Description

Technical Field

[0001] This application relates to the field of photovoltaic module installation technology, and more specifically, to a fastener and a photovoltaic power generation system. Background Technology

[0002] In a photovoltaic power generation system, photovoltaic modules are installed on photovoltaic supports, such as flexible photovoltaic supports.

[0003] In related technologies, connectors are fixed on photovoltaic brackets, and the frame of the photovoltaic module is fixedly connected to the connectors by fasteners to achieve the installation of the photovoltaic module.

[0004] During installation, after the photovoltaic (PV) modules are placed on the PV support frame, installers need to manually support the modules to prevent them from slipping. They also need to install fasteners to secure the modules and connectors. This manual support hinders the installation process, resulting in low installation efficiency. Utility Model Content

[0005] In view of this, this application provides a fastener and a photovoltaic power generation system to improve the installation efficiency of photovoltaic modules.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A fastener, comprising:

[0008] A first clamping plate and a second clamping plate are connected to form a clamping groove. The first clamping plate and the second clamping plate are distributed along a first direction. The opening and bottom of the clamping groove are opposite each other along a second direction. The clamping groove is deformable and is used to accommodate the component mounting parts of the photovoltaic bracket.

[0009] A first connecting plate has a first end and a second end. The first end is connected to the end of the first clamping plate that is away from the bottom of the groove along the second direction. The second end is farther away from the first clamping plate along the second direction than the first end, and farther away from the clamping groove along the first direction than the first end. The first connecting plate is used to fixally connect to the bottom edge of the component frame. The second direction is perpendicular to the first direction.

[0010] The first clamping plate and the second clamping plate are both used to fix and connect to the bottom edge, and to deform the clamping groove and clamp the component mounting piece.

[0011] In some possible embodiments, the first connecting plate is provided with a meshing groove for meshing with the bottom edge; the meshing groove opening faces the first connecting plate along a third direction, and both the first direction and the second direction are perpendicular to the third direction.

[0012] In some possible embodiments, at least one of the first connecting plate and the bottom edge can deform to engage the engagement groove with the bottom edge.

[0013] In some possible embodiments, the first connecting plate includes a first portion and a second portion, the first portion connecting one end of the second portion along the third direction to the first clamping plate, the interlocking groove being distributed between the first portion and the second portion, the length of the second portion along the third direction being less than the length of the first portion along the third direction, and the other end of the second portion along the third direction being used to abut against the side edge of the component frame along the third direction.

[0014] In some possible embodiments, the second clamping plate can deform to allow the clamping groove to deform.

[0015] In some possible embodiments, the second clamping plate includes a clamping plate body and a clamping plate connecting portion;

[0016] The clamp connecting portion and the clamp body are distributed along the second direction. The clamp body is connected to the first clamp. The clamp connecting portion has a first clamp end and a second clamp end. The first clamp end is connected to the clamp body. The second clamp end is farther away from the first clamp in the first direction than the first clamp end.

[0017] The clamping plate connecting part is used for fixed connection with the bottom edge.

[0018] In some possible embodiments, the first clamp and the second clamp are used to securely connect to the bottom edge by the same fastener.

[0019] In some possible embodiments, the fastener further includes a second connecting plate;

[0020] The second connecting plate is connected to one end of the first clamping plate along the third direction, and the second connecting plate and the first connecting plate are located on one side of the first clamping plate along the first direction;

[0021] The second connecting plate and the first clamping plate form a receiving groove, which is used to receive the bottom edge. The receiving groove opening faces the side of the first clamping plate along the third direction; both the first direction and the second direction are perpendicular to the third direction.

[0022] The second connecting plate is used for fixed connection with the bottom edge.

[0023] In some possible embodiments, the fastener further includes a pressure block, the base plate of which is located between the bottom edge and the first clamping plate, and the receiving groove is also used to receive the base plate.

[0024] In some possible embodiments, the first clamping plate, the second clamping plate, and the second connecting plate are used to securely connect to the bottom edge by the same fastener.

[0025] In some possible embodiments, the second clamping plate or the second connecting plate is provided with threaded holes that mate with the fastener.

[0026] In some possible embodiments, the fastener further includes a nut forming the threaded hole, the nut being fixed to the second clamping plate or the second connecting plate where the threaded hole is located.

[0027] In some possible embodiments, the first clamping plate, the second clamping plate, the first connecting plate, and the second connecting plate are an integral structure.

[0028] Based on the fasteners provided above, this application also provides a photovoltaic power generation system, which includes: a photovoltaic module, a photovoltaic bracket, and the fasteners described in any of the above embodiments, wherein the fasteners are fixedly connected to the bottom edge of the photovoltaic module and the component mounting parts of the photovoltaic bracket.

[0029] In some possible embodiments, the photovoltaic support is a flexible photovoltaic support, and the component mounting element is a cable.

[0030] In some possible embodiments, the photovoltaic module is fixedly connected to the same cable body on both sides along a third direction by the fasteners, wherein the first direction and the second direction are both perpendicular to the third direction;

[0031] And / or, at least two of the cables distributed along the second direction are fixedly connected to the same photovoltaic module by the fastener, the second direction and the vertical direction being inclinedly distributed.

