[0010] In one embodiment, the snap-fit ​​portion includes a first sidewall, a second sidewall, and a third sidewall connecting the first sidewall and the second sidewall. The third sidewall is used to abut against the bottom wall of the first connecting groove. The first sidewall abuts against one of the groove walls of the first connecting groove. The second sidewall is inclined relative to the first sidewall and gradually moves closer to the first sidewall in a direction away from the third sidewall.

[0011] In one embodiment, at the connection of the third sidewall, the distance between the opposite sides of the first sidewall and the second sidewall is adapted to the groove width of the first connecting groove.

[0012] In one embodiment, the first connecting groove has a first rolled edge at the opening, the snap-fit ​​portion includes a fourth sidewall, the fourth sidewall is fitted against the first rolled edge, and the first connecting portion is connected to the fourth sidewall.

[0013] In one embodiment, the snap-fit ​​portion has a cavity.

[0061] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0062] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0063] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0064] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0065] When connecting and fixing existing support beams, the following methods are generally used: Figures 1 to 3 The connection method shown specifically requires the use of purlin supports (such as angle steel, L-plates, etc.) and bolts and other connectors to fix the two beams together. Taking the first beam and the second beam as an example, related technologies use angle steel as purlin supports and bolts and other connectors to fix the first beam and the second beam together. However, this connection method mostly requires drilling holes in the first beam and the second beam. Because on-site drilling is difficult and inefficient, and other adverse factors caused by on-site drilling must also be considered, there are problems with inconvenient connection and unstable installation.

[0066] Reference Figures 1 to 3 This application proposes a connecting component, a photovoltaic support structure, and a photovoltaic power station. Through the design of the connecting component, the beams can be connected without on-site drilling, effectively solving the problems of inconvenient connection and unstable installation of existing supports.

[0067] Reference Figures 4 to 22 In an embodiment of this application, a connecting component is applied to a bracket, which includes a first beam 110 and a second beam 120, the second beam 120 having a first connecting groove 1201.

[0068] Optionally, one of the first beam 110 and the second beam 120 is a main beam, and the other is a secondary beam. This application mainly uses the first beam 110 as the main beam and the second beam 120 as the secondary beam as an example for illustration. Embodiments using the first beam 110 as the secondary beam and the second beam 120 as the main beam can be referred to accordingly, and will not be repeated here. (Refer to...) Figures 4 to 22 The second beam 120 has a first connecting groove 1201 or other grooves. In the embodiments of this application, the second beam 120 can be, but is not limited to, C-shaped steel (with a C-shaped cross-section, used for lightweight structures, etc.), L-shaped steel (with an L-shaped cross-section, used for right-angle supports, etc.), and U-shaped steel (with a U-shaped cross-section, used for supports with high load-bearing requirements, such as channel steel, etc.); the specific configuration can be determined according to actual conditions and is not limited here. Specifically, a groove can be cut into the second beam 120 to construct the first connecting groove 1201; or the groove of the C-shaped steel or the groove of other steel can be used as the first connecting groove 1201.

[0069] The connecting assembly includes a first connector 200 and a second connector 300. The first connector 200 includes a first connecting portion 210 and a snap-fit ​​portion 220. The snap-fit ​​portion 220 is used to snap into a first connecting groove 1201. The first connecting portion 210 is connected to the snap-fit ​​portion 220 and extends out of the first connecting groove 1201. The first connector 200 is snapped into the first connecting groove 1201 by the snap-fit ​​portion 220, so that the first connector 200 can be securely connected to the second beam 120 and the first connector 200 is prevented from shifting or falling off relative to the second beam 120.

[0070] The second connector 300 is detachably connected to the first connector 210. A mounting groove 500 is formed between the second connector 300 and the first connector 200 for mounting at least a portion of the first beam 110. Thus, the connection between the first connector 200 and the second connector 300 further enables the connection between the first beam 110 and the second beam 120, effectively simplifying the overall connection structure. This not only reduces the number of connection structures and nodes but also improves the stability and safety of the connection, and facilitates on-site installation.

