Description

Technical Field

[0001] This invention relates to the field of power line carrier detection technology, specifically to an online power line carrier fault detection device. Background Technology

[0002] Power line communication (PLC) is a communication method unique to power systems. It utilizes existing power lines to transmit analog or digital signals at high speed via carrier waves. Its key advantage is that it eliminates the need for new network infrastructure; data transmission can be achieved as long as there are power lines.

[0003] Since power line carrier communication transmits signals through power lines, in actual power line carrier communication systems, noise on the mains power grid and impedance changes caused by the time-varying nature of the network topology will affect power line carrier communication, as will external interference that can lead to signal weakening or even loss.

[0004] Power line carrier detection requires connection to the power line, but power lines are often continuous lines, and detection needs to be performed at the joints, which is quite troublesome. When the power line transmission line is long and has no joints, it is impossible to quickly find and troubleshoot the faulty location. The insulation of the power line needs to be cut open for detection, which is time-consuming, labor-intensive, and carries the risk of leakage. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing an online power line carrier fault detection device. Existing power line carrier detection requires connection to the power line, but power lines are often continuous, requiring detection at the joints, which is cumbersome. When the power line is long and has no joints, it is impossible to quickly locate and troubleshoot the fault, requiring the wire insulation to be cut open, which is time-consuming, labor-intensive, and carries the risk of leakage.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a power line carrier online fault detection device, including a power line carrier detection device body, a first mounting base is installed at the lower end of the power line carrier detection device body through a mounting component, and two sets of second mounting bases are installed at the rear end of the first mounting base through a spacing adjustment component. The two sets of second mounting bases are respectively located on the left and right sides of the power line carrier detection device body, and a fixing component and a wiring component are installed on the second mounting base.

[0007] The usage process includes the following steps:

[0008] Step 1: Install power line carrier detection devices at equal intervals on the power transmission lines where power line carrier communication is required;

[0009] Step 2: Connect the two terminals of the power line carrier detection device to the live wire and neutral wire of the power transmission line, respectively;

[0010] Step 3: Read the power oscilloscope waves from multiple sets of power line carrier detection devices in sequence;

[0011] Step 4: Compare the oscilloscope signals of two adjacent sets of power line carrier detection devices. If a deviation occurs, it indicates that there is a fault in the power transmission line between the two adjacent sets of power line carrier detection devices.

[0012] Step 5: Conduct troubleshooting and repair on the faulty section of the transmission line.

[0013] The beneficial effects of this invention are:

[0014] 1. By setting up multiple sets of power line carrier detection devices, and by comparing the power oscilloscopes of two adjacent sets of power line carrier detection devices, it can be determined whether there is a fault in the power line between the two adjacent sets of power line carrier detection devices, and thus the location of the fault can be quickly identified and repaired.

[0015] 2. By setting up fixing components and wiring components, when testing long, jointless power lines, the main body of the power line carrier detection device can be quickly installed together with the power line without cutting the wire insulation, which simplifies the installation and improves the practicality and applicability of the device.

[0016] Based on the above technical solution, the present invention can be further improved as follows.

[0017] Furthermore, the fixing assembly includes a mounting bracket, a mounting frame fixedly connected to the middle of the second mounting base, an upper clamping plate slidably connected to the middle of the mounting bracket, a first sliding groove that mates with the mounting bracket in the middle of the mounting bracket, a first threaded rod rotatably connected to the middle of the mounting bracket, the first threaded rod being threadedly connected to the upper clamping plate, a threaded hole that mates with the first threaded rod in the middle of the upper clamping plate, a first pulley fixedly connected to the lower end of the first threaded rod, two sets of first gears rotatably connected to the middle of the first mounting base, the two sets of first gears meshing with each other, a second pulley fixedly connected to the lower end of the first gear, the same transmission belt being fitted onto the middle of both the first pulley and the second pulley on the same side, the same protective cover rotatably connected to the outer sides of both the first pulley and the second pulley, a motor and a battery fixedly installed inside the first mounting base, a second gear fixedly installed on the output shaft of the motor, the second gear meshing with the first gear on the right side, and a lower clamping plate installed in the middle of the second mounting base.

