Turn-free boat

Abstract

A ship not running over in great storms is provided, which is a ship body with a double shell structure by a movable shell surrounding the inner cabin. A keel is movably connected with the shell and is fixedly connected with the inner cabin; the bottom area of the inner cabin is provided with locating movable wheels connected with a fixed slide rail corresponding to the inner wall of an outer cabin. Both sides out of the outer cabin are provided with hydrofoils and the bottom of the outer cabin is provided with a stable center of gravity block, which can make the outer cabin restore the stable state that the center of gravity is downward in the storms automatically. The inner cabin is provided with a lockup device and can be fixed on a locating slide rail of the outer cabin during sailing under normal sea condition; the ship can sail like the common ships, when under the severe sea condition with great storms, a locking brake of the inner cabin is loosened; the inner cabin and the outer cabin share the series position of the center shaft; the center of gravity of the ship body is on the bottom of the inner cabin; the inner cabin cooperates with the locating slide rail to move through the locating movable wheels however the shell sways left and right in the storms and keeps the stable and balanced state with unchangeable center of gravity, therefore, the ship can not cant over in the storms.

Description

technical field [0001] The invention relates to a ship structure, in particular to a ship structure design capable of resisting wind and waves and not tipping over. Background technique [0002] In order to prevent the existing ships from shaking or even tipping over when encountering wind and waves, they generally use heavy ballast to lower the center of gravity of the hull, increase the draft of the hull, and improve the performance of the hull against wind and waves. However, if the draft of the hull is too large or the center of gravity of the hull is too large Low, the resistance of the hull is increased, and the driving speed and maneuverability are reduced. It is impossible for small boats to increase the weight of ballast, and the design of the hull improves the anti-wind and wave performance. For improving the anti-wind, wave and anti-overturn performance of small boats, people propose multiple design schemes. For example, CN1605544A proposes a hull, which is built ...

[0002] In order to prevent the existing ships from shaking or even tipping over when encountering wind and waves, they generally use heavy ballast to lower the center of gravity of the hull, increase the draft of the hull, and improve the performance of the hull against wind and waves. However, if the draft of the hull is too large or the center of gravity of the hull is too large Low, which increases the resistance of the hull and reduces the driving speed and maneuverability

It is impossible for small boats to increase the weight of ballast, and the design of the hull improves the anti-wind and wave performance. For improving the anti-wind, wave and anti-overturn performance of small boats, people propose multiple design schemes. For example, CN1605544A proposes a hull, which is built on the hard structure Tubular members are arranged around or locally, and the tubular members are inflated to increase the buoyancy and stability of the hull. Another example is CN20030128740, which proposes to set rollers on both sides of the hull to connect with the hull with rollers, and to provide ballast at the bottom of the ship. The above two Although the structure has the functions of anti-wind and wave and anti-overturning, it is at the cost of reducing the volume of the hull, reducing the speed of sailing and maneuverability, especially the rollers on both sides of the hull, and when one side of the ship faces the wind and waves, one roller rotates , the roller on the other side does not move, but increases the instability of the hull and makes it easier to tip over
