Abstract

[0002] Traditional channel management and object interception systems usually use a single or simple method to handle interception tasks. The most commonly used one is trash racks. Traditional trash racks are usually designed as fixed-size grids based on protection facilities and interception objects. This design lacks flexibility to a large extent and can only meet the single function of intercepting waste. It is difficult to make corresponding adjustments when the environment or needs change. For example, too dense trash racks may hinder the migration and life of fish and other aquatic organisms, threaten biodiversity, and destroy the aquatic ecological balance. It may also affect the self-purification ability of water bodies and deteriorate water quality. Failure to adjust and optimize traditional trash racks in a timely manner may cause their negative impact on the ecosystem to continue to expand, causing irreversible damage to the aquatic ecosystem.

DETAILED DESCRIPTION
[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0027] like Figure 1 As shown, this embodiment provides a channel adaptive interception device, and multiple channel adaptive interception devices are arranged along the water flow direction. The channel adaptive interception device includes an interception fence 1 and a channel empty box structure 10. The channel empty box structure 10 is fixedly arranged on both sides of the channel, and the interception fence 1 is arranged between the two channel empty box structures 10.
[0028] like Figure 2 As shown, the interception fence 1 includes a frame 2, which is arranged perpendicular to the riverbed. A plurality of guide grates 3 are arranged on one side of the frame 2. The guide grates 3 can be arranged on the upstream side or the downstream side of the frame 2. The plurality of guide grates 3 are arranged vertically and in parallel. The cross section of the guide grates 3 is an axisymmetric streamlined curved surface, which can reduce the flow loss and maintain the flow state stable. The guide grates 3 are rotatably connected to the frame 2 by hinges, as shown in FIG. Figure 6 As shown, the hinge includes an inner hinge 8 and an outer hinge 9. The inner hinge 8 is connected to the guide grid 3 by welding, and the outer hinge 9 is connected to the frame 2 by welding.
[0029] A driving device 5, a control rod 6 and a plurality of support seats 7 are arranged on the top of the frame 2. The control rod 6 is arranged perpendicular to the length direction of the guide grid 3 and is parallel to the frame 2. The control rod 6 is slidably arranged on the plurality of support seats 7. The driving device 5 can be fixed to the top of the channel empty box structure 10 by bolts. The driving device 5 adopts a horizontal hydraulic hoist. The driving device 5 is fixedly connected to one end of the control rod 6 to drive the control rod 6 to move axially, such as Figure 7 As shown, a plurality of connecting rods 17 are vertically arranged on the control rod 6, one end of the connecting rod 17 is fixed on the control rod 6, and the other end of the connecting rod 17 is rotatably connected to the guide grid 3, as shown in FIG. Figure 5As shown, a rotating shaft 4 is fixedly arranged on the top of the guide grid 3, and the connecting rod 17 is rotatably connected to the guide grid 3 via the rotating shaft 4. It can be understood that, in the process of driving the control rod 6 to move axially by the driving device 5, the connecting rod 17 will drive the guide grid 3 to rotate, so that the gap (flow width) between two adjacent guide grids 3 changes, thereby adaptively adjusting the interception fence 1.
[0030] The distance between two adjacent guide fence pieces 3 of the interception fence 1 gradually decreases from upstream to downstream, thereby ensuring interception efficiency and effectiveness.
[0031] like Figure 4 As shown, the frame 2 includes side beams 13, a bottom beam 15, a top beam 14 and a main beam 16. The bottom beam 15 and the top beam 14 are arranged in parallel. Two side beams 13 are provided. The two side beams 13 are respectively fixed at the two ends of the bottom beam 15 and the top beam 14. The main beam 16 is arranged in parallel between the bottom beam 15 and the top beam 14. The two ends of the main beam 16 are fixedly connected to the side beams 13. The two side beams 13 of the frame 2 are fixed to the side of the channel empty box structure 10 by expansion bolts. The side beams 13, the bottom beam 15, the top beam 14 and the main beam 16 are all welded and formed by standard steel. The frame 2 is the main force-bearing structure of the interception fence 1.
[0032] like Figure 3 As shown, the channel empty box structure 10 includes a concrete empty box 11, and the concrete empty box 11 is provided with openings on both sides along the water flow direction, and fixed grilles 12 are provided on the openings. The two sides of the concrete empty box 11 along the water flow direction are arranged obliquely, so that the distance between the two sides gradually decreases from the channel edge to the channel center. The concrete empty box 11 is designed and cast according to the channel cross-sectional dimensions. The channel empty box structure 10 provides installation convenience for the frame 2 and the driving device 5 of the interception fence 1, and the flow requirement at the channel edge is met through the concrete empty box 11.
[0033] The channel adaptive interception device of this embodiment adopts an adjustable guide grid 3 to replace the traditional fixed-size grid, which can be flexibly adjusted according to the size and type of the interception object. For objects of different sizes and types, the system can achieve more accurate interception, which is conducive to reducing interference with fish and other aquatic organisms of different sizes, thereby protecting the ecosystem and biodiversity. In addition, pollutants of various sizes can be effectively intercepted, thereby reducing pollution to the water body.
[0034] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
