Description

Technical Field

[0001] The invention relates to the technical field of breakwaters, and in particular to an offshore floating breakwater for generating electricity using wave energy. Background Art

[0002] Floating breakwaters at sea are hydraulic structures used to defend against the invasion of sea waves and form a sheltered water area. Floating breakwaters can not only ensure the safety of the sheltered water area, so that relevant operators or equipment can operate safely and stably in the sheltered water area, but also are more chosen in reality because of their strong adaptability and convenient construction. Wave energy, as a clean, renewable and high-density energy, has great potential for development and utilization. If floating breakwaters can be combined with wave energy power generation technology, not only can the efficient utilization of wave energy be achieved, but also the functionality of floating breakwaters can be further expanded.

[0003] A Chinese patent (Announcement No.: CN108999144B; Announcement Date: 2023.07.25) discloses a comb-type breakwater system integrating an oscillating water column type and a pendulum type power generation device. The comb-type hollow breakwater system includes a riprap base bed, two contraction waterway caissons (chamfered compartments, support plates), a cap plate, an intermediate wing plate, two side wing plates and a breast wall. The contraction waterway caisson is sunk on the riprap base bed, the cap plate, the intermediate wing plate and the caisson support plate are cast as a whole, the two side wing plates and the caisson body are cast as a whole, and a concrete breast wall is cast above the caisson. The comb-type hollow breakwater system uses the caisson compartment on the wave-facing side as an energy-capturing air chamber to complete the power generation of the oscillating water column (OWC) device, and replaces the chamfered caisson compartment with a contraction waterway for wave gathering of the pendulum-type power generation device; the left and right caisson structures are connected as a whole through the middle wing plate, the pedestal plate and the breast wall to improve the overall stability of the structure; the air-permeable structure is maintained at the connection between the two caissons to ensure water exchange. The oscillating water column power generation system uses the caisson compartment on the wave-facing side as an energy-capturing air chamber, and uses double caisson compartments to increase the water inlet volume in the energy-capturing air chamber. At the same time, combined with the vents on the top of the two caisson compartments, the compressed air of the two caisson compartments is concentrated to increase the degree of air compression in the air chamber, thereby improving the conversion efficiency of the oscillating water column power generation system. The pendulum-type power generation system uses the wave-capturing and energy-gathering effects of the contraction waterway. Under the driving action of wave force, the pendulum plate will swing back and forth with the hinge as the axis, driving the hydraulic device to generate electricity, converting the wave energy into hydraulic energy through the pendulum plate, and further converting it into electrical energy through the hydraulic energy power generation component group.

[0004] Although the above patent document can use oscillating water columns to generate wave power on the basis of breakwaters, the above patent document has a complex structure, high cost, and a long gas flow path, resulting in high gas flow losses. The efficiency of using oscillating water columns to generate wave power is too low and the reliability is poor. Summary of the invention

[0020] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0021] Reference below Figure 1-Figure 4 An offshore floating breakwater 100 for generating electricity using wave energy according to an embodiment of the present invention is described.

[0022] Combination Figure 1-Figure 4As shown, the offshore floating breakwater 100 for generating electricity using wave energy according to the present invention may mainly include: a wave-breaking pontoon 10 and a power generation component 20, wherein an oscillating water column chamber 11 is provided inside the wave-breaking pontoon 10, and the oscillating water column chamber 11 is provided with a water inlet and outlet, so that seawater can enter and exit the oscillating water column chamber 11 through the water inlet and outlet under the action of waves, and the oscillating water column chamber 11 is at least partially above the sea surface to selectively inhale or discharge gas, and the power generation component 20 is arranged on the upper side of the wave-breaking pontoon 10 and includes a first air flow conduit 21, a second air flow conduit 22 and a power generation component 23, and the upper and lower ends of the first air flow conduit 21 are respectively provided with a first air inlet 211 and a first air outlet 212, and the upper and lower ends of the second air flow conduit 22 are respectively provided with a first air inlet 211 and a first air outlet 212. A second air outlet 221 and a second air inlet 222 are provided, the first air outlet 212 and the second air inlet 222 are both connected to the oscillating water column chamber 11, the first air inlet 211 and the second air inlet 221 are both connected to the outside atmosphere, the first air inlet 211 and the second air inlet 222 are both provided with an air inlet check valve 24, the first air outlet 212 and the second air outlet 221 are both provided with an air outlet check valve 25, the power generation element 23 is provided between the first air flow duct 21 and the second air flow duct 22, and the two ends of the power generation element 23 are selectively connected to the first air inlet 211 and the second air inlet 222 respectively; or the two ends of the power generation element 23 are selectively connected to the first air outlet 212 and the second air outlet 221 respectively.