[0018] The beneficial effect of adopting the above-mentioned further solution is that when the device needs to be installed, the two sets of upper clamping plates are first clamped onto the live wire and neutral wire of the power line respectively. By starting the motor, the output shaft of the motor rotates, which drives the second gear to rotate, thereby driving the two sets of first gears to rotate, which in turn drives the second pulley to rotate. Through the transmission belt, the first pulley and the first threaded rod rotate, thereby driving the upper clamping plates to move downward until the upper clamping plates and the lower clamping plates clamp the power line, thus quickly installing the device onto the power line.

[0019] Furthermore, a first rubber pad is bonded to the lower surface of the upper clamping plate, and a second rubber pad is bonded to the upper surface of the lower clamping plate.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the first rubber pad and the second rubber pad can further clamp the power line, which also avoids damage to the power line due to excessive clamping, and also prevents external rainwater from entering between the lower clamp and the upper clamp, causing leakage.

[0021] Furthermore, the wiring assembly includes conductive blocks. Conductive blocks are slidably connected to both ends of the middle portion of the first mounting base. A second sliding groove cooperating with the conductive blocks is opened in the middle portion of the first mounting base. A conductive arc-shaped plate is fixedly connected to the upper end of the conductive block. Multiple sets of conductive cones are fixedly connected to the inner side of the conductive arc-shaped plate. A first connecting rod is rotatably connected to the lower end of the conductive block. The upper clamping plate is slidably connected to the second mounting base. A third sliding groove cooperating with the upper clamping plate is opened in the middle portion of the second mounting base. The lower end of the first connecting rod is rotatably connected to the middle portion of the lower end of the lower clamping plate. The same conductive plate is inserted into the middle portion of the inner ends of both sets of conductive blocks. A first slot cooperating with the conductive plate is opened in the middle portion of the conductive block. A conductive rod is fixedly connected to the middle portion of the conductive plate. Two sets of detection connecting lines are installed at the lower end of the main body of the power line carrier detection device. The outer ends of the detection connecting lines are installed at the lower ends of the conductive rods.

[0022] The beneficial effect of adopting the above-mentioned further solution is that when the upper and lower clamping plates clamp the power line, the power line is located in the middle of the upper and lower clamping plates. When the upper clamping plate moves down and contacts the lower clamping plate, the upper clamping plate pushes the lower clamping plate to move downward, thereby pulling the first connecting rod to rotate. The upper end of the first connecting rod pulls the conductive block to move towards the middle of the second mounting base, thereby driving the conductive arc plate to move towards the power line until the lower clamping plate is in contact with the second mounting base. At this time, the two sets of conductive arc plates clamp the two sides of the power line, and the conductive cone pierces the outer sheath of the power line and contacts the conductive inner core of the power line, thereby guiding the power of the transmission line into the detection connection line through the conductive plate and conductive rod. This allows the main body of the power line carrier detection device to quickly connect the detection end to the power line without cutting the wire sheath, making installation quick.

[0023] Furthermore, a docking plug is fixedly installed at the outer end of the detection connection line, and a docking socket that mates with the docking plug is fixedly installed at the lower end of the conductive rod, with the docking plug inserted into the docking socket.

[0024] The advantage of adopting the above-mentioned further solution is that the main body of the power line carrier detection device can be quickly disconnected from the power line by using the docking plug and docking socket.

[0025] Furthermore, telescopic rods are fixedly connected to both the front and rear sides of the lower end of the lower clamping plate. The lower end of the telescopic rod is fixedly connected to the inner wall of the lower end of the third slide groove. A first spring is sleeved on the outer side of the telescopic rod. The upper and lower ends of the first spring abut against the lower surface of the lower clamping plate and the inner wall of the lower end of the second pulley, respectively.

[0026] The beneficial effect of adopting the above-mentioned further solution is that, through the elastic force of the first spring, the lower clamping plate is always located above the lower clamping plate when the lower clamping plate is not under force, so that the conductive arc plate is always located on both sides of the second mounting base, without affecting the power line being inserted into the middle of the lower clamping plate.

