According to an embodiment of the present invention, referring to fig. 1 to 5, a linkage reflection mechanism is assembled under a double-sided photovoltaic module 600, and includes a reflection panel 100, a plurality of buffering members 200, and a plurality of adjusting members 300. The reflective panel 100 has a plurality of openings 110 for the posts 700 to pass through, and the buffer 200 is assembled in the openings 110 and abuts against the posts 700. The two ends of the adjusting member 300 are respectively hinged to the double-sided photovoltaic module 600 and the light reflecting panel 100, so that the light reflecting panel 100 is installed below the double-sided photovoltaic module 600. In the rotating process of the double-sided photovoltaic module 600, the light reflecting panel 100 rotates along with the double-sided photovoltaic module 600 through the adjusting piece 300, and the buffer piece 200 is used for enabling the light reflecting panel 100 to rotate stably.

This embodiment is through setting up regulating part 300, make two-sided photovoltaic module 600 at the pivoted in-process, reflection of light panel 100 can follow two-sided photovoltaic module 600 and rotate, compare in being fixed angle setting with reflection of light panel 100, reflection of light panel 100 follows two-sided photovoltaic module 600 and has rotated the east of still having adapted to the sun and has risen west, it can be according to the position of shining of sunshine, adjust reflection angle in real time, and then make the back of two-sided photovoltaic module 600 receive the best reflection of light all the time, real-time ground reflectivity and two-sided module's gain has been improved to a very big extent.

In addition, the reflective panel 100 is installed below the double-sided photovoltaic module 600 through the adjusting member 300, a special fixing frame is not needed, the ground type does not need to be changed, and the reflective panel is high in applicability and simple in structure.

When two-sided photovoltaic module 600 rotated to certain angle, there was certain space between reflective panel 100 and the stand 700, can lead to reflective panel 100 to rock if the strong wind appears, at this moment, install and play certain cushioning effect in reflective panel 100 in opening 110 and butt bolster 200 of stand 700, and then weaken rocking of reflective panel 100, avoid reflective panel 100 and stand 700's further collision, the life of reflective panel 100 with stand 700 has been increased, whole stability has still been improved simultaneously.

In actual production, the reflective panel 100 is preferably made of a light-colored nylon sheet. The nylon plate has high mechanical strength, good toughness and higher tensile strength and compressive strength, dust is not easy to accumulate on the surface, the dust can automatically slide off, self-cleaning is realized, and later cleaning and maintenance are very labor-saving. 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.

In one embodiment, referring to fig. 1, the peripheral edge of the opening 110 is not in contact with the pillar 700, and the distance between the opening 110 and the vertical axis of the bifacial photovoltaic module 600 is greater than the distance between the opening 110 and the parallel bifacial photovoltaic module 600, so that the opening 110 has enough space for the reflective panel 100 to rotate along with the bifacial photovoltaic module 600. If the space is too small, the light-reflecting panel 100 rotates to a certain angle along with the double-sided photovoltaic module 600 and then is blocked, so that the rotation of the double-sided photovoltaic module 600 is affected, and the double-sided photovoltaic module cannot work normally.

Preferably, referring to fig. 1 to 5, the buffer 200 includes two limit springs 210, and the two limit springs 210 are symmetrically assembled at two opposite ends of the pillar 700 and abut against two opposite side edges of the opening 110, respectively. It is worth noting that the connection direction of the two limiting springs 210 and the rotation axis of the double-sided photovoltaic module 600 are perpendicular to each other, so as to provide an acting force with opposite offset directions for the light reflecting panel 100, thereby realizing a buffering effect on the light reflecting panel 100, further weakening the shaking of the light reflecting panel 100, avoiding further collision between the light reflecting panel 100 and the upright column 700, prolonging the service life of the light reflecting panel 100 and the upright column 700, and simultaneously improving the overall stability.

In practical production, the buffer members 200 may also be rubber pads disposed on two opposite side edges of the opening portion 110, and the connection direction of the two rubber pads and the rotation axis of the double-sided photovoltaic module 600 are perpendicular to each other. In addition, can also further set up the rubber pad at stand 700 relevant position, further promote the effect of buffering.

