Problems solved by technology

At present, the main measure for ships to reduce turbulence is to add ballast weights or pressurized water tanks at the bottom of the cabin to lower its center of gravity, but this will increase the dead load, reduce the effective load, and increase energy consumption and Operating costs

Embodiment Construction

[0017] In this specific embodiment, the diving chamber composed of straight-through pipes with a rectangular cross section and straight-through pipe bundles with a circular cross-section is taken as an example. In fact, the diving chamber can be composed of straight-through pipes or pipe bundles with various shapes in cross-section.

[0018] As shown in Figures 1 and 2, it is a device for reducing lateral pitching of ships. The diving cabin 2 is composed of a smooth straight-through pipe with a rectangular cross section, which runs through the front and back, and a plurality of smooth longitudinal partitions 3 are arranged in the cabin. The diving chamber 2 is directly installed in a certain depth under the ship 1 , and its longitudinal axis of symmetry is consistent with the navigation direction of the ship 1 .

[0019] As shown in Fig. 3 and Fig. 4 is another kind of device that reduces ship's lateral pitching, and the submersible cabin 5 that is combined by the smooth straig...

Abstract

The present invention discloses a method and a device to reduce horizontal jolt of shipping. The method is as follows: a submerged diving chamber is arranged under the shipping at a depth. The chamber is divided vertically. A vertical symmetry axis of the chamber is the same with the sailing direction of the shipping. The cross section of the submerged diving chamber is in the shape of rectangular, rotundity and so on. When the shipping is jolting horizontally, the submerged diving chamber and the water in the submerged diving chamber are compelled to jolt horizontally to be a hyperbaric chamber weight, which prevents the shipping from jolting. When the shipping is sailing without horizontal jolt, the present invention prevents the shipping from invalid load. When the shipping is sailing with horizontal jolt, the shipping keep stable because of the effective damping of the submerged diving chamber and the water in the submerged diving chamber.

Description

technical field [0001] The invention relates to a method and a device for stabilizing a ship, in particular to a method and a device for reducing lateral pitching of a ship. Background technique [0002] Generally, ships will be bumped by wind and waves, and the magnitude of the bumps depends on the tonnage of the ship and the size of the wind and waves. The turbulence of the ship in the wind and waves will not only cause seasickness of the crew, displacement of cargo, damage to the hull structure, etc., but also hide the danger of shipwreck. In the history of shipping, there are shipwrecks in the world every year in which ships capsize and sink due to violent turbulence in violent winds and waves, causing heavy casualties. Since the width of the ship is smaller than the length, the amplitude and frequency of the ship's lateral pitching are much larger than that of the longitudinal pitching, so the lateral pitching is more harmful to the safety of the ship. At present, the...
