Description

Technical Field

[0001] This utility model belongs to the field of energy-concentrating membrane technology, and in particular relates to a modular adjustable optical band energy-concentrating membrane device. Background Technology

[0002] In modern agricultural facility cultivation, solar photovoltaic systems, and indoor intelligent lighting, energy-concentrating membrane devices selectively absorb and convert specific spectral bands to achieve efficient utilization and directional control of light energy, becoming a key technological carrier for improving industrial efficiency. In agriculture, plant photosynthesis responds to the 400-700nm visible light band with variety specificity and growth cycle differences; in photovoltaics, solar cells made of different materials exhibit significant differences in spectral absorption peaks.

[0003] Existing photovoltaic (PV) film systems generally employ an integrated, fixed structure. Their light-converting functional layer achieves specific wavelength conversion through doping with rare-earth fluorescent materials or nanocrystalline coatings. However, the spectral conversion range is predetermined by the manufacturing process and cannot be dynamically adjusted according to actual needs. In photovoltaic applications, the mismatch between seasonal changes in sunlight conditions and the spectral response of the battery module leads to fluctuations in energy conversion efficiency of 15%-20%.

[0004] With the increasing demand for dynamic spectral control in emerging fields such as smart agriculture and flexible photovoltaics, the development of energy-concentrating membrane devices with flexible wavelength adjustment capabilities and convenient maintenance has become a common technological requirement in the industry. To address this, we provide a modular, adjustable wavelength-controlled energy-concentrating membrane device to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a modular adjustable optical band focusing membrane device. By combining the support component and the adjustable component, it solves the problem that existing focusing membrane systems generally adopt an integrated fixed structure and cannot be dynamically adjusted according to actual needs.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a modular adjustable optical band focusing film device, comprising a support assembly, an adjustable assembly, and a focusing film body. The adjustable assembly is movably connected to the inner cavity of the support assembly. The support assembly includes a bottom cover and a top cover. The top of the bottom cover has a fitting groove. The focusing film body is laid on the surface of the bottom cover. A locking strip is engaged in the inner cavity of the fitting groove. The top of the locking strip is fixedly connected to the top cover. The top of the top cover has a fitting groove for fitting the adjustable assembly. The inner wall of the fitting groove has an installation groove one. A magnet one is fixedly connected to the inner wall of the installation groove one. A screw is fixedly connected to the top of the top cover. A fixing block is threadedly connected to the surface of the screw. The adjustable assembly includes a light-converting plate. A fixing frame is bonded to the surface of the light-converting plate by adhesive. A second installation groove two is opened at the bottom of the fixing frame. A magnet two is fixedly connected to the inner wall of the second installation groove two.

[0008] The present invention is further configured such that the bottom of the fitting slot and the card strip are both designed with an arc shape, and the arc diameter is greater than the width of the top. The fitting slot and the arc design of the bottom of the card strip form an elastic wedge seal, which improves the flatness and sealing of the energy-concentrating membrane installation and prevents edge warping or foreign object intrusion.

[0009] The present invention is further provided that the inner walls of the bottom cover and the top cover are integrally formed with cross reinforcing ribs, which enhance the deformation resistance of the support components and prevent external forces from damaging the membrane or light-converting plate structure.

[0010] The present invention is further configured such that the fixing block is attached to the top of the fixing frame, and the fixing block is attached to the top of the fixing frame to form a mechanical clamping with the screw, which works in conjunction with the magnetic attraction structure to ensure that the adjustable component remains stable during high-frequency replacement.

[0011] The present invention is further configured such that a groove is provided on the top of the fixing frame, and a pull rope is fixedly connected to the inner wall of the groove. The pull rope provides a point of force for disassembly, which solves the problem of convenient separation when the magnetic structure is tightly adsorbed, and optimizes the human-computer interaction experience.

[0012] The present invention is further configured such that the opposite sides of magnet one and magnet two adopt an opposite attraction design, which ensures the reliability of the magnetic connection. At the same time, the module installation is automatically aligned by magnetic pole positioning to avoid misalignment affecting optical performance.

[0013] The present invention is further configured such that the surfaces of the adjustable component and the support component are on the same horizontal plane, and the surfaces of each component are on the same horizontal plane, thereby eliminating light reflection or scattering loss caused by structural height differences and ensuring the integrity and energy focusing efficiency of the optical system.

[0014] The present invention is further configured such that the energy-concentrating membrane body is embedded into the inner cavity of the fitting slot along with the card strip, and the energy-concentrating membrane is embedded into the fitting slot along with the card strip, thereby realizing glue-free embedded installation of the membrane body, which facilitates the replacement of the membrane body or the whole module later and reduces maintenance costs.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model utilizes the magnetic attraction between the support component and the adjustable component to quickly replace modules with different light conversion bands. Users do not need professional tools; they only need to align the light conversion plate fixing frame with magnet II with magnet I in the fitting groove of the upper cover, and it will be automatically positioned and installed by magnetic attraction. When disassembling, after removing the fixing block, pull the top rope of the fixing frame to easily separate the adjustable component. The replacement time is shortened to minutes. Different light conversion plates can be preset with multiple spectral conversion functions. By replacing different adjustable components, it can adapt to the light requirements of agricultural crops at different growth stages or the spectral response characteristics of photovoltaic modules, solving the pain point of traditional fixed structures that cannot be dynamically adjusted and significantly improving light energy utilization efficiency.

