Abstract

The present invention discloses an integrated photovoltaic railing and its use method, belonging to the technical field of photovoltaic railings. The integrated railing comprises a junction box, a bottom junction box, and a self-adjusting frame module. The junction box, the bottom junction box on both sides, and the self-adjusting frame module form a U-shaped frame structure. A plurality of independent flip frame mechanisms are provided at the open ends of the U-shaped frame structure through the self-adjusting frame modules. Each flip frame mechanism is equipped with an independent bifacial photovoltaic panel module. Through the dynamic coordination structure of the self-adjusting frame module and the flip frame mechanism, the built-in gear meshing and threaded rod transmission structure are utilized to achieve synchronous tilt adjustment of the bifacial photovoltaic panels.

Compared with the existing technology that strongly relies on ground reflectivity, the bifacial power generation efficiency is significantly improved by the complementary mechanism of front direct light capture and back scattered light.

Description

Technical Field

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

[0002] In existing technologies, bifacial photovoltaic modules used in applications such as building guardrails and balcony railings are known as bifacial photovoltaic fences or guardrails. These products typically utilize high-efficiency heterojunction cell technology and integrate large-scale monocrystalline BC technology to achieve bifacial power generation. Vertically mounted photovoltaic glass modules are integrated with the railing base and columns, generating electricity from direct sunlight from the front and reflected light from the back, achieving integrated building enclosure and photovoltaic power generation. The core technology lies in embedding photovoltaic glass into the railing structure, utilizing the light-transmitting properties of the gaps between the cells to meet lighting requirements. However, due to the vertical installation method, the backside power generation efficiency depends on the ground reflectivity and ambient light intensity.

[0003] However, this type of integrated photovoltaic guardrail is limited by the vertical installation method, and its back-side power generation efficiency is more dependent on the surface reflectivity and ambient light. In addition, BC technology combined with the vertical installation mode of double-sided heterojunction cells is used in building curtain walls or open balcony scenes with high ventilation requirements. Such areas are often made of permeable bricks and green grass, and their reflectivity is very low, resulting in insufficient back-side power generation gain. Although existing technologies can try to alleviate the ventilation and light transmission problems by optimizing the transmittance of the cell gap, they still cannot break through the fundamental contradiction of the limited light range on the back under vertical installation.

[0004] Although the cell gap area allows some light to penetrate, the cell coverage area still forms a partial blockage, resulting in the reflected light actually received on the back side only covering a limited area. In urban buildings with large reflectivity fluctuations, fixed-angle components cannot dynamically adjust the light-receiving surface, which will cause the overall power generation efficiency to fluctuate beyond the design threshold. Although the back gain can be improved by simply increasing the height of the junction box bracket or using a high-reflectivity coating, the structural stability and space utilization are sacrificed, and the coupling contradiction between ventilation and power generation efficiency is not resolved. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an integrated photovoltaic railing and a method of use thereof, aiming to solve the above technical problems.

[0008] The self-adjusting frame module includes a first U-shaped side frame, and the flip frame mechanism includes a second U-shaped side frame movably mounted in the first U-shaped side frame, and first gear plates are configured on both sides of the second U-shaped side frame, and side tooth plates meshing with the first gear plates are configured on the inner wall of the first U-shaped side frame, so that the second U-shaped side frame rotates by utilizing the meshing relationship between the first gear plate and the side tooth plates during the up and down movement inside the first U-shaped side frame, thereby controlling the synchronous rotation of the second U-shaped side frame to tilt the double-sided photovoltaic panel module;

[0009] The double-sided photovoltaic panel module includes double-sided photovoltaic panels, and the up and down movement of the second U-shaped side frame causes several double-sided photovoltaic panels to rotate synchronously to achieve an overall vertical and dispersed inclined arrangement state.

When the nut sleeve is located in the middle of the adjustment area, the two convex sealing interfaces are located directly above and below the nut sleeve, and at this time the second U-shaped side frame is in a vertical state relative to the junction box; a level detector is fixedly installed in the cavity inside the cavity disk, and two internal hard pipes communicating with the two convex sealing interfaces are fixedly installed on the side of the level detector, and a reflector is press-installed at the middle position of the upper surface of the junction box.