[0023] Specifically, by arranging the wave-breaking buoy 10 on the sea surface, the wave-breaking buoy 10 can absorb and dissipate wave energy through its dynamic response characteristics, so that it can provide good protection for the waters that need to be sheltered. At the same time, by arranging an oscillating water column chamber 11 inside the wave-breaking buoy 10, due to the gravity of the wave-breaking buoy 10 itself, a part of the oscillating water column chamber 11 will sink into the sea. When the waves on the sea surface rise and fall, the waves can enter and exit the oscillating water column chamber 11 through the water inlet and outlet of the oscillating water column chamber 11. The oscillating water column chamber 11 is at least partially above the sea surface. When the wave enters the oscillating water column chamber 11, the liquid level in the oscillating water column chamber 11 rises, and the gas in the oscillating water column chamber 11 is lifted up by the sea surface and discharged outwardly. When the wave flows out of the oscillating water column chamber 11, the liquid level in the oscillating water column chamber 11 drops, and the gas is drawn into the oscillating water column chamber 11 from the outside, and this cycle is repeated continuously, so that the gas in the oscillating water column chamber 11 oscillates periodically.

[0024] Furthermore, by arranging the power generation component 20 on the upper side of the wave-breaking buoy 10, and making the upper and lower ends of the first air flow duct 21 respectively provided with the first air inlet 211 and the first air outlet 212, and the upper and lower ends of the second air flow duct 22 respectively provided with the second air outlet 221 and the second air inlet 222, the first air outlet 212 at the lower end of the first air flow duct 21 and the second air inlet 222 at the lower end of the second air flow duct 22 are both connected to the oscillating water column chamber 11, and the first air inlet 211 at the upper end of the first air flow duct 21 and the second air outlet 221 at the upper end of the second air flow duct 22 are both connected to the outside atmosphere.

[0025] When the gas in the oscillating water column chamber 11 is lifted up by the sea surface and discharged outward, the gas in the oscillating water column chamber 11 can flow into the first air flow duct 21 through the first air outlet 212, because the first air inlet 211 and the second air inlet 222 are both provided with an air inlet check valve 24, and the first air outlet 212 and the second air outlet 221 are both provided with an air outlet check valve 25. After the gas flows out from the second air outlet 221, due to the setting of the air inlet check valve 24, the first air inlet 211 and the second air inlet 222 cannot discharge gas, and the gas can only flow from the first air outlet 212 to the outside atmosphere. Therefore, the gas can flow from the first air flow duct 21 to the second air flow duct 22, and the power generation element 23 is set between the first air flow duct 21 and the second air flow duct 22. The airflow flowing from the second air outlet 221 to the first air outlet 212 will pass through the power generation element 23, and the kinetic energy will be converted into electrical energy through the generator.

[0026] Correspondingly, when gas is drawn into the oscillating water column chamber 11 from the outside, due to the setting of the air outlet one-way valve 25, the first air outlet 212 and the second air outlet 221 cannot take in air, and the gas can only enter the first air inlet 211 from the second air inlet 222 through the outside atmosphere, and enter the oscillating water column chamber 11 through the first air inlet 211, that is, the outside atmosphere will enter the first air flow duct 21 from the second air flow duct 22. Since the power generation element 23 is arranged between the first air flow duct 21 and the second air flow duct 22, the air flow will pass through the power generation element 23, and the kinetic energy will be converted into electrical energy through the power generation element 23.

[0027] The present invention is configured in this way, and the structure of the power generation component 20 is simple. It only needs to set two air flow pipes on the upper side of the wave-breaking buoy 10 and set the power generation component 23 between the two air flow pipes to realize the air intake power generation and air outlet power generation of the oscillating water column cavity 11, which can effectively shorten the gas flow path, thereby reducing the gas loss during the flow process, thereby improving the power generation efficiency of the power generation component 23 using wave energy to generate electricity.

