Description

Technical Field

[0001] The utility model relates to the technical field of deep displacement detection, in particular to a guide wheel type omnidirectional displacement gauge array structure. Background Technique

[0002] In the engineering fields such as industrial and civil construction, road and bridge, and water conservancy, slope measurement technology can provide key geological and soil layer stability data, so it is crucial for disaster prevention and control and the safety of geotechnical engineering. As an angle measurement tool, the omnidirectional displacement gauge can accurately capture tiny changes, improve the monitoring accuracy and efficiency, enhance the ability of slope stability analysis and prediction, and improve the safety of the main project. Technological progress has enabled the omnidirectional displacement gauge to achieve monitoring automation and intelligence. Combining real-time data analysis and warning systems, it provides scientific decision-making support for the safety management of the main project, enhances the safety guarantee, and thus the application scenarios of the omnidirectional displacement gauge are very extensive.

[0003] Currently, the mainstream sensor similar to the omnidirectional displacement gauge and used for measuring deep displacement is the sectional displacement gauge. Before using such a sensor, the inclinometer tube must be buried in the measured soil body for a certain length. There are guide grooves that are perpendicular to each other inside the tube, serving as the positioning support and guide wheel track for the sensor. During measurement, the sensor measures the angle between the tube axis and the plumb line in sections inside the inclinometer tube, and determines the magnitude of the horizontal displacement by calculating the installation depth. The sectional displacement gauge forms a lantern shape by tightening metal sheets, so as to be fixed in the guide groove of the side inclinometer tube. However, there may be some problems in engineering applications: during the installation process, the sensor may encounter obstacles when being placed into the guide groove of the side inclinometer tube, resulting in failure to reach the predetermined depth, especially at the joint of two sections of the inclinometer tube, which is related to both the construction quality of the inclinometer tube and the fixed structure design of the sensor; after installation, due to the accidental failure of the tension structure of the sensor fixed structure, there may be a gap between it and the guide groove of the inclinometer tube, and it cannot be closely attached to the inclinometer tube, thus affecting the measurement accuracy. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Refer to Figure 1 and Figure 2 As shown in [drawings not specified in the original text] and [drawings not specified in the original text], an embodiment provided by the present invention is: a guide wheel type omnidirectional displacement gauge array structure, including a substrate 1. The substrate 1 serves as the support platform for the entire device, providing a stable foundation. The middle part of the front side of the substrate 1 is fixedly connected by threads to a detection module 2. The detection module 2 is located in the middle of the front side of the substrate 1 and is fixed by means of threaded connection to ensure the stability and reliability of the module during operation. The left part of the front side of the substrate 1 is fixedly connected by threads to a guide wheel mechanism 3, which can achieve omnidirectional movement and adapt to different working environments. The left and right sides of the substrate 1 are fixedly connected by threads to ball head universal joints 4, which allow the device to rotate flexibly in multiple directions, thereby increasing its movement range and flexibility. The side of the ball head universal joint 4 away from the substrate 1 is connected by installation to an extension rod 5, further expanding the operation range of the device and enabling it to perform precise displacement measurements in complex environments.

[0022] Refer to Figure 1 and Figure 2, the idler wheel mechanism 3 includes a spring shaft 34. The idler wheel mechanism 3 is a key part of the device, responsible for achieving the flexibility and stability of movement. The spring shaft 34 is fixedly connected to the front side of the detection module 2. As the core component of the idler wheel mechanism 3, the spring shaft 34 is fixed to the front side of the detection module 2, which can effectively absorb the impact force from the ground and protect the accuracy of the detection module 2. A spring 33 is sleeved outside the spring shaft 34, providing additional elastic support to keep the idler wheel 31 in good contact even on uneven surfaces. The spring shaft 34 is fixedly connected to an idler wheel bracket 32 on the outside, and the idler wheel bracket 32 is fixedly connected to an idler wheel 31 on the outside. The idler wheel bracket 32 is fixedly connected to the outside of the spring shaft 34 to ensure that the idler wheel 31 can rotate freely, thus realizing omnidirectional movement. A cover plate 36 is fixedly connected to the upper side of the spring shaft 34. Two studs 35 are provided on the outside of the substrate 1. The front and rear sides of the cover plate 36 are engaged with the studs 35. The cover plate 36 is fixed to the upper side of the spring shaft 34, playing a role in protecting the internal components. At the same time, by engaging with the studs 35 on the substrate 1, the stability of the overall structure is enhanced.

