Description

Technical Field

[0001] The present application relates to the technical field of solar power generation, and in particular to a photovoltaic system, a photovoltaic module and a frame thereof. Background Art

[0002] The new energy industry is an emerging industry that my country has vigorously developed in recent years, and the photovoltaic industry has developed rapidly under the strong promotion of national policies. Various photovoltaic module companies have successively launched anti-dust photovoltaic modules and developed many innovative products around the module frames. In particular, the most effective anti-dust effect is the full-screen or full-screen photovoltaic module, which fundamentally improves the characteristics of dust accumulation at the edge of the module from the source.

[0003] However, when installing full-screen or full-screen photovoltaic modules, a rubber pressure block is required to press the front of the full-screen or full-screen photovoltaic module to fix the full-screen or full-screen photovoltaic module. When the pressure of the pressure block pressing the front of the full-screen or full-screen photovoltaic module is large, it may cause the full-screen or full-screen photovoltaic module to burst. In addition, the pressure block is located on the upper side of the full-screen or full-screen photovoltaic module, which affects the lighting efficiency to a certain extent and is not beautiful. Utility Model Content

[0004] The purpose of the present application is to provide a photovoltaic system, a photovoltaic module and a frame thereof, so as to prevent dust accumulation at the edge of the laminate and improve the lighting efficiency.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A frame of a photovoltaic module, comprising:

[0007] A first side plate, wherein a first protrusion protruding toward the laminate installation groove is disposed on the top of the first side plate;

[0008] A support plate, one end of which is connected to the bottom of the first side plate, and the support plate and the first protrusion are located on the same side of the first side plate, and the first side plate and the support plate form a laminate installation groove;

[0009] A second side plate, one end of which is connected to the bottom surface of the support plate;

[0010] A third side plate, a connecting plate and a bottom plate, wherein one end of the connecting plate is connected to the second side plate, and the other end of the connecting plate is connected to one end of the third side plate; and the other end of the third side plate is connected to the bottom plate;

[0011] A fourth side plate, the top and bottom of the fourth side plate are connected to the bottom surface of the support plate and the bottom plate respectively;

[0012] The third side plate, the connecting plate and the first side plate are all located on the same side of the second side plate.

[0013] When the frame of the photovoltaic module provided by the utility model is used, the edge of the laminate is placed in the laminate installation groove, the support plate can support the bottom wall of the laminate, the first protrusion is against the side wall of the laminate, the top surface of the first protrusion can be flush with the top surface of the laminate or the top surface of the first protrusion is lower than the top surface of the laminate. In this way, there is no obstruction at the edge of the laminate, which can effectively prevent dust accumulation at the edge of the laminate. In addition, the first protrusion is used to abut against the side wall of the laminate in the utility model to achieve the positioning and fixing of the laminate. Compared with the prior art of using a rubber block to press on the top surface of the laminate from above, it avoids the pressure on the top surface of the laminate, prevents the laminate from bursting due to excessive pressure, and at the same time ensures that the top surface of the laminate is unobstructed, the lighting efficiency is higher and more beautiful, and it is convenient to clean up dust and snow.

[0014] In addition, the frame of the photovoltaic module provided by the utility model is easier to carry. During the transportation process, the bottom of the first side plate is used as a supporting part, and the operator can carry it by holding the bottom of the first side plate.

[0015] In one implementation, a second protrusion is provided at the other end of the support plate, and the second protrusion is located on the side of the support plate away from the second side plate; in this configuration, with the support effect of the second protrusion, there is a gap between the bottom wall of the laminate and the top surface of the support plate, which facilitates the liquid glue to flow into the gap between the bottom wall of the laminate and the top surface of the support plate, and firmly bonds the laminate in the installation groove. The second protrusion can also prevent the liquid glue from overflowing the gap between the bottom wall of the laminate and the top surface of the support plate.

