Description

Technical Field

[0001] The invention relates to the field of water conservancy project safety monitoring, and in particular to a tension line measurement auxiliary reading device. Background Art

[0002] The tension wire instrument is an important means of measuring the horizontal displacement of the dam. It uses a stainless steel wire stretched between two fixed reference points as the reference line. When the building is deformed and displaced under the coupling of external loads, its structure will produce a certain deviation value relative to this reference line. By measuring this value, the deformation of the building can be determined. At the same time, in order to further avoid the deflection problem caused by the deadweight of the metal wire, a number of floating devices (water tanks, floating boats) are often set up in the middle section of the wire body for support, so that the steel wire can move more freely. However, due to the wide layout range of the tension wire equipment and the poor environment, especially the dam top tension wire, which is buried under the asphalt concrete pavement and has poor ventilation, the tension wire equipment is in a high temperature and humid environment for a long time. Its poor service conditions will have an adverse effect on the measurement accuracy of the tension wire, usually the following two points: 1. Since the dam top tensioning line is located under the asphalt concrete pavement, it is often in a hot and humid environment in summer. The high temperature and hot steam will cause the equipment well road cover and the observation environment temperature in the well to be extremely high. A large amount of condensation water is easily generated on the reading scale, which seriously affects the use of manual measurement components of the tensioning line and limits the measurement accuracy of manual readings.

[0003] 2. The tensioning wire equipment is buried under the asphalt concrete pavement. The large height difference causes the line of sight between the surveyor and the measuring element to be too long, and the tensioning wire is not clear in the line of sight, thus affecting the measurement accuracy.

[0004] In response to the above two problems, the commonly used solution at this stage is to open the equipment road cover for heat dissipation and ventilation before observation, and then the observers enter the observation equipment well or lie on the road to perform measurement operations. However, this method is greatly affected by the meteorological environment of the day, especially in hot summer weather. The maximum temperature of the dam top tensioning line cover can reach 60°C, and the temperature in the equipment well can reach 50°C. In addition, the hot steam generated by leakage requires each observation to open the cover for 5-10 minutes for heat dissipation. However, the number of tensioning line equipment measurement points is large and the distribution range is wide. Manual measurement using this method is time-consuming and labor-intensive, with high labor costs, and there are certain safety hazards for observers.

[0005] The existing Chinese patent document CN116678340A proposes a tensioning line measuring device, which solves the problem of unclear tensioning line in the sight of observers due to the sight distance by installing an accessory device on the tensioning line device. This solution solves the influence of high temperature and long sight distance on observation accuracy during observation to a certain extent, but there are still the following problems that affect the observation accuracy of the tensioning line: Disadvantage 1: The above scheme adapts to the on-site environment only by changing the measurement method, which is somewhat one-sided. At present, manual monitoring of the tensioning line generally uses a magnifying glass to measure directly. The lighting angle and observation angle are difficult to control. The deviation of the lighting angle and observation angle will directly lead to measurement deviation. In addition, in the existing measurement method, the tensioning line is measured by a scale fixed on the main body of the tensioning line and the estimation of the measuring personnel. The line body and the scale are not on the same plane, which belongs to spatial measurement. The measuring personnel need to constantly adjust the lighting angle and observation angle, which takes a lot of time. In addition, there are large errors in the estimation of the measuring personnel, which is very easy to cause re-measurement events due to inaccurate readings, and its interference resistance is weak. Although the device of the above-mentioned Chinese patent document CN116678340A can be well combined with the principle of microscopes and can improve the observation efficiency of the tensioning line, when the tensioning line involves a large range, it is necessary to set this device at each measured point, and when the displacement of the tensioning line is large, there is a risk of affecting the freedom of the tensioning line body, resulting in abnormal measurement of the entire tensioning line device.

