Description

Technical Field

[0001] This application relates to the field of wall-mounted equipment support technology, and in particular to a rack. Background Technology

[0002] With the explosive growth of the global photovoltaic industry, the demand for residential and commercial distributed photovoltaic systems has surged, driving the need for miniaturization and scenario adaptability of photovoltaic equipment. In urban and residential settings, ground space is prioritized, and wall-mounted designs save installation area, making them particularly suitable for rooftop photovoltaics and garage charging stations. Therefore, some photovoltaic equipment is installed using a wall-mounted structure. However, in the product transportation process, wall-mounted inverters are usually transported separately to their destination. At the destination, professional personnel are required to mount the inverters on fixed objects such as walls and pillars, resulting in high labor installation costs. Utility Model Content

[0003] In view of the above, it is necessary to provide a rack to address the aforementioned deficiencies.

[0004] This application provides a frame for mounting photovoltaic equipment, comprising: a main frame; a mounting frame connected to the main frame, the top surface of the mounting frame having a locking hole for mounting the photovoltaic equipment, and the locking hole for fastening the hooks of the photovoltaic equipment; an overlapping frame detachably connected to the main frame, the overlapping frame being located above the locking hole of the mounting frame, the overlapping frame being used to fit onto the hooks and position the hooks; and a load-bearing frame connected to the main frame and located below the mounting frame, the load-bearing frame being used to support the photovoltaic equipment and limit the lower part of the photovoltaic equipment.

[0005] In some embodiments, the lap frame is provided with a positioning groove, the opening of which faces the hanger, and the positioning groove is used to accommodate hooks.

[0006] In some embodiments, a first buffer pad is provided in the positioning groove, which is used to absorb the vibration kinetic energy of the hook.

[0007] In some embodiments, the bottom of the photovoltaic device is provided with a support leg; the load-bearing frame is provided with a limiting groove, the opening of the limiting groove is facing the mounting frame, the limiting groove is used to receive the support leg and limit the support leg along a first direction, the first direction having an angle with the vertical direction.

[0008] In some embodiments, a baffle portion is formed at the end of the limiting groove away from the mounting frame of the load-bearing frame. The baffle portion is used to limit the support leg in a second direction, and there is an angle between the first direction and the second direction.

[0009] In some embodiments, a second buffer pad is provided in the limiting groove, which is used to absorb the vibration kinetic energy of the support leg.

[0010] In some embodiments, the mounting frame includes mounting brackets and mounting reinforcements. There are multiple mounting brackets, which are spaced apart along a first direction. The top end of the mounting bracket is provided with a locking hole. The multiple mounting brackets are respectively connected to the main frame. The mounting reinforcements are connected between the top ends of two adjacent mounting brackets. There is an angle between the first direction and the vertical direction.

[0011] In some embodiments, the main frame includes columns and multiple fixed beams, the multiple fixed beams being distributed at intervals along the vertical direction and each of the multiple fixed beams being connected to the columns; the fixed beams are provided with multiple through holes for mounting frames, lap frames or load-bearing frames to be installed and fixed to the fixed beams.

[0012] In some embodiments, the column is provided with a plurality of adjustment holes along the vertical direction, and the fixing beam is detachably connected to at least one of the plurality of adjustment holes.

[0016] The rack provided in this application allows for the initial installation of the mounting frame and load-bearing frame onto the main frame before transporting or testing photovoltaic (PV) equipment. The PV equipment is then placed on the load-bearing frame, and its hooks are engaged with the mounting frame's locking holes. An extension frame is then installed onto the mounting frame, fitting over the hooks and positioning them on the mounting frame. In this way, the lower part of the PV equipment is supported and restrained by the load-bearing frame, while the upper part is positioned by the mounting frame and extension frame, ensuring stable installation on the rack and preventing the PV equipment from detaching during transport or testing. During product transportation, users can choose to have the PV equipment pre-mounted on the rack at the manufacturer's location or in areas with lower labor costs.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0026] In the description of the embodiments in this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0027] In related technologies, some photovoltaic equipment is installed using a wall-mounted structure. Taking inverters as an example, inverters typically have hooks on the back, which allow them to be hung on fixed objects such as walls and pillars during normal use. Currently, inverters are usually transported separately to their destination, requiring users to hire professionals to wall-mount them on fixed objects like walls and pillars, resulting in high labor installation costs.

