Description

Technical Field

[0001] This application relates to the technical field of breakwaters, and in particular to a box-type foundation breakwater structure, its working method, and its installation method. Background Technology

[0002] Wave energy is one of the most widely studied marine energy sources worldwide. Based on surveys and calculations using wave observation data, the theoretical average power of wave energy resources along my country's coast is 12.85 million kW, indicating broad development prospects and the potential to provide renewable and clean energy for my country's coastal cities. Compared to other marine energy development methods, wave energy power generation has advantages such as simple energy conversion principles, convenient construction and maintenance, and suitability for large-scale, intensive development. Breakwaters, constructed by combining cylindrical foundations with box-type breakwater structures, have been widely used, serving both wave protection and wave energy generation functions.

[0003] A search revealed Chinese Patent Publication No. CN102155000A, which discloses a breakwater capable of generating electricity using waves. The breakwater has a water-storage structure on its water-facing side. This structure includes two side walls fixed to the breakwater, with the bottoms of these side walls fixed to a reinforced concrete cover plate. Inclined, fixed front baffles are mounted on the side walls, with their bottoms also fixed to the reinforced concrete cover plate. The reinforced concrete cover plate, the two side walls, the breakwater, and the fixed front baffles form a water storage tank. A supporting frame for the water storage structure is located within the tank. A drainage channel, connected to the water storage tank, runs through the breakwater. A hydroelectric generator is installed within the drainage channel. This invention combines wave protection with wave power generation, exhibiting structural stability and high energy conversion efficiency, thus optimizing the breakwater structure.

[0004] The aforementioned technologies have the following drawbacks: the breakwater mainly focuses on safety protection and is relatively weak in the recovery and utilization of wave energy. Moreover, the recovery and utilization method is singular, that is, it only generates electricity by having waves surge into the hydroelectric generator unit, resulting in a large amount of energy loss. The wave energy recovery and utilization rate is not high and the power generation efficiency is poor. Therefore, improvements are needed. Summary of the Invention

[0005] In order to improve the recovery and utilization rate of wave energy and thus improve the power generation efficiency of wave energy, this application provides a box-type foundation breakwater structure, its working method and installation method.

[0006] In the first aspect, the present application provides a box-type foundation breakwater structure, which adopts the following technical solution: a box-type foundation breakwater structure, including a front row of power generation towers and a rear row of power generation towers arranged at intervals.

[0007] The front row of power generation towers is equipped with a front guide pipe and a horizontal front elastic unit. The front guide pipe allows waves to surge in to cause the front row of power generation towers to generate electricity, and the horizontal front elastic unit allows waves to pound on the front row of power generation towers to generate electricity.

[0008] The rear power generation tower is equipped with a rear guide pipe that is higher than the front power generation tower and a horizontal rear elastic unit. The rear guide pipe allows waves that have passed over the front power generation tower to surge in and cause the rear power generation tower to generate electricity. The horizontal rear elastic unit allows waves that have passed over the front power generation tower to beat against it and cause the rear power generation tower to generate electricity.

[0009] The rear power generation tower is equipped with a water guide pipe located below the rear guide pipe. There are two impellers in the rear power generation tower, which are respectively located inside the rear guide pipe and the water guide pipe. Both ends of the water guide pipe are open and are located on the front and rear sides of the rear power generation tower. The front side wall of the water guide pipe is connected to the front branch pipe. The front end of the front branch pipe is located at the rear end of the front guide pipe and is coaxial with the front guide pipe. There are two sets of horizontal front elastic units, which are located at the front and rear ends of the front power generation tower, and there are two sets of horizontal rear elastic units, which are located at the front and rear ends of the rear power generation tower.

[0010] At least one vertical front elastic unit is provided at both ends of the front row of power generation towers. The impeller main shaft in the front row of power generation towers is connected to the vertical front elastic unit through the vertical front transmission unit. When the vertical front elastic unit is deformed by wave impact, it will drive the impeller main shaft in the front row of power generation towers to rotate through the vertical front transmission unit.