[0016] Along the direction from the bottom to the top of the first side panel, the height difference between the top of the second protrusion and the top of the first side panel is less than or equal to the thickness of the laminate, ensuring that the top of the first side panel is flush with the top surface of the laminate or the top of the first side panel is lower than the top surface of the laminate, thereby preventing dust accumulation at the edge of the laminate.

[0017] In one implementation, the other end of the second side panel is connected to the bottom panel, and the second side panel is supported as a whole between the support panel and the bottom panel to support the laminate more stably; or, the other end of the second side panel is connected to the connecting plate. With this technical solution, the second side panel, the connecting plate, the bottom panel, the fourth side panel and the support panel together form an angle code cavity, which is convenient for inserting the angle code into the above-mentioned angle code cavity and more convenient for installing and fixing the laminate. In addition, the second side panel, the connecting plate and the third side panel can be formed by bending a single plate, which is more convenient for processing and manufacturing.

[0018] In one implementation, an angle is formed at the connection between the connecting plate and the second side plate; the angle is an acute angle, and the connecting plate gradually tilts upward in a direction away from the second side plate, which can prevent the pressure plate pressed on the connecting plate from shifting and misaligning; or, the angle is a right angle, which is convenient for processing and manufacturing; or, the angle is an obtuse angle, and the connecting plate gradually tilts downward in a direction away from the second side plate, which is convenient for alignment of the pressure plate and the connecting plate during installation.

[0019] In one implementation, the acute angle is α, 60°≤α<90°; or the obtuse angle is β, 90°<β≤120°.

[0020] In one implementation, the top surface of the connecting plate is non-planar; or, the top surface of the connecting plate is planar, so that the regular shape is easy to process and manufacture;

[0021] The non-planar surface includes a wave surface and / or a serrated surface. The bottom surface of the pressing plate and the top surface of the connecting plate are matched with each other in a concave-convex manner, which facilitates the relative positioning between the bottom surface of the pressing plate and the top surface of the connecting plate.

[0022] In one implementation, the first side panel has a third protrusion on the side facing the laminate installation groove, and the third protrusion is inclined toward the support plate. The liquid glue can flow along the third protrusion, which is conducive to the liquid glue flowing to various positions in the gap between the first side panel and the side wall of the laminate, thereby preventing the laminate from being locally loosely bonded; and / or, the bottom surface of the support plate is provided with a first reinforcing rib; and / or, the top surface of the bottom plate is provided with a second reinforcing rib to improve the mechanical strength of the frame.

[0024] A photovoltaic module comprises a laminate and a plurality of frames, at least one of which is a frame of the photovoltaic module as described above; the upper surface of the laminate is not lower than the upper surface of the first side plate. Compared with the prior art, the beneficial effects of the photovoltaic module provided by the embodiment of the present application are the same as those of the above-mentioned frames, which will not be described in detail here.

[0025] In one implementation, the first protrusion of the frame abuts against the side wall of the laminate, and the support plate supports the bottom wall of the laminate. The first protrusion abuts against the side wall of the laminate to achieve positioning and fixing of the laminate, avoids generating pressure on the top surface of the laminate, and prevents the laminate from bursting due to excessive pressure.

[0058] See also Figure 1-Figure 9 The frame 01 of the photovoltaic module provided in the embodiment of the present application includes a first side plate 1, a support plate 2, a second side plate 3, a third side plate 5, a fourth side plate 7, a connecting plate 4 and a bottom plate 6.

[0059] The top of the first side plate 1 is provided with a first protrusion 1a protruding toward the laminate installation groove, and the first protrusion 1a can extend in a direction perpendicular to the first side plate 1. The end of the first protrusion 1a away from the first side plate 1 can be a smooth curved surface, so that the end of the first protrusion 1a away from the first side plate 1 can abut against the side wall of the laminate.

[0060] One end of the support plate 2 is connected to the bottom of the first side plate 1. Specifically, one end of the support plate 2 can be fixedly connected to the bottom of the first side plate 1. The support plate 2 and the first protrusion 1a are located on the same side of the first side plate 1, and the first side plate 1 and the support plate 2 form a laminate installation groove. When the edge of the laminate is located in the laminate installation groove, the support plate 2 supports the bottom wall of the laminate, and the first protrusion 1a abuts against the side wall of the laminate.

