates several long rods 202, and then passes the signal connection line through the sliding sleeve 704, the arc groove 305, the C-shaped limit frame 303, the sliding plate 205 and the fixed plate 204, and connects the passed end to the main body 1;

[0057] S2: Start the device: Then connect the other end of the signal connection line to the cable to be tested, and then start the main body 1. When the main body 1 is working, it will generate a pulse signal and flow through the signal connection line inside the cable to be tested;

[0058] S3: Signal detection: When the pulse signal encounters a fault point in the cable, it will return to the main body 1 to achieve the purpose of detection.

[0059] When in use, first open the baffle 102, then the staff rotates several long rods 202, and then passes the signal connection line through the sliding sleeve 704, the arc groove 305, the C-shaped limit frame 303, the sliding plate 205 and the fixed plate 204, and connects the passed end to the main body 1, and then connects the other end of the signal connection line to the cable to be tested, and then starts the main body 1. When working, the main body 1 will generate a pulse signal and flow through the signal connection line inside the cable to be tested. When the pulse signal encounters a fault point in the cable, it will return to the main body 1 to achieve the purpose of detection. Figure 9 As shown in .

[0060] When the staff rotates the multiple long rods 202, the rotation of the multiple long rods 202 will rotate to the outside of the main body 1. Then, when the multiple long rods 202 are rotating, the sliding disk 205 on the long rods 202 will be pushed by the pushing plate 206 to slide on the surface of the multiple long rods 202. When the sliding disk 205 slides, it will drive the sliding ring 1 401 to slide forward synchronously. When the sliding ring 1 401 slides, it will drive the two drag chains 402 to rotate on the gear shaft 403 and drive the sliding ring 2 405 to slide in the direction of the sliding ring 1 401. When the sliding ring 2 405 slides, When the fixing ring 501 is pulled by the two long plates 2 404, the curved tube 502 is squeezed by the two long plates 2 404. At the same time, when the fixing ring 501 slides, the rotating plate 2 504 is pushed to rotate outward through the multiple rotating plates 503. When the multiple rotating plates 2 504 rotate outward, they block the signal connection line and the ground, thereby reducing the contact between the signal connection line and the ground soil when the signal connection line is tested with the cable connection, thereby reducing the influence of the soil on the propagation of the pulse signal and improving the accuracy of the detection.

[0061] When the two drag chains 402 drive the sliding ring 2 405 to slide, the sliding of the sliding ring 2 405 will pass through the long groove on the outer cylinder 304 through the inner wall of the insertion rod and slide in the threaded groove on the outer surface of the threaded rod 302. When the sliding ring 2 405 drives the internal insertion rod to slide in the threaded groove on the outer surface of the threaded rod 302 and drives the threaded rod 302 to move, when the threaded rod 302 rotates, it will drive the C-type limit frame 303 to rotate synchronously. When the C-type limit frame 303 rotates, it will drive the signal connection line passed through to rotate on the surface of the outer cylinder 304. When the C-type limit frame 303 drives the signal connection line to rotate as the threaded rod 302 rotates, the signal connection line will be entangled on the two outer cylinders 304 and shortened, reducing the situation where the signal connection line is accidentally pulled and tugged during detection due to its excessive length, reducing the situation where the connection is loose and the signal is interrupted due to accidental pulling of the cable during the detection process, thereby improving the stability and reliability during detection.

[0062] When the long plate 2 404 drives the fixed ring 501 to slide, the sliding of the fixed ring 501 will push the multiple curved tubes 502 to slide. When the multiple curved tubes 502 are pushed by the fixed ring 501, they will drive the connecting ears 601 to slide inside the arc groove 305. When the multiple connecting ears 601 slide, they will drive the rotating cylinder 602 to rotate. When the rotating cylinder 602 rotates, the annular serrated groove 603 opened on its inner wall will push the L rod 604 to slide inside the annular serrated groove 603. It should be noted that the annular serrated groove 603 rotates with the rotating cylinder 602. When the shaft 702 is in motion, the arc-shaped path force portion on the annular serrated groove 603 pushes the multiple L rods 604 to slide forward. When the multiple L rods 604 slide, they push the connecting plate 701 to slide synchronously. When the connecting plate 701 slides, the multiple spring telescopic rods 703 are stretched. Then, when the connecting plate 701 slides, the hollow shaft 702 and the sliding sleeve 704 are driven to slide synchronously. At this time, the connecting line pushes the sliding sleeve 704 inside the hollow shaft 702 when the hollow shaft 702 slides. At this time, the multiple sliding balls inside the sliding sleeve 704 are separated from the inner wall of the hollow shaft 702. Then, when the multiple connecting ears 6 When 01 slides to the bottom of the arc groove 305, it will drive the rotating cylinder 602 to rotate and make the part of the path between the annular serrated groove 603 inside it correspond to the L rod 604. At this time, the multiple stretched spring telescopic rods 703 will drive the connecting disk 701 to reset. When the connecting disk 701 is reset, it will drive the hollow shaft 702 to reset on the surface of the signal connecting line. When the hollow shaft 702 is reset on the surface of the connecting line, the tension spring on the sliding sleeve 704 will push the sliding sleeve 704 to reset. At this time, the multiple sliding balls inside the sliding sleeve 704 will be squeezed by the inner wall of the hollow shaft 702. The surface of the connecting wire is supported, and then when the connecting disk 701 is reset, part of the connecting wire will be driven to be recovered into the inside of the rotating cylinder 602. When the signal connecting wire is accidentally pulled during the detection process, the part of the connecting wire recovered inside the rotating cylinder 602 can slide outward when pulled, thereby effectively reducing the cable from breaking or being damaged due to excessive pulling. At the same time, when the length of the connecting wire needs to be adjusted, the part of the connecting wire that is recovered can be easily pulled out to adjust the length of the connecting wire, thereby reducing damage caused by accidental pulling and improving the flexibility and practicality of the device.