Of course, the arrangement of the buffer 200 is not limited to this, and other arrangement methods are also possible, which are not described herein.

In a preferred embodiment, referring to fig. 1 and 4, a plurality of adjusters 300 are spaced along the rotational axis of the bifacial photovoltaic module 600. Each adjusting member 300 includes two piston rods 310, the two piston rods 310 are symmetrically disposed on two sides of the pillar 700 and connected to the double-sided photovoltaic module 600 and the light-reflecting panel 100, so as to adjust the swing amplitude of the light-reflecting panel 100, so that the light-reflecting panel 100 reflects light to the back of the double-sided photovoltaic module 600 in real time.

In actual production, the interval between regulating part 300 can change according to actual conditions, and the distance of every interval can be inconsistent, can set up wantonly, and the installation limitation is little.

Referring to fig. 1 to fig. 3, for example, when the double-sided photovoltaic module 600 starts to rotate, one end of the double-sided photovoltaic module 600 moves upward and the other end moves downward, the piston rod 310 drives the reflective panel 100 to rotate, and the reflective panel 100 still tends to keep a static state just before the start due to the influence of inertia during the rotation process. At this moment, because of the telescopic characteristic of piston rod 310, the piston rod 310 that is connected with the one end of two-sided photovoltaic module 600 upward movement can extend, and the piston rod 310 that is connected with the other end can contract to make reflective panel 100 rotate the in-process, can be certain contained angle with two-sided photovoltaic module 600 always, realize the self-regulation of reflective panel 100 angle, promote two-sided photovoltaic module 600's generated energy.

In addition, referring to fig. 3, the piston rod 310 is configured to prevent the reflective panel 100 from touching the ground during rotation, which may affect the life of the reflective panel 100. Because the reflective panel 100 is installed below the photovoltaic panel, the height from the ground is limited, and generally, in order to increase the sunlight that can be reflected by the reflective panel 100, the length of the reflective panel 100 in the direction perpendicular to the rotation axis of the bifacial photovoltaic module 600 is not too small. Therefore, when the angle of rotation of the double-sided photovoltaic module 600 is too large, the reflective panel 100 may touch the ground with a certain probability. At this moment, the piston rod 310 is scalable, and the piston rod 310 that two-sided photovoltaic module 600 one end is connected extends the longest, and other end piston rod 310 can contract to avoid one side that reflective panel 100 corresponds to touch ground, cause the damage, and the spacing spring 210 butt stand 700 of corresponding position prevents to cause the damage because of conflicting the extrusion between reflective panel 100 and the stand 700.

In actual production, the piston rod 310 may be replaced by a component having elasticity such as a rubber strip and a spring, and of course, it may also be a rod-shaped component such as a support rod that is not adjustable.

Specifically, referring to fig. 2, 3 and 5, the piston rod 310 may include a body portion 311 and a rod portion 312 slidably connected to the body portion 311, and the body portion 311 is hinged to the light reflecting panel 100 by one rotating connector 400, and the rod portion 312 is hinged to the back of the double-sided photovoltaic module 600 by another rotating connector 400.

Referring to fig. 5, the rotating connector 400 may specifically include a connecting portion 410 and two limiting portions 420 respectively disposed at two opposite sides of the connecting portion 410, the connecting portion 410 is used to connect the body portion 311 or the rod portion 312, and the limiting portions 420 are used to limit the movement of the body portion 311 or the rod portion 312 along the rotation axis direction of the double-sided photovoltaic module 600, so as to improve the linkage between the double-sided photovoltaic module 600 and the reflective panel 100. The connecting portion 410 and the two position-limiting portions 420 together form a movable slot 430 for the rotation of the body portion 311 or the rod portion 312.

Referring to fig. 1, the photovoltaic support provided by the utility model further includes a main beam 500, a double-sided photovoltaic module 600, a linkage reflection mechanism, a plurality of columns 700, and a plurality of purlins 800.
