[0024] Embodiment 1 See also Figure 1 , Figure 2 and Figure 3 A floating photovoltaic platform device that can actively adjust the angle of photovoltaic components is characterized in that it includes a floating body, a photovoltaic mechanism, a central control system 3, a connecting floating body 4 and a gravity anchor 7. The photovoltaic mechanism is installed on the floating body, the floating body is connected to the gravity anchor 7, the gravity anchor 7 is placed in the water area, a number of floating bodies are arranged, and the several floating bodies are connected by connecting the floating body 4. The central control system 3 is installed on the connecting floating body 4, and the central control system 3 is respectively connected to the floating body and the photovoltaic mechanism. The floating body includes an adjusting air cushion 5 and a supporting floating body 6. The adjusting air cushion 5 is arranged on the supporting floating body 6, the photovoltaic mechanism is arranged on the adjusting air cushion 5, and the supporting floating body 6 is respectively connected to the connecting floating body 4 and the gravity anchor 7.

[0025] In this embodiment, the gravity anchor 7 is stably placed in the water area to ensure that the entire device can be firmly fixed, and the floating body including the supporting floating body 6 and the adjusting air cushion 5, the photovoltaic mechanism, the connecting floating body 4 and the central control system 3 are assembled and connected to form a complete photovoltaic array. After starting, the central control system 3 will perform a series of self-test procedures, including checking the status of each sensor, confirming the connection status of the photovoltaic mechanism, verifying the charging and discharging function of the adjusting air cushion 5, etc., to ensure that the entire device is in good working condition. The central control system 3 collects data on environmental factors such as the position of the sun, light intensity, wind speed, and wind direction in real time through built-in sensors or external environmental monitoring equipment. Based on the collected environmental data, the central control system 3 will use the built-in algorithm to analyze and calculate to determine the current optimal photovoltaic module angle. This calculation process will comprehensively consider multiple factors such as light intensity, solar incident angle, and power generation efficiency of photovoltaic modules. According to the calculation results, the central control system 3 will send a control signal to the adjusting air cushion 5 to adjust its height and shape by charging and discharging air, thereby achieving precise adjustment of the angle of the photovoltaic mechanism. This process is real-time and can be dynamically adjusted according to changes in the position of the sun. When the photovoltaic mechanism receives sunlight at the best angle, its photoelectric conversion efficiency will be significantly improved, thereby generating more electricity. This electricity is transmitted to the power grid through cables for people to use. The central control system 3 also monitors the operating status of the photovoltaic mechanism in real time, including parameters such as current, voltage, and temperature. Once an abnormal situation is found, the system will immediately issue an alarm and take corresponding protective measures to prevent the fault from further expanding. In addition to real-time monitoring, the central control system 3 also supports remote maintenance functions. The operation and maintenance personnel can remotely debug and troubleshoot the system through a network connection, greatly reducing the cost and time of operation and maintenance. The stability of the gravity anchor 7 and the buoyancy design of the float ensure the stability and safety of the entire device in the water. Even in the event of large wind and waves or water flow impact, the device can maintain a stable floating state. The central control system 3 also has an emergency response mechanism that can automatically adjust the angle of the photovoltaic mechanism or take other protective measures to ensure the safety of the device and personnel in the event of extreme weather or emergencies.

[0026] The photovoltaic mechanism includes a photovoltaic component 1 and a photovoltaic bracket 2 . The photovoltaic bracket 2 is installed on an adjusting air cushion 5 . The photovoltaic component 1 is laid on the photovoltaic bracket 2 . The photovoltaic component 1 is connected to a central control system 3 .

