Description

Technical Field

[0001] The present invention relates to the technical field of wave power generation and breakwater engineering, and in particular to an assembled thin film floating power generation breakwater and a method of using the same. Background Art

[0002] Offshore breakwaters are generally long, stretching for kilometers. They are mainly used to reduce wave energy and provide relatively stable waters for ports. Breakwaters are often areas rich in wave energy. If wave energy can be utilized to provide both wave protection and power generation functions, it will be a very beneficial development direction for breakwaters.

[0003] Floating breakwaters are economical, easy to install and maintain, and have significant advantages in deep water areas. Among them, pontoon breakwaters are relatively mature and widely used. In recent years, to overcome their problems such as small inherent period and high restoring force, the structural form of this type of breakwater has been continuously improved and upgraded. Among them, composite floating breakwaters composed of rigid pontoons combined with flexible membranes have attracted widespread attention due to their advantages. This composite floating breakwater combines the characteristics of rigid pontoons and flexible materials, and is effective in wave absorption and structural motion response. However, it generally lacks power generation capabilities. Composite floating breakwaters that can generate power also suffer from insufficient energy utilization, poor integration of wave absorption and power generation functions, loss of balance, complex structure, and inconvenient construction.

[0004] A Chinese invention patent, published with publication number CN115852894A and titled "A Floating Breakwater Duplicating a Flexible Airbag Wave Energy Power Generation Device," discloses a floating breakwater that can also serve as a flexible airbag wave energy power generation device. The breakwater comprises a breakwater body, an airbag system, an air guide system, a power generation system, a ballast tank system, and an anchoring system. The airbag system is connected to the bottom of the breakwater body, while the air guide system is located within the body. The airbag system and the air guide system are interconnected, with the air inlet of the airbag system connected to the air outlet of the air guide system, and the air outlet of the airbag system connected to the air inlet of the air guide system. The power generation system is installed within the air guide system. Ballast tank systems are symmetrically located on both sides of the breakwater body, and an anchoring system is also connected to the breakwater body. This technical solution combines the functions of a flexible airbag wave energy power generation device with a floating breakwater. The flexible airbag wave energy power generation device provides a certain degree of wave damping when generating electricity using wave energy, which can improve the wave-breaking performance of the floating breakwater to a certain extent. However, the flexible airbag wave energy generator in this technical solution uses the deformation of the flexible airbag to propel gas through the ventilation duct, generating electricity using the power generation system in the duct, converting the mechanical energy of the gas flow into electrical energy. However, the flexible airbag is located at the bottom of the box-shaped breakwater body, which is relatively low. Generally, the bottom of the pontoon is subject to less wave impact load, which results in less deformation of the flexible airbag and less ability to generate gas flow, resulting in insufficient power generation and low efficiency.

[0011] Furthermore, the support rod is arranged at the middle position of the pontoon and close to the side plate.

[0012] Furthermore, the speed increasing gear is arranged on the side of the gear c away from the side plate.

[0013] Furthermore, the length of the side plate is the length L of the breakwater unit, the length of the front plate is the width B of the breakwater unit, and the total height of the pontoon and the frame is the height H of the breakwater unit; the ratio of the length L of the breakwater unit to the incident wavelength is greater than 0.25, the height H is 2m higher than the wave height, and the width B is 1 / 2 of the incident wavelength.

[0015] The present invention also provides a method for using the assembled thin-film floating power generation breakwater provided by the present invention, and the specific steps are as follows:

[0016] Step 1: Arrange and combine multiple breakwater units according to actual wave protection requirements, with the front plate on the wave-facing side, and connect them through chain links to form a breakwater as a whole;

[0021] 1. Excellent wave dissipation effect and diverse methods. When waves hit the breakwater, the membrane and the buoys will rise and fall under the action of the waves, thereby converting the wave energy into kinetic energy to dissipate the waves. Wave dissipation is achieved through reflection and friction between the buoyancy boxes, the buoys and the water. The central holes in the middle layers of the membrane also help to form wave trains, further disrupting the water flow and thus dissipating the waves.