[0017] 2. The support component of this utility model adopts a matching groove and strip structure for the bottom cover and the top cover. The arc design at the bottom of both creates a wedge effect. When the strip is embedded in the matching groove, it can produce elastic deformation and sealing, which not only ensures the flatness and tension of the energy-concentrating membrane body during installation, but also effectively prevents dust and moisture from entering the device. The cross-shaped reinforcing ribs integrally formed on the inner wall of the top cover and the bottom cover can disperse external pressure to avoid deformation of the membrane body under stress, improve the overall structural rigidity, and make the adjustable component flush with the surface of the support component to avoid the formation of protrusions or depressions, ensuring the consistency of the light incident angle. With the embedded installation of the energy-concentrating membrane body along with the strip embedded in the matching groove, stable transmission and efficient energy concentration of the optical system are achieved.

The adjustable assembly 2 has a fitting groove 15, and the inner wall of the fitting groove 15 is provided with a mounting groove 16. A magnet 17 is fixedly connected to the inner wall of the mounting groove 16. A screw 18 is fixedly connected to the top of the cover 12.

A magnet 24 is fixedly connected to the inner wall of the mounting groove 23.

[0029] Specifically: The inner wall of the fitting slot 13 is designed with an arc-shaped flare to accommodate the card strip 14. After the card strip 14 is embedded in the fitting slot 13, a tight connection is achieved through the interference fit of the arc structure. At the same time, the edge of the energy-concentrating membrane body 3 is pressed and fixed between the bottom cover 11 and the top cover 12. The inner wall of the fitting groove 15 is provided with a mounting groove 16. The magnet 17 is bonded to the mounting groove 16 with adhesive. The edge of the top cover 12 is vertically fixed with a screw 18, which passes through the fixing block 1 above the adjustable component 2. 9. The top of the light-converting plate 21 can be pressed by rotating the fixing block 19, forming a double fixation with the magnetic attraction. The surface of the light-converting plate 21 of the adjustable component 2 is bonded to the rectangular fixing frame 22 with a high-strength adhesive. The bottom of the fixing frame 22 is opened with the second mounting groove 23 corresponding to the first mounting groove 16. The second mounting groove 23 is fixed with a magnet 24 with the opposite polarity to the first magnet 17. The attraction of opposite magnetic poles keeps the light-converting plate 21 and the top cover 12 in precise alignment, while allowing for quick disassembly and assembly without tools.

[0030] Example 2

[0031] Please see Figure 1-6 Based on Embodiment 1, the bottom of both the fitting slot 13 and the card strip 14 adopts an arc design, and the arc diameter is greater than the width of its top. The inner walls of the bottom cover 11 and the top cover 12 are integrally formed with cross reinforcing ribs. The fixing block 19 is attached to the top of the fixing frame 22. The top of the fixing frame 22 is provided with a groove 25. The inner wall of the groove 25 is fixedly connected with a pull rope 26. The opposite sides of magnet 17 and magnet 24 adopt an opposite attraction design. The surfaces of the adjustable component 2 and the support component 1 are on the same horizontal plane. The energy-concentrating membrane body 3 is embedded into the inner cavity of the fitting slot 13 along with the card strip 14.

[0032] Specifically: The interlocking slot 13 and the bottom arc design of the clip 14 form an elastic wedge seal, improving the flatness and sealing of the energy-concentrating membrane installation, preventing edge warping or foreign object intrusion; the cross-shaped reinforcing ribs enhance the deformation resistance of the support component 1, preventing external forces from damaging the membrane or the light-converting plate 21 structure; the fixing block 19 fits against the top of the fixing frame 22, and works with the screw 18 to form a mechanical clamping, which works in conjunction with the magnetic attraction structure to ensure the stability of the adjustable component 2 during high-frequency replacement; the pull rope 26 provides a point of force for disassembly, solving the problem of tight magnetic attraction.

At the same time, the magnetic pole positioning enables automatic alignment of the module installation, avoiding misalignment that could affect optical performance. All component surfaces are on the same horizontal plane, eliminating light reflection or scattering losses caused by structural height differences, ensuring the integrity of the optical system and energy focusing efficiency. The energy focusing film is embedded into the fitting slot 13 along with the card strip 14, achieving glue-free embedded installation of the film. This facilitates the later replacement of the film or the entire module, reducing maintenance costs.

[0033] The working principle of this utility model is as follows: The energy-concentrating membrane body 3 is laid on the surface of the bottom cover 11, and the locking strip 14 is embedded into the fitting groove 13. The edge of the membrane body is fixed by the wedge action of the arc structure to form a flat optical transmission base surface. According to the target spectrum requirements, the light-converting plate 21 of the corresponding band is selected, aligned with the fitting groove 15 and placed down. The opposite attraction of the magnet 24 and the magnet 17 automatically attracts and positions the light-converting plate 21. Then, the fixing block 19 is rotated and pressed down to fasten the light-converting plate 21 to the surface of the top cover 12. When it is necessary to switch the light-converting band, the fixing block 19 is removed, the pull rope 26 is pulled out from the groove 25 to separate the magnetic connection, the old module is removed and the new module is installed. The function can be switched without disassembling the overall structure. The cross reinforcing rib enhances the rigidity of the support component 1 and ensures that each component maintains the positional accuracy during long-term use. The flush surface design avoids light incident interference, and the arc groove structure ensures the tension of the membrane body. Together, they achieve efficient light energy convergence and precise band conversion.
