[0002] In the construction of intelligent mines, the efficient utilization of energy and sustainable development are of crucial importance. As a clean energy technology, photovoltaic power generation has been widely applied to mine surface facilities to reduce traditional energy consumption and carbon emissions. However, the light energy conversion efficiency of existing ground photovoltaic panels is limited by the fixed installation mode and cannot dynamically adapt to the change of the sun's position, resulting in low light absorption rate, difficult self-cleaning, and unstable power generation efficiency. Especially under the complex terrain and changeable climate conditions of mines, the limitations of traditional photovoltaic systems are more prominent.

[0003] In related technologies, although there are some photovoltaic tracking devices and control systems on the market that can adjust the panel angle through single-axis or double-axis rotation, they generally have problems such as complex structure, high cost, and poor environmental adaptability, and are difficult to meet the requirements of mine scenarios for reliability, durability, and economy. In addition, existing tracking systems mostly rely on high-precision sensors or complex algorithms and are prone to failure in harsh environments such as mine dust and vibration, resulting in high maintenance costs.

[0054] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0055] As shown in the figure, the green intelligent lighting system for intelligent mines in the embodiments of the present invention includes: a lighting unit, a photovoltaic unit and a control unit.

[0056] The lighting unit 100 includes a lighting frame 101 and a lighting part 102. The lighting frame 101 is used to be installed on the ground, and the lighting part 102 is connected to the lighting frame 101. The photovoltaic unit 20 includes a first adjustment part 201, a second adjustment part 202 and a photovoltaic part 5. The first adjustment part is connected to the lighting frame 101, and the first adjustment part is rotatable around the circumference of the lighting frame 101. The second adjustment part 202 is connected to the first adjustment part 201. The photovoltaic part 5 is connected to the second adjustment part 202. The second adjustment part 202 has an unfolded state and a folded state. In the unfolded state, the plane where the photovoltaic part 5 is located is orthogonal to the direction of sunlight. In the folded state, the extension direction of the photovoltaic part 5 is parallel to the extension direction of the first adjustment part. The control unit is electrically connected to the photovoltaic unit, and the control unit is used to detect the posture of the photovoltaic part. The first adjustment part and the second adjustment part adjust the dynamic angle between the normal of the photovoltaic part 5 and the sunlight according to the posture, and the dynamic angle is less than or equal to 1°.

[0057] Specifically, Figures 1 - 9 As shown, the lighting frame 101 can be installed on the ground by bolts or ground casting to provide a support foundation for the entire system. The lighting unit 102 is connected to the lighting frame 101, and the specific connection method can be bolts, welding, etc., so that the lighting unit 102 can be stably installed on the lighting frame 101, thereby realizing the lighting function.

[0058] The first adjusting member is connected to the lighting frame 101 and can rotate around the lighting frame 101. The first adjusting member and the lighting frame 101 can be connected by a bearing or the like, so that the first adjusting part 201 can flexibly rotate around the lighting frame 101 to track the sun's position.

[0059] The second adjusting part 202 is connected to the first adjusting part 201, so that the second adjusting part 202 can move with the rotation of the first adjusting part 201, and the second adjusting part 202 itself also has a specific movement ability, that is, the conversion from the unfolded state to the folded state, so that the angle between the photovoltaic part 5 and the sunlight can be adjusted according to the use environment to ensure the power generation efficiency of the photovoltaic part 5. In addition, the photovoltaic part 5 can be folded and rotated to a safer side of the lighting frame 101 at night or in a harsh environment by using the first adjusting part 201 and the second adjusting part 202, so as to avoid the photovoltaic part 5 from being damaged by the external environment, thereby extending the service life of the photovoltaic part 5. Among them, the photovoltaic part 5 includes a plurality of photovoltaic panels and a photovoltaic panel controller, so that the electricity generated by the photovoltaic panels can be collected and transmitted to other electrical equipment, such as the lighting unit 100, the cleaning unit, etc.

[0060] It can be understood that the control unit can adjust the attitude of the photovoltaic panel in real time according to the actual sunlight, so that the photovoltaic panel can have sufficient sunlight time. That is, when the dynamic angle between the normal line of the photovoltaic panel and the sun rays is less than or equal to 1°, it means that the photovoltaic panel is almost always facing the sun. The sunlight can shine on the photovoltaic panel at an almost perpendicular angle, so that the effective area of the photovoltaic panel receiving sunlight reaches the maximum. According to the optical principle and photovoltaic effect, the photovoltaic panel absorbs the most light energy when irradiated vertically, and can convert more light energy into electrical energy, thus significantly improving the power generation efficiency. Compared with the traditional fixed-mounted photovoltaic panel, its low light absorption rate limits the power generation efficiency, while this system can effectively avoid energy loss caused by poor light angles through precise control of the dynamic angle.

[0061] Thus, through electrical connection, the intelligent green lighting system for intelligent mines in the embodiments of the present invention enables the control unit to obtain the status information of the photovoltaic part and the adjustment components in real time, realizing precise control of the photovoltaic unit. The dynamic angle between the normal line of the photovoltaic part and the sun rays is precisely adjusted to make the photovoltaic part always as perpendicular as possible to the sun rays, maximizing the absorption of sunlight and greatly improving the light energy conversion efficiency, solving the problems of low light absorption rate and unstable power generation efficiency of the existing ground photovoltaic parts due to the fixed installation mode.

