Problems solved by technology

Its disadvantages include additional resistance to the ship, complex devices, high manufacturing and maintenance costs, and more tonnage of the ship (if a hydraulic transmission mechanism is used, its total weight can reach 10% of the ship's displacement). There is also a fatal shortcoming: the fin stabilizers can effectively stabilize only when the ship's speed is high, and the fin stabilizers can hardly stabilize the ship when the ship is at low or zero speed.
The main problem faced by comprehensive anti-rolling is the increase of anti-rolling cost

Embodiment 1

[0058] Such as figure 1 , Figure 8 , Figure 10 , Figure 11 As shown, in the ship anti-rolling device provided by Embodiment 1 of the present invention, the ship anti-rolling device is provided with one or more buffer energy-absorbing mechanisms on both sides of the hull (14). The buffer energy-absorbing mechanism includes a side wall 1 and an elastic member 15. One end (the lower end in the figure) of the side wall 1 is connected to the bilge of the ship through a movable joint 2, and the other end (the upper end in the figure) passes through the The elastic member 15 is connected to the side shell 9 . The side wall 1 rotates around the movable joint 2, one end (the inner end in the figure) of the elastic member 15 is fixedly connected with the side outer plate 9, and the other end (the outer end in the figure) is connected with the side wall 1 connection. Preferably, the elastic member 15 is a helical compression spring.

Embodiment 2

[0067] Such as figure 2 , Figure 5 and Figure 11 As shown, in the ship anti-rolling device provided by Embodiment 2 of the present invention, the ship anti-rolling device is provided with one or more buffer energy-absorbing mechanisms on both sides of the hull (14). The buffer energy-absorbing mechanism includes a side wall 1 and an air bag 12. One end of the side wall 1 (the lower end in the figure) is connected to the bilge of the ship through a movable joint 2. Between the side wall 1 and the side shell 9 Said air bag 12 is arranged between.

[0068] The anti-rolling device can effectively buffer, absorb, and transform the lateral force of waves on one side of the hull 14, reduce the roll of the ship, and keep the ship sailing smoothly.

[0069] An opening 13 is provided on the inner wall of the opposite airbags 12 on both sides of the hull (14), and the openings 13 of the two airbags 12 communicate through a communication tube 27, realizing the communication between ...

Embodiment 3

[0075] Such as Figure 3-12 As shown, in the ship anti-rolling device provided by the third embodiment of the present invention, the ship anti-rolling device is provided with one or more buffer energy-absorbing mechanisms on both sides of the hull (14). The buffer energy-absorbing mechanism includes a side wall 1, an elastic component 15 and an air bag 12. One end of the side wall 1 is connected to the bilge of the ship through a movable joint 2, and the other end is connected to the side shell 9 through the elastic component 15. Connection; the airbag 12 is arranged between the side wall 1 and the side shell 9 .

[0076] The anti-rolling device can effectively buffer, absorb, and convert the lateral force of waves on one side of the hull 14 through the elastic component 15 and the airbag 12, so as to reduce the roll of the ship and keep the ship sailing smoothly.

[0077] A deck extension 7 is provided above the buffer energy-absorbing mechanism, one end (inner end in the fi...

Abstract

The invention relates to the technical field of boats, in particular to a boat swaying buffering device applicable to a large-scale boat. The boat swaying buffering device is characterized in that one or a plurality of buffer energy absorbing mechanisms are respectively arranged at the two sides of a boat body, the buffer energy absorbing mechanisms can effectively buffer, absorb and convert the lateral acting force of waves on one side of the boat body, the transverse swaying of the boat can be reduced, the stable navigation of the boat is maintained, in addition, the deadweight tonnage of the boat can be favorably improved, and the safety of the boat can be improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an anti-rolling device suitable for large ships and capable of keeping the ships sailing smoothly. Background technique [0002] When a ship is navigating at sea, among the six degrees of freedom swaying motions caused by wave force, such as roll, pitch, yaw, sway, surge, and heave, ship roll is the most likely to occur, and the amplitude of the sway is the largest. The impact on ship safety is most serious. Therefore, the most commonly used measure for ship balance is roll stabilization, and the so-called ship anti-roll transposition usually refers to the ship anti-roll device. [0003] The cause of ship rolling: one side of the ship sways to the opposite side at a certain angle under the action of wave force, and the ship leaves the original equilibrium position and rotates around the longitudinal axis of the ship at the same angle; when the wave force stops, due to the stabilit...
