Description

A power grid line monitoring device and monitoring method Technical Field

[0001] This invention relates to the field of power grid line monitoring technology, and in particular to a power grid line monitoring device and monitoring method. Background Technology

[0002] Power grid line monitoring technology plays a crucial role in modern power systems, primarily used for real-time monitoring of current and temperature changes in the power grid. By installing repeaters and various sensors in the power grid, these devices can capture the operating status of the lines and transmit the data to the terminal monitoring system via the network. The application of this technology not only improves the safety and reliability of the power grid but also enables the timely detection of potential faults and anomalies, reducing the probability of accidents. With the development of the Internet of Things and big data analytics, power grid line monitoring technology continues to evolve, gradually achieving intelligence and automation.

[0003] When using general power grid line monitoring devices, especially under conditions of drastic temperature changes, the materials used in the device will expand and contract with temperature changes, resulting in gaps at the connection between the monitoring device and the power grid conductor. Such unstable connection not only affects the stability of the device, but may also cause signal attenuation during data transmission, leading to inaccurate detection results. Loose connection may also cause damage to the equipment, or even affect the normal operation of the entire monitoring system. In some extreme cases, erroneous monitoring results may lead to errors in power dispatching decisions, further causing safety hazards and failing to meet actual needs. Summary of the Invention

[0004] This invention discloses a power grid line monitoring device and method, aiming to solve the technical problem that, during the use of general power grid line monitoring devices, especially under conditions of drastic temperature changes, the materials used in the device will undergo thermal expansion and contraction, resulting in gaps at the connection between the monitoring device and the power grid conductor. This unstable connection not only affects the stability of the device, but may also cause signal attenuation during data transmission, leading to inaccurate detection results. Loose connections may also cause damage to the equipment, or even affect the normal operation of the entire monitoring system. In some extreme cases, erroneous monitoring results may lead to errors in power dispatching decisions, further causing safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power grid line monitoring device includes a mounting plate. Two main slide rails are fixedly connected to one side of the mounting plate. A main slide plate is slidably connected to one side of the main slide rails. A moving plate is fixedly connected to one side of the main slide plate. A first sliding plate and a second sliding plate are slidably connected to the other side of the mounting plate. A controller is provided on the upper surface of one end of the second sliding plate. A detection ring is fixedly connected to one end of the second sliding plate near the controller. The controller and the detection ring are electrically connected. A temperature sensor and a current sensor are provided inside the detection ring. The temperature sensor is a DS18B20 and the current sensor is a ZLCT-02. A branch conductor is provided at one end of the second sliding plate, and a main conductor is provided at the other end of the second sliding plate.

[0007] An adjustment mechanism is installed at one end of the motion plate. The adjustment mechanism is used to adjust the connection gap between the first sliding plate, the second sliding plate and the branch wire and the main wire.

[0008] An auxiliary mechanism is installed at the other end of the motion plate. The auxiliary mechanism works in conjunction with the adjustment mechanism to stabilize the position of the mounting plate.

[0009] A filling mechanism is installed at the other end of the second sliding plate. The filling mechanism is used to assist the mounting plate in being installed at different positions on the power grid.

[0010] A linkage mechanism is installed on one side of the mounting plate between the first sliding plate and the second sliding plate. The linkage mechanism is used to reduce the impact of vibration on the mounting plate.

[0011] The adjustment mechanism includes a micro motor rotatably connected to one edge of the mounting plate. One end of the output shaft of the micro motor is fixedly connected to a threaded rod, which is threadedly connected to the moving plate. A first metal strip is slidably connected to one end of the moving plate, and a second metal strip is slidably connected to one end of the moving plate near the first metal strip. A second extrusion block is rotatably connected to both ends of the first and second metal strips, respectively.

[0012] The mounting plate has a second fixed rail fixedly connected to one end surface near both sides of the first metal strip. A second slide is slidably connected to one side of the second fixed rail. A second extrusion rail is fixedly connected to one side of the second slide. A second extrusion frame is fixedly connected to the other side of the second slide. The material of the first metal strip has a high coefficient of thermal expansion, and the material of the second metal strip has a low coefficient of thermal expansion.

