Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and more specifically to a photovoltaic power station in desert areas that can prevent sand dunes from shifting forward. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, is increasingly widely used in desert regions. However, the arid climate, scarce rainfall, and frequent sandstorms unique to desert areas pose significant challenges to the safe and stable operation of photovoltaic power plants. Sandstorms cause erosion and dune movement beneath the photovoltaic panels, forming wind erosion pits (grooves) along the lower edge of the photovoltaic panels, exposing the foundation pillars. This severely affects the stability of the photovoltaic module's fixing structure. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a photovoltaic power station in desert areas that can prevent sand dunes from moving forward.

[0005] The photovoltaic power station for desert areas that can prevent sand dune advance according to the present invention includes multiple first columns, multiple second columns, photovoltaic panels, and multiple deflector columns. The multiple first columns are arranged at intervals along a first direction, and the multiple second columns are arranged at intervals along the first direction. The first columns and the second columns are arranged at intervals in a second direction, and the height of the first columns is higher than that of the second columns. The photovoltaic panels are inclinedly mounted on the first columns and the second columns. The multiple deflector columns are spaced apart on the side of the second column away from the first column in the second direction. Each deflector column includes a column body and multiple deflector rods. The multiple deflector rods are spaced apart on the outer circumferential surface of the column body, and the axial direction of the deflector rods is perpendicular to the axis of the column body, wherein the first direction is perpendicular to the second direction.

[0006] In some embodiments, the plurality of turbulence columns are divided into a plurality of flow groups, the plurality of flow groups are arranged at intervals in the second direction, and each flow group includes a plurality of turbulence columns arranged at intervals along the first direction.

[0007] In some embodiments, the turbulence columns in two adjacent flow groups are arranged alternately in the first direction.

[0008] In some embodiments, the plurality of spoiler bars are divided into a plurality of bar groups, the plurality of bar groups being arranged at intervals along the axial direction of the column body, the bar group including a plurality of spoiler bars arranged at intervals along the circumferential direction of the column body.

[0009] In some embodiments, the photovoltaic power station in the desert area that can prevent sand dune movement in the present invention further includes a first partition and a second partition. The first partition is connected to at least one of the first column and the second column and is arranged horizontally. One end of the first partition is connected to the bottom end of the photovoltaic panel. The second partition is connected to at least one of the first column and the second column and is located below the first partition. The second partition is arranged parallel to the first partition and is used to stop downwards against the sandy ground in the desert area. A wind passage is defined between the first partition and the second partition.

[0010] In some embodiments, the second partition plate has a plurality of first sliding holes and a plurality of second sliding holes extending vertically. The plurality of first sliding holes correspond one-to-one with a plurality of first columns, and the first columns are slidably engaged with the first sliding holes in the vertical direction. The plurality of second sliding holes correspond one-to-one with a plurality of second columns, and the second columns are slidably engaged with the second sliding holes in the vertical direction. The first partition plate is provided with a motor, the output shaft of the motor extends vertically, and the output shaft of the motor is provided with a screw extending vertically. The second partition plate has a threaded through hole extending vertically, and the screw is threadedly engaged with the threaded through hole.

[0011] In some embodiments, the photovoltaic power station in the desert area that can prevent sand dune movement in the present invention further includes a first windbreak plate and a second windbreak plate. The first windbreak plate and the second windbreak plate are both disposed between the photovoltaic panel and the first partition plate. The first windbreak plate and the second windbreak plate are arranged at intervals in the first direction. Each of the first windbreak plate and the second windbreak plate is an arc-shaped plate, and the first windbreak plate and the second windbreak plate gradually bend away from each other along the direction from the first column to the second column.

[0012] In some embodiments, the first partition is provided with a plurality of spaced-apart air passages, the plurality of air passages are divided into a plurality of hole groups, the plurality of hole groups are spaced-apart along the second direction, and each hole group includes a plurality of air passages spaced-apart along the first direction.

[0013] In some embodiments, each of the air passages in the group of holes has the same diameter.

