Novel automatic jet floating type breakwater and wave eliminating method thereof

The invention discloses a novel automatic jet floating type breakwater. The breakwater comprises a base which sinks underwater and a floating body which floats on the water; the base is connected with the floating body by an anchor chain; a water pump is disposed in the floating body; the water inlet of the water pump is arranged on the lower part of the floating body, and the water outlet is arranged on the head sea side of the floating body; a single-chip microcomputer is mounted in the base; a pressure type wave height gauge is disposed on the front of the head sea side of the base; and the single-chip microcomputer is electrically connected with the pressure type wave height gauge and the water pump, and controls the switch on/off and volume of the water pump based on the data from the pressure type wave height gauge. The invention also discloses a wave eliminating method using the novel automatic jet floating type breakwater mentioned above, wherein, the wave elimination is performed by the floating body itself according to the designed wave condition of the breakwater. The novel automatic jet floating type breakwater disclosed by the invention can normally eliminate waves by the floating type breakwater itself, and can jet horizontal flow on the head sea side to enhance wave elimination performance when the single-chip microcomputer detects an extreme wave condition by the pressure type wave height gauge, therefore saves cost and meets the practical needs well at the same time.