[0013] The auxiliary mechanism includes a fixed plate fixedly connected to the other end of the moving plate. Two rods are fixedly connected to both sides of the fixed plate. A sliding block is slidably connected to one end of each rod. A spring is sleeved between the rod and the fixed plate. A first pressing block is rotatably connected to one end of the sliding block. A first fixed rail is fixedly connected to the surface of the other end of the mounting plate near the first pressing block.

[0014] A first carriage is slidably connected to one side of the first fixed rail, a first extrusion rail is on one side of the first carriage, and a first extrusion frame is fixedly connected to the other side of the first carriage. Multiple friction grooves are provided on one end surface of the first extrusion frame and the second extrusion frame. Two extrusion grooves are provided on one side of the second extrusion rail and the first extrusion rail respectively. The first extrusion frame and the second extrusion frame are made of insulating material.

[0015] In a preferred embodiment, the filling mechanism includes a sliding rod rotatably connected to the other end of the first sliding plate and the second sliding plate, respectively. One end of the sliding rod is respectively a first filling column and a second filling column, and one end of the first filling column and the second filling column are provided with a cylindrical end.

[0016] The linkage mechanism includes racks fixedly connected to one side edge of the first sliding plate and the second sliding plate respectively. A gear is rotatably connected to one side of the mounting plate between the first sliding plate and the second sliding plate, and the gear meshes with the two racks respectively.

[0017] A monitoring method for a power grid line monitoring device includes the following steps:

[0018] S1. Preparation: The branch conductor serves as the main conductor. The controller and detection ring detect the changes in current and temperature inside the branch conductor and send the data to the terminal through the repeater and network. In different seasons and at different times of the day, during periods of drastic temperature changes, materials with high thermal expansion coefficients will change significantly, creating gaps at the connection points and causing the connection to loosen. The second metal strip has a low thermal expansion coefficient and is less affected by temperature.

[0019] S2, Adjustment: During periods when the temperature does not change drastically, the second metal strip moves to the end away from the micro motor, causing the second extrusion blocks at both ends to separate from the second extrusion rail, and gradually pressing the second extrusion blocks at both ends of the first metal strip against the second extrusion rail. The heat generated by the current inside the branch conductor increases the length of the first metal strip, making the second sliding plate and the second extrusion frame more stable in fixing the branch conductor and the main conductor.

[0020] S3. Stability: The movement of the moving plate drives the movement of multiple sliding blocks, causing the first extrusion block at one end of the sliding block to slide inside the extrusion groove on one side of the first extrusion rail. The spring force is used to extrude the sliding block and the first extrusion block, thereby driving the first carriage and the first extrusion frame to clamp the branch wire and the main line, and maintaining the position of the mounting plate on the branch wire and the main line.

[0021] S4. Vibration Reduction: When the branch conductor and the main conductor are subjected to wind, the vibration causes the first sliding plate and the second sliding plate to slide on the mounting plate. The second sliding plate drives the gear to rotate through the rack on its edge, thereby causing the first sliding plate to slide on one side. At both ends of the first sliding plate and the second sliding plate, there are a first extrusion frame and a second extrusion frame to clamp the branch conductor and the main conductor, respectively. The first sliding plate and the second sliding plate stably clamp the branch conductor and the main conductor.

[0022] S5. Multifunctional: At the connection point where the power grid needs to add branch lines, the main line serves as the main circuit and the branch line conductors serve as branch lines. When there is only one conductor in the power grid that needs to be tested, there is no main line. Only the current and temperature inside the branch line conductor need to be tested. The first filling post is inserted between the second sliding plate and the second extrusion frame, and the second filling post is inserted between the first sliding plate and the first extrusion frame, filling the gap between the second sliding plate and the second extrusion frame and between the first sliding plate and the first extrusion frame.

[0023] As can be seen from the above, the power grid line monitoring device provided by the present invention has the following technical effects.

[0024] Firstly, during periods of drastic temperature changes, materials with high coefficients of thermal expansion undergo significant changes, creating gaps at the joints and causing them to loosen. The second metal strip, with its low coefficient of thermal expansion, is less affected by temperature. By controlling the micro motor to rotate the threaded rod, the sliding plate moves the second metal strip closer to the micro motor. The second extrusion brackets at both ends of the second metal strip slide inside the extrusion grooves on one side of the second slide. Through the cooperation of the second sliding plate and the two second extrusion brackets, the branch wires and the main wire are clamped, maintaining the connection between the mounting plate and the branch wires and the main wire. This achieves the effect of maintaining a stable connection between the mounting plate and the branch wires and the main wire under conditions of drastic temperature changes.

