Detailed Description
The invention will be better explained by the following detailed description of the embodiments with reference to the drawings.
Example 1
The invention provides a deep draft floating breakwater, the total length of which is not a definite value, and the total length of the breakwater is assumed to be L.
The whole breakwater comprises a buoyancy tank main body, a wing plate 3 and an anchoring device, wherein the anchoring device comprises an anchor chain 4 and an anchor weight 5, the anchoring device is fixedly connected to the buoyancy tank main body and plays a role in positioning the breakwater, and the motion response amplitude of the breakwater in the working process is reduced. The buoyancy tank main body comprises a rectangular buoyancy tank 1 and a convex block 2, the convex block 2 is arranged above the rectangular buoyancy tank 1, wherein the width of the rectangular buoyancy tank 1 is not smaller than that of the convex block 2, in the invention, the solid structure of the buoyancy tank main body is of a convex structure, the rectangular buoyancy tank 1 is positioned at the lower part of the water surface, and the convex block 2 is positioned outside the water surface.
According to the illustration of fig. 1 and 2, the inside of the rectangular buoyancy tank 1 is a hollow structure, the upper part is provided with 2 openings 6 which are respectively arranged at the left side and the right side of the protruding block 2, and the openings can be used for injecting water into the inside of the rectangular buoyancy tank 1 and discharging water, so that the dead weight of the rectangular buoyancy tank 1 is changed, the draft of the buoyancy tank main body is adjusted, when incident waves enter the water of the breakwater, liquid in the buoyancy tank can shake, so that a resistance force is generated to prevent the motion of the floating body, the motion amplitude of the breakwater is reduced, the radiation wave induced by the motion is weakened, and the wave eliminating effect can be remarkably improved.
In general, the deeper the draft of the buoyancy tank in the floating breakwater, the better the wave-dissipating effect of the breakwater, but the deeper the draft is, and after the breakwater exceeds a certain draft, the wave will cross the breakwater, so that the wave-dissipating effect of the whole breakwater is weakened, and the bump 2 enhances the wave-dissipating effect of the whole breakwater on the basis of the wave-dissipating of the rectangular buoyancy tank 1 with a certain draft.
The whole bump 2 is positioned outside the water surface, the bump 2 which is completely exposed out of the water surface reflects the injected wave from the far place, and the reflected wave not only loses part of wave energy, but also forms vortex by mutual friction between the reflected wave and the re-injected wave water body, so that the regular particle motion in the original injected wave is destroyed, and the original injected wave is converted into disordered turbulence.
The bump 2 consumes wave energy in the wave by reflection, further blocks energy transfer of the wave, and if larger energy still exists in the wave, the wave energy in the wave can be consumed again after passing over the bump 2 and the wave surmounting phenomenon occurs.
The wave is transmitted by the distance, and the rectangle buoyancy tank 1 reflects the wave, consumes the partial wave energy of wave, when passing through pterygoid lamina 3 top, the wave takes place to break after contacting with pterygoid lamina 3, consumes a large amount of energy, and the lug 2 that is located the surface of water outside is followed to the subsequent bump 2 that hits, and lug 2 stops the wave, has increased the reflection of wave, and the wave forms the vortex before lug 2, has consumed wave energy, still contains great energy in the wave at this moment, and then the wave can cross lug 2 later, takes place to cross the wave, and wave energy will be consumed once more, finally reaches ideal unrestrained effect of eliminating.
For a floating breakwater, increasing the relative width of the floating breakwater is an important way for improving the wave-dissipating effect of the floating breakwater, and the relative width formula is as follows: b (B) L =B/L w Wherein B is L Is of relative width, B is the overall width of the breakwater, L w Is the wavelength of the wave.
According to the invention, the relative width of the floating breakwater is increased by arranging the wing plates 3, the wing plates 3 are arranged on the upper part of the rectangular buoyancy tank 1 and symmetrically distributed on the wave facing side and the wave back side of the rectangular buoyancy tank 1, wherein the side end surfaces of the wing plates 3 are fixedly connected with the side end surfaces of the rectangular buoyancy tank 1, the upper end surfaces of the wing plates 3 are flush with the upper end surfaces of the rectangular buoyancy tank 1, and the upper end surfaces of the wing plates 3 and the upper end surfaces of the rectangular buoyancy tank 1 are flush with the horizontal plane.
Preferably, as shown in fig. 3, the width of the wing plate 3 from the side end face of the rectangular buoyancy tank 1 to the side end face of the wing plate 3 is B1, wherein b1= (0.2-0.5) ·b, B is the total width of the breakwater, and the total width is the sum of the widths of the rectangular buoyancy tank 1 and the wing plates 3 on both sides;
the outwards extending wing plates 3 increase the wave eliminating distance of the breakwater on the basis of increasing the width of the breakwater, the wave eliminating effect of the breakwater is enhanced by improving the wave energy reduction of long-period waves, and as the wing plates 3 are kept at the position flush with the horizontal plane of the still water level at any time, when waves are incident on the wave-facing side of the breakwater from open sea, the waves firstly contact with the wing plates 3, the motion state of water particles in the waves is changed, the incident waves are broken, and a large amount of wave energy is consumed.
In the practical application process of the floating breakwater, due to certain factors such as nonresistible natural environment factors and the like, when the water level of the breakwater changes, and then the upper end face of the wing plate 3 is not level with the static water level, the opening 6 can be used for adjusting the height of the internal water level of the underwater rectangular buoyancy tank 1, and the dead weight of the rectangular buoyancy tank 1 is controlled in modes such as injection, water drainage and the like, so that the upper end face of the wing plate 3 is kept level with the water surface again, and the design requirement is met.
