摘　　要：为了解决高空作业安全隐患,提出一种将报警器探头分离的思路,将报警器探头分为两部分,一部分为固定部分,一部分为可移动部分。固定部分包括防爆接线盒及线盒内电磁铁、接线柱等;可移动部分为探头主体,可对其标定、调整等操作。两部分通过电磁铁吸合,在检定或维护保养报警器时,通过遥控器切断电磁铁吸力可方便将探头从高空取下。此外,就防爆接线盒的防爆类型、结构尺寸、结构强度及电磁铁选型等进行详细计算设计。This paper proposes a separable probe for combustible gas detection in order to decrease the risk of highaltitude operation.In this design,the probe is divided into two parts,i.e.one fixed part and one removable part.The fixed part includes an explosion-proof junction box and an electromagnet terminal in the box.The removable part is the main part of the probe,which can be removed for calibration and adjustment.The two parts are attached to one another by the electromagnet.When the probe needs verification or maintenance,the electromagnet is turned off by remote control,so that the removable part can be taken off.The explosion-proof type,structure size,structure strength of the explosion-proof junction box,and electromagnet selection are analyzed in detail.
