DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1, reference Figure 1 to Figure 4, which is the first embodiment of the present invention, and this embodiment provides a movable and self-cleanable reflective film device, including: a power generation component 100 includes a main support 101, a double-glass component 102 arranged on the main support 101, and a reflective diaphragm 103 arranged between the two double-glass components 102; a movable component 200 includes a movable support 201 arranged on the main support 101, a driving component 202 arranged on the movable support 201, a cleaning component 203 arranged on the movable support 201, and a recovery component 204 arranged on the cleaning component 203; the cleaning component 203 is used to clean the reflective diaphragm 103, and the recovery component 204 is used to recover water.

[0035] Among them, a group of double-glass components 102 are installed on the main frame 101, and the number of double-glass components 102 in a group is two. The reflective diaphragm 103 is located between the two double-glass components 102. By reflecting sunlight to the back of the double-glass components 102, the double-sided power generation of the double-glass components 102 is achieved.

[0036] It should be noted that the double-glass module 102, also known as a double-sided photovoltaic module, is an innovative photovoltaic technology consisting of two pieces of glass with photovoltaic cells sandwiched inside. Compared with the traditional single-glass module, the double-glass module 102 has the following characteristics: First, the double-glass module 102 has good impact resistance and weather resistance, and the protection of the glass makes it more advantageous in bad weather. Second, since it can utilize double-sided illumination, the double-glass module 102 can more effectively convert light energy in a sunny environment and increase power generation. Third, its structural design makes the module less prone to aging and less affected by environmental factors, reducing maintenance costs. Fourth, the double-glass module 102 usually uses more environmentally friendly materials, does not contain harmful substances, and has a higher recycling rate.

[0037] In summary, through these characteristics, the double-glass module 102 has gradually occupied a place in the photovoltaic market.

[0038] It should be noted that the reflective diaphragm 103 plays a key role in the photovoltaic system of the double-glass component 102. The double-glass component 102 can utilize double-sided illumination, that is, the front side directly receives sunlight, and the optical fiber on the back side through the reflective diaphragm 103 can also be utilized. The reflective diaphragm 103 can reflect scattered light from the bottom or other surfaces to the back side of the photovoltaic panel, thereby increasing the total illumination intensity; by increasing the illumination intensity, the reflective diaphragm 103 can significantly improve the power generation efficiency of the double-glass component 102, especially in the case of insufficient illumination or poor reflection of light, which is particularly obvious under the effect of the reflective diaphragm 103; moreover, the reflective diaphragm 103 can evenly reflect light to various parts of the photovoltaic panel to avoid the decrease in detection efficiency due to uneven local illumination; at the same time, the reflective diaphragm 103 can reduce the impact of shadows in the surrounding environment on the photovoltaic panel, ensuring that both sides of the photovoltaic panel can receive sufficient illumination; the reflective diaphragm 103 can reflect more light to the back side of the photovoltaic panel at different time periods of the day, especially in the morning and evening when the light is weak, to extend the effective illumination time, thereby increasing the power generation.

[0039] In this example photovoltaic project, the specific application of the reflective diaphragm 103 is as follows:

[0040] Site layout: Prefabricated pipe piles and brackets are used on the ground, and they are installed at a fixed angle of 12 degrees facing south. The top of the pile is 1 meter from the ground, the bracket column is 1 meter, and the north-south distance is 6.5 meters. Huawei SUN2000-(196KTL-H0) inverter is used. JAM72D30-535 / MB double-glass modules 102 produced by Hefei JA Solar are used, and each group of 26-28 modules form a string.

[0041] Test plan: select the PV strings connected to two adjacent groups of inverters for test and comparison, one group is installed with reflective film, and the other group is maintained in normal state. The test range is from the 8th row to the 10th row from north to south, except for the group on the east side of the 10th row; check that the two groups of inverters and PV strings have the same quantity and environment, 28 components in each string, no abnormality in the cables, unlimited load on the inverter, etc.; the test personnel install the solar reflection device; the operation and maintenance personnel record the voltage, current and inverter power generation load of the PV strings of inverters No. 4 and 5 every day.