[0032] The method of using the fastener provided in this application includes:

[0033] The connection between the first connecting plate and the bottom edge of the component frame realizes the connection between the fastener and the bottom edge; since the first end of the first connecting plate is connected to the end of the first clamping plate away from the bottom of the groove along the first direction, and the second end of the first connecting plate is away from the first clamping plate and away from the clamping groove along the first direction, and the first clamping plate and the second clamping plate are distributed along the first direction, the first clamping plate and the second clamping plate can be located on one side of the bottom edge along the first direction, and the first connecting plate can be located on the other side of the bottom edge along the first direction;

[0034] The photovoltaic module with fixing parts is placed on the photovoltaic bracket, and the first clamp and the second clamp are connected to form a groove to accommodate the module mounting parts of the photovoltaic bracket. The groove opening and the groove bottom are opposite to each other along the second direction. In this way, the photovoltaic module with fixing parts can be hung on the module mounting parts.

[0035] The first clamping plate, the second clamping plate, and the bottom edge are fixedly connected, so that both the first clamping plate and the second clamping plate are fixedly connected to the base plate. During the fixed connection process, the clamping groove deforms, so that the clamping groove clamps the component mounting part, thereby also realizing the fixed connection between the fixing part and the photovoltaic bracket, and then realizing the fixed connection between the photovoltaic module and the photovoltaic bracket, thus completing the installation of the photovoltaic module.

[0036] As can be seen from the above usage method, the fastener can be pre-connected to the bottom edge of the photovoltaic module through the first connecting plate. The clamping groove of the fastener can hang the photovoltaic module with the fastener on the module mounting part of the photovoltaic bracket. The first clamping plate and the second clamping plate of the fastener are both fixedly connected to the bottom edge, which can realize the deformation of the clamping groove and clamp the module mounting part, thereby realizing the fixed connection between the fastener and the photovoltaic bracket, and then the fixed connection between the photovoltaic module and the photovoltaic bracket, thus completing the installation of the photovoltaic module. Moreover, since the photovoltaic module and the first connecting plate can be pre-connected, after the photovoltaic module with the fastener is hung on the module mounting part, the probability of the photovoltaic module slipping can be reduced, and there is no need to manually support the photovoltaic module. This makes it easier for the installer to fix the first clamping plate and the second clamping plate to the bottom edge, which can effectively improve the installation efficiency of the photovoltaic module.

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, “one or more” means one, two, or more; “and / or” describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0075] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0076] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0077] The terms "parallel" and "perpendicular" used in this application refer to "basically parallel" and "basically perpendicular" in practical operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0078] In photovoltaic (PV) power generation systems, PV modules are mounted on PV support structures, such as flexible PV brackets. In related technologies, connectors are fixed to the PV support, and the frame of the PV module is fixed to the connectors using fasteners to achieve the installation of the PV module. This installation structure has relatively low PV module installation efficiency.

[0079] To address the aforementioned issues, this application provides a fastener and a photovoltaic power generation system to improve the installation efficiency of photovoltaic modules.

[0080] To facilitate understanding of this solution, the photovoltaic power generation system provided in the embodiments of this application will be described below.

[0081] like Figure 1 As shown, the photovoltaic power generation system provided in this application embodiment includes: a fixing component 1, a photovoltaic module 2, and a photovoltaic support 3. The fixing component 1 is used to fix the photovoltaic module 2 and the module mounting component 301 of the photovoltaic support 3.

[0082] like Figure 2 As shown, the photovoltaic module 2 includes a photovoltaic panel 201 and a module frame 202. The module frame 202 includes a bottom edge 2021, a frame body 2022, and a side edge 2023. The frame body 2022, side edge 2023, and bottom edge 2021 are distributed along a first direction. The side edge 2023 connects the frame body 2022 and the bottom edge 2021. The photovoltaic panel 201 is disposed on the frame body 2022, and the frame body 2022 surrounds the edge of the photovoltaic panel 201. The bottom edge 2021 can also be referred to as the C-edge.

[0083] like Figure 3 and Figure 4 As shown, the fastener 1 securely connects the bottom edge 2021 of the component frame 202 and the component mounting part 301.

[0084] In this embodiment, the photovoltaic support 3 can be a rigid support, and the module mounting component 301 can be a support beam. The photovoltaic support 3 can also be a flexible photovoltaic support, and the module mounting component 301 can be a cable 301a. The cable 301a can be steel strand, steel wire rope, stainless steel cable, or other types.

[0085] In photovoltaic power generation systems, photovoltaic modules can be arranged at an angle relative to the horizontal direction to improve power generation efficiency. Of course, photovoltaic modules can also be arranged parallel to the horizontal direction.

[0086] The following describes in detail the fastener 1 provided in the embodiments of this application.

[0087] Please refer to Figure 5 The fasteners provided in this application embodiment include: a first clamping plate 101, a second clamping plate 102, and a first connecting plate 103.

[0088] The first clamping plate 101 and the second clamping plate 102 are connected to form a clamping groove 106. The first clamping plate 101 and the second clamping plate 102 are distributed along the first direction. The groove opening 1062 and the groove bottom 1061 of the clamping groove 106 are opposite each other along the second direction. The clamping groove 106 is deformable.

[0089] It should be noted that the clamping groove 106 is a through groove, and the clamping groove 106 can be U-shaped or other shapes. The first clamping plate 101 and the second clamping plate 102 can be directly connected to form the clamping groove 106, or the first clamping plate 101 and the second clamping plate 102 can be indirectly connected to form the clamping groove 106.

[0090] Please refer to Figure 4 The groove 106 is used to accommodate the component mounting part 301 of the photovoltaic bracket 3.