[0028] To address the aforementioned issues, this application provides a rack capable of mounting photovoltaic (PV) equipment (such as inverters). During product transportation, users can choose to have the PV equipment pre-mounted on the rack at the manufacturer's location or in areas with lower labor costs. The rack and PV equipment can then be transported together to the destination for direct use. This eliminates the need for separately hiring professionals to install the PV equipment on the wall, reducing labor costs and improving economic efficiency.

[0029] On the other hand, the original wall-mounted photovoltaic equipment was designed with only the requirements of load testing, drop testing or transportation simulation testing in mind, without taking into account the vibration of the photovoltaic equipment and frame during transportation. Therefore, it is uncertain whether the photovoltaic equipment can maintain good performance after being mounted and transported.

[0030] To address the aforementioned issues, this application provides a universal frame structure applicable to both transportation and testing scenarios. Before transporting the photovoltaic equipment, vibration simulation tests of the equipment's mounting and transport can be conducted. In the testing scenario, the frame can be used as a testing fixture. The photovoltaic equipment is first hung and assembled onto the frame, and then both the photovoltaic equipment and the frame are fixed together on a vibration testing platform. During vibration testing, the vibration testing platform induces vibrations in both the photovoltaic equipment and the frame to simulate the impact of vibrations on the photovoltaic equipment during long-distance transportation. Furthermore, based on the feedback results of the vibration test, the connection structure of the frame or the photovoltaic equipment can be optimized and improved to meet corresponding safety performance requirements.

[0031] In summary, this application provides a rack suitable for transporting or testing wall-mounted photovoltaic equipment, which reduces installation costs and ensures the safety performance of the equipment.

[0032] Figure 1 A schematic diagram of the frame and photovoltaic equipment provided in the first embodiment of this application. Figure 2 An exploded view of the rack and photovoltaic equipment provided in the first embodiment of this application. Figure 1 and Figure 2 The first embodiment of the rack is shown in both examples.

[0033] like Figure 1 and Figure 2 As shown, the frame 100 can be used to mount the photovoltaic device 200. The photovoltaic device 200 has a hook 201 on one side and supports 202 at its bottom. For example, the photovoltaic device 200 is an inverter. The front of the photovoltaic device 200 has an operation panel integrating a display screen, interactive buttons, and other functional modules. The back of the photovoltaic device 200 has two hooks 201, distributed on the upper part of the photovoltaic device 200 with a gap between them. One end of each hook 201 is fixed to the photovoltaic device 200, and the other end has a downward-extending hook-shaped portion, which can engage with other structures. The bottom surface of the photovoltaic device 200 has two supports 202.

[0034] It is understood that the directional descriptions used in this application, such as up, down, top, bottom, vertical, horizontal, etc., are based on the posture of the product in normal use and are intended to illustrate the orientation of the product, and are not a limitation on the structure of the product itself.

[0035] Figure 3 A schematic diagram of the frame's mounting bracket, hanging bracket, and load-bearing frame according to the first embodiment of this application.

[0036] Please refer to the following: Figure 3 In this embodiment, the frame 100 includes a main frame 10, a mounting frame 20, a connecting frame 30, and a load-bearing frame 40. The main frame 10 is the main framework of the frame 100, used to support the mounting frame 20, the connecting frame 30, and the load-bearing frame 40. The mounting frame 20, the connecting frame 30, and the load-bearing frame 40 cooperate to fix the photovoltaic device 200 and simultaneously limit the photovoltaic device 200 in the vertical direction, the first direction, and the second direction. The first direction and the second direction have an included angle, and both the first direction and the second direction have an included angle with the vertical direction. For example, in the illustration, the Z direction indicates the vertical direction, the X direction indicates the first direction, and the Y direction indicates the second direction.

[0037] In this embodiment, the mounting frame 20 is connected to the main frame 10, and a locking hole 21 is provided on the top surface of the mounting frame 20. The mounting frame 20 is used for hanging the photovoltaic device 200, and the locking hole 21 is used for fastening the hook 201 of the photovoltaic device 200. The overlapping frame 30 is detachably connected to the main frame 10, and the overlapping frame 30 is located above the locking hole 21 of the mounting frame 20. The overlapping frame 30 is used to fit over the hook 201 to position the hook 201. The load-bearing frame 40 is connected to the main frame 10 and is located below the mounting frame 20. The load-bearing frame 40 is used to support the photovoltaic device 200 and limit the lower part of the photovoltaic device 200.