[0014] As a further solution of the present invention: the double-sided photovoltaic panel module includes a third U-shaped side frame embedded in the open end of the second U-shaped side frame, and a double-sided power generation photovoltaic panel is fixedly installed on the inner side of the open end of the third U-shaped side frame. Contact-type snap-in plates are fixedly installed at both side ends of the third U-shaped side frame. The connection terminals of the double-sided power generation photovoltaic panels are placed on the inner bottom of the contact-type snap-in plates and are connected to the contacts at the bottom of the contact-type snap-in plates. Contact-type embedding bases embedded with the contact-type snap-in plates are fixedly installed on both side edges of the open end of the second U-shaped side frame.

[0015] 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, and 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, and a third light-guiding tube is fixedly installed on the bottom of the airbag bag. The first light-guiding tube is fixedly installed on both sides of the upper surface of the base partition plate, and 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, and 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.

[0016] As a further solution of the present invention: both side ends of the first light guide tube are connected to the second light guide tube, the first light guide tube and the second light guide tubes at both side ends form a U-shaped structure as a whole, and the second light guide tubes at both side ends are placed as a whole inside the first light guide cavity and close to one side of the oblique transparent layer, the first light guide cavity is connected to the inner cavity of the second light guide cavity, and a plurality of air transmission holes are arranged in sequence on the oblique transparent layers of the first light guide cavity and the second light guide cavity.

[0017] As a further solution of the present invention: a servo air compressor is fixedly installed at a position below the third gear plate inside the junction box, and two third air supply hoses are fixedly installed on the output end of the servo air compressor. A first air supply hose connected to each push-type valve head port is fixedly installed inside the fitting area, and the third air supply hose is connected to the first air supply hose to supply air to different push-type valve head ports. The internal hard pipe is L-shaped as a whole, and passes through the first light-guiding cavity on the side of the second U-shaped side frame through the cavity disk. Both sides of the airbag bag are connected to the second air supply hose, and the second air supply hose passes through the first light-guiding cavity on both sides respectively, and an air guide opening mask is fixedly installed on one end that passes through the first light-guiding cavity.

[0018] A method for using an integrated photovoltaic railing comprises the following steps:

[0019] S1: First, the servo motor drives the second and third gear plates to rotate synchronously, driving the extension rod and the threaded rod to rotate. The rotation of the threaded rod passes through the adjustment zones divided by the partition plate, causing the nut sleeves in each adjustment zone to move up and down along the threaded rod, driving the second U-shaped side frame to move within the self-adjusting frame module;

[0020] S2: Then, when the second U-shaped side frame moves, the first gear plates on both sides thereof engage with the side gear 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, thereby controlling the tilt angle of the bifacial photovoltaic panel module;

[0021] S3: Then, when the second U-shaped side frame is tilted to the maximum angle, the convex sealing interface presses the push-type valve head port, starting the servo air compressor to inject air into the first light guide cavity through the hose. The air flow blows the surface of the double-sided photovoltaic panel through the air delivery hole, and at the same time, the air bag is inflated through the second air delivery hose, pushing the third light guide tube out;

[0022] S4: Finally, the extended third light pipe transmits the reflected light from the ground to the first and second light pipes through the inner light-transmitting flexible bag, and then reflects it twice to the back of the double-sided photovoltaic panel through the oblique transparent layer. The level detector monitors the tilt status in real time and cooperates with the servo motor closed-loop adjustment to realize automatic switching between the vertical protection mode and the inclined power generation mode.

[0023] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0024] (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 is highly dependent 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, and the light-guiding mechanism is combined to guide the reflected light to the back battery area for a second time. In low-reflectivity scenes such as green grass, it can still maintain a stable power generation gain, solving the core contradiction of the vertical installation mode where the back light is limited.

[0025] (2) The integrated design of ventilation, heat dissipation and self-cleaning effectively resolves the coupling conflict between the structure and performance of photovoltaic guardrails. The continuous air duct formed by the interval tilt can disperse the wind pressure while reducing the temperature rise of the components. In conjunction with aerodynamic cleaning, the high-pressure airflow is triggered to be ejected through the light-guiding cavity at the maximum tilt angle, and the surface dust removal and snow removal are completed simultaneously. It avoids the power generation attenuation caused by poor ventilation of traditional vertical structures, and realizes the coordinated optimization of heat dissipation efficiency and light energy utilization through the integrated design of airflow path and light-guiding channel. It is particularly suitable for high-wind-speed coastal areas and dusty and sandy environments.

