Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to mobile photovoltaic foundations and photovoltaic power generation systems. Background Technology

[0002] Solar energy, as a clean, renewable, and widely distributed green energy source, has significant environmental benefits and economic value. Photovoltaic power generation technology, as a major form of solar energy utilization, has been widely applied due to its advantages such as high modularity, flexible installation, and low maintenance costs.

[0003] In photovoltaic (PV) power generation systems, the PV foundation is a crucial structural component connecting the upper PV support structure to the lower ground surface. Its core function is to safely and stably support the PV array and resist external forces such as wind loads and snow loads. Traditional PV foundations mainly adopt cast-in-place concrete foundations or permanent driven / screw-in steel pile foundations.

[0004] However, traditional photovoltaic foundations have long construction cycles and consume a lot of materials. Once built, they are difficult to dismantle or relocate, which limits their application in scenarios where land resources are limited, project cycles are short, or layout needs to be dynamically adjusted. Summary of the Invention

[0005] In view of this, the present invention provides a mobile photovoltaic foundation to solve the problem that traditional photovoltaic foundations are difficult to dismantle or relocate after construction.

[0006] In a first aspect, the mobile photovoltaic foundation provided by the present invention includes a prefabricated support module and a fixing module. The prefabricated support module is provided with an installation interface for installing photovoltaic brackets; the fixing module is connected to the prefabricated support module through a detachable structure for installing the prefabricated support module on the site surface.

[0007] Beneficial effects: The fixed modules are connected to the prefabricated support modules via a detachable structure, giving the photovoltaic foundation a detachable capability. This allows for rapid disassembly of the modules when relocation or scale adjustment is needed, supports recycling, and eliminates the need for destructive demolition or costly reconstruction. This reduces construction waste generated during demolition, decreases on-site concrete usage, and lowers carbon emissions. Furthermore, since the prefabricated support modules are mass-produced in the factory, they do not require curing time like cast-in-place concrete upon arrival at the site and can be installed directly, shortening the on-site construction cycle and reducing labor and time costs.

[0008] In one optional embodiment, the prefabricated support module is a truss structure, including multiple members connected by several connection nodes; the installation interface is located at the top of the prefabricated support module; the prefabricated support module further includes a first connecting part located at the bottom of the prefabricated support module; the fixing module is a support pile, and the support pile is provided with a second connecting part; wherein, in the first connecting part and the second connecting part, one of them is provided with an internal thread structure, and the other of them is provided with an external thread structure adapted to the internal thread structure, and the external thread structure is threadedly connected to the internal thread structure.

[0009] Beneficial effects: By adopting a truss structure for the prefabricated support modules, which consist of multiple rods and connecting nodes, the prefabricated support modules are lightweight and high-strength. Furthermore, they can be standardized and mass-produced in factories. The connection with the fixed module is simply a matter of tightening the threads, resulting in rapid construction. When the photovoltaic array needs to be moved or adjusted, the prefabricated support module can be separated from the fixed module (support pile) simply by unscrewing the internal / external threads of the threaded connection, without destructive dismantling, saving time and labor costs and shortening the power plant construction cycle. Simultaneously, the threaded connection itself has adjustable stroke; by rotating the prefabricated support module or fixed module, its height can be finely adjusted to ensure that the elevation of the installed photovoltaic panels meets the requirements.

[0010] In one optional embodiment, the prefabricated support module is an assembled plate structure, comprising a prefabricated concrete horizontal slab and at least two prefabricated concrete vertical slabs, the at least two prefabricated concrete vertical slabs being arranged at intervals above the site, adjacent two prefabricated concrete vertical slabs being connected by a prefabricated concrete horizontal slab, and at least one of the prefabricated concrete horizontal slabs and at least two prefabricated concrete vertical slabs having an installation hole; the fixing module is a connecting pile, the bottom of the connecting pile being embedded in the site, and the top of the connecting pile being used for installation in the installation hole.

