Technical Field

[0001] This utility model relates to a cable tray device and a photovoltaic system, belonging to the field of photovoltaic technology. Background Technology

[0002] The cleaning machine moves across the photovoltaic modules to perform cleaning. There is a gap between adjacent photovoltaic arrays, approximately 100-200mm. To facilitate the operation of the cleaning machine, a cable tray structure needs to be installed at the gap.

[0003] In related technologies, the cable tray structure includes a snap-fit ​​part and an edge-wrapping part. The snap-fit ​​part snaps into the frame of the photovoltaic array, and the edge-wrapping part bends and extends relative to the snap-fit ​​part to wrap around a portion of the frame. However, the cable tray structure is prone to translation along the length of the frame, resulting in unstable installation. Utility Model Content

The third plate, the fourth plate, the fifth plate, the sixth plate and the second side plate together form the second buckle groove, and the third plate and the second plate have the same structure.

[0010] As a further improvement of the present invention, the fifth plate is provided with a first protrusion on the side away from the second side plate, and the sixth plate is provided with a second protrusion on the side away from the second side plate.

[0030] Please refer to Figures 1 to 10 As shown, this utility model discloses a photovoltaic system, including at least two photovoltaic arrays 10 and a bridge device 20. There is a gap 100 between two adjacent photovoltaic arrays 10, and the bridge device 20 is disposed at the gap 100 and connects the two adjacent photovoltaic arrays 10. This arrangement facilitates the passage of the sweeper's wheel diameter.

[0031] Please refer to Figure 2 As shown, each photovoltaic array 10 includes a frame 101 and a photovoltaic panel 102 mounted on the frame 101. The bridge device 20 is connected to the frames 101 of two adjacent photovoltaic arrays 10.

[0032] Please refer to Figure 2 and Figure 3 As shown, the cable tray assembly 20 includes a cable tray 1 and a limiting mechanism 2 connected to the cable tray 1. The cable tray 1 is made of aluminum alloy and is formed in one piece using a casting process. The use of aluminum alloy gives the cable tray 1 the characteristics of being lightweight, having high mechanical strength, and being low in cost.

[0033] Please refer to Figures 4 to 6As shown, the cable tray 1 includes a first latching part 11 and a second latching part 12 connected to the first latching part 11. The first latching part 11 engages with the frame 101 of the photovoltaic array 10, thereby connecting the cable tray 1 to the photovoltaic array 10. The cable tray 1 has a simple structure and is easy to install. Correspondingly, the first latching part 11 has a first slot 110 for accommodating the frame 101 of the photovoltaic array 10. A limiting mechanism 2 engages with the second latching part 12 and abuts against the frame 101. The second latching part 12 has a second slot 120, and the limiting mechanism 2 is located in the second slot 120. By setting the limiting mechanism 2 to abut against the frame 101, the cable tray 1 is prevented from shifting along its length, ensuring that the cable tray device 20 is installed securely and stably connects the adjacent photovoltaic array 10.

[0034] In the embodiments illustrated in this application, such as Figure 3 As shown, two sets of limiting mechanisms 2 are provided. The two sets of limiting mechanisms 2 abut against the inner edges of the frame 101 of the two adjacent photovoltaic arrays 10 respectively, to prevent the cable tray 1 from moving relative to the frame 101.

[0035] In some embodiments, the first latching part 11 is bonded and fixed to the frame 101, so that the connection between the cable tray 1 and the frame 101 is stable. Of course, in other possible embodiments, the first latching part 11 is fixed to the frame 101 by fasteners, which facilitates the disassembly of the first latching part 11.

[0036] For details, please refer to Figures 4 to 6 As shown, the first latching part 11 includes a first plate 111, a second plate 112 opposite to the first plate 111, and a first side plate 113 connecting the first plate 111 and the second plate 112. The first plate 111, the second plate 112, and the first side plate 113 together form a first latching groove 110. In the embodiment illustrated in this application, along the thickness direction of the first side plate 113, the length of the second plate 112 is greater than the length of the first plate 111, thereby increasing the contact area between the second plate 112 and the frame 101.

[0037] Please refer to Figures 4 to 6 As shown, the first plate 111 abuts against the top of the frame 101, and the second plate 112 abuts against the bottom of the frame 101. The opposing surfaces of the first plate 111 and the second plate 112 are provided with anti-slip textures 1110 for anti-slip purposes. During manufacturing, several long grooves extending along the length of the first plate 111 and the second plate 112 are provided, thus creating an uneven texture on the surfaces of the first plate 111 and the second plate 112, thereby achieving an anti-slip effect. The first side plate 113 is bonded and fixed to the side of the frame 101 or fixed with fasteners. Specifically, the inner side of the first side plate 113 is provided with two parallel protrusions 1131, which form an adhesive groove 1130 for accommodating the adhesive layer.

[0038] Please refer to Figure 5 and Figure 6 As shown, the second latching part 12 includes a third plate 121, a fourth plate 122 opposite to the third plate 121, a second side plate 123 connecting the third plate 121 and the fourth plate 122, a fifth plate 124 perpendicularly connected to the third plate 121, and a sixth plate 125 perpendicularly connected to the fourth plate 122. The fifth plate 124 and the sixth plate 125 are arranged opposite to each other, and the third plate 121, the fourth plate 122, the fifth plate 124, the sixth plate 125, and the second side plate 123 together form a second latching groove 120. The third plate 121 and the second plate 121 have the same structure.

[0039] Please refer to the embodiments illustrated in this application. Figures 5 to 8 As shown, the fifth plate 124 has a first protrusion 1241 on the side away from the second side plate 123, and the sixth plate 125 has a second protrusion 1251 on the side away from the second side plate 123. The limiting mechanism 2 can compress the first protrusion 1241 and the second protrusion 1251, thereby limiting the deformation of the first protrusion 1241 and the second protrusion 1251 by compression. The cross-sections of the first protrusion 1241 and the second protrusion 1251 can both be triangular to facilitate compression deformation by the limiting mechanism 2. The cross-sections of the first protrusion 1241 and the second protrusion 1251 can also be other easily deformable shapes under compression, and are not limited to triangles here.

[0040] Please refer to Figures 3 to 10 As shown, the limiting mechanism 2 includes a limiting member 21, a T-bolt 22, and a nut 23. The limiting member 21 has a through hole 210 for the T-bolt 22 to pass through. The T-bolt 22 is installed in the second slot 120 and the limiting member 21 is locked by the nut 23. The limiting member 21 is used to abut against the inner edge of the frame 101. During installation, the T-bolt 22 tightens and rotates to press the opening of the second slot 120, and the slight deformation of the opening further tightens the mechanism.

[0041] For details, please refer to Figures 7 to 10 As shown, the limiting member 21 includes a limiting part 211 and a boss 212 connected to the limiting part 211. A through hole 210 passes through the limiting part 211 and the boss 212. The boss 212 extends into the second slot 120 and abuts against the fifth plate 124 and the sixth plate 125, thus playing a limiting role and making the connection between the limiting mechanism 2 and the cable tray 1 more stable.

The understanding of the present utility model should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model.
