Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic technology, and in particular to a flower-shaped solar photovoltaic module. Background Technology

[0002] With the rapid development of solar energy technology, the efficiency and reliability of photovoltaic modules have become core research directions. Traditional solar photovoltaic systems mostly adopt a planar fixed layout, which, although simple in structure, has significant drawbacks in practical applications:

[0003] Low solar utilization efficiency: Most fixed photovoltaic panels are regular-shaped monolithic panels that cannot dynamically adjust the illumination range according to changes in the sun's azimuth angle, resulting in a significant reduction in the area exposed to sunlight during dawn and dusk or seasonal changes. According to statistics, the average efficiency loss of planar layouts during non-midday hours can reach more than 30%. Although existing adjustable brackets can achieve angle adjustment, they are mostly single-axis or dual-axis mechanical structures with limited adjustment range. Moreover, when multiple photovoltaic panels are linked together, they are prone to creating shadows, which actually reduces the overall efficiency.

[0004] Insufficient wind resistance: Traditional support structures mostly use homogeneous rods and rigid connections. In strong wind environments, stress concentration can easily lead to structural deformation or even breakage. Some improvement solutions enhance stability by adding counterweights or stay cables, but this significantly increases installation costs and floor space, and makes it difficult to adapt to sudden gust loads.

[0005] Maintenance and Adaptability Deficiencies: Existing photovoltaic panels are mostly installed in a fixed manner, requiring manual operation for cleaning and replacement, resulting in high maintenance costs. In addition, environmental factors such as strong winds have a significant impact on the equipment, easily causing breakage, damage, or even collapse, while traditional systems lack the ability to monitor the status of units in real time and to adaptively optimize them.

[0006] To address the aforementioned issues, there is an urgent need in this field for a photovoltaic module solution that can balance high-efficiency power generation, dynamic adaptability, and high reliability. Summary of the Invention

[0007] The purpose of this invention is to provide a flower-shaped solar photovoltaic module to overcome the shortcomings of the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This application discloses a flower-shaped solar photovoltaic module, including a device base and a flower-shaped photovoltaic array. The device base is provided with a plurality of cross support rods, one end of which is connected to the device base and the other end of which is connected to the flower-shaped photovoltaic array. The flower-shaped photovoltaic array includes a flower center and a plurality of petal parts, with the petal parts surrounding the outside of the flower center. Solar photovoltaic panels are provided on the flower center and the petal parts.

[0010] When the lighting environment changes, such as the time of day and the long seasonal transition, the solar photovoltaic panels with multi-angle petal-shaped sections can adaptively adjust the light coverage of the solar photovoltaic panels in every time period, season, and even weather condition. The cross support rods, through mutual support and traction, can evenly balance the gravity to form a stable mechanical balance. When subjected to external forces, they can decompose and dissipate the external forces, thereby reducing the impact of external forces on the device and increasing the stability of the structure.

[0011] The flower center section includes a flower center plate, and the bottom of the flower center plate is provided with several flower center connecting seats. The flower center connecting seats are connected to one end of the cross support rod. The petal section includes a petal plate, and the petal plate is connected to the side of the cross support rod. The petals are arranged in an overlapping direction at an oblique angle. Under direct sunlight, the effective light-receiving area of ​​the solar photovoltaic panels on the petals and flower center section is fully unfolded, and through its three-dimensional structure, the effective light-receiving area is greater than its planar area. When the angle of sunlight shifts, the sunlight coverage range of the solar photovoltaic panel changes accordingly due to the change in the angle of sunlight.

[0012] Through the overlapping structure design of the flower center and petals, the solar panel can maximize the coverage area of ​​sunlight at multiple times. At noon, under the direct sunlight, the solar panel can cover 120%-200% of its surface area, thus maximizing the utilization of energy.

[0013] At the same time, the three-dimensional arrangement of the flower center and petals can significantly improve the aesthetics, making this device not only a functional facility but also an ornamental one.

