Description

Technical Field

[0001] The present application relates to the technical field of mine safety monitoring, and in particular to a device for analyzing the stability of a mine pillar based on image recognition-ultrasonic combined monitoring. Background Art

[0002] In the mining industry, pillars are key structures that maintain the stability of underground mining spaces. Their stability is directly related to the safety and production efficiency of mining operations. Traditional pillar stability monitoring relies on single detection methods, such as manual inspections or simple instrument measurements. These methods suffer from low efficiency, large errors, and the inability to monitor in real time. As mining depth and scale continue to expand, the stress environment of pillars becomes increasingly complex, and even minor structural damage can lead to serious safety accidents. Furthermore, the harsh environment of mines, such as humidity, dust, and high vibration, can easily cause dust accumulation and damage to the sensors of monitoring equipment, resulting in inaccurate detection data.

[0003] The inventors discovered the following deficiencies in the aforementioned related technologies: Most existing devices rely on manual cleaning of dust from the pillar surfaces, which is inefficient and incomplete. This can easily lead to poor contact between the detection probe (such as an image sensor or ultrasonic probe) and the pillar surface, significantly affecting detection accuracy due to human factors. The lack of an adaptive cleaning mechanism makes it difficult to conform to curved pillar surfaces (such as circular and irregular shapes), resulting in significant dust residue on edges and indentations, affecting the reliability of detection data. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-7 This application is described in further detail.

[0031] The embodiments of the present application disclose a device for analyzing the stability of a mine pillar based on image recognition and ultrasonic combined monitoring.

[0032] See also Figure 1 The device for analyzing pillar stability, based on combined image recognition and ultrasonic wave monitoring, includes a housing 1, a pillar cleaning mechanism 2 mounted on one side, a detection mechanism 4 located within the housing, and a sensor cleaning mechanism 3 located on top. Housing 1 provides a mounting platform for each mechanism. Pillar cleaning mechanism 2 pre-clears dust from the pillar surface to prevent debris from interfering with detection. Detection mechanism 4 integrates core detection components to accurately detect pillar status. Sensor cleaning mechanism 3 regularly maintains detection probes to ensure long-term stable operation. These three mechanisms work together to enhance monitoring reliability.

[0033] See also Figures 2 to 7 The pillar cleaning mechanism 2 includes a cleaning assembly for cleaning the pillars and a pulley drive assembly for driving the cleaning assembly. The cleaning assembly comprises a base plate 201 for movably mounting a spiral cleaning rod 203, a first rubber sheet 202 for contacting the pillar surface, the spiral cleaning rod 203 for removing dust from the pillar surface, and a second rubber sheet 204 for movably mounting the spiral cleaning rod 203 in conjunction with the base plate 201. The first rubber sheet 202, due to its flexibility, tightly adheres to the irregular surface of the pillars, while the second rubber sheet 204 assists in stabilizing the rotational trajectory of the spiral cleaning rod 203. The combination of the two enables the spiral cleaning rod 203 to efficiently remove dust and debris attached to the pillar surface, providing a clean test surface for subsequent testing and ensuring that test data is not affected by surface impurities.

[0034] The sensor cleaning mechanism 3 includes a cleaning assembly for cleaning the sensor probe built into the detection mechanism 4, and a spring reset assembly that drives the cleaning assembly's displacement and reset. The cleaning assembly comprises a slide 304 movably mounted within a chute 301 and a scraper 307 for scraping dust off the sensor probe's surface. The chute 301 provides linear guidance for the slide 304. The scraper 307 follows the slide 304's movement, conforming to the sensor probe's surface and effectively removing dust particles accumulated during the detection process. The spring reset assembly automatically returns the slide 304 to its original position after the cleaning operation, maintaining the sensor probe in a clean, detectable state and reducing the need for manual maintenance.

[0035] Detection mechanism 4 includes a sensor assembly for detecting the status of the pillars and a handle assembly for the operator to grip the device. The handle assembly includes a positioning block 403 fixedly mounted inside the device housing 1 and a sealing plate 404 to prevent dust from entering the housing 1. The sensor assembly integrates multiple detection technologies to comprehensively capture information such as stress and cracks in the pillars. The handle assembly is securely connected to the device housing 1 via positioning block 403, and the sealing plate 404 forms a dust-proof barrier with the housing, ensuring a comfortable grip for the operator while effectively preventing dust from entering the device, protecting the delicate electronic components.