[0061] One end of the second side plate 3 is connected to the bottom surface of the support plate 2. That is, the top of the second side plate 3 is connected to the bottom surface of the support plate 2. The other end of the second side plate 3 can be connected to the connecting plate 4 or the bottom plate 6, that is, the bottom of the second side plate 3 is connected to the connecting plate 4 or the bottom plate 6. One end of the connecting plate 4 is connected to the second side plate 3, and the other end of the connecting plate 4 is connected to one end of the third side plate 5; the other end of the third side plate 5 is connected to the bottom plate 6. That is, the top of the third side plate 5 is connected to the connecting plate 4, and the bottom of the third side plate 5 is connected to the bottom plate 6. The two ends of the connecting plate 4 are connected to the second side plate 3 and the third side plate 5 respectively. The top and bottom of the fourth side plate 7 are connected to the bottom surface of the support plate 2 and the bottom plate 6 respectively, that is, the top of the fourth side plate 7 is connected to the bottom surface of the support plate 2, and the bottom of the fourth side plate 7 is connected to the bottom plate 6. According to actual needs, the number of the fourth side plates 7 can be one or more. When the number of the fourth side plates 7 is multiple, the multiple fourth side plates 7 can be arranged in parallel with each other.

[0062] In addition, the third side plate 5, the connecting plate 4 and the first side plate 1 are all located on the same side of the second side plate 3. Specifically, the connecting plate 4 can be located below the supporting plate 2, and the third side plate 5 and the first side plate 1 can be aligned in the vertical direction, which is conducive to saving the installation space of the frame 01 and improving the space utilization rate of the photovoltaic system.

[0063] When the frame 01 of the photovoltaic module provided by the utility model is used, the edge of the laminate is placed in the laminate installation groove, the support plate 2 can support the bottom wall of the laminate, the first protrusion 1a is against the side wall of the laminate, the top surface of the first protrusion 1a can be flush with the top surface of the laminate or the top surface of the first protrusion 1a is lower than the top surface of the laminate. In this way, there is no obstruction at the edge of the laminate, which can effectively prevent dust accumulation at the edge of the laminate. In addition, the first protrusion 1a is used to abut against the side wall of the laminate in the utility model to achieve the positioning and fixing of the laminate. Compared with the prior art that uses a rubber block to press on the top surface of the laminate from above, it avoids the pressure on the top surface of the laminate, prevents the laminate from bursting due to excessive pressure, and at the same time ensures that the top surface of the laminate is unobstructed, the lighting efficiency is higher and more beautiful, and it is convenient to clean up dust and snow.

[0064] In addition, the frame 01 of the photovoltaic module provided by the utility model is more convenient to carry. During the transportation process, the bottom of the first side panel 1 is used as a supporting part, and the operator can just hold the bottom of the first side panel 1 to carry it.

[0065] like Figure 1-Figure 9 As shown, the other end of the support plate 2 is provided with a second protrusion 2a, and the second protrusion 2a is located on the side of the support plate 2 away from the second side plate 3. Specifically, the end of the support plate 2 away from the first side plate 1 is provided with a second protrusion 2a, and the second protrusion 2a protrudes toward the top of the support plate 2. After the laminate is placed in the installation groove, the second protrusion 2a abuts against the bottom wall of the laminate to support the laminate with the second protrusion 2a. In this way, with the support effect of the second protrusion 2a, there is a gap between the bottom wall of the laminate and the top surface of the support plate 2, which facilitates the liquid glue to flow into the gap between the bottom wall of the laminate and the top surface of the support plate 2, and firmly bonds the laminate in the installation groove. The second protrusion 2a can also prevent the liquid glue from overflowing the gap between the bottom wall of the laminate and the top surface of the support plate 2.

[0066] The top of the second protrusion 2a can be a plane to prevent stress concentration when the second protrusion 2a supports the laminate. Of course, the top of the second protrusion 2a can also be any shape such as a curved surface, which is not limited here.