[0071] In related technologies, the connection scheme using purlin brackets 011 (angle steel) and bolts and other connecting parts 012 to connect the first beam 110 and the second beam 120 requires drilling holes in the beams (first beam 110 and second beam 120) on site. Figure 3Drilling holes on the top surface of the second beam 120 or at other locations and adding connectors 012 would result in an uneven top surface of the second beam 120, affecting the installation effect of the photovoltaic modules. This application achieves the connection between the first beam 110 and the second beam 120 through the connection components, avoiding the problems of inconvenience, low efficiency, and poor photovoltaic module installation caused by drilling holes in the beams (first beam 110, second beam 120). It also effectively reduces assembly construction steps and improves installation quality and efficiency. Furthermore, using the connection components of this application to install the first beam 110 and the second beam 120 reduces the requirements for on-site construction conditions, allowing on-site construction without electrical wiring or drilling. This not only facilitates installation but also effectively reduces the requirements for manual construction skills, making the construction quality of the power station support structure controllable.

[0072] Reference Figures 4 to 7 In one embodiment, the snap-fit ​​portion 220 is tapered in the direction close to the first connecting portion 210.

[0073] Understandably, at least a portion of the snap-fit ​​portion 220 abuts against the groove wall of the first connecting groove 1201, and the outer diameter of the snap-fit ​​portion 220 gradually decreases towards the first connecting portion 210. This allows the first connecting member 200 to be more securely fixed within the first connecting groove 1201, achieving a self-locking effect. Besides facilitating the installation of the snap-fit ​​portion 220 within the first connecting groove 1201, it also facilitates the first connecting portion 210 extending out of the first connecting groove 1201 through its opening, thereby improving the stability and reliability of the actual assembly.

[0074] Reference Figure 4 In one embodiment, the snap-fit ​​portion 220 includes a first sidewall 221, a second sidewall 222 and a third sidewall 223 connected to the first sidewall 221 and the second sidewall 222. The third sidewall 223 is used to abut against the bottom wall of the first connecting groove 1201. The first sidewall 221 abuts against one of the groove walls of the first connecting groove 1201. The second sidewall 222 is inclined relative to the first sidewall 221 and is gradually moved closer to the first sidewall 221 in a direction away from the third sidewall 223.

[0075] The bottom wall is defined by the side wall of the first connecting groove 1201 facing its opening. The third side wall 223 abuts against the bottom wall of the first connecting groove 1201. The first side wall 221 abuts against one of the groove walls of the first connecting groove 1201. The second side wall 222 is inclined relative to the first side wall 221. This can help to disperse and transfer loads, reduce local stress concentration, improve safety, and prevent the first connector 200 from sliding along the groove wall of the first connecting groove 1201 or falling off when subjected to tension or other forces, thus providing stability for the overall structure.

[0076] Optionally, the first sidewall 221, the second sidewall 222, and the third sidewall 223 each have a first end and a second end, and the third sidewall 223 is connected between the second end of the first sidewall 221 and the second end of the second sidewall 222. The first sidewall 221 and the second sidewall 222 may be connected to each other or not connected to each other. When the first sidewall 221 and the second sidewall 222 are connected to each other, the first end of the first sidewall 221 and the first end of the second sidewall 222 are both connected to the snap-fit ​​part 220, and the two are set at an angle, so that the snap-fit ​​part 220 is reduced in the direction close to the first connecting part 210. When the first sidewall 221 and the second sidewall 222 are not connected to each other, the first end of the first sidewall 221 and the first end of the second sidewall 222 are set close to the snap-fit ​​part 220, and optionally the first connecting part 210 is set on the first sidewall 221, the second sidewall 222 or other sidewalls between them. The distance between the first sidewall 221 and the second sidewall 222 gradually decreases in the direction close to the first connecting part 210, so that the snap-fit ​​part 220 is reduced in the direction close to the first connecting part 210.

[0077] The second sidewall 222 is inclined relative to the first sidewall 221 and gradually approaches the first sidewall 221 in a direction away from the third sidewall 223. Optionally, the second sidewall 222 is inclined relative to the opening of the first connecting groove 1201. In this way, in addition to facilitating the snapping of the first connector 200 into the first connecting groove 1201, it can also reduce the influence of the external environment on the first connector 200 and the second beam 120, and prevent the intrusion of moisture, dust, etc., thereby improving the durability and service life of the overall structure. In addition, the inclined arrangement of the first sidewall 221 can further reduce the material used in the first connector 200 and reduce processing costs.

