Description

Technical Field

[0001] This invention relates to the field of photovoltaic infrastructure technology, and more specifically, to a desert photovoltaic infrastructure and its construction method. Background Technology

[0002] In desert environments, the construction of photovoltaic (PV) foundations and the planting of vegetation are crucial means to achieve both photovoltaic utilization and ecological restoration. Currently, PV foundations typically employ pile foundations, where piles are driven into the desert to support the PV facilities. Simultaneously, some approaches explore planting vegetation around the PV facilities to improve the desert environment and achieve the dual goals of ecological benefits and energy utilization.

[0003] However, existing solutions face numerous challenges in practical application. On the one hand, the soft desert geology makes drilling holes prone to collapse, resulting in significant construction difficulties for existing pile foundations. Furthermore, the foundations are susceptible to vibration and swaying under wind force, and small-section foundations on soft ground are prone to settlement or tilting, severely impacting the stability of photovoltaic facilities. On the other hand, desert photovoltaic planting faces problems such as water shortage, loose soil texture, and wind and sand erosion, making it difficult for plants to take root and limiting their growth, thus hindering the achievement of ecological restoration goals. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a desert photovoltaic foundation and construction method.

[0005] In a first aspect, the present invention provides a desert photovoltaic foundation, comprising a foundation body and a sand-collecting hopper. The foundation body has a box-like structure and an internal accommodating cavity. The outer wall of the foundation body has a plurality of first openings communicating with the accommodating cavity. The sand-collecting hopper has an internal receiving cavity, and a second opening and a third opening communicating with the receiving cavity are formed on the sand-collecting hopper. The sand hopper is installed on the base body and blocks at least one of the first openings in the horizontal direction. It is connected to the first openings that are blocked through the second opening. The height of the lowest point of the third opening is higher than the height of the highest point of the corresponding first opening. When the two opposite side walls of the base body have the first openings that are not blocked by the sand hopper, the first openings located on the opposite side walls of the base body and the accommodating cavity constitute an air duct. Once sand accumulates in the receiving cavity of the sand hopper, the receiving cavity is used for planting greenery.

[0006] Optionally, along the height direction of the base body, the outer sidewall of the base body is provided with multiple layers of openings, each layer of the openings including at least one of the first openings.

[0007] Optionally, the first openings of two adjacent layers of the opening groups are arranged vertically in a corresponding manner; each sand hopper is configured to block the two corresponding first openings vertically.

[0008] Optionally, the upper and lower ends of the sand hopper are provided with plug-in members. The plug-in member located at the upper end of the sand hopper extends into the receiving cavity through the first opening at the upper end; the plug-in member located at the lower end of the sand hopper extends into the receiving cavity through the first opening at the lower end.

[0009] Optionally, along the height direction of the sand hopper, the sand hopper has a structure that is wider at the top and narrower at the bottom. When two sand hoppers are arranged adjacent to each other, the lower end of the sand hopper located above is accommodated inside the sand hopper located below, and the upper first opening of the two first openings corresponding to the sand hopper below is blocked.

[0010] Optionally, the sand hopper includes a first plate and two second plates; the two opposite ends of the first plate are respectively connected to the two second plates at an angle, and the first plate and the two second plates enclose each other to form the receiving cavity; the tops of the first plate and the two second plates enclose each other to form the third opening; the two second plates are each provided with the plug-in at the end away from the first plate, and form the second opening.

[0011] Optionally, the outer walls of the connectors at the upper ends of the two second plates are respectively fitted to the two inner walls opposite to the corresponding first openings.

[0012] Secondly, the present invention provides a construction method for a desert photovoltaic foundation, applicable to the desert photovoltaic foundation described above, comprising the following steps: The base body is placed in a predetermined location in the desert, so that during the ventilation process, the sand in the airflow of the base body is deposited into the accommodating cavity of the base body. Based on the height of the sand in the accommodating cavity, a sand hopper is installed on the base body so that the sand hopper blocks the first opening corresponding to the base body and the second opening of the sand hopper is connected to the corresponding first opening. When the sand level in the receiving cavity of the sand hopper reaches the first preset height, green plants are planted in the receiving cavity through the third inlet of the sand hopper.

[0013] Optionally, installing a sand collection hopper on the base body according to the sand level in the accommodating cavity includes: Once the sand level in the accommodating cavity reaches the second preset height, all the sand hoppers are installed on the foundation body. Alternatively, whenever the sand level in the accommodating cavity increases to a third preset height, a layer of the sand accumulation hopper is installed on the base body.