[0062] In some embodiments, the control unit includes a first control component and a second control component. The first control component is connected to the photovoltaic part. The first control component includes a light detection component, and the light detection component is used to detect the light intensity and the sun incident angle. The second control component is connected to the second adjustment part. The second control component includes an angle detection component, and the angle detection component is used to detect the tilt angle of the photovoltaic part.

[0063] It can be understood that, as shown in the figure, the first control component is connected to the photovoltaic part so that the first control component can obtain the light-related information around the photovoltaic part in real time. The light detection component can be installed on the edge or surface of the photovoltaic panel to ensure that the light intensity and the sun incident angle can be accurately detected.

[0064] Optionally, the light detection component generally consists of a light intensity sensor S1 and an incident angle sensor S2. The light intensity sensor S1 obtains the light intensity data of the current environment by sensing the intensity of light. It can convert the light signal into an electrical signal and then transmit it to the control unit for processing. The incident angle sensor S2 uses the optical principle or mechanical principle to detect the sun incident angle. For example, some angle sensors use an array of multiple photosensitive elements, and calculate the incident angle of the sun relative to the photovoltaic panel by comparing the light intensity differences received by different photosensitive elements.

[0065] As shown in the figure, the second control component is connected to the second adjustment part, and this connection enables the second control component to monitor the tilt angle of the photovoltaic part in real time. The angle detection component is usually installed at the connection part between the second adjustment part and the photovoltaic part, or directly installed on the photovoltaic part to accurately measure the tilt angle of the photovoltaic part relative to the initial position.

[0066] Optionally, the angle detection component can be implemented using a variety of technologies, such as gyroscopes, accelerometers, etc. Preferably, the angle detection component is an inclination sensor Q1. The inclination sensor Q1 can convert the detected angle data into an electrical signal and transmit it to the control unit.

[0067] Optionally, the control unit further includes a wind speed sensor S3. The wind speed sensor S3 is connected to the second adjustment part so as to be able to monitor the wind speed in the mine environment in real time and accurately. In a complex and changeable environment such as a mine, the wind speed is constantly affected by various factors such as terrain and climate. By continuously monitoring the wind speed, the system can timely obtain the dynamic information of the wind speed in the current environment.

[0068] In addition, based on the monitored wind speed data, the wind speed sensor S3 feeds back the information to the control unit. The control unit will adjust the working state of the second adjustment part according to the preset logic and algorithm, combined with the wind speed situation, and then change the attitude of the photovoltaic part. When the wind speed is small, the photovoltaic part can be maintained at the optimal light receiving angle to ensure the power generation efficiency; when the wind speed increases to a certain extent, the system will make corresponding adjustments.

[0069] In some embodiments, the green intelligent lighting system for intelligent mines in the embodiments of the present invention further includes a cleaning unit. The cleaning unit includes a cleaning part 401 and a dust removal part 402. The cleaning unit is connected to at least one of the lighting unit 100 and the photovoltaic unit 20. The cleaning part 401 is arranged adjacent to the photovoltaic part 5 for spraying cleaning liquid onto the photovoltaic part 5. The dust removal part 402 is located below the cleaning part 401 in the height direction of the lighting frame 101. The photovoltaic part 5 is electrically connected to the lighting part 102 and the cleaning unit to provide the required electrical energy.

[0070] It can be understood that the cleaning unit can be connected to the lighting unit 100, or the cleaning unit can be connected to the photovoltaic unit 20, or a part of the cleaning unit is connected to the lighting unit 100 and the other part is connected to the photovoltaic unit 20. That is to say, according to the actual installation situation, the cleaning unit can be installed as a whole or installed separately to avoid excessive load on a single structure in the system. The cleaning part 401 is adjacent to the photovoltaic part 5, which can ensure that the cleaning part 401 can be stably installed in a suitable position, making it more convenient for the cleaning part 401 to spray cleaning liquid onto the photovoltaic part 5. Among them, the connection method can be fixed through pipelines, brackets, etc. The dust removal part 402 is located below the cleaning part 401 in the height direction of the lighting frame 101, and the two may be connected to the lighting frame 101 through the same bracket or pipeline system to ensure the structural stability of the entire cleaning unit.

[0071] In some embodiments, the first adjustment part 201 includes a connection disk 1, a first connection seat 2, a connecting rod 3, and a second connection seat 4. The connection disk 1 is connected to the lighting frame 101. The first connection seat 2 includes a first fixed seat 21 and a first movable seat 22. The first fixed seat 21 is fixedly connected to the connection disk 1. The first movable seat 22 is rotationally assembled on the first fixed seat 21 and connected to the connecting rod 3. The second connection seat 4 includes a second fixed seat 41, a second movable seat 42, and a rotating shaft 43. The second fixed seat 41 is connected to the connecting rod 3. The second movable seat 42 is swingably assembled on the second fixed seat 41 through the rotating shaft 43. The extending direction of the rotating shaft 43 is perpendicular to the extending direction of the rotation axis of the first movable seat 22. The second adjustment part 202 is connected to the second movable seat 42.

