Description

Technical Field

[0001] The present invention belongs to the field of wave attenuation, and particularly relates to a floating breakwater capable of effectively attenuating long-period waves. Background Art

[0002] A floating breakwater is usually composed of a box body or a floating raft with a certain draft. The box body or the floating raft is connected to an anchor chain fixed at one end to the seabed and floats on the water surface. Its wave attenuation principle is mainly to use the floating body to prevent the wave from propagating or to break the wave, so as to achieve the purpose of attenuating wave energy.

[0003] Existing floating breakwaters are generally assembled from multiple individual and structurally identical unit modules. The connection structure between each unit module is generally a chain or the like, which makes the stability of each unit module poor after combination.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a floating breakwater that can effectively reduce long-period waves. On both sides of the front end of the floating box, side plates are fixedly connected. Bearing seats are installed through the side plates. A rotating cylinder is rotatably sleeved between the bearing seats on both sides. Inside the rotating cylinder, a bidirectional lead screw with opposite thread directions at both ends is rotatably sleeved through a mounting seat. Threaded rings are provided on the outer sides of the threaded sleeves at both ends of the bidirectional lead screw. A plurality of sliding grooves are circumferentially arranged along the axial direction of the bidirectional lead screw on the outer side of each threaded ring. The sliding grooves are rotatably connected to rotating rods. The outward extending ends of the rotating rods rotatably connected to the same radial direction of the threaded rings at the left and right ends are provided with sliding grooves. Each sliding groove is rotatably connected to a wave-dissipating plate. When the side with the rotating cylinder faces the wave direction and long-period waves impact, they can strike on the wave-dissipating plate, thereby driving the rotating cylinder to rotate, and effectively unloading the long-period waves. Since both ends of the bidirectional lead screw extend outside the two ends of the rotating cylinder and are fixedly connected with limit disks, positioning bolts that can be connected to the rotating cylinder are arranged through the limit disks. At the same time, rotating handles are connected to both limit disks. Therefore, during specific use, the rotating handles can be rotated to drive the limit disks to rotate, thereby driving the bidirectional lead screw to rotate, and adjusting the distance between the threaded rings on both sides, thereby realizing the adjusted rotation of the rotating rods, and driving the wave-dissipating plates to adjust the distance from the axis of the rotating cylinder, so as to facilitate specific adjustment according to different usage situations. When the wave-dissipating plates are far from the rotating cylinder, they can reduce waves with greater potential energy. After the adjustment is completed, the limit disks can be relatively fixed to the rotating cylinder through the positioning bolts. At the same time, when rotating the handle, it is necessary to control the rotating cylinder not to rotate accordingly.

[0026] By fixedly connecting connection rings that can cooperate with the connection rings on the connection seat on both sides of the floating box, the floating box can be installed on the connection seat. At the same time, since the connection rings on the mounting plate are fixedly connected to the mounting plate, and the mounting plate is fixedly connected to the transverse slider, the transverse slider is slidably sleeved on the outside of the cross bar. The vertical sliders fixedly connected to both ends of the cross bar are slidably sleeved on the outside of the vertical bar. A second spring is sleeved on the outside of the cross bar to buffer the transverse sliding of the transverse slider, and a first spring is sleeved on the outside of the vertical bar to buffer the up and down sliding of the cross bar, thereby effectively buffering the floating box and the rotating cylinder indirectly connected thereto after being impacted by long-period waves.

