[0002] In overhead transmission lines, transmission wires are installed between transmission towers. Transmission towers are important carriers of electric energy transmission. They operate in complex outdoor environments for a long time and are easily affected by multiple complex disasters such as wind, ice, and geology. In order to timely grasp the safety status of transmission towers, it is necessary to accurately monitor and evaluate the force distribution characteristics of transmission towers. The industry usually analyzes the force distribution characteristics of transmission towers by installing strain sensors on transmission towers.

[0037] See also Figure 1 and Figure 2 , Figure 1 is a schematic top view of the auxiliary mounting device 10 in some embodiments, Figure 2Schematic diagram of the installation position 221 of the strain sensor 30 on the rod 20 in some embodiments. The auxiliary installation device 10 provided in the present application includes but is not limited to being used to assist the installation of the strain sensor 30 on the rod 20 of the transmission tower. For example, when the strain sensor 30 needs to be installed on the rod 20, the installation position 221 of the strain sensor 30 on the rod 20 can be determined by the auxiliary installation device 10 first, and then the strain sensor 30 can be installed on the installation position 221 determined by the auxiliary installation device 10, thereby improving the installation accuracy of the strain sensor 30 on the rod 20, reducing the influence of the error of the installation position 221 of the strain sensor 30 on the monitoring effect, which is conducive to improving the monitoring efficiency and accuracy of the strain sensor 30 on the transmission tower. The transmission tower involved in the present application includes but is not limited to being used in overhead transmission lines. The transmission tower can be used as one of the carriers for power transmission, and the transmission wires in the overhead transmission line can be erected between the transmission towers. The rod 20 of the transmission tower includes but is not limited to angle steel, and at least part of the transmission tower is composed of angle steel. The strain sensor 30 includes but is not limited to being installed on the angle steel of the transmission tower. The strain sensor 30 is arranged on the transmission tower to monitor the force distribution characteristics of the rod 20, so as to characterize the influence of wind, ice, geology and other composite disasters on the transmission tower, and improve the reliability and safety performance of the use of the transmission tower.

[0038] It should be noted that, depending on the position of the rod 20 on the transmission tower, the shape and size of the rod 20, the environmental conditions around the transmission tower, and the different requirements for force monitoring, the number of strain sensors 30 on the rod 20 and the distribution of the installation positions 221 are also different. In the process of installing the strain sensor 30 on the rod 20, the number of strain sensors 30 on the rod 20 and the distribution of the installation positions 221 can be obtained according to the above conditions, and then the auxiliary installation device 10 is used to accurately calibrate each installation position 221, and then the strain sensor 30 is installed on the rod 20 according to the calibrated installation position 221.

[0039] refer to Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the auxiliary installation device 10 includes a first clamping plate assembly, a second clamping plate assembly and a positioning element 13. The first clamping plate assembly includes two opposite first clamping plates 11, the two first clamping plates 11 can be relatively close to or away from each other and are used to be clamped on two opposite sides of the rod 20. The second clamping plate assembly includes two opposite second clamping plates 12, the two second clamping plates 12 correspond to the two first clamping plates 11 one by one, each second clamping plate 12 is arranged on a corresponding first clamping plate 11, and can slide relative to the corresponding first clamping plate 11 along a first direction 17. When the two first clamping plates 11 are relatively away from each other so that a gap is generated between the two first clamping plates 11, the two second clamping plates 12 can slide relative to the first clamping plates 11 to extend from the first clamping plates 11 to the gap between the two first clamping plates 11. The positioning element 13 is arranged on at least one first clamping plate 11, and can slide relative to the first clamping plate 11 along a second direction 18. When the two first clamping plates 11 are relatively far apart so that a gap is generated between the two first clamping plates 11, at least a portion of the positioning element 13 is located between the two first clamping plates 11. For example, when the two first clamping plates 11 are relatively close to each other and no gap exists, two portions of the vertical projection of the positioning element 13 on the first clamping plates 11 may fall on the two first clamping plates 11 respectively, so that when the two first clamping plates 11 are relatively far apart and a gap is generated, a portion of the positioning element 13 is located in the gap between the two first clamping plates 11.

