[0002] A monocrystalline bifacial double-glass photovoltaic module is a photovoltaic structure that can absorb light energy on both sides to generate electricity. The front side receives natural sunlight, while the back side receives reflected and scattered light, thereby increasing the light-receiving area and thus increasing power generation.

[0003] When installing existing monocrystalline bifacial double-glass photovoltaic modules, the photovoltaic module is placed directly on the mounting bracket, the back of the photovoltaic module is supported by the bracket, and the two sides of the photovoltaic module are fixed by clamps connected to the mounting bracket to achieve fixed installation of the photovoltaic module.

[0004] However, this connection method results in a small connection area between the mounting bracket and the photovoltaic module, and lower support strength. In addition, the bracket on the back will block the back of the photovoltaic module, thereby affecting the light-receiving effect on the back and directly reducing the power generation efficiency. Utility Model Content

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-4 A mounting bracket for a monocrystalline bifacial double-glass photovoltaic module includes a support frame 1 and a mounting structure 2. The support frame 1 serves as an overall support base and allows for adjustment of the mounting angle of the mounting structure 2. The mounting structure 2 is mounted on the support frame 1 and can be detachably mounted with multiple photovoltaic modules. This allows for the fixing of the photovoltaic modules on the mounting bracket, avoiding shading of the back of the photovoltaic modules, ensuring the back light-gathering effect, and ensuring power generation efficiency.

[0019] The mounting structure 2 includes a mounting frame 21 and two locking plates 22. The mounting frame 21 can be a rectangular frame welded from aluminum alloy plates. The mounting frame 21 is mounted on the support frame 1. Multiple photovoltaic modules are placed side by side along the length of the mounting frame 21. There can be up to 6 photovoltaic modules. The specific number can be set according to the size of the mounting frame 21, the size of the photovoltaic modules, and the spacing between adjacent photovoltaic modules. The contact area between the mounting frame 21 and the photovoltaic modules is smaller than the width of the photovoltaic module's frame. That is, the mounting frame 21 does not contact the crystal part of the photovoltaic module, avoiding shading the back of the photovoltaic module, thereby ensuring the back light-gathering effect. At the same time, it can increase the connection area between the mounting structure 2 and the photovoltaic modules and improve the connection strength. The locking plates 22 can be 2mm thick aluminum alloy plates, which are hinged to both ends of the mounting frame 21 by hinges. The free end of the locking plate 22 has a waist-shaped hole, which is screwed into the screw holes at both ends of the mounting frame 21 by stainless steel bolts to realize the detachable connection between the locking plate 22 and the mounting frame 21, thereby realizing the fixed installation of the photovoltaic modules on the mounting structure 2. A 3mm thick silicone pad with a Shore hardness of 60A can be attached to the side of the locking plate 22 facing the photovoltaic module. It can be pressed onto the frame of the photovoltaic module to avoid damage to the frame due to hard contact. At the same time, it can increase the friction between the locking plate 22 and the frame of the photovoltaic module, thereby improving the installation effect of the photovoltaic module.

[0020] In some embodiments, the mounting structure 2 further includes a plurality of partition blocks 23, which may be aluminum alloy blocks. The plurality of partition blocks 23 are arranged in two groups at equal intervals on the inner sidewalls at both ends of the mounting frame 21. Each group of partition blocks 23 is arranged between two photovoltaic modules to isolate adjacent photovoltaic modules and facilitate heat dissipation of photovoltaic modules. The specific length of the partition block 23 can be set according to the actual situation. In some embodiments, the mounting structure 2 further includes a plurality of sliding grooves 24, a sliding plate 25, and a positioning screw 26. The sliding grooves 24 may be T-shaped grooves formed on both ends of the mounting frame 21, and the plurality of sliding grooves 24 are distributed at equal intervals. The sliding plate 25 may be an L-shaped plate, one end of which can be welded and fixed to the partition block 23 and slide along the sliding groove 24, and the other end extends to the outside of the sliding groove 24 and is parallel to the end face of the mounting frame 21. The positioning screw 26 penetrates the sliding plate 25 vertically and is screwed into the sliding plate 25. The positioning screw 26 is pressed against the end face of the mounting frame 21, and after being tightened, the position of the sliding plate 25 can be locked by friction.

[0021] In some embodiments, the mounting structure 2 further includes a connecting hole 27, a locking hole group 28, and a locking screw 29. The connecting hole 27 can penetrate the center of the partition block 23. The locking hole group 28 is a group of through holes that are opened at the bottom of both ends of the locking plate 22 and the mounting frame 21. The locking screw 29 passes through the locking hole group 28 of the locking plate 22, the connecting hole 27, and the locking hole group 28 of the mounting frame 21 in sequence. A hexagonal nut is screwed to the bottom of the locking screw 29, which can realize the connection between the partition block 23 and the mounting frame 21 and the locking plate 22, thereby improving the connection strength between the mounting frame 21 and the locking plate 22. In some embodiments, the locking hole group 28 may include eight through holes with a diameter of 11 mm, arranged linearly along the length of the locking plate 22 or the mounting frame 21. The distance between the centers of two adjacent through holes may be 8 mm, which is smaller than the diameter of the through hole, so as to form a continuously adjustable locking position, which facilitates the adjustment of the position of the separator block 23 within the mounting frame 21.

