Description

Technical Field

[0001] The present invention relates to the technical field of video surveillance, and more specifically, it relates to a mine monitoring camera with a built-in backup power supply. Background Art

[0002] Monitoring of cracks in mine rock walls is an important part of mine safety assessment. After coal seams are mined, gob areas are formed underground, resulting in movement and deformation of overlying strata and the generation of cracks. As the working face advances, the upward cracks in the internal crack zone of overlying strata penetrate the downward cracks on the ground surface, forming offsets; by dynamically shooting and analyzing videos and calculating the development speed of cracks, the development trend of cracks can be effectively predicted; Traditional fixed cameras are limited by the installation position, and their monitoring range is limited, making it difficult to cover irregularly extending cracks. Especially when the cracks are curved or bifurcated, monitoring blind spots are likely to occur; moreover, conventional mobile monitoring devices mostly adopt a one-way drive structure. Although they can achieve directional movement through the guide rail system, they generally lack the ability to adapt to the path, and cannot adaptively adjust the path according to the crack trend, resulting in the deviation of the camera during the monitoring of curved cracks and the distortion of image data.

[0018] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0019] Please refer to Figure 1 and Figure 2 , the present invention discloses a mine monitoring camera with a built-in backup power supply, including a transverse movement driving unit 100, a longitudinal movement driving unit 200, a mounting unit 300, and a camera unit 400. The camera unit 400 is used to take pictures of the cracks on the mine rock wall passing by. The transverse movement driving unit 100 is assembled with the mine rock wall corresponding to the crack to be detected and is used to drive the camera unit 400 to move horizontally. The longitudinal movement driving unit 200 is movably connected to the transverse movement driving unit 100 and is used to drive the camera unit 400 to move longitudinally. The mounting unit 300 is arranged on the longitudinal movement driving unit 200 and is used to movably mount the camera unit 400; When monitoring a horizontal crack, the camera unit 400 is adjusted by the longitudinal movement driving unit 200 to be aligned with one end of the horizontal crack, and then the camera unit 400 is driven by the transverse movement driving unit 100 to take pictures along the horizontal crack. The camera unit 400 makes an adaptive adjustment relative to the mounting unit 300 according to the bending direction of the horizontal crack; When monitoring longitudinal cracks, the camera unit 400 is adjusted to align with one end of the longitudinal crack through the transverse movement driving unit 100, and then the camera unit 400 is driven by the longitudinal movement driving unit 200 to take pictures along the longitudinal crack. The camera unit 400 makes an adaptive adjustment relative to the installation unit 300 according to the bending direction of the longitudinal crack.

[0020] Specifically, select the crack area to be measured, and fix the transverse movement driving unit 100 within this area, ensuring that under the combined action of the transverse movement driving unit 100 and the longitudinal movement driving unit 200, the movement range of the camera unit 400 can cover all the cracks to be measured. When monitoring transverse cracks, first use the transverse movement driving unit 100 to move the camera unit 400 to one end of the transverse crack, then use the longitudinal movement driving unit 200 to adjust the camera unit 400 to align with the end of the transverse crack, and then drive the camera unit 400 to feed along the transverse crack through the transverse movement driving unit 100. The camera unit 400 can make an adaptive adjustment relative to the installation unit 300 during the movement in the transverse crack, so that the movement path of the camera unit 400 is always consistent with the extension path of the transverse crack. When monitoring longitudinal cracks, first use the longitudinal movement driving unit 200 to move the camera unit 400 to one end of the longitudinal crack, then use the transverse movement driving unit 100 to adjust the camera unit 400 to align with the end of the longitudinal crack, and then drive the camera unit 400 to feed along the longitudinal crack through the longitudinal movement driving unit 200. The camera unit 400 can make an adaptive adjustment relative to the installation unit 300 during the movement in the longitudinal crack, so that the movement path of the camera unit 400 is always consistent with the extension path of the longitudinal crack.

[0021] It should be noted that through the cooperation of the transverse movement driving unit 100 and the longitudinal movement driving unit 200, the camera unit 400 can flexibly adjust its position to cover the monitoring requirements of transverse and longitudinal cracks, enabling the camera unit 400 to accurately align with the starting end of the crack and continuously take pictures along the extension direction of the crack, ensuring that the monitoring range of the crack is comprehensive and without omission; the camera unit 400 can make an adaptive adjustment relative to the installation unit 300 according to the bending direction of the crack during the movement, ensuring that the movement path of the camera unit 400 is always consistent with the extension path of the crack. Even if the crack is bent or irregular in shape, it can still maintain continuous and accurate monitoring of the crack, thereby improving the accuracy and reliability of crack monitoring. The adaptive adjustment function of the camera unit 400 reduces the monitoring blind area caused by the complex shape of the crack, can capture the subtle changes of the crack in real time, provides more accurate data support for the mine safety assessment, is applicable to the monitoring of cracks in different directions, and can maintain effective monitoring in the case of irregular crack shapes, enabling the camera system to adapt to the complex and changeable crack environment in the mine and having wide applicability.

