Hydraulic rotary steel dam gate with multi-angle adjusting mechanism
The invention belongs to the technical field of steel dam gates, and particularly relates to a hydraulic rotating steel dam gate with a multi-angle adjusting mechanism, which comprises a base, a gate, a rotating adjusting mechanism and a supporting mechanism, and has the beneficial effects that a driving motor and a rotating screw rod are arranged, so that the gate can be subjected to up-and-down opening and closing adjustment and left-and-right rotating opening and closing adjustment; the adjusting modes of the gate are increased, multi-angle adjustment of the gate is achieved, meanwhile, the inner gate is installed in the gate, upstream water can be rapidly discharged by opening the inner gate during opening and closing operation, and when the upstream water level and the downstream water level are flush or the minimum water head difference of bottom shaft rotation design is met, the inner gate is opened. And the upstream and downstream static head difference of the steel dam gate is eliminated or greatly reduced, so that the internal force of the bottom shaft of the steel dam gate caused by the water head is basically eliminated or greatly reduced, the bottom shaft only bears the dead weight of the gate leaf and the small water flow force effect, the hydraulic opening and closing force at the two ends of the bottom shaft is greatly reduced, and the requirements for the material and consumption of the bottom shaft of the steel dam are reduced.
本发明属于钢坝闸技术领域，具体是一种具有多角度调节机构的液压旋转钢坝闸，包括基座、闸门、旋转调节机构和支撑机构，本发明所具有的有益效果是设置有驱动电机和转动螺杆，能够对闸门进行上下开关调节和左右旋转开关调节，增加了闸门的调节方式，实现了闸门的多角度调节，同时在闸门内部安装设置有内闸门，能够在、启闭作业时，通过打开内闸门，使上游水快速下泄，当上下游水位持平或满足底轴旋转设计的最小水头差时，消除或大幅减小了钢坝闸上下游静水头差，进而基本消除或大幅减小因水头造成的钢坝闸底轴内力，使底轴仅承受门叶自重与较小的水流力作用，大大减小了底轴两端液压启闭力，降低了对钢坝底轴材料和用量的要求。
