Description

  The present invention relates to an energy-saving ship in which the frictional resistance of seawater is reduced and the ship speed is increased.

  In the past, the ship speed could only be commensurate with the fuel due to the frictional resistance of seawater.

  The purpose is to reduce the frictional resistance of seawater by blowing high-pressure air into the bottom of the ship and to make the ship more energy efficient than ever before.

In order to achieve the above-mentioned object, the present invention is directed to FIGS. 1 to 4 of the first means for solving the problems. In FIG. Is equipped with a check valve, connected to the pressurized air pipe is a relay pipe bent downward, connected to the relay pipe is a high-pressure air outlet pipe, branches the lower part of the pipe, It is attached through.
FIGS. 5 to 8 show an application example of the first problem solving means shown in FIGS. 1 to 4, in which air traps having a U-shaped or semicircular cross section are attached to both sides of a flat bottom. Further, instead of the relay pipe, the pressure air pipe and the high-pressure air blowing pipe are connected by a pressure-resistant flexible hose, and the lower end of the high-pressure air blowing pipe penetrates the bottom of the ship and is bent in the stern direction.
Note that the air entrainer can be applied to other problem solving means.

  FIGS. 9 to 11 of the second problem solving means show that a high-pressure air supply pipe is disposed in parallel with the keel in the upper part of the ship bottom to close the rear end, and a branched high-pressure air blowing pipe is provided on the lower surface of the pipe. Are connected at regular intervals, the lower end penetrates the bottom of the ship and is bent in the stern direction.

FIGS. 12 to 14 of the third problem solving means are examples of attachment to a ship with a barbus bow in service. The high pressure air blow-out pipe passes through the barbus bow and is bent in the stern direction. It is branched to and attached to the bottom of the ship.
In addition, the ship without a Barbus bow may arrange | position a relay pipe along a ridge, and a flexible hose may be used for a relay pipe.
FIGS. 15 to 19 are application examples of FIGS. 12 to 14 of the third problem solving means described above, in which an outboard high-pressure air blowing pipe is extended in the stern direction and attached to the bottom of the ship, the rear end is closed, High-pressure air outlets are opened at regular intervals on both sides of the tube.

The above-described high-pressure air blowing method may be appropriately increased according to the ship shape in both the lateral direction and the stern direction, and a welding elbow may be connected instead of penetrating through the bottom and bending in the stern direction.
In addition, the air compressor can be installed anywhere as long as it is higher than the flooding line, and if it is connected to the high-pressure air blowing pipe with a pressure-resistant flexible hose, it can be set freely, so only simple remodeling work is required. Thus, the present invention can be implemented.

The operation of the first problem solving means shown in FIGS. 1 to 4 is as follows. That is, when high-pressure air is blown out to the bottom of the ship at the time of navigation, an air layer is formed on the bottom of the ship, the air effectively acts on the bottom of the ship, and the frictional resistance between the ship bottom and seawater is reduced, thereby speeding up the stern.
In FIGS. 5 to 8 of the application example of FIGS. 1 to 4 of the first problem solving means, air traps are attached to both sides of the bottom of the flat bottom so that the blown air acts uniformly on the bottom of the ship. The ship speed can be further increased.
Flat-bottom ships increase in buoyancy and have less contact with seawater.Therefore, there are lateral shifts and instability in navigation, but air traps attached to both sides of the ship become resistance, and In addition to preventing, the air embedder can improve the progress in the stern direction.

  9 to 11 of the second problem solving means, high pressure air is blown out in a long range, so that an air layer is easily formed and the ship speed can be increased.

Since the third problem solving means of FIGS. 12 to 14 are also attached to a ship that is in service, the ship speed can be made faster than before.
12 to 14 of the application example of FIGS. 12 to 14 of the third problem solving means, high pressure air is blown out from both sides in a long range, so that an air layer is easily formed and the ship speed is further increased. Can do.

As described above, according to the present invention, when navigating, high-pressure air is blown out to the bottom of the ship to create an air layer, and while the ship is sailing in the air-sliding state, the frictional resistance of seawater can be reduced.
Therefore, the ship speed can be increased, fuel can be saved considerably, and it can be utilized as an energy saving ship.
