Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a support assembly, a photovoltaic support, and a photovoltaic system. Background Technology

[0002] In current floating photovoltaic (PV) projects and monopile foundation PV support projects, cable tray supports are typically fixed to the pile foundation using clamps. However, when the north-south spacing of the PV array is large, the existing pile foundation alone is often insufficient to effectively support the cable tray. To ensure the stability and reliability of the cable tray, additional cable tray piles are usually added between the north and south arrays to provide extra support. While this approach meets structural requirements, it inevitably increases the number of pile foundations, thereby raising the overall project cost.

[0003] To minimize the number of pile foundations and thus reduce project costs, another feasible solution is to increase the span of the cable trays. By extending the span, the cable trays can span larger spaces without the need for additional support piles. However, increasing the span of the cable trays means that the trays themselves need to have greater load-bearing capacity and structural stability. This usually requires a corresponding increase in the size and specifications of the cable trays, which in turn leads to increased material usage and increased processing and installation difficulties, ultimately resulting in higher project costs.

[0004] Therefore, how to optimize costs while meeting the support requirements of cable trays is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a support assembly, photovoltaic support, and photovoltaic system that can optimize costs while meeting the cable tray support requirements.

[0006] To achieve the above objectives, this application provides a support assembly for a photovoltaic support system. The photovoltaic support system includes an inclined beam and pipe piles for supporting the inclined beam. The support assembly includes:

[0007] Crossbeam, connecting to the pipe pile;

[0008] Support components, connected to the crossarm, are spaced apart from the pipe piles and are used to support the cable tray;

[0009] The vertical rod, with its two ends connected to the crossbeam and the diagonal beam respectively, is used to abut against the support components.

[0010] In some embodiments, there are two vertical rods and two support members. The ends of the two vertical rods away from the crossbeam are connected at a preset angle and fixed to the inclined beam. The two support members are respectively located on the inner side of the connection between the two vertical rods and the crossbeam.

[0011] In some embodiments, the two vertical bars and at least part of the crossbar combine to form an isosceles triangle structure.

[0012] In some embodiments, the included angle between the two vertical rods at the ends away from the crossarm is adjustable. After the included angle is adjusted, the ends of the two vertical rods away from the crossarm are fixed to the inclined beam. The crossarm is detachably connected to the pipe pile, so that the height of the crossarm is adapted to the included angle between the ends of the two vertical rods at the ends away from the crossarm.

[0013] In some embodiments, the support assembly further includes a fastener located at the connection point of the two vertical rods at the ends away from the crossarm. After the included angle of the two vertical rods at the ends away from the crossarm is adjusted, the fastener fixes the ends of the two vertical rods away from the crossarm to the inclined beam.

[0014] In some embodiments, the support assembly further includes at least two crossbeams, which are spaced apart and connected to two vertical bars, and the at least two crossbeams are used to support the inverter.

[0015] In some embodiments, a reinforcing rib is provided at the connection between the support member and the crossbeam. The reinforcing rib is triangular and has a weight-reducing hollow section.

[0016] This application also provides a photovoltaic support structure, including a pipe pile and an inclined beam, and further including two support assemblies as described above, wherein one support assembly is connected to one end of the pipe pile and the inclined beam, and the other support assembly is connected to the other end of the pipe pile and the inclined beam.

[0017] In some embodiments, the photovoltaic support also includes a front column, a rear column, a front diagonal brace, and a rear diagonal brace. One end of the front column, the rear column, the front diagonal brace, and the rear diagonal brace is connected to the top of the pipe pile by a clamp, and the other end of the front column, the rear column, the front diagonal brace, and the rear diagonal brace are respectively connected to the inclined beam by bolts.

[0018] This application also provides a photovoltaic system, including photovoltaic modules and photovoltaic brackets for mounting the photovoltaic modules, as described above.

[0019] Compared to the aforementioned background technology, the support assembly provided in this application is used for photovoltaic support. The photovoltaic support includes an inclined beam and pipe piles for supporting the inclined beam. The support assembly includes a crossbeam, a vertical rod, and a support member. The crossbeam is connected to the pipe pile, the support member is connected to the crossbeam, and both ends of the vertical rod are connected to the crossbeam and the inclined beam, respectively. The support member and the pipe pile are spaced apart. The support member is used to support the cable tray, and the vertical rod is used to abut against the support member.

