Specific embodiments

[0032] The present utility model will be further described below in conjunction with the embodiments shown in the drawings.

[0033] Embodiment 1

[0034] As Figures 1-3 shown, it is the schematic diagram of the mounting structure for photovoltaic modules of the present utility model. The mounting structure includes a mounting bracket, a main baffle 3, a support member 6, a sealing plate 7, a photovoltaic panel 8 and a disassembly unit. There is a set (i.e., two) of mounting brackets, and the two mounting brackets are arranged oppositely with a mounting space left between them to facilitate the insertion of the photovoltaic panel 8, and at the same time avoid the upper surface of the photovoltaic panel 8 as much as possible to provide sufficient light area for the photovoltaic panel 8.

[0035] As Figure 4The figure is a schematic diagram of the structure of the mounting frame, which includes a support plate 1, a side baffle plate 2, a top plate 4 and a slot 5. The side baffle plate 2 is integrally connected to the top of the support plate 1, and the length of the side baffle plate 2 is the same as that of the support plate 1. The side baffle plate 2 is used to limit the photovoltaic panel 8 after insertion to prevent the photovoltaic panel 8 from swinging during subsequent use, thereby affecting the efficiency of the photovoltaic panel 8 in converting light energy.

[0036] The top plate 4 is integrally connected to the top of the side baffle 2 and extends inward (i.e., the support plate 1 and the top plate 4 are located on the same side of the side baffle 2). The projection area of ​​the top plate 4 on the support plate 1 is smaller than the top view area of ​​the support plate 1 (i.e., the width of the top plate 4 is smaller than the width of the support plate 1).

[0037] After the photovoltaic panel 8 is inserted into the slot 5, the top plate 4 is used to limit the upper surface of the photovoltaic panel 8 to prevent the photovoltaic panel 8 from falling out of the slot 5. Since the width of the top plate 4 is smaller than the width of the support plate 1, it will avoid blocking the light receiving area of ​​the photovoltaic panel 8 as much as possible, thereby improving the light energy conversion efficiency of the photovoltaic panel 8.

[0038] The slot 5 is formed between the support plate 1 , the side baffle plate 2 and the top plate 4 , and the height of the slot 5 is greater than the thickness of the photovoltaic panel 8 , ensuring smooth installation and fixation of the subsequent support member 6 .

[0039] The support members 6 are fixed in the slots 5 at intervals along the length direction of the mounting frame. The photovoltaic panels 8 are inserted into the slots 5 and supported by the support members 6. Under the action of the support members 6, the photovoltaic panels 8 are prevented from sinking and deforming downward under the influence of gravity, thereby affecting the service life of the photovoltaic panels 8 and the conversion efficiency of light energy.

[0040] The main baffle 3 is integrally connected to the same side of the mounting frame, and the photovoltaic panel 8 is inserted into the slot 5 and abuts against the inner side of the main baffle 3, the lower surface of the photovoltaic panel 8 abuts against the support member 6, and the upper surface of the photovoltaic panel 8 abuts against the bottom of the top plate 4. Under the joint action of the main baffle 3, the support member 6 and the top plate 4, the photovoltaic panel 8 is supported and limited, which can prevent the photovoltaic panel 8 from sinking and deforming downward, and at the same time increase the light receiving area of ​​the photovoltaic panel 8.

[0041] The support member 6 is fixed in the slot 5 by fasteners (such as screws) or adhesive, and is arranged in the slot 5 at intervals along the length direction of the mounting frame, and is used to support the photovoltaic panel 8 to prevent the photovoltaic panel 8 from sinking and deforming downward under the influence of gravity, thereby affecting the service life of the photovoltaic panel 8 and the conversion efficiency of light energy.

[0042] By arranging multiple groups of support members 6 at intervals at the bottom of the photovoltaic panel 8, it can not only support the photovoltaic panel 8 and prevent the photovoltaic panel 8 from deforming and sinking downward under the action of gravity, but also leave a distance between adjacent support members 6, which can achieve the effect of heat dissipation to a certain extent.

[0043] The support member 6 is composed of a horizontally arranged main support portion 61 and a secondary support portion integrally connected to the bottom of the main support portion 61. The horizontally arranged main support portion 61 is used to support the photovoltaic panel 8. The horizontal arrangement can ensure sufficient contact area with the photovoltaic panel 8, improve the stability of the photovoltaic panel 8 after fixed installation; at the same time, it can also prevent the photovoltaic panel 8 from tilting and affecting the light-receiving efficiency.

