Description

Technical Field

[0001] This invention belongs to the field of clean energy utilization technology in smart mines, specifically relating to a ground-mounted photovoltaic panel unfolding device for smart mines. Background Technology

[0002] With the accelerated development of smart mines, the efficient utilization of clean energy has become a core issue in the green transformation of mines. Photovoltaic power generation, as an important form of zero-carbon energy, has broad application prospects in mine surface settings. However, the complex terrain conditions (such as undulating slopes and confined spaces) and harsh environments (wind, sand, rain, snow, and mine dust) of mines pose severe challenges to the deployment of traditional fixed photovoltaic panels. On the one hand, rigidly installed photovoltaic panels are difficult to adapt to different installation scenarios, resulting in poor stability of the supporting structure; on the other hand, they are easily damaged by strong winds when deployed over large areas, lacking sufficient resilience; furthermore, traditional structures lack flexibility and are difficult to self-clean, leading to low efficiency and lifespan. 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 ground-mounted photovoltaic panel unfolding device for smart mines, which has the advantages of high structural strength, wide applicability, and high application efficiency.

[0005] The smart mine ground photovoltaic panel unfolding device according to an embodiment of the present invention includes: Fixed frame; A photovoltaic support assembly includes a support member, a first connector, and a second connector. The first end of the support member is connected to a fixed frame and is rotatable about a first axis. The support member is used to mount photovoltaic panels. The first end of the first connector is connected to the support member and is rotatable about a second axis. The first end of the second connector is connected to the second end of the first connector and is rotatable about a third axis. The second end of the second connector is connected to the fixed frame and is rotatable about a fourth axis. The second axis, the first axis, and the fourth axis are arranged sequentially at intervals along the extension direction of the support member. The first connector and the second connector are located below the support member in the height direction of the fixed frame. The first axis, the second axis, the third axis, and the fourth axis are all orthogonal to the height direction of the fixed frame. A drive assembly includes a drive member and a drive connector. The drive member is connected to the fixed frame. A first end of the drive connector is rotatably connected to the drive member so that the drive member drives the drive connector to move along the height direction of the fixed frame. The first end of the drive connector is spaced apart from the fourth axis in the length direction of the fixed frame, and the first end of the drive connector is located on the side of the fourth axis away from the first axis.

[0006] The driving component of the smart mine ground photovoltaic panel unfolding and folding device in this invention can drive the support components and photovoltaic panels to rotate, thereby realizing the unfolding and folding of the photovoltaic panels. In harsh environments such as wind, sand, rain, snow, and mine dust, the photovoltaic panels can be folded in a timely manner to reduce the accumulation of dust and snow, reduce the difficulty of self-cleaning, and improve the utilization efficiency of the photovoltaic panels. In addition, the device adopts a multi-axis rotation connection method, which makes the photovoltaic support components highly flexible. In complex mine terrain conditions (such as undulating slopes and confined spaces), the rotation angle of each connector can be adjusted to adapt the photovoltaic panels to different installation scenarios, solving the problem that traditional fixed photovoltaic panels are difficult to adapt to complex terrains and improving the stability of the overall structure.

[0007] In some embodiments, there are multiple photovoltaic support components, and the multiple photovoltaic support components are arranged opposite to each other on both sides of the fixed frame along the length direction of the fixed frame.

[0008] In some embodiments, there are multiple first connectors, which are spaced apart along the width direction of the fixed frame. There are also multiple second connectors, which correspond one-to-one with the multiple first connectors.

[0009] In some embodiments, the photovoltaic support assembly further includes a rotating member, wherein the second end of the first connector and the first end of the second connector are rotatably connected to the rotating member, the axial direction of the rotating member coincides with the third axial direction, and the second end of the drive connector is rotatably connected to the rotating member.

[0010] In some embodiments, the drive member includes a drive portion and a moving portion, the drive portion being movable along the height direction of the fixed frame, and the moving portion being connected between the drive portion and a first end of the drive connector.

