Description

Technical Field

[0001] This invention belongs to the field of coal mine exploration technology, specifically, it relates to a rotary lifting coal bunker camera device for coal mines. Background Technology

[0002] Coal bunkers in underground coal mines are constructed using either poured concrete or sprayed cement mortar. The constant impact of falling coal on the bunker walls causes extensive damage, necessitating repairs. Before repairs, the extent of the damage and the required work volume must be assessed. Currently, inspecting the damage requires manual climbing onto the top grate of the bunker, which is 30 meters deep – a dangerous and unsafe condition. Furthermore, the weak light from a miner's lamp further complicates the inspection process. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a rotary lifting coal bunker camera device for coal mines, which has the advantages of high safety and convenient inspection of damage to the coal bunker wall.

The mounting base rotates in a first direction, allowing the camera component to scan the entire circumference of the coal bunker wall; simultaneously, a second direction rotation allows the lens to tilt up and down or swing horizontally, covering every segment at a vertical height.

[0009] In some embodiments, the camera assembly further includes a transparent baffle located between the lens of the camera component and the sidewall of the coal mine shaft.

[0010] In some embodiments, the transparent baffle is detachably connected to the mounting base.

[0011] In some embodiments, there are multiple transparent baffles arranged sequentially along the circumference of the camera component, and the top plate has multiple ventilation holes.

[0012] In some embodiments, the camera component further includes a second driving member and a third driving member, both of which are connected between the base plate and the top plate, and are used to drive one of the base plate and the top plate to rotate about a second direction.

[0013] In some embodiments, the camera component further includes a first base and a second base, the output shaft of the second drive member is rotatably connected to the first base, the third drive member is rotatably connected to the second base, and one of the second drive member and the third drive member is movable relative to the base plate.

[0014] In some embodiments, one of the first base and the second base has a mating groove, the extension direction of the mating groove being consistent with the length direction of the base plate, one of the second driving member and the third driving member rotating about the second direction, and the other of the second driving member and the third driving member rotating about the second direction and movable along the extension direction of the mating groove.

[0015] In some embodiments, the rotary lifting coal bunker camera device for coal mines according to the present invention further includes a lighting component, which is connected to the mounting base and is located on the side of the mounting base adjacent to the lens of the camera component.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1 and Figure 2 As shown, the rotary lifting coal bunker camera device for coal mines according to an embodiment of the present invention includes a camera component 1 and a drive component.

[0022] The camera assembly 1 includes a mounting base 11 and a camera component 12. The camera component 12 is mounted on the mounting base 11 and is arranged facing the side wall of the coal mine shaft. At least one of the camera component 12 and the mounting base 11 is rotatable about a first direction and a second direction. The first direction is parallel to the height direction of the coal mine shaft and orthogonal to the second direction. The drive assembly includes a first drive component 2, which is connected to the mounting base 11 for driving the mounting base 11 to rotate about the first direction.

[0023] like Figure 1 and Figure 2 As shown, the camera assembly 1 includes a mounting base 11 and a camera component 12. The camera component 12 is fixedly connected to the mounting base 11 or connected via a rotatable structure, and the lens of the camera component 12 is arranged facing the side wall of the coal mine shaft (coal bunker).

[0024] The drive assembly includes a first drive component 2 (e.g., a combination of a motor and a reducer), which is mechanically connected to the mounting base 11 (via a shaft, coupling, gear transmission, or worm gear mechanism) to drive the mounting base 11 to rotate about a first direction.

[0025] It is understandable that the first direction is parallel to the height direction of the coal mine shaft (i.e., Figure 1 (Up and down direction in the middle). The mounting base 11 can rotate around this direction under the drive of the first driving component 2, so that the entire camera assembly 1 can achieve circumferential scanning around the coal bunker wall.

[0026] The second direction is orthogonal to the first direction (i.e.) Figure 1 (Left and right directions). At least one of the camera component 12 and the mounting base 11 can rotate about the second direction. The camera component 12 can rotate about the second direction relative to the mounting base 11 (e.g., by a built-in micro motor or manual adjustment mechanism); or the mounting base 11 itself has the ability to rotate in the second direction (in which case an additional second drive component may be required, or it may be achieved by a composite transmission mechanism).

[0027] The rotary lifting coal bunker camera device of this invention allows the camera component 12 to be remotely controlled to be raised, lowered, or placed inside the coal bunker, eliminating the need for personnel to climb over the coal bunker grate or descend into the bunker for inspection. The mounting base 11 rotates in a first direction, enabling the camera component 12 to scan the entire circumference of the coal bunker wall; simultaneously, rotation in a second direction allows the lens to tilt up and down or swing horizontally, covering every segment at vertical height. Through the image data transmitted by the camera component 12, ground operators can repeatedly view and measure the damaged area, shape, and location, thereby assisting construction personnel in accurately calculating the required material quantity and construction plan for repairs.

