Description

Technical Field

[0001] The present application relates to the technical field of transmission line tower monitoring operations, and in particular to an auxiliary installation device and an auxiliary installation method. Background Art

[0002] In overhead transmission lines, transmission conductors are strung between transmission towers. Transmission towers are crucial for power transmission and operate in complex outdoor environments for extended periods, making them susceptible to multiple hazards, including wind, ice, and geological hazards. Accurately monitoring and assessing the stress distribution characteristics of transmission towers is crucial to maintaining a reliable understanding of their safety. The industry typically analyzes these stress distribution characteristics by installing strain sensors on transmission towers. However, in traditional overhead transmission lines, the accuracy of strain sensor installation on transmission towers is difficult to guarantee, impacting the efficiency and accuracy of strain sensor monitoring. Summary of the Invention

[0007] A positioning element is provided on at least one of the first clamping plates and is capable of sliding relative to the first clamping plate along a second direction. When the two first clamping plates are relatively far apart, at least a portion of the positioning element is located between the two first clamping plates, and the first direction and the second direction are perpendicular to each other.

[0008] When the auxiliary installation device is used to assist in the installation of the strain sensor on the rod of the transmission tower, it is first clamped on two opposite sides of the rod through the clamping plate assembly, so that the first clamping plate is relatively fixed to the rod, thereby allowing the second clamping plate assembly and the positioning element to move relative to the rod with the first clamping plate assembly as a reference. The sliding of the positioning element relative to the rod in the second direction can calibrate the installation position of the strain sensor on the rod along the first direction, and the sliding of the two second clamping plates relative to the rod in the first direction can calibrate the two opposite edges of the installation position of the strain sensor on the rod along the second direction. In this way, the installation position of the strain sensor on the rod can be determined with the positioning element and the second clamping plate as references in two directions perpendicular to each other, completing the precise installation of the strain sensor on the rod, which is conducive to improving the accuracy of the installation of the strain sensor on the rod, thereby improving the efficiency and accuracy of the strain sensor's monitoring of the transmission tower.

[0011] In one embodiment, the auxiliary installation device further includes a sliding seat, the two first clamping plates are slidably disposed on the sliding seat, and the sliding direction of the two first clamping plates on the sliding seat is parallel to the first direction.

[0012] In one embodiment, the auxiliary installation device further includes an elastic mechanism, which is connected to the two first clamping plates and can be stretched when the two first clamping plates move away from each other so that the two first clamping plates have a movement tendency to move closer to each other.

The first clamping plate includes a clamping portion and a limiting portion that are interconnected. At least a portion of the limiting portion is used to fit with the mounting surface, and at least a portion of the clamping portion is used to fit with the side surface.

[0015] In one embodiment, the limiting portion is provided with a slide extending along the first direction, the slide forming opposite openings on two opposite surfaces of the two limiting portions, and the second clamping plate is slidably disposed in the slide.

[0016] In one embodiment, the limiting portion includes two opposite limiting plates and side plates connected to the two limiting plates, wherein one of the limiting plates faces the side of the clamping portion and is used to fit with the mounting surface, and the slide is formed between the two limiting plates. The auxiliary installation device also includes an adjustment mechanism, which passes through the side plates and extends into the slide to be connected to the second clamping plate.

[0037] See 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 this application includes but is not limited to being used to assist in 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 at 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 and reducing the impact 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 this 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 electric energy transmission, and the transmission wires in the overhead transmission line can be erected between the transmission towers. The transmission tower's members 20 include, but are not limited to, angle steel. The tower is at least partially constructed of angle steel. The strain sensors 30 are, but are not limited to, mounted on the angle steel. Installing the strain sensors 30 on the tower monitors the force distribution characteristics of the members 20, characterizing the tower's exposure to multiple combined disasters, such as wind, ice, and geology, thereby improving the tower's reliability and safety.

[0038] It should be noted that the number of strain sensors 30 on the rod 20 and the distribution of the installation locations 221 vary depending on the position of the rod 20 on the transmission tower, the shape and size of the rod 20, the environmental conditions surrounding the transmission tower, and the requirements for force monitoring. During the installation of the strain sensors 30 on the rod 20, the number of strain sensors 30 on the rod 20 and the distribution of the installation locations 221 can be determined based on the aforementioned conditions. The auxiliary installation device 10 can then be used to precisely calibrate each installation location 221. The strain sensors 30 can then be installed on the rod 20 according to the calibrated installation locations 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, and the two first clamping plates 11 can be relatively close to or away from each other and are used to be clamped on opposite sides of the rod 20. The second clamping plate assembly includes two opposite second clamping plates 12, and the two second clamping plates 12 correspond to the two first clamping plates 11 one by one. Each second clamping plate 12 is provided 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 plate 11 to extend from the first clamping plate 11 to the gap between the two first clamping plates 11. The positioning element 13 is provided 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 splints 11 are relatively far apart such that a gap is formed between the two first splints 11, at least a portion of the positioning element 13 is located between the two first splints 11. For example, when the two first splints 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 splint 11 may fall onto the two first splints 11, respectively. Thus, when the two first splints 11 are relatively far apart such that a gap is formed, the positioning element 13 is partially located in the gap between the two first splints 11.

