[0051] This utility model discloses a fixture for a photovoltaic system, which improves versatility and reduces production costs.

[0052] This utility model also discloses a photovoltaic system having the above-mentioned clamp.

[0053] 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.

[0054] 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.

[0055] A photovoltaic (PV) system consists of multiple installed PV modules with gaps between adjacent modules. When using a cleaning robot to clean the PV system, the system needs to form a connected track for the robot to move along. Currently, adjacent PV modules are connected by bridges, allowing multiple modules to be arranged sequentially in this direction as PV strings. The cleaning robot can then move along these bridges to clean the PV strings.

[0056] Currently, the cable trays and photovoltaic modules are connected by clamps, which have complex structures and poor versatility, resulting in high manufacturing costs.

[0057] Based on this, this application discloses a photovoltaic system and a clamp, wherein the clamp is used to connect photovoltaic modules and bridges, and the clamp can adapt to photovoltaic modules with different frame sizes, thereby improving versatility.

[0058] like Figures 1 to 3 As shown, the photovoltaic system includes: photovoltaic module 100, bridge 200 and fixture 300.

[0059] The photovoltaic modules 100 are arranged sequentially along a first direction, and adjacent photovoltaic modules 100 are connected by a bridge 200, so that the photovoltaic modules 100 form a track in the first direction that allows the cleaning robot 400 to move. The bridge 200 is connected to the frame of the photovoltaic modules 100 by a clamp 300.

[0060] In some embodiments, the photovoltaic module 100 includes a photovoltaic panel and a frame. A clamp 300 is connected to the frame, thereby connecting the photovoltaic module 100 to the clamp 300. Optionally, the frame includes a first side 101 and a second side 102, wherein the first side 101 and the second side 102 intersect and connect to form the apex corner of the frame; the first side 101 extends along a first direction, and the second side 102 extends along a second direction. The clamp 300 is partially connected to the first side 101 and partially to the second side 102.

[0061] It should be noted that this article only describes the arrangement of photovoltaic modules 100 along the first direction. For the arrangement of photovoltaic modules 100 in other directions, please refer to the description in this article.

[0062] Adjacent photovoltaic modules 100 are connected by a bridge 200, and the clamps 300 at both ends of the bridge 200 have the same structure, so as to reduce the types of clamps 300 and reduce production costs.

[0063] In this article, the first direction is the arrangement direction of the photovoltaic module 100, the bridge 200 and the fixture 300; the cleaning robot 400 walks on the upper surface of the photovoltaic module 100 in the third direction, which can be understood as the height direction of the photovoltaic module 100; the second direction, the first direction and the third direction are perpendicular to each other.

[0064] Combination Figures 2 to 9 As shown, the clamp 300 includes a first clamping part 301 and a second clamping part 302.

[0065] The first clamping part 301 and the second clamping part 302 are arranged along a third direction, with the first clamping part 301 located above the third direction and the second clamping part 302 located below the third direction. The first clamping part 301 and the second clamping part 302 are detachably connected, and after the first clamping part 301 and the second clamping part 302 are connected, the first end along the first direction is connected to the bridge frame 200, and the second end along the first direction is connected to the frame of the photovoltaic module 100.

[0066] Optionally, the second end of the clamp 300 is L-shaped to achieve the top corner connection between the clamp 300 and the frame of the photovoltaic module 100. This helps to increase the connection area between the clamp 300 and the photovoltaic module 100, improve the stability of the connection between the clamp 300 and the frame, and thus improve the stability of the connection between the clamp 300 and the photovoltaic module 100.

[0067] In this embodiment of the application, the distance between the first clamping part 301 and the second clamping part 302 along at least one of the first direction, the second direction and the third direction is adjustable, and the first direction, the second direction and the third direction are mutually perpendicular directions.

