[0002] Photovoltaic cleaning robots are components used to clean dust, dirt, and other impurities from the surface of photovoltaic modules. They are widely used in photovoltaic power plant projects. Photovoltaic cleaning robots require extended commutation brackets to be installed on the flanges of photovoltaic modules at extreme positions to support the commutation of the cleaning robot. However, the current flat-plate connectors have poor connection stability when fixing the commutation brackets, which can easily lead to failure and damage to the photovoltaic cleaning robot. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a commutation position structure and a photovoltaic power station to improve the installation stability of the commutation position structure of the photovoltaic cleaning robot on the photovoltaic module.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A commutation bit structure, comprising:

[0006] The commutation bracket includes at least one connecting part that can fit against the outer side of the flange of the photovoltaic module, and at least one fixing part disposed on the connecting part;

[0007] The connector includes a connecting section and a bending section, wherein the connecting section is connected to the fixing part, and the bending section is capable of abutting against the inner side of the flange of the photovoltaic module.

[0008] Preferably, in the above-mentioned commutation position structure, the commutation position bracket includes a first connecting part and a second connecting part, the first connecting part and the second connecting part being connected to two outer walls adjacent to the flange of the photovoltaic module in the width direction and the length direction of the photovoltaic module, respectively; the connector includes at least two, and the two connectors are respectively connected and cooperated with the first connecting part and the second connecting part.

[0010] Preferably, in the above-described reversing position structure, the first connecting portion includes a connecting wall, the first bent segment includes a protruding edge away from the first connecting segment, and the connecting wall and the protruding edge abut against the inner and outer sides of the photovoltaic module flange in the width direction of the photovoltaic module.

[0011] Preferably, in the above-mentioned reversing position structure, the first connecting part includes a locking wall, the first bending section includes a fixed side wall, and the fixed side wall and the locking wall clamp the inner and outer sides of the photovoltaic module flange in the thickness direction of the photovoltaic module.

[0012] Preferably, in the above-mentioned reversing position structure, the length of the second bending segment is greater than the length of the first bending segment, and the length of the second bending segment is greater than the spacing of the notches on the flange of the photovoltaic module.

[0013] Preferably, in the above-mentioned reversing position structure, the connector further includes a third connector, which is disposed between the first connector and the first connecting part, and clamps and fixes the first connector to the flange of the photovoltaic module from both the inner and outer sides.

[0014] Preferably, in the above-mentioned reversing position structure, the third connector includes a third connecting segment and a third bending segment; the third connecting segment is disposed between the fixing part and the first connecting segment, and the third bending segment is disposed between the locking wall and the first bending segment, and the third bending segment and the first bending segment abut against the inner and outer sides of the photovoltaic module flange in the thickness direction of the photovoltaic module.

At the same time, the side wall of the bending section and the extended end can generate contact with the photovoltaic module's flange in two directions. By generating contact in two directions while maintaining the connection, the stability of the connection between the commutation structure and the photovoltaic module's flange can be further improved, reducing the risk of operational failure of the photovoltaic cleaning robot.

[0040] The core of this application is to disclose a commutation position structure and a photovoltaic power station, so as to improve the installation stability of the commutation position structure of the photovoltaic cleaning robot on the photovoltaic module.

[0041] To enable those skilled in the art to better understand the present application, embodiments of the present application will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model described in the claims. Additionally, the complete content of the structures represented in the following embodiments is not limited to those necessary for the solution of the utility model described in the claims.

[0042] like Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a reversing position structure, which includes a reversing position bracket extending outward from the flange of a photovoltaic module to support a photovoltaic cleaning robot, enabling the photovoltaic cleaning robot to clean the entire area of ​​the photovoltaic module. It also includes a connector that is fixedly connected to the reversing position bracket to form a clamping structure, thereby fixing the reversing position bracket on the flange of the photovoltaic module.

[0043] Specifically, such as Figure 3 As shown, the commutation bracket 10 includes at least one connecting portion 110 that can conform to the outer side of the photovoltaic module flange 30 to engage with at least one side of the photovoltaic module flange 30 and abut against the outer wall surface of the photovoltaic module flange 30 on the side away from the photovoltaic module. In some embodiments, the connecting portion 110 is a groove structure that can abut against the photovoltaic module flange 30 from the top and bottom of the photovoltaic module flange 30 in the vertical direction, as well as from the outer side of the photovoltaic module flange 30 away from the photovoltaic module. The connecting portion 110 is also provided with a fixing portion 120 to provide assembly space. It should be noted that the fixing portion 120 can be an integral bent flange structure based on the connecting portion 110, or a flange structure that is independently fixed on the connecting portion 110. The connecting portion 110 is provided with at least one fixing portion 120 to provide assembly space for the connector 20.

