A photovoltaic cable tray with heat dissipation holes

Abstract

This utility model provides a photovoltaic cable tray with heat dissipation holes, relating to the field of photovoltaic cable tray technology. It includes a base plate, a top plate, and heat dissipation holes. A connecting mechanism is provided between the base plate and the top plate. Multiple limiting mechanisms are equidistantly arranged inside the base plate. This utility model allows the upper clamping plate to be pulled upwards, increasing the gap between the lower and upper clamping plates, allowing the photovoltaic cable to pass through. At this point, the cable is compressed. Then, releasing the clamping plate utilizes the spring force to move it downwards, clamping the photovoltaic cable and limiting its movement. An adjusting nut can be screwed down to slide downwards on the outside of the first threaded rod, adjusting the spring compression to increase the clamping force of the upper clamping plate and improve the limiting effect on the photovoltaic cable. This ensures the photovoltaic cables are equidistantly arranged inside the base plate, solving the problem in existing technologies where multiple cables need to be connected to a junction box, leading to cable tangling.

Technical Field

[0001] This utility model relates to the field of photovoltaic cable tray technology, and in particular to a photovoltaic cable tray with heat dissipation holes. Background Technology

[0002] Photovoltaic cable trays are cable support systems specifically designed for photovoltaic power plants. They adopt trough, ladder, or tray structures and are mostly made of hot-dip galvanized steel, aluminum alloy, or stainless steel. They are characterized by corrosion resistance, moisture resistance, and high strength. The cable tray design takes into account cable laying, protection, and environmental adaptability, ensuring the safe and stable operation of cables. At the same time, they are easy to maintain and manage, making them an indispensable infrastructure for photovoltaic power plants. During the installation of cables in photovoltaic cable trays, multiple cables need to be connected to junction boxes, which can easily lead to cables becoming tangled. Later, it is difficult for staff to organize the cables during maintenance and debugging. Therefore, this utility model proposes a photovoltaic cable tray with heat dissipation holes to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a photovoltaic cable tray with heat dissipation holes to solve the problem in the prior art where multiple cables need to be connected to the junction box, which leads to the cables easily becoming tangled.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a photovoltaic cable tray with heat dissipation holes, including a base plate, a top plate and heat dissipation holes, the top plate is provided on the top of the base plate, the interior of the base plate and the top plate are provided with multiple heat dissipation holes, a connecting mechanism is provided between the base plate and the top plate, and multiple limiting mechanisms are provided at equal intervals inside the base plate.

[0005] A further improvement is made in that: the limiting mechanism includes a lower clamping plate, an upper clamping plate, a first threaded rod, a spring, and an adjusting nut. Multiple lower clamping plates are equidistantly arranged inside the base plate. A first threaded rod is symmetrically fixedly connected to both ends of the lower clamping plate. An upper clamping plate is inserted into the outer side of the first threaded rod. A spring is provided on the outer side of the first threaded rod. An adjusting nut is threadedly connected to the top end of the first threaded rod.

[0006] A further improvement is that: the bottom of the base plate is fixedly connected to multiple sets of insert rods, the top of the insert rods is fixedly connected to a fixing bolt, the two ends of the lower clamping plate are symmetrically provided with connecting holes, and the top of the fixing bolt passes through the interior of the connecting hole and is threaded with a fixing nut.

[0007] A further improvement is made in that: the connecting mechanism includes a fixing nut and a guide rod; a set of fixing nuts is symmetrically fixedly connected to both sides of the top plate; two sets of guide rods are symmetrically fixedly connected to both sides of the bottom plate; the top end of the guide rod extends through the interior of the fixing nut; and the fixing nut is detachably connected to the bottom plate by a connecting bolt.

[0008] A further improvement is that both the bottom plate and the top plate are rectangular structures, and the inner wall of the top plate is interlocked with the outer wall of the bottom plate. Both the bottom plate and the top plate are made of hot-dip galvanized steel.