[0014] Preferably, the connection point of the cross support rod with the device base forms contour line one, and the connection point with the flower center connecting seat forms contour line two. The size of contour line two is larger than the size of contour line one. The top of the cross support rod is inclined to the outside of the device base and has an inverted cone structure. The cross support rods are combined with each other and support each other, so that the force is uniform and stable.

[0015] As an inverted conical truss structure with a smaller bottom and a larger top, the structure disperses wind and gravity loads and reduces local stress concentration by increasing the top support area. Each cross support rod decomposes the force and distributes it to each support point. At the same time, the gravity of the cross support rods further strengthens the structure, thereby improving its stability.

[0016] Preferably, a support connecting seat is connected between the cross support rods, and the support connecting seat is connected to the cross support rods and is movably connected to the cross support rods.

[0017] The support connector is attached to the cross support rod and can serve as a reinforcement point between the cross support rods, thereby improving the dynamic stability of the device.

[0018] Preferably, the cross support rod has a movable groove, and the movable groove has a height adjustment connector. The height adjustment connector is connected to the support connecting seat. The height adjustment connector includes a height driving component movably connected to the movable groove, and the height driving component is poweredly connected to the height adjustment connector.

[0019] The support connector can be height adjusted. With height adjustment, when the cross support rod has a certain angle, it will drive the cross support rod to tilt. At the same time, it will drive the flower center part connected to the top of the cross support rod to rise and fall. The vertical height of the petal plate is adjusted through mechanical transmission.

[0020] Furthermore, in the event of extreme weather, to ensure safety, the height of the support connector can be adjusted to lower the center of gravity and prevent tipping.

[0021] At the same time, kinetic energy can be absorbed by the buffer spring, which can more effectively deal with crosswinds and other situations.

[0022] By using the universal joint as the connection structure between the support connector and the cross support rod, it can adapt to movement and adjustment at various angles.

[0023] Preferably, the height driving component includes a drive motor mounted on the cross support rod, the output end of the drive motor being poweredly connected to a drive rod, a movable connector being connected to the drive rod, and the movable connector being interconnected with the height adjustment connector; the drive rod is a threaded rod, the movable connector being provided with a threaded hole, and the threaded rod and the threaded hole being mutually engaged and connected.

[0024] The drive motor is connected to the movable connector via a threaded rod, converting rotational motion into linear displacement. This drives the height adjustment connector to precisely control the height of the support connector, thereby adjusting the height and tilt angle of the petal plate. At the same time, the threaded drive design has a self-locking function, which ensures that the position is stable after adjustment and will not tilt or collapse.

[0025] Preferably, the bottom of the petal plate is provided with several petal connecting seats, and the cross support rod is provided with several petal support rods. One end of the petal support rod is connected to the cross support rod, and the other end is connected to the petal connecting seat.

[0026] The petal section is connected to the cross support rod by several petal support rods. With 3 to 5 petal support rods, the various parts of the petal section can be stably supported. Multi-degree-of-freedom adjustment can be achieved through multi-point hinges, or it can be connected through universal joints to ensure the stability of the support structure.

[0027] Preferably, the petal support rod is an arc-shaped telescopic rod with uniform curvature. The telescopic end of the petal support rod is connected to the petal connecting seat, and the petal connecting seat is located at different angles of the petal plate. By telescoping the petal support rod at different angles, the tilt and angle change of the petal plate can be achieved.

[0028] The arc-shaped telescopic rod experiences uniform force during extension and retraction, while the multi-angle petal support rods extend and retract in tandem, allowing for independent adjustment of the tilt angle of the petal plates in each area to adapt to complex lighting conditions.

[0029] Preferably, the flower center plate and petal plate are provided with a number of plug-in positions, and a solar photovoltaic panel is detachably connected to each plug-in position. The solar photovoltaic panel is electrically connected to the main control board inside the flower center plate and petal plate through the plug-in positions. A cover is connected to each plug-in position, and the cover covers the top of the photovoltaic panel.