[0091] Please refer to Figure 6 The first connecting plate 103 has a first end 1033 and a second end 1034. The first end 1033 of the first connecting plate 103 is connected to the end of the first clamping plate 101 that is away from the bottom of the groove 1061 along a second direction. The second end 1034 of the first connecting plate 103 is further away from the first clamping plate 101 along the second direction than the first end 1033, and the second end 1034 of the first connecting plate 103 is further away from the clamping groove 106 along a first direction than the first end 1033. The first direction is perpendicular to the second direction.

[0092] It should be noted that when both the first clamping plate 101 and the first connecting plate 103 are flat, the first clamping plate 101 and the first connecting plate 103 are inclined.

[0093] Please refer to Figure 4 The first connecting plate 103 is used to connect to the bottom edge 2021 of the module frame 202. In some embodiments, to facilitate the installation of the photovoltaic module 2, the first connecting plate 103 is fixedly connected to the bottom edge 2021 of the module frame 202. In other embodiments, the first connecting plate 103 and the bottom edge 2021 of the module frame 202 can be movably connected. It is understood that the first connecting plate 103 can move relative to the bottom edge 2021, and the first connecting plate 103 and the bottom edge 2021 are not separated.

[0094] Please refer to the embodiments in this application. Figure 4 Both the first clamping plate 101 and the second clamping plate 102 are used to fix and connect to the bottom edge 2021, and deform the clamping groove 106 to clamp the component mounting piece 301.

[0095] For example, comparison Figure 13 and Figure 15 It can be seen that during the process of fixing both the first clamping plate 101 and the second clamping plate 102 to the bottom edge 2021, the clamping groove 106 can deform; for example Figure 15As shown, with both the first clamping plate 101 and the second clamping plate 102 fixedly connected to the bottom edge 2021, the deformed clamping groove 106 clamps the component mounting piece 301, thus achieving a fixed connection between the clamping groove 106 and the component mounting piece 301.

[0096] The method of using the above-mentioned fastener 1 includes:

[0097] The first connecting plate 103 and the bottom edge 2021 of the component frame 202 are connected to achieve a fixed connection between the fastener 1 and the bottom edge 2021. Since the first end 1033 of the first connecting plate 103 is connected to the end of the first clamping plate 101 that is away from the bottom of the groove 1061 along the second direction, the second end 1034 of the first connecting plate 103 is away from the first clamping plate 101 along the second direction than the first end 1033, and the second end 1034 of the first connecting plate 103 is away from the clamping groove 106 along the first direction than the first end 1033. The first clamping plate 101 and the second clamping plate 102 are distributed along the first direction. Therefore, the first clamping plate and the second clamping plate can be located on one side of the bottom edge 2021 along the first direction, and the first connecting plate 103 can be located on the other side of the bottom edge 2021 along the first direction.

[0098] The photovoltaic module 2 with the fixing member 1 is placed on the photovoltaic bracket 3, and the first clamping plate 101 and the second clamping plate 102 are connected to form a clamping groove 106 to accommodate the component mounting part 301 of the photovoltaic bracket 3. The groove opening 1062 and the groove bottom 1061 of the clamping groove 106 are opposite to each other in the second direction. In this way, the photovoltaic module 2 with the fixing member 1 can be hung on the component mounting part 301.

[0099] The first clamping plate 101, the second clamping plate 102 and the bottom edge 2021 are fixedly connected, so that the first clamping plate 101 and the second clamping plate 102 are both fixedly connected to the bottom edge 2021. During the fixed connection process, the clamping groove 106 clamps the component mounting part 301, thereby also realizing the fixed connection between the fixing part 1 and the photovoltaic bracket 3, and then realizing the fixed connection between the photovoltaic module 2 and the photovoltaic bracket 3, thus completing the installation of the photovoltaic module 2.

[0100] As described above, the fixing component 1 can be pre-connected to the bottom edge 2021 of the photovoltaic module 2 via the first connecting plate 103. The photovoltaic module 2 with the fixing component 1 can be hung on the module mounting component 301 of the photovoltaic bracket via the clamping groove 106. The first clamping plate 101 and the second clamping plate 102 of the fixing component 1 are both fixedly connected to the bottom edge 2021, which allows the clamping groove 106 to deform and clamp the module mounting component 301, thereby achieving a fixed connection between the fixing component 1 and the photovoltaic bracket 3, and further achieving a fixed connection between the photovoltaic module 2 and the photovoltaic bracket 3, thus completing the installation of the photovoltaic module 2. Moreover, since the photovoltaic module 2 and the fixing component 1 can be pre-connected, the photovoltaic module 2 with the fixing component 1, after being hung on the module mounting component 301, can reduce the probability of the photovoltaic module 2 slipping off, eliminating the need for manual support of the photovoltaic module 2. This facilitates the installation personnel in completing the fixed connection of the first clamping plate 101 and the second clamping plate 102 to the bottom edge 2021, effectively improving the installation efficiency of the photovoltaic module 2.

[0101] The fastener 1 provided in this application embodiment eliminates the need for manual support of the photovoltaic module 2 during installation, thereby reducing the number of installers and lowering the labor costs required for installing the photovoltaic module 2.

[0102] The fastener 1 provided in this application embodiment can be pre-installed on the photovoltaic module 2. This pre-installation is a low-altitude installation, which simplifies the installation compared to high-altitude installation and helps to improve installation efficiency. It also reduces the workload of high-altitude installation, which helps to reduce installation costs and also helps to reduce the risk of safety accidents caused by high-altitude installation.

[0103] In this embodiment, the specific structure connecting the first connecting plate 103 and the bottom edge 2021 is selected according to the actual situation. In some embodiments, the first connecting plate 103 is fixedly connected to the bottom edge 2021 by threaded connectors or other fasteners. In this case, additional mounting holes need to be provided on the bottom edge 2021.

