Description

Technical Field

[0001] This invention belongs to the field of monitoring equipment technology, specifically a monitoring device for underground coal mines. Background Technology

[0002] In the field of coal mine safety production, the application of video surveillance technology has become an important means to ensure operational safety and improve production efficiency. It enables remote monitoring of personnel behavior, equipment status, and environmental changes in coal mines. Among these, mobile monitoring equipment is widely used because it can implement full-process supervision and has the advantages of quick installation and portability.

[0003] An existing mobile monitoring device can be angled by a rotating mechanism and equipped with a movable vertical bracket to achieve a vertical placement, meeting flexible mobility needs. However, when used in underground coal mines, due to the long-term exposure to high-concentration dust environments, the monitoring device lens easily attracts coal dust. Dust accumulation not only directly leads to blurred monitoring images and reduced image quality, affecting real-time monitoring, but if not cleaned in time, the coal dust will gradually solidify and clump together, further increasing the difficulty of cleaning. Although a continuously moving brush can be installed on the lens surface for cleaning, it will quickly become contaminated with coal dust in the dusty environment, causing its cleaning ability to decrease significantly over time. More seriously, if small stones or other hard particles commonly found underground are mixed into the brush, they may directly scratch the lens surface during reciprocating motion, causing irreversible damage and exacerbating the risk of monitoring device malfunction.

[0004] Therefore, the present invention provides a coal mine underground monitoring device. Summary of the Invention

[0007] Preferably, the cleaning structure further includes: a sliding rod, which is disposed at one end of the monitoring body near the cleaning frame, and one end of the cleaning frame slides on the surface of the sliding rod; a screw, which is rotatably connected to one end of the monitoring body near the cleaning frame, and the other end of the cleaning frame is threadedly connected to the screw; a CNC track, which is disposed at the lower end of the monitoring body; a moving frame, which moves inside the CNC track; an abutting roller, which is disposed at the upper end of the moving frame, and abuts against the pressing block during operation; a connecting strip, which is rotatably connected inside the sliding frame, and the connecting strip is connected to the cleaning roller; and a chute, which is formed at one end of the temporary storage frame, and one end of the cleaning roller slides inside the chute.

[0008] Preferably, the lower end of the auxiliary door is rotatably connected to an abutment piece, one side of the abutment piece is provided with a limiting plate, and the limiting plate is fixedly connected to the surface of the auxiliary door. The lower end of the monitoring lens is provided with an abutment block, and the abutment piece contacts the abutment block when working.

[0009] Preferably, the lower end of the abutment piece is provided with an auxiliary spring, and one end of the auxiliary spring is connected to the auxiliary door.

[0010] Preferably, the upper end of the cleaning frame is provided with an auxiliary strip, and the auxiliary strip is in contact with the sliding frame.

[0011] Preferably, the sliding frame is provided with an auxiliary wheel at one end near the monitoring body, and the auxiliary wheel slides on the upper end of the monitoring body.

[0012] Preferably, the inside of the chute is provided with a buckle, and the buckle is engaged with one end of the cleaning roller.

[0013] Preferably, a return spring is provided at the connection between the lower baffle and the temporary storage frame.

[0014] Preferably, the lower end of the monitoring unit is provided with a water pipe, the interior of the abutment block is hollow, and the abutment block is inclined towards the end close to the water pipe, and one end of the water pipe is connected to the interior of the abutment block.

[0015] Preferably, the upper end of the base is provided with a telescopic rod, and the telescopic rod slides inside the connecting rod.