[0011] In some embodiments, the drive unit further includes a fixed top plate and a fixed shaft. A first end of the fixed shaft is connected to the fixed top plate, and the extending direction of the fixed shaft is consistent with the extending direction of the fixed frame. In the height direction of the fixed frame, the fixed top plate is located above the drive unit, and the drive unit is located between the moving part and the fixed top plate. The moving part is sleeved on the fixed shaft, and the moving part is movable relative to the fixed shaft along the extending direction of the fixed shaft.

[0012] In some embodiments, there are multiple driving units, and the multiple driving units are arranged at circumferential intervals along the fixed axis.

[0013] In some embodiments, the driving member further includes a limiting part connected to the second end of the fixed shaft, wherein the cross-sectional area of ​​the limiting part is larger than the cross-sectional area of ​​the fixed shaft in a plane orthogonal to the height direction of the fixed frame.

[0014] In some embodiments, the drive member further includes an elastic member, which is fitted onto the fixed shaft and is located between the limiting portion and the moving portion in the height direction of the fixed frame.

[0023] 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.

[0024] like Figures 1-6 As shown, the smart mine ground photovoltaic panel 100 unfolding device of this invention includes: a fixed frame 1, a photovoltaic support component 2, and a drive component 3.

[0025] The photovoltaic support assembly 2 includes a support member 21, a first connector 22, and a second connector 23. The first end of the support member 21 is connected to the fixed frame 1 and is rotatable about a first axis. The support member 21 is used to mount the photovoltaic panel 100. The first end of the first connector 22 is connected to the support member 21 and is rotatable about a second axis. The first end of the second connector 23 is connected to the second end of the first connector 22 and is rotatable about a third axis. The second end of the second connector 23 is connected to the fixed frame 1 and is rotatable about a fourth axis. The second axis, the first axis, and the fourth axis are arranged sequentially at intervals along the extension direction of the support member 21, and the first connector 22 and the second connector 23 are aligned along the height direction of the fixed frame 1 (e.g., ...). Figure 1 The first axis, second axis, third axis and fourth axis are all orthogonal to the height direction of the fixed frame 1 in the vertical direction.

[0026] Specifically, such as Figures 1-6 As shown, the mounting frame 1 serves as the basic support structure for the entire photovoltaic panel 100 unfolding device, providing space for the installation of other components. Furthermore, the mounting frame 1 can be equipped with various fittings to allow for installation on different devices. For example, using ring fasteners, the mounting frame 1 can be installed on street light pole-shaped devices; or a base can be provided at the bottom of the mounting frame 1 for direct fixation to the ground.

[0027] The first end of the support member 21 can be connected to the fixed frame 1 via a pivot shaft, allowing the support member 21 to rotate relative to the fixed frame 1 about the axial direction of the pivot shaft, the circumferential direction of which coincides with the first axial direction. The upper surface of the support member 21 is used to lay the photovoltaic panel 100. The support member 21 can be composed of multiple rods joined together, such as... Figure 1 , Figure 3 and Figure 4 As shown, multiple poles are connected sequentially in a grid shape to provide more installation space for the photovoltaic panel 100, reduce the overall weight of the structure, and facilitate subsequent rotation control. Preferably, the cross-section of the pole is T-shaped, and the vertical part of the pole can be connected to the fixed frame 1. When the support member 21 rotates to the horizontal position, the horizontal part of the pole can abut against the fixed frame 1 to prevent the rotation angle of the support member 21 from being too large, thereby ensuring the safe operation of the photovoltaic support assembly 2.

[0028] In addition, it should be noted that the first end of the first connector 22 is connected to the support 21, the second end of the first connector 22 is connected to the first end of the second connector 23, and the second end of the second connector 23 is connected to the fixed frame 1 through a rotating shaft. Therefore, the axial direction of the corresponding rotating shaft coincides with its own corresponding rotation axis.

