Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation technology, specifically a double-slot arrangement bracket for solar photovoltaic modules used in photovoltaic agriculture. Background Technology

[0002] Photovoltaic agriculture is a new industrial model that combines solar photovoltaic power generation with agricultural production. Without changing the nature of agricultural land use, it achieves rooftop power generation and underground planting and breeding by installing photovoltaic panels on or around agricultural facilities such as greenhouses, orchards, and fish ponds. This model can provide crops with suitable light and temperature control environment, and can also generate electricity for grid connection and self-consumption. It is a win-win path to solve the problem of land competition for photovoltaic power generation and promote the transformation of green agriculture.

[0003] In photovoltaic agriculture, solar photovoltaic modules typically employ high-efficiency crystalline silicon modules with bifacial or half-cell technology, which can maintain power generation efficiency in agricultural environments characterized by low light, high humidity, and dust. Their surfaces often use dustproof and self-cleaning anti-reflective coated glass to reduce the impact of pesticide and dust adhesion on light transmittance. The support structures that support these modules need to balance power generation efficiency with agronomic requirements. Common types include fixed, single-axis, or dual-axis tracking supports. In agricultural settings, elevated, large-span structures are also used to facilitate the passage of agricultural machinery and crop growth. The support materials are mostly hot-dip galvanized steel or aluminum alloy, and require corrosion-resistant treatment. The foundations are selected based on the soil conditions, using either independent concrete foundations or helical piles.

[0004] A Chinese patent with publication number CN224319282U discloses a double-gap arrangement support for solar photovoltaic modules based on photovoltaic agriculture, including solar photovoltaic modules, purlins, secondary beams, support columns, main longitudinal beams of the frame, and uprights; the solar photovoltaic modules are arranged in an aligned horizontal arrangement, a staggered horizontal arrangement, an aligned vertical arrangement, or a staggered vertical arrangement; horizontal and vertical gaps are provided between the long and short side frames of adjacent solar photovoltaic modules, and the purlins are arranged horizontally and vertically at intervals to directly support the solar photovoltaic modules.

[0005] When building photovoltaic agriculture systems to generate electricity using solar photovoltaic modules and achieve agricultural-solar complementarity, existing arrangements of solar photovoltaic modules, such as single rows or closely spaced straight rows, while absorbing sunlight, can easily affect the growth of crops below. The aforementioned solar photovoltaic modules, through the use of double-slit arrangement brackets to optimize the arrangement, employ a special arrangement with double slits set horizontally and vertically between adjacent solar photovoltaic modules, improving the uniform distribution of light and light utilization. However, it is difficult to dynamically adjust according to the intensity of light. When light conditions change significantly, such as during periods of relatively low light intensity in the morning or afternoon, or during alternating cloudy and sunny days, the aforementioned double-slit arrangement brackets cannot adapt to these changes. This means that strong light may still damage crops, and when the light is too intense, crops may suffer from scorching from the strong sunlight, thus affecting their growth.

[0018] The beneficial effects of this invention are as follows: 1. The present invention relates to a double-slit arrangement support for solar photovoltaic modules used in photovoltaic agriculture. In photovoltaic agriculture, traditional single-row or densely connected photovoltaic modules easily shade crops. The double-slit arrangement support ensures uniform light exposure through the longitudinal and transverse slits between the modules. This support, based on a double-slit design, consists of a support base, a rotating frame, a top frame, and an adjustment mechanism. It is equipped with a photovoltaic backsheet and a bottom dimming component, and can be dynamically adjusted. For example, in the morning when the light is weak, the dimming component is retracted, and the component is upright or rotated to reduce shading, creating a linear shadow to supplement the light with gentle sunlight. In the midday when the light is strong, the component is unfolded to provide shade. The light-blocking components extend to fill gaps in crops, filtering strong light and preventing scorching. On cloudy days and at night, the components retract vertically, fully retracting to increase the reception of diffused light and ensure photosynthesis. On rainy days, they extend to provide shade when irrigation is not needed, reducing water damage. When irrigation is required, they retract to allow rainwater to directly irrigate the fields. By dynamically adjusting the width of the double gaps, the shading area, and the light transmittance, the system adapts to changes in light intensity and water demand, balancing power generation efficiency and crop growth to achieve stable operation of agricultural-solar complementary systems. Multiple toothed plates can be connected and linked, and optional light monitoring equipment or manual control can be used.

