Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, and in particular to bracing components and photovoltaic supports. Background Technology

[0002] A photovoltaic (PV) mounting system typically consists of a support rod assembly and a support frame. The support frame is positioned on top of the support rod assembly, and the PV modules are mounted on the support frame.

[0003] In related technologies, in order to improve the stability of the support frame, the photovoltaic bracket also includes a diagonal brace component, one end of which is rotatably connected to the support frame and the other end of which is rotatably connected to the support rod assembly.

[0004] However, the diagonal bracing members are only connected to the support frame and support rod assembly through a rotating connection at both ends. This connection structure cannot form a stable constraint. When wind force acts on the photovoltaic modules, the support frame will sway. Under the action of swaying for a long time, it is easy for the photovoltaic modules to fall apart. Utility Model Content

[0005] Therefore, it is necessary to provide a bracing component and photovoltaic bracket to address the problem that the bracing rod assembly cannot effectively suppress the swaying of the support frame.

[0006] A diagonal bracing member for connecting a first connecting member and a second connecting member that are interconnected, the diagonal bracing member comprising:

[0007] A diagonal brace assembly, one end of which is rotatably connected to the second connector;

[0008] The tensioning assembly has a first rotating part and a second rotating part arranged at intervals. The first rotating part is rotatably connected to the diagonal brace group, and the second rotating part is rotatably connected to the first connecting member. When the tensioning assembly rotates around the second rotating part, it can drive the first rotating part to swing.

[0009] A locking component is provided on the first connector, and the locking component is used to fix the tensioning component.

[0010] In one embodiment, the tensioning assembly includes a first connecting segment and a second connecting segment connected in sequence, the second rotating part is disposed at the connection position of the first connecting segment and the second connecting segment, and the first rotating part is disposed at the end of the first connecting segment away from the second connecting segment;

[0011] The locking component is used to lock the second connection segment.

[0012] In one embodiment, the locking assembly includes a first bolt and a second bolt, which abut against two opposite sides of the second connecting segment along the swing direction.

[0013] In one embodiment, the diagonal brace includes a clamp assembly for clamping onto the first connector;

[0014] The second rotating part is rotatably connected to the clamp assembly, and the locking component is disposed on the clamp assembly.

[0015] In one embodiment, the clamp assembly includes a first clamp body and a second clamp body rotatably connected, and two ears extending radially from the first clamp body and the second clamp body respectively, the second rotating part being rotatably connected to both ears simultaneously, and a second connecting section extending between the two ears;

[0016] The locking assembly includes a locking clamp, which is fitted onto the two ears. The locking clamp has threaded holes on both sides along the axial direction of the clamp assembly. The first bolt and the second bolt pass through the threaded holes to abut against the second connecting section.

[0017] In one embodiment, the second connecting segment gradually decreases in size along the axial direction of the clamp assembly, moving away from the first connecting segment.

[0018] In one embodiment, the first connecting segment and the second connecting segment are set at an obtuse angle.

[0019] In one embodiment, the diagonal brace further includes a triangular strut, one vertex of which is rotatably connected to the first connector, and the other two vertices of which are simultaneously fixedly connected to the second connector.

[0020] In one embodiment, the diagonal brace assembly is a telescopic rod.

[0021] A photovoltaic support bracket includes a first connector, a second connector, and a diagonal bracing member. The second connector is disposed at one end of the first connector and is used to support photovoltaic modules. One end of the diagonal bracing member is rotatably connected to the second connector. A tensioning member is rotatably connected to the first connector. A locking member is disposed on the first connector.

[0022] After the aforementioned diagonal bracing components, photovoltaic brackets, support rod assemblies, and support frames are interconnected, one end of the diagonal bracing assembly is first connected to the support frame. One end of the tensioning assembly is connected to the diagonal bracing assembly via a first rotating part, and the other end is connected to the support rod assembly via a second rotating part. Then, the tensioning assembly is rotated so that the first rotating part rotates around the second rotating part. When the first rotating part rotates, it can drive the diagonal bracing assembly to rotate, so that both ends of the diagonal bracing assembly are in a tensioned state. Then, the tensioning assembly is locked by the locking assembly, which can achieve a stable connection between the diagonal bracing components, the support frame, and the support rod assembly, enhance the stability of the entire photovoltaic system, and extend the service life of the photovoltaic bracket.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0036] See Figure 1 An embodiment of this application provides a diagonal bracing member for connecting a first connecting member and a second connecting member that are interconnected. The diagonal bracing member includes a diagonal bracing rod assembly 410, a tensioning assembly 420, and a locking assembly 430. One end of the diagonal bracing rod assembly 410 is rotatably connected to the second connecting member. The tensioning assembly 420 has a first rotating portion 423 and a second rotating portion 424 that are spaced apart. The first rotating portion 423 is rotatably connected to the diagonal bracing rod assembly 410, and the second rotating portion 424 is rotatably connected to the first connecting member. When the tensioning assembly 420 rotates around the second rotating portion 424, it can drive the first rotating portion 423 to swing. The locking assembly 430 is disposed on the first connecting member and is used to fix the tensioning assembly 420.

