[0002] Currently, with the surge in coal demand, the scale of underground coal mining has also expanded accordingly. During the production and mining process in underground coal mines, tunneling and extraction operations alter the underground geological conditions.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0023] The following reference Figures 1 to 8 This application describes a coal mine safety monitoring and inspection device and inspection method according to some embodiments.

[0024] like Figure 1As shown, the first aspect of this application proposes a coal mine safety monitoring and inspection device, comprising: a support plate base 1; a central base 3, disposed on the support plate base 1, with a rotating shaft base 4 at the bottom of the central base 3; multiple sets of lifting rod mechanisms 2, spaced apart on the support plate base 1 and arranged around the central base 3; a monitoring probe 7, disposed on the side of the central base 3 away from the lifting rod mechanism 2; a wind fin mechanism 5, rotatably connected to the rotating shaft base 4, configured to rotate under wind force and maintain alignment with the wind direction; a wireless transmission sensor probe 6, disposed on the wind fin mechanism 5 and rotating with the wind fin mechanism 5, such that the detection head of the wireless transmission sensor probe 6 is in the windward direction; a wind-powered rotation mechanism, disposed on the rotating shaft base 4, with its input end connected to the wind fin mechanism 5; and a cleaning brush 8, connected to the output end of the wind-powered rotation mechanism, with the brush head of the cleaning brush 8 in contact with the monitoring probe 7.

[0025] The coal mine safety monitoring and inspection device provided in this application includes a support plate base 1, a central base 3, multiple sets of boom mechanisms 2, a monitoring probe 7, a wind fin mechanism 5, a wireless transmission sensor probe 6, a wind-driven rotation mechanism, and a cleaning brush 8. The monitoring probe 7 is located on the side of the central base 3 away from the boom mechanism 2, providing a wide field of view and clear monitoring of the coal mine environment, thus providing basic data for safety. The wireless transmission sensor probe 6 is mounted on the wind fin mechanism 5, which rotates with the wind, ensuring the detection head always faces the wind. This enables real-time, directional, and accurate sampling and monitoring of flowing gases in the mine, effectively overcoming the monitoring blind spots or data lag problems caused by changes in wind direction of fixed sensors, and improving the timeliness and reliability of monitoring hazardous gases such as methane and carbon monoxide.

[0026] The device uses the airflow commonly found in mines as a power source. The wind-powered rotation mechanism uses the power generated by the rotation of the wind fin mechanism 5 by the wind to transmit the kinetic energy through the transmission connection, driving the cleaning brush 8 to work and continuously or intermittently clean the lens of the monitoring probe 7 automatically. No additional energy supply is required, which reduces the operating cost of the device and is green and environmentally friendly, meeting the needs of sustainable development in coal mines.

[0027] The cleaning brush 8 is connected to the output end of the wind-powered self-rotating mechanism. The brush head contacts the monitoring probe 7. Driven by wind, it can continuously and automatically clean the dust and stains on the surface of the monitoring probe 7, ensuring a clear monitoring image and avoiding inaccurate monitoring data due to dirt obstruction, thus ensuring the long-term stable operation of the device.

[0028] The coal mine safety monitoring and inspection device provided in this application is based on the support plate base 1, with the central base 3 and the hanging rod mechanism 2 arranged in a reasonable manner. The wind fin mechanism 5 is rotatably connected to the rotating shaft base 4. All components work together, and the structure is compact and stable. It can adapt to the complex and harsh environment of coal mines, improve the reliability and service life of the device, and provide strong protection for safe production in coal mines.

[0029] like Figure 5As shown, in some embodiments provided in this application, the suspension mechanism 2 includes: a fixed seat 21, disposed on the support plate seat 1; a universal shaft 24, disposed at the upper end of the fixed seat 21; a ceiling seat 28; and a screw telescopic assembly, connected between the universal shaft 24 and the ceiling seat 28, for adjusting the distance between the ceiling seat 28 and the support plate seat 1.

[0030] In this embodiment, the boom mechanism 2 includes a fixed base 21, a universal joint 24, a ceiling mount 28, and a screw telescopic assembly. The fixed base 21 is mounted on the support plate 1, providing a stable support foundation for the entire mechanism. The universal joint 24 is connected to the upper end of the fixed base 21, allowing for flexible rotation at multiple angles. It can quickly adjust the direction of the boom mechanism 2 according to the complex and diverse spatial layout and equipment installation requirements of the coal mine site, easily adapting to installation needs at different positions and angles, thus improving the ease of installation and applicability of the device.