[0011] Beneficial effects: Precast concrete vertical and horizontal slabs are standardized and manufactured in the factory. On-site, the slabs are simply arranged at intervals and connected by horizontal slabs to form support modules, eliminating the need for complex on-site procedures required for traditional cast-in-place concrete, thus significantly shortening the construction cycle. Simultaneously, the previously immovable concrete foundation can be disassembled and relocated entirely. During relocation, it can be disassembled, hoisted, and transported to the new site for reassembly, saving the enormous costs of concrete waste disposal and new material costs associated with abandoning traditional foundations. Furthermore, the connecting piles are embedded in the ground (e.g., in a concrete pit or fixed with anchor bolts), providing deep anchoring force. The mechanical engagement between the top and the mounting holes enhances the overall structural rigidity, effectively resisting external forces such as wind and snow loads. When relocation is required, only the fixing relationship between the connecting piles and the mounting holes needs to be removed to separate the precast support modules, without the need for complete destructive demolition. The modules can be transported as a whole to the new site for reuse.

[0012] In one optional embodiment, both the precast concrete vertical slab and the precast concrete horizontal slab are spliced ​​together from several slabs, and each slab has a filling chamber inside, which is used to fill concrete.

[0013] Beneficial effects: Precast concrete vertical and horizontal slabs are assembled from several independent slabs, rather than being cast as a single unit. This allows for standardized production of each slab in a factory, and on-site assembly is simply required to form a complete support module. When relocation is needed, the entire support module can be disassembled into smaller units simply by breaking down the slabs, facilitating transport to a new site for reassembly. This avoids the drawback of traditional foundations, which are too rigid to be moved. Furthermore, each slab contains an internal filling chamber for concrete. After filling with concrete, the joints between the slabs are completely filled, forming a monolithic structure similar to cast-in-place concrete. This effectively resists external forces such as wind and snow loads, ensuring long-term stability.

[0014] In one alternative embodiment, any of the precast concrete slabs has an installation slope on its side, the slope angle of which is the same as the installation angle of the photovoltaic panel.

[0015] Beneficial effects: The installation slope on the side of the precast concrete slab is adapted to the optimal installation angle of the photovoltaic panel, reducing power generation loss caused by improper angle.

[0016] In one optional embodiment, the prefabricated support module is a pile-column structure, including a support column, the top of which is provided with an installation interface; the fixing module is a fixing base, the top of which is detachably connected to the support column, and the bottom of which is provided with a threaded connection part for screwing into the site.

[0017] Beneficial effects: The support column has an installation interface at the top. The top of the fixed base connects to the support column via a detachable connection, and the bottom is screwed into the ground via a threaded connection to form an anchor. During installation, the threaded connection is pressed into the ground by rotation, avoiding traditional concrete pouring or pile driver excavation. No concrete curing or large machinery is required; the installation of the fixed base can be completed simply by rotation. During dismantling, operators only need to separate the upper support column from the fixed base and then rotate the fixed base in the opposite direction to remove it completely from the ground. The entire process eliminates the need for destructive operations such as excavation, blasting, and heavy pile extraction, solving the problems of high costs and large amounts of construction waste associated with traditional cast-in-place concrete foundations, as well as the easy bending and deformation and difficulty in reusing permanent driven steel piles during extraction. It achieves non-destructive dismantling and complete recycling of the foundation, making relocation work simple and efficient, and significantly reducing time, labor, and equipment costs.

[0018] In one optional embodiment, the bottom of the fixed base is provided with a connecting cylinder, and the inner wall of the connecting cylinder is provided with the threaded connection portion; or, the bottom of the fixed base is provided with a connecting pile, and the outer wall of the connecting pile is provided with the threaded connection portion.

[0019] Beneficial effects: The fixed base has a connecting cylinder at the bottom with a threaded connection on its inner wall. Ground fixation is achieved by screwing the matching connecting pile into the connecting cylinder. Alternatively, a connecting pile with external threads can be directly installed at the bottom of the fixed base, and the entire connecting pile is screwed into the ground by rotation. Both methods use pure rotary mechanical motion to implant the fixing module underground, avoiding the pit digging, formwork, and curing required for traditional cast-in-place concrete, or the violent driving operations required for permanent steel piles. Disassembly is simple: just reverse rotation allows the fixing module to be completely removed from the soil, making site restoration extremely simple and quick. Furthermore, no additional accessories are needed; the connecting pile is driven into the soil directly by rotation, eliminating the need for additional excavation. The screw-in installation causes minimal soil disturbance, and the ground naturally recovers after removal, reducing damage to vegetation and the ecosystem. In addition, the threaded connection allows for screwing in and out without destructive removal. When the project is terminated or the position needs to be adjusted, simply reverse rotation allows the connecting cylinder or connecting pile to be removed.