[0025] Secondly, by causing the branch conductor and the main conductor to vibrate when blown by the wind, the vibration drives the first and second sliding plates to slide on the mounting plate. When the second sliding plate slides relative to the mounting plate, the second sliding plate drives the gear to rotate through the rack on its edge, thereby causing the first sliding plate to slide to one side. At both ends of the first and second sliding plates, there are first and second clamping frames respectively to clamp the branch conductor and the main conductor. No matter which side the first and second sliding plates slide to, the other side of the first and second sliding plates will clamp the branch conductor and the main conductor more stably, which reduces the impact of environmental wind on the branch conductor and the main conductor.

[0026] Thirdly, when there is only one conductor in the power grid that needs to be tested, there is no main conductor. Only the current and temperature inside the branch conductor need to be tested. The first filling column and the second filling column are slid separately, and then the first filling column and the second filling column are rotated so that the first filling column is inserted between the second sliding plate and the second extrusion frame, and the second filling column is inserted between the first sliding plate and the first extrusion frame, filling the gap between the second sliding plate and the second extrusion frame and between the first sliding plate and the first extrusion frame, thus meeting the effect of various different testing needs.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] The power grid line monitoring device disclosed in this invention is mainly used in general monitoring devices. Especially under conditions of drastic temperature changes, the materials used in the device will undergo thermal expansion and contraction, resulting in gaps at the connection between the monitoring device and the power grid conductor. This unstable connection not only affects the stability of the device, but may also cause signal attenuation during data transmission, leading to inaccurate detection results. Loose connections may also cause damage to the equipment, or even affect the normal operation of the entire monitoring system. In some extreme cases, erroneous monitoring results may lead to errors in power dispatching decisions, further triggering scenarios with potential safety hazards.

[0038] Referring to Figures 1-8, a power grid line monitoring device includes a mounting plate 1. Two main slide rails 13 are fixedly connected to one side of the mounting plate 1. A main slide plate 14 is slidably connected to one side of the main slide rails 13. A moving plate 15 is fixedly connected to one side of the main slide plate 14. A first sliding plate 3 and a second sliding plate 4 are slidably connected to the other side of the mounting plate 1. A controller 5 is provided on the upper surface of one end of the second sliding plate 4. A detection ring 6 is fixedly connected to one end of the second sliding plate 4 near the controller 5. The controller 5 and the detection ring 6 are electrically connected. A temperature sensor and a current sensor are provided inside the detection ring 6. The temperature sensor is a DS18B20 and the current sensor is a ZLCT-02. A branch conductor 2 is provided at one end of the second sliding plate 4, and a main conductor 9 is provided at the other end of the second sliding plate 4.

[0039] An adjustment mechanism is installed at one end of the motion plate 15. The adjustment mechanism is used to adjust the connection gap between the first sliding plate 3, the second sliding plate 4 and the branch wire 2 and the main wire 9.

[0040] An auxiliary mechanism is installed at the other end of the motion plate 15. The auxiliary mechanism works with the adjustment mechanism to stabilize the position of the mounting plate 1.

[0041] A filling mechanism is installed at the other end of the second sliding plate 4. The filling mechanism is used to assist the mounting plate 1 in being installed at different positions on the power grid.

[0042] A linkage mechanism is installed on one side of the mounting plate 1 between the first sliding plate 3 and the second sliding plate 4. The linkage mechanism is used to reduce the impact of vibration on the mounting plate 1.

[0043] The adjustment mechanism includes a micro motor 10 rotatably connected to one edge of the mounting plate 1. One end of the output shaft of the micro motor 10 is fixedly connected to a threaded rod 34, which is threadedly connected to the moving plate 15. A first metal strip 27 is slidably connected to one end of the moving plate 15. A second metal strip 33 is slidably connected to one end of the moving plate 15 near the first metal strip 27. A second pressing block 28 is rotatably connected to both ends of the first metal strip 27 and the second metal strip 33, respectively.

