Description

Technical Field

[0001] This application belongs to the field of photovoltaic technology, specifically relating to a photovoltaic installation structure and a photovoltaic building. Background Technology

[0002] Building Integrated Photovoltaics (BIPV) is a technology that uses photovoltaic (PV) modules installed on the roof of a building to provide electricity. BIPV not only meets the requirements of architectural aesthetics, lighting, and safety, but also avoids the need for PV modules to occupy land resources, making it a green and environmentally friendly technology.

[0003] In existing technologies, photovoltaic modules are typically installed on building roofs using clamps and fasteners. Specifically, clamps are pressed onto the top of the frames of adjacent photovoltaic modules, and then fasteners are used to connect the clamps to the building roof.

[0004] However, due to the small contact area between the clamping block and the frame of the photovoltaic module, the load applied by the clamping block on the frame is limited, and it is difficult to position the clamping block, which easily leads to the risk of the photovoltaic module falling off. Moreover, since the clamping block protrudes in the height direction of the photovoltaic module, it can easily cast a shadow on the photovoltaic module, affecting the power generation efficiency of the photovoltaic module. In addition, since the clamping block needs to be fixed with screws, additional fastening tools are required, resulting in low on-site installation efficiency. Summary of the Invention

(Refer to...) Figure 2 , showed Figure 1 The diagram shows another angle of the structure, for reference. Figure 3 , showed Figure 2 The exploded structural diagram shown is for reference.

Figure 7 , showed Figure 1 A schematic diagram of another frame structure in the photovoltaic installation structure is shown below. Figure 8 , showed Figure 1A schematic diagram of another type of frame in the photovoltaic installation structure described above.

[0026] In this embodiment of the application, the photovoltaic installation structure may specifically include: a frame 10, which can be used to connect to the edge of the photovoltaic laminate 50. The frame 10 has a groove 111 on the side away from the photovoltaic laminate 50, and the groove 111 extends along the length direction of the frame 10. The sliding connector 20 includes a mounting part 201 and a sliding part 202 that are connected to each other. The sliding part 202 is slidably connected in the slide groove 111, and the mounting part 201 is provided with a connection hole 203. In the case where the frames 10 of two photovoltaic laminates 50 are arranged adjacently, each frame 10 is connected to a sliding connector 20, and the mounting parts 201 of the two sliding connectors 20 are adjacent, and the connection holes 203 on the two adjacent mounting parts 201 are aligned. And a connector 30, which passes through the connection holes 203 on two adjacent mounting portions 201 in sequence to connect two adjacent sliding connectors 20.

[0027] In this embodiment, a groove 111 is provided on the side of the frame 10 away from the photovoltaic laminate 50, and a mounting part 201 and a sliding part 202 are provided on the sliding connector 20. The sliding part 202 is slidably connected within the groove 111, and a connecting hole 203 is provided on the mounting part 201. When the frames 10 of two photovoltaic laminates 50 are arranged adjacently, the sliding parts 202 of the two sliding connectors 20 are slidably connected within the grooves 111 of the two frames 10 respectively, and the mounting parts 201 of the two sliding connectors 20 are adjacent, with the connecting holes 203 on the two adjacent mounting parts 201 aligned. Then, the connector 30 is passed through the connecting holes 203 on the two adjacent mounting parts 201 in sequence to connect the two adjacent sliding connectors 20. Thus, the connection between the two adjacent frames 10 connected by the two sliding connectors 20 is realized. Finally, the connection between the two adjacent photovoltaic laminates 50 is realized. The photovoltaic mounting structure described in this embodiment of the invention offers a simple installation method, avoiding the need for on-site screw tightening with fastening tools and significantly improving the installation efficiency of photovoltaic modules. Furthermore, since the sliding portion 202 of the sliding connector 20 is embedded within the groove 111, the connection between the sliding connector 20 and the frame 10 is more reliable, reducing the risk of module detachment. In addition, by avoiding the sliding connector 20 protruding from the photovoltaic module, shadows are prevented on the photovoltaic module, which is beneficial for improving the power generation efficiency of the photovoltaic module.

