In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0040] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0042] Photovoltaic panels are the main components of solar power generation systems. After being laid on photovoltaic brackets, they are used to capture sunlight and convert light into electricity. In the daily operation of photovoltaic power plants, natural dust and industrial smoke in the environment will be deposited on the surface of photovoltaic panels; statistical analysis shows that the particle diameter of the above-mentioned sediments is generally between one hundredth of a millimeter and several hundredths of a millimeter, and the chemical composition is mainly solid oxides such as SiO2, Al2O3, Fe2O3, Na2O, CaO, and liquid oil droplets, among which the content of SiO2 and Al2O3 is as high as 68% to 76% and 10% to 15% (Review of Research on Dust Accumulation and Dust Removal and Cleaning Technology of Photovoltaic Panels, Mechanical and Electrical Engineering, Vol. 30, No. 8, DOI: 10.3969 / j.issn.1001-4551.2013.08.003).

[0043] In order to reduce the shading of sunlight to the panels by the above-mentioned sediments and thus ensure the capture-photovoltaic conversion efficiency, large-scale photovoltaic fields generally adopt the following measures for comprehensive control: First, in the design of photovoltaic panels, measures such as smooth treatment of the surface glass and self-cleaning coating (Self-cleaning Glass for Solar Photovoltaics SJ / T11800-2022) are introduced to reduce the adhesion of dust / smoke particles and improve self-cleaning ability; second, in the design of photovoltaic brackets, the rainfall and light angle are comprehensively considered, and the laying inclination angle of the photovoltaic panels is optimized to maintain effective natural cleaning ability by balancing the power generation efficiency and the rain flushing effect; third, in the operation and maintenance link, manual or mechanical cleaning is carried out by artificial means such as (softened water + cleaning agent) mixed spraying, brush scraping, air blowing, etc.

[0044] Among the above methods, the tempering, polishing and coating of the surface glass will increase the manufacturing cost, the optimization of the photovoltaic panel laying inclination angle will restrict the power generation efficiency, and the comprehensive benefits of brush cleaning + air blowing are significant. In recent years, a complete photovoltaic panel brush cleaning technology system has been developed at home and abroad, covering the cleaning robot system, brush configuration, brush handle, brush bundle / single filament material, drive mechanism control and cleaning agent.

[0045] However, the reciprocating dynamic contact between the brush filaments and the panel surface will entrain high-hardness particles such as SiO2 and Al2O3; as the core materials of traditional industrial abrasives and drill tools, SiO2, Al2O3 and other particles will cause scratches, pits and other tiny mechanical wear to the surface glass under certain contact extrusion pressure and relative speed conditions, eventually forming a roughened shading effect and seriously affecting the power generation efficiency in an irreversible state.

[0046] At present, the industry is working on the two major effects of chemical descaling of cleaning fluids (for organic pollutants) and mechanical scraping of brushes (for solid particles). On the one hand, we focus on the balance between descaling efficiency and environmental pollution, improve the chemical composition of cleaning agents and reduce the quality and amount of softened water; on the other hand, we study the cleaning efficiency under different motion parameters for the surface roughness after sediment attachment (the original glass surface roughness superimposed on the particle accumulation effect) and panel configuration (grooves, joints, corners between panels, etc.), and develop single-filament materials such as PBT, nylon, and PE as well as filament forming process technology. The disadvantage is that the stiffness of the filament bundle is limited by the material formula and synthesis process of the brush wire, and can only be controlled by the driving mechanism of the cleaning robot system to adapt to the matching requirements between the moving speed, contact extrusion force, and filament bundle hardness and abrasion degree. The control is complex and the operation is cumbersome.

[0047] In response to the above-mentioned technical problems, the embodiments of the present application provide a photovoltaic panel cleaning method, device, electronic device and storage medium, which achieve on-demand adjustment of the bundle stiffness by precisely designing the structure and parameters of the composite bundle to adapt to different cleaning equipment and different panels to be cleaned, thereby achieving efficient cleaning of the photovoltaic panel and avoiding damage to the photovoltaic panel, thereby improving the operating efficiency of the solar power generation system.