[0038] When the photovoltaic equipment 200 needs to be transported or tested, the mounting frame 20 and the load-bearing frame 40 can be installed on the main frame 10 respectively. Then, the photovoltaic equipment 200 is placed on the load-bearing frame 40, and the hooks 201 of the photovoltaic equipment 200 are fastened to the locking holes 21 of the mounting frame 20. Next, the overlapping frame 30 is installed on the mounting frame 20, so that the overlapping frame 30 is fitted onto the hooks 201, and the hooks 201 are positioned on the mounting frame 20. In this way, the lower part of the photovoltaic equipment 200 is supported and limited by the load-bearing frame 40, and the upper part of the photovoltaic equipment 200 is positioned by the mounting frame 20 and the overlapping frame 30, so as to stably install the photovoltaic equipment 200 on the frame 100 and prevent the photovoltaic equipment 200 from falling off the frame 100 during transportation or testing.

[0039] It is worth noting that the rack 100 in this embodiment is a frame structure that is applicable to both transportation and testing scenarios.

[0040] In a transportation scenario, the shipper can mount the photovoltaic equipment 200 onto the rack 100, and then transport the photovoltaic equipment 200 and the rack 100 together to the destination, thus achieving mounted transportation of the photovoltaic equipment 200. In this way, users can directly put the photovoltaic equipment 200 and the rack 100 into the work environment, reducing manual installation costs.

[0041] Figure 4 This is a schematic diagram of the rack provided in this application in a test scenario.

[0042] Please refer to the following: Figure 4 In the testing scenario, the photovoltaic device 200 can be mounted on the rack 100, and then the photovoltaic device 200 and the rack 100 can be fixed together on the test platform 300 for vibration testing to simulate the impact of vibration on the photovoltaic device 200 during long-distance transportation. The feedback results of the vibration test can be used to optimize and improve the connection structure of the rack 100 or the photovoltaic device 200 to meet the corresponding safety performance requirements.

[0043] Figure 5 A schematic diagram of the main frame of the rack provided in the first embodiment of this application.

[0044] Please refer to the following: Figure 5 In some embodiments, the main frame 10 is assembled from welded sheet metal square tubes to meet the corresponding support strength requirements. Specifically, the main frame 10 includes columns 11 and fixed beams 12, wherein there are multiple fixed beams 12, which are distributed at intervals along the vertical direction and are respectively connected to the columns 11. The fixed beams 12 are provided with multiple through holes 13 for mounting the hanger 20, the overlapping frame 30, or the load-bearing frame 40 to the fixed beams 12.

[0045] It is understandable that the mounting frame 20, the overlapping frame 30, and the load-bearing frame 40 can all be fixed on one or more fixed beams 12. That is, the mounting frame 20, the overlapping frame 30, and the load-bearing frame 40 can use the same installation components, thereby reducing production costs and simplifying the assembly process.

[0046] For example, there are multiple columns 11, which are spaced apart along a first direction, and each column 11 extends vertically. The main frame 10 has multiple adjustment holes 18 along the vertical direction, and the fixing beam 12 is detachably connected to at least one of the adjustment holes 18. The adjustment holes 18 are oblong holes that penetrate opposite sides of the column 11.

[0047] For example, a top beam 15 and a bottom beam 16 are provided between two adjacent columns 11, arranged vertically. Both the top beam 15 and the bottom beam 16 extend along a first direction. The two ends of the top beam 15 are bolted to the two columns 11, and the two ends of the bottom beam 16 are also bolted to the two columns 11, thus maintaining a fixed connection between the two columns 11. A base frame 50 is also provided at the lower end of each column 11, extending along a second direction and bolted to the column 11. The main frame 10 can be stably placed on a flat surface such as the ground or a test platform 300 using the base frame 50.

[0048] For example, multiple fixed beams 12 are located between the top beam 15 and the bottom beam 16. Each fixed beam 12 extends along a first direction, and both ends of the fixed beam 12 are detachably connected to two columns 11. Specifically, each end of the fixed beam 12 is provided with a first bolt 14, and a through-hole structure is provided for the first bolt 14 to pass through. Both ends of the fixed beam 12 are bolted and fixed to the adjustment holes 18 of the columns 11 by the first bolts 14, so that the fixed beam 12 and the columns 11 are detachably connected.

