Description

Technical Field

[0001] This utility model belongs to the field of power transmission line monitoring technology, and more specifically, it relates to a power transmission line icing monitoring device. Background Technology

[0002] Power transmission lines are constructed by using transformers to step up the voltage of electricity generated by generators, which is then transmitted to the power lines via circuit breakers and other control equipment. Structurally, power transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines consist of transmission towers, conductors, insulators, line hardware, guy wires, tower foundations, and grounding devices, and are erected above the ground. Based on the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. In winter, for every 1 mm increase in ice thickness on transmission lines, their mechanical load can increase by 300-500 kg. If not cleared promptly, the ice layer, under the influence of wind, can cause the transmission lines to vibrate, leading to minor issues like hardware wear and insulator breakage, or even severe issues like line fracture and transmission tower structural collapse.

[0003] To monitor the ice thickness on power transmission lines, holes are often drilled in a certain angle steel of the transmission tower and ice sensors are installed. Because the ice thickness on power transmission lines is unevenly distributed along the vertical direction (for example, ice is more likely to accumulate below the power transmission line), if the installation height of the ice sensor is incorrect, it needs to be measured again and the hole needs to be drilled again in the angle steel for installation. The process is extremely cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] This utility model provides a transmission line icing monitoring device that enables rapid adjustment of the vertical height of the icing sensor, saving time and effort.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A transmission line icing monitoring device is provided, comprising a mounting rod, an adjusting bracket, a sliding rod, a locking component, and an icing sensor. The mounting rod is mounted on the angle steel of the transmission tower, and a control box is mounted on the mounting rod. The adjusting bracket is mounted on the mounting rod and extends outward, with a sliding sleeve extending vertically along a main shaft connected to its outer end. The sliding rod is slidably connected within the sliding sleeve, and several locking holes spaced apart along the axial direction of the sliding rod are provided on its side wall. The locking component is mounted on the sliding sleeve and is used to engage with one of the locking holes. The icing sensor is mounted on the sliding rod and electrically connected to the control box, and is used to monitor the icing thickness of the transmission line.

[0006] In one possible implementation, the locking element is disposed radially through the outer peripheral wall of the sleeve and is threadedly connected to the sleeve.

[0007] In one possible implementation, the upper end of the slide bar is connected to an upwardly extending threaded post, and a limiting nut is threaded around the outer periphery of the threaded post. The slide bar can drive the limiting nut to move downward and abut against the upper end surface of the slide sleeve to limit the axial displacement of the slide bar.

[0008] In one possible implementation, the mounting rod is provided with a lower flange that is connected to the outside of the angle steel via a first bolt assembly.

[0009] In some embodiments, a horizontally extending adjustment hole is provided through the lower wing plate. The diameter of the adjustment hole gradually increases in the extension direction of the adjustment hole, and the two ends of the adjustment hole are defined as its large diameter end and its small diameter end, respectively. The large diameter end of the adjustment hole is adapted to allow the first bolt assembly to pass through, and the small diameter end of the adjustment hole is adapted to engage with the first bolt assembly.

[0010] In some embodiments, the upper edge of the lower flange is connected to an upper flange extending above the angle steel. A first mating hole extending along the direction of the adjustment hole is provided through the upper flange. A second mating hole communicating with the first mating hole is provided through the upper flange. The second mating hole extends away from the lower flange to the side edge of the upper flange. The upper flange is connected to the angle steel by a second bolt assembly passing through the first mating hole.

[0011] Specifically, when the first bolt assembly is located within the large-diameter end of the adjusting hole, the second bolt assembly is located within the second mating hole; when the lower flange disengages from the first bolt assembly, the second bolt assembly separates from the second mating hole.

[0012] In one possible implementation, two adjustment brackets are spaced apart in the vertical direction, and each adjustment bracket is equipped with a slide bar. One slide bar is equipped with an icing sensor, and the other slide bar is equipped with a six-element miniature weather instrument that is electrically connected to the control box.

[0013] In one possible implementation, the adjusting bracket is fixed to the mounting rod by two clamping hoops that engage with the outer periphery of the mounting rod, and the two clamping hoops are connected by a fastener.

[0014] In one possible implementation, a solar panel electrically connected to a control box is mounted on the mounting rod. The solar panel is mounted on the mounting rod via a fixed bracket. The fixed bracket is provided with a main clamp and a secondary clamp that hug the outer periphery of the mounting rod. The main clamp and the secondary clamp are connected by a connector.

