Description

Technical Field

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

[0002] In the field of photovoltaic power generation, the installation angle of photovoltaic modules directly affects the efficiency of solar energy reception and power generation revenue. Especially in high-latitude regions or complex lighting environments, flexibly adjusting the tilt angle of photovoltaic modules to adapt to the solar altitude angle at different seasons and times has become a key technical requirement for improving power generation. At the same time, the stability of the installation structure is the foundation for ensuring the long-term reliable operation of photovoltaic power plants, and a balance must be sought between adjustment function and structural stability.

[0003] In existing technologies, individual photovoltaic modules are typically installed using a fixed-angle support structure. This structure mainly consists of a support rod assembly and a support frame. The photovoltaic module is fixed to the support frame, and the connection stability is enhanced by diagonal bracing components. Traditional diagonal bracing components are mostly rigid rod assemblies hinged at both ends. One end is rotatably connected to the support frame, and the other end is connected to the support rod assembly, utilizing the principle of triangular stability to provide basic support.

[0004] However, while this fixed structure can meet the stability requirements under normal operating conditions, it is difficult to achieve angle adjustment of photovoltaic modules or the angle adjustment range is limited. Utility Model Content

[0005] Therefore, it is necessary to provide a single photovoltaic support system to address the problem that existing single photovoltaic support systems have difficulty adjusting the angle of photovoltaic modules or have a limited angle adjustment range.

[0006] A single photovoltaic (PV) mounting bracket for supporting a single PV module, the single PV mounting bracket comprising:

[0007] Base assembly for fixing to the ground or any fixed component;

[0008] A support rod assembly, one end of which is connected to the base assembly;

[0009] A support frame, wherein the other end of the support rod assembly is rotatably connected to the support frame, and the support frame is used to fix the photovoltaic module;

[0010] The diagonal bracing component includes a first diagonal brace, a clamp assembly, and a second diagonal brace connected in sequence. The end of the first diagonal brace away from the clamp assembly is rotatably connected to the support frame. The end of the second diagonal brace away from the clamp assembly is rotatably connected to the support rod assembly. The clamp assembly is fixedly connected to the outer wall of the first diagonal brace. The second diagonal brace can slide axially relative to the first diagonal brace. The clamp assembly is used to lock the second diagonal brace.

[0011] In one embodiment, the clamp assembly includes a first clamp and a second clamp coaxially connected, the first clamp being fixed outside the first diagonal brace, the second clamp being fixed outside the second diagonal brace, and the second clamp being axially capable of limiting and engaging with any position of the second diagonal brace.

[0012] In one embodiment, one of the first diagonal brace and the clamp assembly is provided with a limiting groove, and the other is provided with a protrusion, the protrusion cooperating with the limiting groove.

[0013] In one embodiment, a first limiting tooth is sequentially arranged along the axial direction on the outer wall of the second diagonal brace, and a second limiting tooth is sequentially arranged along the axial direction on the inner wall of the second clamp, wherein the first limiting tooth and the second limiting tooth mesh.

[0014] In one embodiment, the clamp assembly includes a rotating shaft, a first locking bolt, and a second locking bolt:

[0015] The first clamp includes a first clamping section and a second clamping section arranged along the axial direction of the clamp assembly, and the first clamping section covers the second clamping section. The first clamping section and the second clamping section are respectively provided with arc-shaped cavities with opposite openings.

[0016] The second clamp includes a third clamping section and a fourth clamping section arranged along the axial direction of the clamp assembly, and the third clamping section covers the fourth clamping section. The third clamping section and the fourth clamping section are respectively provided with arc-shaped cavities with opposite openings.

[0017] The rotating shaft passes sequentially through the first clamping section, the second clamping section, the third clamping section, and the fourth clamping section along the axial direction of the clamping assembly. The first locking bolt is used to lock the first clamping section onto the second clamping section, and the second locking bolt is used to lock the third clamping section onto the fourth clamping section.

[0018] In one embodiment, the clamp assembly includes a first connecting shaft and a second connecting shaft spaced circumferentially along the first clamp segment:

[0019] The first connecting shaft passes sequentially through the first clamping section and the third clamping section along the axial direction of the clamping assembly, and the second connecting shaft passes sequentially through the second clamping section and the fourth clamping section along the axial direction of the clamping assembly.

