Description

Technical Field

[0001] This application belongs to the field of building safety inspection technology, and in particular relates to an online inspection system for the safety of ancient buildings. Background Technology

[0002] Ancient buildings are precious heritages that carry historical and cultural value, and their structural safety is an essential aspect of cultural relic protection. With the continuous development of structural health monitoring technology, online safety monitoring systems have become an important means of routine protection for ancient buildings. By deploying sensors in key parts of the building, multiple structural parameters such as stress, displacement, and settlement can be collected in real time, providing data support for assessing the building's safety status.

[0003] The roof slab is a crucial load-bearing component in the structural system of ancient buildings. Its deformation directly reflects the overall stress and structural stability of the building. In particular, small deformations occurring early in the building are often early warning signs of structural deterioration and component loosening and failure, making them a key focus during safety inspections. Existing online safety monitoring systems for ancient buildings mostly employ technologies such as displacement sensing, tilt monitoring, or visual acquisition to obtain roof slab deformation data, ultimately outputting monitoring results to the maintenance team in the form of numerical reports and trend curves.

[0004] However, existing detection systems have problems in practical applications. They can only provide discrete monitoring values ​​and linear trends, failing to convert the minute deformation amplitudes of the roof slab into an intuitive spatial morphological display. Managers find it difficult to quickly grasp the surface unevenness, deformation gradient, and overall deformation trend of the roof slab through monitoring results. The roof slabs of ancient buildings often feature large spans, complex shapes, and diverse component types. Discrete data presentation methods cannot reconstruct the spatial distribution characteristics of deformation, leading to a high reliance on the professional experience of maintenance personnel for safety risk assessment. This makes it difficult to accurately locate local danger zones and accurately judge the cumulative development trend of minute deformations, necessitating improvements. Summary of the Invention

[0005] The purpose of this application is to provide an online safety monitoring system for ancient buildings that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide an online safety monitoring system for ancient buildings, including a wall and a panel installed on the wall, and further comprising: Mounting frame, installed on the wall; The detection frame is mounted on the plate and hinged to the mounting frame. A torsion spring is installed at the hinge point between the two. The detection enlargement structure is connected to the detection frame and the mounting frame at its two ends, respectively, to amplify the detection results. A feedback system, connected to the detection amplification structure, is used to receive and send data detected by the detection amplification structure; This also includes an alarm mechanism, which is connected to the detection expansion structure and feedback system, and can issue an alarm when a risk is detected.

[0007] The above-mentioned online safety inspection system for ancient buildings utilizes a hinged installation of the mounting frame and the inspection frame, along with a torsion spring at the hinge. This allows the inspection frame to rotate angularly in sync with the deformation of the ancient building's roof slab, achieving real-time transmission of roof slab deformation. The expanded inspection structure amplifies and transmits the minute deformation amplitude of the roof slab, transforming imperceptible micro-deformation into a directly identifiable displacement, thus solving the problem that existing inspection systems can only output discrete values ​​and cannot visually represent minute roof slab deformations.

[0008] Simultaneously, the feedback system can transmit the detected deformation data externally, achieving online synchronization of the detection status. The alarm mechanism can proactively issue a warning when the deformation reaches the risk threshold, eliminating the need for management personnel to rely on professional experience to assess risk from numerical curves, thus reducing the subjectivity and difficulty of risk assessment. Furthermore, in this application, the mounting frame and detection frame do not directly contact the wall or panel, but are installed at intervals using quick-release structures such as flange plates and bolts, creating a certain gap between the mounting frame / detection frame and the wall or panel.

[0009] Furthermore, it also includes: Support rods are vertically mounted on the mounting frame; The level has one end that can be extended and connected to the detection frame, and the other end that can be connected to the detection expansion structure; An extension rod is vertically mounted on a support rod, with one end connected to the other end of the detection enlargement structure; The change in the angle between the mounting frame and the detection frame can cause a change in the angle between the support rod and the extension rod.

[0010] The support rod is vertically mounted on the mounting frame, and the extension rod is vertically mounted on the support rod. Together with a retractable level, it transmits the angular deflection of the detection frame caused by the top plate to the detection expansion structure. The level helps calibrate the initial installation state of the detection frame, avoiding interference from installation angle deviations and reducing misjudgments due to installation errors, thereby improving detection accuracy. Changes in the angle between the mounting frame and the detection frame synchronously change the angles of the support rod and the extension rod, smoothly converting the vertical deformation of the top plate into the expansion displacement of the detection expansion structure. This provides a transmission basis for subsequent deformation amplification, avoiding losses or offsets during deformation transmission, ensuring that minute deformations are completely transmitted to the detection expansion structure, thus effectively enhancing the ability to capture early, minute deformations.