[0072] As Figures 1 - 11 shown, when the light source changes, the rotation of the first movable seat 22 relative to the first fixed seat 21 can drive the connecting rod 3 and the second fixed seat 41 to move. At the same time, according to the irradiation angle of the light source, the second movable seat 42 can swing relative to the second fixed seat 41 around the rotating shaft 43, thereby adjusting the pitching angle of the second movable seat 42 and the photovoltaic part 5, realizing further adjustment of the photovoltaic part 5, which is safe and reliable. That is to say, the green intelligent lighting system for intelligent mines in the embodiments of the present invention can adjust the position and inclination angle of the photovoltaic panel in real time to realize the tracking of the light source, ensure the light absorption rate and the best power generation efficiency of the photovoltaic panel, with a simple structure, strong applicability and controllable cost.

[0073] In some embodiments, the green intelligent lighting system for intelligent mines according to the embodiments of the present invention further includes a first driving assembly 6. The first driving assembly 6 includes a first driving motor 61, a transmission shaft 62, a first bevel gear 63, and a second bevel gear 64. The transmission shaft 62 is fixedly arranged on the first movable seat 22 and is rotationally matched with the first fixed seat 21. The first driving motor 61 is fixedly arranged on the first fixed seat 21. The first bevel gear 63 is arranged at the output end of the first driving motor 61. The second bevel gear 64 is arranged on the transmission shaft 62 and is in meshing transmission with the first bevel gear 63.

[0074] Specifically, the first driving motor 61 is fixedly arranged on the first fixed seat 21, and the output shaft of the first driving motor 61 is parallel to the plane where the first fixed seat 21 is located. The transmission shaft 62 passes through the first fixed seat 21 and is rotationally matched with the first fixed seat 21 through a bearing. The transmission shaft 62 is fixedly connected to the first movable seat 22. The first bevel gear 63 is installed on the output end of the first driving motor 61 through a key. The second bevel gear 64 is correspondingly arranged on the transmission shaft 62 opposite to the first bevel gear 63. When the first driving motor 61 operates, the first bevel gear 63 and the second bevel gear 64 transmit power to the transmission shaft 62 and the first movable seat 22 through meshing transmission, thereby driving the second movable seat 42 to rotate relative to the first movable seat 22. The structure is simple, safe, and reliable.

[0075] The first connecting seat 2 includes a base 23. The base 23 includes a connecting plate 231, a supporting horizontal plate 232, and supporting side plates 233. The cross-section of the connecting plate 231 is U-shaped and is detachably connected to the connecting disk 1. The supporting horizontal plate 232 and the supporting side plates 233 are arranged on the side of the connecting plate 231 away from the opening and are fixedly connected to the first fixed seat 21. There are two supporting side plates 233, and together with the supporting horizontal plate 232, they define an installation cavity for installing the first driving motor 61.

[0076] Specifically, as Figures 1 - 7 shown, the base 23 includes a connecting plate 231, a supporting horizontal plate 232, and supporting side plates 233. The connecting plate 231 includes two first plates arranged horizontally and a second plate arranged vertically connecting the two first plates. There are base 23 holes corresponding to the connecting seat on the first plates. By installing connecting bolts in the base 23 holes, the detachable connection between the base 23 and the connecting seat is realized, which is convenient for repairing and replacing individual components, reduces the maintenance cost. The supporting side plates 233 are inclined on one side of the connecting plate 231, and the supporting horizontal plate 232 is horizontally arranged between the two supporting side plates 233. While defining an installation cavity for installing the first driving motor 61 between the supporting side plates 233, the supporting side plates 233 located below the supporting horizontal plate 232 play the role of rib plates, strengthening the overall structural strength of the base 23 and ensuring the stability of the device during use.

[0077] Optionally, one end of the first plate away from the second plate is an arc surface, and the diameter of the circle corresponding to the arc surface is equal to the inner diameter of the connecting seat. By setting the side surface of the first plate as an arc surface, the area of the first plate can be increased under the condition of a certain size of the connecting seat, thereby increasing the connection strength between the base 23 and the connecting seat.

[0078] In some embodiments, the green intelligent lighting system for intelligent mines in the embodiments of the present invention further includes a second driving assembly 7. The second driving assembly 7 includes a second driving motor 71, a driving gear 72, and a transmission pendulum wheel 73. The second driving motor 71 is arranged on the second fixing seat 41, the driving gear 72 is arranged at the output end of the second driving motor 71, and the transmission pendulum wheel 73 is coaxially arranged on the rotating shaft 43 and meshes with the driving gear 72 for transmission.

[0079] Specifically, as Figures 1 - 7 shown, the second fixing seat 41 includes a first connecting member 202 and a second connecting member 203. The first connecting member 202 includes a third plate and two fourth plates vertically arranged on the third plate. The two fourth plates are connected to the connecting rod 3. The second driving motor 71 is arranged in the cavity limited by the third plate and the two fourth plates. The output shaft of the second driving motor 71 passes through the fourth plate and is rotationally matched with the fourth plate. The driving gear 72 is fixedly arranged on the output shaft of the second driving motor 71. The second connecting member 203 includes a fifth plate and two sixth plates vertically arranged on the fifth plate. The rotating shaft 43 is rotationally matched in the two sixth plates, and one end of the rotating shaft 43 passes through the sixth plate. The transmission pendulum wheel 73 is fixedly arranged on the rotating shaft 43 and meshes with the driving gear 72. The operation of the second driving motor 71 drives the transmission pendulum wheel 73 to rotate, thereby driving the rotating shaft 43 and the second movable seat 42 to rotate, and the transmission is reliable.