[0020] In one embodiment, the number of the diagonal bracing members is multiple, and at least one of the diagonal bracing members includes a tensioning component and a locking component. The tensioning component has a first rotating part and a second rotating part that are spaced apart. The first rotating part is rotatably connected to the second diagonal bracing rod, and the second rotating part is rotatably connected to the support rod group. When the tensioning component rotates around the second rotating part, it can drive the second diagonal bracing rod group to swing through the first rotating part. The locking component is used to be disposed on the support rod group and is used to fix the tensioning component.

[0021] In one embodiment, the support rod assembly is a telescopic rod.

[0022] In one embodiment, the base assembly includes a base and a first housing. The base and the first housing are respectively provided with a first arc-shaped groove. The first housing is also provided with a through hole communicating with the first arc-shaped groove. When the first housing is placed on the base, the two first arc-shaped grooves are interlocked to form a first spherical cavity. The bottom of the support rod assembly is provided with a first ball head, which is located in the first spherical cavity. The support rod assembly extends out of the through hole.

[0023] In one embodiment, the support rod assembly has a second ball head on the side away from the base assembly. The single photovoltaic bracket includes a second housing and a mounting base. The mounting base and the second housing are provided with a second arc-shaped groove. The second housing is provided with a second through hole communicating with the second arc-shaped groove. When the mounting base is placed on the second housing, the two second arc-shaped grooves engage with the spherical cavity. The second ball head is located in the spherical cavity, and the support rod assembly extends out of the second through hole.

[0024] The aforementioned single photovoltaic support unit has a base assembly that can be securely fixed to the ground or any fixed component, providing a stable installation foundation for the entire support rod assembly. One end of the support rod assembly is connected to the base assembly, and the other end is rotatably connected to the support frame, allowing the tilt angle of the photovoltaic modules on the support frame to be adjusted. The second diagonal brace of the diagonal bracing member can slide axially relative to the first diagonal brace, while the clamp assembly can lock the second diagonal brace at any position, allowing the length of the diagonal bracing member to be adjusted. This facilitates the support of photovoltaic modules with different tilt angles, while also meeting the support requirements for photovoltaic modules with large tilt angles.

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. 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.

[0047] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are 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 and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] 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.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] 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. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0051] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0052] In related technologies, when photovoltaic modules are tilted (i.e., the support frame is tilted), the force on the support rod assembly is uneven, causing instability in the center of gravity of the entire single photovoltaic support structure. Under wind force, the photovoltaic modules are easily blown over. Therefore, diagonal bracing components can be used to support the support frame. Specifically, a first diagonal bracing component is set on the side of the support frame with higher height, and a second bracing component is set on the side of the support frame with lower height. The ends of the first and second diagonal bracing components away from the support frame are connected to the support rod assembly. The first diagonal bracing component provides tension, and the second diagonal bracing component provides pushing force. This helps to ensure uniform force on both sides of the support frame, thereby improving the stability of the entire single photovoltaic support structure. However, when the tilt angle of the photovoltaic module changes significantly, the required length of the diagonal bracing component also changes significantly. A diagonal bracing component with a fixed length will limit the tilt angle of the photovoltaic module, preventing the photovoltaic module from being adjusted to a large tilt angle.

[0053] See Figure 1 and Figure 2 An embodiment of this application provides a single photovoltaic bracket, which is used to support a single photovoltaic module 500. The single photovoltaic bracket includes a base assembly 100, a support rod assembly 200, a support frame 300, and a diagonal brace 400. The base assembly 100 is used to fix it to the ground or any fixed object; one end of the support rod assembly 200 is connected to the base assembly 100; the other end of the support rod assembly 200 is rotatably connected to the support frame 300, which is used to fix the photovoltaic module 500; the diagonal brace 400 includes a first diagonal brace 450, a clamp assembly 460 and a second diagonal brace 470 connected in sequence, the end of the first diagonal brace 450 away from the clamp assembly 460 is rotatably connected to the support frame 300, the end of the second diagonal brace 470 away from the clamp assembly 460 is rotatably connected to the support rod assembly 200, the clamp assembly 460 is fixedly connected to the outer wall of the first diagonal brace 450, the second diagonal brace 470 can slide axially relative to the first diagonal brace 450, and the clamp assembly 460 is used to lock the second diagonal brace 470.

