Device for reducing ship navigation resistance and assisting in ship turning

Abstract

The present invention provides a device for reducing ship navigation resistance and assisting in ship turning. A t-branch pipe is arranged at the lower front end of a ship bow water line, the t-branchpipe is connected with the front, the left port and the right port of the ship bow; at least one control valve (or a conduction device) is installed at the t-branch pipe, and a control panel of slavedriving can control the deviation of the valve (or the conduction device); water flows in the t-branch pipe at the front end of the ship bow and flows out from shunts at two sides to reduce the pressure resistance of the ship bow and increase the traveling speed of the ship or reduce energy consumption; when the valve (or the conduction device) is located at the center of the t-branch pipe, the stream meanly flows out through the shunts at the two sides without influence on ship heading; and when the valve (or the conduction device) allow the stream to deviate the shunt at one side to allow the ship to turning to the other side.

Description

technical field [0001] The invention relates to a device capable of reducing ship navigation resistance and assisting ship steering, especially a resistance reducing mechanism arranged at the bow of a ship, which also has the purpose of assisting steering. Background technique [0002] Usually, when the ship moves forward, the front end of the ship is subjected to the greatest pressure resistance, which will reduce the speed of the ship and increase energy consumption; while the general traditional improvement method is to modify the ship into a streamlined shape, but it still cannot avoid the pressure resistance of the ship. The maximum pressure resistance at the front end needs to be reviewed and improved. [0003] Press, existing ships 100, such as Figure 6 As shown, a screw propeller 101 is usually arranged under the stern of the ship 100, and a rudder plate 102 is arranged behind it, and the direction of travel of the ship 100 is changed by controlling the rotation ang...

Problems solved by technology

However, the existing ship 100 is propelled by the screw propeller 101 at the rear, and its thrust is applied to the stern. When the ship 100 turns by turning the rudder plate 102, the force of the water flow impacting the rudder plate produces a lateral component force on the stern, but also At the same time, the longitudinal component force is generated, that is, the reverse propulsion force, which reduces the speed of the ship.

During sailing, due to the influence of wind, current and waves, the ship cannot maintain a constant direction and advances in a "zigzag" shape. It needs to be corrected with the rudder all the time, so the aforementioned reverse propulsion cannot be avoided.

The maximum rudder angle of the ship is limited, so the minimum turning radius is limited. In an emergency, it is impossible to make a sharper steering to avoid other ships or obstacles in the water. Therefore, the existing ship steering system still has great room for improvement.
