[0045] Distributed photovoltaic power stations are typically installed in a fixed manner on color-coated steel roofs. However, some manufacturing companies may emit dust or gases that can adversely affect the roof and exacerbate corrosion of the steel tiles. Furthermore, fixed-mounted photovoltaic systems are not conducive to future maintenance of the steel roofs, as they require dismantling the system before maintenance, which is time-consuming and labor-intensive.

[0046] In order to facilitate the maintenance of a roof equipped with a photovoltaic power station, the present application proposes a photovoltaic bracket.

[0047] Please refer to Figures 1 to 6 In one embodiment of the present application, the photovoltaic bracket includes a column 100, a connecting beam 200 and a support assembly 300; at least two connecting beams 200 are relatively provided and connected to the column 100; the two ends of the support assembly 300 are movably connected to at least two connecting beams 200 so as to be able to slide in the length direction of the connecting beam 200.

[0048] The column 100 is used to be installed on the roof, and it can be connected to the roof by welding or riveting. There can be one, two, or more columns 100. It can be understood that when there are multiple columns 100, the support of the column 100 to the connecting beam 200 is more stable and more balanced. The connecting beam 200 refers to a connector used to connect several columns 100, and is used to support the photovoltaic panel assembly 500 together with the support assembly 300. When the connecting beam 200 is connected to the column 100, it can be connected to the end face of the column 100 away from the roof, or to the side wall of the end of the column 100 away from the roof. The connecting beam 200 can be connected to the column 100 by welding, riveting or bolting. The support assembly 300 is mainly used to support the photovoltaic panel assembly 500. The two ends of the support assembly 300 are respectively connected to at least two connecting beams 200. After the support assembly 300 is subjected to the gravity of the photovoltaic panel assembly 500, it can be transmitted to the column 100 through the connecting beams 200, thereby ensuring that the photovoltaic panel assembly 500 has better support stability.

[0049] By connecting the connecting beam 200 to the column 100, the connecting beam 200 can be elevated, and thus the support assembly 300 connected to the connecting beam 200 can be elevated, thereby reducing the risk of the photovoltaic panel assembly 500 on the support assembly 300 being in contact with the roof. By movably connecting both ends of the support assembly 300 to at least two oppositely arranged connecting beams 200 so as to be able to slide in the direction of the connecting beams 200, the photovoltaic panel assembly 500 can be driven to slide by sliding the support assembly 300, thereby reserving an escape space to expose the roof, thereby facilitating user maintenance and cleaning of the roof.

[0050] Specifically, multiple photovoltaic arrays can be formed along the length of the connecting beam 200, each array being provided with a support assembly 300. The support assemblies 300 in all arrays can be connected to the connecting beam 200 by a sliding connection; or the support assembly 300 in at least one of two arrays can be slidably connected to the connecting beam 200 to slide along the length of the connecting beam 200, thereby facilitating the support assembly 300 slidably connected to the connecting beam 200 to drive the photovoltaic panel assembly 500 to translate, so that the photovoltaic panel assemblies 500 in different arrays can be folded into the same array, thereby exposing the roof for easy maintenance and cleaning of the roof. The support assembly 300 can include a plurality of support rods or ropes arranged at an angle to the connecting beam 200, or the support assembly 300 can further include connectors connected to both ends of the support rods or ropes to movably connect to the connecting beam 200 via the connectors.

[0051] The technical solution of the present application connects at least two oppositely disposed connecting beams 200 to the column 100, thereby elevating the support assembly 300 and the photovoltaic panel assembly 500 mounted thereon, thereby avoiding the risk of the photovoltaic panel assembly 500 adhering to the roof. By movably connecting both ends of the support assembly 300 to at least two oppositely disposed connecting beams 200, so that the support assembly 300 can be flipped relative to the connecting beams 200 or slid in the length direction of the connecting beams 200, a clearance space is reserved when the support assembly 300 flips relative to the connecting beams 200 or slides in the length direction of the connecting beams 200, thereby exposing the roof and facilitating maintenance or cleaning of the roof.

[0052] In one embodiment of this application, please refer to Figure 7 As shown, at least two mounting portions 210 are provided on the connecting beam 200, at least two mounting portions 210 are arranged along the height direction of the connecting beam 200, and at least two mounting portions 210 extend along the length direction of the connecting beam 200; at least two groups of support components 300 are respectively slidably provided on the at least two mounting portions 210 and are arranged at intervals.