[0078] In other embodiments, when the snap-fit ​​portion 220 is not tapered in the direction near the first connecting portion 210, the second sidewall 222 can be configured to be perpendicular to the bottom wall of the first connecting groove 1201 and abut against another groove wall of the first connecting groove 1201; or, the second sidewall 222 can be configured to be inclined relative to the bottom wall of the first connecting groove 1201, with both ends abutting against the bottom wall and another groove wall of the first connecting groove 1201, respectively. The second sidewall 222 can abut against the groove wall of the first connecting groove 1201 near the first beam 110, or against the groove wall of the first connecting groove 1201 away from the first beam 110; this is not limited here.

[0079] Reference Figures 5 to 7 In one embodiment, the first connecting groove 1201 has a first rolled edge 121 at the groove opening, the snap-fit ​​part 220 includes a fourth side wall 224, the fourth side wall 224 fits against the first rolled edge 121, and the first connecting part 210 is connected to the fourth side wall 224.

[0080] The fourth sidewall 224 abuts against the first rolled edge 121, so that the first connector 200 and the first connecting groove 1201 fit tightly together, preventing the first connector 200 from shifting when subjected to external force, or even from coming out of the groove opening and detaching from the first connecting groove 1201, in order to further optimize the stability of the overall structure.

[0081] The fourth sidewall 224 is optionally disposed between the first end of the first sidewall 221 and the first end of the second sidewall 222. The first connecting portion 210 extends out of the first connecting groove 1201 and is optionally attached to the first rolled edge 121. Taking the second beam 120 as an example, which includes two opposing first wing plates 122 and a first web plate 123 connected between the two first wing plates 122, the first connecting groove 1201 is formed between the first web plate 123 and the two first wing plates 122. The opening of the first connecting groove 1201 is formed between the two first wing plates 122, and the groove width of the first connecting groove 1201 is determined by the distance between the two first wing plates 122. Each first wing plate 122 has a first rolled edge 121 on the side away from the first web plate 123. The first connector 200 is inserted into the first connecting groove 1201 through the end of the second beam 120. The first side wall 221 of the engaging part 220 abuts against one of the first wing plates 122, and the third side wall 223 of the engaging part 220 abuts against the first web plate 123. The first connecting part 210 is provided to extend out of the first connecting groove 1201 through the groove opening. In this way, the first connector 200 can be prevented from detaching from the first connecting groove 1201 through the groove opening, which would affect the stability and reliability of actual assembly and use.

[0082] Reference Figures 4 to 7 In one embodiment, at the connection of the third sidewall 223, the distance between the opposite sides of the first sidewall 221 and the second sidewall 222 is adapted to the groove width of the first connecting groove 1201.

[0083] Understandably, the snap-fit ​​portion 220 is tapered in the direction close to the first connecting portion 210. At the connection point of the third side wall 223, the maximum outer diameter of the snap-fit ​​portion 220 is determined by the distance between the opposite sides of the first side wall 221 and the second side wall 222. The distance between the opposite sides of the first side wall 221 and the second side wall 222 is not greater than the groove width of the first connecting groove 1201, so as to be suitable for installing the snap-fit ​​portion 220 in the first connecting groove 1201.

[0084] It should be noted that in other embodiments, when the snap-fit ​​portion 220 also has other sidewalls that abut against the groove wall of the first connecting groove 1201, the maximum outer diameter of the snap-fit ​​portion 220, determined by the plurality of sidewalls of the snap-fit ​​portion 220, is adapted to the size of the first connecting groove 1201.

[0085] Reference Figures 4 to 7In one embodiment, the snap-fit ​​portion 220 is provided with a cavity 225. The cavity 225 can reduce the amount of material used in the first connector 200 and reduce processing costs.

[0086] Reference Figures 8 to 10 , Figure 16 , Figure 18 In one embodiment, the cavity 225 extends through the snap-fit ​​portion 220 along the extension direction of the second beam 120.

[0087] Optionally, the cavity 225 is formed in the middle of the snap-fit ​​portion 220, and the cavity 225 can be any regular or irregular shape. Specifically, the cavity 225 can be formed in the middle of the snap-fit ​​portion 220, or it can be formed by multiple side walls of the snap-fit ​​portion 220. The cross-section of the cavity 225 can be rectangular, trapezoidal, or any other shape suitable for actual use.