[0080] In some embodiments, the transmission pendulum wheel 73 includes a gear rack and a plurality of meshing teeth. The gear rack is fan-shaped and the central angle corresponding to the gear rack is not greater than 180°. The plurality of meshing teeth are equally spaced on the arc side of the gear rack and mesh with the driving gear 72.

[0081] It can be understood that, as Figures 1 - 7 shown, the transmission pendulum wheel 73 is set in the form of a gear rack and meshing teeth. The structure of the transmission pendulum wheel 73 is optimized under the condition that the swinging angle of the second movable seat 42 relative to the second fixing seat 41 is certain, thereby reducing the situation that the transmission pendulum wheel 73 is interfered by other components during use, and it is safe and reliable.

[0082] In some embodiments, limiting blocks are respectively arranged on the circumferential two sides of the gear rack. The limiting blocks are used for anti-rotation cooperation with the driving gear 72. The limiting blocks extend along the radial direction of the gear rack, thereby preventing the transmission pendulum wheel 73 from disengaging from the meshing with the driving gear 72 when rotating to both ends, and ensuring the reliability of the transmission.

[0083] In some embodiments, the second movable seat 42 includes a support plate, support lugs, and connecting lugs. The support lugs are fixedly provided on the support plate and two of them are arranged in parallel at intervals along the first direction of the support plate. The second movable seat 42 is fixedly connected to the rotating shaft 43 through the support lugs. The connecting lugs are fixedly provided on the support plate and two of them are arranged in parallel at intervals along the second direction of the support plate. The second direction is perpendicular to the first direction. A plurality of mounting oblong holes are provided on the connecting lugs. The second movable seat 42 is detachably connected to the support frame by installing connecting bolts in the mounting oblong holes, which is convenient for disassembly.

[0084] In some embodiments, as Figures 1 - 7 shown, the connecting disk 1 includes a plurality of splicing units 11. The splicing unit 11 includes a sector ring plate and a cylindrical section fixedly connected. The two ends of the sector ring end are respectively provided with a first connecting portion 111 and a second connecting portion 112. The first connecting portion 111 of the splicing unit 11 is used to cooperate with the second connecting portion 112 of the adjacent splicing unit 11.

[0085] Specifically, the first connecting portion 111 is an extension plate, the second connecting portion 112 is an avoidance groove, a first through hole is provided on the extension plate, and a second through hole is correspondingly provided on the avoidance groove. When installing the connecting disk 1, a plurality of splicing units 11 are sequentially spliced on the circumferential side of the rod body, and fixing bolts are installed on the extension plate and the avoidance groove, which is convenient for operation and disassembly.

[0086] In some embodiments, the connecting rod 3 is detachably connected to the first movable seat 22 and the connecting rod 3 is detachably connected to the second fixed seat 41.

[0087] One end of the connecting rod 3 is connected to the first movable seat 22 by a bolt, and the other end of the connecting rod 3 is connected to the second fixed seat 41 by a bolt. When the first movable seat 22 or the second fixed seat 41 is damaged or deformed, the first movable seat 22 or the second fixed seat 41 can be separately disassembled, which is convenient for maintenance and reduces the maintenance cost.

[0088] It should be noted that click angle sensors are both matched and provided on the first drive motor 61 and the second drive motor 71. The motor angle sensors matched and provided on these two drive motors can monitor the rotation angle of the motor in real time and accurately. During the operation of the motor, it will rotate according to the instructions issued by the control unit. The angle sensor will continuously collect the actual angle data of the motor rotation and feedback these data to the control unit.

[0089] The angle sensor can not only provide the angle information of the motor rotation, but also reflect the operating state of the motor. For example, by analyzing the rate of change of the angle, it can be judged whether the motor is operating normally. If the rotation angle of the motor changes abnormally, such as being too fast, too slow or getting stuck, the angle sensor can detect these situations in time and transmit the relevant information to the control unit so that the control unit can make corresponding processing.

[0090] In some embodiments, the second adjusting part 202 includes a fixing frame body 10, a photovoltaic support assembly 20 and a driving assembly 30. The photovoltaic support assembly 20 includes a support member 201, a first connecting member 202 and a second connecting member 203. The first end of the support member 201 is connected to the fixing frame body 10 and is rotatable about a first axial direction. The support member 201 is used for installing a photovoltaic panel. The first end of the first connecting member 202 is connected to the support member 201 and is rotatable about a second axial direction. The first end of the second connecting member 203 is connected to the second end of the first connecting member 202 and is rotatable about a third axial direction. The second end of the second connecting member 203 is connected to the fixing frame body 10 and is rotatable about a fourth axial direction. The second axial direction, the first axial direction and the fourth axial direction are sequentially arranged at intervals in the extending direction of the support member 201, and the first connecting member 202 and the second connecting member 203 are located below the support member 201 in the height direction of the fixing frame body 10, wherein the first axial direction, the second axial direction, the third axial direction and the fourth axial direction are all orthogonal to the height direction of the fixing frame body 10.

