Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a wind-resistant flexible photovoltaic bracket. Background Art

[0002] As an indispensable key component of photovoltaic power stations, wind-resistant flexible photovoltaic brackets play a vital role. This bracket must not only be able to withstand the pressure and impact of natural environmental factors such as strong winds and snowstorms, but also must ensure the stable installation and long-term stable operation of photovoltaic panels. In addition, the design and material selection of wind-resistant flexible photovoltaic brackets must take into account improving the power generation efficiency of the entire photovoltaic system to ensure that efficient energy conversion and output can be maintained under various climatic conditions.

[0003] However, existing wind-resistant flexible photovoltaic brackets have limitations in design. For example, it is often difficult to balance the wind resistance and flexibility of the bracket, resulting in the photovoltaic panels not being able to maintain the best working condition or even being damaged under extreme weather conditions.

[0060] Photovoltaic support body 100;

[0061] A fixing assembly is located at the bottom of the photovoltaic support body 100. The fixing assembly includes a fixing plate 111 and a fixing anchor 112. The fixing plate 111 is located at the bottom of the photovoltaic support body 100. The fixing anchor 112 is connected to the bottom end of the fixing plate 111.

[0065] The control assembly 150 is connected to the support assembly and the photovoltaic assembly.

[0066] It can be understood that the photovoltaic bracket body 100 is made of corrosion-resistant, high-strength materials to ensure stability and durability under various climatic conditions; the fixing plate 111 has sufficient area and weight to ensure the stability of the photovoltaic bracket body 100 under strong wind conditions; the fixing anchor 112 is made of high-strength materials, such as stainless steel or hot-dip galvanized steel, to prevent rust and provide long-term fixing effect. The shape and size of the fixing anchor 112 are optimized according to the ground type and soil conditions to ensure good fixing effect under different geological conditions; the support component adopts an adjustable height design, so that the photovoltaic panel 132 can adjust the tilt angle according to seasonal changes and geographical location to obtain optimal lighting conditions; the rotating connection design of the support component allows the photovoltaic component to have a certain swing space under the action of wind, so as to The direct impact of wind on the photovoltaic panel 132 is reduced; the shock absorbing component is set to further reduce the impact of wind on the photovoltaic panel 132. The combination of shock absorbing springs and shock absorbing pads can absorb and disperse the vibration caused by wind and protect the photovoltaic panel 132 from damage; the control component 150 is the core part of the present invention. It realizes intelligent control of the inclination angle of the photovoltaic panel 132 through the coordinated work of the acquisition module 151, the judgment module 152, the adjustment module 153 and the storage module 154; the acquisition module 151 can monitor the light and wind speed data in real time, the judgment module 152 determines whether the inclination angle of the photovoltaic panel 132 needs to be adjusted based on these data, and the adjustment module 153 makes precise adjustments based on the judgment results and historical data; the storage module 154 is used to process and store relevant data to provide a reference for future adjustments.

[0067] It is understandable that the wind-resistant flexible photovoltaic bracket provided in this embodiment can effectively reduce the impact of wind on the photovoltaic panel 132, and improve the overall stability and power generation efficiency of the photovoltaic power station. Compared with the traditional rigid photovoltaic bracket, the photovoltaic bracket provided in this embodiment has better adaptability and flexibility, can adapt to a variety of complex environmental conditions, and provides reliable guarantee for the long-term stable operation of the photovoltaic power station.

[0068] Specifically, the support components include:

[0069] There are four lifting rods 121, which are arranged on the top of the fixing plate 111 in the vertical direction and at the four corners of the fixing plate 111. The bottom ends of the lifting rods 121 are connected to the fixing plate 111, and the top ends of the lifting rods 121 are connected to the photovoltaic module. The lifting rods 121 include a fixed section 1121 and a lifting section 1212. The fixed section 1121 is located on a side close to the fixing plate 111, and the lifting section 1212 is arranged on a side close to the photovoltaic module.

