The invention discloses an anti-bubble channel type side thrust cover which is completely consistent with the curve shape of the hull, and belongs to the technical field of shipbuilding. Including: the outer plate of the hull; the bow thruster tunnel body, which is set inside the bow; two box-shaped bases, which are respectively fixed at both ends of the bow thruster tunnel body, and There are mounting bolt seats and sealing strips for the outer ring at the connecting position of the ring, and sealing strips for the inner ring at the connecting position of the inner ring; two detachable outer plates, the inner surfaces of the two detachable outer plates are respectively connected with two box-shaped bases, each A detachable outer panel is provided with a watertight protective box, and the watertight protective box is provided with an actuator, the actuator is connected to the rotating shaft, and the rotating shaft is fixedly connected to a plurality of blades, and the several blades are arranged on the outer surface of each detachable outer panel. The invention provides an anti-bubble channel type side thrust cover that is completely consistent with the curve of the ship hull. When the side thrust is not in use, the cover is closed to improve the resistance of the ship and greatly reduce the leakage of air bubbles at the tunnel mouth.
Description
technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an anti-bubble channel type side thrust cover completely consistent with the line shape of the hull surface. Background technique [0002] Ships are composed of thousands of parts and are related to almost every industry sector. In addition to the unique hull construction technology, shipbuilding also involves various fields such as machinery, electricity, metallurgy, architecture, chemistry, and arts and crafts. Therefore, shipbuilding is a comprehensive technology based on all industrial technologies, reflecting a country's industrial technology level. [0003] Due to the different navigation areas, missions and requirements of ships, ship products have the characteristics of many varieties and small production batches. At the same time, with the reduction of the number of people on board, the improvement of the degree of automation, and the special operation requirement...
