Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, and in particular to a photovoltaic device. Background Technology

[0002] Traditional photovoltaic (PV) modules are mostly installed horizontally or at an angle, which takes up a large area and blocks sunlight. In some installation scenarios, PV modules are limited by space constraints, such as on agricultural land. PV modules should not block sunlight from crops and negatively impact their growth. Vertical installation of PV modules reduces the impact on agricultural activities. Furthermore, vertical installation can also be applied to other "PV+ scenarios" such as highway guardrails and residential fences.

[0003] Prior art document (CN119866597A) discloses a vertical photovoltaic system, which includes at least one photovoltaic module and two columns. For each column, a main fixing device is used to fix a flexible first tension strap to the column, and the cooperation between the main fixing devices applies longitudinal tension to the first tension strap; the flexible first tension strap is tensioned between the two columns; and a fixing device is used to fix the module to the tension strap. During installation, the module needs to be fixed to the tension strap, the tension strap needs to be fixed to the column, and the tension strap also needs to be tensioned, making the installation operation difficult. Utility Model Content

For example, it can be used as a fence for houses, perimeter fences of residential areas, and fences for overpasses. In high-latitude regions of the earth, due to the small angle of direct sunlight, the vertically installed photovoltaic modules have a smaller area of ​​shading sunlight and the surface is less likely to accumulate dust and other dirt, resulting in superior power generation. Since the photovoltaic device of this application adopts vertical installation, it can reduce sunlight shading in agricultural photovoltaic complementary applications and will not occupy too much arable land area, which is conducive to expanding the application scale of photovoltaic modules.

[0008] In some embodiments, the outer contour of the cross-section of the slider perpendicular to its own extension direction includes an arc segment, at least a portion of which is in contact with the inner wall surface of the groove.

[0009] In some embodiments, the slider is a hollow tube.

[0010] In some embodiments, the groove has an opening along the thickness direction of the photovoltaic panel, and the size of the opening is smaller than the maximum size of the slider.

[0011] In some embodiments, the mounting frame further includes a crossbeam and a column, the crossbeam and the column forming an mounting space, the photovoltaic module being disposed in the mounting space, the guide member being formed on the side of the crossbeam near the photovoltaic module, the column being formed with a mounting groove, and the guide member being inserted into the mounting groove.

[0012] In some embodiments, the column and / or the beam are connected to a support on at least one side along the thickness direction of the photovoltaic panel.

[0013] In some embodiments, the mounting member includes two first side beams and two second side beams, the first side beams extending horizontally and having the grooves formed or connected to the sliding members, and the second side beams extending vertically and having their ends respectively connected to the two first side beams.

[0014] In some embodiments, the first side beam has a first slot at both ends, and the second side beam has a second slot at both ends. A connector is inserted into the first slot and the second slot to connect the first side beam and the second side beam.

[0015] In some embodiments, both the first side beam and the second side beam include a frame beam, an extension, and a flange. The frame beam and the flange are spaced apart along the thickness direction of the photovoltaic panel. The extension is connected between the frame beam and the flange. The edge of the photovoltaic panel is located between the frame beam and the flange.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order or hierarchy.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "attachment," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0038] In the embodiments of this utility model, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this utility model shown in the drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this utility model.

[0039] In this utility model, "multiple" refers to two or more (including two).

[0040] The following is combined Figures 1 to 9 The photovoltaic device 100 of this utility model is described below.

[0041] like Figure 1 and Figure 2 As shown, the photovoltaic device 100 according to an embodiment of the present invention includes a photovoltaic module 10 and a mounting frame 20. The photovoltaic module 10 includes a connected photovoltaic panel 101 and a mounting member 102; the mounting frame 20 includes a guide member 201, one of the guide member 201 and the mounting member 102 having a groove 202, and the other of the guide member 201 and the mounting member 102 having a sliding member 103, the sliding member 103 being disposed in the groove 202 and cooperating with the groove 202, the mounting frame 20 being used to mount the photovoltaic module 10 so that the photovoltaic panel 101 is arranged vertically.

[0042] Specifically, the photovoltaic panel 101 may include a front glass panel, a rear glass panel, and solar cells, which may be encapsulated between the front and rear glass panels using an encapsulation material. A mounting bracket 102 is connected to the photovoltaic panel 101 for mounting the photovoltaic panel 101 onto the mounting frame 20.

[0043] For example, you can refer to Figure 2 and Figure 5 The guide member 201 has a groove 202, and the mounting member 102 has a slider 103. Alternatively, the guide member 201 is a slider 103, and the mounting member 102 has a groove 202.

[0044] For example, the slider 103 may extend horizontally and there are two sliders 103, which are spaced apart vertically. Correspondingly, the slide groove 202 also extends horizontally and there are two slide grooves 202, which are spaced apart vertically.

