The hinge support 8 is fixed on the riverbed of the river channel, the gate 7 is rotated to control the opening angle of the gate through the bottom shaft 6, and the independent autonomy of the regulation of the water level of the river channel is realized by adjusting the water retaining height. The opening angle of the gate can meet the needs of any water level, and solve the contradiction between water storage and flood discharge in the urban river; and the top of the gate can form a landscape waterfall, which is highly ornamental and has a significant ecological landscape effect, which is integrated with urban construction; at the same time The aeration of the torrent at the top of the gate can realize aeration and dissolved oxygen, which is also very valuable for urban river water treatment. Preferably, in order to prevent the gate top from passing water to generate negative pressure, thereby causing the gate to vibrate, a plurality of water breakers are also distributed on the top of the gate 7 at regular intervals.

As a preferred embodiment, as shown in FIGS. 3-4 , both ends of the bottom shaft 6 pass through the gate walls 9 on both sides of the sluice chamber and enter the sluice electrical room 10 . The drive device that drives the bottom shaft to rotate. Optionally, the driving device is a motor, which drives the bottom shaft 6 to rotate through gear transmission; or the driving device is a hydraulic cylinder 11, which drives the bottom shaft 6 to rotate through a connecting rod transmission. When the driving device is the hydraulic oil cylinder 11, the rotation of the bottom shaft 6 is driven by the connecting rod transmission. The other end of the crank arm 12 is connected with the hydraulic cylinder 11 , and the hydraulic cylinder 11 drives the crank arm 12 to swing, thereby driving the bottom shaft 6 to rotate, and finally making the gate 7 form a fan shape around the bottom shaft 6 Swing to realize the control of the gate opening angle of the steel dam gate.