[0011] The vertical front elastic unit includes a buoyancy plate that can only move up and down. One end of the buoyancy plate extends to the outside of the front row of power generation towers. Both the upper and lower sides of the buoyancy plate are connected to the slide grooves set on the side of the front row of power generation towers by connecting springs, so that the buoyancy plate is in the middle of the slide groove when it is not under force.

[0012] The vertical front transmission unit includes a rotating rod that can flip in a vertical plane. One end of the rotating rod is rotatably connected to a buoyancy plate, and the other end of the rotating rod is rotatably connected to a push rod that can only move along its own axis. The sliding direction of the push rod is located in the flipping plane of the rotating rod. A drive plate is mounted on the push rod, and several meshing teeth are mounted on the drive plate. A second gear for meshing teeth to engage is fixedly sleeved on the impeller main shaft of the front row of power generation towers.

[0013] At least one vertical rear elastic unit is provided at both the front and rear ends of the rear power generation tower. The impeller main shaft in the rear power generation tower is connected to the vertical rear elastic unit through the vertical rear transmission unit. When the vertical rear elastic unit is deformed by wave impact, it will drive the impeller main shaft in the rear power generation tower to rotate through the vertical rear transmission unit.

[0014] The connection structure between the vertical rear drive unit and the rear row of power generation towers is the same as the connection structure between the vertical front drive unit and the front row of power generation towers. The connection structure between the vertical rear elastic unit and the vertical rear drive unit is the same as the connection structure between the vertical front elastic unit and the vertical front drive unit.

[0015] Optionally, the impeller in the front row of the power generation tower is located inside the front guide pipe. When the horizontal front elastic unit is deformed by the wave impact, it will drive the main shaft of the impeller in the front row of the power generation tower to rotate through the horizontal front transmission unit. After the wave surges into the front guide pipe, it will push the impeller in the front row of the power generation tower to rotate. During the rotation of the impeller in the front row of the power generation tower, it will cause the generator in the front row of the power generation tower to generate electricity.

[0016] The horizontal front elastic unit includes two buffer shells installed on the front row of power generation towers. The two buffer shells are arranged vertically and spaced apart. The same buffer plate is slidably embedded in the two buffer shells along the front-back direction. The buffer plate is connected to the buffer shell by a buffer spring extending along the front-back direction. A buffer pad is installed at the front end of the buffer plate.

[0017] The horizontal front drive unit includes at least one mounting base installed at the rear end of the buffer plate. An elastic telescopic rod extending in the front-rear direction is installed at the rear end of the mounting base. A rack extending in the front-rear direction is installed at the rear end of the elastic telescopic rod. A first gear for meshing with the rack is fixedly sleeved on the impeller main shaft of the front row of power generation towers.

[0018] Optionally, the impeller in the rear power generation tower is located inside the rear guide pipe. When the horizontal rear elastic unit is deformed by the wave impact, it will drive the main shaft of the impeller in the rear power generation tower to rotate through the horizontal rear transmission unit. After the wave surges into the rear guide pipe, it will push the impeller in the rear power generation tower to rotate. During the rotation of the impeller in the rear power generation tower, it will cause the generator in the rear power generation tower to generate electricity.

[0019] The connection structure of the horizontal rear elastic unit and the horizontal rear transmission unit is the same as that of the horizontal front elastic unit and the horizontal front transmission unit. The connection structure of the horizontal rear transmission unit and the rear row of power generation towers is the same as that of the horizontal front transmission unit and the front row of power generation towers.

[0020] Secondly, this application provides a working method for a box-type foundation breakwater structure, employing the following technical solution: A working method for a box-type foundation breakwater structure includes the following working conditions.

