[0050] The embodiments of this application will now be described in detail.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0052] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed in a specific orientation.

[0053] The operation is therefore not to be construed as a limitation of this application.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] Before explaining the photovoltaic system provided in the embodiments of this application, the application scenarios of the photovoltaic system provided in the embodiments of this application will be specifically described first:

[0056] With the development of photovoltaic technology, the application scenarios of photovoltaic systems have been further developed. For example, photovoltaic systems can be installed on the roofs of carports, awnings, sunrooms, and connecting corridors. A photovoltaic system typically includes photovoltaic modules and a support structure. The photovoltaic modules are used for photoelectric conversion, and the support structure is used to support the photovoltaic modules.

[0057] In actual installation, the process involves drilling holes at the corresponding installation positions on the photovoltaic module frame and the bracket, placing the frame on top of the bracket, and then fixing the bracket to the frame with bolts or by welding. This installation operation is quite complicated. Furthermore, because the photovoltaic system is installed at a high position, installers need to erect scaffolding to install the frame and bracket, which is not only inconvenient for on-site construction but also consumes a lot of manpower and resources.

[0058] Therefore, this application provides a photovoltaic system. The photovoltaic system provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0059] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, a photovoltaic system according to some embodiments of this application includes: a bracket 1, a photovoltaic module, and a clamping member 3. The bracket 1 has a first mounting portion 11, and the first mounting portion 11 has a positioning protrusion 111. The photovoltaic module includes a frame 2, and the frame 2 has a second mounting portion 21. The frame 2 is disposed on the bracket 1. The second mounting portion 21 and the first mounting portion 11 are disposed along a first direction X. The second mounting portion 21 has a positioning hole 211, and the positioning protrusion 111 is inserted into the positioning hole 211. The clamping member 3 clamps the second mounting portion 21 and the first mounting portion 11 on both sides along the first direction X to fix the bracket 1 and the frame 2.

[0060] In this embodiment, by providing a positioning protrusion 111 on the first mounting portion 11 of the bracket 1, when installing the frame 2 of the photovoltaic module onto the bracket 1, the installer only needs to insert the positioning hole 211 in the frame 2 into the positioning protrusion 111 on the bracket 1 to achieve limiting and fixing of the frame 2 and the bracket 1 in a plane perpendicular to the first direction X. Furthermore, by clamping the first mounting portion 11 and the second mounting portion 21 on both sides along the first direction X using the clamping member 3, limiting and fixing of the frame 2 and the bracket 1 in the first direction X can be achieved. Compared to traditional bolt connections or welding methods, the limiting structure of this application is more convenient and simpler to install. The installer can achieve the connection and fixing of the frame 2 and the bracket 1 simply by inserting and clamping, reducing the input of manpower and materials and improving the convenience of on-site construction.

[0061] It should be noted that the first direction X specifically refers to the connection direction between the frame 2 and the bracket 1, that is, the height direction of the bracket 1. In actual operation, the first direction X is specifically the vertical direction. Of course, this application also proposes a second direction Y and a third direction Z. The second direction Y and the third direction Z intersect with the first direction X. Preferably, the three are perpendicular to each other. The second direction Y specifically refers to the length direction of the photovoltaic module, and the third direction Z specifically refers to the width direction of the photovoltaic module. These will not be elaborated further.

[0062] In practical applications, bracket 1 can be installed on the ground, roof, carport roof, sunroom roof, corridor roof, etc., as needed. Bracket 1 mainly serves a supporting function, and multiple photovoltaic modules can be installed in an array on bracket 1. Figure 3 As shown in the figure, part A circled in the figure is the installation position of the photovoltaic module. The bracket 1 can be equipped with support columns according to the installation environment, and the tilt angle of the bracket 1 can be adjusted as needed to allow the photovoltaic module to better absorb sunlight.

