Description

Technical Field

[0001] The present invention relates to the technical field of icing monitoring, and in particular to a transmission line icing monitoring device. Background Art

[0002] Icing will cause a sharp increase in the weight of the conductor, which may lead to accidents such as tower collapse, wire breakage, and insulator flashover. In order to reduce the accident rate, a transmission line icing monitoring device will be installed on one side of the conductor to monitor the icing on the conductor in a timely manner, so that operators can deal with the icing on the conductor in a timely manner.

[0003] The existing transmission line ice monitoring devices mostly use pressure sensors as core components, and determine the thickness of ice by measuring the pressure changes on the conductors. However, in actual use, the entire ice monitoring device is easily affected by ice and snow, causing the pressure components on the conductors to be easily frozen on the monitoring device, which in turn causes large errors in the detection data of the pressure sensor. The existing solution uses a sealed shell to block ice and snow, but under long-term low temperature conditions, the sealing component material becomes brittle and the sealing performance decreases, causing ice and snow to penetrate into the pressure component area of ​​the monitoring device, making it impossible to ensure stable and accurate monitoring of the monitoring device. In addition, the internal parts of the monitoring device are prone to loosening when subjected to vibration, which causes errors in the monitoring device, and thus the accuracy of the monitoring device cannot be guaranteed. At the same time, the pressure component of the monitoring device slides on the main body of the monitoring device, and the monitoring The position of the conductor where the device is located is very likely to have a large amount of dust and other debris filling the outside of the pressure component, causing the sliding resistance of the pressure component to increase, thereby reducing the monitoring accuracy of the monitoring device, and after the monitoring is completed, the pressure component on the conductor cannot be restored to its original position, and manual adjustment of the position of the pressure component on the conductor is required to ensure the accuracy of the next monitoring. Existing maintenance personnel are prone to forget to adjust the pressure component after dealing with the icing, which makes the monitoring device prone to errors during subsequent use. Therefore, a transmission line icing monitoring device is designed to solve the impact of ice, snow, vibration and dust on the monitoring accuracy of the monitoring device, while avoiding forgetting to calibrate the pressure component, resulting in a decrease in the accuracy of the monitoring device, and avoiding the decrease in the accuracy of the monitoring device, which causes maintenance personnel to be unable to deal with the icing on the conductor in time, thereby reducing safety. Summary of the Invention

In addition, in the face of dust, the shielding mechanism can prevent dust from moving to the outside of the pressure plate 26, ensuring the smooth sliding of the pressure plate 26 on the monitoring column 33 and preventing the pressure plate 26 from squeezing the limit ring 27. At the same time, after the ice on the wire 13 is cleared, the relative distance between the pressure sensor 34 and the pressure plate 26 can be adjusted through the adjustment mechanism. There is no need for manual adjustment of the monitoring device. After the monitoring is completed, it can be remotely and automatically adjusted through the control system, avoiding monitoring errors caused by manual forgetting to adjust. By heating, protecting and damping the monitoring device, the detection accuracy of the monitoring mechanism is greatly guaranteed.

[0030] Furthermore, two groups of fixed half rings 2 are provided, and the two groups of fixed half rings 2 are limited on the surface of the wire 13 by the mounting plate 21. The two groups of fixed half rings 2 are tubular on the wire 13, and the mounting plate 21 limits the fixed half ring 2 by bolts. The fixed half ring 2 limits the position of the connecting tube 22 on the wire 13. Two groups of connecting tubes 22 are provided, and the two groups of connecting tubes 22 together form a trumpet shape. The fixed half ring 2 and the connecting tube 22 are fixed on the surface of the wire 13 by the mounting plate 21, so as to facilitate the limitation of the insulation tube 24, and the connecting tube 22 is used to dock with the guide tube 23.

[0031] Furthermore, the guide tube 23 is shaped like a trumpet as a whole, which makes it convenient for the wire 13 to be inserted into the inside of the insulation tube 24 through the guide tube 23, so that the insulation tube 24 is sleeved on the surface of the wire 13. The guide tube 23 and the connecting tube 22 are connected by flanges and bolts. The insulation tube 24 is limited to one side of the fixed half ring 2 through the guide tube 23 and the connecting tube 22. The insulation tube 24 is a composite material composed of epoxy resin and glass fiber, which can effectively insulate and avoid damage to the wire 13 during the heating process. While ensuring the normal use of the monitoring device, it also ensures the service life of the wire 13. An external thread is provided on the surface of the insulation tube 24, and the ring nut 25 is threadedly connected to the external thread of the insulation tube 24. The ring nut 25 is adjusted on the position of the ring nut 25 on the insulation tube 24 through the external thread of the insulation tube 24.

