Detailed Implementation

[0039] This utility model discloses a photovoltaic system that can support a cleaning robot and prevent damage to the photovoltaic modules. This utility model also discloses a cleaning robot.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0042] Currently, the main products for photovoltaic power plants are photovoltaic modules with aluminum frames, which are used to fix the modules during installation. Because frameless photovoltaic modules are cheaper and have the advantage of avoiding the accumulation of mud, water, and dust at the frame, they are easier to clean and have gained a foothold in the photovoltaic industry.

[0043] Because frameless photovoltaic modules have no fixed support around them, the edges of the modules are relatively fragile due to the lack of frame protection, and cleaning robots can easily damage the photovoltaic modules when walking on them.

[0044] To address the aforementioned issues, this application provides a photovoltaic system in which a guide rail is installed at a preset position away from the frameless photovoltaic module for a cleaning robot to walk on. This prevents the cleaning robot from walking directly on the photovoltaic module, thus ensuring the safety of the photovoltaic module and helping to prevent damage to it.

[0045] like Figure 1 and Figure 2 As shown, the photovoltaic system of this application embodiment includes: photovoltaic module 101, module support 102 and guide rail 201.

[0046] Among them, photovoltaic module 101 includes, but is not limited to, frameless photovoltaic module. It should be noted that the method of this application can also be used for framed photovoltaic modules.

[0047] The guide rail 201 is used for the cleaning robot to move; therefore, the shape and size of the guide rail 201 need to be adapted to the walking wheels of the cleaning robot. The shape, size, and material of the guide rail 201 can be selected according to different needs and are not limited here. The guide rail 201 is arranged on at least one side of the photovoltaic module 101, and the guide rail 201 is at a preset distance from the photovoltaic module 101. It can be understood that the guide rail 201 is not installed on the photovoltaic module 101; the photovoltaic module 101 and the guide rail 201 only have a relative positional relationship.

[0048] Along the thickness direction of the photovoltaic module 101, the guide rail 201 is higher than the photovoltaic module 101 to prevent the cleaning robot from scratching the photovoltaic module 101 during its movement. The height difference between the guide rail 201 and the photovoltaic module 101 along the thickness direction can be set according to different needs.

[0049] The photovoltaic system disclosed in this application has a guide rail 201 arranged on at least one side of the photovoltaic module 101, and the guide rail 201 is at a predetermined distance from the photovoltaic module 101, i.e., there is a gap between the guide rail 201 and the photovoltaic module 101. The cleaning robot walks along the guide rail 201, thereby cleaning the photovoltaic module 101 without the photovoltaic module supporting the cleaning robot, thus avoiding damage to the photovoltaic module. In addition, the gap between the guide rail 201 and the photovoltaic module 101 prevents the cleaning robot from walking directly on the photovoltaic module 101, thus ensuring the safety of the photovoltaic module 101 and helping to prevent damage to the photovoltaic module 101.

[0050] In some embodiments, the guide rail 201 is fixed to the component support 102, and the connection method between the guide rail 201 and the component support 102 includes, but is not limited to, welding or threaded connection. Optionally, the guide rail 201 is mounted on the component support 102 via an adjusting block 202. The dimension of the adjusting block 202 along the thickness direction can be set according to the dimensions of the photovoltaic module 101 and the guide rail 201 along the thickness direction, and the dimension of the adjusting block 202 along the thickness direction is not specifically limited. The adjusting block 202 includes, but is not limited to, a rectangular block, with one side connected to the component support 102 and the other side connected to the guide rail 201. The connection method between the adjusting block 202 and the component support 102 includes, but is not limited to, welding or threaded connection, and the connection method between the adjusting block 202 and the guide rail 201 includes, but is not limited to, welding or threaded connection. It should be noted that, in this document, the guide rail 201 and the adjusting block 202 serve as a guide rail assembly 200, connecting the cleaning robot and the component support 102.

[0051] In some embodiments, a set of opposite sides of the photovoltaic module 101 are provided with guide rails 201. When multiple photovoltaic modules 101 are arranged along a first direction to form a photovoltaic string, the guide rails 201 can be arranged on both sides of the photovoltaic string perpendicular to the extension direction of the photovoltaic string, so that the cleaning robot can clean the photovoltaic string while walking along the guide rails 201, thereby improving the cleaning effect.

[0052] Depending on the size of the cleaning robot, the guide rail 201 can also be positioned outside the two sets of photovoltaic strings arranged along a second direction, which is perpendicular to the first direction. Optionally, the guide rail 201 can be arranged parallel to the side of the photovoltaic module 101.

[0053] Combination Figures 3 to 5 As shown, the cross-section of the guide rail 201 along the thickness direction is rectangular. Optionally, the guide rail 201 includes: a U-shaped body 2011 and a connecting section 2012, wherein the U-shaped body 2011 is configured for the cleaning robot to walk; the connecting section 2012 is connected to the U-shaped body 2011, and the connecting section 2012 is arranged opposite to or offset from the U-shaped body 2011, and the connecting section 2012 can be used to connect with the adjusting block 202.