[0014] Optionally, after the weight of the sand in the receiving cavity reaches a preset weight, a photovoltaic array is installed on top of the base body, wherein the photovoltaic array is tilted relative to the base body.

[0015] Compared with related technologies, the beneficial effects of the present invention are as follows: During construction, the foundation does not need to be buried in a sand pit. Due to its box-like structure, it can be placed on the ground by its own weight, reducing construction difficulty. Furthermore, the air duct formed by the unobstructed first openings on the opposite side walls of the foundation and the accommodating cavity effectively collects sand and soil from the airflow. As the weight of the foundation increases over time, it reduces the problem of sand and soil loss causing foundation swaying or tilting, thereby improving the stability of the foundation.

[0016] Meanwhile, the sand-collecting hopper's receiving cavity is connected to the first opening via a second opening, and the lowest point of the third opening is higher than the highest point of the corresponding first opening. This structural design allows sand to flow from the first opening to the corresponding sand-collecting hopper and accumulate within it. Furthermore, once the sand in the hopper reaches a certain height, it prevents further overflow from the first opening, thus preventing sand loss. In addition, the receiving cavity within the sand-collecting hopper can be used for planting vegetation. Due to the protective function of the sand-collecting hopper, the sand will not easily be lost, providing a better soil environment for desert photovoltaic planting. Moreover, rainwater and washing water can be collected through the receiving cavity of the sand-collecting hopper and the receiving cavity of the foundation body, achieving water retention and evaporation prevention, providing a stable water source for plants, and further improving the conditions for desert photovoltaic planting.

[0017] In summary, this invention utilizes the unique structure of the foundation body and sand accumulation buckets, which not only reduces the construction difficulty of desert photovoltaic foundations and improves their stability, but also provides better soil and water conditions for desert photovoltaic planting, achieving the dual goals of stable operation of photovoltaic facilities and ecological restoration.

Therefore, they should not be construed as limitations on this invention.

[0022] The desert photovoltaic foundation of this invention includes a foundation body 100 and a sand accumulation hopper 200. The foundation body 100 has a box-like structure and an internal receiving cavity 101. The outer wall of the foundation body 100 has a plurality of first openings 1021 communicating with the receiving cavity 101. The sand accumulation hopper 200 has an internal receiving cavity 201, and a second opening 202 and a third opening 203 communicating with the receiving cavity 201 are formed on the sand accumulation hopper 200. The sand accumulation hopper 200 is installed on the foundation body 100 and blocks at least one of the first openings in the horizontal direction. The third opening 203 is connected to the first opening 1021 that is blocked by the sand hopper 200 through the second opening 202, and the height of the lowest end of the third opening 203 is higher than the height of the highest end of the first opening 1021. When there are first openings 1021 that are not blocked by the sand hopper 200 on the opposite side walls of the base body 100, the first openings 1021 on the opposite side walls of the base body 100 and the receiving cavity 101 constitute an air duct. When sand accumulates in the receiving cavity 201 of the sand hopper 200, the receiving cavity 201 is used to plant green plants.

[0023] Specifically, the shape of the basic body 100 can be a trapezoid, cube, cuboid, or pyramid, etc. There are no restrictions; it depends on the actual needs. For example, ... Figure 1 , 2 As shown, the base body 100 has a box-like structure, which is trapezoidal in shape, and has an internal accommodating cavity 101. The four side walls of the base body 100 are respectively provided with multiple first openings 1021 communicating with the accommodating cavity 101. The number and position of the first openings 1021 are not specifically limited and are determined according to actual needs. Figure 3 As shown, the sand hopper 200 has a receiving cavity 201 inside, and a second opening 202 communicating with the receiving cavity 201 is formed at the side end of the sand hopper 200, and a third opening 203 communicating with the receiving cavity 201 is formed at the upper end of the sand hopper 200.

[0024] In this embodiment, when the sand hopper 200 is installed on the base body 100, the lower end of the sand hopper 200 blocks at least one first opening 1021 in the horizontal direction and is connected to the blocked first opening 1021 through the second opening 202. The height of the lowermost end of the third opening 203 is higher than the height of the uppermost end of the corresponding first opening 1021. That is to say, due to the presence of the sand hopper 200, the direction of the sand in the accommodating cavity 101 flowing out of the first opening 1021 to the outside can be effectively changed. Finally, due to the obstruction of the sand hopper 200, the congestion effect at the first opening 1021 is increased to limit the flow of sand and restrict the sand from continuing to overflow from the first opening 1021.

