Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, and in particular to a flexible photovoltaic module system with adaptive light intensity tracking. Background Technology

[0002] With the increasing prominence of the global energy crisis and environmental problems, solar energy, as a clean and renewable energy source, has received widespread attention and application. Photovoltaic modules are the core components of solar energy utilization, and their performance directly affects the efficiency of solar energy utilization. Flexible photovoltaic modules, due to their advantages such as light weight, flexibility, and easy installation, have broad application prospects in building-integrated photovoltaics, portable devices, and transportation. However, most existing flexible photovoltaic modules are fixedly installed and cannot adjust according to changes in the direction of sunlight. This means that they cannot always maintain the optimal angle of sunlight reception at different times of day or in different seasons, thus significantly reducing power generation efficiency. Summary of the Invention

[0003] In view of this, the present invention provides an adaptive light intensity tracking flexible photovoltaic module system. Through the setting of an adaptive adjustment structure, it can automatically adjust the tilt angle of the photovoltaic panel according to changes in the sun's position and light intensity at different times, ensuring that the module always maintains the optimal receiving posture with respect to the direction of sunlight. This overcomes the problem of insufficient light reception caused by the fixed-angle installation of traditional flexible photovoltaic modules, significantly improving the light utilization rate per unit time, thereby greatly enhancing the module's power generation efficiency. Through the setting of limiting components, it can flexibly adapt to and stably fix the flexible photovoltaic panel according to its size, eliminating the need to customize matching brackets for different specifications of flexible photovoltaic panels, effectively... Breaking the limitations of traditional brackets in adapting to specific-sized components, this design significantly improves the versatility and compatibility of flexible photovoltaic modules during installation. It simplifies selection and installation processes, reduces customized production costs due to size differences, and facilitates standardized management and rapid deployment in large-scale applications. The cleaning structure efficiently removes dust from the flexible photovoltaic panel surface, effectively preventing light absorption and blockage caused by dust accumulation. This further enhances the device's solar energy utilization efficiency, significantly increasing power generation output per unit time and shortening the investment payback period for photovoltaic systems, thus improving their economic viability.

[0050] Example 1: Please refer to Figures 1 to 10 :

[0051] This invention proposes a flexible photovoltaic module system with adaptive light intensity tracking, comprising: a fixed support frame 1 and an adaptive adjustment structure 2;

[0052] The top of the fixed support frame 1 is provided with an adaptive adjustment structure 2, which includes:

[0053] A fixed hinge 201 is fixedly connected to one end of the top of the fixed support frame 1. A first shaft pin 2011 is installed on the fixed hinge 201, and a support pad 2012 is fixedly connected to the other end of the top of the fixed support frame 1.

[0054] Connecting support frame 202: It is fixedly connected to the middle of the inner side of the fixed support frame 1. A first lead screw 2021 is provided between the two sets of connecting support frames 202. One end of the first lead screw 2021 is fixedly connected to the drive end of the first motor 2022.

[0055] Movable belt block 203: Located on the outside of the first lead screw 2021, the movable belt block 203 has a first screw hole 2031 in the middle, and guide protrusions 2032 are fixedly connected to both sides of the movable belt block 203. The inner side wall of the connecting support frame 202 has a guide groove 2033, and the guide protrusions 2032 are slidably installed in the guide groove 2033. The top of the movable belt block 203 is fixedly connected to a connecting hinge 2034, and a second shaft pin 2035 is installed on the connecting hinge 2034.

[0056] Mounting frame 204: Located on top of fixed support frame 1, a fixed hinge block 2041 is fixedly connected to the bottom of one end of mounting frame 204. The fixed hinge block 2041 is hinged to the fixed hinge frame 201 via a first shaft pin 2011. An adjusting hinge block 2042 is fixedly connected to the middle of the bottom of mounting frame 204. The adjusting hinge block 2042 is hinged to the top end of double-headed hinge rod 205 via a third shaft pin 2043. The other end of double-headed hinge rod 205 is hinged to connecting hinge frame 2034 via a second shaft pin 2035.