[0027] Furthermore, the spacing adjustment assembly includes a second connecting rod, the lower end of the mounting bracket is rotatably connected to the second connecting rod, the other ends of the two sets of second connecting rods are rotatably connected to the same mounting block, the middle part of the mounting block is threadedly connected to a second threaded rod, the middle part of the mounting block is provided with a threaded hole that cooperates with the second threaded rod, the front end of the second threaded rod is movably connected to the middle part of the first mounting seat through a bearing, and the rear end of the second threaded rod is fixedly connected to a knob.

[0028] The beneficial effect of adopting the above-mentioned further solution is that by rotating the second threaded rod with a knob, the mounting block can be moved forward or backward, thereby causing the second connecting rod to rotate. This allows the spacing between the two sets of second mounting seats to be adjusted, enabling the device to be installed on power lines with different spacing between live and neutral wires, thus improving the practicality and applicability of the device.

[0029] Furthermore, the mounting assembly includes a mounting head, which is fixedly connected to the lower end of the main body of the power line carrier detection device. A second slot that mates with the mounting head is provided on the rear side of the upper end of the first mounting base. The mounting head is engaged in the second slot. A sliding block is slidably connected to the upper end of the first mounting base. A fourth sliding groove that mates with the sliding block is provided on the upper end of the first mounting base. A pull rod is fixedly connected to the middle of the sliding block. The front end of the pull rod passes through the first mounting base and extends to the outside of the first mounting base. A second spring is sleeved on the outer side of the pull rod. The front and rear ends of the second spring are fixedly connected to the inner wall of the front end of the fourth sliding groove and the sliding block, respectively. A handle is fixedly connected to the front end of the pull rod. A fixing block is fixedly connected to the middle of the rear end of the sliding block. The fixing block is inserted into the middle of the mounting head. A fixing slot that mates with the fixing block is provided in the middle of the mounting head.

[0030] The beneficial effect of adopting the above-mentioned further solution is that by pulling the handle, the second spring is compressed, the sliding block moves forward in the fourth slide groove, the fixing block is pulled out from the fixing slot, and the mounting head is pulled out from the second slot. At this time, the main body of the power line carrier detection device is separated from the first mounting base, leaving the wiring part of the device on the power line, and when the main body of the power line carrier detection device is damaged, a new power line carrier detection device main body can be easily replaced.

[0042] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0043] Since power line carrier communication transmits signals through power lines, in actual power line carrier communication systems, noise on the mains power grid and impedance changes caused by the time-varying nature of the network topology can all affect power line carrier communication, as can external interference that weakens or even causes the signal to be lost.

[0044] After in-depth investigation and research into power line carrier fault detection, the inventors discovered that power line carrier detection requires connection to the power line. However, power lines are often continuous, requiring testing at the joints, which is cumbersome. When the power line is long and has no joints, it is impossible to quickly locate and troubleshoot the fault, requiring the wire insulation to be cut open for testing, which is time-consuming, labor-intensive, and carries the risk of leakage. To address these issues, the inventors proposed an online power line carrier fault detection device.

[0045] The present invention provides the following preferred embodiments.

[0046] like Figures 1-9 As shown, the power line carrier online fault detection device includes a power line carrier detection device body 1. A first mounting base 2 is installed at the lower end of the power line carrier detection device body 1 through an installation component. Two sets of second mounting bases 3 are installed at the rear end of the first mounting base 2 through a spacing adjustment component. The two sets of second mounting bases 3 are located on the left and right sides of the power line carrier detection device body 1, respectively. Fixing components and wiring components are installed on the second mounting bases 3.

[0047] The usage process includes the following steps:

[0048] Step 1: Install power line carrier detection devices at equal intervals on the power transmission lines where power line carrier communication is required;

[0049] Step 2: Connect the two terminals of the power line carrier detection device to the live wire and neutral wire of the power transmission line, respectively;

[0050] Step 3: Read the power oscilloscope waves from multiple sets of power line carrier detection devices in sequence;

[0051] Step 4: Compare the oscilloscope signals of two adjacent sets of power line carrier detection devices. If a deviation occurs, it indicates that there is a fault in the power transmission line between the two adjacent sets of power line carrier detection devices.

