In order to fully realize the wave-breaking function of the buoyancy tank of the embodiment, the openings 102 of the upper floating body 100 and the wave-breaking cavities 702 of the lower floating body 700 of the buoyancy tank at the transverse part and the longitudinal part are arranged right opposite to the wave-facing side, so that the design not only enables the invasion of underwater waves to drive the rotating blades 207 of the rotating assembly to rotate through the openings 102 or push the swinging plates 706 to move towards the inner sides of the wave-breaking cavities 702 through the wave-breaking cavities 702, but also plays a wave-breaking role through the rotation of the rotating blades 207 and the movement of the swinging plates 706.
Example 2:
referring to fig. 6, on the basis of the floating breakwater with intelligent power generation of embodiment 1, the side openings 103 suitable for water flow to pass through are also formed on the left and right side walls of the upper floating body of the floating breakwater with intelligent power generation of this embodiment, so that the advantage of the design is that when waves in different directions invade the buoyancy tank, the rotating blades 207 on the rotating shaft 204 can induce the waves in different directions to rotate through the openings 102 or 103 on the buoyancy tank.
Example 3:
referring to fig. 4, on the basis of the intelligent power generation floating breakwater of embodiment 1 or embodiment 2, a plurality of rows of netting 500 are rigidly connected to the bottom of the lower floating body of the intelligent power generation floating breakwater of this embodiment; the netting 500 is vertically arranged relative to the buoyancy tank; a plurality of meshes 504 are uniformly distributed on the netting 500; the bottom of the netting 500 is provided with a sinker 600. The plurality of rows of netting 500 may be alternatively arranged as three rows of netting 500. Because the flotation tank of intelligence power generation's floating breakwater is more shallow of draft under the effect of buoyancy, it can drive rotating assembly's rotatory leaf 207 rotation to be difficult to guarantee that the invasion and attack of wave under water certainly, consequently through netting 500 and the sinker 600 that sets up, apply the power of pulling to the bottom of flotation tank, thereby increase the vertical depth of flotation tank, make the flotation tank can reflect the longer wave of wavelength, the invasion and attack of wave under water can drive rotating assembly's rotatory leaf 207 rotatory, and mesh 504 on the netting 500 can also increase the unrestrained effect of disappearing of flotation tank.
The netting 500 is formed of a rigid structure, such as, but not limited to, an aluminum alloy or a steel material, to increase the rigidity of the netting 500.
Preferably, as shown in fig. 7, in order to further improve the wave dissipation effect of the floating breakwater with intelligent power generation of this embodiment, a rotating pipe 501 is rotatably disposed at the edge of each mesh 504 of the netting 500, a rubber layer 503 is wrapped on the outer side of the rotating pipe 501, a rubber blade 502 is further disposed on the rotating pipe 501, the rubber layer 503 plays a role in buffering and energy absorption, and the wave can drive the rotating pipe 501 to rotate through the rubber blade 502, so that the kinetic energy of the wave is converted into the kinetic energy of the rotation of the rotating pipe 501, thereby consuming the kinetic energy of the wave and achieving the wave dissipation effect.
Alternatively, in order to improve the stability of the rotating tube 501 during the rotation process, the same rotating tube 501 may be simultaneously passed through the corresponding meshes 504 of at least two adjacent rows of netting 500.