[0068] Different photovoltaic modules 100 can be clamped by changing the distance between the first clamping part 301 and the second clamping part 302 along the first direction, and these photovoltaic modules 100 have different dimensions along the first direction; different photovoltaic modules 100 can be clamped by changing the distance between the first clamping part 301 and the second clamping part 302 along the second direction, and these photovoltaic modules 100 have different dimensions along the second direction; different photovoltaic modules 100 can be clamped by changing the distance between the first clamping part 301 and the second clamping part 302 along a third direction, and these photovoltaic modules 100 have different dimensions along the third direction.

[0069] It can be understood that by changing the distance between the first clamping part 301 and the second clamping part 302 along at least one of the first direction, the second direction and the third direction, it is possible to adapt to photovoltaic modules 100 with different dimensions in that direction, that is, to adapt to photovoltaic modules 100 of different specifications, thereby improving the versatility of the clamp 300, reducing the number of clamps 300, and helping to reduce the processing cost of the clamp 300.

[0070] The first clamping part 301 includes: a first plate 3011, a first side plate 3012, a second side plate 3013, and a third side plate 3014.

[0071] Among them, the first end of the first plate 3011 along the first direction is close to the bridge 200, and the second end of the first plate 3011 along the first direction is close to the frame of the photovoltaic module 100.

[0072] The first side plate 3012 and the second side plate 3013 are distributed on both sides of the first plate 3011 along the second direction. The distance between the first side plate 3012 and the second side plate 3013 along the second direction can be set according to different needs. When the cable tray 200 needs to be clamped between the first side plate 3012 and the second side plate 3013, the distance between the first side plate 3012 and the second side plate 3013 is not less than the dimension of the cable tray 200 along the second direction; when the cable tray 200 is connected to the outer surface of the clamp 300, the distance between the first side plate 3012 and the second side plate 3013 along the second direction is not limited.

[0073] The dimension of the first side plate 3012 along the first direction is greater than the dimension of the second side plate 3013 along the second direction. The second side plate 3013 is located at the first end of the first plate 3011. The third side plate 3014 is located at the second end of the first plate 3011. The third side plate 3014 extends along the second direction, and along the second direction, the second side plate 3013 is located between the first side plate 3012 and the third side plate 3014.

[0074] Optionally, the first side plate 3012, the second side plate 3013 and the third side plate 3014 are all perpendicular to the first plate 3011, and the first plate 3011, the first side plate 3012, the second side plate 3013 and the third side plate 3014 are, but are not limited to, connected by an integral molding method.

[0075] The first end of the first side plate 3012 along the first direction is used to connect with the cable tray 200. The second end of the first side plate 3012 along the first direction and the third side plate 3014 are arranged in an L-shape. The first side plate 3012 is used to connect with the first side 101 of the frame of the photovoltaic module 100, and the third side plate 3014 is used to connect with the second side 102 of the frame of the photovoltaic module 100, so that the first clamping part 301 can limit the frame of the photovoltaic module 100 by using the first side plate 3012 and the third side plate 3014.

[0076] The second clamping part 302 includes: a second plate 3021, a fourth side plate 3022, a fifth side plate 3023, and a sixth side plate 3024.

[0077] The second plate 3021 is arranged opposite to the first plate 3011 along a third direction, and the second plate 3021 of the clamp 300 is higher than the first plate 3011 along the third direction. The first end of the second plate 3021 along the first direction is close to the cable tray 200, and the second end of the second plate 3021 along the first direction is close to the photovoltaic module 100.

[0078] The fourth side plate 3022 and the fifth side plate 3023 are distributed on both sides of the second plate 3021 along the second direction, and the distance between the fourth side plate 3022 and the fifth side plate 3023 along the second direction is greater than the distance between the first side plate 3012 and the second side plate 3013 along the second direction. Of course, the distance between the fourth side plate 3022 and the fifth side plate 3023 along the second direction can also be less than the distance between the first side plate 3012 and the second side plate 3013 along the second direction.

[0079] By utilizing the arrangement of the fourth side plate 3022 and the fifth side plate 3023, as well as the first side plate 3012 and the second side plate 3013, the strength of the clamp 300 along the second direction can be increased.

