Description

Technical Field

[0001] The utility model relates to the field of underground cable installation equipment, and more specifically, to an underground cable protection device for urban lighting. Background Art

[0002] In a dark environment, urban lighting plays a vital role. Lighting can illuminate relatively dark places, making it convenient for people to travel and live at night. Urban lighting is generally achieved through lighting equipment such as street lamps. The cables of street lamps are generally installed underground so as not to affect the upper space of the city. When installing cables underground, protective devices are generally required to protect the cables to reduce damage to the cables. Existing cable protection devices are generally fixed frame structures. The frame structure covers the outside of the cable. When the soil moves, the frame structure is squeezed to deform. When the frame structure deforms, it also squeezes the outer skin of the cable, which can easily cause damage to the cable. At the same time, the existing protection device lacks an adjustment structure, and the protection device cannot be adjusted according to the diameter of the cable, thereby reducing the adaptability of the protection device and making it inconvenient to fix the protection device to the cable.