[0032] Furthermore, the fixed half ring 2 limits the position of the insulation tube 24 on the wire 13, and the insulation tube 24 limits the positions of the ring nut 25, pressure plate 26 and limit ring 27 on the wire 13 through external threads, and the ring nut 25 adjusts the position of the pressure plate 26 and the limit ring 27 on the wire 13 and the insulation tube 24 by rotation, and the limit ring 27 squeezes the pressure sensor 34 through the elastic force of the squeezing spring 35. The change in the position of the pressure plate 26 changes the pressure of the squeezing spring 35 on the insertion port 36. When the ice on the wire 13 increases, the wire 13 pulls the pressure plate 26 through the insulation tube 24 to squeeze the squeezing spring 35, thereby increasing the output of the pressure sensor 34. The pressure sensor 34 outputs the weight information of the ice on the wire 13 to the management system through the wireless module, so that maintenance personnel can use the management system to know which wires 13 need to remove the ice.

[0033] Furthermore, a circular hole is provided on the surface of the monitoring column 33, and a detection circular groove is provided on one side of the circular through-hole. The insulation tube 24 passes through the circular through-hole of the monitoring column 33, and the pressure sensor 34 is slidably connected to the detection circular groove of the monitoring column 33. The pressure plate 26 drives the limit ring 27 to slide on the detection circular groove of the monitoring column 33. The insertion port 36 is located on one side of the circular through-hole of the monitoring column 33, and is generally in the shape of a trumpet. The insertion port 36 facilitates the wire 13 and the insulation tube 24 to pass through the circular through-hole of the monitoring column 33. Since the fixed half ring 2 and the insulation tube 24 are limited to the wire 13, the movement of the wire 13 will drive the insulation tube 24 and the pressure plate 26 to move synchronously, and the positions of the monitoring column 33 and the pressure sensor 34 are relatively fixed, so that the pressure plate 26 squeezes the pressure sensor 34 through the squeezing spring 35.

[0034] Furthermore, a guide groove is provided on the surface of the shock absorbing block 32, and the shock absorbing block 32 slides and rises and falls on the surface of the heating block 31 through the guide groove. The shock absorbing spring 4, the telescopic damper 41 and the power supply 42 are all located on the guide groove of the shock absorbing block 32. The shock absorbing spring 4 cooperates with the telescopic damper 41 to dampen the shock absorbing block 32 and the monitoring column 33. The shock absorption can ensure the stability of the monitoring device and thus ensure the accuracy of the monitoring. A circular hole is provided on the surface of the heating block 31, and the heating column 44 is fixedly connected to the circular hole of the heating block 31. An annular cavity is provided inside the monitoring column 33, and a heating ring 46 is fixed on the annular cavity of the monitoring column 33. There are two groups of heating rings 46, which are distributed in a ring shape on both sides of the monitoring column 33. The heating ring 46 can ensure the overall temperature of the monitoring column 33, and the heating column 44 can ensure the internal temperature of the shock absorbing block 32 and the temperature at the connection between the telescopic damper 41 and the shock absorbing block 32, thereby ensuring the stability of the shock absorbing mechanism and the stability of the monitoring column 33.

[0035] Furthermore, the power supply 42 causes the heating column 44 to heat up through the first power supply line 43, and the heating column 44 heats the heating block 31. The second power supply line 45 passes through the shock-absorbing block 32 and the monitoring column 33 and is connected to the heating ring 46. The power supply 42 causes the heating ring 46 to heat up through the second power supply line 45, and the heating ring 46 heats the monitoring column 33. The input end of the power supply 42 is connected to the external power system to ensure that the power supply 42 always has power supply. The heating ring 46 ensures the temperature of the entire monitoring device area, and the insulation tube 24 can isolate the stability of the insertion port 36 on the wire 13, ensuring the stability of the monitoring device while avoiding the influence of temperature on the wire 13.

[0036] Furthermore, the shielding cloth 51 is in the shape of a trumpet, and the connecting ring 52 is sleeved on both ends of the monitoring column 33. An annular groove is provided at both ends of the connecting ring 52, and the annular groove is provided with a thread. The threaded ring 54 is threadedly connected to the annular groove of the connecting ring 52. The fixing ring 5, the shielding cloth 51, and the shielding cloth 51 shield the connection between the monitoring column 33 and the two ends of the monitoring column 33, thereby preventing dust and impurities from entering.