[0028] In some embodiments, the mounting base 11 includes a base plate 111 and a top plate 112. The top plate 112 is connected to the first driving component 2, and the camera component 12 is connected to the base plate 111. In the height direction of the coal mine shaft, the camera component 12 is located between the top plate 112 and the base plate 111.

[0029] like Figure 1 and Figure 2 As shown, the mounting base 11 consists of a top plate 112 and a bottom plate 111, with a certain distance between them to form a stable frame or cavity. The top plate 112 is directly and fixedly connected to the output end (such as a shaft or flange) of the first drive component 2. The bottom plate 111 is used to fix the camera component 12 (e.g., by bolts, clips, or a special bracket).

[0030] Understandably, the camera component 12 is located between the top plate 112 and the bottom plate 111, which makes the center of gravity of the entire rotating assembly close to the rotation center (the rotation axis of the top plate 112), reducing the moment of inertia, reducing the power requirement of the first drive component 2, and making the rotation more stable, reducing vibration caused by eccentricity.

[0031] The top plate 112 and the bottom plate 111 form a structure similar to a protective shell. When coal falls into the coal bunker, dust falls, or there is an accidental collision, the top plate 112 and the bottom plate 111 can effectively block foreign objects from directly hitting the camera component 12 from above and below (especially since coal blocks often fall into the coal bunker, the top plate 112 plays a shielding role).

[0032] In some embodiments, the camera assembly 1 further includes a transparent baffle 13 located between the lens of the camera component 12 and the side wall of the coal mine shaft.

[0033] like Figure 1 and Figure 2 As shown, the transparent baffle 13 can be made of a high-strength transparent material (such as tempered glass, polycarbonate, or mining explosion-proof plexiglass). The transparent baffle 13 can be directly fixed to the base plate 111 of the mounting base 11 or the housing of the camera component 12, located directly in front of the lens, and connected by sealing strips, bolts, or slots to ensure that there is a small gap between it and the lens to avoid direct contact.

[0034] If the camera component 12 can tilt and rotate in the second direction, the transparent baffle 13, when fixed to the housing of the camera component 12, will rotate synchronously with the lens, always maintaining the same relative position with the lens. Of course, the transparent baffle 13 can also be fixed to the side wall of the mounting base 11 by an independent bracket, in which case the size of the baffle needs to cover all possible orientations of the lens.

[0035] In other words, the constant impact of falling coal in the coal bunker means that coal chunks or particles may strike the camera component 12 at high speed. As a precision optical component, if the lens is cracked or scratched, it will directly lead to imaging failure and high repair costs. The transparent baffle 13 acts as a sacrificial layer, absorbing the impact force first, preventing direct damage to the lens, extending the service life of the camera component 12, and reducing the frequency of downtime and maintenance due to accidental impacts.

[0036] In some embodiments, the transparent baffle 13 is detachably connected to the mounting base 11. The transparent baffle 13 can be detachably connected to the mounting base 11 by means of bolts / screws, snap-locking structures, clamping / pressing structures, etc.

[0037] Understandably, coal dust concentrations are extremely high in underground coal mines, and coal dust can easily cover lenses, causing image blurring or even complete image failure. The transparent baffle 13 blocks the coal dust, and routine maintenance only requires wiping the outer surface of the baffle, eliminating the need for frequent disassembly of the precision lens. This significantly reduces maintenance workload and increases the continuous operating time of the equipment.

[0038] In some embodiments, there are multiple transparent baffles 13 arranged sequentially along the circumference of the camera component 12, and the top plate 112 has multiple vent holes. These vent holes can be evenly distributed on the surface of the top plate 112, or they can be a ring of small holes arranged around the central axis. The vent holes directly connect the interior of the mounting base 11 (the space between the top plate 112 and the bottom plate 111) to the external environment, facilitating the discharge of heat from the transparent baffles 13. Furthermore, dustproof mesh (metal wire mesh or sintered filter) is provided inside or at the openings of the holes to prevent excessive coal dust from entering.

[0039] Understandably, a complete transparent protective cover is divided into several segments (e.g., 3 or 4 pieces) along the circumference, and each baffle is independently fixed to the base plate 111 or side wall of the mounting base 11 by a slot or bolt. Sealing strips are provided at the joints between the baffles to prevent coal dust from entering through the gaps. If the camera component 12 has multiple lenses (e.g., a panoramic multi-view camera) or requires focused observation of different directions, transparent baffles 13 can be installed in front of each lens, with each baffle evenly distributed along the circumference of the mounting base 11.

