Water traffic transportation tool

Abstract

The invention relates to a water traffic transportation tool. The water traffic transportation tool comprises a boat bottom (1), boat sides (2), a deck (3), a surge guide groove (4) and a wave pressing and guiding baffle (5). The surge guide groove is arranged in a space between the bottom which vertically indents into the boat bottom and the deck and extends from the bow to the stern, the transverse section of the surge guide groove is arc-shaped, and the ceiling of the longitudinal section is low at the front and high at the back. The top transverse section of the wave pressing and guiding baffle is arc-shaped, and the ceiling of the longitudinal section is low at the front and high at the back. The water traffic transportation tool can be designed into forms of single, double and trisome. The water traffic transportation tool has good hydrodynamics characteristics, is capable of getting rid of large resistance of water greatly so as to improve ship speed and ship course stability, in addition, the boat can turn stably and quickly with small turning radius and the danger of overturn can not happen, and therefore maneuverability, flexibility and seakeeping of the water traffic transportation tool are improved greatly.

Description

technical field [0001] The invention relates to a water transportation tool, which is used in the technical field of water transportation. Background technique [0002] The means of transportation currently used for waterway transportation, that is, various boats are: [0003] General displacement boats have good stability and can meet the needs of large, medium and small tonnages, but the draft is relatively deep and the water resistance is large. The larger the tonnage, the deeper the draft, which leads to high energy consumption and it is difficult to improve speed. [0004] Hydrofoil boats reduce the water resistance due to the shallow draft and increase the speed, but their maneuverability, seaworthiness and maneuverability are poor. It is difficult to navigate in turbulent currents and shallow rivers, and it is difficult to navigate smoothly in strong winds and waves. [0005] Hovercraft, because it gets rid of the resistance of water, improves the speed of the ship...

AI Technical Summary

Problems solved by technology

However, in order to improve its own heading, lateral stability and maneuverability, the V-shaped cross-section bottom of the ship is adopted, which leads to an increase in the wetted surface and increased frictional resistance; and the lift of the bow is large while the lift of the stern is relatively small, resulting in the water surface at the bow of the boat. Increased swell height increases resistance, is sensitive to wave response, and has poor anti-wind and wave performance

[0007] The above-mentioned types of boats, except for displacement boats, have a relatively large tonnage limitation, which is another common weakness of them

In addition, the general surface transportation vehicles in the prior art have restrictions on the speed due to their structural form. When the speed is greater than 50 knots, the phenomenon of poor stability will occur. If the propulsion power is increased, not only will the speed increase If you don't go, it will also lead to loss of stability and the danger of overturning