[0027] In this embodiment, the photovoltaic assembly 1 is fixed on the adjustable air cushion 5 through the photovoltaic bracket 2, and can maintain a stable installation angle, thereby ensuring that the maximum amount of sunlight is received. The connection between the photovoltaic assembly 1 and the central control system 3 enables the system to monitor and adjust the angle of the photovoltaic assembly in real time to adapt to changes in the position of the sun, thereby further improving the power generation efficiency. The adjustable air cushion 5 not only provides additional buoyancy, but also can stabilize the photovoltaic bracket 2 by adjusting the height of the air cushion, thereby enhancing the wind and wave resistance of the entire photovoltaic mechanism. The photovoltaic assembly 1 is laid on the photovoltaic bracket 2, so that maintenance personnel can more easily approach and check the status of the photovoltaic assembly. The remote monitoring function of the central control system 3 enables operation and maintenance personnel to understand the operating status of the photovoltaic mechanism in real time, discover and deal with problems in time, and reduce operation and maintenance costs. By adjusting the height of the air cushion 5, the overall height of the photovoltaic mechanism can be flexibly adjusted to adapt to different water environments and lighting conditions, so that the photovoltaic mechanism can use the water space more efficiently and increase the power generation capacity per unit area. The real-time monitoring and emergency response mechanism of the central control system 3 can ensure that timely measures are taken in emergency situations to protect the safety of the photovoltaic mechanism and personnel.

[0028] See also Figure 4 and Figure 5 The regulating air cushion 5 and the supporting float 6 are both hollow structures. A ventilation pipe 51 and a supporting air bag 54 are arranged inside the regulating air cushion 5, and a control air pump 52 is arranged inside the supporting float 6. One end of the ventilation pipe 51 is connected to the control air pump 52, and the other end of the ventilation pipe 51 is connected to the outer surface of the regulating air cushion 5. A flow valve 57 is arranged on the ventilation pipe 51, and a delivery air path 53 is connected between the control air pump 52 and the supporting air bag 54.

[0029] The hollow structure of the regulating air cushion 5 and the internal ventilation pipe 51 of this embodiment enable the control air pump 52 to inflate and discharge air to the supporting air bag 54 through the air delivery path 53, thereby changing the height and shape of the air cushion, so that the photovoltaic mechanism can perform real-time angle adjustment according to the change of the sun's position, ensuring that the sunlight is always received at the best angle, thereby improving the power generation efficiency. After being inflated, the supporting air bag 54 can provide a stable supporting force, ensuring the stability of the regulating air cushion 5 and the photovoltaic mechanism. The design of the hollow structure also helps to reduce the weight of the entire device and improve the floating performance in the water. The provision of the ventilation pipe 51 and the flow valve 57 enables maintenance personnel to easily inspect and repair the pipes inside the air cushion. and airbags, the flow valve 57 is also used to adjust the flow of gas, so as to achieve precise control of the height of the air cushion. The hollow structure of the supporting float 6 enables it to provide sufficient buoyancy to support the entire photovoltaic platform device to float stably in the water, reducing the dependence on the water environment, so that the device can operate efficiently under various water conditions. The internal structure of the supporting float 6 can ensure that it has sufficient strength and rigidity to withstand the weight of the photovoltaic mechanism and the regulating air cushion 5 and various challenges of the water environment. The control air pump 52 is integrated inside the supporting float 6, making the entire control system more compact and efficient, reducing the interference of the external environment, and improving the stability and reliability of the control system. By adjusting the angle of the photovoltaic mechanism in real time, the photovoltaic module can always receive sunlight at the best angle, thereby significantly improving the power generation efficiency. The modular design and integrated control system make operation and maintenance more convenient and efficient, reducing the operation and maintenance costs. The device can be adaptively adjusted according to the water environment and weather conditions, ensuring efficient operation in different environments, due to the increase in power generation and the reduction in operation and maintenance costs.

[0030] A plurality of support air bags 54 are provided.

[0031] In this embodiment, multiple support airbags 54 disperse the weight of the device in the water, making the entire photovoltaic platform device more stable. Distributed support helps to reduce the risk of the device tilting or overturning due to excessive force on a single point. The increase in the number of support airbags 54 means that the buoyancy provided will also increase accordingly, ensuring that the device can float stably under various water conditions, especially in environments with deep water or rapid water flow. Multiple support airbags 54 are inflated and deflated separately to achieve more precise angle adjustment. This design allows the photovoltaic mechanism to be more flexibly adjusted according to changes in the position of the sun to maximize the capture of solar energy. If one or more of the support airbags 54 fail or are damaged, the other airbags still provide sufficient support and buoyancy to ensure the safe operation of the entire device. This design improves the fault tolerance and reliability of the device. By adjusting the amount of inflation and deflation of different airbags, the device can better adapt to different water environments and weather conditions. For example, in an environment with fast current, the stability of the device can be improved by increasing the amount of air inflated in the airbags; in a calm environment, the amount of air inflated in the airbags can be appropriately reduced to lower the height of the device. The provision of multiple supporting airbags 54 makes it easier for maintenance personnel to inspect and repair the airbags. If an airbag fails, it can be replaced or repaired separately without affecting the operation of the entire device.

