Description

Technical Field

[0001] This utility model relates to the field of power cable technology, and in particular to a rodent-proof device for cable holes. Background Technology

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. During the laying of power cables, rodent-proof devices for cable holes are often required to effectively protect the cables.

[0003] A search revealed a rodent-proof device for cable holes, disclosed in patent number CN219165532U. The device includes a cable conduit with an external wall-mounted base plate at its front end. An external wall-mounted cover, matching the base plate, is located on the front side of the external wall-mounted cover. A gear disk with several driven gears meshing within it is also present. A rotating blade is positioned behind each driven gear. Several fixing bolts are threaded through the external wall-mounted cover, connecting the driven gears to the rotating blades. An adjustment mechanism, including a drive gear housing, is located on one side of the external wall-mounted cover. However, this patent requires manual adjustment for rodent prevention, and its overly complex structure significantly reduces its practicality. Therefore, we propose a rodent-proof device for cable holes to address these issues. Utility Model Content
