[0002] The frame is the outer framework of a photovoltaic module, typically made of aluminum alloy or other suitable materials. It protects the edges of the solar panel and provides structural support. Currently, frame components often protrude and snap onto the glass panel of the photovoltaic module. This can easily lead to accumulation of dust, snow, and water around the edges of the module. This can block light, affect the module's power generation efficiency, and increase the load on the module. In severe cases, the module can sag, and the weight can exceed the load-bearing capacity of the frame's keel. Summary of the Invention

[0003] The purpose of the utility model is to provide a double-glass anti-dust photovoltaic component frame in order to solve the above problems.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a double-glass anti-dust photovoltaic module frame, including a photovoltaic laminate and a frame body, wherein the photovoltaic laminate has tempered glass layers on both sides, and the two tempered glass layers are provided with notches on the circumferential outer sides and corresponding sides, and the notches are provided correspondingly so as to form a mounting groove extending toward the inner side of the photovoltaic laminate on the circumferential outer side of the photovoltaic laminate, and the top height of the frame body does not exceed the outside of the photovoltaic laminate, and the top side of the frame body has a horizontally arranged frame protrusion corresponding to the mounting groove, the frame protrusion is inserted into the mounting groove, and a mounting groove sealing layer is provided between the outer surface of the frame protrusion and the mounting groove. The photovoltaic laminate is connected to the frame protrusion of the frame body through the mounting groove, and a mounting groove sealing layer is provided between the mounting groove and the frame protrusion, which has a sealing effect. At the same time, the top height of the frame body does not exceed the outside of the photovoltaic laminate, which can ensure that dust, snow, water, etc. on the surface of the photovoltaic laminate can be discharged in time, thereby ensuring the normal operation of the photovoltaic laminate.

[0005] In the aforementioned double-glass, dust-proof photovoltaic module frame, the photovoltaic laminate comprises an outer tempered glass layer, an outer EVA film layer, a solar cell layer, an inner EVA film layer, and an inner tempered glass layer, arranged sequentially from top to bottom. The outer EVA film layer, solar cell layer, and inner EVA film layer are respectively positioned between the outer tempered glass layer and the inner tempered glass layer, and the outer and inner tempered glass layers extend circumferentially outward of the outer EVA film layer, solar cell layer, and inner EVA film layer, respectively. The photovoltaic laminate is formed by high-temperature lamination of the outer tempered glass layer, the outer EVA film layer, the solar cell layer, the inner EVA film layer, and the inner tempered glass layer in a laminating machine to form a composite layer.

[0006] In the above-mentioned double-glass anti-dust photovoltaic module frame, the inner side of the installation groove extends to the outer side of the outer EVA film layer, the solar cell layer and the inner EVA film layer.

[0007] In the aforementioned double-glass anti-dust photovoltaic module frame, the frame body includes vertically corresponding outer and inner frame edges, as well as horizontally corresponding upper and lower frame edges. The outer, inner, upper, and lower frame edges together form a rectangular frame, and the raised portion is disposed parallel to and above the upper frame edge. The frame body not only protects the photovoltaic laminate but also provides structural support for the entire photovoltaic laminate, effectively protecting the edges of the photovoltaic laminate from physical damage.

[0008] In the aforementioned double-glass, dust-proof photovoltaic module frame, the upper end of the outer edge of the frame has an outer extension extending upward, and the frame protrusion is located on a side of the outer extension near the upper edge of the frame. The frame is designed and manufactured to withstand pressure, vibration, and loads under various environmental conditions, ensuring stable operation and long-term use of the photovoltaic laminate.

[0009] In the aforementioned double-glass anti-dust photovoltaic module frame, the upper end of the outer extension of the frame extends beyond one side of the frame protrusion and is flush with the side of the outer tempered glass layer away from the outer EVA film layer. This ensures that dust, snow, water, etc. on the surface of the photovoltaic laminate can be promptly drained, thereby ensuring the normal operation of the photovoltaic laminate.

[0010] In the above-mentioned double-glass anti-dust photovoltaic module frame, one side of the frame convex portion has an outer convex surface of the frame corresponding to the gap of the outer tempered glass layer, and the other side of the frame convex portion has an inner convex surface of the frame corresponding to the gap of the inner tempered glass layer. A frame side convex surface corresponding to the circumferential outer side of the outer EVA film layer, the solar cell layer and the inner EVA film layer is provided between the outer convex surface of the frame and the side of the inner convex surface of the frame away from the outer extension portion of the frame.