[0032] An irradiance sensor 21 is installed on the edge of the floating body. The irradiance sensor 21, the control air pump 52 and the flow valve 57 are respectively connected to the central control system 3.

[0033] The irradiance sensor 21 of this embodiment can monitor the irradiance of sunlight in real time, that is, the intensity and energy distribution of sunlight. The central control system 3 adjusts the angle of the photovoltaic module in real time according to the data provided by the irradiance sensor 21, so that it always faces the optimal incident angle of sunlight, captures sunlight to the greatest extent, and improves the power generation efficiency of the photovoltaic module. By connecting the flow valve 57 to the central control system 3, the gas flow in the ventilation pipe 51 can be accurately controlled, and the height and shape of the air cushion 5 can be adjusted to further optimize the angle of the photovoltaic module. The irradiance sensor 21, the control air pump 52 and the flow valve 57 are all connected to the central control system 3 to realize centralized monitoring and management of the entire system and improve the reliability and safety of the system. Through the remote monitoring function of the central control system 3, the operation and maintenance personnel can understand the operating status of the system in real time and reduce the frequency of manual inspections. At the same time, accurate control and adjustment also help to extend the service life of the equipment and reduce the operation and maintenance costs.

[0034] A system support 41 is provided on the connection float 4 , and the system support 41 carries the central control system 3 .

[0035] The setting of the system bracket 41 of this embodiment distributes the weight of the central control system 3 to the floating body 4, avoids structural damage caused by excessive force on a single point, improves the stability of the entire device, enhances the stability of the entire device under wind and wave conditions, and ensures that key components such as the central control system 3 are not affected and operate normally. The modular design of the system bracket 41 makes the installation process more convenient, and quickly installs the central control system 3 and other components at the predetermined position. When the central control system 3 needs to be maintained or repaired, these components can be easily approached through the system bracket 41, which reduces the difficulty and time cost of maintenance. Through the flexible design of the system bracket 41, the spatial layout of the entire device is optimized, so that the connection between the various components is more compact and reasonable, and the space utilization rate is improved. The design of the system bracket 41 is adjusted according to different water environments and installation requirements to adapt to different application scenarios. The stable support of the system bracket 41 ensures the stable operation of components such as the central control system 3, thereby improving the response speed of the entire photovoltaic power generation system. Through the load-bearing function of the system bracket 41, the risk of system failure caused by loose or damaged components is reduced, and the reliability of the entire system is improved.

[0036] Electrical equipment is placed inside the central control system 3, and the electrical equipment includes an inverter and a controller.

[0037] The inverter of this embodiment can convert the direct current generated by the photovoltaic module into alternating current, which is a common form of electrical energy in household, industrial and commercial electricity consumption. This conversion enables the photovoltaic power generation system to directly provide power to various electrical equipment, thereby improving the utilization rate and convenience of electrical energy. In the process of converting electrical energy, the inverter can reduce energy loss, improve the efficiency of the entire photovoltaic power generation system, reduce power generation costs, and improve economic benefits. The inverter is usually equipped with multiple protection functions such as overvoltage protection, undervoltage protection, and overload protection. It can cut off the power supply in time when the system is abnormal to prevent equipment damage and safety accidents. The inverter can adapt to the needs of different voltages and currents and provide suitable power conversion solutions for photovoltaic power generation systems of various sizes. The controller can receive signals from equipment such as irradiance sensors and convert them according to preset programs. The controller can remotely monitor the operation status of the photovoltaic power generation system, including voltage, current, power factor and other parameters, and timely discover and solve problems. The controller has a fault diagnosis function, which can automatically detect and give prompts when a system fault occurs, helping the operation and maintenance personnel to quickly locate the problem and repair it. The controller can record the system's operating data, analyze and process it, provide decision support for the operation and maintenance personnel, and optimize the system's operating strategy. The collaborative work of the inverter and the controller enables the photovoltaic power generation system to operate more efficiently and stably, improving the overall performance. Through remote monitoring and fault diagnosis functions, the operation and maintenance personnel can more conveniently manage the photovoltaic power generation system, reducing the difficulty and cost of operation and maintenance.