[0063] Specifically, a photovoltaic module may include a cell laminate 8 and a frame 2. The frame 2 covers the perimeter of the cell laminate 8 to protect the perimeter of the cell laminate 8. Photovoltaic modules are typically formed by laminating the cell laminate 8 first, and then using sealant to bond and fix the frame 2 to the outer perimeter of the cell laminate 8. The cell laminate 8 is used for photovoltaic power generation.

[0064] Understandably, such as Figure 2 and Figure 6 As shown, the first mounting part 11 is specifically disposed on the side of the bracket 1 facing the frame 2, and a positioning protrusion 111 is provided in the first mounting part 11; the second mounting part 21 is specifically disposed on the side of the frame 2 facing the bracket 1, and a positioning hole 211 is provided in the second mounting part 21. The number of positioning protrusions 111 and positioning holes 211 can be multiple, with multiple positioning protrusions 111 extending along the bracket...

[0065] The frame 1 is spaced along its length, and the position of the positioning hole 211 corresponds to the position of the positioning protrusion 111 so that the two can be inserted together.

[0066] In practical applications, the frame 2 is generally a standard part, and its specifications vary, which results in different positions of the positioning holes 211 on different frame 2s, such as... Figure 10 As shown, in order to enable the bracket 1 to match various sizes of frame 2, the positioning protrusion 111 can be made adjustable. For example, the positioning protrusion 111 can be formed at the required position by on-site stamping or bolt installation. Alternatively, during the processing of the bracket 1, multiple bendable movable pieces can be provided on the first mounting part 11, and the movable pieces at the required position can be bent on-site to form the positioning protrusion 111. Of course, other structures that allow the position of the positioning protrusion 111 to be adjustable can also be used. Those skilled in the art can set it according to actual needs, and this application does not limit this.

[0067] Understandably, the positioning protrusion 111 can be any shape, such as a cylinder, a square column, or a sheet, as long as it can be inserted into the positioning hole 211. Those skilled in the art can set it according to actual needs, and this application does not limit it in this regard.

[0068] It should be explained that the clamping member 3 fixes the frame 2 to the bracket 1 by clamping the first mounting part 11 and the second mounting part 21. Specifically, the clamping member 3 is a type of snap-fit, such as... Figure 17 and Figure 18As shown, the clamping member 3 has a clamping space 31. One side wall of the clamping space 31 along the first direction X abuts against the first mounting part 11, and the other side wall of the clamping space 31 along the first direction X abuts against the second mounting part 21, thereby fixing the first mounting part 11 and the second mounting part 21 along the first direction X, which facilitates installation and ensures the stability of the connection.

[0069] Of course, in some embodiments, the clamping member 3 is also provided with a lever 32, such as Figure 17 and Figure 18 As shown, one end of the paddle 32 is fixedly connected to the body of the clamping member 3, and the other end can move within the clamping space 31 to deform, thereby applying force to the clamped part within the clamping space 31 and improving the clamping effect of the clamping member 3.

[0070] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the bracket 1 includes a bracket body 12 and a first support member 13. The bracket body 12 is disposed on one side of the frame 2 along the first direction X. The first support member 13 is connected to the side of the bracket body 12 facing the frame 2 to form a first mounting portion 11. A first water guide groove 121 is formed in the bracket body 12. The first water guide groove 121 has...

[0071] There is a first opening 1211, which faces the border 2.

[0072] In this embodiment of the application, the first water guide channel 121 in the bracket body 12 has a first opening 1211 facing the frame 2, so as to collect rainwater and the like between the two frames 2, and then draw water from the photovoltaic system through the first water guide channel 121, thereby avoiding the impact of rainwater and the like on the photovoltaic module and improving the reliability and safety of the photovoltaic system.

[0073] In specific applications, such as Figure 5 and Figure 6 As shown, the first water guide channel 121 extends along the second direction Y, as... Figure 1 and Figure 2 As shown, the two frames 2 of the two photovoltaic modules are respectively set on both sides of the first opening 1211, so that rainwater and other water in the two photovoltaic modules can flow out from the first water channel 121 along the second direction Y.

