Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cable protection, in particular to a photovoltaic cable protection device. Background Art

[0002] Photovoltaic power generation systems, abbreviated as PV, refer to power generation systems that utilize the photovoltaic effect of photovoltaic cells to directly convert solar radiation into electrical energy. PV power generation systems are categorized as standalone PV systems and grid-connected PV systems. PV power generation systems consist of solar cell arrays, battery banks, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems, and other equipment. These devices are connected by cables. However, the connecting equipment between PV systems is installed remotely, and the connecting cables span long distances. Some cables are exposed to the ground, making them susceptible to corrosion from sunlight and rain, reducing their service life and affecting the normal operation of the PV system. Furthermore, multiple cables can easily become tangled, making them difficult to distinguish.

[0003] The patent document with publication number CN217135445U discloses a cable protection and separation device for photovoltaics, including a cable and a protective wire box, wherein the protective wire box is embedded with multiple cables, and an upper protective cover is embedded and installed on the top of the protective wire box for sealing, multiple connecting ears are connected to the front and rear ends of the protective wire box, and multiple drainage grooves are evenly opened on the bottom of the protective wire box, and multiple wire threading grooves are opened through the left and right ends of the protective wire box, and multiple cables in the open air are partially placed in the protective wire box and separated by multiple partitions. V-shaped elastic card plates are provided on the partition plates, so that the cables are squeezed and rebounded when embedded, and are limited and fixed. Although the device can prevent cables from being corroded by sunlight and rain, the length of the entire device cannot be adjusted, and protective wire boxes of different lengths need to be customized according to actual needs, which is more troublesome, and the device cannot protect cables at bends. The V-shaped elastic card plates are not easy to remove after the cables are installed, which makes it more troublesome to inspect or disassemble the cables. Utility Model Content
