Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic components, in particular to a photovoltaic sound barrier panel and a photovoltaic component. Background Art

[0002] With the acceleration of urbanization, noise pollution from transportation infrastructure (such as highways, railways, and viaducts) is becoming increasingly prominent. Traditional sound barriers, as the primary means of noise reduction, reduce noise transmission by reflecting or absorbing sound waves. However, their single function is limited to passive sound insulation and does not efficiently utilize urban space resources. At the same time, the global energy structure needs to be transformed urgently. Photovoltaic power generation, as a clean energy technology, is widely used in buildings and ground-based power stations. However, its application in densely populated urban areas is often limited by land shortages and insufficient installation space.

[0003] Traditional sound barriers typically utilize vertical, upright structures, installed around roads, railways, or buildings, reducing noise transmission through physical barriers and acoustic materials. This vertical layout has the advantage of adapting to the spatial limitations of linear transportation infrastructure while effectively blocking direct sound waves between the noise source and the receiving point through its height. However, this design model is incompatible with photovoltaic integrated structures. The power generation efficiency of photovoltaic modules is closely related to the installation angle, and the 90° installation angle of vertical sound barriers deviates significantly from the optimal photovoltaic angle, resulting in reduced light energy capture efficiency.

[0004] To this end, the present invention proposes photovoltaic sound barrier panels and photovoltaic modules to solve the above problems. Summary of the Invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0032] Reference Figures 1-10FIG. 1 is a first embodiment of the present invention, which provides a photovoltaic assembly with a sound barrier panel, comprising: The vertical sound barrier frame includes a noise-facing panel 110 and a noise-repelling panel 120. The edges of the noise-facing panel 110 extend in all four directions to form an extension panel 130 to expand the surface area facing the noise. A photovoltaic integrated cavity 140 is formed in the interior of the noise-facing panel 110 and the extension panel 130. In one embodiment, the noise-facing panel 110 is arranged in a multi-layer structure, which includes a micro-perforated sound-absorbing aluminum plate layer, a thin-film battery layer, a density sound-absorbing cotton layer and a nano-reflective film layer from the outside to the inside; the micro-perforated sound-absorbing aluminum plate layer is exposed on the noise-facing surface, and the side of the nano-reflective film layer facing away from the density sound-absorbing cotton layer is in contact with the photovoltaic integrated cavity 140; wherein, light passes through the micropores of the sound-absorbing aluminum plate layer to illuminate the inner thin-film battery layer to complete the photoelectric conversion, and the sound waves pass through the micropores of the sound-absorbing aluminum plate layer into the density sound-absorbing cotton layer, the density sound-absorbing cotton layer absorbs noise to achieve noise reduction, and the bottom nano-reflective film layer reflects light, which passes through the density pores of the density sound-absorbing cotton layer and is absorbed for the second time by the thin-film battery layer.

[0033] The support frame 200 is assembled on the extended plate 130 by bolts to drive the sound barrier frame to stand on a plane; wherein, the support frame 200 includes an integrated longitudinal bracket 201 and a vertical bracket 202, and the vertical bracket 202 is fixed to a place including but not limited to roads, railways or the periphery of buildings by high-strength bolts.

