A scientific investigation ship with an intelligent anti-rolling device

Abstract

The invention discloses a scientific research ship with an intelligent rolling stabilizing device. The scientific research ship comprises a hull and a cabin, the intelligent rolling stabilizing devicecomprises a water compartment body which is composed of a left compartment, a right compartment and a connecting compartment which is communicated with the left and right compartments, the water compartment body is filled with liquid which completely fills the compartment, spreads upwards along the left and right compartments and can generate periodic gravity moment, an adjusting mechanism, a water amount controlling mechanism which is used for controlling the liquid increasing or reducing amount in the water compartment body when the liquid level of the liquid in the left compartment is controlled to be increased or reduced by the adjusting mechanism, an air pressure adjusting device which is used for replenishing the liquid to the left compartment on the other side passing through the connecting compartment when the liquid level in the right compartment is reduced are arranged in the left compartment, and the hull is internally provided with a rotary controlling device which is usedfor controlling the transverse rolling of the water compartment body. The scientific research ship with the intelligent rolling stabilizing device has the advantages that automatic controlling is achieved by using a detecting signal, rolling increasing does not take place within high and low frequency ranges, and the rolling stabilizing speed is increased.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a scientific investigation ship with an intelligent anti-rolling device. Background technique [0002] When a ship is sailing and working at sea, due to the disturbance of the ocean environment such as waves, sea winds and currents, it will inevitably produce swaying movements. The severe swaying not only affects the navigation of the ship, but also greatly reduces people's safety during the voyage. comfort, and have 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 the ship includes roll, pitch, yaw, surge, sway and heave (heave). Among them, rolling, pitching and heaving have a greater impact on ships, and the three can usually be characterized by swing a...

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

[0012] The control scheme of the passive anti-rolling water tank in the above-mentioned patent solves the problem that the traditional passive anti-rolling water tank can only rely on the energy generated by the ship's rolling motion itself to make the water in the water tank flow and generate torque to offset the ship's rolling motion. and greatly increased the anti-rolling frequency range, but there are also some disadvantages at the same time. For example, the method of completely controlling the signal is not only complicated in structure, but also has a high failure rate and high equipment maintenance costs; The rolling water tank cannot achieve the purpose of rapid anti-rolling, that is to say, the anti-rolling water tank in the prior art cannot achieve the speed at which the remaining roll angle tends to zero, which has become the current research process for overcoming the ship's rolling problem. a major obstacle