[0020] In one optional embodiment, the prefabricated support module is an integrally formed structure, including several connected connecting beams, which are spliced ​​together to form a support foundation; the fixing module is a support boss, which is provided in several forms, and the array of several support bosses is installed at the bottom of the support foundation, and the cross-sectional area of ​​the support boss gradually decreases in the direction away from the support foundation.

[0021] Beneficial effects: By molding the prefabricated support modules as a single unit, they are manufactured in the factory as complete and robust units. Upon arrival at the site, they can be directly hoisted, eliminating the tedious and time-consuming process of assembling numerous rods or plates on-site. Disassembly is similarly straightforward, requiring only the entire foundation unit to be lifted. Compared to trusses requiring individual bolt connections on-site or spliced ​​concrete slabs, this reduces on-site work and connection points, lowers quality risks due to human error, and shortens installation and disassembly time, making relocation work exceptionally efficient. Furthermore, by gradually decreasing the cross-sectional area of ​​the support boss along the direction away from the support foundation, the inclined surface of the support boss can more evenly distribute the force to the soil when subjected to downward pressure. This makes it easier to insert or place on the site surface, and stable contact can be achieved with minimal adjustments even on uneven ground. Furthermore, by installing the support protrusions in an array at the bottom of the support foundation to form multiple independent support points, the weight and wind load of the photovoltaic array can be evenly distributed, reducing local stress concentration and lowering the risk of foundation cracking. By adjusting the array density and spacing of the support protrusions, it can be flexibly adapted to uneven terrain such as slopes and soft soil without the need for additional excavation or compaction.

[0022] In one alternative implementation, several connecting beams are spliced ​​into a square, sun, or I-shaped structure.

[0023] Secondly, the present invention also provides a photovoltaic power generation system, including the mobile photovoltaic foundation provided in the preceding aspect.

[0024] Beneficial effects: Since the photovoltaic power generation system includes a mobile photovoltaic base, it has the same effect as the mobile photovoltaic base, so it will not be elaborated here. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] The following describes the embodiments of the present invention in conjunction with Figures 1 to 12 , describing the embodiments of the present invention.

[0044] According to an embodiment of the present invention, on the one hand, a mobile photovoltaic foundation is provided, as shown in Figure 1 , including a prefabricated support module 1 and a fixing module 2.

[0045] Among them, the prefabricated support module 1 is provided with an installation interface for installing a photovoltaic support; the fixing module 2 is connected to the prefabricated support module 1 through a disassembly structure for installing the prefabricated support module 1 on the site surface.

[0046] With this configuration, the fixed module 2 is connected to the prefabricated support module 1 through a disassembly structure, which enables the photovoltaic foundation to be disassembled. This allows for quick disassembly of the module when relocation or scale adjustment is required, supports recycling, eliminates the need for destructive demolition or high-cost reconstruction, reduces construction waste generated during demolition, reduces on-site concrete usage, and lowers carbon emissions.

[0047] Meanwhile, since the prefabricated support module 1 is mass-produced in the factory, it does not need to wait for curing time like cast-in-place concrete after being transported to the site, and can be installed directly, shortening the on-site construction cycle and reducing labor and time costs.

[0048] It should be noted that this application does not specify the method of disassembling and connecting the prefabricated support module 1 and the fixing module 2.

[0049] As one implementation method, such as Figure 2 and Figure 3 As shown, the prefabricated support module 1 is a truss structure.

[0050] The prefabricated support module 1 includes multiple rods 11 connected by several connection nodes; the installation interface is located at the top of the prefabricated support module 1; the prefabricated support module 1 also includes a first connecting part located at the bottom of the prefabricated support module 1; the fixing module 2 is a support pile 21, and the support pile 21 is provided with a second connecting part; wherein, in the first connecting part and the second connecting part, one of them is provided with an internal thread structure, and the other of them is provided with an external thread structure adapted to the internal thread structure, and the external thread structure is threadedly connected to the internal thread structure.

[0051] This configuration, by adopting a truss structure for the prefabricated support module 1, which consists of multiple rods 11 and connecting nodes, enables the prefabricated support module 1 to be lightweight and high-strength. It also allows for standardized and mass-produced factory prefabrication. The connection with the fixed module 2 is simply a matter of tightening the threads, resulting in fast construction speed.

[0052] When it is necessary to relocate or adjust the photovoltaic array, simply unscrew the internal / external threaded structure of the threaded connection to separate the prefabricated support module 1 from the fixed module 2 (support pile 21), without the need for destructive dismantling, saving time and labor costs and shortening the power station construction cycle.