[0016] The beneficial effects of this invention are as follows: 1. The coal mine underground monitoring device of the present invention, by setting a cleaning structure, after the monitoring device has been working in the underground coal mine for a period of time, starts the screw rotation. Since one end of the cleaning frame is threadedly connected to the screw, and the other end slides on the surface of the sliding rod, the cleaning frame will move towards the monitoring lens. Then, the CNC track is activated. Since the moving frame moves inside the CNC track, the moving frame will move to the end of the CNC track near the screw. When the cleaning frame moves to the surface of the monitoring lens, the abutment piece will abut against the abutment block. Since the cleaning frame is moving at this time, and one end of the abutment piece is limited by the limiting plate, the abutment piece and the auxiliary door will be abutted by the abutment block to rotate, so that the auxiliary door at one end of the cleaning frame rotates. The auxiliary door opens, and at this time, the pressing block at the other end of the cleaning frame will also contact the abutment roller at one end of the moving frame, causing the pressing block to be pushed and moved inward into the cleaning frame, pressing the rubber water bag containing lens cleaning fluid. Since there are several abutment rollers, and each roller is spaced apart, the pressing block intermittently presses the rubber water bag. Finally, as the cleaning frame moves, the lens cleaning fluid is sprayed onto the surface of the monitoring lens through nozzles. During the spraying of the lens cleaning fluid, the connecting strip is activated, which drives the cleaning roller to rotate. Initially, the cleaning roller is located inside the temporary storage frame, reducing contamination from external coal dust. As the cleaning roller is driven by the connecting strip... At this time, the cleaning roller will first contact the lower baffle. Because a return spring is installed at the connection between the lower baffle and the temporary storage frame, the lower baffle will initially block the cleaning roller inside the temporary storage frame. Then, the lower baffle will flip, allowing the cleaning roller to move out of the temporary storage frame. After the cleaning roller has moved, the return spring will release its force, causing the lower baffle to return to its original position. The cleaning roller will then rotate to contact the monitoring lens. After the lens cleaning fluid is sprayed, the abutment plate will no longer contact the abutment block. Because a spring is installed at the connection between the auxiliary door and the cleaning frame, this spring will release its force, causing the auxiliary door to return to its original position. This prevents the rubber water bag and nozzle inside the cleaning frame from being exposed to the air, reducing pollution from external coal dust. Subsequently... The cleaning frame will continue to move, at which point the auxiliary strip at the top of the cleaning frame will contact the end of the sliding frame near the auxiliary wheel. This, in turn, will move the cleaning roller via the sliding frame. Since the cleaning roller is now in contact with the monitoring lens, and the lens surface is coated with lens cleaning fluid, the moving cleaning roller will wipe the lens, ensuring its cleanliness during operation. Upon resetting, a spring at the connection between the sliding frame and the anti-smashing cover will release its elasticity, resetting the sliding frame to allow for the subsequent placement of the cleaning roller. When operating in underground coal mines, this monitoring device can spray lens cleaning fluid onto the monitoring lens surface via the movement of the cleaning frame. After spraying, the cleaning frame can also move the cleaning roller.This process wipes the surveillance camera lens, ensuring its cleanliness during operation. Furthermore, in its initial state, the cleaning frame and roller do not affect the camera's image, and they are not initially exposed to the outside, minimizing the impact of coal dust on them. 2. The coal mine underground monitoring device of the present invention, by setting a water pipe and making the interior of the abutment block hollow, with the abutment block tilted towards the end near the water pipe, and one end of the water pipe connected to the interior of the abutment block, after the lens cleaning fluid is sprayed, the excess lens cleaning fluid will move into the interior of the abutment block, and the lens cleaning fluid will move with the tilted abutment block into the interior of the water pipe for discharge, thereby avoiding damage to the monitoring device caused by excess lens cleaning fluid.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0020] like Figures 1 to 11 As shown, an underground monitoring device for coal mines according to an embodiment of the present invention includes a base 1, a connecting rod 2 at the upper end of the base 1, an adjusting frame 21 at the upper end of the connecting rod 2, a monitoring body 3 rotatably connected to the upper end of the adjusting frame 21, a monitoring lens 31 on one side of the monitoring body 3, an anti-smashing cover 4 at the upper end of the monitoring body 3, and a cleaning structure 5 at the end of the surface of the monitoring body 3 near the monitoring lens 31; the cleaning structure 5 includes: a cleaning frame 501, which is slidably connected to the end of the surface of the monitoring body 3 near the monitoring lens 31; a rubber water bag 517, which is disposed inside the cleaning frame 501, and the surface of the rubber water bag 517 is provided with a plurality of nozzles 518; and an auxiliary door. 519, auxiliary door 519 is rotatably connected to one end of cleaning frame 501 near monitoring body 3; pressing block 515, several pressing blocks 515 are slidably connected to the side wall of cleaning frame 501, and the pressing blocks 515 are in contact with rubber water bag 517 when working; sliding frame 507, sliding frame 507 is slidably connected to the lower end of anti-smashing cover 4; cleaning roller 509, cleaning roller 509 is rotatably connected to one end of sliding frame 507; temporary storage frame 506, temporary storage frame 506 is located at the lower end of anti-smashing cover 4 near sliding frame 507, and cleaning roller 509 is located inside temporary storage frame 506 in the initial state; lower baffle 508, lower baffle 508 is rotatably connected to the lower surface of temporary storage frame 506.