[0027] By fixedly connecting a round rod to the bottom of the floating box, and fixedly connecting discs to both ends of the round rod, both the upper and lower ends of the mutually remote sides of the two discs are also rotatably connected to connecting plates through scroll hinges. A countercurrent plate is fixedly connected between the connecting plates on the same upper and lower sides. A limiting platform is also fixedly connected between each disc and the upper and lower two connecting plates, so that under the action of the scroll hinge, the upper and lower two connecting plates can be limited by the limiting platform respectively. At the same time, two limiting slide rods are fixedly connected to the connecting seat through a connecting plate. The upper and lower two limiting slide rods are respectively in sliding contact with the mutually close side surfaces of the countercurrent plates on the upper and lower sides. In this way, when the floating box is displaced backward after being impacted by waves, the disc will be driven to move backward, and the upper and lower two countercurrent plates will respectively contact the upper and lower limiting slide rods, driving the upper and lower two countercurrent plates to rotate away from each other to open a larger angle, thereby enabling the countercurrent plates to expand to a larger angle to form a greater resistance with the water flow behind them, effectively reducing its own front-back sway. When swaying up and down, the countercurrent plates can also increase the resistance with the water flow, thereby effectively improving the stability. This makes the device have high stability and can effectively reduce long-period waves at the same time.

[0028] The floating breakwater of the present invention includes a floating box 1, a connecting seat 2, a rotating wave dissipation mechanism and a counteracting device. The rotating wave dissipation mechanism is arranged in front of the wave-facing surface of the floating box 1 and is fixedly connected to both side surfaces of the floating box 1 through a connecting structure; two connecting seats 2 are respectively arranged on both sides of the floating box 1 and are connected to the connecting structure. The counteracting device is arranged below the floating box 1 and is fixedly connected to the bottom of the floating box 1 and the connecting seats 2 on both sides; the rotating wave dissipation mechanism includes a wave dissipation plate 11. When impacted by long-period waves, it strikes on the wave dissipation plate, thereby driving the entire rotating wave dissipation mechanism to rotate, realizing effective unloading of the long-period waves. At the same time, the wave dissipation ability of the wave dissipation plate is adjusted by adjusting the relative distance between the wave dissipation plate 11 and the rotating shaft of the rotating wave dissipation mechanism; the connecting seat 2 is used to buffer the floating box 1 and the rotating wave dissipation mechanism in the front-back and up-down directions after being impacted by long-period waves; the counteracting device is used to increase the water flow resistance and reduce the sway of the floating breakwater itself.

[0029] The rotating wave dissipation mechanism further includes a rotating cylinder 5 and a limiting mechanism. The limiting mechanism includes a limiting disc 12, a rotating handle 13 and a positioning bolt 14.

[0030] Please refer to Figures 1-6, the present invention provides a technical solution: a floating breakwater capable of effectively reducing long-period waves, which includes a floating box 1 and a connecting seat 2. On both sides of the floating box 1, side plates 3 are fixedly connected. On one side of the two side plates 3 close to each other, bearing seats 4 are fixedly connected. A rotating cylinder 5 is rotatably connected between the bearing seats 4 on both sides. The rotating cylinder 5 is a cylindrical structure formed by a plurality of rotating plates arranged at circumferential intervals. Inside the rotating cylinder 5, a bidirectional lead screw 8 with coaxial rotation is arranged. An installation seat 7 is fixedly sleeved in the middle area of the bidirectional lead screw 8 inside the rotating cylinder 5. Threaded sleeves are provided at both ends of the outer side of the bidirectional lead screw 8, and threaded rings 9 are arranged. On the outer side of each threaded ring (9), a plurality of rotating rods (10) are circumferentially rotatably connected. The extending ends of the plurality of rotating rods (10) are slidably connected to the sliding grooves (6) on the inner side surfaces of the plurality of rotating plates. On the outer side surface of each rotating plate, a wave-dissipating plate (11) is provided. At the same time, vertical rods 15 are fixedly connected between the two walls at the front and rear ends of the connecting seat 2. A vertical slider 16 is slidably sleeved on the outer side of the vertical rod 15. A cross bar 18 is fixedly connected between the two vertical sliders 16 at the front and rear. A horizontal slider 19 is slidably sleeved on the outer side of the cross bar 18. A mounting plate 21 is fixedly connected to the side of the horizontal slider 19 away from the connecting seat 2. Connecting rings 22 are fixedly connected to the four corners on the side of the mounting plate 21 away from the horizontal slider 19. A counteracting device is also provided at the bottom of the floating box 1.