[0080] The fourth side plate 3022 is larger in dimension along the first direction than the fifth side plate 3023 is larger in dimension along the second direction. The fifth side plate 3023 is located at the first end of the second plate 3021. The sixth side plate 3024 is located at the second end of the second plate 3021 and is arranged along the second direction. Along the second direction, there is a first gap between the sixth side plate 3024 and the fourth side plate 3022. Along the first direction, there is a second gap between the sixth side plate 3024 and the fifth side plate 3023.

[0081] Optionally, the fourth side plate 3022, the fifth side plate 3023, and the sixth side plate 3024 are all perpendicular to the second plate 3021. The second plate 3021, the fourth side plate 3022, the fifth side plate 3023, and the sixth side plate 3024 may, but are not limited to, be integrally formed. It should be noted that the first clamping part 301 and the second clamping part 302 can be processed using a die-stamping process, which simplifies the processing method and significantly reduces processing costs. In this paper, the first clamping part 301 and the second clamping part 302 are, but are not limited to, galvanized magnesium-aluminum plates. Using the same material for the first clamping part 301 and the second clamping part 302 reduces the types of materials used and lowers costs. Furthermore, galvanized magnesium-aluminum plates have corrosion resistance and high strength, thus meeting the corrosion resistance and strength requirements of the clamp 300.

[0082] The first end of the fourth side plate 3022 along the first direction is used to connect with the cable tray 200, the second end of the fourth side plate 3022 along the first direction is used to fit with the first side 101 of the frame of the photovoltaic module 100, and the sixth side plate 3024 is used to fit with the second side 102 of the frame of the photovoltaic module 100, so that the second clamping part 302 can limit the frame of the photovoltaic module 100 by using the fourth side plate 3022 and the sixth side plate 3024.

[0083] Specifically, after the second clamping part 302 is assembled with the first clamping part 301, the first side plate 3012 and the second side plate 3013 are located between the fourth side plate 3022 and the fifth side plate 3023, and are connected to the cable tray 200 via the fourth side plate 3022 and the fifth side plate 3023, and the connection method includes, but is not limited to, connector connection. After the second clamping part 302 is assembled with the first clamping part 301, the sixth side plate 3024 and the third side plate 3014 are arranged along the first direction, and the distance between them is the dimension of the second side 102 of the frame of the photovoltaic module 100 along the first direction. It can be understood that the sixth side plate 3024 and the third side plate 3014 are clamped on both sides of the second side 102 along the first direction. Optionally, the sixth side plate 3024 is clamped on the side of the second side 102 away from the cable tray 200 along the first direction, and the third side plate 3014 is clamped on the side of the second side 102 close to the cable tray 200 along the first direction. After the second clamping part 302 is assembled with the first clamping part 301, the distance between the sixth side plate 3024 and the first side plate 3012 along the second direction is the dimension of the first side 101 of the frame of the photovoltaic module 100 along the second direction. It can be understood that the sixth side plate 3024 and the first side plate 3012 clamp the first side 101.

[0084] As can be seen from the above connection relationship, the clamp 300 of this application embodiment can realize the connection between the bridge 200 and the frame of the photovoltaic module 100 by using the first clamping part 301 and the second clamping part 302.

[0085] In some embodiments, both the first side plate 3012 and the second side plate 3013 are provided with a first waist-shaped hole 30121 extending in a third direction. The size and number of the first waist-shaped hole 30121 are not specifically limited.

[0086] Both the fourth side plate 3022 and the fifth side plate 3023 have a second oblong hole 30221 extending along the first direction. After the second clamping part 302 is assembled with the first clamping part 301, the second oblong hole 30221 and the first oblong hole 30121 have overlapping portions for installing a connector. The connector in this document includes, but is not limited to, a threaded rod. The connection between the second clamping part 302 and the first clamping part 301 can be achieved by using a connector. It should be noted that the positions of the first oblong hole 30121 and the second oblong hole 30221 are interchangeable.

