DETAILED DESCRIPTION

[0021] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0022] like Figures 1-4 As shown, in this embodiment, the channel water-saving gate device based on buoyancy self-adjustment includes a gate 2 disposed in a gate slot 1, and a buoyancy linkage structure that cooperates with the gate 2. The gate has a guide wheel on its side. The buoyancy linkage structure includes a fixed rod 3 parallel to the backwater side of the gate 2. Several levers 4 are rotatably connected to the fixed rod 3 along its length. Each lever 4 has a first connecting end near the gate 2 and a second connecting end away from the gate 2. A connecting handle 5 is provided at the top of the gate. The first connecting handle 5 of the lever 4... The second connecting end is connected to the first limiting block 6 after passing through the connecting handle 5. The second connecting end is connected to the first float 8 through the connecting rod 7, so that the first float 8 can drive the gate 2 to rise and fall along the gate slot 1 as the water level on the back side of the gate rises and falls. The upper part of the water-facing surface of the gate 2 is fixedly connected to the first limiting plate 9. The bottom of the first limiting plate 9 is connected to several second floats 10. When the gate 2 is completely closed, the second floats 10 are set at a height higher than the first floats 8, so that when the water level on the water-facing side of the gate rises to the second floats 8, the gate 2 can be opened to release water under the action of the second floats 8.

[0023] Working principle: When the water level on the backwater side of gate 2 is lower than the set irrigation water level, such as Figure 1 As shown, under the influence of gravity, the first float 8 opens the gate 2 via lever 4. As the water level rises on the back side, the first float 8 rises, causing the gate 2 to decrease its opening degree via lever 4 until the irrigation water level is reached, at which point the gate 2 closes. Figure 2 As shown, when the irrigation water level drops, the first float 8 descends, causing the lever 4 to lift the gate 5, thus releasing water from the upstream side of the gate to the downstream side. This process repeats, achieving accurate control of the irrigation water level and effectively preventing excessive water release and waste of water resources. Specifically, when the water level on the upstream side of the gate exceeds the upper limit, the second float 10 can be used to lift the gate 2 for flood discharge, reducing upstream water pressure, until the two floats reach equilibrium and the gate closes.

[0024] The water-saving gate device of this application can, on the one hand, automatically adjust the opening and closing angle of the gate through the first float ball 8 to better control the irrigation water level on the back side and avoid excessive water release; on the other hand, when the water level on the front side is too high, the second float ball 10 can be used to assist the gate in opening to release floodwater and reduce the upstream water storage pressure.

[0025] In one of the embodiments, the gate slot comprises a side slot and a bottom slot, a movable filter screen 11 is connected between the bottom of the gate and the bottom slot to vibrate with the water flow impact after the gate 2 is opened, and the bottom of the gate is provided with a sealing part matched with the bottom slot. In this way, the sediment deposition can be prevented, and the manpower for frequent cleaning can be saved, thereby reducing the maintenance frequency.

[0026] In one of the embodiments, the lower end of the movable filter screen 11 is positioned and fixed by a counterweight 12 arranged in the bottom slot, and the movable filter screen 11 can also be fixed in the bottom slot by a ground nail or the like.

[0027] In one of the embodiments, a second limiting plate 13 is fixed at the top of the gate slot, and an adjusting rod 14 is connected to the second limiting plate 13 to limit the lifting height of the gate. The adjusting rod 14 is threadedly connected with the second limiting plate. The top of the adjusting rod 14 is connected with an adjusting hand wheel, and the bottom of the adjusting rod is connected with a second limiting block. During the adjustment, the height of the adjusting rod is changed by operating the adjusting hand wheel, and then the lifting height of the gate is limited.

[0028] The above specific embodiments cannot be regarded as the limitation of the protection scope of the utility model, and any alternative improvement or change made by the person skilled in the art to the embodiments of the utility model falls within the protection scope of the utility model.

[0029] The parts not described in the utility model are the known technology of the person skilled in the art.
