Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to an adjustable slope photovoltaic support. Background Technology

[0002] With the rapid development of the photovoltaic power generation industry, photovoltaic systems are mainly installed in relatively open areas such as mountains, water surfaces, and deserts. However, as available land resources for photovoltaic applications continue to decrease and management requirements for photovoltaic land use become increasingly stringent, photovoltaic application sites need more flexible layouts and the reuse of idle land resources. To effectively utilize land resources, photovoltaic modules can be installed on slopes along highways, airports, or reservoir back slopes, without requiring additional land. This makes slopes a highly efficient renewable energy development model for utilizing existing space resources, helping to alleviate land scarcity and achieving a win-win situation for green development and spatial optimization.

[0003] However, in related technologies, traditional photovoltaic supports generally adopt steel structures, and the foundations adopt the form of bored piles, independent foundations, etc. The foundations resist the upper loads by relying solely on the piles, so there are many pile foundations, the burial depth is relatively deep, and the damage to the original landform is relatively large. Utility Model Content

[0004] This application provides an adjustable slope photovoltaic support system, which to some extent improves the technical problem in related technologies where the foundation resists the upper load by relying solely on piles, resulting in a large number of pile foundations, deep burial depth, and significant damage to the original landform.

[0005] This application provides an adjustable slope photovoltaic support system, which includes multiple installation units arranged side-by-side and spaced apart along a first direction and multiple purlins arranged side-by-side and spaced apart along a second direction. The first direction is perpendicular to the second direction. The installation unit includes: A tie beam and a foundation assembly are connected, the foundation assembly is embedded in the slope, and the tie beam is attached to the slope surface. Multiple support components are spaced apart on the top of the tie beam along a second direction; along the first direction, the support components of the multiple installation units are correspondingly arranged to form multiple support rows, and multiple purlins are arranged one-to-one with the multiple support rows. The purlins are connected to the corresponding support rows, and at least two purlins form an installation position. Multiple photovoltaic modules can be installed side by side in the installation position along the first direction. The relative positions of the purlin and the support assembly are adjustable along a direction perpendicular to the slope.

[0006] In some embodiments, the support assembly includes a column pier and an embedded part, the column pier being connected to the tie beam, a portion of the embedded part being embedded in the column pier, a portion of the embedded part extending out of the column pier away from the tie beam, and the purlin being connected to the embedded part.

[0007] In some embodiments, the embedded component includes an anchor bar, an anchor plate, and a connecting plate. The anchor bar and the connecting plate are respectively disposed on both sides of the anchor plate. The anchor bar is embedded in the column pier. The anchor plate is attached to the side of the column pier away from the tie beam. The purlin is connected to the connecting plate.

[0008] In some embodiments, the connecting plate is provided with a plurality of first connecting holes, and the purlin is provided with a plurality of second connecting holes. The plurality of first connecting holes are spaced apart along a direction perpendicular to the tie beam, and the plurality of second connecting holes are spaced apart along a direction perpendicular to the tie beam. The second connecting holes may be selectively configured to correspond to one of the first connecting holes. The support assembly further includes a first fastener, which passes through the first connecting hole and the corresponding second connecting hole.

[0009] In some embodiments, the connecting plate includes a first connecting portion and two second connecting portions disposed on both sides of the first connecting portion. The first connecting portion and the two second connecting portions are both connected to the anchor plate, and a plurality of first connecting holes are disposed in the first connecting portion.

[0010] In some embodiments, the foundation, the tie beam, and the column pier are all made of reinforced concrete.

[0011] In some embodiments, the slope photovoltaic support also includes a second fastener that connects the purlin to the photovoltaic module.

[0012] In some embodiments, the base component includes a plurality of base members, which are spaced apart from the tie beam along the second direction.

[0013] In some embodiments, the base component includes three base members, which are respectively disposed at both ends and the middle of the tie beam.

[0014] In some implementations, the two purlins form a mounting position.

[0015] The beneficial effects of this application are as follows: This application provides an adjustable slope photovoltaic support system. Because the foundation components are embedded in the slope and the tie beams are attached to the slope surface, most of the resistance to the upper load is borne by the friction between the tie beams and the slope surface, with only a small portion borne by the foundation components. Therefore, the number of foundation components can be reduced, resulting in lower requirements for the bearing capacity of the foundation and shallower embedment depth, thus reducing the destructive impact on the slope. Since the relative positions of the purlins and support components are adjustable along the direction perpendicular to the slope surface, the overall height of the slope photovoltaic support system can be adjusted according to the elevation of the site, making the construction of the slope photovoltaic support system faster, the installation more convenient, and applicable to a wider range of terrains.

[0028] Please see Figure 1 This application provides an adjustable slope photovoltaic support 10, which is installed on a slope 20 and used to install photovoltaic modules 300, i.e., solar panels. The slope photovoltaic support 10 provided in this application can reduce the destructive impact on the slope 20.