[0087] The connector can move along the first oblong hole 30121 to change the relative distance between the first clamping part 301 and the second clamping part 302 in a third direction, that is, to change the distance between the first plate 3011 and the second plate 3021, thereby accommodating the clamping of the frame of photovoltaic module 100 with different thicknesses. The connector can move along the second oblong hole 30221 to change the relative distance between the first clamping part 301 and the second clamping part 302 in a first direction, that is, to change the distance between the sixth side plate 3024 and the third side plate 3014 of the clamp 300 in the first direction, to accommodate the situation where the second side 102 of different photovoltaic modules 100 has different dimensions in the first direction, thereby improving the applicability of the clamp 300 of this application, increasing its versatility, and reducing manufacturing costs.

[0088] In some embodiments, the end of the sixth side plate 3024 near the fourth side plate 3022 is a bendable toothed structure in the first direction. By changing the number of bendable toothed structures, the distance between the sixth side plate 3024 and the fourth side plate 3022 can be changed to adapt to the situation where the first side 101 of different photovoltaic modules 100 has different dimensions in the second direction, thereby improving the applicability of the fixture 300 of this application, increasing its versatility, and reducing manufacturing costs.

[0089] It should be noted that the number and size of the bendable toothed structures are not specifically limited.

[0090] In some embodiments, the first plate 3011 has a first through hole 30111 extending along a third direction, and the fourth side plate 3022 has a second through hole 30222 extending along a second direction.

[0091] Combination Figures 10 to 12 As shown, Figure 10 As shown, when there is no height difference between adjacent photovoltaic modules 100 along the first direction and no horizontal displacement difference in the third direction, the bridge 200 can be connected to the first through hole 30111 of the clamp 300 through a connector.

[0092] like Figure 11 As shown, when adjacent photovoltaic modules 100 along the first direction have a height difference in the third direction and no horizontal displacement difference in the second direction, the bridge 200 can be connected to the second through hole 30222 of the clamp 300 through a connector.

[0093] like Figure 12 As shown, when adjacent photovoltaic modules 100 along the first direction have no height difference in the third direction but have a horizontal displacement difference in the second direction, the bridge 200 can be connected to the first through hole 30111 of the clamp 300 through a connector.

[0094] like Figures 13 to 17 As shown, the cable tray 200 disclosed in this application embodiment includes: a first cable tray plate 201 and a second cable tray plate 202.

[0095] The first cable tray plate 201 and the second cable tray plate 202 are arranged intersectingly, and for example, the first cable tray plate 201 and the second cable tray plate 202 are arranged perpendicularly. Both the first cable tray plate 201 and the second cable tray plate 202 are provided with a plurality of waist-shaped holes along the length direction, and the waist-shaped holes extend along the length direction of the cable tray 200.

[0096] It should be noted that the length of the cable tray 200 can be set according to different needs. By connecting at least two cable trays 200 along the length direction, the overall length of the connected cable tray 200 can be changed, thereby adapting to different spacings between adjacent photovoltaic modules 100. Specifically, adjacent cable trays 200 can be connected through different oblong holes, thus changing the overall length of the connected cable tray 200.

[0097] In some embodiments, the first cable tray plate 201 and the second cable tray plate 202 are integrally formed, or the first cable tray plate 201 and the second cable tray plate 202 are welded together. In some embodiments, the first cable tray plate 201 and the second cable tray plate 202 are connected at the middle position. This can be understood as the L-shaped cable tray 200 having cuts at both ends of the bend, forming the first cable tray plate 201 and the second cable tray plate 202 connected only at the middle position.

[0098] The cable tray 200 has cutouts extending in the first direction at both ends, which facilitates the bending of the first cable tray plate 201 and the second cable tray plate 202 according to different installation needs. This ensures that the cable tray 200 can adapt to situations where there is a height difference between adjacent photovoltaic modules 100 in the third direction or a horizontal displacement difference in the second direction when connecting adjacent photovoltaic modules 100, thereby improving the applicability of the cable tray 200 in this embodiment.

[0099] During the connection process between the cable tray 200 and the clamp 300, the first cable tray plate 201 is attached to the first plate 3011 of the clamp 300, and the second cable tray plate 202 is attached to the fourth side plate 3022 of the clamp 300.

