Description

Technical Field

[0002] ‌Location detection of cable line faults can timely discover and accurately determine the fault location, so as to quickly repair the fault and ensure the safe and stable operation of the cable line. ‌Through fault location, greater losses caused by the expansion of the fault can be avoided, and the normal operation of the cable line can be guaranteed.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: A cable line fault locating device, comprising a locating device body, the locating device body comprising a driving mechanism 1, a front end clamping assembly 2, a locating mechanism 3 and a rear end clamping assembly 5, the surface of the front end clamping assembly 2 is integrally formed with a front end frame 10, the top of the front end frame 10 is integrally formed with a rotating sleeve 11, the top of the driving mechanism 1 passes through the inside of the rotating sleeve 11, a transmission channel 15 is welded to one side of the front end frame 10, the rear end of the transmission channel 15 is welded and fixed to the surface of the locating mechanism 3, a rotating collar 29 is provided in the middle of the locating mechanism 3, a leakage detection module 4 is inserted into the inner side of the rotating collar 29, and a current detection unit and a wireless transmission unit are screwed on the inner wall of the rotating collar 29, the two sides of the rotating collar 29 are respectively clamped with a front end plate 27 and a rear end plate 26, the cable to be tested passes through the middle position of the locating mechanism 3, and the bottom end of the leakage detection module 4 is pressed on the surface of the cable to be tested. The cable line fault locating device is used to detect whether there is leakage on the surface of the cable to be tested, and also detects and locates cracks or damage on the surface of the cable to be tested.

[0029] When the present invention is used, the cable to be tested is passed through the middle position of the positioning device, and then the front driving mechanism 1 can be started, and the front clamping component 2, the rear clamping component 5 and the middle positioning mechanism 3 are driven to move by the driving mechanism 1. Since the clamping components at both ends and the driving mechanism 1 provide a clamping effect on the cable to be tested, the positioning mechanism 3 in the middle of the linkage can also be moved along the surface of the cable to be tested, and during the movement, the leakage detection module 4 on the inner side of the positioning mechanism 3 is always pressed on the surface of the cable to be tested, and the detection rod 35 is used as a conductive probe to detect the surface of the cable to be tested, and the current detection unit installed inside the positioning mechanism 3 is used to detect whether there is current passing through the detection rod 35. In this process, the entire positioning mechanism 3 is also controlled to rotate in real time with the help of the transmission channel 15 and the internal transmission structure, so the leakage detection module 4 can be controlled to rotate and move along the cable to be tested, and the crack problem is detected during the movement. The current detection unit and the wireless transmission unit are both existing mature technologies and do not belong to the protection scope of the present invention, so their internal structure and principle are not described here.

[0030] In this embodiment, the surface of the rear-end clamping assembly 5 is integrally formed with a rear-end frame 6, and elastic push rods 7 are welded to the inner sides of the front-end frame 10 and the rear-end frame 6, and balls 8 are embedded at the ends of the elastic push rods 7. Each of the elastic push rods 7 is pressed against the surface of the cable to be tested through the balls 8. A rear-end support rod 9 is welded to the side of the rear-end frame 6, and the rear-end clamping assembly 5 is fixedly connected to the surface of the rear-end plate 26 through the rear-end support rod 9. A front-end support rod 21 is welded to one side of the front-end frame 10, and the front-end clamping assembly 2 is fixedly connected to the surface of the front-end plate 27 through the front-end support rod 21.

[0031] Specifically, when the cable to be tested is inserted, the front-end clamping assembly 2 and the rear-end clamping assembly 5 both lean against the surface of the cable to be tested through the elastic push rod 7 and the ball 8 at the end, and provide a leaning effect in multiple directions, so that the entire process can move along the surface of the cable to be tested, and also ensure that the cable to be tested can pass through the middle position of the positioning mechanism 3. After completing the sleeve installation of the cable to be tested in this state, the front-end driving mechanism 1 can be started, and each clamping assembly can be pulled to move by the driving mechanism 1, so as to achieve the purpose of detecting leakage problems and crack problems in the subsequent movement process.

[0032] In this embodiment, the driving mechanism 1 includes a driving clamp wheel 13, a rear driven clamp wheel 16 and a front driven clamp wheel 18. The two ends of the driving clamp wheel 13 are sleeved with a rotating arm 12, and the side of the rotating arm 12 is screwed with a motor 14. The two ends of the rear driven clamp wheel 16 and the front driven clamp wheel 18 are sleeved with a connecting plate 17, and the transmission channel 15 is integrally formed at the end of the connecting plate 17. One end of the rear driven clamp wheel 16 is keyed to a driving gear 22, and a toothed belt 23 is sleeved on the side of the driving gear 22. The other end of the transmission channel 15 is embedded with a driven gear 24 through a bearing, and the other end of the toothed belt 23 is sleeved on the surface of the driven gear 24. A linkage gear 25 is integrally formed on the side of the driven gear 24, and a docking frame 19 is integrally formed at the end of the transmission channel 15. The bottom of the rotating arm 12 is connected with a tension spring 20, the other end of which is connected to the surface of the front frame 10, the driving clamping wheel 13 is arranged in the upper area between the front driven clamping wheel 18 and the rear driven clamping wheel 16, and the transmission channel 15 is tilted as a whole. The front clamping assembly 2 and the rear clamping assembly 5 are installed on the surface of the cable to be tested, and the driving mechanism 1 can drive the entire detection and positioning device to move along the cable, and then automatically move along the cable to be tested for detection and processing. The device is more flexible, and a single device can detect and process a long cable line, reducing the equipment cost.