[0026] It adopts independent double-sided photovoltaic panel modules and contact-type quick connection design, which supports live plugging and unplugging maintenance of individual components without affecting overall operation. The light-guiding mechanism is driven by airbags to achieve adaptive extension, and the reflected light from the ground is directed to the back of the photovoltaic system in a tilted state, thereby improving the back power generation efficiency in low-reflectivity scenarios. Combined with the closed-loop control of the servo motor and the level detector, the system can autonomously switch between vertical protection mode and tilted power generation mode.

[0046] As shown in the figure, in order to clearly implement the structure of the embodiment of the present invention, specific structures and devices are marked in the figure, but this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. According to specific needs, ordinary technicians in this field can adjust or modify these devices and environments. DETAILED DESCRIPTION

[0047] The following describes in detail an integrated photovoltaic railing and its use method provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations. Furthermore, the accompanying drawings are intended only to more specifically illustrate the embodiments and are not intended to limit the present invention.

[0048] like Figures 1 to 11 As shown, an embodiment of the present invention provides an integrated photovoltaic railing, including a junction box 1, bottom junction boxes 2 are fixedly installed at both ends of the upper surface of the junction box 1, and self-adjusting frame modules 3 are fixedly installed on the upper side of the bottom junction box 2. The junction box 1 and the bottom junction boxes 2 on both sides and the self-adjusting frame modules 3 form a U-shaped frame structure, and a plurality of independent flip frame mechanisms 4 are sleeved at the open ends of the U-shaped frame structure through the self-adjusting frame modules 3, and each flip frame mechanism 4 is configured with an independent double-sided photovoltaic panel module 5;

[0049] The self-adjusting frame module 3 includes a first U-shaped side frame 31, and the flip frame mechanism 4 includes a second U-shaped side frame 41 movably mounted in the first U-shaped side frame 31, and first gear plates 44 are disposed on both sides of the second U-shaped side frame 41. Side tooth plates 33 that engage with the first gear plates 44 are disposed on the inner wall of the first U-shaped side frame 31, so that the second U-shaped side frame 41 rotates by virtue of the engagement between the first gear plates 44 and the side tooth plates 33 during the up and down movement of the second U-shaped side frame 41 inside the first U-shaped side frame 31, thereby controlling the synchronous rotation of the second U-shaped side frame 41 to tilt the bifacial photovoltaic panel module 5;

[0050] The double-sided photovoltaic panel module 5 includes double-sided photovoltaic panels 52 . By moving the second U-shaped side frame 41 up and down, the double-sided photovoltaic panels 52 are rotated synchronously to achieve an overall vertical and dispersed tilted arrangement state.