[0028] In addition, due to the setting of the air inlet check valve 24 and the air outlet check valve 25, it can be ensured that no matter how the waves on the sea oscillate, for example, even if the waves enter and exit the oscillating water column chamber 11 at an extremely fast frequency, the air flow can pass through the power generation element 23 in one direction, and the gas will not flow back. There is no need to perform special customized modification on the power generation element 23, and the one-way rotation of the air inlet or the one-way rotation of the air outlet can drive the power generation element 23 to generate electricity, which can improve the stability and reliability of the power generation of the power generation element 23.

[0029] In some embodiments of the present invention, the power generating element 23 is a turbine power generating element. The flow of gas can drive the circumferential rotation of the worm gear. The circumferential rotation of the turbine drives the rotor of the power generating element 23 to rotate through a transmission mechanism such as a shaft and a gear box. The rotation of the rotor causes changes in its internal magnetic field. Due to the electromagnetic induction phenomenon, the magnetic flux in the stator coil changes, thereby generating an induced electromotive force in the coil, and then generating current.

[0030] It should be noted that by arranging the power generation component 20 on the upper side of the wave-breaking buoy 10, the power generation component 20 can be prevented from being in continuous contact with the sea surface, thereby preventing the power generation component 20 from being eroded by seawater and damaged by waves, thereby improving the overall stability and reliability of the offshore floating breakwater 100, and increasing the service life of the offshore floating breakwater 100.

[0031] Combination Figure 1 and Figure 2 As shown, there are multiple oscillating water column cavities 11, which are separated from each other inside the wave-breaking buoy 10, and there are multiple power generation components 20, which are connected to the multiple oscillating water column cavities 11 in a one-to-one correspondence.

[0032] Specifically, by providing a plurality of oscillating water column cavities 11, and making a plurality of power generation components 20 connected to the plurality of oscillating water column cavities 11 in a one-to-one correspondence, each power generation component 20 can independently perform power generation work. On the one hand, the power generation efficiency of the plurality of power generation components 20 can be improved. On the other hand, when some of the plurality of power generation components 20 are damaged and cannot generate electricity normally, maintenance personnel only need to repair the power generation components 20 that cannot generate electricity normally, and there is no need to repair all the power generation components 20. In addition, other undamaged power generation components 20 can still generate electricity normally during this period, thereby improving the power generation stability of the offshore floating breakwater 100.

[0033] In some embodiments of the present invention, the electricity generated by multiple power generation components 20 can be concentrated in the power storage device through the cable lines arranged on the offshore floating breakwater 100. Due to the intermittent nature of wave energy, supercapacitors can be used for short-term high-power electrical energy storage, and lithium batteries can be used for long-term storage to achieve stable output.

[0034] Combination Figure 2 As shown, a water regulating chamber 12 is also provided in the wave-breaking buoy 10, and a water pump is provided in the water regulating chamber 12. The water regulating chamber 12 is provided with a water inlet 121 and a water outlet 122. The water pump selectively controls the water inlet 121 and the water outlet 122 to adjust the draft of the wave-breaking buoy 10 by adjusting the water volume inside the water regulating chamber 12.

[0035] Specifically, by providing a water-carrying regulating chamber 12 in the wave-breaking buoy 10, and adjusting the water inlet 121 and the water outlet 122 through the water pump member in the water-carrying regulating chamber 12, the water carrying amount inside the water-carrying regulating chamber 12 can be adjusted, thereby adjusting the overall weight of the wave-breaking buoy 10, thereby adjusting the draft of the wave-breaking buoy 10, so that the wave-breaking buoy 10 can play a good protective role against waves under different sea conditions, and the power generation component 20 can generate electricity stably under different sea conditions.

[0036] It should be noted that when the draft of the wave-breaking buoy 10 needs to be reduced, the water pump can pump the water in the water-carrying regulating chamber 12 out of the water outlet 122 , and when the draft of the wave-breaking buoy 10 needs to be increased, the water pump can pump water from the sea into the water-carrying regulating chamber 12 from the water inlet 121 .