[0029] Drive assembly 3 includes a drive member 31 and a drive connector 32. The drive member 31 is connected to the fixed frame 1. The first end of the drive connector 32 is rotatably connected to the drive member 31 so that the drive member 31 drives the drive connector 32 to move along the height direction of the fixed frame 1. The first end of the drive connector 32 is aligned with the fourth axis along the length direction of the fixed frame 1 (e.g., ...). Figure 1 The drive members 31 are spaced apart in the left-right direction, and the first end of the drive connector 32 is located on the side away from the first axis in the fourth axis. The second end of the drive member 31 is rotatably connected to at least one of the first connector 22 and the second connector 23. The drive member 31 includes a device with linear reciprocating function, such as a cylinder, a hydraulic cylinder, a linear module, or a device with shape memory alloy.

[0030] Understandably, the drive component 31 can be fixedly mounted on the fixed frame 1 using bolts or the like to provide power for the rotation of the support frame. The drive connector 32 can be connected to the first connector 22 via a rotating shaft; or the drive connector 32 can be connected to the second connector 23 via a rotating shaft; or, preferably, the drive connector 32, the first connector 22, and the second connector 23 are connected via a single rotating shaft. This ensures that when the drive component 31 drives the drive connector 32 to move vertically, the drive connector 32 drives the first connector 22 and the second connector 23 to move, thereby causing the support component 21 to rotate around the first axis.

[0031] In other words, the fixed frame 1, the support frame, the first connector 22 and the second connector 23 form a four-bar linkage structure, which makes the overall structure simple and has high rigidity. Furthermore, the drive connector 32 and the hinge point of at least one of the first connector 22 and the second connector 23 together form a spatial triple hinge structure, which ensures that the power input is evenly transmitted to the four-bar linkage structure through the middle.

[0032] Optionally, the connection between the drive connector 32 and the drive component 31, and the connection between the drive connector 32 and the photovoltaic support component 2, can be a ball joint connection or a pin joint connection.

[0033] Therefore, the drive component 3 of the smart mine ground photovoltaic panel 100 unfolding and folding device of this embodiment can drive the support component 21 and the photovoltaic panel 100 to rotate, thereby realizing the unfolding and folding of the photovoltaic panel 100. In harsh environments such as wind, sand, rain, snow, and mine dust, the photovoltaic panel 100 can be folded up in a timely manner to reduce the accumulation of dust, snow, etc., reduce the difficulty of self-cleaning, and improve the utilization efficiency of the photovoltaic panel 100. In addition, the multi-axis rotation connection method of this device makes the photovoltaic support component 2 highly flexible. Under the complex terrain conditions of the mine (such as undulating slopes and confined spaces), the photovoltaic panel 100 can be adapted to different installation scenarios by adjusting the rotation angle of each connecting component, solving the problem that traditional fixed photovoltaic panels 100 are difficult to adapt to complex terrain and improving the stability of the overall structure.

[0034] Optionally, there are multiple photovoltaic support modules 2, which are arranged opposite to each other on both sides of the fixed frame 1 along the length of the fixed frame 1. Figures 1-4 As shown, there are two photovoltaic support components 2, which are symmetrically arranged on the left and right sides of the fixed frame 1 in the left-right direction. That is to say, the smart mine ground photovoltaic panel 100 unfolding and folding device of this embodiment adopts a left-right symmetrical arrangement to ensure that the power output and angle output of the drive component 31 to both sides are consistent, thereby ensuring that the photovoltaic panel 100 can unfold and fold synchronously.

[0035] In some embodiments, there are multiple first connectors 22, and the multiple first connectors 22 are arranged along the width direction of the fixing frame 1 (e.g., Figure 1 The first connectors 22 are arranged at intervals in the front and back directions. There are multiple second connectors 23, and each of the multiple second connectors 23 corresponds to one of the multiple first connectors 22.

