Improve as one, in naval ship water, in damper housing, set up the container that can deposit powerful wet etchant, in the time that drill bit destroys ship shell, corrosive agent is injected into by conduit on the destruction face of drill bit, strengthen the damage effect to warship body.Corrosive agent container is deformable flexible plastic structure, advances the spring of drill bit simultaneously to corrosive agent container certain pressure, makes corrosive agent pass through conduit and constantly injects bit breakage face.

Improve as one, for preventing that drill bit lost efficacy rapidly at corrosive agent environment, adopted corrosion resistant ceramic bit.

Improve as one, according to the buoyant characteristics of object, damper overall weight is designed to buoyancy in water with it to be equated, after damper spreads in water, can be suspended in water, naval vessel is through out-of-date, and damper will be adsorbed onto below the water line on naval vessel, increase found difficulty, and maintenance difficulty.

Improve as one, it is basic identical with the color of the waters water that scatters that damper is manufactured material color used, makes enemy be difficult for the naked eye finding.

Improve as one, the density of different waters water is variant, opens the aperture of a with closure on damping body, before coming into operation, according to sea data, corresponding counterweight is placed wherein, to guarantee the suspension requirement of damper in water.Also solved damper weight differential during fabrication simultaneously.

Improve as one, counterweight holding chamber is opened on the vertical plane of water stream channel, during damper aborts after, due to Action of Gravity Field, below counterweight holding chamber side remains on, in the time that damper is adsorbed onto on naval vessel, guarantee water stream channel and current in the same way.

The specific embodiment

In sum, the technology of the present invention forms damper in naval ship water, and low cost of manufacture is easy to scatter, and distribution method is various.Too much the naval vessel of absorption damper, can reduce the speed of a ship or plane; The damage that naval vessel is suffered, below water line, reparation difficulty is large; Due to strong magnetic exist, strengthened the triggering signal intensity of submarine mine, torpedo magnetic fuze.
