Description

Technical Field

[0001] This utility model belongs to the field of air shield dam technology, and in particular relates to a localized air-shield dam. Background Technology

[0002] Air-shield dams are a type of low-head water-retaining structure commonly used in my country, such as... Figure 1 As shown, the air-supported dam mainly consists of a shield plate assembly 1, a main anchoring pre-embedded component 2, a limiting anchoring pre-embedded component 3, airbags 4, rubber fittings, and an inflation / deflation system. Each airbag 4 is equipped with a separate inflation / deflation pipeline, which connects the airbag 4 to the control system. Figure 2 As shown, a single-span air-supported dam has one or more shield plate groups 1, each shield plate group 1 having two or more shield plates 5. Adjacent shield plate groups 1 are connected by flexible rubber connecting sheets 6. The operation of the air-supported dam involves inflating the air bladder with air, causing the air bladder to inflate and push the shield plate group to rise, thus blocking water. By expelling the air from the air bladder, the air bladder returns to a flat state under the weight of the shield plates and the gravity of the water, and the shield plates collapse onto the dam foundation to allow water to pass through.

[0003] If a current air-supported dam is to be used for flood control and debris removal, the entire dam needs to be collapsed, making it impossible to control with a single shield plate group. If the flexible connecting rubber sheet used to connect the two shield plate groups is omitted, the raising and lowering of a single shield plate group can be achieved. However, sharp objects such as stones and branches can easily enter the bottom of the airbag, causing damage and leakage. If this happens, a water-blocking weir needs to be set up upstream to repair the airbag. The entire repair process is complex and involves high mechanical and labor costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a localized venting air shield dam that can be controlled by a single shield plate group.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes at least one set of shield plate groups, each set of shield plate groups includes at least two shield plates and is equipped with a main anchoring pre-embedded component, a limiting anchoring pre-embedded component, and an airbag. The shield plate groups are respectively provided with protective plates and Ω-shaped waterstops on both sides. The protective plates include an upper connecting plate and a lower connecting plate. Multiple arc-shaped plates are provided between the upper connecting plate and the lower connecting plate. The upper connecting plate is connected to the shield plate group, and the lower connecting plate is connected to the air-supported dam foundation. The upper connecting plate and the arc-shaped plates, adjacent arc-shaped plates, and the lower connecting plate and the arc-shaped plates are respectively connected by rotating connectors. The upper end of the Ω-shaped waterstop is fixed to the shield plate group by a pressure plate, and the lower end of the Ω-shaped waterstop is fixed to the shield plate group by the upper connecting plate.

[0006] The partial spillway air-supported dam provided by this utility model features Ω-shaped waterstops on both sides of the shield plate assembly. Compared to the original method of connecting adjacent shield plate assemblies with flexible rubber, the shield plate assemblies with Ω-shaped waterstops on both sides are independent, allowing for the raising and lowering of a single shield plate assembly. When the entire air-supported dam is raised, the Ω-shaped waterstops of adjacent shield plate assemblies are in close contact, effectively stopping water flow and ensuring the overall water-blocking effect of the air-supported dam. Protective plates, consisting of an upper connecting plate, a lower connecting plate, and an arc-shaped plate, are installed on both sides of the shield plate assembly. The upper connecting plate connects to the shield plate assembly, and the lower connecting plate connects to the dam foundation. The upper connecting plate is connected to the arc-shaped plate, adjacent arc-shaped plates are connected, and the lower connecting plate is connected to the arc-shaped plate via rotating connectors. The entire protective plate is fan-shaped, allowing it to be unfolded and closed, ensuring that the raising and lowering of the air-supported dam follows a predetermined trajectory. The protective plates on both sides of the shield plate assembly enclose the airbag located in the middle of the shield plate assembly. When a single shield plate assembly collapses, the protective plates on both sides can effectively protect the airbag and improve the stability of the air-supported dam operation. The localized spillway air-supported dam provided by this utility model can regulate the downstream flow rate, conduct localized flood discharge, and remove floating debris. The protective plates of the localized spillway air-supported dam are simple to form, easy to process and produce, convenient to install, and effectively protect the airbag.

[0015] The specific structure of the partial leakage air shield dam of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1As shown, the existing air-supported dam includes a shield plate assembly 1, a main anchoring pre-embedded component 2, a limiting anchoring pre-embedded component 3, and an airbag 4.

[0017] like Figure 2 As shown, a single-hole air shield dam has two sets of shield plate groups 1, each set of shield plate groups 1 has multiple shield plates 5, and adjacent shield plate groups 1 are connected by flexible connecting rubber sheets 6.

[0018] like Figure 3 , Figure 4 , Figure 5 As shown, the present invention provides a three-stage shield plate group 1 for a partial spillway air shield dam. Each shield plate group 1 includes multiple shield plates 5 and is equipped with a main anchoring pre-embedded component 2, a limiting anchoring pre-embedded component 3, and an airbag 4. Protective plates 7 and Ω-shaped waterstops 8 are respectively provided on both sides of the shield plate group 1.

[0019] like Figure 6 As shown, the guard plate 7 includes an upper connecting plate 9 and a lower connecting plate 10. Multiple arc-shaped plates 11 are arranged between the upper connecting plate 9 and the lower connecting plate 10. The upper connecting plate 9 and the arc-shaped plates 11, adjacent arc-shaped plates 11, and the lower connecting plate 10 and the arc-shaped plates 11 are connected by rotating connectors 12.

[0020] like Figure 7 As shown, the Ω-shaped waterstop 8 unfolds into a long strip with a protrusion in the middle.

[0021] like Figure 8 As shown, the upper end of the Ω-shaped waterstop 8 is fixed to the shield plate 5 by the pressure plate 13, and the lower end of the Ω-shaped waterstop 8 is fixed to the shield plate 5 by the upper connecting plate 9. The pressure plate 13, the Ω-shaped waterstop 8, the shield plate 5, and the upper connecting plate 9 are connected by bolts 14.

[0022] The partial spillway air-shield dam provided by this utility model features Ω-shaped waterstops 8 on both sides of the shield plate assembly 1. Compared to the original method of connecting adjacent shield plate assemblies with flexible rubber, the shield plate assemblies 1 with Ω-shaped waterstops 8 on both sides are independent of each other, allowing for the raising and lowering of a single shield plate assembly 1. When the air-shield dam is raised as a whole, the Ω-shaped waterstops 8 of adjacent shield plate assemblies 1 are in close contact, effectively stopping water flow and ensuring the overall water-blocking effect of the air-shield dam. Protective plates 7, consisting of an upper connecting plate 9, a lower connecting plate 10, and an arc-shaped plate 11, are respectively installed on both sides of the shield plate assembly 1. The upper connecting plate 9 is connected to the shield plate assembly 1, and the lower connecting plate 10 is connected to the dam foundation. The upper connecting plate 9 and the arc-shaped plate 11, adjacent arc-shaped plates 11, and the lower connecting plate 10 and the arc-shaped plate 11 are connected by rotating connectors 12. The entire protective plate 7 is fan-shaped and can be unfolded and closed, ensuring that the air shield dam rises and falls exactly according to the set trajectory. The protective plates 7 on both sides of the shield plate assembly 1 surround the airbag 4 located in the middle of the shield plate assembly 1. When a single shield plate assembly collapses, the protective plates 7 on both sides can effectively protect the airbag 4 and improve the stability of the air shield dam operation.

[0023] The partial venting air shield dam provided by this utility model is not limited to the above-described structure. Any modifications, equivalent substitutions, and improvements made based on this utility model shall be included within the protection scope of this utility model.