[0051] In order to solve the problem that the existing vertically installed double-sided photovoltaic guardrail is unable to dynamically adapt to the fluctuation of ground reflectivity and the shading of solar cells, resulting in limited light on the back side, and poor ventilation exacerbates the temperature rise, making it difficult to coordinately optimize the power generation efficiency and heat dissipation efficiency, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution mainly consists of a junction box 1, a bottom junction box 2, a self-adjusting frame module 3, a flip frame mechanism 4, and a double-sided photovoltaic panel module 5. The junction box 1 and the bottom junction box 2 are cavity structures used in the prior art for connecting transmission cables and electrical components, ensuring that the electrodes of the busbars leading from the solar cells are connected to the terminal here to form a current output node. Generally, MC4 or similar waterproof connectors can be selected to facilitate quick plugging and unplugging of cables on site. The configured self-adjusting frame module 3 is a U-shaped frame structure with a built-in linkage element. On the one hand, it is used to support several double-sided photovoltaic panel modules 5 on the inside, and on the other hand, it is used to control the synchronous rotation of several double-sided photovoltaic panel modules 5 through the built-in linkage element, so that the configured several double-sided photovoltaic panel modules 5 can be perpendicular to the junction box as a whole, or can be tilted and spread out separately, as shown in the attached manual. Figure 11As shown, in the operational and installed state, efficient space utilization can be achieved, and it is particularly suitable for land-sensitive areas, such as fences, soundproof walls or building exterior walls in the prior art, which have power generation, privacy protection and decorative functions. For example, photovoltaic guardrails on highways can reduce noise and reduce land occupation. In the vertical state, because the power generation on the back is highly dependent on the ground material, it can be switched to a servo-tilt adjustable state. In this state, it can not only be optimized through dynamic tilt angle, but also different from the strong dependence of traditional vertical photovoltaic guardrails on ground reflectivity. It can also be based on the synergistic efficiency of bifacial components, by directly receiving direct light capture on the front side and expanding the ground reflected light reception range on the back side through the tilt angle, while using scattered light to compensate. Compared with the vertically installed fixed shading strip, the partition design reduces shadow obstruction between panels, and adaptively tilts under different illumination angles of morning and evening sunlight, effectively alleviating the contradiction of the cell coverage area blocking the backlight side. In addition, through the spacing layout, air ducts can be naturally formed between the panels, and the contradiction between heat dissipation and ventilation coupling of vertical installation can be solved simultaneously. It can not only reduce the temperature rise of the components and avoid the wind speed attenuation caused by the closed vertical structure, but also disperse the wind pressure in terms of wind resistance. It is especially suitable for use in areas with high wind loss at coastal stations, which expands the deployment scenarios of photovoltaic systems. In addition, due to the structure of the photovoltaic guardrail and the particularity of the work, after installation, except for the necessary daily maintenance work, it is basically in an unmanned working state. It is well known that photovoltaic power generation depends on the irradiated area of the photovoltaic surface. There is not only dust but also weather interference outdoors, especially snow interference. Its inclined separation installation can also be tilted during work, and has the characteristics of self-cleaning and anti-snow accumulation. It is also different from vertical installation and can greatly reduce the loss of power generation due to snow accumulation. Therefore, the self-adjusting frame module 3 and the flip frame mechanism 4 have a linked rotation adjustment feature. It can achieve the effect of coordinated regulation of light, heat and wind on the double-sided photovoltaic panel 52, providing more stable photovoltaic guardrails for high wind speed areas, cities with fluctuating reflectivity and ecologically sensitive areas.

[0052] like 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 plate 8 is fixedly installed on the output end, and a third gear plate 10 is movably installed at a position on the opposite side of the second gear plate 8 inside the junction box 1, and the outer surface of the third gear plate 10 is covered with a track sleeve 9 that engages with the second gear plate 8, and an extension rod 11 that movably passes through the top of the junction box 1 is fixedly installed at the center position of the upper surface of the third gear plate 10 and the second gear plate 8, and the extension rod 11 extends upward and passes through the bottom junction box 2 and extends into the inner bottom of the first U-shaped side frame 31.

[0053] Among them, the configured servo motor 7 is a structure capable of servo drive in the prior art. In the working state, it can control the second gear plate 8 at its output end to perform servo rotation. In the non-working state, the second gear plate 8 at the output end does not rotate. Through the outer meshing track sleeve 9, the third gear plate 10 can be synchronously linked to make the extension rods 11 at the driving ends on both sides rotate synchronously.

[0054] like Figures 1 to 11 As shown, the first U-shaped side frame 31 is U-shaped as a whole, and the open ends of the first U-shaped side frames 31 on both sides are facing the center of the junction box 1, and a fitting area 32 is provided on the inner side of the open end of the first U-shaped side frame 31, and a threaded rod 35 is movably installed at the axial position of the fitting area 32, and the bottom of the threaded rod 35 is fixedly connected to the extension rod 11 extending from the bottom of the first U-shaped side frame 31, and a plurality of partition plates 36 are fixedly installed on the outer surface of the threaded rod 35 in sequence, and the threaded rod 35 is divided into a plurality of independent equal-length areas by the partition plates 36, and each separated equal-length area is used as an adjustment area, and a push-type valve head port 34 is fixedly installed on the side wall of one side of the fitting area 32 at the positions at both ends of each adjustment area, and a side tooth plate 33 is fixedly installed on the side wall of the fitting area 32 on the side opposite to the side where the push-type valve head port 34 is configured.

[0055] Among them, the configured first U-shaped side frame 31 is U-shaped as a whole, and the configured press-type valve head mouth 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 subsequently rotated cavity disk 42, it can be communicated with the convex sealing interface 43 in the pressed state to form a temporary connecting air channel. 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 several independent equal-length areas by the separating disk 36 in order to limit the flipping range of the flip frame mechanism 4 in each separated area.