[0070] The driving motor is arranged on the fixing plate 111 , and the output end of the driving motor is connected to the lifting rod 121 . The driving motor is used to drive the lifting rod 121 to perform lifting motion.

[0071] It can be understood that the design of the lifting rod 121 allows the photovoltaic bracket body 100 to be precisely adjusted at different heights to adapt to different installation environments and lighting conditions; the adjustability of the lifting section 1212 enables the photovoltaic panel 132 to be tilted according to actual needs to achieve the optimal light receiving angle; the use of the drive motor ensures that the lifting movement of the lifting rod 121 can be completed quickly and accurately, thereby improving the response speed and adjustment efficiency of the photovoltaic bracket.

[0072] Specifically, photovoltaic modules include:

[0073] A rectangular frame 131 is rotatably connected to the top of the lifting rod 121;

[0074] The photovoltaic panel 132 is located inside the rectangular frame 131 , and the photovoltaic panel 132 matches the rectangular frame 131 .

[0075] It is understandable that the design of the rectangular frame 131 provides a stable support structure for the photovoltaic panel 132, ensuring the stability and safety of the photovoltaic panel 132 under various weather conditions; the size and shape of the rectangular frame 131 can be customized according to actual needs to accommodate photovoltaic panels 132 of different sizes and shapes; the material of the rectangular frame 131 is selected to be lightweight and high-strength, such as aluminum alloy or carbon fiber, to reduce the overall weight while maintaining sufficient structural strength. The photovoltaic panel 132 is composed of a plurality of photovoltaic cell units, which are connected in series or in parallel to achieve the required voltage and current output. The surface of the photovoltaic panel 132 is covered with an anti-reflective coating to reduce the reflection loss of sunlight and improve the photoelectric conversion efficiency. The back of the photovoltaic panel 132 is provided with a heat dissipation structure, such as a heat sink or a heat dissipation channel, to effectively dissipate the heat generated by the photovoltaic panel 132 during operation, to ensure the stable operation of the photovoltaic panel 132 and to extend the service life.

[0076] Specifically, the shock absorbing components include:

[0077] There are a plurality of shock absorbing springs, and the plurality of shock absorbing springs are evenly arranged between the photovoltaic panel 132 and the rectangular frame 131;

[0078] Dampers are located at both ends of the shock absorbing spring;

[0079] A shock absorbing pad is arranged between the shock absorbing spring and the damper.

[0080] It can be seen that the shock-absorbing spring can effectively absorb and disperse the vibration caused by the wind, thereby protecting the photovoltaic panel 132 from damage; the damper is a suppressor of breeze resonance, which can reduce the vibration amplitude of the shock-absorbing spring and improve the stability of the system; the shock-absorbing pad further absorbs the remaining vibration energy to ensure that the photovoltaic panel 132 can remain stable even under extreme weather conditions. This combined design of the shock-absorbing components not only improves the wind resistance of the photovoltaic bracket, but also extends the service life of the photovoltaic panel 132.

[0081] Specifically, the connecting cable 140 includes:

[0082] A prestressed cable is arranged on one side of the support assembly close to the fixed plate 111, one end of the prestressed cable is connected to the fixed section 1121, and the other end of the prestressed cable is connected to the fixed plate 111;

[0083] A prestressed cable is a cable that improves the stability and load-bearing capacity of a structure by applying a certain tension in advance. In this embodiment, the use of the prestressed cable 140 can effectively resist the lateral thrust of the wind on the photovoltaic support body 100, thereby enhancing the wind resistance of the entire photovoltaic support. The tension of the prestressed cable 140 can be adjusted according to the actual wind force and the installation environment of the photovoltaic support to ensure that the photovoltaic support can be kept stable under various climatic conditions.

