Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation structures, and more specifically, to a self-clamping photovoltaic frame structure. Background Technique

[0002] A photovoltaic module is a photovoltaic cell combination device that is based on battery integration, has encapsulation and internal connection, and can provide direct current output independently. As the smallest effective power generation unit, the photovoltaic module undertakes the function of photoelectric conversion in a photovoltaic power station and is the core part of a photovoltaic power generation system.

[0003] The photovoltaic module is composed of a certain number of photovoltaic cells connected in series and parallel through wires and encapsulated. Please refer to Figure 1 , and mainly includes core components such as photovoltaic cells, interconnection bars, bus bars, photovoltaic glass, glue film, backplane, frame 2, junction box, etc.

[0004] The frame 2 of the photovoltaic serves as an important auxiliary material for the photovoltaic module, playing a role in encapsulating and providing strength support for the photovoltaic panel 1, ensuring that the module can withstand load impacts in an outdoor environment and meet the corresponding reliability requirements.

[0005] As shown in the appendix Figure 1 , the frame 2 of the existing photovoltaic module only has the functions of encapsulation and providing strength support, and external tooling fixtures such as pressing blocks and bolts are required to achieve fixation and connection with the crossbeam during the installation process at the power station system end.

[0006] Therefore, the installation process is cumbersome, time-consuming and laborious, and the spacing between the modules is large and the layout is not tight, resulting in waste of space and material costs.

[0007] In summary, how to reduce the installation process, the parts used in installation, and the use space is an urgent problem to be solved by those skilled in the art at present. Content of the Utility Model

[0008] In view of this, the purpose of the utility model is to provide a self-clamping photovoltaic frame structure, which can reduce the use of parts during the installation process of the photovoltaic panel through its own structure and improve the installation efficiency.

[0009] To achieve the above purpose, the utility model provides the following technical solutions:

[0010] A self-clamping photovoltaic frame structure, comprising:

[0011] A photovoltaic panel;

[0012] A frame for wrapping and fixing the photovoltaic panel;

[0013] A clamping mechanism arranged at the edge of the frame for fixedly connecting two adjacent photovoltaic panels;

[0014] The anti - detachment mechanism is used to limit the clamping mechanism during its use to prevent the clamping mechanism from failing.

[0015] Furthermore, in the present utility model, the clamping mechanism includes a clamping groove located on one side border in the width direction of the photovoltaic panel and a clamping buckle located on the other side border in the width direction of the photovoltaic panel. The clamping buckle and the clamping groove have an L - shaped cross - section with opposite directions.

[0016] When the clamping buckle and the clamping groove are cross - mated with each other, the two adjacent photovoltaic panels are fixedly connected.

[0017] Furthermore, in the present utility model, the anti - detachment mechanism includes:

[0018] Protrusions, at least one protrusion extending along the length direction of the photovoltaic panel is provided on the clamping buckle;

[0019] Grooves, the grooves cooperating with the protrusions are located on the clamping groove;

[0020] When the clamping buckle and the clamping groove are mated, the protrusions are placed in the grooves to achieve the anti - detachment effect.

[0021] Furthermore, in the present utility model, the protrusions are wedge - shaped structures for preventing the clamping buckle and the clamping groove from sliding along the height direction of the photovoltaic panel.

[0022] Furthermore, in the present utility model, an assembly gap is left between the clamping buckle and the clamping groove for the clamping buckle and the clamping groove to cooperate along the height direction of the photovoltaic panel.

[0023] Furthermore, in the present utility model, the clamping buckle and the clamping groove are in interference fit, and an anti - slip layer is provided on the contact surface between the clamping buckle and the clamping groove.

[0024] Furthermore, in the present utility model, it is characterized in that the anti - detachment mechanism further includes:

[0025] A baffle plate is provided on the border for restricting the movement of the clamping buckle and the clamping groove in the length direction of the photovoltaic panel.

[0026] Furthermore, in the present utility model, the baffle plate is slidably installed on the border.

[0027] Furthermore, in the present utility model, the baffle plate is rotatably installed on the border.