[0015] In some embodiments, two secondary clamps are provided at intervals along the vertical direction.

[0016] Compared with the prior art, the transmission line icing monitoring device provided in this embodiment can quickly adjust the vertical height of the icing sensor by releasing the locking member when it is necessary to adjust the vertical height of the icing sensor, sliding the slide rod up and down, and locking the locking member into the corresponding locking hole after adjustment. This saves time and effort. Attached Figure Description

Detailed Implementation

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0028] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a number" means two or more, unless otherwise explicitly specified.

[0029] Power transmission lines are constructed by using transformers to step up the voltage of electricity generated by generators, which is then transmitted to the power lines via circuit breakers and other control equipment. Structurally, power transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines consist of transmission towers, conductors, insulators, line hardware, guy wires, tower foundations, and grounding devices, and are erected above the ground. Based on the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. In winter, for every 1 mm increase in ice thickness on transmission lines, their mechanical load can increase by 300-500 kg. If not cleared promptly, the ice layer, under the influence of wind, can cause the transmission lines to vibrate, leading to minor issues like hardware wear and insulator breakage, or even severe issues like line fracture and transmission tower structural collapse.

[0030] To monitor the ice thickness on power transmission lines, holes are often drilled in a certain angle steel of the transmission tower and ice sensors are installed. Because the ice thickness on power transmission lines is unevenly distributed along the vertical direction (for example, ice is more likely to accumulate below the power transmission line), if the installation height of the ice sensor is incorrect, it needs to be measured again and the hole needs to be drilled again in the angle steel for installation. The process is extremely cumbersome, time-consuming and labor-intensive.

[0031] The tower body of a transmission tower includes:

[0032] Main materials: Four angle steels (commonly made of Q345B material) form the four corners of the tower body, and the cross-sectional dimensions increase with the height (e.g., L200×18 at the bottom → L90×8 at the top).

[0033] Diagonal members: intersecting angle steel / round steel to form a truss shear-resistant structure (such as K-type or X-type arrangement).

[0034] Auxiliary materials: Angle steel / round steel horizontal diaphragms to prevent structural distortion (one diaphragm every 10-15m).

[0035] Please see Figures 1 to 7 The icing monitoring device for transmission lines provided by this utility model will now be described. The icing monitoring device includes a mounting rod 10, an adjusting bracket 20, a sliding rod 30, a locking element 22, and an icing sensor 41. The mounting rod 10 is mounted on the angle steel 1 of the transmission tower, and a control box 40 is mounted on the mounting rod 10. The adjusting bracket 20 is mounted on the mounting rod 10 and extends outwards. The outer end of the adjusting bracket 20 is connected to a sliding sleeve 21 extending vertically along a main shaft. The sliding rod 30 is slidably connected within the sliding sleeve 21, and a plurality of locking holes 31 are provided on the side wall of the sliding rod 30 at intervals along the axial direction of the sliding rod 30. The locking element 22 is mounted on the sliding sleeve 21 and is used to engage with one of the locking holes 31. The icing sensor 41 is mounted on the sliding rod 30 and electrically connected to the control box 40, and is used to monitor the icing thickness of the transmission line.

[0036] Furthermore, a storage battery is installed inside the control box 40.

[0037] This application provides a transmission line icing monitoring device. In actual use, the device is installed on the upper part of the transmission tower, close to the height of the transmission line to be monitored. The sliding fit between the sliding sleeve 21 and the sliding rod 30, combined with the locking hole 31 structure, allows the icing sensor 41 to be flexibly adjusted in the vertical direction to adapt to different conductor heights and dynamic monitoring needs of icing growth.

[0038] The icing sensor 41 is directly fixed to the slide bar 30, which reduces mechanical vibration interference and improves the accuracy of the icing thickness data.

[0039] When it is necessary to adjust the vertical height of the icing sensor 41, release the locking member 22, slide the slider 30 up and down, and after the adjustment is completed, the locking member 22 is inserted and locked into the corresponding locking hole 31, thereby completing the quick adjustment of the vertical height of the icing sensor 41, saving time and effort.

[0040] Compared with the prior art, the transmission line icing monitoring device provided in this embodiment can quickly adjust the vertical height of the icing sensor 41 by releasing the locking member 22 and sliding the slide rod 30 up and down when the vertical height of the icing sensor 41 needs to be adjusted. After the adjustment is completed, the locking member 22 is inserted and locked into the corresponding locking hole 31, thereby completing the quick adjustment of the vertical height of the icing sensor 41, saving time and effort.

