[0038] As described in the background art, in the related art, manual cleaning is usually adopted. However, for photovoltaic panels installed in complex terrains or high-altitude areas, manual cleaning may be inconvenient, resulting in low cleaning efficiency. In addition, due to the large area of the photovoltaic panels, manual cleaning may result in uneven cleaning, leading to poor cleaning effects in some areas.

[0039] In view of the above technical problems, an embodiment of the present application provides a photovoltaic panel cleaning device, including a cleaning component, a guide rail component, and a driving component. The guide rail component includes a horizontal guide rail and a vertical guide rail. The horizontal guide rail is located on one side of the photovoltaic panel, and the vertical guide rail is passed through the horizontal guide rail, so that the vertical guide rail can slide on the horizontal guide rail. By arranging the cleaning component on the vertical guide rail, when the vertical guide rail slides, the cleaning component can perform horizontal cleaning on the photovoltaic panel. In addition, the cleaning component is slidably connected to the vertical guide rail, so the cleaning component can also perform vertical cleaning on the photovoltaic panel. During this process, the driving component

[0043] Please refer to Figures 1 to 4 , Figure 1 which is a schematic structural diagram of the photovoltaic panel cleaning device provided by the embodiment of the present application; Figure 2 which is a schematic structural diagram of another photovoltaic panel cleaning device provided by the embodiment of the present application;

[0044] Figure 3 which is a schematic diagram of another operating state of the photovoltaic panel cleaning device provided by the embodiment of the present application; Figure 4 which is a partial cross-sectional view of the photovoltaic panel cleaning device provided by the embodiment of the present application.

[0045] Please refer to Figure 1An embodiment of the present application provides a photovoltaic panel cleaning device, including: a cleaning component 2, a guide rail component and a drive component. The cleaning component 2 is used to clean the upper surface of the photovoltaic panel 1. The guide rail component facilitates the movement of the cleaning component 2 on the photovoltaic panel 1. The drive component is used to control the cleaning component 2.

[0046] The guide rail assembly includes a transverse guide rail 12 and a longitudinal guide rail 11. The guide rail assembly is arranged on the upper surface of the photovoltaic panel 1. The transverse guide rail 12 is arranged on one side of the photovoltaic panel 1. The longitudinal guide rail 11 is passed through the transverse guide rail 12 and is slidably connected to the transverse guide rail 12. With such an arrangement, the longitudinal guide rail 11 can slide on the transverse guide rail 12. During the transverse sliding process, the body of the longitudinal guide rail 11 can cover the entire upper surface of the photovoltaic panel 1. Through the combination of the transverse guide rail 12 and the longitudinal guide rail 11, the cleaning assembly can move in both directions on the surface of the photovoltaic panel 1, thereby improving the cleaning coverage and efficiency.

[0047] In this embodiment, the guide rail assembly can be adjusted according to the size of the photovoltaic panel 1, and both the transverse guide rail 12 and the longitudinal guide rail 11 can be made of lightweight and corrosion-resistant materials, such as aluminum alloy.

[0048] The cleaning component 2 is arranged on the longitudinal guide rail 11 and is slidably connected to the longitudinal guide rail 11. With such an arrangement, the cleaning component 2 can slide longitudinally on the longitudinal guide rail 11. Thus, when the longitudinal guide rail 11 slides transversely on the transverse guide rail 12, the cleaning component 2 can synchronously slide longitudinally on the longitudinal guide rail 11, thereby comprehensively cleaning the photovoltaic panel 1. The sliding connection design between the transverse guide rail 12 and the longitudinal guide rail 11, and the longitudinal guide rail 11 and the cleaning component allows the cleaning component to be flexibly moved to adapt to photovoltaic panels of different sizes and shapes.

[0049] As an example, the cleaning component 2 may include a brush, a detergent device and a recovery device, wherein the brush is used to physically clean the upper surface of the photovoltaic panel 1, the detergent device is used to spray detergent or water to assist cleaning, and the recovery device is used to recover the sewage absorbed during the cleaning process. The brush, detergent device and recovery device can be used individually or in combination as needed.

[0050] Furthermore, the cleaning component 2 may be a replaceable multifunctional cleaning head, which can be easily replaced with different types of brushes, scrapers or nozzles according to different cleaning needs to adapt to different pollution conditions and cleaning requirements.

[0051] In this embodiment, rollers or sliders may be provided at the connection between the transverse guide rail 12 and the longitudinal guide rail 11 to reduce friction and ensure smooth movement of the cleaning assembly 2 .

