Broadcast television transmitting tower
The invention relates to a broadcast television launching tower which comprises a base and a lightning rod, the lightning rod comprises a plurality of conductive tubes, and the upper conductive tube and the lower conductive tube are welded and connected through full-length welding; a parallel damper is arranged between the upper conductive tube and the lower conductive tube, and a single-tube damping structure is arranged in each conductive tube. Through further optimization design of the structure of the single-tube lightning rod in the radio and television launching tower, the problem of fatigue damage of the welding position of the tubular joint of the single-tube lightning rod caused by the vortex-induced resonance phenomenon, the wind vibration response and the like of the lightning rod with a high terrain clearance in strong wind weather in the radio and television field is effectively solved; and the probability of accidents such as cracks and fractures is reduced, so that the service life of the lightning rod is prolonged.
本发明涉及一种广播电视发射塔，包括基座、避雷针，避雷针包括多根导电管，上下两根导电管采用满焊焊接连接；上下两根导电管之间还设置有并联式阻尼器，导电管内部也设置有单管式阻尼结构。通过对所述广播电视发射塔中的单管避雷针结构进一步优化设计，从而有效解决在广播电视领域中，对于高离地高度的避雷针在强风天气下的由于涡激共振现象、风振响应等原因导致单管避雷针的相贯节点的焊接处疲劳损伤问题，降低发生裂纹、断裂等事故的几率，从而延长避雷针的使用寿命。