[0067] In the above embodiment, Figure 1As shown, along the direction from the bottom to the top of the first side panel 1, the height difference between the top of the second protrusion 2a and the top of the first side panel 1 is less than or equal to the thickness of the laminate. Specifically, along the direction from the bottom to the top of the first side panel 1, the distance between the top of the second protrusion 2a and the top of the first side panel 1 is H, and H is less than or equal to the thickness of the laminate. When H is less than the thickness of the laminate, the top of the first side panel 1 is lower than the top surface of the laminate; when H is equal to the thickness of the laminate, the top of the first side panel 1 is flush with the top surface of the laminate, thereby preventing the first side panel 1 from being higher than the top surface of the laminate, thereby preventing dust from accumulating at the edge of the laminate.

[0068] In order to further prevent the liquid glue from overflowing the gap between the bottom wall of the laminate and the top surface of the support plate 2, a fourth protrusion 2c can also be set on the top surface of the support plate 2. The fourth protrusion 2c is located between the second protrusion 2a and the first side plate 1. The blocking effect of the fourth protrusion 2c can prevent the liquid glue from overflowing.

[0069] In addition, after the edge of the laminate is placed in the laminate installation groove, the abutment of the first protrusion 1a creates a gap between the first side panel 1 and the side wall of the laminate, and the liquid glue flows into the gap between the first side panel 1 and the side wall of the laminate to bond the laminate in the installation groove. In order to facilitate the liquid glue to flow in the gap between the first side panel 1 and the side wall of the laminate, the first side panel 1 has a third protrusion 1b on the side facing the laminate installation groove, and the third protrusion 1b is inclined in the direction close to the support plate 2. With this arrangement, the liquid glue can flow along the third protrusion 1b, which is conducive to the liquid glue flowing to various positions in the gap between the first side panel 1 and the side wall of the laminate, preventing the laminate from being partially loosely bonded.

[0070] like Figure 1 , Figure 4 and Figure 7 As shown, the other end of the second side panel 3 is connected to the bottom panel 6, that is, the bottom of the second side panel 3 is connected to the bottom panel 6. With this technical solution, the second side panel 3 is supported as a whole between the support panel 2 and the bottom panel 6 to support the laminate more stably. Figure 2-Figure 3 , Figure 5-Figure 6 , Figure 8-Figure 9 As shown, the other end of the second side panel 3 is connected to the connecting plate 4, that is, the bottom of the second side panel 3 is connected to the connecting plate 4. With this technical solution, the second side panel 3, the connecting plate 4, the bottom plate 6, the fourth side panel 7 and the support plate 2 together form an angle code cavity, which is convenient for inserting the angle code into the above-mentioned angle code cavity and more convenient for installing and fixing the laminate. In addition, the second side panel 3, the connecting plate 4 and the third side panel 5 can be formed by bending a single plate, which is more convenient for processing and manufacturing.

[0071] In another specific embodiment, the connection plate 4 and the second side plate 3 form an angle at the connection point, that is, the connection plate 4 and the second side plate 3 form an angle at the connection position. Figure 1-Figure 3 As shown, the angle between the connecting plate 4 and the second side plate 3 can be a right angle. In this case, the connecting plate 4 and the second side plate 3 are perpendicular to each other, which is convenient for processing and manufacturing. Figure 4-Figure 6 As shown, the angle between the connecting plate 4 and the second side plate 3 can be an acute angle. In this technical solution, the angle between the connecting plate 4 and the second side plate 3 is an acute angle, that is, the connecting plate 4 gradually tilts upward in the direction away from the second side plate 3, which can prevent the pressure plate pressed on the connecting plate 4 from being offset or misaligned. Or, Figure 7-Figure 9 As shown, the angle between the connecting plate 4 and the second side plate 3 can be an obtuse angle. In this technical solution, the angle between the connecting plate 4 and the second side plate 3 is an obtuse angle, that is, the connecting plate 4 gradually tilts downward in the direction away from the second side plate 3, which facilitates the alignment of the pressing plate and the connecting plate 4 during the installation process.