[0037] In this embodiment, the diagonal bracing member is used to connect the first and second connecting members, thereby enhancing the connection stiffness of the first and second connecting members through the principle of triangular stability and preventing deformation under stress. Specifically, in conjunction with... Figure 6 In the field of photovoltaic (PV) mounting systems, the first connector can be a support rod assembly 200, and the second connector is a support frame 300 mounted on the support rod assembly 200. The support frame 300 is used to install PV modules. Of course, in other fields, the bracing member can also be used to support other connection structures. For example, in the construction field, the first connector can be a steel column, and the second connector can be a steel beam; or in the field of machinery, the first connector can be a column, and the second connector can be a working platform. The following description focuses on its application in the PV field.

[0038] In this embodiment, after the support rod assembly 200 and the support frame 300 are connected to each other, one end of the diagonal brace group 410 is first connected to the support frame 300. One end of the tensioning assembly 420 is connected to the diagonal brace group 410 through the first rotating part 423, and the other end is connected to the support rod assembly 200 through the second rotating part 424. Then, the tensioning assembly 420 is rotated so that the first rotating part 423 rotates around the second rotating part 424. When the first rotating part 423 rotates, it can drive the diagonal brace group 410 to rotate so that both ends of the diagonal brace group 410 are in a tensioned state. Then, the tensioning assembly 420 is locked by the locking assembly 430, so that the diagonal brace member is stably connected to the support frame 300 and the support rod assembly 200, which enhances the stability of the entire photovoltaic system and extends the service life of the photovoltaic support.

[0039] In some embodiments, the tensioning assembly 420 includes a first connecting segment 421 and a second connecting segment 422 connected in sequence, a first rotating part 423 is disposed at the end of the first connecting segment 421 away from the second connecting segment 422; a locking assembly 430 is used to lock the second connecting segment 422, and a second rotating part 424 is located between the first rotating part 423 and the locking assembly 430.

[0040] In this embodiment, the second rotating part 424 is located between the first rotating part 423 and the locking assembly 430. That is, the tensioning assembly 420 acts as a lever arm, and the second rotating part 424 serves as the fulcrum. When the second connecting section 422 rotates, the first rotating part 423 causes the diagonal brace assembly 410 to swing around the second rotating part 424. When the locking assembly 430 locks the second connecting section 422, the first connecting section 421 is fixed, thereby putting the diagonal brace assembly 410 in a tensioned state. After the tensioning assembly 420 tensions both ends of the diagonal brace assembly 410, it effectively eliminates the misalignment caused by photovoltaic module installation errors, while also resisting the dual loads of gravity settlement and typhoon uplift, significantly improving the structural durability of the photovoltaic support under extreme weather conditions.

[0041] The support rod assembly 200 extends vertically, and the support frame 300 is located on top of the support rod assembly 200. The rotation axis of the first rotating part 423 and the rotation axis of the second rotating part 424 both extend horizontally, thereby causing the first rotating part 423 to drive the diagonal brace assembly 410 to swing up and down around the second rotating part 424.

[0042] Combination Figure 1 Furthermore, the locking assembly 430 includes a first bolt 431 and a second bolt 432, which abut against the two opposite sides of the second connecting section 422 along the swing direction.

[0043] In this embodiment, the first rotating part 423 drives the diagonal brace assembly 410 to swing up and down around the second rotating part 424, so that the first bolt 431 is located above the second connecting section 422 and abuts against the upper part of the second connecting section 422, and the second bolt 432 is located below the second connecting section 422 and abuts against the bottom of the second connecting section 422. That is, the first bolt 431 and the second bolt 432 clamp the second connecting section 422 in the vertical direction, thereby locking the entire tensioning assembly 420.

[0044] In some embodiments, combined with Figure 2 and Figure 3 The diagonal bracing component includes a clamp assembly 440, which is used to clamp onto the first connecting member; a second rotating part 424 is rotatably connected to the clamp assembly 440, and a locking component 430 is disposed on the clamp assembly 440.

[0045] In this embodiment, the entire diagonal brace is held tightly to the support rod assembly 200 by the clamp assembly 440. This facilitates the movement of the diagonal brace on the support rod assembly 200 by the clamp assembly 440, thereby supporting photovoltaic modules at different tilt angles. For example, when the photovoltaic module is placed at an angle, diagonal braces are connected to the higher and lower sides respectively. When the lengths of the two diagonal braces are equal, it is only necessary to move the connection positions of the clamp assemblies 440 of the two diagonal braces respectively to achieve support from one diagonal brace to the higher side of the photovoltaic module and from the other diagonal brace to the lower side.

[0046] In some embodiments, combined with Figure 2 , Figure 3 as well as Figure 5 The clamp assembly 440 includes a first clamp body 441 and a second clamp body 442 rotatably connected, and two ears 443 extending radially from the first clamp body 441 and the second clamp body 442 respectively. A second rotating part 424 is rotatably connected to both ears 443. A second connecting section 422 extends between the two ears 443. The locking assembly 430 includes a locking clamp 433, which is fitted onto the two ears 443. The locking clamp 433 has threaded holes 4331 on both sides along the axial direction of the clamp assembly 440. A first bolt 431 and a second bolt 432 pass through the threaded holes 4331 to abut against the second connecting section 422.

