Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a modular, rapid assembly photovoltaic support device for complex mountainous terrain. Background Technology

[0002] Photovoltaic support structures are the core supporting components of photovoltaic power station systems. Their function is to fix photovoltaic modules in designated positions and ensure that the photovoltaic modules receive sunlight at the optimal tilt angle, thereby ensuring the power generation efficiency and long-term stable operation of the photovoltaic system.

[0003] To address the aforementioned issues, existing patents offer solutions. However, current photovoltaic (PV) support structures lack the ability to modularly assemble them and adjust them according to the mountainous terrain. This is because mountainous terrains typically exhibit abrupt slope changes, crisscrossing gullies, and uneven geological stratification. Existing support structures are mostly rigid structures of fixed dimensions. For areas with slopes exceeding ten degrees, additional irregularly shaped concrete foundations must be poured for leveling. This not only damages the original mountain vegetation and soil structure, leading to the risk of soil erosion, but also causes localized stress concentration problems. Consequently, the main beam of the support structure is prone to bending deformation due to uneven stress, and the tilt angle deviation of the installed modules can reach more than five degrees. This results in a reduction in the amount of solar irradiance received by the PV modules, affecting power generation efficiency.

[0004] To address this, a modular, rapid-assembly photovoltaic support device for complex mountainous terrain is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a modular, rapid-assembly photovoltaic support device for complex mountainous terrain. This device addresses the lack of a modular assembly structure in existing photovoltaic supports that can be adjusted according to the terrain. Mountainous terrain is characterized by abrupt slopes, crisscrossing gullies, and uneven geological stratification. Existing supports are mostly rigid structures of fixed dimensions. For areas with slopes exceeding ten degrees, additional irregularly shaped concrete foundations are required for leveling. This not only damages the original mountain vegetation and soil structure, leading to the risk of soil erosion, but also causes localized stress concentration. Consequently, the main beam of the support is prone to bending deformation due to uneven stress, and the tilt angle deviation of the installed components can reach more than five degrees. This results in a reduction in the amount of solar radiation received by the photovoltaic modules, affecting power generation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular rapid assembly photovoltaic support device for complex mountainous terrain, comprising a support beam, a connecting mechanism at the bottom of the support beam, a lifting mechanism threadedly connected to the bottom of the connecting mechanism, the lifting mechanism comprising a protective shell, an electric telescopic rod, an extension leg, a grounding plate, and a PLC controller, the protective shell being welded to the bottom of the connecting mechanism, the electric telescopic rod being installed on the top of the inner side of the protective shell, the extension leg being slidably connected to the bottom of the inner side of the protective shell, the telescopic end of the bottom of the electric telescopic rod being welded to the top of the extension leg, the grounding plate being welded to the bottom of the extension leg, and the PLC controller being installed on the left front side of the bottom of the support beam.

[0007] Preferably, the connecting mechanism includes four connecting blocks, connecting screw holes, connecting screws, and a fixing plate, wherein the connecting blocks are welded to the chamfer at the bottom of the support beam.

[0008] Preferably, the connecting screw hole is located on the inner side of the bottom of the connecting block, and the connecting screw is threaded into the inner side of the connecting screw hole.

[0009] Preferably, the fixing plate is welded to the bottom of the connecting screw, and the protective shell is welded to the bottom of the fixing plate.

[0010] Preferably, an installation groove is provided on the inner side of the top of the support beam, and a fixing screw is welded to the chamfer of the top of the support beam.

[0011] Preferably, a transparent dustproof plate is slidably connected to the top of the support beam, and a sliding hole is provided at the chamfer of the transparent dustproof plate. The sliding hole is slidably connected to the surface of the fixing screw, and an anti-slip pad is movably connected to the surface of the fixing screw. A fixing nut is threadedly connected to the top of the surface of the fixing screw.

[0012] Preferably, the chamfer of the ground plate is provided with a connecting hole, and limit plates are welded to both sides of the ground plate, with through holes provided on the surface of the limit plates.