[0056] like Figures 1 to 11 As shown, the flip frame mechanism 4 also includes a cavity disk 42 fixedly mounted at the middle position on both sides of the second U-shaped side frame 41, and each second U-shaped side frame 41 is movably mounted on each adjustment area in the fitting area 32 through the cavity disk 42 on both sides. A first gear disk 44 is fixedly mounted at the outer center position of the cavity disk 42, and the side edge of the first gear disk 44 is engaged with the side tooth plate 33 on the side wall of the fitting area 32. A nut sleeve 45 is movably mounted at the outer center position of the first gear disk 44, and the nut sleeve 45 is engaged and mounted on the threaded rod 35 of each adjustment area.

[0057] Among them, the configured threaded rod 35 can utilize the effect of the screw drive during the rotation process to synchronously drive the nut sleeve 45 in each adjustment area to move up and down, so as to control the second U-shaped side frame 41 to move up and down inside the bracket. In the process of each up and down movement, in conjunction with the effect of the engagement of the upper side tooth plate 33 on the side, the first gear plate 44 is linked to rotate, so as to control the second U-shaped side frame 41 to move up and down inside the bracket while rotating, thereby achieving the effect of subsequent adaptive tilting.

[0058] like Figures 1 to 11 As shown, the flip frame mechanism 4 also includes two convex sealing interfaces 43 fixedly mounted on the outer edge of the cavity disk 42, which are 180 degrees apart. When the nut sleeve 45 is located in the middle of the adjustment area, the two convex sealing interfaces 43 are located directly above and below the nut sleeve 45, and at this time the second U-shaped side frame 41 is in a vertical state relative to the junction box 1; a level detector 47 is fixedly mounted in the cavity inside the cavity disk 42, and two internal hard pipes 46 communicating with the two convex sealing interfaces 43 are fixedly mounted on the side of the level detector 47, and a reflector 14 is press-mounted at the middle position of the upper surface of the junction box 1.

[0059] Among them, the configured convex sealing interface 43 and the cavity disk 42 are an integrated structure, which protrudes outward as a whole and presses the press-type valve head port 34 during the rotation. By configuring the convex sealing interface 43 on the outer edge of the cavity disk 42 and ensuring that the nut sleeve 45 is located in the middle of the adjustment area, the two convex sealing interfaces 43 are located directly above and below the nut sleeve 45, and at this time the second U-shaped side frame 41 is in a vertical state relative to the junction box 1. In actual working process, when the nut sleeve 45 is located in the 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 of being relative to the junction box 1, and the overall structure has an arrangement effect, and on the threaded rod 35 During the clockwise and counterclockwise rotation, the nut sleeve 45 can be controlled to move up and down. During the movement, the cavity disk 42 rotates under the action of the engagement of the first gear disk 44 and the side tooth plate 33. When it rotates to the two ends of the adjustment area, the convex sealing interfaces 43 on both sides will approach the press-type valve head port 34 and press it down. Specifically, when the double-sided photovoltaic panel module 5 is tilted to the maximum angle, the press-type valve head port 34 will be connected, so that the airway is injected into the first light guide cavity 48 and the second light guide cavity 49 through the cavity disk 42. The first light guide cavity 48 and the second light guide cavity 49 are used to purge the tilted double-sided photovoltaic panel 52, and the obstructions on the surface are blown away by the characteristics of its tilted state.

[0060] like Figures 1 to 11As shown, the double-sided photovoltaic panel module 5 includes a third U-shaped side frame 51 embedded in the open end of the second U-shaped side frame 41, and a double-sided photovoltaic panel 52 is fixedly installed on the inner side of the open end of the third U-shaped side frame 51. Contact-type snap-in plates 53 are fixedly installed at both side ends of the third U-shaped side frame 51. The connection terminals of the double-sided photovoltaic panel 52 are placed on the inner bottom of the contact-type snap-in plate 53 and are connected to the contacts at the bottom of the contact-type snap-in plate 53. Contact-type embedding bases 410 embedded with the contact-type snap-in plate 53 are fixedly installed on both side edges of the open end of the second U-shaped side frame 41.

[0061] Among them, the configured contact-type snap-in plate 53 and the contact-type interlocking base 410 are structures in the prior art that can interact by being connected, and can work after interlocking contact. They belong to a double-contact card board connector structure, and their contacts are embedded in insulating supports. They float up and down through reset springs to adapt to position deviations during plugging and unplugging, so as to realize the free disassembly of the double-sided photovoltaic panel 52 and the characteristics that each double-sided photovoltaic panel 52 works independently, and will not affect the normal operation of other double-sided photovoltaic panels 52 during maintenance and replacement.