[0020] The beneficial effects of this support assembly configuration include at least the following: Compared to the traditional method of simply setting support points on pipe piles, this application sets crossbeams on the pipe piles, and supports on the crossbeams, with the supports spaced apart from the pipe piles. When the north-south spacing of the photovoltaic array is large, this effectively shortens the distance between support points between the two photovoltaic arrays. This solves the problem of traditionally requiring additional cable tray piles or increasing the cable tray span, thus saving costs. Furthermore, when the cable tray rests on the supports, the vertical rods provide support and limit the movement of the supports, thereby ensuring the stability of the supports for the cable tray.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Please see Figure 1 and Figure 2 The bracket assembly 10 provided in this application embodiment is used for photovoltaic brackets. The photovoltaic bracket includes an inclined beam 30 and a pipe pile 20 for supporting the inclined beam 30. The bracket assembly 10 includes a crossbeam 11, a vertical rod 13 and a support member 12.

[0049] Please refer to the following: Figure 3 and Figure 4 , crossbeam 11 along Figure 2 or Figure 3As shown, the horizontal extension has one end of the crossbeam 11 connected to the pipe pile 20, the support member 12 extends longitudinally and extends out of the plane where the crossbeam 11 and the vertical rod 13 are located, the support member 12 is connected to the crossbeam 11, the support member 12 and the pipe pile 20 are spaced apart, the support member 12 is used to support the cable tray 100, the two ends of the vertical rod 13 are respectively connected to the crossbeam 11 and the inclined beam 30, and the vertical rod 13 is used to abut against the support member 12.

[0050] For example, crossbeams 11 can be set on the left and right sides of the pipe pile 20, and support members 12 can be set on the crossbeams 11, which is equivalent to adding support points on the left and right sides of the pipe pile 20.

[0051] Compared to the traditional method of setting support points only on the pipe pile 20, this application sets a crossbeam 11 on the pipe pile 20, and a support member 12 on the crossbeam 11. The support member 12 is set at intervals from the pipe pile 20. When the north-south spacing of the photovoltaic array is large, it is equivalent to shortening the spacing of the support points between the two photovoltaic arrays. This can solve the problem of traditionally needing to add cable tray piles or increase the span of the cable tray by 100, thus saving costs.

[0052] In addition, when the cable tray 100 is placed on the support member 12, the vertical rod 13 can support and limit the support member 12, thereby ensuring the stability of the support member 12 in supporting the cable tray 100.

[0053] Of course, depending on actual needs, the number of vertical rods 13 and support members 12 can be set to one or two.

[0054] Please refer to the following: Figure 5 When there is only one vertical rod 13 and one support member 12, one end of the crossbeam 11 is connected to the pipe pile 20, and the other end is connected to the vertical rod 13. The support member 12 extends out of the plane containing the crossbeam 11 and the vertical rod 13, and is connected to the end of the crossbeam 11 away from the pipe pile 20. The support member 12 is spaced apart from the pipe pile 20. The two ends of the vertical rod 13 are connected to the crossbeam 11 and the inclined beam 30, respectively, and the vertical rod 13 is used to abut against the support member 12. The vertical rod 13 can be set vertically or at an acute angle to the crossbeam 11. In this embodiment, it is preferred that the vertical rod 13 is set at an acute angle to the crossbeam 11.

[0055] The following example illustrates this in detail, with two vertical rods 13 and two support members 12.

[0056] Please refer to the following: Figure 6There are two vertical rods 13 and two support members 12. The ends of the two vertical rods 13 away from the crossarm 11 are connected at a preset angle (the preset angle is generally in the range of 0-180 degrees) and fixed to the inclined beam 30. The two support members 12 are respectively located on the inner side of the connection between the two vertical rods 13 and the crossarm 11. One support member 12 abuts against one of the vertical rods 13 and is connected to the crossarm 11, and the other support member 12 abuts against the other vertical rod 13 and is connected to the crossarm 11.