[0013] Preferably, a grounding rod is movably connected to the inner side of the through hole, the top of the grounding rod extends through and to the outer side of the top of the through hole, and a limit nut is threadedly connected to the top of the grounding rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The connecting blocks in the connection mechanism of this application are pre-installed at the bottom chamfer of the support beam. With the standardized connecting screw holes and connecting screws, the connection between the support beam and the lifting mechanism does not require on-site welding. It can be fixed by simply screwing on the threads. The bracket is disassembled into a modular structure of support beam unit plus lifting unit. After the components are transported to the mountain site, they can be quickly aligned and assembled, which greatly shortens the installation time of a single bracket. It is especially suitable for the narrow working space in the mountains and reduces the dependence on the professional skills of the construction personnel. The four connecting blocks correspond to the four chamfers at the bottom of the support beam, forming a symmetrical four-point support structure. This allows the load of the support beam to be evenly transferred to the lifting mechanism, avoiding local stress concentration. At the same time, the self-locking characteristics of the threaded connection, combined with the subsequent reinforcement of the fixing nuts, can effectively resist the influence of external forces such as strong winds and vibrations in the mountains, prevent the connection parts from loosening, and ensure the structural reliability of the bracket under complex working conditions. 2. The lifting mechanism of this application can independently control the extension and retraction of the electric telescopic rods in each lifting mechanism through a PLC controller, enabling the extension legs to drive the grounding plate for fine-tuning of height. For scenarios with abrupt changes in slope or uneven terrain, the support beam can be quickly adjusted to a horizontal state through the coordinated adjustment of single or multiple lifting mechanisms, ensuring that the photovoltaic modules maintain the optimal tilt angle. This allows the support structure to adapt to steep slopes of 20 to 40 degrees and terrain with crisscrossing gullies. The electric telescopic rod driving method replaces the cumbersome procedures of manual leveling and on-site cutting of traditional support structures. Construction personnel only need to input adjustment parameters through the PLC controller. It can complete the synchronous or independent leveling of multiple sets of supports, while avoiding heavy physical leveling work on mountain sites, reducing the risk of high-altitude operations, and improving construction efficiency and safety. The protective shell effectively wraps the electric telescopic pole, which can isolate it from the erosion of mountain rainwater, mud and sand and corrosive gases, extending the service life of the drive components. The rigid connection design between the extended legs and the grounding plate, together with the connection holes at the chamfer of the grounding plate and the grounding rods of the limit plates on both sides, makes the lifting mechanism form a double fixing structure with surface contact and point anchoring with the ground, which greatly improves the pull-out resistance and overturning resistance of the support, and adapts to the extreme climate conditions in mountainous areas.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A modular, rapid-assembly photovoltaic support device for complex mountainous terrain includes a support beam 1. A connecting mechanism 2 is provided at the bottom of the support beam 1. A lifting mechanism 3 is threadedly connected to the bottom of the connecting mechanism 2. The lifting mechanism 3 includes a protective shell 31, an electric telescopic rod 32, an extension leg 33, a grounding plate 34, and a PLC controller 35. The protective shell 31 is welded to the bottom of the connecting mechanism 2. The electric telescopic rod 32 is installed on the top of the inner side of the protective shell 31. The extension leg 33 is slidably connected to the bottom of the inner side of the protective shell 31. The telescopic end of the bottom of the electric telescopic rod 32 is welded to the top of the extension leg 33. The grounding plate 34 is welded to the bottom of the extension leg 33. The PLC controller 35 is installed on the left front side of the bottom of the support beam 1.

[0019] In this embodiment: By setting the support beam 1 as the core load-bearing component of the support device, it not only serves as the direct mounting carrier for the photovoltaic modules, but also supports and limits the connection mechanism 2 and the lifting mechanism 3. The protective shell 31 can effectively isolate the internal electric telescopic rod 32 from mountain rainwater, mud, vegetation debris and corrosive gases, and prevent the drive components from rusting, jamming and other failures. The electric telescopic rod 32 is driven by electricity, and with the help of the PLC controller 35, it can control the level of the support beam 1 to ensure that the photovoltaic modules maintain the optimal tilt angle. The extension leg 33 can stably transfer the driving force of the electric telescopic rod 32 and the load of the support beam 1 to the grounding plate 34. The grounding plate 34 adopts a large-area flat plate structure, which can effectively increase the contact area with the ground, reduce the grounding pressure per unit area, prevent settlement or sinking in the soft soil of the mountain, and improve the overall anti-overturning ability of the support. The PLC controller 35 can simultaneously connect to the electric telescopic rods 32 of multiple lifting mechanisms 3, and realize the synchronous or group adjustment of multiple supports through preset programs. For areas with the same slope, the overall leveling can be completed quickly.

[0020] Specifically, such as Figure 3 As shown, the connecting mechanism 2 includes four connecting blocks 21, connecting screw holes 22, connecting screws 23 and fixing plates 24. The connecting blocks 21 are welded to the chamfer at the bottom of the support beam 1.

[0021] Specifically, such as Figure 3 As shown, the connecting screw hole 22 is opened on the inner side of the bottom of the connecting block 21, and the connecting screw 23 is threaded into the inner side of the connecting screw hole 22.

[0022] Specifically, such as Figure 3 As shown, the fixing plate 24 is welded to the bottom of the connecting screw 23, and the protective shell 31 is welded to the bottom of the fixing plate 24.

[0023] In this embodiment: by setting four connecting blocks 21 corresponding to the four chamfers at the bottom of the support beam 1 respectively, a symmetrical four-point support structure is formed, which can evenly distribute the weight of the photovoltaic module, wind load and other loads carried by the support beam 1 to the four connecting screws 23. The connecting screw holes 22 can be threadedly connected to the connecting screws 23. The connecting screws 23 can drive the fixing plate 24 to be threadedly connected to the connecting blocks 21. The fixing plate 24 can support and limit the protective shell 31, and drive the protective shell 31 to be connected to the connecting blocks 21.

[0024] Specifically, such as Figure 4 As shown, an installation groove 4 is provided on the inner side of the top of the support beam 1, and a fixing screw 5 is welded to the chamfer at the top of the support beam 1.