[0040] In some embodiments, the rod 20 may have two opposite side surfaces 21 and a mounting surface 22 for mounting the strain sensor 30, the mounting surface 22 is located between the two side surfaces 21, the mounting surface 22 may be connected to the two side surfaces 21, and the two first clamping plates 11 may be clamped on the two side surfaces 21 of the rod 20. When the two first clamping plates 11 are clamped on the two side surfaces 21 of the rod 20, the orthographic projections of the two second clamping plates 12 and the positioning element 13 on the rod 20 may at least partially fall on the mounting surface 22, and the first direction 17 and the second direction 18 may be understood as two mutually perpendicular directions on a plane parallel to the mounting surface 22.

[0041] It is understandable that, in the process of installing the strain sensor 30 on the rod 20, the installation position 221 of the strain sensor 30 on the installation surface 22 can be obtained by any applicable method such as calculation, simulation, etc., and then the first clamping plate assembly is clamped on the two side surfaces 21 of the rod 20, so that the two first clamping plates 11 are relatively fixed to the rod 20, so that the second clamping plate 12 and the positioning element 13 can move relative to the rod 20 with the first clamping plate 11 as a reference when they move relative to the first clamping plate 11. When the two first clamping plates 11 are clamped on the two side surfaces 21 of the rod 20, the two first clamping plates 11 are spaced to form a gap, the installation surface 22 is exposed in the gap between the two first clamping plates 11, and the installation position 221 is located in the portion of the installation surface 22 exposed in the gap between the two first clamping plates 11. The positioning element 13 is driven to move relative to the rod 20 along the second direction 18, and the displacement of the positioning element 13 relative to the first clamping plate 11 in the second direction 18 is adjusted. The portion of the rod 20 located in the gap between the two first clamping plates 11 can calibrate the installation position 221 of the strain sensor 30 in the first direction 17. The two opposing surfaces of the two second clamping plates 12 can be used as positioning surfaces 121, and the two second clamping plates 12 are driven to slide relative to the first clamping plates 11 to extend out of the gap between the two first clamping plates 11. By adjusting the displacement of the two second clamping plates 12 relative to the first clamping plates 11 in the first direction 17, the positioning surfaces 121 of the two second clamping plates 12 are located in the gap between the two first clamping plates 11, and the two positioning surfaces 121 can calibrate the two opposing edges of the installation position 221 of the strain sensor 30 in the second direction 18.

[0042] Therefore, the second clamping plate assembly and the positioning element 13 cooperate to accurately calibrate the installation position 221 of the strain sensor 30 in both the first direction 17 and the second direction 18, reduce the deviation between the actual installation position 221 and the calculated or simulated installation position 221, thereby completing the precise installation of the strain sensor 30 on the rod 20, and improving the installation accuracy of the strain sensor 30 on the installation surface 22, which is beneficial to improve the monitoring efficiency and accuracy of the strain sensor 30 on the transmission tower.

[0043] Please see again Figure 1 and Figure 2It can be understood that when the strain sensor 30 is roughly in the shape of a cube, the installation position 221 of the strain sensor 30 on the installation surface 22 is roughly in the shape of a square, and the two positioning surfaces 121 of the second clamping plate 12 can calibrate the contours of the two opposite edges of the installation position 221 in the first direction 17 in the second direction 18. The positioning element 13 can be used to calibrate one of the points of the installation position 221 in the second direction 18, so as to calibrate the position of the installation position 221 in the second direction 18 through the correspondence between the positions of the glue points, welding points, shape or pattern identification points on the strain sensor 30 and the points calibrated by the positioning element 13. After the installation position 221 is calibrated by the auxiliary installation device 10, the opposite sides of the strain sensor 30 are aligned with the two positioning surfaces 121, and the points on the strain sensor 30 are aligned with the points calibrated by the positioning element 13, and the strain sensor 30 can be accurately installed at the installation position 221 by any applicable method such as glue points and welding.