[0045] For example, two sliders 103 may extend vertically and are provided, with the two sliders 103 spaced apart horizontally. Correspondingly, two slide grooves 202 may also extend horizontally and are provided, with the two slide grooves 202 spaced apart horizontally. During installation, the sliders 103 can be installed into the slide grooves 202 from top to bottom. Thus, the frame 20 may not need to have an upper crossbeam 203, or the upper crossbeam 203 may have a smaller volume and strength, thereby reducing the cost of the frame 20.

[0046] According to the photovoltaic device 100 of this utility model embodiment, when installing the photovoltaic module 10, the sliding member 103 is pushed into the sliding groove 202 along the extension direction of the sliding member 103. The installation is convenient and there is no need to open the mounting holes on the mounting frame 20 and the mounting member 102, which helps to reduce the processing cost of the mounting frame 20 and the mounting member 102. At the same time, the mounting frame 20 in this application is used to install the photovoltaic module 10 so that the photovoltaic panel 101 is arranged vertically. Therefore, the photovoltaic device 100 of this application has a small footprint and can be widely used for photovoltaic power generation in densely populated areas. For example, it can be used as a fence for houses, perimeter fences of residential areas, and fences for overpasses. In high-latitude regions of the earth, due to the small angle of direct sunlight, the area of ​​the vertically installed photovoltaic module 10 that blocks sunlight is reduced and the surface is less likely to retain dust and other dirt, resulting in superior power generation. Since the photovoltaic device 100 of this application adopts vertical installation, it can reduce the blocking of sunlight in agricultural photovoltaic complementary applications and will not occupy too much farmland area, which is conducive to expanding the application scale of photovoltaic modules.

[0047] In some embodiments, reference may be made to Figure 3 Two sliding members 103 extend horizontally and are provided, with the two sliding members 103 spaced apart vertically. In this way, during installation, the photovoltaic module 10 can be directly pushed horizontally so that the sliding member 103 enters the slide groove 202, making the installation simple, convenient and labor-saving; at the same time, the constraints on both sides can suppress the lateral swaying of the photovoltaic module 10 during use.

[0048] In some embodiments, reference may be made to Figure 5 The outer contour of the cross-section of the sliding member 103 perpendicular to its extension direction includes an arc-shaped segment 1031. At least a portion of the arc-shaped segment 1031 is in contact with the inner wall surface of the slide groove 202. Correspondingly, the inner wall surface of the slide groove 202 used to mate with the arc-shaped segment 1031 is also arc-shaped. It should be noted that the mounting member 102 and the mounting frame 20 are usually extruded profiles. The outer contour of the cross-section of the sliding member 103 perpendicular to its extension direction includes the arc-shaped segment 1031. In this way, the cost of molding the sliding member 103 and the slide groove 202 is low, and the molding yield is high, which helps to reduce production costs. On the other hand, during use, rainwater, impurities, etc., falling into the slide groove 202 are more easily discharged, which helps to reduce the accumulation of rainwater, impurities, etc. in the slide groove 202.

[0049] For example, the portion of the outer contour of the slider 103 that mates with the inner wall of the slide groove 202 may be entirely an arc segment 1031; or, the portion of the outer contour of the slider 103 that mates with the inner wall of the slide groove 202 may include connected straight segments and arc segments 1031; or, the portion of the outer contour of the slider 103 that mates with the inner wall of the slide groove 202 may only include multiple connected straight segments. All of these should be within the scope of protection of the application.

[0050] In some embodiments, reference may be made to Figure 5 The slider 103 is a hollow tube. This reduces the material and weight of the slider 103 while also giving it high structural strength.

[0051] In some embodiments, reference may be made to Figure 5 The slide 202 has a groove 2021 along the thickness direction of the photovoltaic panel 101, and the size of the groove 2021 is smaller than the maximum size of the sliding member 103.

[0052] In this way, the upper groove 202 can support the sliding member 103, preventing the weight of the photovoltaic module 10 from being entirely concentrated on the lower sliding member 103 and the groove 202. This helps to reduce the structural strength requirements of the sliding members 103 on both sides, and consequently reduces the production cost of the mounting component 102 and the guide component 201. At the same time, the smaller slot 2021 can also prevent larger impurities from entering the groove 202, affecting the sliding of the sliding member 103, and increasing the difficulty of later maintenance and replacement.

[0053] In some embodiments, reference may be made to Figure 1 The mounting frame 20 also includes a crossbeam 203 and a column 204, which enclose an installation space. The photovoltaic module 10 is installed in the installation space, as can be seen from [reference needed]. Figure 2 A guide member 201 is formed on the side of the crossbeam 203 near the photovoltaic module 10, which can be referred to as Figure 6 The column 204 has a mounting groove 2041, and the two ends of the guide member 201 are inserted into the mounting groove 2041.

[0054] Specifically, the crossbeam 203 extends horizontally, and the column 204 extends vertically. A guide member 201 is formed on the side of the crossbeam 203 closest to the photovoltaic module 10; that is, a guide member 201 is formed on the lower side of the upper crossbeam 203, and a guide member 201 is formed on the upper side of the lower crossbeam 203. (See reference...) Figure 6The column 204 has a mounting groove 2041, and the guide 201 is inserted into the mounting groove 2041. In other words, the column 204 and the crossbeam 203 can be connected by inserting the guide 201 into the mounting groove 2041 of the column 204. The connection is convenient and quick, and there is no need to open mounting holes on the column 204 and the crossbeam 203, which helps to reduce processing costs.

