[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] like Figures 1 to 5 As shown, the photovoltaic power station that can avoid erosion in desert areas according to the embodiment of the present invention comprises a plurality of first columns 1, a plurality of second columns 2, a photovoltaic panel 3, a first partition 4 and a second partition 5. The plurality of first columns 1 are arranged at intervals along the first direction, the plurality of second columns 2 are arranged at intervals along the first direction, the first columns 1 and the second columns 2 are arranged at intervals in the second direction, the height of the first column 1 is higher than the second column 2, and the photovoltaic panel 3 is obliquely arranged on the first column 1 and the second column 2.

[0027] The first partition 4 is connected to at least one of the first column 1 and the second column 2 and is arranged horizontally. One end of the first partition 4 is connected to the bottom end of the photovoltaic panel 3. The second partition 5 is connected to at least one of the first column 1 and the second column 2 and is located below the first partition 4. The second partition 5 is arranged parallel to the first partition 4. The second partition 5 is used to stop downward on the sandy ground in the desert area. The first partition 4 and the second partition 5 define a wind passage, wherein the first direction is perpendicular to the second direction, and the first direction and the second direction are as follows. Figure 1 shown.

[0028] It should be noted that in the relevant technology, the airflow in the edge area of ​​the photovoltaic power station is guided by the downward tilt of the photovoltaic panels, and the collected flow is accelerated to form a vortex, which leads to erosion under the photovoltaic panels, forming wind erosion pits with the lower edge of the photovoltaic panels as the axis. The base columns of the photovoltaic panels are eroded by the wind and sand flow and exposed 20 to 80 cm above the ground, which seriously threatens the stability of the fixed structure of the photovoltaic modules.

[0029] When the photovoltaic power station of the embodiment of the present invention is in use, the second partition 5 is stopped on the sandy ground in the desert area. Since the first partition 4 is parallel to the second partition 5, the cross-sectional area of ​​the wind passage formed between the first partition 4 and the second partition 5 is equal everywhere. When the wind blows through the wind passage along the direction of the first column 1 toward the second column 2, the phenomenon of flow collection acceleration and vortex flow will not be formed at the bottom of the photovoltaic panel 3, which can avoid the occurrence of erosion under the photovoltaic panel 3, and further avoid the column of the photovoltaic panel 3 from being exposed to the surface due to erosion by the wind and sand flow, effectively ensuring the structural stability of the photovoltaic power station. Therefore, the photovoltaic power station of the embodiment of the present invention can avoid the occurrence of erosion in the desert area, greatly improve the structural stability of the column, and has the advantage of high safety in use.

[0030] In some embodiments, the second partition 5 is connected to the first column 1 and the second column 2 in an adjustable manner in the vertical direction.

[0031] The terrain of desert areas may be different. By adjusting the position of the second partition 5, it can better adapt to the ground at different heights and ensure the overall stability of the photovoltaic power station. If a part of the photovoltaic power station needs maintenance or overhaul, the adjustable second partition 5 makes this work more convenient because it can be temporarily adjusted to provide a larger operating space.

[0032] In some embodiments, a motor 6 is provided on the first partition plate 4, the output shaft of the motor 6 extends in the vertical direction, a screw 7 extending in the vertical direction is provided on the output shaft of the motor 6, a threaded through hole extending in the vertical direction is opened on the second partition plate 5, and the screw 7 is threadedly matched with the threaded through hole.

[0033] like Figures 2 to 4As shown, a screw rod 7 extending in the vertical direction is provided on the output shaft of the motor 6, and a threaded through hole extending in the vertical direction is provided on the second partition 5. The screw rod 7 is threadedly matched with the threaded through hole, so that when the motor 6 drives the screw rod 7 to rotate, the second partition 5 can move in the vertical direction. The motor 6 is usually integrated with a control system, and the start, stop and rotation speed of the motor 6 can be controlled by the control system, so as to accurately control the position of the second partition 5. The motor 6 and the screw rod 7 on its output shaft cooperate with the threaded through hole on the second partition 5, so as to realize the automatic adjustment of the second partition 5 in the vertical direction. Driven by the motor 6, the screw rod 7 rotates, pushing the second partition 5 up and down. Since the motor 6 can be remotely controlled, the operator can adjust the position of the second partition 5 in the control center to adapt to different environmental conditions, such as changes in wind speed, wind direction or changes in the sand surface.

[0034] In some embodiments, the second partition 5 is provided with a plurality of first sliding holes and a plurality of second sliding holes extending in the vertical direction, and the plurality of first sliding holes correspond one-to-one to the plurality of first columns 1, and the first columns 1 can slideably cooperate with the first sliding holes in the vertical direction. The plurality of second sliding holes correspond one-to-one to the plurality of second columns 2, and the second columns 2 can slideably cooperate with the second sliding holes in the vertical direction. Since the first columns 1 and the second columns 2 can slide in cooperation with the corresponding sliding holes respectively, the stability of the operation of the second partition 5 can be improved, and the operation accuracy of the second partition 5 can be improved.

[0035] In some embodiments, the photovoltaic power station of the embodiment of the present invention further includes a first windshield 8 and a second windshield 9, both of which are disposed between the photovoltaic panel 3 and the first partition 4, and the first windshield 8 and the second windshield 9 are spaced apart in the first direction. Each of the first windshield 8 and the second windshield 9 is an arc-shaped plate, and the first windshield 8 and the second windshield 9 are gradually bent away from each other along the direction from the first column 1 to the second column 2.

