Bulkhead gate and gate groove assembly
The invention relates to a bulkhead gate and gate groove assembly, and belongs to the technical field of plane gate installation in water conservancy and hydropower engineering. The installation mode of the elastic reverse wheel device is firstly optimized, the axial acting force applied to the bulkhead gate by the spring obliquely points to the downstream side of the bulkhead gate, the oblique acting force can be decomposed into the acting force Fx perpendicular to the water flow direction and the acting force Fy in the downstream direction, and the axial force of a door leaf main beam of the bulkhead gate can be increased through Fx; the shear resistance and the bending resistance of the main beam are improved, so that the aim of saving materials is fulfilled; and the Fy compresses the water sealing piece towards the downstream, so that the water stopping effect is achieved. The elastic reverse wheel device can also serve as a side guide wheel, the side guide wheel of a traditional bulkhead gate is omitted, and the guide mechanism is simplified. In addition, the gate groove upstream side wall and the gate groove downstream side wall are both arranged in an inclined mode relative to the water flow direction, smooth transition is achieved at the corners, the cavitation erosion phenomenon can be avoided, the head loss is reduced, and meanwhile gate vibration is reduced.
本发明涉及一种平板闸门与门槽组件，属于水利水电工程中的平面闸门安装技术领域。本发明首先优化了弹性反轮装置的安装方式，弹簧施加给平板闸门的轴向作用力倾斜指向平板闸门的下游侧，该倾斜作用力可分解为垂直于水流方向的作用力Fx及顺水流方向的作用力Fy，Fx可使得平板闸门的门页主梁轴力增大，增加了主梁的抗剪和抗弯能力，从而达到节省材料的目的；Fy则向下游压紧水封件，起到止水效果。弹性反轮装置可以兼做侧导向轮的作用，将传统平板闸门的侧导向轮取消，简化了导向机构。此外，门槽上游侧壁和门槽下游侧壁相对于水流方向均呈倾斜布置状，并在角部实现平滑过渡，有利于避免空蚀现象，减少水头损失，同时减少闸门震动。