[0100] The following is in conjunction with the appendix Figures 14 to 17 The bending conditions of the first cable tray plate 201 and the second cable tray plate 202, as well as the connection method after bending, are described.

[0101] Figure 14 As shown, the first cable tray 201 includes: a middle section 2011, a first section 2012, and a second section 2013.

[0102] The first segment 2012, the middle segment 2011, and the second segment 2013 are arranged sequentially, with the middle segment 2011 extending along a first direction. Both the first segment 2012 and the second segment 2013 are arranged at an angle relative to the middle segment 2011 along a third direction. Optionally, the end of the first segment 2012 furthest from the middle segment 2011 is higher along the third direction than the end of the first segment 2012 closest to the middle segment 2011; the end of the second segment 2013 furthest from the middle segment 2011 is lower along the third direction than the end of the second segment 2013 closest to the middle segment 2011.

[0103] The first cable tray 201 with the above structure can meet the connection requirements of adjacent photovoltaic modules 100 with a height difference in a third direction. A cut is made at the bending position of the L-shaped cable tray 200, and the cut position of the cable tray 200 is bent at a certain angle using pliers. This enhances the compatibility of the cable tray 200 when encountering photovoltaic modules 100 with a large height difference in a third direction, resulting in a higher fit between the cable tray 200 and the clamp 300.

[0104] For example, the spacing between adjacent photovoltaic modules 100 along the first direction is 100mm, the height difference along the third direction is 50mm, the length of the L-shaped cable tray 200 is 180mm, the cut position of the cable tray 200 is bent with pliers, and it is connected to the clamp 300 on the side using two connectors (e.g., bolts).

[0105] like Figure 15 As shown, in adjacent photovoltaic modules 100, the clamp 300 of the one with the higher height along a third direction is connected to the first segment 2012, and the clamp 300 of the other is connected to the second segment 2013. Optionally, the fourth side plate 3022 of the clamp 300 of the one with the higher height is attached to the first segment 2012 and connected by a connector; the fourth side plate 3022 of the clamp 300 of the other is attached to the second segment 2013 and connected by a connector.

[0106] like Figure 16 As shown, the second cable tray 202 includes: a middle part 2021, a first part 2022, and a second part 2023.

[0107] The first part 2022, the middle part 2021, and the second part 2023 are arranged sequentially along a first direction. The first part 2022 and / or the second part 2023 are arranged along a second inclination relative to the middle part 2021.

[0108] The second bridge plate 202 with the above structure can meet the connection requirements of adjacent photovoltaic modules 100 when there is a horizontal displacement difference in the second direction. For example... Figure 17As shown, in adjacent photovoltaic modules 100, the clamp 300 of one is connected to the first part 2022, and the clamp 300 of the other is connected to the second part 2023. Optionally, the first plate 3011 of the clamp 300 of one is attached to the first part 2022 and connected by a connector; the first plate 3011 of the clamp 300 of the other is attached to the second part 2023 and connected by a connector.

[0109] For example, the spacing between adjacent photovoltaic modules 100 along the first direction is 200mm, and the size difference along the second direction is 50mm. Two L-shaped cable trays 200 are spliced ​​together, and the length of the cable tray 200 is 180mm. The cut position of the cable tray 200 is bent with pliers, and it is connected to the clamp 300 at the upper position using two connectors (e.g., bolts).

[0110] As can be seen from the above description, when adjacent photovoltaic modules 100 are arranged with a height difference in a third direction, the bridge 200 is connected to the third-direction surface of the clamp 300, for example, connected to the first plate 3011; when adjacent photovoltaic modules 100 are arranged flush in a third direction, the bridge 200 is connected to the second-direction surface of the clamp 300, for example, connected to the fourth side plate 3022.

[0111] The above arrangement allows for easy adjustment of the shape of the cable tray 200, enabling it to adapt to photovoltaic modules 100 with different arrangements. This allows the photovoltaic modules 100 to be connected to the cable tray 200 via the clamp 300, forming a track for the cleaning robot 400 to travel on.