[0031] The screw telescopic assembly connects the universal joint 24 to the ceiling mount 28. By rotating the screw, the distance between the ceiling mount 28 and the support plate 1 can be precisely and smoothly adjusted. This adjustment method is simple to operate, can achieve stepless distance adjustment, and can meet the installation requirements of equipment at different heights and the height requirements of different monitoring scenarios, ensuring that the coal mine safety monitoring and inspection device is in the optimal working position.

[0032] All components are tightly connected. The universal joint 24 and the screw telescopic assembly have high strength and good wear resistance, and can withstand external forces such as vibration and impact that may occur in the coal mine environment, ensuring the long-term stable operation of the boom mechanism 2 and providing reliable support for the equipment above.

[0033] like Figure 5 As shown, in some embodiments provided in this application, the screw telescopic assembly includes: a telescopic sleeve 26; a first telescopic screw 25, connected to a universal joint 24 and screwed onto one end of the telescopic sleeve 26; and a second telescopic screw 27, connected to a ceiling seat 28 and screwed onto the other end of the telescopic sleeve 26; wherein the threads of the first telescopic screw 25 and the second telescopic screw 27 are opposite in direction.

[0034] In this embodiment, the screw telescopic assembly includes a telescopic sleeve 26, a first telescopic screw 25, and a second telescopic screw 27. Since the threads of the first telescopic screw 25 and the second telescopic screw 27 have opposite directions, when the telescopic sleeve 26 is rotated, the first telescopic screw 25 and the second telescopic screw 27 will move simultaneously in opposite directions. This allows for a single rotational action to quickly increase or decrease the distance between the ceiling mount 28 and the support plate 1, simplifying the height adjustment process and saving time and manpower. It is particularly suitable for scenarios in coal mine environments where frequent equipment height adjustments are required.

[0035] The threaded connection itself has self-locking properties. After being adjusted to the appropriate height, the telescopic sleeve 26 can be tightly engaged with the first telescopic screw 25 and the second telescopic screw 27, effectively preventing accidental slippage caused by external forces or equipment vibration, ensuring that the ceiling seat 28 is stably maintained at the required height, providing reliable support for the equipment above, and ensuring the accurate operation of the coal mine safety monitoring and inspection device.

[0036] like Figure 5 As shown in some embodiments provided in this application, the coal mine safety monitoring and inspection device further includes: a plurality of positioning screws 22, which are spaced apart on the fixed base 21, and each positioning screw 22 is slidably connected to a heightening pad 23.

[0037] In this embodiment, by adding an appropriate number of heightening pads 23 to the outside of the positioning screw 22, the height of the lifting mechanism 2 can be flexibly adjusted. When the lifting mechanism 2 is set to 3 sets, by precisely adjusting the number of heightening pads 23 on each positioning screw 22, the three sets of lifting mechanisms 2 can rotate and fold at different heights using the universal joint 24 as the axis. In this way, the three sets of lifting mechanisms 2 can be stably hung and fixed to the mine wall in the form of three-point horizontal support, thus perfectly adapting to the actual environment of the mine and ensuring that the entire coal mine safety monitoring and inspection device can operate stably and efficiently.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments provided in this application, the monitoring probe 7 is a 360-degree panoramic camera probe.

[0039] In this embodiment, the 360-degree panoramic camera probe can achieve full-view coverage in both horizontal and vertical directions, capturing every corner of the coal mine environment in real time and eliminating the monitoring blind spots present in traditional probes. Whether it's a corner of a roadway, behind equipment, or other hidden areas, everything can be clearly displayed, ensuring that no safety hazard can hide.

[0040] Panoramic imagery can acquire information about a large area of ​​a scene at once, reducing the stitching errors and information omissions that may occur when using multiple single cameras in combination, thus improving the completeness and accuracy of information acquisition. At the same time, it allows monitoring personnel to quickly and comprehensively understand the situation on-site, make timely decisions, and improve emergency response speed.

