Description

Technical Field

[0001] This application relates to the technical field of photovoltaic power generation, and more specifically, to a frame assembly and a photovoltaic system. Background Art

[0002] Photovoltaic modules are usually installed and fixed through frames. In related technologies, certain blockages will occur during the connection between the frame and the photovoltaic module, reducing the effective area of the photovoltaic module, thereby affecting the power generation efficiency of the photovoltaic module. In addition, photovoltaic modules are usually installed outdoors. Affected by environmental factors, rainwater and dust will accumulate on the upper surface of the photovoltaic module. Due to the blockage caused by the frame, rainwater and dust cannot be discharged. Over time, it will affect the power generation efficiency of the photovoltaic module, and in severe cases, it will cause hot spots, reducing the performance and service life of the photovoltaic module. Summary of the Utility Model

[0003] Embodiments of this application provide a frame assembly and a photovoltaic system.

[0004] The frame assembly of the embodiments of this application is used to fix a photovoltaic module. The frame assembly includes a frame, and the frame includes:

[0005] A frame body, on the upper side of which there is a first fixing surface;

[0006] A first fixing plate, which is arranged on the first fixing surface. The first fixing plate includes a second fixing surface that is substantially perpendicular to the first fixing surface. The second fixing surface and the first fixing surface form a fixing groove that is open on both sides, and the fixing groove is used to fix the photovoltaic module.

[0007] For the frame assembly provided by this application, since the fixing groove is open on both sides, after the photovoltaic module is installed in the fixing groove, its upper surface can be exposed from the fixing groove. Therefore, the upper surface of the photovoltaic module will not be blocked by the frame, increasing the effective area of the photovoltaic module, thereby improving the power generation efficiency of the photovoltaic module. On the other hand, rainwater or dust can also flow away or be removed from the upper surface of the photovoltaic module, avoiding the influence caused by the long-term inability to remove rainwater and dust, and ensuring the performance and service life of the photovoltaic module.

[0008] In some embodiments, the frame body is in the shape of a rectangular frame and is formed with mounting holes. The frame assembly further includes corner brackets, and the corner brackets are configured to match the mounting holes to assemble two such frames.

[0009] In this way, adjacent frames can be connected through corner brackets to improve the overall structural strength of the frame assembly.

[0010] In some embodiments, the inner wall of the mounting hole is provided with fixing protrusions, and the fixing protrusions are configured to press against the outer surface of the corner code when the corner code is mounted in the mounting hole.

[0011] In this way, the fixing protrusions can play a certain protective role for the mounting hole and at the same time provide a certain margin.

[0012] In some embodiments, an anti-slip portion is formed on the outer surface of the frame body.

[0013] In this way, the friction force on the outer surface of the frame body can be increased, which is convenient for handling.

[0014] In some embodiments, the frame body includes a side surface that is substantially perpendicularly connected to the first fixing surface at an end of the first fixing surface away from the first fixing plate, the frame further includes a second fixing plate that vertically extends from an end of the side surface away from the first fixing surface, and the frame assembly further includes a fixing component for fixing the frame. The fixing component is configured to fix the frame to the mounting object by pressing against the second fixing plate.

[0015] In this way, the fixing of the frame can be realized through the fixing component.

[0016] In some embodiments, a mounting portion that cooperates with the fixing component is formed on the second fixing plate.

[0017] In this way, the fixing of the frame is realized by the cooperation of the mounting portion and the fixing component, which is beneficial to reducing the installation difficulty.

[0018] In some embodiments, the height of the first fixing plate is less than or equal to the thickness of the photovoltaic module.

[0019] In this way, it can be avoided that the first fixing plate hinders the flow or removal of rainwater or dust from the upper surface of the photovoltaic module.

[0020] In some embodiments, the cross-sectional area of the first fixing plate gradually decreases from the first fixing surface in a direction away from the frame body.

[0021] In this way, it is beneficial to improve the structural strength of the first fixing plate and at the same time reduce the production cost.

[0022] In some embodiments, glue-receiving grooves are provided on the first fixing surface and / or the second fixing surface.

[0023] In this way, the contact area between the silica gel and the frame is increased, and the mechanical properties of the frame are improved.

[0024] A photovoltaic system according to another embodiment of the present application includes a photovoltaic module and the frame assembly described in any one of the above. The photovoltaic module is fixed on the fixing groove by silicone, and at least one side of the upper surface of the photovoltaic module is completely exposed.