[0054] in, Figure 3 As shown, the connecting segment 2012 is staggered with the U-shaped body 2011, which can be understood as the connecting segment 2012 and the U-shaped body 2011 not being directly opposite each other along the thickness direction. Optionally, the connecting segment 2012 consists of two segments, which are distributed at the opening of the U-shaped body 2011 and extend in a direction away from the opening of the U-shaped body 2011.

[0055] like Figure 4As shown, the connecting section 2012 and the U-shaped body 2011 are arranged opposite each other. This can be understood as the connecting section 2012 and the U-shaped body 2011 being arranged directly opposite each other along the thickness direction. The connecting section 2012 connects to the opening of the U-shaped body 2011, so that the cross section of the guide rail 201 along the thickness direction forms a closed rectangular structure.

[0056] like Figure 5 As shown, the side wall of the U-shaped body 2011 has a notch. By setting the notch, the weight of the guide rail 201 can be reduced. In addition, the notch is set along the extension direction of the guide rail 201, so that the notch can also guide the movement of the cleaning robot. The size, shape and position of the notch can be set according to different needs, and are not specifically limited here.

[0057] It should be noted that the guide rail 201 is a certain distance from the edge of the photovoltaic module 101, which ensures that the cleaning robot can walk stably on the guide rail 201 on both sides without contacting the frameless photovoltaic module 101. This helps to improve the stability of the cleaning robot's movement, avoid potential damage to the frameless photovoltaic module 101, and extend the service life of the photovoltaic module 101.

[0058] The above content describes the structure of the photovoltaic system. During the cleaning process of the photovoltaic system disclosed in the above embodiments, the structure of the cleaning robot can be further optimized. The following, in conjunction with... Figures 6 to 13 The structure of the cleaning robot is explained.

[0059] like Figures 6 to 9 As shown in the figure, this application embodiment also discloses a cleaning robot 300, including a crossbeam 301 and a walking wheel 304, wherein the walking wheel 304 is installed on the crossbeam 301, and the walking wheel 304 can cooperate with the guide rail 201 of the photovoltaic system and walk along the guide rail 201 of the photovoltaic system.

[0060] In some embodiments, the walking wheels 304 are arranged along the axial direction of the crossbeam 301, and the walking wheels 304 are provided at both ends of the crossbeam 301 in the axial direction, so that the cleaning robot 300 straddles the photovoltaic module 101 and cleans the photovoltaic module 101.

[0061] The cleaning robot 300 also has a roller brush 302 and an adjusting component 303 connected to its crossbeam 301. The roller brush 302 is used to clean the photovoltaic modules 101 of the photovoltaic system. Optionally, the roller brush 302 is located between the walking wheels 304 at both ends of the crossbeam 301. The length of the roller brush 302 along the axial direction of the crossbeam 301 can be set according to the size of the photovoltaic modules 101.

[0062] It should be noted that: An excessively long arrangement of photovoltaic modules 101 can cause the crossbeam 301 of the cleaning robot 300 to undergo elastic deformation under gravity. Furthermore, the lack of a frame for the photovoltaic modules 101 makes them relatively fragile. Without adequate measures to protect the intermediate wheels of the cleaning robot 300, the intermediate wheels could easily damage the photovoltaic modules 101 while they are moving on the frameless surface. Therefore, in this embodiment, the cleaning robot 300 eliminates the intermediate wheels, allowing the cleaning robot 300 to move along the guide rails 201 on both sides of the photovoltaic modules 101.

[0063] Furthermore, the concavity of the crossbeam 301 of the cleaning robot 300 under gravity can cause excessive compression of the photovoltaic module 101 at the deformed portion of the crossbeam 301, thereby increasing the current of the drive motor of the cleaning robot 300, reducing motor life, and consequently reducing the overall service life of the cleaning robot 300. Based on this, an adjustment component 303 is provided on the crossbeam 301 of the cleaning robot 300 to adjust the distance between the roller brush 302 and the photovoltaic module 101. The roller brush 302 moves radially relative to the crossbeam 301 to change the distance between the roller brush 302 and the photovoltaic module 101, thereby changing the cleaning force of the roller brush 302 on the photovoltaic module 101. In this paper, the radial direction of the crossbeam 301 is in the same direction as the thickness direction of the photovoltaic module 101.

[0064] In some embodiments, the brush bristles of the roller brush 302 can be uniformly attached to the photovoltaic module 101 by changing the radial position of the adjusting member 303 or changing the shape of the roller brush 302 (such as conical, saddle-shaped, etc.), thereby improving the cleaning effect of the cleaning robot 300 and extending the service life of the cleaning robot 300.