[0019] 2. The photovoltaic agricultural solar photovoltaic module double-slit arrangement support described in this invention, when filling the double-slit dimming gap, the bottom of each photovoltaic back panel is driven by a first electric slider to move a square slider, so that the frosted diffuser plate supported by the sliding frame and the thin micro-prism light guide strip fixed at intervals extend out. After adjacent dimming modules are spliced, the diffuser plate and the light guide strip together fill the light transmission gap, allowing some light to pass through while dispersing strong direct light into uniform diffuse light, avoiding local scorching of crops; at the same time, the micro-prism refracts and guides light to other areas and the middle and lower leaves, ensuring the photosynthetic efficiency of the lower layer and reducing yellowing due to lack of light. When it is necessary to reduce shading, the electric slider drives the square slider to retract to the bottom of the back panel, completely storing the dimming module, without affecting the diffused light passing through the double slits to reach the field.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 9As shown in the embodiment of the present invention, a double-slot arrangement support for photovoltaic agricultural solar photovoltaic modules includes a support base 1; a rotating frame 13 is rotatably connected to the top of the support base 1; a top frame 14 is fixedly connected to the top of the rotating frame 13; a gear 11 is fixedly connected to the outside of the bottom end of the rotating frame 13; a rack plate 12 is slidably connected to the support base 1 near the gear 11; two photovoltaic backsheets 15 are arranged on one side of the top frame 14; an adjustment mechanism is provided on the top frame 14 for adjusting the angle and position of the two photovoltaic backsheets 15; a dimming unit is provided at the bottom of the photovoltaic backsheets 15. Dimming components are used to modulate the intensity of sunlight. In photovoltaic agriculture, when building solar photovoltaic modules for power generation and agricultural photovoltaic complementarity, traditional arrangements of solar photovoltaic modules, such as single-row or closely spaced vertical arrangements, while absorbing sunlight, can easily affect the growth of crops below. Existing solar photovoltaic modules optimize the arrangement by using a double-slit mounting bracket. This special arrangement uses double slits both horizontally and vertically between adjacent solar photovoltaic modules, enabling aligned horizontal, staggered horizontal, aligned vertical, and staggered vertical arrangements. Furthermore, horizontal and vertical slits are provided between the four sides of the frames of adjacent solar photovoltaic modules. The gaps in the solar panels ensure uniform light distribution and efficient light utilization. This agricultural solar photovoltaic module double-gap arrangement support is built using a double-gap arrangement, fixed to the ground by a support base 1. A rotating frame 13 and a top frame 14 are located above the support base 1. The rotating frame 13 and top frame 14, along with an adjustment mechanism, mount two photovoltaic backsheets 15. Solar photovoltaic modules are installed on the photovoltaic backsheets 15 for power generation. Dimming components are mounted at the bottom of the photovoltaic backsheets 15. Two sets of dimming components fill the gaps between adjacent solar photovoltaic modules. Through the cooperation of the dimming components and the solar photovoltaic modules, the system can generate electricity. It can protect the crops below according to different light intensities. For example, on a hot and sunny day, when the light is mild in the morning, the dimming component is retracted into the bottom of the photovoltaic back panel 15 for storage. The adjustment mechanism adjusts the solar photovoltaic component to keep it vertical. By pulling or pushing the rack plate 12, it slides on the bracket 1. The rack plate 12 can drive the gear 11 to mesh and rotate, which simultaneously drives the solar photovoltaic component mounted above to rotate left and right, reducing the shading of the light. The shading of the solar photovoltaic component forms a line. At this time, the crops are unshaded and receive mild light for supplemental lighting. When the midday sunlight intensity continues to rise and is likely to scorch crops, the adjustment mechanism drives the photovoltaic module to rotate, shielding the crops from the photovoltaic module. At the same time, the dimming module extends from the bottom of the photovoltaic back panel 15, and the two connected dimming modules fill the double gap to reduce the strong light exposure. The dimming module filters out some of the excessive light, improves the light transmittance, and keeps the light intensity reaching the crops within a suitable range, thus avoiding strong light scorching the crop tissue. When it gets dark or there is insufficient sunlight, the dimming components are completely retracted and stored. At the same time, the adjustment mechanism adjusts the photovoltaic components to be vertical, reducing the shading area and allowing as much diffused light as possible to reach the crops below, ensuring the light conditions required for crop photosynthesis. Meanwhile, when it rains, the photovoltaic modules can be deployed or retracted according to the rainwater demand. When irrigation is not needed, the adjustment mechanism drives the photovoltaic modules to deploy, and the dimming modules also deploy, which can shield the rainwater and reduce the impact of rainwater on tender crops and the humid environment. When irrigation is needed, the photovoltaic modules and dimming modules are retracted, allowing rainwater to irrigate the fields normally and meet the water supply needs of crops. By dynamically adjusting to adapt to different time periods and weather conditions, the width of the double slits, the shading area, and the light transmittance can be dynamically adjusted to maintain the light and water conditions of the crops below within a suitable range. This not only retains the advantages of the double slit arrangement in ensuring uniform light and utilization, but also solves the problem that traditional fixed double slit supports are difficult to adapt to changes in light intensity. It takes into account both photovoltaic power generation efficiency and crop growth needs, and achieves stable operation of agricultural-photovoltaic complementarity. It should be noted that if multiple rack plates 12 are to be pulled and slid simultaneously, they need to be connected in advance. This will enable the sliding of multiple rack plates 12 when one rack plate 12 is pulled. During adjustment, a light monitoring device can be selected to monitor the light in real time according to the monitoring conditions of the site environment. If there is manual monitoring, there is no need to install a light monitoring device.