[0011] Furthermore: the detection amplification structure includes: The first enlarged section has one end rotatably connected to the level. The second enlarged section has one end rotatably connected to the extension rod; The second enlarged portion can be inserted into the first enlarged portion and can extend and retract along the first enlarged portion.

[0012] The detection enlargement structure adopts a telescopic structure in which the first enlargement part and the second enlargement part are interlocked. It can perform telescopic movements synchronously with the angle deflection of the detection frame, converting the small vertical deformation generated by the top plate into an amplified linear displacement, thereby realizing a visually magnified presentation of the deformation amplitude.

[0013] Meanwhile, the telescopic mechanism ensures smooth transmission, preventing interruptions in deformation transmission caused by jamming. It also adapts to deformation detection needs of varying magnitudes, capturing early, minute deformations as well as accommodating continuous monitoring after increased deformation, thus enhancing the device's applicability and detection adaptability. This structure provides structural support for visualizing minute deformations of the roof slab, solving the problem of difficult-to-observe minute deformations of ancient building roofs. This allows managers to quickly understand the deformation status, thereby assisting in risk assessment of ancient buildings.

[0014] Furthermore, the first enlarged portion includes: The housing has an internal cavity with a slider slidably connected inside, one end of which is connected to an extension rod. A linear guide, one end of which extends into the cavity inside the housing and is connected to the slider, and the other end is connected to the level. An adjusting plate is set inside the cavity and connected to the slider, and a guide post is provided at its bottom; The first contact plate is located at the bottom of the guide post; The second contact plate is located at the bottom of the housing; The first contact plate and the second contact plate are positioned corresponding to each other and connected to the alarm mechanism. When the first contact plate and the second contact plate come into contact, the alarm mechanism sounds an alarm.

[0015] The first enlarged section, through the sliding engagement of the slider and the cavity, combined with the directional transmission of the linear guide, guides the displacement transmitted by the level to the slider, ensuring the straightness and stability of the displacement transmission. The adjusting plate and guide post move synchronously with the slider, causing the first contact plate to gradually approach the second contact plate. When the deformation of the top plate reaches the set risk threshold, the first contact plate contacts the second contact plate and triggers the alarm mechanism to issue a warning, realizing the automatic triggering of the alarm in the risk state.

[0016] The structure described in this application can convert minute deformations of the roof slab into clear contact trigger signals through sliding transmission, allowing the risk status to be presented in an intuitive alarm form. This eliminates the need for personnel to analyze numerical curves to determine the risk level, reducing the difficulty of risk assessment and reliance on professional experience. It can promptly alert structural risks, preventing the continuous accumulation of minute deformations from leading to more serious structural deterioration, thereby reducing safety hazards in the roof slabs of ancient buildings.

[0017] Furthermore, the second enlarged portion includes: The connecting cylinder is located at the bottom of the slider and has a chamber inside. The adjusting plate is installed in the chamber, and one end of the guide post passes through the bottom of the cylinder. The elastic element includes a first spring, a second spring disposed in the cavity and on both sides of the adjusting plate, and a third spring disposed in the cavity; One end of the third spring is connected to the bottom of the slider, and the other end is connected to the bottom of the cavity.

[0018] The connecting cylinder contains a chamber and multiple sets of elastic components. Combined with the floating adjustment plate, this allows the slider to continue moving downwards along the cavity even after the alarm is triggered by contact between the first and second contact plates, ensuring the detection process is not interrupted by the alarm. The first and second springs provide elastic support to the adjustment plate from both sides, while the third spring provides additional elastic cushioning for the slider. This multi-elastic structure absorbs impacts during deformation transmission, preventing damage to components from rigid collisions and ensuring the smoothness of subsequent slider displacement.

[0019] The aforementioned structure enables the continued monitoring of deformation trends even after an alarm is triggered, solving the problem that existing detection devices cannot continue monitoring deformation development after an alarm is triggered. It can fully record the entire process of deformation from early warning to continuous deterioration, providing complete detection data for subsequent safety assessments and disease treatment, and further enhancing the comprehensiveness and reference value of the detection.