[0034] The photovoltaic power generation array 300 includes multiple power generation units arranged along the length of the photovoltaic integrated cavity 140. The power generation units include multiple photovoltaic panel arrays 310 that can be extended and retracted along the width of the photovoltaic integrated cavity 140, support frames 320 connected to both sides of the photovoltaic panel arrays 310, and a horizontal synchronous linkage mechanism 330 for connecting the bottom support frames 320. The upper portions of the two sets of support frames 320 are respectively rotatably connected to the noise-facing panel 110 and the noise-backward panel 120, and the lower portions of the two sets of support frames 320 are locked by the horizontal synchronous linkage mechanism 330 to synchronize their movement. The guide rail transmission mechanism 400 includes a transverse guide rail assembly and a vertical linear guide rail assembly. The vertical linear guide rail assembly is respectively connected to the noise-facing panel 110 and the noise-backing panel 120. The vertical linear guide rail assembly drives the relative movement of the noise-facing panel 110 and the noise-backing panel 120 to open or close the photovoltaic integrated cavity 140 and then expand or shrink the photovoltaic panel array 310. The two groups of support frames 320 synchronize the relative movement of the noise-facing panel 110 and the noise-backing panel 120 in opposite directions or towards each other; the transverse guide rail assembly is connected to the transverse synchronous linkage mechanism 330. The transverse guide rail assembly adjusts the rotation of multiple support frames 320 through the transverse synchronous linkage mechanism 330. The rotating multiple support frames 320 drive the photovoltaic panel array 310 to be tilted inside the photovoltaic integrated cavity 140.

[0035] like Figure 1 、 Figure 3 As shown, the back noise panel 120 includes a panel body 121. The surface of the panel body 121 is penetrated to form a plurality of windows 122 arranged at equal intervals along the length direction. A silicone rubber sealing strip 125, a light-guiding transparent plate 124 and a focusing reflective plate 123 are sequentially laid along the length direction of the window 122. The focusing reflective plate 123 is hinged to the panel body 121, and the light-guiding transparent plate 124 allows light to pass through.

[0036] In one embodiment, the surface of the panel body 121 is formed of a perforated metal plate, and the inner cavity thereof is filled with sound-absorbing material, which not only protects the internal structure but also reduces sound reflection from the back noise surface, thereby preventing sound waves from spreading to unprotected areas.

[0037] In one embodiment, the light-guiding transparent plate 124 is embedded in the panel body 121 and is bonded to the silicone rubber sealing strip 125. When the focusing reflector 123 flips upward at the hinge point to close the window, it abuts against the light-guiding transparent plate 124 to drive the light-guiding transparent plate 124 to move slightly upward. The upward-moving light-guiding transparent plate 124 squeezes the silicone rubber sealing strip 125 to deform it.

[0038] Reference Figure 10 As shown, the focusing reflector 123 includes a straight plate body 1231 and two arc-shaped protrusions 1232 arranged on the side of the straight plate body 1231 facing the noise-receiving panel 110. The two arc-shaped protrusions 1232 are laid at both ends along the width direction of the straight plate body 1231 to achieve focusing, so that more reflected light enters the photovoltaic integrated cavity 140 through the window 122.

[0039] Exemplarily, the surfaces of the focusing reflector 123 and the arc-shaped protrusion 1232 are interspersed with rough surfaces and smooth surfaces. When the focusing reflector 123 is set at an angle, when the light is incident on the focusing reflector 123, the light is reflected or scattered to pass through the window 122 and enter the photovoltaic integrated cavity 140, so that the lower part of the photovoltaic integrated cavity 140 also has strong light.

[0040] Reference Figure 1 、 Figure 2 as well as Figure 3 As shown, a photovoltaic assembly with a sound barrier panel includes a power drive assembly 500; the power drive assembly 500 includes a vertical drive assembly, which drives the photovoltaic panel array 310 to unfold synchronously by unfolding the vertical linear guide rail assembly, and synchronously drives the focusing reflector 123 to flip down to adjust the angle.

[0041] Exemplarily, the vertical linear guide rail assembly includes a fixed guide rail cylinder 421 and a linkage guide rail plate 422, which are respectively connected to the noise-facing panel 110 and the noise-back panel 120. The tail of the fixed guide rail cylinder 421 is equipped with a limited length block 4211, and the tails of the two linkage guide rail plates 422 are equipped with limited short blocks 4221. The linkage guide plates 422 are engaged and run along the axial direction of the fixed guide rail cylinder 421. The limited length block 4211 and the limited short block 4221 are used to limit the relative distance and position of the linkage guide plate 422 and the fixed guide rail cylinder 421.

