[0057] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0058] In the description of this utility model, it should be clarified that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence; the terms "vertical," "lateral," "longitudinal," "front," "back," "left," "right," "up," "down," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model, and do not mean that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation of this utility model.

[0059] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] like Figure 1-6As shown, this utility model embodiment provides a multifunctional measuring ruler for power grid construction projects, including a base plate 12, an angle plate 2, a first longitudinal ruler 6, a first transverse ruler 7, a lifting rod 8, a second longitudinal ruler 1, a support screw 10, and a second transverse ruler 5. The first longitudinal ruler 6 and the first transverse ruler 7 are mounted on the base plate 12. The second transverse ruler 5 is detachably connected to the base plate 12 by a first bolt 21, so as to be parallel or collinear with the first transverse ruler 7. The angle plate 2 is mounted on the base plate 12, and the central area of ​​the angle plate 2 is provided with an angle scale. The second longitudinal ruler 1 is hinged to the angle plate 2 by a rotating shaft 25 to cooperate with the angle plate 2 to measure angles. The lifting rod 8 passes through the center of the angle plate 2 and is used for height measurement. The first transverse ruler 7, the second longitudinal ruler 1, and the second transverse ruler 5 are all provided with support screws 10 to form a horizontal reference surface.

[0061] When the second horizontal ruler 5 is parallel to the first horizontal ruler 7, the two can move closer to each other or move further apart to clamp the cable and measure the wire diameter.

[0062] In this embodiment, the multifunctional measuring ruler for power grid construction projects includes core components such as a base plate 12, an angle plate 2, a first longitudinal ruler 6, a first transverse ruler 7, a lifting ruler rod 8, a second longitudinal ruler 1, a support screw 10, and a second transverse ruler 5. Its operation process needs to be combined with different measurement needs: When it is necessary to measure the angle, the second longitudinal ruler 1 can rotate around the pivot 25 on the angle plate 2. Since the angle plate 2 has an angle scale in the central area, the angle value can be read by the direction of the second longitudinal ruler 1 during the rotation, thus realizing the angle measurement; When measuring the height, the lifting ruler 8 passes through the center of the angle plate 2. By adjusting the support screws 10 on the first transverse ruler 7, the second longitudinal ruler 1 and the second transverse ruler 5, the rulers can be made to be in the same horizontal state. By adjusting the extension length of the lifting ruler 8, the height data can be directly obtained; When measuring the cable diameter, the second transverse ruler 5 is first connected to the base plate 12 by the first bolt 21 and adjusted to be parallel to the first transverse ruler 7. Then, by bringing the two transverse rulers closer to each other, the clamping action of the two can be used to obtain the cable diameter data; When it is necessary to extend the transverse measurement range, the second transverse ruler 5 can be adjusted to be collinear with the first transverse ruler 7. After being fixed by the first bolt 21, a longer transverse measurement distance can be achieved.

[0063] This embodiment of the multi-functional measuring ruler for power grid construction integrates multiple measurement functions such as angle, height, horizontal reference, cable diameter, and lateral length. It solves the problem of existing measuring tools having single functions and requiring frequent tool switching, and greatly improves the efficiency of measurement operations in power grid construction projects. The second horizontal ruler 5 and the base plate 12 are detachably connected, which can both clamp the cable in parallel and extend the measurement along the same line, flexibly adapting to different measurement scenarios. The setting of the support screw 10 ensures the formation of a horizontal reference plane and reduces errors caused by the non-horizontal measurement surface. Compared with the problem of traditional steel tape measure measurement relying on manual operation and large errors, this measuring ruler reduces the influence of human factors through structural design, improves measurement accuracy, and is especially user-friendly for new employees, reducing inconsistencies in measurement results.

[0064] The second horizontal ruler 5 has a mounting hole 20, and the base plate 12 has a screw hole 24 for connecting the first bolt 21.

[0065] In some embodiments, the second longitudinal ruler 1 is provided with a groove 3 extending through its length; the second transverse ruler 5 is fixed to an end of a mounting plate 11, and the bottom of the mounting plate 11 is provided with a slider 13 embedded in the groove 3, forming a sliding pair to adjust the distance between the two transverse rulers.

[0066] In this embodiment, the second longitudinal ruler 1 is provided with a groove 3 extending through its length, and the bottom of the mounting plate 11 fixed to the end of the second transverse ruler 5 is provided with a slider 13 embedded in the groove 3, forming a sliding pair. Its operation is mainly reflected in the stage of adjusting the distance between the two transverse rulers: when it is necessary to adjust the distance between the first transverse ruler 7 and the second transverse ruler 5 (whether measuring wire diameter or adapting to different measurement ranges), since the slider 13 is embedded in the groove 3, the second transverse ruler 5 can drive the slider 13 to slide along the length direction of the groove 3 through the mounting plate 11. During the sliding process, the groove 3 constrains the slider 13, ensuring that the second transverse ruler 5 always moves in a straight line and can stably maintain a parallel state with the first transverse ruler 7, avoiding deviation or tilting.

