[0002] Currently, the mainstream adjustable photovoltaic brackets on the market are mainly used for tracking brackets on large ground. This type of solution is mainly suitable for large ground and usually uses electric push rods or motor drives to achieve real-time angle adjustment.
[0003] The shortcomings and deficiencies of existing technologies: The mainstream solutions on the market are all suitable for large ground applications, but there is no good solution for residential applications. The electric angle adjustment mechanism will make the overall bracket too expensive and unsuitable for small installations. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a manually adjustable photovoltaic bracket, which solves the problem that adjustable photovoltaic brackets in the courtyard or on the roof of a household cannot be manually adjusted.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A manually adjustable photovoltaic bracket includes a support, a bearing seat mounted on top of the support, a main beam connected to a bearing inside the bearing seat, and a friction adjustment assembly mounted on the main beam and located on at least one side of the bearing axial direction. The friction adjustment assembly includes a friction ring push base fixed to the main beam, a friction ring axially movably connected to the friction ring push base, and a self-locking adjustment component connected to the friction ring push base. The self-locking adjustment component is used to push the friction ring to move axially relative to the friction ring push base and to frictionally lock the friction ring with the inner ring of the bearing.
[0007] Preferably, the self-locking adjusting component is a tightening bolt, and the friction ring push base is provided with a screw hole. The tightening bolt is connected to the screw hole, and when the tightening bolt rotates along the first direction, it pushes the friction ring relative to the friction ring push base to move.
[0008] Preferably, a guide structure is provided between the friction ring and the friction ring push base.
[0009] Preferably, the guiding structure includes a guide ring groove on the friction ring, and a guide protrusion is provided on the friction ring push base, the guide protrusion cooperating with the guide ring groove.
[0010] Preferably, the friction ring is provided with a tightening groove that mates with the tightening bolts; and / or, at least two tightening bolts are connected circumferentially along the friction ring pushing base.
[0011] Preferably, the main beam is made of square tubing, and the friction ring push base is provided with a square tubing sleeve that mates with the main beam; and / or, a friction adjustment assembly is provided on both axial sides of the bearing.
[0012] Preferably, purlins are spaced laterally along the main beam, the purlins are perpendicular to the main beam, and the purlins are connected to pressure block assemblies for fixing photovoltaic panels.
[0013] Preferably, the purlin is made of U-steel; and / or, the purlin is fixed to the main beam using U-bolts.
[0014] Preferably, the support includes a column and a foundation. The column is an H-shaped steel column and has a base plate at the bottom. The base plate is fixed to the pre-embedded anchor bolts in the foundation.
[0015] Preferably, the top of the column is provided with a top plate, the top plate is connected with a reinforcing rib, and the top plate is fixed to the bottom mounting plate of the bearing seat by bolts.
[0016] The present invention adopts the above technical solution and has the following beneficial effects:
[0017] 1. In the technical solution of this utility model, since the main beam is used to install photovoltaic panels and the main beam is rotatably supported on the bearing in the bearing seat, the main beam can be rotated relatively easily to change the angle of the photovoltaic panels and place them at a better power generation angle, thereby obtaining higher power generation and increasing the owner's income.
[0018] To lock the angle of the adjusted photovoltaic panel, a friction adjustment assembly is installed on the main beam, located on at least one side of the bearing's axial direction. This assembly includes a friction ring push base fixed to the main beam, a friction ring axially movably connected to the friction ring push base, and a self-locking adjustment component connected to the friction ring push base. The self-locking adjustment component is operable, pushing the friction ring axially relative to the friction ring push base and frictionally locking the friction ring against the bearing's inner ring. Because the self-locking adjustment component is self-locking, after adjustment, the friction ring remains in a locked state against the bearing's inner ring until the next adjustment, at which point the pushing force on the friction ring is released, separating the friction ring from the bearing's inner ring. This facilitates manual adjustment.
[0019] 2. The self-locking adjustment component can be a tightening bolt. The friction ring pushes the base with a screw hole, and the tightening bolt connects to the screw hole. When the tightening bolt rotates in the first direction, it pushes the friction ring relative to the friction ring, causing the base to move axially, making the friction ring move closer to the bearing. When the tightening bolt rotates in the second direction, it moves away from the friction ring, releasing the frictional force exerted by the friction ring on the inner ring of the bearing. Here, the first direction can be clockwise or counterclockwise, and the second direction is the opposite of the first direction. The tightening bolt is used as the self-locking adjustment component to facilitate manual adjustment, and the tightening bolt has a self-locking function, which can maintain the frictional locking force between the friction ring and the inner ring of the bearing for a long time. Under the premise of ensuring safety, the owner can manually adjust the bracket angle at any time.
