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, curr...

Embodiment Construction

[0035] see figure 1 As shown, the present invention can reduce the ship navigation resistance and assist the ship turning device, except retaining the original screw propeller 101 and rudder plate 102 and other steering systems under the tail end of the ship 10; A three-way pipe 11 is set at the front end of the line, leading to the front of the bow and the outside of the hull on the left and right sides; The overall resistance of the ship 10 can be reduced to save fuel and reduce energy consumption; when steering is required, the water flow in the tee pipe 11 leading to both sides can be adjusted to assist steering.

[0036] Cooperate Figure 2 to Figure 5B As shown, the three-way pipe 11 is shaped like an "inverted Y" or "inverted T" structure. According to the principle of fluid mechanics, when the ship 10 is on the way, the water flow at the front end of the bow enters the three-way pipe 11. Distributing the flow to both sides of the ship 10 can reduce the overall resis...

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...