[0036] It is understandable that, such as Figure 1 and Figure 3 As shown, multiple first connectors 22 are arranged at intervals along the front-back direction, and multiple second connectors 23 are arranged one-to-one with the multiple first connectors 22 to form a front-back symmetrical spatial three-dimensional frame, which makes the overall stability higher and the load-bearing capacity stronger.

[0037] In some embodiments, the photovoltaic support assembly 2 further includes a rotating member 24, the second end of the first connector 22 and the first end of the second connector 23 are rotatably connected to the rotating member 24, the axial direction of the rotating member 24 coincides with the third axial direction, and the second end of the driving connector 32 is rotatably connected to the rotating member 24.

[0038] It is understandable that, such as Figure 1 , Figure 3 and Figure 4 As shown, the rotating member 24 extends in the front-to-back direction. The front and rear ends of the rotating member 24 are connected to two first connecting members 22 and two second connecting members 23 respectively. That is, the first connecting members 22 and the second connecting members 23 corresponding in the left-to-right direction are hinged together on the rotating member 24, and the lower end of the driving connecting member 32 is hinged to the rotating member 24.

[0039] Therefore, the triple-hinged structure between the drive connector 32, the first connector 22, and the second connector 23 ensures the synchronicity of movement among the multiple connectors. When the drive connector 32 moves under the action of the drive member 31, the rotating member 24 serves as a connecting hub, simultaneously driving the first connector 22 and the second connector 23 to move at the same rhythm and amplitude. This synchronized movement is transmitted to the parallel four-bar linkages, enabling each four-bar linkage to operate simultaneously and in a coordinated manner, achieving a smooth and consistent unfolding and folding process for the photovoltaic panel 100.

[0040] In some embodiments, the drive member 31 includes a drive part 311 and a moving part 312. The drive part 311 is movable along the height direction of the fixed frame 1, and the moving part 312 is connected between the drive part 311 and the first end of the drive connector 32.

[0041] Understandably, the drive unit 311 cooperates with the fixed frame 1, and the drive unit 311 has the ability to move in the vertical direction. The mobility of the drive unit 311 is the power source basis for the entire driving process, and the driving action is generated by changing its position in the vertical direction.

[0042] In some embodiments, the drive member 31 further includes a fixed top plate 33 and a fixed shaft 34. The first end of the fixed shaft 34 is connected to the fixed top plate 33, and the extension direction of the fixed shaft 34 is consistent with the extension direction of the fixed frame 1. In the height direction of the fixed frame 1, the fixed top plate 33 is located above the drive part 311. The drive part 311 is located between the moving part 312 and the fixed top plate 33. The moving part 312 is sleeved on the fixed shaft 34, and the moving part 312 is movable relative to the fixed shaft 34 along the extension direction of the fixed shaft 34.

[0043] Specifically, such as Figures 3-6As shown, the fixed top plate 33 can be fixedly connected to the fixed frame 1 by bolts or other connecting components, and the fixed top plate 33 is located above the fixed frame 1. The upper end of the fixed shaft 34 is connected to the fixed top plate 33, and the moving part 312 can be fitted onto the fixed shaft 34. The moving part 312 can move on the fixed shaft 34 under the driving action of the driving part 311, thereby driving the driving connector 32 to move.

[0044] Understandably, the fixed top plate 33 and fixed shaft 34 provide stable support and guidance for the drive unit 311 and the moving unit 312. During the movement of the moving unit 312, the fixed shaft 34 can constrain the movement trajectory of the moving unit 312, preventing it from shaking or deviating, thus ensuring the stability of the device during operation. When the drive unit 311 is working, the force generated is transmitted to the drive connector 32 connected to it through the moving unit 312. This structural design can evenly distribute the force throughout the entire drive unit 31 structure, avoiding excessive local stress that could lead to component damage, and improving the reliability and service life of the device.