[0042] Under conditions of clear weather and normal lighting conditions, the data of the two groups of inverters were compared and analyzed, and the increased power consumption of the inverter equipped with the reflective film was calculated, thereby evaluating the effect of the reflective film.

[0043] Through the above design and implementation, the reflective film device can effectively improve the utilization efficiency of the double-glass module 102 photovoltaic panel to sunlight, while reducing the cost of manual cleaning and ensuring the continuous and efficient power generation of the photovoltaic system.

[0044] Example 2, reference Figure 5 and Figure 6 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference is that: the driving component 202 includes a moving slide 202a arranged on the moving bracket 201, a driving slide 202b arranged on the moving bracket 201, a driving slider 202c arranged on the driving slider 202b, and a driving slide 202d opened on the moving bracket 201; wherein the driving slide 202d and the driving slider 202c are slidably connected.

[0045] Among them, the mobile bracket 201 is installed in the middle position of the main bracket 101, and its main function is to support the entire driving component 202 to ensure its stability and accuracy; the mobile slide groove 202a on the mobile bracket 201 is adapted to the driving slide 202b, which facilitates the sliding of the driving slide 202b. The driving slide 202b is installed on the mobile bracket 201 and adapted to the mobile slide groove 202a. Its function is to carry the driving slider 202c and drive the reflective diaphragm 103 to move by sliding. It matches the mobile slide groove 202a to ensure smooth sliding, and is fixedly connected to the driving slider 202c to ensure synchronous movement; the driving slide groove 202d is opposite It is said that it is arranged on both sides of the movable bracket 201, and the number of driving sliders 202c is four, and each two form a group. The driving slider 202c is fixedly connected to the driving slide 202b, and the driving slider 202c is installed under the driving slide 202b. The driving slide groove 202d is adapted to the driving slider 202c. By driving the driving slider 202c to slide in the driving slide groove 202d, a guide can be provided for the driving slide 202b during its movement, thereby avoiding position deviation of the driving slide 202b during its sliding process, thereby ensuring that the driving slide 202b moves with the reflecting diaphragm 103, so that the reflecting diaphragm 103 can better reflect light.

[0046] In this embodiment, the driving carriage 202b and the driving slider 202c are in the initial position, the reflective diaphragm 103 is in a stationary state, the driving carriage 202b is started by the electric motor power source, the driving carriage 202b slides along the moving slide groove 202a, and the driving slider 202c slides in the driving slide groove 202d, to ensure the smooth movement of the driving carriage 202b, the movement of the driving carriage 202b drives the reflective diaphragm 103 to move, to ensure that the reflective diaphragm 103 can reflect light more, and the position of the driving carriage 202b is adjusted by the control system 300 to ensure that the reflective diaphragm 103 is always in the best reflective position;

[0047] In summary, through this design, the driving assembly 202 can ensure the efficient movement and precise guidance of the reflective diaphragm 103, thereby improving the power generation efficiency of the photovoltaic panel of the double-glass assembly 102.

[0048] The cleaning assembly 203 includes a cleaning water tank 203a disposed on the mobile bracket 201, a flushing member 203b disposed on the cleaning water tank 203a, and a scraping member 203c disposed on the cleaning water tank 203a; the flushing member 203b includes a cleaning frame 203b-1 disposed on the cleaning water tank 203a, a cleaning water pipe 203b-2 disposed on the cleaning frame 203b-1, and a cleaning nozzle 203b-3 disposed on the cleaning water pipe 203b-2; the cleaning water pipes 203b-2 are grouped into two, which are respectively disposed on the cleaning water tank 203a and the cleaning water pipe 203b-2. At both ends of the box 203a, cleaning nozzles 203b-3 are arranged on the cleaning water pipe 203b-2, and the cleaning nozzles 203b-3 are arranged in an array; the scraper 203c includes a scraper bracket 203c-1 arranged on the movable bracket 201, and a scraper connecting plate 203c-2 arranged on the scraper bracket 203c-1; wherein, a torsion spring is arranged between the scraper bracket 203c-1 and the scraper connecting plate 203c-2; the scraper connecting plate 203c-2 is in the shape of an inverted "7", and both ends of the scraper connecting plate 203c-2 have a certain angle.