[0029] Please see Figures 1-3In this embodiment, the slope photovoltaic support 10 includes multiple installation units 100 arranged side-by-side and spaced apart along a first direction X and multiple purlins 200 arranged side-by-side and spaced apart along a second direction Y, where the first direction X is perpendicular to the second direction Y. Each installation unit 100 includes a tie beam 110, a foundation component 120, and multiple support components 130. The tie beam 110 and the foundation component 120 are connected, the foundation component 120 is embedded within the slope 20, and the tie beam 110 is attached to the slope surface of the slope 20. Multiple support components 130 are spaced apart on top of the tie beam 110 along the second direction Y.

[0030] Along the first direction X, multiple support components 130 of the mounting units 100 are correspondingly arranged to form multiple support rows. Multiple purlins 200 are correspondingly arranged to each of the multiple support rows, and the purlins 200 are connected to the corresponding support rows. At least two purlins 200 form a mounting position, and multiple photovoltaic modules 300 can be installed side by side in the mounting position along the first direction X. Furthermore, the relative positions of the purlins 200 and the support components 130 are adjustable along the direction perpendicular to the slope.

[0031] Optionally, two purlins 200 can form an installation position, that is, when the photovoltaic module 300 is installed in the installation position, the corresponding two purlins 200 respectively support the photovoltaic module 300 on both sides along the second direction Y.

[0032] The slope photovoltaic support 10 provided in this application embodiment has a base component 120 embedded within the slope 20, and a tie beam 110 attached to the slope surface of the slope 20. Therefore, most of the resistance to the upper load is borne by the friction between the tie beam 110 and the slope surface, with only a small portion borne by the base component 120. Consequently, the number of base components 120 can be reduced, thus lowering the requirement for foundation bearing capacity and allowing for shallower embedment depths, reducing the destructive impact on the slope 20. Furthermore, since the relative positions of the purlins 200 and the support components 130 are adjustable along a direction perpendicular to the slope surface, the overall height of the slope photovoltaic support 10 can be adjusted according to the terrain, making construction faster, installation more convenient, and applicable to a wider range of terrains.

[0033] It should be noted that drainage pipes can be pre-embedded in the photovoltaic support 10 on the slope, which can simultaneously solve the slope drainage problem and organize the drainage of rainwater collected by the photovoltaic modules 300, thereby improving the soil and water loss and protection of the slope 20. In addition, multiple photovoltaic modules 300 can be installed at intervals or designed to allow light transmission, thus preserving some space for vegetation growth and reducing the disturbance to the slope ecology.

[0034] Please see Figure 3 and Figure 4In some embodiments, the base component 120 includes multiple base members 121, which are spaced apart along the second direction Y on the tie beam 110. As mentioned above, since the slope photovoltaic support 10 provided in this application embodiment is mostly resisted by the friction between the tie beam 110 and the slope surface, and only a small part is resisted by the base component 120, the number of base members 121 can be reduced.

[0035] Optionally, the foundation component 120 includes three foundation members 121, which are respectively located at both ends and the middle of the tie beam 110. That is, two foundation members 121 are located at both ends of the tie beam 110, and the remaining foundation member 121 is located in the middle of the tie beam 110, improving the uniformity of stress distribution. Since each tie beam 110 only has three foundation members 121, the requirement for foundation bearing capacity is low, and the burial depth of the foundation component 120 can be shallow, reducing the destructive impact on the slope 20 and also serving as slope protection to prevent soil erosion. Therefore, it can be used for both ecological restoration and to address land scarcity issues. Specifically, the burial depth of the foundation member 121 can be 0.5m, and the dimensions of the foundation member 121 can be 0.2m (width) * 0.4m (length) * 0.5m (height).

[0036] Furthermore, traditional photovoltaic support foundations in related technologies generally use bored pile foundations, which require mechanical construction but can only be used in areas with gentle slopes. In addition, construction roads for mechanical equipment need to be built, increasing project costs. In the slope photovoltaic support 10 provided in this application embodiment, the number of foundation components 121 is small, the burial depth is shallow, construction is convenient, large mechanical equipment is not required, and only simple construction access roads need to be built, reducing project costs.

[0037] In some embodiments, the support assembly 130 includes a column base 131 and an embedded part 132. The column base 131 is connected to the tie beam 110. A portion of the embedded part 132 is embedded in the column base 131 and a portion of the embedded part 132 extends out of the column base 131 away from the tie beam 110. The purlin 200 is connected to the embedded part 132.

[0038] The foundation component 121, tie beam 110, and column pier 131 can all be made of reinforced concrete, while the embedded part 132 can be made of steel and reinforcing bars. The column pier 131 and the embedded part 132 can be cast as a whole. In other words, the slope photovoltaic support 10 provided in this application embodiment is made of common building materials, which are readily available, easy to construct, and ensure construction quality. It has a simple structure, uses less steel, and saves on project costs. Furthermore, the reinforced concrete support is resistant to ultraviolet rays, salt and alkali, and corrosion, making it particularly suitable for harsh environments such as saline-alkali land, tidal flats, high altitudes, and permafrost regions, exhibiting strong weather resistance.

[0039] The tie beam 110 and the foundation component 120 can be cast as a whole, reducing the risk of anchor bolt loosening. Compared with the photovoltaic support using steel structure + pile foundation in related technologies, the slope photovoltaic support 10 provided in this application embodiment does not require complex pile foundation construction machinery and the installation of complex upper components, effectively shortening the construction cycle and having better overall integrity than steel structure support.