[0040] In some embodiments, the rod 20 may have two opposing 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 and may be connected to the two side surfaces 21. The two first clamping plates 11 may be clamped to the two side surfaces 21 of the rod 20. When the two first clamping plates 11 are clamped to 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. The first direction 17 and the second direction 18 can be understood as two mutually perpendicular directions on a plane parallel to the mounting surface 22.

[0041] It will be appreciated that, during the process of mounting the strain sensor 30 on the rod 20, the mounting position 221 of the strain sensor 30 on the mounting surface 22 can be first obtained through calculation, simulation, or any other suitable method. The first clamping plate assembly is then clamped to the two side surfaces 21 of the rod 20, so that the two first clamping plates 11 are fixed relative to the rod 20. This allows the second clamping plate 12 and the positioning element 13 to move relative to the rod 20 with the first clamping plate 11 as a reference when the second clamping plate 12 and the positioning element 13 move relative to the first clamping plate 11. When the two first clamping plates 11 are clamped to the two side surfaces 21 of the rod 20, the two first clamping plates 11 are spaced apart to form a gap, and the mounting surface 22 is exposed in the gap between the two first clamping plates 11. The mounting position 221 is located in the portion of the mounting surface 22 exposed in the gap between the two first clamping plates 11. By driving the positioning element 13 to move relative to the rod 20 in the second direction 18 and adjusting the displacement of the positioning element 13 relative to the first clamping plate 11 in the second direction 18, 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 serve as positioning surfaces 121. 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 plate 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. 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, reducing the deviation between the actual installation position 221 and the installation position 221 obtained by calculation or simulation, thereby completing the precise installation of the strain sensor 30 on the rod 20, improving the installation accuracy of the strain sensor 30 on the installation surface 22, and thus helping 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 is understood that when the strain sensor 30 is roughly cube-shaped, the installation location 221 of the strain sensor 30 on the installation surface 22 is roughly square. The two positioning surfaces 121 of the second clamping plate 12 can calibrate the contours of the two opposing edges of the installation location 221 in the first direction 17 in the second direction 18. The positioning element 13 can be used to calibrate one point of the installation location 221 in the second direction 18, so that the position of the installation location 221 in the second direction 18 can be calibrated by corresponding the positions of glue points, welding points, shape or pattern identification points on the strain sensor 30 with the points calibrated by the positioning element 13. After the installation location 221 is calibrated using 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. Then, the strain sensor 30 can be precisely installed at the installation location 221 by any suitable method, such as glue points or 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 an installed strain sensor 30, and the dotted-line box indicates a position 221 where other strain sensors 30 are to be installed in one embodiment. It is understandable that after one of the mounting 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 mounting position 221, thereby enabling multiple strain sensors 30 to 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 simultaneously 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. 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 sliding groove 1123 extending along the second direction 18. The positioning element 13 is partially slidably disposed within the sliding 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 sliding groove 1123. The first scale mark 1124 can be a size scale mark. The type and graduation value of the first scale mark 1124 are not limited and can be specifically set according to the precision requirements of the installation position 221. The provision of the first scale mark 1124 enables accurate acquisition of the sliding position and displacement of the positioning element 13 along the sliding groove 1123, thereby facilitating accurate calibration of the installation position 221 in the second direction 18. The first scale mark 1124 can be disposed adjacent to the sliding groove 1123. For example, the first scale mark 1124 and the sliding groove 1123 are both located on one edge of a surface of the first clamping plate 11.

[0046] Furthermore, in some embodiments, both first clamps 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 clamp 11 are correspondingly arranged. The positioning element 13 includes a first shaft portion 131 and a second shaft portion 132 extending along the first direction 17. The ends of the first shaft portion 131 and the second shaft portion 132 that are 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 disposed in the slide grooves 1123 of the two first clamps 11. The two ends of the positioning element 13 can be configured as spherical or cube-shaped sliders and slidably disposed in the slide grooves 1123.