[0057] Specifically, the two vertical rods 13 are angle steel, which can form a certain angle as needed. After the upper ends are connected, they become a whole and are then connected and fixed to the end of the inclined beam 30 by fasteners. The crossbeam 11 is angle steel, one end of which is fixed to the clamp 80 by bolts, and the other end and the middle part are fixed to the lower ends of the two vertical rods 13 by bolts. At least part of the structure of the two vertical rods 13 and the crossbeam 11 is combined to form an isosceles triangle structure. The two support members 12 are U-shaped steel, which are respectively set at the angle between the two vertical rods 13 and the crossbeam 11, close to the vertical rods 13, and fixed to the crossbeam 11 by bolts.

[0058] It is important to emphasize that the isosceles triangular structure decomposes the vertical loads (such as the weight of photovoltaic modules and snow pressure) and horizontal loads (such as wind pressure) borne by the inclined beam 30 into two symmetrical paths, which are then transferred to the crossarm 11 and the foundation of the pipe piles 20 through the double vertical members 13, avoiding single-point stress concentration. For example, in areas with strong winds, the rigid connection of the triangular frame can resist torsional deformation caused by wind vibration, reducing the risk of structural overturning. At the same time, the two support members 12 are located on the inner side of the angle between the vertical member 13 and the crossarm 11, forming a double triangular reinforcement unit, which significantly improves the shear resistance of the support. In offshore photovoltaic projects, this can be used to cope with wave impacts and ensure the stability of the structure under dynamic loads.

[0059] When laying cable trays 100 in a north-south direction, place the cable tray 100 on top of the support member 12 and connect and fix it to the support member 12 with self-tapping screws, such as... Figure 6As shown. When the distance between the two arrays in the north-south direction is large, to avoid excessive deflection at mid-span due to excessive span of the cable tray 100, cable tray piles are usually added between the two arrays to support the cable tray 100 and shorten the span. However, in this application, each pipe pile 20 has two support members 12 on both sides, which can directly shorten the distance between the cable tray support points and shorten the cable tray span, thus eliminating the need for additional or fewer cable tray piles, saving costs. At the same time, the reduced cable tray span can also reduce the size of the cable tray 100 to a certain extent, saving costs. The support member 12 is set at the angle between the vertical rod 13 and the crossbeam 11 and is close to the vertical rod 13. This is so that when the cable tray 100 is placed at one end of the support, the vertical rod 13 can provide support and limit the other end, thereby ensuring the stability of the support. The angle between the two vertical rods 13 can be adjusted as needed, and the position of the support member 12 will also be adjusted accordingly, thereby changing the position of each support point of the north-south cable tray to meet the needs of different spans.

[0060] Please refer to the following: Figure 7 When laying cable trays 100 in the east-west direction, the cable trays 100 are placed on top of the crossarms 11 and fixed to the crossarms 11 by self-tapping screws. Therefore, this application can be used as a support for both north-south cable trays 100 and east-west cable trays 100.

[0061] Please refer to the following: Figure 8 The included angle between the two vertical rods 13 and the ends away from the crossarm 11 is adjustable. After the included angle is adjusted, the ends of the two vertical rods 13 away from the crossarm 11 are fixed to the inclined beam 30. The crossarm 11 is detachably connected to the pipe pile 20 so that the height of the crossarm 11 is adapted to the included angle between the ends of the two vertical rods 13 and the ends away from the crossarm 11.

[0062] Specifically, the tops of the two vertical rods 13 (i.e., the ends furthest from the crossarm 11) are not rigidly fixed to the inclined beam 30, but are connected to it via an adjustable hinge or pivot mechanism. This mechanism allows the two vertical rods 13 to adjust their opening angle (angle) in the vertical plane with the inclined beam 30 as a reference, so as to adapt to the installation requirements of different cable trays 100 through angle adjustment. After the angle between the two vertical rods 13 is adjusted to the target value, their tops are permanently or semi-permanently fixed to the lower surface or side of the inclined beam 30 by welding, high-strength bolts, or clamps. At this time, the vertical rods 13 and the crossarm 11 form a stable triangular support structure, bearing the vertical load and transferring it to the pipe pile 20.

