Description

螺杆启闭机液控应急操作设备
本申请要求享有2019年3月20日提交的中国专利申请201910212613.4的优先权和2019年3月20日提交的中国专利申请201920358670.9的优先权，它们的全部内容通过引用结合在本申请中。
技术领域
本发明涉及应急操作设备，尤其涉及一种螺杆启闭机液控应急操作设备。
发明背景
当前，在水利工程、水电工程以及航运工程中，螺杆启闭机的应用越来越广泛，工作闸门一般采用螺杆启闭机控制。而这些工作闸门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。如水库灌区河道堤坝闸门不能在一定的时间内关闭，可能会造成灌溉水资源的流失，如不能在一定的时间内开启，将直接影响农作物的及时灌溉。
但当螺杆启闭机电源供应出现故障，或是启闭机电动机出现故障时，启闭机将不能工作。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动机出现故障时还没有较好的应急措施，一般是靠人力手摇操作，效率较低。
