Description

Technical Field

[0001] The present invention relates to the technical field of intelligent mine AI analysis sensors, in particular to a GUG12 intrinsically safe surrounding rock movement sensor for mining. Background Art

[0002] The mining industry usually refers to a series of economic activities involving the exploration, mining, processing, sales and related services of mineral resources. Mineral resources refer to natural resources that exist in nature, have economic value, and can be used to produce goods or provide services. The mining industry is vital to a country's economic development because it provides raw materials for industrial production and is also an important export commodity for many countries. In addition, the mining industry is closely related to employment, technological development and regional economic development. Coal mines are a common mine. The GUG12 mining intrinsically safe surrounding rock movement sensor is a device specially designed for monitoring surrounding rock displacement underground in coal mines. It can monitor the deep loosening and delamination displacement changes of coal mine roadway roof and surrounding rock in real time, and transmit data to the ground server for analysis through wireless communication technology.

[0003] After massive retrieval, it was found that the laser ranging sensors in the prior art have problems in use. Since the laser ranging sensors in the prior art measure the displacement changes of the surrounding rock and can also be wirelessly transmitted through digital display, the environment inside the coal mine tunnel is complex, and the existing sensors have a limited detection range for the displacement changes of the surrounding rock. It is difficult to perform 360° laser ranging and shooting of the specific environment in the underground tunnel, and the data collection effect is limited. Secondly, the existing GUG12 mining intrinsically safe surrounding rock mobile sensor has limited ability to analyze data, and monitoring data of different types and sources lack effective fusion and analysis, which is insufficient to process complex mine environment data. Therefore, based on the above retrieval and combined with the prior art, the GUG12 mining intrinsically safe surrounding rock mobile sensor is proposed to solve the above problems. The present invention transmits wirelessly to the substation through LORA, and the substation uploads the data to the mine intrinsically safe surrounding rock mobile system and video in the tunnel of the host computer through the gateway. The system is automatically generated and transmitted to the Huawei Industrial Internet Innovation Big Model on the well through wireless communication methods such as WIFI6 underground, so as to achieve synchronous data and video analysis and processing.

[0040] Instruction 2: The main control microcontroller of the circuit board 23 powers on the control module of the servo motor 2 14 in the housing 1, and the synchronous main control microcontroller performs self-test on the Hall element 21. In the first working cycle, the servo motor 2 14 starts to reverse the speed reduction gear body 12 to drive the rotating cam 11 to rotate, pushing the transparent cover 17 to retract into the supporting outer ring 19. The retracted position is controlled by the Hall element 21. When the Hall element 21 senses the approach of the magnetic ring 20, the transparent cover 17 is controlled by the microcontroller to retract into place, completing the self-test work, and instruction 2 is completed;

Synchronously, artificial AI analysis is performed through data comparison and video comparison. 360-degree ranging is achieved in the underground tunnels of the mine, and video monitoring and video AI video analysis are synchronized. The data is uploaded to the mine through WIFI for data docking and management. Instruction 5 is completed;

[0046] The KJ533-F(C) roof pressure monitoring system analyzes and monitors the pressure data through sensors installed on the roof. These sensors can detect small changes and convert pressure changes into electrical signals. The collected electrical signals are then sent to the monitoring substation via cables or wireless signal transmission, and preliminary data processing is performed, such as linear correction, over-limit discrimination, logical operations, etc.

[0047] The processed data is then transmitted to the ground center station through a wired or wireless network. Finally, the host of the ground center station receives the data and analyzes the data with the help of monitoring and analysis software, and displays the monitoring results in real time in the form of charts or numbers;

[0048] The video AI analysis system and laser ranging analysis system can automatically identify, analyze and understand various elements and behaviors in the video, such as people, vehicles, scenes, etc., and accurately classify and mark them.

[0049] Instruction six: Camera 6, after completing instruction five, servo motor two 14 starts to reverse, and drives rotating cam 11 to rotate through reduction gear body 12, pushing transparent cover 17 to retract into supporting outer ring 19, and the retracted position is controlled by Hall element 21; when Hall element 21 senses the approach of magnetic ring 20, it controls transparent cover 17 to retract into place through single chip microcomputer, servo motor two 14 stops rotating, and instruction six is ​​completed;

[0050] Instruction seven: After completing instruction six, the circuit board 23 instructs each unit to power off, the circuit board 23 enters the sleep mode, and enters the low power consumption mode, and instruction seven is completed;

[0051] Instruction 8: The system operates in a cycle of instructions 3, 4, 5, 6 and 7 every day. The number of sampling times per day can be determined by the program instructions in the circuit board 23 .