[0025] The dimming assembly includes a sliding frame 4, a frosted diffuser plate 41, microprism light guide strips 42, and a square slider 43. The square slider 43 is slidably connected to the bottom of the photovoltaic backsheet 15 via a first electric slider. The sliding frame 4 is fixed to the bottom of the square slider 43. The frosted diffuser plate 41 is fixed to the inner wall of the sliding frame 4. Multiple microprism light guide strips 42 are fixed to the upper surface of the frosted diffuser plate 41, and the multiple microprism light guide strips 42 are spaced apart. When dimming the gap between two sets of photovoltaic modules, a square slider 43 slides at the bottom of each photovoltaic backsheet 15 via a first electric slider. The sliding frame 4 is installed at the bottom of the square slider 43 for support. As the frosted diffuser plate 41 is fixed to the bottom of the sliding frame 4, the microprism light guide strips 42 are thin and multiple microprism light guide strips 42 are fixed at intervals on the frosted diffuser plate 41. When the dimming assembly moves from the photovoltaic backsheet 15... After the bottom extends, the dimming components of two adjacent photovoltaic back panels 15 are spliced ​​together close to each other. The frosted diffuser plate 41 and the spaced microprism light guide strips 42 will fill the light transmission gap of the double slits. This allows some light to pass through while dispersing excessively strong direct light into uniform diffused light, reducing the local high temperature burn caused by strong light on the surface of crops. At the same time, the microprism light guide strips 42 can also refract and guide some light, allowing more light to illuminate other areas. Some light can also illuminate the middle and lower leaves of crops, ensuring the photosynthetic efficiency of the lower leaves and preventing the leaves from yellowing due to lack of light, which would affect crop growth. When it is necessary to reduce the shading area, the first electric slider drives the square slider 43 to retract to the bottom of the photovoltaic back panel 15, storing the entire dimming component under the photovoltaic back panel 15 without blocking excess light, ensuring that diffused light can pass through the double slits to reach the field normally.

[0026] A fixing rod 5 is fixed inside the photovoltaic backsheet 15 near the square slider 43, and the fixing rod 5 passes through the center of the square slider 43. A first elastic element 51 is sleeved on the fixing rod 5, and the first elastic element 51 is located between the inner wall of the photovoltaic backsheet 15 and the outer wall of the square slider 43. A sliding groove 52 is formed on the upper surface of the square slider 43. A limiting plate 53 is slidably connected inside the photovoltaic backsheet 15. The limiting plate 53 is located above the square slider 43. The limiting plate 53 is composed of a large square plate and multiple small square plates. The multiple small square plates are fixed to the bottom of the large square plate, and both sides of the small square plates are set as arc surfaces. A second elastic element 54 is fixed inside the fixing rod 5 and above the limiting plate 53. When the position range of the sliding frame 4 is limited, the limiting plate 53 is pressed by the second elastic element 54 to the bottom of the photovoltaic backsheet 15, so that part of the small square plates at the bottom of the large square plate of the limiting plate 53 are inserted. The sliding groove 52 on the upper surface of the square slider 43 is opened in the length of the sliding groove 52, which is one section of the dimming component's sliding. When the sliding frame 4 is stored at the bottom of the photovoltaic backsheet 15, the first electric slider drives the square slider 43 to slide on the fixed rod 5, and the square slider 43 presses the first elastic element 51 to contract and be stressed. The small square plate at the bottom of the limiting plate 53 slides in the sliding groove 52. If it is necessary to adjust to the next section, the first electric slider continues to drive the square slider 43 to slide. The square slider 43 presses the arc surface of the limiting plate 53. After the square slider 43 passes the limiting plate 53, it reaches the next limiting plate 53, that is, it enters the next section. The second elastic element 54 pushes the limiting plate 53 down again, so that the small square plate in the new position inserts into the corresponding sliding groove 52, completing the locking of the sliding position. This prevents the dimming component from sliding and shifting its position at will when the bracket shakes, ensuring the stability of the position of the dimming component after it extends or retracts, and maintaining the stability of the light transmittance.

