Problems solved by technology
Among them, the fin stabilizer technology comes from the ship stabilizer design technology, which is mainly aimed at the control of ship roll, but in the case of low-speed flow, a fin stabilizer with a larger fin area is required; the dynamic vibration absorber can effectively control the low frequency of the ship. However, for low-frequency and large-scale motion, it is necessary to configure a large-mass shock absorber, which increases the cost of anti-rolling and raises the center of mass of the ship, which is likely to affect the stability of the ship structure; The control effect of shaking and other rotary motions is not obvious

Embodiment Construction
[0020] The technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only some, not all, embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0021] The present invention proposes an intelligent anti-rolling system for ships, the anti-rolling system includes at least one anti-rolling unit, such as figure 1 As shown, the anti-rolling unit includes a pivotable anti-rolling plate located at the bottom of the hull, a damping cavity, an air guide line 5, and a buffer air storage chamber 6. The anti-rolling plate includes the left side of the hull 1 and The right side anti-rolling plate 2 of the hull, one end of the two anti-rol...

The invention relates to an intelligent stabilization system for a ship. The stabilization system comprises at least one stabilization unit, each stabilization unit comprises stabilization plates located on a left side and a right side of a bottom of a ship body and a damping cavity. Through mutual extrusion and pushing effects between the stabilization plates and a compressed gas in the damping cavity, when one side of the ship body is impacted, the stabilization plate on the side can extrude the compressed gas in the damping cavity on the side so that an impact force of a wave body can be buffered to absorb impact energy; meanwhile, buoyancy borne by the ship body on the side is also reduced, then the compressed gas is exhausted to the damping cavity in the other side and further pushesthe stabilization plate on the other side to rotate outwards, the other side of the ship body can bear the damping effect of the stabilization plate on the other side, and meanwhile the buoyancy borneby the ship body on the other side is also increased; and through a bidirectional swing damping effect and buoyancy compensation adjustment, the influence of transverse swing on the ship body can begreatly reduced.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to an intelligent anti-rolling system for ships. Background technique [0002] Ships will be affected by factors such as waves, winds and currents when navigating and working on seas, lakes or rivers. Especially at sea, due to frequent strong winds and waves, ships are prone to sway, and severe sway will seriously affect The safe navigation of the ship, the comfort of the ship and the normal operation of various mechanical equipment and equipment on the ship. At the same time, when the ship is sailing, the constant changes of the crests and troughs of the waves will directly collide with the bottom of the ship, especially when sailing in strong winds and waves, the bottom of the ship is prone to slamming, which will cause high-frequency vibration of the ship, and at the same time, the slamming will cause the bottom of the ship The local strength and overall strength of the ship also ...
