Hydraulically-driven self-floating flow guide pier
The invention discloses a hydraulically-driven self-floating type flow guide pier which comprises a fixed flow guide pier, a supporting hinge and a floating box. The fixed flow guide pier is arranged at an estuary where branches converge into a main stream, and the whole fixed flow guide pier is of an inverted-Y-shaped structure in an overlook mode; a plurality of buoyancy tanks with certain intervals are hinged to the water facing side faces of the two wings of the fixed flow guide pier through supporting hinges. And the buoyancy tank can rotate around the trunnion and float and sink along with the change of the water level of the branch. When the water level of the branch in the dry season is low, the buoyancy tank is horizontally arranged on the bottom face of the fixed flow guide pier or is in a semi-floating state and does not participate in flow guide basically, and the fixed flow guide pier is mainly used for flow guide so as to reduce the impact of branch catchment on ships in the main flow channel. When the branch water level is high or even exceeds the top face of the fixed flow guide pier in the wet season, the floating box is in a vertical state under the action of water flow buoyancy, and therefore impact of branch catchment on a main flow channel ship is effectively reduced; and when the branch water level is lowered, the buoyancy tank can return to the bottom surface position of the fixed flow guide pier.
本发明公开了一种水力驱动自浮式导流墩，包括固定导流墩、支铰和浮箱；所述固定导流墩设置在支流汇入干流的河口，其整体俯视呈倒“Y”形结构；所述固定导流墩的两翼迎水侧面上通过支铰铰接有若干个具有一定间距的所述浮箱；所述浮箱能够绕支铰旋转并随着支流水位的变化而浮沉。在枯水期支流水位较低时，所述浮箱平卧于所述固定导流墩的底面或处于半浮状态，基本不参与导流，主要由固定导流墩导流以减小支流汇水对干流航道船只的冲击；在丰水期支流水位较高甚至超过固定导流墩的顶面时，浮箱在水流浮力的作用下处于竖立状态，从而有效减小支流汇水对干流航道船只的冲击；当支流水位降低时，浮箱又会回到平卧于固定导流墩的底面位置。