[0028] like Figures 6 to 8As shown, the main structure of the frame 10 may specifically include a first frame horizontal plate 101 and a second frame horizontal plate 102 arranged at relatively intervals, and a first frame vertical plate 103 and a second frame vertical plate 104 arranged at relatively intervals. The first frame horizontal plate 101 is located above, and the second frame horizontal plate 102 is located below. The two ends of the first frame vertical plate 103 and the second frame vertical plate 104 are respectively connected to the first frame horizontal plate 101 and the second frame horizontal plate 102. The first frame horizontal plate 101, the second frame horizontal plate 102, the first frame vertical plate 103, and the second frame vertical plate 104 enclose a corner bracket cavity 110, which can be used to install and connect frame corner brackets. The top of the first frame horizontal plate 101 may also be provided with a mounting groove 109, which can be used to install the photovoltaic laminate 50. Above the mounting groove 109 is an overflow groove 108, which can be used to contain structural adhesive.

[0029] In this embodiment, at least a portion of the second frame vertical plate 104 is recessed towards the corner bracket cavity 110 to form a groove 111, which can extend along the length of the frame 10. The sliding portion 202 of the sliding connector 20 can be inserted into the groove 111 from its end and slide along the groove 111. When the frames 10 of two photovoltaic laminates 50 are arranged adjacently, the sliding portions 202 of the two sliding connectors 20 can be slid to the position where the connecting holes 203 on the two adjacent mounting portions 201 are aligned. Finally, the connector 30 is passed through the connecting holes 203 on the two adjacent mounting portions 201 in sequence to connect the two adjacent sliding connectors 20. Thus, the connection of the two adjacent frames 10 connected by the two sliding connectors 20 is realized. Finally, the connection between the two adjacent photovoltaic laminates 50 is realized. The installation method is simple, avoiding the operation of tightening screws with fastening tools on site, and greatly improving the installation efficiency of photovoltaic modules.

[0030] like Figure 6 As shown, a frame hook 107 is also provided at the bottom of the frame 10. At least a portion of the frame hook 107 extends into the groove of the photovoltaic bracket 40 to achieve the connection between the frame 10 and the photovoltaic bracket 40. In practical applications, when the frame 10 needs to be connected to the photovoltaic bracket 40, it can be selected... Figure 6 The border shown is 10.

[0031] Optionally, the frame hook 107 may include: a vertically arranged extension plate 105 and a horizontally arranged limiting plate 106. The extension plate 105 is connected to the bottom of the frame 10, and one end of the limiting plate 106 is connected to the extension plate 105, while the other end is suspended. The connection between the limiting plate 106 and the extension plate 105 can form the frame hook 107.

[0032] Specifically, the limiting plate 106 and the second frame horizontal plate 102 can be distributed at relative intervals, and the extension plate 105 is connected between the end of the second frame horizontal plate 102 and the end of the limiting plate 106.

[0033] It should be noted that the accompanying drawings of this application embodiment only show the photovoltaic bracket 40 as a "C"-shaped bracket. Correspondingly, the frame hook 107 has a vertically arranged extension plate 105 and a horizontally arranged limiting plate 106, so that the shape of the frame hook 107 matches the shape of the photovoltaic bracket 40, improving the reliability of the connection between the two. In practical applications, the shape of the frame hook 107 can be set according to the actual shape of the photovoltaic bracket 40 to achieve a reliable connection between the two. The specific shape of the frame hook 107 is not limited in this application embodiment.

[0034] like Figure 7 As shown, a vertically arranged limiting baffle 112 is also provided at the bottom of the frame 10. The limiting baffle 112 can be used to abut against the photovoltaic bracket 40 to prevent the frame 10 from sliding downward and to play a limiting role.

