[0002] Borehole stress gauges are important instruments for monitoring the internal stress state of rock formations and are widely used in safety monitoring in mines, tunnels, and other underground projects. By measuring stress changes, engineers can predict and prevent geological disasters such as rock collapse and mine tremors. However, the measurement accuracy of borehole stress gauges depends heavily on their installation angle in the borehole. Traditional methods of installing borehole stress gauges often fail to precisely control the gauge's rotation angle, resulting in errors in the measured data and thus affecting the accuracy of project safety assessments.

[0003] Existing borehole stress gauge installation systems typically rely on manual adjustments and empirical judgment. Specifically, due to the complex deep-hole environment, traditional strain gauge installation often relies on experience and simple mechanical devices for angle adjustment, which cannot guarantee that the strain gauge's rotation angle within the hole is exactly the same as the design requirements. This can lead to deviations in the measured stress data, affecting project safety assessments. Furthermore, traditional installation methods require delicate operations in complex environments and rely on experienced technicians. The installation process is time-consuming and complex, increasing labor costs and operational risks.

[0004] Therefore, there is a technical problem in the prior art that the installation of the borehole stress gauge is highly complicated. Summary of the Invention

[0007] In a second aspect, the present invention provides a method for installing a borehole stress gauge, the method comprising: Inserting the borehole stress gauge into the mounting hole to a predetermined depth through a connection system; wherein one end of the borehole stress gauge is connected to one end of the stress gauge angle detection device, and the other end of the stress gauge angle detection device is connected to the connection system; The borehole stress gauge is rotated to a predetermined rotation angle by rotating the connection system; wherein, during the rotation of the connection system, the borehole stress gauge is also driven to rotate, and the stress gauge angle detection device is capable of detecting the rotation angle of the borehole stress gauge and sending a detection signal representing the rotation angle to a data monitoring device capable of communication with the data monitoring device; When it is determined that the borehole stress gauge has been rotated to a predetermined rotation angle based on the rotation angle displayed by the data monitoring device, the rotation is stopped.

[0008] Beneficial effects: The present invention realizes precise control and real-time monitoring of the installation process of the borehole stress gauge through a stress gauge angle detection device, a connection system and a data monitoring device.

[0012] In this embodiment, one end of the stress gauge angle detection device can provide an interface for connecting to the drilling stress gauge. The interface can be a standardized mechanical interface, for example, a threaded interface or a snap-on interface. Specifically, using a threaded connection method, the stress gauge angle detection device can be firmly connected to the drilling stress gauge by rotation. This connection method has high reliability and strong vibration resistance. The snap-on interface can use a mechanical snap or a pin to achieve quick connection and separation. The interface can also be a self-locking quick connector or a magnetic interface. The interface can also be a flexible connection interface, for example, it can be a universal joint.

[0013] In this embodiment, the stress gauge angle detection device may include an angle detection device body, which may be a housing. The housing may be provided with an angle detection module, a communication module, and a power supply module. The angle detection module may detect the rotation angle of the borehole stress gauge within the mounting hole and generate a corresponding detection signal during the installation of the borehole stress gauge; the communication module may transmit the detection signal generated by the angle detection module to a target device. The target device may be a data monitoring device 300 or a communication relay device 400. The power supply module may provide energy for the angle detection module and the communication module.

[0014] In some embodiments, the angle detection module may further include a first detection submodule, a second detection submodule, and a generation module. The first detection submodule and the second detection submodule may be integrated into a single device. The first detection submodule may be configured to obtain acceleration information. The second detection submodule may be configured to obtain angular velocity information. The generation module may calculate and generate accurate rotation angle information based on the acceleration and angular velocity information.

[0015] In some embodiments, the angle detection module may also be an angle detection module based on a tilt sensor. Specifically, the angle detection module may further include a tilt detection submodule and a tilt calculation module. The tilt detection submodule may be used to measure changes in the direction of gravity, and the tilt calculation module may calculate and generate corresponding rotation angle information based on the detected gravity direction change signal. The tilt detection submodule and the tilt calculation module may also be integrated into a single device. The angle detection module may also be an angle detection module based on an optical encoder or an angle detection module based on an inductive sensor, etc.

[0016] A connection system is connected to the other end of the strain gauge angle detection device and is configured to be at least partially disposed within the mounting hole during installation of the borehole strain gauge, capable of extending the borehole strain gauge to a predetermined depth within the mounting hole and rotating the borehole strain gauge to a predetermined rotation angle.