[0048] See also Figure 1 , Figure 1 : is a flow chart of a photovoltaic panel cleaning method provided in an embodiment of the present application. The photovoltaic panel cleaning method provided in this embodiment may specifically include the following steps:

[0049] S1. Obtaining the motion parameters of the cleaning equipment and the material characteristic parameters of the photovoltaic panel to be cleaned;

[0050] Specifically, for step S1, the main purpose is to obtain the motion parameters of the cleaning equipment required for this cleaning task and the material characteristic parameters of the photovoltaic panel to be cleaned, wherein the motion parameters of the cleaning equipment include the motion speed and the clamping force per unit area, which determine the strength and speed of the contact between the brush and the photovoltaic panel during the cleaning process; the material characteristic parameters of the photovoltaic panel include the surface roughness index and the breaking strength of the protective glass, which affect the selection of the cleaning strategy and the design of the cleaning tools.

[0051] S2. Determine the target stiffness parameter of the composite tow based on the motion parameter and the material characteristic parameter;

[0052] Specifically, for step S2, a preset formula is used to calculate the cleaning factor, which comprehensively considers the movement speed, compression force, surface roughness and breaking strength to determine the target stiffness of the composite filament bundle; the target stiffness parameters include the single filament diameter, the brush bundle diameter and the distance between adjacent brush bundles, and these stiffness parameters directly affect the cleaning effect and the safety of the photovoltaic panel.

[0053] S3. adjusting the stiffness parameter of the composite tow to the target stiffness parameter;

[0054] Specifically, for step S3, the structure of the composite tow is adjusted according to the calculated target stiffness parameter to adapt to different cleaning requirements and characteristics of the photovoltaic panel.

[0055] S4. Controlling the cleaning equipment to clean the surface of the photovoltaic panel to be cleaned through the adjusted composite tow;

[0056] Specifically, for step S4, the cleaning equipment is controlled to use the adjusted composite filament bundle to clean the surface of the photovoltaic panel, ensuring that the cleaning process is both effective and does not damage the photovoltaic panel.

[0057] The specific cleaning process is as follows: install the adjusted composite filament bundle on the cleaning equipment to ensure good contact between the filament bundle and the surface of the photovoltaic panel; start the cleaning equipment, control its movement speed and pressing force to ensure that it matches the stiffness parameters of the composite filament bundle; the cleaning equipment moves according to a predetermined path and pattern, and uses the composite filament bundle to clean the surface of the photovoltaic panel.

[0058] During the cleaning process, the cleaning effect and the status of the photovoltaic panel are monitored in real time to ensure that no damage occurs; if necessary, the cleaning parameters or tow structure are adjusted based on the feedback to optimize the cleaning effect.

[0059] After cleaning, evaluate the cleanliness of the photovoltaic panel surface to ensure that the expected cleaning effect is achieved; if necessary, perform additional cleaning or adjust the cleaning strategy. After cleaning, perform necessary maintenance and adjustments on the cleaning equipment and composite tow to maintain their optimal performance.

[0060] In addition, all parameters and effects of the cleaning process can be recorded and data analyzed to facilitate continuous improvement of the cleaning method.

[0061] It can be seen that the photovoltaic panel cleaning method provided in this embodiment can more effectively remove dirt on the surface of the photovoltaic panel and improve the cleaning efficiency by accurately matching the motion parameters of the cleaning equipment and the material properties of the photovoltaic panel; by calculating the cleaning factor and adjusting the filament bundle stiffness, it can clean without damaging the photovoltaic panel and extend the service life of the photovoltaic panel; it can flexibly adjust the cleaning strategy according to the characteristics of different photovoltaic panels and the conditions of the cleaning equipment, and has good adaptability.

[0062] Furthermore, in some embodiments, step S1 of "obtaining motion parameters of the cleaning device and material characteristic parameters of the photovoltaic panel to be cleaned" may specifically include:

[0063] S11 obtains the movement speed and the pressing force per unit area of ​​the cleaning equipment;

[0064] S12. Obtaining a roughness index of the surface of the photovoltaic panel to be cleaned and a fracture strength of a protective glass of the photovoltaic panel to be cleaned.

[0065] Specifically, for step S1, the movement parameters of the cleaning equipment may include the movement speed of the cleaning equipment and the pressing force per unit area, wherein the movement speed of the cleaning equipment affects the cleaning efficiency and contact strength, and a speed that is too fast may result in incomplete cleaning, while a speed that is too slow may affect the cleaning efficiency; the pressing force per unit area determines the degree of contact between the brush and the photovoltaic panel, affecting the cleaning effect and the safety of the panel. The material characteristic parameters of the photovoltaic panel to be cleaned may include the roughness index of the surface of the photovoltaic panel to be cleaned and the fracture strength of the protective glass of the photovoltaic panel to be cleaned; wherein the surface roughness index of the photovoltaic panel surface directly affects the difficulty of cleaning and the required cleaning strength; the fracture strength of the protective glass is an important consideration when designing the cleaning strength to avoid damage during the cleaning process.