[0020] 3. A guide structure is provided between the friction ring and the friction ring push base. The guide structure includes a guide ring groove on the friction ring and a guide protrusion on the friction ring push base. The guide protrusion and the guide ring groove are guided and engaged. Therefore, the guide structure guides the friction ring to move axially relative to the friction ring push base, so that the friction ring can be frictionally locked with the inner ring of the bearing.
[0021] 4. At least two tightening bolts are connected circumferentially along the friction ring push base to increase the frictional locking force between the friction ring and the bearing inner ring. Similarly, a friction adjustment assembly is provided on both axial sides of the bearing.
[0022] 5. The main beam can be made of square tubing, which has the advantages of being lightweight, high-strength, and low-cost. Correspondingly, the friction ring push base is equipped with a square tubing sleeve that mates with the main beam. Two opposite sides of the square tubing sleeve are connected to fastening bolts to fix it to the main beam, facilitating the fixing of both. Moreover, the purlins are U-shaped steel, perpendicularly intersecting the square tubing, making it easy to fix the purlins to the main beam.
[0023] 6. The support includes a column and a foundation. The foundation is a concrete structure, and the column is an H-beam steel column with a base plate at the bottom. The base plate is fixed to the foundation with pre-embedded anchor bolts. The top of the column has a top plate, and the base plate and top plate are connected by reinforcing ribs. The top plate is bolted to the bottom mounting plate of the bearing seat. This allows for the installation of concrete foundations on courtyards and rooftops, with pre-embedded anchor bolts used to install the column, and the bearing seat bolted to the top of the column, thus facilitating installation. The use of H-beam steel as the column offers advantages such as high bending resistance in all directions, simple construction, cost savings, and lightweight structure.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0040] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0043] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying 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.
[0044] like Figures 1 to 12 As shown, this utility model provides a manually adjustable photovoltaic bracket, mainly suitable for small-scale installations, such as residential photovoltaic systems, which can be installed in courtyards and on rooftops. It includes a support 1, a bearing seat 2 mounted on top of the support, a main beam 22 connected to a bearing 21 within the bearing seat, and a friction adjustment assembly 3 mounted on the main beam 22 and located on at least one side of the bearing 21 along its axial direction. Here, the length direction of the main beam is defined as transverse.
[0045] The friction adjustment assembly 3 includes a friction ring push base 32 fixed to the main beam, a friction ring 31 axially movably connected to the friction ring push base 32, and a self-locking adjustment component 33 connected to the friction ring push base 32. The self-locking adjustment component 33 is used to push the friction ring 31 to move axially relative to the friction ring push base 32 and to make the friction ring 31 frictionally lock with the bearing inner ring 211.
[0046] It is understandable that the friction ring 31 is frictionally locked with the end face of the bearing inner ring 211, and the mating surface is provided with a friction surface, such as friction texture. The friction ring can be made of conventional friction materials in the prior art.
[0047] In this embodiment, the main beam is used to install photovoltaic panels, and the main beam is rotatably supported on bearings within the bearing housing. Therefore, the main beam can be rotated relatively easily to change the angle of the photovoltaic panels, thereby obtaining higher power generation and increasing the owner's income.
[0048] To lock the angle of the adjusted photovoltaic panel, a friction adjustment assembly is installed on the main beam, located on at least one side of the bearing's axial direction. This assembly includes a friction ring push base fixed to the main beam, a friction ring axially movably connected to the friction ring push base, and a self-locking adjustment component connected to the friction ring push base. The self-locking adjustment component is operable, pushing the friction ring axially relative to the friction ring push base and frictionally locking the friction ring against the bearing's inner ring. Because the self-locking adjustment component is self-locking, after adjustment, the friction ring remains in a locked state against the bearing's inner ring until the next adjustment, at which point the pushing force on the friction ring is released, separating the friction ring from the bearing's inner ring. This facilitates manual adjustment.
[0049] In some embodiments, the self-locking adjusting component 33 is a tightening bolt, and the friction ring pushing base 32 has a screw hole 324, with the tightening bolt connected to the screw hole 324. When the tightening bolt rotates in the first direction, it pushes the friction ring 31 relative to the friction ring pushing base 32, causing the friction ring 31 to move closer to the bearing. When the tightening bolt rotates in the second direction, it moves away from the friction ring 31, releasing the frictional force exerted by the friction ring 31 on the inner ring 211 of the bearing. Here, the first direction can be clockwise or counterclockwise, and the second direction is the opposite of the first direction. The tightening bolt is used as a self-locking adjusting component to facilitate manual adjustment, and the tightening bolt has a self-locking function, which can maintain the frictional locking force between the friction ring and the inner ring of the bearing for a long time. Under the premise of ensuring safety, the owner can manually adjust the bracket angle at any time.
