Description

Technical Field

[0001] This utility model relates to the field of mining operation technology, and more specifically, to a portable mining inclined hole measurement and monitoring device. Background Technology

[0002] With the continuous development of modern mining technology and the increasing demands for safe production, mine geological structure monitoring has become a crucial technical means to ensure safe mine production and prevent geological disasters. During mining operations, the continuous blasting and excavation activities cause complex changes in the underground rock structure, easily leading to geological deformation phenomena such as fissures, displacement, and settlement. If these changes are not monitored and warned of in a timely and accurate manner, they may result in major safety accidents such as collapses, landslides, and water inrushes. Therefore, establishing a comprehensive mine geological monitoring system to monitor the stability of underground rock strata in real time is of significant practical importance for ensuring the safety of mine workers, improving mining efficiency, and extending the service life of mines.

[0003] Currently, mine geological monitoring primarily relies on borehole inclination measurement technology to monitor the deformation of underground rock strata. This technology involves drilling monitoring holes at predetermined locations and then using inclination instruments to periodically measure changes in the inclination angle at different depths within the holes, thereby analyzing and determining the displacement and deformation trends of the strata. Existing mine inclination borehole measurement equipment typically employs a fixed installation method, permanently burying sensors within the monitoring holes and transmitting data to a ground monitoring center via wired or wireless means to achieve long-term continuous monitoring of changes in underground structures. This type of equipment plays a crucial role in long-term stability monitoring and provides vital data support for mine safety management.

[0004] However, existing fixed-position inclined borehole surveying equipment in mines has significant limitations in practical applications. First, the equipment is complex and costly to install, requiring specialized technicians for intricate installation work. Once installed, it is difficult to move and reconfigure, failing to meet the flexible adjustment needs of monitoring points during mining operations. Second, fixed equipment is bulky, inconvenient to carry and transport, and difficult to deploy quickly and for emergency monitoring in the complex and ever-changing mining environment. Third, traditional equipment often relies on complex power supply and communication systems, which are prone to failure in harsh mining environments, resulting in high maintenance costs and insufficient reliability. Finally, existing equipment lacks portability and flexibility, failing to meet the urgent need for temporary and mobile monitoring of different areas during mining operations, thus limiting the efficiency and coverage of monitoring work.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

A clamping bolt is installed through one end of the connecting arm, with one end tangent to the outer side of the open collar. When the clamping bolt is screwed in, the open collar radially contracts to clamp the angle adjustment assembly.

[0010] Furthermore, in order to facilitate insertion into the oblique hole, the angle adjustment assembly includes an adjustment shaft that passes through one side of the height adjustment assembly. One end of the adjustment shaft is provided with a connector, one end of the connector is provided with a locking nut, and the other end of the connector is fixedly connected to the measuring outer tube.

[0012] Furthermore, in order to achieve reliable acquisition and transmission of sensor measurement data, the inner measuring arm includes a measuring rod disposed inside the outer measuring tube. An observation slot is provided at the bottom of one side of the measuring rod, and a transparent glass plate is disposed inside the observation slot. Fixed terminals are provided through the top and bottom of the observation slot on one side of the measuring rod.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a portable mine inclined hole measurement and monitoring device is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the portable mine inclined hole measurement and monitoring device according to an embodiment of the present invention includes: Support rod 1 is used to support the entire measurement and monitoring equipment; Mounting slot 2 is located on one side of support rod 1 and is designed as a long strip structure; The height adjustment component 3 is sleeved on the outside of the support rod 1 and is used to cooperate with the mounting groove 2 to achieve height adjustment; The fixing ring 4 is located on the top outer side of the support rod 1; Display 5, located on one side of the fixing ring 4, is used to display the measurement results in real time; An angle adjustment component 6 is disposed through one side of the height adjustment component 3 and is used to adjust the measurement angle; The measuring outer tube 7 is installed through the top side of the angle adjustment component 6 to house and protect the measuring component; The inner measuring arm 8 is set inside the outer measuring tube 7 and is used to extend into the inclined hole for displacement measurement; The sensing probe 9 is set at one end of the measuring inner arm 8 and is used to acquire the inclination angle data inside the inclined hole.