[0036] The pulley drive assembly of the pillar cleaning mechanism 2 includes a top plate 205 that prevents the belt body 208 from derailing, a pulley 207 for driving the belt body 208, a small motor 206 that provides power to the pulley 207, and a traction pulley 209 for increasing the tension of the top plate 205. The top plate 205 is connected to one side of the spiral cleaning rod 203 via a belt drive. The small motor 206 is fixedly mounted on the top of the equipment housing 1. The output end of the small motor 206 is fixedly connected to the pulley 207. The traction pulley 209 is movably mounted on the top of the second rubber plate 204. The small motor 206 drives the belt body 208 through the pulley 207. The traction pulley 209 adjusts the belt tension in real time. The top plate 205 limits the belt's motion trajectory, ensuring that the spiral cleaning rod 203 maintains a stable speed. Even in the humid and dusty environment of the mine, the surface cleaning of the pillars can be completed continuously and efficiently, providing stable prerequisites for the inspection process.

[0037] The spring return assembly of the sensor cleaning mechanism 3 includes limit rods 302 movably mounted on the left and right sides of the slide 304, a spring body 303 sleeved on one side of the limit rods 302, a pull rod 305 fixedly connected to the top of the slide 304, and a first handle 306 for lifting the slide 304. The limit rods 302 are fixedly mounted within the slide slots 301, which are located on the left and right sides of the device housing 1. When the operator pulls the pull rod 305 using the first handle 306, the slide 304 slides. The spring body 303 compresses or expands on the limit rods 302, which restrict the range of movement of the slide 304. This allows the scraper 307 to contact the sensor probe with constant pressure, thoroughly removing dust while preventing damage to the probe due to excessive force, thus achieving dual controllable cleaning force and stroke.

[0038] The sensor assembly of detection mechanism 4 includes a sensor module 402 for image recognition and ultrasonic detection, and a wireless signal output module 405 for transmitting wireless signals. The image sensor and ultrasonic sensor probes of sensor module 402 extend through the device housing 1, and the surfaces of the image sensor and ultrasonic sensor probes coincide with the movement trajectory of scraper bar 307. Sensor module 402 combines image recognition and ultrasonic detection technologies to comprehensively assess the structural stability of the pillar from both visual and acoustic perspectives. Wireless signal output module 405 transmits detection data to the backend system in real time, enabling remote monitoring personnel to obtain timely information on the pillar's status, providing real-time, comprehensive decision-making for mine safety management.

[0039] Bottom plate 201 is bolted to the bottom of device housing 1. The top of bottom plate 201 is fixedly connected to first rubber plate 202. The left and right sides of first rubber plate 202 are flexibly connected to spiral cleaning rods 203, which are flexibly sleeved onto the bottom of second rubber plate 204. The bolted connection ensures a secure connection between bottom plate 201 and device housing 1. The first rubber plate 202, thanks to its flexibility, conforms closely to the curved surface of the pillar, ensuring that spiral cleaning rod 203 remains close to the pillar surface during rotation. Second rubber plate 204 provides auxiliary support for the cleaning rod, reducing its shaking during operation and ensuring the stability and efficiency of the cleaning process.

[0040] Scraper bar 307 is fixedly connected to one side of slide plate 304 and movably mounted within retaining groove 308. Retaining groove 308 is located on the side of device housing 1 away from sealing plate 404 and is used to securely mount sensor module 402. Retaining groove 308 provides a precise moving track for scraper bar 307, ensuring that it maintains parallel contact with the surface of the sensor probe during sliding. This not only thoroughly scrapes away dust particles on the probe, but also avoids blind spots caused by offset cleaning. Combined with the reciprocating motion of slide plate 304, it achieves comprehensive cleaning of the sensor probe.

[0041] The ultrasonic detection end of sensor module 402 is equipped with a dust filter made of corrosion-resistant metal. Its surface forms a sliding seal with the contact surface of scraper bar 307. The dust filter prevents larger particles from entering the ultrasonic detection end. Its corrosion-resistant material adapts to the complex, damp and dusty environment of a mine. The sliding seal allows scraper bar 307 to fit tightly against the filter surface during cleaning, removing dust from the filter while maintaining the seal at the detection end and ensuring the proper transmission and reception of ultrasonic signals.