[0040] Traditional steel structure supports in related technologies are usually designed based on the design wind pressure, without considering the impact of extreme wind weather. The slope photovoltaic support 10 provided in this application embodiment has a large overall stiffness and a high safety reserve. The overturning and sliding resistance of the support is better than that of traditional steel structure supports. Extreme wind weather has less impact on the reinforced concrete support, which can reduce economic losses. It is especially suitable for steep slopes 20.

[0041] Optionally, the slope photovoltaic support 10 may also include tie rods 400 for connecting two adjacent purlins 200. See also... Figure 5 The embedded part 132 may include anchor bar 1321, anchor plate 1322 and connecting plate 1323. The anchor bar 1321 and connecting plate 1323 are respectively located on both sides of the anchor plate 1322. The anchor bar 1321 is embedded in the column pier 131. The anchor plate 1322 is attached to the side of the column pier 131 away from the tie beam 110. The purlin 200 is connected to the connecting plate 1323.

[0042] Please see Figure 5 In some embodiments, the connecting plate 1323 is provided with a plurality of first connecting holes 1323a, and the purlin 200 is provided with a plurality of second connecting holes 210. The plurality of first connecting holes 1323a are spaced apart along a direction perpendicular to the tie beam 110, and the plurality of second connecting holes 210 are spaced apart along a direction perpendicular to the slope surface of the slope 20. The second connecting holes 210 may be selectively configured to correspond to one of the first connecting holes 1323a. The support assembly 130 also includes a first fastener 133, which passes through the first connecting hole 1323a and the corresponding second connecting hole 210.

[0043] Since multiple first connecting holes 1323a and multiple second connecting holes 210 are spaced apart along a direction perpendicular to the slope, adjusting the relative position of the purlin 200 with respect to the connecting plate 1323 allows the second connecting hole 210 to be selectively matched with one of the first connecting holes 1323a, thereby achieving a fixed connection between the connecting plate 1323 and the purlin 200. When installing the purlin 200, its relative position to the connecting plate 1323 can be adjusted according to the terrain, allowing the second connecting hole 210 to connect with first connecting holes 1323a at different heights, thus giving the slope photovoltaic support 10 a certain degree of height adjustment. This adjustment function makes the support construction faster, installation more convenient, and applicable to a wider range of terrains.

[0044] Please see Figure 6 The connecting plate 1323 includes a first connecting portion and two second connecting portions disposed on both sides of the first connecting portion. Both the first connecting portion and the two second connecting portions are connected to the anchor plate 1322. Multiple first connecting holes 1323a are provided in the first connecting portion. Optionally, the connecting plate 1323 may be made of channel steel. The first fastener 133 may include bolts and nuts. The bolts pass through the first connecting holes 1323a and their corresponding second connecting holes 210, and the nuts are tightened to achieve a fixed connection between the purlin 200 and the connecting plate 1323. The slope photovoltaic support 10 also includes a second fastener 310, which connects the purlin 200 and the photovoltaic module 300. The second fastener 310 may also include bolts and nuts, that is, both the photovoltaic module 300 and the purlin 200 are provided with through holes, the bolts are inserted into the through holes of the photovoltaic module 300 and the purlin 200, and the nuts are tightened to achieve a fixed connection between the purlin 200 and the photovoltaic module 300.

[0045] In summary, the beneficial effects of the embodiments of this application are as follows: 1) Integration of slope photovoltaic support 10 with slope protection: In the construction of new slopes, the slope photovoltaic and slope protection functions are innovatively combined. In the slope photovoltaic support 10 arranged on the slope, the tie beam 110 is both a component of the photovoltaic support and a grid beam for slope protection.

[0046] 2) Innovative approach to terrain utilization and ecological restoration: Utilizing slopes (such as mountain slopes, roadside slopes, and mine restoration slopes) – “marginal land” that traditional photovoltaic systems struggle to cover – to address the scarcity of flat land resources. Photovoltaic systems are constructed on slopes in mining areas or geological disaster zones, reinforcing the slope with support foundations. Simultaneously, the photovoltaic modules reduce rainwater erosion, creating conditions for vegetation restoration (“Photovoltaic + Ecological Restoration” model).

[0047] 3) Policy and Market Compatibility: It aligns with China's "photovoltaic + ecological governance" policy and is easy to obtain environmental impact assessment approvals. It has broad application scenarios in mountainous areas and "photovoltaic + mine restoration" projects in China.

[0048] 4) The slope photovoltaic support 10 can be widely used in existing slope scenarios. It is superior to steel structure photovoltaic support in terms of construction convenience, durability, environmental friendliness and cost economy.

[0049] 5) The slope photovoltaic support system 10, through material optimization and structural innovation, overcomes the limitations of traditional steel structure supports in complex terrain. It combines technological breakthroughs with practical engineering value, representing a typical example of the integration of "new energy + infrastructure." Its application potential will be further unleashed in the future with advancements in intelligent construction technology and green materials.