[0044] A second fixed rail 32 is fixedly connected to one end surface of the mounting plate 1 near both sides of the first metal strip 27. A second slide 29 is slidably connected to one side of the second fixed rail 32. A second extrusion rail 31 is fixedly connected to one side of the second slide 29. A second extrusion frame 30 is fixedly connected to the other side of the second slide 29. The material of the first metal strip 27 has a high coefficient of thermal expansion, while the material of the second metal strip 33 has a low coefficient of thermal expansion.

[0045] The auxiliary mechanism includes a fixed plate 18 fixedly connected to the other end of the motion plate 15. Two insert rods 20 are fixedly connected to both sides of the fixed plate 18. A sliding block 21 is slidably connected to one end of the insert rod 20. A spring 19 is sleeved between the insert rod 20 and the fixed plate 18. A first pressing block 22 is rotatably connected to one end of the sliding block 21. A first fixed rail 26 is fixedly connected to the surface of the other end of the mounting plate 1 near the first pressing block 22.

[0046] A first slide 24 is slidably connected to one side of the first fixed rail 26. A first extrusion rail 23 is connected to one side of the first slide 24. A first extrusion frame 25 is fixedly connected to the other side of the first slide 24. Multiple friction grooves 36 are provided on one end surface of the first extrusion frame 25 and the second extrusion frame 30. Two extrusion grooves 35 are provided on one side of the second extrusion rail 31 and the first extrusion rail 23 respectively. The first extrusion frame 25 and the second extrusion frame 30 are made of insulating material.

[0047] In this embodiment, the branch conductor 2 serves as a branch of the main conductor 9. The controller 5 and the detection ring 6 detect the changes in current and temperature inside the branch conductor 2 and send the data to the terminal through the repeater and network. In different seasons and at different times of the day, during periods of drastic temperature changes, materials with high thermal expansion coefficients will change significantly, creating gaps at the connection points and causing the connection to loosen. The second metal strip 33 has a low thermal expansion coefficient and is less affected by temperature.

[0048] Furthermore, the micro motor 10 is controlled to drive the threaded rod 34 to rotate, causing the moving plate 15 to move the second metal strip 33 towards the end closer to the micro motor 10. The second extrusion blocks 28 at both ends of the second metal strip 33 slide inside the extrusion groove 35 on one side of the second slide 29, respectively, and extrude the second extrusion rail 31 to drive the second slide 29 and the second extrusion frame 30 to slide. The second sliding plate 4 and the two second extrusion frames 30 cooperate to clamp the branch wire 2 and the main wire 9, maintaining the connection between the mounting plate 1 and the branch wire 2 and the main wire 9.

[0049] Furthermore, it needs to be explained that during periods when temperature changes are not drastic, the micro motor 10 is similarly controlled to move the motion plate 15 and the first metal strip 27 away from the micro motor 10. Due to the design of the extrusion groove 35, the second metal strip 33 moves away from the micro motor 10, causing the second extrusion blocks 28 at both ends to separate from the second extrusion rail 31. This gradually presses the second extrusion blocks 28 at both ends of the first metal strip 27 against the second extrusion rail 31. The high thermal expansion coefficient of the first metal strip 27 increases the length of the first metal strip 27 when detecting changes in the internal current of the branch conductor 2. This makes the second sliding plate 4 and the second extrusion frame 30 more stable in fixing the branch conductor 2 and the main conductor 9, thus maintaining a stable connection between the mounting plate 1 and the branch conductor 2 and the main conductor 9 under conditions of drastic temperature changes.

[0050] In this embodiment, during the process of the micro motor 10 controlling the movement of the first metal strip 27 and the second metal strip 33, there is a period when the connection between the mounting plate 1 and the branch wire 2 and the main wire 9 is unstable. The movement of the moving plate 15 drives the movement of multiple sliding blocks 21, causing the first pressing block 22 at one end of the sliding block 21 to slide inside the pressing groove 35 on one side of the first pressing rail 23. The elastic force of the spring 19 presses the sliding block 21 and the first pressing block 22, thereby driving the first slide 24 and the first pressing frame 25 to clamp the branch wire 2 and the main wire 9, maintaining the position of the mounting plate 1 on the branch wire 2 and the main wire 9, thus stabilizing the position of the mounting plate 1 on the branch wire 2 and the main wire 9.

