Description

Technical Field

[0001] The present invention relates to the field of photovoltaic energy technology, and in particular to a device and method for adjusting the azimuth angle of a photovoltaic module and a floating photovoltaic platform. Background Art

[0002] In recent years, with the development of offshore floating photovoltaic platform technology, the application scenarios of photovoltaic energy have been greatly expanded. Offshore floating photovoltaic platforms use the vast sea surface as the installation base, which not only avoids the limitation of land resources, but also can use the reflection effect of the sea surface to further improve the power generation efficiency of photovoltaic modules.

[0003] However, the photovoltaic platforms currently widely used to track the azimuth of the sun are fixed designs. The azimuth of the photovoltaic modules of the fixed tracking photovoltaic platforms is fixed after installation and cannot be dynamically adjusted according to the real-time position of the sun and seasonal changes. Since the position of the sun changes with the rotation and revolution of the earth, the fixed tracking method cannot ensure that the photovoltaic modules are always facing the sun, and thus cannot maximize the reception of solar radiation. In particular, when there is a large angle between the position of the sun and the normal of the photovoltaic module plane, the power generation efficiency of the photovoltaic module will be significantly reduced, because the distribution of oblique sunlight on the surface of the photovoltaic module becomes uneven, causing part of the light to be reflected or scattered, and cannot be effectively absorbed by the photovoltaic module and converted into electrical energy.

[0004] In addition, during periods when the sun's position changes greatly, such as in the morning and evening, and in spring and autumn when the sun's altitude is low, fixed tracking will cause a large amount of solar radiation to be wasted. This solar radiation that could have been absorbed by the photovoltaic modules and converted into electrical energy cannot be effectively utilized due to the fixed orientation of the photovoltaic modules, resulting in energy loss.

[0005] In summary, the current photovoltaic platform's fixed design of tracking the sun's azimuth angle has significant limitations in terms of solar radiation reception and energy utilization efficiency, especially when combined with an offshore floating photovoltaic platform, the problem is more prominent. Therefore, a new tracking system is urgently needed to overcome these problems and promote the further development and application of photovoltaic energy technology. Summary of the invention

[0009] Furthermore, the edges of the supporting net are respectively fixed at the edges of the supporting frame, and the edges of the supporting frame can rotate in the pressing block to tighten or loosen the supporting net.

[0011] Furthermore, the magnetically movable tube arm is provided with a damping plate in the column sleeve.

[0012] Further, the lifting drive assembly includes an electromagnetic module, a rebound device and a magnetic drive module; The electromagnetic module is placed at the bottom end of the column sleeve, the magnetic drive module is fixed at the bottom end of the magnetic tube arm, and the rebound device is arranged between the electromagnetic module and the magnetic drive module; the electromagnetic module and the magnetic drive module are respectively connected to the control end of the central control module assembly.

[0013] Furthermore, the central control module assembly includes a central control module, the edges of which are connected to a number of column sleeves through a number of connecting tubes, and a controller and a battery module are provided in the central control module, which are connected to each other; the control ends of the controller and the battery module are connected to the electromagnetic module and the magnetic drive module through a number of connecting tubes and column sleeves; the signal transmission end of the irradiation sensor is connected to the signal receiving end of the controller.

[0014] Furthermore, a control module is provided in the controller, the input end of the control module is connected to the output end of the signal input module, the input end of the signal input module is connected to the output end of the irradiation sensor; the output end of the control module is connected to the input end of the signal output module, the output end of the signal output module is connected to the input end of the drive module, the output end of the drive module is respectively connected to the input end of the battery module and the magnetic drive module; the output end of the battery module is connected to the electromagnetic module.

[0015] In a second aspect, the present invention further provides a method for adjusting the azimuth angle of a photovoltaic module, based on the above-mentioned device for adjusting the azimuth angle of a photovoltaic module, comprising the following steps: The azimuth angles of the supporting grid are respectively set up at the top of the lifting pillars; the photovoltaic modules are placed on the supporting grid, and the solar radiation intensity is monitored in real time by the irradiation sensor. The monitoring results are fed back to the central control module component. The central control module component drives the lifting pillars corresponding to the azimuth angle of the same side of the supporting grid according to the monitoring results to complete the adjustment of the azimuth angle of the photovoltaic module.

[0016] In a third aspect, the present invention further provides a floating photovoltaic platform, comprising a plurality of photovoltaic module azimuth adjustment devices as described above, wherein adjacent adjustment devices are connected by flexible connecting ropes to form a floating photovoltaic platform, and each adjustment device is connected to a gravity anchor by a mooring cable.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a photovoltaic module azimuth adjustment device, which can measure the solar radiation intensity in real time through the irradiation sensor arranged at the edge of the supporting grid, and transmit the data to the central control module component. The central control module component can accurately adjust the lifting support on the lifting magnetic support frame according to the received data, thereby changing the azimuth of the photovoltaic module so that it is always aligned with the optimal position of the sun. This dynamic adjustment can maximize the capture of solar radiation and improve the efficiency of photovoltaic power generation. The design of the lifting magnetic support frame allows the photovoltaic module to be adjusted in azimuth, so that the device can adapt to the changes in the position of the sun at different times, seasons and geographical locations.

