Description

Vessel capable of moving the hull up and down

The present invention relates to a ship capable of moving a hull up and down.

In general, a ship acquires forward thrust by pushing water by transmitting power generated from a prime mover such as an internal combustion engine and an electric motor to a screw through a rotating shaft.

The efficiency of the screw is only 70~80% in the case of a large craft and 50~60% in the case of an elongated high-speed craft. In order to increase the efficiency of such a screw, it is impossible with the existing screw, and a method of improving the linear shape to improve the ship speed is used. The method of rotating the screw at a higher speed is used by increasing the

However, there is a limit to the power of a marine diesel engine, and when the screw rotates at high speed in water, the surrounding water pressure falls below the saturated water vapor pressure and bubbles are generated, that is, cavitation occurs. .

Therefore, the maximum ship speed that can be realized with the normal hull shape and thruster does not exceed 45 knots (83.34 km per hour).

The existing screw had a spiral shape in order to simultaneously inhale and discharge while rotating around one axis in any way, and the surface of the wing of the screw had to be smooth. It is to minimize the frictional resistance generated on the surface of the blade of the screw, but the frictional resistance still occurs and the energy efficiency is not good because it is sucked and discharged through the friction of the fluid in the water.

In the past, a belt-type propulsion method was introduced instead of the screw method, but it is a method in which the web is rotated by attaching a webbing to the belt.

In this way, when the fins come down to the surface, they hit the surface and lift the hull upwards, so it does not help the forward thrust. In other words, power loss caused by hitting the water surface occurs, and proper propulsion is not achieved by lifting the hull.
