[0002] Sluice gates are needed to intercept river channels for water storage or drainage. Sluice gates can be divided into flap dams, hydraulic dams, air shield dams and other dam bodies. Air shield dams are a new type of water retaining structure that combines the advantages of rubber dams and steel gates. They can be used in different occasions and are mainly composed of shield plates, inflatable airbags and control systems.

[0003] For example, a new type of air shield dam disclosed in the Chinese invention patent No. 201610334714.5 has a side sealing device between the gate and the side wall. The side sealing device is a sealing airbag A arranged on the side of the gate. At least one protrusion A is arranged on the side wall, and the width of the protrusion is smaller than the width of the sealing airbag A. The top surface of the sealing airbag A is provided with a groove A adapted to the protrusion. The protrusions A are arranged radially through a center of a circle. The side sealing device is a sealing airbag B arranged on the side wall; a protrusion B is provided on the side of the gate that contacts the sealing airbag B, and the width of the protrusion B is smaller than the width of the sealing airbag B.

[0004] Although this type of air shield dam has good side sealing effect and long service life, the height of the shield plate cannot be adjusted according to the terrain during use to ensure smooth passage of water or cars. At the same time, the airbag cannot be easily inspected and repaired, making it inconvenient to use and inefficient. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1~2 As shown, an air shield dam of the present invention is composed of a shield plate 1 and an anchor 2. The shield plate 1 is connected to a dam foundation 3 through the anchor 2. A first installation cavity 16 and a second installation cavity 17 are opened at the lower right end of the dam foundation 3. A pump 15 is installed in the first installation cavity 16. A wear-resistant protective plate 4 is installed on the outer side of the shield plate 1. Figure 3 As shown, the wear-resistant protective plate 4 is provided with a first airbag 5. Figure 4 As shown, the wear-resistant protective plate 4 is connected to the iron plate 6 on all sides, a through hole 7 is opened in the middle of the iron plate 6, the through hole 7 is connected to the shield plate 1 through a limit block 8, the upper and middle inner side of the shield plate 1 is connected to the first air pipe 10 through a guide groove 9, the first air pipe 10 is connected to the second air bag 12 through an inflatable piece 11, the second air bag 12 is connected to the spring air pipe 13 through the inflatable piece 11, the spring air pipe 13 is connected to the pump 15 through the second air pipe 14, the upper part of the shield plate 1 is connected to the anchor 2 through a suppression belt 18, and the anchor 2 is connected to the second mounting cavity 17. The wear-resistant protective plate 4 can extend the service life of the shield plate 1 and reduce the number of maintenance times; on the one hand, the limit block 8 can prevent the wear-resistant protective plate 4 from being separated from the shield plate 1 after the gas is filled into the first airbag 5. At the same time, when repairing the first airbag 5, it is only necessary to remove the limit block 8 and move the wear-resistant protective plate 4, which is convenient for loading and unloading and efficient; the two inflatable parts 11 of the second airbag 12 are exposed to the air. When repairing the inflatable parts 11, the inflatable parts 11 can be directly repaired without digging up the dam foundation 3 and then repairing it, which saves time, improves efficiency and is convenient to use.

[0022] like Figure 5 As shown, the inflatable member 11 includes a fixed block 19 and an air disc 20. A cavity 23 is opened in the middle of the fixed block 19. The lower end of the fixed block 19 is connected to a sealing ring 21. The sealing ring 21 is connected to the air disc 20 by screws 22. Figure 6As shown, a plurality of air outlet holes 24 are provided at the bottom of the air disc 20. The cavity 23 is connected to the air pipe. When the gas is discharged from between the inner airbag 122 and the outer airbag 121, if a single air outlet is working, the inner airbag 122 will block the air outlet due to the pressure difference. The plurality of air outlet holes 24 on the air disc 20 can prevent the inner airbag 122 from blocking the air outlet holes 24, thereby avoiding damage to the inner airbag 122. When the gas is filled between the inner airbag 122 and the outer airbag 121, the plurality of air outlet holes 24 can reduce the noise of the gas flow, and the use is convenient.

[0023] like Figure 1 As shown, the second airbag 12 is a double-layer structure, the outer airbag 121 is connected to the first air tube 10 through the inflatable member 11, and the inner airbag 122 is connected to the second air tube 14 through the inflatable member 11. When the shield plate 1 needs to be lowered, the gas between the inner airbag 122 and the outer airbag 121 can be filled into the first airbag 5 as needed, so as to better allow water flow or cars to pass, prevent the wear-resistant protective plate 4 from damaging the shield plate 1, and also play a buffering role; when the shield plate 1 is raised, the gas in the first airbag 5 can be pressed into the space between the inner airbag 122 and the outer airbag 121 by the pressure of the water body, and then the inner airbag 122 is inflated by the pump 15. The gas in the first airbag 5 can reduce the working time of the pump 15 and extend the service life of the pump 15, which is convenient and efficient to use.

[0024] like Figure 1 As shown, the curvature of the wear-resistant protective plate 4 is equal to that of the shield plate 1. According to the terrain requirements, it can meet the passage of water in the river or cars in the underground garage, avoiding slow water flow or car collision and congestion due to the incompatibility of the wear-resistant protective plate 4 with the terrain, and is convenient and efficient to use.

[0025] like Figure 1 As shown, a support member 25 is installed on the inner side of the top of the shield plate 1, and the support member 25 includes a support frame 26, and the support frame 26 is connected to a rubber pad 28 through a spring 27. When the air shield dam needs to be lowered, the spring 27 can play a buffering role, thereby avoiding damage to the structure of the shield plate 1 due to the shield plate 1 descending too fast, and the rubber pad 28 can prevent the spring 27 from being damaged, which is convenient to use.

[0026] Although specific embodiments of the present invention are described above, those skilled in the art should understand that these are merely examples and that various changes or modifications may be made to the embodiments without departing from the principles and essence of the present invention. The scope of protection of the present invention is limited only by the appended claims.
