Highway bridge hollow steel pier high-temperature protection system and bridge protection system thereof
The invention relates to a highway bridge hollow steel pier high-temperature protection system and a bridge protection system thereof. The high-temperature protection system comprises a liquid medium, a water cooling head, a fire sensing device, a heat dissipation system and a processing system. The liquid medium is used for absorbing heat and gasifying to transfer heat at the bottom of the hollow steel pier upwards; the water cooling head is used for absorbing heat above the hollow steel pier; the fire sensing device comprises a smoke sensor and a temperature sensor; the heat dissipation system comprises a pump machine arranged on the bridge support, a first water inlet pipeline, a second water inlet pipeline, a heat dissipation pipeline and a water outlet pipeline, a cooling channel is formed in the water cooling head, and the components form a water flow loop; and the processing system is used for controlling the opening and closing of the pump according to the information obtained through judgment. Heat at the bottom of the hollow steel pier is upwards transferred to the water cooling head through gasification of the liquid medium, then heat of the water cooling head is taken away through water circulation, heat dissipation of the pier is achieved, and damage to the pier is reduced.
本发明涉及一种公路桥梁空心钢桥墩高温保护系统及其桥梁保护系统，高温保护系统包括：液体介质、水冷头、火灾感应装置、散热系统和处理系统。液体介质用于吸热气化将空心钢桥墩底部的热量向上传递；水冷头用于吸收空心钢桥墩上方的热量；火灾感应装置包括烟雾传感器和温度传感器；散热系统包括设置在桥梁支座上的泵机、第一进水管道、第二进水管道、散热管道和出水管道，水冷头内部开设有冷却通道，上述部件形成一条水流回路；处理系统用于根据判断获取的信息来控制泵机开启和关闭。本发明利用液体介质气化将空心钢桥墩底部的热量向上传递至水冷头，再通过水循环将水冷头热量带走，实现对桥墩的散热，降低对桥墩的损坏。