[0052] Step 5: Conduct troubleshooting and repair on the faulty section of the transmission line.

[0053] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the fixing assembly includes a mounting bracket 411. The mounting bracket 411 is fixedly connected to the middle of the second mounting base 3. An upper clamping plate 412 is slidably connected to the middle of the mounting bracket 411. A first sliding groove 425 that mates with the mounting bracket 411 is opened in the middle of the mounting bracket 411. A first threaded rod 413 is rotatably connected to the middle of the mounting bracket 411. The first threaded rod 413 is threadedly connected to the upper clamping plate 412. A threaded hole that mates with the first threaded rod 413 is opened in the middle of the upper clamping plate 412. A first pulley 414 is fixedly connected to the lower end of the first threaded rod 413. Two sets of first gears 415 are rotatably connected to the middle of the first mounting base 2. The two sets of first gears 415 mesh with each other. A second pulley 416 is fixedly connected to the lower end of the first gear 415. The same transmission belt 417 is fitted on the middle of both the first pulley 414 and the second pulley 416 on the same side. The first pulley 414 and the second pulley 416 are connected to each other. The outer sides of pulleys 416 are rotatably connected to the same protective cover 422. The motor 418 and battery 420 are fixedly installed inside the first mounting base 2. The output shaft of the motor 418 is fixedly installed with a second gear 419, which meshes with the first gear 415 on the right side. A lower clamping plate 421 is installed in the middle of the second mounting base 3. When the device needs to be installed, the two sets of upper clamping plates 412 are first clamped onto the live wire and neutral wire of the power line respectively. By starting the motor 418, the output shaft of the motor 418 rotates, driving the second gear 419 to rotate, thereby driving the two sets of first gears 415 to rotate, thereby driving the second pulley 416 to rotate. Through the transmission belt 417, the first pulley 414 and the first threaded rod 413 rotate, thereby driving the upper clamping plate 412 to move downward until the upper clamping plate 412 and the lower clamping plate 421 clamp the power line, thereby quickly installing the device onto the power line.

[0054] In this embodiment, as Figure 1 As shown, a first rubber pad 423 is bonded to the lower surface of the upper clamping plate 412, and a second rubber pad 424 is bonded to the upper surface of the lower clamping plate 421. The first rubber pad 423 and the second rubber pad 424 can further clamp the power line, which can also prevent the power line from being damaged due to excessive clamping, and also prevent external rainwater from entering between the lower clamping plate 421 and the upper clamping plate 412, which could lead to leakage.

[0055] In this embodiment, as Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the wiring assembly includes a conductive block 511. The conductive block 511 is slidably connected to both ends of the middle of the first mounting base 2. A second sliding groove 512, which cooperates with the conductive block 511, is opened in the middle of the first mounting base 2. A conductive arc-shaped plate 513 is fixedly connected to the upper end of the conductive block 511. Multiple sets of conductive cones 514 are fixedly connected to the inner side of the conductive arc-shaped plate 513. A first connecting rod 515 is rotatably connected to the lower end of the conductive block 511. The upper clamping plate 412 is slidably connected to the second mounting base 3. The second mounting base 3 has a third sliding groove 516 in the middle that cooperates with the upper clamping plate 412. The lower end of the first connecting rod 515 is rotatably connected to the middle of the lower end of the lower clamping plate 421. The same conductive plate 517 is inserted into the middle of the inner end of both sets of conductive blocks 511. The middle of the conductive block 511 has a first slot 518 that cooperates with the conductive plate 517. A conductive rod 519 is fixedly connected to the middle of the conductive plate 517. Two sets of detection connecting lines are installed at the lower end of the main body 1 of the power line carrier detection device. 520. The outer end of the detection connecting wire 520 is installed at the lower end of the conductive rod 519. When the upper clamping plate 412 and the lower clamping plate 421 clamp the power wire, the power wire is located in the middle of the upper clamping plate 412 and the lower clamping plate 421. When the upper clamping plate 412 moves down and contacts the lower clamping plate 421, the upper clamping plate 412 pushes the lower clamping plate 421 downward, thereby pulling the first connecting rod 515 to rotate. The upper end of the first connecting rod 515 pulls the conductive block 511 to move towards the middle of the second mounting base 3, thereby driving... The movable conductive arc plate 513 moves toward the power line until the lower clamping plate 421 is in contact with the second mounting base 3. At this time, the two sets of conductive arc plates 513 are clamped on both sides of the power line. The conductive cone 514 pierces the outer sheath of the power line and contacts the conductive inner core of the power line, thereby guiding the power of the transmission line through the conductive plate 517 and the conductive rod 519 into the detection connection line 520. This allows the main body 1 of the power line carrier detection device to quickly connect the detection end to the power line without cutting the wire sheath, making installation quick.

