摘　　要：为提高抽水蓄能电站尾闸室事故闸门防水淹厂房事故的能力,对事故闸门动水关闭方式及其与机组进水阀的闭锁方式进行分析,指出现有的设计存在的不足,并提出优化解决方案。并对事故闸门门槽顶盖螺栓设计进行探讨,建议该螺栓采用预紧连接,以提高其抗疲劳的能力。In order to improve the ability of the emergency gate in the tailrace gate chamber of the pumped-storage power station to prevent flooding of the powerhouse accident,the dynamic water closing method of the emergency gate and the locking method between the unit inlet valve and gate were analyzed.The deficiencies of existing designs and propose optimal solutions were pointed out.The design of the bolts on the top cover of the gate groove of the emergency gate was discussed,and it was suggested that the bolts should be pre-tightened to improve the anti-fatigue ability.
