Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically providing a main beam and photovoltaic support for a photovoltaic support. Background Technology

[0002] To reduce costs and increase efficiency, photovoltaic (PV) modules are becoming increasingly larger in power and size. Consequently, the tracking brackets supporting these modules are also becoming longer and wider. The increased length and width of the tracking brackets are primarily limited by the driving force and holding force of the drive system. Currently, multi-point drive is the main solution for most manufacturers. For single-axis systems, the bracket's main shaft is typically connected to multiple main shafts using rigid structures such as clamps and sleeves. Essentially, the entire row of brackets rotates around a single main shaft. However, multi-point drive systems are highly susceptible to system synchronization issues. If multiple drives become out of sync, it can cause the entire row of modules to stop, or even damage the modules.

[0003] Accordingly, there is a need in the field for a new main beam for photovoltaic supports to solve the problem of failure caused by asynchronous driving between multiple main shafts of existing photovoltaic supports. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of failure caused by asynchronous multi-point drive of the main shaft of the existing photovoltaic bracket.

[0005] In a first aspect, the present invention provides a main beam for a photovoltaic support structure, the main beam of which includes a first main beam, a second main beam, and a support base, wherein the end of the first main beam is connected to a first end shaft, and the end of the second main beam is connected to a second end shaft.

[0006] The first end shaft and the second end shaft are rotatably connected to both sides of the support base, respectively.

[0007] With the above technical solution, the structure of the left and right end shafts of this utility model is supported by the same support base and can rotate freely within the support base. The left and right end shafts are structurally independent, meaning that the rotation of the main beams on both sides is independent and does not affect each other. The torque of the main beams on both sides of the support base at the support base position is discontinuous, but the bending moment is continuous. This facilitates the modular design of the support system and the realization of long and narrow support structures, making the design more flexible, achieving standardized product design, and reducing the total number of parts.

[0008] In the optional technical solution of the main beam of the photovoltaic bracket mentioned above, a first bearing and a second bearing are respectively provided on both sides of the support base, the first end shaft is connected to the first bearing, and the second end shaft is connected to the second bearing.

[0009] With the above technical solution, the first end shaft and the second end shaft are rotatably connected by bearings and support seats, which makes the connection easier and provides reliable support.

[0010] In the optional technical solution of the main beam of the photovoltaic bracket mentioned above, a cavity is provided in the support base, the rear end of the first end shaft connected to the first bearing extends into the cavity, the rear end of the second end shaft connected to the second bearing extends into the cavity, and the first end shaft and the second end shaft are respectively provided with limiting members to limit the first end shaft and the second end shaft.

[0011] When the above technical solution is adopted, setting a cavity in the support base makes it easier to install the limiting component.

[0012] In the optional technical solution of the main beam of the photovoltaic bracket mentioned above, a first hollow flange and a second hollow flange extend from both sides of the support seat, respectively. The first hollow flange and the second hollow flange are respectively connected to the cavity. The first bearing is disposed in the first hollow flange and the second bearing is disposed in the second hollow flange.

[0013] With the above technical solution adopted, the first hollow flange and the second hollow flange are more convenient for bearing installation.

[0014] In a second aspect, the present invention also provides a main beam for a photovoltaic support structure. The main beam of the photovoltaic support structure includes a first main beam, a second main beam, and a support base. The end of the first main beam is connected to a first end shaft, and the end of the second main beam is connected to a second end shaft. The first end shaft and the second end shaft are rotatably connected to both sides of the support base. The two sides of the support base are respectively provided with a first groove and a second groove. The end of the first end shaft is provided with a first ball head that matches the first groove, and the end of the second end shaft is provided with a second ball head that matches the second groove, so that the first end shaft and the second end shaft can swing freely relative to the support base.

[0015] With the above technical solution, the ball-joint connection structure allows the left and right end shafts to not only rotate freely within the support base, but also to swing up, down, left, and right around the support base, thus achieving adaptability to complex terrains. Therefore, it not only connects the various drives to ensure that the rotation of each drive is independent, but also adapts to installation in complex terrains.