[0054] In this embodiment, the base assembly 100 can be firmly fixed to the ground or any fixed component, providing a stable installation foundation for the entire support rod assembly 200. One end of the support rod assembly 200 is connected to the base assembly 100, and the other end is rotatably connected to the support frame 300, allowing the tilt angle of the photovoltaic module 500 on the support frame 300 to be adjusted. The second diagonal brace 470 of the diagonal brace member 400 can slide axially relative to the first diagonal brace 450, while the clamp assembly 460 can lock the second diagonal brace 470 at any position, so that the length of the diagonal brace member 400 can be adjusted, thereby facilitating the support of photovoltaic modules 500 with different tilt angles and meeting the support requirements of photovoltaic modules 500 with large tilt angles.

[0055] In some embodiments, the base assembly 100 includes a base 110 and a first housing 120. The base 110 and the first housing 120 are respectively provided with first arc-shaped grooves. The first housing 120 is also provided with a through hole communicating with the first arc-shaped grooves. When the first housing 120 covers the base 110, the two first arc-shaped grooves engage with the first spherical cavity. The bottom of the support rod assembly 200 is provided with a first ball head 140, which is located in the first spherical cavity. The support rod assembly 200 extends out of the through hole.

[0056] In this embodiment, after the first housing 120 is placed on the base 110, it can be locked onto the base 110 using bolts. The base assembly 100 is fixed on any plane or inclined surface, making it easy to install the base at any location on a mountain. Furthermore, the support rod assembly 200 is fixed within the first spherical cavity via the first ball joint 140. The first ball joint 140 can rotate 360° around the axis of the support rod assembly 200 within the first spherical cavity. This flexible connection method allows the support frame 300 to rotate more freely in space, providing ample space for multi-angle adjustment of the photovoltaic module 500, enabling the photovoltaic module 500 to be adjusted in all directions.

[0057] The surface of the first ball head 140 is provided with a rough structure, for example, the first ball head 140 is a knurled sandblasted first ball head 140, in order to increase the friction between the first ball head 140 and the first spherical structure and the second spherical structure.

[0058] In other embodiments, in applications where the ground or the surface of the fixing component is flat, there is no need to adjust the tilt angle of the support rod assembly 200. That is, only a screw hole needs to be opened on the base assembly 100, and the bottom of the support rod assembly 200 can be directly threaded into the screw hole, which is convenient for installation.

[0059] Furthermore, in combination Figure 3 The clamp assembly 460 includes a first clamp 461 and a second clamp 462 coaxially connected. The first clamp 461 is fixed outside the first diagonal brace 450, and the second clamp 462 is fixed outside the second diagonal brace 470. The second clamp 462 can be limited and matched with any position of the second diagonal brace 470 along the axial direction.

[0060] In this embodiment, the clamp assembly 460 includes a first clamp 461 and a second clamp 462 coaxially connected. The first clamp 461 is fixed outside the first diagonal brace 450, and the second clamp 462 is fixed outside the second diagonal brace 470. The second clamp 462 can be axially limited and engaged with any position of the second diagonal brace 470. When it is necessary to adjust the angle of the photovoltaic module 500, the second diagonal brace 470 can be flexibly slid to change the total length of the diagonal brace component 400. Then, the second clamp 462 is used to lock the second diagonal brace 470, thereby completing the adjustment of the length of the diagonal brace component 400.

[0061] Specifically, in combination Figure 3 and Figure 4 One of the first diagonal brace 450 and the clamp assembly 460 is provided with a limiting groove 451, and the other is provided with a protrusion 4611, which cooperates with the limiting groove 451.

[0062] In one embodiment, a limiting groove 451 is formed on the first diagonal brace 450, and a protrusion 4611 is provided on the clamp assembly 460. The protrusion 4611 cooperates with the limiting groove 451 to fix the clamp assembly 460 to the outer wall of the first diagonal brace 450. Specifically, an annular limiting groove 451 is formed on the outer wall of the first diagonal brace 450, and an annular protrusion 4611 is provided on the inner wall of the clamp assembly 460. When the clamp assembly 460 is locked, the annular protrusion 4611 is engaged in the annular limiting groove 451 to connect the clamp assembly 460 to the first diagonal brace 450.

[0063] In another embodiment, the first diagonal brace 450 is provided with a protrusion 4611, and the clamp assembly 460 is provided with a limiting groove 451. The protrusion 4611 and the limiting groove 451 cooperate to fix the clamp assembly 460 to the outer wall of the first diagonal brace 450.