[0055] More specifically, along the thickness direction of the photovoltaic module 10, the size of the vertically oriented slot of the mounting groove 2041 can be smaller than the maximum size of the guide member 201, so that the column 204 will not detach from the crossbeam 203 in the vertical direction.

[0056] Understandably, it can be referenced. Figure 1 Both ends of the multiple columns 204 can be connected to two crossbeams 203. The multiple columns 204 are spaced apart along the extension direction of the crossbeams 203 to form multiple installation spaces for accommodating multiple photovoltaic modules 10. Multiple photovoltaic modules 10 can be installed between two columns 204, or only one photovoltaic module 10 can be installed.

[0057] In some embodiments, a support 205 is connected to one side of the column 204 along the thickness direction of the photovoltaic panel 101. In some embodiments, reference can be made to... Figure 1 The support column 204 is connected to the support bracket 205 on both sides along the thickness direction of the photovoltaic panel 101. In some embodiments, the crossbeam 203 is connected to the support bracket 205 on one side along the thickness direction of the photovoltaic panel 101. In some embodiments, the crossbeam 203 is connected to the support bracket 205 on both sides along the thickness direction of the photovoltaic panel 101.

[0058] The bracket 205 can be designed according to requirements. In some embodiments, the bracket 205 can be used to mount the photovoltaic device 100 onto an external object, such as a wall; in other embodiments, the bracket 205 can be designed to stably and independently place the photovoltaic device 100 on a horizontal mounting surface. Alternatively, the bracket 205 can be used to connect the column 204 and the beam 203 to fix the relative positions of the column 204 and the beam 203.

[0059] In some embodiments, reference may be made to Figure 7 The mounting component 102 includes two first side beams 1021 and two second side beams 1022. The first side beams 1021 extend horizontally and are formed with a groove 202 or connected to a sliding member 103. The second side beams 1022 extend vertically and are connected to the two first side beams 1021 at both ends respectively.

[0060] On the one hand, the first side beam 1021 and the second side beam 1022 can protect the photovoltaic panel 101, reducing the possibility of damage to the edges of the photovoltaic panel 101 due to accidental impact. On the other hand, the first side beam 1021 and the second side beam 1022 can provide additional mechanical protection for the photovoltaic panel 101, increasing its overall structural strength and rigidity, making it more resistant to the influence of the external environment, such as wind pressure and snow load. The first side beam 1021 extends horizontally, and the second side beam 1022 extends vertically, meaning that the photovoltaic panel 101 is rectangular. This facilitates the compact arrangement of the photovoltaic panel 101 and improves space utilization efficiency.

[0061] In some embodiments, reference may be made to Figure 8 The first side beam 1021 has a first slot at both ends, and the second side beam 1022 has a second slot at both ends. The connector 104 is inserted into the first slot and the second slot to connect the first side beam 1021 and the second side beam 1022.

[0062] For example, the connector 104 can be a corner bracket. Using the connector 104 to connect the first side beam 1021 and the second side beam 1022 is simple and convenient, and allows for better control of the arrangement angle of the first side beam 1021 and the second side beam 1022. In embodiments where the connector 104 is a corner bracket, a universal component is used to connect the first side beam 1021 and the second side beam 1022, thereby helping to reduce the production cost of the photovoltaic module 10.

[0063] In some embodiments, reference may be made to Figure 9 The first side beam 1021 and the second side beam 1022 both include a frame beam 1023, an extension 1024 and a flange 1025. The frame beam 1023 and the flange 1025 are spaced apart along the thickness direction of the photovoltaic panel 101. The extension 1024 is connected between the frame beam 1023 and the flange 1025. The edge of the photovoltaic panel 101 is located between the frame beam 1023 and the flange 1025.

[0064] Here, the frame beam 1023 ensures that the first side beam 1021 and the second side beam 1022 have high structural strength while also minimizing their mass. The edge of the photovoltaic panel 101 is located between the frame beam 1023 and the flange 1025. The gaps between the photovoltaic panel 101 and the frame beam 1023 and the flange 1025 can be sealed with sealant, which effectively prevents moisture, dust, and other contaminants from entering the interior of the photovoltaic panel 101, thus improving the weather resistance and service life of the photovoltaic panel 101.

[0065] In some embodiments, the relative position between the photovoltaic module 10 and the mounting frame 20 can be fixed by applying adhesive between them. Alternatively, the relative position between the photovoltaic module 10 and the mounting frame 20 can be fixed by an interference fit between the slider 103 and the groove 202. Alternatively, clamps can be directly installed on the guide members 201 on both sides of the photovoltaic module 10 to limit the position of the photovoltaic module 10, making it difficult for the photovoltaic module 10 to slip relative to the mounting frame 20 after installation.

[0066] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0067] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