[0037] Combination Figure 2 As shown, the wave-breaking buoy 10 is rectangular, and there are multiple water-carrying regulating chambers 12, and the multiple water-carrying regulating chambers 12 are arranged at each end corner of the wave-breaking buoy 10. Specifically, by setting the wave-breaking buoy 10 in a rectangular shape, the wave-breaking buoy 10 has four end corners, and multiple water-carrying regulating chambers 12 are arranged at the four end corners of the wave-breaking buoy 10, the water-carrying regulating chambers 12 can not only adjust the draft of the wave-breaking buoy 10, but also adjust the tilt angle of the wave-breaking buoy 10 by setting the weights of the water-carrying regulating chambers 12 at the four end corners of the wave-breaking buoy 10 to be different, so that the wave-breaking buoy 10 can be more adapted to different sea conditions.

[0038] Combination Figure 1-Figure 3 As shown, a wave-breaking bamboo net 30 is provided at the lower side of the wave-breaking buoy 10, and the width of the wave-breaking bamboo net 30 is extended in the first direction. Specifically, by providing the wave-breaking bamboo net 30 at the lower side of the wave-breaking buoy 10, when the wave passes through the wave-breaking bamboo net 30, the wave-breaking bamboo net 30 can buffer and absorb the wave, thereby reducing the energy of the wave and improving the wave-breaking effect of the entire offshore floating breakwater 100.

[0039] Furthermore, due to the water permeability of the grids on the wave-breaking bamboo net 30, the wave-breaking bamboo net 30 will not be subjected to too much wave force, which can increase the overall service life of the offshore floating breakwater 100.

[0040] In addition, since the wave-breaking bamboo net 30 is made of bamboo, the wave-breaking bamboo net 30 can be made stronger and cheaper, and the low density can also provide buoyancy for the whole net.

[0041] It should be noted that the first direction is the up-down direction perpendicular to the sea surface, which can increase the contact area between the wave-breaking bamboo net 30 and the waves, thereby further improving the wave-breaking effect of the wave-breaking bamboo net 30.

[0042] Combination Figure 1-Figure 3 As shown, the length of the wave-breaking bamboo net 30 is extended in the second direction, and there are multiple wave-breaking bamboo nets 30, and the multiple wave-breaking bamboo nets 30 are arranged at intervals in the third direction, wherein the first direction, the second direction and the third direction are perpendicular to each other. Specifically, by extending the length of the wave-breaking bamboo net 30 in the second direction, the length of the wave-breaking buoy 10 is also extended in the second direction, so that all waves passing through the wave-breaking buoy 10 can be buffered and absorbed by the wave-breaking bamboo net 30, which can further improve the reliability and wave-breaking effect of the wave-breaking bamboo net 30.

[0043] Furthermore, the wave-breaking bamboo nets 30 are arranged in plurality, and the plurality of wave-breaking bamboo nets 30 are arranged at intervals in the third direction, so that the plurality of wave-breaking bamboo nets 30 can play multiple wave-breaking roles on waves, thereby improving the overall wave-breaking effect of the offshore floating breakwater 100. It should be noted that one of the second direction and the third direction is the left-right direction, and the other is the front-back direction.

[0044] In some embodiments of the present invention, the upper end of the wave-breaking bamboo net 30 is connected to the wave-breaking buoy 10, and an inclined support member 31 is provided between the lower end of the wave-breaking bamboo net 30 and the wave-breaking buoy 10. The support member 31 is located on the side of the wave-breaking bamboo net 30 away from the waves, and can support the wave-breaking bamboo net 30 when the waves hit the wave-breaking bamboo net 30, thereby improving the wave-breaking stability of the wave-breaking bamboo net 30. In addition. Each wave-breaking bamboo net 30 is provided with a plurality of support members 31, and the plurality of support members 31 are arranged at intervals in the second direction.

[0045] Combination Figure 3 and Figure 4 As shown, there are multiple wave-breaking buoys 10, and a damping connector 40 is connected between two adjacent wave-breaking buoys 10. Specifically, by setting the wave-breaking buoys 10 as multiple wave-breaking buoys, the wave-breaking effect of the floating breakwater 100 at sea can be improved. Further, by connecting the damping connector 40 between two adjacent wave-breaking buoys 10, when the wave oscillation causes the two adjacent wave-breaking buoys 10 to move relative to each other, the damping member 44 can damp the relative shaking of the two wave-breaking buoys 10, so that the amplitude of the mutual movement between the two wave-breaking buoys 10 can be reduced, thereby improving the overall stability of the floating breakwater 100 at sea.