[0025] In this way, at least one side can be used for rainwater or dust to flow away or be removed from the upper surface of the photovoltaic module.

[0041] Photovoltaic modules are usually installed and fixed through frames. In the related art, certain occlusion will occur during the connection between the frame and the photovoltaic module, reducing the effective area of the photovoltaic module, thereby affecting the power generation efficiency of the photovoltaic module; in addition, photovoltaic modules are usually installed outdoors. Affected by environmental factors, rainwater and dust will accumulate on the upper surface of the photovoltaic module. Due to the occlusion caused by the frame, the rainwater and dust cannot be discharged. Over time, it will affect the power generation efficiency of the photovoltaic module, and in severe cases, it will cause hot spots, reducing the performance and service life of the photovoltaic module.

[0042] Please refer to Figure 1 , this application provides a photovoltaic system 1000. The photovoltaic system 1000 includes a photovoltaic module 200 and a frame assembly 100. The frame assembly 100 includes a frame 10. The frame 10 includes a frame body 11 and a first fixing plate 12. A first fixing surface 111 is provided on the upper side of the frame body 11; the first fixing plate 12 is arranged on the first fixing surface 111. The first fixing plate 12 includes a second fixing surface 121 that is substantially perpendicular to the first fixing surface 111. The second fixing surface 121 and the first fixing surface 111 form a fixing groove 13 that is open on both sides. The fixing groove 13 is used to fix the photovoltaic module 200.

[0043] For the frame assembly 100 provided in this application, since the fixing groove 13 is open on both sides, after the photovoltaic module 200 is installed in the fixing groove 13, its upper surface can be exposed from the fixing groove 13. Therefore, the upper surface of the photovoltaic module 200 will not be occluded by the frame 10, increasing the effective area of the photovoltaic module 200, thereby improving the power generation efficiency of the photovoltaic module 200. On the other hand, rainwater or dust can also flow away or be removed from the upper surface of the photovoltaic module 200, avoiding the influence caused by the long-term inability to remove rainwater and dust, and ensuring the performance and service life of the photovoltaic module 200.

[0044] Specifically, please refer to Figures 1 to 3 , the photovoltaic module 200, also known as a solar panel or a photovoltaic panel, is a device that converts sunlight into electrical energy. It is the core part of a solar power generation system, responsible for converting solar energy into direct current electrical energy to provide power for various applications.

[0045] The frame 10, also known as the purlin, generally refers to the metal material that is perpendicular to the photovoltaic module 200 and is used to fix the photovoltaic module 200. It is usually located on both sides or around the photovoltaic module 200 and is one of the important materials of the photovoltaic module 200, playing a key role in supporting and fixing the photovoltaic module 200.

[0046] In the embodiment of the present application, the fixing groove 13 is in an L shape, the photovoltaic module 200 is placed on the fixing groove 13, and silicone 40 is applied to the part of the lower surface of the photovoltaic module 200 in contact with the frame 10 to achieve adhesive connection.

[0047] Furthermore, a right angle is formed between the lower surface and the side of the photovoltaic module 200, and the right angle formed between the lower surface and the side is fixed in the fixing groove 13.

[0048] In some embodiments, the fixing groove 13 can also be of other shapes. However, it should be noted that when the photovoltaic module 200 is installed in the fixing groove 13, the frame 10 cannot block the upper surface of the photovoltaic module 200.

[0049] In some embodiments, the photovoltaic module 200 and the frame 10 can also be bonded with other types of glue. The specific type of glue can be selected according to actual needs and will not be elaborated here.

[0050] In the embodiment of the present application, the first fixing plate 12 and the frame main body 11 are an integrally formed one-piece structure. In other embodiments, the first fixing plate 12 and the frame main body 11 can also be formed by separate processing and then connected by fasteners.

[0051] Please refer to Figure 2 and Figure 3 , in some embodiments, the frame main body 11 is in a rectangular frame shape and is formed with mounting holes 112. The frame assembly 100 further includes corner brackets 20, and the corner brackets 20 are configured to match the mounting holes 112 to assemble two frames 10.

[0052] In this way, the adjacent frames 10 can be connected through the corner brackets 20 to improve the overall structural strength of the frame assembly 100.

[0053] Specifically, the corner bracket 20 is a hardware part for connecting members intersecting at a 90-degree right angle. Through its unique structure and material, it can effectively connect and fix various members to ensure the stability and safety of the overall structure.