[0025] In this embodiment, the foundation body 100 does not need to be buried in a sand pit during construction. Because it is a box-type structure, it can be placed on the ground by its own weight, reducing construction difficulty. Furthermore, the air duct formed by the unobstructed first opening 1021 on the opposite side walls of the foundation body 100 and the accommodating cavity 101 effectively collects sand from the airflow. As the weight of the foundation body 100 increases over time, it reduces the problem of sand loss causing foundation swaying or tilting, thus improving the stability of the foundation body 100.

[0026] Meanwhile, the receiving cavity 201 of the sand accumulation hopper 200 is connected to the first opening 1021 through the second opening 202, and the lowest point of the third opening 203 is higher than the highest point of the corresponding first opening 1021. This structural design allows sand to flow from the first opening 1021 to the corresponding sand accumulation hopper 200 and accumulate inside. Furthermore, when the sand in the sand accumulation hopper 200 reaches a certain height, it can prevent further overflow from the first opening 1021, thus preventing sand loss. In addition, the receiving cavity 201 within the sand accumulation hopper 200 can be used for planting vegetation. Due to the protective function of the sand accumulation hopper 200, the sand will not easily be lost, providing a better soil environment for desert photovoltaic planting. Moreover, rainwater and washing water can be collected through the receiving cavity 201 of the sand accumulation hopper 200 and the receiving cavity 101 of the base body 100, achieving water retention and evaporation prevention, providing a stable water source for plants, and further improving the conditions for desert photovoltaic planting.

[0027] In summary, by utilizing the unique structure of the foundation body 100 and the sand accumulation bucket 200, this invention not only reduces the construction difficulty of desert photovoltaic foundations and improves their stability, but also provides better soil and water conditions for desert photovoltaic planting, achieving the dual goals of stable operation of photovoltaic facilities and ecological restoration.

[0028] Optionally, along the height direction of the base body 100, the outer side wall of the base body 100 is provided with a multi-layer opening group 102, each opening group 102 including at least one first opening 1021.

[0029] Specifically, the number of layers in the opening group 102 and the number of first openings 1021 in each layer of the opening group 102 are not specifically limited, but are determined according to actual needs. For example... Figure 2 As shown, the opening group 102 has four layers, and each layer of the opening group 102 includes twenty-two first openings 1021.

[0030] In this optional embodiment, firstly, the presence of the multi-layer opening group 102 can effectively reduce wind load. When the first opening 1021 of the opening group 102 is not blocked by the sand collection hopper 200, the multi-layer opening group 102 can divide the airflow into multiple smaller airflows, thereby dispersing the impact force of the airflow and reducing the direct effect of wind on the foundation body 100, significantly reducing the impact of wind load on the foundation body 100. Secondly, the multi-layer opening group 102 can collect sand and soil in the airflow at different height levels. The weight of the foundation body 100 will continuously increase, effectively improving the efficiency of sand and soil collection.

[0031] It is important to understand that in a desert environment, one of the primary functions of the base 100 is as a sand barrier, effectively blocking and slowing down the movement of sand and thus protecting the surrounding area from sandstorms. In practical applications, when the base 100 performs its sand-blocking function, sand gradually accumulates on its windward and leeward sides, eventually forming sand dunes of a certain height. While this sand accumulation helps stabilize sand dunes, it can also bury the vegetation in the lower sand accumulation basins 200. Therefore, it is preferable to plant vegetation in the middle and upper layers of the sand accumulation basins 200 to mitigate this problem.

[0032] Optionally, the first openings 1021 of two adjacent opening groups 102 are arranged vertically and vertically; each sand hopper 200 is configured to block the two corresponding first openings 1021 vertically and vertically.

[0033] Specifically, such as Figure 2 As shown, the base body 100 has four layers of opening groups 102, each layer of opening group 102 has twenty-two first openings 1021, and the twenty-two first openings 1021 in adjacent layers of opening group 102 are arranged vertically in correspondence. Figure 4 , 5 As shown, when the sand hopper 200 is installed on the base body 100, each sand hopper 200 is configured to block the two corresponding first openings 1021 above and below.

[0034] In this optional embodiment, when each sand hopper 200 blocks two corresponding first openings 1021, the number of sand hoppers 200 can be effectively reduced, thereby reducing production costs.

[0035] Optionally, the upper and lower ends of the sand hopper 200 are provided with plug-in members 2051. The plug-in member 2051 located at the upper end of the sand hopper 200 extends into the receiving cavity 101 through the upper first opening 1021; the plug-in member 2051 located at the lower end of the sand hopper 200 extends into the receiving cavity 101 through the lower first opening 1021.