[0044] It should be noted that only one strain sensor 30 may be provided on one mounting surface 22 of the rod 20, or a plurality of strain sensors 30 may be provided. Figure 2 The solid line box on the middle mounting surface 22 indicates the installed strain sensor 30, and the dotted line box indicates the position 221 to be installed of other strain sensors 30 in one embodiment. It can be understood that after one of the installation positions 221 is calibrated by the movement of the first clamping plate 11 and the positioning element 13 relative to the first clamping plate 11, and one of the strain sensors 30 is installed, the first clamping plate 11 and the positioning element 13 can be driven again to move relative to the first clamping plate 11 to calibrate another installation position 221, so that multiple strain sensors 30 can be installed on the mounting surface 22. When multiple strain sensors 30 are installed on the mounting surface 22, the multiple strain sensors 30 can cooperate with each other to monitor the rod 20 at the same time to fully obtain the force distribution characteristics of the transmission tower. The multiple strain sensors 30 can also be a main strain sensor 30 and a backup strain sensor 30, respectively. The backup strain sensor 30 can be operated when the main strain sensor 30 fails to improve the reliability of monitoring.

[0045] Please see again Figure 1In some embodiments, at least one first clamping plate 11 is provided with a slide groove 1123 extending along the second direction 18, and a portion of the positioning element 13 is slidably disposed in the slide groove 1123 so as to be able to slide relative to the first clamping plate 11 in the second direction 18. In some embodiments, the first clamping plate 11 is further provided with a first scale mark 1124 disposed along the second direction 18 and corresponding to the slide groove 1123. The first scale mark 1124 may be a size scale mark. The type and graduation value of the first scale mark 1124 are not limited and may be specifically set according to the accuracy requirements of the installation position 221. Setting the first scale mark 1124 can accurately obtain the position and displacement of the positioning element 13 sliding along the slide groove 1123, thereby facilitating the accurate calibration of the installation position 221 in the second direction 18. The first scale mark 1124 may be disposed adjacent to the slide groove 1123, for example, the first scale mark 1124 and the slide groove 1123 are both located at one edge of a surface of the first clamping plate 11.

[0046] Further, in some embodiments, the two first clamping plates 11 are provided with a slide groove 1123 and a first scale mark 1124 arranged along the second direction 18, and the slide groove 1123 and the first scale mark 1124 on each first clamping plate 11 are arranged correspondingly. The positioning element 13 includes a first shaft portion 131 and a second shaft portion 132 extending along the first direction 17, and the ends of the first shaft portion 131 and the second shaft portion 132 close to each other are slidably connected to each other, and the relative sliding direction of the first shaft portion 131 and the second shaft portion 132 is parallel to the first direction 17. The end of the first shaft portion 131 away from the second shaft portion 132 and the end of the second shaft portion 132 away from the first shaft portion 131 are respectively slidably arranged in the slide grooves 1123 of the two first clamping plates 11. The two ends of the positioning element 13 can be set as spherical or cube-shaped sliders, and are slidably arranged in the slide grooves 1123.

[0047] It can be understood that when the two first clamping plates 11 are relatively far away from each other, the first shaft portion 131 and the second shaft portion 132 can also be relatively far away from each other along with the first clamping plates 11, and the first scale marks 1124 on the two first clamping plates 11 can provide a reference for the position and displacement of the positioning element 13 in the second direction 18, and can prevent the positioning element 13 from swinging in the first direction 17 and affecting the positioning accuracy. Thus, the structural reliability and calibration accuracy of the auxiliary installation device 10 can be improved. The specific arrangement of the first shaft portion 131 and the second shaft portion 132 is not limited, as long as the first shaft portion 131 and the second shaft portion 132 can slide relative to each other along with the relative movement of the two first clamping plates 11. For example, a cavity can be provided at the end of one of the first shaft portion 131 and the second shaft portion 132, and the end of the other extends into the cavity so that the first shaft portion 131 and the second shaft portion 132 can be slidably connected to each other.

