Description

Technical Field

[0001] This application relates to the field of power testing auxiliary equipment technology, and in particular to a multifunctional bracket for precise positioning and measurement under high-voltage lines. Background Technology

[0002] In the daily maintenance, safety inspection, and electromagnetic environment monitoring of high-voltage transmission lines, technicians often need to conduct precise measurements at specific distances directly below and to both sides of the high-voltage lines. These measurement data are crucial for assessing the line's operating status, ensuring its safe and stable operation, and analyzing the surrounding electromagnetic environment. Their accuracy and reliability directly affect the scientific nature of power system safety management and long-term monitoring and analysis.

[0003] However, after determining the point directly beneath the high-voltage line, staff need to measure standard distance points such as 5 meters and 10 meters on both sides. However, existing monitoring methods still rely on primitive methods such as staff pacing or using tape measures. This method is not only inefficient, but more importantly, it is difficult to ensure that the measurement direction is strictly perpendicular to the line. At the same time, due to the lack of accurate directional guidance and standardized measurement methods, the detection data obtained by different personnel at different times often have large differences and lack comparability. This brings great difficulties to the analysis and comparison of long-term monitoring data and seriously affects the scientific nature and application value of the detection results. Utility Model Content

[0004] The purpose of this application is to provide a multifunctional bracket for precise positioning and measurement under high-voltage lines. It avoids the errors of pacing or simple measurement, and can accurately and stably adjust the angle of the laser emitter to ensure that the reference line it projects is parallel to the line and to guarantee the perpendicularity of the measurement direction. It solves the problems mentioned in the background art.

[0005] This application provides a multifunctional support for precise positioning and measurement under high-voltage lines, employing the following technical solution: It includes a base, a first turntable rotatably connected to the upper side of the base, a guide rail fixedly connected to the upper side of the first turntable, a sliding mounting plate slidably connected to the inner side of the guide rail, a laser rangefinder fixedly mounted on the upper side of the sliding mounting plate, two vertical plates fixedly connected to the upper side of the first turntable, a top plate fixedly connected to the upper side of the two vertical plates, a rotating shaft rotatably connected to the inner side of the top plate, a second turntable disposed on the upper side of the top plate, one end of the rotating shaft fixedly connected to the bottom surface of the second turntable, a high-precision adjustment component disposed on the bottom surface of the top plate, a laser transmitter fixedly mounted on the upper side of the second turntable, the high-precision adjustment component including a worm gear fixedly connected to the outer side of the rotating shaft, a worm engaging with the outer side of the worm gear, a signal transmitter fixedly mounted on the bottom surface of the base, and the signal transmitter electrically connected to an external handheld rangefinder.

[0006] By adopting the above technical solution, the laser rangefinder can slide along the guide rail to accurately locate the point directly below the high-voltage line. Then, the signal transmitter works in conjunction with the external handheld rangefinder to accurately measure the distance between the two sides, avoiding the errors of pacing or simple measurement. At the same time, the worm gear and worm in the high-precision adjustment component can accurately adjust the angle of the laser transmitter so that it projects a baseline parallel to the line, ensuring the perpendicularity of the measurement direction to the line direction, and solving the problem of poor comparability of measurement data from different times and personnel.

[0007] Preferably, the sliding mounting plate and the laser rangefinder are fixedly mounted by bolts, and a through hole is provided at the center of the sliding mounting plate for the bottom emitter of the laser rangefinder to pass through. The laser emitter and the second turntable are fixedly connected by bolts.

[0008] By adopting the above technical solution, the bolt connection method facilitates the disassembly and maintenance of the laser rangefinder and laser emitter, ensuring that the equipment can maintain stable performance during long-term use, reducing measurement deviations caused by equipment installation problems, and improving the overall practicality of the device.

[0009] Preferably, the high-precision adjustment assembly further includes two fixed plates fixedly connected to the bottom surface of the top plate, and both ends of the worm gear are rotatably connected to the inner side of the fixed plates.

[0010] By adopting the above technical solution, the fixing plate provides stable support for the worm, ensuring the stability of the meshing transmission between the worm and the worm wheel. At the same time, the rotational self-locking characteristics of the worm and the worm wheel can improve the stability after angle adjustment, making the angle adjustment of the laser emitter more precise and stable, and further ensuring the parallelism between the baseline and the line direction.

[0011] Preferably, a handle is rotatably connected to the inner side of one of the fixing plates, and one end of the handle is fixedly connected to one end of the worm gear, and anti-slip texture is provided on the outer side of the handle.

[0012] By adopting the above technical solution, the aforementioned handle facilitates the operator's rotation of the worm gear, and the anti-slip texture increases hand friction, making the adjustment process more effortless and convenient, improving the efficiency of angle adjustment, reducing operation time, and lowering the risk of personnel exposure under high-voltage lines.