[0044] The connector 20 includes a connecting section and a bending section, forming a bent flange structure based on the connecting section through the bending section. The connector 20 can cooperate with the photovoltaic module flange 30 on the inner side of the photovoltaic module flange 30, and through fixing with the connecting part 110, it can achieve all-round locking of the photovoltaic module flange 30, completing the assembly of the commutation position structure. It should be noted that, unlike the commonly used planar plate structure, the connector 20 provided in this embodiment can generate a larger contact area with the photovoltaic module flange 30 through the protruding structure of the bending section. After the connecting section is locked with the fixing part 120, the commutation position structure is more stably set on the photovoltaic module flange 30. Furthermore, for the connector 20 with the bending structure, when it is fixed on the photovoltaic module flange 30 with a narrow frame structure, it can abut against the inner concave bottom surface of the photovoltaic module flange 30 through the bending section, thereby achieving multi-directional locking. For a wider frame, it can achieve a large-area contact through the bending section to improve connection stability.

[0045] Furthermore, in order to improve the fixing effect of the commutation structure on the photovoltaic module flange 30, in some embodiments of this disclosure, such as... Figure 4 As shown, the commutation bracket 10 includes a first connecting portion 130 and a second connecting portion 150, which correspond to the fixing portion 120 to achieve connection on the photovoltaic module flange 30. It should be noted that the first connecting portion 130 and the second connecting portion 150 are connected to two adjacent outer walls of the photovoltaic module flange 30 in the width and length directions of the photovoltaic module, respectively, so that the first connecting portion 130 and the second connecting portion 150 cooperate to fix the commutation bracket 10 at one corner of the photovoltaic module flange 30. Correspondingly, at least two connectors 20 are provided, and they are connected and cooperate with the first connecting portion 130 and the second connecting portion 150, respectively. This structure not only allows the commutation structure to have a larger locking area on the photovoltaic module flange 30, but also forms two perpendicular connection points on the photovoltaic module flange 30, thereby achieving stable locking of the commutation structure at one corner of the frame.

[0046] Based on the above embodiments, such as Figure 5 , Figure 6 and Figure 7As shown, the connector 20 includes a first connector 210 and a second connector 220. The first connector 210 is used to cooperate with the first connecting part 130, and specifically includes a first connecting section 2110 and a first bending section 2120. The first connector 210 and the first connecting part 130 are clamped and fixed to the photovoltaic module flange 30 from the inner and outer sides. Typically, the first connecting part 130 abuts against the photovoltaic module flange 30 from the outer side of the photovoltaic module flange 30, that is, the side of the photovoltaic module flange 30 away from the inner photovoltaic module, while the first connector 210 passes through the first bending section. The first connector 2120 extends into the inner side of the photovoltaic module flange 30 and abuts against the side of the photovoltaic module flange 30 facing the photovoltaic module. The first connecting segment 2110 on the first connector 210 is locked to the first fixing part 140 corresponding to the first connecting part 130. That is, the first fixing part 140 has a locking hole 1410, and the first connecting segment 2110 has a corresponding connecting hole 21110, so that the position of the first connector 210 and the first connecting part 130 can be locked by bolts, thereby fixing the commutation bracket 10 on the photovoltaic module flange 30. The second connector 220 includes a second connecting segment 2210 and a second bending segment 2220, which are locked to the second connecting part 150 and the second fixing part 160 corresponding to the second connecting part 150. Its connection structure and method are the same as those of the first connector 210, and will not be described again here.

[0047] In some embodiments of this disclosure, the mating connection structure of the first connector 210 and the first connecting portion 130 is used as an example for illustration. The first connecting portion 130 includes a connecting wall 1310, which is the inner edge of the first connecting portion 130 along the photovoltaic module arrangement direction. It abuts against the edge of the photovoltaic module in its length or width direction. In this embodiment, it is the edge in the width direction of the photovoltaic module. The first bending segment 2120 includes a protruding edge 21210. The first bending segment 2120 is a bending structure based on the first connecting segment 2110, and the protruding edge 21210 is the edge structure of the first bending segment 2120 away from the first connecting segment 2110. Figure 8 , Figure 9 and Figure 10 As shown, in the thickness direction of the photovoltaic module, the first bent section 2120 can abut against the inner and outer sides of the photovoltaic module flange 30 with the first connecting portion 130, while in the width direction of the photovoltaic module, as... Figure 9 and Figure 10 As shown, the protruding edge 21210 of the first bent section 2120 can abut against the inner and outer sides of the photovoltaic module flange 30 with the connecting wall 1310, that is, the first connector 210 not only has a larger contact area with the photovoltaic module flange 30, but also... Figure 10As shown, it can simultaneously cooperate with the first connecting part 130 in the width and thickness of the photovoltaic module in two mutually perpendicular directions to achieve multi-directional fixation of the reversing position structure. It can achieve stable locking for narrower frame structures, such as 9mm or less.

