DETAILED DESCRIPTION

[0037] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are for example only, and those skilled in the art may think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0038] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0039] like Figures 1 to 8The figure shows a roller brush of a photovoltaic cleaning robot, which includes a rotating shaft body 1, a plurality of cleaning members arranged along the axial direction are arranged around the rotating shaft body 1, and a plurality of axial slots 4 are arranged around the rotating shaft body 1, and each cleaning member is detachably inserted into the axial slot 4. Figures 1 to 6 As shown, the axial slot 4 can be a straight slot, which is more convenient for disassembly and maintenance. However, other shapes can also be used, such as Figures 7 to 8 The spiral groove is shown. Although the disassembly and assembly is more troublesome than the linear groove, the spiral setting makes the axial length of the cleaning part longer, which is beneficial for cleaning. In addition, the spiral shape is also beneficial for pushing the dirt to one end for discharge.

[0040] In some embodiments, Figure 6 As shown, the number of axial slots 4 is six, and of course the number can be increased or decreased. By setting more axial slots 4, it is convenient to add or reduce cleaning parts according to needs, so as to be suitable for photovoltaic panel surfaces with different dirt, save the consumption of cleaning parts, and help reduce the cost of use. This is also an additional technical effect brought about by the provision of each cleaning part detachably inserted in the axial slot 4 in the present invention, and the premise for achieving this effect is to set more axial slots 4.

[0041] like Figure 1 , 2 As shown in Figures 3 and 4, the cleaning element includes a cleaning brush 2 and a scraping strip 3. The number of the cleaning brush 2 and the scraping strip 3 is one or more, and each cleaning brush 2 and the scraping strip 3 is distributed along the circumference of the rotating shaft body 1. In this example, three cleaning brushes 2 are provided, which are evenly distributed along the circumference of the rotating shaft body 1, and one scraping strip 3 is provided, which is provided between two adjacent cleaning brushes 2. In this way, since the contact area of ​​the scraping strip 3 is larger, the relative resistance is also larger. Although the power of the driving unit can be increased to increase the driving force, the surface force on the photovoltaic panel will also be enhanced. Then, after the design according to the above scheme, the entire load design is relatively uniform, and at the same time, the advantage of the combined cleaning element in cleaning the surface of the photovoltaic panel is also brought into play.

[0042] If the six axial slots 4 are all filled with cleaning members, that is, there are multiple cleaning brushes 2 and scraping strips 3, the cleaning brushes 2 and scraping strips 3 are alternately arranged along the circumference of the rotating shaft body 1. In this way, alternating combined cleaning is formed to maximize the cleaning efficiency.

[0043] In some embodiments, Figure 5 As shown, a groove 11 is provided between the second elastic base 8 of the scraper strip 3 and the elastic scraper plate 9 and / or the elastic scraper plate 9 itself, which is conducive to the swing of the elastic scraper plate 9. This design is conducive to optimizing the surface force of the scraper strip 3 on the photovoltaic panel, and is also conducive to smoother rotation of the roller brush.

[0044] The groove 11 can be arranged on one side of the scraper strip 3, or on the other side of the scraper strip 3, or on both sides at the same time. In this example, the groove 11 is arranged on both sides at the same time.

[0045] In some embodiments, Figure 1 , 2 , 3, and 4, it also includes an end cap 12 detachably connected to at least one end of the shaft body 1, and the end cap 12 is used to close the axial slot 4 so that each cleaning member is axially limited in the slot. As shown in the drawings, the end caps 12 are provided at both ends of the shaft body 1.

[0046] Further, in order to quickly disassemble and assemble the roller brush for easy use and maintenance, as Figure 1 , 2 As shown in FIG. 3 , the end cover 12 is provided with a connecting shaft 13, and the connecting shaft 13 is used for detachably connecting to the output end of the drive unit.

[0047] Furthermore, in order to further quickly disassemble and assemble the roller brush for easy use and maintenance, as Figure 2 As shown, the connecting shaft 13 is provided with a keyway 14. In particular, the keyway 14 is provided with an outer opening, so as to be conveniently and quickly inserted axially with the output end of the drive unit for transmission connection, so as to achieve the purpose of rapid disassembly and assembly.

[0048] The driving unit may be a motor, or may be a motor that is driven by a transmission structure to form an output end.

[0049] Furthermore, in order to quickly disassemble and assemble the end cover 12, a plurality of connection holes 16 are provided at the end of the shaft body 1, and the connection between the end cover 12 and the shaft body 1 is achieved by bolt connection.

[0050] In some embodiments, the cleaning member includes an elastic base and a cleaning portion disposed on the elastic base, and the elastic base is provided with a matching portion that is inserted and matched with the axial slot 4 in the axial direction, but is limited in the radial direction. In this way, the use of elastic deformation is conducive to the cleaning member having a higher adaptability during cleaning. In the present disclosure, since the cleaning member includes a cleaning brush sheet 2 and a scraper sheet 3, the specific structures are respectively illustrated below.

[0051] In some embodiments, Figure 4 As shown, the cleaning brush 2 includes a first elastic base 5 and bristles 6 arranged on the first elastic base 5. The first elastic base 5 is provided with a first matching portion 7 which is inserted and matched with the axial slot 4 in the axial direction, but is limited in the radial direction.

[0052] In order to further facilitate production and manufacturing, multiple cleaning brushes 2 are arranged along the axial direction, so that they can be inserted in sequence to adapt to the technical solution of the longer shaft body 1, thereby improving the cleaning efficiency during cleaning without increasing the difficulty of production and manufacturing.

[0053] In some embodiments, Figure 4 , 5 As shown, the scraper strip 3 includes a second elastic base 8 and an elastic scraper plate 9 arranged on the second elastic base 8. The second elastic base 8 is provided with a second matching portion 10 which is inserted and matched with the axial slot 4 in the axial direction, but is limited in the radial direction.

[0054] Furthermore, the second elastic base 8 and the elastic scraper 9 are integrally formed as a one-piece component, so that the scraper strip 3 can be integrally formed by an extrusion process, simplifying the manufacturing difficulty.

[0055] The first elastic base 5 and the scraper strip 3 can be made of elastic plastic, silica gel, rubber or other materials.

[0056] The cross-sectional shape of the axial slot 4 is roughly an arrow shape with an arc-shaped tip. Of course, other suitable shapes may also be used, such as a dovetail shape.

[0057] In some embodiments, Figure 2 , 3 As shown in FIG. 4 , the circumferential portion of the shaft body 1 between adjacent cleaning members is provided with an arc-shaped smooth surface 15, and the circumferential portion of the end cover 12 is level with or lower than the circumferential portion of the shaft body 1. This facilitates the outflow of dirt between adjacent cleaning members and improves cleaning efficiency.

[0058] In the present disclosure, the shaft body 1 can be designed with aluminum alloy to improve lightness, which is conducive to making the axial length of the shaft body 1 longer, thereby improving cleaning efficiency, while the end cover 12 is designed with stainless steel to improve transmission strength, reliability and durability. As mentioned above, the end cover 12 is bolted to the end of the shaft body 1 through the connection hole 16, forming a flange connection, which has a higher transmission strength, thereby facilitating reliability and durability.

[0059] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0060] The above description is only an illustrative embodiment of the present invention, so any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