[0020] Furthermore, the second enlarged section also includes: The adjusting rod is vertically positioned at the bottom of the slider, and a swivel is provided on the end of the adjusting rod away from the slider; The resistance wire is placed at the bottom of the cavity and connected by a sliding plate. The resistance wire, adjusting contact rod, detection amplification structure, and feedback system are connected.

[0021] The adjusting rod moves synchronously with the slider, causing the swivel to slide on the surface of the resistance wire. This converts the mechanical displacement of the slider into a current change signal, which is then transmitted outward through the feedback system. The structure of this application converts the deformation of the top plate into a remotely acquireable electrical signal, thereby achieving online quantitative transmission of deformation data. Combined with the amplification effect of the detection magnification structure, it can convert the weak displacement corresponding to minute deformations into identifiable current changes, improving the detection sensitivity of minute deformations. The electrical signal transmission method facilitates centralized online monitoring at multiple points, eliminating the need for on-site personnel to read values, effectively improving the intelligence and remoteness of ancient building safety inspections. Managers can intuitively grasp the development of deformation through the feedback data, assisting in risk assessment, reducing errors in manual judgment, and providing data support for the routine management of ancient building structural safety.

[0022] Furthermore, the linear guide includes: The outer rod has one end rotatably connected to the level, and the other end is equipped with a first push plate; The inner rod has one end located inside the housing and connected to the slider, and the other end is provided with a second push plate; Limiting guide rods are provided between the first push plate and the second push plate, and multiple rods are provided. The housing is equipped with multiple linear bearings that are compatible with the limit guide rod.

[0023] In this application, the linear guide component employs an inner and outer rod structure with multiple limiting guide rods, working in conjunction with linear bearings on the housing. This provides multiple guiding constraints for the slider's movement, ensuring the straightness of the slider as it moves along the cavity and preventing skewing or jamming. The multiple guiding structure disperses the force during sliding, reducing jamming caused by unilateral friction. This effectively ensures that minute deformations are smoothly transmitted to the slider, preventing jamming from causing minute deformations to go undetected and improving the stability and accuracy of the detection. This structure effectively solves the problems of easy jamming during transmission and easy loss of minute deformations in existing detection devices, ensuring that early minute deformation signals can be completely captured, preventing jamming from affecting detection accuracy, and further improving the reliability of detection results and the operational stability of the detection system.

[0024] Furthermore, a first disc spring is provided between the outer rod and the first push plate, and a second disc spring is provided between the inner rod and the second push plate.

[0025] A first disc spring is installed between the outer rod and the first push plate, and a second disc spring is installed between the inner rod and the second push plate. When the transmission structure experiences jamming, the elastic deformation of the disc springs compensates for a certain amount of expansion and contraction displacement, preventing damage to the transmission structure due to rigid jamming. The elastic compensation of the disc springs maintains the continuity of detection even during short-term jamming, ensuring that the first and second enlarged sections maintain a certain relative displacement, preventing detection failure due to localized jamming. This structure improves the device's resistance to jamming, reduces the impact of transmission failures on the detection process, ensures the continuous effectiveness of deformation detection of ancient building roofs, reduces the possibility of missing minor deformations due to structural jamming, further improves the operational stability of the detection system, and provides reliable assurance for long-term online detection of ancient building roofs.

[0026] The beneficial effects of this application are: 1. This application, through the installation of the mounting frame and the detection frame, combined with the detection expansion structure, can amplify and transmit the minute deformation amplitude generated by the top plate, and transform the minute deformation that is not easily detected into a displacement that can be intuitively identified, thus solving the problem that the existing detection system can only output discrete values ​​and cannot intuitively present the minute deformation of the top plate. 2. By setting up a feedback system, the detected deformation data can be transmitted to the outside, realizing online synchronization of the detection status. The alarm mechanism can actively issue a warning when the deformation reaches the risk threshold, eliminating the need for managers to rely on professional experience to judge the risk from the numerical curve, thus reducing the subjectivity and difficulty of risk assessment. 3. By setting the first disc spring and the second disc spring, when the transmission structure jams, the elastic deformation of the disc spring itself can compensate for a certain amount of expansion and contraction displacement, avoiding rigid jamming that could damage the transmission structure. The elastic compensation effect of the disc spring can maintain the continuity of detection in a short-term jamming state, ensuring that the first enlarged part and the second enlarged part can still maintain a certain relative displacement, and will not directly cause detection failure due to local jamming.