[0048] In other embodiments of this disclosure, for the flange 30 of a photovoltaic module with a wide frame structure, such as Figure 11 As shown, the first connecting part 130 also includes a locking wall 1320, which is the wall surface of the first connecting part 130 in the thickness direction of the photovoltaic module. Correspondingly, the first bending section 2120 includes a fixed side wall 21220, which is the side of the first bending section 2120 facing the first connecting section 2110. The locking wall 1320 and the fixed side wall 21220 lock the inner and outer sides of the photovoltaic module flange 30 in the thickness direction of the photovoltaic module, which can also realize the stable setting of the reversing position structure on the photovoltaic module flange 30. In conjunction with the foregoing embodiments, the reversing position structure provided in this disclosure, in the mating area between the first connecting part 130 and the first connecting member 210, through the first bending segment 2120 provided on the first connecting member 210, can achieve locking in the thickness direction of the photovoltaic module flange 30 with a wide frame structure. Compared with the prior art, it has a larger contact area to ensure the connection strength requirement. For the photovoltaic module flange 30 with a narrow frame structure, it can achieve locking in two perpendicular directions from the thickness direction and the width direction of the photovoltaic module, resulting in a more stable connection effect. This allows the reversing position structure to adapt to photovoltaic module flange 30 structures of different sizes. In photovoltaic power station projects, photovoltaic module flanges 30 with different sizes can be installed through a single-size reversing position structure, thus meeting the reversing requirements of the photovoltaic cleaning robot, improving the universality of the reversing position structure, and reducing the production, storage, transportation, and assembly costs of parts.

[0049] In other embodiments of this disclosure, such as Figure 13 As shown, the second connecting part 150 is correspondingly provided with a second fixing part 160, which cooperates with the second connecting member 220 to realize the locking point setting of the commutation position structure in the length direction of the photovoltaic module. It should be noted that the assembly process of the second connecting member 220 is similar to that of the first connecting member 210, and will not be described again here. Further explanation is needed regarding... Figure 12 As shown, some current photovoltaic modules have a notch 310 at the corner for corner wiring. Based on this, such as... Figure 14As shown, the length of the second bending segment 2220 corresponding to the second connector 220 needs to be greater than the length of the first bending segment 2120 corresponding to the first connector 210, so that the second connector 220 has a larger span area. The length of the second bending segment 2220 is greater than the spacing of the notches 310 on the photovoltaic module flange 30. When part of the structure of the second connector 220 is located in the area where the notches 310 are set on the photovoltaic module flange 30, the longer span of the second bending segment 2220 still has sufficient contact area with the photovoltaic module flange 30 while the area of ​​the notches 310 is empty. While covering the area of ​​the notches 310, it can achieve a firm connection effect with the photovoltaic module flange 30.

[0050] Furthermore, in actual projects, photovoltaic module flanges 30 not only have differences in width and narrow frame structures, but also differences in height in the vertical direction, i.e., in the thickness direction of the photovoltaic module. To further improve the versatility of the commutation structure and reduce the workload of on-site surveys and customized production, such as... Figure 15 , Figure 16 and Figure 17 As shown, in some embodiments of this disclosure, the commutation position structure further includes a third connector 230. First, the commutation position bracket 10 in the commutation position structure is adapted to the photovoltaic module flange 30 structure with the maximum height for production and use. That is, for the photovoltaic module flange 30 with the maximum height dimension during use, the commutation position structure can fit and fasten with the photovoltaic module flange 30. With the cooperation of the first connector 210 and the first fixing part 140, and the cooperation of the second connector 220 and the second fixing part 160, the commutation position bracket 10 is fixed on the photovoltaic module flange 30, and the commutation position structure is fixed without the need for an additional connector 20.