[0084] Specifically, the control component 150 includes:

[0085] The acquisition module 151 is configured to establish a monitoring area with the center of mass of the fixed plate 111 as the center of the circle and R as the radius, collect the illumination data of the monitoring area, and determine the initial tilt angle of the photovoltaic panel 132 according to the illumination data; wherein the initial tilt angle is the angle between the normal line of the photovoltaic panel 132 and the fixed plate 111;

[0086] The judgment module 152 is configured to control the collection module 151 to collect wind speed data in the monitoring area, and judge whether to adjust the initial tilt angle according to the wind speed data;

[0087] The adjustment module 153 is configured to compare the wind speed data with the historical data when the judgment module 152 determines to adjust the initial tilt angle, and adjust the initial tilt angle according to the comparison result;

[0088] The adjustment module 153 is further configured to calculate a correlation index between the wind speed data and the historical data when there is no historical wind speed data identical to the wind speed data in the historical data, and adjust the initial tilt angle according to the correlation index;

[0089] The storage module 154 is configured to store the correlation index.

[0090] In this embodiment, the preferred value of R is 1.5 meters. Such a setting can ensure that the acquisition module 151 can cover a sufficient area to more accurately monitor changes in light intensity and wind speed.

[0091] It is understandable that the acquisition module 151 is used to monitor the changes in light intensity and wind speed in the environment in real time, and provide a basis for adjusting the tilt angle of the photovoltaic panel 132. The judgment module 152 determines whether the tilt angle of the photovoltaic panel 132 needs to be adjusted to adapt to the current environmental conditions based on the collected data. The adjustment module 153 accurately adjusts the tilt angle of the photovoltaic panel 132 according to the instructions of the judgment module 152 and in combination with historical data to ensure that the photovoltaic panel 132 is always in the best light receiving state. The storage module 154 saves all relevant data, including historical wind speed data, correlation index, etc., to provide support for system learning and optimization.

[0092] Specifically, when determining the initial tilt angle of the photovoltaic panel 132 according to the illumination data, it includes:

[0093] The initial tilt angle is obtained by:

[0094]

[0095] Among them, θinit represents the initial tilt angle, Iver represents the light intensity in the vertical direction of the monitoring area; Ihoriz represents the light intensity in the horizontal direction of the monitoring area.

[0096] In this embodiment, the illumination data includes the illumination intensity in the vertical direction of the monitoring area and the illumination intensity in the horizontal direction of the monitoring area; the illumination intensity in the vertical direction of the monitoring area refers to the illumination intensity in the direction perpendicular to the ground, and the illumination intensity in the horizontal direction of the monitoring area refers to the illumination intensity in the direction parallel to the ground. By comparing the illumination intensities in the vertical and horizontal directions, the initial tilt angle θi n it can be calculated to ensure that the photovoltaic panel 132 can obtain the best illumination conditions when it is installed.

[0097] It can be understood that, through the above formula, the initial tilt angle is determined according to the ratio of the light intensity in the vertical direction to the light intensity in the horizontal direction. This calculation method ensures that the photovoltaic panel 132 can obtain an initial position close to the optimal light receiving state when it is installed, thereby improving the initial power generation efficiency of the photovoltaic power station. In practical applications, the setting of the initial tilt angle of the photovoltaic panel 132 is crucial to the performance of the entire photovoltaic power station. The initial tilt angle calculated by the above formula can ensure that the photovoltaic panel 132 can obtain relatively ideal lighting conditions in different seasons and geographical locations, thereby improving the power generation efficiency. In addition, the calculation method is simple and easy to use, and it is convenient to quickly set the initial tilt angle during the installation of the photovoltaic bracket without complicated equipment and operation. For example, assuming that the light intensity in the vertical direction of the monitoring area is 1000 l ux and the light intensity in the horizontal direction is 800 l ux, the initial tilt angle θi n it calculated according to the above formula is: θi n it = arctan (1000 / 800) ≈ 51.34 degrees. This means that in the monitoring area, the photovoltaic panel 132 should be set to form an inclination angle of about 51.34 degrees with the horizontal plane to achieve the best light receiving effect. Such an initial setting is crucial to improving the power generation efficiency of the photovoltaic panel 132, especially in the initial installation stage of the photovoltaic power station.