[0014] In some embodiments, the diameter of the air passage in the hole group gradually decreases along the direction from the first column to the second column.

[0015] In the photovoltaic power station of this invention, when wind blows from under the photovoltaic panels along the direction from the first column to the second column, the wind is turbulent by the turbulence columns, effectively dispersing the airflow. This prevents the formation of concentrated, accelerated, and swirling vortices at the bottom of the photovoltaic panels, avoiding erosion beneath the panels and the movement of sand dunes. Consequently, it prevents the photovoltaic panels' columns from being exposed due to wind and sand erosion, effectively ensuring the structural stability of the photovoltaic power station.

[0016] Therefore, the photovoltaic power station of this invention can avoid erosion and sand dune movement in desert areas, greatly improving the structural stability of the support column and having the advantage of high safety in use. Attached Figure Description

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figures 1 to 5As shown, the photovoltaic power station of this embodiment includes multiple first columns 1, multiple second columns 2, photovoltaic panels 3, and multiple baffle columns 4. The multiple first columns 1 are spaced apart along a first direction, the multiple second columns 2 are spaced apart along the first direction, and the first columns 1 and second columns 2 are spaced apart along a second direction. The height of the first columns 1 is higher than that of the second columns 2. The photovoltaic panels 3 are inclinedly mounted on the first columns 1 and the second columns 2. The multiple baffle columns 4 are spaced apart on the side of the second columns 2 away from the first columns 1 in the second direction. Each baffle column 4 includes a column body 401 and multiple baffle rods 402. The multiple baffle rods 402 are spaced apart on the outer circumferential surface of the column body 401, and the axial direction of the baffle rods 402 is perpendicular to the axis of the column body 401, wherein the first direction is perpendicular to the second direction.

[0026] In the photovoltaic power station of this embodiment, when wind blows from under the photovoltaic panel 3 along the direction from the first column 1 towards the second column 2, it is turbulent by the turbulence column 4, effectively dispersing the airflow. This prevents the formation of concentrated, accelerated, and swirling vortices at the bottom of the photovoltaic panel 3, avoiding erosion beneath the panel 3 and the movement of sand dunes. Consequently, it prevents the columns of the photovoltaic panel 33 from being exposed to the ground due to wind and sand erosion, effectively ensuring the structural stability of the photovoltaic power station.

[0027] Therefore, the photovoltaic power station of this invention can avoid erosion and sand dune movement in desert areas, greatly improving the structural stability of the support column and having the advantage of high safety in use.

[0028] In some embodiments, the plurality of turbulence columns 4 are divided into a plurality of flow groups, which are spaced apart in a second direction, and each flow group includes a plurality of turbulence columns 4 spaced apart in a first direction.

[0029] like Figures 1 to 3 As shown, the arrangement of multiple flow groups can create multiple turbulence zones on the leeward side of the photovoltaic panel. These turbulence zones can effectively disperse wind and sand flow, which is beneficial to improving the protection against erosion and the forward movement of sand and dust.

[0030] In some embodiments, the turbulence columns 4 in two adjacent flow groups are arranged alternately in a first direction. For example... Figure 3 As shown, the alternating arrangement of the turbulence columns 4 can create a more stable airflow pattern under the photovoltaic panel 3, further reducing the risk of erosion and sand dune movement.

[0031] In some embodiments, the plurality of spoiler rods 402 are divided into a plurality of rod groups, which are spaced apart axially on the column body 401. Each rod group includes a plurality of spoiler rods 402 spaced apart circumferentially on the column body 401.

[0032] The arrangement of multiple rod groups can form multiple turbulence points along the axial direction of the column body 401, which can generate more turbulence when the wind and sand flow passes by, increase the instability of the wind flow, and thus more effectively reduce the risk of erosion and sand dune movement.