[0051] Based on this, when the reversing bracket 10 of the same size structure is fixed on the photovoltaic module flange 30 with a smaller height, it is cooperated with the photovoltaic module flange 30 through the third connector 230. Specifically, taking the connection structure at the position of the first connector 210 as an example, the third connector 230 is also a bent structure, including a third connecting section 2310 and a third bent section 2320. At the same time, the third connector 230 is placed between the first connector 210 and the first fixing part 140 to cooperate with the first connector 210 and clamp and fix the inner and outer sides of the photovoltaic module flange 30 in the thickness direction of the photovoltaic module. Specifically, the third connecting segment 2310 of the third connector 230 is disposed between the first connecting segment 2110 and the first fixing part 140, and is fitted to the first fixing part 140, and is connected to the first fixing part 140 and the first connector 210 as an integral structure by bolts; while the third bending segment 2320 is disposed between the locking wall 1320 of the first connecting part 130 and the first bending segment 2120, specifically the third bending segment 2320 and the locking wall 1320 are disposed on the photovoltaic module flange 30. The third connecting member 230 is arranged on the same side and spaced apart, so that after the third connecting member 230 is connected to the first fixing part 140, the third bending section 2320 replaces the locking wall 1320 of the first connecting part 130, and cooperates with the first bending section 2120 to clamp one side of the photovoltaic module flange 30. At the same time, in the height direction of the photovoltaic module flange 30, the third bending section 2320 and the first bending section 2120 clamp the photovoltaic module flange 30 from the inner and outer sides of the photovoltaic module flange 30, thereby realizing the fixation of the reversing position structure.

[0052] It should be noted that in the above embodiments, the defect of the commutation position structure for the photovoltaic module flange 30 with a small height is that the span of the first connecting part 130 in the thickness direction of the photovoltaic module is greater than the height of the photovoltaic module flange 30, making it impossible to assemble the commutation position bracket 10. At this time, by setting a third connecting member 230 with a bending structure, the third connecting member 230 is fixed to the first fixing part 140, so that the third bending segment 2320 is located between the two walls of the first connecting part 130 in the thickness direction of the photovoltaic module. Correspondingly, the distance between the third bending segment 2320 and the top wall of the photovoltaic module flange 30 is reduced relative to the original distance between the top and bottom walls, so as to adapt to the photovoltaic module flange 30 with a small height and achieve stable clamping of the photovoltaic module flange 30.

[0053] In addition, considering that the thickness of the photovoltaic module flange 30 commonly used in current projects is 30mm, 35mm, etc., the commutation position structure usually needs to be adapted to the photovoltaic module flange 30 with the largest thickness. That is, the first connecting part 130 in the commutation position bracket 10 has a span distance of 35mm in the photovoltaic module thickness direction. On this basis, after the third connecting part 230 is fixed on the first fixing part 140, it maintains a 30mm gap with the bottom of the first connecting part 130 to meet the assembly requirements of the photovoltaic module flange 30 with a smaller thickness. Considering the errors that may occur during production and assembly, in some embodiments of this disclosure, the third connector 230 is provided with an adjustment hole 23110, and the fastening bolt passes through the adjustment hole 23110 and is locked to achieve the fixed setting of the third connector 230 on the first fixing part 140. It should also be noted that the adjustment hole 23110 is an elongated hole structure, and its length direction is the thickness direction of the photovoltaic module flange 30, so that the third connector 230 can cooperate with the fastening bolt within the length adjustment range of the adjustment hole 23110, thereby realizing the adjustment of the distance between the third bending section 2320 and one side wall of the photovoltaic module flange 30, and further improving the versatility of the reversing position structure.

[0054] Furthermore, to improve the connection stability of the reversing position structure, in the reversing position structure provided in this embodiment, the third connecting segment 2310 and the third bending segment 2320 of the third connector 230 are arranged perpendicularly, so that the third connector 230 has an L-shaped structure and good structural strength. It should also be noted that the first connector 210 and the second connector 220 with flanged structures can also adopt an L-shaped structure to meet the connection strength requirements.

[0055] Furthermore, this disclosure also provides a photovoltaic power station, which includes multiple photovoltaic modules and a photovoltaic cleaning robot capable of operating on the surface of the photovoltaic modules to clean the surface of the photovoltaic modules. It should also be noted that the frame of the photovoltaic module located at the reversing position of the photovoltaic cleaning robot is provided with the reversing position structure provided in any of the above embodiments. Since the reversing position structure has the technical effects provided in any of the above embodiments, the photovoltaic power station also has the above technical effects, which will not be repeated here.
