Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, and in particular to a cleaning device for cleaning photovoltaic panels. Background Technology

[0002] With the increasing demand for renewable energy, photovoltaic (PV) power generation, as a clean and renewable energy source, has received widespread attention. PV panels are typically installed in side-by-side arrays, fixed to support poles to maximize the use of sunlight. However, in existing technologies, multiple PV panels are mounted on support poles, with the central section supported by the poles and the ends bent downwards due to their own weight, resulting in a flat, pole-like cross-section. Existing cleaning equipment often uses cylindrical brush heads; however, due to the curved shape of the PV panels, the cylindrical brush heads cannot effectively conform to the panels, creating significant blind spots during cleaning. This results in a large amount of dust remaining on the PV panel surface after cleaning, leading to low cleaning efficiency and negatively impacting photoelectric conversion efficiency. Utility Model Content

[0003] In view of the above problems, this application aims to provide a cleaning device that can completely cover and adapt to the curved shape of both ends of the photovoltaic panel, avoiding cleaning dead corners.

[0004] To achieve the above objectives, this application provides a cleaning device for cleaning photovoltaic panels, comprising: multiple photovoltaic panels arranged side-by-side, a machine body, a cleaning roller, and a first bristle cluster; the upper surface of the photovoltaic panel has an arc-shaped or stepped cross-section perpendicular to the array direction; the machine body is mounted on the photovoltaic panel, with one end of the machine body slidably connected to the upper edge of the photovoltaic panel and the other end of the machine body slidably connected to the lower edge of the photovoltaic panel; the machine body moves along the array direction of the photovoltaic panels; the cleaning roller is rotatably disposed below the machine body, and the machine body drives the cleaning roller to rotate around the rotation center of the cleaning roller; the first bristle cluster consists of multiple sets, and the multiple sets of the first bristle clusters are spirally arrayed on the surface of the cleaning roller; and the length of each set of the first bristle clusters is equal to the distance between the cleaning roller and the upper surface of the photovoltaic panel.

[0005] Unlike existing technologies, the first brush bristle cluster in the above solution maintains optimal contact with the photovoltaic panel surface at all times, ensuring stable cleaning performance. Simultaneously, the length design and helical array layout of the first brush bristle cluster prevent dust from re-adhering to the photovoltaic panel during cleaning, significantly improving cleaning efficiency and providing strong support for the efficient operation of photovoltaic power generation.

[0006] In some embodiments, the cleaning roller is a straight rod, and the cleaning roller is perpendicular to the array direction of the photovoltaic panel.

[0007] In some embodiments, the cleaning roller includes a roller core and a sleeve; the sleeve is fitted onto the roller core, and the length of the roller core is equal to the distance between the upper edge and the lower edge of the photovoltaic panel.

[0008] In some embodiments, the first bristle cluster includes: a plurality of bristles arranged in an array.

[0009] In some embodiments, multiple sets of the first bristle clusters constitute a first cleaning section; and further includes: a second bristle cluster; the second bristle clusters are multiple sets, and the multiple sets of the second bristle clusters are arranged in a ring around the rotation center of the cleaning roller on the surface of the cleaning roller; the multiple sets of the second bristle clusters constitute a second cleaning section, and there are two second cleaning sections, and the two second cleaning sections are respectively placed at both ends of the first cleaning section.

[0010] In some embodiments, the length of each group of second bristle clusters is equal to the distance between the cleaning roller and the upper surface of the photovoltaic panel.

[0011] Unlike existing technologies, this utility model provides a cleaning device for cleaning photovoltaic panels, which has the following beneficial effects:

[0012] This invention provides a cleaning device for cleaning photovoltaic panels, comprising: multiple photovoltaic panels arranged side-by-side, a machine body, a cleaning roller, and a first bristle cluster. The machine body moves along the photovoltaic panel array direction via a sliding connection, ensuring that the cleaning roller can fully cover the surface of each photovoltaic panel, effectively removing dust and debris. The rotation of the cleaning roller, combined with the length design and helical array layout of the first bristle cluster, allows the first bristle cluster to contact the photovoltaic panel surface with higher efficiency and coverage during cleaning. This not only enhances the cleaning force on the photovoltaic panel surface but also avoids secondary pollution caused by excessively long bristle clusters, ensuring a thoroughly clean photovoltaic panel surface after cleaning.

