Description

Technical Field

[0001] The present invention relates to the technical field of communication cables, and in particular to a communication cable fault monitoring device and a use method thereof. Background Art

[0002] Communication cables are a general term for various conductors that transmit electrical or optical signals. Communication cables are usually composed of a cable core, a sheath, and a protective layer.

[0003] During the use of communication cables, ground faults, short circuit faults and line break faults may occur. Comprehensive faults are faults with two or more properties at the same time. Cable faults are generally difficult to detect directly. Instruments for testing cable faults must be used to measure and determine the location of the fault.

[0004] When the communication cable is installed in a pipeline, the cable is fixed in the pipeline by a bracket to facilitate the protection of the cable. However, when a communication cable fails, it is impossible for humans to rush to the fault point in time. At the same time, the pipeline space is small, and it is difficult to detect the fault manually. It takes a lot of time to troubleshoot and repair the fault. When a comprehensive fault occurs, it is necessary to use multiple instruments to detect and troubleshoot the fault point, which makes it take a long time to restore the communication cable, and the timely repair and use of the communication cable cannot be guaranteed. Therefore, we propose a communication cable fault monitoring device and a method for using it. Summary of the invention

[0020] A method for using a communication cable fault monitoring device, wherein the state of a communication cable in a pipeline is monitored by a monitoring device in a pipeline. When an abnormality occurs in the communication cable, a driving motor drives a driving screw to rotate, so that the driving screw drives a cable fault detector to move, and the cable fault detector drives a fixed-point instrument and a probe rod to move, so as to perform fault troubleshooting. When a fault occurs, an alarm is sounded immediately.

[0021] When the driving screw drives the transmission seat to move the cable fault detector, the fixed-point instrument on the cable fault detector moves to perform ground fault and short circuit fault troubleshooting. When a fault is detected, data is recorded and uploaded. At the same time, the gear moves and rotates, driving the first rotating rod to rotate, so that the first rotating rod drives the second rotating rod to move and rotate, driving the first connecting seat connected to the end of the second rotating rod to reciprocate up and down;

[0022] When the first connecting seat moves, the positioning rod and the connecting block fixed thereto move accordingly. When the fixing rod and the second connecting seat are driven downward by the connecting block, the contact switch moves downward accordingly. When the roller moves downward and contacts the ground, the third connecting seat is pushed to move upward. At the same time, the roller contacts the ground and rolls. When the third connecting seat moves, the sliding rod is pushed to slide along the inner wall of the second connecting seat. At this time, the contact block on the third connecting seat moves toward the contact switch. When the contact block contacts the contact switch, a signal is fed back through the contact switch to control the drive motor to stop, so that the cable fault detector stops in place, and the broken wire fault is checked through the probe rod.

[0023] Feedback is given to the transmission motor through the contact switch, and the transmission motor starts to drive the first sprocket to rotate, driving the chain transmission. At this time, the chain drives the first sprocket and the second sprocket to rotate at the same time, so that the rotation of the nut seat drives the threaded rod to slide downward along the inner wall of the first connecting seat. Under the rebound of the spring, the sliding seat is pushed to move downward, driving the probe rod to move downward and contact the ground. The probe rod is used in conjunction with the cable fault detector to perform power failure detection, and the disconnection fault is checked and recorded;

[0024] After the troubleshooting is completed, at a specified time interval, the transmission motor is controlled to drive the first sprocket to rotate in the opposite direction, so that the threaded rod moves upward, pulling the sliding seat and the probe rod upward, and compressing the spring. At this time, the probe rod moves upward and separates from the ground, and the drive motor is started to drive the cable fault detector to continue moving to perform the next interval fault troubleshooting. Under the movement of the cable fault detector, the gear on the rack rotates, and the first connecting seat is driven to move upward through the movement of the first rotating rod and the second rotating rod crank connecting rod, so that the sliding seat drives the probe rod to move upward, and the probe rod is driven to move up and down reciprocatingly with the movement of the cable fault detector to perform the broken wire fault troubleshooting.

[0025] When the monitoring equipment in the cable fault detector eliminates the broken wire fault at the beginning, the transmission motor is started to drive the first sprocket and the second sprocket to rotate, so that the threaded rod moves upward.