[0021] When the front row of waves is low-level, meaning the front wave does not exceed the top of the front power generation tower, the breakwater structure will implement method A, which is as follows:

[0022] The waves will strike the horizontal front elastic unit on the front side and surge into the front guide pipe. When the waves hit the front row of power generation towers, they will overturn and strike the vertical front elastic unit on the front side. After the waves hit the rear row of tanks and generate reflected waves, they will strike the horizontal front elastic unit and the vertical front elastic unit on the rear side. Some of the waves that surge into the front guide pipe will flow into the water guide pipe through the front branch pipe. The waves that surge between the front row of power generation towers and the rear row of power generation towers will flow back through the front guide pipe.

[0023] Optionally, when the water level is high and the front waves can directly impact the side of the rear power generation towers, the breakwater structure will implement methods A and B, with method B as follows:

[0024] The waves will crash against the horizontal rear elastic unit on the front side and the vertical front elastic units on both sides, and surge into the water guide pipe and the rear guide pipe. When the waves hit the rear row of power generation towers, they will overturn and impact the vertical rear elastic units on the front side. Some of the waves that surge into the rear of the rear row of power generation towers will flow back through the water guide pipe and the rear guide pipe, and some of the waves that surge into the rear of the rear row of power generation towers will also impact the horizontal rear elastic unit and the vertical rear elastic unit on the rear side.

[0025] Optionally, when the front row of high-level waves surges, i.e., when the front row of waves can overturn the rear row of power generation towers, the breakwater structure will execute methods A, B, and C, with method C as follows:

[0026] The waves will roll over the rear row of power generation towers and directly impact the vertical rear elastic unit and the horizontal rear elastic unit on the rear side.

[0027] Optionally, when the downstream surges with low-level waves, i.e., the downstream waves do not exceed the guide pipe, the breakwater structure will execute method D, which is as follows:

[0028] Waves will surge into the water guide pipe and be discharged between the front and rear power generation towers through the water guide pipe and the front branch pipe. Waves between the front and rear power generation towers will impact the rear vertical front elastic unit and the rear horizontal front elastic unit and surge into the front guide pipe.

[0029] Optionally, when the water level in the rear surge is high, i.e., the rear wave does not exceed the top of the rear power generation tower, the breakwater structure will implement methods D and E, with method E as follows:

[0030] Waves will surge into the rear guide pipe and strike the rear horizontal elastic unit. Waves in the rear guide pipe will be discharged between the front and rear power generation towers and collide with the rear vertical front elastic unit and the rear horizontal front elastic unit. When the waves collide with the rear power generation tower, they will overturn and collide with the rear vertical elastic unit. Some waves surging to the front of the front power generation tower will collide with the front horizontal and vertical front elastic units and flow back through the front guide pipe.

[0031] Optionally, when high-level waves surge in the rear section, i.e., when the rear waves can overturn the rear power generation tower, the breakwater structure will execute methods D, E, and F, with method F as follows:

[0032] Some waves will overturn the rear row of power generation towers and directly impact the horizontal front elastic units on both sides, the vertical front elastic units on both sides, the horizontal rear elastic unit on the front side, and the vertical rear elastic unit on the front side. Waves surging between the front and rear rows of power generation towers will flow to the front of the front row of power generation towers through the front guide pipe.

[0033] Thirdly, this application provides an installation method for a box-type foundation breakwater structure, which adopts the following technical solution: An installation method for a box-type foundation breakwater structure includes the following steps.

[0034] S1. Front row pre-installation: First, pour the front row box cylinder, then pour the front row platform plate on the upper surface of the front row box cylinder, and then pour and install the front row power generation tower on the upper surface of the front row platform plate to form the front row breakwater.

[0035] S2, Front row installation: The front row of breakwaters is transported by hovercraft, the air in the front row tank is extracted, and then the front row tank is inserted into the riverbed;

[0036] S3. Front reinforcement: First, a solidified compaction layer is laid on the riverbed, then a solidified leveling layer is laid on the surface of the solidified compaction layer, then the connecting reinforcement is inserted into the front platform plate, and then quick-setting cement is laid on the surface of the solidified leveling layer, so that the two ends of the connecting reinforcement are respectively located in the front platform plate and in the quick-setting cement.