[0088] Taking the cavity 225 formed by the multiple side walls of the snap-fit ​​portion 220 as an example, the cavity 225 can be a non-closed cavity formed by the first side wall 221, the second side wall 222, and the third side wall 223; or, when the snap-fit ​​portion 220 also includes a fourth side wall 224, the cavity 225 can be a closed cavity with a cross-section in the shape of a right trapezoid or the like, formed by the first side wall 221, the second side wall 222, the third side wall 223, and the fourth side wall 224. The shape of the cavity 225 formed by the snap-fit ​​portion 220 can be determined according to the structure of the snap-fit ​​portion 220, and is not limited here.

[0089] In some other alternative embodiments of this application, the first sidewall 221, the third sidewall 223, and the fourth sidewall 224 are in contact with the groove wall of the first connecting groove 1201. Specifically, at least one of the first sidewall 221, the third sidewall 223, and the fourth sidewall 224 may be provided with anti-slip ribs 3221 or other anti-slip structures to increase the friction between the first connector 200 and the groove wall of the first connecting groove 1201, prevent the first connector 200 from sliding relative to the first connecting groove 1201, and prevent the first connector 200 from sliding or coming out of the first connecting groove 1201 when subjected to force, so as to further improve the reliability and safety of the connection.

[0090] Reference Figures 8 to 14 In one embodiment of this application, the second connector 300 includes a circumferential portion 311 and two second connector portions 312 spaced apart and connected to the circumferential portion 311. The second connector portions 312 are connected to the first connector portion 210. The mounting groove 500 is formed between the two second connector portions 312 for overall installation of the first beam 110.

[0091] The second connector 300 can optionally be a clamp or other connection structure with an enclosing space. A mounting groove 500 is formed between the enclosing portion 311 and two second connectors 312 spaced apart from each other, facilitating the overall installation of the first beam 110. The width of the outer peripheral wall of the first beam 110 is determined by the maximum distance between the opposite sides of the first beam 110, and the distance between the two second connectors 312 is not less than the width of the outer peripheral wall of the first beam 110. This not only facilitates the installation of the first beam 110 but also allows for easy adjustment of the connection position between the first beam 110 and the second beam 120 to adapt to different installation requirements. The second connector 300 also provides a stable fixing point, making the connection between the first beam 110 and the second beam 120 more secure and enhancing the overall structural stability and wind and earthquake resistance.

[0092] The specific structure of the first connector 200 can be referred to the structure of the first connector 200 in the aforementioned embodiment, and will not be described in detail here.

[0093] Reference Figures 8 to 14 In one embodiment, the two second connecting portions 312 are connected to the circumferential portion 311 in a U-shape.

[0094] In some alternative embodiments of this application, the first beam 110 and the second beam 120 are arranged at an angle. There are two first connectors 200, which are respectively located on both sides of the second beam 120 corresponding to the positions of the first beam 110. In the assembled state, the two second connectors 312 on both sides of the circumferential portion 311 are respectively connected to the two first connectors 200 on both sides of the second beam 120 to form a stable overall structure. In this way, the first beam 110 and the second beam 120 can be effectively fixed, and the lateral resistance of the system can be enhanced, thereby improving the load-bearing capacity and stability of the entire support system. The U-shaped structure design allows for a certain adjustment space to accommodate adjusting the connection position of the first beam 110 and the second beam 120 and to adapt to different installation requirements and environmental conditions. By using clamps and other similar structures as the second connectors 300, the overall connection relationship is simple, which not only effectively simplifies the installation process but also further improves construction efficiency.

[0095] In other embodiments, the two second connecting portions 312 and the enclosing portion 311 may also be connected in an H-shape or an F-shape; this is not limited here.