[0027] like Figures 1 to 5 As shown, the adjustment mechanism includes a rotating roller 2, a connecting plate 21, a servo motor 22, and an adjustment component. The rotating roller 2 is rotatably connected to the center of the top frame 14. The connecting plate 21 is fixed to the outside of the rotating roller 2. The servo motor 22 is fixed to one side of the top frame 14, and the output end of the servo motor 22 is connected to one end of the rotating roller 2. The adjustment component is set on the connecting plate 21 and is used to adjust the position of the two photovoltaic backsheets 15. When adjusting the light-receiving angle of the solar photovoltaic module, the servo motor 22 is installed at one end of the top frame 14. The output end of the servo motor 22 rotates, driving the rotating roller 2 to rotate synchronously. The two photovoltaic backsheets 15 mounted on the connecting plate 21 through the adjustment component rotate synchronously, thereby driving the installed photovoltaic module to adjust its angle to match the solar altitude angle at different times, ensuring the overall solar capture efficiency and photovoltaic power generation of the photovoltaic module. At the same time, it coordinates with the angle rotation of the photovoltaic module to adjust the shading area below, realizing the synchronous adjustment of light-receiving power generation and crop shading.

[0028] The adjustment assembly includes a double-threaded rod 3 and sliding blocks 31. The double-threaded rod 3 is rotatably connected to the connecting plate 21, and has two opposite threads. The two sliding blocks 31 are threadedly connected to both sides of the double-threaded rod 3, and are slidably connected to the inner wall of the connecting plate 21. The photovoltaic backsheet 15 is fixed to one end of the connecting plate 21. When adjusting the distance between the two photovoltaic backsheets 15 to accommodate photovoltaic modules of different specifications, the double-threaded rod 3 is manually rotated in the forward direction. The two sliding blocks 31 engage with the threads on the double-threaded rod 3, bringing the two photovoltaic backsheets 15 connected to the two sliding blocks 31 closer together. This accommodates the installation requirements of photovoltaic modules with smaller widths and expands the spacing between the two gaps. If a wider photovoltaic module is required, rotating the double threaded rod 3 in the reverse direction will cause the two sliding blocks 31 to move away from each other, widening the gap between the two photovoltaic backplates 15. This allows for the installation of larger photovoltaic modules and meets the requirements for double-gap settings with different layout spacings. This ensures the adaptability of the bracket to different photovoltaic agricultural site layouts, eliminating the need to customize brackets to the corresponding specifications based on the photovoltaic module size. Furthermore, a single photovoltaic module can be mounted on both photovoltaic backplates 15, or a single photovoltaic module can be mounted on each of the two photovoltaic backplates 15. The mounting method can be flexibly selected according to actual installation needs, adapting to the differentiated requirements of photovoltaic power generation and shading requirements of different agricultural-photovoltaic complementary sites, thus broadening the adaptability range.

[0029] like Figures 1 to 9As shown, a first water channel 6 is formed inside the photovoltaic back panel 15; a water storage valve 61 is fixedly connected to the bottom end of the photovoltaic back panel 15, and the water storage valve 61 is connected to the bottom end of the first water channel 6; multiple first water outlets 62 are formed at the bottom end of the photovoltaic back panel 15; a first fixing block 63 and a second fixing block 64 are fixedly connected to the upper surface of the photovoltaic back panel 15, and the first fixing block 63 and the second fixing block 64 are close to the water inlet of the first water channel 6, and the first fixing block 63 and the second fixing block 64 are arranged opposite to each other; when it rains, the photovoltaic panel is installed on the photovoltaic back panel 15, and the photovoltaic panel is located between the first fixing block 63, the second fixing block 64 and the inner wall of the photovoltaic back panel 15, the water inlet of the first water channel 6 is exposed, and the first fixing block 63 and the second fixing block 64 are connected to the inner wall of the photovoltaic back panel 15. The second fixing block 64 not only limits the installation of the photovoltaic panel, but also guides rainwater into the interior of the first water channel 6. With the photovoltaic panel covering the crops, rainwater flows along the tilt of the photovoltaic panel into the interior of the first water channel 6. At this time, the water storage valve 61 is closed, and the rainwater is stored inside the first water channel 6. The rainwater drips down through multiple first water outlets 62, slowly irrigating the root area of ​​the crops. This can prevent waterlogging in the field caused by short-term heavy rainfall, maintain soil moisture after the rainfall, extend the water supply time, and reduce the frequency of artificial irrigation. If the water storage reaches the storage limit and rainfall continues, the valve of the water storage valve 61 can be opened to discharge the excess rainwater from the entire support structure, preventing water overflow and causing excessive weight of the photovoltaic back panel 15, which would result in structural overload.