[0063] Furthermore, the crossarm 11 is connected to the top of the pipe pile 20 via detachable connectors (such as flanges, pin-type sleeves, or clamps). Multiple height adjustment holes are pre-set on the sidewall or top of the pipe pile 20, allowing the crossarm 11 to rise and fall axially along the pipe pile 20 and be fixed at the desired height using bolts, pins, or hydraulic locking devices. This design ensures that when the angle between the vertical rods 13 is increased (the two vertical rods are more spread out), the crossarm 11 needs to be raised to compensate for the increased horizontal spacing at the top of the vertical rods 13; conversely, when the angle is decreased (the two vertical rods 13 are closer together), the crossarm 11 needs to be lowered. This dynamic matching of the height of the crossarm 11 with the angle between the vertical rods 13 ensures structural geometric stability and avoids stress concentration.

[0064] Using the above setup, the height of the crossarm 11 can be adjusted within a certain range according to actual needs. The crossarm 11 can be moved upwards and connected and fixed to the support column and diagonal brace 30 to meet the height requirements of different projects for the cable tray 100.

[0065] In some embodiments, the support assembly 10 further includes a fastener located at the connection point of the two vertical rods 13 at the ends away from the crossarm 11. After the included angle of the ends of the two vertical rods 13 away from the crossarm 11 is adjusted, the fastener fixes the ends of the two vertical rods 13 away from the crossarm 11 to the inclined beam 30. Of course, the fastener can be a bolt.

[0066] In this way, once the included angle of the two vertical rods 13 is adjusted to the target value, their top ends are fixed to the lower surface or side of the inclined beam 30 by bolt connection.

[0067] Please refer to the following: Figure 9 The support assembly 10 also includes at least two crossbeams 14, which are vertically spaced and connected to two vertical rods 13. The at least two crossbeams 14 are used to support the inverter.

[0068] In other words, in addition to supporting the cable tray 100, the bracket assembly 10 can also serve as an inverter bracket, with the inverter mounted on at least two crossbeams 14, and the at least two crossbeams 14 connected to two vertical rods 13. This installation method allows the inverter to be installed as high as possible, meeting the requirements of some projects for inverter installation height and avoiding the impact of floods or waves on the inverter.

[0069] In some embodiments, in order to strengthen the connection between the support member 12 and the crossbeam 11 and increase stability, a reinforcing rib is provided at the connection between the support member 12 and the crossbeam 11. The reinforcing rib is triangular and has a weight-reducing hollow part, so as to achieve the requirements of lightweight design while ensuring strength.

[0070] This application addresses the common problem in current photovoltaic projects that require additional cable tray piles or increased cable tray spans by proposing a new cable tray support structure. This support assembly 10 can accommodate both cable tray and inverter support structures. By increasing the support points for the north-south cable tray, the cable tray span is shortened, saving costs. The included angle of the two vertical rods 13 can be adjusted as needed, thereby changing the span of each cable tray segment to meet the requirements of different projects. Simultaneously, this support assembly 10 can serve as both a north-south and east-west cable tray support, and the cable tray height can be adjusted within a certain range according to project needs. It can also function as an inverter support, offering multiple applications.

[0071] The photovoltaic support provided in this application includes a pipe pile 20 and an inclined beam 30, and also includes two support assemblies 10 as described in the above specific embodiments, wherein one support assembly 10 is connected to one end of the pipe pile 20 and the inclined beam 30, and the other support assembly 10 is connected to the other end of the pipe pile 20 and the inclined beam 30.

[0072] In some embodiments, the photovoltaic support also includes a front column 40, a rear column 50, a front diagonal brace 60, and a rear diagonal brace 70. One end of the front column 40, the rear column 50, the front diagonal brace 60, and the rear diagonal brace 70 is connected to the top of the pipe pile 20 by a clamp 80, and the other end of the front column 40, the rear column 50, the front diagonal brace 60, and the rear diagonal brace 70 is connected to the inclined beam 30 by bolts.

[0073] The photovoltaic system provided in this application includes a photovoltaic module 90 and a photovoltaic bracket as described in the above specific embodiments for mounting the photovoltaic module 90. The photovoltaic module 90 is specifically mounted on the inclined beam 30.