[0041] like Figure 6 and Figure 7As shown, in some embodiments provided in this application, the wind fin mechanism 5 includes: a wind guide sleeve 51, including a slot, on which a slot 53 is provided, the wind guide sleeve 51 being rotatably connected to the rotating shaft seat 4 through the slot 53; a wind guide groove 54, which is opened on the outer side wall of the wind guide sleeve 51; a wind deflector plate 55, which is disposed on one side of the wind deflector groove 54; and a wind tail fin 56, which is disposed on the other side of the wind deflector groove 54; wherein, the detection head of the wireless transmission sensor probe 6 faces the windward side where the wind deflector plate 55 is located.

[0042] In this embodiment, the wind fin mechanism 5 includes a guide sleeve 51, a guide trough 54, a wind deflector plate 55, and a wind tail fin 56. The guide sleeve 51 is rotatably connected to the rotating shaft seat 4 via a slot 53, ensuring the stability of the connection and allowing the guide sleeve 51 to rotate flexibly. The guide trough 54 is formed on the outer wall of the guide sleeve 51, which can effectively guide the airflow. The wind deflector plate 55 adopts a V-shaped structure, and the sharp corner of the wind deflector plate 55 is precisely aligned with the wind direction, which can efficiently capture and guide the wind force. The wind deflector plate 55 and the wind tail fin 56 are respectively set on both sides of the guide trough 54. The two cooperate with each other, enabling the wind fin mechanism 5 to quickly respond to changes in wind direction under the action of wind force, stably align with the wind direction, and always maintain consistency with the wind direction, providing a stable foundation for subsequent testing.

[0043] The detection head of the wireless transmission sensor probe 6 faces the windward side where the diversion plate is located. This allows the detection port to directly and continuously face the airflow, reducing interference from the tunnel walls and dust contamination of the sampled airflow. Combined with the converging effect of the airflow guide duct 54, the speed and efficiency of the airflow passing through the sensor's sensitive element are improved, thus making the gas monitoring results more real-time and accurate.

[0044] The air guide sleeve 51, air guide duct 54, wind force diversion plate 55 and wind force tail fin 56 together constitute a reasonable wind force diversion structure, which can reasonably disperse and guide the wind force, reduce the impact of the wind force on the whole device, enhance the stability and wind resistance of the entire wind fin mechanism 5 and even the entire monitoring and inspection device in harsh wind environments, and ensure the long-term reliable operation of the device.

[0045] In some embodiments provided in this application, the wireless transmission sensing probe 6 includes one or more of a gas sensor, an oxygen concentration sensor, a carbon monoxide sensor, and a dust concentration sensor.

[0046] In this embodiment, multiple sensors work together to simultaneously monitor key indicators in the coal mine environment, such as methane, oxygen, carbon monoxide, and dust concentrations. Comprehensive data acquisition allows for the timely detection of potential safety hazards, such as methane accumulation, insufficient oxygen, carbon monoxide leaks, and excessive dust levels, providing comprehensive and accurate data support for safe coal mine production.

[0047] One or more sensors can be flexibly selected and installed according to the actual conditions and monitoring priorities of different coal mines to meet diverse monitoring needs, avoid resource waste, and improve monitoring efficiency and relevance.

[0048] Wireless transmission enables sensor data to be transmitted to the monitoring terminal in real time and quickly, eliminating the need for cumbersome wiring, reducing installation and maintenance costs, while ensuring that monitoring personnel can obtain information in a timely manner, make quick decisions, effectively prevent accidents, and protect the lives of underground workers.

[0049] like Figure 3 As shown, in some embodiments provided in this application, the coal mine safety monitoring and inspection device further includes: a support rod 11, which is disposed on the central seat 3, and a monitoring probe 7 is disposed at the bottom end of the support rod 11.

[0050] In this embodiment, the coal mine safety monitoring and inspection device also includes a support rod 11. The support rod 11 is mounted on the central seat 3, with the monitoring probe 7 positioned at its bottom, effectively expanding the monitoring range of the probe 7. The support rod 11 employs a telescopic structure; by reasonably adjusting its length and angle, the monitoring probe 7 can cover the coal mine operating area from a more suitable angle, reducing blind spots and ensuring comprehensive, real-time monitoring of personnel activities and equipment operation underground.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments provided in this application, the wind-powered self-rotation mechanism includes: a rotating shaft 9, sleeved on a supporting rod 11; a transmission gear 52, disposed on the inner wall of the wind fin mechanism 5; a transmission gear 13, disposed at the top of the rotating shaft 9; at least three star gears 12, spaced apart on the rotating shaft seat 4, and meshing between the transmission gear 52 and the transmission gear 13; wherein, a cleaning brush 8 is disposed on a rotating bushing 10 at the bottom of the rotating shaft 9.