[0006] Disadvantage 2: Although the existing measurement scheme can shorten the problem of long observation sight distance by changing the observer's body shape, it has certain limitations. It has high requirements on the observer's body shape and cannot ensure that the observer's line of sight remains perpendicular to the tension line during the observation process. In addition, due to the differences in the visual angles between observers and the inconsistency of observation habits, it is very easy to have re-measurement incidents due to inaccurate readings. The device of the above-mentioned Chinese patent document CN116678340A, due to the lack of shortening processing for longer sight distances under special working conditions, cannot avoid the problem of unclear tension line body and reading scale in the field of view under special working conditions such as the dam top tension line, which limits the accuracy of tension line observation.

[0007] Disadvantage 3: Although the current observation scheme requires direct measurement and reading using a magnifying glass, etc. in accordance with relevant specifications, it does not meet the needs of certain special usage scenarios. For example, the dam top tensioning line is located below the asphalt concrete pavement. The observer needs to maintain his posture while using a magnifying glass to measure the tensioning line, which makes the observation operation extremely difficult and easily causes the observer to become unstable and injured, posing a safety hazard. Although the device of the above-mentioned Chinese patent document CN116678340A can be well combined with the principle of microscopes and can improve the efficiency of tensioning line observation, it needs to be installed on the measuring point of the tensioning line device. When the working environment of the measured point is poor, such as when the temperature and humidity in the measuring point equipment well are high, its image acquisition component is easily affected by condensed water, resulting in unclear imaging, which leads to insufficient accuracy of the observation data, and its ability to withstand external interference is weak. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a tension line measurement auxiliary reading device, which can assist observers in accurately obtaining tension line readings under special working conditions, and improve the observer's ability to withstand interference caused by the working environment of the tension line device when observing.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is: A tension line measurement auxiliary reading device, comprising a support structure and an observation structure; The support structure includes a main support rod, a secondary support rod and a measuring rod; The observation structure includes a sighting controller and a reading device; The measuring rod connects the main support rod and the auxiliary support rod to form an I-shaped support structure, which is used to be erected on the ground at the wellhead of the dam top tensioning line equipment; The observation structure is mounted on the measuring rod via a first guide rail located on the measuring rod, and the observation structure can be moved along the first guide rail under the alignment adjustment of the aiming controller.

[0010] The beneficial effects of the present invention are: providing an auxiliary reading device for tension line measurement, which realizes stable tension line reading measurement by erecting an I-shaped support structure formed by connecting a measuring rod to a main support rod and a secondary support rod on the ground of a wellhead of the dam top tension line equipment, and realizes alignment adjustment of the reading device and the tension line reading scale through the first guide rail and the aiming controller, effectively avoiding measurement errors caused by inconsistent observation angles. As a whole, it not only overcomes the problem of inaccurate observation data caused by excessive sight distance during observation operations due to height differences in special operating scenarios, but also overcomes the problem of insufficient accuracy of observation data due to the difficulty in always keeping the observer's line of sight vertical to the tension line, differences in line of sight between observers, and inconsistent observation habits.

[0013] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0014] Please refer to Figures 1 to 3 , a tension line measurement auxiliary reading device, comprising a support structure and an observation structure; The support structure includes a main support rod, a secondary support rod and a measuring rod; The observation structure includes a sighting controller and a reading device; The measuring rod connects the main support rod and the auxiliary support rod to form an I-shaped support structure, which is used to be erected on the ground at the wellhead of the dam top tensioning line equipment; The observation structure is mounted on the measuring rod via a first guide rail located on the measuring rod, and the observation structure can be moved along the first guide rail under the alignment adjustment of the aiming controller.

[0015] From the above description, it can be seen that the beneficial effects of the present invention are: providing an auxiliary reading device for tension line measurement, which realizes stable tension line reading measurement by erecting an I-shaped support structure formed by connecting the main support rod and the auxiliary support rod on the ground of the wellhead of the dam top tension line equipment, and realizes the alignment adjustment of the reading device and the tension line reading scale through the first guide rail and the aiming controller, which effectively avoids the measurement error caused by inconsistent observation angles. As a whole, it not only overcomes the problem of inaccurate observation data caused by too long sight distance during observation operation due to height difference in special working scenarios, but also overcomes the problem of insufficient accuracy of observation data caused by the difficulty of keeping the observer's line of sight and the tension line body vertical all the time, the differences in line of sight between observers, and the inconsistency of observation habits.