[0042] There are two groups of vertical drive components, which are respectively arranged at both ends of the photovoltaic integrated cavity 140. The vertical drive components include a vertical rack 525 vertically mounted on the back noise panel 120, and an embedded rack 526 moving along the length direction of the vertical rack 525, and a traction rope connected to the end of the embedded rack 526 facing the back noise panel 120. The traction rope passes through the embedded rack 526 and the back noise panel 120, connects multiple focusing reflectors 123 in series, and is connected to another embedded rack 526.

[0043] Exemplarily, the traction rope pulls the light-collecting reflector 123 to suppress its tendency to flip downward. During the flipping process of the light-collecting reflector 123 , the traction rope slides inside the reflective surface.

[0044] Exemplarily, a guide groove 527 having a length greater than that of the embedded rack 526 is defined inside the vertical rack 525 .

[0045] Reference Figure 2As shown, the vertical drive assembly also includes a servo rotary motor 522 arranged in the inner cavity of the extended expansion plate 130, a first rotary gear 523 and a second rotary gear 524 connected to the output end of the servo rotary motor 522, the first rotary gear 523 is engaged with the embedded rack 526, the second rotary gear 524 is engaged with the vertical rack 525, and the gear ratio of the first rotary gear 523 and the embedded rack 526 is twice the gear ratio of the second rotary gear 524 and the vertical rack 525, so that the moving speed of the embedded rack 526 is twice that of the vertical rack 525, so as to synchronously realize the opening of the photovoltaic integrated cavity 140 and the flipping of the focusing reflector 123.

[0046] Exemplarily, a mounting plate 521 for mounting a servo rotary motor 522 is further configured in the inner cavity of the epitaxial expansion plate 130 .

[0047] For example, when the number of triangular teeth distributed on the periphery of the first rotating gear 523 is twice the number of triangular teeth distributed on the periphery of the second rotating gear 524, the first rotating gear 523 and the second rotating gear 524 are driven by the servo rotating motor 522 to rotate synchronously. When the servo rotating motor 522 drives the second rotating gear 524 to engage with the vertical rack 525, the vertical rack 525 drives the back noise panel 120 to move toward or away from the front noise panel 110 to open or close the photovoltaic integrated cavity 140.

[0048] Synchronously, when the servo rotary motor 522 drives the second rotary gear 524 to engage with the vertical rack 525, driving the back noise panel 120 to move away from the front noise panel 110, the first rotary gear 523 is synchronously driven to engage with the embedded rack 526, driving the embedded rack 526 to move relative to the vertical rack 525, and the traction rope gradually moves toward the end of the back noise panel 120. The focusing reflector 123 is flipped downward under the action of gravity, so that the light is reflected into the photovoltaic integrated cavity 140 to enhance the light intensity inside the photovoltaic integrated cavity 140.

[0049] Reference Figure 4-Figure 6 As shown, the power drive assembly 500 also includes a transverse drive component, which includes a drive motor 512 installed in the inner cavity of the extension plate 130 away from the servo rotary motor 522, a drive gear 513 connected to the output end of the drive motor 512, and a spur rack 514 meshing with the drive gear 513. The spur rack 514 is assembled on a transverse track to drive the transverse synchronous linkage mechanism 330 to adjust its position through the transverse track.

[0050] Illustratively, a supporting horizontal plate 511 for mounting a driving motor 512 is further configured in the inner cavity of the extension plate 130 .

[0051] Exemplarily, the transverse track includes a transverse track plate 411 mounted on the bottom wall of the noise-receiving panel 110, and a built-in track plate 412 that is engaged and moves along the length direction of the transverse track plate 411. The transverse track plate 411 is laid along the length direction of the noise-receiving panel 110, and a spur rack 514 is mounted on the side of the built-in track plate 412. The driving gear 513 is engaged with the spur rack 514 to drive the spur rack 514 to move along the length direction of the noise-receiving panel 110, thereby driving the built-in track plate 412 and the spur rack 514 to move synchronously.