[0074] It should be noted that, as Figure 3 and Figure 4As shown, the bracket body 12 specifically refers to the horizontal bottom profile and the vertical profile. The vertical profile and the bottom profile together form a first water guide groove 121, which extends along the second direction. The first support member 13 is connected to the side of the bracket body 12 facing the frame 2 to form a first mounting part 11, thereby facilitating the mounting of the frame 2 on the bracket 1. Specifically, the first support member 13 can be any form of connector such as a connecting plate or a connecting block, as long as it can be connected to the bracket body 12 to form the first mounting part 11. Of course, the first support member 13 and the bracket body 12 can be integrally formed or separately formed. Those skilled in the art can set it according to actual needs, and this application does not limit it in this regard.

[0075] For example, the bracket body 12 and the first support member 13 are integrally formed parts, specifically made of aluminum alloy, which is convenient to process and has a lower cost.

[0076] like Figure 1 and Figure 2 As shown, there are two first support members 13. The two first support members 13 are respectively connected to the two sides of the first opening 1211 and connected to the bracket body 12 to form two first mounting parts 11, so that they can be connected to the two frame 2.

[0077] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the photovoltaic system further includes a water guide 4. The frame 2 has a water guide 4 on at least one side along the second direction Y. The first support member 13 has a bayonet 131, and at least a portion of the end of the water guide 4 is engaged within the bayonet 131. The second direction Y is parallel to the extending direction of the first water guide channel 121. The bracket body 12 also has a second water guide channel 122, which is spaced apart from the first water guide channel 121 along the third direction Z.

[0078] The water component 4 is provided with a third water guide channel 41, which is connected to the second water guide channel 122. The third direction Z is perpendicular to the first direction X and the second direction Y respectively.

[0079] In this embodiment, the third water guide channel 41 of the water guide 4 is connected to the second water guide channel 122 in the bracket body 12, so as to collect and export rainwater and other water flowing down the frame 2 along the third direction Z, thereby avoiding the impact of rainwater and other water on the photovoltaic module and improving the reliability and safety of the photovoltaic system.

[0080] In specific applications, such as Figure 3 , Figure 4 and Figure 5As shown, at least part of the end of the water guide 4 is engaged in the bayonet 131. The third water guide channel 41 of the water guide 4 extends along the third direction Z, and the second water guide channel 122 extends along the second direction Y. In actual use, the water guide 4 can collect rainwater and other water from the photovoltaic module along the third direction Z. Then, the rainwater and other water in the third water guide channel 41 of the water guide 4 flows into the second water guide channel 122, thereby draining the water and avoiding damage to the photovoltaic module.

[0081] It should be explained that a bayonet 131 is provided in the first support member 13, and the installation efficiency of the water guide member 4 is improved by at least partially engaging the end of the water guide member 4 in the bayonet 131.

[0082] Understandably, such as Figure 1 and Figure 3 As shown, in practical applications, frame 2 is set at the circumferential edge of the photovoltaic module, and multiple photovoltaic module arrays are set on bracket 1, as follows. Figure 1 As shown, the first opening 1211 of the first water guide channel 121 is located between the two photovoltaic modules, enabling it to collect and drain rainwater and other water from the two photovoltaic modules along the second direction Y; as Figure 3 As shown, the water guide 4 is set at the end of the frame 2, so that rainwater and other water in the photovoltaic module can be collected along the third direction Z, and then the rainwater and other water can be discharged through the second water guide channel 122. This can ensure that rainwater and other water in the photovoltaic system will not accumulate and damage the photovoltaic module, thus improving the reliability and safety of the photovoltaic system.

[0083] In a specific application, the second water guide channel 122 has a second opening 1221 facing the water guide component 4. The second water guide channel 122 is connected to the third water guide channel 41 through the second opening 1221, thereby realizing the flow and discharge of rainwater, etc.