[0025] Specifically, such as Figure 4As shown, a transparent dustproof plate 6 is slidably connected to the top of the support beam 1. A sliding hole 7 is provided at the chamfer of the transparent dustproof plate 6. The sliding hole 7 is slidably connected to the surface of the fixing screw 5. An anti-slip pad 8 is movably connected to the surface of the fixing screw 5. A fixing nut 9 is threadedly connected to the top of the surface of the fixing screw 5.

[0026] In this embodiment: the installation groove 4 allows for the installation and positioning of photovoltaic modules; the fixing screw 5, in conjunction with the sliding hole 7, positions the transparent dustproof plate 6. The transparent dustproof plate 6 effectively prevents pollutants such as mountain dust, fallen leaves, and bird droppings from adhering to the surface of the photovoltaic modules, avoiding wear on the module's glass cover or surface dust accumulation that could reduce power generation efficiency. The sliding hole 7 allows for direct alignment with the fixing screw 5 during installation, enabling rapid positioning of the transparent dustproof plate 6 without repeated calibration, thus improving installation efficiency. The anti-slip pad 8 increases the frictional resistance between the fixing nut 9 and the transparent dustproof plate 6, effectively resisting vibration and loosening caused by mountain wind loads. The fixing nut 9, in conjunction with the fixing screw 5, forms a reliable self-locking structure after tightening. Combined with the auxiliary effect of the anti-slip pad 8, it effectively resists the influence of external forces such as mountain vibrations and wind, ensuring the long-term stable installation of the transparent dustproof plate 6.

[0027] Specifically, such as Figure 5 As shown, a connecting hole 10 is provided at the chamfer of the ground plate 34, and a limiting plate 11 is welded on both sides of the ground plate 34. A through hole 12 is provided on the surface of the limiting plate 11.

[0028] Specifically, such as Figure 5 As shown, a grounding rod 13 is movably connected to the inner side of the through hole 12. The top of the grounding rod 13 passes through and extends to the outer side of the top of the through hole 12. A limit nut 14 is threadedly connected to the top of the grounding rod 13.

[0029] In this embodiment: By setting the connecting hole 10, the grounding plate 34 can be deeply fixed to the ground with anchor bolts or precast foundation. Especially in soft soil or weathered rock layers in mountainous areas, it can enhance the pull-out resistance and overturning resistance of the grounding plate 34. By setting the limiting plate 11, the through hole 12 can be supported and limited. By setting the through hole 12, the grounding rod 13 can be supported and limited. By setting the grounding rod 13, the pointed design can penetrate deep into the ground. By interlocking with the soil or rock layer, a strong anchoring force is formed, which can effectively resist the pull-out force of the support under strong wind, blizzard or geological subsidence. By setting the limiting nut 14, after tightening, the grounding rod 13 can be fixed on the limiting plate 11, so as to prevent the grounding rod 13 from loosening or floating under the action of wind and rain vibration or soil subsidence.

[0030] Working principle: First, the operator embeds the photovoltaic module into the inner side of the mounting groove 4. Then, the operator slides the transparent dustproof plate 6 through the sliding hole 7 at its chamfered corner onto the fixing screw 5, so that the dustproof plate covers the surface of the photovoltaic module. Next, the operator puts the anti-slip pad 8 on the surface of the fixing screw 5 and tightens the fixing nut 9. The anti-slip pad 8 increases the frictional resistance between the nut and the dustproof plate, and cooperates with the thread self-locking of the nut and the screw. Then, the operator screws the four connecting screws 23 into the connecting screw holes 22 respectively. The thread engagement realizes the quick fastening of the connecting block 21 and the connecting screw 23. After that, the operator hoists the assembled bracket unit to the preset installation point on the mountain. The operator starts the adjustment program through the PLC controller 35. The PLC controller 35 simultaneously connects to the electric telescopic rods 32 of multiple brackets. According to the preset adjustment parameters based on the slope data of the site, the operator controls the extension of the electric telescopic rods 32 in the protective shell 31. The extension end of the electric telescopic rod 32 drives the extension leg 33 to slide inside the protective shell 31. 3. The driving force is transmitted to the bottom grounding plate 34, which allows the grounding plate 34 to flexibly rise and fall with the terrain. For areas with uniform slope, multiple sets of supports can be synchronously leveled through the PLC controller 35. For areas with uneven slope, they are adjusted independently in groups until the support beam 1 is kept horizontal, ensuring that the photovoltaic modules are at the optimal tilt angle to improve power generation efficiency. Finally, the grounding plate 34 increases the contact area with the ground through its large-area flat plate structure, reducing grounding pressure to avoid settlement. The workers use the connection holes 10, anchor bolts or prefabricated foundations to initially fix the grounding plate 34 to the ground. Then, the operators insert the grounding rod 13 through the through holes 12 of the limiting plates 11 on both sides of the grounding plate 34 and hammer it into the ground with the pointed design. The grounding rod 13 forms a strong anchoring force through the interlocking with the soil or rock layer. Finally, the limiting nut 14 is tightened on the top of the grounding rod 13 to fix the grounding rod 13 to the limiting plate 11 to prevent it from loosening and floating. Thus, the photovoltaic modules can operate reliably in complex mountainous environments.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