[0052] In this embodiment, the wind-powered self-rotation mechanism includes a rotating shaft 9, a transmission gear 52, a transmission gear 13, and at least three star gears 12. When the wind fin mechanism 5 rotates under wind power, the transmission gear 52 on its inner wall rotates accordingly. Through at least three star gears 12 that are spaced apart and meshed between the transmission gear 52 and the transmission gear 13, the power is smoothly and efficiently transmitted to the transmission gear 13 located at the top of the rotating shaft 9, thereby driving the rotating shaft 9 to rotate, realizing the effective conversion and transmission of wind power into mechanical power.

[0053] The rotating shaft 9 is sleeved on the supporting rod 11, which is structurally stable. The cleaning brush 8 installed on the rotating bushing 10 at the bottom of the rotating shaft 9 can rotate stably with the rotating shaft 9 to continuously clean the surface of the monitoring probe 7, effectively removing dust, stains, etc., ensuring clear monitoring images and guaranteeing the accuracy of monitoring data.

[0054] The components of this device work together seamlessly and have a rational transmission system, enabling it to withstand certain vibrations and interferences and operate stably in the complex and harsh environment of coal mines. Furthermore, it requires no additional energy, utilizing only wind power to achieve its self-rotating cleaning function, thus reducing operating costs, improving energy efficiency, and providing reliable support for safe coal mine production.

[0055] like Figure 8 As shown, the second aspect of this application provides a coal mine safety monitoring and inspection method, employing the coal mine safety monitoring and inspection device as described in any of the above embodiments, including the following steps: S202: By adjusting the boom mechanism, the coal mine safety monitoring and inspection device is installed at a predetermined position in the mine. S204: Activate the monitoring probe to perform panoramic visual monitoring of the mine environment and acquire visual data; S206: The wind fin mechanism is driven to rotate adaptively to align with the wind direction by the mine airflow, and gas parameters are monitored and gas sensing data is acquired by wirelessly transmitting sensor probes. S208: Transmits visual data and gas sensor data to the monitoring terminal; S210: The wind-driven self-rotation mechanism, driven by the rotation of the wind fin mechanism, drives the cleaning brush to rotate, automatically cleaning the lens of the monitoring probe.

[0056] The coal mine safety monitoring and inspection method provided in this application allows for flexible and precise installation of the device at a predetermined location within the mine through the adjustment of the boom mechanism, adapting to the complex and ever-changing mine environment. After activating the monitoring probe, it enables 360-degree panoramic visual monitoring of the mine environment, acquiring visual data from all directions, eliminating blind spots, and providing a clear overview of the underground situation, thus offering rich evidence for safety assessments.

[0057] By utilizing the inherent natural airflow within the mine as the driving energy source, two parallel and collaborative work chains are simultaneously triggered: First, the wind fin mechanism is driven to adaptively align with the wind direction, ensuring that the wireless transmission sensor probe can perform directional and accurate real-time sampling, effectively capturing the migration and diffusion patterns of hazardous gases and improving the timeliness of early warnings; Second, the same rotational mechanical energy is transferred through the wind-powered rotation mechanism and converted into a cleaning brush that accompanies the automatic cleaning of the monitoring lens, solving the industry pain point of lens blurring and visual monitoring failure caused by dust accumulation underground, and ensuring the continuous clarity and reliability of panoramic visual data.

[0058] The mine ventilation-driven fin mechanism adaptively rotates and aligns with the wind direction, ensuring that the wireless transmission sensor probe can accurately capture gas information in the airflow, monitor gas parameters such as methane and oxygen in real time, and obtain accurate and reliable gas sensing data, which helps to detect gas anomalies in a timely manner and prevent accidents such as explosions and poisoning.

[0059] Visual and gas sensor data can be transmitted to the monitoring terminal in a timely manner, facilitating remote monitoring and rapid decision-making by staff. Simultaneously, the rotation of the wind fin mechanism drives the wind-powered self-rotating mechanism, which in turn drives the cleaning brush to automatically rotate and clean the monitoring probe lens, ensuring the lens remains clear and maintaining high-quality visual monitoring. This eliminates the need for frequent manual cleaning, reducing maintenance costs and workload, and enhancing the overall intelligence and reliability of monitoring and inspection, thus providing strong support for safe coal mine production.