[0028] The self - clamping photovoltaic frame and photovoltaic module provided by the present utility model, during use, the frame wraps and fixes the photovoltaic panel, improving the strength of the photovoltaic panel during use. The clamping mechanism is arranged at the edge of the frame and is used to form a fixed connection between two adjacent photovoltaic panels, thereby realizing the mutual fixation of two adjacent photovoltaic panels, avoiding the need to fix all photovoltaic panels individually, greatly reducing the use of parts and the installation time when installing photovoltaic panels. It only needs to fix the photovoltaic panels at both ends of the photovoltaic matrix arranged side by side, which is beneficial to improving the installation efficiency. And by setting a self - clamping mechanism on the frame, the photovoltaic panels can be arranged closely, reducing the installation spacing and wasting less space. To prevent the clamping mechanism from failing, the anti - detachment mechanism is used to limit the clamping mechanism during use, and under the action of the anti - detachment mechanism, the fixing firmness between two adjacent photovoltaic panels is further strengthened, enabling the photovoltaic modules to achieve effective interconnection with each other without relying on any external tooling, only using the self - body frame structure.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The core of the present invention is to provide a self - clamping photovoltaic frame structure, which can improve the installation efficiency and reduce space waste.

[0041] Please refer to Figures 2-7 , the embodiments of the present invention provide a self - clamping photovoltaic frame structure, including a photovoltaic panel 1, a frame 2, a clamping mechanism 3 and an anti - detachment mechanism 4. The frame 2 is used to wrap and fix the photovoltaic panel 1. The clamping mechanism 3 is arranged at the edge of the frame 2 and is used to form a fixed connection between two adjacent photovoltaic panels 1. The anti - detachment mechanism 4 is used to limit the clamping mechanism 3 during use to prevent the clamping mechanism 3 from failing.

[0042] During use, the frame 2 wraps and fixes the photovoltaic panel 1, improving the strength of the photovoltaic panel 1 during use. The clamping mechanism 3 is arranged at the edge of the frame 2 and is used to form a fixed connection between two adjacent photovoltaic panels 1. Thus, the adjacent two photovoltaic panels 1 can be fixed to each other, avoiding the need to fix all the photovoltaic panels 1 separately, greatly reducing the use and installation time of parts when installing the photovoltaic panels 1. Only the photovoltaic panels 1 at the head and tail of the photovoltaic matrix arranged side by side need to be fixed, which is beneficial to improving the installation efficiency. And by setting the self - clamping mechanism 3 on the frame 2, the photovoltaic panels 1 can be arranged closely, reducing the installation spacing and space waste. To prevent the clamping mechanism 3 from failing, the anti - detachment mechanism 4 is used to limit the clamping mechanism 3 during use. Under the action of the anti - detachment mechanism 4, the fixing firmness between two adjacent photovoltaic panels 1 is further enhanced, enabling the photovoltaic modules to achieve effective interconnection with each other only by using the self - body frame 2 structure without any external tooling.

[0043] It should be noted that the specific structure of the clamping mechanism 3 in the embodiments of the present invention is not limited. As long as it can complete the fixed connection of two adjacent photovoltaic panels 1 arranged side by side.

[0044] In addition, the specific structure of the anti - detachment mechanism 4 in the embodiments of the present utility model is not limited. As long as it can restrict the clamping mechanism 3 to prevent it from falling off during use.

[0045] In addition, the specific installation position of the clamping mechanism 3 in the embodiments of the present utility model is not limited. As long as it is arranged on the frame 2 and can fix two adjacent photovoltaic panels 1 arranged side by side.

[0046] Please refer to Figures 4-7 , in order to further adapt to the use environment in the embodiments of the present utility model, the clamping mechanism 3 includes a card slot 301 on one side of the frame 2 in the width direction of the photovoltaic panel 1 and a buckle 302 on the other side of the frame 2 in the width direction of the photovoltaic panel 1. The buckle 302 and the card slot 301 have an L - shaped cross - section with opposite directions. When the buckle 302 and the card slot 301 are cross - mated, the two adjacent photovoltaic panels 1 are fixedly connected. That is to say, by setting both the buckle 302 and the card slot 301 as L - shaped structures and making them cross - mate to achieve fixation. When they cross - mate, they can be inserted through the height direction of the photovoltaic panel 1 or through the length direction of the photovoltaic panel 1, which is beneficial for corresponding adjustment according to the use environment.