[0084] Understandably, the water guide 4 can achieve a stable connection by engaging with the bayonet 131. At this time, the end of the water guide 4 and the bayonet 131 can be connected by an interference fit. Of course, the water guide 4 can also be supported in the first direction X by other support methods, and this application does not limit this.

[0085] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this application, along the first direction X, the guide

[0086] The surface of the water element 4 facing the frame 2 is flush with the surface of the first support element 13 facing the frame 2.

[0087] In this embodiment, by setting the surface of the water guide 4 facing the frame 2 to be flush with the surface of the first support 13 facing the frame 2, the influence of the water guide 4 on the installation of the frame 2 is avoided, and the flatness of the frame 2 during installation is improved.

[0088] In practical applications, the water guide 4 is placed between the bracket 1 and the frame 2, which can reduce the overall space occupied. The side surface of the water guide 4 facing the frame 2 is made flush with the side surface of the first support 13 facing the frame 2. This way, when the frame 2 is installed, the bottom surface of the frame 2 can be installed on a horizontal plane, which improves the stability and flatness of the installation.

[0089] It should be explained that the surface of the water guide 4 facing the frame 2 is flush with the surface of the first support 13 facing the frame 2, specifically, the surface of the water guide 4 facing the frame 2 and the surface of the first support 13 facing the frame 2 are in the same plane.

[0090] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the bracket 1 further includes a second support member 14, which is connected to the side of the bracket body 12 facing the frame 2, and the side of the water guide member 4 away from the frame 2 abuts against the second support member 14.

[0091] In this embodiment, by providing a second support member 14 in the bracket 1, the second support member 14 can abut against the side of the water guide member 4 away from the frame 2, thereby supporting the water guide member 4 and improving the connection stability of the water guide member 4.

[0092] In specific applications, the second support member 14 can be any form of connector such as a connecting plate or a connecting block, as long as it can abut against the bottom of the water guide member 4 to form support; of course, the second support member 14 and the bracket body 12 can be integrally formed or separately formed. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0093] For example, the bracket body 12 and the second support member 14 are integrally formed parts, specifically made of aluminum alloy, which is convenient to process and has a lower cost.

[0094] Understandably, the second support member 14 can be set on one side of the second opening 1221 of the second water guide channel 122, or it can be set on the bottom profile. It is sufficient that it supports the water guide member 4 without obstructing the second opening 1221. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0095] like Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of this application, the photovoltaic system further includes a limiting member 5, which is detachably connected to the side of the first mounting portion 11 facing the frame 2 to form a positioning protrusion 111.

[0096] In this embodiment, the limiting member 5 can be detachably connected to the side of the first mounting part 11 facing the frame 2, thereby forming a positioning protrusion 111. The position of the positioning protrusion 111 can be determined according to the connection position of the limiting member 5, thereby making the position of the positioning protrusion 111 adjustable and adaptable to different specifications of the frame 2, thus improving the adaptability of the bracket 1.

[0097] In practical applications, since the frame 2 is usually a standard part, the position of the positioning hole 211 of the frame 2 varies depending on the specifications, such as... Figure 6 and Figure 7 As shown, the two frame 2s have different lengths and are detachably connected by the limiting piece 5 to form a positioning protrusion 111. The position of the positioning protrusion 111 can be flexibly adjusted according to the specific size of the frame 2, which improves the installation efficiency.

[0098] It should be explained that the limiting component 5 can be a self-tapping screw, bolt, pin, etc. In actual use, the self-tapping screw can be installed at the corresponding position of the positioning hole 211 of the frame 2 as needed on site, or a bolt or pin can be drilled to form a positioning protrusion 111. The positioning protrusion 111 is then inserted into the positioning hole 211 to connect the frame 2 and the bracket 1. Those skilled in the art can make the settings according to actual needs, and this application does not limit this.