By adding an appropriate number of heightening pads 23 to the outer side of the positioning screws 22, the support height of the hanging rod mechanism 2 can be flexibly adjusted, so that the three sets of hanging rod mechanisms 2 can rotate and fold at different heights with the universal joint 24 as the axis, and be horizontally fixed to the mine wall in a three-point horizontal support manner to match the mine environment.

[0069] A universal joint 24 is provided on the upper end of the support of the fixed base 21. A ceiling seat 28 is provided directly above the bearing of the universal joint 24. The universal joint 24 and the ceiling seat 28 are connected by a screw telescopic assembly. The screw telescopic assembly includes a telescopic sleeve 26. One end of the threaded tube of the telescopic sleeve 26 is screwed with a first telescopic screw 25 that is fixedly connected to the universal joint 24. The other end of the threaded tube of the telescopic sleeve 26 is screwed with a second telescopic screw 27 that is fixedly connected to the ceiling seat 28. The threads of the first telescopic screw 25 and the second telescopic screw 27 are arranged symmetrically in opposite directions. By using the thread extension and retraction of the first telescopic screw 25, the second telescopic screw 27 and the telescopic sleeve 26, the two sets of telescopic screws can be extended and retracted by pushing the telescopic sleeve 26 to rotate, thereby adjusting the length of the lifting rod of the lifting rod mechanism 2 to adapt to the uneven installation environment in the mine.

[0070] A support rod 11 is installed through the central axis of the support of the central seat 3, and a monitoring probe 7 is suspended at the bottom of the arm of the support rod 11. A wireless transmission sensor probe 6 is installed on the upper part of the wind plate of the wind fin mechanism 5 along its wind channel direction. The monitoring probe 7 is a 360-degree panoramic camera probe. There are multiple sets of wireless transmission sensor probes 6, including but not limited to gas sensors, oxygen concentration sensors, carbon monoxide sensors, and dust concentration sensors. Based on the panoramic monitoring of the monitoring probe 7 in the form of a 360-degree panoramic camera probe, the circumferential environment inside the mine is inspected and monitored. Through the sensing and monitoring of the wireless transmission sensor probe 6, the gases such as gas, oxygen, carbon monoxide, and dust in the mine air are dynamically monitored.

[0071] A pivot seat 4 is provided at the bottom of the support of the center seat 3. A wind fin mechanism 5 is rotatably connected to the outer side of the pivot seat 4. The wind fin mechanism 5 includes a guide sleeve 51. The slot of the guide sleeve 51 is provided with a slot 53 that is rotatably connected to the pivot seat 4. A guide channel 54 is provided on the outside of the guide sleeve 51. A wind deflector plate 55 is provided on one side of the channel of the guide channel 54. A wind tail fin 56 is provided on the other side of the channel of the guide channel 54. The guide channel 54 corresponds to the detection head of the wireless transmission sensor probe 6. The mine needs to be equipped with ventilation equipment to maintain air flow in the mine. When the air is circulating in the mine, the wind force is complex and variable in the complex environment of the mine. Therefore, by using the combination of the wind deflector plate 55, the guide channel 54 and the wind tail fin 56, the wind fin mechanism 5 can turn synchronously with the wind force and keep in the same direction as the wind force, thereby improving the timeliness and efficiency of the monitoring and sensing of the wireless transmission sensor probe 6.

[0072] The bottom of the shaft seat 4 is equipped with a wind-powered self-rotation mechanism opposite to the wind fin mechanism 5, and the bottom of the shaft of the wind-powered self-rotation mechanism is equipped with a cleaning brush 8 opposite to the monitoring probe 7. The wind-powered self-rotation mechanism includes a rotating shaft 9 rotatably connected to the middle of the support of the shaft seat 4 and sleeved on the outside of the arm of the support rod 11, and a transmission gear plate 52 installed on the inner wall of the wind fin mechanism 5. The top of the sleeve of the rotating shaft 9 is equipped with a transmission gear 13, and the transmission gear 13 and the transmission gear plate 52 are connected by a star-triangle mounting. The star gear 12 on the rotating shaft seat 4 meshes and drives the rotating shaft 9. The bottom end of the arm of the rotating shaft 9 is provided with a rotating bushing 10 that is fixedly connected to the cleaning brush 8. While the wind fin mechanism 5 rotates and swings, it drives the transmission gear disk 52 on its inner wall to rotate synchronously. Then, by using the differential meshing transmission between the star gear 12 and the transmission gear 13, the rotating shaft 9 is driven to rotate, which in turn drives the cleaning brush 8 to rotate around the monitoring probe 7, so as to perform self-cleaning on the lens of the monitoring probe 7 and ensure the clear monitoring performance of the monitoring probe 7.

