Description

Technical Field

[0001] This utility model relates to the field of cable wiring technology, specifically a concealed wiring structure for a distributed photovoltaic power station. Background Technology

[0002] Concealed wiring in distributed photovoltaic (PV) power stations is an advanced technology that cleverly utilizes the space within the building structure to lay the connecting lines between PV modules, the DC cables from the DC combiner box to the inverter, and even some AC cables. It abandons the traditional method of exposed cable trays or overhead cables, and instead hides the cables in concealed locations such as under the frame of the PV modules, inside the clamps, between the roof purlins, in the wall cavities of the building, above the ceiling, and in reserved pipe shafts. Its core purpose is to maximize the aesthetics of the power station and make the PV system blend perfectly with the building roof or facade.

[0003] Authorization announcement number CN223093400U discloses a concealed cable wiring structure for a distributed photovoltaic power station. The technical solution is as follows: "It includes: a wiring conduit, with multiple limiting blocks fixedly connected to both sides inside the wiring conduit, and a limiting groove formed on one side of each of the multiple limiting blocks opposite to each other. Multiple limiting posts are fixedly connected to both sides inside the wiring conduit." The beneficial effect is that: after the cable passes through the multiple pressing and fixing blocks until the cable threading is completed, the locking block between the pulling block and the outer wall of the wiring conduit is removed, causing the pressing and fixing blocks to move to one side of the cable under the action of spring force, pressing the cable tightly against the inner wall of the wiring conduit, thus fixing the cable.

[0004] The above-mentioned technical solution has the following drawbacks. While the structure improves the overall aesthetics and protection by centrally hiding the cables through wiring conduits, the conduits are an integral design that is difficult to disassemble. When the cables need maintenance, the entire conduit must be removed or its structure damaged to access the internal cables, increasing maintenance difficulty and operation time. Furthermore, the integral wiring conduits lack flexibility in handling local cable faults or when adding or removing lines, making it impossible to perform targeted repairs or partial replacements. This leads to increased operation and maintenance costs and reduces the maintainability and scalability of the distributed photovoltaic power station system. Therefore, a concealed wiring structure for distributed photovoltaic power stations is proposed to solve the problems mentioned above. Utility Model Content