[0031] The online safety monitoring system for ancient buildings provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0032] Example 1:

[0033] like Figures 1 to 7 As shown, embodiments of this application provide An online safety monitoring system for ancient buildings includes a wall 100 and a panel 110 installed on the wall 100, and further includes: Mounting frame 200 is installed on wall 100; The detection frame 300 is mounted on the plate 110 and hinged to the mounting frame 200. A torsion spring is installed at the hinge point between the two. The detection enlargement structure is connected at both ends to the detection frame 300 and the mounting frame 200, respectively, to amplify the detection results; Feedback system 400, connected to the detection amplification structure, is used to receive and send data detected by the detection amplification structure; It also includes an alarm mechanism 500, which is connected to the detection expansion structure and the feedback system 400 and can issue an alarm when a risk is detected.

[0034] In some embodiments of this application, such as Figure 1 As shown, the above-mentioned online safety inspection system for ancient buildings utilizes a hinged installation of the mounting frame 200 and the inspection frame 300. With the help of a torsion spring at the hinge, the inspection frame 300 can synchronously rotate in angle with the deformation of the ancient building's roof slab, achieving real-time transmission of roof slab deformation. The expanded inspection structure can amplify and transmit the minute deformation amplitude of the roof slab, transforming imperceptible micro-deformation into a directly identifiable displacement, thus solving the problem that existing inspection systems can only output discrete values ​​and cannot visually represent minute roof slab deformations.

[0035] Meanwhile, the feedback system 400 can transmit the detected deformation data to the outside, realizing online synchronization of the detection status. The alarm mechanism 500 can actively issue a warning when the deformation reaches the risk threshold, eliminating the need for management personnel to rely on professional experience to judge the risk from numerical curves, thus reducing the subjectivity and difficulty of risk assessment. In addition, in this application, the mounting frame 200 and the detection frame 300 do not directly contact the wall 100 and the plate 110, but are installed at intervals through quick-release structures such as flange plates and bolts, so that there is a certain gap between the mounting frame 200 and the detection frame 300 and the wall 100 and the plate 110.

[0036] Also includes: Support rod 210 is vertically mounted on mounting frame 200; The level 310 has one end that can be extended and connected to the detection frame 300, and the other end that can be connected to the detection expansion structure; An extension rod 220 is vertically mounted on a support rod 210, with one end connected to the other end of the detection enlargement structure; The change in the angle between the mounting frame 200 and the detection frame 300 can cause a change in the angle between the support rod 210 and the extension rod 220.

[0037] Support rod 210 is vertically mounted on mounting frame 200, and extension rod 220 is vertically mounted on support rod 210. Together with retractable level 310, they can transmit the angular deflection of detection frame 300 caused by the top plate to the detection expansion structure. Level 310 helps calibrate the initial installation state of detection frame 300, avoiding interference from installation angle deviations on the detection results, reducing misjudgments due to installation errors, and thus improving detection accuracy. Changes in the angle between mounting frame 200 and detection frame 300 synchronously change the angles of support rod 210 and extension rod 220, smoothly converting the vertical deformation of the top plate into the expansion displacement of the detection expansion structure. This provides a transmission basis for subsequent deformation amplification, avoiding losses or offsets during deformation transmission, ensuring that minute deformations are completely transmitted to the detection expansion structure, thereby effectively enhancing the ability to capture early minute deformations.

[0038] Example 2:

[0039] This application provides an online safety inspection system for ancient buildings. In addition to the above-mentioned technical features, the online safety inspection system for ancient buildings in this application also includes the following technical features.

[0040] like Figures 2 to 6 As shown, the detection amplification structure includes: The first enlarged part 600 has one end rotatably connected to the level 310; The second enlarged portion 700 has one end rotatably connected to the extension rod 220; The second enlarged portion 700 can be inserted into the first enlarged portion 600 and can extend and retract along the first enlarged portion 600.

[0041] In this embodiment, the detection enlargement structure adopts a telescopic structure in which the first enlargement part 600 and the second enlargement part 700 are nested together. It can perform telescopic movements synchronously with the angular deflection of the detection frame 300, converting the small vertical deformation generated by the top plate into an amplified linear displacement, thereby realizing an intuitive amplified presentation of the deformation amplitude.

