Description

Technical Field

[0001] This utility model relates to the field of grounding device technology, and in particular to a grounding device for lightning protection communication towers. Background Technology

[0002] In modern communication network architecture, communication towers, as key hubs for signal transmission and reception, are widely distributed in various terrains such as cities, mountains, and open fields, providing people with voice calls and data transmission communication services. However, the towering structure of communication towers makes them extremely vulnerable to lightning strikes. Lightning protection has become a core requirement for the safe operation of communication towers. As a key component of the lightning protection system, the performance of the grounding device directly determines the lightning protection effect of the communication tower. The development history of communication tower lightning protection grounding devices is closely linked to the evolution of communication technology and breakthroughs in lightning protection theory. Early communication technology was mainly based on analog signals, and the equipment was relatively simple with lower requirements for lightning protection. Grounding devices often used simple metal conductors, such as galvanized round steel or flat steel, directly buried in the soil, which could only achieve basic lightning discharge functions. At this time, the industry began to explore improvement solutions. In terms of resistance reduction technology, chemical resistance-reducing agents were introduced to wrap the grounding electrode. By reducing the resistivity of the soil around the grounding electrode, the efficiency of lightning discharge was improved. However, long-term practice revealed that the resistance-reducing agent suffered from agent loss and soil compaction, resulting in a gradual decline in the resistance reduction effect and difficulty in maintaining a stable low grounding resistance.

[0003] Currently, grounding devices on the market mainly consist of grounding electrodes and grounding trunk and branch lines. The connection between the grounding electrodes and lines in current communication tower grounding devices mostly uses traditional bolting and welding methods. In the early stages of communication technology development, communication equipment was relatively simple, and the requirements for lightning protection grounding were low. This type of connection could meet basic needs. However, with the rapid development of communication technology and the evolution of communication equipment towards high precision and high integration, stringent requirements have been placed on the stability and reliability of lightning protection grounding. The drawbacks of traditional connection methods have become increasingly apparent. When installing grounding devices for large communication towers, if multiple sets of grounding electrodes are involved in the connection with lines, the bolting work alone can take several hours, seriously affecting the construction progress.