[0033] In some embodiments, the photovoltaic power station of this invention further includes a first partition 5 and a second partition 6. The first partition 5 is connected to at least one of the first column 1 and the second column 2 and is horizontally arranged, with one end of the first partition 5 connected to the bottom end of the photovoltaic panel 3. The second partition 6 is connected to at least one of the first column 1 and the second column 2 and is located below the first partition 5, and is arranged parallel to the first partition 5. The second partition 6 is used to abut downwards against the sandy ground in the desert area, and a wind passage is defined between the first partition 5 and the second partition 6.

[0034] like Figure 2 As shown, in the photovoltaic power station of this embodiment, when in use, the second partition 6 is abutted against the sandy ground in the desert area. Since the first partition 5 is parallel to the second partition 6, the cross-sectional area of ​​the wind passage formed between the first partition 5 and the second partition 6 is equal everywhere. When the wind blows through the wind passage along the direction from the first column 1 to the second column 2, there will be no phenomenon of concentrated acceleration and swirling vortex at the bottom of the photovoltaic panel 3. This further avoids erosion below the photovoltaic panel 3 and the occurrence of sand dune forward movement, thereby preventing the columns of the photovoltaic panel 3 from being exposed to the ground due to wind and sand erosion, and further effectively ensuring the structural stability of the photovoltaic power station.

[0035] In some embodiments, the second partition 6 has a plurality of first sliding holes and a plurality of second sliding holes extending vertically. Each of the first sliding holes corresponds one-to-one with a plurality of first pillars 1, and the first pillars 1 are slidably engaged with the first sliding holes in the vertical direction. Each of the second sliding holes corresponds one-to-one with a plurality of second pillars 2, and the second pillars 2 are slidably engaged with the second sliding holes in the vertical direction. A motor 7 is mounted on the first partition 5. The output shaft of the motor 7 extends vertically, and a screw 8 extending vertically is mounted on the output shaft. A threaded through hole extending vertically is provided on the second partition 6, and the screw 8 is threadedly engaged with the threaded through hole.

[0036] The terrain in desert areas may vary. By adjusting the position of the second partition 6, it is possible to better adapt to different ground elevations, ensuring the overall stability of the photovoltaic power station. If a part of the photovoltaic power station requires maintenance or repair, the adjustable second partition 6 makes this work more convenient because it can be temporarily adjusted to provide more operating space.

[0037] Specifically, such as Figure 2As shown, a screw 8 extending vertically is provided on the output shaft of motor 7, and a threaded through hole extending vertically is provided on the second partition 6. The screw 8 is threadedly engaged with the threaded through hole, so that when motor 7 drives screw 8 to rotate, the second partition 6 can move vertically. Motor 7 is usually integrated with a control system, which can control the start, stop, and rotation speed of motor 7, thereby precisely controlling the position of the second partition 6. The engagement of motor 7 and the screw 8 on its output shaft with the threaded through hole on the second partition 6 enables automated adjustment of the second partition 6 in the vertical direction. Driven by motor 7, screw 8 rotates, pushing the second partition 6 up and down. Since motor 7 can be remotely controlled, operators can adjust the position of the second partition 6 from the control center to adapt to different environmental conditions, such as changes in wind speed, wind direction, or sand surface.

[0038] Since the first column 1 and the second column 2 can slide in conjunction with their respective sliding holes, the stability of the second partition 6 during operation can be improved, and the accuracy of the operation of the second partition 6 can be increased.

[0039] In some embodiments, the photovoltaic power station of the present invention further includes a first windbreak plate 9 and a second windbreak plate 10, both of which are disposed between the photovoltaic panel 3 and the first partition plate 5, and are spaced apart in a first direction. Each of the first windbreak plate 9 and the second windbreak plate 10 is an arc-shaped plate, and the first windbreak plate 9 and the second windbreak plate 10 gradually bend away from each other along the direction from the first column 1 to the second column 2.

