Description

Technical Field

[0001] This utility model relates to the field of wind and sand control, and in particular to a wind and sand control photovoltaic power station. Background Technology

[0002] The prevention and control of wind and sand disasters plays an important role in the governance of desert and Gobi areas in China and the efficient power generation of desert photovoltaic power stations. Desert photovoltaic power stations can not only make full use of desert solar energy resources to generate electricity, but also represent a new type of industrial desertification control method with great development potential.

[0003] In existing technologies, photovoltaic panels are installed facing south. Related studies have shown that when the prevailing wind direction is south or north, photovoltaic panels are effective in suppressing the movement of sand and dust on the ground. However, when the prevailing wind direction in a desert environment is inconsistent with the north-south wind, the sand control effect of photovoltaic panels is significantly reduced, and even wind erosion and increased dust accumulation on the panel surface occur, greatly affecting the effectiveness of photovoltaic sand control.

[0004] Most photovoltaic power stations use tall, upright nylon mesh sand barriers for sand control. However, existing nylon mesh sand barriers have limited effective protection range and unstable wind and sand control efficiency, which directly leads to poor wind and sand control effect and low power generation efficiency inside the photovoltaic power station.

[0011] Furthermore, the sand barrier is a nylon mesh, and the permeability of the sand barrier near the ground is higher than that of the sand barrier away from the ground.

[0012] Furthermore, the minimum horizontal distance W between the outer guardrail device and the inner photovoltaic device is W = Hcosγ / tanα; where H is the superposition height of the sand barrier and the double-sided photovoltaic panel, γ is the solar azimuth angle, and α is the solar altitude angle.

[0013] Furthermore, the misalignment distance between two adjacent columns of photovoltaic guardrail components is w2 = 1 / 2(L + w1); where L is the length of the photovoltaic guardrail component and w1 is the spacing between two adjacent photovoltaic guardrail components in one column.

[0014] Furthermore, the wind and sand protection photovoltaic power station also includes an automatic water collection and soil stabilization device, which includes a water reservoir and a water tank.

[0028] Combination Figure 1-2As shown, this utility model embodiment provides a wind and sand protection photovoltaic power station, including: an inner photovoltaic device and an outer guardrail device. The inner photovoltaic device includes multiple single-sided photovoltaic modules 2, which are arranged sequentially in the east-west direction and arranged in multiple rows in the north-south direction, with each single-sided photovoltaic module 2 facing south. The outer guardrail device includes multiple photovoltaic guardrail components 1, which are arranged on both sides of the inner photovoltaic device in the east-west direction. Each side of the photovoltaic guardrail components 1 is arranged sequentially in the north-south direction and arranged in multiple columns in the east-west direction, with adjacent columns of photovoltaic guardrail components 1 staggered. The photovoltaic guardrail components 1 include a sand barrier 6 and multiple double-sided photovoltaic panels 4. The sand barrier 6 is vertically set on the ground, and the multiple double-sided photovoltaic panels 4 are sequentially connected to the sand barrier 6 in the east-west direction and perpendicular to the ground.

[0029] In this embodiment of the invention, multiple single-sided photovoltaic modules 2 within the inner photovoltaic device are arranged facing south, similar to the inner ring arrangement of existing photovoltaic power stations. By installing photovoltaic guardrail components 1 on both sides of the inner photovoltaic device in the east-west direction, the photovoltaic guardrail components 1 can block wind and sand from winds that are not in the north-south direction, thus solving the problem of poor wind and sand protection in desert environments for existing photovoltaic power stations. Moreover, the sand barrier 6 is vertically set on the ground, which can block sand and gravel from the ground. Multiple double-sided photovoltaic panels 4 are connected to the sand barrier 6, which not only improves the power generation efficiency of the photovoltaic power station but also blocks wind and sand blowing towards the inner photovoltaic device, increasing the effective protection range of the inner photovoltaic device. This effectively prevents the single-sided photovoltaic modules 2 from being eroded by wind and the panel surface from accumulating dust, further improving the power generation efficiency of the entire photovoltaic power station. Secondly, the staggered arrangement of adjacent rows of photovoltaic guardrail components 1 further improves the wind and sand protection effect of the outer guardrail device. Furthermore, the sand barrier 6 is vertically installed on the ground, and the double-sided photovoltaic panel 4 is also perpendicular to the ground, which improves the overall sand-blocking effect of the photovoltaic guardrail assembly 1. Moreover, the double-sided photovoltaic panel 4 is oriented east-west and perpendicular to the ground, which maximizes its power generation efficiency and sand-blocking ability. Specifically, the double-sided photovoltaic panel 4 has the same volt-ampere output characteristics on both sides, which can realize double-peak power generation and reduce the fluctuation of the output power of the photovoltaic guardrail assembly 1.