[0027] 1. The communication cable fault monitoring device and the method of using the same are provided with a monitoring device in a pipeline. The status of the communication cable in the pipeline is monitored. When the communication cable is abnormal, the driving motor drives the driving screw to rotate, so that the driving screw drives the cable fault detector to move, and the cable fault detector drives the fixed-point instrument and the probe rod to move to perform fault detection. At the same time, when a fault occurs, an alarm is sounded immediately, and people rush to the pipeline.

When the cable fault detector is controlled to stop in place by the contact switch, the probe rod is at the lowest point, and the contact switch is used to feedback to the transmission motor, which controls the probe rod to move downward and contact the ground to troubleshoot and record the broken wire fault. After the troubleshooting is completed, at a specified time interval, the transmission motor is controlled to drive the probe rod to move upward and separate from the ground, and the drive motor is started to drive the cable fault detector to continue moving to troubleshoot the next interval.

[0041] The embodiment of the present application provides a communication cable fault monitoring device and a method for using the same, which solves the problem that when a communication cable fails, humans cannot rush to the fault point in time, and at the same time, the pipeline space is small, so it is difficult to perform fault detection manually, and it takes a lot of time to troubleshoot and repair the fault. When a comprehensive fault occurs, it is necessary to use multiple instruments to detect and troubleshoot the fault point, which makes it take a long time to restore the communication cable, and it is impossible to ensure the timely repair and use of the communication cable. The monitoring device is set in the pipeline, and the status of the communication cable in the pipeline is monitored. When the communication cable fails, Normally, the driving motor drives the driving screw 3 to rotate, so that the driving screw 3 drives the cable fault detector 1 to move, and the cable fault detector 1 drives the fixed-point instrument 101 and the probe rod 102 to move, so as to perform fault detection. At the same time, when a fault occurs, an alarm is sounded immediately, and people rush to the pipeline. When the maintenance personnel arrive at the fault site, they use the detection results of the fixed-point instrument 101 and the probe rod 102 as a reference to perform precise positioning and maintenance, thereby speeding up the maintenance speed and avoiding people from performing fault detection on the communication cables in the pipeline. Targeted maintenance can be performed, thus reducing the workload of maintenance personnel.

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The embodiment of the present invention discloses a communication cable fault monitoring device and a method for using the same. Figure 1-9 As shown, it includes a cable fault detector 1, a mounting frame 201 is fixedly installed on the outer wall of the cable fault detector 1, the mounting frame 201 is fixedly installed on the inner wall of the pipeline, one end of the mounting frame 201 is fixed with a fixing frame 2 by bolts, and the cable fault detector 1 is connected to the pipeline through the fixing frame 2 and the mounting frame 201;

[0044] A driving motor is provided on the mounting frame 201, and a driving screw rod 3 is connected to the end of the driving motor. The cable fault detector 1 is connected to the driving screw rod 3 by transmission. The cable fault detector 1 is plugged with a fixed-point instrument 101 and a probe rod 102 through a plug. A monitoring device is provided in the pipeline to monitor the status of the communication cable in the pipeline. When the communication cable is abnormal, the driving motor drives the driving screw rod 3 to rotate, so that the driving screw rod 3 drives the cable fault detector 1 to move, and the cable fault detector 1 drives the fixed-point instrument 101 and the probe rod 102 to move, and the fault is checked. At the same time, when a fault occurs, an alarm is sounded at the first time, and people rush to the pipeline. When the maintenance personnel arrive at the fault location, they refer to the detection results of the fixed-point instrument 101 and the probe rod 102 for accurate positioning and maintenance, which speeds up the maintenance speed and avoids people troubleshooting the communication cable in the pipeline. It can carry out targeted maintenance and reduce the workload of the maintenance personnel. The cable fault detector 1 is provided with:

[0045] The transmission unit includes a first rotating rod 403 and a second rotating rod 404. One end of the first rotating rod 403 is rotatably connected to the second rotating rod 404, and the other end of the second rotating rod 404 is rotatably connected to the first connecting seat 5. The transmission unit is used to drive the first connecting seat 5 to reciprocate up and down. When the cable fault detector 1 moves under the rotation of the driving screw 3, the grounding fault and short circuit fault of the communication cable are eliminated through the fixed-point instrument 101. When a disconnection fault occurs, when the cable fault detector 1 moves, the first rotating rod 403 is driven to rotate, so that the first rotating rod 403 and the second rotating rod 404 perform a crank-connecting rod motion, and the first connecting seat 5 is pushed to reciprocate;