[0073] This application also provides a coal mine safety monitoring and inspection method for coal mine safety management, including the following steps: S1. Fixed-point installation: a. Ceiling installation: Based on the coal mine site environment, the three sets of hoisting rods arranged in a star-triangle pattern are suspended from the top of the mine shaft. During the hoisting process, the length of the hoisting rods is adjusted based on the telescopic adjustment performance of the screw telescopic components in the hoisting rods to adapt to the complex and varied installation conditions inside the mine. b. Side-mounted installation: Based on the coal mine site environment, the three sets of hoisting mechanisms arranged in a star-triangle pattern are horizontally mounted on the mine pit wall. While being horizontally mounted, the hoisting mechanism maintains different turning heights by combining the positioning screws and heightening pads. Then, with the universal linkage of the universal joint and the extension and retraction adjustment of the screw extension assembly, it is installed and positioned horizontally to adapt to the complex and ever-changing installation conditions inside the mine. S2. Monitoring and Inspection: a. Based on 360-degree panoramic monitoring of surveillance probes, dynamic safety monitoring is carried out on the working conditions of workers and the operation of equipment in the mine. b. Based on the wind fin mechanism, the wind tail fin swings, so that the wind fin mechanism can turn dynamically in real time with the wind direction in the mine and keep in line with the wind direction. At the same time, the sensing and monitoring of the wireless transmission sensor probe is used to conduct dynamic real-time monitoring of the gas environment in the mine. S3, Terminal Monitoring, is based on wireless communication technology to transmit monitoring content to the terminal monitoring device in real time for real-time dynamic monitoring. S4. The monitoring probe self-cleaning mechanism is based on the wind-driven rotation of the wind fin mechanism. The power generated by its rotation is transmitted to the cleaning brush through the differential transmission of the wind-driven rotation mechanism, which drives the cleaning brush to rotate and dynamically self-clean the monitoring probe lens, reducing the adhesion of coal mine dust.

[0074] How this application works: Fixed-point installation is divided into two types: ceiling installation and side-mounted installation. For ceiling installation, based on the coal mine site environment, three sets of suspension rod mechanisms arranged in a star-triangle pattern are suspended from the top of the mine shaft. During the suspension, the length of the suspension rods is adjusted based on the telescopic adjustment performance of the screw telescopic components in the suspension rod mechanism to adapt to the complex and ever-changing installation conditions inside the mine. Side-mounted installation: Based on the coal mine site environment, the three sets of hoisting mechanisms arranged in a star-triangle pattern are horizontally mounted on the mine pit wall. While being horizontally mounted, the hoisting mechanism maintains different turning heights by combining the positioning screws and heightening pads. Then, with the universal linkage of the universal joint and the extension and retraction adjustment of the screw telescopic components, it is installed and positioned in a horizontal manner to adapt to the complex and ever-changing installation conditions inside the mine. Monitoring and Inspection: Based on the 360-degree panoramic monitoring of the monitoring probe, dynamic safety monitoring is carried out on the working conditions of workers and the operation of equipment in the mine; based on the wind fin mechanism, the wind fin mechanism is dynamically turned in real time with the wind direction in the mine, keeping in line with the wind direction; at the same time, the sensing and monitoring of the wireless transmission sensor probe is used to carry out dynamic real-time monitoring of the gas environment in the mine. Terminal monitoring: Based on wireless communication technology, the monitoring content is transmitted to the terminal monitoring device in real time for real-time dynamic monitoring. Surveillance camera self-cleaning: Based on the wind-powered rotation of the fin mechanism, the power generated by its rotation is transmitted to the cleaning brush through the differential transmission of the wind-powered rotation mechanism, which drives the cleaning brush to rotate and dynamically self-clean the monitoring probe lens, reducing the adhesion of coal mine dust.