[0030] In some practical application scenarios, the total height H of the sand barrier and bifacial photovoltaic module is preferably in the range of 2.6 to 3.6 meters, of which the height H1 of the bifacial photovoltaic panel 4 is preferably in the range of 2 to 2.5 meters, and the height H2 of the sand barrier 6 is preferably in the range of 0.5 to 1.0 meters.

[0031] Combination Figure 2-3 As shown, in some embodiments, the photovoltaic guardrail assembly 1 further includes two supports 3, which are respectively connected to the sand barrier 6 and the two sides of the multiple double-sided photovoltaic panels 4, and the supports 3 are vertically set on the ground.

[0032] In this embodiment, two brackets 3 are respectively connected to one side of the sand barrier 6 and to the outermost double-sided photovoltaic panel 4 above the sand barrier 6. Moreover, the brackets 3 are vertically set on the ground, which plays a stabilizing role for the entire photovoltaic guardrail assembly 1, further improving the blocking effect of the photovoltaic guardrail assembly 1 against wind and sand, and to a certain extent strengthening the connection between the sand barrier 6 and the double-sided photovoltaic panels 4 on both sides.

[0033] In some specific embodiments, the support 3 includes two streamlined torsion bodies 33 and a top 31. The two streamlined torsion bodies 33 are attached to each other and linearly and uniformly twisted along the sand barrier 6 near the ground to the end of the double-sided photovoltaic panel 4 away from the ground. The top 31 is connected above the two streamlined torsion bodies 33.

[0034] In this embodiment, the two streamlined torsion bodies 33 adopt a linear uniform torsion streamlined design, which twists and rises from the bottom of the sand barrier 6 to the top of the double-sided photovoltaic panel 4, which can make the incoming desert wind swirl and rise, thereby reducing the impact of the wind on the support and strengthening the ability of the photovoltaic guardrail assembly 1 to block wind and sand. The top 31 is connected above the two streamlined torsion bodies 33, which facilitates the connection of multiple double-sided photovoltaic panels 4.

[0035] In some specific embodiments, the two streamlined torsion bodies 33 are in a double helix shape, and the top 31 is in a conical shape.

[0036] In this embodiment, the two streamlined torsion bodies 33 in a double helix shape can effectively cause the incoming desert wind to swirl and rise, while the conical top 31 can reduce the wind load on the top of the support 3, further weakening the impact of strong winds. In specific application scenarios, the torsion rate of the streamlined torsion body 33 is preferably in the range of 5 to 15° / m, and the cone angle of the top 31 is preferably in the range of 15 to 60°.

[0037] In some more specific embodiments, the photovoltaic guardrail assembly 1 further includes: a first connector 7, a second connector 32, a third connector 34, a fourth connector 35, and a fifth connector 36. The first connector 7 is disposed between the sand barrier 6 and the plurality of double-sided photovoltaic panels 4, and connects the sand barrier 6 and the plurality of double-sided photovoltaic panels 4 respectively. The second connector 32 is disposed on one side of the double-sided photovoltaic panel 4, and connects the bracket 3 and the double-sided photovoltaic panel 4 respectively. The third connector 34 is disposed on one side of the sand barrier 6, and connects the bracket 3 and the sand barrier 6 respectively. The fourth connector 35 is disposed above the double-sided photovoltaic panel 4, and connects two brackets 3 respectively. The fifth connector 36 is disposed above the double-sided photovoltaic panel 4, and connects two adjacent double-sided photovoltaic panels 4 respectively.

