Ventilation cooling system for power transmission steel box girder section of sea-crossing bridge

Provided is a ventilation cooling system for a power transmission steel box girder section of a sea-crossing bridge. The system comprises a temperature monitoring system, a fresh cold air supply system and a dirty hot air exhaust system. The temperature monitoring system is composed of a temperature sensor, a data acquisition module and a data sending module, and the data acquisition module is internally provided with a temperature sensor data transmission line, and a terminal signal converter, ensuring that the sensor data is converted into a visual chart. Through intelligent temperature monitoring, internal cold air supply and hot air exhaust, the temperature of the cable in the large-span navigable hole bridge steel box girder section of the sea-crossing bridge can be controlled in real time, the power transmission effect of the cable is powerfully guaranteed, and the power transmission efficiency of the power transmission cable in the cable is improved. 一种用于跨海桥梁输电钢箱梁段的通风降温系统，该系统包括：温度监测系统、新鲜冷风供给系统和污浊热风排出系统
