[0014] The following is combined with Figure 1 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, rather than to limit the scope of the present invention.

[0015] An air shield dam comprises a plurality of shield plates 1, wherein the plurality of shield plates 1 are arranged at equal intervals, and also comprises a plurality of blocking components, wherein the blocking components are arranged between two adjacent shield plates 1; the blocking components comprise a first airbag body 2 and a second airbag body 3, wherein the first airbag body 2 is fixedly connected to one of the shield plates 1, and the second airbag body 3 is fixedly connected to the adjacent shield plate 1; the first airbag body 2 and the second airbag body 3 press against each other in an inflated state to achieve the purpose of water blocking; the first airbag body 2 and the second airbag body 3 separate from each other in a deflated state to achieve the purpose of drainage, and the first airbag body 2 and the second airbag body 3 are provided with inflation holes 4, through which the first airbag body 2 and the second airbag body 3 are inflated and deflated.

[0016] The shield plate 1 is connected with an angle detector 5, a fixed cylinder 6 and a fixed hole 7; the angle detector 5 is used to detect the folding angle of the shield plate 1, and the telescopic end of the fixed cylinder 6 is connected with a correction square steel 8, which can be inserted into the fixing hole 7 of the adjacent shield plate 1 under the drive of the fixed cylinder 6 to realize the series connection between the shield plates 1.
