According to an embodiment of the present invention, referring to fig. 1 to 4, a photovoltaic support for a double-sided module includes a plurality of columns 100, at least one main beam 200, and a plurality of purlins 300. The pillars 100 are spaced on the base 600, the main beams 200 are rotatably assembled on the top of the pillars 100, and the purlins 300 are spaced on the main beams 200 for assembling the double-sided assembly 400. Additionally, a light reflecting assembly 500 is included, the light reflecting assembly 500 including a light reflecting panel 510 and a fixture. The reflective panel 510 is disposed under the double-sided assembly 400 along the arrangement direction of the pillars 100, and the fixing member fixes the reflective panel 510 to the base 600.
This embodiment sets up the below at two-sided subassembly 400 through the direction of arranging with reflection of light panel 510 along stand 100, and with base plane 600 fixed connection, on the one hand, set up reflection of light panel 510 and can effectively promote the ground reflectivity near base plane 600, with the back of sunshine reflection to two-sided subassembly 400, improved the photoelectric conversion efficiency of two-sided subassembly 400, increased the generating capacity at two-sided subassembly 400 back. On the other hand, the mounting point of the light reflecting panel 510 is on the base surface 600, so that the installation is convenient, the applicability is strong, the ground type does not need to be changed, and the later maintenance is facilitated.
In actual production, the base 600 may be a floor, a base, etc., as the case may be.
Referring to fig. 2, the cross-section of the reflective panel 510 may be a symmetrical inverted "V" shape along the arrangement direction of the pillars 100, considering the relationship between the incident angle and the reflection angle when the light is reflected. Compared with a single plane or inclined plane, the inverted V-shaped arrangement can reflect more sunlight, and the reflected sunlight can be more intensively reflected to the back of the double-sided assembly 400, thereby effectively improving the photoelectric conversion efficiency of the double-sided assembly 400. In addition, the inverted "V" shape sets up and is the triangle-shaped structure, and stability is higher, can also improve the stable form that is suitable for the photovoltaic support of two-sided subassembly 400.
This embodiment is only an optimal solution, and in practical production, the cross section of the reflective panel 510 may also be in a symmetrical arch shape along the arrangement direction of the pillars 100, and the like, and any configuration is within the protection scope of this patent.
Specifically, referring to fig. 1, 2 and 3, the reflective panel 510 is formed by two reflective plates 513 symmetrically overlapped, and the two reflective plates 513 are disposed at an angle. Based on in actual production, but reflective panel 510 integrated into one piece, but the installation of integrated into one piece's reflective panel 510 is not very convenient, and when later maintenance carried out the dismouting, need demolish mounted purlin 300, two-sided subassembly 400 etc. earlier, consume very big manpower and materials. Therefore, the light reflecting panel 510 is formed by symmetrically overlapping the two light reflecting plates 513, so that field layout and installation are facilitated, later maintenance is convenient, and time and cost are saved.
It should be noted that, in this embodiment, the angle formed between the two reflective plates 513 is not particularly limited, and can be flexibly adjusted according to the field environment, climate, and the like, for example, the angle formed between the two reflective plates 513 may be an acute angle, and it may also be a right angle or an obtuse angle, which are within the protection scope of this patent. Further, the angle between the two light reflecting plates 513 can be adjusted to any required angle value according to actual requirements, so that the application range of the light reflecting plate can be expanded.
In actual production, an included angle formed between the two reflective plates 513 is generally 90 ° to 180 °, which can be specifically adjusted according to actual conditions (such as terrain and reflective requirements), and if the included angle is too small, sunlight is easily reflected out of an area where the back surface of the double-sided assembly 400 can absorb light energy, so that power generation benefits are reduced, and the stability is slightly worse than that of a large-angle included angle.
Specifically, referring to fig. 2 to 4, the two side edges of each light reflecting plate 513 are respectively provided with a first edge strip 511 and a second edge strip 512.

In one embodiment, referring to fig. 2 and 4, the first edge strip 511 and the second edge 512 are integrally formed with the light reflecting plate 513, and have a simple structure, easy assembly and low cost. In actual production, the first edge strip 511 and the second edge strip 512 can be separate parts, but they still need to be fixed with the reflector 513 at a later stage, and the cost is increased and the assembly time is long.
In one embodiment, referring to fig. 2 and 3, the fixing member for fixing the reflector 513 to the base 600 may include a plurality of connecting bolts 521 and a plurality of anchor bolts 522. The first side strips 511 are provided with a plurality of first mounting holes along the length direction thereof, and when the two first side strips 511 are abutted and matched, the two first mounting holes at each opposite position are screwed and fixed through a connecting bolt 521, so as to lock the two first side strips 511 into a whole. Correspondingly, a plurality of second mounting holes are formed in the second edge strip 512 along the length direction of the second edge strip, and anchor bolts 522 are inserted into the second mounting holes and used for locking the second edge strip 512 to the base surface 600.
By adopting the connecting bolt 521 and the foundation bolt 522, the dismounting and the mounting can be realized by only screwing the connecting bolt 521 and the foundation bolt 522 to lock or loosen the connecting bolt 521 and the foundation bolt 522 without special tools, and the labor cost is greatly reduced.
In addition, the foundation bolt 522 is adopted to adapt to various terrains, the ground type does not need to be changed, and the adaptability is strong and the stability is good.
In one embodiment, referring to fig. 2 and 3, the position of the light-reflecting panel 510 corresponding to each of the pillars 100 is provided with an accommodating opening 530 adapted to the transverse section of the pillar 100, so as to facilitate assembly, and to some extent, the light-reflecting panel can limit the shaking of the pillar 100, so that the light-reflecting panel is more stable.
Preferably, the light reflecting panel 510 is made of light-colored nylon plate. Based on nylon board mechanical strength is high, and toughness is good, has higher tensile, compressive strength, and the surface is difficult to pile up a lot of advantages such as dust, adopts two reflection of light panels 510 of its preparation to be the angle setting, enables the automatic landing of dust, realizes the automatically cleaning, and later stage cleaning and maintenance are very laborsaving. In addition, select for use light color nylon board can reflect more sunshine to effectively promote ground reflectivity, increase the back generating capacity of two-sided subassembly 400.
The photovoltaic support suitable for the double-sided assembly is simple in structure, strong in stability, capable of adapting to various terrains, capable of effectively improving the ground reflectivity and high in power generation benefit.
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