[0040] In other words, the direction in which coal falls from the coal bunker is not fixed; coal chunks may fall from directly above or bounce off the coal wall and fly from the side. By using multiple transparent baffles 13 arranged circumferentially, a physical barrier is formed around the lens. No matter the angle from which the coal hits the camera component 12, the transparent baffles 13 will absorb the impact first. Compared to a single baffle protecting only one direction, this design significantly reduces the risk of accidental impact to the lens. Especially when the device rotates or moves up and down within the coal bunker, the lens orientation constantly changes, and circumferential protection ensures protection regardless of the angle of rotation.

[0041] In some embodiments, the camera component 12 further includes a second drive member 14 and a third drive member 15, both of which are connected between the base plate 111 and the top plate 112. The second drive member 14 and the third drive member 15 are used to drive one of the base plate 111 and the top plate 112 to rotate about a second direction.

[0042] like Figure 1 and Figure 2 As shown, both drive components are installed in the space between the base plate 111 and the top plate 112, with their ends connected to the base plate 111 and the top plate 112 respectively. That is, the fixed end of the drive component (such as the motor housing) is fixed to one of the top plate 112 or the base plate 111, and its movable end (such as a push rod or a rotating shaft) is connected to the other plate; or, the two drive components are arranged symmetrically to jointly support the gap between the base plate 111 and the top plate 112 and to work together to generate a relative rotation angle around the second direction (horizontal direction).

[0043] The second drive member 14 and the third drive member 15 are used to drive one of the base plate 111 and the top plate 112 to rotate about a second direction. When one of the drive members extends, retracts, or rotates, it forces the base plate 111 to pitch or oscillate relative to the top plate 112 (or the top plate 112 relative to the base plate 111). Typically, the top plate 112 is directly connected to the first drive member 2 (i.e., the top plate 112 is fixed on the rotation axis), so the base plate 111 is the movable end. The two drive members work together to make the base plate 111 rotate about a second direction (horizontal axis) orthogonal to the first direction, thereby changing the pitch angle of the camera member 12 fixed on the base plate 111.

[0044] Optionally, if the second drive member 14 and the third drive member 15 are linear drive members (such as electric push rods or lead screw nuts), the two drive members are arranged in parallel or cross directions, with one extending and the other shortening, which can generate rotation around a certain horizontal axis; if they are rotary drive members (such as a combination of stepper motor and reducer), the output shafts of the two drive members can be hinged to the base plate 111 or the top plate 112 through gears, connecting rods and other mechanisms to achieve bidirectional swing.

[0045] In other words, the first drive component 2 rotates the mounting base 11 around the vertical direction, enabling panoramic scanning, but it cannot change the pitch angle of the camera component 12. With the addition of the second drive component 14 and the third drive component 15, the base plate 111 can swing relative to the top plate 112 around the horizontal axis, allowing the lens to tilt up and down. This allows operators to not only observe the circumferential direction of the coal bunker wall but also adjust the height of the viewing angle for more detailed inspection of damaged areas on the coal bunker wall. For example, when a damaged area requires close observation, the second and third drive components 15 can tilt the lens downwards or upwards at a certain angle to obtain a clearer image.

[0046] In some embodiments, the camera component 12 further includes a first base 16 and a second base 17, the output shaft of the second drive member 14 is rotatably connected to the first base 16, the third drive member 15 is rotatably connected to the second base 17, and one of the second drive member 14 and the third drive member 15 is movable relative to the base plate 111.

[0047] like Figure 1 and Figure 2 As shown, the first base 16 and the second base 17 are fixed to the base plate 111 (or integrally formed with the base plate 111) and serve as the free end support points of the output shaft of the drive component. Optionally, the first base 16 and the second base 17 can be bosses, brackets or independently machined blocks on the base plate 111, and are fixed to the base plate 111 by bolts or welding.

[0048] The output shaft (such as a motor shaft or push rod end) of the second drive element 14 is rotatably connected to the first base 16, for example, through a hinge, ball joint, or bearing. This allows the output shaft to rotate freely relative to the first base 16, but its axial position is restricted.

[0049] One of the second driving member 14 and the third driving member 15 is movable relative to the base plate 111. That is, the housing of one of the driving members is connected to the base plate 111 via a slide rail and a guide groove, and can slide in a certain direction (e.g., parallel to the plane of the base plate 111); or, the fixed end of one of the driving members is mounted on a translatable slider, and a guide mechanism is provided between the slider and the base plate 111; or, one of the driving members is connected to the base plate 111 via a spring or elastic support to allow a small amount of elastic displacement.

