Description

Technical Field

[0001] This invention relates to the field of power transmission line monitoring technology, and in particular to a remote online monitoring device and method for ultra-high voltage power transmission lines. Background Technology

[0002] Online monitoring and fault diagnosis technology for power transmission lines is an emerging interdisciplinary technology. It is one of the foundations and prerequisites for condition monitoring, condition inspection, and condition maintenance. Through online monitoring, various status information can be extracted without affecting equipment operation. The monitoring center can then determine the operating status of the equipment and provide timely early warning information. Online monitoring of power transmission line faults plays a crucial role in the safe operation of the power grid.

[0003] In existing technologies, control boxes are typically installed on power towers, and then online monitoring devices are fixed to the control boxes with screws. This design has inherent limitations that significantly restrict the monitoring perspective and make it difficult to capture multi-directional status information of transmission lines, thus affecting the comprehensiveness and accuracy of the monitoring data.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a remote online monitoring device and method for ultra-high voltage transmission lines to overcome the shortcomings in current practical applications. Summary of the Invention

[0005] The purpose of this invention is to provide a remote online monitoring device and method for ultra-high voltage transmission lines, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A remote online monitoring device for ultra-high voltage transmission lines includes a base plate. An annular groove is formed at the upper end of the base plate. Two outer shells are rotatably connected to the inner wall of the annular groove. Each outer shell has a first groove, and the inner wall of each first groove has a second groove. A first arc-shaped sliding plate is slidably connected between the inner walls of the two second grooves. A third receiving groove is formed in the middle of the first arc-shaped sliding plate. The upper end of the base plate has a first receiving groove, and a first motor is fixedly connected to the bottom end of the first receiving groove. Two symmetrically distributed support plates abut against the inner wall of the first groove. A connecting plate is fixedly connected, and the connecting plate is fixedly connected to the drive end of the first motor. One of the support plates has a flat groove on its outer wall, and a second motor is fixedly connected to the flat groove. The drive end of the second motor is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the support plate. A support frame is fixedly sleeved on the outer wall of the rotating shaft. A fixing block is fixedly connected to the support frame, and the outer wall of the fixing block is fixedly connected to the inner wall of the third receiving groove. A second receiving groove is opened at the upper end of the fixing block, and a monitoring device is fixedly connected to the inner wall of the second receiving groove. The outer wall of the outer shell is also provided with an anti-accumulation component.

[0008] In a further technical solution, the cross-section of the outer shell is an inverted U-shape, and the top of the outer shell, the first sliding groove, the first arc-shaped sliding plate, and the second sliding groove are all concentric, with the center of the circle on the axis of rotation.

[0009] A further technical solution is that when the fixing block is in a vertical state, the arc-shaped distance between the third receiving groove and the inner wall of the first sliding groove is equal to the arc-shaped distance between the inner wall of the first sliding groove and the end of the first arc-shaped sliding plate, and this distance is smaller than the arc-shaped distance between the end of the first arc-shaped sliding plate and the upper surface of the bottom plate.

[0010] A further technical solution is to provide a limiting groove on the inner wall of the first receiving groove, and to fix limiting blocks to the outer wall of the support plate, wherein the limiting blocks are slidably connected to the inner wall of the limiting groove.

[0011] In a further technical solution, the anti-stacking component includes a fixing ring, a C-shaped rod, and a V-shaped rod; a fixing ring is fixedly sleeved on the outer wall of the outer shell, a C-shaped rod is fixedly connected to the fixing ring, and a V-shaped rod is fixedly connected between adjacent C-shaped rods.

[0012] In a further technical solution, the outer end of the C-shaped rod is located on the outside of the base plate.

[0013] Furthermore, the present invention also provides a method for remote online monitoring of ultra-high voltage transmission lines, based on the aforementioned remote online monitoring device for ultra-high voltage transmission lines, specifically including the following steps:

[0014] S1: The first motor drives the connecting plate to move, and then the connecting plate drives the support plate to rotate around the axis of the first receiving groove;

[0015] S2: The support plate drives the support frame to rotate;

[0016] S3: The support frame drives the fixed block to rotate around the axis of the first receiving groove, the fixed block drives the monitoring device to rotate around the axis of the first receiving groove, and the fixed block simultaneously drives the outer shell to rotate around the axis of the first receiving groove through the first arc-shaped sliding plate;

[0017] S4: The outer casing drives the fixed ring to rotate, and then the fixed ring drives the C-shaped rod and V-shaped rod to move;

[0018] S5: The second motor drives the rotating shaft to rotate, and then the rotating shaft drives the support frame to rotate around the axis of the rotating shaft. After that, the support frame drives the fixed block to rotate around the axis of the rotating shaft.