[0042] Meanwhile, the telescopic mechanism ensures smooth transmission, preventing interruptions in deformation transmission caused by jamming. It also adapts to deformation detection needs of varying magnitudes, capturing early, minute deformations as well as accommodating continuous monitoring after increased deformation, thus enhancing the device's applicability and detection adaptability. This structure provides structural support for visualizing minute deformations of the roof slab, solving the problem of difficult-to-observe minute deformations of ancient building roofs. This allows managers to quickly understand the deformation status, thereby assisting in risk assessment of ancient buildings.

[0043] Example 3:

[0044] This application provides an online safety inspection system for ancient buildings. In addition to the above-mentioned technical features, the online safety inspection system for ancient buildings in this application also includes the following technical features.

[0045] As shown in Figure 3 to Figure 6 As shown, the first enlarged section 600 includes: The housing 610 has an internal cavity 611, and a slider 612 is slidably connected inside the cavity, one end of which is connected to the extension rod 220. The linear guide 620 has one end extending into the cavity 611 inside the housing 610 and connected to the slider 612, and the other end connected to the level 310. An adjusting plate 630 is disposed in the cavity 611 and connected to the slider 612, and a guide post 640 is provided at its bottom; The first contact plate 650 is located at the bottom of the guide post 640; The second contact plate 660 is disposed at the bottom of the housing 610; The first contact plate 650 and the second contact plate 660 are positioned corresponding to each other and connected to the alarm mechanism 500. When the first contact plate 650 and the second contact plate 660 come into contact, the alarm mechanism 500 issues an alarm.

[0046] In this embodiment, the first enlarged portion 600, through the sliding engagement of the slider 612 and the cavity 611, and in conjunction with the directional transmission of the linear guide 620, can guide the displacement transmitted by the level 310 to the slider 612, ensuring the straightness and stability of the displacement transmission. The adjusting plate 630 and the guide post 640 move synchronously with the slider 612, causing the first contact plate 650 to gradually approach the second contact plate 660. When the deformation of the top plate reaches the set risk threshold, the first contact plate 650 contacts the second contact plate 660 and triggers the alarm mechanism 500 to issue a warning, realizing the automatic triggering of the alarm in the risk state.

[0047] The structure described in this application can convert minute deformations of the roof slab into clear contact trigger signals through sliding transmission, allowing the risk status to be presented in an intuitive alarm form. This eliminates the need for personnel to analyze numerical curves to determine the risk level, reducing the difficulty of risk assessment and reliance on professional experience. It can promptly alert structural risks, preventing the continuous accumulation of minute deformations from leading to more serious structural deterioration, thereby reducing safety hazards in the roof slabs of ancient buildings.

[0048] Example 4:

[0049] This application provides an online safety inspection system for ancient buildings. In addition to the above-mentioned technical features, the online safety inspection system for ancient buildings in this application also includes the following technical features.

[0050] like Figures 3 to 6As shown, the second enlarged portion 700 includes: A connecting cylinder 710 is located at the bottom of the slider 612 and has a chamber 711 inside. An adjusting plate 630 is installed in the chamber 711, and one end of the guide post 640 passes through the bottom of the cylinder. The elastic element includes a first spring 720, a second spring 730 disposed in the cavity 711 and on both sides of the adjusting plate 630, and a third spring 740 disposed in the cavity 611. One end of the third spring 740 is connected to the bottom of the slider 612, and the other end is connected to the bottom of the cavity 611.

[0051] In this embodiment, a cavity 711 is provided inside the connecting cylinder 710, and multiple sets of elastic elements are installed. Combined with the floating configuration of the adjusting plate 630, this allows the slider 612 to continue moving downwards along the cavity 611 even after the first contact plate 650 contacts the second contact plate 660 and triggers an alarm. This ensures that the detection process is not interrupted by the alarm trigger. The first spring 720 and the second spring 730 provide elastic support to the adjusting plate 630 from both sides, and the third spring 740 provides additional elastic buffering for the slider 612. This multi-elastic structure absorbs the impact during deformation transmission, preventing damage to components from rigid collisions, while ensuring the smoothness of subsequent displacement of the slider 612.

[0052] The aforementioned structure enables the continued monitoring of deformation trends even after an alarm is triggered, solving the problem that existing detection devices cannot continue monitoring deformation development after an alarm is triggered. It can fully record the entire process of deformation from early warning to continuous deterioration, providing complete detection data for subsequent safety assessments and disease treatment, and further enhancing the comprehensiveness and reference value of the detection.