[0048] Combination Figure 1 and Figure 3 As shown, in some embodiments, the auxiliary installation device 10 further includes a sliding seat 14, and the two first clamping plates 11 are slidably disposed on the sliding seat 14, and the sliding direction of the two first clamping plates 11 on the sliding seat 14 is parallel to the first direction 17. The provision of the sliding seat 14 can limit the relative movement direction of the two first clamping plates 11, which is conducive to improving the calibration accuracy of the auxiliary installation device 10. In some embodiments, two sliding seats 14 can be provided, and the two sliding seats 14 are respectively disposed at the two ends of the first clamping plate 11 in the second direction 18. The sliding seat 14 can be roughly in the shape of a rod extending along the first direction 17. The two sliding seats 14 can effectively improve the structural and operational reliability of the auxiliary installation device 10.

[0049] Furthermore, in some embodiments, the auxiliary installation device 10 further includes an elastic mechanism, which is connected to the two first clamping plates 11 and can be stretched when the two first clamping plates 11 are away from each other so that the two first clamping plates 11 have a tendency to approach each other. When the two first clamping plates 11 are away from each other to adapt to the distance between the two side surfaces 21 of the rod 20, so that the two first clamping plates 11 are clamped on the two side surfaces 21, the elastic mechanism is stretched, and the elastic restoring force of the elastic mechanism can make the two first clamping plates 11 have a tendency to move toward each other, so that the two first clamping plates 11 clamp the rod 20 and are fixed relative to the rod 20, so as to avoid the first clamping plates 11 from moving relative to the rod 20 during the calibration process, which is conducive to improving the calibration accuracy.

[0050] The specific arrangement of the elastic mechanism is not limited, as long as the two first clamping plates 11 can clamp the two side surfaces 21 of the rod 20. Figure 3 In the embodiment, the elastic mechanism has two elastic elements 15, including but not limited to springs or torsion springs, one end of the two elastic elements 15 is respectively connected to the two first clamping plates 11, and the other end can be connected to the sliding seat 14. In other embodiments, the elastic mechanism can also be provided with an elastic element 15, and the two ends of the elastic element 15 are respectively connected to the two first clamping plates 11.

[0051] Combination Figure 1 and Figure 4As shown, in some embodiments, the two positioning surfaces 121 of the two second clamping plates 12 are arranged opposite to each other and are parallel to the second direction 18, and the sliding seat 14 is provided with a second scale mark 141 arranged along the first direction 17, and the second scale mark 141 at least covers the sliding stroke of the two positioning surfaces 121 in the first direction 17. The second scale mark 141 includes but is not limited to a size scale, and when the second clamping plate 12 extends out of the gap between the two first clamping plates 11, the position and displacement of the two positioning surfaces 121 in the first direction 17 can be accurately determined with the second scale mark 141 as a reference, so as to help improve the calibration accuracy of the second clamping plate 12 for the installation position 221.

[0052] The specific configuration of the first clamping plate 11 is not limited, as long as it can be clamped on both sides of the rod 20 and serve as a movement reference for the positioning element 13 and the second clamping plate 12. In some embodiments, the first clamping plate 11 includes a clamping portion 111 and a limiting portion 112 connected to each other, at least a portion of the limiting portion 112 is used to fit with the mounting surface 22, at least a portion of the clamping portion 111 is used to fit with the side surface 21, and the second clamping plate 12 and the positioning element 13 are slidably arranged on the limiting portion 112. The clamping portion 111 and the limiting portion 112 can both be roughly plate-shaped. When the two first clamping plates 11 are clamped on both sides of the rod 20, the extension direction of the limiting portion 112 is roughly parallel to the mounting surface 22, one of the surfaces of the limiting portion 112 fits with the mounting surface 22, and the clamping portion 111 is connected to the surface of the limiting portion 112 and fits with the side surface 21 of the rod 20. The two limiting portions 112 are spaced apart to expose a portion of the installation surface 22 . The positioning element 13 and the second clamping plate 12 can calibrate the installation position 221 of the strain sensor 30 in the gap between the two limiting portions 112 .

