Description

Adjustable wave pressing plate for ship engineering

Technical Field

The utility model relates to the field of ship spare and accessory parts, in particular to an adjustable corrugated board for ship engineering.

Background

When a ship just starts, a stern propeller starts to rotate to generate wave flowers, most of the wave flowers are not pushed backwards, but generate a large amount of white foam wave flowers from the stern to the water surface like a hot water boiler, a water cavitation effect is generated, and the bubbles can directly decompose surrounding water into gas when the propeller starts to increase the rotating speed. These cavitation bubbles reduce the efficiency of the propeller, i.e. they do not generate backward flow to obtain a reaction thrust, they bubble up to the surface, and they also generate an excessive drag. After years of experiments, it is found that the foam is pressed to form useful thrust water flow only by adding a large plate at the stern, so the ship is called a press wave plate.