[0096] Reference Figure 9As an example, the first connecting portion 210 is provided with a first connecting hole 211. Specifically, the portion of the first connecting portion 210 extending out of the first connecting groove 1201 is provided with the first connecting hole 211. The second connecting portion 312 of the second connecting member 300 is provided with a first thread 313 or other connecting position. The second connecting member 300 includes a first locking member 3141, a second locking member 3142, etc. The first locking member 3141, the second locking member 3142, etc., may optionally adopt a nut, connecting plate, or other connecting structure adapted to the connecting position. During assembly, a first locking member 3141 can be first installed on the second connecting part 312. The first locking member 3141 abuts against the second beam 120. After the second connecting part 312 passes through the first connecting hole 211 provided in the first connecting part 210, the first connecting member 200 is locked and fixed in the first connecting groove 1201 by assembling the second locking member 3142, thereby realizing the locking connection of the first connecting member 200, the second beam 120, and the second connecting member 300. Specifically, the relative distance between the first beam 110 and the second beam 120 can be adjusted by adjusting the positions of the first locking member 3141 and the second locking member 3142 on the second connecting part 312 to suit the assembly of beams of different sizes and meet the assembly requirements of different application scenarios.

[0097] Reference Figures 10 to 15 As a second example, to adapt to the needs of scenarios with large environmental loads, the connecting assembly also includes a third connector 400. The third connector 400 is used to engage with the side of the second beam 120 near the first beam 110 and to enclose at least a portion of the second beam 120. It also has a third connecting portion 410 protruding from the slot side of the first connecting groove 1201 onto the second beam 120. The first connecting portion 210 has a first connecting hole 211, and the third connecting portion 410 has a second connecting hole 430. The second connecting portion 312 passes through the first connecting hole 211 and the second connecting hole 430, and connects and fixes the first connector 200 and the third connector 400.

[0098] The third connector 400 is used in conjunction with the first connector 200 and the second connector 300 to effectively distribute the load and further optimize the stability and load-bearing capacity of the overall structure, so as to ensure that the second beam 120 will not bend or break when the support is subjected to a large load.

[0099] Reference Figure 15The portion of the first connecting part 210 extending out of the first connecting groove 1201 is provided with a first connecting hole 211. Optionally, the third connecting member 400 can be, but is not limited to, an L-shaped plate or other structural connecting members. Taking the third connecting member 400 as an example of using an L-shaped plate, the third connecting member 400 includes a first side plate 421 and a second side plate 422 that are connected to each other. When the second beam 120 includes two opposing first wing plates 122 and a first web plate 123 connected between the two first wing plates 122, the first side plate 421 abuts against the first web plate 123 of the second beam 120, and the second side plate 422 abuts against the first wing plate 122 that is close to the first beam 110. The third connecting part 410 is provided on the second side plate 422 and protrudes from the second beam 120 on one side of the groove of the first connecting groove 1201.

[0100] The second connecting portion 312 of the second connecting member 300 is provided with a first thread 313 or other connecting position. The second connecting member 300 includes a first locking member 3141, a second locking member 3142, etc. The first locking member 3141, the second locking member 3142, etc. can optionally adopt a nut or other connecting structure adapted to the connecting position. During assembly, the first locking member 3141 can be first set on the second connecting portion 312. The first locking member 3141 abuts against the third connecting portion 410. The second connecting portion 312 passes through the second connecting hole 430 in the third connecting portion 410 and the first connecting hole 211 in the first connecting portion 210 in sequence. After the second connecting portion 312 is assembled, the first connecting member 200 is locked and fixed in the first connecting groove 1201, thereby realizing the locking connection of the first connecting member 200, the second beam 120, and the second connecting member 300. Specifically, the relative distance between the first beam 110 and the second beam 120 can be adjusted by adjusting the positions of the first locking member 3141 and the second locking member 3142 on the second connecting part 312, so as to be suitable for assembling beams of different sizes and meet the assembly requirements of different application scenarios.

[0101] By combining the first connector 200, the second connector 300 (and the third connector 400) in the aforementioned examples 1 and 2, the number of connection structures and nodes can be reduced, and the stability and safety of the connection can be improved. This ensures the stability of the first beam 110 while resisting the impact of external loads on the photovoltaic modules and reducing local stress concentration. It also avoids the problems of inconvenience, low efficiency, and poor photovoltaic module installation caused by drilling holes in the first beam 110 and the second beam 120, effectively reducing assembly construction steps and improving installation quality and efficiency. Furthermore, using the connection components of this application to install the first beam 110 and the second beam 120 reduces the requirements for on-site construction conditions, allowing on-site construction without electrical wiring or drilling. This not only facilitates installation but also effectively reduces the requirements for manual construction techniques, making the construction quality of the power station support system controllable.

