[0002] A breakwater is a hydraulic structure that forms a sheltered area to protect against wave intrusion. Located on the outer perimeter of a port, it also protects against drifting sand and ice floes, ensuring sufficient water depth and a stable surface within the port to meet the requirements for ships to berth, load and unload, and navigate.
[0003] The existing breakwater encloses the port, allowing only entrances and exits, which obstructs the flow of water inside and outside the port, affecting water quality and fish farming. Utility Model Content

[0009] Furthermore, an extension plate is provided on the rear side of the inlet grille, and a plurality of wave-damping ridges are provided on the upper part of the extension plate, the height of the wave-damping ridges being the same as the height of the holes in the inlet grille.
[0010] Furthermore, the return plate is disposed above the wave-damping ridge, and the end of the return plate is a U-shaped groove, which is located behind the wave-damping ridge.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1 As shown, a breakwater for port and waterway engineering includes: a riprap foundation 1 on the seabed; multiple stacked blocks 2 on top of the riprap foundation 1; a wave-damping box 3 above the topmost stacked block 2, with an inlet grille 31 at the front end of the wave-damping box 3; a wave-damping assembly 4 inside the wave-damping box 3, the wave-damping assembly 4 including a wave-damping ridge 41 and a return flow plate 42; a flow guide assembly 5 behind the wave-damping assembly 4; a buffer slope 6 in front of the wave-damping box 3; and a flow divider 7 above the buffer slope 6, the flow divider 7 being connected to the buffer slope 6 by ropes.
[0025] The construction of the riprap foundation 1 involves transporting stones to the breakwater construction site by transport ships, dumping them into the water, and then using a heavy hammer to compact them to increase their density. The specific method can be found in existing technologies.
[0026] The composite block 2 is made of concrete, prefabricated on the shore, and then installed on the riprap foundation 1. Figure 2 As shown, the bottom of the composite block 2 has a groove 21, and the top of the composite block 2 has a protrusion 22. The protrusion 22 of the lower composite block 2 can be inserted into the groove 21 of the upper composite block 2. The cooperation between the groove 21 and the protrusion 22 allows the composite blocks 2 to be accurately positioned when stacked. The composite block 2 in contact with the rubble bed 1 does not have a groove 21 and is directly installed above the rubble bed 1. The concrete has a large self-weight and can withstand the impact of sea waves.
[0027] like Figure 3As shown, the rear end of the wave-damping box 3 is an outflow grille 32. Both the inflow grille 31 and the outflow grille 32 are made of concrete. Both the inflow grille 31 and the outflow grille 32 are located on a base, which is installed above the uppermost stacked block 2. The holes of the inflow grille 31 face the gaps between the holes of the outflow grille 32. Water waves entering through the holes of the inflow grille 31 are blocked by the gaps between the holes of the outflow grille 32 when flowing out, thereby reducing water waves. The tops of the inflow grille 31 and the outflow grille 32 are on the same plane.
[0028] The top of the breakwater 3 is detachably connected to a top cover 33, which is made of steel plate and is galvanized to prevent it from rusting quickly. The top of the inlet grille 31 and the outlet grille 32 are both provided with connecting grooves 34, which are recessed downwards. The bottom of the top cover 33 is provided with a plug 331, which is the same size as the connecting groove 34. The plug 331 can be inserted into the connecting groove 34. When the top cover 33 shows signs of rust or the components inside the breakwater 3 need to be repaired, the top cover 33 can be lifted upwards. Under normal circumstances, the weight of the top cover 33 can withstand the impact of waves.
[0029] An extension plate 311 is provided on the rear side of the inlet grille 31. The extension plate 311 is located at the gap between the holes of the inlet grille 31. Multiple wave-dissipating ridges 41 are provided on the upper part of the extension plate 311. The height of the wave-dissipating ridges 41 is the same as the height of the holes of the inlet grille 31. Both the front and rear sides of the wave-dissipating ridges 41 are inclined surfaces. The kinetic energy of the water wave impacting the wave-dissipating ridges 41 is reduced. Multiple wave-dissipating ridges 41 perform multiple energy dissipation operations, thereby reducing or even dissipating the impact of the water wave.
[0030] A return plate 42 is positioned above the wave-dissipating ridge 41, with a U-shaped channel 421 at its end. The U-shaped channel 421 is located behind the wave-dissipating ridge 41. The U-shaped channel 421 is also located at the gap between the holes in the inlet grid 31. The bottom of the U-shaped channel 421 is lower than the top surface of the wave-dissipating ridge 41. If the water waves passing through the wave-dissipating ridge 41 still have kinetic energy, they will impact the U-shaped channel 421 to return, thereby canceling out subsequent water waves, or impacting the wave-dissipating ridge 41 again to further reduce the energy of the water waves.
[0031] The flow guiding component 5 includes a support rod 51 and a flow guiding wheel 52. The flow guiding wheel 52 is located behind the U-shaped groove 421. The support rod 51 has an annular groove 511 recessed inside, and the flow guiding wheel 52 is rotatably connected to the annular groove 511. The side wall of the flow guiding wheel 52 has three Y-shaped plates 521 arranged in annular array. If a small amount of water wave remains after the energy is dissipated by the U-shaped groove, the water wave will impact the Y-shaped plates 521, thereby causing the flow guiding wheel 52 to rotate and convert energy, further reducing the water wave flow.
[0032] This device uses the energy dissipation of the wave-dissipating ridge 41, the energy dissipation of the U-shaped trough 421, and the energy conversion of the guide wheel 52 to achieve multiple energy dissipation and wave reduction of the water waves entering the wave-dissipating box 3, thereby keeping the water flow behind the outflow grid 32 calm.
[0033] The buffer slope 6 is located above the support pile 61, and the bottom of the support pile 61 is anchored to the seabed. The installation method of the support pile 61 adopts the existing technology. The buffer slope 6 is above the support pile 61, and the highest point of the buffer slope 6 contacts the bottom of the inlet grid 31. The buffer slope 6 is a component in front of the wave-damping box 3. The water flow first impacts the buffer slope 6 for preliminary energy dissipation.
[0034] Several floating barrels 71 are rotatably connected to the diverter plate 7. Under the buoyancy of the floating barrels 71, the diverter plate 7 floats on the water surface. The rope restricts the diverter plate 7 to float only above the buffer slope 6. There are gaps between adjacent floating barrels 71. When surface water waves pass through the floating barrels 71, they are dispersed by the gaps between the floating barrels 71, reducing some of the impact force, and then enter the wave-dissipating box 3 for further energy dissipation.
[0035] The buffer slope 6 and the diversion plate 7 initially weaken the water waves, reducing the probability of damage to the internal components of the wave-damping box 3 and improving the service life of the device.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