[0022] 2. High wave energy utilization and continuous power generation. First, the floating plate generates electricity in both directions, generating electricity both when raised and lowered. Second, the gear rotation and magnetic field line cutting generate electricity simultaneously. As the floating plate moves, it continuously cuts magnetic field lines to generate electricity, while the speed-increasing gear also continuously rotates to drive the generator, thus fully utilizing wave energy. Third, the speed-increasing gear is designed to rotate counterclockwise to generate electricity, eliminating the need for direction change. This reduces energy loss, simplifies components, and effectively connects the movements of components.

[0023] 3. Convenient and efficient construction: The breakwater designed in the present invention can be prefabricated in blocks and assembled on site, which is efficient in construction, easy to maintain, and cost-effective. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figures 1 to 6 As shown, the present invention provides a thin-film floating power generation breakwater, comprising a plurality of breakwater units 1 arranged in an array. The breakwater units 1 include pontoons 2. The pontoons 2 are rectangular box structures composed of a front plate 9, a rear plate 10, a bottom plate 8, a top plate 7, and two side plates 11. The two larger surfaces are arranged parallel to the still water surface, i.e., the bottom plate 8 and the top plate 7 are arranged parallel to the still water surface, the side plates 11 are arranged parallel to the wave direction, and the front plate 9 is the side facing the waves. A mooring system 6 is respectively arranged at the four prisms of the pontoon 2 perpendicular to the still water surface. The mooring system 6 includes a chain link 40, an anchor chain 42, and an anchor block 43. The four prisms of the pontoon 2 perpendicular to the still water surface are the intersections of the front plate 9, the rear plate 10, and the two side plates 11. The chain link 40 is used to connect the plurality of breakwater units 1 together in pairs, thereby enhancing the stability of the entire breakwater system. The chain clasp 40 fastens the two breakwater units 1 together through pre-reserved holes b13 defined in the four prisms of the pontoon 2, perpendicular to the still water surface. Pre-reserved holes b13 are defined in corresponding locations on the front plate 9, rear plate 10, and both side plates 11. Anchor blocks 43 are positioned underwater, with the ends of the anchor chain 42 fixedly connected to the pontoon 2 and anchor blocks 43, respectively. The bottom plate 8 is positioned adjacent to the anchor blocks 43, while the top plate 7 is positioned distally.

[0038] A plurality of reserved holes a12 are provided around the top plate 7, and a frame 3 is provided above the top plate 7. The frame 3 can be in several layers, and the first layer is connected to the pontoon 2. Each layer of the frame 3 includes a horizontal rod 14, a vertical rod 15 and a connecting block a16. The horizontal rod 14 is arranged parallel to the still water surface and connected head to tail to form a square; the vertical rod 15 is arranged perpendicular to the still water surface to support the horizontal rod 14. The frames 3 or the frame 3 and the pontoon 2 are fixedly connected by connecting blocks a16. The number of the reserved holes a12 is consistent with the number of the vertical rods 15 of the first layer of the frame 3. The vertical rods 15 of the first layer of the frame 3 are inserted into the reserved holes a12 and fixedly connected to the top plate 7 of the pontoon 2 through the connecting blocks a16.

[0039] The breakwater unit 1 also includes a membrane 4 and a power generation system 5. The number of membrane layers 4 matches the number of layers in the frame 3. The membrane 4 is connected at both ends to two horizontal rods 14, perpendicular to the wave direction. The power generation system 5 comprises a floating plate 17, a connecting block b18, connecting rods a19, and connecting rods b20, arranged within the frame 3. It also includes a motor system, a support rod 28, a speed-increasing gear 29, upper gear teeth 30, lower gear teeth 31, a stator 33, a generator box 34, a running slot 35, and a generator 37, arranged within the pontoon 2. The support rod 28 is arranged parallel to the wave direction, with its ends connected to the front plate 9 and rear plate 10, respectively. The support rod 28 is positioned midway along the height of the pontoon 2 and near the side plates 11. There are two support rods 28, symmetrically arranged about the centerline of the pontoon 2, which is parallel to the wave direction. The generator box 34 is located in the middle of the pontoon 2, and houses a stator 33. The motor system is arranged perpendicular to the wave direction, passes through the generator box 34, and is slidably connected to the support rod 28 at both ends. The sidewalls of the generator box 34 are provided with a travel gap 35 within the range of motion of the mover system. The coil is wound around the mover system. The connecting rod b20 is rotatably connected to the mover system at one end and to the connecting rod a19 at the other end. The connecting rod a19 is rotatably connected to the connecting block b18 at its other end and secured to the center of the float plate 17 via the connecting block b18. The float plate 17 is positioned in the center of the top membrane 4 and can be the same width as the top membrane 4. The float plate 17 is fixedly connected to the membrane 4 and positioned in the center of the membrane 4. There are two mover systems and two connecting rods b20, each symmetrically arranged about the centerline of the pontoon 2, perpendicular to the wave direction. Waves drive the membrane 4 and the float plate 17 up and down, thereby driving the connecting rod a19 up and down, changing the angle between the connecting rod b20 and the pontoon 2. The connecting rod b20 drives the mover system back and forth in the direction of the waves, ultimately causing the mover system to cut through the magnetic flux lines within the generator box 34 to generate electricity.