[0054] In the embodiment of the present application, the inside of the frame body 11 is hollow, and its cross-section is in the shape of a rectangular frame. Installation holes 112 are formed at both ends of the hollow frame body 11. The installation holes 112 are rectangular. Both ends of the corner fitting 20 are respectively inserted into the two installation holes 112 of two adjacent frames 10 to realize the connection of the two adjacent frames 10.

[0055] In the embodiment of the present application, the photovoltaic module 200 is rectangular. Therefore, after the frames 10 are connected end to end, a rectangular frame also needs to be formed. As Figure 2 shown, chamfer surfaces 115 are provided at the joints of the two ends in the length direction of the frame 10 and the adjacent frames. The chamfer surfaces 115 form an angle of 30° to 60° with the outer surface of the frame 10. Preferably, the chamfer surfaces 115 form an angle of 45° with the outer surface of the frame 10. With such a setting, when two adjacent frames 10 are connected, the corners of the photovoltaic module 200 can be better fixed and protected.

[0056] In other embodiments, the angle formed by the chamfer surface 115 and the outer surface of the frame 10 can be selected according to the actual shape and actual needs of the photovoltaic module 200.

[0057] Furthermore, an interference fit is provided between the corner fitting 20 and the installation hole 112, so as to prevent the connection between the corner fitting 20 and the frame 10 from loosening and causing the frame 10 to fall off during use.

[0058] It is easy to understand. Please refer to Figure 2 , since an interference fit is provided between the corner fitting 20 and the installation hole 112, in order to facilitate the installation between the corner fitting 20 and the installation hole 112, a convex portion can also be provided on the side surface of the corner fitting 20 for abutting against the inner wall of the installation hole 112 to form an interference fit. Optionally, the convex portion can be a tooth-shaped convex, a dot-shaped convex, a rib-shaped convex, etc. The specific shape of the convex portion can be selected according to actual needs. In the embodiment of the present application, the convex portion is a tooth-shaped convex.

[0059] In some embodiments, the corner fitting 20 can also be arranged inside or outside the joint of two adjacent frames 10. Specifically, both ends of the corner fitting 20 are respectively attached to the outer side surfaces or the inner side surfaces of two adjacent frames 10 so that the two adjacent frames 10 are connected. Optionally, the connection manner between the corner fitting 20 and the outer side surface or the inner side surface of the frame 10 can be welding connection, adhesive connection or fastener connection.

[0060] In some embodiments, other structural members can also be used to connect two adjacent frames 10. The specific types of the connecting members can be selected according to actual needs, and will not be elaborated here.

[0061] Please refer to Figure 2 and Figure 3, in some embodiments, a fixing protrusion 113 is provided on the inner wall of the mounting hole 112, and the fixing protrusion 113 is configured to press against the outer surface of the corner fitting 20 when the corner fitting 20 is installed in the mounting hole 112.

[0062] In this way, the fixing protrusion 113 can play a certain protective role for the mounting hole 112 and at the same time provide a certain margin.

[0063] Specifically, in the embodiments of the present application, the fixing protrusion 113 is a rib-like structure provided on the inner wall of the mounting hole 112 along the length direction of the frame 10, and the fixing protrusions 113 are provided on two relatively arranged inner walls of the rectangular mounting hole 112. Further, the number of the fixing protrusions 113 provided on each surface provided with the fixing protrusion 113 is multiple, and the multiple fixing protrusions 113 can make the force pressing against the surface of the corner fitting 20 more uniform, thereby preventing the frame 10 or the corner fitting 20 from being deformed during use.

[0064] In some embodiments, the fixing protrusion 113 can also be set in other shapes, such as bump or boss. The specific structure of the fixing protrusion 113 can be selected according to actual needs and will not be elaborated here.

[0065] In some embodiments, the fixing protrusion 113 can also be provided on more inner wall surfaces of the mounting hole 112 to make the fixation between the corner fitting 20 and the mounting hole 112 more firm.

[0066] Please refer to Figure 2 and Figure 3 In some embodiments, an anti-slip portion 114 is formed on the outer surface of the frame body 11.

[0067] In this way, the friction force on the outer surface of the frame body 11 can be increased, which is convenient for handling.

[0068] Specifically, in the embodiments of the present application, the anti-slip portion 114 is a V-shaped anti-slip groove provided on the outer surface of the frame body 11. In other embodiments of the application, other forms of anti-slip patterns can also be selected, such as linear anti-slip patterns, tooth-shaped anti-slip patterns, bump anti-slip patterns, etc.