[0031] The thread directions of the left and right ends of the outer side of the bidirectional lead screw 8 are set to be opposite, and they are respectively threadedly sleeved with the threaded rings 9 on the left and right sides.

[0032] Both ends of the bidirectional lead screw 8 extend outside the two sides of the rotating cylinder 5 and are fixedly connected with limit disks 12. A positioning bolt 14 is threadedly connected through the limit disk 12, and the positioning bolt 14 penetrates the limit disk 12 and is threadedly connected with the rotating cylinder 5. On the side of the two limit disks 12 away from each other on the left and right, a rotating handle 13 is fixedly connected.

[0033] The bearing seat 4 penetrates the side plate 3, and the limit disk 12, the rotating handle 13, and the positioning bolt 14 are all inside the bearing seat 4.

[0034] On both sides of the front end of the floating box 1, side plates 3 are fixedly connected. A bearing seat 4 is installed through the side plate 3. A rotating cylinder 5 is rotatably sleeved between the two bearing seats 4. A bidirectional lead screw 8 with opposite thread directions at both ends is rotatably sleeved in the rotating cylinder through a mounting seat 7. Threaded rings 9 are provided on the outer sides of both ends of the bidirectional lead screw 8. A plurality of rotating rods 10 are circumferentially rotatably connected to the outer side surface of each threaded ring 9. The outward extending ends of the plurality of rotating rods 10 are slidably connected to the sliding grooves on the inner side surfaces of the plurality of rotating plates of the rotating cylinder 5. A wave dissipating plate is connected to the outer side surface of each rotating plate. Thus, when the rotating cylinder 5 faces the wave direction and is impacted by long-period waves, the waves can strike on the wave dissipating plate 11. When the wave dissipating plate 11 rotates stably, its rotating connection will drive the rotating rod 10 to rotate, and then drive the rotating cylinder 5 to rotate simultaneously, so as to effectively unload the long-period waves. Since both ends of the bidirectional lead screw 8 extend outside both ends of the rotating cylinder 5 and are fixedly connected with limit discs 12, positioning bolts 14 that can be connected to the rotating cylinder are provided through the limit discs 12. At the same time, rotating handles 13 are connected to both sides of the limit discs 12. Thus, during specific use, the limit discs 12 can be driven to rotate by manually rotating the rotating handles 13 clockwise or counterclockwise, and then drive the bidirectional lead screw 8 to rotate, reducing or increasing the distance between the two threaded rings 9 on both sides, realizing the adjusted rotation of the rotating rod 10, and thus realizing the adjustment of the axial distance between the wave dissipating plate 11 and the rotating cylinder 5 to facilitate corresponding specific adjustments for different usage situations. For example, when the wave dissipating plate 11 is far from the rotating cylinder 5, it can dissipate waves with greater potential energy. After the adjustment is completed, the limit disc 12 and the rotating cylinder 5 can be relatively fixed through the positioning bolt 14. At the same time, when rotating the handle 13, it is necessary to control that the rotating cylinder 5 does not rotate accordingly.

[0035] Spring one 17 is fixedly connected between the upper and lower ends of the vertical slider 16 and the upper and lower inner walls of the connecting seat 2, and the spring one 17 is sleeved on the outside of the vertical rod 15.

[0036] Spring two 20 is fixedly connected between the front and rear ends of the horizontal slider 19 and the vertical sliders 16 on its front and rear sides, and the spring two 20 is sleeved on the outer side surface of the horizontal slide bar 18.