[0022] In some embodiments, the support frame 1 includes multiple first support plates 11, multiple second support plates 12, multiple first support columns 13, and multiple second support columns 14. The first support plates 11 and 12 can both be made of Q235 steel plates, and their bottoms are fixed to the foundation using expansion bolts. The second support plates 12 correspond one-to-one with the first support plates 11, having the same structural specifications. The first support columns 13 can be seamless steel pipes, and their tops can be hinged to the end of the mounting frame 21 away from the ground via a rotating shaft and the rotating structure of the mounting base. The first support columns 13 and 11 are coaxially arranged. The second support columns 14 can be seamless steel pipes with the same specifications as the first support columns 13, and their tops can be hinged to the end of the mounting frame 21 near the ground via a rotating shaft and the rotating structure of the mounting base. The second support columns 14 and 12 are coaxially arranged. Through the combined support of multiple first support plates 11, multiple second support plates 12, multiple first support columns 13, and multiple second support columns 14, the installation structure 2 can be stably installed.

[0023] In some embodiments, the support frame 1 further includes multiple adjusting tubes 15, multiple adjusting holes 16, and adjusting screws 17. The adjusting tubes 15 can be seamless steel pipes, corresponding one-to-one with the first support plate 11 and coaxially welded. A corresponding first support column 13 is inserted into the top of the adjusting tube 15. The adjusting holes 16 can be through holes, extending laterally every 50mm along the height direction of the adjusting tube 15. The specific spacing can be set according to actual adjustment needs. The adjusting screws 17 pass through the corresponding through holes of the adjusting holes 16 and the first support column 13, and are screwed with adjusting nuts, which can lock the height of the first support column 13 on the adjusting tube 15, thereby adjusting the tilt angle of the photovoltaic module to adapt to the latitude and longitude of different regions.

[0024] In some embodiments, the support frame 1 further includes three connecting rods 18 and multiple diagonal braces 19. The connecting rods 18 can be steel pipes, and both ends can be welded to two partition blocks 23 to divide the mounting frame 21 into multiple placement areas to achieve partitioned placement of photovoltaic modules and improve the overall connection strength of the mounting structure 2. The diagonal braces 19 can be steel pipes, and the top can be connected to the side of the mounting frame 21 through a rotating shaft and the rotating structure of the mounting base. The bottom can be slidably connected to the adjusting pipe 15 through a sliding structure of a slider and a sliding groove. The slider can move vertically along the adjusting pipe 15, and the position of the slider in the sliding groove is fixed by a screw. The diagonal braces 19, the adjusting pipe 15, and the mounting frame 21 form a triangular stable structure, which can improve the overall stability of the support frame 1 and thus improve the stability of the photovoltaic module installation.

[0025] The specific working principle is as follows: The tilt angle of the photovoltaic modules is set according to the latitude and longitude of the installation area, thereby setting the installation spacing between the first support plate 11 and the second support plate 12. Multiple first support plates 11 and second support plates 12 are placed according to the set installation spacing and fixed to the foundation with expansion bolts to form stable support bases and ensure balanced force distribution.

[0026] First support column 13 and second support column 14 are respectively installed on first support plate 11 and second support plate 12 using bolts. According to the set angle, the insertion depth of first support column 13 in adjustment tube 15 is adjusted to select the corresponding height adjustment hole 16. Adjustment screw 17 is passed through adjustment hole and through hole on first support column 13. Adjustment nut is tightened to lock height. At this time, the tilt angle of mounting frame 21 matches solar altitude angle.

[0027] The top of the diagonal brace 19 is hinged to the connecting rod 18 or the mounting frame 21, and the bottom slides along the adjusting tube 15 to the corresponding position via a slider. The slider is locked by bolts, so that the diagonal brace 19, the first support column 13, the adjusting tube 15, the connecting rod 18 or the mounting frame 21 form a triangular stable structure.

[0028] Place the first photovoltaic module on the mounting frame 21, ensuring it is flush against the inner wall of one side of the frame. Loosen the adjacent positioning screw 26, and push the sliding plate 25 along the T-shaped groove 24 on the end face of the mounting frame 21. This causes the partition block 23 to move synchronously, allowing the adjacent partition block 23 to fit against the photovoltaic module frame. Tighten the positioning screw 26, using the friction between the positioning screw 26 and the end face of the mounting frame 21 to fix the sliding plate 25, ensuring the partition block 23 is in a stable position and preventing displacement due to vibration during module operation. Similarly, place other photovoltaic modules on the mounting frame 21. Flip the locking plates 22 at both ends of the mounting frame 21 so that they cover the top and bottom of the photovoltaic module frame. The 3mm thick silicone pad (Shore hardness 60A) on the inside of the locking plate 22 makes flexible contact with the frame to prevent hard pressure from causing the glass to break. The locking screw 29 passes through the locking hole group 28 of the locking plate 22, the connecting hole 27 of the partition block 23, and the locking hole group 28 of the mounting frame 21 in sequence. Tighten the nut to achieve a three-in-one fixation of "locking plate-partition block-mounting frame", and complete the installation of the photovoltaic module.