[0066] In a specific embodiment, the movement speed and pressing force of the cleaning equipment can be obtained by the sensor of the cleaning equipment or the standard test method; the surface roughness of the photovoltaic panel to be cleaned can be measured by a surface roughness measuring instrument, such as a profilometer or a roughness meter; the fracture strength of the protective glass can be obtained by material testing, such as a three-point bending test or an impact test. The above parameters can also be determined according to the technical parameters and design requirements of the cleaning equipment, or evaluated according to the specifications or historical data provided by the photovoltaic panel manufacturer, or refer to the technical specifications or material safety data sheet provided by the protective glass manufacturer.

[0067] By accurately obtaining parameters, this embodiment can ensure a more accurate match between the cleaning equipment and the photovoltaic panel, thereby improving cleaning efficiency and safety; according to the characteristics of different photovoltaic panels and the conditions of the cleaning equipment, a personalized cleaning plan can be formulated to improve the adaptability and effect of cleaning; accurately understanding the breaking strength of the protective glass can avoid excessive pressure when designing the cleaning force, reducing the risk of damage to the photovoltaic panel; adjusting the cleaning force and bundle stiffness according to the surface roughness can more effectively remove dirt and improve the cleaning quality; through reasonable cleaning force and bundle stiffness, the wear on the photovoltaic panel can be reduced and its service life can be extended.

[0068] Further, in some embodiments, step S2 of “determining a target stiffness parameter of the composite tow based on the motion parameter and the material characteristic parameter” may specifically include:

[0069] S21. Calculate the corresponding cleaning factor based on the motion parameters and material characteristic parameters by a preset formula;

[0070] S22. Based on the cleaning factor, the target stiffness parameters corresponding to the composite filament bundle are calculated, wherein the target stiffness parameters include the single filament diameter, the brush bundle diameter and the distance between adjacent brush bundles.

[0071] Specifically, for determining the target stiffness parameters of the composite filament bundle in step S2, a preset formula is mainly used to calculate the cleaning factor. The cleaning factor comprehensively considers the movement speed of the cleaning equipment, the pressing force per unit area, the roughness index of the photovoltaic panel surface and the breaking strength of the protective glass. Based on the cleaning factor, the target stiffness parameters of the composite filament bundle are further calculated. The target stiffness parameters may specifically include single filament diameter, brush bundle diameter and adjacent brush bundle distance, etc. These parameters directly affect the performance and cleaning effect of the cleaning tool.

[0072] Furthermore, in some embodiments, the preset formula is:

[0073] λ=log(v / Ra)+log(б / P);

[0074] In the formula, λ is the cleaning factor, v is the movement speed of the cleaning equipment, and the unit is meter per second; P is the movement speed of the cleaning equipment and the pressing force per unit area, and the unit is megapascal; Ra is the roughness index of the surface of the photovoltaic panel to be cleaned; б is the breaking strength of the protective glass of the photovoltaic panel to be cleaned, and the unit is megapascal.

[0075] Among them, after calculating the cleaning factor, the diameters of two types of monofilaments (including central monofilaments and edge monofilaments) are calculated respectively, r = λ × 0.01, r is taken in millimeters, and 2 significant digits are retained; the diameter of the brush bundle is calculated R = λ × 2.0, R is taken in millimeters, and 1 significant digit is retained; the distance between adjacent brush bundles is calculated d = int (2.0 × R), d is taken in millimeters, and 1 significant digit is retained.

[0076] Through the calculation of the cleaning factor, this embodiment can accurately match the stiffness of the composite filament bundle to ensure efficient cleaning without damaging the photovoltaic panel; the determined target stiffness parameter enables the composite filament bundle to adapt to different cleaning conditions, optimize the cleaning effect, and improve the cleanliness of the photovoltaic panel; by considering the breaking strength of the protective glass, excessive mechanical stress on the photovoltaic panel during the cleaning process can be avoided, and the panel can be protected from damage; flexible adjustment according to the specific characteristics of the photovoltaic panel and the conditions of the cleaning equipment enhances the adaptability of the cleaning method; by reducing damage to the photovoltaic panel, its service life is extended, thereby reducing maintenance and replacement costs; the cleaned photovoltaic panel can more effectively convert solar energy and improve the energy utilization efficiency of the entire solar power generation system; the method helps to improve the sustainability and environmental friendliness of photovoltaic energy by improving cleaning efficiency and reducing damage.

