[0002] my country boasts abundant sunshine across 76% of its land area, with relatively even distribution of solar energy resources. Photovoltaic power generation produces no noise or pollutant emissions, and its application technology is mature, safe, and reliable. Solar energy is the cleanest, safest, and most reliable energy source of the future. Developed countries are making the development and utilization of solar energy a key part of their long-term energy revolution plans, and the photovoltaic industry is increasingly becoming another industry experiencing explosive growth internationally, following the IT and microelectronics industries.

[0003] Photovoltaic modules for photovoltaic (PV) power generation consist of high-efficiency crystalline silicon solar cells, a backsheet, and a frame. Conventional PV modules generate electricity from direct sunlight, utilizing only the energy in the short to medium wavelength range (e.g., wavelengths <1100nm). The technology of using ordinary reflective films to directly reflect light onto the back of the PV module increases the irradiance on the back, achieving the purpose of enhancing brightness through reflection.

[0004] In existing photovoltaic modules, reflective enhancement devices can cause damage to the reflective film and photovoltaic modules when exposed to severe weather conditions (such as sandstorms and hail), thereby increasing the maintenance costs of the reflective film and photovoltaic modules.

One end of the pull rope passes through the ball sleeve, the support column, and the reflective film plate four in sequence, and is connected to the retraction and extension drive assembly. The other end is connected to each of the three reflective film plates three. By pulling the pull rope through the retraction and extension drive assembly, the pull rope pulls the reflective film plate three, causing each pair of reflective film plates three to retract toward the photovoltaic module.

[0014] As a preferred embodiment of the present invention, the retraction and extension drive assembly is an electric telescopic rod. By extending and retracting the electric telescopic rod, the pull rope and the pull rod are pushed and pulled to achieve the opening and closing control of the concave mirror structure.

[0015] As a preferred embodiment of the present invention, a rotating and tilting mechanism is fixedly installed on the mounting base.

[0018] As a preferred embodiment of the present invention, the mounting base is provided with a waste removal groove, and the waste removal groove is located directly below the arc-shaped groove plate.

[0019] The present invention has the following beneficial effects:

[0020] This invention controls the tilt angle between the connecting plate and the mounting plate by rotating the mounting plate around the worm gear through the forward and reverse rotation of the motor. This allows for a single control source to control the rotation and tilt of the mounting plate, enabling the reflective film and photovoltaic module to track the sun and improve the utilization of sunlight.

[0021] By controlling the lever with an electric telescopic rod, several reflective films can be retracted and the photovoltaic modules can be moved, so that the reflective films can wrap around the outside of the photovoltaic modules, reducing the impact of severe weather on the outer surface of the photovoltaic modules and the inner surface of the reflective films.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0042] Example 1:

[0043] Please see Figure 1 As shown, the present invention is a reflective light-enhancing device for photovoltaic modules, including a mounting base 1, a mounting plate 3 on the mounting base 1, a reflective light-enhancing mechanism 4 fixedly mounted on the mounting plate 3, and a photovoltaic module 5 disposed in the middle of the reflective light-enhancing mechanism 4; by retracting the reflective light-enhancing mechanism 4, the outer side of the photovoltaic module 5 is wrapped, thereby achieving protection for the outer side of the photovoltaic module 5 and the inner side of the reflective light-enhancing mechanism 4.

[0044] Please see Figure 5 , Figure 6 and Figure 8As shown, the reflective light enhancement mechanism 4 includes a retraction drive assembly 41, a pull rope 44, and a reflective film plate 48. The retraction drive assembly 41 is fixedly connected to the right side of the mounting plate 3. A support column 43 is fixedly installed on the reflective film plate 48, and a ball sleeve 410 is fixedly installed on the top of the support column 43. Several sets of reflective film plates 47 arranged in a ring are sequentially hinged to the outside of the reflective film plate 48. A reflective film plate 46 is hinged to the side of the reflective film plate 47 away from the reflective film plate 48. Two reflective film plates 45 are hinged to the side of the reflective film plate 46 away from the reflective film plate 45. The reflective film plate 48, reflective film plate 47, reflective film plate 2, and reflective film plate 45 are combined to form a concave mirror structure. In the working state, the photovoltaic module 5 is at the focal point of the concave mirror structure. Through the reflection of sunlight by the reflective film, the reflected light will shine on the outer wall of the photovoltaic module 5, illuminating the side of the photovoltaic module 5 away from the sunlight, thereby achieving the purpose of reflective light enhancement.

[0045] Among them, a tension spring 49 in a stretched state is connected between any two adjacent groups of reflective film plates 47. One end of the pull rope 44 passes through the ball sleeve 410, the support column 43 and the reflective film plate 48 in sequence, and is connected to the retraction drive component 41. The other end is connected to each of the reflective film plates 47. By pulling the pull rope 44 through the retraction drive component 41, the reflective film plates 47 are pulled, so that each group of reflective film plates 47 retracts towards the photovoltaic module 5.

