Intelligent stabilized water tank system for ship

Abstract

The invention discloses an intelligent stabilized water tank system for a ship. The intelligent stabilized water tank system comprises a water tank body. The water tank body is composed of a left cabin, a right cabin and a connecting cabin for making the left cabin communicated with the right cabin. Liquid which is fully injected in the connecting cabin, upwards spreads along the left cabin and the right cabin and can generate the periodical gravity torque is injected in the water tank body. The intelligent stabilized water tank system further comprises a left adjusting cabin and a right adjusting cabin arranged in the left cabin and the right cabin respectively. A partition plate which penetrates through the connecting cabin and divides the connecting cabin into a lower connecting cabin body and an upper connecting cabin body is arranged between the left adjusting cabin and the right adjusting cabin. A left side rapid adjusting cabin and a right side rapid adjusting cabin are formed between the left adjusting cabin and the outer side wall of the left cabin and between the right adjusting cabin and the outer side wall of the right cabin respectively. Rapid adjusting devices are arranged in the left adjusting cabin and the right adjusting cabin respectively. The intelligent stabilized water tank system can effectively work within the wide frequency range, and the shaking increasing phenomenon cannot happen in the low-frequency and high-frequency ranges.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to an intelligent anti-rolling water tank system for ships. Background technique [0002] When a ship is navigating and working at sea, due to the disturbance of the marine environment such as waves, sea winds and currents, it will inevitably produce swaying motions. Severe swaying not only affects the navigation of the ship, but also endangers the safety of the ship in severe cases. It will also greatly reduce the comfort of people during the voyage, and bring adverse effects on the equipment on the ship, and bring unsafe factors to the cargo and personnel on board. The periodical reciprocating motion of a ship around a certain equilibrium position when navigating on still water or waves is called ship swaying. The sway of a ship includes roll, pitch, bow, surge, sway and heave (heave). Among them, rolling, pitching and heaving have a greater impact on ships, and the three...

AI Technical Summary

Problems solved by technology

[0004] (1) Impact on ship performance: severe rolling may cause the ship to lose stability and capsize, pitching and heaving will cause the propeller to fly, resulting in a decrease in speed

Severe swaying increases the resistance of the ship; the condition of the propeller deteriorates, making it difficult to maneuver the ship

[0005] (2) The impact on ship structure and equipment: when the ship sways, the bottoming phenomenon will occur, which will cause additional stress in the hull components and damage some components

Swaying can cause waves on deck and damage equipment and structures on deck

[0006] (3) The swaying of the ship will affect the normal work of mechanical equipment, instruments and meters; at the same time, it will cause seasickness of the crew and passengers, and deteriorate the working and living environment; it will also cause cargo movement or collapse and damage to cargo

[0008] (5) The swaying of the ship will cause the scientific research equipment to exceed the working environment and affect the collection of scientific research data

The bilge keel has an anti-rolling effect at various speeds, and the anti-rolling effect is the most obvious at zero speed. However, as the speed increases, the damping of the hull itself increases, and the damping produced by the bilge keel accounts for a large proportion of the total damping. The relative ratio decreases, and the anti-rolling effect also decreases