[0030] The plug-in ports use standardized interfaces, allowing for quick and uniform replacement and disassembly of photovoltaic panels. The cover design is dustproof and waterproof, protecting the electrical contact points from environmental corrosion and preventing foreign objects from obstructing the surface of the photovoltaic panels.

[0031] Preferably, the petal plate is equipped with several sensors, including a resistance sensor and a tilt sensor. The sensors are connected to the main control board via wires and wireless communication. The main control board calculates and adjusts the displacement of the petal plate and the cross support rod based on the resistance, tilt angle, wind speed, and solar azimuth angle data transmitted by the sensors.

[0032] Preferably, the main control board calculates the quantitative efficiency of the solar photovoltaic panel based on data acquired by the sensors, and calculates specific safety data. When the safety conditions are met, the execution mode with the maximum power generation efficiency is prioritized; otherwise, emergency protection is implemented, and the petal panels and cross support rods are retracted to ensure minimal damage.

[0033] Preferably, the calculation of the safe range includes real-time monitoring of the external force on the resistance sensor and obtaining a safe threshold by calculating the resistance value. When the detected resistance value does not exceed the safe threshold, it is determined to be within the safe range.

[0034] The beneficial effects of this invention are:

[0035] (1) In this invention, the petal part of the flower-shaped photovoltaic array surrounds the outside of the flower center part and is arranged in an oblique direction. When the sunlight is direct, the effective light-receiving area of ​​the solar photovoltaic panels of the petal part and the flower center part is fully unfolded. The three-dimensional overlapping structure makes its effective light-receiving area greater than the area occupied by the plane. At noon, the light coverage area can reach 120%-200% of the area occupied by the plane.

[0036] (2) Through the structural design of the petal part and the petal support rod and the cross support rod, the solar photovoltaic panel of the petal part at multiple angles can adaptively adjust the light coverage when the light environment changes, such as during dawn and dusk or when the seasons change, so as to make fuller use of the sunlight at different times and seasons and reduce the loss of light utilization efficiency.

[0037] (3) Through the inverted conical structure of the cross support rods, they are combined and supported to ensure uniform force distribution, expand the top support area, disperse wind load and gravity load, reduce local stress concentration, and at the same time, the cross support rods are connected by support connecting seats, which can be used as reinforcement points to improve dynamic stability.

[0038] (4) The support connecting seat can move on the movable slot of the cross support rod through the height adjustment connector to adjust the height. This not only drives the petal plate to adjust the vertical height and tilt angle, but also lowers the center of gravity in extreme weather to prevent tipping and further enhance the structural stability.

[0039] (5) The petal part is connected to the cross support rod by 3-5 petal support rods. The petal support rods are arc-shaped telescopic rods with uniform curvature. Their telescopic ends are connected to the petal connecting seats at different angles of the petal plate. This design can achieve multi-degree-of-freedom adjustment through multi-point hinges. The multi-angle petal support rods can extend and retract in tandem, independently adjusting the tilt angle of the petal plate in each area, adapting to complex lighting conditions, and ensuring the stability of the support structure.

[0040] (6) By collecting data on resistance, wind speed, solar azimuth and irradiance in real time, the system dynamically calculates the optimal tilt angle and maximizes power generation efficiency within the safe resistance threshold (240N). When there is a certain risk, but it is still controllable (240N-320N), the system automatically reduces the load and controls the efficiency loss within 15% to avoid structural overload.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0051] See Figures 1-4 This invention provides a flower-shaped solar photovoltaic module, including a device base 1. The device base 1 is polygonal and is stably installed on the ground and can be firmly fixed. A slot is provided on the device base 1 to accommodate cross support rods 3. 6 to 10 rotating brackets are provided in the slot. Support rod seats 302 are rotatably connected to the rotating brackets. All support rod seats 302 form a regular polygon, and the rotation direction of the support rod seats 302 forms the same inscribed circle.