[0104] In some other embodiments, the first connecting plate 103 is fixedly connected to the bottom edge 2021 by welding.

[0105] In some other embodiments, such as Figure 6 As shown, the first connecting plate 103 is provided with a bite groove 107. The bite groove opening 1073 of the bite groove 107 faces the first connecting plate 103 along the third direction. The first direction and the second direction are both perpendicular to the third direction.

[0106] It should be noted that the occlusal groove 107 is a through groove.

[0107] Please refer to Figure 4The engagement groove 107 is used to engage with the bottom edge 2021. In this way, the first connecting plate 103 and the bottom edge 2021 can be snapped together, which facilitates the installation of the first connecting plate 103 and the bottom edge 2021.

[0108] In some embodiments, the engagement groove 107 can be deformed. It is understood that the first connecting plate 103 can deform to allow the engagement groove 107 and the bottom edge 2021 to engage. Thus, during the installation of the first connecting plate 103 and the bottom edge 2021, the engagement groove 107 can deform, facilitating engagement between the engagement groove 107 and the bottom edge 2021, while simultaneously increasing the engagement force of the engagement groove 107 and improving the connection strength between the first connecting plate 103 and the bottom edge 2021.

[0109] In some other embodiments, the bottom edge 2021 can deform to allow the engagement groove 107 and the bottom edge 2021 to engage. Thus, during the installation of the first connecting plate 103 and the bottom edge 2021, the bottom edge 2021 can deform, facilitating the engagement of the engagement groove 107 and the bottom edge 2021, while also increasing the engagement force of the engagement groove 107, thereby improving the connection strength between the first connecting plate 103 and the bottom edge 2021.

[0110] Figure 8 The method of connecting the first connecting plate 103 and the bottom edge 2021 is shown. For example... Figure 8 As shown in (1), the movable fixing member 1 is moved so that the occlusal groove 1073 of the occlusal groove 107 faces the bottom edge 2021. The fixing member 1 can be moved along a third direction (and the bottom edge 2021 can also be moved if conditions permit), so that a small part of the bottom edge 2021 is inserted into the occlusal groove 107; as Figure 8 (2) As shown, the fixing member 1 is rotated clockwise so that the bottom edge 2021 gradually enters the occlusal groove 107. The fixing member 1 is moved further so that the bottom edge 2021 completely enters the occlusal groove 107.

[0111] The bottom edge 2021 is completely inserted into the occlusal groove 107, which can be understood as the bottom edge 2021 being unable to continue into the occlusal groove 107. For example, as shown... Figure 14 As shown, the first connecting plate 103 and the side edge 2023 of the component frame 202 abut against each other in a third direction; or, the bottom edge 2021 and the bottom of the engagement groove 107 abut against each other in a third direction.

[0112] In some other embodiments, the first connecting plate 103 and the side 2023 of the component frame 202 may not abut against each other in a third direction, for example, there may be a gap between the first connecting plate 103 and the side 2023.

[0113] During the process of the bottom edge 2021 entering the engagement groove 107, at least one of the first connecting plate 103 and the bottom edge 2021 deforms, causing the engagement groove 107 and the bottom edge 2021 to engage. Figure 9 This illustrates one state in which the occlusal groove 107 and the bottom edge 2021 are engaged. Figure 10 Another state of engagement between the occlusal groove 107 and the bottom edge 2021 is shown.

[0114] like Figure 9 As shown, the first connecting plate 103 deforms to achieve engagement between the engagement groove 107 and the bottom edge 2021. It should be noted that the deformation of the first connecting plate 103 may include an increase in the included angle β between the first connecting plate 103 and the first clamping plate 101; or, please refer to... Figure 6 and Figure 9 The deformation of the first connecting plate 103 may include deformation of the first portion 1031 and the second portion 1032 located on both sides of the engagement groove 107 in the first connecting plate 103; or, please refer to Figure 6 and Figure 9 The deformation of the first connecting plate 103 may include: deformation of the first part 1031 and the second part 1032 located on both sides of the interlocking groove 107 in the first connecting plate 103, and an increase in the included angle β between the first connecting plate 103 and the first clamping plate 101.

[0115] like Figure 10 As shown, the bottom edge 2021 deforms to achieve the engagement of the engagement groove 107 and the bottom edge 2021.

[0116] In some embodiments, the first connecting plate 103 and the bottom edge 2021 can be deformed to achieve engagement between the engagement groove 107 and the bottom edge 2021.

[0117] In this embodiment, the engagement groove 107 and the bottom edge 2021 engage, which can achieve a fixed connection between the fastener 1 and the photovoltaic module 2, so that the fastener 1 and the photovoltaic module 2 cannot move along the second direction, that is, the fastener 1 and the photovoltaic module 2 cannot move along the length direction of the module frame 202.

[0118] It should be noted that, Figure 8 The method of fixing the first connecting plate 103 and the bottom edge 2021 shown is only exemplary and not the only one. In the actual installation process, the moving direction of the fixing member 1 can be adjusted.

[0119] In the above embodiments, by moving the fixing member 1, the engagement groove 107 and the bottom edge 2021 can be engaged, thereby achieving a fixed connection between the fixing member 1 and the photovoltaic module 2. This simplifies the connection between the fixing member 1 and the photovoltaic module 2 and helps improve the installation efficiency of the photovoltaic module 2.