[0052] The driving component is arranged on the cleaning component 2 and is used to control the movement of the cleaning component 2, ensuring that the movement of the cleaning component 2 does not deviate from the guide rail component and always remains on the upper surface of the photovoltaic panel 1. By integrating the driving component on the cleaning component, the movement of the cleaning component can be directly controlled, realizing automatic cleaning, simplifying the structure of the entire device, and improving reliability.

[0053] As an example, the driving component may include a motor, gears, and a belt. The motor drives the cleaning component to move along the longitudinal guide rail 11 through the gears and the belt. The control of the motor can be achieved through a preset program or remote control, so as to perform timed or quantitative cleaning according to the cleaning requirements of the photovoltaic panel 1. In this embodiment, the driving component may be the driving motor 18.

[0054] As another example, the driving component is a solar energy device, such as a small solar panel and an energy storage device, which is used to provide energy. In this way, the energy self - sufficiency of the cleaning device can be realized, reducing the dependence on external power supplies.

[0055] In this embodiment, through the modular design of the cleaning component, the guide rail component, and the driving component, the installation, maintenance, and replacement of the photovoltaic panel cleaning device of the present application are more convenient, reducing the overall cost.

[0056] In some embodiments, the photovoltaic panel cleaning device further includes a protection device, including a dust cover and a waterproof cover, which are used to protect the cleaning component 2 and the guide rail component in a non - working state, preventing erosion by dust and rain.

[0057] The photovoltaic panel cleaning device provided by the embodiment of the present application is provided with a guide rail component on the upper surface of the photovoltaic panel 1, facilitating the movement of the cleaning component 2 on the photovoltaic panel 1 for the cleaning process. By arranging the transverse guide rail 12 on one side of the photovoltaic panel 1 and threading the longitudinal guide rail 11 through the transverse guide rail 12 for sliding, it is convenient for the cleaning component 2 to clean the entire photovoltaic panel 1 more comprehensively, improving the cleaning coverage rate, avoiding sanitary dead corners, ensuring thorough and uniform cleaning. At the same time, this cleaning process is driven and controlled by the driving component, reducing manual intervention and realizing intelligent and automatic cleaning.

[0058] Please refer to Figure 2 , in order to prevent the longitudinal guide rail 11 from possibly detaching from the transverse guide rail 12 when sliding on the transverse guide rail 12, in a possible implementation manner, fixing members 15 are provided at both ends of the transverse guide rail 12 for restricting the sliding of the longitudinal guide rail 11.

[0059] Furthermore, elastic buffer devices can be added at the relative positions of the fixing members 15 at both ends of the transverse guide rail 12 to reduce the impact force when the sliding ring 16 moves to the end of the guide rail, extending the service life of the device. Among them, the elastic buffer device can be made of materials such as rubber pads.

[0060] A sliding ring 16 is provided on the transverse guide rail 12, and one end of the longitudinal guide rail 11 is fixedly connected to the sliding ring 16, thereby improving the sliding efficiency of the longitudinal guide rail 11 and preventing large friction from occurring, which may affect the cleaning process.

[0061] It should be noted that the fixed connection between one end of the longitudinal guide rail 11 and the sliding ring 16 can be achieved by means such as welding, riveting, and bolt connection. This embodiment does not limit this here, ensuring that when the sliding ring 16 moves, it can drive the longitudinal guide rail 11 to move synchronously and ensuring high stability and the ability to withstand high loads.

[0062] Exemplarily, the contact surface between the sliding ring 16 and the transverse guide rail 12 has a lubricating coating or ball bearings to reduce friction and improve the moving efficiency of the longitudinal guide rail 11. The lubricating coating can be any low-friction material, and this embodiment does not limit this here.

[0063] Furthermore, a locking mechanism can be added to the sliding ring 16, enabling the sliding ring 16 to be fixed at any position on the transverse guide rail 12. With this setting, when there are difficult-to-remove stains at a certain position on the surface of the photovoltaic panel 1, the sliding ring 16 can be locked, thereby fixing the longitudinal guide rail 11 and enabling the cleaning component 2 on the longitudinal guide rail 11 to perform targeted cleaning. Among them, the locking mechanism can adopt a manual locking bolt or an automatic locking device for use under different operating conditions.

