Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic railings, and more specifically, to an integrated photovoltaic railing and a method for using the same. Background Art

[0002] In the prior art, a double-sided power generation photovoltaic module applied to scenarios such as building guardrails and balcony railings is called a double-sided power generation photovoltaic fence or photovoltaic railing. Such products usually adopt high-efficiency heterojunction battery technology and integrate large-size single-crystal BC technology to achieve double-sided power generation. By vertically installing the photovoltaic glass module with the railing base and columns integrated, it uses the direct sunlight on the front and the ground reflected light on the back to generate electricity, realizing the integration function of building enclosure and photovoltaic power generation. The technical core lies in embedding the photovoltaic glass into the railing structure, and taking into account the lighting requirements through the light-transmitting characteristics of the gaps between the battery chips. However, limited by the vertical installation method, the back-side power generation efficiency depends on the ground reflectivity and ambient light intensity.

[0003] However, this type of integrated photovoltaic railing is limited by the vertical installation method, and its back-side power generation efficiency is relatively dependent on the ground reflectivity and environment light. Moreover, in the scenarios of building curtain walls or open balconies with high ventilation requirements, where the ground materials generally use permeable bricks and green grasslands, the reflectivity is very low, resulting in insufficient back-side power generation gain. Although the prior art can try to alleviate the ventilation and light-transmitting problems by optimizing the light-transmitting rate of the battery gaps, it still cannot break through the fundamental contradiction of the limited light-receiving range on the back side under vertical installation.

[0004] Because although the battery gap area allows some light to penetrate, the battery chip coverage area still forms local occlusion, resulting in the fact that the actually received reflected light on the back side can only cover a limited area. In urban building complexes with large fluctuations in reflectivity, the components with a fixed angle cannot dynamically adjust the light-receiving surface, which will cause the overall power generation efficiency to fluctuate beyond the design threshold. Although increasing the height of the junction box bracket or using a high-reflectivity coating can improve the back-side gain, it sacrifices the structural stability and space utilization rate, and does not solve the coupling contradiction between ventilation and power generation efficiency.

The connection terminals of the double-sided photovoltaic panel are placed on the inner bottom of the contact-type snap-in plate and are connected to the contacts at the bottom of the contact-type snap-in plate. Contact-type snap-in bases embedded with the contact-type snap-in plate are fixedly installed on both side edges of the open end of the second U-shaped side frame.

[0013] As a further solution of the present invention: a secondary light-guiding mechanism is fixedly installed on the bottom inner side of the opening end of the second U-shaped side frame, the secondary light-guiding mechanism includes a base partition plate, an airbag bag is fixedly installed on the bottom surface of the base partition plate, a third light-guiding tube is fixedly installed on the bottom of the airbag bag, first light-guiding tubes are fixedly installed on both sides of the upper surface of the base partition plate, the first light-guiding tube and the third light-guiding tube are connected with an inner light-transmitting tough bag, a second light-guiding cavity covering the outside of the first light-guiding tube is fixedly installed on the bottom inner side of the opening end of the second U-shaped side frame, the first light-guiding cavity is fixedly installed on both sides of the second light-guiding cavity, the first light-guiding cavity is a U-shaped cavity structure, and the sides of the second light-guiding cavity and the first light-guiding cavity facing the double-sided photovoltaic panel are both oblique transparent layers.

[0014] As a further solution of the present invention: both side ends of the first light guide tube are connected to second light guide tubes in a communicating manner. The first light guide tube and the second light guide tubes at both side ends together form a U-shaped structure, and the second light guide tubes at both side ends are entirely placed inside the first light guide cavity and are close to the side of the inclined transparent layer. The inner cavities of the first light guide cavity and the second light guide cavity are in communication, and a number of air injection holes are sequentially arranged and installed on the inclined transparent layers of the first light guide cavity and the second light guide cavity.

[0015] As a further solution of the present invention: a servo air compressor is fixedly installed at a position below the third gear disc inside the junction box. Two third air supply hoses are fixedly installed at the output end of the servo air compressor. A first air supply hose that is in communication with each push-button valve head port is fixedly installed inside the sleeved area. The third air supply hose is in communication with the first air supply hose to supply air to different push-button valve head ports. The inner connecting hard tube is integrally L-shaped and penetrates into the first light guide cavity on the side of the second U-shaped side frame through the cavity disc. Second air supply hoses are connected to both sides of the airbag bag in a communicating manner. The second air supply hoses respectively penetrate into the first light guide cavities on both sides, and air guide open masks are fixedly installed at the ends that penetrate into the first light guide cavities.