[0120] In this embodiment of the application, in order to ensure that the engagement groove 107 and the bottom edge 2021 engage, some dimensions of the fastener 1 need to meet the following requirements:

[0121] like Figure 2As shown, the thickness of the bottom edge 2021 along the first direction is t. Figure 7b As shown, the width of the bite groove 107 along the inclined direction of the first connecting plate 103 is b. The bite groove 107 includes a first bite groove wall 1071 and a second bite groove wall 1072. The second bite groove wall 1072 is farther away from the first clamping plate 101 than the first bite groove wall 1071. The distance in the first direction between the end of the first bite groove wall 1071 away from the first clamping plate 101 along the first direction and the end of the second bite groove wall 1072 close to the first clamping plate 101 along the first direction is c, where b≥t≥c. Where c=[b-(t1 / tanθ)]sinθ, θ is the angle between the first connecting plate 103 and the second direction, and t1 is the thickness of the first connecting plate 103.

[0122] As mentioned above, the first connecting plate 103 can abut against the side 2023 of the component frame 202 along a third direction. To facilitate the abutment of the first connecting plate 103 and the side 2023 along a third direction, as follows: Figure 6 As shown, the first connecting plate 103 includes a first part 1031 and a second part 1032. The first part 1031 connects one end of the second part 1032 along a third direction to the first clamping plate 101. Engaging grooves 107 are distributed between the first part 1031 and the second part 1032. The length of the second part 1032 along a third direction is less than the length of the first part 1031 along a third direction. Figure 14 As shown, the other end of the second part 1032 along the third direction is used to abut against the side 2023 of the component frame 202 along the third direction.

[0123] It is understood that the first part 1031 and the second part 1032 are distributed along the inclined direction of the first connecting plate 103, which is... Figure 7b The tilt direction is shown. The first part 1031 forms the first occlusal groove wall 1071 mentioned above, and the second part 1032 forms the second occlusal groove wall 1072 mentioned above. The end of the second part 1032 away from the first part 1031 forms the second end 1034 mentioned above, and the end of the first part 1031 away from the second part 1032 forms the first end 1033 mentioned above.

[0124] In the above embodiments, the second part 1032 has a shorter length along the third direction, which makes it easier to ensure that the other end of the second part 1032 along the third direction is used to abut against the side edge 2023 of the component frame 202 along the third direction; the first part 1031 has a longer length along the third direction, which can increase the contact area between the first connecting plate 103 and the bottom edge 2021, thereby increasing the friction and improving the interlocking effect.

[0125] In this embodiment, the deformability of the clamping groove 106 means that the width of the clamping groove 106 along the first direction can be reduced. For example, the width of the clamping groove 106 at the opening 1062 along the first direction can be reduced. Since the clamping groove 106 is formed by the connected first clamping plate 101 and second clamping plate 102, at least one of the first clamping plate 101 and the second clamping plate 102 can be deformed to enable the clamping groove 106 to deform. Since the first clamping plate 101 needs to contact the bottom edge 2021 or the pressure block 5 (described later), the second clamping plate 102 can be deformed to facilitate installation and deformation, thereby enabling the clamping groove 106 to deform.

[0126] To facilitate the deformation of the second clamping plate 102, such as Figure 7a As shown, the second clamping plate 102 includes a clamping plate body 1021 and a clamping plate connecting portion 1022. The clamping plate connecting portion 1022 and the clamping plate body 1021 are distributed along a second direction. The clamping plate body 1021 is connected to the first clamping plate 101. The clamping plate connecting portion 1022 has a first clamping plate end 10221 and a second clamping plate end 10222. The first clamping plate end 10221 is connected to the clamping plate body 1021, and the second clamping plate end 10222 is farther away from the first clamping plate 101 along a first direction than the first clamping plate end 10221. The clamping plate connecting portion 1022 is used for fixed connection with the bottom edge 2021.

[0127] It should be noted that the first clamping plate end 10221 is connected to the end of the clamping plate body 1021 that is away from the bottom of the groove 1061 along the second direction.

[0128] contrast Figure 13 and Figure 15 It can be seen that when the second clamping plate 102 and the bottom edge 2021 are fixedly connected, both the clamping plate body 1021 and the clamping plate connecting part 1022 are deformed, and both the clamping plate body 1021 and the clamping plate connecting part 1022 are offset towards the first clamping plate 101.

[0129] In the above structure, the deformation of the second clamping plate 102 can be increased, thereby increasing the deformation of the clamping groove 106, which is beneficial to improving the clamping force of the clamping groove 106 on the component mounting member 301, thus improving safety and reliability; moreover, the clamping plate connecting part 1022 can provide a guiding function for the component mounting member 301, making it easier for the component mounting member 301 to enter the clamping groove 106, thereby facilitating installation and improving installation efficiency.

[0130] In practice, the second clamping plate 102 can also be a flat plate parallel to the second direction, and is not limited to the above embodiment.

[0131] The bottom wall of the aforementioned clamping groove 106 can be either curved or flat, depending on the shape of the component mounting member 301. In some embodiments, the component mounting member 301 is a cable 301a with a circular cross-section, and the bottom wall of the clamping groove 106 is curved. In this case, as... Figure 6 As shown, the second clamping plate 102 and the first clamping plate 101 are indirectly connected by an arc-shaped plate 109 to form a clamping groove 106, and the arc-shaped plate 109 forms the bottom wall of the clamping groove 106.

[0132] In this embodiment, the specific structure for the fixed connection between the first clamping plate 101 and the bottom edge 2021, and the specific structure for the fixed connection between the second clamping plate 102 and the bottom edge 2021, are selected according to the actual situation.