[0041] In one possible implementation, the locking element 22 is adopted as follows: Figure 1 and Figure 2The structure shown is described in the following document. Figure 1 and Figure 2 The locking element 22 is radially inserted through the outer peripheral wall of the sliding sleeve 21 and is threadedly connected to the sliding sleeve 21.

[0042] Specifically, the threaded locking member 22 can radially tighten the slide bar 30 to prevent displacement of the slide bar 30 due to the impact of wind or ice falling off, thus ensuring long-term monitoring stability.

[0043] Compared to elastic snaps, threaded engagement is more resistant to low-temperature deformation and is suitable for extremely cold regions (such as -30℃ environments), avoiding the risk of traditional spring locks failing due to icing.

[0044] In one possible implementation, the slide bar 30 described above adopts the following... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The upper end of the slide rod 30 is connected to an upwardly extending threaded post 32. A limiting nut 33 is threaded around the outer periphery of the threaded post 32. The slide rod 30 can drive the limiting nut 33 to move downward and abut against the upper end surface of the slide sleeve 21 to limit the axial displacement of the slide rod 30.

[0045] Specifically, the threaded post 32 and the limiting nut 33 form a mechanical hard limit. After the slide rod 30 moves down to the limit position, the limiting nut 33 can abut against the upper end face of the sliding sleeve 21 to limit it, preventing the slide rod 30 from moving down too far and disengaging from the sliding sleeve 21. This avoids the slide rod 30 causing the icing sensor 41 to fall to the ground and be damaged during the adjustment process.

[0046] In one possible implementation, the mounting rod 10 described above adopts the following... Figure 1 , Figure 2 and Figures 4 to 6 The structure shown is described in the following document. Figure 1 , Figure 2 and Figures 4 to 6 The mounting rod 10 is provided with a lower wing plate 50 connected to the outside of the angle steel 1 by the first bolt assembly 51.

[0047] Specifically, the first bolt assembly 51 passes through the lower flange 50 and the limb of the angle steel 1 that fits against the lower flange 50. The lower flange 50 and the angle steel 1 are connected by bolts, eliminating the need for welding and shortening the installation time.

[0048] Furthermore, the first bolt assembly 51 includes a bolt and a nut that is threadedly connected to the bolt.

[0049] In some embodiments, see Figures 4 to 6A horizontally extending adjustment hole 52 is provided through the lower wing plate 50. In the extension direction of the adjustment hole 52, the diameter of the adjustment hole 52 gradually increases. The two ends of the adjustment hole 52 are defined as its large diameter end and its small diameter end, respectively. The large diameter end of the adjustment hole 52 is suitable for the first bolt assembly 51 to pass through, and the small diameter end of the adjustment hole 52 is suitable for engaging with the first bolt assembly 51.

[0050] Specifically, when disassembly is required, simply loosen the first bolt assembly 51, then slide the lower wing plate 50 horizontally to allow the first bolt assembly 51 to enter the large-diameter end of the adjustment hole 52, and finally pull the lower wing plate 50 outward to separate it from the first bolt assembly 51. The lower wing plate 50 and the angle steel 1 can be quickly disassembled without disassembling the first bolt assembly 51, thus improving disassembly efficiency.

[0051] Furthermore, the large-diameter end allows the bolt head to pass through quickly, reducing installation and positioning time.

[0052] In some embodiments, see Figure 6 The upper edge of the lower wing plate 50 is connected to an upper wing plate 60 extending above the angle steel 1. A first mating hole 61 extending along the direction of the adjustment hole 52 is provided through the upper wing plate 60. A second mating hole 62 communicating with the first mating hole 61 is provided through the upper wing plate 60. The second mating hole 62 extends away from the lower wing plate 50 to the side edge of the upper wing plate 60. The upper wing plate 60 is connected to the angle steel 1 by a second bolt assembly 63 passing through the first mating hole 61.

[0053] Specifically, when the first bolt assembly 51 is located within the large-diameter end of the adjusting hole 52, the second bolt assembly 63 is located within the second mating hole 62; when the lower wing plate 50 disengages from the first bolt assembly 51, the second bolt assembly 63 separates from the second mating hole 62.