[0102] It should be noted that in the aforementioned embodiments, the first beam 110 can be, but is not limited to, C-shaped steel (with a C-shaped cross section, used for lightweight structures, etc.), L-shaped steel (with an L-shaped cross section, used for right-angle supports, etc.), U-shaped steel (with a U-shaped cross section, used for supports with high load-bearing requirements, such as channel steel, etc.), square tube, or round tube. The specific design can be determined according to actual conditions and is not limited here.

[0103] Reference Figures 16 to 22 In another embodiment of this application, the first beam 110 has a second connecting groove 1101, and a second rolled edge 111 is provided on the side of the second connecting groove 1101 near the second beam 120; the second connector 300 is provided with a slot 321, and the second connector 300 is used to be engaged with the second rolled edge 111 through the slot 321; the mounting groove 500 is formed between the slot 321 and the first connector 200, and is used for connecting the side of the first beam 110 near the second beam 120.

[0104] Optionally, the first beam 110 can be, but is not limited to, C-shaped steel (with a C-shaped cross section, used for lightweight structures, etc.), L-shaped steel (with an L-shaped cross section, used for right-angle supports, etc.), or U-shaped steel (with a U-shaped cross section, used for supports with high load-bearing requirements, such as channel steel, etc.); the specific design can be determined according to actual conditions and is not limited here.

[0105] Furthermore, taking the first beam 110 as having a C-shaped cross-section, and the first beam 110 including two opposing second flanges 112 and a second web 113 connecting the two second flanges 112 as an example, a second connecting groove 1101 is formed between the second web 113 and the two second flanges 112. The opening of the second connecting groove 1101 is formed between the two second flanges 112, and the groove width of the second connecting groove 1101 is determined by the distance between the two second flanges 112. Each second flange 112 has a rolled edge on the side away from the second web 113, and the rolled edge closest to the second beam 120 is designated as the second rolled edge 111.

[0106] The second connector 300 is snapped into the second rolled edge 111 of the second connecting groove 1101 via the slot 321. The slot 321 avoids drilling holes in the first beam 110, thereby reducing the drilling process and lowering the requirements for on-site construction conditions. On-site construction can be carried out without electrical wiring and drilling, which not only facilitates installation but also effectively reduces the requirements for manual construction skills, making the construction quality of the power station support controllable.

[0107] In this embodiment, the specific structure of the first connector 200 can be referred to the structure of the first connector 200 in the previous embodiment, and will not be described in detail here.

[0108] Reference Figures 17 to 22In one embodiment, the slot 321 has its inlet facing the first connector 200. A mounting groove 500 is formed between the slot 321 and the first connector 200 for connecting the side of the first beam 110 closest to the second beam 120. The slot 321's inlet facing the first connector 200 makes the connection between the first beam 110 and the second beam 120 more secure and enhances the overall structural stability and resistance to wind and earthquakes.

[0109] In other embodiments, other slots, snap-fit ​​components, or other connecting structures may be provided on other sides of the second connector 300, so that the second connector 300 can be connected to the first beam 110 through other connecting structures; the specific configuration can be determined according to actual conditions and is not limited here.

[0110] Reference Figures 20 to 22 In one embodiment, the second connector 300 has a first connecting plate 322, a second connecting plate 323, and a baffle 324. The first connecting plate 322 and the second connecting plate 323 are arranged opposite to each other and spaced apart. The baffle 324 is disposed between the first connecting plate 322 and the second connecting plate 323. A slot 321 is formed between the first connecting plate 322 and the baffle 324. The first connecting plate 322 is used to be installed in the second connecting groove 1101. The second connecting plate 323 and the baffle 324 are respectively used to abut against the adjacent sides of the second beam 120.

[0111] This configuration ensures a reliable connection between the second connector 300 and the second beam 120. The design of the first connecting plate 322 and the second connecting plate 323 reduces local stress concentration and improves the overall load-bearing capacity of the structure. The baffle 324 prevents the second connector 300 from sliding along the second beam 120 under external force, further increasing connection stability. The abutment connection, replacing drilling, reduces damage to the second beam 120, protecting its appearance and structural integrity. The design of the second connector 300 also allows for some adjustment of the connection position between the first beam 110 and the second beam 120, effectively improving connection flexibility and meeting assembly requirements in different application scenarios.