[0053] By arranging at least two mounting portions 210 along the height direction of the connecting beam 200, and at least two mounting portions 210 extending along the length direction of the connecting beam 200; at least two support components 300 are respectively slidably arranged on at least two mounting portions 210 and spaced apart, at least two support components 300 can slide relative to the mounting portions 210 in the length direction of the connecting beam 200, and when any one of the at least two support components 300 slides, there is a certain distance between it and the other one, thereby reducing the risk of interference with other photovoltaic panel components 500 when any support component 300 drives the photovoltaic panel component 500 to slide. In addition, a plurality of photovoltaic arrays can be divided in the length extension direction of the connecting beam 200, and each array is provided with a support assembly 300. By sliding at least two groups of support assemblies 300 on at least two mounting portions 210 arranged along the height direction of the connecting beam 200, if any one of the at least two support assemblies 300 slides, it can drive the photovoltaic panel assembly 500 in the photovoltaic array installed thereon to move horizontally, so that the photovoltaic panel assembly 500 in the photovoltaic array and the photovoltaic panel assembly 500 in at least another photovoltaic array overlap in projection on the roof, so as to expose part of the roof, thereby facilitating cleaning or repair of the exposed roof.

[0054] Specifically, the mounting portion 210 may be a slide rail groove, and the support assembly 300 may include a slider that can be inserted into the slide rail groove and can slide in the slide rail groove; or, the mounting portion 210 may be a sliding bar, and the support assembly 300 may include a slide rail groove for the sliding bar to be inserted, etc.

[0055] In one embodiment of this application, please refer to Figure 7 As shown, the mounting portion 210 is a guide rail groove, and the support assembly 300 includes a sliding member 310 and a support body 320. The sliding member 310 is slidably arranged in the guide rail groove, and the guide rail groove has an avoidance opening 211; the support body 320 is arranged at an angle to the connecting beam 200 and is connected to the sliding member 310, and the support body 320 is provided with an avoidance opening 211.

[0056] By configuring the mounting portion 210 as a guide rail groove, and the sliding member 310 of the support assembly 300 being slidably disposed within the guide rail groove, the support assembly 300 can slide relative to the mounting portion 210 and be constrained in at least one direction by the mounting portion 210. By configuring the support body 320 at an angle to the connecting beam 200 and connecting it to the sliding member 310, the support body 320 can effectively support the photovoltaic panel assembly 500. Furthermore, by providing the support body 320 with a relief opening 211 of the guide rail groove, the groove wall of the guide rail groove can be prevented from obstructing the connection between the support body 320 and the sliding member 310, ensuring that there is sufficient relief space for the sliding member 310 to effectively connect with the support body 320.

[0057] Specifically, the support body 320 can be a support rod, a support bar, or a rope, etc., as long as it can support the photovoltaic panel assembly 500.

[0058] In one embodiment of the present application, Figure 7 As shown, a side of the guide rail groove for the support body 320 to pass through has a limiting plate 212 for limiting the sliding member 310 ; an avoidance opening 211 is formed on the limiting plate 212 .

[0059] By forming a limit plate 212 on one side of the guide rail groove through which the support body 320 passes, the limit plate 212 is used to limit the position of the sliding member 310. This reduces the risk of the sliding member 310 being pulled out of the guide rail groove by the support body 320, thereby improving the stability of the connection between the support assembly 300 and the connecting beam 200. By forming the avoidance opening 211 on the limit plate 212, the number of limit plates 212 can be reduced, thereby simplifying the installation process.

[0060] In one embodiment of the present application, a limiting plate 212 is provided on one side of the guide rail groove for the support body 320 to pass through, so as to limit the sliding member 310. Two limiting plates 212 are relatively arranged in the extension direction perpendicular to the support body 320, and an avoidance opening 211 is formed between the two limiting plates 212.

[0061] By forming a limit plate 212 on one side of the guide rail slot through which the support body 320 passes, and by limiting the position of the slider 310, the risk of the slider 310 being pulled out of the guide rail slot by the support body 320 is reduced, thereby improving the stability of the connection between the support assembly 300 and the connecting beam 200. By providing two limit plates 212 arranged opposite each other in the direction perpendicular to the extension of the support body 320, and forming an escape opening 211 between the two limit plates 212, the structure of the limit plates 212 is further simplified.

[0062] Specifically, when the limiting plate 212 is provided in the guide rail groove, it can be integrally formed with the groove wall of the guide rail groove, or it can be connected by means of plug-in, snap-on or screw connection.

[0063] In one embodiment of the present application, based on the solution that a limiting plate 212 is provided on one side of the guide rail groove for the support body 320 to pass through, the guide wheel 330 can also abut against the limiting plate 212 .

[0064] In one embodiment of this application, please refer to Figure 8 and Figure 9 , the supporting body 320 is a rope.