[0038] In this embodiment, the first connector 7 is used to connect the sand barrier 6 and multiple double-sided photovoltaic panels 4, preventing breakage between the sand barrier 6 and the multiple double-sided photovoltaic panels 4 and strengthening the ability of the photovoltaic guardrail assembly 1 to block wind and sand; the second connector 32 is used to connect the bracket 3 and the double-sided photovoltaic panels 4, reinforcing the double-sided photovoltaic panels 4 by connecting the bracket 3 on both sides of the multiple double-sided photovoltaic panels 4; the third connector 34 is used to connect the bracket 3 and the sand barrier 6, reinforcing the sand barrier 6 by connecting the bracket 3 on both sides of the sand barrier 6; the fourth connector 35 is connected above the double-sided photovoltaic panels 4, covering the multiple double-sided photovoltaic panels 4, further reinforcing the multiple double-sided photovoltaic panels 4; the fifth connector 36 is used to connect two adjacent double-sided photovoltaic panels 4, further reinforcing the connection between the multiple double-sided photovoltaic panels 4.

[0039] Specifically, the second connector 32 and the third connector 34 are both aluminum alloy clamps, which make the connection between the bracket 3 and the sand barrier 6 and the double-sided photovoltaic panel 4 more secure. The fourth connector 35 is an aluminum alloy rod that connects the two brackets 3 laterally. More specifically, multiple fifth connectors 36 are connected to the side of the fourth connector 35 near the multiple double-sided photovoltaic panels 4. Together with the aluminum alloy rod, they make the multiple double-sided photovoltaic panels 4 more stable, improving the overall wind and sand blocking effect of the photovoltaic guardrail assembly 1.

[0040] Combination Figure 2 As shown, in some embodiments, the sand barrier 6 is a nylon mesh, and the permeability of the sand barrier 6 near the ground is higher than that of the end away from the ground.

[0041] In this embodiment, nylon mesh is a commonly used device in photovoltaic power plants. The permeability of the sand barrier 6 near the ground is higher than that of the end away from the ground. The permeability of the nylon mesh is the area ratio; the higher the permeability, the denser the mesh and the thinner the nylon rope; the lower the permeability, the sparser the mesh and the thicker the nylon rope. That is, the nylon rope at the bottom of the sand barrier 6 is denser, which improves the blocking effect of the sand barrier 6 on sand and gravel near the ground. Specifically, the permeability of the sand barrier 6 near the ground is preferably in the range of 55% to 65%, and the permeability of the sand barrier 6 away from the ground is preferably in the range of 40% to 50%.

[0042] In practical applications, when easterly or westerly winds pass over the perimeter fencing of a desert photovoltaic power station, most of the near-ground dust movement is concentrated within a 0.5-meter range. The preferred value for the height H2 of the sand barrier 6 is 0.5 to 1.0 meters, which can significantly limit the range of wind and sand movement within a 0.5 to 1-meter range.

[0043] Combination Figure 1As shown, in some embodiments, the minimum horizontal distance W between the outer guardrail device and the inner photovoltaic device is W = Hcosγ / tanα; where H is the superposition height of the sand barrier 6 and the double-sided photovoltaic panel 4, γ is the solar azimuth angle, and α is the solar altitude angle.

[0044] In this embodiment, the minimum horizontal distance W between the outer guardrail device and the inner photovoltaic device is set according to the solar azimuth angle γ, the solar altitude angle α, and the superposition height H of the sand barrier 6 and the double-sided photovoltaic panel 4. This can prevent the outer guardrail device from blocking the inner photovoltaic device and maximize the protection of the inner photovoltaic device from the effects of wind and sand.

[0045] Combination Figure 1 As shown, in some embodiments, the misalignment distance w2 between two adjacent columns of photovoltaic guardrail components 1 is 1 / 2(L+w1); where L is the length of the photovoltaic guardrail component 1 and w1 is the spacing between two adjacent photovoltaic guardrail components 1 in one column.

[0046] In this embodiment, the staggered distance w2 between two adjacent columns of photovoltaic guardrail components 1 is set according to the length L of the photovoltaic guardrail component 1 and the distance w1 between two adjacent photovoltaic guardrail components 1, so as to maximize the wind and sand prevention effect of the outer guardrail device.

[0047] Specifically, the length L of the photovoltaic guardrail component 1 is L = n * Lp, where n is the number of double-sided photovoltaic panels 4, and Lp is the width of one of the double-sided photovoltaic panels 4. Multiple double-sided photovoltaic panels 4 are attached together in sequence.