[0091] The driving assembly 30 includes a driving member 301 and a driving connecting member 302. The driving member 301 is connected to the fixing frame body 10. The first end of the driving connecting member 302 is rotatably connected to the driving member 301 so that the driving member 301 drives the driving connecting member 302 to move along the height direction of the fixing frame body 10. The first end of the driving connecting member 302 is spaced apart from the fourth axial direction in the length direction of the fixing frame body 10, and the first end of the driving connecting member 302 is located on the side of the fourth axial direction away from the first axial direction. The second end of the driving member 301 is rotatably connected to at least one of the first connecting member 202 and the second connecting member 203.

[0092] Specifically, as Figure 1 、 Figures 8 - 11 shown, the fixing frame body 10 serves as the basic support structure of the entire second adjusting part 202 and provides space for the installation of other components. In addition, various fitting parts can be arranged on the fixing frame body 10 so as to be able to be fitted and installed on different devices. For example, a ring fastener is used to enable the fixing frame body 10 to be installed on a street lamp columnar device; or a base 23 is arranged at the bottom of the fixing frame body 10 so as to be directly fixed on the ground, etc.

[0093] The first end of the support member 201 can be connected to the fixing frame body 10 through a rotating shaft 43 so that the support member 201 can rotate relative to the fixing frame body 10 about the axial direction of the rotating shaft 43, and the circumferential direction of the rotating shaft 43 coincides with the first axial direction. The upper surface of the support member 201 is used for laying a photovoltaic panel. Among them, the support member 201 can be formed by splicing a plurality of rod bodies, such as Figure 1 、 Figures 8 - 11As shown in the figure, multiple rod bodies are connected in sequence to form a "well" shape, so as to provide a larger installation space for the photovoltaic panel, and can also reduce the weight of the overall structure, facilitating subsequent rotation control. Preferably, the cross-section of the rod body is "T" shaped, and the vertical bar portion of the rod body can be connected to the fixed frame body 10. Then, when the support member 201 rotates to the horizontal position, the horizontal bar portion of the rod body can abut against the fixed frame body 10 to prevent the rotation angle of the support member 201 from being too large, thereby ensuring the safe operation of the photovoltaic support assembly 20.

[0094] In addition, it should be noted that the first end of the first connecting member 202 is connected to the support member 201, the second end of the first connecting member 202 is connected to the first end of the second connecting member 203, and the second end of the second connecting member 203 is connected to the fixed frame body 10 through a rotating shaft 43. The axial direction of the corresponding rotating shaft 43 coincides with the corresponding rotating axial direction of itself.

[0095] The driving assembly 30 includes a driving member 301 and a driving connecting member 302. The driving member 301 is connected to the fixed frame body 10, and the first end of the driving connecting member 302 is rotatably connected to the driving member 301, so that the driving member 301 drives the driving connecting member 302 to move along the height direction of the fixed frame body 10. The first end of the driving connecting member 302 is spaced apart from the fourth axial direction in the length direction of the fixed frame body 10 (such as Figure 8 the left and right directions in the figure), and the first end of the driving connecting member 302 is located on the side of the fourth axial direction away from the first axial direction. The second end of the driving member 301 is rotatably connected to at least one of the first connecting member 202 and the second connecting member 203. The driving member 301 includes a device with a linear reciprocating function, such as a cylinder, an oil cylinder, a linear module, and a shape memory alloy.

[0096] It can be understood that the driving member 301 can be fixedly installed on the fixed frame body 10 through bolts or the like to provide power for the rotation of the support frame. The driving connecting member 302 can be connected to the first connecting member 202 through the rotating shaft 43; or the driving connecting member 302 can be connected to the second connecting member 203 through the rotating shaft 43; or, preferably, the driving connecting member 302, the first connecting member 202, and the second connecting member 203 are connected through a rotating shaft 43. When the driving member 301 drives the driving connecting member 302 to move in the up and down direction, the driving connecting member 302 drives the first connecting member 202 and the second connecting member 203 to move, so that the support member 201 rotates around the first axial direction.

[0097] That is to say, the fixed frame body 10, the support frame, the first connecting member 202, and the second connecting member 203 form a four-bar linkage structure, making the overall structure simple and having high stiffness. And the hinge points of the driving connecting member 302 with at least one of the first connecting member 202 and the second connecting member 203 jointly form a spatial three-revolute joint structure to ensure that the power input is evenly transmitted to the four-bar linkage structure in the middle.

[0098] Optionally, the connection relationship between the driving connecting member 302 and the driving member 301 and the connection relationship between the driving connecting member 302 and the photovoltaic support assembly 20 can adopt ball hinge connection or pin hinge connection.

[0099] Optionally, there are multiple photovoltaic support assemblies 20, and the multiple photovoltaic support assemblies 20 are oppositely arranged on both sides of the fixed frame body 10 along the length direction of the fixed frame body 10. As Figures 8 - 11 shown, there are two photovoltaic support assemblies 20, and the two photovoltaic support assemblies 20 are symmetrically arranged on the left and right sides of the fixed frame body 10 in the left - right direction of the fixed frame body 10. That is to say, the green intelligent lighting system for intelligent mines in the embodiments of the present invention adopts a left - right symmetrical arrangement to ensure consistent power output and angle output on both sides of the driving member 301, so as to ensure that the photovoltaic panels can be unfolded and folded synchronously.