[0017] In this embodiment, the connection system may be comprised of multiple straight rods. It is understood that these multiple straight rods can be connected to form a longer straight rod. For example, the length can be 15 meters, 20 meters, or 25 meters, etc. It is also understood that in this case, the length of the connection system is adjustable and can be adjusted to suit the depth of the mounting hole. In some embodiments, the connection system may also be comprised of a telescopic rod. This telescopic rod may be composed of multiple sections of telescopic rods, and its length can be adjusted through a telescoping mechanism to accommodate mounting holes of varying depths. In some embodiments, the connection system may be a segmented articulated rod system. Specifically, the connection system may be a segmented articulated rod system. This system is comprised of multiple articulated rod segments, each connected by a hinge or universal joint. In some embodiments, the connection system may also be a motorized rod system. Specifically, this system may be a motorized rod system. This system has a built-in motorized device that allows for electrically adjustable length and angle of the system, enabling automated installation.

[0018] A data monitoring device is configured to at least be communicatively connected to the strain gauge angle detection device to obtain the detection signal, and based on the detection signal, at least display the rotation angle of the corresponding drilling strain gauge.

[0019] In this embodiment, the data monitoring device may be configured with a communication module, through which the data monitoring device may be connected to the stress gauge angle detection device in a wired or wireless communication manner. The data monitoring device may also be connected to a communication relay device in a wireless communication manner, and the communication relay device is also connected to the stress gauge angle detection device in a wireless communication manner. The communication relay device performs communication relaying on the detection signal generated by the stress gauge angle detection device to adapt to deeper mounting holes. Specifically, the communication module in the data monitoring device may be a physical connection line (such as a USB, Ethernet cable, etc.) that directly communicates with the stress gauge angle detection device. This method may be suitable for shallow hole scenarios. The communication module in the data monitoring device may also be a communication module that supports wireless communication methods (such as Wi-Fi, Bluetooth, LoRa, etc.).

[0020] In one specific embodiment, the communication module configured in the strain gauge angle detection device and data monitoring device can utilize a UWB (ultra-wideband) communication module. Specifically, this communication module utilizes UWB (Ultra-Wideband) technology, which transmits short pulse signals across the ultra-wideband spectrum to achieve high-precision temporal resolution and data transmission. UWB communication, with its extremely high bandwidth and low power consumption, enables high-precision positioning and data transmission over short distances. This communication method is suitable for penetrating complex geological formations in deep borehole environments, ensuring stable data transmission.

[0021] In this embodiment, the data monitoring device is further configured with a processing module and a display module. The processing module can analyze the received detection signal to restore it to rotation angle information, and the display module can display the rotation angle information to the user.

[0022] The processing module can analyze and process the detection signals received by the communication module to obtain rotation angle information. The display module can display the rotation angle information generated by the processing module to the user in graphical or numerical form. The display module can adopt various display modes, such as liquid crystal display (LCD), organic light-emitting diode display (OLED), or electronic ink display (E-ink). The display module can provide a clear and easy-to-read interface. Specific display content includes but is not limited to numerical display of the rotation angle, angle change trend chart, real-time status indication, etc.

[0023] In one specific implementation, a processing module decodes the received UWB signal and generates precise rotation angle information through algorithmic processing. The processing module also performs corrections on the received data to ensure accuracy and reliability in the complex environment of deep holes. A display module presents the rotation angle information generated by the processing module to the user in graphical or numerical form.

[0024] The data monitoring device can be a handheld smart terminal that can wirelessly connect to the strain gauge angle detection device and receive detection signals from the strain gauge angle detection device. The data monitoring device can also be a portable tablet computer or an industrial data monitoring terminal.

[0025] In this embodiment, by integrating a strain gauge angle detection device, a connection system, and a data monitoring device, precise installation and real-time angle monitoring of borehole strain gauges in deep-hole environments are achieved. The strain gauge angle detection device accurately detects the rotation angle of the borehole strain gauge within the installation hole and generates a corresponding detection signal. Through the connection system, the strain gauge is smoothly inserted to the predetermined depth and precisely rotated to the predetermined angle, ensuring the accuracy of the measured data. The data monitoring device receives and displays rotation angle information in real time, making the installation process more controllable and accurate, significantly improving the installation efficiency and measurement reliability of the borehole strain gauge, and reducing the errors and complexity of manual operation.