[0065] Optionally, there are at least two sets of roller brushes 302, arranged along the axial direction of the crossbeam 301. An adjusting member 303 is located between the roller brushes 302. For example, the adjusting member 303 is located at the midpoint of the axial direction of the crossbeam 301. All roller brushes 302 are connected to the adjusting member 303. The adjusting member 303 can adjust the radial distance of the roller brushes 302 relative to the crossbeam 301, thereby changing the radial distance between the roller brushes 302 and the photovoltaic module 101. This ensures that the bristles of the roller brushes 302 are evenly attached to the photovoltaic module 101, improving the cleaning effect and preventing excessive pressure from the roller brushes 302 on the photovoltaic module 101, which could affect the quality of the photovoltaic module 101.

[0066] Of course, there can be multiple sets of roller brushes 302, and the adjustment member 303 can be set according to the number of roller brushes 302. For example, at least two adjacent roller brushes 302 are provided with an adjustment member 303, that is, the adjustment member 303 is not limited to the middle position of the crossbeam 301.

[0067] Optionally, the connection method between the roller brush 302 and the adjusting member 303 includes, but is not limited to: a bearing seat 3021 is provided at one end of the axial direction of the roller brush 302, and a connecting seat 3022 is provided at the other end; the roller brush 302 is rotatably connected to the bearing seat 3021 and the connecting seat 3022 respectively; the bearing seat 3021 is connected to the adjusting member 303; and the connecting seat 3022 is connected to the rotation center of the traveling wheel 304.

[0068] Combination Figures 10 to 13 As shown, the adjusting member 303 in this embodiment includes: a first mounting plate 3031 and a second mounting plate 3032.

[0069] The first mounting plate 3031 is fixedly connected to the crossbeam 301. Optionally, the first mounting plate 3031 and the bearing seat 3021 of the roller brush 302 are connected by means including but not limited to welding or threaded connection. When the first mounting plate 3031 and the bearing seat 3021 are connected by threaded connection, the first mounting plate 3031 has an assembly hole 3034 to facilitate the engagement with the threaded part and realize the connection between the bearing seat 3021 and the first mounting plate 3031.

[0070] The second mounting plate 3032 extends radially along the crossbeam 301. Optionally, the first mounting plate 3031 is attached to the crossbeam 301, and the first mounting plate 3031 and the second mounting plate 3032 are arranged perpendicularly. The first mounting plate 3031 has mounting holes 3033, and the crossbeam 301 and the adjusting member 303 are connected through the mounting holes 3033. Specifically, the crossbeam 301 is mounted on the mounting holes 3033 through a connector. In some embodiments, there are two second mounting plates 3032, which are arranged symmetrically about the first mounting plate 3031, and the first mounting plate 3031 and the two second mounting plates 3032 form a U-shaped structure.

[0071] like Figure 10 As shown, multiple radially arranged holes can be provided on the crossbeam 301. The mounting holes 3033 can be connected at different heights to achieve the change of the radial height of the adjusting component 303, thereby changing the distance between the roller brush 302 and the crossbeam 301.

[0072] like Figure 11 As shown, in order to adjust the radial distance between the roller brush 302 and the crossbeam 301, a plurality of mounting holes 3033 are provided on the second mounting plate 3032 in this embodiment of the application. By selecting mounting holes 3033 at different radial heights, the distance between the adjusting member 303 and the crossbeam 301 can be changed, thereby changing the radial distance between the roller brush 302 and the crossbeam 301.

[0073] The number and spacing of the mounting holes 3033 can be set according to different needs, and all are within the protection range.

[0074] like Figure 12 As shown, the mounting hole 3033 can also be a waist-shaped hole extending radially. The adjusting member 303 is connected to the crossbeam 301 through the waist-shaped hole, which can change the radial height of the adjusting member 303, thereby changing the radial distance of the roller brush 302 relative to the crossbeam 301.

[0075] In this embodiment, the first mounting plate 3031 and the second mounting plate 3032 can be integrally formed into a U-shaped structure. In other optional embodiments, the adjusting member 303 may further include a third mounting plate 3035. The third mounting plate 3035 is connected to both the first mounting plate 3031 and the second mounting plate 3032. There are two third mounting plates 3035, which are arranged opposite to each other, so that the adjusting member 303 is formed into a box structure. Figure 13 As shown.

[0076] use Figure 13 The adjusting element 303 shown can be adopted Figure 10 The distance between the roller brush 302 and the crossbeam 301 is changed through the connection method shown. It should be noted that... Figure 13 The adjusting member 303 needs to be installed inside the crossbeam 301. The shape of the adjusting member 303 and its installation position relative to the crossbeam 301 can be configured according to different needs, and all are within the scope of protection.

[0077] It should be noted that the shape and size of the adjusting member 303 provided in this application embodiment can be set as needed. The adjusting member 303 includes, but is not limited to, a metal part.

[0078] In summary, this utility model provides a solution for cleaning frameless photovoltaic modules, improving the cleaning effect of the cleaning robot 300 and extending the service life of both the photovoltaic modules and the cleaning robot 300. It offers a more reliable and efficient solution for photovoltaic modules.