[0011] In the aforementioned double-glass, dust-proof photovoltaic module frame, the mounting groove sealant layers are disposed on the outer convex surface, the inner convex surface, and the side convex surfaces of the frame, respectively. An outer glass edge sealant layer connected to one side of the mounting groove sealant layer is disposed between the outer extension of the frame and the circumferential outer side of the outer tempered glass layer. An inner glass edge sealant layer connected to the other side of the mounting groove sealant layer is disposed between the outer extension of the frame and the circumferential outer side of the inner tempered glass layer. An inner glass side sealant layer is disposed between the side of the inner tempered glass layer away from the inner EVA film layer and the upper side of the frame. The outer glass edge sealant layer, the inner glass edge sealant layer, and the inner glass side sealant layer prevent water vapor, moisture, or other environmental factors from entering the interior of the photovoltaic laminate, thereby improving the durability and stability of the photovoltaic laminate and reducing performance degradation or failures caused by moisture intrusion.

[0012] In the above-mentioned double-glass anti-dust photovoltaic module frame, frame glue overflow grooves are respectively provided on the outer convex surface of the frame, the inner convex surface of the frame and the upper side of the frame.

[0013] In the above-mentioned double-glass anti-dust photovoltaic component frame, the upper side of the frame away from the outer side of the frame exceeds the frame protrusion, and the bottom side of the frame away from the outer side of the frame exceeds the upper side of the frame.

[0014] Compared with the existing technology, the advantages of this utility model are:

[0015] 1. The design of the photovoltaic laminate and frame of the device can enable dust, snow, water, etc. on the surface of the photovoltaic laminate to be discharged in time, ensuring the power generation of the photovoltaic laminate, reducing the load on the surface of the photovoltaic laminate, and reducing the impact of bad weather on the photovoltaic laminate.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1-4 As shown, a double-glass anti-dust photovoltaic component frame includes a photovoltaic laminate 1 and a frame body 2. The photovoltaic laminate 1 has tempered glass layers 11 on both sides. The two tempered glass layers 11 are provided with notches 12 on the circumferential outer sides and corresponding sides respectively. The notches 12 are correspondingly arranged to form an installation groove 13 extending toward the inner side of the photovoltaic laminate 1 on the circumferential outer side of the photovoltaic laminate 1. The top height of the frame body 2 does not exceed the outside of the photovoltaic laminate 1. One side of the top of the frame body 2 has a horizontally arranged frame protrusion 21 corresponding to the installation groove 13. The frame protrusion 21 is inserted into the installation groove 13 and an installation groove sealant layer 22 is provided between the outer surface of the frame protrusion 21 and the installation groove 13. The photovoltaic laminate 1 is connected to the frame protrusion 21 of the frame body 2 through the installation groove 13. An installation groove sealant layer 22 is arranged between the installation groove 13 and the frame protrusion 21, which has a sealing effect. At the same time, the top height of the frame body 2 does not exceed the outside of the photovoltaic laminate 1. This can ensure that dust, snow, water, etc. on the surface of the photovoltaic laminate 1 can be discharged in time, thereby ensuring the normal operation of the photovoltaic laminate 1.

[0025] like Figure 3As shown, the photovoltaic laminate 1 includes, arranged from top to bottom, an outer tempered glass layer 14, an outer EVA film layer 15, a solar cell layer 16, an inner EVA film layer 17, and an inner tempered glass layer 18. The outer EVA film layer 15, the solar cell layer 16, and the inner EVA film layer 17 are respectively located between the outer tempered glass layer 14 and the inner tempered glass layer 18, and the outer tempered glass layer 14 and the inner tempered glass layer 18 extend circumferentially outward of the outer EVA film layer 15, the solar cell layer 16, and the inner EVA film layer 17, respectively. The photovoltaic laminate 1 is formed by high-temperature lamination of the outer tempered glass layer 14, the outer EVA film layer 15, the solar cell layer 16, the inner EVA film layer 17, and the inner tempered glass layer 18 in a laminating machine to form a composite layer.

[0026] The inner side of the mounting groove 13 extends to the outer side of the outer EVA film layer 15 , the solar cell layer 16 and the inner EVA film layer 17 .