[0053] Meanwhile, the threaded connection itself has an adjustable stroke. By rotating the prefabricated support module 1 or the fixing module 2, its height can be finely adjusted so that the elevation of the installed photovoltaic panel 3 meets the requirements.

[0054] Preferably, the connection node is a bolt ball connection node.

[0055] Similarly, the support pile 21 is selected as a helical pile.

[0056] With this configuration, by selecting a truss structure for the prefabricated support module 1 and a helical pile for the support pile 21, the foundation after installation has a good anti-slip effect.

[0057] Furthermore, the cross-section of the truss structure is a regular trapezoidal structure, with the upper length dimension being smaller than the lower length dimension.

[0058] In the above embodiments, the concrete module is filled with prestressed concrete or fiber-reinforced concrete.

[0059] In the above embodiments, the members of the truss structure are made of carbon steel, stainless steel or aluminum alloy.

[0060] As a second implementation method, such as Figures 4 to 7 As shown, the prefabricated support module 1 is an assembled plate structure.

[0061] The precast support module 1 includes a precast concrete horizontal slab 12 and at least two precast concrete vertical slabs 13. The at least two precast concrete vertical slabs 13 are arranged at intervals above the site. Adjacent precast concrete vertical slabs 13 are connected by the precast concrete horizontal slab 12. At least one of the precast concrete horizontal slab 12 and the at least two precast concrete vertical slabs 13 is provided with an installation hole. The fixing module 2 is a connecting pile 22. The bottom of the connecting pile 22 is embedded in the site, and the top of the connecting pile 22 is used for installation in the installation hole.

[0062] With this setup, the precast concrete vertical slabs 13 and horizontal slabs are produced in a standardized manner in the factory. On-site, the vertical slabs only need to be arranged at intervals and connected by the horizontal slabs to form a support module. Unlike traditional cast-in-place concrete, there is no need for complex on-site procedures, which greatly shortens the construction cycle.

[0063] At the same time, the originally immovable concrete foundation has the possibility of being dismantled and relocated as a whole. During relocation, it can be disassembled, hoisted and transported to the new site and then reassembled, saving the huge costs of concrete waste disposal and new material costs incurred due to the abandonment of traditional foundations.

[0064] In addition, the bottom of the connecting pile 22 is embedded in the ground (such as a concrete foundation pit or anchor bolt fixing) to provide deep anchoring force, and the mechanical engagement between the top and the installation hole enhances the overall structural rigidity and effectively resists external forces such as wind load and snow load.

[0065] When relocation is required, the prefabricated support module 1 can be separated simply by removing the fixing relationship between the connecting pile 22 and the mounting hole, without the need for overall destructive dismantling. The module can be transported as a whole to a new site for reuse.

[0066] In one embodiment, both the precast concrete vertical slab 13 and the precast concrete horizontal slab 12 are spliced ​​together from several slabs, and each slab has a filling chamber inside, which is used to fill concrete.

[0067] With this configuration, the precast concrete vertical slab 13 and horizontal slab are spliced ​​together from several independent slabs, rather than being cast as a whole. This allows for standardized production of each slab in the factory, and on-site assembly is only required to form a complete support module. When relocation is required, the spliced ​​slabs can be disassembled into smaller units, which are easy to transport to a new site for reassembly. This avoids the defect of traditional foundations that cannot be relocated due to their strong integrity.

[0068] Meanwhile, each slab has an internal filling chamber for filling with concrete. After the concrete is filled, the joints between the slabs are completely filled, forming an integral structure similar to cast-in-place concrete, which effectively resists external forces such as wind load and snow load, ensuring long-term stability.

[0069] In one embodiment, such as Figure 4 and Figure 5 As shown, any precast concrete slab 13 has an installation slope 131 on its side, and the slope angle of the installation slope 131 is the same as the installation angle of the photovoltaic panel 3.

[0070] With this configuration, the installation slope 131 on the side of the precast concrete slab 13 is adapted to the optimal installation angle of the photovoltaic panel 3, reducing power generation loss caused by improper angle.

[0071] In one embodiment, the precast concrete vertical slab 13 and the precast concrete horizontal slab 12 are the same plate, the only difference being whether they are arranged horizontally or vertically.