[0052] Reference Figure 7-Figure 9 As shown, the photovoltaic panel array 310 includes a plurality of mutually hinged central photovoltaic panels 312, and two side photovoltaic panels 311 hinged to the two side central photovoltaic panels 312. The support frame 320 is respectively connected to the two side photovoltaic panels 311. When the back noise panel 120 moves away from the front noise panel 110 through the vertical linear guide assembly, the support frame 320 synchronously stretches the photovoltaic panel array 310, so that the hinge angle of the central photovoltaic panel 312 and the side photovoltaic panels 311 is expanded from a folded state to an approximately flat state.

[0053] The support frame 320 includes an upper rotating head 321, a support column 322 and a lower rotating head 323. The upper rotating head 321 and the lower rotating head 323 are inserted into the inner cavity of the support column 322 to expand and contract in the inner cavity of the support column 322 under external force. The upper rotating head 321 is rotatably installed on the noise-facing panel 110 and the noise-back panel 120.

[0054] Exemplarily, both ends of the support column 322 are provided with movable cavities 3221 for inserting and sliding the upper rotating head 321 and the lower rotating head 323 .

[0055] Exemplarily, the upper rotating head 321 includes an extension head 3211 that is engaged in the noise-facing panel 110 or the noise-back panel 120 , a cylinder 3212 connected to the extension head 3211 , and an upper insertion rod 3213 connected to the surface of the cylinder 3212 , and the upper insertion rod 3213 is inserted into the inner cavity of the support column 322 .

[0056] Exemplarily, the lower rotating head 323 includes a round roller 3231 locked by the horizontal synchronous linkage mechanism 330 , a lower insertion rod 3232 connected to the round roller 3231 , and the lower insertion rod 3232 is inserted into the inner cavity of the support column 322 .

[0057] Reference Figure 7-Figure 9As shown, the lower rotating head 323 is connected to the horizontal synchronous linkage mechanism 330, and the horizontal synchronous linkage mechanism 330 includes a linkage middle plate 331 assembled on the built-in track plate 412, two connecting rods 332 inserted in the inner cavity of the linkage middle plate 331, and linkage side plates 333 respectively connected by the two connecting rods 332. The linkage side plates 333 are locked with the round rollers 3231 of the lower rotating head 323 by connection methods not limited to bolts or slots, thereby ensuring the synchronous displacement of the support frame 320.

[0058] Exemplarily, the two connecting rods 332 slide in the linkage middle plate 331 to drive the distance between the two linkage side plates 333 to change, so as to follow the change in the distance between the two sets of support frames 320; the two connecting rods 332 rotate in the linkage middle plate 331 to adaptively adjust the angle of the linkage side plate 333 following the angle adjustment of the support frame 320.

[0059] A photovoltaic sound barrier panel includes an upright sound barrier frame, which is applied to the above-mentioned photovoltaic assembly.

[0060] Working principle: The sound barrier frame is installed at locations not limited to roads, railways or around buildings through the supporting frame 200. The noise-facing panel 110 faces the noise source. The noise-facing panel 110 adopts a multi-layer structure of micro-perforated sound-absorbing aluminum plate layer, thin-film battery layer, density sound-absorbing cotton layer and nano-reflective film layer. Sound waves enter the density sound-absorbing cotton layer through the micropores and are absorbed. Light passes through the micropores to illuminate the thin-film battery layer to realize photoelectric conversion. The nano-reflective film layer reflects light for secondary absorption by the thin-film battery layer. At the same time, the edge of the noise-facing panel 110 extends to form an extension plate 130, which expands the surface area of ​​the noise surface to enhance the noise reduction effect, and the internal photovoltaic integrated cavity 140 can accommodate a photovoltaic power generation array 300.

[0061] The noise-receiving panel 110 is also provided with sensors for sensing light and raindrops, and an energy storage battery is installed inside. The photovoltaic power generation array 300 generates electricity through photoelectric conversion, which is stored in the energy storage battery to power the sensor, servo rotary motor 522, and drive motor 512; when there is insufficient light or the energy storage capacity is lower than the threshold, temporary power supply can be provided through the thin-film battery layer or the backup power supply.