[0049] In practical applications, the fixed beam 12 can be installed using the appropriate adjustment hole 18 according to actual needs (such as frame installation height, hanging height, etc.). When it is necessary to adjust the height of the fixed beam 12, the first bolt 14 at the end of the fixed beam 12 can be removed to disassemble the fixed beam 12 from the original adjustment hole 18. Then, the fixed beam 12 can be adjusted to a suitable height, and then the fixed beam 12 can be re-fixed to the corresponding adjustment hole 18 using the first bolt 14. In this way, the height of the fixed beam 12 can be quickly adjusted to adapt to different installation requirements.

[0050] For example, a plurality of through holes 13 are formed on the surface of the fixed beam 12. The plurality of through holes 13 are spaced apart along the length direction of the fixed beam 12. The through holes 13 can cooperate with the bolt structure to fix the structure attached to the bolt structure to the fixed beam 12. Among them, the frame such as the overlapping frame 30, the hanging frame 20 and the load-bearing frame 40 can be fixed to the through holes 13 by bolt structure, so as to adjust the distance between the overlapping frame 30, the hanging frame 20 and the load-bearing frame 40 according to the shape of the photovoltaic equipment 200, so as to adapt to the usage requirements of photovoltaic equipment 200 of different models and sizes.

[0051] It is understood that the number and height of the fixed beams 12 can be configured according to the installation requirements of the scaffolding, such as the overlapping frame 30, the hanging frame 20, and the load-bearing frame 40. In the example of this application, the number of fixed beams 12 is 5, defined from top to bottom as: fixed beam 12A, fixed beam 12B, fixed beam 12C, fixed beam 12D, and fixed beam 12E. Fixed beam 12A is used to install the overlapping frame 30, which is fixed to fixed beam 12A by the second bolt 31. Fixed beams 12B and 12C are used to install the hanging frame 20, which is fixed to fixed beams 12B and 12C by the third bolt 22. Fixed beams 12D and 12E are used to install the load-bearing frame 40, which is fixed to fixed beams 12D and 12E by the fourth bolt 41.

[0052] For example, the main frame 10 also includes multiple reinforcing beams 17, which are welded and fixed between the column 11, the bottom beam 16, and the base frame 50 to enhance the overall rigidity of the main frame 10, meet the corresponding support strength requirements, and reduce the impact of problems with the main frame 10 itself on the test results of the photovoltaic equipment 200 in the test scenario, effectively ensuring the reliability of the test results.

[0053] Please refer to the following: Figure 3In some embodiments, the mounting frame 20 includes mounting brackets 23 and mounting reinforcements 24. Multiple mounting brackets 23 are distributed at intervals along a first direction, and each mounting bracket 23 has a locking hole 21 at its top. A support piece 44 is provided at the top of each mounting bracket 23, and the locking hole 21 penetrates the support piece 44 vertically. Multiple mounting brackets 23 are respectively connected to the main frame 10, and the mounting reinforcements 24 are connected between the tops of two adjacent mounting brackets 23.

[0054] The number and position of the mounting brackets 23 correspond to the number and position of the hooks 201 on the photovoltaic device 200. In the example of this application, the number of mounting brackets 23 is 2, and the positions of the two mounting brackets 23 are directly below the positions of the two hooks 201 on the photovoltaic device 200. In this way, the two hooks 201 on the photovoltaic device 200 can be directly inserted into the slots 21 of the two mounting brackets 23 from top to bottom.

[0055] For example, the upper and lower ends of the mounting bracket 23 are respectively bolted to the corresponding fixed beam 12 by the third bolt 22. The mounting reinforcement 24 extends along the first direction, is located on the upper part of the mounting bracket 23, and its two ends are respectively bolted to the two mounting brackets 23.

[0056] In this way, the photovoltaic device 200 can be hung on the top of the mounting component 23 via the hook 201, while the mounting reinforcement 24 provides structural reinforcement to the top of the mounting component 23 to improve the support capacity of the mounting component 23 and enhance the mounting stability of the photovoltaic device 200.

[0057] In some embodiments, the number and position of the mounting brackets 30 correspond to the number and position of the hooks 201 on the photovoltaic device 200. In the example of this application, the number of mounting brackets 30 is 2, and the positions of the two mounting brackets 30 are respectively located directly above the two mounting components 23.