[0065] By configuring the support body 320 as a rope, the weight of the support assembly 300 can be reduced, thereby reducing the weight of the entire photovoltaic support.

[0066] When the support body 320 is a rope, its two ends can be connected to the sliding member 310 by binding, or by providing holes in the sliding member 310 to which the rope is connected at both ends, through which the rope is passed, and one end of the rope passing through the hole can be connected to a limiting portion to reduce the risk of the rope falling out of the hole. Specifically, the limiting portion can be a limiting ring or a limiting block.

[0067] Based on the solution that the support body 320 is a rope, in one embodiment of the present application, the support assembly 300 also includes a tensioner 600, the tensioner 600 includes a connecting part 610 and a tensioning part 620, the connecting part 610 is installed on the sliding member 310, the tensioning part 620 is transmission-connected to the connecting part 610, and the end of the rope is connected to the tensioning part 620, and the tensioning part 620 is used to tension the rope.

[0068] It should be noted that the tensioner 600 is common knowledge to those skilled in the art. For example, the tensioner 600 may be a nut and screw assembly. When the connecting portion 610 is a nut, the nut can be rotatably mounted on the sliding member 310. When the nut is rotatably mounted on the sliding member 310, the axis of the nut coincides with the longitudinal extension direction of the rope. The tensioning portion 620 is a screw, the axis of the screw coincides with the longitudinal extension direction of the rope, and one end of the screw is connected to the end of the rope, while the other end of the screw is threadedly connected to the nut. When the nut rotates, it drives the screw axially to achieve the tensioning effect on the rope. Alternatively, the tensioner 600 may further include a motor and a rack and pinion assembly that is transmission-connected to the drive motor 410, wherein the motor is fixedly mounted on the sliding member 310, and the motor has a rotatable transmission shaft, on which a gear is sleeved, and the gear and the motor may serve together as the above-mentioned connecting part 610, and the rack is the above-mentioned tensioning part 620, the gear is meshed with the rack, and the end of the rope is connected to the rack, and when the motor rotates, it can drive the gear to rotate, and then the gear rotates to drive the rack to move in its extension direction, thereby achieving a tensioning effect on the rope.

[0069] By setting up the tensioner 600, the user can adjust the tightness of the rope according to actual needs, avoiding the risk that the rope becomes loose after being used for a long time and is difficult to stably support the photovoltaic panel assembly 500; in addition, it can also avoid the risk of excessive rope tension causing the rope's service life to be reduced and easy to break.

[0070] In one embodiment of the present application, Figure 9 As shown, the support assembly 300 further includes a guide wheel 330 , which is rotatably connected to the sliding member 310 and abuts against the groove wall of the guide rail groove.

[0071] Specifically, the guide rail groove has at least two groove walls, and the guide wheel 330 can abut against any groove wall of the guide rail groove. When the guide wheel 330 is rotatably connected to the sliding member 310, it can be directly connected to the outside of the sliding member 310, or it can also be partially embedded in the sliding member 310.

[0072] By rotatably connecting the guide wheel 330 to the sliding member 310 and abutting against the wall of the guide rail groove, the guide wheel 330 can rotate relative to the sliding member 310 and roll along the wall of the guide rail groove, thereby achieving the effect of the guide wheel 330 driving the sliding member 310 to slide along the guide rail groove. This arrangement can reduce the friction between the sliding member 310 and the wall of the guide rail groove, thereby making it easier to drive the sliding member 310 to slide within the guide rail groove.

[0073] In one embodiment of the present application, a portion of the guide wheel 330 is embedded in the sliding member 310 , and another portion extends out of the sliding member 310 . The portion of the guide wheel 330 extending out of the sliding member 310 abuts against the wall of the guide rail groove.

[0074] By embedding a portion of the guide wheel 330 into the sliding member 310 and extending the other portion out of the sliding member 310, on the one hand, the space occupied by the guide wheel 330 and the sliding member 310 as a whole can be reduced, and on the other hand, it is convenient to achieve the abutment between the guide wheel 330 and the groove wall of the guide rail groove, so that the friction between the sliding member 310 and the guide rail groove is reduced by the guide wheel 330 rolling on the groove wall of the guide rail groove.

[0075] In one embodiment of the present application, Figure 9 As shown, the support assembly 300 further includes a pressing block 340 , which is connected to the support body 320 .

[0076] By connecting the pressing block 340 to the supporting body 320 , the photovoltaic panel assembly 500 can be overlapped on the pressing block 340 , thereby improving the stability and strength of supporting the photovoltaic panel assembly 500 .