[0016] A method for using an integrated photovoltaic railing includes the following steps: S1: First, the second gear disc and the third gear disc are driven to rotate synchronously by a servo motor, driving the extension rod and the threaded rod to rotate. The rotation of the threaded rod passes through the adjustment areas divided by the partition disc, causing the nut sleeves in each adjustment area to move up and down along the threaded rod, driving the second U-shaped side frame to displace within the self-adjusting border module; S2: Then, when the second U-shaped side frame moves, the first gear discs on both sides thereof engage with the side tooth plates on the inner wall of the first U-shaped side frame, forcing the second U-shaped side frame to rotate synchronously during the displacement process to control the inclination angle of the double-sided photovoltaic panel module; S3: Then, when the second U-shaped side frame is inclined to the maximum angle, the convex sealing interface presses the push-button valve head port, starting the servo air compressor to inject air flow into the first light guide cavity through the hose. The air flow blows the surface of the double-sided power generation photovoltaic panel through the air injection holes. At the same time, the airbag bag is inflated through the second air supply hose, pushing the third light guide tube to extend; S4: Finally, the extended third light guide tube conducts the ground reflected light to the first light guide tube and the second light guide tube through the inner light-transmitting flexible bag, and is secondarily reflected to the back of the double-sided power generation photovoltaic panel through the inclined transparent layer. The horizontal detector monitors the inclination state in real time and cooperates with the closed-loop adjustment of the servo motor to realize the automatic switching between the vertical protection mode and the inclined power generation mode.

[0017] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) Through the dynamic cooperative structure of the self-adjusting frame module and the flip frame mechanism, the built-in gear meshing and threaded rod transmission structure are used to achieve synchronous tilt adjustment of the bifacial photovoltaic panels, so that the components can dynamically optimize the front and back light receiving range according to the solar incident angle. Compared with the existing technology that strongly depends on the ground reflectivity, the bifacial power generation efficiency is significantly improved through the complementary mechanism of front direct light capture and back scattered light. Especially in the low-angle light at dawn and dusk, the separated tilt layout effectively avoids the shadow of adjacent panels. Combined with the light-guiding mechanism, the reflected light is secondary guided to the back battery area. In low-reflectivity scenes such as green grass, a stable power generation gain can still be maintained, solving the core contradiction of the vertical installation mode where the back light is limited.

[0018] (2) The integrated design of ventilation, heat dissipation and self-cleaning effectively resolves the coupling conflict between the structure and performance of the photovoltaic guardrail. The continuous air duct formed by the interval tilt can disperse the wind pressure while reducing the temperature rise of the components. In combination with pneumatic cleaning, the high-pressure airflow is triggered to be ejected through the light-guiding cavity at the maximum inclination angle, and the surface dust removal and snow removal are completed simultaneously. This not only avoids the power generation attenuation caused by poor ventilation of the traditional vertical structure, but also realizes the coordinated optimization of heat dissipation efficiency and light energy utilization through the integrated design of the airflow path and the light-guiding channel. It is particularly suitable for high-wind speed coastal areas and dusty and sandy environments.

[0019] It adopts independent double-sided photovoltaic panel modules and contact-type quick connection design, which supports live plug-in and maintenance of single components without affecting the overall operation. The light-guiding mechanism is driven by airbags to achieve adaptive extension, and the ground reflected light is directed to the back of the photovoltaic panel in a tilted state, so that the back power generation efficiency in low-reflectivity scenes is improved. Combined with the closed-loop control of the servo motor and the level detector, the system can autonomously switch between the vertical protection mode and the tilted power generation mode.

