A scientific investigation ship with an anti-rolling water tank system

Abstract

The invention discloses a scientific research ship with an rolling stabilizing water compartment system. The scientific research ship is provided with a hull and a cabin, the cabin is internally provided with an rolling stabilizing water compartment system, the rolling stabilizing water compartment system comprises 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 compartment, the water compartment body is internally filled with liquid and comprises left and right adjusting compartments which are arranged in the left and right compartments respectively, a baffle which penetrates through the connecting compartment to divide the connecting compartment into a lower connecting compartment and an upper connecting compartment is arranged on the part between the left and right adjusting compartments, left and right rapid adjusting compartments are formed in the parts between the leftand right adjusting compartments and the outer side walls of the left and right compartments respectively, and rapid adjusting devices and air pressure adjusting devices which are used for controlling the heights of liquid levels of liquid in left and right passive compartments are arranged in the left and right adjusting compartments respectively. The rolling stabilizing water compartment systemhas the advantages that the rolling stabilizing water compartment system can effectively operate within a wider frequency range, and rolling increasing does not take place both in low and high frequency ranges.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a scientific investigation ship with an anti-rolling water tank system. Background technique [0002] The research on roll stabilization in the field of ship and ocean engineering has a history of more than 100 years. During this period, according to statistics, there have been at least 300 types of anti-rolling devices, but only a few methods have been tested by long-term practice. It has been popularized and applied, such as bilge keels, fin stabilizers, and water stabilizer tanks. Among them, water tank stabilizers are a very commonly used anti-roll device. Its advantages are simple equipment, low cost, and effective at any speed. A certain anti-rolling effect has been widely used in various types of boats. The working principle of the anti-rolling water tank is to use the moment generated by the water level difference between the two sides of the anti-rolling water ta...

AI Technical Summary

Problems solved by technology

[0005] (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

[0006] (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

[0007] (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

[0009] (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