[0056] In this embodiment, as Figure 7 and Figure 8 As shown, a docking plug 521 is fixedly installed at the outer end of the detection connection line 520, and a docking socket 522 that cooperates with the docking plug 521 is fixedly installed at the lower end of the conductive rod 519. The docking plug 521 is inserted into the docking socket 522. By connecting the docking plug 521 and the docking socket 522, the main body 1 of the power line carrier detection device can be quickly disconnected from the power line.

[0057] In this embodiment, as Figure 6As shown, telescopic rods 523 are fixedly connected to both the front and rear sides of the lower end of the lower clamping plate 421. The lower end of the telescopic rod 523 is fixedly connected to the inner wall of the lower end of the third slide groove 516. A first spring 524 is sleeved on the outer side of the telescopic rod 523. The upper and lower ends of the first spring 524 abut against the lower surface of the lower clamping plate 421 and the inner wall of the lower end of the second pulley 416, respectively. Through the elastic force of the first spring 524, the lower clamping plate 421 is always located above the lower clamping plate 421 when the lower clamping plate 421 is not under force. Thus, the conductive arc plate 513 is always located on both sides of the second mounting base 3, without affecting the insertion of the power line into the middle of the lower clamping plate 421.

[0058] In this embodiment, as Figure 1 and Figure 2 As shown, the spacing adjustment assembly includes a second connecting rod 611. The lower end of the mounting bracket 411 is rotatably connected to the second connecting rod 611. The other ends of the two sets of second connecting rods 611 are rotatably connected to the same mounting block 612. The middle part of the mounting block 612 is threadedly connected to a second threaded rod 613. The middle part of the mounting block 612 has a threaded hole that mates with the second threaded rod 613. The front end of the second threaded rod 613 is movably connected to the middle part of the first mounting seat 2 through a bearing. The rear end of the second threaded rod 613 is fixedly connected to a knob 614. By rotating the second threaded rod 613 through the knob 614, the mounting block 612 moves forward or backward, thereby causing the second connecting rod 611 to rotate. This allows the spacing between the two sets of second mounting seats 3 to be adjusted, enabling installation on power lines with different spacing between live and neutral wires, thus improving the practicality and applicability of the device.

[0059] In this embodiment, as Figure 2 and Figure 3As shown, the mounting assembly includes a mounting head 711. The mounting head 711 is fixedly connected to the lower end of the main body 1 of the power line carrier detection device. A second slot 712 that mates with the mounting head 711 is opened on the rear side of the upper end of the first mounting base 2. The mounting head 711 is engaged in the second slot 712. A sliding block 713 is slidably connected to the upper end of the first mounting base 2. A fourth sliding groove 714 that mates with the sliding block 713 is opened on the upper end of the first mounting base 2. A pull rod 715 is fixedly connected to the middle of the sliding block 713. The front end of the pull rod 715 passes through the first mounting base 2 and extends to the outside of the first mounting base 2. A second spring 716 is sleeved on the outside of the pull rod 715. The front and rear ends of the second spring 716 are fixedly connected to the inner wall of the front end of the fourth sliding groove 714 and the sliding block 713, respectively. Next, a handle 717 is fixedly connected to the front end of the pull rod 715, and a fixing block 718 is fixedly connected to the middle of the rear end of the sliding block 713. The fixing block 718 is inserted into the middle of the mounting head 711. The middle of the mounting head 711 has a fixing slot 719 that cooperates with the fixing block 718. By pulling the handle 717, the second spring 716 is compressed, and the sliding block 713 moves forward in the fourth sliding groove 714, so that the fixing block 718 is pulled out from the fixing slot 719, and the mounting head 711 is pulled out from the second slot 712. At this time, the main body 1 of the power line carrier detection device is separated from the first mounting base 2, leaving the wiring part of the device on the power line. When the main body 1 of the power line carrier detection device is damaged, it is easy to replace it with a new power line carrier detection device 1.