[0022] In one embodiment, refer to Figure 3 , the lateral movement driving unit 100 includes a lateral movement guide rail 110 and a lateral movement slide table 120 slidably mounted on the lateral movement guide rail 110. A lateral movement motor 130 is provided on the lateral movement slide table 120. The output end of the lateral movement motor 130 is connected to a lateral movement gear disk 140. A lateral movement rack 150 meshing with the lateral movement gear disk 140 is provided on the lateral movement guide rail 110; the longitudinal movement driving unit 200 is mounted on the lateral movement slide table 120; Specifically, when it is necessary to drive the imaging unit 400 to move laterally, the lateral movement motor 130 drives the lateral movement gear disk 140 to rotate. Thus, under the meshing drive between the lateral movement gear disk 140 and the lateral movement rack 150, the entire lateral movement slide table 120 and the longitudinal movement driving unit 200 are driven to move laterally relative to the lateral movement guide rail 110, so as to realize the along-the-way imaging of the lateral crack by the imaging unit 400; Refer to Figure 4 , the longitudinal movement driving unit 200 includes a longitudinal movement guide rail 210 fixedly connected to the lateral movement slide table 120 and a longitudinal movement slide table 220 slidably mounted on the longitudinal movement guide rail 210. A longitudinal movement motor 230 is provided on the longitudinal movement slide table 220. The output end of the longitudinal movement motor 230 is connected to a longitudinal movement gear disk 240. A longitudinal movement rack 250 meshing with the longitudinal movement gear disk 240 is provided on the longitudinal movement guide rail 210; the mounting unit 300 is mounted on the longitudinal movement slide table 220; Specifically, when it is necessary to drive the imaging unit 400 to move longitudinally, the longitudinal movement motor 230 drives the longitudinal movement gear disk 240 to rotate. Thus, under the meshing drive between the longitudinal movement gear disk 240 and the longitudinal movement rack 250, the entire longitudinal movement slide table 220 and the mounting unit 300 are driven to move longitudinally relative to the longitudinal movement guide rail 210, so as to realize the along-the-way imaging of the longitudinal crack by the imaging unit 400; In addition, through the mutual cooperation of the lateral movement driving unit 100 and the longitudinal movement driving unit 200, the imaging unit 400 can be moved within the entire area to be measured, so that the starting position and the shooting path of the imaging unit 400 can be flexibly adjusted according to the extension direction of the crack.

[0023] It should be noted that through the precise control of the lateral movement driving unit 100 and the longitudinal movement driving unit 200, the imaging unit 400 can be adaptively adjusted according to the extension path of the crack, ensuring that the shooting path is always consistent with the crack path, thereby improving the accuracy and reliability of crack monitoring, especially in the case of complex crack shapes; the cooperation between the lateral movement driving unit 100 and the longitudinal movement driving unit 200 enables the imaging unit 400 to cover the entire area to be measured. Whether it is a lateral crack or a longitudinal crack, continuous and complete shooting can be achieved, improving the comprehensiveness and flexibility of crack monitoring.

[0024] Further, refer toFigure 5 The installation unit 300 includes a mounting plate 310 fixed to the longitudinal moving slide 220. An installation through groove 320 is formed on the mounting plate 310. The camera unit 400 is movably arranged in the installation through groove 320, and the camera unit 400 can adaptively deflect in the installation through groove 320 according to the extension path of the corresponding crack. Specifically, when photographing a transverse crack, during the feeding process of the camera unit 400 along the transverse crack, the camera unit 400 longitudinally offsets in the installation through groove 320 adaptively following the change of the extension path of the transverse crack. Thus, when the camera unit 400 photographs along the transverse crack, the camera unit 400 itself can also adaptively adjust following the bending direction of the transverse crack, so as to ensure that during the entire camera scanning process, the camera unit 400 can always be aligned with the crack opening below it. Similarly, when photographing a longitudinal crack, during the feeding process of the camera unit 400 along the longitudinal crack, the camera unit 400 transversely offsets in the installation through groove 320 adaptively following the change of the extension path of the longitudinal crack. Thus, when the camera unit 400 photographs along the longitudinal crack, the camera unit 400 itself can also adaptively adjust following the bending direction of the longitudinal crack, so as to ensure that during the entire camera scanning process, the camera unit 400 can always be aligned with the crack opening below it.