[0100] In some embodiments, there are multiple first connecting members 202, and the multiple first connecting members 202 are arranged at intervals along the width direction of the fixed frame body 10 (such as Figure 8 the front - rear direction in [[ ]]), there are multiple second connecting members 203, and the multiple second connecting members 203 correspond to the multiple first connecting members 202 one by one.

[0101] It can be understood that, as Figures 8 - 11 shown, the multiple first connecting members 202 are arranged at intervals along the front - rear direction, and the multiple second connecting members 203 are arranged corresponding to the multiple first connecting members 202 one by one to form a front - rear symmetric three - dimensional space frame, making the overall stability higher and the load - bearing capacity stronger.

[0102] In some embodiments, the photovoltaic support assembly 20 further includes a rotating member 204. The second end of the first connecting member 202 and the first end of the second connecting member 203 are both rotatably connected to the rotating member 204. The axis of the rotating member 204 coincides with the third axis, and the second end of the driving connecting member 302 is rotatably connected to the rotating member 204.

[0103] It can be understood that, as Figures 8 - 11 shown, the rotating member 204 extends along the front - rear direction. The front and rear ends of the rotating member 204 are respectively connected to two first connecting members 202 and two second connecting members 203. That is, the first connecting members 202 and the second connecting members 203 corresponding in the left - right direction are jointly hinged on the rotating member 204, and the lower end of the driving connecting member 302 is hinged to the rotating member 204.

[0104] Thus, the three-revolute joint structure among the driving connecting member 302, the first connecting member 202, and the second connecting member 203 ensures the synchronous movement among multiple connecting members. When the driving connecting member 302 moves under the action of the driving member 301, taking the rotating member 204 as the connection hub, it can drive the first connecting member 202 and the second connecting member 203 to move at the same rhythm and amplitude simultaneously. This synchronous movement is transmitted to the front and rear parallel four-bar mechanisms, enabling each four-bar mechanism to act simultaneously and coordinately, and realizing the smooth and consistent unfolding and folding process of the photovoltaic panel.

[0105] In some embodiments, the driving member 301 includes a driving part 3011 and a moving part 3012. The driving part 3011 is movable along the height direction of the fixed frame body 10, and the moving part 3012 is connected between the moving part 3012 and the first end of the second connecting member 203.

[0106] It can be understood that the driving part 3011 cooperates with the fixed frame body 10, and the driving part 3011 has the ability to move along the up and down directions. The moving ability of the driving part 3011 is the power source basis for the entire driving process, and it generates a driving effect by changing the position in the up and down directions.

[0107] In some embodiments, the driving member 301 further includes a fixed top plate 303 and a fixed shaft 304. The first end of the fixed shaft 304 is connected to the fixed top plate 303, and the extending direction of the fixed shaft 304 is consistent with the extending direction of the fixed frame body 10. In the height direction of the fixed frame body 10, the fixed top plate 303 is located above the driving part 3011, the driving part 3011 is located between the moving part 3012 and the fixed top plate 303, the moving part 3012 is sleeved on the fixed shaft 304, and the moving part 3012 is movable relative to the fixed shaft 304 along the extending direction of the fixed shaft 304.

[0108] Specifically, as Figures 8 - 11 shown, the fixed top plate 303 can be fixedly connected to the fixed frame body 10 through connecting components such as bolts, and the fixed top plate 303 is located above the fixed frame body 10. The upper end of the fixed shaft 304 is connected to the fixed top plate 303. The moving part 3012 can be sleeved on the fixed shaft 304, and the moving part 3012 can move on the fixed shaft 304 under the driving action of the driving part 3011, thereby driving the driving connecting member 302 to move.

[0109] It can be understood that the settings of the fixed top plate 303 and the fixed shaft 304 provide stable support and guidance for the driving part 3011 and the moving part 3012. During the movement of the moving part 3012, the fixed shaft 304 can restrict the movement trajectory of the moving part 3012, prevent it from shaking or deviating, and ensure the stability of the device during operation. When the driving part 3011 works, the generated force will be transmitted to the driving connecting part 302 connected thereto through the moving part 3012. This structural design can evenly disperse the force throughout the driving part 301 structure, avoid excessive local stress leading to component damage, and improve the reliability and service life of the device.

[0110] Preferably, there are multiple driving parts 3011, and the multiple driving parts 3011 are arranged at intervals along the circumferential direction of the fixed shaft 304. Preferably, the driving part 3011 is a shape memory alloy spring. That is to say, the multiple driving parts 3011 adopt a four-group spring parallel connection method, and the spring expansion and contraction are directly controlled by voltage and current, so that the parallel spring mechanism jointly realizes the movement and power output of axial sliding along the fixed shaft 304. In addition, the multiple driving parts 3011 are evenly arranged at intervals in the axial direction of the fixed shaft 304, making the driving arrangement uniform and reasonable, generating a large energy density, having a simple overall structure, and also reducing the complexity of motion control.

[0111] In some embodiments, the driving part 301 further includes a limiting part 305, and the limiting part 305 is connected to the second end of the fixed shaft 304. In a plane orthogonal to the height direction of the fixed frame 10, the cross-sectional area of the limiting part 305 is larger than the cross-sectional area of the fixed shaft 304.

