Anti-rollover device for ship and wing plate retracting and spreading device for anti-rollover device

Abstract

The invention discloses an anti-rollover device for a ship and a wing plate retracting and spreading device for the anti-rollover device. The anti-rollover device for the ship comprises a ship body, wherein wing plates are arranged on two sides of the ship body respectively and movably connected with the ship body. Under the conditions of stormy waves, or ship instability and the like, the wing plates can be spread, and left-and-right bumping and shaking and rollover of the ship body are effectively avoided under the buoyancy action of the wing plates. The anti-rollover device for the ship can be equipped with the wing plate retracting and spreading device, by means of the wing plate retracting and spreading device, retraction, spread and lock of the wing plates can be realized, the operation is convenient and fast, and safety and reliability are achieved.

Description

technical field

[0001] The invention relates to the technical field of ships, in particular to a ship anti-rollover device and a flap retractable device used for the anti-rollover device. Background technique

[0002] With the progress of social civilization, the safety of ship navigation has been paid more and more attention by the society. However, the current shipping and tourism industries focus more on the research on navigation operation technology and rescue technology after accidents, but neglect the research on hull structure. The traditional hull structure is generally narrow at the front and wide at the rear, with a V-shaped front and a smooth transition to the middle and rear. The advantage of this structure is that the sailing resistance is small, the speed is fast, and the power consumption is small. However, its anti-rollover ability is poor, and the stability of the hull can only be guaranteed by grasping the center of gravity of the load. When encounterin...

Examples

Embodiment 1

[0033] Such as figure 1 , figure 2 As shown, the ship anti-rollover device of the present invention includes a hull 1, and wing plates 2 are respectively arranged on both sides of the hull 1. Specifically, a support 3 can be respectively arranged on both sides of the hull, and the wing plates 2 can be rectangular or trapezoidal. structure, one end of which is connected to the support 3 through a rotatable shaft, and the wing plate 2 can be attached to the hull 1 by rotation, and can also be opened to an approximately T-shaped position with the hull 1 during use. The wing plate 2 can be provided with a locking mechanism, and the locking structure can be equipped with a fork-shaped locking piece 4 consisting of an upper end push-pull rod 4-2 and a lower end two pins 4-1 on a base plate 5, and the two pins 4-1 are respectively It is located at the front and back sides of the wing plate 2 when it is opened, and is connected with the support 3 and can slide freely. The wing plat...

Embodiment 2

[0036] Referring to 3, as a further improvement of the technical solution of the first embodiment, a groove 6 can be respectively provided on both sides of the hull 2 ​​for storing the wing plate 2 . The wing plate 2 can be connected with the rotating shaft at the front end of the groove 6. When the ship is running normally, the wing plate 2 can be embedded in the groove 6, so as to avoid the resistance of the wing plate 2 from being exposed to the ship, and also prevent the water flow from affecting the wing plate. 2 washout, prolong its service life.

Embodiment 3

[0038] see Figure 4 , Figure 5 , as a further improvement, the front side of the wing 2a is integrally provided with an arc-shaped seesaw 2a-1, so that when the ship is running, the water waves will lift the wing 2a-1, which can better prevent the hull from 1 rollover.