[0072] In the above embodiment, the angle between the connecting plate 4 and the second side plate 3 is an acute angle α, 60°≤α<90°. Exemplarily, the acute angle is 60°, 65°, 70°, 75°, 80°, 85° or 89°. Alternatively, the angle between the connecting plate 4 and the second side plate 3 is an obtuse angle β, 90°<β≤120°. Exemplarily, the obtuse angle is 95°, 100°, 105°, 110°, 115° or 120°.

[0073] In another specific embodiment, Figure 4-Figure 6 As shown, the top surface of the connecting plate 4 can be a plane, so that the regular shape is easy to process and manufacture. Alternatively, the top surface of the connecting plate 4 is a non-planar surface, so that the bottom surface of the pressing plate cooperates with the top surface of the connecting plate 4 to prevent the pressing plate pressed on the connecting plate 4 from sliding out of position. Figure 1-Figure 3 and Figure 7-Figure 9 As shown, the non-planar surface includes a wavy surface and / or a serrated surface, and the bottom surface of the pressing plate also includes a wavy surface and / or a serrated surface. The bottom surface of the pressing plate and the top surface of the connecting plate 4 are concave-convexly matched to facilitate the relative positioning between the bottom surface of the pressing plate and the top surface of the connecting plate 4. Of course, the top surface of the connecting plate 4 can also be any other shape, which is not limited here.

[0074] In order to improve the mechanical strength of the frame 01, the bottom surface of the support plate 2 may be provided with a first reinforcing rib 2b, and the number of the first reinforcing rib 2b may be one or more, and illustratively, the number of the first reinforcing rib 2b is one, two, three or more. Preferably, the first reinforcing rib 2b is located between the second side plate 3 and the fourth side plate 7, or the first reinforcing rib 2b may also be located on the side of the second side plate 3 away from the fourth side plate 7.

[0075] In addition, the top surface of the bottom plate 6 may be provided with a second reinforcing rib 6a to improve the mechanical strength of the bottom plate 6. Specifically, when the bottom of the second side plate 3 is connected to the bottom plate 6, the second reinforcing rib 6a may be located between the second side plate 3 and the fourth side plate 7; when the bottom of the second side plate 3 is connected to the connecting plate 4, the number of the second reinforcing rib 6a may be multiple, such as two, three or more.

[0076] Since the side wall and the bottom wall of the laminate are perpendicular to each other, the first side plate 1 and the support plate 2 can also be perpendicular to each other, so that the first side plate 1 and the support plate 2 are L-shaped as a whole, which is convenient for matching with the side wall and the bottom wall of the laminate. Of course, the angle formed at the connection between the first side plate 1 and the support plate 2 can also be an acute angle or an obtuse angle, which is not limited here.

[0077] Similarly, the second side plate 3 and the support plate 2 are perpendicular to each other, so that the second side plate 3 supports the support plate 2 more stably, and the frame 01 is not easy to deform. The first side plate 1, the second side plate 3, the third side plate 5 and the fourth side plate 7 can be arranged parallel to each other to make the frame 01 structure more regular and the overall support for the laminate more stable.

[0078] In the frame 01, the first side panel 1, the support panel 2, the second side panel 3, the third side panel 5, the fourth side panel 7, the connecting panel 4 and the bottom panel 6 can be an integral structure, or the above-mentioned components can be processed separately and then fixedly connected together.

[0079] The embodiment of the present application also provides a photovoltaic assembly, which includes a laminate 02 and a plurality of frames 01. At least one of the frames 01 is a frame 01 of a photovoltaic assembly as provided in any of the above embodiments. In addition, the upper surface of the laminate 02 is not lower than the upper surface of the first side plate 1. Compared with the prior art, the beneficial effects of the photovoltaic assembly provided in the embodiment of the present application are the same as the beneficial effects of the above frame 01, which will not be described in detail here.