[0051] Referring to Figures 1, 3, 4 and 5, in a preferred embodiment, the filling mechanism includes a sliding rod rotatably connected to the other end of the first sliding plate 3 and the second sliding plate 4, respectively. One end of the sliding rod is respectively a first filling column 7 and a second filling column 8, and one end of the first filling column 7 and the second filling column 8 is provided with a cylindrical end.

[0052] The linkage mechanism includes racks 17 that are fixedly connected to one side edge of the first sliding plate 3 and the second sliding plate 4 respectively. A gear 16 is rotatably connected to one side of the mounting plate 1 between the first sliding plate 3 and the second sliding plate 4. The gear 16 meshes with the two racks 17 respectively.

[0053] In this embodiment, when the branch conductor 2 and the main conductor 9 are vibrated by the wind, the vibration causes the first sliding plate 3 and the second sliding plate 4 to slide on the mounting plate 1. When the second sliding plate 4 slides relative to the mounting plate 1, the second sliding plate 4 drives the gear 16 to rotate through the rack 17 on its edge, thereby causing the first sliding plate 3 to slide to one side. At both ends of the first sliding plate 3 and the second sliding plate 4, there are a first pressing frame 25 and a second pressing frame 30 respectively to clamp the branch conductor 2 and the main conductor 9. No matter which side the first sliding plate 3 and the second sliding plate 4 slide to, the other side of the first sliding plate 3 and the second sliding plate 4 will clamp the branch conductor 2 and the main conductor 9 more stably, which has the effect of reducing the impact of the ambient wind on the branch conductor 2 and the main conductor 9.

[0054] Furthermore, at the connection point where the power grid needs to add a branch, the main conductor 9 serves as the main circuit, and the branch conductor 2 serves as the branch. When there is only one conductor in the power grid that needs to be tested, the main conductor 9 is not required. Only the current and temperature inside the branch conductor 2 need to be tested. The first filling column 7 and the second filling column 8 are slid and then rotated so that the first filling column 7 is inserted between the second sliding plate 4 and the second extrusion frame 30, and the second filling column 8 is inserted between the first sliding plate 3 and the first extrusion frame 25. This fills the gap between the second sliding plate 4 and the second extrusion frame 30 and between the first sliding plate 3 and the first extrusion frame 25, thus meeting various testing requirements.

[0055] The other end surface of the mounting plate 1 is provided with multiple mounting holes 11.

[0056] Multiple mounting slots 12 are provided on the other end surface of the mounting plate 1 near the mounting hole 11.

[0057] It is also necessary to explain that the mounting holes 11 and mounting slots 12 are used to fix the mounting plate 1.

[0058] A monitoring method for a power grid line monitoring device includes the following steps:

[0059] S1. Preparation: Branch conductor 2 serves as a branch of the main conductor 9. The controller 5 and detection ring 6 detect the changes in current and temperature inside the branch conductor 2 and send the data to the terminal through the repeater and network. In different seasons and at different times of the day, during periods of drastic temperature changes, materials with high thermal expansion coefficients will change significantly, creating gaps at the connection points and causing the connection to loosen. The second metal strip 33 has a low thermal expansion coefficient and is less affected by temperature.

[0060] S2, Adjustment: During periods when the temperature does not change drastically, the second metal strip 33 moves away from the micro motor 10, causing the second extrusion blocks 28 at both ends to separate from the second extrusion rail 31, and gradually pressing the second extrusion blocks 28 at both ends of the first metal strip 27 against the second extrusion rail 31. The heat generated by the current inside the branch wire 2 increases the length of the first metal strip 27, making the second sliding plate 4 and the second extrusion frame 30 more stable in fixing the branch wire 2 and the main wire 9.

[0061] S3. Stability: The movement of the moving plate 15 drives the movement of multiple sliding blocks 21, causing the first pressing block 22 at one end of the sliding block 21 to slide inside the pressing groove 35 on one side of the first pressing rail 23. The spring force of the spring 19 presses the sliding block 21 and the first pressing block 22, thereby driving the first slide 24 and the first pressing frame 25 to clamp the branch wire 2 and the main wire 9, maintaining the position of the mounting plate 1 on the branch wire 2 and the main wire 9.