[0069] In some embodiments of the application, the anti-slip portion 114 can also be a part of the frame body 11, that is, the anti-slip portion 114 can be an anti-slip pad or an anti-slip strip provided on the outer surface of the frame body 11. Optionally, the material of the anti-slip pad or the anti-slip strip is rubber, latex, plastic or foam, etc. Further, anti-slip patterns can also be provided on the anti-slip pad or the anti-slip strip for further enhancing the anti-slip effect. Optionally, the anti-slip patterns are tooth-shaped anti-slip patterns, linear anti-slip patterns, bump anti-slip patterns, etc.

[0070] In some application embodiments, the anti-slip portion 114 may also be provided on the outer side of the first fixing plate 12 or other positions of the frame 10. Specifically, the position of the anti-slip portion 114 can be selected according to actual needs, and will not be elaborated here.

[0071] Please refer to Figures 3 to 6 , in some embodiments, the frame body 11 includes a side surface that is substantially perpendicular to the first fixing surface 111 at one end of the first fixing surface 111 away from the first fixing plate 12. The frame 10 further includes a second fixing plate 15 that extends perpendicularly from one end of the side surface away from the first fixing surface 111. The frame assembly 100 further includes a fixing component 30 for fixing the frame 10. The fixing component 30 is configured to fix the frame 10 to the installation object by pressing against the second fixing plate 15.

[0072] In this way, the fixing of the frame 10 can be achieved through the fixing component 30.

[0073] Specifically, in the embodiments of the present application, the second side wall 117 of the frame body 11 opposite to the first side wall 116 where the first fixing plate 12 is installed extends towards the photovoltaic module 200 to form the second fixing plate 15. The second fixing plate 15 is perpendicularly arranged with the first fixing plate 12. Further, the fixing component 30 cooperates to fix the frame 10 to the installation object by pressing against the second fixing plate 15.

[0074] In some embodiments, the second fixing plate 15 may also be provided at other positions of the frame body 11. Specifically, the position of the second fixing plate 15 can be selected according to actual needs, and will not be elaborated here.

[0075] In the embodiments of the present application, the second fixing plate 15 and the frame body 11 are of an integrally formed structure by one-piece processing. In other embodiments, the second fixing plate 15 and the frame body 11 can also be connected by fasteners after being separately processed and formed.

[0076] In some embodiments, the second fixing plate 15 may not be provided, and the frame 10 is fixed to the installation object through other connection forms. Optionally, the connection form can be fastener connection, bonding, riveting, welding, etc.

[0077] Please refer to Figures 6 to 8 , in some embodiments, an installation portion 151 that cooperates with the fixing component 30 is formed on the second fixing plate 15.

[0078] In this way, the fixing of the frame 10 is achieved through the cooperation of the installation portion 151 and the fixing component 30, which is beneficial to reducing the installation difficulty.

[0079] Specifically, please refer to Figure 6, in the embodiments of the present application, the fixing component 30 is a pressing block, and the mounting portion 151 is a protrusion or groove provided on the second fixing plate 15 for cooperating with the pressing block. The protrusion or groove cooperates with the pressing block to fix the frame 10 on the mounting object.

[0080] In some embodiments, the fixing component 30 can also be a fastener such as a bolt or a rivet. At this time, the mounting portion 151 is a through hole provided on the second fixing plate 15, and the frame 10 can be installed and fixed on the mounting object through the fastener passing through the through hole.

[0081] In some embodiments, the fixing component 30 and the mounting portion 151 can also be a buckle and a slot that are used in cooperation. It is easy to understand that a buckle or a slot can be provided on the second fixing plate 15, the fixing component 30 is a slot or a buckle that cooperates with it, and the frame 10 is installed and fixed on the mounting object through the snap connection with the fixing component 30.

[0082] Please refer to Figure 1 , in some embodiments, the height of the first fixing plate 12 is less than or equal to the thickness of the photovoltaic module 200.

[0083] In this way, it can be avoided that the first fixing plate 12 hinders the rainwater or dust from flowing away or being removed from the upper surface of the photovoltaic module 200.

[0084] Specifically, in the embodiments of the present application, the height of the first fixing plate 12 is equal to the thickness of the photovoltaic module 200. It is easy to understand that after the photovoltaic module 200 and the frame 10 are installed, the upper surface of the first fixing plate 12 is flush with the upper surface of the photovoltaic module 200.