[0099] In some embodiments of this application, the positioning protrusion 111 and the bracket 1 are integrally formed. Specifically, the positioning protrusion 111 is formed on the side of the bracket 1 facing the frame 2 by means of welding, stamping, setting a bendable part, etc. For example, the positioning protrusion 111 is formed by stamping on the first mounting part 11; of course, it can also be any other integrally formed structure that can flexibly adjust the position of the positioning protrusion 111.

[0100] like Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of this application, the first mounting part 11 is provided with a plurality of mounting holes 110, the plurality of mounting holes 110 are spaced apart along the second direction Y, and the limiting member 5 is detachably connected to a portion of the mounting holes 110 to form a positioning protrusion 111, the second direction Y being perpendicular to the first direction X.

[0101] In this embodiment of the application, by providing a plurality of mounting holes 110 on the first mounting portion 11, the...

[0102] The limiting member 5 is detachably connected to a portion of the mounting holes 110 to form a positioning protrusion 111. Thus, when installing the bracket 1 and the frame 2, the positioning protrusion 111 can be directly inserted into the positioning hole 211, thereby improving installation efficiency. At the same time, since there are multiple mounting holes 110, the installer can adjust the position of the limiting member 5 according to the actual position of the positioning hole 211 of the frame 2 to connect the limiting member 5 into the mounting hole 110 corresponding to the positioning hole 211, thereby improving the adaptability of the bracket 1 and enhancing the overall installation efficiency.

[0103] In specific applications, the mounting holes 110 are spaced along the second direction Y. Specifically, they can be set at a certain interval or spaced according to the position of the positioning holes 211 on the frame 2 of different specifications, so that the position of the mounting holes 110 can match the positioning holes 211 on the frame 2 of various specifications.

[0104] It should be explained that the mounting hole 110 can be any shape of mounting hole, such as round hole, elliptical hole, square hole, polygonal hole, etc. The limiting member 5 can be detachably connected to form the positioning protrusion 111. Of course, the mounting hole 110 can be in the form of through hole, blind hole, etc., as long as the limiting member 5 can be connected in the mounting hole 110. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0105] Understandably, the limiting member 5 is detachably connected to the mounting hole 110 to form a positioning protrusion 111. Specifically, a portion of the limiting member 5 is connected to the mounting hole 110, while another portion is exposed outside the first mounting portion 11, thereby forming the positioning protrusion 111 on the exposed portion. For example, as shown in the figure... Figure 9 As shown, the limiting member 5 is a bolt, which passes through the mounting hole 110 and is fixed to the bracket 1 by a nut. The end of the bolt is exposed in the first mounting part 11, thereby forming a positioning protrusion 111.

[0106] like Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of this application, the first mounting portion 11 is provided with a strip hole 113 extending along the second direction Y, and the limiting member 5 is adjustablely connected to the strip hole 113 to form a positioning protrusion 111, wherein the second direction Y is perpendicular to the first direction X.

[0107] In this embodiment, by providing a strip-shaped hole 113 extending along the second direction Y on the first mounting part 11, the limiting member 5 is adjustablely connected to the strip-shaped hole 113 to form a positioning protrusion 111. Therefore, when installing the bracket 1 and the frame 2, the positioning protrusion 111 can be directly inserted into the positioning hole 211, thereby improving installation efficiency. Simultaneously, the installer can adjust the installation according to the actual installation location.

[0108] The position of the positioning hole 211 of frame 2 is adjusted to adjust the position of the limiting member 5 within the strip hole 113, thereby improving the adaptability of bracket 1 and enhancing the overall installation efficiency.

[0109] In specific applications, the position of the strip hole 113 corresponds to the position of the positioning hole 211 of the frame 2 of different specifications, and can match the position of the positioning hole 211 of the frame 2 of multiple specifications at the same time. Thus, the installer can adjust the specific position of the limiting member 5 in the strip hole 113 according to the requirements. For example, the limiting member 5 is specifically a bolt and a nut. Loosen the nut, adjust the bolt to the position in the strip hole 113 corresponding to the positioning hole 211, and tighten the nut, so that the exposed part of the bolt forms a positioning protrusion 111.