[0042] The bottom of the device housing 1 is equipped with an arc-shaped groove that matches the shape of the pillar. The inner wall of the arc-shaped groove is covered with a non-slip rubber layer, forming a continuous contact surface between the non-slip rubber layer and the first rubber plate 202. The arc-shaped groove is designed to fit the cylindrical shape of the pillar. The non-slip rubber layer increases the friction between the device and the pillar surface, preventing the device from slipping during inspection. The continuous contact surface tightly connects the dust cleaning mechanism to the pillar surface, forming a locally enclosed space, reducing the spread of dust during cleaning, improving the working environment, and enhancing cleaning efficiency.

[0043] Spring body 303 adopts a double-helix symmetrical structure, with its ends fixedly connected to the end of limit rod 302 and the inner wall of slideway 301, respectively. The travel of slide plate 304 is determined by the length of limit rod 302 and the compression limit of spring body 303. This double-helix symmetrical structure enables spring body 303 to provide a uniform and stable restoring force, ensuring balanced force on slide plate 304 during reciprocating motion. The limit rod 302 and the spring's compression limit jointly limit the travel of slide plate 304, preventing spring failure due to excessive stretching or compression, ensuring long-term and reliable operation of sensor cleaning mechanism 3 and reducing the risk of mechanical failure.

[0044] Positioning block 403 is fixedly mounted within positioning slot 401, which is located on one side of device housing 1 and has the same dimensions as sealing plate 404. Positioning block 403 precisely matches positioning slot 401, firmly securing the handle assembly to device housing 1 and ensuring the device does not wobble when held by an operator. Sealing plate 404, which is the same size as positioning slot 401, tightly fills the gap between the handle and the housing, effectively preventing mining dust from entering the device through the installation gap and creating a clean working environment for detection mechanism 4.

[0045] Example

[0046] Initial stability test of newly mined pillars

[0047] In newly mined areas of a mine, after the initial formation of a pillar, an initial stability test is required to ensure the safety of subsequent mining operations. Operators approach the pillar with a pillar stability analysis device that uses image recognition and ultrasonic wave technology to monitor the pillar's stability.

[0048] First, align the arc-shaped groove at the bottom of the device housing 1 that matches the shape of the mine pillar with the mine pillar. Since the inner wall of the arc-shaped groove is covered with an anti-slip rubber layer, and a continuous fitting surface is formed between the anti-slip rubber layer and the first rubber plate 202, the device can be stably fitted on the surface of the mine pillar. Next, start the mine pillar cleaning mechanism 2 to clean the surface of the mine pillar to prevent dust from affecting subsequent detection. The pulley transmission assembly of the mine pillar cleaning mechanism 2 starts working, and the small motor 206 fixedly mounted on the top of the device housing 1 provides power for the entire transmission. Its output end is fixedly connected to the pulley 207, driving the pulley 207 to rotate. The pulley 207 is driven by the belt body 208. The top plate 205 is mounted on one side of the belt body 208 to prevent the belt body 208 from derailing. The traction wheel 209 movably mounted on the top of the second rubber plate 204 is used to increase the tension of the top plate 205 to ensure the stability of the transmission. Driven by the pulley transmission assembly, the spiral cleaning rod 203 begins to rotate. The spiral cleaning rod 203 is movably mounted between the bottom plate 201 and the second rubber plate 204. The bottom plate 201 is fixed to the bottom of the equipment housing 1 by bolts, and the top is fixedly connected to the first rubber plate 202. The left and right sides of the first rubber plate 202 are movably connected to the spiral cleaning rod 203. The second rubber plate 204 cooperates with the bottom plate 201 to movably mount the spiral cleaning rod 203, and the spiral cleaning rod 203 is movably sleeved on the bottom of the second rubber plate 204. The rotating spiral cleaning rod 203 can effectively remove dust from the surface of the mine pillar, preparing for subsequent inspections.

[0049] After completing the cleaning of the pillar surface, the operator needs to clean the sensor probes built into the detection mechanism 4 to ensure the accuracy of the detection data. At this point, the sensor cleaning mechanism 3 begins operation. The operator grasps the first handle 306 and pulls the slide 304 using the pull rod 305. The slide 304 is movably mounted within the chute 301 on the left and right sides of the device housing 1. Limit rods 302 are mounted on each side of the slide 304. A spring body 303 is sleeved onto one side of the limit rod 302, with its ends fixedly connected to the ends of the limit rod 302 and the inner wall of the chute 301, respectively. When the slide 304 is pulled, it moves within the chute 301, and a scraper 307 mounted on one side of the slide 304 also moves accordingly. The scraper 307 is movably mounted within a limit slot 308 on the side of the device housing 1 away from the sealing plate 404. The image sensor and ultrasonic sensor probes of the sensor module 402 extend through the device housing 1, and their surfaces overlap with the movement trajectory of the scraper 307. Therefore, the scraper 307 can scrape dust off the sensor probe surfaces. After cleaning is completed, the first handle 306 is released, and under the restoring action of the spring body 303, the slide plate 304 and the scraper 307 return to their initial positions.

