The nylon cloth 5 is hung on the floating tube 3 through a connecting rope 4, a fixed pulley 301 is fixedly arranged at the lower end of the floating tube 3, a steel pendant 7 is fixedly arranged at one end of the connecting rope 4, and a mud surface line 8 is provided below the steel pendant 7. The other end of the connecting rope 4 bypasses the fixed pulley 301 and is fixedly connected to the balance steel tube 9, the upper part of the nylon cloth 5 is connected to the floating tube 3 through a pressing plate 302 and a first bolt 303, and the floating plate and the pressing plate 302 are arranged with equal length. The first bolts 303 are arranged at intervals of 250m-350m, and the lower part of the nylon cloth 5 is connected to the steel pendant 7 through the second bolt 501, and the steel pendants 7 are arranged disconnected. The steel pendants 7 are arranged at intervals of 2.5m-3.5m, and a rubber airbag 10 is arranged in the balance steel pipe 9, and a limit rod 6 is fixed on the contact rope 4. The balance steel pipes 9 are arranged disconnected, and the balance steel pipes 9 are arranged at intervals of 2.5m-3.5m. The steel pendants 7 correspond to the balance steel pipes 9 one by one and are arranged in sections. The weight of the steel pendants 7 is less than the weight of the balance steel pipes 9. The limit rod 6 is arranged on two adjacent contact ropes 4, that is, one limit rod 6 is arranged on every two adjacent contact ropes 4.

[0026] The inflatable and adjustable dredging anti-pollution curtain of the present invention comprises a floating tube 3, a connecting rope 4, a nylon cloth 5, a limit rod 6, a steel pendant 7, a balance steel tube 9, a rubber airbag 10, etc. The curtain is arranged outside the grabbing range of the grab bucket 2, the floating tube 3 floats on the water surface, the nylon cloth 5 is hung on the floating tube 3 through the connecting rope 4, the lower part of the nylon cloth 5 and the connecting rope 4 is connected by the steel pendant 7, and the connecting rope 4 passes around the fixed pulley 301 under the floating tube 3 and is connected to the balance steel tube 9. When the construction ship is dredging, the curtain system is fixed to the bow of the dredger 1. Before dredging, the rubber airbag 10 in the balance pipe is inflated, the balance pipe floats up, and the steel pendant 7 drives the connecting rope 4 and the nylon cloth 5 to sink.