[0050] Furthermore, a guide structure is provided between the friction ring 31 and the friction ring push base 32. The guide structure includes a guide ring groove 312 on the friction ring and a guide protrusion 322 on the friction ring push base 32. The guide protrusion 322 and the guide ring groove 312 are guided and engaged. Therefore, the guide structure guides the friction ring to move axially relative to the friction ring push base, so that the friction ring can be frictionally locked with the inner ring of the bearing.
[0051] Furthermore, the friction ring 31 is provided with a tightening groove 313 that mates with the tightening bolt. In order to form a fit with the main beam, the inner ring of the friction ring is a square collar 311, and the tightening groove 313 is located between the square collar 311 and the guide ring groove 312.
[0052] In this embodiment, at least two tightening bolts are connected circumferentially along the friction ring pushing base. Four bolts are shown in the figure to increase the frictional locking force between the friction ring and the inner ring of the bearing. Similarly, a friction adjustment assembly 3 can be provided on both axial sides of the bearing.
[0053] Specifically, the main beam 22 is made of square tubing, which has the advantages of being lightweight, high-strength, and low-cost. The friction ring push base 32 is provided with a square tubing sleeve 321 that mates with the main beam 22. Two opposite sides of the square tubing sleeve 321 are connected to fastening bolts 34 to fix it to the main beam 22. Moreover, the purlin 4 is made of U-shaped steel and intersects perpendicularly with the square tubing, facilitating the fixing of the purlin to the main beam. The inner hole of the bearing inner ring 211 is a square hole, which mates with the main beam 22. In addition, a radial ring wall 323 is provided between the square tubing sleeve 321 and the guide convex ring 322, and a screw hole 324 is provided on the radial ring wall.
[0054] For the installation of photovoltaic panels, purlins 4 are arranged at transverse intervals on the main beam 22. The purlins 4 are perpendicular to the main beam 22 and are connected to a pressure block assembly 5 for fixing the photovoltaic panels 6.
[0055] Since it is mainly suitable for applications with small installed capacity, and considering the strength of the main beam, the number of photovoltaic panels installed should not be too large. Figure 1 As shown, four photovoltaic panels are installed in two rows and two columns, with the panels installed horizontally, meaning their length extends laterally. The columns are connected to the main beam at the midpoint, and four purlins are symmetrically positioned on both sides of the columns, ensuring balanced lateral force distribution on the main beam. The clamping assemblies are divided into edge clamping assemblies and center clamping assemblies, depending on their installation location. Edge clamping assemblies are used on both sides of the longitudinal direction to secure the photovoltaic panels, while center clamping assemblies are used between the frames of adjacent photovoltaic panels.
[0056] Referring to the structure in the prior art, the purlin 4 is made of U-steel; the purlin 4 is fixed by U-bolts 41 and a lower clamping plate 42 as the main beam. U-steel has advantages such as high strength, high toughness, good cold bending performance, and corrosion resistance. The lower clamping plate 42 is located below the bottom wall of the purlin, and the bottom wall of the purlin is provided with fixing holes 401. The fixing holes can be oblong holes. The two side posts of the U-bolt pass through two adjacent fixing holes, and after passing through the lower clamping plate, they are connected to nuts 43, thereby fixing the lower clamping plate 42 with nuts. In addition, the pressure block assembly 5 includes an upper pressure block and a lower pressure block, which are connected by pressure block bolts. The lower pressure block is installed inside the purlin, and the upper pressure block presses against the photovoltaic panel. For the side pressure block assembly, its upper pressure block is as follows... Figure 11 As shown, only one side needs to be provided with a flange for pressing the photovoltaic panel on the side. For the middle clamping block module, the upper clamping block is as follows: Figure 12 As shown, flanges are provided on both sides to press the photovoltaic panels on both sides together.
[0057] Specifically, the support 1 includes a column 12 and a foundation 10. The foundation 10 is a concrete structure, and the column 12 is an H-beam steel column with a base plate 121 at the bottom. The base plate is fixed to the pre-embedded anchor bolts 11 within the foundation. A top plate 123 is provided at the top of the column, and a reinforcing rib 122 connects the base plate and the top plate. The top plate is bolted to the bottom mounting plate of the bearing seat. This allows for the installation of concrete foundations on courtyards and rooftops, with pre-embedded anchor bolts used to install the column, and bolts used to fix the bearing seat at the top of the column, thus facilitating installation. The use of H-beam steel as the column offers advantages such as strong bending resistance in all directions, simple construction, cost savings, and lightweight structure.
[0058] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