[0040] like Figure 4 and Figure 5 As shown, the first windbreak plate 9 and the second windbreak plate 10 are positioned between the photovoltaic panel 3 and the first partition plate 5, effectively blocking direct wind impact on the photovoltaic panel 3 and reducing the wind's influence on the photovoltaic power station structure. The first windbreak plate 9 and the second windbreak plate 10 are arc-shaped, and they gradually bend away from each other along the direction from the first column 1 to the second column 2. The arc shape allows for a certain degree of separation of the airflow as it passes through the windbreak plate, helping to guide the airflow to one side, reducing the direct pressure of the wind on the photovoltaic panel 3, and reducing the wind's impact force. The presence of the windbreak plate also increases the stability of the entire power station, especially under strong wind conditions, where the windbreak plate effectively reduces the wind load on the power station structure.

[0041] In some embodiments, the first partition 5 is provided with a plurality of spaced air passage holes 501, the plurality of air passage holes 501 are divided into a plurality of hole groups, the plurality of hole groups are spaced apart along a second direction, and each hole group includes a plurality of air passage holes 501 spaced apart along a first direction.

[0042] like Figure 4 and Figure 5 As shown, the air vent 501 reduces wind resistance to the first partition 5 and the photovoltaic panel 3, allowing wind to flow smoothly through the air vent 501 into the air passage and then out, thus reducing pressure on the overall structure of the photovoltaic power station. Therefore, the design of the air vent 501 effectively reduces wind load and minimizes damage to the power station structure caused by excessive wind. The air vent 501 guides airflow and changes its direction, reducing direct impact on the photovoltaic panel 3 and the support column. The air vent 501 also helps the photovoltaic power station dissipate heat better, maintaining the station's temperature within a reasonable range, which helps extend the lifespan of the photovoltaic panel 3 and other electronic equipment.

[0043] The photovoltaic power station of this invention can more effectively optimize airflow by grouping the air passages 501. Each group of passages can act as an independent airflow regulation unit, adjusting the path and speed of the airflow as needed. This grouping design allows engineers to flexibly adjust the size, position, and number of passages according to specific environmental conditions and power station layout requirements to achieve optimal airflow management and structural stability. The air passages 501 in each group can reduce wind load in localized areas, thereby reducing pressure on the baffles and protecting the power station structure from wind damage. The grouped design of the air passages 501 helps prevent dust accumulation in specific areas of the baffles. By adjusting the arrangement and size of the air passages 501 in the group, the direction and speed of the airflow can be controlled, achieving more effective airflow dispersion and pressure reduction.

[0044] Optionally, multiple air passage holes 501 may be uniformly or non-uniformly arranged on the first partition 5. These holes can be circular, square, or other shapes, depending on design needs and functional requirements. The size and number of air passage holes 501 can be adjusted according to the wind speed, wind direction, and dust conditions at the location of the photovoltaic power station to ensure optimal protection. The spacing of the air passage holes 501 can optimize the path of airflow through the partition, reducing the impact on the photovoltaic power station.

[0045] In some embodiments, each air vent 501 in the vent group has the same diameter.

[0046] The uniform diameter design simplifies the design and manufacturing process of the baffle, reducing production costs and complexity. The consistent diameter of the air passages 501 ensures more uniform airflow through the baffle, avoiding uneven airflow distribution caused by different orifice diameters. The uniform size of the air passages 501 also facilitates cleaning and maintenance, as all holes are the same size and can be handled using standardized tools.

[0047] In some embodiments, the diameter of the air passage 501 in the hole group gradually decreases along the direction from the first column 1 to the second column 2.

[0048] In the aperture array, the aperture diameter gradually decreases from the aperture closest to the first pillar 1 until it reaches the diameter of the aperture closest to the second pillar 2. The decrease in aperture diameter can be linear, exponential, or other mathematical functions, allowing engineers to adjust it according to actual needs. As the aperture diameter gradually decreases, the airflow is accelerated to some extent when passing through the aperture array, helping to guide the airflow direction and reduce direct impact on the photovoltaic panels 3. The gradual decrease in aperture diameter helps optimize airflow within the photovoltaic power station, allowing wind to pass more smoothly throughout the entire power station and reducing the accumulation of sand and dust. Gradually decreasing the aperture diameter along the direction from the first pillar 1 to the second pillar 2 better adapts to wind erosion under different environmental conditions, improving the adaptability and durability of the power station.