[0036] Specifically, the number of connectors 2051 can be one, two, or three, etc., without limitation, depending on actual needs. For example, Figure 4As shown, the upper end of the sand hopper 200 is provided with two opposing and spaced-apart plug-in pieces 2051. During installation, the plug-in pieces 2051 extend into the receiving cavity 101 through the upper first opening 1021 and are hooked onto the lower edge of the upper first opening 1021, with the effect as shown. Figure 5 As shown; at the same time, the lower end of the sand hopper 200 is provided with two opposite and spaced-apart plugs 2051. During installation, the plugs 2051 are inserted into the receiving cavity 101 through the lower first opening 1021 and abut against the lower edge of the lower first opening 1021.

[0037] In this optional embodiment, this top-to-bottom connection not only simplifies the installation process and improves installation efficiency, but also ensures that the sand hopper 200 can withstand the weight of sand accumulation and the influence of external wind forces during use, thus providing a stable and reliable structural foundation for the effective collection of sand and subsequent planting.

[0038] Optionally, along the height direction of the sand hopper 200, the sand hopper 200 has a structure that is wider at the top and narrower at the bottom. When two sand hoppers 200 are arranged adjacent to each other, the lower end of the sand hopper 200 located above is accommodated inside the sand hopper 200 located below, and blocks the upper first opening 1021 of the two first openings 1021 corresponding to the lower sand hopper 200.

[0039] In this optional embodiment, firstly, the shape, wider at the top and narrower at the bottom, allows for a larger opening area at the upper end of the sand collection hopper 200. This facilitates the nesting of the upper sand collection hopper 200 within the lower sand collection hopper 200, while still maintaining sufficient space at the third opening 203 of the lower sand collection hopper 200 for planting greenery, thereby maximizing space utilization and meeting ecological restoration needs. Secondly, the outer wall of the upper sand collection hopper 200 effectively guides rainwater and washing water into the lower sand collection hopper 200, further optimizing water collection efficiency and providing more abundant resources for plant growth. Finally, because the lower end of the upper sand collection hopper 200 is accommodated within the lower sand collection hopper 200 and blocks the first opening 1021 at the top, this nested structure creates a natural constraint, ensuring that sand flowing out of the upper sand collection hopper 200 generally falls into the lower sand collection hopper 200. This better restricts the flow of sand from the receiving cavity 101, thereby reducing sand loss from the receiving cavity 101.

[0040] Optionally, the sand hopper 200 includes a first plate 204 and two second plates 205; the two opposite ends of the first plate 204 are connected to the two second plates 205 at an angle, and the first plate 204 and the two second plates 205 enclose a cavity 101; the tops of the first plate 204 and the two second plates 205 enclose a third opening 203; each of the two second plates 205 is provided with a connector 2051 at the end away from the first plate 204, forming a second opening 202.

[0041] Specifically, such as Figure 3 As shown, the first plate 204 is a rectangular plate, with two second plates 205 perpendicularly connected to its two long sides, forming a cavity 101. Each second plate 205 can be considered a combination of a triangular plate and two parallelogram plates. The outer contour of the triangular plate is an acute triangle, and its long side connects to the long side of the first plate 204. Two parallelogram plates are parallel to and spaced apart along one short side of the triangular plate, and these parallelogram plates are inclined downwards and serve as connectors 2051. Thus, a second opening 202 is formed between the ends of the two triangular plates furthest from the first plate 204, and a third opening 203 is formed by the tops of the first plate 204 and the two second plates 205.

[0042] In this optional embodiment, the first plate 204 and the two second plates 205 are connected at an angle to form a receiving cavity 101, which not only provides a stable space for collecting sand and water, but also enhances the overall stability of the sand collection hopper 200 through this geometric structure. The tops of the first plate 204 and the second plate 205 together form a third opening 203, ensuring that sand, rainwater, and washing water can smoothly enter the receiving cavity 101, while providing ample space for planting greenery. In addition, the plug-in pieces 2051 provided on the two second plates 205 enable the sand collection hopper 200 to be quickly and securely installed on the base body 100, simplifying the installation process and improving installation efficiency. The design of the second opening 202 further optimizes the function of the sand collection hopper 200, allowing sand to flow smoothly from the base body 100 into the sand collection hopper 200, while restricting the outflow of sand, ensuring the effective collection and utilization of sand.

[0043] In this embodiment, the first plate 204 and the two second plates 205 can be an integrated structure or a detachable structure. No limitation is imposed here; it depends on the actual needs. Preferably, the first plate 204 and the two second plates 205 are an integrated structure.

[0044] Optionally, the outer walls of the connectors 2051 at the upper ends of the two second plates 205 are respectively fitted to the two inner walls opposite to the corresponding first openings 1021.