[0022] In one embodiment, a handle 10 is fitted at the bottom of the support rod 1 for easy gripping and carrying of the equipment by the operator; a cylindrical controller is provided at the top inner side of the measuring outer tube 7 for supplying power to the sensing probe 9 and receiving sensing data signals, and transmitting the processed data to the display 5 wirelessly; a triaxial tilt sensor is provided inside the sensing probe 9 for measuring the tilt angle changes at different depths and positions within the inclined hole.

[0023] In one embodiment, for the height adjustment component 3 and the angle adjustment component 6, the height adjustment component 3 includes an adjustment seat 301 sleeved on the outside of the support rod 1. The adjustment seat 301 has a circular through-hole structure inside and a square structure outside. Locking bolts 302 that mate with the mounting groove 2 are provided through the top and bottom of one side of the adjustment seat 301. Both the locking bolts 302 and the inner wall of the mounting groove 2 are threaded, used to fix the adjustment seat 301 by rotating the locking bolts 302 to engage with the threaded structure of the mounting groove 2. A connecting arm 303 is provided on the other side of the adjustment seat 301. A connecting arm 303 is provided on one side of the adjustment seat 301. The connecting arm 303 has a first protrusion extending laterally. A second protrusion, cooperating with the first protrusion, is provided on one side of the connecting arm 303 near the adjusting seat 301. Several fixing bolts 304 pass through the first and second protrusions. An open collar 305, cooperating with the angle adjusting assembly 6, passes through the other side of the connecting arm 303. A clamping bolt 306 passes through one end of the connecting arm 303, and one end of the clamping bolt 306 is tangent to the outer side of the open collar 305. This allows the open collar 305 to radially contract when the clamping bolt 306 is screwed in, thereby clamping the angle adjusting assembly 6. The angle adjusting assembly 6 includes an adjusting shaft 601 passing through one side of the height adjusting assembly 3. A connector 602 is provided at one end of the adjusting shaft 601, and a locking nut 603 is provided at one end of the connector 602. The other end of the connector 602 is fixedly connected to the measuring outer tube 7, thereby achieving angle adjustment between the measuring outer tube 7 and the height adjusting assembly 3, and stable locking of the angle adjusting assembly 6 within the open collar 305.

[0024] The working principle of the height adjustment component 3 and the angle adjustment component 6 is as follows: At the mine inclined hole measurement site, when it is necessary to adjust the equipment height, the operator first loosens the locking bolt 302. At this time, the fixing force between the adjusting seat 301 and the mounting groove 2 is weakened, allowing the adjusting seat 301 to slide freely up and down along the mounting groove 2 of the support rod 1. After reaching the desired height position, the operator rotates the locking bolt 302 clockwise, so that it fits tightly with the threaded structure on the inner wall of the mounting groove 2, generating radial pressure to firmly fix the adjusting seat 301 at the specific height position of the support rod 1. In addition, when it is necessary to adjust the measurement angle, the operator can loosen the clamping bolt 306. At this time, the radial clamping force of the open collar 305 is reduced, allowing the adjusting shaft 601 to rotate freely within the open collar 305. After adjusting to the desired angle, the operator screws in the clamping bolt 306 again to increase the radial clamping force of the open collar 305, thereby firmly locking the angle adjustment component 6 at the specific angle position. Through the synergistic effect of this multi-level adjustment mechanism, the height adjustment component 3 can work with the angle adjustment component 6 to achieve precise adjustment and positioning of the measuring device in both vertical height and horizontal angle dimensions, meeting the needs of different inclined hole measurement scenarios.

[0025] It should be noted that when performing inclined hole measurements in a mining environment, the operator needs to hold the handle 10 at the bottom of the support rod with one hand while continuously monitoring the data readings on the display 5. Since the device is handheld, a fixed height would require operators of different heights to awkwardly bend over or raise their arms to hold it, leading to excessive fatigue in the arms, shoulders, and lower back muscles during prolonged use, affecting measurement accuracy and work efficiency. The height adjustment component 3 allows users to flexibly adjust the device height according to their individual height and arm length while maintaining a comfortable grip: the operator simply loosens the locking bolt 302, holds the handle 10 with one hand, and easily adjusts the adjustment seat 301 by sliding it up and down along the support rod 1 with the other hand; after finding the most ergonomic height, the locking bolt 302 is tightened to securely lock the adjustment seat 301 in the optimal position on the support rod 1. This design not only allows the operator to maintain a natural standing posture and a relaxed grip, reducing the burden on the arms and shoulders and avoiding muscle fatigue and hand tremors caused by prolonged gripping, but also effectively adjusts the height of the display 5, keeping the line of sight at the most comfortable angle. This user-friendly height-adjustable design fully considers the operational characteristics of handheld devices, enabling the equipment to maintain portability while providing a customized user experience for operators of different heights, significantly improving the comfort and continuous working capacity of on-site measurements in mines.