[0013] Preferably, the bottom surface of the base is hinged with three sets of circumferentially arrayed telescopic support legs, and the grounding end of each of the three telescopic support legs is provided with anti-slip texture. A level bubble meter is fixedly installed on the upper side of the first turntable.

[0014] By adopting the above technical solutions, the telescopic support legs can adapt to different terrains, ensuring stable placement of the base. The anti-slip texture enhances grounding stability, while the level bubble meter can assist in adjusting the device's level, providing a horizontal reference for measurement, avoiding measurement errors caused by terrain influences, and improving the device's applicability in complex environments.

[0015] Preferably, a threaded rod is fixedly installed on the outer side of the sliding mounting plate.

[0016] By adopting the above technical solution, the threaded rod can fix the sliding mounting plate at any position on the guide rail, preventing the laser rangefinder from sliding after finding the fixed point, ensuring the stability of the positioning point, and ensuring the accuracy of subsequent measurements.

[0017] Preferably, the inner side of the first turntable is threaded with a threaded rod, one end of which is fixedly connected to a hexagonal block, and the other end of which is fixedly connected to a pressing block.

[0018] By adopting the above technical solution, rotating the hexagonal block can make the extrusion block fit tightly against the base, thereby achieving relative fixation between the first turntable and the base, avoiding the offset of the baseline caused by the rotation of the first turntable during the measurement process, and ensuring the consistency of the measurement direction.

[0019] Preferably, the extrusion block is made of rubber, and the inner side of the extrusion block has an arc-shaped surface that matches the shape of the base.

[0020] By adopting the above technical solution, the rubber extrusion block can increase the friction with the base and improve the fixing effect. At the same time, the arc-shaped surface design makes it fit more tightly with the base, further enhancing the stability of the first turntable and reducing measurement errors caused by device shaking.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This multifunctional support for precise positioning and measurement under high-voltage lines utilizes a laser rangefinder, signal transmitter, and high-precision adjustment components. The laser rangefinder slides along a guide rail to precisely locate directly beneath the high-voltage line. Combined with the signal transmitter and an external handheld rangefinder, it avoids errors associated with pacing or simple measurements. The worm gear and worm shaft in the high-precision adjustment components precisely and stably adjust the laser transmitter angle, ensuring the projected baseline is parallel to the line and guaranteeing the verticality of the measurement direction. Telescopic support legs and a bubble level allow the device to adapt to complex terrain and maintain a horizontal position, enhancing its environmental adaptability. The synergistic effect of the overall structure improves both measurement accuracy and safety. Attached Figure Description

Figure 1 , Figure 2 and Figure 5The system includes a base 1, a first turntable 2 rotatably connected to the upper side of the base 1, a guide rail 3 fixedly connected to the upper side of the first turntable 2, a sliding mounting plate 4 slidably connected to the inner side of the guide rail 3, a laser rangefinder 5 fixedly mounted on the upper side of the sliding mounting plate 4, two vertical plates 6 fixedly connected to the upper side of the first turntable 2, a top plate 7 fixedly connected to the upper side of the two vertical plates 6, a rotating shaft 11 rotatably connected to the inner side of the top plate 7, a second turntable 8 disposed on the upper side of the top plate 7, one end of the rotating shaft 11 fixedly connected to the bottom surface of the second turntable 8, a high-precision adjustment component 9 disposed on the bottom surface of the top plate 7, and a laser emitter 10 fixedly mounted on the upper side of the second turntable 8. The high-precision adjustment component 9 includes... The system includes a worm gear 901 fixedly connected to the outside of the rotating shaft 11, with a worm 902 meshing with the outside of the worm gear 901. The cooperation between the worm gear 901 and the worm 902 can precisely adjust the angle of the laser emitter 10, so that it projects a baseline parallel to the line, ensuring the perpendicularity of the measurement direction to the line direction. A signal transmitter 14 is fixedly installed on the bottom surface of the base 1. The signal transmitter 14 is electrically connected to an external handheld rangefinder. The laser rangefinder 5 can slide along the guide rail 3 to accurately locate the point directly below the high-voltage line. Then, the signal transmitter 14 and the external handheld rangefinder work together to achieve accurate measurement of the distance between the two sides, avoiding the errors of pacing or simple measurement.