[0023] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for schematic purposes and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0024] The following will describe in detail an integrated photovoltaic railing and its usage method provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some technical personnel in the well-known technical fields, other alternative methods can also be used for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0025] As Figures 1 to 11 shown, an embodiment of the present invention provides an integrated photovoltaic railing, including a junction box 1. At both ends of the upper surface of the junction box 1, a bottom busbar box 2 is fixedly installed. Above the bottom busbar box 2, a self-adjusting frame module 3 is fixedly installed. The junction box 1, the bottom busbar boxes 2 on both sides, and the self-adjusting frame module 3 form a U-shaped frame structure. At the open end of the U-shaped frame structure, a plurality of independent flipping frame mechanisms 4 are sleeved through the self-adjusting frame module 3, and each flipping frame mechanism 4 is configured with an independent double-sided photovoltaic panel module 5. The self-adjusting frame module 3 includes a first U-shaped side frame 31. The flipping frame mechanism 4 includes a second U-shaped side frame 41 movably sleeved in the first U-shaped side frame 31. On both side edges of the second U-shaped side frame 41, first gear disks 44 are arranged. On the inner wall of the first U-shaped side frame 31, side tooth plates 33 meshing with the first gear disks 44 are arranged, so that when the second U-shaped side frame 41 moves up and down inside the first U-shaped side frame 31, the second U-shaped side frame 41 rotates itself due to the meshing relationship between the first gear disks 44 and the side tooth plates 33, and the second U-shaped side frame 41 is controlled to rotate synchronously to tilt the double-sided photovoltaic panel module 5. Among them, the double-sided photovoltaic panel module 5 includes a double-sided power generation photovoltaic panel 52. By moving the second U-shaped side frame 41 up and down, a plurality of double-sided power generation photovoltaic panels 52 rotate synchronously to achieve an overall vertical and dispersed inclined arrangement state.

[0026] To solve the problem that the existing vertically installed double-sided photovoltaic guardrail has limited light reception on the back due to the static structure being unable to dynamically adapt to the fluctuations in ground reflectivity and the shading of the solar cells, and the poor ventilation exacerbates the temperature rise, making it difficult to synergistically optimize the power generation efficiency and heat dissipation performance. Now, the above technical solution is adopted to solve this problem. The above technical solution mainly consists of a junction box 1, a bottom busbar box 2, a self-adjusting frame module 3, a flipping frame mechanism 4, and a double-sided photovoltaic panel module 5. The junction box 1 and the bottom busbar box 2 are cavity structures in the prior art for connecting and transferring power cables and electrical components, ensuring that the electrodes led out from the solar cells by the busbars are connected to the terminals here to form current output nodes. Generally, MC4 or similar waterproof connectors can be selected to facilitate the quick plugging and unplugging of cables on-site. The configured self-adjusting frame module 3 is a U-shaped holding frame structure with built-in linkage components. On the one hand, it is used to support several double-sided photovoltaic panel modules 5 inside, and on the other hand, it is used to control several double-sided photovoltaic panel modules 5 to rotate synchronously through the built-in linkage components, enabling the configured several double-sided photovoltaic panel modules 5 to be perpendicular to the junction box as a whole or to be tilted and spread out separately, as shown in the attached Figure 11As shown, in the installed state of operation, efficient space utilization can be achieved, especially suitable for land-sensitive sites. For example, in the prior art, it can be used as a fence, soundproof wall, or building exterior wall, combining power generation, privacy protection, and decorative functions. For example, the photovoltaic guardrail on highways can reduce noise and land occupation. In the vertical state, since the power generation on the back highly depends on the ground material, it can be switched to a servo-tilt-adjustable state. In this state, not only can the dynamic tilt be optimized, different from the strong dependence of traditional vertical photovoltaic guardrails on the ground reflectivity, but also the synergistic effect of double-sided components can be achieved. The front directly receives direct sunlight for capture, and the back expands the range of ground-reflected light reception through the tilt angle, while using scattered light to make up for it. Compared with the fixed shading strips installed vertically, the separated design reduces the shadow occlusion between the panels. By tilting adaptively at different illumination angles of the morning and evening sunlight, the occlusion contradiction of the backlight side by the cell coverage area can be effectively alleviated. In addition, through the spaced layout, a natural air duct can be formed between the panels, synchronously solving the heat dissipation and ventilation coupling contradiction of vertical installation. This can not only reduce the temperature rise of the components and avoid the wind speed attenuation caused by the closed vertical structure, but also, in terms of wind resistance, the separated layout can disperse the wind pressure, especially for use in areas with high typhoon damage along the coast, expanding the deployment scenarios of the photovoltaic system. Additionally, due to the special structure and operation of the photovoltaic guardrail, after installation, except for the necessary daily maintenance work, it is basically in an unmanned management working state. As is well known, the power generation of photovoltaic depends on the irradiated area of the photovoltaic surface, and outdoors there is not only dust but also weather interference, especially snow interference. During the working process of its tilted and separated installation, it can also have the characteristics of self-cleaning and anti-snow accumulation through tilting, also different from vertical installation, which can greatly reduce the power generation loss caused by snow accumulation. Therefore, the linkage rotation adjustment characteristics of the self-adjusting frame module 3 and the flipping frame mechanism 4 can achieve the effect of coordinated regulation of light, heat, and wind on the double-sided power generation photovoltaic panel 52, providing a more stable photovoltaic railing for high-wind-speed areas, cities with fluctuating reflectivity, and ecologically sensitive areas.

