Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module conveying technology, and in particular relates to a buffered back-contact photovoltaic module. Background Technology

[0002] Back-contact photovoltaic modules, such as IBC (interlocked back contact cells), have positive and negative metal electrodes arranged in an interdigital pattern on the back surface of the cell, with the PN junction also located on the back of the cell. Since there are no metal electrodes blocking light on the front, they can achieve higher short-circuit current and conversion efficiency, making them one of the photovoltaic cells with the highest conversion efficiency currently available.

[0003] When transporting existing back-contact photovoltaic (PV) modules, the PV modules need to be placed in a transport box before being transported by vehicle. Since the PV modules are pre-placed on support frames, when the vehicle travels on bumpy roads, the PV modules inside the transport box are prone to shaking. At this time, the support frames will collide with the inner wall of the transport box, resulting in damage to the PV modules. This problem urgently needs to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a buffered back-contact photovoltaic module to solve the problem that conventional photovoltaic modules in the prior art are damaged by collisions during transportation.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A buffered back-contact photovoltaic module includes a photovoltaic module body, a frame, and a buffer portion, wherein:

[0007] The photovoltaic module body includes a plurality of photovoltaic panels spaced apart, with adjacent photovoltaic panels connected by a mounting plate. The frame is fitted around the plurality of photovoltaic panels and is configured to fix the plurality of photovoltaic panels within a fixed area enclosed by the frame. Each side of the frame is provided with at least one buffer portion.

[0008] The buffer section includes a first mounting platform, a first buffer spring, and a second mounting platform. The first mounting platform is detachably mounted on the corresponding side of the frame via a disassembly component. The first end of the first buffer spring is mounted on the first mounting platform and extends toward the support frame. The second mounting platform is mounted on the second end of the first buffer spring and abuts against a predetermined position on the support frame.

[0009] Furthermore, the buffer section also includes a guide rod, the first end of which is mounted on the first mounting platform, and the second end of which passes through the second mounting platform.

[0010] Furthermore, both sides of the mounting plate are connected to the photovoltaic panels through buffer units, and two adjacent photovoltaic panels are buffered to the mounting plate through the buffer units.

[0011] Furthermore, the buffer unit includes a second buffer spring, a first connecting plate, and a second connecting plate. The first connecting plate is vertically installed at the bottom of the mounting plate, and the second connecting plate is vertically installed at the bottom of the photovoltaic panel near the mounting plate. The two ends of the second buffer spring are respectively connected to the first connecting plate and the second connecting plate.

[0012] Furthermore, a displacement sensor is provided on the first mounting platform, and the displacement sensor is configured to detect the distance between the first mounting platform and the second mounting platform.

[0013] Furthermore, the support frame is provided with a limiting component, which includes two limiting baffles. The two limiting baffles are respectively disposed on both sides of the frame in the horizontal direction, and the limiting baffles are configured to limit the horizontal movement of the frame.

[0014] Furthermore, each side of the frame is provided with four sets of buffer sections.

[0015] Compared with existing technologies, the beneficial effects of the buffered back-contact photovoltaic module are as follows:

[0016] 1) By providing buffer parts on each side of the frame, the first end of the first buffer spring is mounted on the first mounting platform and extends toward the support frame, and the second mounting platform is mounted on the second end of the first buffer spring and abuts against the preset position of the support frame, the phenomenon of hard contact between the support frame and the frame is avoided when transporting photovoltaic modules, effectively preventing the support frame from colliding with the inside of the transport box and being damaged, thereby providing buffer force for the photovoltaic modules during transport and improving the safety of the photovoltaic modules during transport.

[0017] 2) By setting two limiting baffles, which are respectively set on both sides of the frame along the horizontal direction, the limiting baffles limit the horizontal movement of the frame, thereby further improving the delivery stability of the photovoltaic module. Attached Figure Description

[0024] Please see Figures 1 to 3As shown, in this embodiment, a buffered back-contact photovoltaic module includes a photovoltaic module body 10, a frame 20, and a buffer portion 30. The photovoltaic module body 10 includes a plurality of photovoltaic panels 11 spaced apart. Adjacent photovoltaic panels 11 are connected by a mounting plate 12. The frame 20 is sleeved around the plurality of photovoltaic panels 11. The frame 20 is configured to fix the plurality of photovoltaic panels 11 within a fixed area enclosed by the frame 20. At least one buffer portion 30 is provided on each side of the frame 20. The buffer portion 30 includes a first mounting platform 31, a first buffer spring 32, and a second mounting platform 33. The first mounting platform 31 is detachably mounted on the corresponding side of the frame 20 by means of a disassembly and assembly component. The first end of the first buffer spring 32 is mounted on the first mounting platform 31 and extends toward the support frame 40. The second mounting platform 33 is mounted on the second end of the first buffer spring 32 and abuts against a preset position on the support frame 40.