[0112] Specifically, as Figures 8 - 11 shown, the limiting part 305 is arranged at the lower end of the fixed shaft 304, and the cross-sectional area of the limiting part 305 is larger than the cross-sectional area of the fixed shaft 304, so that during the movement, the limiting part 305 can play a blocking role to prevent the moving part 3012 from disengaging from the end of the fixed shaft 304 due to unexpected situations (such as abnormal driving, external force impact, etc.). Once the moving part 3012 disengages from the fixed shaft 304, the entire driving system will lose its normal transmission function, which may cause the photovoltaic panel unfolding and folding device to malfunction and even cause component damage. The setting of the limiting part 305 effectively avoids the occurrence of this situation and ensures the operation safety of the device.

[0113] It can be understood that the movement range of the moving part 3012 can be clearly defined through the limiting part 305, that is, when designing the device, the position and size of the limiting part 305 can be reasonably set according to the required stroke for the unfolding and folding of the photovoltaic panel, so that the moving part 3012 can only move within the specified range. This can avoid the moving part 3012 from moving excessively and causing collision or damage to other components, and improve the reliability and stability of the device.

[0114] In some embodiments, the driving member 301 further includes an elastic member 306. The elastic member 306 is sleeved on the fixed shaft 304, and in the height direction of the fixed frame 10, the elastic member 306 is located between the limiting portion 305 and the moving portion 3012.

[0115] It can be understood that when the moving portion 3012 moves on the fixed shaft 304 and approaches the limiting portion 305, the elastic member 306 can play a buffering role. During the normal driving process, when the moving portion 3012 reaches the end of the stroke and contacts the limiting portion 305, a certain impact force will be generated. Without the elastic member 306, this impact force may cause damage to the limiting portion 305, the moving portion 3012, and the fixed shaft 304. When the elastic member 306 is squeezed, it will undergo elastic deformation, absorb and disperse this part of the impact force, thereby reducing the damage to each component and extending the service life of the device.

[0116] Optionally, the elastic member 306 can be made of soft materials such as rubber and polyurethane materials. Of course, it can also be made of steel materials such as carbon springs and alloy springs.

[0117] In some embodiments, the cleaning unit further includes a high-pressure flushing storage tank, which is connected to both the cleaning portion 401 and the dust removal portion 402 to provide high-pressure liquid for the cleaning portion 401 and the dust removal portion 402.

[0118] It can be understood that due to the harsh mining environment, dirt and impurities such as sand, dust, and mine dust are likely to accumulate on the surface of the photovoltaic panel. These dirt will block sunlight, reduce the absorption efficiency of the photovoltaic panel for sunlight, and thus affect the power generation effect. The cleaning portion 401 of the flushing assembly can regularly spray cleaning liquid towards the photovoltaic panel, effectively removing these dirt and impurities, keeping the surface of the photovoltaic panel clean, allowing more sunlight to shine on the photovoltaic panel, improving the photoelectric conversion efficiency, and thereby increasing the power generation. The dust removal portion 402 includes a plurality of dust removal nozzles, and the plurality of dust removal nozzles can spray mist-like dust removal liquid towards the circumference of the lighting unit 100 to reduce the dust on the circumference of the lighting unit 100 and reduce the dust accumulation on the photovoltaic panel, ensuring the power generation effect of the photovoltaic portion 5.

[0119] The following describes the green intelligent lighting control method for a smart mine according to an embodiment of the present invention.

[0120] The green intelligent lighting control method for a smart mine according to an embodiment of the present invention is completed based on the green intelligent lighting system according to any one of the above embodiments, and is characterized by including the following steps:

[0121] The light intensity and the solar incident angle are detected in real time, and the target attitude of the photovoltaic part is calculated based on the light intensity and the solar incident angle, where the target attitude satisfies that the plane where the photovoltaic part is located is orthogonal to the solar light direction. It can be understood that the light detection component in the first control component is used to detect the light intensity and the solar incident angle in real time. The light detection component usually consists of a light sensor and an angle sensor. The light sensor is responsible for sensing the light intensity and converting it into an electrical signal, and the angle sensor calculates the solar incident angle using optical or mechanical principles. After receiving these data, the control unit calculates the target attitude that can make the plane where the photovoltaic part is located orthogonal to the solar light direction according to the optical principle and the preset algorithm. This calculation process comprehensively considers factors such as the position, time, and season of the sun to ensure the accuracy of the calculation result.

[0122] It provides an accurate target for subsequent adjustment of the angle of the photovoltaic part. Through real-time detection and calculation, the system can timely adjust the attitude of the photovoltaic part according to the dynamic change of the sun's position, so that the photovoltaic part always faces the direction of maximum light reception, thereby improving the light energy conversion efficiency and increasing the power generation output.

[0123] According to the target attitude, the first adjustment part and the second adjustment part are controlled to act cooperatively to adjust the spatial angle of the photovoltaic part, so that the dynamic angle (such as Figure 13 β shown in) between the normal line of the photovoltaic part and the solar rays deviates less than or equal to 1°.

[0124] It can be understood that the control unit sends control instructions to the first adjustment part and the second adjustment part according to the calculated target attitude. The first adjustment part rotates circumferentially around the lighting frame to adjust the position of the photovoltaic part in the horizontal direction; the second adjustment part adjusts the tilt angle of the photovoltaic part to change its attitude in the vertical direction.