[0026] like Figure 2 As shown, in some embodiments, the strain gauge angle detection device includes: An angle detection module is configured to detect a rotation angle of the borehole stress gauge in the installation hole and generate a corresponding detection signal during the installation process of the borehole stress gauge.

[0027] In this embodiment, the angle detection module may further include a first detection submodule, a second detection submodule, and a generation module. The first detection submodule and the second detection submodule may be integrated into a single device. The first detection submodule may be used to obtain acceleration information. The second detection submodule may be used to obtain angular velocity information. The generation module may calculate and generate accurate rotation angle information based on the acceleration information and angular velocity information.

[0028] In this embodiment, the first detection submodule may be an accelerometer, for example, a three-axis accelerometer. The three-axis accelerometer can measure acceleration information along the X, Y, and Z axes, and infer the strain gauge's tilt angle and posture by detecting changes in the direction of gravity. The second detection submodule may be a gyroscope, for example, a three-axis gyroscope. The three-axis gyroscope can measure the angular velocity information of the strain gauge within the mounting hole, capable of capturing the strain gauge's rotational motion and thus recording changes in its rotation angle. The generation module is pre-configured with a corresponding generation algorithm that can generate corresponding rotation angle information based on the acceleration information and angular velocity information. Specifically, the generation module may be pre-configured with a Kalman filter algorithm for fusing the measurement data from the accelerometer and gyroscope to calculate accurate rotation angle information. The accelerometer measures the strain gauge's tilt angle information relative to the direction of gravity, but this data may be subject to interference in the presence of motion acceleration (such as during rotation). Therefore, the accelerometer alone cannot be relied upon to obtain angle information. The gyroscope measures the angular velocity of the strain gauge. By integrating the angular velocity signal over time, the strain gauge's rotation angle can be determined. However, gyroscope data may contain cumulative errors (drift), which accumulate over long periods of measurement. Therefore, by establishing a state equation for the strain gauge, the angle obtained by integrating the gyroscope's angular velocity is used as the system state estimate, and the accelerometer angle is used as the measurement update. The filter continuously adjusts the angle estimate, ultimately achieving an accurate and stable rotation angle.

[0029] A communication module is configured to transmit the detection signal generated by the angle detection module to a target device.

[0030] In this embodiment, the communication module can be a physical connection line (such as USB, Ethernet cable, etc.) to directly communicate with the data monitoring device. This method is suitable for shallow hole scenarios. The communication module 102 can also be a communication module that supports wireless communication methods (such as Wi-Fi, Bluetooth, LoRa, etc.).

[0031] In a specific embodiment, the communication module may be a communication module based on UWB (Ultra-Wideband) technology. Specifically, the communication module may use UWB (Ultra-Wideband) technology to achieve high-precision time resolution and data transmission by sending short pulse signals over an ultra-wideband spectrum.

[0032] A power supply module is used to provide energy to the angle detection module and the communication module.

[0033] In this embodiment, the power module may be a rechargeable battery or a replaceable lithium battery.

[0034] In this embodiment, by integrating the angle detection module, the communication module and the power supply module into the stress gauge angle detection device, real-time rotation angle detection and remote signal transmission of the borehole stress gauge during the installation process are achieved. The angle detection module can accurately detect the rotation angle of the stress gauge in the installation hole and generate a corresponding detection signal, and the communication module transmits the detection signal to the target device, ensuring the real-time and accuracy of the data. The power supply module provides stable energy support for the entire device, enabling the device to operate reliably for a long time in a complex geological environment. Through this integrated design, this embodiment improves the installation accuracy and operating efficiency of the borehole stress gauge, reduces the complexity of manual operation, and significantly improves the reliability and safety of the overall measurement.

[0035] like Figure 3 As shown, in some embodiments, the mounting device further comprises: A communication relay device is configured to be communicatively connected to the stress gauge angle detection device and the data monitoring device respectively, and to perform communication relay on the detection signal generated by the stress gauge angle detection device before transmitting it to the data monitoring device.

[0036] The communication relay device can be a cylindrical modular relay device suitable for use in narrow passages. Alternatively, it can be an integrated pole-type relay device, integrating the signal relay function into a slender pole. This device can be easily inserted into deep holes, amplifying and transmitting signals through the relay device inside the pole.