[0040] The movable subsystem includes a shaft a21, a shaft b22, a gear a23, a gear b24, a gear c25, a gear d26, a connecting rod c27, and a permanent magnet 32. The shaft a21 is arranged perpendicular to the wave direction, and its two ends are slidably connected to two support rods 28, and the shaft a21 can slide on the support rods 28. The shaft b22 is parallel to the shaft a21, and the shaft b22 does not contact the support rods 28. A gear a23 is sleeved on both sides of the shaft a21 near the support rods 28, and the two gears a23 are symmetrically arranged relative to the center line of the buoyancy tank 2 parallel to the wave direction. Gears b24 and gear c25 are fixedly connected on both sides of the shaft b22. On one side of the shaft a21 and shaft b22, gear a23 is meshed with gear b24 and the wheelbase is connected by a connecting rod c27. The connecting rod c27 is fixedly connected at the gear a23 and rotatably connected at the gear b24. On the other side of shafts a21 and b22, gear a23 meshes with gear d26, which in turn meshes with gear c25. Gears a23, d26, and c25 drive in parallel, and their wheelbases are also connected by connecting rod c27. Connecting rod c27 is fixedly connected at gears a23 and d26 and rotatably connected at gear c25. Gears a23 and d26 can rotate about their respective axes, while gears b24 and c25 can drive shaft b22 to rotate along with them. Shaft b22 is also provided with a speed-increasing gear 29, which is also connected to a generator 37. The speed-increasing gear 29 rotates with shaft b22, driving the generator 37 to generate electricity. The speed-increasing gear 29 is preferably located on the side of gear c25 away from the side plate 11. Two rows of upper gear teeth 30 are arranged on the half of the top plate 7 near the front plate 9. These two rows of upper gear teeth 30 mesh with the two gears a23 on that side. Two rows of lower gear teeth 31 are arranged on the half of the bottom plate 8 near the rear plate 10. These two rows of lower gear teeth 31 mesh with the two gears a23 on that side. One end of the connecting rod b20 is rotatably connected to the middle of the shaft a21, and the other end is rotatably connected to the connecting rod a19. Permanent magnets 32 are arranged around the shafts a21 and b22, and coils are wound around the permanent magnets 32. Two horizontal travel slots 35 are provided on the wall of the generator box 34 to allow for the movement of the shafts a21 and b22.

[0041] The length of the side plate 11 is equal to the length L of the breakwater unit 1, the length of the front plate 9 is equal to the width B of the breakwater unit 1, and the total height of the pontoon 2 and the frame 3 is equal to the height H of the breakwater unit 1. The ratio of the length L of the breakwater unit 1 to the incident wavelength is greater than 0.25, the height H is approximately the wave height + 2m, and the width B is approximately 1 / 2 of the incident wavelength. In the film 4, the top film 4 is divided into two pieces by the floating plate 17, and the length of each top film is M. 顶 To meet: That is, it does not affect the heaving motion of the floating plate 17. Here, N is the length of the floating plate 17 along the wave direction. In the aforementioned film 4, except for the top film 4, the length M of each layer of film 4 must satisfy 1.2L ≥ M > L. Holes 39 are defined in the center of each layer. The size of these holes 39 is determined based on the range of motion of the connecting rods a19 and b20, ensuring that the connecting rods a19 and b20 do not contact the film 4. The interlayer spacing of the aforementioned film 4 is 0.1-0.3 times the height H.