[0112] The second connecting plate 323 and the baffle 324 are respectively used to abut against the adjacent sides of the second beam 120. When the second beam 120 includes two opposing first wing plates 122 and a first web plate 123 connected between the two first wing plates 122, the second connecting plate 323 is used to abut against the first wing plate 122 of the second beam 120 near the first beam 110, and the baffle 324 is used to abut against the first web plate 123 of the second beam 120, so as to further realize the stable connection between the first beam 110 and the second beam 120.

[0113] The baffle 324 may optionally be configured as an I-shape or other plate having at least one side. In other embodiments, the baffle 324 may optionally be configured as an inverted L-shape, or a connecting plate may be additionally configured at other positions of the second connector 300, so that the second connector 300 is not limited to abutting against the adjacent two sides of the second beam 120; in addition, the second connector may be securely connected to the second beam 120 by additional locking structures such as screws configured at other positions of the second connecting plate 323, the baffle 324 or the second connector 300; the specific configuration may vary depending on the actual situation and is not limited here.

[0114] Reference Figures 16 to 22 In one embodiment, the second connector 300 is provided with a third connecting hole 325, which is located between the first connecting plate 322 and the second connecting plate 323 and is used to connect with the first connecting part 210.

[0115] The third connecting hole 325 may optionally be provided on the second connecting member 300 in the form of a hole, a connecting post, or the like. When the first connecting part 210 is provided with the first connecting hole 211, the connecting assembly also includes a connecting rod or other connecting structure. The third connecting hole 325 is connected to the first connecting part 210 through a connecting rod 326 (such as a screw) or other connecting member. The third connecting hole 325 (and the first connecting hole 211) may optionally be provided with a second thread. During assembly, the connecting rod 326 or other connecting member adapted to the second thread passes through the third connecting hole 325 in the second connecting member 300 and the first connecting hole 211 in the first connecting part 210 in sequence, and is locked and fixed outside the first connecting hole 211 and the third connecting hole 325 by a nut or other connecting structure, thereby achieving a tight connection between the first connecting member 200 and the second connecting member 300.

[0116] The design of the third connecting hole 325 provides a flexible connection method, which not only effectively improves the strength and fixation of the connection, but also avoids damage to the first beam 110 and the second beam 120 caused by drilling holes in them. This design not only simplifies the installation process and makes the structure more compact, but also reduces processing and transportation costs; it further reduces assembly construction procedures, improves installation quality and construction efficiency; and it also reduces the requirements for on-site construction conditions, enabling on-site construction without electrical wiring or drilling. This not only facilitates installation, but also effectively reduces the requirements for manual construction skills, making the construction quality of the power station support controllable.

[0117] In other embodiments, when the first connecting part 210 does not have a first connecting hole 211 or is not connected to the second connecting member 300 through the first connecting hole, the third connecting hole 325 can be connected to the first connecting part through a connecting rod or other connecting structure provided on the first connecting part 210 that is adapted to the third connecting hole 325; when the second connecting member 300 does not have a third connecting hole 325, the first connecting part 210 and the second connecting member 300 can be directly connected by a connecting rod or other connecting structure in a snap-fit ​​or other manner; the specific configuration can be determined according to actual conditions and is not limited here.

[0118] Reference Figures 19 to 22 In one embodiment, the first connecting plate 322 is provided with anti-slip ribs 3221. The anti-slip ribs 3221 can increase the friction between the second connecting member 300 and the groove wall of the second connecting groove 1101, prevent the second connecting member 300 from sliding relative to the second connecting groove 1101, and prevent the second connecting member 300 from sliding or dislodging from the second connecting groove 1101 when under force, thereby further improving the reliability and safety of the connection.

[0119] In other embodiments, anti-slip ribs may be provided on the second connecting plate 323, baffle 324 or other structures of the second connecting member 300 that contact the second beam 120 to increase friction.

[0120] Reference Figures 4 to 22 This application also proposes a photovoltaic support structure, which includes a first beam 110, a second beam 120, and a connecting component as described in the above embodiments, wherein the second beam 120 overlaps the first beam 110.