[0018] Furthermore, the support frame with a field-shaped structure provides a solid support foundation, which can effectively disperse the weight of the photovoltaic modules and ensure the stability of the entire system. The design of the pressure block is not only used to fix the position of the support frame on the lifting pillar, but also enhances the structural strength at the end corners to prevent deformation or displacement caused by factors such as weight or wind. The support frame is fixed to the lifting pillar by the pressure block, which simplifies the installation process and makes the installation and azimuth adjustment of the photovoltaic module more convenient. The pressure block fine-tunes the support frame to ensure the optimal position and angle of the photovoltaic module. Fixing the irradiation sensor on the pressure block ensures that the sensor can accurately measure the intensity of solar radiation without being affected by the support frame or the support net. This design improves the accuracy of irradiation measurement and provides reliable data support for the central control module components.

[0019] Furthermore, the support frame edge is designed to rotate in the pressure block to adjust the tension of the support net. This adjustment method can adjust the tension of the support net according to actual needs to adapt to photovoltaic modules of different sizes and weights. By adjusting the tightness of the support net, it can be ensured that the photovoltaic modules will not slip or loosen during transportation, installation and use, thereby improving the safety of the entire system. Furthermore, the lifting drive assembly is driven by the control end of the central control module assembly to realize the automatic adjustment of the height of the lifting pillar, which not only improves the flexibility of the adjustment, but also ensures the accuracy of the adjustment, so that the photovoltaic module can be adjusted in real time according to the changes in the position of the sun. The bottom end of the magnetic tube arm is sleeved in the column sleeve and abuts against the lifting drive assembly, ensuring the stability of the magnetic tube arm during the lifting process. At the same time, the top end of the magnetic tube arm abuts against the azimuth of the supporting grid, providing a stable support for the photovoltaic module. The material and structural design of the magnetic tube arm and the column sleeve enable the lifting pillar to withstand the weight of the photovoltaic module and the effects of external factors such as wind load, ensuring the safety and stability of the system.

[0020] Furthermore, the damping plate not only reduces vibration, but also strengthens the connection strength between the magnetic tube arm and the column sleeve. This enhancement makes the entire lifting support more stable and reliable when bearing the weight of photovoltaic modules and external loads.

[0021] Furthermore, the electromagnetic module is placed at the bottom end of the column sleeve, and the magnetic drive module is fixed at the bottom end of the magnetic arm. Through the control of the central control module assembly, the electromagnetic module can generate a changing magnetic field, thereby driving the magnetic drive module and the magnetic arm connected to it to perform lifting and lowering movements. This design achieves precise control of the lifting process, allowing the photovoltaic module to be adjusted in real time according to changes in the position of the sun. The rebound device is arranged between the electromagnetic module and the magnetic drive module, which plays a buffering and stabilizing role. During the lifting process, the rebound device can absorb and disperse the impact energy to prevent damage to the system due to sudden acceleration or deceleration. At the same time, the rebound device can also maintain the stability of the system, making the lifting process smoother and more controllable.

[0022] Furthermore, the central control module is connected to each column sleeve through a connecting pipe, realizing centralized control of multiple lifting drive components, which not only improves the system's integration, but also makes the system's structure more compact and modular. Each component can be maintained and upgraded separately. When a component fails, it can be easily removed and replaced with a new one without large-scale disassembly and reconstruction of the entire system.

[0023] Furthermore, the irradiation sensor transmits the real-time monitored solar irradiation intensity signal to the signal input module, which is then transmitted to the control module after preliminary processing. The control module performs intelligent analysis based on these signals and makes corresponding control decisions, realizing real-time monitoring and intelligent response to solar irradiation intensity, and improving the automation and intelligence level of the system. Through the control module, centralized control and management of multiple lifting drive components in the entire photovoltaic power generation system can be achieved. This centralized control strategy not only simplifies the operation process, but also improves the overall performance and stability of the system.

[0024] The present invention also provides a method for adjusting the azimuth angle of a photovoltaic module. By using an irradiation sensor to monitor the solar radiation intensity in real time and feeding back the monitoring results to a central control module component, the system can understand the position and radiation intensity of the sun in real time. Based on this information, the central control module component drives the lifting and lowering of the lifting pillars corresponding to the azimuth angle of the same side of the supporting grid, so that the photovoltaic module is always facing the sun, thereby maximizing the absorption of solar energy. By accurately adjusting the azimuth angle of the photovoltaic module, the system can ensure that the photovoltaic module maintains the optimal power generation angle at any time, which not only improves the efficiency of photovoltaic power generation, but also extends the service life of the photovoltaic module. The present invention also provides a floating photovoltaic platform, in which each adjustment device can independently and accurately adjust the azimuth of the photovoltaic module according to the position and irradiation intensity of the sun, ensuring that the photovoltaic module always faces the sun, thereby maximizing the capture of solar energy and improving power generation efficiency. The platform adopts a floating design and can float naturally according to the fluctuations of the water surface, adapting to different water level changes while maintaining the stability and power generation efficiency of the photovoltaic module. Adjacent adjustment devices are connected by flexible connecting ropes, which not only enhances the overall structural stability of the platform, but also enables the platform to better adapt to the fluctuations and deformation of the water surface, improving the flexibility and adaptability of the system.