[0125] The two adjustment parts work together to accurately adjust the spatial angle of the photovoltaic part, so that the dynamic angle deviation between the normal line of the photovoltaic part and the solar rays is less than or equal to 1°. The accurate tracking of the sun's position by the photovoltaic part is realized. Through the cooperative action of the first adjustment part and the second adjustment part, the photovoltaic part can dynamically adapt to the change of the sun's position in the horizontal and vertical directions, receive sunlight to the greatest extent, and significantly improve the light absorption rate and power generation efficiency.

[0126] When the light intensity is lower than the preset threshold or a folding instruction is received, the second adjustment part is controlled to drive the photovoltaic part to switch from the unfolded state to the folded state, so that the extending direction of the photovoltaic part is parallel to the extending direction of the first adjustment part, and the horizontal rotation freedom degree of the first adjustment part is locked.

[0127] It is understandable that the control unit monitors the light intensity in real time. When the light intensity is lower than the preset threshold (for example, at night or under bad weather conditions), or when a folding instruction is received (such as maintenance requirements, extreme weather warnings, etc.), the control unit controls the second adjusting part to drive the photovoltaic part to switch from the unfolded state to the folded state.

[0128] Meanwhile, the horizontal rotation degree of freedom of the first adjusting part is locked, so that the extending direction of the photovoltaic part is parallel to the extending direction of the first adjusting part, in order to reduce the windward area of the photovoltaic part and the influence of external environmental factors, thereby protecting the photovoltaic part from damage in bad environments. In the case of insufficient light or the need for special protection, folding up the photovoltaic part and locking the first adjusting part can reduce the risk of damage to the photovoltaic part caused by bad weather such as strong winds, heavy rains, and sandstorms, extend the service life of the photovoltaic part, and improve the reliability and stability of the system.

[0129] The actual tilt angle of the photovoltaic part is monitored in real time through the angle detection part, and the actual tilt angle is compared with the expected angle of the target posture to generate an error signal and feedback it to the first driving component and the second driving component, so as to dynamically correct the azimuth angle and pitch angle of the photovoltaic part.

[0130] It is understandable that the angle detection part in the second control component monitors the actual tilt angle of the photovoltaic part in real time and feeds the data back to the control unit. The control unit compares the actual tilt angle with the expected angle of the target posture, calculates the error between the two. An error signal is generated according to the error and fed back to the first driving component and the second driving component.

[0131] The first driving component and the second driving component dynamically correct the azimuth angle and pitch angle of the photovoltaic part according to the error signal, so that the actual posture of the photovoltaic part approaches the target posture. A closed-loop control system is formed, improving the accuracy and stability of the angle adjustment of the photovoltaic part. Through real-time monitoring and dynamic correction, the angle deviation caused by external interference, mechanical error and other factors can be corrected in time, ensuring that the photovoltaic part always maintains the best light receiving angle and further improving the power generation efficiency.

[0132] According to the real-time power generation efficiency of the photovoltaic part and the energy consumption data of the lighting unit, the tracking accuracy priority of the photovoltaic part and the brightness of the lighting part are dynamically adjusted, so as to give priority to ensuring the lighting demand when the light is insufficient and maximize the photovoltaic energy storage efficiency when the light is sufficient.

[0133] It is understandable that the control unit monitors the power generation efficiency of the photovoltaic part and the energy consumption data of the lighting unit in real time. According to these data, the tracking accuracy priority of the photovoltaic part and the brightness of the lighting part are dynamically adjusted.

[0134] When the light is insufficient, the lighting demand is preferentially guaranteed, and the tracking accuracy of the photovoltaic part is appropriately reduced to ensure that the lighting unit has sufficient power supply; when the light is sufficient, the priority of the tracking accuracy of the photovoltaic part is increased to maximize the photovoltaic energy storage efficiency, and the excess electric energy is stored. Thus, the reasonable distribution and efficient utilization of energy are realized. By dynamically adjusting according to the actual power generation and energy consumption conditions, the system can balance the lighting demand and photovoltaic energy storage under different lighting conditions, improve the energy utilization efficiency of the entire green intelligent lighting system for intelligent mines, reduce energy waste, and at the same time meet the actual production and lighting needs of the mines.

[0135] In some embodiments, the green intelligent lighting control method for intelligent mines according to the embodiments of the present invention further includes the following steps: The feedback closed-loop control uses the PID algorithm to dynamically adjust the rotation speed and steering of the first driving motor and the second driving motor according to the error signal until the deviation between the actual tilt angle and the desired angle approaches zero.

[0136] It can be understood that the PID algorithm can comprehensively consider the current error, the accumulation of errors, and the change rate of errors to precisely control the motor. By continuously adjusting the rotation speed and steering of the motor, the system can control the deviation between the actual tilt angle and the desired angle within a very small range and approach zero. This enables the photovoltaic part to reach the target attitude more precisely, further improving the perpendicularity between the photovoltaic part and the sun's rays, thereby increasing the light absorption rate and power generation efficiency. Ensure that there will be no accumulation of angle deviation during the long-term operation of the system. The differential link can suppress the oscillation of the system and avoid over-adjustment or instability of the motor during the adjustment process. Therefore, the feedback closed-loop control using the PID algorithm can enable the system to maintain a stable operating state under the influence of various interference factors (such as external wind force, mechanical transmission error, etc.), ensuring that the photovoltaic part is always in the best light receiving angle.