[0064] In some embodiments, sensors can be integrated on the sliding ring 16 for real-time monitoring of the position and moving speed of the sliding ring 16. Among them, the sensors can be optoelectronic sensors, magnetic sensors, laser sensors, etc., which are electrically connected to the driving component, thereby enabling the cleaning process to be controllable and further improving the cleaning efficiency.

[0065] Please continue to refer to Figure 2 , in this embodiment, a bracket assembly can also be included for fixing and supporting the photovoltaic panel 1, while enhancing the stability of the photovoltaic panel cleaning device provided in this application.

[0066] The bracket assembly includes a fixed frame 13 and a connecting housing 14. The connecting housing 14 is provided on both sides of the photovoltaic panel 1, and one side of the connecting housing 14 is fixedly connected to the fixing member 15, that is, the connecting housing 14 clamps on both sides of the photovoltaic panel 1, which can prevent the photovoltaic panel 1 from moving or slipping during the cleaning process. The fixed frame 13 is fixedly connected to the connecting housing 14, which can provide support, effectively resist external forces, ensure that the guide rail assembly and the cleaning component 2 can be stably installed and operated, and prevent shaking or displacement during the cleaning process, thereby improving the cleaning effect and the safety of the cleaning device.

[0067] It should be noted that the connection between the outer shell 14 and the fixing member 15 can be achieved by magnetic attraction or adhesive, making it convenient for installation and disassembly.

[0068] The bracket assembly is made of high-strength and corrosion-resistant materials such as stainless steel and aluminum alloy, and can be used for a long time in various harsh environments, thereby enhancing the durability of the entire device.

[0069] Furthermore, the fixing frame 13 and the photovoltaic panel 1 are inclined, which can make the photovoltaic panel 1 inclined to the ground. Since the inclination angle of the photovoltaic panel 1 directly affects its sunlight capture efficiency, by setting the photovoltaic panel 1 at a specific angle through the fixing frame 13, the amount of solar radiation received on the surface of the photovoltaic panel 1 can be maximized, thereby improving the power generation efficiency. Among them, the specific inclination angle is usually adjusted according to the geographical location and seasonal changes. In addition, the inclination of the photovoltaic panel 1 helps the natural sliding of rainwater and dust, reduces the accumulation of dust and dirt on the surface of the photovoltaic panel 1, has a self-cleaning effect, can reduce the cleaning frequency, lower the maintenance cost, and maintain the high-efficiency working state of the photovoltaic panel 1 at the same time.

[0070] In some embodiments, the height of the bracket assembly is adjustable. The fixing frame 13 and the connection outer shell 14 are connected by a telescopic support rod, and the support rod can be adjusted in height manually or electrically to meet the installation requirements of different photovoltaic panels 1.

[0071] Another photovoltaic panel cleaning device provided by the embodiment of the present application can improve the stability of the entire cleaning device by setting fixing members 15 at both ends of the transverse guide rail 12 to fixedly connect the longitudinal guide rail 11 and the sliding ring 16, and further set a fixing frame 13 inclined to the photovoltaic panel 1 by fixedly connecting the fixing member 15 and the connection outer shell 14, so as to achieve a self-cleaning effect and prevent shaking or displacement during the cleaning process, thereby improving the cleaning effect and the safety of the cleaning device.

[0072] Please refer to Figure 1 and Figure 3 , in a possible implementation manner, the cleaning component may include a cleaning plate 21 and a sliding member 23;

[0073] The cleaning plate 21 is arranged on the upper surface of the photovoltaic panel 1 and is always in close contact with the surface of the photovoltaic panel 1 to ensure the cleaning effect.

[0074] The sliding member 23 is sleeved on the longitudinal guide rail 11 and is fixedly connected to the cleaning plate 21, so that the sliding of the sliding member 23 drives the cleaning plate 21 to move synchronously, achieving a comprehensive cleaning effect.

[0075] Through modular design, the cleaning plate 21 is used to clean the photovoltaic panel 1, while the sliding member 23 is used to move the cleaning plate 21. The cleaning plate 21 and the sliding member 23 can be replaced as needed. For example, the cleaning plate 21 can be replaced with different materials according to actual needs, such as soft brushes, hard brushes, scrapers, sponges, etc., to adapt to different dirt types and cleaning requirements. At the same time, the sliding member 23 can be adjusted and replaced according to the sizes of different photovoltaic panels 1 and the specifications of different guide rail assemblies to meet different installation requirements. Further, lubricant can be added to the contact part of the sliding member 23 with the longitudinal guide rail 11 to reduce friction and wear and ensure the long-term stable operation of the cleaning assembly.