[0052] See Figure 7A drive motor 303 is provided on the support rod seat 302 or the cross support rod 3. The output end of the drive motor 303 is powered by a threaded rod, i.e., a drive rod 301. The threaded rod has threads and is connected to a movable connector. The movable connector has a matching threaded hole. The support rod seat 302 is provided with a cross support rod 3. The cross support rod 3 has a movable groove 304 inside. The movable connector is slidably connected in the movable groove 304. After the drive motor 303 rotates, it drives the threaded rod to rotate. Through the threaded hole structure on the sliding movable connector, it can be translated, thereby realizing the movement of the movable connector. Through the synchronous movement of multiple movable connectors, the support connecting seat 5 is driven to rotate and rise synchronously with it, thereby realizing the rise and fall of the support connecting seat 5 and the top flower center part 201. At the same time, the flower center part 201 and the cross support rod 3 are connected by several flower center connecting seats 2012, and the flower center connecting seats 2012 and the cross support rod 3 are connected by universal joints, which can freely adjust the angle.

[0053] See Figure 5 , 6 The bottom of the flower center part 201 is provided with a flower center adaptation groove 2011, and a flower center connecting seat 2012 is movably connected in the flower center adaptation groove 2011. The flower center part 201 moves in an adaptable manner along with the cross support rod 3, thereby adapting to the end position change caused by the tilt of the cross support rod 3, so as to maintain the stability of the connection.

[0054] The flower center portion 201 can be a complete polygonal whole, or it can be a number of fragments separated by several lines. If it is a fragment, each fragment has at least two flower center connecting seats 2012 to ensure the integrity of its flower center graphic.

[0055] A number of petal portions 202 are provided around the flower center portion 201. Each petal portion 202 includes an irregular petal plate. One side of the petal plate is perpendicular to the tangent circle of the flower center portion 201. A number of petal connecting seats 2022 are provided on the petal portion 202. Petal support rods 4 are provided on the cross support rods 3. At least three petal support rods 4 are connected to the petal connecting seats 2022 of the petal portion 202 and are connected by universal joints.

[0056] The petal support rod 4 is a telescopic, curved rod structure with a uniform curvature, which ensures the continuity and stability of telescopic movement. The telescopic movement can be achieved by electric, hydraulic, or pneumatic means. By adjusting the degree of telescopic movement of different petal support rods 4, the orientation, position, height, and other conditions of the petal plate can be adjusted, thereby realizing the movement and adjustment of the petal plate.

[0057] Several petal adaptation grooves 2021 are also provided at the bottom of the petal plate. Petal connecting seats 2022 are movably connected to the petal adaptation grooves 2021. The function of the petal adaptation grooves 2021 is to accommodate the displacement of the end of the petal support rod 4 on the petal plate during the extension and retraction process, so as to maintain the stability of the connection.

[0058] Through the overlapping structure design of the flower center 201 and the petal part 202, the light coverage area can be maximized at multiple time periods. At noon, under the direct sunlight, the light coverage area of ​​the photovoltaic panel can reach 120%-200% of its planar occupied area, which can maximize the utilization of energy.

[0059] At the same time, the three-dimensional arrangement of the flower center and petals can significantly improve the aesthetics, making this device not only a functional facility but also an ornamental one.

[0060] The universal joint connection includes the connection methods of cross universal joints and ball joint universal joints. The universal joint connection method can stably support the rotation at any angle while maintaining the connection relationship.

[0061] Mechanical stops are provided on the cross support rod 3 and the petal support rod 4. The mechanical stops are located on the periphery of the universal joint and limit the rotation angle of the universal joint. The opening angle is 30°-150°.