[0064] In some embodiments, a first limiting tooth 471 is sequentially arranged along the axial direction on the outer wall of the second diagonal brace 470, and a second limiting tooth 4621 is sequentially arranged along the axial direction on the inner wall of the second clamp 462, and the first limiting tooth 471 and the second limiting tooth 4621 mesh with each other.

[0065] In this embodiment, when the second clamp 462 is clamped onto the second diagonal brace 470, the first limiting tooth 471 on the inner side of the second clamp 462 engages with the second limiting tooth 4621 on the second diagonal brace 470, thereby locking the second diagonal brace 470. Specifically, limiting racks are provided on opposite radial sides of the second diagonal brace 470. Each limiting rack includes multiple first limiting teeth 471 arranged sequentially along the axial direction. The first limiting teeth 471 are triangular teeth, and correspondingly, the second limiting teeth 4621 are also triangular teeth.

[0066] In some embodiments, combined with Figures 5-7 The clamp assembly 460 includes a rotating shaft 463, a first locking bolt 464, and a second locking bolt 465. The first clamp 461 includes a first clamping section 4612 and a second clamping section 4613 arranged axially along the clamp assembly 460, with the first clamping section 4612 covering the second clamping section 4613. The first clamping section 4612 and the second clamping section 4613 are respectively provided with arc-shaped cavities with opposite openings. The second clamp 462 includes a third clamping section 4622 and a fourth clamping section 4623 arranged axially along the clamp assembly 460, with the third clamping section 4622 covering the second clamping section 4613. The tightening section 4622 covers the fourth clamping section 4623. The third clamping section 4622 and the fourth clamping section 4623 are respectively provided with arc-shaped cavities with opposite openings. The rotating shaft 463 passes through the first clamping section 4612, the second clamping section 4613, the third clamping section 4622 and the fourth clamping section 4623 in sequence along the axial direction of the clamping assembly 460. The first locking bolt 464 is used to lock the first clamping section 4612 onto the second clamping section 4613, and the second locking bolt 465 is used to lock the third clamping section 4622 onto the fourth clamping section 4623.

[0067] In this embodiment, the first clamping section 4612, the second clamping section 4613, the third clamping section 4622, and the fourth clamping section 4623 are sequentially connected by a rotating shaft 463, allowing the first clamping section 4612 to rotate relative to the second clamping section 4613, thus enabling it to open or close onto the second clamping section 4613. When the first clamping section 4612 closes onto the second clamping section 4613, the arcuate cavity on the first clamping section 4612 and the arcuate cavity on the second clamping section 4613 merge into a circular through hole, facilitating clamping around the first diagonal brace 450. The first clamping section 4612 and the second clamping section 4613 can be locked together by a first locking bolt 464.

[0068] Specifically, the inner diameter of the arc-shaped cavity on the first clamping section 4612 is smaller than the inner diameter of the arc-shaped cavity on the second clamping section 462. This is equivalent to having a protrusion 4611 inside the first clamping section 461, so that the first clamping section 461 can cooperate with the limiting groove 451 on the first diagonal brace 450, thereby restricting the first clamping section 461 from moving axially through the limiting groove 451.

[0069] Similarly, the first clamping section 4612, the second clamping section 4613, the third clamping section 4622, and the fourth clamping section 4623 are sequentially connected by a rotating shaft 463, allowing the third clamping section 4622 to rotate relative to the fourth clamping section 4623, thus enabling it to open or close onto the fourth clamping section 4623. When the third clamping section 4622 closes onto the fourth clamping section 4623, the arcuate cavity on the third clamping section 4622 and the arcuate cavity on the fourth clamping section 4623 merge into a circular through hole, facilitating clamping around the second diagonal brace 470. The third clamping section 4622 and the fourth clamping section 4623 can be locked together using a second locking bolt.

[0070] The first locking bolt 464 and the second locking bolt 465 are arranged sequentially along the circumference of the clamp assembly 460, and the first locking bolt 464 is located at one end of the rotating shaft 463 along the radial direction of the clamp assembly 460.

[0071] Furthermore, the clamp assembly 460 includes a first connecting shaft 466 and a second connecting shaft 467 spaced apart along the axial direction of the first clamp 461 segment. The first connecting shaft 466 passes sequentially through the first clamping segment 4612 and the third clamping segment 4622 along the axial direction of the clamp assembly 460, and the second connecting shaft 467 passes sequentially through the second clamping segment 4613 and the fourth clamping segment 4623 along the axial direction of the clamp assembly 460.

