In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Embodiment 1, as shown in fig. 1 to 5, a wave-dissipating device for a ship includes two pin bosses 1 fixedly disposed on two sides of a ship board, each pin boss 1 is pivotally connected to one end of a short connecting plate 2, the other end of each short connecting plate 2 is pivotally connected to one end of a long connecting plate 3 through a first through shaft 8, a second through shaft 4 is pivotally connected to the other ends of the two long connecting plates 3, a floating body 5 is fixedly disposed on the second through shaft 4 between the two long connecting plates 3, the floating body 5 is in a spindle shape with two gradually reduced ends, a plurality of linear grooves 51 are uniformly disposed on a middle surface of the floating body 5, and a plurality of spiral grooves 52 communicated with the linear grooves 51 are uniformly disposed on surfaces near two ends of the floating body 5. Two ends of the beam 6 are respectively fixedly connected with the two long connecting plates 3, and a lifting ring 7 is fixedly arranged on the beam. The beam 6 can fixedly connect the whole wave dissipation device into a whole, so that the whole wave dissipation device is convenient to pull. The length of the short connecting plate 2 is slightly longer than the thickness of the ship board, so that the long connecting plate 3 is suitable for suspending outside the ship board or in the ship cabin, and the length of the long connecting plate 3 is slightly smaller than the height of the ship board, so that the floating body 5 is partially immersed in water or placed on a bottom plate in the ship cabin. When the floating body 5 is placed on the bottom plate in the cabin, people can sit on the floating body, and when the floating body is turned over for 180 degrees and is immersed in water, the direct impact of surge on the ship can be reduced. The wave eliminating principle is that when the surge on the side of the ship is gushed to the ship, the ship firstly touches the floating body 5, and the floating body is provided with a linear groove, so that the surge can drive the floating body 5 to rotate around the second through shaft 4, when the surge on the bow or the stern is gushed to the ship, the two ends of the floating body are provided with spiral grooves, so that the surge can drive the floating body 5 to rotate around the second through shaft 4, and the impact force of the surge on the bow or the stern to the ship is reduced due to the shape of the fusiform. The kinetic energy of the surge is converted into circular motion and potential energy, the impact force on the ship body is reduced, and the jolt of the ship body is reduced, and the jolt is similar to the circle-drawing force-eliminating force in a Tai Chi pushing arm, and four or two sets of jacks are arranged to achieve the aim of resisting the steel.

Embodiment 2 is the same as embodiment 1, except that a bidirectional buffering rotary damper 9 is fixedly arranged on the first through shaft 8 close to the short connecting plate 2, the rotary damper 9 includes a cylinder shaft 91 which is sleeved on the first through shaft 8 and is in clearance fit with the first through shaft, the gear 10 is fixedly arranged at one end of the cylinder shaft 91, a cylinder sleeve 94 is hermetically arranged outside the cylinder shaft 91, an open end of the cylinder sleeve 94 is blocked by a flange 95, the cylinder sleeve 94 is filled with hydraulic oil or air, the flange 95 is fixedly connected with the first through shaft 8, a shifting plate 92 with micropores 93 is fixedly arranged on the cylinder shaft 91 in the cylinder sleeve 94, and an end surface of the shifting plate 92 is in clearance fit with inner walls of the cylinder sleeve 94 and the flange 95 respectively. The long connecting plate 3 is close to the position of the first through shaft 8, an incomplete gear ring 11 is fixedly arranged, and the incomplete gear ring 11 is meshed with the gear 10. First rectangle keyway 13 is seted up to the top surface of key seat 1, when the free end of even board 2 overturns to the outboard the even board 2 of short last set up with second rectangle keyway 21 that rectangle keyway 13 corresponds, rectangular key 14 can insert in first rectangle keyway 13 and the second rectangle keyway 21 with the locking even board 2 of short, prevent even board 2 of short for the rotation of key seat 1. A blind hole 15 is formed at the shaft end of the short connecting plate 2 pivoted with the pin boss 1, one end of the rectangular key 14 is turned 180 degrees and extends to form a tail plug 141, and the tail plug 141 can be inserted into the blind hole 15 to prevent the rectangular key 14 from being knocked down or lost.

Because the surge not only has the impact force to the hull, but also has the characteristic of up-and-down reciprocating fluctuation, the impact force of the surge can drive the long connecting plate to swing clockwise and anticlockwise, the up-and-down fluctuation of the surge can drive the floating body to fluctuate up and down, so as to drive the long connecting plate to swing clockwise and anticlockwise, and the rotary damper adopts bidirectional buffering, so that the large part of kinetic energy of the surge impact force and the up-and-down fluctuation is used for offsetting the resistance of the rotary damper 9, and finally becomes heat to be consumed, thereby further enhancing the wave dissipation effect.

The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; those skilled in the art can make many possible variations or modifications to the invention using the methods and techniques disclosed above, or to modify equivalent embodiments without departing from the scope of the invention. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention.