At sea wave wavelength L w In the case of uncertainty, although the wave-dissipating effect of the breakwater can be improved by increasing the structural width B of the breakwater, the tension applied to the anchor chain 4 connected with the buoyancy tank is increased along with the increase of the structural width of the breakwater, and the safety of the entire breakwater is severely affectedAnd (5) sounding.
Because the wing plates 3 are respectively arranged on the wave-facing side and the wave-back side of the buoyancy tank, the motion response amplitude of the buoyancy tank main body in the heave and roll motion process is reduced, the tensile force of the anchor chain 4 on the rectangular buoyancy tank 1 is not increased, but the tensile force is decomposed along the wing plate direction, and therefore the safety and stability of the breakwater are improved.
Preferably, the thickness of the wing plate 3 is not a definite value, in the present invention, the height of the wing plate 3 is assumed to be H, which is the height from the bottom surface to the top of the wing plate 3, wherein h= (0.04-0.1) ·h Draft water ,H Draft water The draft is designed for the buoyancy tank;
the breakwater of the invention adjusts the dead weight of the rectangular buoyancy tank 1 in a water injection and drainage mode, and the rectangular buoyancy tank 1 is positioned under the water surface by means of the tension provided by the anchor chain 4, so that the draft of the floating breakwater is controlled, the wing plate 3 of the breakwater and the upper end surface of the rectangular buoyancy tank 1 are ensured to be level with the water surface, and therefore, the height of the rectangular buoyancy tank 1 is the draft H designed for the buoyancy tank Draft water The different heights of the rectangular buoyancy tanks 1 will cause the breakwater to have different design draft H Draft water Ultimately affecting the height h of the wing panel 3.
Preferably, the relevant dimensions of the bump 2 are changed according to the different values of the design wave height, as shown in fig. 3 and 4, the invention sets the width b of the bump 2 and the height H1, which is the height from the bottom to the top of the bump 2, and the height h1= (0.6-0.7). H Wave height Wherein H is Wave height Namely, the design wave height;
the whole breakwater adopts a reinforced concrete integral pouring mode, wherein the rectangular buoyancy tank 1 and the convex blocks 2 are subjected to reinforced concrete integral pouring, and the wing plates 3 and the rectangular buoyancy tank 1 are subjected to reinforced concrete integral pouring.
The transmission coefficient is an important index for evaluating the wave eliminating effect of the floating breakwater, and the formula is as follows:
K t =H t /H i wherein H is i For incident wave height in front of dyke, H t Is the wave height behind the dyke. In general, transmissionThe smaller the coefficient, the stronger the wave-absorbing capacity of the floating breakwater, and conversely, the weaker the wave-absorbing capacity.
The breakwater mainly realizes wave elimination by reflecting incident waves, the phase difference between the waves and the motion of the breakwater can also generate certain inhibition and attenuation effects on wave energy transmission in the waves, the deeper the buoyancy tank main body in the breakwater is, the better the wave elimination effect is, and the anchoring force is correspondingly increased.
The rectangular buoyancy tank 1 is fixedly connected with the anchor chains 4, at least 2 pairs of the anchor chains 4 are symmetrically distributed on two sides of the bottom of the rectangular buoyancy tank 1, all the anchor chains 4 are anchored in the anchor weights 5, and the anchor weights 5 are fixed on the sea floor, wherein the rectangular buoyancy tank 1 is anchored by the anchor chains 4 in an splayed anchoring manner, and the anchoring manner can effectively control the motion trend of the rectangular buoyancy tank 1 in the directions of swaying, heaving and the like.
Along with the extension of the breakwater length, anchor chains 4 can be symmetrically arranged on two sides of the bottom of the rectangular buoyancy tank 1 along the extension line direction of the breakwater according to actual needs.
The anchor chain 4 comprises a pair of anchor ropes, the optimal installation angle of the pair of anchor ropes is 22.5 degrees, namely, the plane included angles of the two anchor ropes and the planes in the vertical and horizontal directions are respectively 22.5 degrees, the plane included angle of the planes of the two anchor ropes is 45 degrees, the anchor ropes can effectively decompose the tension on the anchor chain, the tension value of each anchor rope is in a safe range at any time, and the anchor ropes cannot be broken due to the increase of the tension applied to the anchor chain.
The breakwater has a certain draft, so that the wave force born by the breakwater in the wave elimination process is increased, and compared with the traditional floating breakwater, the anchor chain 4 needs to bear larger pulling force, therefore, the anchor rope materials in the anchor chain 4 mainly adopt high-strength stretch-resistant materials.
Example 2

The bottom surface of the anti-collision strip 7 is flush with the bottom surface of the rectangular buoyancy tank 1, the width of the anti-collision strip 7 exceeds the width of the wing plate 3 arranged above, the height of the anti-collision strip 7 is lower than the height of the whole rectangular buoyancy tank 1, as shown in fig. 6, the inner-layer stress steel plate 81 and the outer-layer stress steel plate 82 are sequentially arranged on the anti-collision strip 7 from the side wall surface of the rectangular buoyancy tank 1 outwards, an upper-layer stress steel plate 83 and a lower-layer stress steel plate 84 are fixedly arranged between the inner-layer stress steel plate 81 and the outer-layer stress steel plate 82 respectively, and a metal hollow ball filling resin matrix composite 85 is arranged in a closed space formed by the four stress steel plates.
When the incident waves enter the floating breakwater working water, all the stressed steel plates of the anti-collision strip 7 form a closed whole and deform and bear force together, the filling material between the inner stressed steel plates and the outer stressed steel plates is also a good energy absorbing material, and under the cooperative deformation of the two, the energy absorbing effect is obvious, so that the wave energy contained in the waves can be reduced to a greater extent, and further the damage of the breakwater is reduced.
Example 3