[0046] The contact unit includes a second connection seat 6, which is connected to the first connection seat 5. A contact switch 604 is installed on the second connection seat 6. The contact unit is used to start the contact switch 604. When the first connection seat 5 reciprocates and drives the second connection seat 6 to move, the roller 603 connected to the second connection seat 6 contacts the ground, and the third connection seat 602 is pushed to move and contact the contact switch 604, and the contact switch 604 is started. At this time, the contact switch 604 controls the driving motor to stop, so that the cable fault detector 1 stops in place, and the broken wire fault is checked through the probe rod 102;

[0047] The moving unit includes a sliding seat 7 and a threaded rod 701. The bottom end surface of the threaded rod 701 is fitted with the sliding seat 7. The threaded rod 701 is slidably connected to the first connecting seat 5. The probe rod 102 is installed on the sliding seat 7. The moving unit is used to drive the sliding seat 7 and the probe rod 102 to move. When the first connecting seat 5 moves back and forth, the sliding seat 7 is driven to move back and forth, so that the probe rod 102 moves back and forth. When the cable fault detector 1 is controlled to stop in place by the contact switch 604, the probe rod 102 is at the lowest point at this time. Feedback is given to the transmission motor 8 through the contact switch 604 to control the probe rod 102 to move downward and contact the ground to perform broken line fault troubleshooting and record. After the troubleshooting is completed, at a specified time interval, the transmission motor 8 is controlled to drive the probe rod 102 to move upward and separate from the ground, and the drive motor is started to drive the cable fault detector 1 to continue moving to perform next interval fault troubleshooting.

[0048] The top end face of the cable fault detector 1 is fixedly connected with a transmission seat 401, and the transmission seat 401 is threadedly connected to the outer peripheral wall of the driving screw 3. The cable fault detector 1 is connected to the driving screw 3 through the transmission seat 401. When the driving screw 3 drives the transmission seat 401 to move the cable fault detector 1, the fixed-point instrument 101 on the cable fault detector 1 moves to check for ground faults and short circuit faults. When a fault is detected, the data is recorded and uploaded, which is convenient for maintenance personnel to directly locate and repair at the specified position according to the data, avoiding the process of manual detection in the pipeline.

[0049] The outer peripheral wall of the transmission seat 401 is rotatably connected with a gear 402, and the outer wall of the gear 402 is rotatably connected to the other end of the first rotating rod 403. The outer peripheral wall of the gear 402 is meshed with a rack 4, and the rack 4 is fixedly connected between two adjacent mounting frames 201. At the same time, under the movement of the cable fault detector 1 and the transmission seat 401, the gear 402 is driven to move. At this time, the gear 402 moves with the cable fault detector 1 and rotates under the action of the rack 4. Under the rotation of the gear 402, the first rotating rod 403 is driven to rotate, so that the first rotating rod 403 drives the second rotating rod 404 to move and rotate, and drives the first connecting seat 5 connected to the end of the second rotating rod 404 to move up and down.

[0050] A connecting frame 103 is fixedly connected to the outer wall of the cable fault detector 1, and the inner wall of the connecting frame 103 is fixedly connected to the fixed-point instrument 101 by bolts. A guide rod 502 is fixedly connected to the bottom end face of the connecting frame 103, and a fixed seat 501 is slidably connected to the outer wall of the guide rod 502. The fixed seat 501 is fixedly connected to the first connecting seat 5, and the first connecting seat 5 is slidably connected to the guide rod 502 through the fixed seat 501. The first connecting seat 5 slides on the guide rod 502 through the fixed seat 501, so that the movement path of the first connecting seat 5 is limited. At this time, the rotation path of the second rotating rod 404 is limited, so that the rotation of the gear 402 drives the first rotating rod 403 and the movement path of the first rotating rod 403 is limited, thereby ensuring the stability of the overall movement, making the movement of the fixed-point instrument 101 and the probe rod 102 stable, and ensuring the detection effect.

[0051] A positioning rod 503 is fixedly connected to the bottom end face of the first connecting seat 5, and the outer peripheral wall of the positioning rod 503 is slidably connected to the sliding seat 7. The end of the positioning rod 503 away from the first connecting seat 5 is fixedly connected to the connecting block 504, and the bottom of the connecting block 504 is fixedly connected to the fixing rod 601, and the end of the fixing rod 601 away from the connecting block 504 is fixedly connected to the second connecting seat 6. When the first connecting seat 5 moves, the positioning rod 503 and the connecting block 504 fixedly connected thereto move accordingly. When the fixing rod 601 and the second connecting seat 6 are driven to move downward by the connecting block 504, the contact switch 604 moves downward accordingly, and the sliding sliding seat 7 on the positioning rod 503 drives the probe rod 102 to move downward accordingly.