[0032] Please refer to Figure 1 and Figure 2 The base 1 has three sets of circumferentially arrayed telescopic support legs 12 hinged to its bottom surface. The grounding ends of the three telescopic support legs 12 are all provided with anti-slip textures. A level bubble meter 13 is fixedly installed on the upper side of the first turntable 2. The telescopic support legs 12 can adapt to different terrains, ensuring the stable placement of the base 1. The anti-slip textures enhance grounding stability. At the same time, the level bubble meter 13 can assist in adjusting the level of the device, providing a horizontal reference for measurement, avoiding measurement errors caused by terrain influences, and improving the applicability of the device in complex environments. The sliding mounting plate 4 and the laser rangefinder 5 are fixedly installed by bolts. A through hole is provided in the center of the sliding mounting plate 4 for the bottom emitter of the laser rangefinder 5 to pass through. The laser emitter 10 and the second turntable 8 are fixedly connected by bolts. The above bolt connection method facilitates the disassembly, assembly, and maintenance of the laser rangefinder 5 and the laser emitter 10, ensuring that the equipment can maintain stable performance during long-term use, reducing measurement deviations caused by equipment installation problems, and improving the overall practicality of the device.

[0033] Example 2: A multi-functional bracket for precise positioning and measurement under high-voltage lines, please refer to... Figure 2 and Figure 5The high-precision adjustment component 9 also includes two fixed plates 903 fixedly connected to the bottom surface of the top plate 7. Both ends of the worm gear 902 are rotatably connected to the inner side of the fixed plates 903. The fixed plates 903 provide stable support for the worm gear 902, ensuring the stability of the meshing transmission between the worm gear 902 and the worm wheel 901. At the same time, the rotational self-locking characteristic of the worm gear 902 and the worm wheel 901 can improve the stability after angle adjustment, making the angle adjustment of the laser emitter 10 more precise and stable, and further ensuring the parallelism between the baseline and the line direction. A handle 904 is rotatably connected to the inner side of one of the fixed plates 903, and one end of the handle 904 is fixedly connected to one end of the worm gear 902. The outer side of the handle 904 is provided with anti-slip texture. The handle 904 makes it easy for the operator to rotate the worm gear 902. The anti-slip texture increases the friction of the hand, making the adjustment process more effortless and convenient, improving the efficiency of angle adjustment, reducing operation time, and reducing the risk of personnel exposure under high voltage lines.

[0034] Please refer to Figure 1 , Figure 3 and Figure 4 A threaded rod 15 is fixedly installed on the outer side of the sliding mounting plate 4. The threaded rod 15 can fix the sliding mounting plate 4 at any position on the guide rail 3 to prevent the laser rangefinder 5 from sliding after finding the fixed point, ensuring the stability of the positioning point and ensuring the accuracy of subsequent measurements. The inner side of the first turntable 2 is threadedly connected to the threaded rod 15. One end of the threaded rod 15 is fixedly connected to a hexagonal block 16, and the other end of the threaded rod 15 is fixedly connected to a pressing block 17. Rotating the hexagonal block 16 can make the pressing block 17 fit tightly against the base 1, realizing the relative fixation of the first turntable 2 and the base 1, avoiding the offset of the baseline caused by the rotation of the first turntable 2 during the measurement process, and ensuring the consistency of the measurement direction. The pressing block 17 is made of rubber. The inner side of the pressing block 17 adopts an arc surface that matches the shape of the base 1. The rubber material of the pressing block 17 can increase the friction with the base 1 and improve the fixing effect. At the same time, the arc surface design makes it fit more tightly with the base 1, further enhancing the stability of the first turntable 2 and reducing the measurement error caused by the shaking of the device.

[0035] The implementation principle of this application embodiment is as follows: When performing measurement work, the device is first placed under the high-voltage line at an approximate location. Then, the sliding mounting plate 4 slides along the guide rail 3. At this time, the laser rangefinder 5 emits lasers through its upper and lower ends. After accurately locating the point directly below the high-voltage line, the position is fixed by the threaded rod 15 on the outer side of the sliding mounting plate 4 to prevent slippage. Afterward, the staff marks the positioning point. Then, the entire device is moved to the positioning point. At this time, the base 1 is adjusted to a horizontal state by adjusting the three sets of circumferential array telescopic support legs 12 and the level bubble meter 13 on the first turntable 2. At the same time, the anti-slip texture of the ground end of the telescopic support legs 12 can enhance the stability of the device in complex terrain. After qualitative analysis, the first turntable 2 is rotated to adjust its direction. Then, the hexagonal block 16 is rotated to drive the threaded rod 15, causing the rubber extrusion block 17 to fit tightly against the base 1, fixing the position of the first turntable 2 and preventing the baseline from shifting. Afterward, the operator rotates the anti-slip handle 904, which, through the meshing transmission of the worm gear 902 and worm wheel 901 supported by the fixing plate 903, drives the laser emitter 10 on the second turntable 8 to rotate, projecting a baseline parallel to the line. The self-locking characteristics of the worm gear 902 and worm wheel 901 ensure angle stability. Finally, the signal transmitter 14 on the bottom of the base 1 works in conjunction with an external handheld rangefinder to complete the distance measurement on both sides along the vertical direction of the baseline, achieving accurate, efficient and safe measurement operations.