[0047] In this embodiment, combined with Figure 3The first hoop 441 and the second hoop 442 are respectively provided with a first ear 4431 and a second ear 4432 on opposite radially positioned sides. Locking bolts pass through the first ear 4431 and the second ear 4432 respectively to lock the clamp assembly 440. The length of the first ear 4431 is greater than the length of the second ear 4432. The tensioning assembly 420 and the locking assembly 430 are respectively connected to the first ear 4431.

[0048] Specifically, the first ear portion 4431 has two holes sequentially formed along its extension direction. One hole, closer to the first clamp 441, is used to install a locking bolt, and the other hole, farther from the first clamp 441, is used to install a second rotating part 424, which is a fulcrum shaft. The fulcrum shaft includes a head, a rotating shaft portion, and a bolt portion connected in sequence. The head and nut portions respectively clamp the rotating shaft portion in the middle. The rotating shaft portion has an internal threaded hole, and the bolt portion is threadedly connected to the threaded hole. The tensioning assembly 420 is rotatably connected to the rotating shaft portion.

[0049] Combination Figure 5 The locking clamp 433 is a rectangular sleeve that fits onto both ears 443. A second connecting section 422 is located between the two ears 443. A first bolt 431 passes through the threaded hole 4331 at the upper part of the locking clamp 433 to abut against the upper part of the second connecting section 422 between the two ears 443. A second bolt 432 passes through the threaded hole 4331 at the lower part of the locking clamp 433 to abut against the lower part of the second connecting section 422 between the two ears 443. A clearance groove 4332 is provided on the side of the locking clamp 433 near the first clamp body 441 to allow clearance from the bolts connecting the first clamp body 441 and the second clamp body 442.

[0050] In some embodiments, combined with Figure 1 and Figure 4 Along the direction away from the first connecting segment 421, the dimension of the second connecting segment 422 gradually decreases along the axial direction of the clamp assembly 440, and the locking assembly 430 is disposed at the smaller end of the second connecting segment 422.

[0051] In this embodiment, the second connecting segment 422 gradually decreases in size along the axial direction of the clamp assembly 440. The first bolt 431 and the second bolt 432 are located at the smaller end of the second connecting segment 422, which facilitates reducing the distance between the first bolt 431 and the second bolt 432, thereby reducing the overall size of the locking clamp 433 in the vertical direction.

[0052] In some embodiments, the first connecting segment 421 and the second connecting segment 422 are set at an obtuse angle.

[0053] In some embodiments, the angle between the first connecting segment 421 and the second connecting segment 422 is greater than 90° and less than 180°. The obtuse angle design allows the tensioning assembly 420 to form a longer lever arm when rotating, which can generate a larger tensioning force with a smaller operating force, thus significantly improving the tensioning efficiency.

[0054] In some embodiments, the diagonal bracing member further includes a triangular strut 411, one vertex of which is rotatably connected to the first connector, and the other two vertices of which are fixedly connected to the second connector.

[0055] In this embodiment, the triangular strut 411 is based on the inherent stability of a triangle. When the photovoltaic module is subjected to external forces such as wind load and snow load, the triangular structure can distribute the force to each connection point, significantly reducing the deformation and sway of the support frame 300 and improving the overturning resistance of the support frame 300.

[0056] In some embodiments, the diagonal brace assembly 410 is a telescopic rod.

[0057] In this embodiment, the diagonal brace group 410 is a telescopic rod. When the tilt angle of the photovoltaic module is large, the length difference between the diagonal brace group 410 connected to the side with a higher position of the photovoltaic module and the diagonal brace group 410 connected to the side with a lower position angle of the photovoltaic module is large. At this time, the diagonal brace group 410 is a telescopic rod, which can fix the photovoltaic module with a large tilt angle and improve the applicability of the diagonal brace group 410.

[0058] Combination Figure 6 An embodiment of this application also provides a photovoltaic bracket, including a support rod assembly 200, a support frame 300, and diagonal bracing members. The support frame 300 is disposed at one end of the support rod assembly 200 and is used to support photovoltaic modules. One end of the diagonal bracing rod assembly 410 is rotatably connected to the support frame 300. The tensioning assembly 420 is rotatably connected to the support rod assembly 200, and the locking assembly 430 is disposed on the support rod assembly 200.

[0059] In this embodiment, one end of the diagonal brace is rotatably connected to the support frame 300, and the other end is rotatably connected to the support rod assembly 200, which further enhances the support strength of the support rod assembly 200 to the support frame 300. The tensioning assembly 420 can adjust the tension of the diagonal brace to ensure a stable connection between the diagonal brace, the support frame 300, and the support rod assembly 200, thereby enhancing the stability of the entire photovoltaic system and extending the service life of the photovoltaic bracket.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
