Description

Technical Field

[0001] The invention relates to the technical field of wind and wave power generation and breakwater engineering, and in particular to a wind and wave power generation buoyancy box breakwater and a working method thereof. Background Art

[0002] Breakwaters are usually located in areas where ocean wave energy is relatively concentrated. If the wave energy originally consumed and blocked by the breakwater is converted into electrical energy to form a power-generating breakwater, while achieving the effect of wave dissipation, it can also improve the utilization of clean and renewable energy in the ocean, which will be a good development direction. Wind energy and wave energy are both abundant renewable energy sources in the ocean, and they are complementary to each other in time and space. Compared with single wind or wave power generation, complementary power generation can make up for the intermittent and instability of their respective energy supplies to a certain extent, making the power generation output more stable and reliable. If these two energy sources are integrated and reasonably used in a power-generating breakwater, electricity can be obtained more stably and efficiently.

[0003] Among the existing breakwater structures, the floating box breakwater technology is relatively mature and can be flexibly designed and adjusted. It is especially suitable for sea areas with large water depths and complex seabed topography. However, its structural motion response is large and the wave-breaking effect needs to be improved. There are relatively few types of floating box breakwaters with power generation functions. Most of them are single-use energy such as wind and waves. There are also common problems such as low energy utilization, inability to effectively combine wave-breaking and power generation functions, general wave-breaking effect or unstable power generation.

[0004] Chinese invention patent: Announcement number is "CN110952498B", and the name is "A floating breakwater with both wave-breaking and power generation functions", which discloses a floating breakwater with both wave-breaking and power generation functions, including a floating breakwater unit, which includes an upper floating body and a wave-breaking structure, and the wave-breaking structure includes a shaking power generation unit and a water turbine power generation unit. The shaking power generation unit uses wave energy to shake and generate electricity, and the water turbine power generation unit uses water flow energy to rotate and generate electricity, so that the coil cuts the magnetic flux lines to generate electricity, and generates electricity by magnetoelectricity. This technical solution gathers energy through the shaking power generation unit and the water turbine power generation unit, and the miniaturized energy collection unit overcomes the unstable characteristics of wave energy, realizes the simultaneous use of water flow energy and wave energy, and at the same time, the damping structure composed of the power generation unit is used to break the wave, thereby realizing the integration of wave-breaking and power generation. However, in the upper floating body of the technical solution, the shaking power generation units are arranged between adjacent hollow cylindrical tubes and staggered with the hollow cylindrical tubes. This means that when waves come, the shaking force of the power generation units will be significantly slowed down due to the obstruction of the hollow cylindrical tubes, thereby affecting the shaking power generation. In addition, in the wave-breaking structure, each layer is provided with three shaking power generation units or three hydro-turbine power generation units, which may result in the back-wave side unit components being subjected to small forces, the shaking power generation units not shaking sufficiently, or the hydro-turbine power generation units not starting, thereby also affecting the power generation performance. The wave-breaking structure of the technical solution utilizes the cylindrical structure of the power generation unit to reflect the wave energy and the collision and friction between the cylinder and the waves to break the waves, but the wave-breaking structure only includes six shaking power generation units and six hydro-turbine power generation units. If a better wave-breaking effect is to be achieved, the unit components need to be large and dense, and this situation is not conducive to the shaking of the shaking power generation unit and the rotation of the hydro-turbine power generation unit, thereby affecting the power generation effect, that is, the wave-breaking and power generation functions will affect each other and cannot meet the needs at the same time. However, the wave-breaking effect of the technical solution is not good. Summary of the invention

It converts the horizontal thrust of wave energy into mechanical energy for the rotation of the floating ball and converts the vertical lifting force of wave energy into mechanical energy for the up and down movement of the oscillating structure.

Multiple power generation methods complement each other, and power generation is continuous and stable.

[0025] 3. The buoy-type breakwater unit has a small motion response and restoring force, and is highly practical. Under the action of waves, the breakwater unit is subjected to the horizontal and vertical forces of the waves, which in turn causes the buoy to rotate and the oscillating structure to slide up and down, which consumes the force on the structure due to work, which is beneficial to both wave dissipation and reducing the vibration and restoring force of the breakwater unit.