[0036] like Figure 4 and Figure 5 As shown, the first wind shield 8 and the second wind shield 9 are arranged between the photovoltaic panel 3 and the first partition 4, which can effectively prevent the wind from directly impacting the photovoltaic panel 3 and reduce the impact of the wind on the photovoltaic power station structure. The first wind shield 8 and the second wind shield 9 are arc-shaped, and the first wind shield 8 and the second wind shield 9 are gradually bent away from each other along the direction from the first column 1 to the second column 2. The arc-shaped plate can make the wind flow produce a certain degree of separation when passing through the wind shield, which helps to guide the wind flow to one side, reduce the direct pressure of the wind on the photovoltaic panel 3, and reduce the impact of the wind. The existence of the wind shield can also increase the stability of the entire power station, especially when the wind force is strong, the wind shield can effectively reduce the load of the wind on the power station structure.

[0037] In some embodiments, the top of the first windshield 8 extends to the bottom surface of the photovoltaic panel 3, and the bottom of the first windshield 8 extends to the top surface of the first partition 4. This design forms a relatively strong integrated structure between the first windshield 8, the photovoltaic panel 3 and the first partition 4, thereby improving the protection capability of the power station against wind and sand.

[0038] In some embodiments, the top of the second windshield 9 extends to the bottom surface of the photovoltaic panel 3, and the bottom of the second windshield 9 extends to the top surface of the first partition 4. This design forms a relatively strong integrated structure between the second windshield 9, the photovoltaic panel 3 and the first partition 4, thereby improving the protection capability of the power station against wind and sand.

[0039] In some embodiments, a plurality of air holes 401 arranged at intervals are provided on the first partition plate 4 .

[0040] like Figure 4 and Figure 5 As shown, the setting of the air hole 401 can reduce the wind resistance to the first partition 4 and the photovoltaic panel 3, so that the wind can smoothly pass through the air hole 401 on the first partition 4 into the wind channel, and then flow out from the wind channel, thereby reducing the pressure on the overall structure of the photovoltaic power station. Therefore, through the design of the air hole 401, the wind load can be effectively reduced, and the damage to the power station structure caused by excessive wind force can be reduced. The air hole 401 can guide the wind flow and change the direction of the wind, thereby reducing the direct impact of the wind on the photovoltaic panel 3 and the column. The air hole 401 can also help the photovoltaic power station to dissipate heat better, keep the temperature of the power station within a reasonable range, and help to extend the service life of the photovoltaic panel 3 and other electronic equipment.

[0041] Optionally, multiple air holes 401 are evenly or unevenly arranged on the first partition 4, and these holes can be circular, square or other shapes, depending on the design needs and functional requirements. The size and number of the air holes 401 can be adjusted according to the wind speed, wind direction and dust conditions at the location of the photovoltaic power station to ensure the best protection effect. The interval arrangement of the air holes 401 can optimize the path of the wind flow through the partition and reduce the impact on the photovoltaic power station.

[0042] Optionally, the plurality of air holes 401 are divided into a plurality of hole groups, the plurality of hole groups are arranged at intervals along the second direction, and each hole group includes a plurality of air holes 401 arranged at intervals along the first direction.

[0043] like Figure 4 and Figure 5As shown, the photovoltaic power station of the embodiment of the present invention can optimize the wind flow more effectively by grouping the wind holes 401, and each hole group can serve as an independent wind flow regulation unit to adjust the path and speed of the wind flow as needed. The grouping design allows engineers to flexibly adjust the size, position and number of hole groups according to specific environmental conditions and power station layout requirements to achieve optimal wind flow management and structural stability. The wind holes 401 in each hole group can reduce the wind load in the local area, thereby reducing the pressure on the partition and protecting the power station structure from wind damage. The grouped design of the wind holes 401 helps prevent the accumulation of sand and dust in specific areas of the partition. By adjusting the arrangement and size of the wind holes 401 in the hole group, the direction and speed of the wind flow can be controlled to achieve more effective wind flow dispersion and decompression.

[0044] Optionally, the diameters of each air hole 401 in the hole group are the same.

[0045] The uniform diameter design simplifies the design and manufacturing process of the partition, reducing production costs and complexity. The same diameter of the air holes 401 can ensure that the airflow passes through the partition more evenly, avoiding uneven airflow distribution caused by different hole diameters. The uniform size of the air holes 401 is more convenient for cleaning and maintenance, because all holes are of the same size and can be operated with standardized tools.

[0046] In some embodiments, the diameter of the air holes 401 in the hole group gradually decreases from the first column 1 to the second column 2 .

[0047] In the hole group, starting from the hole close to the first column 1, the aperture gradually decreases until it reaches the diameter of the hole close to the second column 2. The reduction in aperture can be linear, exponential or in the form of other mathematical functions so that engineers can adjust it according to actual needs. As the aperture gradually decreases, the wind flow will be accelerated to a certain extent when passing through the hole group, which helps to guide the direction of the wind flow and reduce the direct impact on the photovoltaic panel 3. The gradual reduction in aperture helps to optimize the airflow inside the photovoltaic power station, so that the wind can pass through the entire power station more smoothly and reduce the accumulation of wind and sand. Gradually reducing the aperture in the direction from the first column 1 to the second column 2 can better adapt to wind erosion under different environmental conditions and improve the adaptability and durability of the power station.