[0062] S4. Vibration Reduction: When the branch conductor 2 and the main conductor 9 are subjected to wind, the vibration causes the first sliding plate 3 and the second sliding plate 4 to slide on the mounting plate 1. The second sliding plate 4 drives the gear 16 to rotate through the rack 17 on its edge, thereby causing the first sliding plate 3 to slide on one side. The first pressing frame 25 and the second pressing frame 30 are respectively located at both ends of the first sliding plate 3 and the second sliding plate 4 to clamp the branch conductor 2 and the main conductor 9. The first sliding plate 3 and the second sliding plate 4 stably clamp the branch conductor 2 and the main conductor 9.

[0063] S5. Multifunctional: At the connection point where the power grid needs to add a branch, the main conductor 9 serves as the main circuit and the branch conductor 2 serves as the branch. When there is only one conductor in the power grid that needs to be tested, the main conductor 9 is not needed. Only the current and temperature inside the branch conductor 2 need to be tested. The first filling column 7 is inserted between the second sliding plate 4 and the second extrusion frame 30, and the second filling column 8 is inserted between the first sliding plate 3 and the first extrusion frame 25, filling the gap between the second sliding plate 4 and the second extrusion frame 30 and between the first sliding plate 3 and the first extrusion frame 25.

[0064] Working principle: During use, branch conductor 2 serves as a branch of the main conductor 9. The controller 5 and detection ring 6 detect the changes in current and temperature inside branch conductor 2, and transmit the data to the terminal through repeaters and networks. In different seasons and at different times of day, during periods of drastic temperature changes, materials with high thermal expansion coefficients will change significantly, creating gaps at the joints and causing loosening. The second metal strip 33 has a low thermal expansion coefficient and is less affected by temperature. The micro motor 10 drives the threaded rod 34 to rotate, causing the moving plate 15 to move the second metal strip 33 towards the end closer to the micro motor 10. The second extrusion blocks 28 at both ends of the second metal strip 33 slide inside the extrusion grooves 35 on one side of the second carriage 29, respectively, extruding the second metal strip 33. The extrusion rail 31 drives the second slide 29 and the second extrusion frame 30 to slide. The second sliding plate 4 and the two second extrusion frames 30 cooperate to clamp the branch wire 2 and the main guide wire 9, maintaining the connection between the mounting plate 1 and the branch wire 2 and the main guide wire 9. During periods of infrequent temperature changes, the micro motor 10 is similarly controlled to drive the moving plate 15 and the first metal strip 27 to move away from the micro motor 10. Due to the design of the extrusion groove 35, the second metal strip 33 moves away from the micro motor 10, causing the second extrusion blocks 28 at both ends to separate from the second extrusion rail 31. This gradually presses the second extrusion blocks 28 at both ends of the first metal strip 27 against the second extrusion rail 31. The high thermal expansion coefficient of the first metal strip 27, when detecting changes in the internal current of the branch wire 2, ensures that the branch wire... The heat generated by the current inside the conductor 2 increases the length of the first metal strip 27, making the second sliding plate 4 and the second extrusion frame 30 more stable in fixing the branch conductor 2 and the main conductor 9. This achieves the effect of maintaining a stable connection between the mounting plate 1 and the branch conductor 2 and the main conductor 9 under conditions of drastic temperature changes. During the movement of the first metal strip 27 and the second metal strip 33 controlled by the micro motor 10, there are periods when the connection between the mounting plate 1 and the branch conductor 2 and the main conductor 9 is unstable. The movement of the moving plate 15 drives the movement of multiple sliding blocks 21, causing the first extrusion block 22 at one end of the sliding block 21 to slide inside the extrusion groove 35 on one side of the first extrusion rail 23. The elastic force of the spring 19 extrudes the sliding block 21 and the first extrusion block 22, thereby driving the first slide frame 2. The first extrusion frame 25 clamps the branch wire 2 and the main wire 9, maintaining the position of the mounting plate 1 on the branch wire 2 and the main wire 9, thus stabilizing the position of the mounting plate 1 on the branch wire 2 and the main wire 9. When the branch wire 2 and the main wire 9 are vibrated by wind, the vibration causes the first sliding plate 3 and the second sliding plate 4 to slide on the mounting plate 1. When the second sliding plate 4 slides relative to the mounting plate 1, the second sliding plate 4 drives the gear 16 to