[0110] It should be explained that the specific length of the strip hole 113 can be set according to the position of the positioning hole 211 of the frame 2 of different specifications, so as to cover the positioning hole 211 of both the frame 2 of the smallest and the frame 2 of the largest specifications. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0111] like Figure 15 and Figure 16 As shown, in some embodiments of this application, the first mounting portion 11 is provided with a receiving groove 112, and a bendable portion 1121 is provided in the receiving groove 112. The bendable portion 1121 is connected to the bracket 1. The bendable portion 1121 can be bent and deformed relative to the bracket 1 to switch between a flattened state and a bent state. In the flattened state, the bendable portion 1121 extends toward the receiving groove 112 to be received in the receiving groove 112. In the bent state, the bendable portion 1121 bends and extends toward the frame 2, and at least partially extends into the positioning hole 211 to form a positioning protrusion 111. There are multiple bendable portions 1121, and the multiple bendable portions 1121 are arranged at intervals along the second direction Y. The first mounting portion 11 is provided with a receiving groove 112 at a position corresponding to the bendable portion 1121. The second direction Y is perpendicular to the first direction X.

[0112] In this embodiment, the bendable portion 1121 can be bent and deformed relative to the bracket 1 to switch between a flattened state and a bent state. Thus, when the bendable portion 1121 is in the flattened state, it extends towards the receiving groove 112 and can be accommodated within the receiving groove 112, facilitating the transport of the bracket 1 and preventing deformation of the bendable portion 1121 due to collision during transport. When the bendable portion 1121 is in the bent state, it can bend and extend towards the frame 2, and at least partially extend into the positioning hole 211 to form a positioning protrusion 111, thereby at least partially inserting the bendable portion 1121 into the positioning hole 211 to achieve connection and positioning between the frame 2 and the bracket 1. By providing the bendable portion 1121...

[0113] The bracket 1 can be adapted to different specifications of frame 2, thereby improving the adaptability of the bracket 1 and thus improving the installation efficiency of the photovoltaic system. Compared with related technologies, this application does not require corresponding holes to be made on the bracket 1 to adapt to different specifications of frame 2, or to make holes on the frame 2 on the construction site, which reduces the mold opening cost and improves the installation efficiency.

[0114] In specific applications, the bendable part 1121 and the bracket 1 are integrally formed. For example, in actual processing, such as... Figure 15 The circled part B and Figure 16 As shown in section C, a U-shaped groove is formed on the first support member 13. The part inside the U-shaped groove can be bent to form a positioning protrusion 111. During on-site installation, as... Figure 16 As shown in section C, the installer can bend the bendable part 1121 at the corresponding position to form a positioning protrusion 111 according to the position of the positioning hole 211, and then insert it into the positioning hole 211 to form a connection and positioning.

[0115] It should be explained that the size of the bendable part 1121 should be greater than or equal to the thickness of the second mounting part 21, so that it can be inserted into the positioning hole 211 after bending.

[0116] Understandably, in actual operation, when processing bracket 1, the receiving groove 112 and the bendable part 1121 are processed together, and then the bendable part 1121 is placed in a flattened state, such as... Figure 15 As shown in section B, this facilitates transportation. After transporting bracket 1 to the site, the installer bends the corresponding bendable part 1121 towards the frame 2 according to the position of the positioning hole 211, forming the positioning protrusion 111, and then inserts it into the positioning hole 211. Figure 16 The circled section C is used to connect and position the bracket 1 to the frame 2.

