摘　　要：目前船闸反弧门启闭位置控制主要依赖于开度检测装置和位移传感器,由于船闸反弧门在高水头下动水启闭频繁,当吊杆连接轴及轴套磨损后,会造成反弧门启闭位置误差逐渐增大,使得反弧门存在超关现象,进而对反弧门门体、止水、底坎埋件造成破坏。针对此问题,从提高启闭控制系统的精度方面对船闸反弧门运行状态检测方案进行研究。分析了反弧门位置控制系统存在的问题,采用在反弧门门体内部安装倾角传感器的方式对启闭位置角度信息进行检测,提高了启闭位置控制精度。2021年在葛洲坝三号船闸右充反弧门实施了运行状态检测装置的安装施工与测试,验证了反弧门运行状态在线检测系统的技术可行性以及检测水平的先进性。At present,the opening and closing position control of reversed tainter valve of ship lock mainly depends on the chain drive opening detection device and proximity switch.Since the reversed tainter valve of ship lock is frequently opened and closed under high water head,when the connecting shaft and the shaft sleeve of the boom are worn,the opening and closing position error of the reversed tainter valve will gradually increase,causing the over-closing phenomenon of the reversed tainter valve,and then causing damage to the valve body,water stop and bottom sill embedded parts of the reversed tainter valve.Aiming at this problem,this paper studies the operation state detection scheme of the reversed tainter valve of the ship lock by improving the accuracy of the opening and closing control system.The problems existing in the position control system of the reversed tainter valve are analyzed,and the angle information of the opening and closing position is detected by installing the inclination sensor inside the valve body of the reversed tainter valve,which improves the control accuracy of the opening and closing position.In 2021,the installation,construction and testing of the operating state detection device were implemented at the right-charge reversed tainter valve of Gezhouba No.3 ship lock,which verified the technical feasibility of the online detection system for the operating state of the reversed tainter valve and the advanced detection level.
