Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a portable foldable photovoltaic bracket. Background Technology

[0002] With the continuous development of photovoltaic power generation technology, photovoltaic technology can be seen everywhere, from large-scale centralized photovoltaic power plants to distributed rooftop photovoltaics and even off-grid power supply in remote areas. This diversified application demand places higher requirements on the portability, ease of installation, and flexibility of photovoltaic equipment.

[0003] Traditional photovoltaic (PV) mounting systems are mostly fixed structures. These systems are firmly anchored to the ground using concrete foundations or ground anchors to ensure stable support of PV modules under various weather conditions, thus guaranteeing power generation efficiency. However, this fixed structure is time-consuming to install and inconvenient to dismantle, failing to meet the emergency power supply needs of frequent relocation or temporary installations. Furthermore, because the optimal tilt angle for PV power generation varies in different regions, fixed structures cannot flexibly adjust the module tilt angle, resulting in low power generation efficiency.

[0004] Therefore, there are still shortcomings and deficiencies in the existing technology, and how to provide a portable foldable photovoltaic bracket is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a portable foldable photovoltaic bracket, which solves the technical problems that existing photovoltaic brackets are mostly fixed structures, making installation and carrying inconvenient, and unable to flexibly adjust the tilt angle of the components.

[0006] To achieve the above objectives, this utility model provides a portable foldable photovoltaic bracket, comprising:

[0007] Two ground beams;

[0008] Two inclined beams are respectively disposed on the two ground beams. One end of each inclined beam is hinged to the ground beam. A viscous damper is provided between the inclined beam and the ground beam. Both ends of the viscous damper are respectively hinged to the inclined beam and the ground beam. The end of the viscous damper connected to the ground beam can slide along the ground beam and can be relatively fixed. Limiting grooves are provided at both ends of the inclined beam along its extension direction.

[0009] The first support member and the second support member are arranged in an X-shape. The two ends of the first support member pass through two of the limiting grooves on the two inclined beams, and the second support member passes through the remaining two limiting grooves on the two inclined beams.

[0012] Preferably, a second hinge seat is fixedly provided on the bottom surface of the inclined beam, and the other end of the viscous damper is hinged to the second hinge seat. The first hinge seat and the second hinge seat have the same structure.

[0013] Preferably, a third hinge seat is fixedly provided at the top of one end of the ground beam, and the end of the inclined beam is hinged to the third hinge seat by a second bolt.

[0014] Preferably, the device further includes a connector for fastening the first support member and the second support member to the inclined beam. The connector is L-shaped and has a through hole on one side. The connector is sleeved on the first support member and the second support member through the through hole and is fixedly connected to the inclined beam.

[0015] Preferably, the first support member and the second support member are threadedly connected with locking nuts, and the locking nuts press the connecting member against the inclined beam.

[0019] Compared to the aforementioned background technology, the portable foldable photovoltaic bracket provided by this utility model can be quickly folded and unfolded by adjusting the angle between the viscous damper and the ground beam, and adjusting the angle between the first support member and the second support member and the inclined beam. This facilitates transportation and installation, and is conducive to the flexible deployment of photovoltaic power generation systems.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This invention provides a portable foldable photovoltaic bracket that can be quickly folded and unfolded, making it easy to transport and carry, and meeting the needs for flexible deployment of photovoltaic power generation systems in different scenarios.

[0033] Please refer to this as well. Figures 1 to 8 The portable foldable photovoltaic bracket provided by this utility model includes:

[0034] Two ground beams 1;

[0035] Two inclined beams 2 are respectively set on two ground beams 1. One end of the inclined beam 2 is hinged to the ground beam 1. A viscous damper 3 is provided between the inclined beam 2 and the ground beam 1. The two ends of the viscous damper 3 are respectively hinged to the inclined beam 2 and the ground beam 1. The end of the viscous damper 3 connected to the ground beam 1 can slide along the ground beam 1 and can be relatively fixed. Limiting grooves 201 are provided at both ends of the inclined beam 2 along its extension direction.

[0036] The first support member 4 and the second support member 5 are arranged in an X-shape. The two ends of the first support member 4 pass through two of the limiting grooves 201 on the two inclined beams 2 respectively, and the second support member 5 passes through the remaining two limiting grooves 201 on the two inclined beams 2 respectively.

[0037] Among them, the first support member 4 / the second support member 5 is provided with a limiting ring 501 in the middle, and the second support member 5 / the first support member 4 passes through the limiting ring 501.

[0038] Specifically, the ground beam 1 and the inclined beam 2 are tubular structures with rectangular cross-sections. The first support member 4 and the second support member 5 are generally cylindrical rod-shaped structures. The first support member 4 and the second support member 5 are connected by a limiting ring 501. The viscous damper 3 is a velocity-dependent energy-dissipating damper that uses a piston moving in a fluid to generate friction with the fluid, causing a change in the fluid's flow pattern and converting mechanical energy into heat energy for dissipation. By setting the viscous damper 3, damage to the photovoltaic support caused by wind vibration is reduced.

