Self-anchored water gate for water conservancy

The utility model relates to the technical field of water conservancy facilities, and discloses a self-anchored sluice for water conservancy, which comprises a sluice mounting base, a first sluice limiting groove is formed in the middle end of the left side of the inner wall of the sluice mounting base, and a second sluice limiting groove is formed in the middle end of the right side of the inner wall of the sluice mounting base. A mounting frame is fixedly mounted at the middle end of the top of the water gate mounting base, and a first automatic precise drainage mechanism and a second automatic precise drainage mechanism are arranged, so that when small-scale drainage is needed, the first automatic precise drainage mechanism and the second automatic precise drainage mechanism can drain water through opening a switch of a high-water-level drainage groove or a low-water-level drainage groove; water is drained through the high-water-level drainage groove or the low-water-level drainage groove, the whole high-s