[0060] It should be noted that, in this embodiment,

[0061] The specific steps for using this invention are as follows:

[0062] In use, first, rotate the second threaded rod 613 by knob 614, thereby moving the mounting block 612 forward or backward, which in turn rotates the second connecting rod 611. This allows adjustment of the distance between the two sets of second mounting seats 3 until the distance between the two sets of second mounting seats 3 is the same as the distance between the live and neutral wires on the power line. Then, engage the two upper clamps 412 on the live and neutral wires of the power line respectively. Start the motor 418, causing the output shaft of the motor 418 to rotate, which in turn drives the second gear 419 to rotate, thereby... The two sets of first gears 415 rotate, thereby driving the second pulley 416 to rotate. Through the transmission belt 417, the first pulley 414 and the first threaded rod 413 rotate, thereby driving the upper clamping plate 412 to move downward. When the upper clamping plate 412 and the lower clamping plate 421 clamp the power line, the power line is located in the middle of the upper clamping plate 412 and the lower clamping plate 421. When the upper clamping plate 412 moves downward and contacts the lower clamping plate 421, the upper clamping plate 412 pushes the lower clamping plate 421 downward, thereby pulling the first connecting rod 5. 15. Rotate the first connecting rod 515. The upper end of the first connecting rod 515 pulls the conductive block 511 to the middle of the second mounting base 3, thereby driving the conductive arc plate 513 to move towards the power line until the lower clamping plate 421 is in contact with the second mounting base 3. At this time, the two sets of conductive arc plates 513 are clamped on both sides of the power line. The conductive cone 514 pierces the outer sheath of the power line and contacts the conductive core of the power line, thereby guiding the power of the transmission line through the conductive plate 517 and the conductive rod 519 into the docking socket 522. At this time, the docking plug 521 at the end of the detection connecting line 520 on the main body 1 of the power line carrier detection device is inserted into the docking socket 522. At this time, the main body 1 of the power line carrier detection device can detect the power line carrier. Multiple sets of this device are installed on the power line in sequence, and the power oscilloscope on multiple sets of power line carrier detection devices is read in sequence. The oscilloscope signals of two adjacent sets of power line carrier detection devices are compared. When a deviation occurs, it means that there is a fault in the transmission line between the two adjacent sets of power line carrier detection devices. The faulty section of the transmission line is then investigated and repaired.

[0063] When it is necessary to remove the main body 1 of the power line carrier detection device, by pulling the handle 717, the second spring 716 is compressed, the sliding block 713 moves forward in the fourth slide groove 714, so that the fixing block 718 is pulled out from the fixing slot 719, and the mounting head 711 is pulled out from the second slot 712. At this time, the main body 1 of the power line carrier detection device is separated from the first mounting base 2.

[0064] In summary, the beneficial effects of this invention are specifically reflected in the fact that by setting up multiple sets of power line carrier detection devices, and by comparing the power oscilloscopes of two adjacent sets of power line carrier detection devices, it can be determined whether there is a fault in the power line between the two adjacent sets of power line carrier detection devices. This allows for quick identification and location of the fault for troubleshooting. Furthermore, when detecting long, jointless power lines, the main body 1 of the power line carrier detection device can be quickly installed together with the power line without cutting the wire insulation, making installation simple.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