[0021] Specifically, this solution involves a coal mine underground monitoring device that needs to be moved to the underground coal mine location for real-time video signal acquisition and transmission to the ground monitoring center. This allows management personnel to monitor underground operations, equipment status, and personnel activities in real time. After relocation, the angle of the monitoring unit 3 within the adjustment frame 21 can be adjusted. The monitoring unit 3 is then activated, and the monitoring lens 31 focuses the light from the complex underground scene onto the image sensor surface. The monitoring unit 3 then uses a new generation of video encoding standards to efficiently compress the data, significantly reducing the data size while retaining key information. The compressed video is then transmitted to the ground monitoring center, where it is received and processed. Hardware acceleration technology enables simultaneous decoding of multiple video feeds. The decoded video signal is then superimposed with equipment status data and output to a high-resolution display terminal, supporting multi-screen splitting and dynamic switching. This provides dispatchers with lag-free, stutter-free real-time monitoring of the mine. Due to environmental factors, after a period of operation, coal dust accumulates on the surface of the monitoring lens 31. This dust directly causes blurring of the monitoring image, reducing image quality and affecting real-time monitoring. At this point, the cleaning frame 501 is activated and moves towards the monitoring lens 31. When the cleaning frame 501 reaches the surface of the monitoring lens 31, the auxiliary door 519 opens. The nozzle 518 inside the 01 will face the monitoring lens 31, and then the pressing block 515 will be activated. The pressing block 515 will press the rubber water bag 517, which contains lens cleaning fluid. Finally, as the cleaning frame 501 moves, the lens cleaning fluid will be sprayed onto the surface of the monitoring lens 31 through the nozzle 518. During the spraying of the lens cleaning fluid, the cleaning roller 509 will be activated. The cleaning roller 509 will rotate on the surface of the sliding frame 507, and at this time the lower baffle 508 will be activated. In the initial state, the cleaning roller 509 will be located inside the temporary frame 506, thereby reducing the contamination of the cleaning roller 509 by external coal dust. When the cleaning roller 509 rotates, the cleaning roller 509 will... 9 will move out from inside the temporary frame 506. After the cleaning roller 509 has moved, it will rotate to contact the monitoring lens 31. After the lens cleaning fluid is sprayed, the auxiliary door 519 will be activated again to close, so that the rubber water bag 517 and nozzle 518 inside the cleaning frame 501 will not be exposed to the air, reducing pollution from external coal dust. At this time, the sliding frame 507 will be activated to drive the cleaning roller 509 to move. Since the cleaning roller 509 is in contact with the monitoring lens 31 and the surface of the monitoring lens 31 is coated with lens cleaning fluid, the cleaning roller 509 will wipe the monitoring lens 31 when it moves, thus ensuring the cleanliness of the monitoring lens 31 during operation.

[0022] like Figures 1 to 11As shown, the cleaning structure 5 further includes: a sliding rod 503, which is located at one end of the monitoring body 3 near the cleaning frame 501, and one end of the cleaning frame 501 slides on the surface of the sliding rod 503; a screw 502, which is rotatably connected to one end of the monitoring body 3 near the cleaning frame 501, and the other end of the cleaning frame 501 is threadedly connected to the screw 502; a CNC track 504, which is located at the lower end of the monitoring body 3; and a moving frame 511, which moves... The moving frame 511 moves inside the CNC track 504; the abutting roller 512 is located at the upper end of the moving frame 511 and abuts against the pressing block 515 during operation; the connecting strip 510 is rotatably connected inside the sliding frame 507 and is connected to the cleaning roller 509; the chute 524 is opened at one end of the temporary frame 506 and one end of the cleaning roller 509 slides inside the chute 524.

[0023] Specifically, when coal dust adheres to the surface of the monitoring lens 31, the screw 502 is activated to rotate. Since one end of the cleaning frame 501 is threadedly connected to the screw 502, and the other end slides on the surface of the sliding rod 503, the cleaning frame 501 will move towards the monitoring lens 31. Subsequently, the CNC track 504 is activated. Since the moving frame 511 moves inside the CNC track 504, the moving frame 511 will move to the end of the CNC track 504 closest to the screw 502. While the cleaning frame 501 is moving, the other end of the cleaning frame 501... The pressing block 515 will also contact the abutment roller 512 at one end of the moving frame 511, causing the pressing block 515 to be pushed and move into the cleaning frame 501, and press the rubber water bag 517, which contains lens cleaning fluid. Since there are several abutment rollers 512 and there is a certain distance between each abutment roller 512, the pressing block 515 presses the rubber water bag 517 intermittently. Finally, during the movement of the cleaning frame 501, the lens cleaning fluid is sprayed onto the surface of the monitoring lens 31 through the nozzle 518.