[0067] The sliding joint design of the multifunctional measuring ruler for power grid construction in this embodiment provides guidance for the movement of the second horizontal ruler 5. Compared with the adjustment method without guidance, it can effectively prevent the second horizontal ruler 5 from tilting during the movement, ensuring that it always remains parallel to the first horizontal ruler 7. This is especially important for cable diameter measurement. The clamping in the parallel state can more accurately reflect the actual diameter of the cable and reduce measurement errors caused by the tilt of the ruler. The slide groove 3 runs through the length of the second longitudinal ruler 1, providing sufficient travel space for spacing adjustment, which can adapt to cables of different diameters or different horizontal measurement needs. The cooperation between the slider 13 and the slide groove 3 makes the adjustment process smoother, avoiding jamming or shaking, and improving the ease of operation. Especially in the field power grid construction scenario, it can reduce repeated adjustments caused by unstable operation and improve work efficiency.

[0068] In some embodiments, the angle plate 2 is coaxially arranged with the base plate 12, and the lifting rod 8 passes vertically through the center of both; the zero mark of the second longitudinal ruler 1 coincides with the axis of the rotating shaft 25.

[0069] In this embodiment, the base plate 12 is a disc-shaped structure; the angle plate 2 is coaxially arranged with the base plate 12, the lifting rod 8 passes vertically through the center of the two, and the zero mark of the second longitudinal ruler 1 coincides with the axis of the rotating shaft 25. Its operation is closely related to the consistency of the benchmark for angle and height measurement: When measuring angles, since the angle plate 2 and the base plate 12 are coaxial, and the zero mark of the second longitudinal ruler 1 coincides with the axis of the rotating shaft 25, when the second longitudinal ruler 1 rotates around the rotating shaft 25, the zero mark is always aligned with the axis of the rotating shaft. At this time, the angle scale on the angle plate 2 is distributed with the rotating shaft as the center, and the direction of the second longitudinal ruler 1 can directly correspond to the accurate angle value, avoiding angle reading errors caused by zero mark offset; When measuring height, the lifting rod 8 passes vertically through the center of the angle plate 2 and the base plate 12, and the coaxiality of the two ensures the verticality of the lifting rod 8. In the vertical state, the extension length of the lifting rod 8 can truly reflect the height data, avoiding height measurement deviations caused by rod tilt; At the same time, the coaxial setting makes the force on each component more uniform, reducing structural deformation after long-term use.

[0070] This embodiment provides a precise reference for angle measurement by aligning the zero mark with the axis of the rotating shaft and coaxially designing the angle plate 2 and the base plate 12. This solves the problem of inaccurate angle readings caused by reference offset in some existing measuring tools. The lifting rod 8 vertically penetrates the center, ensuring the verticality reference for height measurement and making the height data more reliable. This is especially useful in measuring key parameters such as anchor bolt height and foundation top surface height in power grid construction, reducing errors. The coaxial design enhances the stability of the overall structure, reduces relative displacement between components, and extends the service life of the measuring ruler. Fourthly, the unified reference reduces the difficulty of reading for operators, eliminates the need for additional reference calibration, and improves measurement efficiency.

[0071] In some embodiments, the second horizontal ruler 5 has a plurality of first wire diameter grooves 18, and the first horizontal ruler 7 has a plurality of second wire diameter grooves 19 corresponding to the plurality of first wire diameter grooves 18. The first wire diameter grooves 18 and their corresponding second wire diameter grooves 19 are semi-circular grooves with equal radii. The plurality of first wire diameter grooves 18 have different diameters, and their diameters cover the standard cable size range.

[0072] In this embodiment, the second horizontal ruler 5 has multiple first wire diameter grooves 18, and the first horizontal ruler 7 has second wire diameter grooves 19 corresponding to the first wire diameter grooves 18. Both are semi-circular grooves with equal radii but different diameters, covering the standard cable size range. Its operation is mainly for cable diameter measurement: When measuring cable diameter, the second horizontal ruler 5 is first adjusted to be parallel to the first horizontal ruler 7. Then, the cable is placed between the two horizontal rulers. Based on the approximate diameter of the cable, the second horizontal ruler 5 is moved so that the cable is embedded in the corresponding first wire diameter groove 18 and second wire diameter groove 19. Since the grooves are semi-circular and the corresponding groove radii are equal, the cable is stably held by the two grooves. At this time, the wire diameter data can be read through the ruler scale. If the cable diameter is between two standard sizes, the approximate value can also be determined by the fit of the grooves.

