Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, and in particular to a connection structure for a photovoltaic power generation transmission cable. Background Technology

[0002] Photovoltaic power generation systems are widely used in various energy production and utilization processes. They convert solar energy into electricity using solar panels to supply homes, businesses, or the power grid. In photovoltaic systems, cables are used to connect the photovoltaic panels to inverters and other equipment to ensure stable power transmission. To ensure the safe and stable operation of the power system, the design of the cable connection structure is particularly important, especially the cable connection method and the heat dissipation performance of the cable junction box, which directly affects the system efficiency and equipment lifespan.

[0003] In existing photovoltaic (PV) systems, cable access cabinets are typically located at a specific point in the system, transmitting power through connections to inverters or solar panels. While existing cable access structures provide basic electrical connections, the cabinets and their internal equipment generate significant heat during prolonged operation or high-load operation. This heat accumulation can lead to overheating, affecting the stability and safety of the PV system. Existing cable access cabinets generally employ a sealed design to prevent external contaminants from entering, but this also hinders effective heat dissipation. Many cable access cabinets lack effective heat dissipation mechanisms, failing to effectively dissipate the heat generated within, especially in high-temperature environments, potentially causing overheating, malfunctions, or even damage to the equipment. Therefore, we provide a new cable access structure for PV power generation. Utility Model Content

[0018] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below. Example

[0019] like Figures 1-3 As shown, this utility model provides a technical solution: a transmission cable access structure for photovoltaic power generation, including: a base mechanism 1, the base mechanism 1 including a fixed base 11, an adjustment frame 12 provided on the fixed base 11, a fixing pin 13 provided on the adjustment frame 12, and a cabinet mechanism 2 provided on the adjustment frame 12. Cabinet mechanism 2 includes cable docking cabinet 21. Both sides of the cable docking cabinet 21 are provided with flip adjustment frame 22. The flip adjustment frame 22 is provided with gear disk 23. The flip adjustment frame 22 is provided with flip cover plate 24. The cable docking cabinet 21 is provided with exhaust fan 25. One side of the cable docking cabinet 21 is provided with flip door panel 26. One end of the adjusting frame 12 is welded to the fixed base 11. The base of the cable docking cabinet 21 is nested and docked in the adjusting frame 12. The outer surface of the fixing pin 13 passes through the adjusting frame 12 to fix the cable docking cabinet 21 by means of threaded rotation. One end of the flip adjusting frame 22 is welded to the cable docking cabinet 21. The inner surface of the gear disk 23 is welded to the flip adjusting frame 22. One end of the flip cover 24 is welded to the flip adjusting frame 22. One end of the exhaust fan 25 is docked inside the cable docking cabinet 21. One side of the flip door panel 26 is docked to the cable docking cabinet 21.

[0020] In this embodiment, when the staff uses this cable cabinet to connect photovoltaic cables, they can extend the photovoltaic cables to be connected from the bottom of the cable connection cabinet 21 into the inside of the cable connection cabinet 21 and connect them with the working equipment inside the cable connection cabinet 21. The working equipment will generate a certain amount of heat during actual operation. The staff can control the exhaust fan 25 in the cable connection cabinet 21 to operate. During the operation of the exhaust fan 25, the air pressure will blow the flip cover 24 to exhaust the heat from both sides of the cable connection cabinet 21. When the exhaust fan 25 stops working, the flip cover 24 covers the cable connection cabinet 21, thereby improving its practicality in actual use. Example

[0021] like Figures 1-4 As shown, both sides of the cable docking cabinet 21 are provided with adjustment mechanisms 3. The adjustment mechanism 3 includes an extension plate 31, a working motor 32 is provided on the extension plate 31, a double-rail rack 33 is provided at one end of the working motor 32, a docking plate 34 is provided at one end of the double-rail rack 33, a top cover plate 35 is provided at one end of the docking plate 34, and a balance adjustment rod 36 is provided at the bottom of the top cover plate 35. One end of the expansion plate 31 is welded to the cable docking cabinet 21, one end of the working motor 32 is welded to the expansion plate 31, one end of the double-rail rack 33 is docked to the working motor 32, the outer surface of one end of the double-rail rack 33 is engaged in the docking plate 34, one end of the docking plate 34 is welded to the top cover plate 35, and one end of the balance adjustment rod 36 is welded to the bottom of the top cover plate 35.

[0022] In this embodiment, to further enhance its practicality in actual use, corresponding adjustment mechanisms 3 are provided on both sides of the cable docking cabinet 21. Workers can weld one end of the expansion plate 31 to the cable docking cabinet 21 and one end of the working motor 32 to the expansion plate 31. Then, by controlling the working motor 32 to drive the double-rail rack 33 to rotate, the docking plate 34 and gear disk 23 on the outer surface of the double-rail rack 33 can be raised and lowered by the working of the double-rail rack 33. This allows the top cover plate 35 to be raised and lowered for protection of the top of the cable docking cabinet 21, thereby further improving its safety in actual use.

[0023] Working principle: like Figures 1-4 As shown, when staff use this cable cabinet to connect photovoltaic cables, they first need to introduce the photovoltaic cable to be connected from the bottom of the cable docking cabinet 21 and extend the cable into the cabinet to connect with the working equipment inside the cable docking cabinet 21. Since the working equipment generates heat during operation, staff can activate the exhaust fan 25 inside the cable docking cabinet 21 for heat dissipation. When the exhaust fan 25 starts operating, the air pressure pushes the flip cover 24, effectively expelling the heat generated inside the cable docking cabinet 21 through both sides of the cabinet, thus preventing equipment malfunction due to overheating. When the exhaust fan 25 stops working, the flip cover 24 automatically closes, restoring the cover to the cable docking cabinet 21, further ensuring the safety and stability of the equipment. This heat dissipation and protection mechanism significantly improves the practicality and reliability of the cable cabinet in actual use.

[0024] To further enhance the safety and flexibility of the cable cabinet during operation, adjustment mechanisms 3 are installed on both sides of the cable docking cabinet 21. Operators can weld one end of the extension plate 31 to the side of the cable docking cabinet 21 and one end of the working motor 32 to the extension plate 31, forming a stable mechanical structure. By controlling the working motor 32, operators can rotate the double-rail rack 33, causing its outer surface to cooperate with the docking plate 34 and the gear disc 23, thereby adjusting the height of the top cover 35. Through this adjustment mechanism, operators can flexibly adjust the position of the protective top cover 35 on the top of the cable docking cabinet 21 as needed, achieving height control of the top protection function of the cabinet and further enhancing the protective performance of the equipment.

[0025] This adjustment mechanism not only facilitates quick adjustments by staff according to actual work needs, but also enhances the adaptability of the cable cabinet in different working environments. In high-temperature or special environments, staff can adjust the lifting and lowering of the cover to provide additional protection for the equipment, ensuring that it is not affected by the external environment during operation, and improving the long-term stability and safety of the equipment.