[0016] In the optional technical solution of the main beam of the photovoltaic bracket mentioned above, the support base includes a support base body, a first cover plate and a second cover plate. The first cover plate and the second cover plate are detachably connected to the support base body. The first cover plate and the support base body together form a first groove, and the second cover plate and the support base body together form a second groove.

[0017] With the above technical solution, the cover plate and the support base are detachably connected, which makes it easier to maintain the components.

[0018] In the optional technical solution of the main beam of the photovoltaic support mentioned above, the main beam of the photovoltaic support further includes a first main beam connector and a second main beam connector. The first end shaft is connected to the first main beam through the first main beam connector, and the second end shaft is connected to the second main beam through the second main beam connector.

[0019] With the above technical solution, the end shaft and the main beam are connected by the main beam connector, which makes it easier to disassemble and maintain the parts.

[0020] In a third aspect, the present invention also provides a photovoltaic support bracket, which includes the main beam of the photovoltaic support bracket described in any one of the above technical solutions.

[0021] In the optional technical solutions of the photovoltaic bracket mentioned above, the photovoltaic bracket further includes a column, and the bottom of the column and the support base are connected.

[0022] When the above technical solution is adopted, the column is used to support the support base, thereby providing support force for the two main beams on the left and right at the same time.

[0023] In the optional technical solutions of the photovoltaic bracket mentioned above, the photovoltaic bracket further includes a column connector, and the bottom of the column and the support base are connected by the column connector.

[0024] With the above technical solution, the column and the support base are connected by a column connector, which makes it easier to disassemble and maintain the parts.

[0025] Those skilled in the art will understand that the main beam of the photovoltaic support of this utility model includes a first main beam, a second main beam, and a support base. The first main beam is connected to a first end shaft at one end, and the second main beam is connected to a second end shaft at one end. The first end shaft and the second end shaft are rotatably connected to both sides of the support base, respectively.

[0026] With the above technical solution, the structure of the left and right end shafts of this utility model is supported by a support base and can rotate freely within the support base. The left and right end shafts are structurally independent, meaning that the rotation of the main beams on both sides is independent and does not affect each other. The torque of the main beams on both sides of the support base at the support base position is discontinuous, but the bending moment is continuous. This facilitates the modular design of the support system and the realization of long and narrow support structures, making the design more flexible, achieving standardized product design, and reducing the total number of parts.

[0027] The main beam structure of this invention can connect multiple drive systems while ensuring that each drive system rotates independently. This means that the drives can operate synchronously or asynchronously, completely avoiding the reliability issues caused by asynchronous multi-drive systems. Furthermore, it improves maintenance efficiency. When a drive module fails, the fault location can be directly identified without shutting down the entire row of supports for maintenance. Only that module needs to be stopped, and the supports of the remaining drive sections remain unaffected. This also effectively reduces power generation loss due to system maintenance.

[0043] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0044] It should be noted that in the description of this utility model, the term "above" is used interchangeably with "below". Terms such as “down,” “left,” “right,” and “inner,” indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are merely for descriptive purposes and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] Reference Figures 1 to 3 To address the problem of malfunctions caused by asynchronous multi-point drive of the main shaft in existing photovoltaic (PV) brackets, this invention provides a main beam for a PV bracket. The main beam includes a first main beam 11, a second main beam 21, and a support base 3. The first main beam 11 is connected to a first end shaft 12 at one end, and the second main beam 21 is connected to a second end shaft 22 at one end. The first end shaft 12 and the second end shaft 22 are rotatably connected to both sides of the support base 3, respectively.

[0047] The structure of this utility model, with its left and right end shafts disconnected, is supported by support base 3 and can rotate freely within the support base 3. The left and right end shafts are structurally independent, meaning the rotation of the main beams on both sides is independent and does not affect each other. The torque of the main beams on both sides of the support base 3 at the support base 3 position is disconnected, but the bending moment is continuous. This facilitates modular design of the support system and the realization of long-row supports, making the design more flexible, achieving standardized product design, and reducing the total number of parts.

