Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a naturally air-cooled mountain photovoltaic cable tray. Background Technology

[0002] Mountain photovoltaic power stations have become an important direction for the development of the photovoltaic industry due to their efficient use of idle mountain resources. Among them, photovoltaic cable trays are important facilities used for cable laying and protection in photovoltaic power stations. The quality of installation and construction directly affects the operating efficiency and safety of photovoltaic power stations.

[0003] Patent CN222441292U discloses a cable tray for mountain photovoltaic projects that facilitates on-site construction. In use, different types of support bases are selected according to the specifications of the cable body, followed by a matching cover plate to facilitate the use of the clamping device. A cover plate is fixedly installed on the outside of the base, and a clamping device is fixedly installed at the bottom of the cover plate, located above the protective device. The cable body is placed inside the placement platform, and a spring in the clamping device drives the clamping block to clamp the upper part of the cable body. After the first support rod is fixed, the position of the second support rod is adjusted by moving the moving block, thereby fixing the second support rod. However, the above device has the following drawbacks: during the transmission of electrical energy, the photovoltaic cable continuously generates heat due to its own resistance, and the enclosed structure blocks the effective flow of heat to the outside air, causing heat to continuously accumulate inside the device.

[0004] Therefore, how to optimize the cable tray structure design to enhance the natural air cooling effect and dissipate the heat of the cable operation has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0028] 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.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-2 This utility model provides a natural air-cooled mountain photovoltaic cable tray, including a box body 1 with openings at the top, front, and rear ends. The openings at the front and rear ends are designed for cables to pass through and out along the length of the box body 1. Ventilation holes 2 are provided on the opposite side walls of the box body 1. The ventilation holes 2 are louvered ventilation holes 2.

[0031] Reference Figures 2-3 The lid 3 is located at the top of the box body 1.

[0032] The upper end of the lid 3 is symmetrically provided with a sloping surface 17, which can guide rainwater to flow to both sides of the lid 3.

[0033] The side walls opposite to the lid 3 are provided with extension plates 18. The upper surface of the extension plate 18 is flush with the upper surface of the slope surface 17. The extension plate 18 and the slope surface 17 are integrally formed. The extension plate 18 further expands the rainproof coverage of the lid 3, enhances the overall rainproof effect, and prevents rainwater from entering from the connection gap between the box body 1 and the lid 3.

[0034] Reference Figure 2 The box 1 has two first fixing plates 4 arranged opposite each other along the length direction, and a set of two opposite first fixing plates 4 arranged along the width direction. Four first fixing plates 4 are fixedly connected inside the box 1. The four first fixing plates 4 are arranged diagonally. The box 1 can hold two cables.

[0035] Reference Figure 3 The lower end of the box cover 3 is provided with a second fixing plate 5 that corresponds one-to-one with the first fixing plate 4.

[0036] Both the first fixing plate 4 and the second fixing plate 5 have arc-shaped placement grooves 6 on their opposite sidewalls. The curvature of the arc-shaped placement grooves 6 matches the outer diameter of the photovoltaic cable. During installation, the cable is placed in the arc-shaped placement groove 6 of the first fixing plate 4, and then the cover 3 is closed, so that the arc-shaped placement groove 6 of the second fixing plate 5 fits against the upper surface of the cable, thereby fixing the cable between the arc-shaped placement grooves 6 of the first fixing plate 4 and the second fixing plate 5.

[0037] Reference Figure 2 Inside the box 1, there are two support rods 7 connected along the length direction. The number of support rods 7 is not specifically limited and can be one or more. The two support rods 7 are located between two first fixing plates 4 that are arranged opposite each other along the length direction. The upper end of the support rod 7 abuts against the side wall of the cable.

[0038] To increase the contact area between the support rod 7 and the cable, an arc-shaped support bracket 8 is fixedly connected to the upper end of the support rod 7. The support bracket 8 abuts against the side wall of the cable, and the curvature of the support bracket 8 is also adapted to the outer diameter of the cable.

[0039] The cable is fixed at both ends of the box body 1 and the box cover 3 by the first fixing plate 4 and the second fixing plate 5. The middle part of the cable does not contact the box body 1 and the box cover 3. The lower surface of the middle part of the cable is supported by the support rod 7 and the support bracket 8. A gap is left between the cable and the box body 1 and the box cover 3 for air circulation.

[0040] Reference Figure 2 , Figure 3 and Figure 5 Each of the opposite side walls of the box body 1 is provided with two connecting holes 9. The side wall of the box cover 3 facing the box body 1 is provided with locking holes 10 that correspond one-to-one with the connecting holes 9. A self-locking component is provided in the locking hole 10. The self-locking component selectively extends into or out of the connecting hole 9, thereby realizing the locking and unlocking of the box cover 3 and the box body 1.

