Ship with laterally and outwards expanded and stored device

Abstract

A ship with a laterally and outwards expanded and stored device comprises a ship body. Inlaid resistance plates are arranged on the positions, on the left side and the right side of the ship body andon the area from the position below the water line to the ship bottom, of the ship body in the direction from the nose to the stern, the outer surfaces of the resistance plates are components of the surface of the ship body, and the inner sides of the resistance boards are connected with the ship body through telescopic arms fixed to the ship body. Through stretching out or drawing back of the telescopic arms, the resistance plates can be in an expanded or inlaid state on the ship body. According to the ship with the laterally and outwards expanded and stored device, vertical resistance obtained through expanding of the resistance plates on one side of the ship body resists side lurching torque on the other side of the ship body, and the instability of the ship body in sailing during steering is overcome; through lateral thrust generated by the flowing speed difference, caused by the resistance plates on one side, of water flows of the two sides of the ship body, the steering efficiency of the ship can further be improved; and when the resistance plates keep in the inlaid state, the ship body molded line appearance is unchanged, and the sailing efficiency of the ship is not affected.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship with a laterally outwardly expanding and retracting device, which can keep the ship body stable and improve the turning efficiency when the ship turns. Background technique [0002] Currently known ships, when turning during navigation, will cause the hull to "incline" or "externate" due to the combined effect of the lateral inertial force of the hull, rudder force and hydrodynamic force, which cannot be solved by current technology. [0003] Presently known ship turns during sailing, and mainly changes direction by the rudder positioned at the stern or the propeller at the stern to complete the steering. [0004] In order to improve the steering efficiency of the ship, the method of installing bow thrusters below the waterline at the bow of the ship can make the ship adjust the bow direction when it is in port, but it does not work for steering during navigation. Changing ...

AI Technical Summary

Problems solved by technology

[0004] In order to improve the steering efficiency of the ship, the method of installing bow thrusters below the waterline at the bow of the ship can make the ship adjust the bow direction when it is in port, but it does not work for steering during navigation. Change the shape line of the hull bow surface, resulting in increased resistance and reduced navigation efficiency

[0005] In order to improve the steering efficiency of the ship, increasing the number of rudder blades at the stern will increase the complexity of the rudder equipment, the weight of the hull, and the cost. Therefore, in actual use, unless there are special requirements, the minimum number of rudders is always used.