[0026] In one embodiment, for the aforementioned measuring outer tube 7 and measuring inner arm 8, the measuring outer tube 7 includes a guide sleeve 701 that passes through the angle adjustment assembly 6. A guide groove 702 is provided on one side of the guide sleeve 701, and a conical guide cover 705 is provided at the bottom of the guide sleeve 701. A first arc-shaped snap-fit ​​structure 703 is provided at the top and middle of the guide groove 702, and a second arc-shaped snap-fit ​​structure 704 is provided at the bottom of the guide groove 702. The second arc-shaped snap-fit ​​structure 704 and the first arc-shaped snap-fit ​​structure 703 are arranged in a barb-like manner to cooperate with each other, which is used to position and fix the measuring inner arm 8 at different positions. The inner measuring arm 8 includes a measuring rod 801 disposed inside the outer measuring tube 7. An observation groove 802 is provided at the bottom of one side of the measuring rod 801, and a transparent glass plate is disposed inside the observation groove 802. Fixed terminals 803 are provided through the top and bottom of the observation groove 802 on one side of the measuring rod 801. A snap-fit ​​post 804 is provided at the top of one side of the measuring rod 801. A spindle-shaped grip part 805 is provided at one end of the snap-fit ​​post 804. A spiral cable 806 is provided between the two sets of fixed terminals 803. The sensing probe 9 is connected to the cylindrical controller inside the outer measuring tube 7 through the spiral cable 806, thereby realizing the adjustability of the measurement depth and the reliable transmission of sensing measurement data.

[0027] The working principle of the measuring outer tube 7 and the measuring inner arm 8 is as follows: The conical guide cover 705 is designed with a conical structure to facilitate alignment of the equipment with the inclined hole inlet, aiding in positioning for insertion into the inclined hole. When measurement is required, the operator holds the spindle-shaped grip 805, inserts the measuring inner arm 8 into the measuring outer tube 7 along the guide groove 702, and, according to the required depth of the inclined hole, engages the locking post 804 into the corresponding position of the first arc-shaped locking structure 703 or the second arc-shaped locking structure 704. The observation slot 802 and transparent glass plate on the measuring rod 801 allow the operator to visually observe the internal cable connection status of the measuring inner arm 8, facilitating timely fault detection and maintenance. The sensing probe 9 is connected to the cylindrical controller inside the measuring outer tube 7 via a spiral cable 806. The spiral design ensures that the cable is not excessively stretched or tangled during the extension and retraction of the measuring inner arm 8, effectively protecting the stable transmission of sensing data.

[0028] Furthermore, the snap-fit ​​post 804 at the top, together with the measuring outer tube 7, abuts against the bottom of the cylindrical controller, forming a rigid connection structure and facilitating the winding of the spiral cable 806. Similarly, the snap-fit ​​post 804 at the bottom allows the spiral cable 806 to be routed around and connected to the sensing probe 9, ensuring reliable signal transmission between the sensing probe 9 and the cylindrical controller. It is worth noting that the power supply of the entire monitoring device adopts an integrated design: the power required by the sensing probe 9 is directly supplied by the cylindrical controller through the spiral cable 806. The cylindrical controller has a built-in 3.7V / 2000mAh lithium battery, supporting more than 8 hours of continuous operation. The power for the display 5 comes from a detachable cylindrical power supply compartment integrated at the top of the fixing ring 4. This power supply compartment is fixedly connected to the support rod 1 and contains an 18650 lithium battery pack. It is connected to the display 5 through low-impedance wires pre-embedded inside the fixing ring 4, ensuring stable power supply during data display and supporting hot-swappable battery replacement to meet the needs of long-term field operations. As the core processing unit of the entire system, the cylindrical controller is not only responsible for the acquisition and preliminary processing of sensor data, but also can transmit the processed high-precision measurement data to the display 5 in real time via Bluetooth 4.2 protocol, enabling operators to obtain stable and reliable inclined hole inclination parameters in complex mining environments.