[0050] Finally, the operator grasps the handle assembly inside the device housing 1. The handle assembly includes a positioning block 403 fixedly mounted inside the device housing 1 and a sealing plate 404 to prevent dust from entering the device housing 1. The positioning block 403 is fixedly mounted inside a positioning slot 401 on the side of the device housing 1. The positioning slot 401 is the same size as the sealing plate 404, allowing the operator to hold the device steadily. The sensor assembly of the detection mechanism 4 begins operation. The sensor module 402 detects the status of the pillar through image recognition and ultrasonic waves. Its ultrasonic detection end is equipped with a dust filter made of corrosion-resistant metal. The surface of the dust filter forms a sliding seal with the contact surface of the scraper 307, which prevents dust from entering without affecting the cleaning operation of the scraper 307. The detected data is transmitted to an external device via a wireless signal output module 405, allowing the operator to analyze the stability of the pillar.

[0051] The implementation principle of the device for analyzing pillar stability based on image recognition and ultrasonic combined monitoring is as follows:

[0052] First, the operator aligns the arc-shaped groove at the bottom of the equipment housing 1 with the mine pillar, and uses the continuous fitting surface formed by the anti-slip rubber layer and the first rubber plate 202 to make the equipment stably fit the surface of the mine pillar. Then, the mine pillar cleaning mechanism 2 is started, and the small motor 206 fixed on the top of the equipment housing 1 drives the pulley 207 to rotate. The pulley 207 drives the spiral cleaning rod 203 to rotate through the belt body 208. The top plate 205 prevents the belt body 208 from derailing, and the traction wheel 209 increases the tension of the top plate 205 to ensure stable transmission. The spiral cleaning rod 203, with the cooperation of the bottom plate 201 and the second rubber plate 204, fits tightly to the surface of the mine pillar, removes dust and debris, and provides a clean surface for subsequent inspection.

[0053] Secondly, after the surface of the mine pillar is cleaned, the operator holds the first handle 306 and lifts the slide 304 through the pull rod 305. The slide 304 moves in the slide groove 301 opened on the left and right sides of the equipment housing 1. Since the limit rods 302 are installed on the left and right sides, and the spring body 303 is sleeved on one side of the limit rod 302, and the two ends are fixedly connected to the end of the limit rod 302 and the inner wall of the slide groove 301 respectively, the movement stroke of the slide 304 is limited, and the scraper 307 installed on one side of the slide 304 moves accordingly to scrape off the dust on the surface of the image sensor and ultrasonic sensor probe of the sensor module 402 that penetrates the equipment housing 1. After cleaning, release the first handle 306, and the spring body 303 resets the slide 304 and the scraper 307.

[0054] Next, the operator holds the handle assembly inside the device housing 1. The positioning block 403 in the handle assembly is fixedly installed in the positioning groove 401. The sealing plate 404 prevents dust from entering the interior of the device. The positioning groove 401 is the same size as the sealing plate 404, which makes it easy for the operator to hold the device stably and keep the device in good detection contact with the mine pillar.

[0055] Next, the sensor assembly of the detection mechanism 4 starts working. The sensor module 402 uses the image recognition function to visually observe whether there are cracks, peeling and other phenomena on the surface of the pillar; using the ultrasonic detection function, it deeply detects changes in the internal structure of the pillar, such as internal cracks, stress concentration and other problems. The corrosion-resistant metal dust filter at the ultrasonic detection end forms a sliding sealing structure with the contact surface of the scraper 307, which is dust-proof and does not affect cleaning.

[0056] Finally, the data detected by the sensor module 402 is transmitted to an external device through the wireless signal output module 405, such as a terminal carried by patrol personnel or a mine monitoring center. Relevant personnel analyze the transmitted data to determine the stability of the pillars and provide a decision-making basis for mine safety production.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