[0041] The locking hole 10 is convex. The self-locking assembly includes a locking block 11 and a first spring 12. The longitudinal section of the locking block 11 is T-shaped. The locking hole 10 is adapted to the locking block 11. The first spring 12 is arranged inside the locking hole 10. The two ends of the first spring 12 are fixedly connected to one end of the locking block 11 and the right side wall of the locking hole 10, respectively. The other end of the locking block 11 selectively extends into or out of the connecting hole 9. In the natural state, the first spring 12 is in a naturally extended state, pushing the other end of the locking block 11 out of the locking hole 10 and into the connecting hole 9 on the side wall of the box body 1. At this time, the box cover 3 and the box body 1 are locked and fixed. When the lid 3 needs to be opened, simply apply external force to the locking block 11 to compress the first spring 12, causing the other end of the locking block 11 to extend out of the connecting hole 9, thus unlocking the box. In addition, the lower end of the other end of the locking block 11 is provided with a slope 13. When the lid 3 is closed, the upper edge of the box body 1 contacts the slope 13. As the lid 3 is pressed down, the edge of the box body 1 generates a lateral pushing force on the slope 13, pushing the locking block 11 to compress the first spring 12 and retract into the locking hole 10. When the lid 3 is fully closed, the locking hole 10 is aligned with the connecting hole 9, the first spring 12 returns to its natural extended state, and pushes the locking block 11 into the connecting hole 9, completing the automatic locking without the need for additional manual operation of the locking block 11.

[0042] The side wall of the lid 3 away from the box body 1 is provided with an insertion hole 14 that corresponds one-to-one with the locking hole 10. The insertion hole 14 is slidably connected to the connecting rod 15. The two ends of the connecting rod 15 are fixedly connected to the locking block 11 and the pull ring 16 respectively. The first spring 12 is sleeved on the periphery of the connecting rod 15, and the pull ring 16 is located outside the box body 1.

[0043] When it is necessary to open the box cover 3, the operator only needs to pull the pull ring 16 outward. The pull ring 16 drives the locking block 11 to move into the locking hole 10 through the connecting rod 15, compressing the first spring 12, so that the locking block 11 extends out of the connecting hole 9, and the box cover 3 can be removed from the box body 1.

[0044] Reference Figure 2 and Figure 4 A connecting plate 19 is provided on the left side of the box body 1, and a connecting groove 20 adapted to the connecting plate 19 is provided on the right side of the box body 1. A mounting hole 21 is provided on the connecting plate 19, and a second spring 22 is arranged in the mounting hole 21. The two ends of the second spring 22 are fixedly connected to the bottom of the mounting hole 21 and the positioning rod 23, respectively. The positioning rod 23 is slidably connected to the mounting hole 21. A through hole 24 corresponding to the mounting hole 21 is provided at the upper end of the connecting groove 20. The through hole 24 of the adjacent device is selectively connected to the positioning rod 23. The through hole 24 is misaligned with the first fixing plate 4 to avoid interference between the positioning rod 23 and the first fixing plate 4 during the insertion of the through hole.

[0045] The positioning rod 23 is pushed to retract into the mounting hole 21, compressing the second spring 22; when the connecting plate 19 is fully inserted into the connecting groove 20, the mounting hole 21 is aligned with the through hole 24, the second spring 22 returns to its natural extended state, pushes the positioning rod 23 out of the mounting hole 21 and inserts it into the through hole 24, thereby fixing the two adjacent boxes 1.

[0046] Reference Figures 1-2 The box body 1 has a fixing groove 25 on the opposite side wall. A dustproof plate 26 is slidably connected in the fixing groove 25. The dustproof plate 26 is arranged opposite to the ventilation hole 2. The box body 1 is connected to the ground through a support frame. The support frame is welded from angle steel. The box body 1 and the support frame are connected by bolts.

[0047] The working principle of this utility model is as follows: In use, first adjust the height of the support frame according to the mountainous terrain and fix it to the ground. Then connect the box 1 to the support frame, ensuring that the box 1 is level. During installation, align the connecting plate 19 on the left side of the preceding box 1 with the connecting groove 20 on the right side of the following box 1 and push it in. During the pushing process, squeeze the positioning rod 23, causing it to retract into the mounting hole 21 and compress the second spring 22. After the connecting plate 19 is fully inserted, the mounting hole 21 aligns with the through hole 24. The second spring 22 resets and pushes the positioning rod 23 into the through hole 24, completing the fixing of adjacent box 1.

[0048] Next, two photovoltaic cables are inserted through the front and rear openings of the box 1 and placed in the arc-shaped placement slots 6 of the four diagonally opposite first fixing plates 4. The arc-shaped support brackets 8 at the upper ends of the two support rods 7 inside the box 1 abut against the side walls of the cables. Then, the box cover 3 is closed, so that the second fixing plate 5 corresponds to the first fixing plate 4. When the box cover 3 is pressed, the edge of the box 1 contacts the lower inclined surface 13 of the locking block 11, pushing the locking block 11 into the locking hole 10 and compressing the first spring 12. After the box cover 3 is fully closed, the arc-shaped placement slots 6 of the second fixing plate 5 fit against the upper surface of the cable, the locking hole 10 aligns with the connecting hole 9, and the first spring 12 resets, pushing the locking block 11 into the connecting hole 9, completing the locking and cable fixing work.

[0049] During operation, the louvered ventilation holes 2 provide ventilation, and air flows through the gaps between the cable and the box body 1 and the box cover 3 to dissipate heat from the cable. The dustproof plate 26 filters dust. During maintenance, pulling the pull ring 16 will cause the locking block 11 to retract into the locking hole 10 via the connecting rod 15, thus opening the box cover 3. After maintenance, the cover can be closed.