[0024] like Figures 1 to 8 As shown, the lower end of the auxiliary door 519 is rotatably connected to an abutment piece 514. A limiting plate 521 is provided on one side of the abutment piece 514, and the limiting plate 521 is fixedly connected to the surface of the auxiliary door 519. The lower end of the monitoring lens 31 is provided with an abutment block 505, and the abutment piece 514 contacts the abutment block 505 when working.

[0025] Specifically, when the cleaning frame 501 moves to the surface of the monitoring lens 31, the abutting piece 514 will abut against the abutting block 505. Since the cleaning frame 501 is moving at this time, and one end of the abutting piece 514 is limited by the limiting plate 521, the abutting piece 514 and the auxiliary door 519 will be abutted against by the abutting block 505 to rotate, causing the auxiliary door 519 at one end of the cleaning frame 501 to open automatically. During the reset process, since the other end of the abutting piece 514 is not limited, the abutting piece 514 will rotate, preventing the auxiliary door 519 from opening. When the abutting piece 514 does not drive the auxiliary door 519 to rotate, since there is a spring at the connection between the auxiliary door 519 and the cleaning frame 501, the spring will release its elastic force, thereby driving the auxiliary door 519 to reset.

[0026] like Figure 8 As shown, the lower end of the abutment piece 514 is provided with an auxiliary spring 522, and one end of the auxiliary spring 522 is connected to the auxiliary door 519.

[0027] Specifically, by setting an auxiliary spring 522, when the abutting piece 514 is not in contact with the abutting block 505, the auxiliary spring 522 will release its elastic force, so that the abutting block 505 is always kept in a position that can contact the abutting block 505.

[0028] like Figures 1 to 11 As shown, the upper end of the cleaning frame 501 is provided with an auxiliary strip 513, and the auxiliary strip 513 is in contact with the sliding frame 507.

[0029] Specifically, by setting the auxiliary strip 513, after the lens cleaning fluid is sprayed and the cleaning roller 509 moves to contact the monitoring lens 31, the cleaning frame 501 will continue to move. At this time, the auxiliary strip 513 located at the upper end of the cleaning frame 501 will contact one end of the sliding frame 507 and drive the sliding frame 507 to move, thereby causing the cleaning roller 509 to move.

[0030] like Figures 9 to 11 As shown, the sliding frame 507 has an auxiliary wheel 523 at one end near the monitoring body 3, and the auxiliary wheel 523 slides on the upper end of the monitoring body 3.

[0031] Specifically, by setting an auxiliary wheel 523, when the sliding frame 507 moves, the auxiliary wheel 523 at one end of the sliding frame 507 will slide on the upper end of the monitoring body 3, thereby reducing wear on the monitoring body 3.

[0032] like Figures 9 to 10 As shown, the inside of the chute 524 is provided with a buckle 525, and the buckle 525 is engaged with one end of the cleaning roller 509.

[0033] Specifically, by setting the buckle 525, in the initial state, one end of the cleaning roller 509 will be engaged with the buckle 525, thereby fixing the cleaning roller 509 to a certain extent, so that the cleaning roller 509 will not shift its position during the movement of the monitoring device.

[0034] like Figures 9 to 11 As shown, a return spring 520 is provided at the connection between the lower baffle 508 and the temporary storage frame 506.

[0035] Specifically, when the connecting bar 510 moves the cleaning roller 509, the cleaning roller 509 will first contact the lower baffle 508. Since the lower baffle 508 is connected to the temporary frame 506 with a return spring 520, the lower baffle 508 will initially block the cleaning roller 509 inside the temporary frame 506. Then the lower baffle 508 will flip, causing the cleaning roller 509 to move out of the temporary frame 506. After the cleaning roller 509 has moved, the return spring 520 will release its elasticity, thereby driving the lower baffle 508 to reset. Then the cleaning roller 509 will rotate to contact the monitoring lens 31.

[0036] like Figures 1 to 5 As shown, the lower end of the monitoring unit 3 is provided with a water pipe 516, the interior of the abutment block 505 is hollow, and the abutment block 505 is inclined towards the end near the water pipe 516. One end of the water pipe 516 is connected to the interior of the abutment block 505.

[0037] Specifically, by setting up a water pipe 516, after the lens cleaning fluid is sprayed, the excess lens cleaning fluid will move into the interior of the abutment block 505. The lens cleaning fluid will then move into the interior of the water pipe 516 along with the tilted abutment block 505 and be discharged, thereby preventing the excess lens cleaning fluid from damaging the monitoring unit 3.

[0038] like Figures 1 to 2 As shown, the upper end of the base 1 is provided with a telescopic rod 22, and the telescopic rod 22 slides inside the connecting rod 2.