[0072] The panels, when viewed from above, present a straight or L-shaped structure.

[0073] During installation, the two precast concrete vertical slabs 13 are connected by one or two precast concrete horizontal slabs 12 to form an I-shaped or square-shaped structure.

[0074] In one embodiment, the plate has a reserved hole, and the prefabricated support module 1 also includes a short pile. During installation, the short pile is provided with an anti-slip cap 14.

[0075] In one embodiment, the base of the precast concrete vertical slab 13 is widened and placed directly on the site during installation, at which time the connecting pile 22 is embedded in the ground.

[0076] As a third implementation method, such as Figure 8 As shown, the prefabricated support module 1 is a pile-column structure, including a support column 15, with an installation interface at the top of the support column 15; the fixing module 2 is a fixing base 23, with the top of the fixing base 23 detachably connected to the support column 15, and the bottom of the fixing base 23 is provided with a threaded connection part, which is used to screw into the site.

[0077] With this configuration, the top of the support column 15 is equipped with an installation interface, and the top of the fixed base 23 is connected to the support column 15 through a detachable connection. The bottom is screwed into the ground through a threaded connection to form an anchor. During installation, the threaded connection is pressed into the ground by rotation, avoiding traditional concrete pouring or pile driver excavation. No concrete curing or large machinery is required; the installation of the fixed base 23 can be completed simply by rotation.

[0078] During dismantling, operators only need to separate the upper support column 15 from the fixed base 23, and then rotate the fixed base 23 in the opposite direction to remove it completely from the ground. The entire process does not require destructive operations such as excavation, blasting, or heavy pile extraction, solving the problems of high cost of breaking traditional cast-in-place concrete foundations, large amount of construction waste, and easy bending and deformation and difficulty in reuse of permanent driven steel piles during extraction. It achieves non-destructive dismantling and complete recycling of the foundation, making the relocation work simple and efficient, and significantly reducing time, manpower and equipment costs.

[0079] In one embodiment, the bottom of the fixed base 23 is provided with a connecting cylinder, and the inner wall of the connecting cylinder is provided with a threaded connection portion; or, the bottom of the fixed base 23 is provided with a connecting pile 22, and the outer wall of the connecting pile 22 is provided with a threaded connection portion.

[0080] With this configuration, a connecting cylinder is provided at the bottom of the fixed base 23, and a threaded connection part is provided on its inner wall. The ground fixation is completed by screwing the matching connecting pile 22 into the connecting cylinder. Alternatively, a connecting pile 22 with an outer wall thread is directly provided at the bottom of the fixed base 23. The connecting pile 22 is screwed into the ground as a whole by rotation. Both schemes implant the fixed module 2 into the ground through pure rotational mechanical movement, avoiding the pit digging, formwork, and curing required by traditional cast-in-place concrete, or the violent driving operation required by permanent steel piles.

[0081] During disassembly, simply rotate the module in the opposite direction to remove it completely from the soil, making site restoration extremely simple and quick.

[0082] Secondly, no additional accessories are needed. The connecting pile 22 is driven directly into the ground by rotation, without the need for additional excavation. Furthermore, the screw-in installation causes minimal disturbance to the soil, and the ground can naturally recover after being pulled out, reducing damage to vegetation and the ecosystem.

[0083] Furthermore, the threaded connection can be screwed in and out by rotation, without the need for destructive dismantling. When the project is terminated or the position needs to be adjusted, the connecting cylinder or connecting pile 22 can be pulled out simply by rotating in the opposite direction.

[0084] In addition, because the connecting cylinder is screwed into the ground, it has a good anti-slip effect.

[0085] In one embodiment, an installation interface, such as a threaded hole, is provided on the outer edge of the top of the connecting cylinder. During installation, the photovoltaic bracket can be screwed in.

[0086] As a fourth implementation method, such as Figure 9 As shown, the prefabricated support module 1 is an integrally formed structure, including several connected beams, which are spliced ​​together to form a support foundation 16; the fixed module 2 is a support boss 24, which is provided in several ways, and the array of several support bosses 24 is installed at the bottom of the support foundation 16, and the cross-sectional area of ​​the support boss 24 gradually decreases along the direction away from the support foundation 16.

[0087] With this configuration, the prefabricated support module 1 is molded as a single piece, so that it is manufactured as a complete and robust unit in the factory and can be directly hoisted after arriving at the site, saving the tedious process and time of assembling a large number of rods 11 or plates on site.