[0058] For example, the lap frame 30 is provided with a positioning groove 32, the opening of the positioning groove 32 is positioned facing the hanger 20, and the positioning groove 32 is used to receive the hook 201. When the hook 201 is received in the positioning groove 32, the positioning groove 32 limits the hook 201 in the vertical direction and the first direction respectively.

[0059] For example, a connecting piece 33 is provided on one side of the overlapping frame 30. The connecting piece 33 has a through hole structure for the second bolt 31 to pass through. The connecting piece 33 is bolted and fixed to the fixed beam 12 by the second bolt 31, so that the overlapping frame 30 can be detachably connected to the fixed beam 12.

[0060] With the two hooks 201 of the photovoltaic device 200 respectively mounted on the mounting bracket 23, the overlapping bracket 30 can be sleeved onto the hooks 201 from top to bottom, so that the hooks 201 are received in the positioning groove 32, and the positioning groove 32 limits the hooks 201. Then, the overlapping bracket 30 is installed and fixed by the second bolt 31. It can be understood that by providing the mounting function for the hooks 201 through the mounting bracket 23, and cooperating with the overlapping bracket 30 to limit the hooks 201, the hooks 201 can be prevented from dislodging from the locking hole 21 of the mounting bracket 23, ensuring that the upper part of the photovoltaic device 200 is stably installed on the frame 100.

[0061] In some embodiments, a first buffer pad 34 is provided in the positioning groove 32, which is used to absorb the vibration kinetic energy of the hook 201. Exemplarily, the first buffer pad 34 may be made of a flexible material such as rubber. The first buffer pad 34 is bonded and fixed to the groove wall of the positioning groove 32, and when the hook 201 is received in the positioning groove 32, the first buffer pad 34 wraps tightly against the side wall of the hook 201.

[0062] It is understandable that during transportation, vibrations will occur between the photovoltaic equipment 200 and the frame 100, and some of the vibrations can be transmitted to the first buffer pad 34 through the hook 201. The first buffer pad 34 absorbs the kinetic energy of the vibration and achieves the effect of buffering and shock absorption.

[0063] In some embodiments, the number and position of the support frame 40 correspond to the number and position of the support leg 202 on the photovoltaic device 200. In the example of this application, the number of support frames 40 is 2, and the two support frames 40 are located directly below the two mounting brackets 23.

[0064] For example, the load-bearing frame 40 is provided with a limiting groove 42, the opening of which faces the mounting frame 20. The limiting groove 42 is used to receive the support leg 202 and limit the support leg 202 in a first direction. Furthermore, a baffle portion 43 is formed at the end of the limiting groove 42 away from the mounting frame 20, and the baffle portion 43 is used to limit the support leg 202 in a second direction.

[0065] When the load-bearing frame 40 is installed on the fixed beam 12, the opening of the limiting groove 42 is set upwards, and the support leg 202 of the photovoltaic device 200 can be inserted into the limiting groove 42 from top to bottom. Moreover, when the support leg 202 of the photovoltaic device 200 is received in the corresponding limiting groove 42, the load-bearing frame 40 supports the support leg 202 and the photovoltaic device 200, while the limiting groove 42 limits the support leg 202 and the photovoltaic device 200 in the first direction and the second direction respectively.

[0066] For example, a support plate 44 is provided on one side of the load-bearing frame 40. The support plate 44 extends vertically and has a through hole for a fourth bolt 41 to pass through. The support plate 44 is bolted to the fixed beam 12 by the fourth bolt 41, so that the load-bearing frame 40 is detachably connected to the fixed beam 12. A reinforcing rib 45 is also provided between the load-bearing frame 40 and the support plate 44. The reinforcing rib 45 is inclined relative to the vertical direction. One end of the reinforcing rib 45 is fixed to the load-bearing frame 40, and the other end of the reinforcing rib 45 is fixed to the support plate 44 to enhance the support strength of the load-bearing frame 40 for the support legs 202 and the photovoltaic equipment 200.

[0067] In some embodiments, a second buffer pad 46 is provided within the limiting groove 42, the second buffer pad 46 being used to absorb the vibrational kinetic energy of the support leg 202. Exemplarily, the second buffer pad 46 may be made of a flexible material such as rubber. The second buffer pad 46 is bonded and fixed to the groove wall of the limiting groove 42, and when the hook 201 is received within the limiting groove 42, the second buffer pad 46 wraps tightly against the side wall of the support leg 202.