[0046] In some embodiments of the present invention, a plurality of wave-breaking buoys 10 can be combined and adjusted according to different sea conditions, which is convenient for installation, disassembly and maintenance, thereby improving the adaptability and economy of the project.

[0047] In some embodiments of the present invention, multiple wave-breaking buoys 10 can be connected in pairs to form a row or enclose a closed area to protect internal marine facilities such as offshore photovoltaic platforms, floating wind turbines or other facilities, prevent them from being damaged by waves, and reduce the impact of waves on their stability. At the same time, they can also generate electricity to provide a certain amount of energy supply for marine equipment or provide supplementary power generation for offshore power plants to increase benefits.

[0048] Combination Figure 4 As shown, the damping connecting member 40 includes a fixed rod 41, a rotating connecting member 42, a rotating rod 43 and a damping member 44. There are two fixed rods 41 and they are respectively arranged on two adjacent wave-breaking buoys 10. The rotating connecting member 42 is arranged on the fixed rod 41. The damping member 44 is arranged between the two fixed rods 41. One end of the rotating rod 43 is rotatably connected to the rotating connecting member, and the other end is connected to the damping member 44. Specifically, by respectively arranging two fixed rods 41 on two adjacent wave-breaking buoys 10, and making sure that the two fixed rods 41 are each provided with a rotating connecting piece 42, and making sure that the damping piece 44 is arranged between the two fixed rods 41, one end of the rotating rod 43 is rotatably connected to the rotating connecting piece 42, and the other end of the rotating rod 43 is connected to the damping piece 44, the force generated by the relative movement between the two adjacent wave-breaking buoys 10 will act on the damping piece 44 through the rotating rod 43, and the damping force generated inside the damping piece 44 will buffer, reduce or even eliminate the force generated by the relative movement between the two adjacent wave-breaking buoys 10, which can not only make the two adjacent wave-breaking buoys 10 more stable, but also improve the service life of the rotating rod 43.

[0049] Furthermore, by rotatably connecting the rotating rod 43 to the rotating connecting member 42 , compared with a hard connection, this can prevent damage to the connection between the rotating rod 43 and the rotating connecting member 42 , and can further improve the service life of the damping connecting member 40 .

[0050] Combination Figure 1 and Figure 3As shown, the side of the wave-facing buoy 10 facing the waves is set as a wave-facing curved surface 13. Specifically, by setting the side of the wave-facing buoy 10 facing the waves as the wave-facing curved surface 13, the wave-facing curved surface 13 can improve the wave reflection ability of the wave-breaking buoy 10. When the waves pass through the wave-breaking buoy 10, the wave-facing curved surface 13 can better reflect the sea surface waves and disperse the impact of the waves on the wave-breaking buoy 10, which can further improve the wave dissipation effect of the offshore floating breakwater 100, thereby improving the stability and reliability of the offshore floating breakwater 100.

[0051] Combination Figure 1 and Figure 3 As shown, the offshore floating breakwater 100 may also mainly include a mooring rope 50, one end of which is connected to the breakwater pontoon 10, and the other end of the mooring rope 50 is provided with an anchor block 51. Specifically, two hanging ears 15 are provided on each side of each breakwater pontoon 10, and one end of the mooring rope 50 is connected to the hanging ear 15 of the breakwater pontoon 10, and the other end of the mooring rope 50 is provided with an anchor block 51, and the anchor block 51 can be connected and fixed to the seabed, which can not only prevent the breakwater pontoon 10 from moving too much under the action of waves, but also prevent the relative displacement between two adjacent breakwater pontoons 10 from being too large, resulting in dislocation or collision of the two adjacent breakwater pontoons 10, so as to improve the overall stability of the offshore floating breakwater 100.

[0052] In some embodiments of the present invention, the anchor block 51 can also selectively adjust the tension state of the mooring rope 50 according to different sea conditions and the use environment of the offshore floating breakwater 100, thereby further improving the fixing effect of the mooring rope 50 on the offshore floating breakwater 100.

[0053] In some embodiments of the present invention, rubber fenders 14 can be set on the circumferential edge of the wave-breaking buoy 10, and a plurality of rubber fenders 14 are arranged at intervals on the circumferential edge of each wave-breaking buoy 10. The rubber fenders 14 can not only buffer the collision between the wave-breaking buoy 10 and external equipment, but also buffer the collision between two adjacent wave-breaking buoys 10.