[0042] The length M of the connecting rod a19 杆a To meet: Where A is the height of the buoyancy tank 2. The length of the connecting rod b20 is M 杆b To satisfy both: and Where D is the minimum horizontal distance from the shaft a21 to the front plate 9, and R is the radius of the gear a23.

[0043] The film 4 is made of high-strength film material, and can be made of glass fiber synthetic material, etc. The frame 3, connecting rod a19, and connecting rod b20 can be made of corrosion-resistant steel.

[0044] like Figures 2 to 3 As shown, a damping plate 38 is provided in the middle of the top plate 7 to prevent or mitigate the impact of the connecting rod a19 on the top plate 7. Two sealing seams 36 are symmetrically provided on the top plate 7 at both ends of the damping plate 38, based on the range of movement of the connecting rod b20, to prevent seawater from entering the pontoon 2. The sealing process is conventional and will not be described in detail here. The sealing seams 36 are provided along the wave direction.

[0045] The length N of the floating plate 17 along the wave direction can be larger, which can reduce the displacement amplitude of the connecting rod a19 and the connecting rod b20 and enhance the wave-breaking effect.

[0046] like Figures 5 to 6 As shown, the tips of the upper teeth 30 on the gear b24 are tilted toward the front plate 9, while the tips of the lower teeth 31 are tilted toward the rear plate 10. The tips of the upper teeth 30 on the gear c25 are tilted toward the rear plate 10, while the tips of the lower teeth 31 are tilted toward the front plate 9. The upper teeth 30, lower teeth 31, and the teeth of gear a23 are all soft-toothed, one-way gears and do not transmit power in the non-meshing direction.

[0047] The length of each row of upper and lower gear teeth 30 and 31 is designed to prevent collision between two gears a23 on the same support rod 28, and to prevent collision between gears b24 and c25 and the front plate 9 and rear plate 10. The tooth height of the upper and lower gear teeth 30 and 31 can be increased to reduce the dimensions of gears a23, b24, c25, and d26, allowing the power generation system 5 to fully operate within the wave height range and thereby increase power generation.

[0048] like Figures 7 to 10 As shown, the rotational connections between the connecting rod c27 and the shaft b22, between the connecting rod b20 and the shaft a21, between the connecting rod a19 and the connecting rod b20, and between the connecting block b18 and the connecting rod a19 can all be achieved by providing a bearing 41.

[0049] The present invention also provides a method for using an assembled thin-film floating power generation breakwater, the specific steps of which are as follows:

[0050] Step 1: Arrange and combine multiple breakwater units 1 according to actual wave protection needs, so that the front plate 9 is on the wave-facing side, and connect them through chain links 40 to form a whole breakwater.

[0051] Step 2: Prefabricate the pontoon 2 of the breakwater unit 1 and its internal components (including the connecting rod b20 extending from the pontoon 2), each layer of frame 3, and each layer of membrane 4 (the top membrane includes the floating plate 17), assemble them layer by layer at the construction site, and finally connect the connecting rod a19 to the connecting rod b20 and the floating plate 17.

[0052] Step 3: Place the breakwater unit 1 in the water so that the top of the frame 3 is flush with the still water surface. Under the action of waves, when the floating plate 17 rises, the two connecting rods b20 will respectively pull the two shafts a21 to move toward the middle of the pontoon 2. The gear a23 on the side of the gear c25 will rotate counterclockwise, which will drive the gear c25 to rotate counterclockwise through the gear d26. The shaft b22 and the speed-increasing gear 29 will rotate counterclockwise at the same time, thereby driving the generator 37 to generate electricity. At this time, there is no transmission between the gear a23 and the gear b24. When the floating plate 17 descends, the two connecting rods b20 will respectively push the two shafts a21 to move toward the front and rear ends of the pontoon 2. The gear a23 on the side of the gear b24 will rotate clockwise, which will drive the gear b24 to rotate counterclockwise. The shaft b22 and the speed-increasing gear 29 will rotate counterclockwise at the same time, thereby driving the generator 37 to generate electricity. At this time, there is no transmission between the gear a23 and the gear d26.

[0053] Step 4: When shaft a21 and shaft b22 move horizontally back and forth in the generator box 34, they cut the magnetic lines of force to generate electricity.

[0054] In addition to the above embodiments, the present invention may also have other implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
