Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support system cleaning technology, and in particular to a cable tray mechanism. Background Technology

[0002] Currently, in many applications of photovoltaic (PV) support systems, a rotary drive device is installed on the main beam of the PV support to drive the main beam to rotate. Two axially adjacent PV modules on either side of the rotary drive device need to be separated by a distance to avoid the drive device. In this case, a cable tray needs to be added between these two PV modules to allow the cleaning robot to pass through. Simultaneously, a small power supply component is installed between the two separated PV modules to power the control box. This power supply component occupies the purlin fixing holes on both sides of the separation, making it impossible to install a conventional cable tray, thus making it difficult for the cleaning robot to cross this separation.

[0003] Therefore, it is necessary to provide a new cable tray mechanism to solve the above problems. Utility Model Content

[0029] Please see Figures 1 to 7 As shown, this embodiment discloses a bridge mechanism suitable for connecting two adjacent photovoltaic modules 10 in the same row, so that a cleaning robot can pass smoothly.

[0030] The photovoltaic module 10 includes a frame 101 and a photovoltaic panel 102. The frame 101 surrounds the outer periphery of the photovoltaic panel 102 and includes a top plate 1011, a side plate 1012, and a bottom plate 1013. The top plate 1011 and the bottom plate 1013 are positioned opposite each other on the same side of the frame 101. The two ends of the side plate 1012 are perpendicularly connected to the top plate 1011 and the bottom plate 1013, respectively. The bottom plate 1013 is fixedly connected to the purlins of the photovoltaic support structure. Each row of photovoltaic supports is equipped with at least one rotary drive device 20 to drive the main beam 30 to rotate, thereby rotating the photovoltaic module 10 to maximize the conversion of solar energy into electrical energy. The photovoltaic modules 10 are arranged along the length of the main beam 30. Two photovoltaic modules 10 on either side of the rotary drive device 20 are spaced apart to avoid obstructing the rotary drive device 20.

[0031] Please see Figure 1 As shown, in some embodiments, a power supply component 40 is provided between the two photovoltaic modules 10 for supplying power to the control box, and the power supply component 40 is fixedly installed on the purlin.

[0032] Please see Figures 1 to 3As shown, the cable tray mechanism in this embodiment includes two sets of cable tray assemblies, connecting the frame 101 of the photovoltaic module 10 for the cleaning robot to pass through. Each set of cable tray assemblies includes an overlap member 1 and two locking members 2. The two ends of the overlap member 1 overlap the corresponding sides of the frame 101 of the two photovoltaic modules 10, and the two locking members 2 connect the overlap member 1 to the two frame 101 respectively, so that the cable tray assembly is fixed by the frame 101.

[0033] Please see Figures 2 to 6 As shown, the connecting member 1 includes a first plate portion 11, a second plate portion 12, and a third plate portion 13 connecting the first plate portion 11 and the second plate portion 12. The first plate portion 11 and the second plate portion 12 are arranged parallel to each other, and the third plate portion 13 connects the first plate portion 11 and the second plate portion 12 on the same side. The cross-section of the connecting member 1 is C-shaped, and the first plate portion 11 at least partially fits the top plate portion 1011 of the frame 101. With this arrangement, the connecting members 1 of the two sets of bridge assemblies overlap the two side frames 101 through the first plate portion 11, forming a basic path for the cleaning robot to pass through.

[0034] Please see Figures 2 to 7 As shown, the locking member 2 includes a base 21 and a hook 22. The hook 22 is disposed on the base 21, and the base 21 is fixedly connected to one end of the overlapping member 1. The hook 22 is used to engage with the frame 101 of the photovoltaic module 10. Specifically, in this embodiment, the base 21 and the hook 22 are integrally disposed, and the hook 22 is fixedly connected from the base 21 to one end of the second plate 12. The hook 22 is used to engage with the bottom plate 1013, and at least one of the second plate 12 and the base 21 is at least partially attached to the bottom plate 1013. With this configuration, the frame 101 of the photovoltaic module 10 is clamped in the thickness direction, i.e., the upper and lower sides of the frame 101. In this embodiment, the second plate 12 is attached to the bottom plate 1013, i.e., the overlapping member 1 clamps the frame 101 from the top and bottom, restricting the vertical freedom of the bridge structure, and is fixed to the frame 101 by the locking member 2, so that the overall structure is reliable.

[0035] Please see Figure 4 , Figure 5 and Figure 7 As shown, the hook portion 22 includes a connecting portion 221 and a flat portion 222. The flat portion 222 is parallel to the base portion 21 and connected by the connecting portion 221. At least a portion of the bottom plate portion 1013 of the frame 101 abuts against the connecting portion 221. Specifically, the flat portion 222 is located parallel above the base portion 21, and the connecting portion 221 is bent to connect the flat portion 222 to the same side of the base portion 21. With this configuration, the locking fastener 2 can limit the cable tray assembly to the frame 101 through a simple bending structure, without the need to drill holes in the frame 101, thus avoiding damage to the photovoltaic module 10.

[0036] Furthermore, in this embodiment, the width of the flat plate portion 222 is not less than half the width of the base plate portion 1013. This configuration not only provides sufficiently stable positioning of the frame 101 but also accommodates various widths of the frame 101.

[0037] Please see Figures 4 to 7 As shown, the second plate portion 12 has a first through hole 121, and the base portion 21 has a second through hole 211. Fasteners 3 pass through the first through hole 121 and the second through hole 211 and are locked in place to fix the second plate portion 12 to the base portion 21. The fasteners 3 are bolt assemblies or other commonly used fasteners for fixing. With this arrangement, since the first plate portion 11 is located on the upper side and the second plate portion 12 is located on the lower side, the fasteners 3 are used on the lower side of the bridge assembly and the frame 101 to lock the overlapping member 1 and the locking member 2. This ensures that the bridge assembly can be stably installed on the frame 101. The fasteners 3 are located at the bottom of the bridge assembly and will not affect the normal operation of the cleaning robot. This avoids the possibility of the fasteners 3 being located on the upper surface or side of the frame 101, which could cause wear to the robot's wheels or guide wheels and hinder normal operation.