[0048] The main beam structure of this invention can connect multiple drive systems while ensuring that each drive system rotates independently. This means that the drives can operate synchronously or asynchronously, completely avoiding the reliability issues caused by asynchronous multi-drive systems. Furthermore, it improves maintenance efficiency. When a drive module fails, the fault location can be directly identified without shutting down the entire row of supports for maintenance. Only that module needs to be stopped, and the supports of the remaining drive sections remain unaffected. This also significantly reduces power generation loss due to system maintenance.

[0049] This utility model also provides a photovoltaic bracket, as shown in the reference. Figure 1 , Figure 2 The photovoltaic support includes a main beam and a column 4. The column 4 is equipped with a column connector 41. The bottom of the column 4 and the support base 3 are connected by the column connector 41, which makes it easier to disassemble and maintain the parts.

[0050] In the first possible implementation:

[0051] Reference Figures 1 to 3 The main beam of the photovoltaic support includes a first main beam 11, a second main beam 21, and a support base 3. The end of the first main beam 11 is connected to a first end shaft 12, and the end of the second main beam 21 is connected to a second end shaft 22.

[0052] Reference Figure 7 The support base 3 has a first hollow flange 31 and a second hollow flange 32 on both sides, and a cavity 33 is provided inside the support base 3. The first hollow flange 31 and the second hollow flange 32 are respectively connected to the cavity 33. A first bearing 13 is provided inside the first hollow flange 31, and a second bearing 23 is provided inside the second hollow flange 32.

[0053] The first end shaft 12 is connected to the first bearing 13 and can rotate freely within the inner ring of the first bearing 13. The second end shaft 22 is connected to the second bearing 23 and can rotate freely within the inner ring of the second bearing 23. The column 4 provides support for the two main beams on the left and right.

[0054] The rear end of the first end shaft 12, connected to the first bearing 13, extends into the cavity 33, and the rear end of the second end shaft 22, connected to the second bearing 23, also extends into the cavity 33. Snap rings 15 are respectively provided on the first end shaft 12 and the second end shaft 22 to limit axial displacement of the two shafts. The cavity 33 structure facilitates the installation and removal of the snap rings 15.

[0055] However, it should be noted that those skilled in the art can replace the snap ring 15 with other limiting components, such as shaft end baffles, etc., according to actual needs, and all of these fall within the protection scope of this utility model.

[0056] Furthermore, the main beam of the photovoltaic support also includes a first main beam connector 14 and a second main beam connector 24. The first end shaft 12 and the first main beam 11 are connected by the first main beam connector 14.

[0057] Specifically, the first main beam connector 14 and the first main beam 11 are detachably connected by rivets or bolts. A first flange structure 121 is provided on the first end shaft 12, and a second flange structure 141 is provided on the first main beam connector 14. The first flange structure 121 and the second flange structure 141 are detachably connected by bolts to connect the first main beam connector 14 and the first end shaft.

[0058] The first main beam connector 14 and the second main beam connector 24 have the same structure. Correspondingly, the second main beam connector 24 and the second main beam 21 are detachably connected by bolts or rivets. A first flange structure 121 is provided on the second end shaft 22, and a second flange structure 141 is provided on the second main beam connector 24. The first flange structure 121 and the second flange structure 141 are detachably connected by bolts to connect the second main beam connector 24 and the second end shaft 22. This facilitates the removal of the end shaft from the main beam, making the photovoltaic support easier to maintain.

[0059] However, it should be noted that the connection method between the main beam connector and the main beam can be not only bolted or riveted, but also snap-fitted, welded, etc. Those skilled in the art can set the connection method between the main beam connector and the main beam according to actual needs. Furthermore, although the main beam connector and the end shaft are connected by a flange structure, this is not limiting. The flange structure can also be omitted, and the main beam connector and the end shaft can be directly bolted, riveted, or welded, etc. Those skilled in the art can set this according to actual needs, and all such designs fall within the protection scope of this utility model.

