Abstract

PROBLEM TO BE SOLVED: To attain large propelling force and a high speed by rotating screw propellers arranged in a pipe from the bow to stern at the lower section of a hull, sucking water into the pipe from the bow side, and ejecting the water backward from the stern side. SOLUTION: A pipe 3 is provided in parallel with the advancing direction of a ship 1, from the bow to stern at the bottom side lower section of the hull 2 of the ship 1, and screw propellers 4 are arranged in the pipe 3. The screw propellers 4 are arranged into multiple axes centering on the intermediate axis of the hull 2, further improve speed, stabilize the ship 1, and cope with the case when the other fails. Steam engines, internal combustion engines, motors, nuclear engines, or power engines utilizing compressed air are used for the engines constituting the drive sources of the screw propellers 4, and multiple engines are dividedly arranged from the bow to stern to cope with the failure of the other engine. The protective net 5 of the screw propellers 4 is provided at the tip section of the pipe 3, thereby large propelling force is obtained to realize a high-speed cruise.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ship,
About high-speed ships.

[0002]

2. Description of the Related Art Ships, which are structures floating on water, carry passengers and cargo, or are used for special purposes such as observation. The power to propel the ship includes human power, wind power,
There is mechanical power, and those with mechanical power use a propulsion engine as its propulsion device, and as a propulsion device that composes it,
Waterwheels (foreign vehicles), spiral propellers, jet propellers,
There are a vane propeller, a Schneider propeller, an air propeller and the like. However, in a ship, generally, the propulsion device is attached to the stern side, and the propulsion is performed by rotating the propulsion device by a motor installed at the center of the hull, the stern, or the like. In general, a propulsion system is adopted in which the stern is mounted below the water surface of the stern, rotated, and pushed while pushing water backward. In addition, in the ship, emphasis is placed on the loadability of loading objects, the buoyancy of floating on the water, and the characteristics according to the purpose of use. High speed such as a hovercraft (ship) is often neglected. However,
In recent years, high-speed traveling has not been maintained due to traffic congestion on land, and when early delivery of perishables and the like is required, ship transportation with high speed is being reviewed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a technique capable of solving the drawbacks of the prior art. The above and other objects and novel features of the present invention will become apparent from the entire description of the present specification.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a screw propeller is disposed inside a pipe from the bow at the lower part of the hull of the ship to the stern, the screw propeller is rotated to drain water, and The present invention relates to a high-speed ship, wherein water from the side is sucked into the inside of the pipe and jetted rearward on the stern side to obtain a propulsion force.

[0005]

In the present invention, a pipe is piped from the bow to the stern at the lower part of the hull of a ship, a screw propeller is installed inside the pipe, and the screw propeller is rotated to drain water, Since water from the bow side is rapidly sucked into the inside of the pipe and spouted abruptly to the rear on the stern side to obtain a propulsive force, a large propulsive force can be obtained and a high-speed ship can be formed.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a high-speed ship showing an embodiment of the present invention, FIG.
FIGS. 3A to 3D are explanatory diagrams each showing an example of a screw propeller used in the present invention.

As shown in FIG. 1, a pipe 3 is provided in a lower part of a hull 2 of a ship 1 from a bow to a stern in a direction parallel to a traveling direction of the ship, and a screw is provided inside the pipe 3.
The propeller 4 is provided. The screw propeller 4 is
As shown in FIG. 2, the hull 2 may be arranged in multiple axes around the center axis. In this embodiment, an example is shown in which two axes are arranged on the left and right. However, four axes, six axes, or the like may be used.
By arranging in multiple axes, the speed can be further improved, the ship can be stabilized, and the case where the other has failed can be dealt with. The screw propeller 4 is a driving source (power source)
(Not shown). Engines constituting the drive source include a steam engine (including a turbine and a reciprocating engine), an internal combustion engine (including a gasoline engine, etc.), an electric motor, a nuclear engine, a power engine using compressed air, and the like. No. The drive source (power source) may be divided into a plurality of parts, for example, from the bow to the stern, so as to be able to cope with a case where the other is out of order. In the present invention, since the screw propeller 4 protrudes to the bow side, a screw-propeller protection net 5 may be provided at the tip of the pipe 3. Thereby, the screw propeller 4 can be protected from adhesion of algae in seawater and the like.

As the screw propeller 4, various types can be used. As the screw propeller 4, the one shown in FIG. 1 or the one having six blades (water wings) as shown in FIG. 3A can be used. In the screw propeller 4 having six blades (water blades), the six blades (water blades) may be a milling cutter having blades and lands. Another few examples of the screw propeller 4 are shown in FIG.
(B) to (D). The screw propeller 4 shown in FIG. 3B is an example of a screw propeller having a twist groove 7. The screw propeller 4 shown in FIG.
An example of a screw propeller with a spiral staircase is shown. FIG.
The screw propeller 4 shown in (D) shows an example using a screw used inside a cylinder of a plastic injection molding machine.

Although the invention made by the present invention has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the gist of the invention. Needless to say.

[0010]

The effects obtained by the representative ones of the inventions disclosed in the present application will be briefly described as follows. That is, according to the present invention, the screw propeller arranged from the bow side to the stern side rapidly draws in seawater and spouts the seawater suddenly rearward on the stern side, so that a large propulsion force is obtained. At the same time, it enables high-speed running. In addition, such a high speed can be achieved, and a small turning can be achieved due to its structure, and the ship itself can be stabilized.