[0027] As Figures 1 to 11 As shown, a servo motor 7 is fixedly installed at one end position inside the junction box 1. The output end of the servo motor 7 faces the upper side of the junction box 1, and a second gear disk 8 is fixedly installed on the output end. A third gear disk 10 is movably installed at a position inside the junction box 1 opposite to the second gear disk 8. A crawler sleeve 9 that meshes with the second gear disk 8 is sleeved on the outer surface of the third gear disk 10. Extension rods 11 that fixedly penetrate the top of the junction box 1 are fixedly installed at the center positions of the upper surfaces of the third gear disk 10 and the second gear disk 8. The extension rods 11 extend upward and pass through the bottom busbar box 2 and into the inner bottom of the first U-shaped side frame 31.

[0028] Among them, the configured servo motor 7 is a structure capable of servo drive in the prior art. In the working state, the second gear disk 8 at its output end can be controlled to perform servo rotation. In the non-working state, the second gear disk 8 at the output end does not rotate. Through the laterally meshed crawler sleeve 9, the third gear disk 10 can be synchronously linked, so that the extension rods 11 at both driving ends can rotate synchronously.

[0029] As Figures 1 to 11 shown, the overall shape of the first U-shaped side frame 31 is U-shaped, and the open ends of the first U-shaped side frames 31 on both sides are all oriented towards the center of the junction box 1. A fitting area 32 is provided inside the open end of the first U-shaped side frame 31. A threaded rod 35 is movably installed at the axial center position of the fitting area 32. The bottom of the threaded rod 35 is fixedly connected to the extension rod 11 extending to the inner bottom of the first U-shaped side frame 31. A number of partition disks 36 are sequentially and fixedly installed on the outer surface of the threaded rod 35, and the threaded rod 35 is divided into a number of independent equal-length areas by the partition disks 36. Taking each separated equal-length area as an adjustment area, pressing valve heads 34 are fixedly installed at both ends of each adjustment area on the side wall of one side of the fitting area 32. A side tooth plate 33 is fixedly installed on the side wall of the fitting area 32 opposite to the side where the pressing valve heads 34 are configured.

[0030] Among them, the configured first U-shaped side frame 31 is overall U-shaped. The configured pressing valve head 34 is a valve head structure that can be opened by pressing in the prior art. Its outer surface is parallel to the side wall of the fitting area 32. After being pressed by the convex sealing interface 43 on the subsequent rotating cavity disk 42, it can communicate with the convex sealing interface 43 in the pressed state to form a temporary communication air passage. The configured extension rod 11 is connected to the threaded rod 35, and the rotation of the threaded rod 35 is controlled by controlling the extension rod 11. The threaded rod 35 is divided into a number of independent equal-length areas by the partition disks 36 to limit the flipping range of the flipping frame mechanism 4 in each separated area.

[0031] As Figures 1 to 11 shown, the flipping frame mechanism 4 further includes cavity disks 42 fixedly installed at the middle positions on both sides of the second U-shaped side frame 41. Each second U-shaped side frame 41 is movably sleeved on each adjustment area in the fitting area 32 through the cavity disks 42 on both sides. A first gear disk 44 is fixedly installed at the outer center position of each cavity disk 42. The side of the first gear disk 44 meshes with the side tooth plate 33 on the side wall of the fitting area 32. A nut sleeve 45 is movably installed at the outer center position of the first gear disk 44. The nut sleeve 45 is meshed and installed on the threaded rod 35 of each adjustment area.