[0062] like Figures 1 to 11 As shown, a secondary light-guiding mechanism 6 is fixedly installed on the bottom inner side of the open end of the second U-shaped side frame 41, and the secondary light-guiding mechanism 6 includes a base partition plate 61, and an airbag bag 64 is fixedly installed on the bottom surface of the base partition plate 61, and a third light-guiding tube 65 is fixedly installed on the bottom of the airbag bag 64. The first light-guiding tube 62 is fixedly installed on both sides of the upper surface of the base partition plate 61, and the first light-guiding tube 62 and the third light-guiding tube 65 are connected to each other by an inner light-transmitting tough bag 66. The second light-guiding cavity 49 covering the outside of the first light-guiding tube 62 is fixedly installed on the bottom inner side of the open end of the second U-shaped side frame 41, and the first light-guiding cavity 48 is fixedly installed on both sides of the second light-guiding cavity 49. The first light-guiding cavity 48 is a U-shaped cavity structure, and the sides of the second light-guiding cavity 49 and the first light-guiding cavity 48 facing the double-sided photovoltaic panel 52 are both oblique transparent layers 411.

[0063] Among them, the bottom of the configured second U-shaped side frame 41 is open. When the airbag bag 64 is filled with gas and expands, the third light guide tube 65 at the bottom can be pushed outward from the open end of the bottom of the second U-shaped side frame 41 during the outward expansion process. The configured first light guide tube 62, second light guide tube 63, and third light guide tube 65 are all transparent conduit structures in the prior art that can use the coating to reflect sunlight. They are made of high-reflectivity materials such as silver-coated polyester, and are responsible for transmitting light to the target area through multiple total reflections. The inner light-transmitting tough bag 66 is different from the rigidity of the first light guide tube 62, the second light guide tube 63, and the third light guide tube 65. The whole is a light guide bag structure that can be retracted and stretched, and the inner wall of the bag is provided with a reflective coating.

[0064] like 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, and the first light guide tube 62 and the second light guide tubes 63 at both side ends form a U-shaped structure as a whole, and the second light guide tubes 63 at both side ends are placed as a whole inside the first light guide cavity 48 and close to the side of the oblique transparent layer 411. The inner cavity of the first light guide cavity 48 is connected to the second light guide cavity 49, and a plurality of air transmission holes 412 are arranged in sequence on the oblique transparent layers 411 of the first light guide cavity 48 and the second light guide cavity 49.

[0065] The configured oblique transparent layer 411 is a transparent plate structure in an inclined state. The purpose of the inclination is to allow the transmitted light to be more directly irradiated on the double-sided photovoltaic panel 52, and also to allow the gas transmission holes 412 to act more directly on the double-sided photovoltaic panel 52.

[0066] like Figures 1 to 11 As shown, a servo air press 12 is fixedly installed inside the junction box 1 at a position below the third gear disk 10, and two third air supply hoses 13 are fixedly installed on the output end of the servo air press 12. A first air supply hose 37 connected to each push-type 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-type valve head ports 34. The internal hard tube 46 is L-shaped as a whole, and passes through the first light-guiding cavity 48 on the side of the second U-shaped side frame 41 through the cavity disk 42. Both sides of the airbag bag 64 are connected to the second air supply hose 67, and the second air supply hose 67 passes through the first light-guiding cavity 48 on both sides respectively, and an air guide opening cover 68 is fixedly installed on one end passing through the first light-guiding cavity 48.

[0067] The configured airbag bag 64 is a contractile bag structure in the prior art. It can expand and extend when it is inflated, and will shrink as a whole when it is not inflated. In the contracted state, its third light guide tube 65 will be retracted into the inner bottom of the second U-shaped side frame 41, and will not interfere with the bottom fitting state of the second U-shaped side frame 41 of each adjustment area when vertically facing.

[0068] The specific usage process of the configured double-sided photovoltaic panel module 5 is as follows:

[0069] First, by rotating the second gear plate 8 at the output end of the servo motor 7, the third gear plate 10 is linked to the track sleeve 9 to control the extension rods 11 on both sides to drive the threaded rod 35 to rotate, so that the engaged nut sleeves 45 on each adjustment area are moved, and the second U-shaped side frame 41 is tilted. In the tilted state, the double-sided photovoltaic panels 52 are sequentially embedded and installed on the second U-shaped side frames 41 in different adjustment areas through the contact-type locking plates 53 on both sides of the third U-shaped side frame 51, and are connected to the work through the contact-type embedding base 410. According to the working state, it can be divided into a vertical state and an adaptive light tilt state.