[0037] Furthermore, the threaded ring 54 is threadedly connected to the power supply 42 through the swivel 53. The swivel 53 limits the position of the connecting ring 52 on the surface of the monitoring column 33 through the threaded ring 54. The connecting ring 52 cooperates with the fixed ring 5 to limit the position of the shielding cloth 51. The shielding cloth 51 is made of polyvinyl chloride coated cloth. When the insulation tube 24 moves in position, the shielding cloth 51 on the insulation tube 24 will be deformed, thereby ensuring that the shielding cloth 51 can always provide shielding. The shielding cloth 51 has low temperature resistance and flexibility, and can adapt well to the movement of the insulation tube 24.

[0038] Furthermore, the servo motor 6 drives the bidirectional screw 61 to rotate through the output shaft, and the bidirectional screw 61 drives the square nut 62 to slide on the detection circular groove of the monitoring column 33 through rotation. The square nut 62 is provided with two groups, and the sliding directions are opposite. The square nut 62 drives the pressure sensor 34 to slide horizontally on the detection circular groove of the monitoring column 33 through the adjusting rod 63 during sliding. The adjusting rod 63 will be driven by the square nut 62 to rotate and drive the pressure sensor 34 to slide on the monitoring column 33, and the square nut 62 will lock the position of the square nut 62. The square nut 62 locks the position of the pressure sensor 34 inside the monitoring column 33 through the square nut 62, which facilitates the pressure sensor 34 to detect the pressure of the wire 13 inside the monitoring column 33.

[0039] Working principle: clamp the fixed half ring 2 on the surface of the wire 13, and then fix the fixed half ring 2 on the surface of the wire 13 through the mounting plate 21 with bolts, and flange the guide cylinder 23 and the connecting cylinder 22. The fixed half ring 2 limits the position of the insulation tube 24 on the surface of the wire 13 through the connecting cylinder 22 and the guide cylinder 23. At this time, the ring nut 25 is threaded on the surface of the insulation tube 24. The insulation tube 24 limits the position of the pressure plate 26 and the limit ring 27 through the ring nut 25. When ice on the wire 13 increases, the wire 13 drives the heat-insulating tube 24 to move, and the heat-insulating tube 24 drives the annular nut 25, the pressure plate 26 and the limit ring 27 to move. The pressure plate 26 squeezes the squeezing spring 35, thereby increasing the squeezing force of the squeezing spring 35 on the pressure sensor 34, thereby measuring the mass of ice on the wire 13, and the shock-absorbing spring 4 and the telescopic damper 41 achieve shock absorption on the monitoring column 33 by damping the shock-absorbing block 32, and in the process of shock absorption, the first power supply line 43 passes through the first The power supply line 43 makes the heating column 44 heat up, and the heating column 44 directs the heat to the connection end of the heating block 31 and the shock-absorbing block 32, as well as the inside of the shock-absorbing block 32, ensuring the normal operation of the shock-absorbing mechanism. At the same time, the power supply 42 heats the monitoring column 33 through the two sets of heating rings 46 of the second power supply line 45. The monitoring column 33 avoids the low temperature of the entire monitoring device, and the insulation tube 24 can insulate the monitoring column 33 on the wire 13, ensuring the service life of the wire 13, thereby ensuring the accuracy of the monitoring device, and the connecting ring 52 is sleeved on both ends of the monitoring column 33, and the rotating ring 53 is rotated at both ends of the monitoring column 33 so that the threaded ring 54 rotates on the annular groove of the connecting ring 52. The rotating ring 53 limits the position of the connecting ring 52 at both ends of the monitoring column 33 through the threaded ring 54, thereby cooperating with the fixing ring 5 to realize the limitation of the shielding cloth 51. The fixing ring 5, the shielding cloth 51, and the shielding cloth 51 shield the connection of the monitoring column 33 at both ends of the monitoring column 33, thereby preventing dust and impurities from entering.

[0040] The output shaft of the servo motor 6 drives the bidirectional screw 61 to rotate, and the bidirectional screw 61 drives the square nut 62 to slide on the detection groove of the monitoring column 33 through rotation. The square nut 62 drives the square nut 62 to move synchronously during the sliding process, and the square nut 62 drives the adjusting rod 63 to rotate during the movement.
