Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable protection technology, specifically a photovoltaic cable protection and separation device. Background Technology

[0002] A photovoltaic (PV) power generation system, or simply PV, refers to a power generation system that directly converts solar radiation energy into electrical energy using the photovoltaic effect of photovoltaic cells. PV power generation systems are divided into stand-alone PV systems and grid-connected PV systems. A PV power generation system consists of equipment such as solar cell arrays, battery banks, charge / discharge controllers, inverters, AC distribution cabinets, and solar tracking control systems, all connected by cables.

[0003] According to the patent application CN217135445 U, "This utility model discloses a cable protection and separation device for photovoltaics, relating to the field of photovoltaic cable protection technology. It includes a cable and a protective box. Multiple cables are embedded and extended inside the protective box, and an upper protective cover is installed on the top of the protective box for sealing. Multiple connecting ears are connected to the front and rear ends of the protective box, and multiple drainage grooves are evenly distributed at the bottom of the protective box. Multiple wire-passing grooves are provided through the left and right ends of the protective box. This utility model provides that multiple exposed cables are partially inserted into the protective box and separated by multiple partitions to prevent tangling. V-shaped elastic plates are provided on the partitions to squeeze and rebound the cables during insertion, thus limiting and fixing them. The inserted cables are brought out from the wire-passing grooves at the left and right ends. Then, the upper protective cover is embedded and fixed to the protective box. The exposed cables are neatly installed in the protective box to prevent damage from external forces."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model improves the sealing performance by inserting multiple insert blocks on the protective box into multiple cable slots, allowing the lower rubber ring to enter the upper rubber ring and contact and compress the cable. However, in actual use, when there are many cables, multiple separation devices are needed to separate the cables. But when the number of cables is less than the number of cable slots, the sealing performance of the device cannot be guaranteed, which has certain limitations. Therefore, it is necessary to improve the photovoltaic cable protection and separation device to solve the above problems. Utility Model Content