[0032] Among them, during the rotation of the configured threaded rod 35, the nut sleeves 45 in each adjustment area can be synchronously driven up and down by the effect of the lead screw drive to control the up and down movement of the second U-shaped side frame 41 inside the bracket. During each up and down movement, in cooperation with the meshing effect of the upper side tooth plate 33 on the side, the first gear disk 44 is driven to rotate, so as to control the second U-shaped side frame 41 to rotate while moving up and down inside the bracket, achieving the subsequent self-adaptive tilting effect.

[0033] As Figures 1 to 11 shown, the flipping frame mechanism 4 further includes two convex sealing interfaces 43 fixedly installed on the outer edge of the cavity disk 42 and spaced 180 degrees apart. When the nut sleeve 45 is located in the exact middle of the adjustment area, the two convex sealing interfaces 43 are directly above and below the nut sleeve 45, and at this time, the second U-shaped side frame 41 is perpendicular to the junction box 1; a level detector 47 is fixedly installed in the inner cavity of the cavity disk 42, and two internal connecting rigid tubes 46 communicating with the two convex sealing interfaces 43 are fixedly installed on the side of the level detector 47. A reflector 14 is press-fitted and installed at the middle position on the upper surface of the junction box 1.

[0034] Among them, the configured convex sealing interface 43 and the cavity disk 42 are an integral structure and protrude outward as a whole. During rotation, it will press the push-type valve head port 34. By configuring the convex sealing interface 43 on the outer edge of the cavity disk 42 and ensuring that when the nut sleeve 45 is located in the exact middle of the adjustment area, the two convex sealing interfaces 43 are directly above and below the nut sleeve 45, and at this time, the second U-shaped side frame 41 is perpendicular to the junction box 1, it can be realized that during the actual working process, when the nut sleeve 45 is located in the exact middle of the adjustment area, the second U-shaped side frame 41 on the side of the first U-shaped side frame 31 is in a state relative to the junction box 1, and the overall structure has an arranged effect. During the clockwise and counterclockwise rotation of the threaded rod 35, the up and down movement of the nut sleeve 45 can be controlled. During the movement, under the action of the meshing of the first gear disk 44 and the side tooth plate 33, the cavity disk 42 rotates. When rotating to both ends of the adjustment area, the convex sealing interfaces 43 on both sides will approach and press down the push-type valve head port 34. Specifically, when the double-sided photovoltaic panel module 5 is tilted to the maximum angle, the push-type valve head port 34 will be connected, and the air duct will inject into the first light guide cavity 48 and the second light guide cavity 49 through the cavity disk 42, and the first light guide cavity 48 and the second light guide cavity 49 will be used to purge the double-sided power generation photovoltaic panel 52 in the tilted state, and use its tilted state characteristics to blow away the obstacles on the surface.

[0035] As Figures 1 to 11As shown, the double-sided photovoltaic panel module 5 includes a third U-shaped side frame 51 fitted and installed at the open end of the second U-shaped side frame 41. Inside the open end of the third U-shaped side frame 51, a double-sided power generation photovoltaic panel 52 is fixedly installed. At both side ends of the third U-shaped side frame 51, contact type clamping plates 53 are fixedly installed. The wiring end of the double-sided power generation photovoltaic panel 52 is placed at the inner bottom of the contact type clamping plate 53 and is connected to the contact at the bottom of the contact type clamping plate 53. On both side edges of the open end of the second U-shaped side frame 41, contact type fitting bases 410 that are fitted with the contact type clamping plates 53 are fixedly installed.

[0036] Among them, the configured contact type clamping plates 53 and contact type fitting bases 410 are structures in the prior art that can interact through connection and can work after fitting contact. They belong to the double-contact card connector structure. Their contacts are embedded in the insulating support, and the up and down floating is realized through the return spring to adapt to the position deviation during plugging and unplugging, so as to realize the free disassembly of the double-sided power generation photovoltaic panel 52 and the characteristic that each double-sided power generation photovoltaic panel 52 works independently, without affecting the normal work of other double-sided power generation photovoltaic panels 52 during maintenance and replacement.