[0025] It should be noted that the design of the installation unit 300 allows the camera unit 400 to freely deflect in the installation through groove 320, enabling the camera unit 400 to make real-time adjustments according to the bending direction of the crack, ensuring that its shooting path is always consistent with the extension path of the crack. Whether it is a transverse crack or a longitudinal crack, the camera unit 400 can automatically adjust its posture during movement to adapt to the shape change of the crack; through adaptive deflection, the camera unit 400 can always be aligned with the crack opening below it, thereby ensuring that the captured image is clear and accurate and avoiding shooting deviation caused by crack bending.

[0026] Please refer to Figure 6 For the adaptive deflection of the camera unit 400 in the installation through groove 320, sliding grooves 330 are formed on the inner periphery of the installation through groove 320. First sliders 340 are slidably arranged in the sliding grooves 330. Sleeve rods 360 are fixed on the first sliders 340. Sleeve barrels 350 corresponding to the sleeve rods 360 are circumferentially arranged on the camera unit 400. The sleeve barrels 350 are slidably connected to the corresponding first sliders 340. First springs 370 are movably sleeved on the first sliders 340. Specifically, no matter in which direction the imaging unit 400 deviates following the crack, relative sliding can occur between two sets of opposing sleeves 350 and the corresponding first sliders 340, and at the same time, the two sets of first sliders 340 perpendicular to them slide synchronously in the corresponding chutes 330, while the other two sets of opposing sleeves 350 and first sliders 340 do not move. In this way, when performing imaging monitoring of a transverse crack, the imaging unit 400 can perform adaptive longitudinal deviation in the installation through groove 320 following the extension direction of the transverse crack, and when performing imaging monitoring of a longitudinal crack, the imaging unit 400 can perform adaptive transverse deviation in the installation through groove 320 following the extension direction of the longitudinal crack. The function of setting the first spring 370 is that when the imaging unit 400 separates from the crack, it can drive the imaging unit 400 to reset to the central position of the installation through groove 320 to realize the initialization of the imaging unit 400.

[0027] In another embodiment, please refer to Figure 6 and Figure 7 , the imaging unit 400 includes an adjustment table 410 and a mounting base 420 that is liftably arranged below the adjustment table 410, and a probe 430 for photographing the crack is installed in the mounting base 420. Specifically, when imaging the crack, the mounting base 420 is embedded in the crack so that the probe 430 is directly above the crack opening. Considering that there are also differences in the heights of different positions of the crack, when the entire imaging unit 400 feeds along the crack, the mounting base 420 can also adjust its height relative to the adjustment table 410 according to the height difference of the crack, so that the distance between the probe 430 and the crack opening is always kept constant.

[0028] It should be noted that the mounting base 420 of the imaging unit 400 can be adjusted in height according to the height difference of the crack, so that the probe 430 always maintains a constant distance from the crack opening during the crack monitoring process. Even if there are differences in the heights of different positions of the crack, it can ensure that the captured images are clear and accurate. Through the height adjustment function, the probe 430 can always be directly above the crack opening, avoiding shooting deviations caused by changes in the crack height, thereby improving the accuracy and reliability of crack monitoring. The height adjustment function of the mounting base 420 ensures that the distance between the probe 430 and the crack opening is always kept constant, reducing problems such as image blurring or distortion caused by distance changes, improving the quality and stability of the captured images, and being able to adapt to complex situations with large changes in crack height, ensuring high-precision shooting throughout the entire extension path of the crack.

[0029] In addition, considering that the entire imaging unit 400 is constantly moving during the process of photographing the crack, and the working conditions at the shooting site are complex, there are certain disadvantages in powering the imaging unit 400 only through a wired power supply. For this reason, please refer to Figure 7 A spare battery pack 440 electrically connected to the probe 430 is provided at the upper end of the mounting base 420. The spare battery pack 440 is slidably sleeved in the adjustment table 410. A plurality of limiting slide bars 441 slidably adapted to the adjustment table 410 are circumferentially arranged on the spare battery pack 440, and a limiting plate 442 is provided at the top of the spare battery pack 440; Specifically, when the external power supply is accidentally cut off, the spare battery pack 440 can still provide power for the probe 430, so as to ensure the uninterrupted shooting process of the probe 430 and improve the adaptability in complex environments; the spare battery pack 440 can move up and down synchronously with the probe 430 relative to the adjustment table 410, so as to ensure that the spare battery pack 440 always maintains a stable connection with the probe 430 during the height change of the probe 430 and improve the output stability of the backup power supply.

