Description
Technical Field
The invention relates to the technical field of ship equipment, in particular to a rapid anti-rolling device based on a passive anti-rolling tank.
Background
When a ship sails and works on the sea, due to the action of disturbance of sea environments such as sea waves, sea winds, sea currents and the like, swinging motion is inevitably generated, violent swinging not only influences the sailing of the ship, but also threatens the safety of the ship, the comfort of people in the sailing process is greatly reduced, adverse influence is brought to equipment on the ship, and unsafe factors are brought to goods and personnel on the ship. The periodic reciprocating motion of a vessel around a certain equilibrium position while sailing on standing water or waves is called heave of the vessel. Swaying of a vessel includes rolling, pitching, yawing, pitching, rolling and heaving (heaving). Among them, the most significant effects on ships are roll, pitch and heave, which can be generally characterized by amplitude and period (or frequency). The ship sailing is affected most by rolling, pitching and heaving, the rolling is easy to happen, the swaying amplitude is also the largest, and the safety of the ship is affected seriously. The swinging of the ship causes the increase of navigation resistance, the reduction of propeller efficiency and the influence on ship speed, and influences the use of weapons and technical equipment, thereby causing personnel fatigue and seasickness and deteriorating the navigation performance of the naval vessel.
The effect of the swaying motion on the ship is disadvantageous, mainly expressed in the following aspects:
(1) influence on ship performance: violent rolling can cause the ship to lose stability and overturn, and pitching and heaving can cause the propeller to fly, so that the navigational speed is reduced. The violent shaking increases the ship resistance; the propeller condition worsens, bringing difficulty to the vessel handling.
(2) Effects on ship structure and equipment: the bottom beating phenomenon can occur when the ship shakes, so that additional stress is generated in the ship body components, and certain components are damaged. The rocking can cause surging, damaging equipment and buildings on the deck.
(3) The ship swaying can affect the normal work of mechanical equipment, instruments and meters; meanwhile, causing seasickness of crew and passengers, and deteriorating working and living environments; but also causes the cargo to move or collapse causing damage to the cargo.
(4) During transportation by a barge fleet, the swaying amplitude and the time of each barge in stormy waves are inconsistent.
(5) And the ship sways to enable scientific investigation equipment to exceed the working environment, so that the acquisition of scientific investigation data is influenced.
The swaying of the ship cannot be completely avoided, the ship is most likely to roll on the sea and has the largest swaying amplitude, and the use and safety of the ship and the life and work of crew are seriously affected, so the ship rolling is firstly researched in the wave resistance of the ship. Although the phenomenon of ship body rolling cannot be avoided, the wave encountering angle can be reduced, the shaking amplitude can be reduced, the shaking period can be properly increased, and the shaking amplitude can be reduced by adopting the stabilizing device.
For this reason, corresponding anti-rolling devices must be installed on military ships, business ships and scientific ships, and the installation of anti-rolling tank devices on ships can overcome the problems, so that the controllable passive anti-rolling tank for ships forms a new ship equipment manufacturing market. The controllable passive anti-rolling water tank has three modes of air valve control, water valve control and combined control, and its basic anti-rolling principle is to regulate the self-rolling period of water tank to make it match with the inherent rolling period of ship, because the maximum anti-rolling action can be played only when the inherent rolling period of ship has large variation range.
