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] like 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] like figure 2 , Figure 5 and Figure 11 As shown, in the ship anti-rolling device provided by the second 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 and an air bag 12. One end (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 side wall 1 and the side shell 9 Said airbags 12 are arranged therebetween.

[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] The opposite air bag 12 inner wall of hull (14) both sides is provided with opening 13, and the described opening 13 of two described air bags 12 is communicated by connecting pipe 27, has realized the communication of opp...

Embodiment 3

[0075] like 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 figur...

Abstract

The invention relates to the technical field of ships, in particular to a ship anti-rolling device suitable for large ships. The anti-rolling device is provided with one or more buffer energy-absorbing mechanisms on both sides of the hull, through which the buffer energy-absorbing mechanism can effectively buffer, absorb, and transform the lateral force of waves on one side of the hull, reducing the transverse force of the ship. Shake, keep the ship sailing smoothly, and help to increase the deadweight tonnage of the ship and improve the safety of the ship.

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 ship anti-rolling device usually refers to the ship anti-rolling 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 stability of the sh...