rotate through the rack 17 on its edge, thereby causing the first sliding plate 3 to slide to the other side. The first extrusion frame 25 and the second extrusion frame 30 are respectively clamped at both ends of the first sliding plate 3 and the second sliding plate 4 to clamp the branch wire 2 and the main wire 9. Regardless of which side the first sliding plate 3 and the second sliding plate 4 slide to,The first sliding plate 3 and the second sliding plate 4 will more stably clamp the branch conductor 2 and the main conductor 9 on their other sides, which reduces the impact of ambient wind on the branch conductor 2 and the main conductor 9. Where the power grid needs to add branch connections, the main conductor 9 serves as the main circuit, and the branch conductor 2 serves as the branch. When only one conductor in the power grid needs to be tested, the main conductor 9 is not required; only the current and temperature inside the branch conductor 2 need to be tested. The first filling column 7 and the second filling column 8 are slid and rotated respectively, so that the first filling column 7 is inserted between the second sliding plate 4 and the second extrusion frame 30, and the second filling column 8 is inserted between the first sliding plate 3 and the first extrusion frame 25, filling the gap between the second sliding plate 4 and the second extrusion frame 30 and between the first sliding plate 3 and the first extrusion frame 25, thus meeting various testing needs.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. The monitoring method of the power grid line monitoring device according to claim 7, characterized in that, Includes the following steps: S1. Preparation: The branch conductor (2) serves as a branch of the main conductor (9). The controller (5) and the detection ring (6) detect the changes in current and temperature inside the branch conductor (2). The data is sent to the terminal through the repeater and the network. In different seasons and at different times of the day, during periods of drastic temperature changes, materials with high thermal expansion coefficients will change significantly, creating gaps at the connection points and causing the connection to loosen. The second metal strip (33) has a low thermal expansion coefficient and is less affected by temperature. S2. Adjustment: During periods of infrequent temperature changes, the second metal strip (33) moves away from the micro motor (10) to separate the second extrusion blocks (28) at both ends from the second extrusion rail (31). The second extrusion blocks (28) at both ends of the first metal strip (27) are gradually pressed against the second extrusion rail (31). The heat generated by the current inside the branch conductor (2) increases the length of the first metal strip (27), making the second sliding plate (4) and the second extrusion frame (30) more stable in fixing the branch conductor (2) and the main line (9); S3, Stability: The movement of the moving plate (15) drives the movement of multiple sliding blocks (21), causing the first extrusion block (22) at one end of the sliding block (21) to slide inside the extrusion groove (35) on one side of the first extrusion rail (23). The elastic force of the spring (19) is used to extrude the sliding block (21) and the first extrusion block (22), thereby driving the first slide frame (24) and the first extrusion. The frame (25) clamps the branch conductor (2) and the main conductor (9), maintaining the position of the mounting plate (1) on the branch conductor (2) and the main conductor (9); S4, vibration reduction: When the branch conductor (2) and the main conductor (9) are blown by the wind, the vibration causes the first sliding plate (3) and the second sliding plate (4) to slide on the mounting plate (1). The second sliding plate (4) drives the gear (16) to rotate through the rack (17) on its edge, thereby causing the first sliding plate (3) to slide on one side. At both ends of the first sliding plate (3) and the second sliding plate (4), there are a first pressing frame (25) and a second pressing frame (30) clamping the branch conductor (2) and the main conductor (9), respectively. The moving plate (4) stably clamps the branch conductor (2) and the main conductor (9); S5, multi-functional: at the connection point where the power grid needs to add a branch, the main conductor (9) serves as the main circuit and the branch conductor (2) serves as the branch. When there is only one conductor in the power grid that needs to be tested, the main conductor (9) does not exist in this case. It is only necessary to test the current and temperature inside the branch conductor (2). The first filling column (7) is inserted between the second sliding plate (4) and the second extrusion frame (30), and the second filling column (8) is inserted between the first sliding plate (3) and the first extrusion frame (25), filling the gap between the second sliding plate (4) and the second extrusion frame (30) and between the first sliding plate (3) and the first extrusion frame (25).
