Water conservancy project gate

The invention belongs to the technical field of water conservancy gates, and discloses a water conservancy gate which comprises a gate frame, a gate mechanism and a garbage salvaging device are arranged at the top of the gate frame, rectangular grooves allowing filter screen plates to be embedded are symmetrically formed in one side of the gate frame, and one side of each rectangular groove and one side of the gate frame are arranged on the same plane. A second motor drives a driving gear to drive a driven gear to rotate, so that the driven gear drives a connecting shaft to drive two groups of driving bevel gears to mesh with a driven bevel gear to drive two groups of threaded rods to rotate, and two groups of movable columns are conveniently driven to ascend and descend along a mounting groove, so that garbage floating on one side of a filter screen plate is salvaged; the salvage efficiency of floating garbage in river water is improved, the salvage labor amount of workers is reduced, the safety guarantee of