[0133] In some embodiments, the first clamping plate 101 may be welded to the bottom edge 2021, or the first clamping plate 101 may be snapped onto the bottom edge 2021; correspondingly, the second clamping plate 102 may be fixed with a connecting member, which may be welded to the bottom edge 2021, or the connecting member may be snapped onto the bottom edge 2021.

[0134] In other embodiments, for ease of installation and maintenance, both the first clamping plate 101 and the second clamping plate 102 are used for fixed connection with the bottom edge 2021 by fasteners, which can be threaded fasteners or other fasteners. Figure 13 and Figure 14 As shown, in order to improve installation efficiency, the first clamping plate 101 and the second clamping plate 102 are used to fix them together by the same fastener 4 and bottom edge 2021.

[0135] In the above structure, the photovoltaic module 2 and the photovoltaic bracket 3 can be fixedly connected by a single fastener 4. Compared with the multiple fasteners required in related technologies, this effectively reduces the number of fasteners, improves installation efficiency, and also reduces the risk of safety accidents caused by high-altitude installation.

[0136] In the above structure, such as Figure 12 As shown, the first clamping plate 101 is provided with a first mounting hole 110, and the second clamping plate 102 is provided with a second mounting hole 111. Both the first mounting hole 110 and the second mounting hole 111 mate with the fastener 4. The bottom edge 2021 is provided with a through hole 20211, which also mates with the fastener 4. After the engagement groove 107 and the bottom edge 2021 engage, the first mounting hole 110 and the second mounting hole 111 are distributed relative to the through hole 20211 of the bottom edge 2021 along a first direction to ensure the installation of the fastener 4.

[0137] Continue to refer to Figure 12 As mentioned above, the second clamping plate 102 includes a clamping plate body 1021 and a clamping plate connecting part 1022, and the clamping plate connecting part 1022 is provided with the second mounting hole 111 mentioned above.

[0138] When the second clamping plate 102 is deformable, in order to facilitate the installation of fasteners 4, such as Figure 5As shown, the second mounting hole 111 is a strip-shaped hole, and the length direction of the strip-shaped hole is the inclined direction of the clamping plate connecting part 1022.

[0139] Please refer to Figure 12 The fastener 4 is configured to pass through the second clamping plate 102, the first clamping plate 101, and the bottom edge 2021 along a first direction. The fastener 4 passes through the clamping groove 106 along the first direction, and the fastener 4 and the fixing member 1 are fixedly connected. In order to facilitate the deformation of the second clamping plate 102, the fastener 4 passes through the second clamping plate 102 towards the bottom edge 2021.

[0140] like Figure 15 As shown, after the fastener 4 is fixed, the fastener 4 is closer to the slot 1062 of the clamping groove 106 than the component mounting part 301. In this way, the fastener 4 can prevent the component mounting part 301 from falling out of the clamping groove 106, which further improves safety and reliability.

[0141] For ease of disassembly, the fastener 4 is a threaded fastener, such as a screw or bolt. In this case, a threaded hole that mates with the thread of the fastener 4 is required, such as a single nut. To reduce the chance of a single nut falling off and improve installation efficiency, the second clamping plate 102 is provided with a threaded hole. In this case, the entire second clamping plate 102 or a portion of the second clamping plate 102 needs to be thickened.

[0142] like Figure 16 As shown, to facilitate the formation of a threaded hole, the fastener 1 also includes a nut 105, which forms a threaded hole and is fixed to the second clamping plate 102. The nut 105 is located on the side of the second clamping plate 102 away from the first clamping plate 101 along a first direction. In this case, the fastener 4 needs to pass through from the bottom edge 2021 into the second clamping plate 102.

[0143] In this embodiment of the application, the bottom edge 2021 of the component frame 202 is relatively thin, for example, the thickness of the bottom edge 2021 is 1.2mm. The load-bearing capacity of the bottom edge 2021 is weak, and the probability of failure of the bottom edge 2021 is relatively high under large load conditions. Figure 5 As shown, to reduce the probability of failure of the bottom edge 2021, the fastener 1 also includes a second connecting plate 104. The second connecting plate 104 is connected to one end of the first clamping plate 101 along a third direction, and the second connecting plate 104 and the first connecting plate 103 are located on one side of the first clamping plate 101 along a first direction; the second connecting plate 104 and the first clamping plate 101 form a receiving groove 108, which is used to receive the bottom edge 2021, and the receiving groove opening 1081 of the receiving groove 108 faces the first clamping plate 101 on the third direction side; the second connecting plate 104 is used for fixed connection with the bottom edge 2021. The receiving groove 108 is a through groove.

[0144] It should be noted that when the fastener includes the engagement groove 1073, the receiving groove 1081 and the engagement groove 1073 of the receiving groove 108 face the same side. To ensure that the engagement groove 107 and the bottom edge 2021 engage, the following requirements must also be met:

[0145] like Figure 7b As shown, the width of the receiving groove 108 along the first direction is h1, and the distance between the end of the second biting groove wall 1072 of the biting groove 107 away from the first clamping plate 101 along the first direction and the first clamping plate 101 in the first direction is h2, h2≥h1≥t, where t is the thickness of the bottom edge 2021 along the first direction.

[0146] In the above embodiments, the receiving groove 108 of the fixing member 1 accommodates the bottom edge 2021, which increases the contact area between the fixing member 1 and the bottom edge 2021, reduces the probability of the bottom edge 2021 failing, and also improves the connection stability and reliability between the fixing member 1 and the photovoltaic module 2.