[0039] Figure 1 The image shown is a schematic diagram of the portable foldable photovoltaic bracket when fully extended. Figure 5The diagram shows a portable foldable photovoltaic (PV) bracket after folding. When unfolding the portable foldable PV bracket from its folded state, firstly, the end of the viscous damper 3 connected to the ground beam 1 slides along the ground beam 1. As the tilt angle of the viscous damper 3 changes, the angle between the inclined beam 2 and the ground beam 1 changes, raising the inclined beam 2 to the set tilt angle. Secondly, one end of the viscous damper 3 is relatively fixed to the ground beam 1. Then, by adjusting the angle between the first support member 4 and the second support member 5, the first support member 4 and the second support member 5 slide within the limiting groove 201 on the inclined beam 2, adjusting the distance between the two inclined beams 2 to the set distance, thus enabling the unfolding of the portable foldable PV bracket. It should be understood that the portable foldable PV bracket can be folded from its unfolded state using the corresponding operation described above.

[0040] This configuration allows for the rapid folding and unfolding of the photovoltaic bracket by adjusting the angle between the viscous damper 3 and the ground beam 1, and between the first support member 4 and the second support member 5 and the inclined beam 2. This facilitates transportation and installation, enables flexible deployment of the photovoltaic power generation system, and effectively solves the problem that fixed-structure photovoltaic brackets cannot adjust the tilt angle of the components. It adapts to the optimal tilt angle for photovoltaic power generation in different regions, ensuring maximum power generation efficiency.

[0041] In some embodiments, please refer to the following: Figures 1 to 2 , Figures 5 to 8 The ground beam 1 is provided with a groove 101 along its extension direction. A first hinge seat 103 is detachably fixed at the groove 101 by a first bolt 102. One end of the viscous damper 3 is hinged to the first hinge seat 103.

[0042] Specifically, the first hinge seat 103 has a U-shaped structure. The first bolt 102 can pass through the bottom of the first hinge seat 103 and the slide groove 101 and be locked with a nut, thereby fixing the first hinge seat 103 to the ground beam 1. The end of the viscous damper 3 can be hinged to the first hinge seat 103 by bolts or hinge shafts.

[0043] When the photovoltaic support is folded or unfolded, the first bolt 102 is first removed. At this time, the first hinge seat 103 can slide along the slide groove 101, allowing the first hinge seat 103 to slide on the ground beam 1. The first hinge seat 103 drives the viscous damper 3 to move. As the tilt angle of the viscous damper 3 changes, the tilt angle of the inclined beam 2 is adjusted. When the angle of the inclined beam 2 is adjusted to the set angle, the first hinge seat 103 is fixed to the ground beam 1 again by the first bolt 102 to ensure structural stability.

[0044] With this configuration, the first hinge seat 103 is fixed by the first bolt 102, which facilitates disassembly and installation, thereby improving the efficiency of folding or unfolding the photovoltaic bracket.

[0045] In some embodiments, please refer to the following: Figure 1 , Figures 5 to 8 The bottom surface of the inclined beam 2 is fixedly provided with a second hinge seat 202, and the other end of the viscous damper 3 is hinged to the second hinge seat 202. The first hinge seat 103 and the second hinge seat 202 have the same structure.

[0046] The second hinge seat 202 can be fixed to the inclined beam 2 by welding or bolting, and the other end of the viscous damper 3 can be hinged to the second hinge seat 202 by bolts or hinge shafts.

[0047] In some embodiments, please refer to the following: Figure 1 , Figure 3 , Figures 5 to 8 A third hinge seat 104 is fixedly provided at the top of one end of the ground beam 1, and the end of the inclined beam 2 is hinged to the third hinge seat 104 by a second bolt 105.

[0048] The third hinge seat 104 is roughly U-shaped. The third hinge seat 104 can be fixed to the ground beam 1 by welding. The third hinge seat 104 has mounting holes on both sides. The second bolt 105 passes through the mounting holes. The inclined beam 2 is hinged to the third hinge seat 104 by the second bolt 105.

[0049] In some embodiments, please refer to the following: Figure 1 , Figure 4 , Figures 5 to 8 The portable foldable photovoltaic bracket provided by this utility model also includes a connector 6. The connector 6 is used to fasten the first support 4 and the second support 5 to the inclined beam 2. The connector 6 is L-shaped and has a through hole 601 on one side. The connector 6 is sleeved on the first support 4 and the second support 5 through the through hole 601 and is fixedly connected to the inclined beam 2.

