Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a ship roll-damping water tank structure. Background Technology

[0002] Ships experience rolling motion during navigation, which affects their stability and comfort. Currently, the main anti-roll devices include: (1) Bulge keel: protrudes from the bottom of the ship, increasing the ship's resistance in still water; the roll reduction effect depends on the sea conditions and is only applicable to short-period waves, with poor effect on long-period waves or irregular waves; it has high requirements for the hull shape and needs to be arranged strictly along the bilge curve.

[0003] (2) Anti-roll fins: The anti-roll effect is limited by sea conditions and speed, and is only effective at medium and high speeds and in specific waves. The scope of application is limited, mainly applicable to small fishing boats and near-shore transport vessels. They increase sailing resistance, are complex to design, difficult to install, and costly. Improper placement can affect the efficiency of the propeller and rudder.

[0004] Existing technologies suffer from limited anti-sway effects, narrow applicability, high costs, and complex installation. There is an urgent need for an anti-sway device that is simple in structure, low in cost, and effective. Summary of the Invention

When the adjustable valve is closed, the left and right compartments form a small waterline surface tank. When the adjustable valve is open, the left and right compartments form a U-shaped pipe structure through the pipe below. The anti-roll tank is also equipped with two side backflow baffles. The two side backflow baffles are respectively located in front of and behind the tank wall. One side backflow baffle is located on the left side wall of the anti-roll tank, and the other side backflow baffle is located on the right side wall of the anti-roll tank. The front and rear walls of the water tank wall are symmetrically provided with multiple reinforcing structures; the water tank wall is provided with multiple vent holes.

[0007] A ship roll reduction tank structure also includes an intelligent control system: a water level sensor and a pressure sensor are installed inside the roll reduction tank, which are linked with an adjustable valve to automatically adjust the valve opening according to the ship's roll state, thereby optimizing the roll reduction effect under different sea conditions.

[0008] A ship roll-damping water tank structure also includes an anti-vortex guide plate: an anti-vortex guide plate is installed inside the pipe below the water tank wall to reduce water vortex, reduce energy loss, and improve roll-damping efficiency.

[0009] A ship anti-roll tank structure is provided, wherein the inner wall of the anti-roll tank is coated with an anti-corrosion coating and the connection parts of each component are sealed to prevent seawater corrosion and leakage.

[0011] (2) Simple structure and low cost: Compared to anti-roll fins, it has a simpler structure and significantly lower manufacturing costs; Installation is convenient and does not require large-scale modifications to the hull structure.

[0012] (3) Wide range of applications: Suitable for vessels of all sizes, from small fishing boats to large cargo ships; It is not limited by speed and can effectively reduce roll at both low and high speeds.

[0013] (4) Energy saving and environmental protection: Without increasing navigation resistance, it can even improve navigation efficiency by optimizing the ship's buoyancy; With no external moving parts, maintenance needs and failure rates are reduced.

[0014] (5) Intelligent control: Sensors are linked with valves to achieve automatic adjustment, reducing manual intervention; It can automatically adjust the water tank configuration according to the ship's load status to maintain the best roll reduction effect. Attached Figure Description

[0023] The water tank wall panel 2 is provided with sufficient ventilation holes 4 to avoid insufficient ventilation leading to uncontrollable water flow.

[0024] In this embodiment, an intelligent control system is also provided: A water level sensor and a pressure sensor are installed inside the anti-roll tank 1, which are linked with the adjustable valve 6 to automatically adjust the valve opening according to the ship's roll state, thereby optimizing the anti-roll effect under different sea conditions.

[0029] Working principle: This invention designs a roll-damping water tank structure, separated by a wall panel. An adjustable valve is installed in the wall panel, creating a U-shaped water tank configuration between the left and right compartments. When the valve is closed, small waterline surface water tanks are formed on both sides. Pipes and adjustable valves are installed below the wall panel, forming a U-shaped pipe structure when the valve is open. This invention also incorporates a wall panel structure with a central backflow barrier to improve water flow direction, ensuring it flows according to the designed direction and frequency, and allowing for control of the initial flow velocity. The wall panel is reinforced to withstand roll-damping torque. Sufficient ventilation holes are provided in the wall panel to prevent uncontrollable water flow due to insufficient ventilation.

This invention also designs the specifications of the anti-roll tank, utilizing its structural design and other parameters to influence the water flow oscillation period, ensuring the water flow oscillation frequency matches the ship's natural rolling frequency, thereby maximizing the anti-roll effect. Adjustable valves are used to regulate the water flow, optimizing the anti-roll effect under different sea conditions. Furthermore, this invention incorporates the anti-roll tank into the ship's center of gravity adjustment calculations, resulting in better buoyancy and improved navigation efficiency.