[0053] Combination Figure 4 and Figure 5 As shown, the limiting portion 112 is provided with a slideway 1125 extending along the first direction 17, and the two slideways 1125 respectively form opposite openings on the two opposite surfaces of the two limiting portions 112, and the second clamping plate 12 can be slidably arranged in the slideway 1125, and can extend from the opening to the gap between the two clamping portions 111. When the first clamping plate 11 is clamped on both sides of the rod 20, by driving the second clamping plate 12 to slide along the slideway 1125 relative to the first clamping plate 11 so that the positioning surface 121 extends out of the gap between the two limiting portions 112, the position change of the second clamping plate 12 relative to the first clamping plate 11 is adjusted with the second scale mark 141 as a reference, and the two opposite edges of the installation position 221 can be calibrated.

[0054] refer to Figure 4 and Figure 6As shown, in some embodiments, the limiting portion 112 includes two opposite limiting plates 1121 and a side plate 1122 connected to the two limiting plates 1121, wherein one of the limiting plates 1121 faces the side of the clamping portion 111 and is used to fit with the mounting surface 22, the slide groove 1123 and the first scale mark 1124 can be provided on the side of the other limiting plate 1121 facing away from the mounting surface 22, and the slideway 1125 is formed between the two limiting plates 1121. In some embodiments, the auxiliary installation device 10 further includes an adjustment mechanism 16, the adjustment mechanism 16 penetrates the side plate 1122 and penetrates into the slideway 1125 to connect with the second clamping plate 12, and the part of the adjustment mechanism 16 located outside the limiting portion 112 can rotate to drive the second clamping plate 12 to slide along the slideway 1125. The adjustment mechanism 16 includes but is not limited to an adjustment structure such as a screw, and the provision of the adjustment mechanism 16 can improve the controllability of the sliding displacement of the second clamping plate 12 relative to the first clamping plate 11, which is conducive to improving the calibration accuracy of the auxiliary installation device 10.

[0055] Based on the auxiliary installation device 10 described in any of the above embodiments, the present application further provides an auxiliary installation method for calibrating the installation position 221 of the strain sensor 30 on the rod 20 to assist in the installation of the strain sensor 30 and improve the installation accuracy. In some embodiments, the auxiliary installation method includes:

[0056] The two first clamping plates 11 are driven to move away from each other and clamped on two opposite sides of the rod 20 of the transmission tower;

[0057] Driving the positioning element 13 to slide along the mounting surface 22 of the rod 20 in the second direction 18 to calibrate the mounting position 221 of the strain sensor 30 on the mounting surface 22 in the second direction 18;

[0058] The two second clamping plates 12 are driven to slide along the mounting surface 22 relative to the first clamping plates 11 in the first direction 17 so as to extend between the two first clamping plates 11, and two opposite positioning surfaces 121 of the two second clamping plates 12 define two opposite edges of the mounting position 221 of the strain sensor 30 on the mounting surface 22;

[0059] The strain sensor 30 is mounted on the mounting surface 22 using the positioning element 13 and the positioning surface 121 as a reference.

[0060] It should be noted that before the auxiliary installation method is adopted, the installation position 221 of the strain sensor 30 on the rod 20 can be obtained by simulation, calculation, etc., and then the auxiliary installation method is adopted to accurately calibrate the installation position 221 by using the positioning element 13 and the positioning surface 121, with the first scale mark 1124 and the second scale mark 141 as the accuracy reference. The specific settings of each step of the auxiliary installation method can be obtained by referring to the above records. By adopting the above auxiliary installation method, the installation position 221 of the strain sensor 30 on the rod 20 can be accurately calibrated, the deviation between the actual installation position 221 and the installation position 221 obtained by calculation and simulation can be reduced, and the installation accuracy of the strain sensor 30 on the rod 20 can be improved, which is conducive to improving the monitoring efficiency and accuracy of the strain sensor 30 on the transmission tower.