[0098] Specifically, judging whether to adjust the initial tilt angle according to the wind speed data includes:

[0099] Extract features from wind speed data to obtain wind speed characteristic values;

[0100] The wind speed characteristic value is compared with the wind speed characteristic value threshold, and whether to adjust the initial tilt angle is determined according to the comparison result;

[0101] When the wind speed characteristic value is greater than or equal to the wind speed characteristic value threshold, it is determined that the initial tilt angle is adjusted;

[0102] When the wind speed characteristic value is less than the wind speed characteristic value threshold, it is determined that the initial tilt angle is not adjusted.

[0103] It is understandable that the extraction of wind speed characteristic values ​​generally involves analyzing wind speed data to identify patterns and trends in wind speed changes. Feature extraction may include calculating parameters such as average wind speed, maximum wind speed, and wind speed change rate. These characteristic values ​​can reflect the possible impact of wind on the photovoltaic panel 132, thereby providing a basis for whether the tilt angle needs to be adjusted. The wind speed characteristic value threshold is set based on the design parameters and safety standards of the photovoltaic panel 132, and it represents the threshold of the impact of wind speed on the structural stability of the photovoltaic panel 132. When the wind speed characteristic value exceeds this threshold, it means that the wind may cause damage to the photovoltaic panel 132, so the tilt angle needs to be adjusted to reduce the impact of the wind.

[0104] In this embodiment, the wind speed characteristic value is the wind speed change rate.

[0105] It is understandable that the extraction and comparison of wind speed characteristic values ​​is a dynamic process. The control component 150 continuously monitors the wind speed data and updates the wind speed characteristic values ​​in real time. When the wind speed characteristic value exceeds the threshold, the control component 150 triggers the tilt angle adjustment mechanism, and adjusts the height of the lifting rod 121 by driving the motor, thereby changing the tilt angle of the photovoltaic panel 132. This dynamic adjustment mechanism ensures that the photovoltaic panel 132 can maintain a safe and efficient operating state under the action of wind.

[0106] Specifically, the wind speed data is compared with the historical data, and the initial tilt angle is adjusted according to the comparison result, including:

[0107] When there is historical wind speed data that is the same as the wind speed data in the historical data, the initial tilt angle is adjusted according to the historical photovoltaic panel adjustment coefficient corresponding to the historical wind speed data to obtain an adjusted tilt angle;

[0108] When there is no historical wind speed data identical to the wind speed data in the historical data, the correlation index between the wind speed data and the historical data is calculated, and the maximum value of the correlation index is extracted, which is recorded as the maximum correlation index; the photovoltaic panel adjustment coefficient is determined according to the maximum correlation index, and the initial tilt angle is adjusted according to the photovoltaic panel adjustment coefficient to obtain the adjusted tilt angle.

[0109] It is understandable that the use of historical data is to improve the accuracy and efficiency of the tilt angle adjustment. When there is historical data that is the same as the current wind speed data, the previous successful adjustment experience can be used to guide the current adjustment, which can quickly respond to environmental changes while reducing unnecessary calculations and energy consumption. The historical photovoltaic panel adjustment coefficient is derived based on previous adjustment experience, which reflects the optimal amplitude of the photovoltaic panel 132 tilt angle adjustment under specific wind speed conditions. By applying this coefficient, it can be ensured that the photovoltaic panel 132 maintains the optimal tilt angle under similar wind speed conditions, thereby improving power generation efficiency and structural stability.

[0110] It is understandable that in the absence of the same historical wind speed data, the system needs to determine the new photovoltaic panel adjustment coefficient by calculating the correlation index. The calculation of the correlation index takes into account the similarity between the wind speed data and the historical data. The maximum correlation index represents the most similar degree between the current wind speed and a specific wind speed in the historical data. By selecting the maximum correlation index, the system can find the historical case closest to the current wind speed and determine the adjustment coefficient of the photovoltaic panel 132 accordingly. This method allows the system to make reasonable tilt angle adjustments in the absence of direct historical data, ensuring that the photovoltaic panel 132 maintains optimal performance under changing wind conditions.