[0080] Furthermore, the first protrusion 1a of the frame 01 abuts against the side wall of the laminate 02. Specifically, the first protrusion 1a and the side wall of the laminate 02 may be in direct contact and abutment, or there may be adhesive between the first protrusion 1a and the side wall of the laminate 02, and the first protrusion 1a and the side wall of the laminate 02 may be indirectly abutted. The support plate 2 supports the bottom wall of the laminate 02. Specifically, the support plate 2 may be in direct contact with the bottom wall of the laminate 02, or there may be adhesive between the support plate 2 and the bottom wall of the laminate 02. The first protrusion 1a abuts against the side wall of the laminate 02 to achieve positioning and fixing of the laminate 02, avoid generating pressure on the top surface of the laminate, and prevent the laminate 02 from bursting due to excessive pressure.

[0081] In addition, if Figure 10-12As shown, the embodiment of the present application further provides a photovoltaic system, which includes a photovoltaic module, a bracket and a pressing block 03, wherein the photovoltaic module is the photovoltaic module provided by any of the above embodiments. Particularly, both sides of the pressing block 03 have pressing plates 03a, and the pressing plates 03a on both sides of the pressing block 03 are respectively crimped on the upper sides of the connecting plates 4 of the two adjacent frames 01, and the pressing block 03 is fixedly connected to the bracket 05 by bolts 04. Compared with the prior art, the beneficial effects of the photovoltaic system provided by the embodiment of the present application are the same as the beneficial effects of the above-mentioned photovoltaic modules, which will not be elaborated here. In addition, in the photovoltaic system, a pressing block 03 can be used to simultaneously crimp the connecting plates 4 of the two frames 01 to achieve the fixation of the frame 01, such as Fig.17 As shown, the pressing block 03 and the bracket 05 are fixed by bolts 04 , and there is no need to open bolt holes on the frame 01 , thereby ensuring the mechanical strength of the frame 01 .

[0082] like Figure 13-Figure 16 As shown, the pressing plate 03a includes a pressing plate 03a and a vertical plate 03b, and the pressing plate 03a is connected to the top of the vertical plate 03b. An angle is formed at the connection between the pressing plate 03a and the vertical plate 03b, and the absolute value of the difference between the angle formed at the connection between the pressing plate 03a and the vertical plate 03b and the angle formed at the connection between the connecting plate 4 and the second side plate 3 is 0°-10°. Specifically, the absolute value of the difference between the angle formed at the connection between the pressing plate 03a and the vertical plate 03b and the angle formed at the connection between the connecting plate 4 and the second side plate 3 can be 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°. It can be understood that the angle formed at the connection between the pressing plate 03a and the vertical plate 03b and the angle formed at the connection between the connecting plate 4 and the second side plate 3 do not need to be exactly the same, and it is only necessary to ensure that the pressing plate 03a can be pressed on the connecting plate 4.

[0083] In this way, the pressing plate 03a is pressed on the connecting plate 4, the second side plate 3 is butted against the end of the pressing plate 03a, and the third side wall is butted against the vertical plate 03b, so that the pressing block 03 and the frame 01 are fitted together, saving installation space. Preferably, the angle formed at the connection between the pressing plate 03a and the vertical plate 03b is 60°-120°; illustratively, the angle formed at the connection between the pressing plate 03a and the vertical plate 03b can be 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115° or 120°.

[0084] In addition, in order to ensure that the bottom surface of the pressing plate 03a fits with the top surface of the connecting plate 4, the bottom surface of the pressing plate 03a and the top surface of the connecting plate 4 can be matched in shape, for example, the bottom surface of the pressing plate 03a and the top surface of the connecting plate 4 are both wavy surfaces and / or serrated surfaces.

[0085] like Fig.13 , Fig.14 and Fig.16As shown, the pressing block 03 can be in a Π shape as a whole; or, as Fig.15 As shown, the pressing block 03 can be in the shape of an inverted "J" as a whole, which is easier to process and manufacture.

[0086] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0087] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