[0073] This embodiment utilizes a semi-circular groove design to conform to the surface of a cylindrical cable, avoiding measurement deviations caused by cable rolling during traditional flat clamping and significantly improving the stability of wire diameter measurement. Multiple grooves of different diameters cover the standard cable size range, directly adapting to common cable models without additional calculations or conversions, thus improving measurement efficiency. The matching of corresponding grooves ensures symmetry when clamping the two horizontal rulers, avoiding errors caused by clamping position offsets. Fourthly, compared to the problem of skewness easily occurring when using traditional steel tape measures to measure cable diameter, this structure uses groove positioning, reducing the difficulty of operation. Even new employees can quickly master it, reducing errors caused by human error.

[0074] In some embodiments, the second longitudinal ruler 1 is provided with a scale, and the slider 13 is provided with a marker needle pointing to the scale.

[0075] In this embodiment, the second longitudinal ruler 1 is provided with a scale, and the slider 13 is provided with a marker needle pointing to the scale. Its operation mainly involves adjusting the distance between the two transverse rulers and reading the measurement: when it is necessary to adjust the distance between the first transverse ruler 7 and the second transverse ruler 5 (such as measuring wire diameter or adjusting the measurement range), the second transverse ruler 5 drives the slider 13 to slide along the groove 3 of the second longitudinal ruler 1 via the mounting plate 11. At this time, the marker needle on the slider 13 moves synchronously with the slider. Since the second longitudinal ruler 1 is provided with a scale, the scale value pointed to by the marker needle is the distance between the two transverse rulers. For example, when measuring the diameter of a cable, after the cable is clamped by the two transverse rulers, the scale value pointed to by the marker needle directly reflects the cable diameter; when adjusting the transverse measurement range, the total length after extension can also be quickly determined through the marker needle.

[0076] The combination of the marker needle and scale in this embodiment enables real-time reading of the spacing, eliminating the need for additional measuring tools and simplifying the operation process. The clear pointing of the marker needle avoids reading errors caused by direct observation of the ruler's edge, thus improving reading accuracy. In power grid construction, whether measuring cable diameter or the lateral spacing of foundation dimensions, data can be directly obtained through the scale, reducing data recording delays and error rates. Compared to traditional methods that require multiple comparisons of readings, this structure makes readings more intuitive, especially in low-light outdoor environments, reducing reading difficulty and improving work efficiency.

[0077] In some embodiments, a first right-angled triangular block 14 is provided on both sides of the first longitudinal ruler 6;

[0078] In one of the first right-angled triangle blocks 14, the right-angled sides are respectively attached to the first horizontal ruler 7 and the first vertical ruler 6, and the right-angled sides of the other first right-angled triangle block 14 are respectively attached to the second horizontal ruler 5 and the first vertical ruler 6.

[0079] In this embodiment, a right-angled triangular block 14 is provided on both sides of the first longitudinal ruler 6. The right-angled side of one right-angled triangular block 14 is respectively attached to the first transverse ruler 7 and the first longitudinal ruler 6, and the right-angled side of the other right-angled triangular block 14 is respectively attached to the second transverse ruler 5 and the first longitudinal ruler 6. Its operation is applicable to various transverse and longitudinal measurements: when measuring transverse or longitudinal dimensions, the right-angled triangular block 14 is attached to the first longitudinal ruler 6 and the corresponding transverse ruler (first transverse ruler 7 or second transverse ruler 5) through its right-angled side, forming a stable right-angled support structure. Due to the stability of triangles, this structure can limit the relative displacement between the first longitudinal ruler 6 and the transverse ruler, avoiding tilting or offset of the ruler due to external forces or long-term use. For example, when measuring the longitudinal length of the top surface of the foundation, the perpendicularity of the first longitudinal ruler 6 and the first transverse ruler 7 is maintained by the right-angled triangular block 14, ensuring that the measurement reference does not shift.

[0080] This embodiment achieves vertical positioning of the first longitudinal ruler 6 and the transverse ruler by fitting the right-angled sides of the first right-angled triangular block 14. This solves the problem of lost vertical reference caused by loose connection of some existing measuring rulers, ensuring the verticality reference for transverse and longitudinal measurements. The stability of the triangular structure enhances the overall ruler's resistance to deformation, reduces bending or displacement of the ruler due to collisions or compression, and extends its service life. The stable reference makes multiple measurement results more consistent and reduces errors caused by ruler shaking. Especially in the measurement of foundation dimensions, bolt spacing, and other high-precision requirements in power grid construction, it can improve data reliability. No additional verticality calibration is required, reducing preparation time and improving the continuity of measurement operations.