[0038] The regulating air cushion outer wall 56 of the regulating air cushion 5 adopts a pleated structure.

[0039] The pleated structure of this embodiment enables the regulating air cushion 5 to change its shape and height more easily during the inflation and deflation process, so that the photovoltaic power generation system can quickly adjust the angle and height of the photovoltaic module according to the change of the sun's position or the different water conditions, so as to capture sunlight to the greatest extent and improve the power generation efficiency. The outer wall of the pleated structure can increase the strength and stability of the regulating air cushion 5. In the water environment with large winds and waves, the pleated structure effectively disperses the external pressure and prevents the air cushion from being damaged due to excessive force on a single point. At the same time, this structure can also increase the contact area between the air cushion and the floating body, and improve the firmness and stability of the connection. The design of the pleated structure enables the regulating air cushion 5 to occupy a smaller space in the contracted state, which is convenient for storage and transportation. When it is needed, it only needs to be expanded by inflation, thereby improving space utilization and convenience. The outer wall of the pleated structure can adapt to the changes in different water environments and climatic conditions. For example, in an environment with large temperature changes, the pleated structure adapts to the changes in the internal pressure of the air cushion by expansion and contraction, thereby maintaining the stability and reliability of the air cushion. The outer wall of the pleated structure can reduce the wear and aging of the air cushion during long-term use. Since the pleated structure can disperse the external pressure, the force on the air cushion is more even, thereby reducing the wear and aging caused by excessive force at a single point. At the same time, this structure can also increase the flexibility of the air cushion, making it more durable.

[0040] The adjustable tilt angle range of the adjustable air cushion outer wall 56 of the adjustable air cushion 5 is not less than 15 degrees.

[0041] The adjustability of the tilt angle of this embodiment enables the photovoltaic modules to be flexibly adjusted according to the changes in the position of the sun in different time periods, so as to capture sunlight to the greatest extent and improve the power generation efficiency of the photovoltaic power generation system. In different time periods and seasons, the altitude angle and azimuth angle of the sun will change. The adjustable tilt angle can ensure that the photovoltaic modules always face the optimal incident angle of sunlight and reduce power generation losses caused by shadows. In different water environments, such as lakes, rivers or oceans, conditions such as water flow and wind speed will be different. By adjusting the tilt angle of the air cushion, the photovoltaic platform device can better adapt to changes in these environmental conditions and maintain the stability of the system. In water environments with strong winds and waves, the appropriate tilt angle can reduce the impact of waves on the photovoltaic platform device and reduce the risk of system damage caused by wind and waves.

[0042] Embodiment 2 In the working method of a floating photovoltaic platform device capable of actively adjusting the angle of photovoltaic components in the first embodiment, the gravity anchor 7 fixes the device in the water, the supporting float 6 provides buoyancy for the device, and the inflation and deflation of the adjusting air cushion 5 is controlled by the central control system 3 to change the height and shape of the adjusting air cushion 5, and the angle of the photovoltaic mechanism is actively adjusted. The photovoltaic mechanism converts solar energy into electrical energy, and the electrical energy is output through the central control system 3.