[0009] A further improvement is that the bottom plate and the top plate form a rectangular frame structure, which is wrapped around the photovoltaic cable, and a fixing mechanism is provided between adjacent rectangular frames.

[0010] A further improvement is made in that: the fixing mechanism includes a positioning plate, a second threaded rod, a clamping plate, a locking rod, and an end cap. The bottom of the base plate is fitted with the positioning plate, the top of the positioning plate is fixedly connected with the second threaded rod, the top of the second threaded rod is inserted with the clamping plate, and a set of locking rods are symmetrically fixedly connected to both sides of the clamping plate and the positioning plate. The bottom end of the locking rod is inserted into the heat dissipation hole, and the top of the second threaded rod is threadedly connected with the end cap.

[0011] The beneficial effects of this utility model are as follows: Pulling the upper clamping plate upward increases the gap between the lower clamping plate and the upper clamping plate, allowing the photovoltaic cable to pass through. At this time, the cable is in a compressed state. Then, releasing the clamping plate utilizes the elastic force generated by the spring to move the upper clamping plate downward and clamp the photovoltaic cable, thereby limiting the position of the photovoltaic cable. The adjusting nut can be turned and slid downward on the outside of the first threaded rod to adjust the compression degree of the spring, making the clamping force of the upper clamping plate greater and the limiting effect on the photovoltaic cable better. This allows the photovoltaic cables to be arranged equidistantly inside the base plate, solving the problem in the prior art where multiple cables need to be connected to the junction box, which leads to the cables easily becoming tangled.

Detailed Implementation

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a photovoltaic cable tray with heat dissipation holes, including a base plate 1, a top plate 2, and heat dissipation holes 3. The top plate 2 is provided on the top of the base plate 1. Both the base plate 1 and the top plate 2 have multiple heat dissipation holes 3 inside. A connecting mechanism is provided between the base plate 1 and the top plate 2. Multiple limiting mechanisms are provided at equal intervals inside the base plate 1. The photovoltaic cables are arranged at equal intervals on the bottom of the base plate 1 through the limiting mechanisms. Then, the top plate 2 is snapped onto the top of the base plate 1. The connecting mechanism connects the top plate 2 and the base plate 1 into one unit to wrap the photovoltaic cable tray and protect it.

[0016] The limiting mechanism includes a lower clamping plate 4, an upper clamping plate 5, a first threaded rod 6, a spring 7, and an adjusting nut 8. Multiple lower clamping plates 4 are equidistantly arranged inside the base plate 1. A first threaded rod 6 is symmetrically fixed to both ends of each lower clamping plate 4. An upper clamping plate 5 is inserted into the outer side of the first threaded rod 6, and a spring 7 is located on the outer side of the first threaded rod 6. An adjusting nut 8 is threadedly connected to the top of the first threaded rod 6. Pulling the upper clamping plate 5 upwards increases the gap between the lower clamping plate 4 and the upper clamping plate 5, allowing the photovoltaic cable to pass through. At this time, the cable is in a compressed state. Then, releasing the clamping plate utilizes the elastic force generated by the spring 7 to move the upper clamping plate 5 downwards, clamping the photovoltaic cable and limiting its movement. The adjusting nut 8 can be turned and slid downwards on the outer side of the first threaded rod 6 to adjust the compression degree of the spring 7, resulting in a greater clamping force of the upper clamping plate 5 and a better limiting effect on the photovoltaic cable, ensuring that the photovoltaic cables are equidistantly arranged inside the base plate 1.

[0017] The bottom of the base plate 1 is fixedly connected to multiple sets of insert rods 10. The top of each insert rod 10 is fixedly connected to a fixing bolt 11. The two ends of the lower clamping plate 4 are symmetrically provided with connecting holes 9. The top of the fixing bolt 11 passes through the interior of the connecting hole 9 and is threaded with a fixing nut 12. The fixing bolt 11 at the top of the insert rod 10 passes through the interior of the connecting hole 9. The two sides of the lower clamping plate 4 are respectively attached to the top of the insert rod 10. The fixing nut 12 is tightened on the top of the fixing bolt 11. The fixing nut 12 can clamp the two sides of the lower clamping plate 4 to fix the lower clamping plate 4 to the inside of the base plate 1.

