A high-speed ship that draws water and pushes water from the bow side to the rear of the stern to obtain propulsion. [Effect] A large propulsive force can be obtained, a high-speed ship can be formed, a small turn can be avoided, and the ship can be stabilized.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a high speed ship, and more particularly to a ship intended for high speed traveling.

[0002]

[Prior art]

 Ships, which are structures floating on the water, carry customers and cargo, or are used for special purposes such as observation. In addition to human power and wind power, mechanical power is used as the power for propelling a ship. A propulsion engine is used as a propulsion device for mechanical power, and a paddle wheel (foreign car) is used as the propulsion device that constitutes it. , Spiral propeller, jet propeller, vane propeller, schneider propeller, aerial propeller, etc. However, in ships, it is common practice to mount the propulsion device on the stern side and rotate it by a prime mover installed in the center of the hull or stern to propel it. In the propulsion system, the method of attaching it below the water surface of the stern, rotating it, and pushing the water backward is generally adopted. In addition, in the ship concerned, the loadability of loading things, the buoyancy of floating on the water, and the characteristics according to the purpose of use are emphasized. High speeds such as hovercraft (ships) tend to be neglected. However, in recent years, due to the congestion of vehicles on land, high-speed traveling is also not possible, and when fast delivery of fresh food etc. is required, high-speed ship transportation has been reviewed. There is.

[Problems to be solved by the device]

 The purpose 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 be apparent from the entire description of the present specification.

[0004]

[Means for Solving the Problems]

 According to the present invention, a screw propeller is arranged in a multi-axial manner in the space below the bottom of the hull of a ship from the bow to the stern by contacting it below the surface of the water, and the screw propeller is rotated to cover the water and the bow side. It relates to a high-speed ship characterized by pushing water from the ship to the rear of the stern to obtain propulsive force.

[0005]

[Action]

 According to the present invention, the screw propeller is arranged in a multi-axial manner in the space below the bottom of the hull of the ship from the bow to the stern by contacting it below the surface of the water, and the screw propeller is rotated to cover the water and the bow side. Since the water from the ship is pushed to the rear of the stern to obtain propulsive force, a large propulsive force can be obtained and a high-speed ship can be obtained, and the screw propeller is installed from the bow to the stern. Because it is there, it is possible to get around the tight turns. Further, by arranging the screw propellers on multiple axes, it is possible to stabilize the ship.

[0006]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 (A) is a block diagram of a high-speed ship showing an embodiment of the present invention, FIG. 1 (B) is an aft view of the high-speed ship, and FIG. 2 (A) is an embodiment of the present invention. 2 (B) is a main part configuration diagram showing another embodiment of the present invention, and FIG. 2 (C) is a main part configuration diagram showing still another embodiment of the present invention. .

As shown in FIGS. 1 (A) and 1 (B), a screw-propeller 4 is arranged in a space 3 at the bottom of the bottom of a hull 2 of a ship 1 from the bow to the stern. The screw propeller 4 is brought into contact with water under the water surface as shown in the figure. The screw-propeller 4 is arranged on multiple axes. In this embodiment, an example in which the shafts are arranged on the left and right axes is shown, but they may be arranged on four axes, six axes, or the like. By arranging them on multiple axes, the speed can be further improved, the ship can be stabilized, and it is possible to deal with the case where the other fails. The screw propeller 4 can be rotated by a drive source (power source) 5. Examples of the engine that constitutes the drive source 5 include a steam engine (such as a turbine and a reciprocating engine), an internal combustion engine (including a gasoline engine and the like), an electric motor, a nuclear engine, and the like. It is advisable to arrange a plurality of drive sources (power sources), for example, from the bow to the stern, so that they can be dealt with when the other fails. By making the lower space 3 of the bottom of the ship from the bow to the stern in a tapered shape, it is possible to further contribute to speedup and the like.

A few examples of the screw-propeller 4 are as shown in FIGS. 2 (A), (B) and (C), but in the screw-propeller 4 shown in FIG. As shown in FIG. 1 (B), the underwater wing (6) portion may be a milling cutter having blades and lands. The screw propeller 4 shown in FIG. 2 (B) is an example of a screw propeller having a twist groove 7. A screw propeller 4 shown in FIG. 2 (C) is an example of a screw staircase having a spiral staircase.

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 embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say.