[0025] Specifically, the support frame 40 is also equipped with Bernoulli suction cups 41 on both sides near the frame 20. When transporting photovoltaic modules, the Bernoulli suction cups 41 on both sides adhere to the two sides of the frame 20.

[0026] It should be noted that the Bernoulli suction cup 41 proposed in this application embodiment is based on the implementation of the Bernoulli effect. According to Bernoulli's principle, when the suction cups on both sides are working, a pressure difference will be generated on the side of the frame 20 that is close to the suction cup and the side that is far away from the suction cup, thereby forming a thrust on the side of the frame 20 that is far away from the suction cup, thus maintaining stable placement.

[0027] As can be seen, by providing buffer portions 30 on each side of the frame 20, the first end of the first buffer spring 32 is mounted on the first mounting platform 31 and extends toward the support frame 40, and the second mounting platform 33 is mounted on the second end of the first buffer spring 32 and abuts against the support frame 40 at a preset position, the phenomenon of hard contact between the support frame 40 and the frame 20 is avoided when transporting photovoltaic modules, effectively preventing the support frame 40 from colliding with the inside of the transport box and being damaged, thereby providing buffering force for the photovoltaic modules during transport and improving the safety of the photovoltaic modules during transport.

[0028] In one embodiment, the buffer part 30 also includes a guide rod 34, the first end of which is mounted on the first mounting platform 31, and the second end of which passes through the second mounting platform 33.

[0029] In one implementation, both sides of the mounting plate 12 are connected to the photovoltaic panel 11 through the buffer unit 50, and two adjacent photovoltaic panels 11 are buffered to the mounting plate 12 through the buffer unit 50.

[0030] In one embodiment, the buffer unit 50 includes a second buffer spring 51, a first connecting plate 52, and a second connecting plate 53. The first connecting plate 52 is vertically installed at the bottom of the mounting plate 12, and the second connecting plate 53 is vertically installed at the bottom of the photovoltaic panel 11 near the mounting plate 12. The two ends of the second buffer spring 51 are respectively connected to the first connecting plate 52 and the second connecting plate 53.

[0031] Specifically, the second buffer spring 51 is sleeved on the guide shaft 54, the first end of the guide shaft 54 ​​is mounted on the first connecting plate 52, and the second end of the guide shaft 54 ​​passes through the second connecting plate 53.

[0032] In one embodiment, a displacement sensor 60 is provided on the first mounting platform 31, and the displacement sensor 60 is configured to detect the distance between the first mounting platform 31 and the second mounting platform 33.

[0033] In one embodiment, a limiting component is provided on the support frame 40. The limiting component includes two limiting baffles 42, which are respectively disposed on both sides of the frame 20 in the horizontal direction. The limiting baffles 42 are configured to limit the movement of the frame 20 in the horizontal direction.

[0034] As can be seen, by setting two limiting baffles 42, which are respectively set on both sides of the frame 20 along the horizontal direction, the limiting baffles 42 limit the horizontal movement of the frame 20, thereby further improving the delivery stability of the photovoltaic module.

[0035] Specifically, a sponge is provided on the support frame 40 at the same height as the frame 20. The sponge is configured to prevent hard contact between the frame 20 and the support frame 40 during transport.

[0036] In one implementation, four sets of buffer sections 30 are provided on each side of the frame 20.

[0037] When the aforementioned buffered back-contact photovoltaic modules are in operation: multiple buffered back-contact photovoltaic modules are stacked on the support frame 40 by manual labor or a robotic arm. The second mounting platform 33 abuts against the preset position of the support frame 40. During the transportation of the transport box by the vehicle, the first buffer spring 32 located on the same side provides buffering force to the frame 20. At the same time, through the cooperation of the second buffer spring 51, the first connecting plate 52 and the second connecting plate 53, two adjacent photovoltaic panels 11 are buffered connected to the mounting plate 12, providing buffering force between the two adjacent photovoltaic panels 11, thereby improving the safety and stability of the photovoltaic panels 11 during transportation.

[0038] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