[0037] As Figures 1 to 11 shown, a secondary light guiding mechanism 6 is fixedly installed at the inner bottom of the open end of the second U-shaped side frame 41. The secondary light guiding mechanism 6 includes a base partition plate 61. At the bottom surface of the base partition plate 61, an airbag 64 is fixedly installed. At the bottom of the airbag 64, a third light guiding tube 65 is fixedly installed. On both sides of the upper surface of the base partition plate 61, first light guiding tubes 62 are fixedly installed. An inner light transmitting flexible bag 66 is connected in communication between the first light guiding tube 62 and the third light guiding tube 65. At the inner bottom of the open end of the second U-shaped side frame 41, a second light guiding cavity 49 that covers the outside of the first light guiding tube 62 is fixedly installed. On both sides of the second light guiding cavity 49, first light guiding cavities 48 are fixedly installed. The first light guiding cavity 48 is a U-shaped cavity structure. The sides of the second light guiding cavity 49 and the first light guiding cavity 48 facing the double-sided power generation photovoltaic panel 52 are both inclined transparent layers 411.

[0038] Among them, the bottom of the configured second U-shaped side frame 41 is open. During the process of the airbag 64 being filled with gas and expanding and unfolding outward, the third light guide tube 65 at the bottom can be pushed outwards from the open end at the bottom of the second U-shaped side frame 41. The configured first light guide tube 62, second light guide tube 63, and third light guide tube 65 are all conduit structures in the prior art that are transparent and can utilize a coating to reflect sunlight. They are made of a high-reflectivity material, such as silver-coated polyester, and are responsible for transmitting light to the target area through multiple total internal reflections. The inner light-transmitting flexible bag 66 is different from the rigidity of the first light guide tube 62, second light guide tube 63, and third light guide tube 65. As a whole, it is a light guide bag structure that can be stretched and elongated, and a reflective coating is provided on the inner wall of the bag.

[0039] As Figures 1 to 11 As shown, both side ends of the first light guide tube 62 are connected to the second light guide tube 63 in a communicating manner. The first light guide tube 62 and the second light guide tubes 63 at both side ends together form a U-shaped structure. The second light guide tubes 63 at both side ends are entirely placed inside the first light guide cavity 48 and are close to the inclined transparent layer 411 side. The inner cavities of the first light guide cavity 48 and the second light guide cavity 49 are in communication, and a number of air injection holes 412 are sequentially arranged and installed on the inclined transparent layers 411 of the first light guide cavity 48 and the second light guide cavity 49.

[0040] Among them, the configured inclined transparent layer 411 is a transparent plate structure in an inclined state. The purpose of the inclination is to enable the transmitted light to irradiate more directly on the double-sided power generation photovoltaic panel 52, and it can also enable the air injection holes 412 to act more directly on the double-sided power generation photovoltaic panel 52.

[0041] As Figures 1 to 11 As shown, a servo air compressor 12 is fixedly installed at a position below the third gear disk 10 inside the junction box 1. Two third air supply hoses 13 are fixedly installed on the output end of the servo air compressor 12. A first air supply hose 37 that is connected to each push-button valve head port 34 is fixedly installed inside the fitting area 32. The third air supply hose 13 is connected to the first air supply hose 37 to supply air to different push-button valve head ports 34. The inner connecting rigid tube 46 is integrally L-shaped and penetrates into the first light guide cavity 48 on the side of the second U-shaped side frame 41 through the cavity disk 42. Both sides of the airbag 64 are connected to the second air supply hoses 67 in a communicating manner. The second air supply hoses 67 respectively penetrate into the first light guide cavities 48 on both sides, and a gas guide open mask 68 is fixedly installed at the end that penetrates into the first light guide cavity 48.

[0042] The configured airbag 64 is a bag structure with shrinkability in the prior art. It can expand and extend when inflated inside, and will shrink when not inflated as a whole. In the shrunk state, its third light guide tube 65 will be received into the inner bottom of the second U-shaped side frame 41, and will not interfere with the fitting state of the bottom of the second U-shaped side frame 41 in each adjustment area when vertical.

[0043] Among them, the specific usage process of the configured double-sided photovoltaic panel module 5 is as follows: First, through the rotation of the second gear disc 8 at the output end of the servo motor 7, the third gear disc 10 on the upper part is linked through the crawler sleeve 9, and the extension rods 11 on both sides are controlled to drive the threaded rod 35 to rotate, so that the nut sleeves 45 engaged on each adjustment area move, and the second U-shaped side frame 41 is tilted. In the tilted state, through the contact type clamping plates 53 on both sides of the third U-shaped side frame 51, the double-sided power generation photovoltaic panels 52 are sequentially fitted and installed on the second U-shaped side frames 41 in different adjustment areas, and are connected through the contact type fitting base 410. According to the working state, it can be divided into a vertical state and an adaptive light tilt state.