[0111] It is understandable that this dynamic adjustment mechanism can significantly improve the adaptability and flexibility of the photovoltaic power station. By real-time monitoring and analysis of environmental data, the photovoltaic bracket can automatically adjust the tilt angle to cope with changes in environmental factors such as wind. This intelligent adjustment can not only protect the photovoltaic panel 132 and reduce damage, but also ensure that the photovoltaic panel 132 is always in the best light receiving state, thereby maximizing power generation efficiency. In addition, by continuously accumulating and analyzing historical data, the system can continue to learn and optimize, further improving the accuracy and efficiency of future adjustments.

[0112] Specifically, the photovoltaic panel adjustment coefficient is determined according to the maximum correlation index, and the initial tilt angle is adjusted according to the photovoltaic panel adjustment coefficient. When the adjusted tilt angle is obtained, it includes:

[0113] The maximum correlation index is obtained by the following formula:

[0114]

[0115] Among them, CImax represents the maximum correlation index; n represents the total number of historical data; ωi represents the weight factor; vi represents the i-th wind speed characteristic value; hi represents the i-th historical wind speed characteristic value; α represents the sensitivity parameter.

[0116] It is understandable that the calculation method of the maximum correlation index takes into account the similarity between historical data and current data, and weights the importance of different historical data through the weight factor ωi. The sensitivity parameter α is used to adjust the sensitivity of the correlation index to wind speed changes, ensuring that the system can accurately identify the historical cases that are most similar to the current wind speed. In this way, the system can calculate an accurate photovoltaic panel adjustment coefficient based on the degree of matching between historical data and current wind speed, so as to accurately adjust the initial tilt angle to adapt to changing environmental conditions. Specifically, the determination of the weight factor ωi is usually based on a statistical analysis of the impact of wind speed characteristic values ​​on the performance of photovoltaic panels 132 in historical data. The size of the weight factor reflects the importance of different historical wind speed characteristic values ​​to the current adjustment decision. For example, if the historical data shows that the performance of the photovoltaic panel 132 is significantly affected under specific wind speed conditions, the weight factor ωi corresponding to the wind speed characteristic value will be set larger to ensure that the system can pay enough attention when the current wind speed characteristic value is similar to it. The setting of the sensitivity parameter α requires balancing the response speed and accuracy of the system to wind speed changes. If the α value is set too high, the system may be too sensitive to small changes in wind speed, resulting in frequent adjustments to the tilt angle, thereby increasing system wear and energy consumption. On the contrary, if the α value is set too low, the system may not be able to respond to significant changes in wind speed in a timely manner, affecting the power generation efficiency and structural safety of the photovoltaic panel 132. Therefore, the setting of the α value needs to comprehensively consider the specific environmental conditions of the photovoltaic power station and the performance requirements of the photovoltaic panel 132 to achieve the best adjustment effect. Through the above method, the photovoltaic bracket can intelligently adjust the tilt angle of the photovoltaic panel 132 based on the real-time monitored environmental data and historical experience.

[0117] It is understandable that by intelligently adjusting the tilt angle of the photovoltaic panel 132, the photovoltaic bracket can effectively disperse the concentrated pressure of the wind on the photovoltaic panel 132. When the wind acts on the photovoltaic panel 132, if the photovoltaic panel 132 maintains a fixed angle, the wind may generate a large concentrated force at the edge of the panel, resulting in structural damage. By real-time monitoring of wind speed and adjusting the tilt angle according to historical data, the photovoltaic bracket can make the wind act on the photovoltaic panel 132 in a more dispersed manner, reducing the concentrated pressure of the wind on a specific area. And adjusting the tilt angle can also make the wind generate a certain lift on the surface of the photovoltaic panel 132, which helps to reduce the downward pressure of the wind on the photovoltaic panel 132, thereby protecting the photovoltaic panel 132 from damage. This ensures to the greatest extent that the photovoltaic panel 132 can remain in a safe and efficient operating state under the action of wind, prolongs the service life of the photovoltaic panel 132, and improves the stability and power generation efficiency of the entire photovoltaic system.