[0077] Specifically, when the pressing block 340 is connected to the support body 320, the pressing block 340 may have a through-hole for the support body 320 to pass through. Thus, when the support body 320 passes through the through-hole of the pressing block 340, the pressing block 340 is sleeved onto the outside of the support body 320. Alternatively, the pressing block 340 may include two separate sub-blocks, each of which has a clamping groove for clamping the support body 320. The clamping grooves of the two sub-blocks are arranged opposite each other, and opposite sides of the support body 320 are respectively positioned within the clamping grooves of the two sub-blocks and clamped by the two sub-blocks on their opposite sides, thereby achieving the effect of connecting the pressing block 340 to the support body 320. The two sub-blocks can be connected by bolts or screws, etc., and the support body 320 is clamped between the two sub-blocks.

[0078] In one embodiment of the present application, the pressing block 340 is an elastic buffer block.

[0079] By configuring the pressing block 340 as an elastic buffer block, the pressing block 340 can buffer the force generated by the vibration of the photovoltaic panel assembly 500 and transmitted to other photovoltaic panel assemblies 500.

[0080] Specifically, the elastic buffer block can be made of rubber or silicone material, etc., as long as it can have good supporting and buffering effects.

[0081] In one embodiment of this application, please refer to Figure 10 and Figure 11 The photovoltaic support further includes a driving assembly 400 , which is transmission-connected to the supporting assembly 300 and drives the supporting assembly 300 to slide in the length direction of the connecting beam 200 .

[0082] By providing a driving assembly 400 that is transmission-connected to the supporting assembly 300 to drive the supporting assembly 300 to slide in the length direction of the connecting beam 200, the need for manual driving of the supporting assembly 300 to slide can be reduced, saving labor costs.

[0083] In one embodiment of the present application, Figure 11 As shown, the photovoltaic bracket also includes a drive assembly 400, which includes a drive motor 410, a screw 420 and a nut; the screw 420 is transmission-connected to the drive motor 410, and the extension direction of the screw 420 is consistent with the extension direction of the connecting beam 200; the nut is installed on the support assembly 300, and the nut is threadedly connected to the screw 420.

[0084] By connecting the screw rod 420 to the drive motor 410, the rotation of the drive motor 410 can drive the screw rod 420 to rotate. By installing a nut on the support assembly 300 and threadedly connected to the screw rod 420, the screw rod 420 rotates under the drive of the drive motor 410, which can cause the nut to move along the extension direction of the screw rod 420, that is, along the extension direction of the connecting beam 200, thereby achieving the effect of the nut driving the support assembly 300 to slide along the extension direction of the connecting beam 200.

[0085] Specifically, the nut can be embedded in the support assembly 300, and the support assembly 300 has a groove for the screw 420 to pass through, so that the support assembly 300 can slide without being interfered with by the screw 420. Alternatively, the nut can be provided on the side wall of the support assembly 300, that is, the nut is provided outside the support assembly 300, and when the screw 420 is connected to the nut, the screw 420 is also located outside the support assembly 300. As long as the support assembly 300 can slide in the extension direction of the connecting beam 200 without interfering with the screw 420, it will be sufficient.

[0086] Of course, in other embodiments, the screw 420 and nut in the drive assembly 400 can also be replaced by a gear rack assembly. For example, the gear is in driving connection with the drive motor 410 in the drive assembly 400, the gear meshes with the rack, and the rack is fixedly connected to the support assembly 300, with the rack extending in the same direction as the connecting beam 200. In this arrangement, when the drive motor 410 drives the gear to rotate, the gear can further drive the rack to move along the length of the rack, that is, along the extending direction of the connecting beam 200, thereby achieving the effect of the rack driving the support assembly 300 to slide along the extending direction of the connecting beam 200.

[0087] Alternatively, in other embodiments, the drive assembly 400 may include a linear motor and a transmission rod, the extension directions of the transmission shaft and the transmission rod of the linear motor are consistent with the extension direction of the connecting beam 200, and the transmission rod is fixedly connected to the support assembly 300, then the linear motor can directly drive the support assembly 300 to slide along the extension direction of the connecting beam 200 through the transmission rod.

[0088] This application also provides a photovoltaic system comprising a photovoltaic panel assembly 500 and a photovoltaic support. The specific structure of the photovoltaic support is similar to the above-described embodiments. Since this photovoltaic system utilizes all the technical solutions of all the above-described embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-described embodiments, which will not be described in detail here. The photovoltaic panel assembly 500 is mounted on the support assembly 300.

[0089] The above description is merely an exemplary embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the contents of the present application specification and drawings under the technical concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