[0035] In practical applications, the photovoltaic laminate 50 is typically a rectangular laminate. Correspondingly, the photovoltaic module comprised of the photovoltaic laminate 50 and the frame 10 typically includes a long side and a short side. The photovoltaic support 40 is typically positioned along its long side. Therefore, along the long side of the photovoltaic module, the frame 10 of the photovoltaic module usually needs to be connected to the photovoltaic support 40.

[0036] like Figure 4 As shown, along the long side of the photovoltaic module, since the photovoltaic module needs to be connected to the photovoltaic support 40, it is possible to select... Figure 6 and Figure 7 The border 10 shown is used in pairs, adjacent to each other. Specifically, Figure 6 The frame hook 107 of the shown frame 10 can extend from the opening of the photovoltaic bracket 40 into the photovoltaic bracket 40 and engage with one side of the opening. Figure 7 The limiting baffle 112 of the frame 10 shown can be used to abut against the other side of the opening of the photovoltaic bracket 40 to prevent the frame 10 from sliding downwards, thus serving as a limiting function. Normally, Figure 6 The border 10 shown and Figure 7 The border 10 shown can usually be used in pairs.

[0037] Figure 8 Another form of the border 10 according to an embodiment of this application is shown. Figure 6 , Figure 7 Compared to the border 10 shown, Figure 8 The shown border 10 has neither a border hook 107 nor a border baffle. For example... Figure 5 As shown, when a direct connection to the photovoltaic bracket 40 is not required, one can choose... Figure 8 The frame 10 shown is connected to the photovoltaic laminate 50.

[0038] Reference Figure 9 This diagram illustrates a connection structure of a sliding connector and a connector according to an embodiment of this application. (Refer to...) Figure 10 , showed Figure 9 The diagram shows an exploded view of the connection structure. (See attached diagram.) Figure 10 As shown, the mounting part 201 may include a mounting plate 2011 and a connecting plate 2012 arranged at a preset angle. The connecting plate 2012 is connected to the mounting plate 2011 and the sliding part 202 respectively. A first opening is provided on the slide groove 111, and the connecting plate 2012 passes through the first opening.

[0039] In specific applications, the mounting portion 201 may include a mounting plate 2011 and a connecting plate 2012 arranged at a preset angle, with the connecting plate 2012 connected to both the mounting plate 2011 and the sliding portion 202. When the sliding portion 202 is embedded in the slide groove 111, the connecting plate 2012 can pass through a first opening in the slide groove 111. Correspondingly, the connecting plate 2012 can slide along the first opening, thereby enabling the sliding connector 20 to slide as a whole along the slide groove 111 for position adjustment.

[0040] Optionally, the frame 10 may include a first side and a second side that are opposite to each other; wherein, the frame 10 is provided with a mounting groove 109, which can be used to install on the edge of the photovoltaic laminate 50, and the mounting groove 109 is provided with a second opening for the photovoltaic laminate 50 to pass through, the second opening facing the first side; the first opening on the slide groove 111 faces the second side.

[0041] In practical applications, since the first opening and the second opening face opposite directions, the photovoltaic laminate 50 and the sliding connector 20 can be connected to the frame 10 from different sides of the frame 10. This not only avoids interference between the sliding connector 20 and the photovoltaic laminate 50, improving the ease of photovoltaic module installation, but also makes the layout of the entire photovoltaic installation structure more compact, reducing the volume of the photovoltaic installation structure.

[0042] In some alternative embodiments of this application, the connector 30 can be a ring structure with an opening, wherein one end of the opening passes through the connecting hole 203 on two adjacent mounting portions 201 respectively to connect two adjacent sliding connectors 20.

[0043] In practical applications, when the connecting holes 203 on two adjacent mounting portions 201 are aligned, the opening of the annular structure can be first oriented upwards, with one end of the opening inserted through the connecting hole 203. The annular structure is then released when the center point of the annular structure and the common center line between the adjacent sliding connectors 20 are aligned. At this point, due to the weight of the annular structure, the opening automatically flips downwards. The annular structure will not detach under external force, thus achieving a reliable connection between adjacent sliding connectors 20 through a simple structure.