[0057] The light intensity information in different directions is detected in real time by a light sensor (not shown in the figure), and the detected signal is transmitted to the control terminal. The control terminal then starts the first motor 2022 to drive the first lead screw 2021 to rotate. The first lead screw 2021 rotates and engages with the first screw hole 2031 on the moving belt block 203. The moving belt block 203 is limited and guided in the guide groove 2033 by the guide protrusion 2032, so that the first lead screw 2021 drives the moving belt block 203 to move. The moving belt block 203 then drives the double-headed hinge rod 205 through the connecting hinge frame 2034 to rotate the mounting frame 204 around the fixed hinge frame 201, thereby adjusting the angle of the photovoltaic panel 3032.

[0058] Example 2: Based on Example 1, wherein, as Figures 5 to 7 As shown, the mounting frame 204 is provided with a limiting component 3. The limiting component 3 includes a sliding groove 301, a connecting screw 3011, and a fastening nut 3012. The mounting frame 204 has a sliding groove 301. The connecting screw 3011 is movably installed inside the sliding groove 301, and the fastening nut 3012 is engaged on the outside of the connecting screw 3011.

[0059] A fixed frame 302 is fixedly connected to one end of the connecting screw 3011. A movable sliding hole 3021 is provided inside the fixed frame 302. A connecting slide rod 3022 is slidably installed in the movable sliding hole 3021. A compression bottom ring 3023 is fixedly connected to one end of the connecting slide rod 3022. A reset groove 3024 is provided inside the fixed frame 302. The inner wall of the reset groove 3024 fits against the outer wall of the compression bottom ring 3023. A spring 3025 is provided at the top of the compression bottom ring 3023 in the reset groove 3024.

[0060] An extension protrusion 3026 is provided on the outer side of the connecting slide rod 3022. A limit plug 3027 is fixedly connected to the bottom of one end of the extension protrusion 3026, and a pull handle 3028 is fixedly connected to the top of the connecting slide rod 3022.

[0061] The mounting frame 204 has a flexible plate 303 inside. The four sides of the flexible plate 303 have limit holes 3031. The limit rod 3027 is inserted into the limit hole 3031. At the same time, a photovoltaic panel 3032 is provided in the middle of the flexible plate 303.

[0062] By reversing the rotation of the fastening nut 3012, the locking of the connecting screw 3011 is released. Then, the position of the fixed frame 302 is slidably adjusted according to the size of the photovoltaic panel 3032. After adjusting to the appropriate position, the fastening nut 3012 is tightened to lock the connecting screw 3011. Then, the pull handle 3028 is pulled to move the connecting slide rod 3022 upward. The connecting slide rod 3022 then moves the limiting insertion rod 3027 upward. When the limiting insertion rod 3027 is aligned with the limiting insertion hole 3032, the connection is complete. When 031 is aligned, the pull handle 3028 is released. As the connecting slide rod 3022 moves upward, it compresses the spring 3025 in the reset groove 3024 through the compression bottom ring 3023, causing the spring 3025 to undergo elastic deformation. When the pressure is lost, the spring 3025 releases its elasticity, thereby pushing the compression bottom ring 3023 to move. The compression bottom ring 3023 drives the limiting insertion rod 3027 to reset through the connecting slide rod 3022, so that it is inserted into the limiting insertion hole 3031, thereby completing the installation of the photovoltaic panel 3032.

[0063] Example 3: Based on Examples 1 and 2, wherein, as shown in Example 3... Figure 8 and Figure 9 As shown, a cleaning structure 4 is provided on the top of the mounting frame 204. The cleaning structure 4 includes a fixed protrusion 401, a second lead screw 4011, a second motor 4012, and a guide slide rod 4013. Fixed protrusions 401 are fixedly connected to both sides of the mounting frame 204. A second lead screw 4011 is provided between the fixed protrusions 401 on one side. One end of the second lead screw 4011 passes through the fixed protrusion 401 and is fixedly connected to the drive end of the second motor 4012 on the outside. A guide slide rod 4013 is fixedly connected between the fixed protrusions 401 on the other side.

