Problems solved by technology

In addition, long waves or swells during the voyage also affect the bow movement. The waves in front of the bow act on the bow by attacking the bow, causing a large heave and sway of the hull, resulting in a serious decrease in the comfort of passengers. There are also limitations to the use of

Embodiment 1

[0026] refer to figure 2 , a ship anti-rolling method, which includes the steps of setting an additional device 5 with a hydrofoil 4 at the bow 1, and adjusting the additional device 5 to control the lowering, fixing and lifting of the hydrofoil 4. In the sailing direction of the ship, the bow limit wave is formed on the still water surface 3 or long waves and swells 2 are encountered. By setting the additional device 5 with the hydrofoil 4 at the bow 1, the hydrofoil 4 is lowered by the additional device 5 when the ship is running at high speed. , the lift generated by the hydrofoil 4 can lift the bow 1, thereby reducing the contact area between the hull and the water body, and greatly reducing the force of the water body directly hitting the hull. At the same time, when the hull is swaying, the hydrofoil 4 can also increase the contact area between the ship and the water , increase the resistance moment, thereby reducing the swaying of the hull, the ship can maintain high-s...

Embodiment 2

[0030] refer to Figure 6-8 , is another ship anti-rolling device, including hydrofoils arranged on the bow 1, additional devices to realize the lifting, lowering and fixing of the hydrofoils, the additional devices include hydraulic devices 6 arranged on both sides of the bow 1 and the hydraulic devices 6 drives the first hydraulic column 7 and the second hydraulic column 8, and the hydrofoil 4 is arranged at the bottom of the second hydraulic column 8, and a shock absorbing device 9 is provided between the first hydraulic column 7 and the bow 1. A steel rope 11 with one end connected to the wire reel 12 is arranged inside the first hydraulic column 7 , and the other end of the steel cable 11 is connected to the second hydraulic column 8 . Hydrofoil 4 is a split-type hydrofoil with a low middle part and high sides.

[0031] When the ship is running at high speed, the hydraulic device 6 drives the first hydraulic column 7 and the second hydraulic column 8 to move downward, so...

Abstract

The invention discloses a ship stabilization method and a ship stabilization device. The ship stabilization method comprises the steps of arranging an additional device provided with a hydrofoil on a prow, adjusting the additional device to control the hydrofoil to be put down, and fixing and lifting. The ship stabilization method and the ship stabilization device have the advantages of simple structure and convenience for setting; relatively large influences on an existing ship body structure are not caused; and the swinging of the ship body can also be effectively alleviated when the ship is operated at a high speed, and the comfort of traveling by ship is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method and a device for improving the comfort of a ship. Background technique [0002] With the continuous optimization of the ship type and the improvement of the power plant, the sailing speed of the ship is also increasing. However, ships sailing at high speeds are easily disturbed by waves, including ship waves that contain shear waves and scattered waves, especially during high-speed travel, such as figure 1 As shown in , the scattered waves in the ship's traveling waves gradually disappear, and the shear waves develop significantly. At this time, the bow limit wave or long wave and swell wave 2 in the form of shear waves higher than the still water surface 3 are formed in front of the bow 1, and act on the bow 1. In addition, long waves or swells during the voyage also affect the bow movement. The waves in front of the bow act on the bow by attacking the bow, causing a lar...