[0147] In practice, the probability of bottom edge 2021 failure can be reduced through other methods. In some embodiments, such as... Figure 17 As shown, the fastener 1 also includes a pressure block 5, which can also be called a C-shaped pressure block. Figure 19 As shown, the pressure block 5 includes a top plate 501, a vertical plate 502, and a bottom plate 503. The top plate 501, vertical plate 502, and bottom plate 503 are distributed along a first direction. The vertical plate 502 connects the top plate 501 and the bottom plate 503. The top plate 501 and bottom plate 503 are located on one side of the vertical plate 502 along a second direction. The top plate 501, vertical plate 502, and bottom plate 503 form a receiving groove 505 for accommodating the component frame 202.

[0148] like Figure 18 As shown, the component frame 202 is located in the receiving groove of the pressure block 5. Figure 18 (Not shown in the image) Inside, the top plate 501 is pressed onto the component frame 202.

[0149] After the engagement groove 107 and the bottom edge 2021 are engaged, install the pressure block 5. For example... Figure 18 As shown, the bottom plate 503 of the pressure block 5 is located between the bottom edge 2021 and the first clamping plate 101. It can be understood that the bottom plate 503 and the bottom edge 2021 are distributed along the first direction, and the bottom plate 503 is closer to the second clamping plate 102 than the bottom edge 2021.

[0150] In the above embodiments, the first clamping plate 101 also needs to be fixedly connected to the base plate 503, and the second clamping plate 102 also needs to be fixedly connected to the base plate 503.

[0151] As mentioned above, the first clamping plate 101 and the second clamping plate 102 are fixedly connected to the bottom edge 2021 by the same fastener 4. In this case, the first clamping plate 101 and the second clamping plate 102 are fixedly connected to the bottom edge 2021 and the base plate 503 by the same fastener 4.

[0152] In the above embodiment, the bottom plate 503 of the pressure block 5 can share part of the force borne by the bottom edge 2021, reduce the force on the bottom edge 2021, realize the protection of the bottom edge 2021, reduce the probability of the bottom edge 2021 being damaged, and thus reduce the probability of the bottom edge 2021 failing.

[0153] In this application embodiment, the two embodiments described above for reducing the probability of bottom edge 2021 failure can be combined. In some embodiments, the fixing member 1 includes the aforementioned receiving groove 108, and the fixing member 1 also includes the aforementioned pressing block 5. The bottom plate 503 of the pressing block 5 is located between the bottom edge 2021 and the first clamping plate 101, and the receiving groove 108 is also used to receive the bottom plate 503 of the pressing block 5. In this way, the probability of bottom edge 2021 being damaged can be further reduced, thereby further reducing the probability of bottom edge 2021 failure.

[0154] In the above embodiments, in order to ensure that the engagement groove 107 and the bottom edge 2021 engage, the following requirement also needs to be met: h2≥h1≥t+t2. For example... Figure 19 As shown, t2 is the thickness of the base plate 503 along the first direction. For explanations of h2, h1, and t, please refer to the preceding text.

[0155] like Figure 12 As shown, in order to improve installation efficiency, the first clamping plate 101, the second clamping plate 102, and the second connecting plate 104 are used to fix them to the bottom edge 2021 by the same fastener 4.

[0156] It is understood that the second connecting plate 104 is provided with a third mounting hole 112, which is configured to be distributed relative to the through hole 20211 of the bottom edge 2021 along the first direction.

[0157] For disassembly, fastener 4 is a threaded fastener, such as a bolt or screw. In this case, a threaded hole is required to engage with the threaded fastener 4. To facilitate the creation of the threaded hole, as follows: Figure 6 As shown, the second connecting plate 104 is provided with a threaded hole 113 that mates with a fastener; or, the second clamping plate 102 is provided with a threaded hole 113 that mates with a fastener.

[0158] Continue to refer to Figure 6 In order to facilitate the formation of the threaded hole 113, the fastener also includes a nut 105, which forms the threaded hole 113 and is fixed to the second connecting plate 104 where the threaded hole 113 is located.

[0159] Please refer to Figure 16 To facilitate the formation of the threaded hole 113, the fastener also includes a nut 105, which forms a threaded hole. Figure 16 (Not shown in the image), nut 105 is fixed to the second clamping plate 102 where the threaded hole is located.

[0160] In the case where the fastener 1 includes a pressure block, in embodiments where the first clamping plate 101, the second clamping plate 102, and the second connecting plate 104 are fixedly connected to the bottom edge 2021 by the same fastener 4, or in embodiments where the first clamping plate 101 and the second clamping plate 102 are fixedly connected to the bottom edge 2021 by the same fastener 4, such as Figure 19 As shown, the base plate 503 of the pressure block 5 is provided with a fourth mounting hole 504, and the fastener 4 passes through the fourth mounting hole 504. The fourth mounting hole 504 can be a circular hole or a strip hole. For ease of installation, the fourth mounting hole 504 is a strip hole, and the length direction of the strip hole is the second direction.

[0161] In this embodiment of the application, in order to facilitate the production of the fastener 1 and improve installation efficiency, the first clamping plate 101, the second clamping plate 102, the first connecting plate 103, and the second connecting plate 104 can be an integral structure. Of course, the first clamping plate 101, the second clamping plate 102, the first connecting plate 103, and the second connecting plate 104 can also be a separate structure.

[0162] Accordingly, if the fastener 1 does not include the second connecting plate 104, the first clamping plate 101, the second clamping plate 102 and the first connecting plate 103 can be an integral structure or a separate structure.

[0163] The following describes the method of using a fastener 1 provided in an embodiment of this application.

