Problems solved by technology

The construction cost of the flexible capsule floating breakwater is low, but due to its high flexibility, the effect of wave suppression on long-period waves is not obvious, and the oxidation resistance and structural strength of its materials cannot meet the requirements for year-round application, so it is mainly used for Temporary sea state protection equipment for offshore construction operations is not suitable for long-term fixed deployment in a certain sea area

Embodiment 1

[0032] Such as Figure 1~4 , Figure 6 As shown, the anti-wave floating body unit 1 designed in this embodiment includes an inner cylinder 2 and an outer cylinder 3 . in:

[0033] The inner cylinder 2 adopts a watertight steel cylinder, and a cavity partition plate 2.4 is arranged inside it. Cavity dividing plate 2.4 is parallel to the axial direction of inner cylinder 2, and the inner cavity of inner cylinder 2 is divided into two independent and respectively airtight parts of buoyancy aid cavity 2.1 and density chamber 2.3. The function of the buoyancy aid cavity 2.1 is to provide buoyancy for the main body of the breakwater to ensure that the structure of the breakwater is stable at the specified waterline. The function of the density chamber 2.3 is to lower the center of gravity of the breakwater. The density chamber 2.3 is completely filled with water, and there is no sloshing problem of the free liquid surface , this design method is similar to the tumbler principle, ...

Embodiment 2

[0039] Such as Figure 5 As shown, the basic structure of the rotary turbulent breakwater designed in this embodiment is the same as that of Embodiment 1, the difference is that a spring bearing device 7 is used between the inner cylinder 2 and the outer cylinder 3 to replace the damping energy dissipation device 5 and bearing 6.

[0040] The spring bearing device 7 includes a third inner ring 7.1, a third outer ring 7.2, and four sets of springs 8 and four sets of rollers 11 surrounding the annular space between the two. As a simplified structure, the spring bearing device 7 uses the inner cylinder 2 as its third inner ring 7.1, and the outer cylinder 3 as its third outer ring 7.2. Each group of springs 8 includes a plurality of springs 8 arranged side by side along the circumference of the inner cylinder 2 and perpendicular to the axial direction of the inner cylinder 2, and each group of rollers 11 includes a plurality of rollers 11 arranged side by side along the axial di...

Embodiment 3

[0042] Such as Figure 7 As shown, the rotating spoiler breakwater designed in this embodiment includes a plurality of anti-wave floating body units 1 ( Figure 7 Two are used as an example, and more can be used in practice), and each anti-wave floating body unit 1 adopts the anti-wave floating body unit 1 in Embodiment 1 or 2. During actual construction work, each anti-wave floating body unit 1 forming the breakwater is towed from the wharf to a designated sea area, each anti-wave floating body unit 1 is independent of each other, connected with cables 12 and anchors 13, and anchored in front of the waves 13 can be fixed.

Abstract

The invention discloses a rotary turbulent flow breakwater and an anti-wave floating body unit thereof. The anti-wave floating body unit comprises an inner cylinder and an outer cylinder. A closed floating assisting cavity is formed in the inner cylinder to provide proper buoyancy. The outer cylinder is arranged outside the inner cylinder in a sleeving manner and can rotate by taking the inner cylinder as a shaft. A plurality of spoilers are arranged on the outer side of the outer cylinder in a surrounding mode, and a cable tying piece used for being connected with a cable is arranged on the inner cylinder. The rotary turbulent flow breakwater comprises at least one anti-wave floating body unit, and each anti-wave floating body unit can be arranged in an independent anti-wave or combined anti-wave mode. The spoiler drives the outer cylinder to rotate relative to the inner cylinder under the action of waves, wave energy is consumed in the rotating process, combination of mechanical motion active wave absorption and spoiler structure passive wave absorption is achieved, and the wave absorption effect is greatly improved.

Description

technical field [0001] The invention relates to a breakwater, in particular to a rotating turbulent breakwater and a breakwater floating body unit thereof. Background technique [0002] With the rapid development of my country's marine engineering, there are more and more supporting facilities such as coastal tourism and marine ranch. However, due to the complex environment of sea waves, in order to ensure the safety of people active in the sea and promote the maximum development of coastal related industries, breakwaters are used It is of great significance to resist waves and reduce coastal sea conditions. [0003] The current forms of deep sea floating breakwaters are mainly divided into two categories: flexible capsule floating breakwaters and rigid floating box type breakwaters. The construction cost of the flexible capsule type floating breakwater is low, but due to its high flexibility, the effect of wave suppression on long-period waves is not obvious, and the oxidat...