The first rotating rod 26 and the center of the floating ball 25 are in the same horizontal plane. The first rotating rod 26 is preferably arranged at the top center of the second cavity 16, that is, the centerline diameter of the first rotating rod 26 = the outer diameter of the inner layer 13 - the top width D of the inner layer 13. Similarly, the second rotating rod 27 is also preferably arranged at the center of the third cavity 18. A plurality of second connecting rods 29 are vertically fixedly connected below the first rotating rod 26, and each second connecting rod 29 is provided with a second permanent magnet 32. A plurality of fourth connecting rods 31 are vertically fixedly connected below the second rotating rod 27, and each fourth connecting rod 31 is provided with a third permanent magnet 33.

The inner layer 13 is provided with a through groove along the circumferential direction at the corresponding position of the first connecting rod 28, so that the first connecting rod 28 can rotate around the middle column 7 driven by the floating ball 25. An annular through groove is provided on the top surface 34 of the outer layer 14 at a position corresponding to the third connecting rod 30 , so as to facilitate the third connecting rod 30 to rotate around the central column 7 driven by the floating ball 25 .The sliding seam between the first connecting rod 28 and the inner layer 13, the sliding seam between the third connecting rod 30 and the top surface 34, and the sliding seam of the rod 11 along the slide plate 8 are all sealed, which is a prior art and will not be described in detail here. The sliding seam is the through groove.

[0037] In some embodiments, a limit card 35 is provided between the first connecting rod 28 and the inner layer 13 and between the third connecting rod 30 and the top surface 34 to limit the floating ball 25 to rotate only around the central structure 1 and not to move vertically or horizontally. In order to prevent the limit card 35 from being corroded by seawater, the limit card 35 is preferably provided on the inner side of the inner layer 13 and the outer layer 14.

[0038] In some embodiments, the wind power generation system 3 is composed of a support rod 36, an upper plate 37, a lower plate 38, a wind plate structure 39, a speed increasing gear 40 and a first generator 41. The support rod 36 is fixed on the top plate 5, preferably fixed in the middle of the top plate 5. The upper plate 37 is fixed to the top of the support rod 36, and the lower plate 38 is fixed to the middle of the support rod 36. The wind plate structure 39 is composed of a wind plate 42 and a sleeve rod 43. The sleeve rod 43 is sleeved on the support rod 36 and is rotatably connected to the support rod 36. The wind plate 42 is fixed on the sleeve rod 43, the number of the wind plates 42 is greater than two, and they are one-way plates, and the wind plates 42 can be semi-cylindrical or spiral. The sleeve rod 43 can rotate around the support rod 36 within a fixed range. The top of the sleeve rod 43 is equipped with a speed increasing gear 40 that rotates with the sleeve rod 43, and the upper plate 37 is equipped with the first generator 41 that is transmission-connected to the speed increasing gear 40.

[0039] In some embodiments, a ballast 44 may be provided at the bottom of the bottom plate 6. The mooring system 4 is connected to the middle of the bottom plate 6 or the ballast 44, or to connection points evenly distributed on the circumference of the bottom plate 6 or the ballast 44.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments, the horizontal cross section of the outer layer 14 is symmetrical along the wave direction and the direction perpendicular to the wave. The outer surface of the outer layer 14 includes a wave-facing surface 20, a wave-receiving surface 21, two side surfaces 22 and a transition surface 23. The wave-facing surface 20 and the wave-receiving surface 21 are two arc surfaces of the same first cylinder 24 and are symmetrical along the direction perpendicular to the wave. The two side surfaces 22 are both planes, symmetrical along the wave direction and parallel to the wave direction. The two side surfaces 22 are both circumscribed to the first cylinder 24, and the width B of the side surface 22 is smaller than the diameter of the first cylinder 24. The wave-facing surface 20 and the wave-receiving surface 21 are connected by a transition surface 23. The transition surface 23 is an arc surface.

