摘要
提出构建以泡沫陶瓷为主材料的煤矿井下自动风门,材料由泡沫陶瓷,不对称多孔金属材料,压力传感器,PLC软件控制装置构成,门体两侧装配压力传感器,门底部设有护门体窗,采用PLC软件控制,并在门体上装有门限传感器、光敏传感装置、防夹车装置、声光指示器等,实现灾前控制风流,灾后自动卸压并阻隔瓦斯爆炸火焰传播的功能。
Suggests to establish the automatic air door of underground coal mine using the ceramic foam as the main material. The materials consist of the ceramic foam, the asymmetric porous metal materials, the pressure sensor and the PLC software control device. The pressure sensors have been assembled to both sides of the air door. There are windows to be assembled at the bottom of the air door to proctect it using the PLC software to control it. Also assemble the threshold sensor, the photosensitive sense device, the device to prevent clipping vehicles and the acoustic-optic indicator to achieve the function of controlling the airflow before the disaster and the fuction of leaking pressure autimatically and isolating the spread of the flame of the gas explosion after the disaster.
