[0022] ​​The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] like Figures 1-4 As shown in the figure, an adjustable water-saving gate for a water conservancy project according to this embodiment includes a frame 1; a gate plate 2, the inner side of the frame 1 is provided with a sliding groove 3, the gate plate 2 is slidably disposed inside the sliding groove 3, a distance sensor 9 is provided on the inner wall of the bottom surface of the frame 1, the distance sensor 9 is used to detect the distance between the gate plate 2 and the bottom surface of the frame 1, thereby controlling the water discharge of the gate; a flow guiding mechanism, the flow guiding mechanism includes a flow guiding plate 7 and a flow guiding channel 8, the flow guiding plate 7 is disposed at the lower part of the water outlet side of the frame 1, and several flow guiding channels 8 are disposed on the flow guiding plate 7, the flow guiding plate 7 is an arc-shaped plate, the arc-shaped plate bends upward, when water is discharged, the upwardly bent flow guiding plate 7 and flow guiding channel 8 guide the strong water flow upward, causing the water flow to surge upward, thereby avoiding the water flow directly impacting the foundation of the gate and strengthening the protection of the gate.

[0025] A threaded rod 4 is installed inside the gate plate 2. The upper part of the threaded rod 4 passes through the top of the frame 1 and is connected to the output end of the motor 5. The motor 5 is set above the frame 1 through the support rod 6. The motor 5 drives the threaded rod 4 to rotate, thereby controlling the raising and lowering of the gate plate 2 to complete the gate's functions of releasing and storing water.