[0075] Compared with related technologies, the beneficial effects of this application are as follows: 1. Significantly improved installation adaptability, solving installation challenges in complex mine environments. Existing inspection devices mostly adopt a single fixed installation method, which is difficult to adapt to the complex environment of mines with uneven ceilings and varied pit wall structures, easily leading to unstable installation or monitoring blind spots. This application provides a dual-mode "ceiling installation + side-mounted installation" through three sets of hoisting mechanisms arranged in a star-delta configuration: when ceiling-mounted, the hoisting rod length can be flexibly adjusted through the screw telescopic component; when side-mounted, the installation height can be adjusted through the combination of positioning screws and heightening pads. Combined with the universal joint's universal linkage performance, this achieves stable installation of the device in different mine environments, completely solving the problems of "difficult installation and poor adaptability" of existing devices.

[0076] 2. Dual optimization of monitoring accuracy and coverage to reduce the risk of interference and omissions. Existing devices are often affected by variable wind direction and dust accumulation in mines, resulting in problems such as delayed gas monitoring, blurry video monitoring, and limited coverage. This application achieves two major design breakthroughs: First, the wind fin mechanism can dynamically rotate in real time with the wind direction in the mine, ensuring that the wireless transmission sensor probe is always facing the airflow direction, significantly improving the timeliness and accuracy of hazardous gas monitoring; second, it adopts a 360-degree panoramic monitoring probe, combined with the collaborative monitoring of multiple sets of sensors, to achieve comprehensive coverage of "personnel operation behavior + equipment operating status + gas environment," effectively avoiding the monitoring deviations, missed reports, and false alarms caused by interference in existing devices.

[0077] 3. Self-cleaning function reduces operation and maintenance costs and ensures continuous and effective monitoring. Existing devices require regular manual cleaning of coal mine dust from the surface of the monitoring probes, which not only increases operation and maintenance costs but may also lead to monitoring interruptions due to untimely cleaning. This application utilizes the wind-driven rotation of the wind fin mechanism, through differential transmission, to drive the cleaning brush to automatically rotate and clean the monitoring probe lens. No additional power or manpower is required, which avoids dust obstruction and interference with video monitoring, reduces operation and maintenance workload and costs, and ensures continuous and stable monitoring.

[0078] 4. Integrated and coordinated design enhances monitoring efficiency and improves the safety early warning mechanism. Existing devices often have independent monitoring, transmission, and maintenance modules, making it difficult to form an efficient and collaborative monitoring system. This application achieves integrated coordination of "installation-monitoring-transmission-cleaning": the wind fin mechanism provides both "wind-following" monitoring optimization for the gas sensor and power for the cleaning brush; wireless communication technology transmits video and gas data to the terminal in real time, forming a closed-loop system of "real-time monitoring-dynamic early warning-autonomous maintenance." Compared to the "distributed operation" of existing devices, this significantly improves overall monitoring efficiency, enabling timely detection of safety hazards such as personnel violations and gas leaks, and improving the coal mine safety early warning and prevention mechanism.

[0079] In summary, this application relates to the field of coal mine safety monitoring technology. It is not a simple assembly of existing technologies, but rather addresses the core pain points of existing coal mine safety monitoring and inspection devices—namely, "weak anti-interference, low accuracy, narrow coverage, and difficult operation and maintenance"—through in-depth adaptation to the complex environment of mines and systematic optimization of monitoring logic. The device has a reasonable structural design, convenient monitoring methods, and the ability to flexibly adapt to different mine environments. It also possesses accurate and comprehensive multi-dimensional monitoring performance and can reduce operation and maintenance costs through self-cleaning, forming an integrated safety monitoring system.

[0080] From a practical application perspective, this device effectively fills the gaps in existing technologies for dynamic monitoring and early warning in coal mines, providing "real-time, accurate, and comprehensive" safety assurance for underground coal mining operations and helping coal mine safety management upgrade from "passive prevention and control" to "proactive early warning." Its technical solution is mature and feasible, requiring no reliance on complex external equipment, and is easily scalable and widely adopted. It is of great significance for improving the level of safe coal mining in my country and reducing safety accidents, possessing excellent industrialization prospects and social value.
