Document Type and Number:
Japanese Patent JP6991590
Kind Code:
B2
Abstract:
To provide a water surface floating article recovery ship capable of efficiently recovering a water surface floating article in a hull by controlling a water flow generated inside/outside the hull through driving of an outboard engine attached to a hull rear part, and an outboard engine duct.SOLUTION: A water surface floating article recovery ship 1 comprises: a hull body 2 in which a recovery chamber 21 for storing a water surface floating article F recovered inside is formed; buoyancy bodies 3 installed in both sides of the hull body 2; and an outboard engine 4 that is a driving source installed in a stern to drive a propeller 45. An outboard engine duct 5 roughly cylindrical and including the propeller 45 is installed below the outboard engine 4. A water flow discharged from the hull body 2 passes through the outboard engine duct 5 to become a jet. Thus, a water level difference in the recovery chamber 21 can be maintained constant.SELECTED DRAWING: Figure 1