[0043] This embodiment can adjust the angle of the photovoltaic mechanism in real time by the precise charging and discharging control of the regulating air cushion 5 by the central control system 3, so that it always faces the optimal incident angle of the sun, which not only ensures that the photovoltaic module can capture solar energy to the maximum extent, but also significantly improves the photoelectric conversion efficiency. Since the photovoltaic mechanism can continuously receive sunlight at the optimal angle, the power generation of the entire device is significantly improved. At the same time, the active adjustment of the angle also helps to reduce the power generation fluctuations caused by changes in the position of the sun and improve the stability of power generation. The device can be adaptively adjusted according to different water environments (such as water depth, wave conditions, etc.) and weather conditions (such as wind speed, wind direction, solar altitude angle, etc.), ensuring efficient operation in different environments. The central control system 3 is not only responsible for angle adjustment, but also has remote monitoring and fault diagnosis functions. This reduces the frequency of manual inspections, reduces operation and maintenance costs, and improves the reliability and safety of the system. The modular design of the floating body allows the entire device to be easily expanded as needed to adapt to different power generation needs. At the same time, the height adjustment function of the air cushion 5 also optimizes the utilization of the water space, so that the device can operate efficiently in various water environments. As a renewable energy utilization method, the device not only reduces dependence on traditional energy, but also reduces carbon emissions, which meets the requirements of environmental protection and sustainable development. Due to the increase in power generation and the reduction in operation and maintenance costs, the device has significant advantages in economic benefits and can bring considerable profits in the long run.

[0044] Embodiment 3 See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present embodiment provides a floating photovoltaic platform device that can actively adjust the angle of photovoltaic modules, which is mainly composed of a supporting float 6, an adjusting air cushion 5, a connecting float 4, a central control system 3, a photovoltaic bracket 2, a photovoltaic module 1 and other structures.

[0045] The floating platform adopts a modular design, with a square ring-shaped supporting float 6 under a single module, and a ring-shaped regulating air cushion 5 installed above the float. The regulating air cushion 5 supports the truss-type photovoltaic support 2, and the photovoltaic components 1 are laid flat on the photovoltaic support 2. The single floating platform has a simple structure and is easy to build and install.

[0046] The connection between the floating bodies is completed through the connecting floating body 4, which is made of highly elastic material, such as rubber material, and is in the shape of a ring. Its material and shape make the connecting floating body 4 have compression and tension resistance, and can be used as a reliable connection between photovoltaic platforms. In addition, the central control system 3 is carried on the top of the connecting floating body 4, and the central control system 3 stores electrical equipment such as inverters and controllers, which are mainly used to converge and output the power generation of the photovoltaic module 1, and to make decisions and adjust the optimal tilt angle of the photovoltaic module 1.

[0047] The supporting float 4 and the regulating air cushion 5 of the photovoltaic platform are both hollow structures. The supporting float 4 stores components such as the control air pump 52 and the flow valve 57, and the regulating air cushion 5 stores components such as the supporting air bag 54 and the ventilation pipe 51. The supporting air bag 54 is connected to the control air pump 52 through the delivery air path 53, and the ventilation pipe 51 is connected to the top of the control air pump 52, which is controlled by the flow valve 57. An irradiance sensor 21 is installed on the edge of the photovoltaic float, which can judge the light intensity and the maximum light angle. The information and control of the control air pump 52, the flow valve 57, the irradiance sensor 21 and other components are summarized in the central control system 3 for joint management. Four supporting air bags 54 are placed inside each regulating air cushion 55. Through the coordinated lifting and lowering of the four air bags, the inclination of the air cushion is adjusted, thereby driving the angle change of the photovoltaic bracket 2 and the photovoltaic module 1.

[0048] The angle adjustment principle of the photovoltaic platform is as follows: after the irradiance tracks the angle with the maximum light intensity, the angle information is provided to the central control system 3. After the central control system 3 analyzes the movement amplitude of the air cushion, it controls the four air pumps to inhale or exhaust. The adjustment speed can be controlled by the flow valve 57 to achieve the rapid rise or fall of the four supporting airbags 54, driving the photovoltaic module 1 to reach the maximum light position.

[0049] The outer wall of the adjustable air cushion 5 is made of flexible material and has a pleated structure, which is convenient for the lifting and contraction of the air cushion, and the adjustable tilt angle range is not less than 15 degrees. Since the four sides are adjusted jointly, the adjustable air cushion 5 can adjust the tilt angle and azimuth of the photovoltaic module 1 at the same time.
