Description

technical field

[0001] The invention relates to the technical field of ships, in particular to a cover plate structure for an opening of a ship side thruster outer plate. Background technique

[0002] The side thruster for ships is generally installed at the bow and / or stern of the ship, and as close to the bow or stern as possible. The opening on the side thruster outer plate of the side thruster is generally circular and has a large diameter, about 0.5m to 3.5m. m, for the tunnel-type side thruster at the bow, the opening is located at the bow, and the opening is easy to make the outer plate uneven. Since the outer plate of the hull is generally streamlined, the openings set on the outer plate will cause the shape of the outer plate to be uneven, resulting in More resistance, in order to reduce the resistance generated by the opening of the outer plate, the opening is generally covered with a cover plate or grille. The cover plate or grille in the prior art is generally m...