[0052] A sliding rod 605 is slidably connected to the inner wall of the second connecting seat 6, and the top end face of the sliding rod 605 is fixedly connected to the limiting seat 606. The limiting seat 606 fits the top end face of the second connecting seat 6, and the end of the sliding rod 605 away from the limiting seat 606 is fixedly connected to the third connecting seat 602. When the roller 603 moves downward and contacts the ground, it pushes the third connecting seat 602 to move upward. At the same time, the roller 603 contacts the ground and rolls. When the third connecting seat 602 moves, it pushes the sliding rod 605 to slide along the inner wall of the second connecting seat 6.

[0053] The bottom end face of the third connecting seat 602 is fixedly connected with a roller 603, and the top end face of the roller 603 is fixedly connected with a contact block 607, and the contact block 607 is directly below the contact switch 604. At this time, the contact block 607 on the third connecting seat 602 moves toward the contact switch 604. When the contact block 607 contacts the contact switch 604, a signal is fed back through the contact switch 604 to control the drive motor to stop, so that the cable fault detector 1 stops in place, and the broken wire fault is checked through the probe rod 102.

[0054] A transmission motor 8 is installed on the bottom end surface of the first connecting seat 5. Sensors are correspondingly provided for the transmission motor 8 and the contact switch 604. The output end of the transmission motor 8 is connected to the first sprocket 801. The outer peripheral wall of the first sprocket 801 is transmission-connected with a chain 803. The chain 803 meshes with the first sprocket 801 and the second sprocket 802, and at the same time, feedback is given to the transmission motor 8 through the contact switch 604. At this time, the transmission motor 8 starts to drive the first sprocket 801 to rotate, and drives the chain 803 to transmit. At this time, the chain 803 drives the first sprocket 801 and the second sprocket 802 to rotate at the same time, so that the nut seat 804 rotates and drives the threaded rod 701 to slide downward along the inner wall of the first connecting seat 5;

[0055] Conduct the broken wire fault investigation and record it. After the investigation is completed, at a specified time interval, control the transmission motor 8 to drive the probe rod 102 to move upward and separate from the ground, start the drive motor, and drive the cable fault detector 1 to continue moving to conduct the next interval fault investigation.

[0056] The bottom of the second sprocket 802 is fixedly connected with a nut seat 804, and the nut seat 804 is rotatably connected to the top end surface of the first connecting seat 5. The nut seat 804 is meshed with the threaded rod 701, and the outer peripheral wall of the threaded rod 701 is sleeved with a spring 702. The two ends of the spring 702 are respectively fixedly connected with the first connecting seat 5 and the sliding seat 7. When the threaded rod 701 moves downward, the sliding seat 7 is pushed downward under the rebound of the spring 702, and the probe rod 102 is driven to move downward and contact the ground, and the power failure detection is performed through the probe rod 102 in cooperation with the cable fault detector 1;

[0057] Conduct a line break fault check and record. After the check is completed, control the transmission motor 8 to drive the first sprocket 801 to rotate in the opposite direction at a specified time interval, so that the threaded rod 701 moves upward, pulls the sliding seat 7 and the probe rod 102 upward, and compresses the spring 702;

[0058] At this time, the probe rod 102 moves upward and separates from the ground, and the drive motor starts, driving the cable fault detector 1 to continue moving to perform the next section fault troubleshooting, so as to avoid the cable fault detector 1 moving and causing the probe rod 102 to contact the ground and cause damage to the probe rod 102;

[0059] When the cable fault detector 1 moves, the gear 402 on the rack 4 rotates, and the first connecting seat 5 moves upward through the crank-connecting rod movement of the first rotating rod 403 and the second rotating rod 404, so that the sliding seat 7 drives the probe rod 102 to move upward, and the probe rod 102 moves up and down with the movement of the cable fault detector 1 to perform the disconnection fault troubleshooting;

[0060] When the monitoring device in the cable fault detector 1 starts to eliminate the broken wire fault again, the transmission motor 8 is started to drive the first sprocket 801 and the second sprocket 802 to rotate, so that the threaded rod 701 moves upward. At this time, when the threaded rod 701 moves upward to the top, it contacts the sensor provided on the cable fault detector 1 to transmit signals, and cuts off the signal transmission of the contact switch 604, avoiding the start of the transmission motor 8 and the stop of the drive motor, ensuring that the cable fault detector 1 moves at a constant speed without stopping, and driving the fixed-point instrument 101 to move for ground fault and short circuit fault troubleshooting.