[0117] In specific applications, the specific number of bendable portions 1121 is determined according to the length of the first mounting portion 11, and the spacing between two adjacent bendable portions 1121 can be determined according to the position of the positioning holes 211 of various specifications of the frame 2. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0118] It should be explained that the number of receiving grooves 112 corresponds to the number of bendable parts 1121. In actual processing, opening one receiving groove 112 will correspondingly form one bendable part 1121.

[0119] like Figure 9 As shown, in some embodiments of this application, the bracket 1 has a waterproof layer 7 on the side facing the frame 2. Specifically, both the first support member 13 and the second support member 14 have a waterproof layer 7 on the side facing the frame 2, thereby isolating the first support member 13 from the frame 2 and isolating the second support member 14 from the frame 2.

[0120] Component 14 is isolated from water guide component 4 to prevent corrosion by rainwater and subsequent chemical reactions, thereby improving the reliability and service life of bracket 1.

[0121] In specific applications, the material of the waterproof layer 7 can be at least one of EPDM rubber, high-density polyethylene self-adhesive, polyvinyl chloride, polyethylene polypropylene composite material, thermoplastic polyolefin, ester polyurethane waterproof coating, etc. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0122] like Figure 7 , Figure 9 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments of this application, the photovoltaic system further includes a piercing mechanism 6; the piercing mechanism 6 is disposed on the positioning protrusion 111, and the piercing mechanism 6 is used to pierce the protective layer on the surface of the bracket 1 so that the bracket 1 and the frame 2 are electrically connected.

[0123] In this embodiment, by providing a piercing mechanism 6 on the positioning protrusion 111, the protective layer on the surface of the bracket 1 can be pierced, thereby making the bracket 1 electrically connected to the frame 2 through the positioning protrusion 111. Compared with related technologies, this avoids the need to use an additional grounding wire to ground the frame 2, reduces the amount of materials in the photovoltaic system, and improves the ease of installation and installation efficiency.

[0124] It should be explained that in related technologies, in order to avoid corrosion during long-term use, a protective layer is provided on the surface of the frame 2 and the bracket 1. The protective layer includes a waterproof layer, an insulating layer, etc. Usually, the protective layer is insulating, but the piercing mechanism 6 in this application can pierce the protective layer on the surface of the bracket 1, thereby enabling the bracket 1 and the frame 2 to be electrically connected together through the positioning protrusion 111, so as to ground the frame 2.

[0125] In specific applications, the piercing mechanism 6 can be disposed on the limiting member 5 or on the bendable portion 1121. Specifically, when the piercing mechanism 6 is disposed on the limiting member 5, the limiting member 5 is electrically connected to the bracket 1, and the piercing mechanism 6 is disposed on the surface of the limiting member 5 facing the frame 2, which can pierce the protective layer of the inner wall of the positioning hole 211 or other parts of the frame 2. When the piercing mechanism 6 is disposed on the bendable portion 1121, the piercing mechanism 6 is disposed at the end of the bendable portion 1121 away from the bracket 1, which facilitates piercing the protective layer of the inner wall of the positioning hole 211.

[0126] like Figure 7 , Figure 9 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments of this application, the piercing mechanism 6 is disposed in the clamping member 3. The piercing mechanism 6 is used to pierce the protective layer on the surface of the frame 2 and the bracket 1 so that the bracket 1 and the frame 2 are electrically connected.

[0127] In this embodiment, by setting the piercing mechanism 6 in the clamping member 3, the protective layer on the surface of the frame 2 and the bracket 1 can be pierced when the clamping member 3 is installed, thereby forming an electrical connection between the bracket 1 and the frame 2. Compared with related technologies, this avoids the need to use an additional grounding wire to ground the frame 2, reduces the amount of materials in the photovoltaic system, and improves the ease of installation and installation efficiency.