[0018] The connecting mechanism includes fixing nuts 12 and guide rods 13. A set of fixing nuts 12 are symmetrically fixedly connected to both sides of the top plate 2, and two sets of guide rods 13 are symmetrically fixedly connected to both sides of the bottom plate 1. The top end of the guide rod 13 extends through the interior of the fixing nut 12. The fixing nut 12 is detachably connected to the bottom plate 1 by connecting bolts, which engages the top plate 2 on the outside of the bottom plate 1. The guide rods 13 on both sides of the bottom plate 1 extend through the interior of the fixing nut 12, and the fixing nut 12 is then connected to the bottom plate 1 as a whole by connecting bolts, thereby fixing the top plate 2 to the top of the bottom plate 1. The top plate 2 and the bottom plate 1 form a rectangular structure that wraps around the photovoltaic cable, providing protection for it.

[0019] Both the base plate 1 and the top plate 2 are rectangular structures, and the inner wall of the top plate 2 is interlocked with the outer wall of the base plate 1. Both the base plate 1 and the top plate 2 are made of hot-dip galvanized steel. Hot-dip galvanized steel cable trays have excellent corrosion resistance. The galvanized layer on the surface can effectively resist the erosion of environmental factors such as atmosphere and water, extending the service life of the cable tray. At the same time, it also has the characteristics of high strength and strong load-bearing capacity, making it suitable for various complex environments.

[0020] The base plate 1 and top plate 2 form a rectangular frame structure, which is used to wrap the photovoltaic cable. A fixing mechanism is provided between adjacent rectangular frames. The fixing mechanism includes a positioning plate 14, a second threaded rod 15, a clamping plate 16, a locking rod 17, and an end cap 18. The positioning plate 14 is attached to the bottom of the base plate 1. The second threaded rod 15 is fixedly connected to the top of the positioning plate 14. The clamping plate 16 is inserted into the top of the second threaded rod 15. A set of locking rods 17 are symmetrically fixed to both sides of the clamping plate 16 and the positioning plate 14. The bottom end of the locking rod 17 is inserted into the heat dissipation hole 3. The second threaded rod 15... The top is threaded with an end cap 18. Bring one end of the two cable trays close to each other, place the positioning plate 14 between the two cable trays, and have the locking rods 17 on both sides of the positioning plate 14 pass through the heat dissipation holes 3 at the bottom of the two base plates 1 respectively. Insert the clamping plate 16 into the top of the second threaded rod 15, press the clamping plate 16 down, and have the locking rods 17 on both sides of the clamping plate 16 pass through the heat dissipation holes 3 at the top of the two top plates 2 respectively. Then tighten the top end cap 18 at the top of the second threaded rod 15. The end cap 18 clamps the clamping plate 16, the top plate 2, the base plate 1 and the positioning plate 14 together to connect the two cable trays into one unit.

[0021] This photovoltaic cable tray, when the upper clamping plate 5 is pulled upward, increases the gap between the lower clamping plate 4 and the upper clamping plate 5, allowing the photovoltaic cable to pass through. At this time, the cable is in a compressed state. Then, when released, the elastic force generated by the spring 7 drives the upper clamping plate 5 downward to clamp the photovoltaic cable, thereby limiting the photovoltaic cable. The adjusting nut 8 can be turned and slid downward on the outside of the first threaded rod 6 to adjust the compression degree of the spring 7, so that the clamping force of the upper clamping plate 5 is greater and the limiting effect on the photovoltaic cable is better. This allows the photovoltaic cables to be arranged equidistantly inside the base plate 1, solving the problem in the prior art that multiple cables need to be connected to the junction box, which leads to the cable being easily scattered.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