[0047] It can be understood that when the two first clamps 11 are relatively far apart, the first shaft portion 131 and the second shaft portion 132 can also be relatively far apart with the first clamps 11, and the first scale marks 1124 on the two first clamps 11 can provide a reference for the position and displacement of the positioning element 13 in the second direction 18, which can prevent the positioning element 13 from swinging in the first direction 17 and affecting the positioning accuracy. In this way, the structural reliability and calibration accuracy of the auxiliary installation device 10 can be improved. The specific settings of the first shaft portion 131 and the second shaft portion 132 are not limited, as long as the first shaft portion 131 and the second shaft portion 132 can slide relative to each other with the relative movement of the two first clamps 11. For example, the end of one of the first shaft portion 131 and the second shaft portion 132 can be provided with a cavity, 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] Combine Figure 1 and Figure 3 As shown, in some embodiments, the auxiliary installation device 10 further includes a sliding seat 14, on which the two first clamping plates 11 are slidably disposed, 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 beneficial for improving the calibration accuracy of the auxiliary installation device 10. In some embodiments, two sliding seats 14 can be provided, with the two sliding seats 14 being respectively disposed at the two ends of the first clamping plate 11 in the second direction 18. The sliding seats 14 can be generally 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 mounting device 10 further includes an elastic mechanism connected to the two first clamping plates 11 and capable of being stretched when the two first clamping plates 11 are moved away from each other so as to cause the two first clamping plates 11 to tend to move toward each other. When the two first clamping plates 11 move away from each other to accommodate the distance between the two side surfaces 21 of the rod 20, such that the two first clamping plates 11 are clamped between the two side surfaces 21, the elastic mechanism is stretched, and the elastic restoring force of the elastic mechanism causes the two first clamping plates 11 to tend to move toward each other, thereby causing the two first clamping plates 11 to clamp the rod 20 and remain fixed relative to the rod 20, preventing the first clamping plates 11 from moving relative to the rod 20 during the calibration process, thereby improving 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 described above, the elastic mechanism includes two elastic elements 15, including but not limited to springs or torsion springs. One end of each elastic element 15 is connected to each of 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 a single elastic element 15, with both ends of the elastic element 15 connected to each of the two first clamping plates 11.

[0051] Combine Figure 1 and Figure 4As shown, in some embodiments, the two positioning surfaces 121 of the two second clamping plates 12 are arranged opposite each other and are both parallel to the second direction 18. The sliding seat 14 is provided with a second scale mark 141 arranged along the first direction 17. The second scale mark 141 at least covers the sliding travel 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. When the second clamping plate 12 extends out of the gap between the two first clamping plates 11, the second scale mark 141 can be used as a reference to accurately determine the position and displacement of the two positioning surfaces 121 in the first direction 17, thereby facilitating improved calibration accuracy of the second clamping plate 12 relative to 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, and at least a portion of the clamping portion 111 is used to fit with the side surface 21. 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 extending direction of the limiting portion 112 is roughly parallel to the mounting surface 22, one surface 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] Combine Figure 4 and Figure 5 As shown, the limiting portion 112 is provided with a slideway 1125 extending along the first direction 17. The two slideways 1125 respectively form opposing openings on two opposing surfaces of the two limiting portions 112. The second clamping plate 12 is slidably disposed within the slideways 1125 and is capable of extending from the openings into the gap between the two clamping portions 111. When the first clamping plate 11 is clamped on both sides of the rod 20, the second clamping plate 12 is driven to slide relative to the first clamping plate 11 along the slideways 1125 so that the positioning surface 121 extends out of the gap between the two limiting portions 112. The position of the second clamping plate 12 relative to the first clamping plate 11 is adjusted using the second scale mark 141 as a reference, thereby calibrating the two opposing edges of the installation position 221.

[0054] refer to Figure 4 and Figure 6As shown, in some embodiments, the limiting portion 112 includes two opposing limiting plates 1121 and a side plate 1122 connected to the two limiting plates 1121. One of the limiting plates 1121 faces the side of the clamping portion 111 and is configured to engage the mounting surface 22. A slide groove 1123 and a first scale mark 1124 may be provided on the side of the other limiting plate 1121 facing away from the mounting surface 22. A slideway 1125 is formed between the two limiting plates 1121. In some embodiments, the auxiliary mounting device 10 further includes an adjustment mechanism 16, which passes through the side plates 1122 and extends into the slideway 1125 to connect with the second clamping plate 12. The portion of the adjustment mechanism 16 located outside the limiting portion 112 is rotatable 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. 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, thereby improving the calibration accuracy of the auxiliary mounting 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 away from each other and clamped on opposite sides of the pole 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 relative to the first clamping plates 11 along the mounting surface 22 in the first direction 17 so as to extend between the two first clamping plates 11. The two opposing positioning surfaces 121 of the two second clamping plates 12 define two opposing edges of a 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 adopting the auxiliary installation method, the installation position 221 of the strain sensor 30 on the rod 20 can be first obtained through simulation, calculation, or other methods. Then, the auxiliary installation method can be used to accurately calibrate the installation position 221 using the positioning element 13 and the positioning surface 121, with the first scale mark 1124 and the second scale mark 141 as a precision reference. The specific settings of each step of the auxiliary installation method can be obtained by referring to the above description. Using the above-mentioned auxiliary installation method, the installation position 221 of the strain sensor 30 on the rod 20 can be accurately calibrated, reducing the deviation between the actual installation position 221 and the installation position 221 obtained by calculation or simulation, and improving the installation accuracy of the strain sensor 30 on the rod 20, thereby facilitating the improvement of the efficiency and accuracy of the strain sensor 30 monitoring the transmission tower.

[0061] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