[0052] A specific example is: a coal mine tunnel is 1,000 meters long, and a group of mine-use intrinsically safe surrounding rock displacement sensors are installed every 50 meters, with a total of 20 devices.

The half gear 2 48 swings back and forth to make the half gear 1 47 drive the support box 44 and the cleaning brush 46 to swing back and forth. The cleaning brush 46 swings back and forth and rotates around the transparent cover 17 to brush off the coal dust on the transparent cover 17.

[0067] At the same time, the swinging of the support box 44 also causes part of the hot air to blow onto the cleaning brush 46, causing the soot in the bristles of the cleaning brush 46 to fall off, thereby improving the cleaning effect. The soot on the outer wall of the transparent cover 17 is cleaned, which helps the camera 6 to shoot and the laser head 7 to measure the distance, thereby improving the data accuracy.

[0068] On the other hand, the cleaning of the coal ash on the outer wall of the transparent cover 17 also prevents the coal ash from being stuck in the gap between the transparent cover 17 and the supporting outer ring 19 during the expansion and contraction of the transparent cover 17, thereby preventing the transparent cover 17 from tilting due to the coal ash being stuck in the gap between the transparent cover 17 and the supporting outer ring 19, so that the camera 6 and the laser head 7 are tilted, so that the accuracy of the data collected by the camera 6 and the laser head 7 is improved, which is convenient for the subsequent analysis of the situation in the coal mine tunnel according to the data;

[0069] In addition, before the transparent cover 17 is extended or retracted, the device program automatically controls the start of the second micro motor 42, and the drive shaft of the second micro motor 42 rotates to drive the mounting plate 43 to rotate outward, and the mounting plate 43 rotates outward to drive the cleaning brush 46 to move outward, so as to prevent the cleaning brush 46 from affecting the extension and retraction of the transparent cover 17;

[0070] The driving member includes a driving gear 39, which is meshed and connected to the outer circumferential wall of the gear ring 38. A micro motor 40 for driving the driving gear 39 to rotate is installed on one side of the housing 1. One end of the driving shaft of the micro motor 40 is fixedly connected to one end of the driving gear 39. The micro motor 40 drives the driving gear 39 to rotate. The driving gear 39 rotates to drive the gear ring 38 and the two half gears 48 to rotate around the transparent cover 17:

[0071] Among them, by controlling the micro motor 1 40, the gear ring 38 and the transparent cover 17 rotate at the same speed, so that the two cleaning brushes 46 continuously clean the outer wall of the transparent cover 17;

[0072] Specifically, the micro motor 40 is provided, and the driving shaft of the micro motor 40 rotates to drive the driving gear 39 to rotate, and the driving gear 39 rotates to drive the gear ring 38 to rotate, and the gear ring 38 rotates to make the cleaning brush 46 move along the outer wall of the transparent cover 17, thereby driving the cleaning brush 46 to move;

[0073] An annular groove 36 for supporting the rotation of the gear ring 38 is provided on one side of the housing 1. A support ring 37 is fixedly installed on one side of the gear ring 38. The support ring 37 is rotatably connected to the annular groove 36. The cross sections of the annular groove 36 and the support ring 37 are both T-shaped, which improves the rotation stability of the gear ring 38 and prevents the gear ring 38 from falling from the side of the housing 1.

[0074] Specifically, the gear ring 38 is provided, and the rotation of the gear ring 38 drives the support ring 37 to rotate inside the annular groove 36. The cooperation between the annular groove 36 and the support ring 37 can limit the rotation of the gear ring 38, thereby improving the stability of the rotation of the gear ring 38.

[0075] A fixing plate 53 is fixedly installed on one side of the gear ring 38, and a second fan 54 is rotatably connected inside the fixing plate 53. The initial angle of the laser head 7 is vertically upward, and the initial angle of the second fan 54 is also vertically upward. When the transparent cover 17 drives the laser head 7 to rotate for distance measurement, the second fan 54 synchronously makes a circular motion and generates an airflow to blow away the coal dust in the distance measurement direction of the laser head 7, further preventing the laser head 7 from being affected by the coal dust in the coal mine tunnel;