[0053] Furthermore, the second enlarged section 700 also includes: The adjusting rod 750 is vertically set at the bottom of the slider 612, and a sliding plate 760 is provided on the end of the adjusting rod 750 away from the slider 612; Resistance wire 770 is located at the bottom of cavity 611 and is slidably connected to plate 760; Among them, the resistance wire 770, the adjusting contact rod 750 are connected to the detection amplification structure and the feedback system 400.

[0054] The adjusting rod 750 moves synchronously with the slider 612, causing the swivel plate 760 to slide on the surface of the resistance wire 770. This converts the mechanical displacement of the slider 612 into a current change signal, which is then transmitted outward through the feedback system 400. The structure of this application converts the deformation of the top plate into a remotely acquireable electrical signal, thereby achieving online quantitative transmission of deformation data. Combined with the amplification effect of the detection magnification structure, it can convert the weak displacement corresponding to minute deformations into identifiable current changes, improving the detection sensitivity of minute deformations. The electrical signal transmission method facilitates centralized online monitoring at multiple points, eliminating the need for on-site personnel to read values, effectively improving the intelligence and remoteness of ancient building safety inspections. Managers can intuitively grasp the development of deformation through the feedback data, assisting in risk assessment, reducing errors in manual judgment, and providing data support for the routine management of ancient building structural safety.

[0055] Example 5:

[0056] This application provides an online safety inspection system for ancient buildings. In addition to the above-mentioned technical features, the online safety inspection system for ancient buildings in this application also includes the following technical features.

[0057] like Figures 3 to 6 As shown, the linear guide 620 includes: The outer rod body 621 has one end rotatably connected to the level 310, and the other end is provided with a first push plate 622; The inner rod 623 has one end located inside the housing 610 and connected to the slider 612, and the other end is provided with a second push plate 624; Limiting guide rods 625 are provided between the first push plate 622 and the second push plate 624, and multiple rods are provided; The housing 610 is equipped with multiple linear bearings 626 that are compatible with the limiting guide rod 625.

[0058] In this embodiment, the linear guide 620 employs an inner and outer rod body 621 with multiple limiting guide rods 625, working in conjunction with the linear bearing 626 on the housing 610. This provides multiple guiding constraints for the sliding of the slider 612, ensuring the straightness of the slider 612 as it moves along the cavity 611 and preventing it from skewing or jamming. The multiple guiding structure disperses the force during the sliding process, reducing the jamming caused by unilateral friction, effectively ensuring that minute deformations can be smoothly transmitted to the slider 612, preventing the failure to detect and identify minute deformations due to jamming, and improving the stability and accuracy of the detection. This structure effectively solves the problems of easy jamming during the transmission process and easy loss of minute deformations in existing detection devices, ensuring that early minute deformation signals can be completely captured, avoiding jamming from affecting the accuracy of the detection, and further improving the reliability of the detection results and the operational stability of the detection system.

[0059] Example 6:

[0060] This application provides an online safety inspection system for ancient buildings. In addition to the above-mentioned technical features, the online safety inspection system for ancient buildings in this application also includes the following technical features.

[0061] like Figures 3 to 6 As shown, a first disc spring 627 is provided between the outer rod 621 and the first push plate 622, and a second disc spring 628 is provided between the inner rod 623 and the second push plate 624.

[0062] In this embodiment, a first disc spring 627 is provided between the outer rod 621 and the first push plate 622, and a second disc spring 628 is provided between the inner rod 623 and the second push plate 624. When a jam occurs in the transmission structure, the elastic deformation of the disc springs compensates for a certain amount of expansion and contraction displacement, preventing damage to the transmission structure due to rigid jamming. The elastic compensation effect of the disc springs can maintain the continuity of detection under short-term jamming conditions, ensuring that a certain relative displacement is maintained between the first enlarged portion 600 and the second enlarged portion 700, preventing detection failure directly due to local jamming. The above structure improves the device's anti-jamming capability, reduces the impact of transmission failures on the detection process, ensures the continuous effectiveness of deformation detection of ancient building roofs, reduces the possibility of missing minor deformations due to structural jamming, further improves the operational stability of the detection system, and provides reliable assurance for long-term online detection of ancient building roofs.