[0044] It should be noted that, in practical applications, the shape of the connecting hole 203 may include, but is not limited to, a circle, a square, or other polygons. Correspondingly, the cross-sectional shape of the connector 30 may be a circle, a square, or other polygonal shapes. This application embodiment does not specifically limit the shape of the connecting hole 203 or the cross-sectional shape of the connector 30.

[0045] Optionally, the photovoltaic mounting structure may further include a limiting member 60, which is connected to the bottom of the slide groove 111 and extends at least partially into the slide groove 111 to limit the position of the sliding part 202. In this way, after installation, the sliding connector 20 can be prevented from continuing to slide along the frame 10, thereby improving the connection reliability of the sliding connector 20 on the frame 10.

[0046] Specifically, the sliding part 202 of the sliding connector 20 can be inserted into the slide groove 111 through the end opening of the slide groove 111 on the frame 10. By sliding the sliding part 202 in the slide groove 111, the sliding connector 20 can be slid to the desired target position. Then, the limiting member 60 is used to fix it on both sides of the sliding connector 20, which plays a limiting role and improves the connection reliability of the sliding connector 20 on the frame 10.

[0047] For example, the limiting member 60 can be two screws disposed on both sides of the sliding connector 20, or the limiting member 60 can also be a limiting block protruding from the bottom of the slide groove 111, etc. The specific form of the limiting member 60 is not limited in the embodiments of this application.

[0048] Optionally, a buffer layer (not shown in the figure) is also provided on the side of the limiting member 60 near the sliding part 202. The buffer layer can prevent the limiting member 60 from directly contacting the sliding connector 20, and serves to prevent noise and bimetallic corrosion.

[0049] For example, the buffer layer can be a sealant layer formed after applying weather-resistant sealant, or the buffer layer can be a foam layer, etc. The specific content of the buffer layer is not limited in the embodiments of this application.

[0050] It should be noted that in specific applications, the limiting component 60 and the buffer layer can be manufactured in the factory to avoid on-site processing of the limiting component 60 and the buffer layer, thus achieving the purpose of quick installation.

[0051] Optionally, the photovoltaic mounting structure may further include: flexible gaskets 70, which are respectively disposed between the frame 10 and the photovoltaic bracket 40, and between the mounting portions 201 of two adjacent sliding connectors 20. This achieves isolation between the frame 10 and the photovoltaic bracket 40, and between the mounting portions 201 of the two adjacent sliding connectors 20, thereby serving the purposes of noise prevention, prevention of bimetallic corrosion, and adaptation to stress deformation.

[0052] In practical applications, the frame 10, photovoltaic bracket 40, and sliding connector 20 are typically made of metal. If the frame 10 is in direct contact with the photovoltaic bracket 40, or if the mounting portions 201 of two adjacent sliding connectors 20 are in direct contact, chemical reactions such as rust will occur between the frame 10 and the photovoltaic bracket 40, and between the two adjacent mounting portions 201, when exposed to water or other media. This results in bimetallic corrosion, affecting the service life of the frame 10, photovoltaic bracket 40, and sliding connector 20. In this embodiment, by providing flexible gaskets 70 between the frame 10 and the photovoltaic bracket 40, and between the mounting portions 201 of two adjacent sliding connectors 20, a barrier function can be established, preventing bimetallic corrosion caused by direct contact between the frame 10 and the photovoltaic bracket 40, and between the mounting portions 201 of two adjacent sliding connectors 20.

[0053] For example, the flexible gasket 70 can be made of flexible materials such as rubber, silicone and foam. In this embodiment of the application, the specific material of the flexible gasket 70 is not limited.

