[0027] In one embodiment, the second mounting part 3 includes a second mounting plate 31 disposed on the top of the turntable 24 and a second stud 32 disposed inside the second mounting plate 31 and threadedly connected to the second mounting plate 31. The second mounting plate 31 is locked and fixed at the bottom center position of the turntable 24 by the second stud 32, forming an integrated linkage structure with the first adjusting member 2. It can rotate 360° horizontally synchronously with the turntable 24. The detachable structure facilitates the disassembly, maintenance and replacement of parts in the later stage of the equipment. At the same time, the second mounting plate 31 is made of thickened steel plate, which has strong load-bearing capacity and can stably support the second adjusting member 4 and all equipment structures below the safety monitoring part 44.

[0028] In a specific embodiment, the second adjusting member 4 includes a support frame 41 disposed at the bottom of the second mounting plate 31, and a rotating column 42 rotatably disposed within the support frame 41, with a second angle sensor disposed on the rotating column 42; It also includes a rotating block set on the outer wall of the rotating column 42, and a second driving component 43 set on the outer wall of the support frame 41 for driving the rotating column 42. The second adjusting component 4 is a device pitch angle adjustment mechanism, fixed to the bottom of the second mounting plate 31. The support frame 41 is a U-shaped rigid frame structure with reserved rotation positions at both ends. The rotating column 42 is horizontally rotated and assembled inside the support frame 41 to achieve 0-180° pitch rotation. The second driving component 43 adopts a waterproof and explosion-proof stepper motor, fixed on the outside of the support frame 41, and its output end is rigidly connected to the end of the rotating column 42 to provide power for the rotation of the rotating column 42. A square rotating block is fixed on the outer wall of the rotating column 42 as the mounting carrier of the safety monitoring unit 44. The rotation of the rotating column 42 can drive the rotating block and the safety monitoring unit 44 to adjust pitch synchronously. With the horizontal rotation of the first adjusting component 2, the monitoring equipment can achieve all-round, blind-spot-free multi-angle monitoring.

It is suitable for working conditions with large amounts of coal dust and heavy water vapor in the mine. The drive unit 75 uses a miniature waterproof motor. The cleaning brush 74 is covered with a high-density flexible cleaning brush 74. The end face of the cleaning brush 74 is slightly in contact with the lens surface of the monitoring camera 444. When coal dust and water mist adhere to the lens surface, causing the image to become blurry and the monitoring to fail, the drive unit 75 can drive the drive gear 76 to rotate. The drive gear 76 drives the driven gear ring 73 and the slip ring 72 to rotate in the annular slide rail 71. The cleaning brush 74 automatically wipes and cleans the protective cover 6 without the need for manual disassembly and maintenance, thus continuously ensuring the clarity of the monitoring image and the monitoring accuracy.

[0031] In one embodiment, the limiting member 5 includes a rotating body 52 disposed at the end of the rotating column 42, and an anti-slip sleeve 53 disposed on the outer wall of the rotating body 52; It also includes a telescopic rod 51 located at the bottom of the second mounting plate 31, directly opposite the anti-slip sleeve 53, and an anti-slip body 54 located at the telescopic end of the telescopic rod 51. A limiting member 5 is used for angle locking and positioning of the second adjusting member 4. The telescopic rod 51 is an electric telescopic push rod, fixed to the bottom of the second mounting plate 31, with the anti-slip body 54 mounted downwards at the telescopic end. The rotating body 52 is fixed to the end of the rotating column 42, and its outer wall is covered with an anti-slip sleeve 53 made of anti-slip rubber. When the second adjusting member 4 is adjusted to the specified pitch angle, the telescopic rod 51 extends, causing the anti-slip body 54 to press tightly against the anti-slip sleeve 53. This frictional force achieves locking and positioning of the rotating column 42, preventing angle deviation and monitoring wobbling caused by equipment vibration.

[0032] In a specific embodiment, the first mounting part 1 includes a first mounting plate 11 disposed on the top of the first driving component 21, and first studs 12 disposed at the four corners of the first mounting plate 11 for connecting to the coal mine roadway. The first mounting plate 11 is made of high-strength stainless steel and has rust-proof, vibration-proof, and corrosion-proof properties, making it suitable for the humid underground environment. The four corners of the first mounting plate 11 have through holes, and the first studs 12 pass through the through holes and are threadedly fastened to the drilled holes in the rock wall at the top of the roadway, so as to realize the overall suspension and fixation of the equipment, avoiding the impact of water accumulation and dust at the bottom of the roadway on the equipment. An installation position is reserved at the bottom center of the first mounting plate 11 for fixing and assembling the first adjusting component 2, ensuring the stability of the equipment's center of gravity and avoiding displacement and shaking during long-term use.

[0033] In use, first determine the equipment installation location based on the tunnel construction location, drill holes at the corresponding positions on the top rock wall of the tunnel, attach the first mounting plate 11 to the rock wall, and lock it in place with the first stud 12. Then, fix the second mounting plate 31 to the bottom of the turntable 24 of the first adjusting component 2 with the second stud 32. Then, assemble the second adjusting component 4, safety monitoring unit 44, cleaning unit 7, and limiting component 5 in sequence to complete the overall equipment installation. Connect the equipment to the underground monitoring power supply system and data transmission system, complete the power-on debugging, and the staff issues adjustment commands through the ground monitoring terminal to start the first driving component 21. The first drive component 21 drives the rotating shaft 22 and the turntable 24 to rotate. The first angle sensor 23 collects rotation angle data in real time and adjusts it to the specified horizontal angle according to the roadway monitoring requirements. After adjustment, the limiting mechanism of the first mounting part 1 is activated to lock and fix the angle of the first adjusting component 2 to prevent displacement. The second drive component 43 is activated to drive the rotating column 42 to rotate, driving the rotating block and the safety monitoring part 44 to complete the pitch angle adjustment to adapt to the monitoring requirements of the roadway's high and low positions. After adjustment to the target angle, the telescopic rod 51 of the control limiting component 5 is extended, so that the anti-slip body 54 presses against the anti-slip sleeve 53 and locks it. At position 42 of the rotating column, the angle is fixed. After the equipment adjustment is completed, it enters the fully automatic monitoring mode. The monitoring camera 444 collects the tunnel image in real time. The temperature monitoring device 442, humidity detector, and gas detector 443 continuously collect tunnel environmental parameters 24 hours a day. All data and images are uploaded to the ground monitoring terminal in real time. Staff can remotely view the tunnel construction status and environmental safety conditions in real time, realizing unattended routine monitoring. The system has a built-in timed cleaning program, which can be set to start the drive unit 75 daily, driving the drive gear 76 and driven gear ring 73, and sliding gear. Ring 72 rotates within the annular slide rail 71, thereby driving the cleaning brush 74 to rotate and wipe the protective cover 6, removing surface coal dust and water mist. When the monitoring terminal detects that the image is blurry or the lens is obstructed, a cleaning command can be manually triggered remotely to start the cleaning unit 7 to complete the immediate cleaning and ensure the monitoring effect. During normal monitoring operation, all limit mechanisms and limit components 5 are in a locked state to ensure stable operation of the equipment. When a large range of monitoring angle adjustment is required or when the equipment needs maintenance, the telescopic rod 51 can be remotely controlled to retract, releasing the locking limit, so that the equipment angle can be freely adjusted. After maintenance is completed, it can be relocked and reset.
