Description

Upward drainage type ship

One, the technical field

The invention relates to the field of water surface transportation, in particular to rapidity, economy at high speed and stability of a floating ship.

Second, background Art

The ship is divided into a floating ship, a diving ship, a gliding ship and an soaring ship according to the navigation state. The pontoon, which is a displacement vessel that travels on the water surface, and the submersible vessel are collectively called a displacement vessel. The floating vessels are widely used, such as container ships, bulk carriers, oil tankers, fishing boats, most warships and the like, and almost all medium and large ships are the floating vessels. In order to reduce the water resistance at high sailing speed, a V-shaped and sharp-thin bow is generally adopted for the floating vessel.

The bow of the floating ship applies pressure to water in front of the bow to squeeze the water out and move forward, the drainage direction of the bow of the floating ship is mainly horizontal and downward, and the outside and the underside of the water in front of the bow are water, so that wave-making resistance is generated by making waves; wave making resistance can be sharply increased along with the increase of the ship speed, and is a main factor influencing high navigation speed or high energy consumption of the ship at the high navigation speed. At present, the method for inhibiting bow wave-making resistance of a medium-large floating vessel mainly optimizes the shape of the vessel and increases a bulbous bow. The stability of the pontoon at high speed also needs to be enhanced.

Third, the invention

The purpose of the present invention is to improve the rapidity, economy at high speed, and stability of a floating vessel.

The technical scheme of the invention is as follows: a kind of floating vessel, including hull and power system, there are a pair or more protruding structural components outside the said hull fore-board, two protruding structural components in each pair are set up outside the left and right fore-boards separately and regard median longitudinal section as the symmetry; the upper surface of each protruding component is a forward inclined plane, and the inclined plane is gradually increased from front to back; and a sealing surface is arranged below the inclined surface, the sealing surface and the inclined surface form a watertight sealing body, and the sealing body is arranged outside a ship body header through a fastening piece.

The floating vessel in the technical scheme is a V-shaped and sharp-thin bow.

The two protruding members are respectively arranged outside the left header and the right header and are symmetrical in the middle longitudinal section, and the two protruding members are called a pair of protruding members in the invention.

In the technical scheme, the direction from front to back is from the front to the back, the front direction refers to the direction of a bow, and the back direction refers to the direction of a stern.

The fastener and the sealing body are the protruding components.

The invention can reduce wave making resistance of the bow of the floating vessel during high-speed forward movement, and the method comprises the following steps: when the floating ship moves ahead at high speed, a part of water in front of the bow flows upwards through the inclined plane, so that wave making resistance generated by diversion drainage and horizontal or downward drainage is reduced.

If the inclined surface is not optimized, water resistance is generated on the back surface of the inclined surface, and the sealing surface is used for inhibiting the water resistance.

The invention has the advantages of

The technical scheme of the invention is different from the background technology: the drainage direction of the invention is mainly upward, not horizontal or downward, which can increase drainage channels; above the water surface is air, not water; different settings (number of inclined planes, inclination, position, area, etc.) help to optimize the ship's travelling wave.

The invention can improve the stability of the floating vessel: 1. as is known, when a floating vessel moves ahead at a high speed, the bow can be lifted upwards and easily generate pitching, and when the floating vessel moves ahead, the inclined surface can generate downward pressure on the bow, so that the bow can be suppressed from being lifted upwards, and the pitching stability of the floating vessel is improved and is very important for a carrier; 2. the protruding component can play a role similar to a fin stabilizer, and the rolling stability of the floating ship is improved.

In conclusion, the wave-making resistance of the bow of the floating ship can be reduced when the floating ship moves forwards at a high speed, and higher speed can be realized under the same thrust, or the energy consumption is lower under the same high speed; the stability of the floating ship can be improved; the protruding component is arranged outside the bow, has simple structure and is more compact than the bulbous bow.