[0049] The cleaning water tank 203a is installed under the movable bracket 201 to store cleaning water and provide a water source for the flushing component 203b. It is usually made of corrosion-resistant materials such as stainless steel or plastic to ensure long-term use without damage.

[0050] The flushing member 203b is arranged on the cleaning water tank 203a, and flushes the surface of the reflective diaphragm 103 by spraying water to remove dust and stains; the cleaning connecting frame 203b-1 is fixed on the cleaning water tank 203a, and supports the cleaning water pipe 203b-2 and the cleaning nozzle 203b-3.

[0051] Multiple cleaning nozzles 203b-3 are arranged on each cleaning water pipe 203b-2 to form a straight line array. Usually, a pressure-resistant device is used, such as PVC or metal pipes. The cleaning nozzles 203b-3 are installed on the cleaning water pipe 203b-2 and arranged in a straight line array. After the spray mode is turned on, the spray angle and pressure can be adjusted to ensure full coverage of the surface of the reflective diaphragm 103. The cleaning nozzles 203b-3 are wear-resistant.

[0052] The scraping member 203c is disposed on the movable bracket 201 to further remove residual water marks and stains on the surface of the reflective film by physical scraping.

[0053] The scraping link 203c-2 is in the shape of an inverted "7" with a certain angle at both ends. The cross-sections of the two top corner blocks k and the protrusion j at the lower end are both triangular. When the scraping link 203c-2 moves along the direction of the tip block k, since the tip block k and the scraping link 203c-2 have a certain angle, the tip block k can clean the water stains on the reflective diaphragm 103. At the same time, during the return process of the scraping link 203c-2, the protrusion j cleans the water stains on the reflective diaphragm 103 again as it moves, thereby cleaning the reflective diaphragm 103. The torsion spring is arranged between the scraping bracket 203c-1 and the scraping link 203c-2. Its main function is to provide elastic force so that the scraping link 203c-2 is close to the surface of the reflective diaphragm 103 to ensure the scraping effect. High-strength spring steel is usually used to ensure that the elastic force is durable.

[0054] It should be noted that the scraping link 203c-2 is in the shape of an inverted "7", ensuring that the scraping link 203c-2 can cover the width of the reflective diaphragm 103 during movement, and the angle design at both ends enables it to better adapt to the surface of the reflective diaphragm 103. The two ends have a certain angle to ensure that the scraping link 203c-2 can better fit the surface of the reflective diaphragm 103 during movement, thereby improving the scraping effect. The triangular design enables the tip block k to effectively cut into the water stains and stains on the surface of the reflective diaphragm 103 during movement, thereby playing a role in preliminary cleaning. The protrusion j is located at the other end below the scraping link 203c-2, adjacent to the tip block k. The triangular design enables the protrusion j to further cut into the water stains and stains on the surface of the reflective diaphragm 103 during movement, thereby playing a role in secondary cleaning.

[0055] In this embodiment, the scraping link 203c-2, the tip block k and the protrusion j are in the initial position, ready to start the scraping operation. When the scraping link 203c-2 moves along the direction of the tip block k, the angle between the tip block k and the scraping link 203c-2 enables the tip block k to cut into the water stains and stains on the surface of the reflective film for preliminary scraping. The triangular cross-section of the tip block k cuts into the surface of the reflective diaphragm 103 to push the water stains and stains away. The lower surface of the scraping link 203c-2 is in close contact with the reflective diaphragm 103 to further push the water stains and stains. When the scraping link 203c-2 moves during the return process, the protrusion j cleans the water stains and stains on the reflective diaphragm 103 again as it moves. The triangular cross-section of the protrusion j cuts into the surface of the reflective diaphragm 103 again to further remove the residual water stains and stains. The lower surface of the scraping link 203c-2 continues to be in close contact with the reflective diaphragm 103 to ensure cleaning.