[0118] In this embodiment, the value of ωi is preferably between 0.1 and 0.5 to ensure the rationality of the distribution of weight factors among different historical data; the value of α is preferably between 0.01 and 0.1 to balance the sensitivity and stability of the system to wind speed changes.

[0119] Specifically, the photovoltaic panel adjustment coefficient is determined according to the correlation index, and the initial tilt angle is adjusted according to the photovoltaic panel adjustment coefficient. When the adjusted tilt angle is obtained, it also includes:

[0120] Setting a photovoltaic panel adjustment coefficient interval, the photovoltaic panel adjustment coefficient interval includes a first photovoltaic panel adjustment coefficient, a second photovoltaic panel adjustment coefficient and a third photovoltaic panel adjustment coefficient;

[0121] The maximum correlation index is compared with the first correlation index threshold and the second correlation index threshold respectively, and the photovoltaic panel adjustment coefficient is determined according to the comparison results; wherein the first correlation index threshold is less than the second correlation index threshold;

[0122] When the correlation index is less than or equal to the first correlation index threshold, determining the photovoltaic panel adjustment coefficient as the first photovoltaic panel adjustment coefficient, and taking the product value of the initial tilt angle and the first photovoltaic panel adjustment coefficient as the adjusted tilt angle;

[0123] When the correlation index is greater than the first correlation index threshold and less than or equal to the second correlation index threshold, determining the photovoltaic panel adjustment coefficient to be the second photovoltaic panel adjustment coefficient, and taking the product value of the initial tilt angle and the second photovoltaic panel adjustment coefficient as the adjusted tilt angle;

[0124] When the correlation index is greater than the second correlation index threshold, determining the photovoltaic panel adjustment coefficient to be the third photovoltaic panel adjustment coefficient, and taking the product value of the initial tilt angle and the third photovoltaic panel adjustment coefficient as the adjustment tilt angle;

[0125] The first photovoltaic panel adjustment coefficient is smaller than the second photovoltaic panel adjustment coefficient, and the second photovoltaic panel adjustment coefficient is smaller than the third photovoltaic panel adjustment coefficient.

[0126] It is understandable that by setting different intervals of photovoltaic panel adjustment coefficients, the system can adopt different degrees of tilt angle adjustment strategies according to the different correlation indexes of wind speed data and historical data. The value of the first photovoltaic panel adjustment coefficient is preferably between 0.1 and 0.3, which is suitable for situations where the wind speed changes slightly and the correlation index is low, so as to avoid potential damage to the photovoltaic panel 132 caused by frequent adjustments. The value of the second photovoltaic panel adjustment coefficient is preferably between 0.3 and 0.5, which is suitable for situations where the wind speed changes moderately and the correlation index is medium, so as to ensure that the photovoltaic panel 132 can adapt to wind changes while maintaining structural stability. The value of the third photovoltaic panel adjustment coefficient is preferably between 0.5 and 0.7, which is suitable for situations where the wind speed changes greatly and the correlation index is high, so as to ensure that the photovoltaic panel 132 can respond quickly to wind changes and protect itself from damage. Through this hierarchical adjustment strategy, the system can flexibly adjust the tilt angle of the photovoltaic panel 132 according to the actual situation of the wind speed change, which not only ensures the power generation efficiency, but also ensures the structural safety. And this hierarchical strategy can also reduce unnecessary energy consumption and extend the service life of the photovoltaic panel 132.

[0127] In this embodiment, the first correlation index threshold and the second correlation index threshold are set based on experience, and these two thresholds can effectively distinguish different levels of wind speed changes.