[0047] It should be noted that the L - shaped structure limitation of the buckle 302 and the card slot 301 in the embodiments of the present utility model is not fixed. In some embodiments, other structures capable of achieving clamping can be adopted, such as S - shaped, Z - shaped, or serrated structures.

[0048] Please refer to Figures 4-7 , in order to further improve the firmness of the clamping mechanism 3 during use, the anti - detachment mechanism 4 is provided to include a protrusion 402 and a groove 401. The protrusion 402 is at least one protrusion 402 extending along the length direction of the photovoltaic panel 1 and is arranged on the buckle 302, and the groove 401 is a groove 401 cooperating with the protrusion 402 and is located on the card slot 301. When the buckle 302 and the card slot 301 cooperate, the protrusion 402 is placed in the groove 401 to achieve the anti - detachment effect. That is to say, by using the protrusion 402 on the buckle 302 and the groove 401 on the card slot 301 to cooperate with each other, when the buckle 302 and the card slot 301 cooperate, the protrusion 402 and the groove 401 also cooperate, thereby realizing the fixation of the clamping mechanism 3, which is beneficial for improving the fixation firmness between the photovoltaic panels 1.

[0049] It should be noted that the specific number of the protrusion 402 and the groove 401 in the embodiments of the present utility model is not limited. In some embodiments, specific settings can be made according to the usage situation.

[0050] In addition, the frame material in the embodiments of the present utility model is not limited, and any material that can be integrally formed by extrusion or pultrusion is applicable.

[0051] Please continue to refer to Figure 4 and Figure 5 , in some embodiments, the protrusion 402 is a wedge-shaped structure for preventing the buckle 302 and the card slot 301 from sliding along the height direction of the photovoltaic panel 1. That is to say, the structure of the protrusion 402 is defined as a wedge-shaped structure, and its orientation is set to prevent the buckle 302 and the card slot 301 from sliding along the height direction of the photovoltaic panel 1. Specifically, the cross-section of the protrusion 402 is a right triangle, and the right-angle side coincides with the frame 2, and the hypotenuse faces the direction of the card slot 301, so as to achieve the purpose of preventing the buckle 302 and the card slot 301 from falling off during use.

[0052] It should be noted that the description of the protrusion 402 using a wedge-shaped structure in the embodiments of the present invention is not a limitation. In some embodiments, it can adopt other shapes to achieve the required limiting function.

[0053] Please continue to refer to Figure 5 , in some embodiments, there is an assembly gap 303 between the buckle 302 and the card slot 301 for the buckle 302 and the card slot 301 to cooperate along the height direction of the photovoltaic panel 1. That is to say, the assembly gap 303 is used for the reserved gap of the protrusion 402 when the buckle 302 and the card slot 301 cooperate, so that the protrusion 402 can smoothly enter the inside of the groove 401 to achieve the anti-detachment function. This method is used for the adjacent two photovoltaic panels 1 to be clamped and matched along the height direction, and the anti-detachment of the frame is simply and effectively formed through this method.

[0054] It should be noted that the width of the assembly gap 303 in the embodiments of the present invention is not specifically limited. In some embodiments, it can be designed and adjusted according to the widths of the buckle 302, the card slot 301 and the protrusion 402.

[0055] Please refer to Figure 6 and Figure 7 , in order to further reduce the gap after clamping and improve the stability after clamping, the buckle 302 and the card slot 301 are in interference fit, and an anti-slip layer is provided on the contact surface of the buckle 302 and the card slot 301. That is to say, the interference fit between the buckle 302 and the card slot 301 can avoid shaking after clamping and further improve the firmness of clamping. This cooperation method is fixed by inserting the buckle 302 and the card slot 301 along the length direction of the photovoltaic panel 1. Therefore, this method can appropriately reduce the assembly gap 303, which is beneficial to further reducing the assembly interval and can also avoid unnecessary shaking. The anti-slip layer provided on the contact surface of the buckle 302 and the card slot 301 can also further improve the firmness of the clamping mechanism 3.

