A surface tilt monitoring apparatus

Abstract

This utility model discloses a surface tilt monitoring device, including a tilt sensor with a mounting assembly on top and a calibration assembly at the top of the tilt sensor. A rotating assembly and an adjusting assembly are located between the calibration assembly and the mounting assembly. The rotating assembly includes a first protrusion on the calibration assembly, and the mounting assembly has a support column opposite to the first protrusion. Through the coordinated operation of the rotating assembly and the adjusting assembly, using the rotating assembly as a fulcrum, the tilt angle of the calibration assembly in the X and Y axes can be adjusted separately using two vertically distributed adjusting components. Combined with a vertical level on the support, the tilt sensor can be quickly adjusted to a horizontal reference state, solving the problem of difficult calibration in existing equipment. Precise calibration ensures that the tilt sensor is initially in a horizontal state, avoiding measurement reference errors caused by installation deviations. Combined with the high-precision measurement capabilities of existing tilt sensors, the reliability of the overall monitoring data is further improved.

Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a surface tilt monitoring device. Background Technology

[0002] In production practices across numerous fields, including building construction, geological exploration, and the operation and maintenance of large equipment, precise monitoring of the surface tilt of the object under test is crucial. By tracking changes in the tilt angle of the object in real time through surface tilt monitoring equipment, it is possible to promptly detect whether its tilt posture exceeds a safe threshold, thereby providing critical data support for engineering safety and stable equipment operation.

[0003] In existing technologies, such as the tilt sensor disclosed in publication number CN118654637B, improvements have been made in optimizing tilt measurement accuracy. This sensor acquires tilt data through a tilt sensing module, and the measured data is transmitted via a communication cable to a separately configured data acquisition module, which then transmits the data externally. Its core advantage lies in the separate design of the tilt sensing module and the data acquisition module, coupled with a single-point fixing method. This effectively avoids the torsional interference caused to the tilt sensing module by uneven deformation due to temperature fluctuations in the data acquisition module, significantly reducing measurement errors. Simultaneously, the sensor has a real-time temperature monitoring function, which can further reduce the influence of ambient temperature on the tilt sensing module through temperature compensation, improving measurement accuracy.

[0004] However, these sensors have significant limitations in actual installation: they lack a convenient horizontal calibration mechanism, making it difficult to quickly adjust the sensor to a horizontal reference state. This not only increases the complexity of installation and debugging and prolongs the construction period, but also may lead to distortion of the subsequent tilt angle measurement reference due to the accumulation of initial horizontal deviation, ultimately affecting the reliability of the monitoring data.

[0005] Therefore, a surface tilt monitoring device that can efficiently achieve horizontal calibration is proposed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3This utility model provides a surface tilt monitoring device, including a tilt sensor 100, a mounting assembly 200, a calibration assembly 300, a rotation assembly 400, and an adjustment assembly 500. The mounting assembly 200 is located above the tilt sensor 100, the calibration assembly 300 is located at the top of the tilt sensor 100, and the rotation assembly 400 and the adjustment assembly 500 are located between the calibration assembly 300 and the mounting assembly 200. The rotation assembly 400 includes a first protrusion 410 on the calibration assembly 300, and a support column 420 opposite to the first protrusion 410 is provided on the mounting assembly 200. The bottom end of the support column 420 has a first groove 430 adapted to the first protrusion 410, and the first protrusion 410 is movably fitted into the inner cavity of the first groove 430. The rotation assembly 400 provides a rotation fulcrum for the calibration assembly 300, allowing the calibration assembly 300 to rotate flexibly around the support column 420, providing basic structural support for horizontal calibration and realizing flexibility in the calibration process.

[0026] It should be noted that the specific structure and working principle of the tilt sensor 100 mentioned above are consistent with the tilt sensor disclosed in the existing announcement number CN118654637B. It is existing technology, so it will not be described in detail in this technical solution.

[0027] The mounting assembly 200 includes an L-shaped mounting base 210 with mounting holes 220. The bottom of the mounting base 210 is fixedly connected to the top of the support column 420. The L-shaped mounting base 210 is suitable for various installation scenarios, making it easy to fix the device to the surface of the object being measured. The mounting holes 220 improve the flexibility of the installation position, and the fixed connection between the support column 420 and the mounting base 210 ensures the support stability of the rotating assembly 400.