[0056] In summary, the design of the flushing member 203 b and the scraping member 203 c can ensure efficient cleaning of the surface of the reflective diaphragm 103 and maintain its high reflectivity, thereby improving the power generation efficiency of the photovoltaic panel of the double-glass assembly 102 .

[0057] The rest of the structure is the same as that of Example 1.

[0058] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the recovery component 204 includes a recovery baffle 204a arranged on the cleaning water tank 203a, a recovery slot 204b opened on the recovery baffle 204a, and a filter element 204c arranged in the recovery slot 204b; the filter element 204c includes a filter bracket 204c-1 arranged in the recovery slot 204b, and a filter net bag 204c-2 arranged on the filter bracket 204c-1.

[0059] Among them, the recovery baffle 204a is set on the cleaning water tank 203a, and its main function is to prevent the cleaned water and stains from directly flowing into the recovery system, and guide the water flow into the recovery slot 204b, which is usually slightly inclined at both ends to ensure normal water flow. The recovery slot 204b is opened at both ends of the recovery baffle 204a, and its function is to guide the cleaned water and stains to flow into the filter element 204c for preliminary filtration. An inclined chute m is set on one side of the recovery slot 204b to prevent excessive impact of the water flow and damage to the filter element 204c.

[0060] The filter element 204c is arranged at the lower part of the recovery tank, and its function is to filter the cleaned water, recycle rainwater, remove stains and impurities in the water, and ensure the cleanliness of the recycled water.

[0061] The filter bracket 204c-1 is set in the recovery slot 204b to support the filter net bag 204c-2. It is usually a frame structure to ensure that the filter net bag 204c-2 can be firmly installed. The filter net bag 204c-2 usually adopts a fine filter net to ensure effective filtering of stains and impurities in the water.

[0062] In this embodiment, in the initial position, the recovery baffle 204a is installed on the cleaning water tank 203a, the recovery slot 204b is opened at both ends of the recovery baffle 204a, and the filter element 204c is embedded in the recovery slot. The cleaned water and substances flow into the recovery slot 204b through the influence of the recovery baffle 204a, and the water flows through the filter net bag 204c-2 of the filter element 204c. The filter net bag 204c-2 captures stains and impurities in the water to ensure the cleanliness of the recovered water. The filtered water source flows into the recovery system and can be used for cleaning or discharge again.

[0063] In summary, through the above design, the recovery component 204 can ensure that the water source after cleaning is effectively filtered and recovered, reduce the waste of water resources, and improve the overall efficiency of the system.

[0064] The rest of the structure is the same as that of Example 3.

[0065] Example 4, reference Fig. 9 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that:

[0066] The control system 300 includes a moving module 301, a self-cleaning module 302, a sensor module 303, and a timing module 304;

[0067] The moving module 301 is used to control the sliding on the driving slide 202b, the self-cleaning module 302 is installed on the moving bracket 201, the sensor module 303 is connected to the self-cleaning module 302, and the timing module 304 is connected to the self-cleaning module 302.

[0068] Among them, the function of the moving module 301 is to ensure that the reflective diaphragm 103 can be moved to the optimal position as needed, maximize the utilization of light, and provide power for the moving components. The self-cleaning module 302 is used to regularly clean the surface of the reflective film to maintain its high reflectivity and improve the power generation efficiency of the photovoltaic panel. The sensor module 303 mainly realizes intelligent cleaning by monitoring the degree of dirt on the surface of the reflective diaphragm 103 and the ambient humidity and other information. The timing module 304 can automatically start and stop the self-cleaning module 302 at a preset time interval.

[0069] The rest of the structure is the same as that of Example 2.

[0070] Additionally, in order to provide a concise description of exemplary embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