[0030] Furthermore, please refer to Figure 8 and Figure 9 To ensure that the probe 430 can always face the crack opening during movement, an installation cavity 421 is formed in the mounting base 420. The probe 430 is installed at the center of the top of the installation cavity 421. A through hole 422 is formed at the bottom of the installation cavity 421, and the probe 430 is located directly above the through hole 422; During the feeding process of the mounting base 420 along the crack, due to the hollow setting of the through hole 422, the crack opening and the internal area are always exposed within the shooting range of the probe 430 above the through hole 422, and the probe 430 can always maintain centered shooting with the crack; The through hole 422 in the mounting base 420 provides a stable shooting channel for the probe 430. The crack opening and the internal area are always exposed within the shooting range of the probe 430 above the through hole 422, ensuring that the probe 430 can always be aligned with the crack opening for shooting; the hollow setting of the through hole 422 and the centered installation of the probe 430 enable the probe 430 to always maintain centered shooting with the crack during movement, avoiding shooting deviation caused by position offset.

[0031] Even further, please refer to Figure 8 and Figure 9 Considering that when the mounting base 420 feeds along the extending direction of the crack, due to the bending of the crack, the mounting base 420 will randomly rub against the crack side wall, which will increase the feeding resistance of the imaging unit 400 on the one hand and exacerbate the wear of the mounting base 420 on the other hand. For this reason, a rolling ring 450 that is rotationally embedded at the bottom of the mounting base 420 and is rollingly adapted to the crack side wall is provided; Specifically, when the mounting seat 420 is fed in the crack, the rolling ring 450 on the outside of the mounting seat 420 can always roll in contact with the inner wall of the crack, so that when the mounting seat 420 passes through the bending area of the crack, the relative rolling of the rolling ring 450 and the inner wall of the crack reduces the resistance and wear of the movement of the mounting seat 420.

[0032] Also, see Figure 9 and Figure 10 Considering the complex internal environment of the mine and the large amount of floating dust, dust is easily adhered to the surface of the probe 430 during the process of photographing cracks, resulting in limited photography. Therefore, a cavity 423 is provided on one side of the mounting seat 420, and a cleaning member 460 for cleaning the probe 430 is provided in the cavity 423; when the rolling ring 450 moves, the cleaning member 460 can be driven to clean the probe 430; Specifically, see Figure 10 and Figure 11 The cleaning member 460 includes a guide rod 461 horizontally fixed in the cavity 423, a second slider 462 is slidably sleeved on the guide rod 461, and second springs 463 abutting against the second slider 462 are sleeved on both ends of the guide rod 461; a connecting frame 464 extending out of the cavity 423 is fixed on the second spring 463, and cleaning brushes 465 adapted to the probe 430 are symmetrically arranged on both sides of the extending end of the connecting frame 464; A flexible paddle 466 is disposed at the lower end of the second sliding block 462, and a plurality of paddle plates 451 adapted to the flexible paddle 466 are disposed circumferentially on the rolling ring 450; When the rolling ring 450 rotates relative to the mounting seat 420, it can drive each paddle plate 451 to rotate synchronously in the circumferential direction. When one group of paddle plates 451 contacts the flexible paddle 466, it can push the flexible paddle 466 to bend and deform to one side, and at the same time drive the second slider 462 to slide along the guide rod 461 to drive the cleaning brush 465 at the end of the connecting frame 464 to clean the probe 430, until the flexible paddle 466 bends to a certain extent and disengages from the paddle plate 451, the second slider 462 can slide and reset under the elastic force of the second spring 463, and the flexible paddle 466 also returns to its initial state; this reciprocating process, no matter what the rotation direction of the rolling ring 450 is, it can drive the corresponding cleaning brush 465 to periodically clean the probe 430.

[0033] It should be noted that the cleaning member 460 can periodically clean the probe 430 through the rotation drive of the roller ring 450. Regardless of the rotation direction of the roller ring 450, the cleaning brush 465 can clean the probe 430 to ensure that the surface of the probe 430 is always kept clean; the automatic cleaning function can effectively reduce the impact of dust on the shooting and improve the clarity and reliability of the shooting; The flexible paddle 466 cooperates with the paddle plate 451 on the rolling ring 450. When the paddle plate 451 contacts the flexible paddle 466, the flexible paddle 466 can be paddled to bend and deform, thereby driving the cleaning brush 465 to clean the probe 430. After cleaning, the flexible paddle 466 returns to its initial state under the elastic force of the second spring 463.

[0034] The specific implementation modes of the present invention are described above, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are merely illustrative and not restrictive. Under the guidance of the present invention, those skilled in the art may also make many forms, all of which are within the protection of the present invention.