[0045] Specifically, the upper ends of the two second plates 205 are provided with two oppositely arranged plugs 2051, and the opposite end faces of the two plugs 2051 respectively fit against the two inner walls of the corresponding first opening 1021.

[0046] In this optional embodiment, the close fit between the outer wall of the connector 2051 at the upper end of the two second plates 205 and the inner wall of the first opening 1021 not only ensures that the sand collection hopper 200 can be quickly and accurately positioned during installation, but also further enhances the connection stability between the sand collection hopper 200 and the base body 100 by increasing the contact area and friction. This tightly fitted structural design effectively prevents the sand collection hopper 200 from loosening or shifting under the action of wind or other external forces, ensuring the stability of sand and water during collection and storage, and also providing a more stable supporting environment for subsequent planting, significantly improving the reliability and service life of the entire system.

[0047] Furthermore, the outer walls of the two second plates 205 located below can fit against the inner wall of the other sand hopper 200 to achieve a relative seal. Since the lower end of the bottom sand hopper 200 is not inserted into the other sand hopper 200, during installation, a flange can be used to seal the gap between the first opening 1021 and the lower end of the bottom sand hopper 200.

[0048] The desert photovoltaic foundation construction method of this invention, applied to the desert photovoltaic foundation as described above, includes the following steps: The base body 100 is placed in a preset location in the desert, so that during the ventilation process, the sand in the airflow of the base body 100 is deposited in the accommodating cavity 101 of the base body 100. In this step, when placing the base 100, it is necessary to select a suitable location based on local wind direction, terrain, and the layout of photovoltaic facilities to ensure that the base 100 can fully perform its functions.

[0049] According to the height of the sand in the accommodating cavity 101, a sand hopper 200 is installed on the base body 100 so that the sand hopper 200 blocks the corresponding first opening 1021 of the base body 100, and the second opening 202 of the sand hopper 200 is connected to the corresponding first opening 1021. In this step, maintenance personnel can observe the sand level inside the accommodating cavity 101 through the first opening 1021. Generally, a sand accumulation hopper 200 is installed before the sand level rapidly spreads to the first opening 1021 of the lowest opening group 102.

[0050] When the sand level in the receiving cavity 201 of the sand hopper 200 reaches the first preset height, green plants are planted in the receiving cavity 201 through the third inlet of the sand hopper 200. In this step, the sand in the receiving cavity 201 of the sand hopper 200 comes not only from the receiving cavity 101 of the base body 100, but also from the sand in the airflow. The first preset height is determined according to the third opening 203 of the sand hopper 200, and is generally about 5cm lower than the third opening 203.

[0051] Optionally, depending on the sand level within the accommodating cavity 101, a sand accumulation hopper 200 is installed on the foundation body 100, including: When the sand level in the accommodating cavity 101 reaches the second preset height, all sand hoppers 200 are installed on the base body 100, and the effect is as follows. Figure 6 As shown; or, whenever the sand level in the accommodating cavity 101 increases to a third preset height, a sand accumulation hopper 200 is installed on the base body 100, with the effect as follows. Figure 4 As shown.

[0052] In this embodiment, the first installation method of the sand accumulation hopper 200 can be regarded as a one-time installation, and the second preset height is determined according to actual needs, generally not exceeding the first opening 1021 of the lowest layer opening group 102; the second installation method of the sand accumulation hopper 200 can be regarded as a layered, multiple installation, and the third preset height generally does not exceed the distance between two adjacent layers of opening groups 102. The two implementation methods can be selected according to actual needs.

[0053] Optionally, after the weight of the sand in the receiving cavity 201 reaches a preset weight, a photovoltaic array 300 is installed on top of the base body 100, wherein the photovoltaic array 300 is tilted relative to the base body 100.

[0054] In this embodiment, the photovoltaic array 300 is installed after the sand reaches a preset weight, ensuring sufficient stability of the foundation 100 to effectively support the weight of the photovoltaic array 300 and reduce swaying or tilting caused by foundation instability, thereby improving the operational reliability of the photovoltaic facility. Secondly, the tilted design of the photovoltaic array 300 not only optimizes the light-receiving angle of the photovoltaic panels and improves power generation efficiency, but also better guides rainwater and washing water along the tilted surface of the photovoltaic panels, allowing them to collect smoothly and flow into the sand collection bin 200. This design fully utilizes natural rainfall and washing water, further increasing the moisture content of the sand in the sand collection bin 200, improving plant growth conditions, reducing water waste, and enhancing the ecological and economic benefits of the entire system.

[0055] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