[0019] S6: The fixed block drives the monitoring device to move, and the fixed block simultaneously drives the first arc-shaped slide plate to slide along the inner wall of the second slide groove.

[0020] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0021] 1. The first motor drives the connecting plate to move, and then the connecting plate drives the support plate to rotate around the axis of the first receiving groove. Subsequently, the support plate drives the support frame to rotate, and then the support frame drives the fixed block to rotate around the axis of the first receiving groove. The second motor drives the rotating shaft to rotate, and the rotating shaft drives the support frame to rotate around the axis of the rotating shaft. Subsequently, the support frame drives the fixed block to rotate around the axis of the rotating shaft, and the fixed block drives the monitoring device to move. This allows the monitoring angle of the monitoring device to be adjusted from multiple angles, thereby enabling the capture of information about the transmission line from multiple angles, which in turn helps to improve the comprehensiveness and accuracy of the monitoring data.

[0022] 2. By covering the first slide groove with the first arc-shaped sliding plate, when the fixed block is in a vertical state, the arc distance between the third receiving groove and the inner wall of the first slide groove is equal to the arc distance between the inner wall of the first slide groove and the end of the first arc-shaped sliding plate, and this distance is smaller than the arc distance between the end of the first arc-shaped sliding plate and the upper surface of the bottom plate. This ensures that the first arc-shaped sliding plate can always cover the first slide groove when sliding along the inner wall of the second slide groove, thereby preventing birds from entering the shell through the first slide groove, thus preventing birds from affecting the operation of the first motor, support plate, rotating shaft, second motor or support frame, and ensuring that the support frame can drive the monitoring device to adjust the angle normally through the fixed block.

[0023] 3. The outer shell drives the fixed ring to rotate, and then the fixed ring pushes the wood on which the birds build their nests away from the device through the C-shaped rod and V-shaped rod, thereby preventing the birds from building their nests along the outer wall of the outer shell, and thus preventing the birds from building their nests on the outer wall of the outer shell from interfering with or hindering the monitoring process of the monitoring device.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] like Figures 1-5As shown, this embodiment of the invention provides a remote online monitoring device for ultra-high voltage transmission lines, including a base plate 1. An annular groove 2 is formed at the upper end of the base plate 1. Two outer shells 3 are rotatably connected to the inner wall of the annular groove 2. Each outer shell 3 has a first groove 4, and the inner wall of each first groove 4 has a second groove 5. A first arc-shaped sliding plate 6 is slidably connected between the inner walls of the two second grooves 5. A third receiving groove 19 is formed in the middle of the first arc-shaped sliding plate 6. A first receiving groove 7 is formed at the upper end of the base plate 1. A first motor 9 is fixedly connected to the bottom end of the first receiving groove 7. Two symmetrically distributed support plates 10 abut against the inner wall of the first groove 4. A connecting plate 12 is fixedly connected between the two support plates 10. 12 is fixedly connected to the drive end of the first motor 9. One of the support plates 10 has a flat groove 21 on its outer wall. A second motor 14 is fixedly connected to the flat groove 21. A rotating shaft 13 is fixedly connected to the drive end of the second motor 14. The rotating shaft 13 is rotatably connected to the support plate 10. A support frame 15 is fixedly sleeved on the outer wall of the rotating shaft 13. A fixing block 16 is fixedly connected to the support frame 15. The outer wall of the fixing block 16 is fixedly connected to the inner wall of the third receiving groove 19. A second receiving groove 17 is opened at the upper end of the fixing block 16. A monitoring device 18 is fixedly connected to the inner wall of the second receiving groove 17. The outer wall of the outer shell 3 is also provided with an anti-accumulation component 20, which is used to prevent birds from building nests along the outer wall of the outer shell 3.

[0034] Furthermore, such as Figure 2 As shown, the cross-section of the outer shell 3 is an inverted U-shape. The top of the outer shell 3, the first sliding groove 4, the first arc-shaped sliding plate 6, and the second sliding groove 5 are all concentric, and the center of the circle is on the axis of the rotating shaft 13.

[0035] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown, when the fixing block 16 is in a vertical state, the arc distance between the third receiving groove 19 and the inner wall of the first sliding groove 4 is equal to the arc distance between the inner wall of the first sliding groove 4 and the end of the first arc-shaped sliding plate 6, and this distance is smaller than the arc distance between the end of the first arc-shaped sliding plate 6 and the upper surface of the bottom plate 1, so that the first arc-shaped sliding plate 6 can always cover the first sliding groove 4 when it slides along the inner wall of the second sliding groove 5.

[0036] Furthermore, a limiting groove 8 is formed on the inner wall of the first receiving groove 7, and a limiting block 11 is fixedly connected to the outer wall of the support plate 10. The limiting block 11 is slidably connected to the inner wall of the limiting groove 8. The support plate 10 can only slide along the inner wall of the first receiving groove 7 by means of the cooperation of the limiting groove 8 and the limiting block 11.