[0029] In practical applications, the cylindrical controller can use a TI MSP430 series low-power microcontroller or an STM32F103 series microcontroller, and is equipped with a Nordic nRF24L01+ wireless transmission module. The display 5 uses a 3.5-inch TFT color touch screen. The sensing probe 9 includes a spherical hard protective shell, a three-axis tilt sensor, and a signal processing circuit board. Among them, the three-axis tilt sensor uses the Rion-JT3 series three-axis tilt sensor with MEMS technology and an IP67 protection rating to ensure reliable working performance in complex mining environments. The hard protective shell is used to prevent the probe from being mechanically damaged during measurement. The signal processing circuit board is used to filter, amplify, and digitize the raw sensor data to improve the anti-interference ability and data accuracy of the measurement signal.

[0030] It should be noted that the three-section length adjustment design of the measuring outer tube 7 and the measuring inner arm 8 is based on the actual needs of inclined hole measurement in mines. The depth of inclined holes in the mining environment varies, ranging from tens of centimeters to hundreds of centimeters. If the operator simply relies on the extension and retraction of their arm to adapt to different depths, it will not only cause excessive arm fatigue during the measurement process, but also lead to unstable measurement data due to uneven arm strength. This design, through the multi-stage locking structure (the first arc-shaped locking structure 703 at the top and middle and the second arc-shaped locking structure 704 at the bottom) set on the guide groove 702, allows the measuring inner arm 8 to be initially locked at three different length positions according to the depth of the inclined hole. The operator only needs to make small adjustments to their arm based on this, which greatly reduces the muscle burden of long-term measurement operations. When measuring shallow oblique holes, the locking post 804 can be locked at the top first arc-shaped locking structure 703 to maintain the shortest measurement length; when measuring medium-depth oblique holes, it is locked at the middle first arc-shaped locking structure 703; and for deeper oblique holes, it can be locked at the bottom second arc-shaped locking structure 704 to fully extend the measurement length. This graded adjustment mechanism allows the operator to maintain a relatively fixed standing position and natural grip posture when holding the device, without frequent bending or arm extension, effectively avoiding muscle tremors and data inaccuracies caused by overextension of the arm, while significantly reducing the operator's physical exertion. This ergonomic advantage is particularly evident in work scenarios that require continuous measurement of multiple oblique holes. In addition, the hook-shaped locking structure ensures that the inner measuring arm 8 will not retract due to accidental collisions after locking, further improving the safety and measurement stability during handheld operation.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical applications, mining technicians need to measure the inclination angle of multiple inclined holes in blasting areas, where the portability of this equipment is particularly advantageous. Operators can easily carry the entire set of equipment to the measurement site by holding the handle 10 at the bottom of the support rod 1 with one hand. Depending on individual height and usage habits, operators loosen the locking bolt 302, adjust the position of the height adjustment component 3 on the mounting groove 2, and tighten the locking bolt 302 to fix the adjustment seat 301 after finding a comfortable operating height. For inclined holes of different angles, operators loosen the clamping bolt 306 to adjust the angle adjustment component 6, ensuring that the conical guide cover 705 of the measuring outer tube 7 is precisely aligned with the inlet of the inclined hole, and then tighten the clamping bolt 306 to lock the opening collar 305. Depending on the depth of the inclined hole, operators hold the spindle-shaped grip 805 and engage the locking post 804 of the measuring inner arm 8 into the first arc-shaped locking structure 703 or the second arc-shaped locking structure 704 on the guide groove 702. Subsequently, sensor probe 9 begins collecting data, which is transmitted to the cylindrical controller via spiral cable 806 and wirelessly to display 5 for real-time display of the measurement results. The entire measurement process is convenient and efficient. After operation, the device can be quickly stored and moved to the next measurement point, fully demonstrating the portability and flexible adjustment design advantages of this device.
