1. A dangling net cloth device for suppressing flutter of a sea-crossing bridge, wherein the dangling net cloth device for suppressing flutter of a sea-crossing bridge comprises cable chains, first buckles, node connectors, net material, high-strength cloth, balance weights, ropes, second buckles and suspension rings; each cable chain is connected with the node connectors through the first buckles arranged on both ends; a criss-crossed network system is formed by a plurality of cable chains, first buckles and node connectors to provide support for the dangling net cloth device; the net material is laid above the network system and is connected with the cable chains to form a cable net; the water-impermeable high-strength cloth is laid above the cable net and connected with the cable net to form integrated net cloth; the balance weights are suspended below the node connectors; each rope is provided with the second buckles on both ends, connected with a node connector on the lower end, and connected with a suspension ring fixed below a main beam on the upper end, thus the dangling net cloth device is suspended below the main beam and immersed in water; for a bridge already built, the suspension rings are added to the bottom of the main beam in a later phase; and for an unbuilt bridge, the suspension rings are arranged in advance when making the main beam.