[0037] This embodiment achieves stable transmission of stress gauge angle detection signals in deep hole environments by introducing a communication relay device. Since the depth of many installation holes may reach more than ten meters, direct wireless communication is susceptible to interference from geological structures and signal attenuation, resulting in unstable or lost data transmission. The communication relay device can establish communication connections with the stress gauge angle detection device and the data monitoring device respectively, relay the detection signal generated by the stress gauge angle detection device, and then transmit it to the data monitoring device on the ground. This not only ensures the effective transmission of signals in deep hole environments, but also significantly improves the overall reliability of the system and the accuracy of data transmission, and is suitable for high-precision monitoring needs under complex geological conditions.

[0038] In some embodiments, the connection system comprises: A connecting rod system includes at least one connecting sub-rod. When the connecting rod includes multiple connecting sub-rods, the multiple connecting sub-rods are connected in sequence through interfaces at their ends to form the connecting rod system.

[0039] In this embodiment, the interface at the end may be a threaded interface, a snap-on interface, a latch interface, or a magnetic interface.

[0040] This embodiment designs a connecting rod system so that the user can directly drive the rotation of the drilling stress gauge by rotating the connecting sub-rod, ensuring that the strain gauge accurately reaches the predetermined angle in the installation hole. The connecting rod system is composed of at least one connecting sub-rod, and several connecting sub-rods are connected in sequence through the interface at the end to form an overall connecting rod system. This modular design not only enhances the flexibility of the system, allowing users to adjust the length of the connecting rod according to different hole depths and actual needs, but also simplifies the installation operation. Without the need for additional complex tools or equipment, users only need to rotate the connecting sub-rod to accurately control the rotation angle of the strain gauge, thereby improving installation efficiency and measurement accuracy, ensuring project safety and data accuracy.

[0041] In some embodiments, the connection system further comprises: A fine-tuning motor is disposed between the strain gauge angle detection device and the connecting rod system, and is capable of rotating the drilling stress gauge to a predetermined rotation angle based on a detection signal generated by the strain gauge angle detection device.

[0042] This embodiment achieves automatic and precise rotation control of the borehole stress gauge by configuring a fine-tuning motor between the stress gauge angle detection device and the connecting rod system. The fine-tuning motor can automatically adjust the rotation angle of the strain gauge based on the detection signal generated by the stress gauge angle detection device to ensure that it accurately reaches the predetermined installation position. This design greatly reduces the reliance on manual operation accuracy, especially in deep holes or complex geological conditions, and can effectively reduce installation errors and improve measurement accuracy and reliability. Through the precise control of the fine-tuning motor, this embodiment improves the installation efficiency of the borehole stress gauge, enhances the degree of automation of the entire system, and helps to ensure the safety of the project and the accuracy of the data.

[0043] In some embodiments, the data monitoring device is a wireless data monitoring device, and the wireless data monitoring device is connected to the strain gauge angle detection device via wireless communication.

[0044] In some embodiments, the mounting device further comprises: A video data acquisition device is configured at the end of the connection system close to the stress gauge angle detection device, and is capable of acquiring video data inside the installation hole during the installation of the drilling stress gauge to generate a reliable video signal; wherein the video signal is transmitted to the data monitoring device, and the data monitoring device displays the corresponding video data.

[0045] In this embodiment, the video data acquisition device can be fixedly mounted at the front end of the connection system, near the strain gauge angle detection device, in close proximity to the strain gauge. This arrangement allows the video data acquisition device to directly capture images of the borehole bottom and in front of the strain gauge, providing the most intuitive perspective for monitoring the strain gauge installation progress and the actual conditions at the borehole bottom.

[0046] In this embodiment, the video data acquisition device can be in the form of a ring camera, mounted around the end of the connection system to ensure full coverage. The video data acquisition device can also be embedded within the rod of the connection system, with only the camera lens exposed at the end, forming an embedded design.

[0047] In this embodiment, an LED light source may be integrated around the video data acquisition device to provide necessary lighting to ensure that clear video data can still be obtained in a low-light environment.

[0048] In this embodiment, a wireless transmission module can be integrated inside the video data acquisition device to transmit the video signal to the ground data monitoring device in real time, avoiding the complexity of long-distance wired connection.