[0060] As the installed capacity of photovoltaic power stations continues to increase, land resources with good solar resources and flat terrain are becoming increasingly scarce. Land with complex terrain, such as mountains and hills, is becoming the primary site for photovoltaic power station construction. To adapt to installation environments with complex terrain, this utility model also provides a second possible implementation method:

[0061] Reference Figures 4 to 6 , Figure 8 and Figure 9 The main beams of the photovoltaic support system include a first main beam 11, a second main beam 21, and a support base 3. The end of the first main beam 11 is connected to a first end shaft 12, and the end of the second main beam 21 is connected to a second end shaft 22. The support base 3 includes a support base body 35, a first cover plate 341, and a second cover plate 342. The first cover plate 341 and the second cover plate 342 are respectively disposed on the top surface of the support base body 35 and are detachably connected to the support base body 35. The separate design of the cover plate and the support base facilitates the maintenance of components.

[0062] Optionally, the first cover plate 341 and the second cover plate 342 are detachably connected to the support body 35 by bolts. However, this utility model does not impose any restrictions on the connection method between the cover plate and the support body 35. The installation method can also be riveting or snap-fitting, etc. Those skilled in the art can set it according to actual needs, and all of them fall within the protection scope of this utility model.

[0063] The inner side of the first cover plate 341 and the support body 35 together form a first groove 343, and the inner side of the second cover plate 342 and the support body 35 together form a second groove 344.

[0064] Reference Figures 4 to 6 The end of the first main beam 11 is connected to the first end shaft 12, and the end of the second main beam 21 is connected to the second end shaft 22. The end of the first end shaft 12 is provided with a first ball head 122, and the end of the second end shaft 22 is provided with a second ball head 221.

[0065] The first ball head 122 and the first groove 343 are correspondingly matched, and the second ball head 221 and the second groove 344 are correspondingly matched. After the first ball head 122 is embedded in the first groove 343, it can swing freely within the first groove 343. After the second ball head 221 is embedded in the second groove 344, it can swing freely within the second groove 344.

[0066] The ball-joint connection structure allows the left and right end shafts to rotate freely within the support base 3, and also to swing up and down and left and right around the support base 3, thus achieving adaptability to complex terrains. It not only connects the various drives to ensure that each drive rotates independently, but also adapts to installation in complex terrains.

[0067] However, it should be noted that although the support base 3 is described as a split type in the second embodiment, those skilled in the art can also remove the first cover plate 341 and the second cover plate 342, and directly set the first groove 343 and the second groove 344 on the support base 3. Those skilled in the art can set it according to actual needs, and all of them fall within the protection scope of this utility model.

[0068] like Figure 9 As shown, the main beam of the photovoltaic support further includes a first main beam connector 14 and a second main beam connector 24. The first end shaft 12 and the first main beam 11 are connected by the first main beam connector 14.

[0069] Specifically, the first main beam connector 14 and the first main beam 11 are detachably connected by rivets or bolts. A first flange structure 121 is provided on the first end shaft 12, and a second flange structure 141 is provided on the first main beam connector 14. The first flange structure 121 and the second flange structure 141 are detachably connected by bolts to connect the first main beam connector 14 and the first end shaft.

[0070] The first main beam connector 14 and the second main beam connector 24 have the same structure. Correspondingly, the second main beam connector 24 and the second main beam 21 are detachably connected by bolts or rivets. A first flange structure 121 is provided on the second end shaft 22, and a second flange structure 141 is provided on the second main beam connector 24. The first flange structure 121 and the second flange structure 141 are detachably connected by bolts to connect the second main beam connector 24 and the second end shaft 22. This facilitates the removal of the end shaft from the main beam, making the photovoltaic support easier to maintain.

[0071] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