[0050] In some embodiments, one of the first base 16 and the second base 17 has a mating groove 18, the extension direction of the mating groove 18 is consistent with the length direction of the base plate 111, one of the second drive member 14 and the third drive member 15 rotates about a second direction, and the other of the second drive member 14 and the third drive member 15 rotates about the second direction and is movable along the extension direction of the mating groove 18.

[0051] It is understandable that, such as Figure 1 and Figure 2 As shown, both the first base 16 and the second base 17 are fixed to the base plate 111 of the mounting base 11 (either integral with the base plate 111 or connected by bolts). One of them (e.g., the first base 16) has a mating groove 18, the longitudinal direction of which is parallel to the length direction of the base plate 111 (i.e., along the longest side of the base plate 111). The mating groove 18 can be a through groove or a closed groove, with a smooth inner surface or a guide rail to guide the sliding parts.

[0052] The output shaft of one of the driving components (the third driving component 15) is rotatably connected to the corresponding base (the one without the mating groove 18) by means of a hinge or ball joint, allowing it to rotate freely about a second direction, but with its radial and axial positions fixed.

[0053] The output shaft of the other drive unit (second drive unit 14) is also rotatably connected to another base (the one with the mating groove 18), but the entire second drive unit 14 or the slider at the end of its output shaft can slide freely along the extension direction of the mating groove 18. That is to say, in addition to being able to rotate around the second direction, the second drive unit 14 also has an additional degree of freedom to translate along the direction of the mating groove 18.

[0054] When the two driving components work together, the third driving component 15 fixes its base position, and the second driving component 14 slides within the mating groove 18, causing the base plate 111 to tilt relative to the top plate 112 about the second direction (horizontal axis). The length of the mating groove 18 limits the maximum tilt angle of the base plate 111, while releasing any over-constrained displacement that may occur in the length direction of the base plate 111.

[0055] In some embodiments, the rotary lifting coal bunker camera device for coal mines according to the present invention further includes a lighting component, which is connected to the mounting base 11 and is located on the side of the mounting base 11 adjacent to the lens of the camera component 12.

[0056] like Figure 1 and Figure 2As shown, the lighting assembly can be fixed to the base plate 111, top plate 112, or side wall of the mounting base 11, with the specific location flexibly selected according to the actual structure. Since this embodiment explicitly requires the lighting assembly to be located on the side of the mounting base 11 adjacent to the lens of the camera component 12, the most common installation method is to fix it to the front edge of the base plate 111 (i.e., the end in the direction of lens extension), or to the bracket around the transparent baffle 13, so that the lighting light is basically consistent with the direction of the lens optical axis.

[0057] Optionally, the lighting assembly typically includes one or more light sources (such as high-brightness LED chips, a ring LED array, or a mining explosion-proof searchlight) and is equipped with corresponding power cables, heat dissipation structures, and explosion-proof housings. The illumination direction of the light source can be designed to be fixed (in the same direction as the lens), or an independent adjustment mechanism (such as a universal joint) can be added to adapt to the supplementary lighting needs at different angles.

[0058] In other words, the lighting components are positioned close to the lens, providing a stable, sufficient, and directionally controllable artificial light source for the camera component 12. This allows the lens to acquire bright and clear images even in the dim environment deep within the coal bunker. This directly replaces the lighting function of a manual miner's lamp, while providing a much higher lighting intensity than a handheld miner's lamp, and it does not cause light spot shifting due to hand-held shaking.

[0059] In some embodiments, the lighting assembly includes a plurality of lighting elements 3, which are respectively connected to the base plate 111 and the top plate 112.

[0060] like Figure 1 and Figure 2 As shown, one part of the lighting element 3 is directly fixedly connected to the base plate 111 (it can be fixed to the front edge, sides or bottom surface of the base plate 111 by bolts, brackets or embedding), while the other part of the lighting element 3 is fixedly connected to the top plate 112 (it can be installed on the edge, lower surface or preset mounting holes of the top plate 112). The two parts of the lighting element 3 form a layer in height and together constitute the lighting assembly.

[0061] During the pitching motion of the bottom plate 111, the illumination element 3 on it always aligns with the lens orientation, providing close-range, high-brightness frontal illumination to the coal wall area directly in front of the lens, ensuring that damage details are clearly visible. Due to its height advantage, the illumination element 3 on the top plate 112 can illuminate higher parts of the coal wall or supplement insufficient light at the top when the lens is viewed from above, preventing dark areas from appearing in the top area due to changes in the lens's pitch angle. The two illumination elements 3 work together to ensure that the area viewed by the lens receives uniform and sufficient illumination at different pitch angles, significantly reducing the differences in shadows and light spots caused by single-height illumination.