[0044] As Figure 2 , 5 shown, the secondary support portion includes a first support vertical plate 621 and a first support horizontal plate 622. There are two first support vertical plates 621, and the first support vertical plates 621 are integrally connected to both sides of the main support portion 61 and extend away from the photovoltaic panel 8. There are two first support horizontal plates 622, and they are integrally connected to the back side of the bottom of the first support vertical plate 621. As shown in the figure, the first support vertical plate 621 and the first support horizontal plate 622 form an "L" shape, and the main support portion 61 and the secondary support portion form a dovetail groove type to support the photovoltaic panel 8 and prevent the photovoltaic panel 8 from deforming and sinking downward under the action of gravity.

[0045] The main support portion 61 and the secondary support portion form a dovetail groove type, and its internal structure is a cavity type. It can not only save the material cost during processing, reduce the weight of the support member 6, and facilitate installation; at the same time, it can ensure a certain elasticity between the main support portion 61 and the secondary support portion, making it more convenient for the photovoltaic panel 8 to be inserted into the slot 5.

[0046] The secondary support portion is not limited to Figure 5 the shape shown, and it can also be replaced by Figure 3 the shape shown. That is, the secondary support portion includes a second support vertical plate 623 and a second support horizontal plate 624. The second support vertical plate 623 is integrally connected to the bottom of the middle of the main support portion 61, and the second support horizontal plate 624 is integrally connected to the bottom of the second support vertical plate 623 and is arranged parallel to the main support portion 61. The second support vertical plate 623 and the second support horizontal plate 624 form an inverted "T" shape, and the main support portion 61 and the secondary support portion form an "I" shape, which can also play a role in supporting the photovoltaic panel 8.

[0047] In the actual production and use process, the support member 6 is not limited to the above two shapes. As long as the main support portion 61 is arranged horizontally, there are no excessive requirements for the shape of the secondary support portion (the support member 6 can be in the shape of a dovetail groove type, "I" type, loop type, "T" type, etc.).

[0048] The sealing plate 7 is arranged on the side of the mounting rack away from the main baffle 3 and is used to seal the inserted photovoltaic panel 8 and limit the photovoltaic panel 8 (after the photovoltaic panel 8 is installed, the sealing plate 7 can be fixed to one side of the mounting rack by fastening bolts 11 or adhesive). As Figure 1As shown, the disassembly unit includes an inner fixing hole 9, an outer fixing hole 10, and a fastening bolt 11. The inner fixing hole 9 is opened on the side of the mounting bracket away from the main baffle 3, the outer fixing hole 10 penetrates through the sealing plate 7, and internal threads are provided on the inner sides of the inner fixing hole 9 and the outer fixing hole 10.

[0049] The fastening bolt 11 passes through the outer fixing hole 10 and is fixed in the inner fixing hole 9, thereby fixing the sealing plate 7 on one side of the mounting bracket to play a role in sealing the photovoltaic panel 8. When replacing the photovoltaic panel 8 subsequently, reverse-rotate the fastening bolt 11 to remove the sealing plate 7.

[0050] Embodiment Two

[0051] As Figure 6 shown, the technical solution of Embodiment Two is basically the same as that of Embodiment One, with the only difference being the disassembly unit. As Figure 7 shown, the disassembly unit in this embodiment includes an inner buckle 12 and an outer buckle 13. The inner buckle 12 is fixed on the side of the mounting bracket away from the main baffle 3, and the outer buckle 13 is fixed on the side of the sealing plate 7 close to the mounting bracket. The sealing plate 7 is rotatably connected to one side of the mounting bracket through a hinge or a pivot. When the sealing plate 7 rotates to contact the mounting bracket, the outer buckle 13 is engaged in the inner buckle 12, thereby completing the fixed connection between the sealing plate 7 and the mounting bracket. In this embodiment, the sealing plate 7 and the mounting bracket are an integral structure, and the buckling and disassembly of the sealing plate 7 and the mounting bracket are more convenient. During transfer and transportation, the sealing plate 7 will not be lost, and at the same time, there is no need to store bolts and other components separately.