[0081] In some embodiments, the second longitudinal ruler 1 is provided with detachable second right-angled triangular blocks 15 on both sides, and the two second right-angled triangular blocks 15 are inserted into the insertion holes 17 of the angle plate 2 and the base plate 12 through the insertion rod 16;

[0082] In one of the second right-angled triangle blocks 15, the right-angled side is attached to the second horizontal ruler 5, the first horizontal ruler 7, and the second vertical ruler 1, respectively, and the right-angled side of the other first right-angled triangle block 14 is attached to the second horizontal ruler 5 and the second vertical ruler 1, respectively.

[0083] In this embodiment, detachable second right-angled triangular blocks 15 are provided on both sides of the second longitudinal ruler 1. The second right-angled triangular blocks 15 are inserted into the insertion holes 17 of the angle plate 2 and the base plate 12 via insert rods 16. The right-angled side of one second right-angled triangular block 15 is respectively attached to the second transverse ruler 5, the first transverse ruler 7, and the second longitudinal ruler 1, while the right-angled side of the other is respectively attached to the second transverse ruler 5 and the second longitudinal ruler 1. Its operation process is divided into three stages: installation, measurement, and disassembly. When in use, the insert rods 16 of the second right-angled triangular blocks 15 are inserted into the insertion holes 17 of the angle plate 2 and the base plate 12, so that the right-angled sides are respectively attached to the corresponding rulers. At this time, the second right-angled triangular blocks 15 provide support for the connection between the second longitudinal ruler 1 and the transverse ruler. During the measurement process, this structure restricts the relative displacement of the rulers and maintains the measurement reference. When not in use or when the measurement mode needs to be adjusted, the insert rods 16 can be pulled out from the insertion holes 17, and the second right-angled triangular blocks 15 can be removed.

[0084] This embodiment features a detachable design that allows the second right-angled triangular block 15 to be flexibly installed or removed according to measurement needs. When performing operations such as angle measurement that do not require strong support, it can be removed to reduce interference and improve operational flexibility. After installation, the right-angled edges fit together, further strengthening the vertical reference between the second longitudinal ruler 1 and the transverse ruler. Especially in long-term measurements or complex environments, this reduces errors caused by ruler swaying. The cooperation between the insertion rod 16 and the insertion hole 17 enables quick assembly and disassembly without complex tools, improving efficiency in adapting to different measurement scenarios. The support for the second longitudinal ruler 1 enhances its resistance to deformation, preventing bending due to excessive force and ensuring the long-term reliability of functions such as angle measurement, adapting to the complex environment of field operations in power grid construction.

[0085] In some embodiments, the inner wall of the insertion hole 17 is provided with a rough surface, and the surface of the insertion rod 16 has matching friction patterns; and / or,

[0086] The second right-angled triangular block 15 and the insertion rod 16 are an integrated structure.

[0087] In this embodiment, the inner wall of the insertion hole 17 is roughened, the surface of the insertion rod 16 has matching friction patterns, and / or the second right-angled triangular block 15 and the insertion rod 16 are an integral structure. Its operation is mainly reflected in the installation and fixing stage of the second right-angled triangular block 15: when installing the second right-angled triangular block 15, the insertion rod 16 is inserted into the insertion hole 17. Because the roughened surface of the inner wall of the insertion hole 17 and the friction patterns on the surface of the insertion rod 16 cooperate, a large frictional force is generated when they come into contact, making the insertion rod 16 stably fixed in the insertion hole 17 and not easily loosened. If it is an integral structure, there is no connecting gap between the second right-angled triangular block 15 and the insertion rod 16, and the force can be transmitted synchronously, avoiding support failure due to component separation. During the measurement process, this structure ensures that the second right-angled triangular block 15 always remains in contact with the ruler body and does not shift.

[0088] This embodiment increases the friction between the insertion rod 16 and the insertion hole 17 by combining the rough surface with the friction texture, solving the problem of easy loosening of traditional smooth contact surfaces. This ensures that the second right-angled triangular block 15 does not fall off or shift during the measurement process, guaranteeing the stability of the support and reference. The integrated structure eliminates the connection gap between the second right-angled triangular block 15 and the insertion rod 16, improving the overall load-bearing capacity of the structure, better resisting external impacts, and reducing component damage. The stable connection reduces accidental adjustments during the measurement process, preventing the second right-angled triangular block 15 from shifting due to vibration or collision, ensuring the continuous reliability of the measurement reference. No additional fixing devices (such as bolts) are required, which simplifies the structure, ensures the fixing effect, improves the efficiency of disassembly and assembly, and adapts to the needs of frequent switching measurement scenarios in power grid construction.