[0037] Furthermore, the limiting block 11 and the corresponding limiting block 11 are an integral structure.

[0038] like Figure 1 As shown, the anti-stacking assembly 20 includes a fixing ring 201, a C-shaped rod 202, and a V-shaped rod 203; the fixing ring 201 is fixedly sleeved on the outer wall of the outer shell 3, and the C-shaped rod 202 is fixedly connected to the fixing ring 201, and a V-shaped rod 203 is fixedly connected between adjacent C-shaped rods 202.

[0039] Furthermore, the outer end of the C-shaped rod 202 is located outside the base plate 1, thereby pushing the wood for birds to build nests away from the device, thus preventing birds from building nests along the outer wall of the shell 3.

[0040] In practical application, the outer shell 3 rotates, and then the outer shell 3 drives the fixing ring 201 to rotate. After that, the fixing ring 201 pushes the wood on which the birds build their nests away from the device through the C-shaped rod 202 and the V-shaped rod 203.

[0041] In this embodiment of the invention, the first motor 9 drives the connecting plate 12 to move, then the connecting plate 12 drives the support plate 10 to rotate around the axis of the first receiving groove 7. Subsequently, the support plate 10 drives the support frame 15 to rotate, and then the support frame 15 drives the fixing block 16 to rotate around the axis of the first receiving groove 7. The second motor 14 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the support frame 15 to rotate around the axis of the rotating shaft 13. Subsequently, the support frame 15 drives the fixing block 16 to rotate around the axis of the rotating shaft 13. The fixing block 16 drives the monitoring device 18 to move, thereby allowing the monitoring angle of the monitoring device 18 to be adjusted from multiple angles, thus enabling the capture of transmission line information from multiple angles, which helps to improve the comprehensiveness and accuracy of monitoring data. The first arc-shaped sliding plate 6 covers the first sliding groove 4. When the fixing block 16 is in a vertical state, the distance between the third receiving groove 19 and the inner wall of the first sliding groove 4 is... The arc distance is equal to the arc distance between the inner wall of the first slide groove 4 and the end of the first arc-shaped slide plate 6, and this distance is smaller than the arc distance between the end of the first arc-shaped slide plate 6 and the upper surface of the bottom plate 1. This ensures that the first arc-shaped slide plate 6 can always cover the first slide groove 4 when sliding along the inner wall of the second slide groove 5, thereby preventing birds from entering the outer shell 3 through the first slide groove 4. This prevents birds from affecting the operation of the first motor 9, support plate 10, rotating shaft 13, second motor 14, or support frame 15, and ensures that the support frame 15 can drive the monitoring device 18 to adjust its angle normally through the fixing block 16. The outer shell 3 drives the fixing ring 201 to rotate, and then the fixing ring 201 pushes the wood on which the birds build their nests away from the device through the C-shaped rod 202 and the V-shaped rod 203, thereby preventing birds from building their nests along the outer wall of the outer shell 3, and thus preventing birds from building their nests on the outer wall of the outer shell 3 and interfering with or obstructing the monitoring process of the monitoring device 18.

[0042] Furthermore, the present invention also provides a method for remote online monitoring of ultra-high voltage transmission lines, based on the aforementioned remote online monitoring device for ultra-high voltage transmission lines, specifically including the following steps:

[0043] S1: The first motor 9 drives the connecting plate 12 to move, and then the connecting plate 12 drives the support plate 10 to rotate around the axis of the first receiving groove 7;

[0044] S2: The support plate 10 drives the support frame 15 to rotate;

[0045] S3: The support frame 15 drives the fixing block 16 to rotate around the axis of the first receiving groove 7, the fixing block 16 drives the monitoring device 18 to rotate around the axis of the first receiving groove 7, and the fixing block 16 simultaneously drives the outer shell 3 to rotate around the axis of the first receiving groove 7 through the first arc-shaped sliding plate 6.

[0046] S4: The outer casing 3 drives the fixed ring 201 to rotate, and then the fixed ring 201 drives the C-shaped rod 202 and the V-shaped rod 203 to move;

[0047] S5: The second motor 14 drives the rotating shaft 13 to rotate, and then the rotating shaft 13 drives the support frame 15 to rotate around the axis of the rotating shaft 13. After that, the support frame 15 drives the fixed block 16 to rotate around the axis of the rotating shaft 13.

[0048] S6: The fixed block 16 drives the monitoring device 18 to move, and the fixed block 16 simultaneously drives the first arc-shaped slide plate 6 to slide along the inner wall of the second slide groove 5.

[0049] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the software and methods.