[0045] Preferably, there are multiple drive units 311, which are arranged circumferentially around the fixed shaft 34. Preferably, the drive units 311 are shape memory alloy springs. That is, the multiple drive units 311 employ a four-spring parallel connection, and the spring extension and contraction are directly controlled by voltage and current, thereby enabling the parallel spring mechanism to jointly achieve axial sliding motion and power output along the fixed shaft 34. Furthermore, the uniformly spaced drive units 311 along the fixed shaft 34 result in a uniform and rational drive arrangement, high energy density, simple overall structure, and reduced motion control complexity.

[0046] In some embodiments, the drive member 31 further includes a limiting part 35, which is connected to the second end of the fixed shaft 34. In a plane orthogonal to the height direction of the fixed frame 1, the cross-sectional area of ​​the limiting part 35 is greater than the cross-sectional area of ​​the fixed shaft 34.

[0047] Specifically, such as Figures 3-6 As shown, the limiting part 35 is located at the lower end of the fixed shaft 34, and the cross-sectional area of ​​the limiting part 35 is larger than that of the fixed shaft 34. This allows the limiting part 35 to act as a stop during movement, preventing the moving part 312 from detaching from the end of the fixed shaft 34 due to unforeseen circumstances (such as drive malfunction or external impact). If the moving part 312 detaches from the fixed shaft 34, the entire drive system will lose its normal transmission function, potentially causing the photovoltaic panel 100 unfolding device to malfunction or even damage to components. The limiting part 35 effectively prevents this from happening, ensuring the safe operation of the device.

[0048] Understandably, the limiting part 35 clearly limits the movement range of the moving part 312. That is, when designing the device, the position and size of the limiting part 35 can be reasonably set according to the stroke required for the photovoltaic panel 100 to unfold and fold, so that the moving part 312 can only move within the specified range. This can prevent the moving part 312 from moving excessively and causing collisions or damage to other components, thus improving the reliability and stability of the device.

[0049] In some embodiments, the drive member 31 further includes an elastic member 36, which is fitted onto the fixed shaft 34 and is located between the limiting part 35 and the moving part 312 in the height direction of the fixed frame 1.

[0050] Understandably, when the moving part 312 moves along the fixed shaft 34 and approaches the limiting part 35, the elastic element 36 acts as a buffer. During normal operation, when the moving part 312 reaches the end of its stroke and contacts the limiting part 35, a certain impact force is generated. Without the elastic element 36, this impact force might damage the limiting part 35, the moving part 312, and the fixed shaft 34. The elastic element 36 undergoes elastic deformation when compressed, absorbing and dispersing this impact force, thereby reducing damage to the components and extending the service life of the device.

[0051] Optionally, the elastic element 36 can be made of soft materials, such as rubber or polyurethane, or of steel, such as carbon springs or alloy springs.

[0052] In some embodiments, the smart mine ground photovoltaic panel 100 unfolding device of the present invention further includes a rinsing component 4, which is connected to the fixed top plate 33. The rinsing component 4 includes a rinsing section 41, which is arranged toward the photovoltaic panel 100 for spraying cleaning liquid toward the photovoltaic panel 100.

[0053] Specifically, such as Figures 1-6 As shown, the rinsing section 41 is arranged in a one-to-one correspondence with the photovoltaic panel 100, that is, each photovoltaic panel 100 is equipped with at least one rinsing section 41. The rinsing assembly 4 also includes a high-pressure rinsing tank, which is connected to the rinsing section 41 to provide cleaning fluid to the rinsing section 41.

[0054] Understandably, due to the harsh mining environment, sand, dust, and other dirt and impurities easily accumulate on the surface of the photovoltaic panel 100. This dirt blocks sunlight, reducing the photovoltaic panel 100's absorption efficiency of sunlight and thus affecting power generation. The rinsing section 41 of the rinsing assembly 4 can periodically spray cleaning liquid onto the photovoltaic panel 100, effectively removing these dirt and impurities, keeping the surface of the photovoltaic panel 100 clean, allowing more sunlight to reach the photovoltaic panel 100, improving photoelectric conversion efficiency, and thus increasing power generation.
