Hydraulic lifting weir
The invention discloses a hydraulic lifting weir in the field of water conservancy facilities. The hydraulic lifting weir comprises lock walls arranged on two sides of a river channel, wherein a gate body is arranged between the lock walls; the gate body is rotatably arranged at the bottom of the river channel through a rotating shaft; a vertical section of the gate body comprises a water retaining segment and at least one radial closing segment, wherein the radial closing segment is connected between the water retaining segment and the rotating shaft; a gate chamber provided with an opening in the upper part is arranged at the bottom of the river channel; two ends of the gate chamber extend to the lock walls; the gate body is arranged at the opening; the gate body and the opening are in sealed connection through sealing elements; the gate body and the lock walls are in sealed connection through sealing elements; a water inlet-and-outlet communicated with a space at the lower side of the gate body is arranged in the gate chamber; limiting mechanisms are arranged between the gate body and the gate chamber or between the gate body and the lock walls. According to the hydraulic lifting weir, water is filled in the gate chamber through the water inlet-and-outlet, so that the gate body rises and water storage is achieved; through the water inlet-and-outlet, the water in the gate chamber is discharged, and the gate body falls, so that water drainage is achieved; the hydraulic lifting weir has the advantages of no arrangements of a hoist and a central pier, convenience for control and low cost, and can be used for controlling all kinds of river water levels.