[0049] This embodiment achieves real-time video monitoring of the borehole stress gauge installation process by configuring a video data acquisition device at the end of the connection system on the side close to the stress gauge angle detection device. The video data acquisition device can collect real-time video data from inside the installation hole, generate corresponding video signals, and transmit them to the data monitoring device for display. Through video monitoring, users can intuitively observe the environmental conditions inside the borehole, promptly identify and eliminate potential installation obstacles or abnormal conditions, thereby improving the accuracy and safety of the installation. This design not only enhances the visibility of the operation, but also provides instant feedback, optimizes the installation process of the borehole stress gauge, and further ensures the reliability of the measurement data and the overall safety of the project.

[0050] like Figure 4 As shown, this embodiment provides a method for installing a drilling stress gauge, the method comprising: Step S102: inserting a drilling stress gauge into the mounting hole to a predetermined depth through a connection system; wherein one end of the drilling stress gauge is connected to one end of a stress gauge angle detection device, and the other end of the stress gauge angle detection device is connected to the connection system.

[0051] Step S104: The drilling stress gauge is rotated to a predetermined rotation angle by rotating the connection system; wherein, during the process of rotating the connection system, the drilling stress gauge is also driven to rotate, and the stress gauge angle detection device is capable of detecting the rotation angle of the drilling stress gauge and sending a detection signal representing the rotation angle to a data monitoring device capable of communicating with the data monitoring device.

[0052] Step S106: When it is determined that the drilling stress gauge has been rotated to a predetermined rotation angle based on the rotation angle displayed by the data monitoring device, the rotation is stopped.

[0053] In this embodiment, the complexity of the installation of the borehole stress gauge is significantly reduced through a series of automated and precisely controlled steps. In step S102, the borehole stress gauge is accurately inserted into the predetermined depth through the connection system to ensure the basic positioning of the installation. In step S104, the borehole stress gauge is directly driven to rotate by the rotary connection system, while the stress gauge angle detection device monitors the rotation angle in real time and transmits the detection signal to the data monitoring device. In step S106, the operator can accurately judge whether the borehole stress gauge has reached the predetermined angle through the rotation angle information displayed in real time by the data monitoring device, and stop rotating after reaching the predetermined angle. This method reduces the reliance on manual experience through real-time angle monitoring and feedback, simplifies the installation operation, ensures the precise positioning of the borehole stress gauge, and effectively solves the problem of complex and error-prone installation process in the prior art.

[0054] In some embodiments, the connected rod system includes a connecting rod system, the connecting rod system including at least one connecting sub-rod, and when the connecting rod includes multiple connecting sub-rods, the multiple connecting sub-rods are sequentially connected through interfaces at their ends to form the connected rod system; the step of rotating the borehole stress gauge to a predetermined rotation angle by rotating the connecting system includes: Manually rotating the connecting rod to rotate the drilling stress gauge; By observing the rotation angle displayed by the data monitoring device, the borehole stress gauge is rotated to a predetermined rotation angle.

[0055] In some embodiments, the connected rod system further includes a fine-tuning motor, which is disposed between the strain gauge angle detection device and the connected rod system and is capable of rotating the borehole stress gauge to a predetermined rotation angle based on a detection signal generated by the strain gauge angle detection device. The step of rotating the borehole stress gauge to the predetermined rotation angle by rotating the connection system further includes: Automatic rotation of the drilling stress gauge is achieved through the fine-tuning motor.

[0056] In a specific embodiment, the installation method may include: First, connect one end of the strain gauge angle detection device to the borehole strain gauge, and the other end to the connecting rod system and the communication relay device. It will be appreciated that the connecting rod system can include multiple interconnected connecting rods. The communication relay device can be positioned between the connecting rods.

[0057] The strain gauge angle detection device is then inserted into a pre-set deep hole via a connecting rod system. The deep hole is pre-drilled, and its angle (e.g., relative to the horizontal plane) is fixed and cannot be adjusted. A communication relay ensures that the signal generated by the strain gauge angle detection device is smoothly transmitted to the ground monitoring instrument.

[0058] Furthermore, on the one hand, workers rotate the drilling stress gauge to a preset angle by rotating the connecting rod system. On the other hand, during the rotation process, they monitor the rotation angle of the stress gauge in real time through a wireless data monitor and make necessary adjustments to ensure that the strain gauge is in the correct measurement position.

[0059] Finally, when the strain gauge is rotated to the predetermined rotation angle, the accuracy of the angle is confirmed by a wireless data monitor to ensure that the measurement is ready.