[0048] Combination Figure 4 As shown, in practical application scenarios, windbreak plants are planted on the ground 9 inside the outer guardrail device, that is, between two adjacent photovoltaic guardrail components 1. The windbreak plants can effectively prevent sand and stabilize the soil.

[0049] Combination Figure 1 and Figure 4 As shown, in some embodiments, the wind and sand protection photovoltaic power station also includes an automatic water collection and soil stabilization device, which includes a water reservoir 5 and a water tank 11; the water reservoir 5 is located between the sand barrier 6 and the double-sided photovoltaic panel 4, and the bottom of the water reservoir 5 is provided with a water outlet 8; the water tank 11 is located between two adjacent rows of photovoltaic guardrail components 1, and the top of the water tank 11 is connected to the water outlet 8 through a hose 10, and the water tank 11 is provided with multiple water outlet holes 12.

[0050] In this embodiment, due to the large temperature difference between day and night and the high humidity at night in the desert environment, water vapor in the air easily condenses into liquid on the surface of the double-sided photovoltaic panel 4 and slides down to the ground below. Simultaneously, rainfall fully contacts the surface of the double-sided photovoltaic panel 4 and also slides along its surface. A water storage tank 5 is positioned between the sand barrier 6 and the double-sided photovoltaic panel 4, facilitating water to slide down the double-sided photovoltaic panel 4 into the water storage tank 5, thereby automatically collecting water from the desert. The top of the water storage tank 11 is connected to the outlet 8 of the water storage tank 5 via a flexible hose 10, used to store the water collected from the water storage tank 5. The water storage tank 11 is positioned between two adjacent rows of photovoltaic guardrail components 1 and has multiple water outlets 12 for irrigating the windbreak plants planted between the two adjacent photovoltaic guardrail components 1, resulting in a better sand control effect for the entire photovoltaic power station, thus achieving automatic water collection and soil stabilization and photovoltaic ecological desertification control. Specifically, the water storage tank 11 is positioned below the sand to irrigate the interior of the sand, thereby achieving the solidification effect on the sand. More specifically, the water tank 11 is made of stainless steel, which allows it to be used for a long time in the desert without frequent replacement or maintenance.

[0051] Combination Figure 2 As shown, in practical applications, the height H1 of the double-sided photovoltaic panel 4 and the height H2 of the sand barrier 6 are as follows: the preferred value range for the height H1 of the double-sided photovoltaic panel 4 is 2–2.5 meters, and the preferred value range for the height H2 of the sand barrier 6 is 0.5–1.0 meters. Since a water reservoir 5 is installed between the sand barrier 6 and the double-sided photovoltaic panel 4, the combined height H of the sand barrier 6 and the double-sided photovoltaic panel 4 is approximately 2.6–3.6 meters, based on the height of the water reservoir 5. More specifically, the height H of the support bracket 3... S It is higher than H, and the elevation ranges from 0.1 to 0.3 meters.

[0052] In some specific embodiments, the automatic water collection and soil stabilization device further includes: an inlet trough 51, a filter plate 52, and a multi-layer water-absorbing foam 13; the inlet trough 51 is attached to the double-sided photovoltaic panel 4 and connected to the water storage device 5; the filter plate 52 is laid above the water outlet 8; and the multi-layer water-absorbing foam 13 is disposed between the water storage tank 11 and the hose 10.

[0053] In this embodiment, the inlet groove 51 is attached to the double-sided photovoltaic panel 4 to facilitate the collection of condensate and rainwater from the surface of the double-sided photovoltaic panel 4. The filter plate 52 is used to filter impurities in the water to prevent the water reservoir 5 from clogging. The multi-layer water-absorbing foam 13 is used to absorb the water collected in the water reservoir 5 through the hose, so that the water in the water reservoir 5 automatically flows into the water storage tank 11. Specifically, the filter plate 52 includes high-precision PP cotton 521 and filter paper 522. The filter paper 522 is laid above the water outlet 8, and the high-precision PP cotton 521 is laid above the filter paper 522. They are used to filter impurities, pests, bacteria, and heavy metals, respectively, which helps to protect the growth of windbreak plants.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