[0039] Specifically, by setting up the telescopic pole 22, the height of the monitoring device can be adjusted by adjusting the position of the telescopic pole 22 inside the connecting pole 2 when the monitoring device is moved, thereby adapting to more environments.

[0040] Working Principle: During use, the device needs to be moved to the underground coal mine to collect video signals in real time and transmit them to the ground monitoring center. This allows management personnel to view the underground operations, equipment status, and personnel activities in real time. After moving the device, the angle of the monitoring unit 3 within the adjustment frame 21 can be adjusted. Then, the monitoring unit 3 is activated. At this time, the monitoring lens 31 focuses the light from the complex underground scene onto the surface of the image sensor. The monitoring unit 3 then uses a new generation of video encoding standards to efficiently compress the data, significantly reducing the data size while retaining key information. The compressed video is then transmitted. After receiving the video data at the ground monitoring center, hardware acceleration technology is used to simultaneously decode multiple video streams. The decoded video signal is then compared with... After the equipment status data is superimposed, it is output to a high-resolution display terminal, supporting multi-screen splitting and dynamic switching, providing dispatchers with a real-time monitoring image of the mine without delay or lag. Due to environmental influences, after a period of operation, coal dust will accumulate on the surface of the monitoring lens 31. This dust accumulation will directly cause the monitoring image to become blurry, reducing image quality and affecting the real-time monitoring effect. At this time, the screw 502 is started to rotate. Since one end of the cleaning frame 501 is threadedly connected to the screw 502 and the other end slides on the surface of the sliding rod 503, the cleaning frame 501 will move towards the monitoring lens 31. Then, the CNC track 504 is started. Since the moving frame 511 moves inside the CNC track 504, the moving frame... 511 will move to one end of the CNC track 504 near the screw 502. When the cleaning frame 501 moves to the surface of the monitoring lens 31, the abutting piece 514 will abut against the abutting block 505. Since the cleaning frame 501 is moving at this time, and one end of the abutting piece 514 is limited by the limiting plate 521, the abutting piece 514 and the auxiliary door 519 will be abutted against by the abutting block 505 to rotate, causing the auxiliary door 519 at one end of the cleaning frame 501 to open. At this time, the pressing block 515 at the other end of the cleaning frame 501 will also contact the abutting roller 512 at one end of the moving frame 511, causing the pressing block 515 to be pushed and moved into the cleaning frame 501, pressing the rubber water bag 517. The rubber bag 517 contains lens cleaning fluid. Because there are several abutment rollers 512, and each roller is spaced apart, the pressing block 515 intermittently presses the rubber bag 517. As the cleaning frame 501 moves, the lens cleaning fluid is sprayed onto the surface of the monitoring lens 31 through the nozzle 518. During the spraying process, the connecting strip 510 is activated, causing the cleaning roller 509 to rotate. Initially, the cleaning roller 509 is located inside the temporary storage frame 506, reducing contamination from external coal dust. When the cleaning roller 509 is driven by the connecting strip 510, it first contacts the lower baffle 508.Because a return spring 520 is provided at the connection between the lower baffle 508 and the temporary storage frame 506, the lower baffle 508 will initially block the cleaning roller 509 inside the temporary storage frame 506. Then, the lower baffle 508 will flip, causing the cleaning roller 509 to move out of the temporary storage frame 506. After the cleaning roller 509 has moved, the return spring 520 will release its elasticity, thereby causing the lower baffle 508 to return to its original position. The cleaning roller 509 will then rotate to contact the monitoring lens 31. After the lens cleaning fluid is sprayed, the abutment piece 514 will no longer contact the abutment block 505. Because a spring is provided at the connection between the auxiliary door 519 and the cleaning frame 501, this spring will release its elasticity, thereby causing the auxiliary door 519 to return to its original position, allowing the rubber inside the cleaning frame 501 to return to its original position. The glue bag 517 and nozzle 518 are not exposed to the air, reducing pollution from external coal dust. The cleaning frame 501 will then continue to move. At this time, the auxiliary strip 513 at the upper end of the cleaning frame 501 will contact the end of the sliding frame 507 near the auxiliary wheel 523, and drive the cleaning roller 509 to move via the sliding frame 507. Since the cleaning roller 509 is in contact with the monitoring lens 31, and the surface of the monitoring lens 31 is coated with lens cleaning fluid, the moving cleaning roller 509 will wipe the monitoring lens 31, ensuring its cleanliness during operation. Upon resetting, a spring is provided at the connection between the sliding frame 507 and the anti-smashing cover 4. This spring will release its elasticity, thereby resetting the sliding frame 507 for subsequent placement of the cleaning roller 509.