[0033] Specifically, during driving, since the driving clamping wheel 13 is connected to the rotating arm 12 at the top, after the cable to be tested passes through the driving clamping wheel 13 and the two driven clamping wheels at the bottom, the rotating arm 12 at the top will drive the driving clamping wheel 13 at the end to press downward due to the retraction action of the tension spring 20, and then squeeze the cable to be tested downward from the top. At this time, the motor 14 at the end is started, and the driving clamping wheel 13 can be driven to rotate by the motor 14, and then the driving clamping wheel 13 cooperates with the two driven clamping wheels at the bottom to drive the entire positioning device to move along the surface of the cable to be tested, thereby achieving the effect of changing the detection area.

[0034] In this embodiment, the positioning mechanism 3 includes a front plate 27, a rear plate 26 and a rotating collar 29, the front plate 27 and the rear plate 26 are connected by a middle support rod 28, a toothed ring 30 is arranged on the side of the rotating collar 29, and a notch 31 is provided on the surface of the front plate 27. The docking frame 19 is welded to the surface of the front plate 27, the edge of the linkage gear 25 passes through the notch 31 and meshes with the surface of the toothed ring 30, holes are provided in the middle of the front plate 27, the rear plate 26 and the rotating collar 29, bearings are sleeved at both ends of the middle support rod 28, and the side of the rotating collar 29 fits with the surface of each middle support rod 28. In the process of moving along the cable to be tested by the driving mechanism 1, the transmission structure of the side can control the positioning mechanism 3 to rotate continuously, so the inner leakage detection module 4 can also detect and process the side and bottom of the cable to be tested at the same time, further expanding the detection range of the cable, and the accuracy of fault detection is higher.

[0035] Specifically, after the entire positioning device is driven to move by the driving mechanism 1, since the rear end driven clamping wheel 16 at the bottom will also rotate along the surface of the cable to be tested, the rear end driven clamping wheel 16 can drive the driving gear 22 at one end to rotate, and the driving gear 22 cooperates with the toothed belt 23 to drive the driven gear 24 and the linkage gear 25 at the other end to rotate, and the linkage gear 25 passes outward from the inside of the notch 31 and meshes with the toothed ring 30 on the side of the rotating ring 29, so the linkage gear 25 can control the entire rotating ring 29 to rotate, and the rotating sleeve 11 is entirely stuck on the inner side of multiple middle support rods 28, and the front end plate 27 and the rear end plate 26 at both ends are fixed to the clamping components at both ends by the front end support rod 21 and the rear end support rod 9 respectively, so they can only rotate through the rotating ring 29.

[0036] In this embodiment, the leakage detection module 4 includes a pressing plate 37 and a detection rod 35. The top of the pressing plate 37 is inserted with a first spring rod 33. The top of the first spring rod 33 is sleeved with a middle lifting sleeve 32. The top of the detection rod 35 is integrally formed with a second spring rod 36. The top of the second spring rod 36 is sleeved with a side lifting sleeve 34. The middle lifting sleeve 32 and the side lifting sleeve 34 are both welded to the inner wall of the rotating ring 29. The bottom of the pressing plate 37 is pressed on the surface of the cable to be tested, and a guide hole 38 is opened on the surface of the pressing plate 37. The detection rod 35 passes downward from the inside of the guide hole 38. During the movement process, the detection rod 35 structure that can be lifted and lowered in the leakage detection module 4 is always pressed against the surface of the cable to be tested, so that the entire leakage detection module 4 can be stuck when it moves to the position where cracks appear on the cable surface, and then the problem of damage to the cable surface but not causing leakage can be detected, which plays a role in preventing leakage.

[0037] Specifically, the bottom pressure plate 37 is pressed downward onto the surface of the cable to be tested by the first spring rod 33, and the second spring rod 36 on the top is pulled by the pressure plate 37 to press the bottom detection rod 35 downward, so that the bottoms of the two detection rods 35 can always be pressed against the surface of the cable to be tested, so as to detect whether the surface of the cable to be tested has leakage. When cracks appear on the surface of the cable to be tested and the detection rod 35 moves to the crack area at the bottom, it will be stuck in the crack due to the action of the second spring rod 36. At this time, the leakage detection module 4 cannot continue to rotate, so the rotating ring 29 drives the positioning mechanism 3 to be in a static state, and the entire positioning device cannot move, thereby achieving the purpose of detecting the position where the crack appears.

[0038] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