[0050] In some embodiments, please refer to the following: Figure 1 , Figures 5 to 8 The first support member 4 and the second support member 5 are threaded with locking nuts 7, which press the connecting member 6 against the inclined beam 2.

[0051] When the photovoltaic support is folded or unfolded, the first support member 4 and the second support member 5 slide within the limiting groove 201 on the inclined beam 2, respectively, and the distance between the two inclined beams 2 is adjusted to the set distance. The connecting member 6 is sleeved on the first support member 4 and the second support member 5 through the through hole 601, so that the connecting member 6 abuts against the inclined beam 2. The locking nut 7 is threadedly connected to the first support member 4 and the second support member 5, and the locking nut 7 abuts against the connecting member 6. Thus, the inclined beam 2 is securely connected to the first support member 4 and the second support member 5 through the locking nut 7 and the connecting member 6, ensuring the stability of the photovoltaic support structure.

[0052] In some embodiments, please refer to the following: Figure 1 , Figures 5 to 8 Both ends of the first support member 4 and the second support member 5 are connected to the inclined beam 2 by two connectors 6, which are located on both sides of the inclined beam 2.

[0053] Both ends of the first support member 4 and both ends of the second support member 5 are fastened to the inclined beam 2 by two connectors 6. This arrangement further ensures the reliability of the connection and the stability of the overall structure.

[0054] In some embodiments, please refer to the following: Figure 1 , Figures 5 to 8 The portable foldable photovoltaic bracket provided by this utility model also includes two parallel crossbeams 8, which are fixedly connected to two inclined beams 2 respectively. The two crossbeams 8 are used to install photovoltaic modules 10.

[0055] Photovoltaic module 10 is the core power generation unit of the solar power generation system, commonly known as "solar panel". Its function is to convert sunlight into electrical energy to provide power for the system.

[0056] In some embodiments, please refer to the following: Figure 1 , Figures 5 to 8 The top two ends of the inclined beam 2 are fixed with snap-fit ​​parts 9, and the snap-fit ​​parts 9 are provided with snap-fit ​​grooves 901. The crossbeam 8 is snap-fitted and fixed in the two snap-fit ​​grooves 901 on the two inclined beams 2.

[0057] The snap-fit ​​component 9 is roughly U-shaped, with the aforementioned snap-fit ​​grooves 901 formed on both sides. The snap-fit ​​component 9 can be fixed to the inclined beam 2 by welding, and the crossbeam 8 is accommodated in the snap-fit ​​grooves 901 and snap-fitted with the grooves 901. To further improve the connection reliability between the crossbeam 8 and the snap-fit ​​component 9, the crossbeam 8 and the snap-fit ​​component 9 can be fastened with bolts.

[0058] The portable foldable photovoltaic bracket provided by this utility model is used as follows: When the photovoltaic bracket is unfolded from its folded state, the first bolt 102 is first removed. At this time, the first hinge seat 103 can slide along the slide groove 101, allowing the first hinge seat 103 to slide on the ground beam 1. The first hinge seat 103 drives the viscous damper 3 to move. As the tilt angle of the viscous damper 3 changes, the tilt angle of the inclined beam 2 is adjusted. When the angle of the inclined beam 2 is adjusted to the set angle, the first hinge seat 103 is fixed to the ground beam 1 again by the first bolt 102 to ensure structural stability. Next, by adjusting the angle between the first support member 4 and the second support member 5, the first support member 4 and the second support member 5 slide within the limiting groove 201 on the inclined beam 2, adjusting the distance between the two inclined beams 2 to the set distance. After adjustment, the connector 6, which is sleeved on the first support member 4 and the second support member 5 through the through hole 601, is locked and fixed with a locking nut 7. The locking nut 7 presses the connector 6 against the inclined beam 2, thereby achieving a tight connection between the inclined beam 2 and the first support member 4 and the second support member 5 through the locking nut 7 and the connector 6, ensuring the stability of the photovoltaic support structure. Then, the two crossbeams 8 are fixed to the inclined beam 2 through the snap-fit ​​9, and finally, the photovoltaic module 10 is installed on the two crossbeams 8. To improve the wind resistance and overturning resistance of the support system, sandbags or similar materials can be used as counterweights to press down the ground beam 1.

[0059] This portable, foldable photovoltaic (PV) bracket enables rapid folding and unfolding through angle adjustments between the viscous damper 3 and the ground beam 1, as well as between the first support member 4 and the second support member 5 and the inclined beam 2. This facilitates transportation and installation, and allows for flexible deployment of PV power generation systems. Furthermore, it effectively solves the problem of fixed-structure PV brackets being unable to adjust the tilt angle of the modules, adapting to the optimal tilt angle for PV power generation in different regions and ensuring maximum power generation efficiency.