[0030] The frosted diffuser plate 41 has multiple secondary water flow holes 7, which are located between multiple microprism light guide strips 42. The upper surface of the sliding frame 4, located at one end of the microprism light guide strip 42, has a secondary water guide groove 71. When drip irrigation is applied to the crops at the bottom from the frosted diffuser plate 41 during rainy weather, the rainwater falls on the frosted diffuser plate 41 and flows towards the secondary water guide groove 71. Some of the rainwater drips down to the crops through the multiple secondary water flow holes 7, allowing some rainwater to be directly supplied to the field through the dimming component. The remaining rainwater flows along the inclined surface of the frosted diffuser plate 41 to the secondary water guide groove 71 at the end. The bottom of the secondary water guide groove 71 can be filled with ditches to store water, or a water storage tank can be added at the outlet of the secondary water guide groove 71. This allows for both immediate use and excess storage of rainwater, ensuring the utilization rate of rainwater resources.

[0031] Multiple partition plates 8 are fixed to the upper surface of the frosted diffuser plate 41. The partition plates 8 are located between multiple microprism light guide strips 42, and the end of the partition plate 8 away from the second water guide trough 71 is set as a slope. When rainwater flows along the inclined surface of the frosted diffuser plate 41 to the second water guide trough 71 at the end, some rainwater is intercepted by the multiple partition plates 8 and multiple microprism light guide strips 42, so that some rainwater can be temporarily stored in the long groove formed by two partition plates 8 and two microprism light guide strips 42. The rainwater drips through multiple second water outlets 7 to irrigate the crops at the bottom, avoiding all the rainwater from flowing away quickly and being difficult to utilize, thus prolonging the duration of rainwater drip irrigation. Excess rainwater can flow away along the slope of the partition plate 8, reducing additional irrigation input.

[0032] like Figures 1 to 4 As shown, a solar position sensor 9 is fixedly connected to the upper surface of the top frame 14, and the solar position sensor 9 is electrically connected to the servo motor 22; a wind speed and direction sensor 91 is fixedly connected to the upper surface of the top frame 14 and the end away from the solar position sensor 9; the solar position sensor 9 monitors the solar azimuth angle and light intensity in real time. When it detects a change in light intensity or solar azimuth, it can automatically send an adjustment signal to the servo motor 22, which drives the rotating roller 2 to rotate the connecting plate 21, automatically completing the adjustment of the photovoltaic module angle without manual adjustment, thus realizing the dynamic adaptation of the bracket; Meanwhile, the wind speed and direction sensor 91 can monitor the wind force and direction in the field in real time. When the wind force is too strong and diversion is required, the wind speed and direction sensor 91 sends an adjustment signal, and the servo motor 22 can drive the photovoltaic module to adjust the angle to divert the wind. If the wind speed and direction sensor 91 detects that the wind force exceeds the safety threshold that the support structure can withstand, it can send an alarm to the staff and manually adjust the photovoltaic module to rotate to a vertical position with the wind direction to reduce the wind resistance area, reduce the impact of strong wind on the photovoltaic module and support structure, avoid damage to the support by strong wind, and ensure the support's risk resistance capability under extreme weather conditions.

[0033] like Figures 1 to 9 As shown, the diameter of the first water outlet 62 is larger than that of the second water outlet 7; the number of holes in the second water outlet 7 is greater than that in the first water outlet 62. When drip irrigation is applied to the bottom crops during rainy weather, the larger diameter first water outlet 62 relies on the rainwater stored in the first water channel 6 to achieve continuous and stable high-flow drip irrigation, replenishing the deep soil moisture in the root zone of the crops; while the smaller diameter and more numerous second water outlets 7 rely on the rainwater collected by the dimming component to achieve low-flow uniform drip irrigation, soaking the surface soil around the crops, forming a layered water replenishment effect, which can simultaneously meet the needs of surface moisture retention and deep water replenishment, ensuring the efficiency of rainwater resource utilization and adapting to the water needs of crops at different growth stages.