7. A method for using a communication cable fault monitoring device according to claim 6, characterized in that: The following steps are involved: S1: The status of the communication cable in the pipeline is monitored by the monitoring equipment in the pipeline. When the communication cable is abnormal, the driving motor drives the driving screw (3) to rotate, so that the driving screw (3) drives the cable fault detector (1) to move, and the cable fault detector (1) drives the fixed point instrument (101) and the probe rod (102) to move, so as to perform fault detection. When a fault occurs, an alarm is issued immediately; S2: When the driving screw (3) drives the transmission seat (401) to move the cable fault detector (1), the fixed point instrument (101) on the cable fault detector (1) moves to perform ground fault and short circuit fault troubleshooting. When a fault is detected, data is recorded and uploaded. At the same time, the gear (402) moves and rotates, driving the first rotating rod (403) to rotate, so that the first rotating rod (403) drives the second rotating rod (404) to move and rotate, driving the first connecting seat (5) connected to the end of the second rotating rod (404) to reciprocate up and down; S3: When the first connecting seat (5) moves, the positioning rod (503) and the connecting block (504) fixedly connected thereto move accordingly. When the fixing rod (601) and the second connecting seat (6) are driven downward by the connecting block (504), the contact switch (604) moves downward accordingly. When the roller (603) moves downward and contacts the ground, the third connecting seat (602) is pushed to move upward. At the same time, the roller (603) contacts the ground and rolls. When the third connecting seat (602) moves, the sliding rod (605) is pushed to slide along the inner wall of the second connecting seat (6). At this time, the contact block (607) on the third connecting seat (602) moves toward the contact switch (604). When the contact block (607) contacts the contact switch (604), a signal is fed back through the contact switch (604) to control the drive motor to stop, so that the cable fault detector (1) stops at the original location, and the disconnection fault is checked through the probe rod (102). S4: Feedback is given to the transmission motor (8) through the contact switch (604), and the transmission motor (8) starts to drive the first sprocket (801) to rotate, driving the chain (803) to transmit. At this time, the chain (803) drives the first sprocket (801) and the second sprocket (802) to rotate at the same time, so that the nut seat (804) rotates and drives the threaded rod (701) to slide downward along the inner wall of the first connecting seat (5). Under the rebound of the spring (702), the sliding seat (7) is pushed to move downward, driving the probe rod (102) to move downward and contact the ground. The probe rod (102) cooperates with the cable fault detector (1) to perform power failure detection, and the line break fault is checked and recorded; S5: After the troubleshooting is completed, at a specified time interval, the transmission motor (8) is controlled to drive the first sprocket (801) to rotate in the opposite direction, so that the threaded rod (701) moves upward, pulls the sliding seat (7) and the probe rod (102) upward, and compresses the spring (702). At this time, the probe rod (102) moves upward and separates from the ground, and the drive motor is started to drive the cable fault detector (1) to continue moving to perform the next interval fault troubleshooting. When the cable fault detector (1) moves, the gear (402) on the rack (4) rotates, and the first connecting seat (5) is driven to move upward through the first rotating rod (403) and the second rotating rod (404) crank connecting rod movement, so that the sliding seat (7) drives the probe rod (102) to move upward, and the probe rod (102) is driven to move up and down with the movement of the cable fault detector (1) to perform the disconnection fault troubleshooting. S6: When the monitoring device in the cable fault detector (1) starts to eliminate the broken line fault, the transmission motor (8) is started to drive the first sprocket (801) and the second sprocket (802) to rotate, so that the threaded rod (701) moves upward. At this time, when the threaded rod (701) moves upward to the top, it contacts the sensor provided on the cable fault detector (1) to transmit signals, and cuts off the signal transmission of the contact switch (604), thereby preventing the transmission motor (8) from starting and the drive motor from stopping, thereby ensuring that the cable fault detector (1) moves at a constant speed without stopping, and driving the fixed-point instrument (101) to move to detect ground faults and short circuit faults.