[0054] Reference Figure 11 This illustration shows a schematic diagram of another photovoltaic installation structure according to an embodiment of this application, installed on a photovoltaic building. Figure 11 As shown, for photovoltaic modules located on the side of a photovoltaic system, one end is fixedly connected to an adjacent photovoltaic module via a sliding connector 20, and the other end is fixedly connected to an edge connector 80. The edge connector 80 simply replaces the sliding groove 111 structure of the connection structure on the side without module installation with a C-shaped structure. The C-shaped structure directly engages with the side wall and bottom of the photovoltaic guide rail. The edge connector 80 and the sliding connector 20 are still connected via a connector 30.

[0055] In some optional embodiments of this application, the photovoltaic mounting structure may further include a limiting block 90, which can be fixed at the center of the cross joint of the photovoltaic module and reliably connected to the photovoltaic bracket 40 by bolts.

[0056] Reference Figure 12 The diagram shows a structural schematic of a limiting block according to an embodiment of this application, as shown below. Figure 12 As shown, the limiting block 90 may include a first baffle 901 and a second baffle 902 disposed opposite to each other, and an intermediate plate 903 connecting the first baffle 901 and the second baffle 902. The contact surfaces between the first baffle 901, the second baffle 902, and the intermediate plate 903 and the photovoltaic support 40 can be insulated with soft insulating gaskets to prevent noise, prevent bimetallic corrosion, and accommodate stress deformation. Specifically, the intermediate plate 903 may also be provided with through holes 904 for bolt insertion.

[0057] In practical applications, the limiting block 90 and the photovoltaic support 40 are typically made of metal. If the first baffle 901, the second baffle 902, and the intermediate plate 903 of the limiting block 20 are in direct contact with the photovoltaic support 40, chemical reactions such as rust will occur between the limiting block 90 and the photovoltaic support 40 when exposed to media such as water, forming bimetallic corrosion and affecting the service life of both the limiting block 90 and the photovoltaic support. In this embodiment, by providing flexible gaskets between the first baffle 901, the second baffle 902, the intermediate plate 903 and the photovoltaic support 40, a barrier function can be achieved, preventing bimetallic corrosion caused by direct contact between the limiting block 90 and the photovoltaic support 40.

[0058] In summary, the photovoltaic installation structure described in the embodiments of this application may include at least the following advantages: In this embodiment, a groove is provided on the side of the frame away from the photovoltaic laminate, and an mounting part and a sliding part are provided on the sliding connector. The sliding part is slidably connected in the groove, and the mounting part is provided with a connection hole. When the frames of two photovoltaic laminates are arranged adjacently, the sliding parts of the two sliding connectors are slidably connected in the grooves of the two frames respectively, and the mounting parts of the two sliding connectors are adjacent, with the connection holes on the two adjacent mounting parts aligned. Then, the connectors are passed through the connection holes on the two adjacent mounting parts in sequence to connect the two adjacent sliding connectors. Thus, the connection of the two adjacent frames connected by the two sliding connectors is realized. Finally, the connection between the two adjacent photovoltaic laminates is realized. The photovoltaic installation structure described in this embodiment of the invention has a simple installation method, avoids the operation of tightening screws with fastening tools on site, and greatly improves the installation efficiency of photovoltaic modules. Moreover, since the sliding part of the sliding connector is embedded in the groove, the connection between the sliding connector and the frame is more reliable, and the risk of module detachment is not high. Furthermore, by avoiding the operation of sliding connectors protruding on the photovoltaic module, shadows can be avoided on the photovoltaic module, which is beneficial to improving the power generation efficiency of the photovoltaic module.

[0059] This application also provides a photovoltaic building, which may specifically include: a building, a photovoltaic support, a photovoltaic laminate, and a photovoltaic installation structure as described above; wherein, the photovoltaic support is connected to the building; the photovoltaic laminate is connected to the frame of the photovoltaic installation structure, and the frame is connected to the photovoltaic support.

[0060] In this embodiment, the structure of the photovoltaic installation structure in the photovoltaic building is the same as that of the photovoltaic installation structure summarized in the foregoing embodiments, and its beneficial effects are also similar, so it will not be described again here.