[0056] It should be noted that the specific structure of the anti-slip layer is not limited in the embodiments of the present utility model. In some embodiments, it may adopt structures such as anti-slip patterns or anti-slip glue layers.

[0057] Please continue to refer to Figure 6 and Figure 7 , in some embodiments, it further includes a baffle 403, which is arranged on the frame 2 and used to limit the movement of the buckle 302 and the card slot 301 in the length direction of the photovoltaic panel 1. That is to say, by setting the baffle 403 to limit the length direction of two adjacent photovoltaic panels 1, it can be avoided that they are misaligned and displaced during use, and at the same time, the purpose of limiting the clamping mechanism 3 can be achieved.

[0058] It should be noted that in the embodiments of the present utility model, the insertion method of the buckle 302 and the card slot 301 in the length direction of the photovoltaic panel 1 is limited, and there are two baffles 403, which are respectively arranged on the frames 2 on both sides of the length direction of the photovoltaic panel 1, so as to achieve precise limitation of the photovoltaic panel 1, avoid the situation that the photovoltaic panel 1 slides or is displaced during use, and at the same time, this structure can increase the firmness between two adjacent photovoltaic panels 1.

[0059] Please continue to refer to Figure 6 , in some embodiments, the baffle 403 is slidably installed on the frame 2. That is to say, by slidably installing the baffle 403 on the frame 2, before the card slot 301 and the buckle 302 are not engaged, the baffle 403 slides to a position without a limiting function, and after the card slot 301 and the buckle 302 are engaged, the baffle 403 is slid to a position with a limiting function, so as to achieve the limitation of the photovoltaic module.

[0060] It should be noted that the sliding direction of the baffle 403 is not limited in the embodiments of the present utility model. In some embodiments, the baffle 403 can slide along the width direction of the photovoltaic panel 1.

[0061] In addition, whether the baffle 403 has a locking structure is not limited in the embodiments of the present utility model. In some embodiments, a locking structure can be set to lock the position of the baffle 403 after it is limited, so as to avoid its accidental movement.

[0062] In addition, the specific manner of the above-mentioned locking structure is not limited in the embodiments of the present utility model. In some embodiments, the locking mechanism can adopt the way of damping sliding of the baffle 403, or the way of using an elastic member to push the baffle 403 to apply pressure to the locking position, or other ways that can achieve the locking function.

[0063] Please continue to refer to Figure 7, in some embodiments, the baffle 403 is rotatably mounted on the frame 2. That is to say, for the specific replacement solution of the above embodiments, by rotating the two baffles 403 mounted on the frames 2 on both sides of the photovoltaic panel 1 in the length direction, the photovoltaic module is limited by rotating the baffle 403 during use. The rotating connection of the baffle 403 can adopt a damping method to fix the rotation angle of the baffle 403, or a stop pin can be set to limit its rotation angle.

[0064] That is to say, the key point of the embodiment of the present invention is: the photovoltaic panel 1 is wrapped and fixed by the frame 2 to improve the strength of the photovoltaic panel 1 during use. The clamping mechanism 3 is arranged at the edge of the frame 2 and is used to form a fixed connection between two adjacent photovoltaic panels 1, so that the two adjacent photovoltaic panels 1 can be fixed to each other, avoiding the need to fix all the photovoltaic panels 1 separately, greatly reducing the use and installation time of parts when installing the photovoltaic panels 1. It only needs to fix the photovoltaic panels 1 at both ends of the photovoltaic matrix arranged side by side, which is beneficial to improving the installation efficiency. And by setting the self-clamping mechanism 3 on the frame 2, the photovoltaic panels 1 can be arranged closely, reducing the installation spacing and saving space to prevent the clamping mechanism 3 from failing. The anti-disengagement mechanism 4 is used to limit the clamping mechanism 3 during use. Under the action of the anti-disengagement mechanism 4, the fixing firmness between two adjacent photovoltaic panels 1 is further strengthened, so that the photovoltaic modules do not need to rely on any external tooling and only use the self-frame 2 structure to achieve effective interconnection between each other.

[0065] In this specification, the various embodiments are described in a progressive manner. The key point of each embodiment is to describe the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0066] The above provides a detailed introduction to a self-clamping photovoltaic frame structure of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