[0028] The calibration assembly 300 includes a support 310 mounted on the top of the tilt sensor 100 and located below the mounting base 210. The support 310 is equipped with two mutually perpendicular levels 320. The bottom of the first protrusion 410 is fixedly connected to the support 310. The support 310 provides a mounting carrier for the levels 320 and the first protrusion 410. The two vertical levels 320 can display the horizontal status in the X and Y axis directions respectively, providing a visual reference for calibration operations and ensuring accurate calibration direction.

[0029] Among them, the level 320 is a cylindrical bubble level and is embedded in the upper surface of the support 310. The cylindrical bubble level can intuitively reflect the level state from multiple angles. The embedded installation method ensures that its relative position with the support 310 is stable, avoiding judgment errors caused by the offset of the level 320 during the calibration process.

[0030] Two adjustment components 500 are provided between the mounting base 210 and the support 310. The lines connecting the two adjustment components 500 and the support column 420 are respectively perpendicular to each other. The two vertically distributed adjustment components 500 can independently adjust the height of the support 310 in the X and Y axis directions, and together with the rotation component 400, achieve all-round horizontal calibration, avoiding the limitation of unidirectional adjustment.

[0031] The adjustment component 500 includes a second protrusion 510 movably mounted on the support 310, a bolt 520 passing through the mounting base 210, the surface of the bolt 520 being threadedly connected to the through portion of the mounting base 210, and a second groove 530 adapted to the second protrusion 510 being provided at the bottom end of the bolt 520. The second protrusion 510 is movably fitted into the inner cavity of the second groove 530. The threaded engagement between the bolt 520 and the mounting base 210 allows for precise adjustment of the height of the second protrusion 510 by rotation, thereby causing the support 310 to tilt. The movable fit between the protrusion 510 and the second groove 530 is adapted to the angle changes during the adjustment process, ensuring smooth transmission of the adjustment force.

[0032] The tops of the first protrusion 410 and the second protrusion 510 are both spherical, and the first groove 430 and the second groove 530 are both spherical grooves. The opening diameter of the first groove 430 is smaller than the diameter of the first protrusion 410, and the opening diameter of the second groove 530 is smaller than the diameter of the second protrusion 510. The spherical structure improves the flexibility of rotation and adjustment, and adapts to multi-angle calibration requirements. The design that the groove opening is smaller than the diameter of the protrusion can prevent the protrusion from falling out of the groove and ensure the stability of the structural connection.

[0033] The bottom of the second protruding post 510 is fixedly connected to a guide sleeve 540, and the inner cavity of the guide sleeve 540 is slidably connected to a guide bar 550. The bottom of the guide bar 550 is fixedly connected to the support 310. The sliding cooperation between the guide sleeve 540 and the guide bar 550 provides vertical support for the second protruding post 510, restricts its lateral displacement, ensures that the adjustment component 500 is stable and does not shake when subjected to force, and improves the adjustment accuracy.

[0034] The cross-sections of the inner cavities of the guide bar 550 and the guide sleeve 540 are both dovetail-shaped. The dovetail-shaped structure further restricts the relative rotation and lateral separation of the guide sleeve 540 and the guide bar 550, ensuring a stable and smooth sliding process and preventing the adjustment component 500 from being affected by shaking, thus maintaining calibration accuracy.

[0035] The working principle of this utility model is as follows:

[0036] Installation and calibration: First, fix the device to the surface of the object to be measured through the mounting hole 220 of the mounting base 210; at this time, the calibration component 300 is connected to 200 through the rotating component 400, and the two adjustment components 500 are distributed on both sides of the support column 420 and the line connecting them is perpendicular.

[0037] Observe the two vertical levels 320 on the support 310 to determine the current tilt direction of the support 310: if the level 320 in a certain direction is not horizontal, rotate the bolt 520 of the adjustment component 500 in the corresponding direction. The bolt 520 moves vertically through the thread engagement with the mounting base 210, pushing the second protrusion 510 to drive the guide sleeve 540 to slide along the guide bar 550, thereby causing the support 310 to rotate around the spherical fulcrum of the first protrusion 410 of the rotating component 400 until both levels 320 show horizontal, and the horizontal calibration of the tilt sensor 100 can be completed.

[0038] Monitoring: After calibration, the tilt sensor 100 uses the calibrated horizontal state as a reference to measure the surface tilt angle of the object in real time. Its measurement principle is the same as that of the existing tilt sensor with announcement number CN118654637B. It captures tilt angle changes through the internal sensing module and outputs monitoring data after processing. Since the tilt sensor 100 has been initially ensured to be in a horizontal reference by the calibration component 300, the influence of installation deviation on the measurement results is effectively avoided, and the accurate monitoring of the tilt state of the object is finally achieved.

[0039] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