[0089] In some embodiments, a first level 22 is mounted on the top surface of the first transverse ruler 7, and a second level 9 is mounted on the top surface of the first longitudinal ruler 6, forming an orthogonal arrangement of the two levels.

[0090] In this embodiment, a first level 22 is installed on the top surface of the first horizontal ruler 7, and a second level 9 is installed on the top surface of the first vertical ruler 6, with the two levels arranged orthogonally. The operation mainly involves adjusting the horizontal reference plane: before measurement, the ruler body needs to be adjusted to a horizontal state using the support screw 10. At this time, the first level 22 and the second level 9 are observed. The first level 22 reflects the horizontal horizontal state, and the second level 9 reflects the vertical horizontal state. Due to their orthogonal arrangement, the overall levelness can be judged from both the horizontal and vertical directions. If the bubble of the first level 22 shifts, the support screw 10 of the first horizontal ruler 7 or the second horizontal ruler 5 is adjusted; if the bubble of the second level 9 shifts, the support screw 10 of the first vertical ruler 6 or the second vertical ruler 1 is adjusted until both level bubbles are centered, thus forming a horizontal reference plane. During the measurement process, the horizontal state can also be monitored in real time using the level instruments to avoid horizontal deviation caused by external interference.

[0091] This embodiment utilizes a dual-level orthogonal layout to simultaneously monitor both lateral and longitudinal levelness, solving the problems of traditional single-level instruments requiring multiple adjustments and struggling to comprehensively assess levelness, thus significantly reducing leveling time. The level instruments are directly mounted on the ruler, reflecting its actual levelness in real time, avoiding errors caused by indirect leveling with other tools and improving the accuracy of the leveling benchmark. Real-time monitoring detects level deviations during measurement, facilitating timely adjustments and reducing measurement errors caused by subsequent level changes. It is also more user-friendly for new employees, eliminating the need for experience-based leveling; adjustments can be made simply by observing bubble levels, lowering the operational threshold and ensuring that different personnel can quickly establish accurate leveling benchmarks, improving the consistency of measurement results.

[0092] In some embodiments, the top of the lifting ruler 8 is provided with an anti-detachment plate 4, the diameter of which is larger than the through hole of the angle plate 2; the ends of the first horizontal ruler 7 and the second horizontal ruler 5 are both provided with semi-circular relief grooves 23, which are adapted to the lifting ruler 8; and / or,

[0093] The bottom of the support screw 10 is a conical rubber head, and the top is a knob-type operating handle.

[0094] In this embodiment, the top of the lifting rod 8 is provided with an anti-detachment plate 4 (the diameter of which is larger than the through hole of the angle plate 2), and the ends of the first horizontal ruler 7 and the second horizontal ruler 5 are both provided with semi-circular clearance grooves 23 (adapted to the lifting rod 8), and / or the bottom of the support screw 10 is a conical rubber head and the top is a knob-type operating handle. Its operation process covers multiple functional aspects: when the lifting rod 8 is in use, the anti-detachment plate 4 can prevent it from completely detaching from the through hole of the angle plate 2, ensuring safe use; when the first horizontal ruler 7 and the second horizontal ruler 5 are adjusted to be close to the lifting rod 8, the semi-circular clearance grooves 23 are adapted to the lifting rod 8, avoiding interference between the ruler body and the rod body, and ensuring smooth spacing adjustment; when adjusting the support screw 10, the knob-type operating handle is easy to rotate manually, and the conical rubber head can stably contact the ground or measuring surface, making it less prone to slippage.

[0095] This embodiment uses an anti-detachment plate 4 to prevent the lifting rod 8 from falling off and being lost or injuring personnel, improving safety, especially in high-altitude measurements or field operations. The semi-circular clearance groove 23 solves the interference problem between the horizontal ruler and the lifting rod 8, allowing the two horizontal rulers to be closer to the center, expanding the applicability range for wire diameter measurements (such as small-diameter cables). The tapered rubber head increases the friction between the support screw 10 and the contact surface, preventing slippage and ensuring the stability of the ruler after leveling. The rubber material also reduces damage to the measuring surface. The knob-type operating handle facilitates manual adjustment without tools, improving the efficiency of leveling adjustment and adapting to field scenarios in power grid construction where auxiliary tools are unavailable. The overall structural design better meets actual operational needs, improving the practicality and reliability of the measuring ruler.