[0062] When the sensor monitors the light intensity and light direction in real time, when it is detected that the light intensity reaches a preset threshold and the sensor feedback shows no precipitation, the servo rotation motor 522 and the drive motor 512 are powered. First, the servo rotary motor 522 is started, and the first rotary gear 523 and the second rotary gear 524 at its output end rotate synchronously. The first rotary gear 523 drives the embedded rack 526 to move along the vertical rack 525 at a faster speed, and the traction rope gradually moves toward the end of the back noise panel 120. The focusing reflector 123 is flipped downward by gravity to form a certain tilt angle. The structure of the surface with rough and smooth surfaces interlaced reflects or scatters light, and the light passes through the window 122 into the photovoltaic integrated cavity 140, thereby enhancing the light intensity in the photovoltaic integrated cavity 140. At the same time, the second rotary gear 524 drives the vertical rack 525 to drive the back noise panel 120 to move away from the front noise panel 110, opening the photovoltaic integrated cavity 140, and linking the support frames 320 on both sides to stretch the central photovoltaic panel 312 and the side photovoltaic panels 311 of the photovoltaic power generation array 300, so that they are unfolded from the folded state. The central photovoltaic panel 312 and the side photovoltaic panels 311 are almost combined into a planar plate.

[0063] Next, the lateral drive assembly responds to the angle of illumination. The drive motor 512, through the drive gear 513, engages the spur rack 514, driving the internal track plate 412 on the lateral track to move along the length of the noise-facing panel 110, thereby driving the lateral synchronous linkage mechanism 330 to adjust its position. At this point, the lower rotating head 323 of the support frame 320 moves along with the lateral synchronous linkage mechanism 330, driving the photovoltaic array 310 to move in conjunction with the lateral synchronous linkage mechanism 330. The upper rotating head 321 rotates on the noise-facing panel 110 and the noise-receiving panel 120. The drive motor 512 continues to adjust until the photovoltaic array 310 is facing the light.

[0064] During this process, the multi-layer hinged structure of the photovoltaic panel array 310 allows the angle between the adjacent central photovoltaic panels 312 and the side photovoltaic panels 311 to change dynamically. The upper rotating head 321 and the lower rotating head 323 of the support frame 320 telescope and slide in the inner cavity of the support column 322 to ensure structural stability during panel adjustment.

[0065] Without destroying the upright structure of the traditional sound barrier frame, the present application sets the photovoltaic power generation array 300 in the sound barrier frame, which not only retains its vertical installation adaptability to linear scenes such as roads and railways, but also greatly expands the layout area of ​​the photovoltaic panel array 310 through the folding and array structure of the photovoltaic power generation array 300. Compared with the traditional method of attaching to the noise-facing surface or the noise-back surface, it has more light-receiving surface area. Combined with the openable photovoltaic integrated cavity 140 and the light-guiding window 122 design of the noise-back panel 120, multi-dimensional utilization of sunlight is achieved: the openable design of the sound barrier frame introduces direct light into the cavity, and through the vertical linear guide rail The component drives the noise-facing panel 110 and the noise-back panel 120 to move relative to each other, and the opening amplitude is automatically adjusted by the servo rotary motor 522 according to the light sensor data to ensure that direct light is incident vertically on the photovoltaic panel array 310. When the noise-facing panel 110 is opened, the direct light directly illuminates the photovoltaic panel array 310; the focusing reflector 123 of the noise-back panel 120 collects the back-scattered light through the arc-shaped protrusion 1232, and reflects it to the bottom of the photovoltaic integrated cavity 140 through the light guide window 122, realizing dual-light source fill lighting, so that the photovoltaic panel array 310 can dynamically adjust its angle to receive light in the best posture, greatly improving the power generation efficiency compared with the traditional fixed vertical installation.