[0052] As Figure 7 shown, the inner buckle 12 includes a first inner abutting plate 121, a first extension plate 122, an abutting groove 123, an outer clamping portion 124, a guiding portion 125, and a second inner abutting plate 126. The first inner abutting plate 121 is fixed on the side of the mounting bracket away from the main baffle 3. There are two first extension plates 122, and they are integrally connected to the outside of the first inner abutting plate 121. An abutting groove 123 is formed between the first inner abutting plate 121 and the first extension plate 122 for accommodating the outer buckle 13 after engagement.

[0053] The outer clamping portion 124 is integrally connected to the side of the first extension plate 122 away from the first inner abutting plate 121 and extends inward (i.e., the distance between the outer clamping portions 124 gradually decreases). The guiding portion 125 is integrally connected to the side of the outer clamping portion 124 away from the first extension plate 122 and extends outward (i.e., the distance between the guiding portions 125 gradually increases). By providing the outer clamping portion 124, the outer buckle 13 after engagement is limited; by providing the guiding portion 125, the outer buckle 13 is guided to ensure that the outer buckle 13 is more easily stuck in the abutting groove 123.

[0054] The second inner abutment plate 126 is integrally connected to a side of the guide portion 125 away from the outer clamping portion 124 and extends horizontally outward. The second inner abutment plate 126 limits the engaged outer buckle 13 to prevent the outer buckle 13 from excessively squeezing the inner buckle 12 when engaged.

[0055] The outer buckle 13 includes a first outer abutment plate 131, a transition portion 132, an inner snap-fitting portion 133, a second extension plate 134 and a second outer abutment plate 135. The transition portion 132 is integrally connected to both sides of the first outer abutment plate 131, and the transition portion 132 is arc-shaped and cooperates with the guide portion 125 to facilitate the buckling of the outer buckle 13.

[0056] The inner snap-fitting portion 133 is integrally connected to the side of the transition portion 132 away from the first outer abutment plate 131 and extends inward (i.e. the distance between the inner snap-fitting portions 133 gradually decreases). After the outer snap-fitting portion 13 is engaged with the inner snap-fitting portion 124, the inner snap-fitting portion 133 abuts against the inner side of the outer snap-fitting portion 124 to limit the sealing plate 7.

[0057] The second extension plate 134 is integrally connected to the side of the inner clamping portion 133 away from the transition portion 132, and the second outer abutment plate 135 is integrally connected to the side of the second extension plate 134 away from the inner clamping portion 133 and extends horizontally outward. The second outer abutment plate 135 is fixed to the side of the sealing plate 7 close to the mounting frame.

[0058] When the sealing plate 7 rotates toward one side of the mounting frame, the outer snap 13 rotates synchronously until it is snapped into the inner snap 12. At this time, the transition portion 132 contacts the guide portion 125, and the guide portion 125 is gradually stretched outward until the first outer abutment plate 131, the transition portion 132 and the inner snap portion 133 are pressed into the abutment groove 123. The guide portion 125 is reset under the action of its own elastic force until the first outer abutment plate 131 fits the first inner abutment plate 121, the inner snap portion 133 is snapped into the outer snap portion 124, and the second outer abutment plate 135 abuts against the side of the second inner abutment plate 126 away from the first inner abutment plate 121.

[0059] By providing the first inner abutment plate 121 and the second inner abutment plate 126, the pressed outer buckle 13 is double-positioned to prevent the outer buckle 13 from being over-pressed and damaging the inner buckle 12. By providing the inner buckle 12 and the outer buckle 13 that cooperate with each other, the sealing plate 7 and the mounting frame are designed into an integral structure to prevent the sealing plate 7 from falling and being lost during transfer and transportation. At the same time, installation and disassembly are more convenient, and there is no need to keep additional parts such as bolts.

[0060] The installation structure for the photovoltaic module of the utility model is provided with slots 5 on the opposite sides of the mounting frame, and the photovoltaic panel 8 is inserted into the slots 5. The photovoltaic panel 8 is supported by the support members 6 to prevent the photovoltaic panel 8 from deforming and denting downward under the action of gravity. At the same time, the support members 6 can improve the structural strength of the mounting frame, thereby improving the wind resistance of the mounting frame and protecting the integrity of the internal photovoltaic panel 8 structure. By providing a detachable sealing plate 7 on the other side of the mounting frame, it plays a role in blocking the inserted photovoltaic panel 8, and at the same time facilitates the disassembly and replacement of the internal photovoltaic panel 8.

[0061] The above embodiments are only used to illustrate the technical concept and features of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, and it cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be covered within the protection scope of the utility model.