[0076] Specifically, by the laser head 7, when the laser head 7 rotates to measure the distance of the coal mine tunnel, the fixed plate 53 and the second fan 54 will also rotate with it. At the same time, the second fan 54 rotates to generate airflow, and the airflow blows away the coal dust in the distance measurement direction of the laser head 7 to prevent the laser generated by the laser head 7 from being blocked by the coal dust, further avoiding the laser head 7 from being affected by the coal dust in the coal mine tunnel, and further improving the distance measurement accuracy;

[0077] A baffle 59 is fixedly installed on the inner circular wall surface of the transparent cover 17, and a plurality of mounting blocks 60 are fixedly installed on one side of the baffle 59. A movable block 61 is rotatably connected between every two mounting blocks 60. An electric push rod 57 is fixedly installed on one side of the movable block 61. The telescopic shaft of the electric push rod 57 is universally connected to one side of the support plate 1 56 through a universal joint. A gyroscope 55 is fixedly installed on one side of the support plate 1 56. The gyroscope 55 can detect whether the support plate 1 56 is horizontal. If the support plate 1 56 is tilted, the telescopic shafts of the plurality of electric push rods 57 can be moved outward or contracted to keep the support plate 1 56 horizontal, so that the camera 6 and the laser head 7 are always horizontal. An information processing module for processing information is fixedly installed on one side of the support plate 1 56.

[0078] Specifically, through the transparent cover 17, although the cleaning brush 46 cleans the soot on the outer wall of the transparent cover 17 during the extension and retraction of the transparent cover 17, part of the soot may still be stuck in the gap between the transparent cover 17 and the supporting outer ring 19 during the extension and retraction of the transparent cover 17. At this time, the transparent cover 17 is tilted by the soot, and the tilt of the transparent cover 17 causes the supporting plate 156 inside the transparent cover 17 to tilt. When the gyroscope 55 on the supporting plate 156 detects its tilt, it transmits information to the information processing module. After processing the information, the information processing module feeds back to the multiple electric push rods 57. The telescopic axes of the multiple electric push rods 57 move outward or contract to adjust the angle of the supporting plate 156 to keep it horizontal, so as to make the camera 6 and the laser head 7 level, thereby preventing the accuracy of the camera 6 shooting and the laser head 7 ranging from being reduced due to the tilt.

[0079] Working principle: by turning on the self-locking switch 25, the circuit board 23 is powered on and its unit is self-checked, and then the battery 22 powers the servo motor 14, and the Hall element 21 self-checks, which is conducive to the servo motor 14 driving the rotating cam 11 to shrink the transparent cover 17. Correspondingly, the servo motor 14 rotates forward to make the transparent cover 17 extend into place, and the telescopic movement of the transparent cover 17 is detected. The photoelectric switch 8 and the servo motor 10 are powered on, and the servo motor 10 is reset to the zero position. The servo motor 10 drives the camera 6 and the laser head 7 to rotate to collect data and upload it for analysis. After the data collection is completed, the servo motor 14 drives the transparent cover 17 to shrink into place, and the motors of each unit are dormant to reduce power consumption;

[0080] The heating wire 58 is provided to heat the airflow generated by the second half gear 48. The bottom surface of the support box 44 is provided with an air outlet. The hot air dries the coal ash on the outer wall of the transparent cover 17, which is convenient for subsequent cleaning.

[0081] Secondly, the driving shaft of the driving motor 51 rotates to drive the connecting rod 50 and the sliding column 52 to rotate. The sliding column 52 rotates so that the positioning plate 49 drives the half gear 2 48 to rotate back and forth. The half gear 2 48 rotates back and forth through the half gear 1 47 to make the support box 44 and the two cleaning brushes 46 swing back and forth. The two cleaning brushes 46 swing back and forth to clean the soot on the transparent cover 17. Then the gear ring 38 drives the two cleaning brushes 46 to rotate around the transparent cover 17, thereby fully cleaning the soot on the transparent cover 17.

[0082] At the same time, when the transparent cover 17 drives the laser head 7 to rotate for distance measurement, the fan 2 54 synchronously makes a circular motion and generates an airflow to blow away the coal dust in the distance measurement direction of the laser head 7, further preventing the laser head 7 from being affected by the coal dust in the coal mine tunnel;

[0083] Finally, the gyroscope 55 can detect whether the support plate 56 is horizontal. If the support plate 56 is tilted, the telescopic axes of the multiple electric push rods 57 can be moved outward or retracted to keep the support plate 56 horizontal, so that the camera 6 and the laser head 7 are always horizontal.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