[0128] It should be explained that the piercing mechanism 6 is specifically provided at the part where the clamping member 3 abuts against the first mounting part 11, so that it can pierce the surface protective layer of the first mounting part 11 when clamping. At the same time, the piercing mechanism 6 is also provided at the part where the clamping member 3 abuts against the second mounting part 21, so that it can pierce the surface protective layer of the second mounting part 21 when clamping, thereby forming an electrical connection between the bracket 1 and the frame 2.

[0129] It should be explained that the clamping member 3 is specifically a metal part or has an internal structure that can conduct electricity, so that an electrical connection can be formed between the bracket 1 and the frame 2 bracket through the clamping member 3.

[0130] like Figure 7 , Figure 9 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments of this application, the photovoltaic system further includes a limiting member 5, which includes a limiting part 51 and a connecting part 52 connected to each other. The connecting part 52 is detachably connected to the first mounting part 11. The limiting part 51 is exposed outside the bracket 1 to form a positioning protrusion 111. The piercing mechanism 6 includes a first piercing part 61 and a second piercing part 62. The first piercing part 61 is disposed on the circumferential surface of the limiting part 51. The limiting part 51 is inserted into the positioning hole 211. The first piercing part 61 abuts against the hole wall of the positioning hole 211 and pierces the protective layer on the surface of the hole wall. The second piercing part 62 is disposed on the side of the limiting part 51 facing the bracket 1. The limiting part 51 abuts against the bracket 1 and pierces the protective layer on the surface of the bracket 1.

[0131] In this embodiment, the limiting part 51 is exposed on the bracket 1 to form a positioning protrusion 111, thereby enabling it to be inserted into the positioning hole 211. Simultaneously, the first piercing part 61, located on the circumferential surface of the limiting part 51, can abut against and pierce the protective layer on the surface of the positioning hole 211 when the limiting part 51 is inserted into it. The second piercing part 62 on the side of the limiting part 51 facing the bracket 1 can pierce the protective layer on the surface of the bracket 1 when it is installed on the bracket 1, thereby forming an electrical connection between the bracket 1 and the frame 2. While satisfying the installation connection requirements, the limiting member 5 forms an electrical connection between the bracket 1 and the frame 2 bracket. Compared with related technologies, this reduces material input and improves installation convenience.

[0132] This improved installation efficiency.

[0133] It should be noted that, as Figure 12 , Figure 13 and Figure 14 As shown, the first piercing part 61 can specifically be a spike disposed on the circumferential surface of the limiting part 51 and extending radially, so that it can pierce the surface protective layer of the positioning hole 211 wall while abutting against the positioning hole 211. Of course, it can also be other forms of piercing structure, as long as it can pierce the surface protective layer of the frame 2. The second piercing part 62 can specifically be a spike disposed on the side of the limiting part 51 facing the bracket 1 and extending axially, so that when the connecting part 52 is installed on the bracket 1, the second piercing part 62 can abut against the bracket 1 and pierce the protective layer on the surface of the bracket 1. Of course, it can also be other forms of piercing mechanism, as long as it can pierce the surface protective layer of the bracket 1. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0134] The following is a brief description of the installation process of the photovoltaic system of this application, using the bracket 1 formed by the positioning protrusion as the bendable part 1121:

[0135] The water guide 4 is installed on the bracket 1 along the first direction X, with at least a portion of its end abutting against the bayonet 131, and the side of the water guide 4 facing away from the frame 2 abutting against the second support 14. Then, the frame 2 is placed on the bracket 1 along the first direction X, and the bendable portion 1121 corresponding to the positioning hole 211 is bent. The bendable portion 1121 is then inserted into the positioning hole 211, and the clamping member 3 is clamped on both sides of the first mounting portion 11 and the second mounting portion 21. This process is repeated to complete the installation at other positions.

[0136] As can be seen from the above installation process, compared with the traditional bolt connection or welding method, the limiting structure of this application is more convenient and simple to install. The installer can connect and fix the frame 2 and the bracket 1 by simply plugging and clamping, which reduces the input of manpower and material resources and improves the convenience of on-site construction.