[0013] In addition, the cleaning roller is designed as a straight rod with a length equal to the height of the photovoltaic panel, ensuring good physical contact during the cleaning process and more uniform force transmission. This makes the cleaning roller stable throughout the cleaning process and avoids poor cleaning results caused by improper structure.

[0014] The second bristle clusters, arranged in a ring array, are positioned at both ends of the first cleaning section. This dual-cleaning configuration further enhances the comprehensiveness and effectiveness of the cleaning. The second bristle clusters supplement the cleaning process, especially in cleaning the edges of the photovoltaic panels and hard-to-reach corners, ensuring no areas are missed. Simultaneously, the length of the second bristle clusters is equal to the distance from the cleaning roller to the photovoltaic panel surface, further reducing the risk of dust re-adhesion. In summary, this technical solution, through optimized cleaning device design, improves the cleaning efficiency and effect of the photovoltaic panels, contributing to the efficient operation of the photovoltaic power generation system.

[0034] Please see Figures 1 to 5 This embodiment provides a cleaning device for cleaning photovoltaic panels, including: multiple photovoltaic panels 10 arranged side by side, a machine body 20, a cleaning roller 30, and a first bristle cluster 40. The upper surface of each photovoltaic panel 10 has an arc-shaped cross-section perpendicular to the array direction. It should be noted that during installation, the multiple photovoltaic panels 10 are arrayed and mounted on a support rod 60. The middle of each photovoltaic panel 10 is supported by the support rod 60, and both ends of the photovoltaic panel 10 bend downwards under their own weight, resulting in a flat cross-section. To accommodate this photovoltaic panel structure, the cleaning device achieves comprehensive coverage and efficient cleaning of the entire surface of the photovoltaic panel 10 through the sliding design of the machine body 20 and the rotation mechanism of the cleaning roller 30.

[0035] Specifically, the machine body 20 is mounted on the photovoltaic panel 10, with one end of the machine body 20 slidably connected to the upper edge of the photovoltaic panel 10 and the other end slidably connected to the lower edge of the photovoltaic panel 10. The machine body 20 moves along the array direction of the photovoltaic panels 10. This design ensures that the cleaning roller 30 can fully cover the surface of each photovoltaic panel 10. The cleaning roller 30 is rotatably disposed below the machine body 20, and the machine body 20 is used to drive the cleaning roller 30 to rotate around the rotation center of the cleaning roller 30. The first bristle cluster 40 consists of multiple sets, and the multiple sets of the first bristle cluster 40 are spirally arrayed on the surface of the cleaning roller 30. The length of each set of the first bristle cluster 40 is equal to the distance between the cleaning roller 30 and the upper surface of the photovoltaic panel 10. First, it should be noted that the spiral array refers to multiple sets of the first bristle clusters 40 spirally rising around the outer surface of the cleaning roller 30; the annular array refers to the objects after the array being connected end to end, as can be seen in the second bristle clusters 50 mentioned below.

[0036] When the cleaning device is started, the machine body 20, driven by the power source, rotates the cleaning roller 30 around its rotation center, causing the first bristle clusters 40 arranged in a spiral array on the cleaning roller 30 to clean the surface of the photovoltaic panel 10. The first bristle clusters 40 in the spiral array form a continuous spiral path on the surface of the cleaning roller 30, and there is a certain overlap area between each group of bristle clusters in the spiral path. This overlap ensures that no part is missed during the cleaning process, so that each group of bristle clusters can cover different areas of the photovoltaic panel 10 when the cleaning roller 30 rotates, achieving comprehensive contact and cleaning of the entire surface. In addition, when the cleaning roller 30 rotates, the first bristle clusters 40 move along the spiral path, generating a forward pushing force, which helps to transport the dust and impurities attached to the surface of the photovoltaic panel 10 forward, avoiding the problem of dust re-adhesion, thereby greatly improving the cleaning effect. Compared with simple horizontal or vertical arrangements, the spiral array design can significantly improve the uniformity and comprehensiveness of cleaning.

