When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] The terms used in the embodiments of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The singular forms of "a", "the", and "said" used in the embodiments of the present utility model and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0032] Please refer to Figures 1-5 , and a description will now be given of an ecological wetland water inlet control device provided by an embodiment of the present utility model.

[0033] In one embodiment, an ecological wetland water inlet control device according to an embodiment of the present utility model includes: a floating body box 4, a pipeline 3, and a trash screen 11. An inlet 8 is provided on the side wall of the floating body box 4, and a support plate 9 and a weir plate 5 are provided inside it; the bottom elevation of the inlet 8 is lower than the river water level, one end of the support plate 9 is fixed to the lower side of the inlet 8, and the weir plate 5 is fixed to the support plate 9; one end of the pipeline 3 is communicated with the bottom outlet of the floating body box 4, and the other end is used to penetrate a retaining wall 2 between the river and the wetland system 1; the trash screen 11 is disposed closely against the weir plate 5; the lower side of the trash screen 11 is fixed to the weir plate 5 or the support plate 9, and the upper side is fixed to the top of the floating body box 4.

[0034] In this embodiment, the trash screen 11 can be disposed on the water-facing side of the weir plate 5 or on the backwater side of the weir plate 5, as long as it is disposed closely against the weir plate 5. In this way, the trash screen 11 can intercept large debris or garbage in the river water flowing through the weir plate 5, prevent large debris or garbage in the river water from entering the floating body box 4, avoid blockage of the floating body box 4 and the pipeline 3 caused by entering debris or garbage, and keep the water flow of the wetland water inlet clear.

[0035] Furthermore, an ecological wetland water inlet control device according to this embodiment further includes a sand interception device 20, and the filter holes of the sand interception device 20 are smaller than the mesh holes of the trash screen 11; the sand interception device 20 is disposed at the outlet of the pipeline 3. In this way, the water inlet control device of this embodiment first intercepts large debris or garbage in the river water through the trash screen 11, and then filters the river water about to enter the wetland system 1 again through the sand interception device 20 to intercept debris such as smaller particles of sand and gravel in the river water, making the river water entering the wetland system 1 clearer.

[0036] Furthermore, the sediment interception device 20 of this embodiment includes a baffle 206 and a filter screen. A clamping groove 205 is provided on the baffle 206, and the filter screen is clamped in the clamping groove 205. The outlet of the pipeline 3 is located above the filter screen. A water outlet 204 is provided on the lower side of the baffle 206. The water outlet 204 is located below the filter screen and is higher than the bottom surface of the sediment interception device 20, that is, the bottom of the orifice of the water outlet 204 is slightly higher than the bottom layer of the sediment interception device 20, which is convenient for storing some unfiltered sediment at the bottom of the sediment interception device 20. The filter screen is clamped with the baffle 206 through the clamping groove 205, which is convenient for the installation, removal and cleaning of the filter screen. In addition, the baffle 206 can prevent the river water from flowing directly into the wetland system 1 without passing through the filter screen.

[0037] Furthermore, the filter screen of this embodiment includes a first-layer filter screen 201, a second-layer filter screen 202 and a third-layer filter screen 203 with gradually decreasing filter holes from top to bottom. The water outlet 204 is located below the third-layer filter screen 203. That is, the first-layer filter screen 201 can filter coarse sand, the second-layer filter screen 202 filters medium sand, and the third-layer filter screen 203 can filter fine sand, and the remaining extra-fine sand sinks to the bottom of the sediment interception device 20. Most of the sediment can be intercepted after the sediment-containing water body passes through the three-layer filter screen, making the water flow clear. After passing through multiple-stage filtration, the water flow flows into the wetland system 1 through the water outlet 204 at the bottom layer of the sediment interception device 20.

[0038] Furthermore, the weir plate 5 of this embodiment includes a fixed plate 7 and a moving plate 6. The fixed plate 7 is fixed on the support plate 9, and the moving plate 6 is slidably connected to the inner side wall of the floating body box 4. The moving plate 6 is located directly above the fixed plate 7, and the lower side of the moving plate 6 can be closed with the upper side of the fixed plate 6. The top elevation of the fixed plate 7 is lower than the river water level, and the size of the opening between the moving plate 6 and the fixed plate 7 is the maximum water flow rate that can enter the wetland system 1. By controlling the lifting of the moving plate 6, the maximum water flow rate entering the wetland system 1 can be controlled.

[0039] Furthermore, a first inclined surface that slopes downward is provided at the top of the backwater side of the fixed plate 7 of this embodiment, and a second inclined surface that slopes downward is provided at the bottom of the water-facing side of the moving plate 6. When the moving plate 6 moves to the top of the fixed plate 7, the first inclined surface and the second inclined surface can be completely attached to prevent the water flow from entering the inside of the floating body box 4.

[0040] Furthermore, an ecological wetland water inlet control device of this embodiment further includes a flow velocity meter 10 for measuring the flow velocity of the river inflow. The flow velocity meter 10 is fixed on the fixed plate 7. The lifting of the moving plate 6 can be controlled according to the flow velocity measured by the flow velocity meter 10, so as to control the water flow rate entering the wetland system 1.

[0041] Further, an ecological wetland water inlet control device according to this embodiment further includes a water isolation bin 15 arranged on the upper part of the floating body box 4, and the interior of the water isolation bin 15 is coated with a waterproof material. A driving unit 16 is arranged inside the water isolation bin 15. The driving unit 16 includes a driving motor 17 and a wire winding roller 18. A guide rope 14 connecting the moving plate 6 is wound around the wire winding roller 18, and the driving motor 17 is used to drive the wire winding roller 18 to rotate. By driving the wire winding roller 18 to rotate forward or backward by the driving motor 17, the retraction and release of the guide rope 14 are realized, and further the lifting or lowering of the moving plate 6 is realized to control the water flow rate entering the wetland system 1.

[0042] Further, an ecological wetland water inlet control device according to this embodiment further includes a controller 12. The controller 12 controls the rotation of the driving motor 17 according to the flow rate data received by the flow meter 10, and the controller 12, the flow meter 10 and the driving motor 17 are electrically connected. There is a display screen on the controller 12, which can display the water flow rate. The controller 12 can be set manually. When the water flow rate is large and the flow rate measured by the flow meter 10 is higher than a certain critical flow rate value set manually, the controller 12 can drive the guide rope 14 to move the moving plate 6 downward by controlling the driving motor 17 to rotate forward, blocking the water from entering the floating body box 4. When the water flow rate slows down and the flow rate measured by the flow meter 10 is lower than the flow rate value set manually, the controller 12 can drive the guide rope 14 to move the moving plate 6 upward by controlling the driving motor 17 to rotate in reverse, allowing more water to enter the floating body box 4. In this way, by setting the flow meter 10, the driving unit 16 and the controller 12, the automatic control of the water inflow rate in the floating body box 4 can be realized.

[0043] Further, an ecological wetland water inlet control device according to this embodiment further includes a solar panel 13, and the solar panel 13 is used to supply power to the controller 12 and the driving motor 17. The solar panel 13 is fixed on the top of the floating body box 4. By setting the solar panel 13, natural power supply can be realized, without the need for an external power supply, which is more energy-saving and more convenient for installation.