[0164] like Figure 8 (1) As shown, the moving fastener 1 is moved so that the occlusal groove 1073 of the occlusal groove 107 faces the bottom edge 2021. The fastener 1 can be moved along a third direction (and the bottom edge 2021 can also be moved if conditions permit), so that a small part of the bottom edge 2021 is inserted into the occlusal groove 107.

[0165] like Figure 8 (2) As shown, rotate the fixing member 1 clockwise so that the bottom edge 2021 gradually enters the occlusal groove 107. Continue to move the fixing member 1 so that the bottom edge 2021 completely enters the occlusal groove 107. Figure 9 and Figure 10 This shows that the bottom edge 2021 is fully inserted into the engagement groove 107;

[0166] like Figure 11As shown, the installer lifts the photovoltaic module 2 with the fixing part 1 onto the module mounting part 301 of the photovoltaic bracket, with the slot 1062 of the clamping groove 106 facing the module mounting part 301, and moves the photovoltaic module 2 along the second direction so that the photovoltaic module 2 with the fixing part 1 is hung on the two module mounting parts 301. Figure 12 The diagram shows the photovoltaic module 2 hanging on two module mounting pieces 301; in this way, the photovoltaic module 2 can be stably hung on the module mounting pieces 301 without the need for installers to constantly support the photovoltaic module 2 to prevent it from slipping, and all installers at the workstation can move on to the next step.

[0167] like Figure 12 and Figure 13 As shown, the installer passes the fastener 4 through the second mounting hole 111 of the second clamping plate 102, the first mounting hole 110 of the first clamping plate 101, the through hole 20211 of the bottom edge 2021, the third mounting hole 112 of the second connecting plate 104, and the nut 105, and tightens the fastener 4; Figure 15 As shown, after the fastener 4 is tightened, the second clamping plate 102, the first clamping plate 101, the bottom edge 2021 and the second connecting plate 104 are locked in one go, and the component mounting piece 301 is clamped at the same time, thus completing the installation.

[0168] When the fastener 1 includes the pressure block 5, Figure 11 Before the steps shown, install pressure block 5. Figure 12 In the steps shown, the fastener 4 also needs to pass through the fourth mounting hole 504 of the pressure block 5.

[0169] The method of using the above-mentioned fastener 1 is merely exemplary and not the only one.

[0170] Since the fastener 1 provided in the above embodiments has the above-mentioned technical effects, and the photovoltaic power generation system includes the above-mentioned fastener 1, the photovoltaic power generation system also has the corresponding technical effects, which will not be elaborated here.

[0171] In a photovoltaic power generation system, the second and third directions are parallel to the plane where photovoltaic module 2 is located, and the first direction is perpendicular to the plane where photovoltaic module 2 is located. When photovoltaic module 2 is arranged at an angle relative to the horizontal direction, the first direction is relatively inclined to the vertical direction, the second direction is relatively inclined to the vertical direction, and the third direction can be perpendicular to the vertical direction. When photovoltaic module 2 is arranged parallel to the horizontal direction, the first direction is the vertical direction.

[0172] In photovoltaic power generation systems, such as Figure 3 and Figure 17As shown, the photovoltaic module 2 is fixedly connected to the same cable body 301a on both sides along the third direction by fasteners 1. This improves the stress balance of the photovoltaic module 2 and enhances its stability. Moreover, during installation, the photovoltaic module 2 is hung on the same cable body 301a on both sides along the third direction, which improves its stability before the fasteners 4 are installed, thus facilitating the installation of the fasteners 4 and improving the installation efficiency of the photovoltaic module 2.

[0173] For example, such as Figure 20 As shown, the fixing component 1 does not include the pressure block, and the fixing components 1 are symmetrically distributed on both sides of the photovoltaic module 2 along the third direction; as Figure 21 As shown, the fixing member 1 includes a pressure block 5, which is symmetrically distributed on both sides of the photovoltaic module 2 along the third direction.

[0174] Continue to refer to Figure 3 and Figure 17 At least two cable bodies 301a distributed along the second direction are fixedly connected to the same photovoltaic module 2 by fasteners 1. The second direction and the vertical direction are inclined. It should be noted that... Figure 15 This embodiment is also shown.

[0175] The above embodiments also improve the stress balance of the photovoltaic module 2 and enhance its stability. Moreover, during the installation process, hanging one photovoltaic module 2 on at least two cables 301a before installing the fasteners 4 improves the stability of the photovoltaic module 2, thereby facilitating the installation of the fasteners 4 and improving the installation efficiency of the photovoltaic module 2.

[0176] In practice, embodiments in which the photovoltaic module 2 is fixedly connected to the same cable body 301a on both sides along the third direction by fasteners 1, and embodiments in which at least two cables 301a distributed along the second direction are fixedly connected to the same photovoltaic module 2 by fasteners 1, can be combined or implemented individually.

[0177] The fastener 1 provided in this embodiment can also be used to fix other components and mounting parts with bottom edges. The clamping groove 106 of the fastener 1 is deformable and used to accommodate the mounting part. The first connecting plate 103 of the fastener 1 is used to fixally connect to the bottom edge of the component. The first clamping plate 101 and the second clamping plate 102 of the fastener 1 are both used to fixally connect to the bottom edge, and the clamping groove 106 is deformed to clamp the mounting part. Based on this, the fastener 1 can also be used in systems other than photovoltaic power generation systems.

[0178] The technical features mentioned above, as well as those shown individually in the accompanying drawings, can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are those explicitly described herein. Any one of the multiple technical features contained in the same statement can be applied independently, without necessarily being applied together with other technical features.

[0179] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