[0076] As an example, the shape of the contact surface between the cleaning plate 21 and the photovoltaic panel 1 is a polygon with an arc-shaped inner corner. With such a setting, the arc-shaped inner corner can better fit the surface of the photovoltaic panel 1, especially at the edges and corners of the photovoltaic panel 1. For example, the traditional right-angle design may leave dead corners during the cleaning process, while the arc-shaped inner corner can effectively cover these areas to ensure the entire surface of the photovoltaic panel is comprehensively cleaned. On the other hand, it can reduce the friction and wear between the cleaning plate 21 and the surface of the photovoltaic panel 1, extend the service life of the photovoltaic panel and the cleaning plate, and at the same time make the cleaning plate 21 move more smoothly during the movement, reduce jamming and resistance, thereby improving the cleaning efficiency.

[0077] Please refer to Figure 3 and Figure 4 In a possible implementation manner, the cleaning assembly 2 may further include a rotating shaft 22, a limiting member 24, and a connecting member 25. The driving assembly drives the rotating shaft 22 so that one end of the rotating shaft 22 is fixedly connected to the connecting member 25 and the other end can rotate. When the driving assembly drives the rotating shaft 22 to rotate, it drives the cleaning plate 21 to move on the longitudinal guide rail 11, so that the cleaning plate 21 moves on the photovoltaic panel 1 to achieve the cleaning effect. Further, it drives the longitudinal guide rail 11 to move on the transverse guide rail 12, so that the cleaning trajectory of the cleaning plate is a regular quadrilateral, ensuring that the cleaning plate can clean more comprehensively and avoiding dead corners.

[0078] By fixedly connecting the limiting member 24 to the end of the sliding member 23 away from the cleaning plate 21, a fulcrum can be provided for the rotation of the rotating shaft 22, restricting the rotation range of the rotating shaft 22 to ensure that the rotation of the rotating shaft 22 does not exceed the maximum rotation angle limit and preventing damage to the cleaning assembly 2.

[0079] In some embodiments, the limiting member 24 may also be a structure with a locking function, such as a mechanical lock or an electromagnetic lock, etc., so that the limiting member 24 can be automatically locked when the cleaning plate 21 reaches a predetermined position, preventing the rotating shaft 22 from rotating and preventing the cleaning plate 21 from displacing during the cleaning process to ensure the cleaning effect.

[0080] The rotating shaft 22 is movably connected to the sliding member 23, and a connecting member 25 is fixedly connected to one end of the rotating shaft 22 that is movably connected to the sliding member 23. The connecting member 25 is sleeved outside the limiting member 24, thereby connecting the rotating shaft 22 and the limiting member 24 to ensure stable connection between the components.

[0081] In this embodiment, through the cooperative action of the rotating shaft 22, the limiting member 24, and the connecting member 25, the cleaning plate 21 can flexibly adjust its angle and position to ensure comprehensive cleaning of the surface of the photovoltaic panel 1, improve the cleaning efficiency. At the same time, each component can be disassembled, facilitating the replacement and maintenance of the components, thereby improving the maintainability and service life of the photovoltaic panel cleaning device.

[0082] The photovoltaic panel cleaning device provided by the embodiment of the present application can achieve comprehensive cleaning of the photovoltaic panel 1 through the combined action of multiple components including the cleaning plate 21, the sliding member 23, the rotating shaft 22, the limiting member 24, and the connecting member 25, improving the cleaning effect and further enhancing the cleaning efficiency.

[0083] Please refer to Figure 1 、 Figure 3 and Figure 4 , in a possible implementation manner, the driving component further includes a driving shaft 17 and a fixing block 26. The driving shaft 17 is a key component connecting the driving motor 18 and the fixing block 26, used to transmit the power of the driving motor 18 to the fixing block 26, thereby driving the movement of the cleaning component 2. The fixing block 26 is sleeved on the rotating shaft 22, used to ensure the stable connection between the rotating shaft 22 and the driving shaft 17, and transmit the power transmitted by the driving shaft 17 to the rotating shaft 22, thereby driving the movement of the cleaning plate 21. The driving shaft 17 is arranged between the driving motor 18 and the fixing block 26 and is fixedly connected to the driving motor 18 and the fixing block 26. Therefore, its rotation speed and direction can be adjusted by controlling the driving motor 18 to meet different cleaning requirements.