[0016] Furthermore, a second guide rail is provided on the main support rod; One end of the measuring rod connected to the main support rod can move along the second guide rail under the alignment adjustment of the aiming controller, so that the measuring rod and the tensioning line are located in the same longitudinal section.

[0017] From the above description, it can be seen that by setting a second guide rail on the main support rod, the measuring rod is allowed to move in the axial direction of the main support rod and adjusted through the aiming controller to ensure the consistency of the longitudinal section of the measuring rod and the tensioning wire device. This effectively avoids the deviation of the tensioning wire reading caused by height difference or angle problems, and further improves the measurement accuracy.

[0018] Furthermore, the observation structure also includes a leveling component; The leveling component is a circular level bubble and is arranged beside the reading device.

[0019] From the above description, it can be seen that by adding a leveling component, a simple and effective level adjustment method is provided, that is, the leveling component can ensure that the reading device and the tensioning line remain level, avoiding measurement errors caused by observation angle deviations, thereby improving the accuracy and consistency of the tensioning line readings.

[0020] Furthermore, both ends of the main support rod and the auxiliary support rod are provided with support legs; The support legs are height-adjustable.

[0021] From the above description, it can be seen that by setting support legs with adjustable heights, the overall device can flexibly adapt to the installation requirements of different ground environments, and the height-adjustable characteristics of the support legs enable the device to be stably erected in different construction scenarios, ensuring the reliability and applicability of the device; in addition, the adjustable height of the support legs can also cooperate with the leveling components to achieve the observation structure and the tensioning line and its reading scale to remain level, ensuring that the observer's line of sight is always perpendicular to the tensioning line body and its reading scale when measuring readings, thereby improving the standardization of the tensioning line observation operation and the accuracy of the data results.

[0022] Furthermore, the observation structure also includes an amplification component; The magnifying component is integrated with an adjustable focusing function and is arranged at the reading device, and is used to focus and magnify the reading of the reading device.

[0023] From the above description, it can be seen that the introduction of the magnifying component enhances the observation effect of the reading device, which is especially suitable for smaller reading scales or occasions with dim ambient light; at the same time, the magnifying component integrates an adjustable focus function to ensure the clarity of the reading and reduce the reading error caused by blur.

[0024] Furthermore, the observation structure also includes an imaging window; The imaging window is arranged directly above the reading device, and is used for imaging and displaying the magnified reading of the reading device.

[0025] From the above description, it can be seen that the combination of the imaging window and the magnifying component can more effectively display the magnified image of the tension line reading scale; at the same time, the setting of the imaging window enables the observer to directly view the clear magnified image through the window, which greatly improves the reading efficiency and accuracy.

[0026] Furthermore, the imaging window is a window structure designed with anti-condensation material.

[0027] From the above description, it can be seen that the imaging window structure designed with anti-condensation material can effectively prevent the condensation water generated by the high humidity environment in the equipment well from affecting the field of view, and this design of the imaging window can ensure that the observation results are not affected under harsh environmental conditions, thereby enhancing the reliability and stability of the device.

[0028] Furthermore, the amplifying component and the imaging window are optical or digital based amplifying and imaging devices.

[0029] From the above description, it can be seen that by using optical or digital magnification and imaging equipment to enhance the imaging quality of the tension line and the reading scale, higher quality observation images can be provided. This enhancement effect helps to improve the accuracy of the readings, especially when the viewing distance is far or the lighting conditions are poor, making the observation clearer and more accurate.

[0030] Furthermore, the auxiliary support rod is connected to one end of the measuring rod through a folding bearing.