[0046] By controlling the extension and retraction of the pull rope 44 through the extension and retraction drive assembly 41, the extension and retraction of the reflective film can be controlled through the cooperation between the pull rope 44 and the tension spring 49. The extension and retraction drive assembly 41 is an electric telescopic rod, but it is not limited to an electric telescopic rod; it can also be a winch as in the prior art, providing power for the closing of the concave mirror structure.

[0047] The pull rope 44 is divided into several strands. One end of the undispersed pull rope 44 passes through the ball sleeve 410 and the support column 43 and is installed on the retraction and extension drive assembly 41. One end of the dispersed pull rope 44 passes out of the ball sleeve 410 and is fixed to the reflective film plate 45 in a corresponding manner.

[0048] Please see Figure 9 As shown, a U-shaped grooved wheel 442 is rotatably connected to the ball sleeve 410. The U-shaped grooved wheel 442 supports and guides the pull rope 44. The U-shaped grooved wheel 442 supports and guides the transmission of the pull rope 44, reduces wear at the connection between the outer wall of the pull rope 44 and the ball sleeve 410, and improves the service life of the pull rope 44.

[0049] Please see Figure 9 and Figure 13As shown, a pull rod 42 is slidably connected within the inner cavity of the support column 43. A pulley 441 is installed at the top of the pull rod 42, and a pull rope 44 passes through the pulley 441 and is fixedly connected to the ball sleeve 410. The design of the pulley 441 increases the retraction stroke of the pull rope 44. The pulley 441 design increases the stroke of the pull rope 44 when it is pulled, i.e., S... 拉绳 =2S 滑轮 .

[0050] Please see Figure 14 As shown, a guide groove 431 is provided on the support column 43, and a slider 432 that cooperates with the guide groove 431 is fixedly installed on the pull rod 42. The slider 432 is fixedly connected to the photovoltaic module 5. By pushing and pulling the pull rod 42 through the extension and retraction drive component 41, the photovoltaic module 5 moves along the axial direction of the support column 43.

[0051] The design of guide groove 431 and slider 432 facilitates the movement of photovoltaic module 5 by pull rod 42; at the same time, it guides the movement of pull rod 42 and prevents axial rotation of pull rod 42.

[0052] Please see Figure 6 , Figure 7 ,and Figures 10-12 As shown, an mounting plate 3 is fixedly mounted with a mounting disk 421. A turntable 423 is rotatably connected to the center of the mounting disk 421. A pull rod 42 is connected to the retraction and extension drive assembly 41. The outer wall of the pull rod 42 is provided with a spiral groove 422 that cooperates with the turntable 423. The turntable 423 is provided with several arc-shaped grooves 424 distributed in a ring. A pull plate 426 corresponding to the arc-shaped grooves 424 is slidably connected to the mounting plate 421 to guide the movement of the pull plate 426. One end of the pull plate 426 is rotatably connected to a mounting post 425 that cooperates with the arc-shaped groove 424. A guide plate 427 is fixedly mounted on the side of the reflective film plate 3 47 away from the photovoltaic module 5. The guide plate 427 is slidably connected to the end of the pull plate 426 away from the mounting post 425. The tilt angle of the reflective film plate 3 47 is controlled by the axial movement of the pull rod 42.

[0053] The axial movement of the pull rod 42 drives the rotating disk 423 to rotate through the spiral groove 422, and drives the mounting column 425 through the spiral groove 422 to achieve telescopic control of the pull plate 426. This telescopic control of the pull plate 426 controls the angle of the reflective film 47.

[0054] The number of arc-shaped grooves 424, mounting columns 425, pull plates 426, guide plates 427, and reflective film plates 47 are the same.

[0055] Please see Figure 6 and Figures 8-12As shown, the extension and retraction drive assembly 41 is an electric telescopic rod. By extending and retracting the electric telescopic rod, the pull rope 44 and the pull rod 42 are pushed and pulled to realize the opening and closing control of the concave mirror structure.

[0056] In severe weather, the electric telescopic rod pushes the pulley 441, causing the photovoltaic module 5 to move axially along the support column 43. Simultaneously, the pulley 441 slides within the support column 43, causing the pull rope 44 to slide on the outer wall of the U-shaped groove wheel 442. This retraction of the pull rope 44 gathers the top of the reflective film. The tension spring 49 pulls the connection between reflective film 1 45 and reflective film 2 46 and reflective film 3 47. Simultaneously, the spiral groove 422 and the turntable 423 work together to rotate the arc groove 424 on the turntable 423, retracting the pull plate 426 and causing reflective film 3 47 to rotate inwards. This wraps the outside of the photovoltaic module 5 with the reflective film, reducing damage to the outside of the photovoltaic module 5 and the inside of the reflective film caused by harsh environments. Conversely, the electric telescopic rod can be used to unfold the reflective film.