[0054] Specifically, the extension direction of the adjustment hole 52 is defined as the front-back direction, the large-diameter end is the front end of the adjustment hole 52, the second mating hole 62 is connected to the front end of the first mating hole 61, and the second mating hole 62 and the first mating hole 61 form an L-shaped locking groove.

[0055] When disassembly is required, first loosen the first bolt assembly 51 and the second bolt assembly 63, then push the lower wing plate 50 or the upper wing plate 60 horizontally until the first bolt assembly 51 moves to the large diameter end. The second bolt assembly 63 then gradually enters the second mating hole 62. Next, pull the lower wing plate 50 away from the angle steel 1 to separate the lower wing plate 50 from the first bolt assembly 51. During the pulling process, the second bolt assembly 63 also disengages from the upper wing plate 60 at the tail end of the second mating hole 62, enabling quick disassembly by a single person.

[0056] In one possible implementation, the aforementioned adjusting bracket 20 adopts as follows: Figure 1 The structure shown is described in the following document. Figure 1Two adjustment brackets 20 are spaced apart along the vertical direction. Each adjustment bracket 20 is equipped with a slide rod 30. One slide rod 30 is equipped with an icing sensor 41, and the other slide rod 30 is equipped with a six-element miniature weather instrument 42 that is electrically connected to the control box 40.

[0057] Specifically, each adjustment bracket 20 is equipped with a locking element 22.

[0058] Ice sensor 41 monitors ice thickness, and six-element meteorological instrument collects temperature, humidity, wind, pressure, rain, and light data to establish an icing rate prediction model.

[0059] The six-element meteorological instrument (temperature / humidity / wind / pressure / rain / light) can also perform fine-tuning of altitude. Its function goes far beyond simple position changes. It matches the micro-meteorological layer of the power transmission line with centimeter-level precision, solving the systematic errors caused by altitude deviation in traditional monitoring.

[0060] In one possible implementation, the aforementioned adjusting bracket 20 adopts as follows: Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The adjusting bracket 20 is fixed to the mounting rod 10 by two clamping hoops 70 that clamp around the outer periphery of the mounting rod 10, and the two clamping hoops 70 are connected by a fastener 71.

[0061] Specifically, the two clamping hoops 70 symmetrically enclose the mounting rod 10 at 180°, increasing the contact area and improving the bending moment bearing capacity under typhoon conditions. The clamping hoop 70 structure also avoids welding or drilling on the mounting rod 10, maintaining its integrity and strength. The clamping hoop 70 is lined with a neoprene rubber pad to absorb low-frequency vibration energy transmitted by power line galloping, reducing the risk of equipment resonance.

[0062] In one possible implementation, the mounting rod 10 described above adopts the following... Figure 1 , Figure 3 , Figure 4 and Figure 7 The structure shown is described in the following document. Figure 1 , Figure 3 , Figure 4 and Figure 7 The mounting rod 10 is equipped with a solar panel 43 that is electrically connected to the control box 40. The solar panel 43 is mounted on the mounting rod 10 via a fixing bracket 80. The fixing bracket 80 is equipped with a main clamp 81 and a secondary clamp 82 that hug the outer periphery of the mounting rod 10. The main clamp 81 and the secondary clamp 82 are connected by a connector 90.

[0063] Specifically, the daily power generation of the solar panel 43 is sufficient to power the control box 40, the icing sensor 41, the six-element weather instrument, and the 4G module.

[0064] The mounting bracket 80 (supporting the solar panel 43) is installed by using a main clamp 81 and a secondary clamp 82 to be fixed to the mounting rod 10 via a connector 90, providing an extremely stable and load-bearing installation platform.

[0065] The clamp structure also avoids welding or drilling on the mounting rod 10, maintaining the integrity and strength of the mounting rod 10.

[0066] Furthermore, the connector 90 includes a bolt passing through the main clamp 81 and the secondary clamp 82, and a nut threadedly connected to the bolt.

[0067] In some embodiments, see Figure 3 and Figure 7 Two secondary clamps 82 are provided at intervals along the vertical direction.

[0068] Specifically, two secondary clamps 82 are installed at intervals along the vertical axis of the mounting rod 10, increasing the number of fixing points between the fixing bracket 80 and the mounting rod 10 from one to two (two secondary clamps 82). This greatly enhances the rigidity, stability, and wind and torsional resistance of the entire solar panel 43 support structure.

[0069] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