[0031] From the above description, it can be seen that the auxiliary support rod and one end of the measuring rod are connected by a folding bearing, which has a more flexible and convenient structural design, and is convenient for assembly and disassembly in different working environments; at the same time, the folding design makes the device more convenient during transportation and storage, and does not affect its stability during use.

[0032] Furthermore, the folding bearing is arranged in the middle part of the auxiliary support rod.

[0033] From the above description, it can be seen that a folding bearing is arranged in the middle part of the secondary support rod, so that the folding function of the device is more stable and can effectively support the disassembly and assembly function of the device; this design makes the device more convenient and reliable, suitable for various work scenes that require quick construction and dismantling, and improves the practicality of the device.

[0034] The invention provides a tension line measurement auxiliary reading device, which is suitable for special scenarios, especially the dam top tension line observation and measurement scenario at the equipment well in the hot and rainy season in summer. The following is a specific description in combination with a specific embodiment: Please refer to Figures 1 to 3 , Embodiment 1 of the present invention is: A tension line measurement 3 auxiliary reading device 22, such as Figure 1 As shown, it includes a supporting structure 1 and an observation structure 2.

[0035] like Figures 1 to 3, wherein the support structure 1 includes a main support rod 11, a secondary support rod 12 and a measuring rod 13, and the observation structure 2 includes an aiming controller 21 and a reading device 22. In this embodiment, the measuring rod 13 connects the main support rod 11 and the secondary support rod 12 to form an I-shaped support structure 1, which can be erected on the ground of the equipment wellhead of the dam top tensioning line 3, and during the erection process, the measuring rod 1 can be set at the center position just above the equipment wellhead, and the axial direction of the measuring rod 13 is consistent with the installation direction of the tensioning line 3; at the same time, the observation structure 2 can be installed on the measuring rod 13 by moving along the axial direction of the measuring rod 13 through the first guide rail located on the measuring rod 13, which is not shown in the figure, and the observation structure 2 can be moved along the first guide rail under the alignment adjustment of the aiming controller 21 so that the reading device 22 is aligned with the reading scale 4 of the tensioning line 3.

[0036] That is, in the present embodiment, by erecting an I-shaped support structure 1 formed by connecting the main support rod 11 and the auxiliary support rod 12 by a measuring rod 13 on the ground of the equipment wellhead of the dam top tensioning line 3, a stable reading measurement of the tensioning line 3 is achieved, and by making the installation direction of the measuring rod 13 consistent with that of the tensioning line 3, the stability and accuracy of the device are ensured, and the alignment adjustment of the reading device 22 and the reading scale 4 of the tensioning line 3 is achieved by cooperating with the aiming controller 21 through the first guide rail, thereby effectively avoiding measurement errors caused by inconsistent observation angles. As a whole, it not only overcomes the problem of inaccurate observation data caused by long sight distance during observation due to height difference in special operation scenarios, but also overcomes the problem of insufficient accuracy of observation data due to the difficulty in always keeping the line of sight of the observer and the line body of the tensioning line 3 vertical, the differences in line of sight between observers, and the inconsistency of observation habits.

[0037] At the same time, in this embodiment, a second guide rail not shown in the figure is provided on the main support rod 11, and the end of the measuring rod 13 connected to the main support rod 11 can be moved along the second guide rail under the alignment adjustment of the aiming controller 21, so that the measuring rod 13 and the tensioning line 3 are located in the same longitudinal section.

[0038] That is, by setting the second guide rail on the main support rod 11, the measuring rod 13 is allowed to move in the axial direction of the main support rod 11, and adjusted by the aiming controller 21, so as to ensure the consistency of the longitudinal section of the measuring rod 13 and the tensioning wire 3 device, which effectively avoids the reading deviation of the tensioning wire 3 caused by height difference or angle problem, and further improves the measurement accuracy. It is worth noting that the first guide rail and the second guide rail in this embodiment are both electric guide rails to achieve smooth movement.