[0038] Furthermore, to accommodate machining and installation errors or to accommodate overlapping parts 1 of different lengths, at least one of the first through hole 121 and the second through hole 211 is an oblong hole. Please refer to [link to relevant documentation]. Figure 4 , Figure 6 and Figure 7 As shown, one of the first through hole 121 and the second through hole 211 is an oblong hole, and the other is a round hole or an oblong hole. In this embodiment, both the second through hole 211 and the first through hole 121 are oblong holes, and the length directions of the first through hole 121 and the second through hole 211 are perpendicular. This arrangement facilitates adjustment of the installation position of the overlapping member 1 and the locking member 2 to accommodate different frame widths and different frame specifications. The perpendicular arrangement of the two oblong holes ensures that the fasteners are stably limited, making the connection more secure. In another embodiment, the first through hole 121 is a round hole, and the second through hole 211 is an oblong hole. The round hole provides a more secure connection, preventing the fasteners 3 from loosening and causing the connection to become unstable.

[0039] Please see Figure 4 and Figure 7 As shown, the hook portion 22 is located on one side of the base portion 21 along its length and is relatively far from the second through hole 211. This arrangement allows the locking member 2 to achieve compatibility with different frame widths with a shorter length, saving material costs.

[0040] Please see Figure 2 and Figure 3As shown, the width of the first plate portion 11 is greater than the width of the top plate portion 1011, and the edge of the width of the first plate portion 11 is attached to the top plate portion 1011. With this arrangement, the contact area between the first plate portion 11 and the top plate portion 1011 is large, so as to ensure the stability of the overlapping member 1, and at the same time, the first plate portion 11 will not block the photovoltaic panel 102 and affect the power generation.

[0041] Please see Figures 2 to 4 As shown, the third plate portion 13 at least partially abuts against the side plate portion 1012, and the length of the third plate portion 13 is greater than the length of the first plate portion 11. With this arrangement, the cable tray assemblies on both sides, through the third plate portion 13 abutting against the transverse side plate portions 1012 of the frame 101, restrict the forward and backward degrees of freedom of the cable tray mechanism, further improving the overall structural stability. In some embodiments, the hook portion 22 of the locking member 2 laterally abuts against the side plate portion 1012, further restricting the forward and backward degrees of freedom of the cable tray mechanism.

[0042] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the first plate portion 11 also includes an extension portion 111, which extends from both ends of the first plate portion 11 along its length and connects to the third plate portion 13. The width of the extension portion 111 is not greater than the width of the top plate portion 1011. This arrangement increases the contact area between the overlapping member 1 and the top plate portion 1011, thereby improving structural strength. In this embodiment, the width edge of the extension portion 111 is flush with the width edge of the third plate portion 13.

[0043] Please see Figure 4 As shown, the width of the second plate portion 12 is greater than the width of the base plate portion 1013, and the edge of the width of the second plate portion 12 is flush with the base plate portion 1013. With this arrangement, the contact area between the second plate portion 12 and the base plate portion 1013 is large, and it does not affect the installation of the locking member 2 and the frame 101. The first plate portion 11 and the second plate portion 12 cooperate to clamp the frame 101 from the top and bottom, thereby restricting the vertical freedom of the cable tray mechanism.

[0044] Please see Figures 1 to 4 As shown, the two locking fasteners 2 at both ends of the overlapping member 1 hook onto the longitudinal frame 101 of the photovoltaic module 10, forming a left-right interlock to restrict the left-right degree of freedom of the cable tray mechanism. Furthermore, since the photovoltaic module 10 is arranged along its width direction, the locking fasteners 2 hook onto the long side of the frame 101 to ensure stable positioning of the photovoltaic module 10 and prevent insufficient positioning from causing separation from the photovoltaic module 10.

[0045] Please see Figure 4 and Figure 5As shown, the base 21 is at least partially attached to the side of the second plate 12 that is away from the bottom plate 1013. With this arrangement, the bottom plate 1013, the second plate 12, and the base 21 are attached in sequence, and the second plate 12 and the base 21 are fixedly connected by fasteners 3, resulting in high overall structural stability.

[0046] Please see Figure 4 , Figure 5 and Figure 7 As shown, the fastener 2 also includes a bent portion 23, which extends from both sides of the edge in the width direction of the base 21 toward a direction away from the overlapping member 1. This arrangement increases the structural strength of the fastener 2 and the connection strength between the fastener 2 and the overlapping member 1.

[0047] In this embodiment, the overlapping member 1 and the locking member 2 are integrally formed by bending metal plates, which has high strength, and thus the cable tray mechanism has high strength.

[0048] In summary, compared with existing technologies, the cable tray mechanism of this utility model has the following advantages: The cable tray mechanism includes a cable tray assembly, which includes an overlapping member 1 and a locking member 2. The two ends of the overlapping member 1 overlap with the frames 101 of two adjacent photovoltaic modules 10, respectively. The locking member 2 includes a base 21 and a hook 22. The base 21 is fixedly connected to one end of the overlapping member 1, and the hook 22 is engaged with the frame 101. This cable tray mechanism solves the problem of the cleaning robot's passage when photovoltaic modules in the same row are disconnected and the purlin fixing holes are occupied. It connects the frames of photovoltaic modules with a simple structure and does not require drilling holes in the frames, thus avoiding damage to the photovoltaic modules.

The understanding of this specification should be based on those skilled in the art.