[0041] The horizontal plane where the center of the buoy 25 is located is a still water surface, the top plate 5 is flush with the still water surface, and the central structure 1 is flush with the bottom of the oscillating structure 2. The height H of the central structure 1 is 1 to 3 meters higher than the wave height, the ratio of the length L of the pontoon-type breakwater unit to the incident wavelength is greater than 0.25, the diameter of the top plate 5 is ≥ L / 3, the width C of the top surface 34 is ≥ the top width D of the inner layer 13. The height of the inner layer 13 is greater than H. The third connecting rod 30 is shorter to increase the length of the fourth connecting rod 31, which is conducive to full power generation. The upper plate 37 and the lower plate 38 are the same circular thin plates with a diameter smaller than the diameter of the top plate 5. The size of the wind plate 42 does not exceed the upper plate 37 and the lower plate 38. The distance from the lower plate 38 to the top plate 5 is greater than the wave height / 2 to prevent waves from affecting the operation of the wind plate. The upper and lower ends of the first stator 10 are provided with gaskets 45 to reduce the impact force and prevent damage. The height of the first stator 10 is less than the height H of the central structure 1-wave height.

[0042] The present invention also provides a working method applicable to the wind wave power generation pontoon breakwater of the present invention, comprising the following steps:

[0043] Step 1: Arrange a number of pontoon breakwater units in sequence along the vertical direction of the waves, and moor each pontoon breakwater unit separately to form a whole breakwater.

[0044] Step 2: Place the pontoon breakwater unit in the water and adjust the height so that the center of the top plate 5 and the floating ball 25 are flush with the still water surface.

[0045] Step 3: When waves act on the breakwater, part of the waves are reflected by the outer layer 14 and the inner layer 13, part of the waves hit the buoy 25, causing the buoy 25 to rotate around the central structure 1, and part of the waves cause the inner layer 13 and the central structure 1 to slide up and down.

[0046] Step 4: The float 25 rotates to drive the first connecting rod 28 and the third connecting rod 30 to rotate. The first connecting rod 28 in turn drives the first rotating rod 26 and the second connecting rod 29 to rotate, thereby driving the second permanent magnet 32 ​​to rotate and cut the magnetic flux lines to generate electricity; the third connecting rod 30 drives the second rotating rod 27 and the fourth connecting rod 31 to rotate in turn, thereby driving the third permanent magnet 33 to rotate and cut the magnetic flux lines to generate electricity.

[0047] Step 5: The inner layer 13 slides up and down, driving the first stator 10 to slide up and down, thereby cutting the magnetic flux lines to generate electricity.

[0048] Step 6: Under the action of wind, the wind plate 42 rotates, which in turn drives the sleeve rod 43, the speed increasing gear 40 and the rotor of the first generator 41 to rotate, thereby generating electricity.

[0049] From the perspective of wave-breaking function, when waves act on the breakwater, part of them will be reflected back by the outer layer 14 and the upper part of the inner layer 13. Because the radii of the outer layer 14 and the inner layer 13 are different, there is a phase difference between the two reflections. Because the wave-facing side of the outer layer 14 is a concave-convex surface composed of a wave-facing surface 20 and two transition surfaces 23, the reflections between different surfaces on the wave-facing side of the outer layer 14 also have a phase difference, which improves the wave-breaking effect; part of the waves will produce a shallow water effect on the top surface 34 of the outer layer 14, thereby reducing the wave energy; part of the wave energy will be converted into mechanical energy for the rotation of the buoy 25 and the heaving and sinking movement of the oscillating structure 2. From the perspective of power generation function, under the action of waves, the buoy 25 will drive the oscillating structure 2 to slide back and forth along the central structure 1. At the same time, under the combined action of waves and water flow between the breakwater units, the buoy 25 will reciprocate around the central structure 1, thereby driving the second connecting rod 29 and the fourth connecting rod 31 to reciprocate around the central structure 1. In addition, the rotation of the wind plate 42 under the action of wind will drive the first generator 41 to generate electricity. The buoy-type breakwater unit has four power generation modes, including generating electricity by cutting the magnetic flux lines through the reciprocating sliding of the oscillating structure 2 in the first cavity 9, generating electricity by cutting the magnetic flux lines through the reciprocating rotation of the second connecting rod 29 in the second cavity 16, generating electricity by cutting the magnetic flux lines through the reciprocating rotation of the fourth connecting rod 31 in the third cavity 18, and generating electricity by wind power through the rotation of the wind plate 42.

[0050] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