[0088] During disassembly, the entire base unit can be lifted up. Compared to trusses that require individual bolt connections on site or concrete slabs that need to be spliced, this reduces on-site work and connection points, lowers quality risks caused by on-site human error, shortens installation and disassembly time, and makes the relocation work exceptionally efficient.

[0089] Furthermore, by gradually reducing the cross-sectional area of ​​the support boss 24 in the direction away from the support base 16, when subjected to downward pressure, the inclined surface of the support boss 24 can be used to transfer the force to the soil more evenly, making it easier to insert or place on the site surface, and stable contact can be achieved with a small amount of adjustment even on uneven ground.

[0090] Furthermore, by installing the support protrusions 24 in an array at the bottom of the support foundation 16 to form multiple independent support points, the weight and wind load of the photovoltaic array can be evenly distributed, reducing local stress concentration and lowering the risk of foundation cracking. By adjusting the array density and spacing of the support protrusions 24, they can be flexibly adapted to uneven terrain such as slopes and soft soil without the need for additional excavation or compaction.

[0091] In one embodiment, several connecting beams are spliced ​​as follows: Figure 10 The square shape shown is as follows: Figure 11 The sun shape shown is as follows: Figure 12 The I-shaped structure shown.

[0092] In one embodiment, an installation interface is provided at the top of the connecting beam.

[0093] In one embodiment, the cross-section of any connecting beam is trapezoidal, with its top dimension being larger than its bottom dimension.

[0094] Furthermore, reinforcing bars are embedded inside any connecting beam. During installation, the basic frame composed of reinforcing bars is placed inside the engineering formwork for integral casting.

[0095] In one embodiment, the mobile photovoltaic foundation also includes an intelligent leveling mechanism.

[0096] The intelligent leveling mechanism includes a sensing unit, a control unit, and an execution unit.

[0097] The sensing unit is used to monitor the tilt angle and pressure distribution data of the support component in real time; the control unit is connected to the sensing unit to receive data and generate leveling commands; the execution unit is connected to the control unit to receive leveling commands and fine-tune the height of the support component.

[0098] It can be explained that the sensing unit includes sensors installed on supporting components such as support piles, forming a grid-like layout, for real-time collection of status data of different areas. For example, tilt sensors are used to detect the overall levelness and issue an alarm when the levelness fails to meet the requirements. Another example is the use of pressure sensors to detect whether the force on each support point is uniform, preventing uneven settlement.

[0099] Furthermore, the control unit includes a control terminal, such as a microprocessor or PLC controller, for receiving data from the sensors and comparing it with a preset leveling threshold. If the data received by the sensor on a certain support pile exceeds the threshold, the actuator on the adjacent support pile is adjusted in time to achieve leveling.

[0100] Furthermore, the execution unit includes an electric drive assembly supporting the top of the pile.

[0101] For example, the electric drive assembly includes a linear actuator or a miniature hydraulic cylinder, communicatively connected to a control terminal. One end of the piston rod is hinged to the bottom of the precast support module, and the other end is movably connected to the hydraulic cylinder. Upon receiving instructions from the processor, it raises or lowers the height of the support point. In one embodiment, a network of drainage channels is pre-embedded or cast inside or on the surface of the precast concrete support module. The channels are interconnected, and at least one drainage outlet is provided on the side or corner of the foundation structure.

[0102] Furthermore, the drainage outlet is connected to the water collection device to effectively collect and guide the discharge of rainwater, condensate, or wastewater generated from cleaning photovoltaic panels, preventing water accumulation at the bottom of the foundation from softening the foundation, preventing long-term immersion of metal connectors in water from causing corrosion, and improving the overall stability and durability of the foundation.

[0103] In one embodiment, a metal grounding electrode is embedded inside the prefabricated support module 1. The upper end of the grounding electrode is provided with a standard threaded interface or quick connector, exposed in a junction box or specific location on the foundation surface, so as to facilitate connection with photovoltaic brackets and module frames via wires.

[0104] In one embodiment, the prefabricated support module has several cable channels inside for placing cables.

[0105] Secondly, the present invention also provides a photovoltaic power generation system, including the mobile photovoltaic foundation provided in the preceding aspect.

[0106] This setup is because the photovoltaic power generation system includes a mobile photovoltaic base, which has the same effect as a mobile photovoltaic base, and will not be elaborated further here.

[0107] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