[0037] Both sides of the connecting seat 2 are provided with connecting rings 22. Among them, the connecting ring 22 on the side of the connecting seat 2 close to the side plate 3 is connected to the side plate 3, so that the floating box 1 is indirectly regarded as being installed on the connecting seat 2. At the same time, since the connecting ring 22 on the mounting plate 21 is fixedly connected to the mounting plate 21, and the mounting plate 21 is fixedly connected to the transverse slider 19. The transverse slider 19 is slidably sleeved on the outside of the cross bar 18. The vertical sliders 16 fixedly connected to both ends of the cross bar 18 are slidably sleeved on the outside of the vertical bar 15. A second spring 20 is sleeved on the outside of the cross bar 18 to buffer the lateral sliding of the transverse slider 19. A first spring 17 is sleeved on the outside of the vertical bar 15 to buffer the up and down sliding of the cross bar 18. Thus, effective buffering can be achieved for the floating box 1 and the rotating cylinder 5 indirectly connected thereto after being impacted by long-period waves.

[0038] Embodiment 2:

[0039] Please refer to Figures 1-6 , the present invention provides a technical solution: The counteracting device includes a support seat 23, a round rod 24, a disc 25, a connecting plate 26 and a countercurrent plate 27. Support seats 23 are fixedly connected to the left and right sides of the lower end of the floating box 1. A round rod 24 is fixedly connected to the bottom of the support seat 23. Discs 25 are fixedly connected to both ends of the round rod 24. Connecting plates 26 are rotatably connected to the upper and lower ends of the mutually remote sides of the two discs 25 through scroll hinges. The mutually remote ends of the left and right two connecting plates 26 on the same upper and lower side are commonly fixedly connected to a countercurrent plate 27. Connecting plates 29 are fixedly connected to the left and right sides of the lower end surface of each connecting seat 2. Limit slide rods 30 are fixedly connected to the upper and lower ends of the mutually close sides of the left and right connecting plates 29. The mutually remote sides of the upper and lower limit slide rods 30 are respectively in sliding contact with the mutually close sides of the upper and lower countercurrent plates 27.

[0040] Limit platforms 28 are fixedly connected to the mutually remote sides of the left and right discs 25. The upper and lower ends of the limit platforms 28 are respectively in inclined contact with the mutually close sides of the upper and lower connecting plates 26, so that a certain angle is initially formed between the two countercurrent plates.

[0041] A support base 23 connected to the bottom of the floating box 1 is fixedly connected to a round rod 24, and both ends of the round rod 24 are fixedly connected to discs 25. Both the upper and lower ends of the mutually remote sides of the two discs 25 are also rotatably connected to connecting plates 26 through scroll hinges, and a countercurrent plate 27 is fixedly connected between the connecting plates 26 on the same upper and lower sides. Each disc 25 is also fixedly connected with a limiting platform 28 between the upper and lower two connecting plates 26, so that under the action of the scroll hinge, the upper and lower two connecting plates 26 can be respectively limited by the limiting platform 28, so that a certain angle is inherently formed between the two countercurrent plates and they will not collide with each other. Especially when the device is subjected to wave force, the rotating shafts connected by the upper and lower connecting plates rotate counterclockwise and clockwise respectively, thereby driving the countercurrent plates to rotate upward and downward, increasing the angle between them. At the same time, two upper and lower limiting slide bars 30 are fixedly connected to a connecting plate 29 connected to the connecting seat 2, and the upper and lower two limiting slide bars 30 are respectively in sliding contact with the mutually close sides of the upper and lower countercurrent plates 27. In this way, when the floating box 1 is displaced backward after being impacted by waves, the disc 25 will be driven to move backward, so that the upper and lower two countercurrent plates 27 respectively abut against the upper and lower limiting slide bars 30, driving the upper and lower two countercurrent plates 27 to rotate away from each other to open a larger angle, and further enabling the countercurrent plate 27 to unfold a larger angle to form a greater resistance with the water flow behind it, effectively reducing its front-back shaking. When shaking up and down, the countercurrent plate 27 can also increase the resistance with the water flow, thereby effectively improving the stability.