[0027] like Figure 4 As shown, the frame body 2 includes a frame outer side 23 and a frame inner side 24 that are vertically correspondingly arranged, and a frame upper side 25 and a frame bottom side 26 that are horizontally correspondingly arranged, and the frame outer side 23, the frame inner side 24, the frame upper side 25 and the frame bottom side 26 are enclosed to form a rectangular frame, and the frame protrusion 21 is arranged parallel to the upper side 25 of the frame. The frame body 2 not only protects the photovoltaic laminate 1, but also provides structural support for the entire photovoltaic laminate 1. The frame body 2 can effectively protect the edge of the photovoltaic laminate 1 from physical damage. The two notches 12 form a mounting groove 13. Compared with the prior art, the notches 12 are opened on the photovoltaic glass to facilitate processing, reduce the difficulty and cost of photovoltaic module production, increase the distance between the frame and the bus bar of the photovoltaic laminate 1, increase the creepage distance or minimum electrical clearance, and improve the safety and reliability of the photovoltaic module.

[0028] The upper end of the outer edge 23 of the frame has an upwardly extending outer edge 27, and the frame protrusion 21 is provided on a side of the outer edge 27 near the upper edge 25 of the frame. The design and manufacture of the frame body 2 can withstand pressure, vibration, and loads under various environmental conditions, ensuring the stable operation and long-term use of the photovoltaic laminate 1.

[0029] like Figure 2 As shown, the upper end of the outer frame extension 27 extends beyond one side of the frame protrusion 21 and is flush with the side of the outer tempered glass layer 14 away from the outer EVA film layer 15. This ensures that dust, snow, water, etc. on the surface of the photovoltaic laminate 1 can be discharged in a timely manner, thereby ensuring the normal operation of the photovoltaic laminate 1.

[0030] like Figure 4As shown, one side of the frame protrusion 21 has a frame outer convex surface 28 corresponding to the notch 12 of the outer tempered glass layer 14, and the other side of the frame protrusion 21 has a frame inner convex surface 29 corresponding to the notch 12 of the inner tempered glass layer 18, and a frame side convex surface 30 corresponding to the circumferential outer side of the outer EVA film layer 15, the solar cell layer 16 and the inner EVA film layer 17 is provided between the frame outer convex surface 28 and the frame inner convex surface 29 away from the side of the frame outer extension 27.

[0031] like Figure 2 As shown, the mounting groove sealant layer 22 is respectively disposed on the outer convex surface 28 of the frame, the inner convex surface 29 of the frame, and the side convex surface 30 of the frame. An outer glass edge sealant layer 31 connected to one side of the mounting groove sealant layer 22 is disposed between the outer extension portion 27 of the frame and the circumferential outer side of the outer tempered glass layer 14. An inner glass edge sealant layer 32 connected to the other side of the mounting groove sealant layer 22 is disposed between the outer extension portion 27 of the frame and the circumferential outer side of the inner tempered glass layer 18. An inner glass side sealant layer 33 is disposed between the side of the inner tempered glass layer 18 away from the inner EVA film layer 17 and the upper side edge 25 of the frame. The outer glass edge sealant layer 31, the inner glass edge sealant layer 32, and the inner glass side sealant layer 33 can prevent water vapor, moisture, or other environmental factors from entering the interior of the photovoltaic laminate 1, thereby helping to improve the durability and stability of the photovoltaic laminate 1 and reduce performance degradation or failures caused by moisture intrusion. The frame protrusion 21, the mounting groove 13, and the mounting groove sealant layer 22 form a labyrinth sealing structure. Compared with the prior art, the sealing effect is significantly improved, thereby enhancing the safety and usability of the photovoltaic module.

[0032] like Figure 4 As shown, frame glue overflow grooves 34 are respectively provided on the frame outer convex surface 28 , the frame inner convex surface 29 and the frame upper side 25 .

[0033] The side of the frame upper side 25 away from the frame outer side 23 exceeds the frame protrusion 21 , and the side of the frame bottom side 26 away from the frame outer side 23 exceeds the frame upper side 25 .

[0034] The principle of this embodiment is:

[0035] The photovoltaic laminate 1 is connected to the frame protrusion 21 of the frame body 2 through the installation groove 13. An installation groove sealant layer 22 is arranged between the frame protrusion 21 and the installation groove 13, which plays a role of sealing and waterproofing, thereby improving the durability and stability of the photovoltaic laminate 1. At the same time, the frame body 2 under the inner tempered glass layer 18 plays a supporting role, which can ensure that the photovoltaic laminate 1 can operate stably and be used for a long time, and the top height of the frame body 2 does not exceed the outside of the photovoltaic laminate 1, which can ensure that the dust, snow, water, etc. on the surface of the photovoltaic laminate 1 can be discharged in time, thereby ensuring the normal operation of the photovoltaic laminate 1.