[0072] In this embodiment, the first clamping section 4612, the second clamping section 4613, the third clamping section 4622, and the fourth clamping section 4623 are connected sequentially by a rotating shaft 463. At the same time, the first connecting shaft 466 connects the first clamping section 4612 and the third clamping section 4622, and the second connecting shaft 467 connects the second clamping section 4613 and the fourth clamping section 4623. That is, the first connecting shaft 466 can increase the connection stability of the first clamping hoop 461 and the second clamping hoop 462.

[0073] Combination Figure 2 and Figure 8 In some embodiments, there are multiple diagonal bracing members 400, and at least one diagonal bracing member 400 includes a tensioning component 420 and a locking component 430. The tensioning component 420 has a first rotating part 423 and a second rotating part 424 that are spaced apart. The first rotating part 423 is rotatably connected to the second diagonal bracing rod 470, and the second rotating part 424 is rotatably connected to the support rod assembly 200. When the tensioning component 420 rotates around the second rotating part 424, it can drive the second diagonal bracing rod 470 to swing through the first rotating part 423. The locking component is used to be mounted on the support rod assembly 200 and is used to fix the tensioning component 420.

[0074] In some embodiments, combined with Figure 1The support frame 300 is inclinedly disposed on the support rod assembly 200. The support rod assembly 200 has a first side and a second side, and the horizontal height of the first side is greater than the horizontal height of the second side. The plurality of diagonal bracing members 400 include at least a first diagonal bracing member 481 and a second diagonal bracing member 482. The first diagonal bracing member 481 is rotatably connected to the first side, and the second diagonal bracing member 482 is rotatably connected to the second side. The first diagonal bracing member 481 includes a tensioning assembly 420 and a locking assembly.

[0075] In this embodiment, when installing the diagonal brace 400, firstly, the second diagonal brace 470 of the first diagonal brace 481 is rotatably connected to the support rod assembly 200. Then, the length of the first diagonal brace 481 is adjusted, and then the first diagonal brace 450 of the first diagonal brace 481 is rotatably connected to the support frame 300. Next, the second diagonal brace 482 is installed, and then the second diagonal brace 482 is rotatably connected to the support rod assembly 200. Next, adjust the length of the second diagonal brace 482, and then rotatably connect the first diagonal brace 450 of the second diagonal brace 482 to the support frame 300. Then, rotate the tensioning component 420 of the second diagonal brace 482 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 second diagonal brace 482 to rotate, so that both ends of the second diagonal brace 482 are in a tensioned state, and at the same time, the first diagonal brace 481 is also in a tensioned state. Finally, lock the tensioning component 420 by the locking component, so as to achieve a stable connection between the second diagonal brace 482, the support frame 300, and the support rod assembly 200, enhance the stability of the entire photovoltaic system, and extend the service life of the photovoltaic bracket.

[0076] Specifically, 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. A clamp 440 is provided at the end of the second diagonal brace 470 away from the first diagonal brace 450. The clamp 440 is fastened to the support rod assembly 200. The clamp 440 has two ears 443 extending radially. The second rotating part 424 is rotatably connected to the two ears 443, and the second connecting segment 422 extends into the space between the two ears 443.

[0077] The locking assembly 430 includes a locking clamp 433, which is fitted onto two ears 443. The locking clamp 433 has threaded holes 4331 on both sides along the axial direction of the clamp 440. The first bolt 431 and the second bolt 432 pass through the threaded holes 4331 to abut against the second connecting section 422.

[0078] Of course, in other embodiments, combined Figure 15 The diagonal bracing member 400 can also be four. In this case, the clamp 440 is provided with four pairs of ears 443, which are used to connect the four diagonal bracing members 400 respectively. Specifically, two of the diagonal bracing members 400 are provided with tensioning components 420 and locking components 430, while the other two diagonal bracing members 400 are not provided with tensioning components 420 and locking components 430.

[0079] In some embodiments, combined with Figure 1 and Figure 9 The support rod assembly 200 has a second ball head 600 on the side away from the base assembly 100. The single photovoltaic bracket includes a second housing 610 and a mounting base 620. The mounting base 620 and the second housing 610 have a second arc-shaped groove 621. The first housing 120 has a second through hole communicating with the second arc-shaped groove 621. When the mounting base 620 covers the second housing 610, the two second arc-shaped grooves 621 are fastened to form a spherical cavity. The second ball head 600 is located in the spherical cavity. The support rod assembly 200 extends out of the second through hole. The mounting base 620 and the second housing 610 are fixed by bolts.

