Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, and in particular to a photovoltaic panel installation structure for a photovoltaic energy storage system. Background Technology

[0002] Currently, with the global energy structure transitioning towards clean energy, photovoltaic energy storage systems are widely used in industrial and commercial settings, residential rooftops, and large-scale photovoltaic power plants due to their efficient conversion and storage capabilities for solar energy. As the core power generation component of the system, the stability of the photovoltaic panel's installation structure and the ease of installation and disassembly directly affect the overall power generation efficiency, operation and maintenance costs, and service life of the system. However, the current mainstream photovoltaic panel installation technologies still have the following key issues.

[0003] Traditional photovoltaic (PV) panel installations often rely on a single bolt for fixation, directly connecting the PV panel frame to the crossbeam using one or two bolts. This connection method has two major drawbacks: First, the contact area is extremely small, relying solely on the local contact between the bolt and the hole to transfer the load. When encountering strong winds or ground vibrations, the gap between the bolt and the hole can cause the PV panel to sway laterally or vertically. Prolonged swaying not only accelerates bolt wear and loosens the threads but also causes fatigue damage at the connection point between the PV panel and the crossbeam. Second, the load distribution is uneven. A single bolt must bear the entire vertical weight of the PV panel and the lateral wind load, easily leading to bolt shear deformation or breakage. Especially in harsh environments such as typhoon seasons and high altitudes, the incidence of PV panel falls and tilting accidents caused by connection failure increases significantly. Furthermore, single-bolt fixation has weak resistance to settlement. When slight foundation settlement occurs at the installation site, the crossbeam is prone to tilting, and the rigid connection of the bolt cannot adapt to this small displacement, leading to an imbalance of forces on the PV panel, excessive stretching or compression in some areas, and ultimately damaging the internal cell structure of the PV panel.

[0004] To address these issues, we propose a photovoltaic panel installation structure for a photovoltaic energy storage system. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a photovoltaic panel installation structure for a photovoltaic energy storage system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A photovoltaic panel mounting structure for a photovoltaic energy storage system includes: a photovoltaic panel, on both sides of which a first locking plate is detachably mounted, and each first locking plate is fixedly connected with a plurality of first locking teeth; two crossbeams, each located on one side of the bottom of the photovoltaic panel, and a second locking plate detachably mounted on each crossbeam, the second locking plate having a plurality of toothed grooves; and a connecting mechanism located between the first locking plates and the second locking plates, the connecting mechanism having sides adapted to the first locking teeth and toothed grooves respectively, and the photovoltaic panel being detachably connected to the crossbeams via the connecting mechanism.

[0007] Preferably, the connecting mechanism includes a connector that can be detachably installed between the first locking plate and the second locking plate. A plurality of second locking teeth are fixedly connected to the side wall of the connector, and a plurality of third locking teeth are fixedly connected to the other side wall of the connector. The second locking teeth engage with the first locking teeth, and the third locking teeth engage with the tooth groove.

[0008] Preferably, the connector is L-shaped, with its two sides corresponding to the photovoltaic panel and the crossbeam, respectively.

[0009] Preferably, the photovoltaic panel has symmetrical first holes on both sides, and the first locking plate has a third hole through both sides.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-4 A photovoltaic panel mounting structure for a photovoltaic energy storage system, comprising: Photovoltaic panel 1, both sides of photovoltaic panel 1 are detachably installed with first locking plates 13, and each first locking plate 13 is fixedly connected with a number of first locking teeth 16; There are two crossbeams 3, which are respectively set on the bottom sides of the photovoltaic panel 1. A second locking plate 31 is detachably installed on the crossbeam 3. The second locking plate 31 has several toothed grooves 36. The connecting mechanism is located between the first locking plate 13 and the second locking plate 31. The two sides of the connecting mechanism are respectively adapted to the first locking tooth 16 and the tooth groove 36. The photovoltaic panel 1 is detachably connected to the crossbeam 3 through the connecting mechanism.