[0037] It should be noted that when the length of the first bristle cluster 40 is too long (i.e., the length of the first bristle cluster 40 is greater than the distance between the cleaning roller 30 and the upper surface of the photovoltaic panel 10), the first bristle cluster 40 brushes the surface of the photovoltaic panel 10 through its sidewalls, which makes it easy for dust adhering to the sidewalls to re-adhere to the photovoltaic panel 10 during the cleaning process, thus failing to achieve the cleaning effect. In this application, the length of each set of first bristle clusters 40 is equal to the distance between the cleaning roller 30 and the upper surface of the photovoltaic panel 10. At this time, the dust is bounced away in the direction of movement of the machine body 20 by the end of the first bristle cluster 40 (and the dust can also be sucked away by the suction device on the machine body 20), which can prevent the dust from re-adhering to the cleaned area, thereby improving the cleaning efficiency.

[0038] Through the above-described scheme, the end of the first bristle cluster 40 can always maintain optimal contact with the surface of the photovoltaic panel 10, ensuring the stability of the cleaning effect. At the same time, the length design and spiral array layout of the first bristle cluster 40 also avoid the problem of dust re-adhering to the photovoltaic panel 10 during the cleaning process, greatly improving the cleaning efficiency and providing a strong guarantee for the efficient operation of photovoltaic power generation.

[0039] Please see Figures 3 to 4 In some embodiments, the cleaning roller 30 is a straight rod, and the cleaning roller 30 is perpendicular to the array direction of the photovoltaic panel 10.

[0040] In this embodiment, the cleaning roller 30 adopts a straight rod design and is perpendicular to the array direction of the photovoltaic panel 10. This allows the cleaning roller 30 to fully utilize its contact area with the photovoltaic panel 10 during cleaning, thereby achieving a more effective cleaning result. Specifically, because the straight shape of the cleaning roller 30 is perpendicular to the arrangement structure of the photovoltaic panel 10, the cleaning roller 30 can evenly act on the surface of the photovoltaic panel 10 when rotating, ensuring that the brush bristles can fully contact and remove attached dust and debris during the cleaning process. At the same time, this design simplifies the manufacturing and installation process of the cleaning roller 30, reduces production costs, and facilitates subsequent maintenance and replacement.

[0041] In some embodiments, the cleaning roller 30 includes a roller core and a sleeve; the sleeve is fitted onto the roller core, and the length of the roller core is equal to the distance between the upper edge of the photovoltaic panel 10 and the lower edge of the photovoltaic panel 10.

[0042] In this embodiment, the cleaning roller 30 is designed with a combination structure of a roller core and a sleeve. Specifically, the roller core is a straight rod whose length is equal to the distance between the upper and lower edges of the photovoltaic panel 10. Regardless of which photovoltaic panel 10 is being cleaned, the length of the cleaning roller 30 can completely cover its surface. At the same time, the sleeve fitted on the outer surface of the roller core increases the strength and rigidity of the cleaning roller 30, ensuring that it will not deform or be damaged during the cleaning process.

[0043] Furthermore, the material and surface treatment of the sleeve can be optimized according to actual needs. For example, wear-resistant materials can be used, or a special coating can be applied to the surface to enhance the adhesion and service life of the cleaning elements, thereby further improving cleaning efficiency.

[0044] Please see Figure 4 In some embodiments, the first bristle cluster 40 includes: a plurality of bristles arranged in an array.

[0045] In this embodiment, each bristle is evenly distributed to form a dense first bristle cluster 40, enhancing the cleaning effect. This array arrangement allows the bristles to make more comprehensive contact with the photovoltaic panel 10 surface during cleaning, effectively removing attached dust and debris. The array design not only improves the cleaning ability of the bristles but also ensures a uniform distribution of force during cleaning, avoiding localized wear or damage and extending the service life of the cleaning device.

[0046] In addition, the material and rigidity of the bristles can be optimized as needed to adapt to different cleaning requirements and ensure the durability and stability of the cleaning effect.