[0064] A connecting band block 402 is provided between the fixed protruding plates 401. The connecting band block 402 is provided with a second screw hole 4021 and a limiting sliding hole 4022 respectively. A rotating support plate 4023 is fixedly connected to the top of the connecting band block 402, and a connecting support plate 4024 is fixedly connected between the rotating support plates 4023.

[0065] A rotating shaft column 403 is provided between the rotating support plates 4023, and a cleaning roller brush 4031 is rotatably installed on the outer side of the rotating shaft column 403.

[0066] By starting the second motor 4012, the second lead screw 4011 is driven to rotate. The second lead screw 4011 rotates and engages with the second screw hole 4021 on the connecting block 402. However, another set of connecting blocks 402 is guided at the upper limit of the guide slide rod 4013 through the limiting slide hole 4022. Thus, the second lead screw 4011 drives the rotating support plate 4023 to move through the connecting block 402. The rotating support plate 4023 drives the cleaning roller brush 4031 to clean the dust on the photovoltaic panel 3032.

[0067] The specific usage and function of this embodiment: In this invention, after fixing the fixed support frame 1 to the corresponding position, the fastening nut 3012 is rotated in the opposite direction to release the lock on the connecting screw 3011. Then, the position of the fixed frame 302 is slid to allow it to be flexibly adjusted according to the size of the photovoltaic panel 3032. After adjusting to a suitable position, the fastening nut 3012 is tightened to lock the connecting screw 3011. Then, the pull handle 3028 is pulled to move the connecting slide rod 3022 upward. The connecting slide rod 3022 then moves the limiting insert rod 3027 upward. When adjusted to the limit insert rod 3027... When 027 is aligned with the limiting insertion hole 3031, the pull handle 3028 is released. As the connecting slide rod 3022 moves upward, it compresses the spring 3025 in the reset groove 3024 via the compression ring 3023, causing the spring 3025 to elastically deform. When the pressure is released, the spring 3025 releases its elasticity, thereby pushing the compression ring 3023 to move. The compression ring 3023, through the connecting slide rod 3022, drives the limiting insertion rod 3027 to reset and insert it into the limiting insertion hole 3031, thus completing the installation of the photovoltaic panel 3032. This allows for flexible adaptation and stability based on the size of the flexible photovoltaic panel. The fixed mounting eliminates the need for custom-made brackets for different sizes of flexible photovoltaic panels, effectively breaking the limitations of traditional brackets that restrict compatibility with specific-sized components. This significantly improves the versatility and compatibility of flexible photovoltaic modules during installation. A light sensor (not shown in the figure) then detects the light intensity from different directions in real time and transmits the detected signals to the control terminal. The control terminal then activates the first motor 2022 to rotate the first lead screw 2021. The first lead screw 2021 engages with the first screw hole 2031 on the moving block 203. The moving block 203, however, is guided by a guide convex... Block 2032 is limited and guided within the guide groove 2033, causing the first lead screw 2021 to drive the moving belt block 203 to move. The moving belt block 203 then drives the double-headed hinge rod 205 through the connecting hinge frame 2034, causing the mounting frame 204 to rotate around the fixed hinge frame 201, thereby adjusting the angle of the photovoltaic panel 3032. This ensures that the photovoltaic panel 3032 always maintains the optimal receiving posture with respect to the direction of sunlight, overcoming the problem of insufficient sunlight reception caused by the fixed angle installation of traditional flexible photovoltaic modules. This significantly improves the sunlight utilization rate per unit time, thereby greatly enhancing the power generation efficiency of the module.