[0068] It is understandable that during transportation, vibrations will occur between the photovoltaic equipment 200 and the frame 100, and some of the vibrations can be transmitted to the second buffer pad 46 through the hook 201. The second buffer pad 46 absorbs the kinetic energy of the vibration and achieves the effect of buffering and shock absorption.

[0069] It is worth noting that, in this embodiment, the first buffer pad 34 and the second buffer pad 46 can absorb vibration energy at the hook 201 and the support leg 202 of the photovoltaic device 200, respectively, significantly reducing the vibration amplitude of the photovoltaic device 200 during transportation, avoiding structural fatigue damage, and ensuring the safety performance of the photovoltaic device 200. Furthermore, the presence of the first buffer pad 34 and the second buffer pad 46 does not affect the static use of the photovoltaic device 200, and they can be removed during normal use.

[0070] Figure 6 A schematic diagram of the rack structure provided in the second embodiment of this application. Figure 7 An exploded view of the rack for the second embodiment provided in this application.

[0071] Combination Figures 1 to 4 Please refer to the following: Figure 6 and Figure 7 The second embodiment differs from the first embodiment in that: the bottom of the main frame 10 is provided with a mounting position 51, which is used for fixing the roller 52 or the positioning mechanism. The positioning mechanism can be a threaded post 301 pre-set on the test platform 300 in the test scenario, or a positioning post 53 pre-set on the ground in the actual working scenario. This embodiment uses a test scenario as an example for explanation.

[0072] For example, the base frame 50 has a plurality of insertion holes along its length, and the plurality of insertion holes penetrate the base frame 50 vertically, forming mounting positions 51 at the insertion holes. In the example of this application, each base frame 50 has three mounting positions 51, which are located at both ends and the middle of the base frame 50, respectively.

[0073] For example, the roller 52 is a caster wheel, and a screw is provided on the top of the roller 52. The screw can pass through the insertion hole and be threaded into the first locking nut 54, so that the roller 52 is installed on the bottom of the main frame 10. By unscrewing the first locking nut 54 from the screw, the roller 52 can be removed from the mounting position 51.

[0074] For example, the test platform 300 is provided with a threaded post 301, which extends vertically. The threaded post 301 can pass through the insertion hole and engage with the second locking nut, so that the bottom of the main frame 10 is fixed to the threaded post 301. The base frame 50 can be disassembled from the threaded post 301 by unscrewing the second locking nut from the threaded post 301.

[0075] Understandably, before or after the formal vibration test, rollers 52 can be installed at the bottom of the main frame 10 to facilitate the transportation of the push frame 100. During the formal vibration test, the rollers 52 can be removed from the bottom of the main frame 10, and the main frame 10 can be fixed on the test platform 300 for vibration testing.

[0076] The second embodiment differs from the first embodiment in that a buffer member 56 is provided at the bottom of the main frame 10. For example, the buffer member 56 may be made of a flexible material such as rubber, and the material, thickness, and hardness of the buffer member 56 can be configured according to actual needs, such as testing conditions and transportation conditions. The buffer member 56 is bonded and fixed to the bottom surface of the base frame 50. When the frame 100 is fixed to the test platform 300, the buffer member 56 is positioned between the bottom of the main frame 10 and the test platform 300 to reduce the vibration energy directly transmitted from the test platform 300 to the frame 100 during vibration testing.

[0077] The second embodiment differs from the first embodiment in that: multiple main frames 10 are provided, symmetrically distributed among the multiple main frames 10, and connecting beams 60 are provided between the multiple main frames 10. For example, the number of main frames 10 is 2, the two main frames 10 are distributed at intervals in the second direction and are mirror-symmetrical, the two ends of the connecting beams 60 are fixedly connected to the two main frames 10 respectively, and the connecting beams 60 and the main frames 10 are structurally reinforced by diagonal tie beams 19.

[0078] Understandably, multiple main frames 10 can be mounted on mounting frames 20, overlapping frames 30, and load-bearing frames 40 via fixed beams 12, allowing for the simultaneous mounting of multiple photovoltaic devices 200, thus improving transportation and testing efficiency. Furthermore, the symmetrical arrangement of the multiple main frames 10 avoids vibration disturbances caused by cantilever beam structures during testing, improving the accuracy of test results.

[0079] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments described above should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