[0018] First, during the pre-assembly stage of the components, a first locking plate 13 with first locking teeth 16 is installed on both sides of the photovoltaic panel 1, and a second locking plate 31 with toothed grooves 36 is installed on the crossbeam 3. The second locking plate 31 is connected to the crossbeam 3 through the toothed grooves 36. During the connection implementation stage, the connecting mechanism acts as an intermediate transmission carrier, and its two sides are precisely matched with the first locking teeth 16 and toothed grooves 36 respectively. Through the meshing action between the tooth surfaces, the vertical load generated by the photovoltaic panel 1 is converted into a combined horizontal and vertical force, which is transmitted to the crossbeam 3. Through the friction between the tooth surfaces and the mechanical meshing resistance, the horizontal and vertical displacement of the photovoltaic panel 1 is effectively restricted, avoiding loosening caused by external forces such as strong winds. At the same time, the detachable design allows the photovoltaic panel 1 to be positioned by adjusting the position of the first and second locking plates 31 during installation, and the components can be disassembled by separating the connecting mechanism during maintenance without damaging the main structure.

[0019] Furthermore, the connecting mechanism includes a connector 2 that can be detachably installed between the first locking plate 13 and the second locking plate 31. Several second locking teeth 23 are fixedly connected to the side wall of the connector 2, and several third locking teeth 24 are fixedly connected to the other side wall of the connector 2. The second locking teeth 23 engage with the first locking teeth 16, and the third locking teeth 24 engage with the tooth groove 36.

[0020] The second locking tooth 23 on the side wall of the connector 2 forms a first set of meshing pairs with the first locking tooth 16 of the first locking plate 13, and the third locking tooth 24 on the other side wall forms a second set of meshing pairs with the tooth groove 36 of the second locking plate 31. The two sets of meshing pairs are vertically distributed and can respectively bear and transmit the vertical force of the photovoltaic panel 1 and the lateral support force of the crossbeam 3. When the photovoltaic panel 1 bears its own weight or snow load, the force is first transmitted to the first locking plate 13 through the photovoltaic panel 1, and then converted into pressure distributed along the tooth surface through the meshing surfaces of the first and second locking teeth 23, and transmitted to the connector 2. The connector 2 redirects the vertical force to the third locking tooth 24. Through the meshing action of the third locking tooth 24 and the tooth groove 36, the force is distributed to the crossbeam 3, effectively avoiding stress concentration at a single connection point. At the same time, when the meshing surface is worn, only the connector 2 needs to be disassembled for replacement.

[0021] Furthermore, the connector 2 is L-shaped, with its two sides corresponding to the photovoltaic panel 1 and the crossbeam 3, respectively.

[0022] When the photovoltaic panel 1 is subjected to a vertical load, the vertical side transmits the force to the right-angle inflection point, and then distributes it evenly to the crossbeam 3 through the horizontal side. When encountering strong winds that generate horizontal thrust, the horizontal side can transmit the lateral force to the right-angle inflection point, and then transmit it to the overall structure of the photovoltaic panel 1 through the vertical side, forming a two-way force transmission closed loop. At the same time, the large-area contact characteristics of the L-shaped structure can increase the contact area with the photovoltaic panel 1 and the crossbeam 3, reduce the stress intensity per unit area, and further improve the deformation resistance.

[0023] Furthermore, the photovoltaic panel 1 has symmetrical first holes 11 on both sides of its side walls, and the first locking plate 13 has a third hole 14 through both sides. The first hole 11 and the third hole 14 have the same inner diameter. A first bolt 4 is inserted into the first hole 11, and the first bolt 4 is internally threaded into the third hole 14. Both the first hole 11 and the third hole 14 have internal threads.