[0057] Example 2:

[0058] Please see Figure 2 As shown, a specific application of this embodiment is as follows: a rotating tilting mechanism 2 is fixedly installed on the mounting base 1. The rotating tilting mechanism 2 includes a connecting plate 22, which is rotatably connected to the mounting base 1. The connecting plate 22 is hinged to the mounting plate 3. A driving component 21 is installed on the mounting base 1. A telescopic component 23 is connected to the connecting plate 22. A connecting rod 24 is hinged to the top of the telescopic component 23. The connecting rod 24 is hinged to the mounting plate 3. Through the design of the driving component 21 and the telescopic component 23, the rotation and elevation angle of the photovoltaic module using the reflective light enhancement device are controlled to achieve the effect of light tracking.

[0059] Please see Figure 3 As shown, the drive assembly 21 includes a motor 211, which is mounted on the mounting base 1. A worm gear 212 is fixedly mounted on the output end of the motor 211. A worm wheel 213 meshes with the outer surface of the worm gear 212. The worm wheel 213 is fixedly mounted at the rotation axis of the connecting plate 22. The design of the worm gear 212 and the worm wheel 213 provides a certain locking effect on the connecting plate 22, which facilitates locking the orientation of the reflective light enhancement device for the photovoltaic module.

[0060] Please see Figure 3 and Figure 4As shown, the telescopic component 23 includes a threaded sleeve 231 rotatably connected to the end of the connecting plate 22. A threaded rod 232 is threadedly connected inside the threaded sleeve 231. The top of the threaded rod 232 is hinged to the connecting rod 24. A rotating component 25 is fixedly installed on the mounting base 1. The rotating component 25 includes an arc-shaped groove plate 253 fixedly installed on the mounting base 1 and a spur gear 251 fixedly installed at the bottom of the threaded sleeve 231. Two sets of racks 254 located inside the arc-shaped groove plate 253 are fixedly connected to the mounting base 1. One set of racks 254 is an inner ring rack and the other is an outer ring rack. The racks 254 mesh with the spur gear 251, and the two sets of racks 254 are located on both sides of the spur gear 251. By utilizing the cooperation between the spur gear 251 and the racks 254, the rotating threaded sleeve 231 controls the telescopic movement of the threaded rod 232, so as to control the elevation angle of the reflective light enhancement device for photovoltaic modules.

[0061] Please see Figure 3 As shown, the mounting base 1 has a debris removal groove 252, which is located directly below the arc-shaped groove plate 253. The design of the debris removal groove 252 facilitates the removal of debris that enters the inner side of the arc-shaped groove plate 253, reducing the impact of debris entering the inner side of the arc-shaped groove plate 253 on the fit between the spur gear 251 and the rack 254.

[0062] In use, the motor 211 drives the worm gear 212 to rotate in both directions, which in turn drives the worm wheel 213 to rotate, thereby driving the connecting plate 22 to rotate. This allows the reflective film and photovoltaic module 5 to rotate in sync with the sun. At the same time, the connecting plate 22 drives the threaded sleeve 231 to rotate around the worm wheel 213. The engagement between the spur gear 251 and the rack 254 drives the threaded sleeve 231 to rotate in both directions, thereby controlling the height of the threaded rod 232. This, in turn, controls the connecting rod 24, which in turn controls the tilt angle of the reflective light enhancement device for the photovoltaic module, enabling the photovoltaic module 5 and the reflective film to track the sun.

[0063] Taking the Northern Hemisphere, where China is located, as an example: Please refer to [link / reference]. Figure 3 Specifically, during the morning period: the drive component 21 drives the connecting plate 22, and with the cooperation of the spur gear 251 and the inner ring rack 254, the spur gear 251 rotates counterclockwise, causing the threaded rod 232 to move axially downward in the inner cavity of the threaded sleeve 231, pulling the connecting rod 24, thereby controlling the elevation angle of the photovoltaic module 5 and the reflective film on the mounting plate 3, so that the elevation angle of the photovoltaic module 5 and the reflective film gradually increases;

[0064] Afternoon period: Driven by the drive component 21, the connecting plate 22 is driven, and with the cooperation of the spur gear 251 and the outer ring rack 254, the spur gear 251 rotates clockwise, which drives the threaded rod 232 to move axially upward in the inner cavity of the threaded sleeve 231, pushing the connecting rod 24, thereby controlling the elevation angle of the photovoltaic module 5 and the reflective film on the mounting plate 3, so that the elevation angle of the photovoltaic module 5 and the reflective film gradually decreases.
