Multi-hull ship

Abstract

The invention provides a multi-hull ship. The multi-hull ship comprises a main hull and sheet bodies symmetrically arranged at the bottoms of the two sides of the main hull. The blade body is streamlined, and a water-jet propeller is arranged at the tail of the blade body; the sheet bodies are connected with the main ship body through damping mechanisms. The multi-hull ship is of a composite hull design, and the sailing stability and rapidity of a catamaran and the high load-carrying capacity of a common ship type are considered at the same time. The damping mechanism is additionally arranged, meanwhile, the sheet bodies and the main ship body are movably connected, and the degree of freedom between all the parts is improved, so that the ship body deforms under large storm waves, the main ship body is kept stable in cooperation with the damping mechanism, ship body swaying caused by the storm waves is reduced, and the adaptability of the ship body to the water condition is improved. Meanwhile, fewer parts and modular design are adopted, and each module is simple in structure, high in universality, capable of being quickly disassembled and assembled and easy to transport and store. All parts of the ship body are made of high-strength light materials, so that the self weight is reduced, and the bearing capacity is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a multihull ship. Background technique [0002] The hydrostatic resistance and power consumption of common single displacement ships have a great influence on their speed. Monohull planing craft is greatly affected by water surface waves at high speed, resulting in poor stability. When the traditional catamaran sails at high speed, due to its slender body, turbulence occurs when driving against the waves, and the hull and the main hull are rigidly fixed, which causes the hull to transmit the turbulence to the main hull, resulting in poor seakeeping. [0003] When taxiing at high speed, under the force of water, the bottom of the ship will be subjected to the constant changing supporting force component perpendicular to the surface of the bottom of the ship, which will cause violent shaking, resulting in the phenomenon of "leapfrog", causing people to feel strong discomfort, and th...

Problems solved by technology

Single-hull planing boats are greatly affected by water surface waves at high speeds, resulting in poor stability

When the traditional catamaran sails at high speed, because of its slender hull, it will generate bumps when driving in head-on waves, and the hull and the main hull are rigidly fixed, which will cause the hull to transmit the bumps to the main hull, resulting in poor seakeeping

[0003] When gliding at high speed, under the force of water, the bottom of the ship will be subjected to a constantly changing force component perpendicular to the bottom surface, which will cause violent swaying and "leapfrog" phenomenon, which will cause strong discomfort to the personnel, and the hull structure may also be damaged. When the roll is too large, this phenomenon may cause the objects in the cabin to slide, damage the navigation and propulsion equipment on the ship, and even cause the ship to roll over or structurally damaged