[0062] From the moment the sun enters the recognition range of the solar photovoltaic panel of this device, the petal support rod 4 in the petal part 202 of the solar photovoltaic panel can be extended and retracted to adjust the deflection angle of the petal panel. Under this condition, different deflection angles will cause the current petal panel to present different angles with the direct direction of sunlight. When the petal panel is perpendicular to the current direct direction of sunlight, the utilization efficiency of sunlight can be maximized.

[0063] However, the scope of this application is not limited to situations where the direct sunlight is perpendicular to the solar photovoltaic panel. In this embodiment, the solar energy utilization efficiency meets the requirements when the angle between the direct sunlight and the solar photovoltaic panel is greater than 30°.

[0064] According to the preset tilt angle and tilt direction of the petal panel, under extreme direct sunlight angles or in different regions, the tilt direction and tilt angle of the entire petal panel can be adjusted by adjusting the extension length of two of the three petal support rods 4, so that the angle of the petal panel can meet the applicable angle of the solar photovoltaic panel; in particular, the angle of each petal panel is adjusted individually so that each petal panel can be adapted to the direct sunlight angle at the current time.

[0065] When encountering strong winds, the rotation of the drive motor 303 can drive the height drive component 305 to move, thereby moving the support connecting seat 5. Since the size of the support connecting seat 5 is fixed, the height of the support connecting seat 5 will change, which will in turn cause the angle of the cross support rod 3 to change, so that each cross support rod 3 tilts synchronously. The descent of the support connecting seat 5 will lower the center of gravity and prevent it from being blown by strong winds and collapsing.

[0066] Meanwhile, the petal support rod 4 can be extended and retracted. When retracted, the petal support rod 4 will drive the petal plate to retract, reducing the windward area. The angle can also be adjusted by the petal support rod 4, thus reducing the impact of strong winds and preventing equipment damage and tipping.

[0067] The device base 1 has 8 suction cups at the bottom, which are adsorbed by a vacuum pump to maintain a negative pressure of -70kPa.

[0068] Photovoltaic panel power generation efficiency Angle of incidence of the sun The relationship is:

[0069] ;

[0070] in: The nominal efficiency of the photovoltaic panel. It is the angle of incidence of the sun (i.e., the actual azimuth of the sun). This can be obtained through a tilt sensor.

[0071] Within a safe range, the overall global efficiency is:

[0072] ;

[0073] The safe range is: the resistance value experienced by the petal plate does not exceed the safe threshold.

[0074] The petal plate is equipped with a resistance sensor, specifically a miniature strain force sensor, which is installed at the connection between the petal support rod and the petal connector. When subjected to external wind force, the petal plate is stressed, and the petal support rod is stressed through the petal support seat. The resistance sensor monitors and records the resistance in real time.

[0075] resistance value The calculations include:

[0076] ;

[0077] in, As a safety threshold, in one feasible embodiment, , .

[0078] when If the situation is deemed dangerous, the safety protection mechanism is triggered, and the protection of the solar photovoltaic panel is implemented by controlling the petal support rod and the drive motor.

[0079] Includes graded safety ranges: Safety range: It operates in a mode of maximum efficiency.

[0080] Level 1 Response: It requires load reduction adjustment, which reduces efficiency but ensures safety.

[0081] Level 2 Response: In an emergency, the petal-shaped plate and cross support rods are retracted, and the suction cups are activated for adsorption. Power generation efficiency is no longer a consideration, and safety is maximized.

[0082] Level 3 Response: An alarm should be triggered, and external measures should be taken for emergency protection to ensure safety and avoid losses.

[0083] The petal panel is also equipped with a tilt sensor, specifically a MEMS tilt sensor, which detects the tilt angle of the petal panel in real time. It is installed at the bottom of the petal panel. When the tilt angle of the petal panel is detected to be abnormal, an alarm is sent to the main control board, which then controls the drive motor and petal support rod to protect the solar photovoltaic panel.

