技术领域
本发明涉及液压启闭机控制领域，特别是涉及一种应用于水利工程、水电工程以及航运工程的液压启闭机的应急操作装置。
发明背景
当前，在水利工程、水电工程以及航运工程中，液压启闭机的应用越来越广泛。但水利工程、水电工程及航运工作的工作闸门一般都有开启及关闭时间上的要求，如果不能在一定的时间内将闸门开启或关闭，将会产生不同程度的损失，甚至会产生严重的后果。如水电工程工作闸门由于启闭机电源、电气控制系统或电机故障不能及时关闭将浪费大量发电水资源，不能在一定的时间内开启可能会影响水库的泄洪，有可能对大坝产生安全上的影响。而防洪水利工程闸门如不能及时关闭将直接影响城市区域的洪涝，如不能在规定时间内开启有可能影响城市的排洪。而当液压启闭机电源供应或电气控制系统出现故障，或是启闭机电动机出现故障时，启闭机将不能工作，不能在一定的时间内进行关闭或开启，将会产生不同程度的损失。而目前对于电源供应出现故障的应对措施是配置柴油发电机，但柴油发电机配置的功率不能小于启闭机的电动机功率，因而，体积较大，且要有专门的柴油发电机室及一系列的控制系统，投资成本高，经济性差。而目前对于启闭机电气控制系统或电动机出现故障时还没有较好的应急措施。

所述液压调控模块上还设有手动换向阀和压力表。