[0023] Refer to Figure 1 and Figure 2 , the substrate 1 is a long strip rectangle, which can effectively utilize space and provide sufficient installation positions for each component. Multiple mounting holes are provided on the surface of the substrate 1, allowing flexible installation of various components in different configurations, improving the adaptability of the design. The back mounting holes adopt a chamfering process to ensure the cleanliness of the back of the substrate 1. A strip hole is provided inside the substrate 1, which is used to install the communication line of the detection module 2, ensuring the rationality and safety of the line layout, avoiding line crossing and interference, improving the overall performance of the system, and reducing the weight of the substrate 1.

[0024] Refer to Figure 1 and Figure 2 , the detection module 2 is based on microelectromechanical system technology. The shell of the detection module 2 is made of aluminum alloy. Adopting microelectromechanical system technology, it has the characteristics of high precision and miniaturization, and is suitable for efficient measurement and data processing in a narrow space. The shell is made of aluminum alloy, which is not only light but also has excellent corrosion resistance and heat dissipation performance, and can work stably under various environmental conditions. The potting technology is adopted to meet the waterproof and dustproof requirements of the equipment.

[0025] Refer to Figure 1 and Figure 2, The extension rod 5 and the ball head universal joint 4 are connected by threads, ensuring the firmness and stability of the connection. At the same time, it is also convenient for disassembly and maintenance. The extension rod 5 has an angular range of 30° in the X-axis and Y-axis directions, and the length of the extension rod 5 is variable, enabling the displacement meter to adapt to different working environments and measurement requirements. The variable length design allows the extension rod 5 to be adjusted according to the actual application needs, further improving the applicability and flexibility of the device, and enabling effective displacement measurement in more complex spaces.

[0026] Working principle: During use, the sensor should be lowered into the inclinometer tube. However, conventional sensors use metal sheets tightened to form a lantern shape and are fixed by being stuck in the guide groove of the inclinometer tube. During the installation process, it may occur that the sensor cannot be lowered smoothly, resulting in the inability to reach the predetermined depth, especially at the joint of two sections of the inclinometer tube. The all-directional displacement meter array structure with guide wheels replaces the metal sheet of the conventional sensor with an embedded 440 stainless steel bearing guide wheel, which can effectively solve the problem of difficult lowering during the installation process.

[0027] After the installation is completed, the tensioning mechanism of the fixed structure of the conventional sensor may accidentally fail, and there may be a gap between it and the guide groove of the inclinometer tube, unable to fit tightly with the inclinometer tube, thus affecting the measurement accuracy. The guide wheel mechanism 3 of the all-directional displacement meter array structure with guide wheels also includes a pre-tightening mechanism, which consists of a connecting plate, a spring shaft 34, and a spring 33. This pre-tightening mechanism uses a spring 33 with an appropriate torque to provide the necessary pre-tightening force for the guide wheel bracket 32, ensuring that the two guide wheels 31 are evenly stressed, and solving the problems that uneven stress on the guide wheels 31 may cause the axis of the sensor to shift and there may be a gap between the sensor and the guide groove of the inclinometer tube after installation. Using a spring 33 with an appropriate torque as the core component of the pre-tightening mechanism to provide the necessary pre-tightening force for the guide wheel bracket 32, thereby improving the accuracy and reliability of the measurement.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