[0084] Abnormal conditions include: the difference between the tilt angle and the preset angle exceeds the threshold, indicating that it has been affected by external force and has become distorted. The preset angle is the angle implemented by the petal support rod under the current condition of the petal board. Specifically, the threshold is 2%~5%.

[0085] Within safe limits, the optimal tilt angle that maximizes power generation efficiency should be given priority. The calculation method is as follows:

[0086] ;

[0087] in: For photovoltaic panels at tilt angle The efficiency of the lower;

[0088] G is for implementing irradiance. It reflects the intensity of light;

[0089] The resistance borne by the petal plate and petal support rod;

[0090] v represents the ambient wind speed.

[0091] We can also calculate the actual resistance using tilt angle and wind speed. for:

[0092] ;

[0093] in: These are the coefficients fitted through wind tunnel experiments, reflecting air density and structural aerodynamic characteristics;

[0094] This represents the measured static load.

[0095] Power generation efficiency With tilt angle The relationship is:

[0096] ;

[0097] in: The angle of incidence of the sun; The tilt angle is when the photovoltaic panel is directly facing the sun. At that time, the efficiency of photovoltaic panels .

[0098] The device base is equipped with wind speed sensors, specifically ultrasonic anemometers, which are installed on the outside of the device base. There are 4 to 8 of them, which monitor the wind speed in the current environment in real time. When the wind speed is detected to be too fast, the device will protect the solar photovoltaic panels.

[0099] If the wind speed sensor data conflicts with the drag data, the drag data will be used first, and the data will be sent to the main control board to remind manual verification.

[0100] The protection mode includes: the drive motor quickly retracts the petal plate and adjusts the windward angle of the petal plate to the minimum through the petal support rod; the suction cup at the bottom of the device base is activated to increase the suction force of the device base.

[0101] Example 1: The device base 1 of this application is made of aluminum alloy with dimensions of 2000mm×2000mm×50mm; the cross support rod 3 is made of carbon fiber composite material with a bottom cross section of 100mm×100mm and a length of 1800mm for each support rod. The top is connected to the flower center connector 2012 through a universal ball joint.

[0102] There are 6 cross support rods, which are inclined outward at 12° to form an inverted cone structure. The top outline L2=1500mm, the bottom outline L1=1200mm, and L2 / L1=1.25. Through this geometric design, the load is distributed to all directions and the base, reducing the risk of tilting and tipping.

[0103] The movable groove 304 inside the cross support rod 3 is 20mm wide and is used to install a height adjustment connector. The height adjustment connector is a universal joint connector. The support connection seat 5 is a hexagonal structure and is evenly connected to the 6 cross support rods 3.

[0104] The flower core board is a splicing type of hexagonal board, consisting of two splicing boards that can be combined to form a hexagon. The spliced ​​hexagonal board has a diameter of 1200mm and a thickness of 10mm. There are 12 interlocking positions on the surface, and copper alloy spring contacts are embedded in the interlocking positions.

[0105] There are 6 petal plates, and their long sides are parallel to the side wall of the flower center plate that is closest to it. The long side dimension is 800mm. There are 6 insertion positions on the surface of the petal plates, and copper alloy spring contacts are embedded in the insertion positions.

[0106] In the drive mechanism, the drive motor 303 is a 57HS09 stepper motor with a rated torque of 1.2 N·m. It has a built-in 17-bit absolute encoder and is installed in the internal cavity of the cross support rod 3. The output end is connected to a stainless steel threaded rod, which drives the movable connecting part that cooperates with it. The movable connecting part is equipped with a slider, which is slidably connected to the movable groove 304 to limit the sliding. A buffer spring is provided between the slider and the movable groove 304 to increase the ability to withstand instantaneous impacts.

[0107] For every revolution of the motor, the moving connector moves 2mm, causing the support connector 5 to move, thereby tilting the cross support rod 3. This allows for adjustment of the opening angle of the petal part 202, increasing the light-receiving area and preventing mutual interference that could cause shading.