[0084] In this embodiment, when the driving motor 18 drives the driving shaft 17 to rotate, the driving shaft 17 drives the rotating shaft 22 to rotate with the help of the fixing block 26. The rotating shaft 22 realizes the rotation of the connecting member 25 relative to the sliding member 23 with the help of the connecting member 25 and the limiting member 24. Under the limiting action of the limiting member 24, when the rotating shaft 22 rotates to a certain angle, a longitudinal force is applied to the connecting member 25, causing the connecting member 25 to drive the sliding member 23 to slide up and down on the longitudinal guide rail 11. Further, when the rotating shaft 22 continues to rotate, a lateral force can be applied to the sliding member 23, and the longitudinal guide rail 11 slides laterally on the lateral guide rail 12 with the help of the sliding ring 16. Thus, with the contact surface between the cleaning plate 21 and the photovoltaic panel 1 on the longitudinal guide rail 11, the area of the photovoltaic panel 1 can be fully covered to achieve a comprehensive cleaning effect.

[0085] During the entire cleaning process, through the rotation of the rotating shaft 22, the longitudinal and lateral forces are gradually transmitted to the slider 23, enabling it to move in two directions, thereby driving the cleaning plate 21 to fully cover the surface of the photovoltaic panel for cleaning. This process is driven and controlled by the drive assembly, eliminating the need for manual operation and achieving automated cleaning, thus increasing the cleaning efficiency.

[0086] In some embodiments, the drive shaft 17 can also achieve an adjustable speed function by integrating devices such as frequency converters or speed governors. The drive motor 18 can automatically adjust the rotation speed of the drive shaft 17 according to the cleaning requirements, thereby controlling the moving speed of the cleaning plate 21 to ensure a better cleaning effect.

[0087] It should be noted that the drive motor 18 can be connected to the connection housing 14 by means of existing devices or connection methods to ensure its own stability, and further ensure that the drive motor 18 can normally drive the drive shaft 17. At the same time, a solar panel can be electrically connected to the drive motor 18 to supply additional power to itself. The drive motor 18 is also electrically connected to the photovoltaic panel 1. The above solutions are all existing means and can be thought of by those skilled in the art for better use of the present utility model. Therefore, they will not be described in detail herein. The present utility model includes, but is not limited to, devices and structures with the same effects as described above.

[0088] Furthermore, in a possible implementation manner, an elastic member sleeved outside the rotating shaft 22 is provided between the connecting member 25 and the fixed block 26. Since the entire cleaning process is based on the rotation of the rotating shaft 22, through this elastic member, the vibration and impact generated during the cleaning process can be effectively absorbed, reducing the stress and wear on the rotating shaft 22, the fixed block 26, and the connecting member 25, thereby extending the service life of the device. At the same time, both ends of the elastic member are respectively connected to the connecting member 25 and the fixed block 26, which can prevent the stability of the fixed block 26 during the rotation of the rotating shaft 22 and prevent it from disengaging from the rotating shaft 22, further ensuring the stable positions of the drive motor 18 and the drive shaft 17 and guaranteeing the normal progress of the entire cleaning process.

[0089] As an example, the elastic member can be a spring 27, which is made of highly durable materials such as stainless steel or high-strength alloy steel and has stable performance. In addition, the elastic member can also be a multi-layer spring 27 structure, with each layer having a different elastic coefficient to provide a wider buffering range and higher shock absorption capacity to adapt to different vibration and impact conditions.

[0090] The photovoltaic panel cleaning device provided by the embodiments of the present application can adjust the cleaning speed and achieve efficient cleaning by setting a drive assembly including multiple components such as the drive shaft 17, the fixed block 26, and the drive motor 18. At the same time, it provides additional support and stability to ensure that the cleaning assembly remains stable during the cleaning process and reduces the risk of accidental damage.

[0091] In this specification, the embodiments or implementation manners are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0092] It should be noted that the embodiments referred to as "an embodiment", "embodiment", "exemplary embodiment", "some embodiments", etc. in the specification may include specific features, structures or characteristics, but not every embodiment necessarily includes such specific features, structures or characteristics. In addition, such phrases do not necessarily refer to the same embodiment. Moreover, when combining specific features, structures or characteristics with an embodiment, it is within the knowledge scope of those skilled in the art to implement such features, structures or characteristics in combination with other embodiments, whether explicitly or implicitly described.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