[0080] During installation, first, the second housing 610 is fitted onto the support rod assembly 200, that is, the support rod assembly 200 extends out of the second through hole. Then, the second housing 610 is pre-fixed to the mounting base 620 by bolts. At this time, the second ball head 600 is located in the spherical cavity. Rotate the support frame 300 to the preset angle, and then fix the second housing 610 to the mounting base 620 by bolts.

[0081] The surfaces of the first ball head 140 and the second ball head 600 are provided with a rough structure. For example, both the first ball head 140 and the second ball head 600 are knurled and sandblasted ball heads to increase the friction between the ball head and the inner wall of the spherical cavity.

[0082] Furthermore, in combination Figure 10 The support frame 300 includes a frame 310 and two intersecting fixing rods 320 located within the frame 310. Each fixing rod 320 has an elongated hole. The mounting base 620 is a disc-shaped structure with multiple mounting holes on its periphery. Screws are used to pass through the mounting holes of the disc-shaped structure and the elongated holes on the fixing rods 320 to fix the mounting base 620 to the support frame 300. A second arc-shaped groove 621 is formed at the bottom of the disc-shaped structure.

[0083] In some embodiments, combined with Figure 11The support frame 300 includes a pressure block 330 and a fourth locking bolt 340. The pressure block 330 is pressed onto the frame 510 of the photovoltaic module 500, and the fourth locking bolt 340 is used to pass through the pressure block 330 and the frame 510 in sequence to fix the frame 510 to the support frame 300.

[0084] In some embodiments, the diagonal bracing member 400 further includes a triangular strut 411, one vertex of which is rotatably connected to the support rod assembly 200, and the other two vertices of which are fixedly connected to the support frame 300.

[0085] In some embodiments, combined with Figures 12-14 The support rod assembly 200 is a telescopic rod, allowing direct adjustment of the photovoltaic module's height as needed. Specifically, the support rod assembly 200 includes a female support rod 210, a male support rod 220, and a locking mechanism 230. A portion of the male support rod 220 is inserted into the female support rod 210, and the insertion depth is adjustable. The locking mechanism 230 is located radially between the male support rod 220 and the female support rod 210 to lock them together. The end of the female support rod 210 furthest from the male support rod 220 is connected to the base assembly.

[0086] The locking mechanism 230 includes a locking sleeve 231 and a locking clamp 232. The locking sleeve 231 is fixed to the inner side of the female support rod 210, and the locking clamp 232 is sleeved on the outer side of the male support rod 220 and can slide along the axial direction of the male support rod 220. The locking sleeve 231 is used to sleeve on the outer side of the locking clamp 232, and the inner diameter of the locking sleeve 231 and / or the outer diameter of the locking clamp 232 gradually changes along the insertion direction of the male support rod 220, so that the locking sleeve 231 and the locking clamp 232 move radially relative to each other and press the male support rod 220.

[0087] The support rod assembly 200 also includes a clamping mechanism 240, which is disposed on one side of the locking mechanism 230 along the insertion direction of the sub-support rod 220. The clamping mechanism 240 is disposed between the inner wall of the mother support rod 210 and the outer wall of the sub-support rod 220, and the outer wall of the clamping mechanism 240 abuts against the inner wall of the mother support rod 210 and the inner wall of the clamping mechanism 240 abuts against the outer wall of the sub-support rod 220.

[0088] The clamping mechanism 240 includes a clamping outer sleeve 241 and a clamping inner sleeve 242. The clamping outer sleeve 241 is fixed inside the mother support rod 210, and the clamping inner sleeve 242 is sleeved outside the son support rod 220. The clamping outer sleeve 241 is sleeved outside the clamping inner sleeve 242, and the inner diameter of the clamping outer sleeve 241 and / or the outer diameter of the clamping inner sleeve 242 gradually changes along the insertion direction of the son support rod 220, so that the clamping outer sleeve 241 and the clamping inner sleeve 242 move radially relative to each other and clamp the son support rod 220.

[0089] Of course, the support rod assembly 200 can also be telescopic in other ways. For example, multiple through holes are provided on the sub-support rod 220 at intervals along the axial direction. When bolts are inserted into different through holes and fixed to the mother support rod 210, the length of the support rod assembly 200 can be adjusted.

[0090] 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.

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.