[0044] In the vertical state: Through the driving action of the threaded rod 35, the nut sleeve 45 in each adjustment area is docked at the exact middle position of this adjustment area. At this time, the second U-shaped side frame 41 is equivalent to the junction box 1 in a vertical state, as shown in the Figure 2 specification appendix. In this state, the double-sided power generation photovoltaic panels 52 in each adjustment area form a whole photovoltaic panel, which is vertically installed on the structure as a whole, playing the role of protection and isolation fence, and generating electricity by relying on the direct sunlight on the front side and the reflected light on the ground. In the adaptive light tilting state: Similarly, under the driving action of the threaded rod 35, the nut sleeves 45 on each adjustment area are controlled to move synchronously. When the nut sleeve 45 moves upward, the cavity disk 42 rotates clockwise with the first gear disk 44 engaged with the side tooth plate 33, causing the second U-shaped side frame 41 to rotate clockwise. Similarly, when the nut sleeve 45 on each adjustment area is controlled to move downward, at this time, the cavity disk 42 rotates counterclockwise with the first gear disk 44 engaged with the side tooth plate 33, causing the second U-shaped side frame 41 to rotate counterclockwise. During the day, according to the geographical location and the rising and setting directions of the sun, different driving instructions can be sent to the servo motor 7 in real time, so that the double-sided power generation photovoltaic panel 52 can adaptively tilt following the angle of sunlight. After tilting on each side, using the interval difference between the upper and lower adjustment areas, the front sides of the double-sided power generation photovoltaic panels 52 in each adjustment area can be evenly irradiated. And after attaching a reflective coating to the surface of the second U-shaped side frame 41, the reflective plate 14 on the surface of the junction box 1 and the reflective coatings of the second U-shaped side frames 41 in each adjustment area can also be used to irradiate the back sides of the double-sided power generation photovoltaic panels 52 in each adjustment area, improving the light-receiving area of this system.

[0045] Among them, for the vertical state and the adaptive light tilting state, it can be changed according to the assembly requirements. For example, when there are impurities such as snow accumulation on the surface of the double-sided power generation photovoltaic panel 52, or when the air barrier in this area has a greater impact and ventilation is required, or when the working effect is poor when the back side of the double-sided power generation photovoltaic panel 52 is working under the ground reflected light, it can be switched between the vertical state and the tilting state to adapt to the installation environment.

[0046] Furthermore, in the tilting state, when the cavity disk 42 rotates to the outermost position of the adjustment area, its convex sealing interface 43 will connect to the push-button valve head port 34 at this position. After connecting the valve head, the servo air compressor 12 can be controlled to open the output end. Using the third air delivery hose 13 and the first air delivery hose 37, air is injected into this valve head end. The injected gas enters the internal connecting hard pipe 46 inside the convex sealing interface 43 through the push-button valve head port 34, and enters the first light guide cavity 48 through the internal connecting hard pipe 46. The high-speed air flow entering the first light guide cavity 48 can enter the second light guide cavity 49, and is blown onto the surface of the double-sided power generation photovoltaic panel 52 through the air holes 412 on the side of the second light guide cavity 49 and the first light guide cavity 48. On the one hand, this air duct can effectively remove the interference impurities on the surface in cooperation with the tilting state, and on the other hand, it can effectively take away the heat of the double-sided power generation photovoltaic panel 52, especially the reflected heat, because in the reflection state, the heat is more concentrated, so as to ensure the stability of the photovoltaic surface.

[0047] Synchronously, it enters the air duct in the first light guide cavity 48, then enters the air guide open mask 68, and is transported to the inside of the airbag 64 through the second air supply hose 67 at the bottom of the air guide open mask 68, inflating the airbag 64 and causing the third light guide tube 65 at the bottom to extend outwards. In the tilted state of the second U-shaped side frame 41, the extended third light guide tube 65 can effectively reflect light through the inner light-transmitting flexible bag 66 into the first light guide tube 62 and the second light guide tube 63, and is reflected onto the double-sided power generation photovoltaic panel 52 through the inclined transparent layer 411 close to the first light guide tube 62 and the second light guide tube 63, further enhancing the illumination effect on the surface of the double-sided power generation photovoltaic panel 52.