[0085] In other embodiments, the height of the first fixing plate 12 is less than the thickness of the photovoltaic module 200. It is easy to understand that after the photovoltaic module 200 and the frame 10 are installed, the upper surface of the first fixing plate 12 is lower than the upper surface of the photovoltaic module 200.

[0086] In some embodiments, the cross-sectional area of the first fixing plate 12 gradually decreases in the direction away from the frame body 11 starting from the first fixing surface 111.

[0087] In this way, it is beneficial to improve the structural strength of the first fixing plate 12 and at the same time reduce the production cost.

[0088] Specifically, in the embodiments of the present application, the cross-section of the first fixing plate 12 along the height direction is approximately trapezoidal, the thickness of the first fixing plate 12 gradually decreases from the bottom to the top, and the thickest part of the first fixing plate 12 is greater than the thickness of the side wall of the frame body 11.

[0089] In other embodiments, it is also possible to select to provide a reinforcing portion on the side of the first fixing plate 12 away from the photovoltaic module 200. The reinforcing portion is triangular. Further, a hollowing may be provided on the reinforcing portion to effectively save costs while ensuring strength.

[0090] Please refer to Figures 3 to 6 , in some embodiments, glue receiving grooves 14 are provided on the first fixing surface 111 and / or the second fixing surface 121.

[0091] In this way, the contact area between the silica gel 40 and the frame 10 is increased, and the mechanical properties of the frame 10 are improved.

[0092] Specifically, in some embodiments, glue receiving grooves 14 are provided on the first fixing surface 111 and the second fixing surface 121. The glue receiving grooves 14 are arranged along the length direction of the first fixing surface 111 and the second fixing surface 121. The number of the glue receiving grooves 14 can be selected according to the width of the first fixing surface 111 and the second fixing surface 121. That is, when the widths of the first fixing surface 111 and the second fixing surface 121 are larger, the number of the glue receiving grooves 14 can be multiple; when the widths of the first fixing surface 111 and the second fixing surface 121 are smaller, the number of the glue receiving grooves 14 can be one.

[0093] In some embodiments, it is possible to select to provide the glue receiving grooves 14 only on the first fixing surface 111. The glue receiving grooves 14 are arranged along the length direction of the first fixing surface 111. The number of the glue receiving grooves 14 can be selected according to the width of the first fixing surface 111. That is, when the width of the first fixing surface 111 is larger, the number of the glue receiving grooves 14 can be multiple; when the width of the first fixing surface 111 is smaller, the number of the glue receiving grooves 14 can be one.

[0094] In some embodiments, it is also possible to select to provide the glue receiving grooves 14 only on the second fixing surface 121. The glue receiving grooves 14 are arranged along the length direction of the second fixing surface 121. The number of the glue receiving grooves 14 can be selected according to the width of the second fixing surface 121. That is, when the width of the second fixing surface 121 is larger, the number of the glue receiving grooves 14 can be multiple; when the width of the second fixing surface 121 is smaller, the number of the glue receiving grooves 14 can be one.

[0095] Optionally, the cross-sectional shape of the glue receiving groove 14 can be rectangular, semi-circular, V-shaped, etc. The specific cross-sectional shape of the glue receiving groove 14 can be selected according to actual needs.

[0096] Preferably, the cross-section of the glue receiving groove 14 can be a closed shape with a smaller opening width and a larger inner cavity width. In this way, after the glue in the glue receiving groove 14 dries, a clamping portion can be formed and clamped in the glue receiving groove 14, thereby preventing the glue from falling off the frame 10.

[0097] Please refer to Figure 2, in some embodiments, the upper surface of at least one side of the photovoltaic module 200 is completely exposed.

[0098] In this way, at least one side can be used for rainwater or dust to flow away or be removed from the upper surface of the photovoltaic module 200.

[0099] Specifically, in the embodiments of the present application, four frames 10 are installed on the photovoltaic module 200. That is, the entire upper surface of the photovoltaic module 200 is completely exposed. At this time, the photovoltaic module 200 has a light-receiving surface with the largest effective area, and the power generation efficiency of the photovoltaic module 200 is the highest. In addition, rainwater or dust can flow away or be removed from the edge of any side of the upper surface of the photovoltaic module 200.

[0100] In some embodiments, at least one frame 10 can also be installed on the photovoltaic module 200, and conventional purlins are installed at the remaining edges. That is, the upper surface of at least one side of the photovoltaic module 200 is completely exposed. At this time, the side of the photovoltaic module 200 where the frame 10 is installed needs to be placed at a lower position. It is easy to understand that the photovoltaic module 200 is usually inclined.
