Device for reducing the sailing drag and assisting the steering of the ship

Abstract

The invention provides a device which can reduce the drag and assist the steering of the ship, mainly to set up a 3-way pipe in the bow where is below the water level. The 3-way pipe leads to three openings at the stem, the port side and the starboard side respectively. At least one control valve (or deflector) can be provided in the 3-way piping system. The valve (or deflector) can be controlled from the bridge, with a diversion device. When the ship sails forward, water flows into the 3-way pipe from the forward pipe, distributed to both side pipes and then outflow, so that it can reduce the pressure drag to the stem, improve the ship's speed and save bunker. When the valve (or deflector) is set as neutral, the water will be distributed evenly to both side pipes, which will not affect the ship's heading. When the valve (or deflector) deflects more water to either side's pipe, the ship will turn to the opposite side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Referring to the FIG. 1. The present invention can reduce the drag and assist the steering of the ship. In addition to the traditional steering system including the propeller 101 and the rudder 102 where below the stern of the ship 10, an auxiliary steering system of 3-way pipe 11 is installed in the bow below water level, which leads to the stem and both sides' hull of the ship. When the ship 10 sails forward, the water flows into the 3-way pipe from the stem side's pipe, outflows evenly from the pipes at both sides of the ship, so that it can reduce the overall drag of the ship 10, increase speed or save bunker. When ship turning is needed, by adjusting the water flow toward either side pipes can achieve the requirement.

[0025] Referring to FIGS. 2, 3, 4 and 5. The 3-way pipe 11 is in the form of an inverted Y-shape or inverted T-shape. According to the principle of fluid mechanics, when the ship 10 sails forward, the water flows into the 3-way pipe 11 from the opening at the stem, and being discharged from both side openings of the ship 10. It can reduce the overall drag of the ship 10 and accordingly, increase the speed of the ship 10 or save bunker.

The incoming water from the forward pipe will turn to the right pipe and outflow (as indicated by the arrow). The ship 10 turns to the port side accordingly.

[0028] When the ship 10 intends to turn to starboard side, the actuator 13 is actuated from the console 12 on the ship 10, and the valve 14 located in the middle of the 3-way pipe 11 is driven to the right as shown in the FIG. 2-2, so as to block the right pipe of the 3-way pipe 11. The incoming water from the forward pipe will turn to the left pipe and outflow (as indicated by the arrow). The ship 10 turns to the starboard side accordingly.

[0029] FIG. 3 is the 2nd embodiment of the present invention to change the heading of the ship 10. In addition to steer by the rudder 102 as shown in the FIG. 1, the present invention can be used as an auxiliary steering device.

[0030] In operation, when the ship 10 intends to turn to the port side, the actuator 13 is actuated from the console 12 on the ship 10, and the stopper 15 located in the middle of the 3-way pipe 11 is driven to the left as shown in the FIG. 3-1, so as to block the left pipe of the 3-way pipe 11. The incoming water from the forward pipe will turn to the right pipe and outflow (as indicated by the arrow). The ship 10 turns to the port side accordingly.

[0031] When the ship 10 intends to turn to starboard side, the actuator 13 is actuated from the console 12 on the ship 10, and the stopper 15 located in the middle of 3-way pipe 11 is driven to the right as shown in the FIG. 3-2, so as to block the right pipe of the 3-way pipe 11. The incoming water from the forward pipe will turn to the left pipe and outflow (as indicated by the arrow). The ship 10 turns to the starboard side accordingly.

[0032] FIG. 4 is the 3rd embodiment of the present invention to change the heading of the ship 10. In addition to steer by the rudder 102 as shown in the FIG. 1, the present invention can be used as an auxiliary steering device.

[0033] In operation, when the ship 10 intends to turn to the port side, the actuator 13 is actuated from the console 12 on the ship 10, and the valve 16 located at the left side of the 3-way pipe 11 is driven to the right as shown in the FIG. 4-1, so as to block the left pipe of the 3-way pipe 11. The incoming water from the forward pipe will turn to the right pipe and outflow (as indicated by the arrow). The ship 10 turns to the port side accordingly.

[0034] When the ship 10 intends to turn to the starboard side, the actuator 13 is actuated from the console 12 on the ship 10, and the valve 16 located at the right side of 3-way pipe 11 is driven to the left as shown in the FIG. 4-2, so as to block the right pipe of the 3-way pipe 11. The incoming water from the forward pipe will turn to the left pipe and outflow (as indicated by the arrow). The ship 10 turns to the starboard side accordingly.

[0035] FIG. 5 is the 4th embodiment of the present invention to change the heading of the ship 10. Except to steer by the rudder 102 as shown in the FIG. 1, the present invention can be used as an auxiliary steering device.

[0036] In operation, when the ship 10 intends to turn to the port side, the actuator 13 is actuated from the console 12 on the ship 10, and the deflector 17 located in the middle of 3-way pipe 11 is driven counter-clockwise as shown in the FIG. 5-1, so as to deflect the water to the right pipe of the 3-way pipe 11. The incoming water from the forward pipe will turn to the right pipe and outflow (as indicated by the arrow). The ship 10 turns to the port side accordingly.

[0037] When the ship 10 intends to turn to the starboard side, the actuator 13 is actuated from the console 12 on the ship 10, and the deflector 17 located in the middle of 3-way pipe 11 is driven clockwise as shown in the FIG. 5-2, so as to deflect the water to the left pipe of the 3-way pipe 11. The incoming water from the forward pipe will turn to the left pipe and outflow (as indicated by the arrow). The ship 10 turns to the starboard side accordingly.

[0038] In summary, the present invention is capable of reducing the drag and assisting the steering of the ship, mainly in the form of a 3-way pipe in the bow below water level, which is provided with at least one valve (or deflector). A valve (or deflector) is located in the neutral position of the 3-way pipe, when the ship sails forward and the water came from the front pipe will be distributed evenly to the other two side pipes and outflow, in which way it can reduce the ship's drag, increase the speed of the ship or save bunker. When the ship intends to change the heading, in addition to steer the traditional rudder, the actuator can be actuated to drive the valve (or deflector) in the 3-way piping system so that more water flows to either side's outlet, assists the vessel to turn to the opposite side. The invention has never been made public or has been found in any publications, therefore it is in line with the provisions of the patent law. Thus the inventor is hereby applying for a patent.