[0077] Furthermore, in some embodiments, the composite filament bundle provided in this embodiment includes a plurality of evenly arranged brush bundle units, and the distances between adjacent brush bundle units are equal.

[0078] Specifically, Figure 2 As shown, the composite filament bundle in this embodiment is composed of a number of evenly arranged brush bundle units, the design of which ensures the uniformity and efficiency of the cleaning process. The distances between adjacent brush bundle units are equal, which helps to achieve full coverage of the entire photovoltaic panel surface and avoid blind areas in cleaning.

[0079] The evenly arranged brush bundle units designed in this embodiment can provide consistent cleaning pressure and contact, thereby improving the consistency and thoroughness of cleaning; by ensuring that the distances between the brush bundle units are equal, the cleaning path can be optimized and the possibility of repeated cleaning or missed areas can be reduced.

[0080] Further, in some embodiments, the brush bundle unit provided in this embodiment includes 9 monofilaments arranged in a 3x3 array, wherein 1 monofilament is a central monofilament and 8 monofilaments are edge monofilaments.

[0081] Specifically, Figure 2 As shown, each brush unit includes 9 filaments arranged in a 3x3 array, which provides sufficient cleaning coverage while maintaining the compactness of the brush unit. The different layouts of the center filaments and the edge filaments help achieve a more detailed cleaning effect.

[0082] The 3x3 array layout designed in this embodiment provides a larger contact area, which helps to improve the cleaning efficiency; the coordinated work of the center filaments and the edge filaments can more effectively remove dirt on the surface of the photovoltaic panel.

[0083] Furthermore, in some embodiments, the central monofilament provided in this embodiment is made of PBT material monofilament, and the edge monofilament is made of PE material monofilament.

[0084] Specifically, the central monofilament in the brush bundle unit is made of PBT (polybutylene terephthalate) material monofilament, and the edge monofilament is made of PE (polyethylene) material monofilament. PBT is suitable as the central monofilament due to its higher modulus and wear resistance, providing structural support and decontamination ability; while PE is suitable as the edge monofilament due to its good flexibility and cost-effectiveness, so as to adapt to the irregularities of the photovoltaic panel surface and reduce potential damage to the panel.

[0085] The PBT center monofilament in this embodiment provides the required stiffness and wear resistance, ensuring durability and decontamination effect during the cleaning process; the flexibility of the PE edge monofilament helps to protect the surface of the photovoltaic panel and avoid scratches or damage during the cleaning process; the differentiated selection of materials enables the composite filament bundle to adapt to different cleaning conditions and photovoltaic panel surface characteristics, thereby improving the adaptability and effectiveness of the cleaning method.

[0086] In a specific embodiment, the composite filament bundle in this embodiment is made of PBT and PE monofilaments, which are a combination of monofilaments of different diameters and different materials. Nine monofilaments constitute a basic unit and are arranged in an array. Inside the basic unit, one PBT monofilament with a larger modulus is used as the central monofilament, and eight PE monofilaments with a smaller stiffness are used as the edge monofilaments. The diameters of the two types of monofilaments are both r. Among them, several groups of basic units are evenly arranged into a brush bundle with a diameter of R and arranged on the brush handle.

[0087] In summary, the photovoltaic panel cleaning method provided in this embodiment first obtains the motion parameters of the cleaning device and the material characteristic parameters of the photovoltaic panel to be cleaned; then, based on the motion parameters and the material characteristic parameters, determines the target stiffness parameters of the composite filament bundle; then, adjusts the stiffness parameters of the composite filament bundle to the target stiffness parameters; finally, controls the cleaning device to clean the surface of the photovoltaic panel to be cleaned through the adjusted composite filament bundle. It can be seen that this embodiment can more effectively remove dirt on the surface of the photovoltaic panel and improve the cleaning efficiency by accurately matching the motion parameters of the cleaning device and the material characteristics of the photovoltaic panel; by calculating the cleaning factor and adjusting the stiffness of the filament bundle, it can clean without damaging the photovoltaic panel and extend the service life of the photovoltaic panel; it can flexibly adjust the cleaning strategy according to the characteristics of different photovoltaic panels and the conditions of the cleaning equipment, and has good adaptability.
