Traditional ring main unit (RMU) cabinets have exposed numerous drawbacks over their long-term use. Mismatched interfaces between primary and secondary equipment limit inter-device collaboration, while poor information exchange makes it difficult to quickly and accurately locate faults. These issues not only impact the normal operation of distribution networks but also significantly reduce operational efficiency and increase costs. To address these issues and promote the modernization of distribution networks, outdoor integrated primary and secondary RMU cabinets have emerged as a crucial component for improving distribution network performance.

[0003] The outdoor primary and secondary integrated ring network box has a unique structural design. It mainly consists of a box body, electrical equipment inside the box body, and a door on the box body. The electrical equipment covers primary equipment and secondary equipment. The primary equipment includes load switches, circuit breakers, voltage transformers, current transformers, etc., which are responsible for power transmission and control; the secondary equipment includes intelligent terminals, distribution automation terminals, and power modules, etc., which realize protection, measurement and control, communication and other functions. The box body is divided into multiple compartments such as the switch room, busbar room, cable room, and secondary equipment room to facilitate the orderly installation of different electrical equipment. When installing outdoors, you must first build a cement support base on the ground, and then install the ring network box on the base.

[0004] When outdoor primary and secondary fusion ring mesh cages are used in outdoor environments with a high bird population, they face a thorny problem. Birds excrete during flight, and over time, bird droppings accumulate on the top surface of the ring mesh cage. Bird droppings contain acidic substances that corrode the top surface of the cage, affecting its service life and appearance. To address this issue, the top surface of the cage must be regularly cleaned using specialized cleaning tools. However, due to the high installation height of the ring mesh cage, cleaning personnel face significant challenges, resulting in low cleaning efficiency and high labor and time costs. Improvements to existing technologies are urgently needed. Summary of the Invention

[0009] By adopting the above technical solution, the fixed hooks installed at the four corners of the flexible protective curtain cooperate with the fixed clips set on the end face of the support rod, which can realize the quick and detachable connection between the flexible protective curtain and the support rod. Not only is the installation and disassembly process simple and efficient, it is convenient to replace the flexible protective curtain in time when there are many impurities, and this connection method has a simple structure and is easy to operate, which helps to improve the maintenance efficiency of the outdoor primary and secondary fusion ring network box.

[0010] Optionally, the connecting member is a connecting shaft fixed on the outer periphery of the end of the support rod, and the lower part of the box body relative to the two vertical side surfaces is provided with a guide groove in the horizontal direction for the connecting shaft to be inserted, slide and rotated.

[0023] By adopting the above technical solution, the linkage protrusions on the two end surfaces of the linkage rod cooperate with the linkage slide grooves on the support rod to realize stable sliding of the linkage rod along the length direction of the support rod, ensuring the smoothness and accuracy of the adjustment of the linkage rod; and the fixed through holes on the support rod and the fixed screw holes on the linkage protrusions are connected by fixing bolts, which can reliably lock the sliding state of the linkage rod. The structure is simple and easy to operate, which not only ensures the stability of the linkage rod when it is used in scenarios such as a "ladder", but also facilitates the flexible adjustment of the position of the linkage rod when needed.

[0024] Optionally, the fixing bolt is a butterfly bolt.

[0025] By adopting the above technical solution and the provision of the butterfly bolt, the staff can directly tighten or loosen the fixing bolt manually, which is more efficient.

[0026] In summary, this application has the following beneficial technical effects: A flexible protective curtain is set above the box body and is supported and fixed by a sliding and rotating support rod. When there are a lot of impurities such as bird droppings on the flexible protective curtain, the support rod can be easily slid and rotated to a suitable state, so that the flexible protective curtain can be easily disassembled and replaced. This effectively solves the problem that bird droppings are easily attached to the upper surface of the box body and are difficult to clean when used in outdoor ring network boxes, improves cleaning efficiency, reduces labor costs and time costs, and at the same time ensures the service life and appearance of the ring network box.