[0070] In the vertical state: through the driving action of the threaded rod 35, the nut sleeve 45 on each adjustment area is parked at the middle position of the adjustment area. At this time, the second U-shaped side frame 41 is equivalent to the junction box 1 in the vertical state, as shown in the appendix of the manual. Figure 2 As shown, in this state, the double-sided photovoltaic panels 52 on each adjustment area form a whole photovoltaic panel, which is vertical on the structure as a whole, plays the role of protection and isolation, and relies on direct sunlight from the front and reflected light from the ground to generate electricity;

[0071] In the adaptive light tilt state: the nut sleeve 45 on each adjustment area is controlled to move synchronously by the driving action of the threaded rod 35. When the nut sleeve 45 moves upward, the cavity disk 42 rotates clockwise when the first gear disk 44 is engaged with the side gear plate 33, so that the second U-shaped side frame 41 rotates clockwise. Similarly, when the nut sleeve 45 on each adjustment area moves downward, the cavity disk 42 rotates counterclockwise when the first gear disk 44 is engaged with the side gear plate 33, so that the second U-shaped side frame 41 rotates counterclockwise. During the day, according to the geographical location and The rising and setting direction of the sun transmits different drive instructions to the servo motor 7 in real time, so that the double-sided photovoltaic panel 52 can be adaptively tilted according to the angle of sunlight. After tilting on each side, the gap difference between the upper and lower adjustment areas can be used to evenly expose the front of the double-sided photovoltaic panel 52 in each adjustment area. After the reflective coating is attached 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 coating of the second U-shaped side frame 41 on each adjustment area can also be used to illuminate the back of the double-sided photovoltaic panel 52 in each adjustment area, thereby increasing the light-receiving area of the system.

[0072] Among them, the vertical state and the adaptive light tilt state can be changed according to the assembly needs. For example, when there are impurities such as snow and other obstructions on the surface of the double-sided photovoltaic panel 52, or the air blocked in the area has a large impact and ventilation is required, or when the back of the double-sided photovoltaic panel 52 is affected by the reflected light from the ground and the working effect is poor, you can switch between the vertical state and the tilted state to adapt to the installation environment.

[0073] Furthermore, in the tilted state, the cavity disk 42 rotates to the sidemost end of the adjustment area, and its convex sealing interface 43 will connect to the push-type valve head port 34 at this position. After the valve head is connected, the servo air compressor 12 can be controlled to open the output end, and the third gas supply hose 13 and the first gas supply hose 37 are used to inject gas into the valve head end. The injected gas enters the internal hard tube 46 on the inner side of the convex sealing interface 43 through the push-type valve head port 34, and enters the first light guide cavity 48 through the internal hard tube 46. The high-speed airflow entering the first light guide cavity 48 can communicate and enter the second light guide cavity 49, and blow toward the surface of the bifacial photovoltaic panel 52 through the gas supply holes 412 on the sides of the second light guide cavity 49 and the first light guide cavity 48. On the one hand, this air duct can effectively remove interfering impurities on the surface in conjunction with the tilted state, and on the other hand, it can effectively take away the heat of the bifacial photovoltaic panel 52, especially the reflected heat, because in the reflective state, the heat is more concentrated to ensure the stability of the photovoltaic surface.

[0074] Synchronously, the air duct entering the first light guide cavity 48 will enter the air guide open cover 68, and be transported to the interior of the air bag 64 through the second air supply hose 67 at the bottom of the air guide open cover 68, expanding the air bag 64, causing it to drive the third light guide tube 65 at the bottom to extend outward. When the second U-shaped side frame 41 is tilted, the extended third light guide tube 65 can effectively reflect the light through the inner transparent tough bag 66 to the first light guide tube 62 and the second light guide tube 63, and reflect it to the double-sided power generation photovoltaic panel 52 through the oblique transparent layer 411 close to the first light guide tube 62 and the second light guide tube 63, further increasing the effect of the illumination of the surface of the double-sided power generation photovoltaic panel 52.