[0039] Please refer to Figure 3 , Embodiment 2 of the present invention is: A tension line measurement auxiliary reading device 22, based on the above embodiment 1, in this embodiment, as Figure 3As shown, the observation structure 2 further includes a leveling component 23 .

[0040] In this embodiment, the leveling component 23 is a circular level bubble and is arranged next to the reading device 22. By adding the leveling component 23, a simple and effective level adjustment method is provided, that is, the leveling component 23 can ensure that the reading device 22 and the tensioning line 3 remain level, avoiding measurement errors caused by observation angle deviations, thereby improving the accuracy and consistency of the readings of the tensioning line 3.

[0041] Meanwhile, in the present embodiment, both ends of the main support rod 11 and the auxiliary support rod 12 are provided with support legs 14 which are detachably mounted on the ground of the wellhead of the dam top tensioning line 3 equipment, and the height of the support legs 14 is adjustable.

[0042] That is, by providing support legs 14 with adjustable heights, the overall device can flexibly adapt to the installation requirements of different ground environments, and the height-adjustable characteristics of the support legs 14 enable the device to be stably erected in different construction scenarios, thereby ensuring the reliability and applicability of the device; in addition, the height-adjustable support legs 14 can also cooperate with the leveling assembly 23 to achieve the observation structure 2 and the tensioning line 3 and its reading scale 4 to remain level, ensuring that the observer's line of sight is always perpendicular to the tensioning line 3 and its reading scale 4 when measuring readings, thereby improving the standardization of the tensioning line 3 observation operation and the accuracy of the data results.

[0043] In addition, in this embodiment, Figure 3 As shown, the auxiliary support rod 12 is connected to one end of the measuring rod 13 through a folding bearing 121. That is, the auxiliary support rod 12 and one end of the measuring rod 13 are connected through the folding bearing 121, which has a more flexible and convenient structural design, and is convenient for assembly and disassembly in different working environments; at the same time, the folding design makes the device more convenient during transportation and storage, and does not affect its stability during use.

[0044] The folding bearing 121 is arranged in the middle of the auxiliary support rod 12, which makes the folding function of the device more stable and can effectively support the disassembly and assembly function of the device. This design makes the device more convenient and reliable, suitable for various work scenes that require rapid construction and dismantling, and improves the practicality of the device.

[0046] That is, in this embodiment, the introduction of the magnifying component enhances the observation effect of the reading device 22, which is particularly suitable for smaller reading scales 4 or occasions with dim ambient light; at the same time, the magnifying component integrates an adjustable focus function to ensure the clarity of the reading and reduce the reading error caused by blur.

[0047] At the same time Figure 3 The observation structure 2 further includes an imaging window 24 , which is disposed directly above the reading device 22 and is used for imaging and displaying the magnified reading of the reading device 22 .

[0048] That is, the imaging window 24 is combined with the magnifying component to more effectively display the magnified image of the tensioning line 3 reading scale 4; at the same time, the setting of the imaging window 24 enables the observer to directly view the clear magnified image through the window, which greatly improves the reading efficiency and accuracy. In this embodiment, the imaging window 24 is a window structure designed with anti-condensation material, which can effectively prevent the condensation water generated by the high humidity environment in the equipment well from affecting the field of view, and this design of the imaging window 24 can ensure that the observation results are not affected under harsh environmental conditions, thereby enhancing the reliability and stability of the device.

[0049] At the same time, the magnifying component and the imaging window 24 are based on optical or digital magnifying and imaging devices, and the imaging quality of the tensioning wire 3 and the reading scale 4 is enhanced by using optical or digital magnifying and imaging devices. That is, by enhancing the imaging quality of the tensioning wire 3 and the reading scale 4 by optical or digital means, a higher quality observation image can be provided, and this enhancement effect helps to improve the accuracy of the reading, especially in the case of a long viewing distance or poor lighting conditions, making the observation clearer and more accurate.