[0024] The first holes 11 on both sides of the photovoltaic panel 1 and the third holes 14 on the first locking plate 13 have the same inner diameter, which can form a precise coaxial positioning. The coaxiality of the holes ensures that the first bolt 4 can be smoothly inserted, avoiding bolt tilting or jamming due to hole diameter deviation. During the tightening stage, when the first bolt 4 is screwed into the hole and tightened, the external thread of the bolt and the internal thread of the hole form a tight engagement. The preload is generated by the friction between the thread surfaces, which tightly presses the first locking plate 13 onto the side of the photovoltaic panel 1.

[0025] Furthermore, the photovoltaic panel 1 has symmetrical second holes 12 on both sides, the first locking plate 13 has a fourth hole 15 through both sides, and the connector 2 has a fifth hole 21 through one side. The second holes 12, the fourth holes 15 and the fifth hole 21 have the same inner diameter. A second bolt 41 is inserted into the corresponding second holes 12 and the fourth holes 15, and the second bolt 41 is internally threaded into the fifth hole 21. The second holes 12, the fourth holes 15 and the fifth hole 21 all have internal threads.

[0026] During the hole alignment stage, the second hole 12 of the photovoltaic panel 1, the fourth hole 15 of the first locking plate 13, and the fifth hole 21 of the connector 2 have the same inner diameter, which can form a coaxial through installation channel. The coaxial design of the holes of multiple components ensures that the second bolt 41 can be inserted into the three components at one time, avoiding loosening of the connection due to hole misalignment. When the second bolt 41 is tightened, the preload generated will act on the contact surface of the three components at the same time: tightly pressing the connector 2 against the side of the first locking plate 13, and tightly pressing the first locking plate 13 against the side of the photovoltaic panel 1. At the same time, when a component is subjected to external force, other components can share the force through the connection of the bolts, avoiding stress concentration in a single component.

[0027] Furthermore, the crossbeam 3 is provided with several seventh holes 32, and the second locking plate 31 is provided with ninth holes 34 on both sides. The seventh holes 32 and the ninth holes 34 have the same inner diameter. Correspondingly, the seventh holes 32 and the ninth holes 34 are provided with third bolts 42, and each third bolt 42 is threaded with a nut at the other end.

[0028] The seventh holes 32 on the crossbeam 3 are evenly distributed. The ninth hole 34 of the second locking plate 31 can be aligned with the seventh holes 32 at different positions according to the size requirements of the photovoltaic panel 1. The lateral position adjustment of the second locking plate 31 can be achieved by flexibly selecting the hole position to meet the installation requirements of photovoltaic systems of different specifications. After the third bolt 42 is inserted into the aligned seventh hole 32 and ninth hole 34, the preload generated during the tightening process will press the second locking plate 31 tightly against the surface of the crossbeam 3, restricting the vertical displacement between the two.

[0029] Furthermore, the crossbeam 3 has several eighth holes 33 through it, the second locking plate 31 has tenth holes 35 through it on both sides, and the connector 2 has a sixth hole 22 through it in the middle of the other side. The sixth hole 22, the eighth hole 33 and the tenth hole 35 have the same inner diameter, and a fourth bolt 43 is installed through it in the corresponding sixth hole 22, the eighth hole 33 and the tenth hole 35. A nut is threaded onto the other end of each fourth bolt 43.

[0030] The sixth hole 22 of connector 2, the eighth hole 33 of crossbeam 3, and the tenth hole 35 of second locking plate 31 have the same inner diameter, forming a coaxial through installation channel. The precise alignment of the holes of multiple components ensures that the fourth bolt 43 can be inserted into the three components at one time to fix the photovoltaic panel 1 on the crossbeam 3. When the fourth bolt 43 is tightened, its preload will tightly press the connector 2, the second locking plate 31, and the crossbeam 3 together. The load of photovoltaic panel 1 transmitted by connector 2 can be directly transmitted to the crossbeam 3 through the fourth bolt 43. At the same time, the second locking plate 31, as an intermediate support component, can further distribute the load to a larger area of ​​the crossbeam 3 to avoid local stress concentration.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
