Description

Underground outdoor cabinet structure

Technical Field

The utility model relates to the field of cabinets, and in particular to an underground outdoor cabinet structure.

Background Art

An outdoor cabinet is a cabinet that is directly under the influence of natural climate, made of metal or non-metal materials, and does not allow unauthorized operators to enter and operate. It provides an outdoor physical working environment and safety system for wireless communication sites or wired network site workstations. Cabinets suitable for installation in outdoor environments, such as roadsides, parks, rooftops, mountainous areas, and flat ground. Base station equipment, power equipment, batteries, temperature control equipment, transmission equipment, and other supporting equipment can be installed in the cabinet, or installation space and heat exchange capacity can be reserved for the above equipment. The cabinet can provide reliable mechanical and environmental protection for the normal operation of internal equipment.

Outdoor cabinets are widely used in urban and rural network construction and renovation because of their flexible combination, wide distribution, easy transportation, relocation, easy installation, short construction period, low operating costs, small footprint and no pollution.

With the acceleration of the process of urban and rural modernization, urban construction has entered the stage of urban beauty aimed at improving streetscapes. Traditional outdoor cabinets are scattered and disorderly occupying the prime ground in downtown areas, which is incompatible with the beautiful urban environment. The construction of urban planning, highways, and public facilities has higher and higher requirements for network sites. In developed countries such as Europe, the United States, and Japan, outdoor cabinets have been gradually buried underground in accordance with the concept of urban ecological design.