[0047] Please see Figures 3 to 4 In some embodiments, multiple sets of the first bristle clusters 40 constitute the first cleaning section 41;

[0048] The cleaning device for cleaning photovoltaic panels also includes: a second bristle cluster 50; the second bristle cluster 50 is in multiple groups, and the multiple groups of the second bristle clusters are arranged in a ring around the rotation center of the cleaning roller 30 on the surface of the cleaning roller 30; the multiple groups of the second bristle clusters 50 form a second cleaning part 51, and there are two second cleaning parts 51, and the two second cleaning parts 51 are respectively placed at both ends of the first cleaning part 41.

[0049] In this embodiment, the multiple first bristle clusters 40 of the first cleaning section 41 are closely arranged, which can effectively remove dust and debris from the surface of the photovoltaic panel 10. The second bristle clusters 50 are arranged in a ring around the rotation center of the cleaning roller 30, and are designed as two opposing cleaning sections, located at both ends of the first cleaning section 41. This not only increases the cleaning area of ​​the cleaning roller 30, but also ensures that the edges and corners of the photovoltaic panel 10 can be covered during the cleaning process, avoiding any omissions.

[0050] Furthermore, the coordinated operation of the first cleaning unit 41 and the second cleaning unit 51 enables a dynamic cleaning mechanism to be formed during the cleaning process, reducing the re-adhesion of dust and dirt during the cleaning process, further improving cleaning efficiency, and enhancing the cleanliness and power generation efficiency of the photovoltaic panel 10.

[0051] In some embodiments, the length of each group of second bristle clusters 50 is equal to the distance between the cleaning roller 30 and the upper surface of the photovoltaic panel 10.

[0052] In this embodiment, the length of each set of second bristle clusters 50 is equal to the distance from the cleaning roller 30 to the upper surface of the photovoltaic panel 10, ensuring that the ends of the second bristle clusters 50 always maintain optimal contact with the surface of the photovoltaic panel 10, maximizing the cleaning effect. Similar to the length design of the first bristle clusters 40, this precise matching avoids the problem of dust re-adhesion caused by excessively long second bristle clusters 50, while also ensuring that the second bristle clusters 50 always fully contact the surface of the photovoltaic panel 10, improving the stability of the cleaning effect.

[0053] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0054] This invention provides a cleaning device for cleaning photovoltaic panels, comprising: multiple photovoltaic panels 10 arranged side-by-side, a machine body 20, a cleaning roller 30, and a first bristle cluster 40. The machine body 20 moves along the array direction of the photovoltaic panels 10 via a sliding connection, ensuring that the cleaning roller 30 can fully cover the surface of each photovoltaic panel 10, effectively removing dust and debris. The rotation of the cleaning roller 30, combined with the length design and spiral array layout of the first bristle cluster 40, allows the first bristle cluster 40 to contact the surface of the photovoltaic panels 10 with higher efficiency and coverage during cleaning. This not only enhances the cleaning force on the surface of the photovoltaic panels 10 but also avoids secondary pollution caused by excessively long bristle clusters, ensuring a thoroughly clean surface of the photovoltaic panels 10 after cleaning.

[0055] In addition, the cleaning roller 30 is designed as a straight rod with a length equal to the height of the photovoltaic panel 10, which ensures that the cleaning roller 30 can maintain good physical contact during the cleaning process and the force is transmitted more evenly. This makes the cleaning roller 30 maintain stability throughout the cleaning process and avoids poor cleaning effect due to improper structure.

[0056] The second bristle clusters 50, arranged in a ring array, are positioned at both ends of the first cleaning section 41. This dual-cleaning configuration further enhances the comprehensiveness and effectiveness of cleaning. The second bristle clusters 50 supplement the cleaning process, especially in cleaning the edges and hard-to-reach corners of the photovoltaic panel 10, ensuring no areas are missed. Simultaneously, the length of the second bristle clusters 50 is equal to the distance from the cleaning roller 30 to the surface of the photovoltaic panel 10, further reducing the risk of dust re-adhesion. In summary, this technical solution, through optimized cleaning device design, improves the cleaning efficiency and effect of the photovoltaic panel 10, contributing to the efficient operation of the photovoltaic power generation system.