[0037] S4. Rear foundation installation: First, pour the rear box cylinder, then remove the air from the rear box cylinder and insert it into the riverbed, tightly against the rear side wall of the front platform plate. Then, pour the rockfill dam foundation and insert it into the riverbed, tightly against the rear side wall of the rear box cylinder. After that, install the load-bearing rockfill dam on the upper surface of the rockfill dam foundation and the rear side wall of the rear box cylinder, making the upper surface of the load-bearing rockfill dam flush with the upper surface of the rear box cylinder. Then, pour the rear platform plate on the upper surface of the rear box cylinder and the upper surface of the load-bearing rockfill dam, and then install the water guide pipe on the upper surface of the rear platform plate.

[0038] S5. Water level regulation: Regulate the water level on the front, middle and rear sides of the breakwater to form a state where the rear side is the highest, the middle side is the second highest, and the front side is the lowest.

[0039] S6. Rear row installation: The rear row power generation tower is cast and installed on the upper surface of the rear row platform to form the rear row breakwater.

[0040] In summary, this application includes the following beneficial technical effects:

[0041] During the surge of waves, the waves will directly impact or backflow into the horizontal front and rear elastic units, as well as vertically impact the vertical front and rear elastic units. They will also directly or indirectly flow into the front guide pipe, rear guide pipe, and water guide pipe, enabling the front and rear power generation towers to generate electricity in multiple ways, thereby improving the recovery and utilization rate of wave energy and thus improving the power generation efficiency of wave energy.

[0042] This application improves the safety protection effect by combining the front and rear breakwaters to allow waves to be dissipated multiple times.

[0043] Both the front and rear breakwaters are inserted into the riverbed using cascade tubes, which further enhances the stability of the breakwaters.

[0044] In areas with water level differences, this application can be directly installed at the water level difference, enabling it to generate electricity through the water level difference;

[0045] When waves of different levels surge in from the front or rear, this application can use different methods to generate electricity in various ways, thereby making full use of wave energy and improving the power generation efficiency of wave energy. Attached Figure Description

Detailed Implementation

[0063] The following is in conjunction with the appendix Figure 1-16 This application will be described in further detail.

[0064] This application discloses a box-type foundation breakwater structure. For example... Figure 1As shown, a box-type foundation breakwater structure includes a front row of power generation towers 1 and a rear row of power generation towers 2 arranged at intervals. The front row of power generation towers 1 can withstand the direct impact of waves to perform primary energy dissipation. An eddy current deceleration zone is formed between the front row of power generation towers 1 and the rear row of power generation towers 2 to perform secondary energy dissipation. The rear row of power generation towers 2 disperses the residual wave impact force to perform tertiary energy dissipation.

[0065] A front platform plate 11 is installed on the lower surface of the front power generation tower 1. A reinforcing slope 12 is installed at the front end of the front platform plate 11. The reinforcing slope 12 connects the riverbed and the front platform plate 11. Several front box cylinders 13 are installed on the lower surface of the front platform plate 11. The front box cylinders 13 are inserted into the riverbed as a whole, thus forming a front breakwater.

[0066] A rear platform plate 21 is installed on the lower surface of the rear power generation tower 2. Several rear box cylinders 22 and a load-bearing rockfill dam 23 are installed on the lower surface of the rear platform plate 21. The rear box cylinders 22 are installed close to the rear side wall of the front platform plate 11, and the lower end of the rear box cylinders 22 is inserted into the riverbed. The load-bearing rockfill dam 23 is installed close to the rear side wall of the rear box cylinders 22. A rockfill dam foundation 24 is installed on the lower surface of the load-bearing rockfill dam 23. The rockfill dam foundation 24 is inserted into the riverbed as a whole and installed close to the rear side wall of the rear box cylinders 22, thus forming a rear breakwater.

[0067] Compared to existing technologies, this application improves the safety protection effect by using a combination of front and rear breakwaters to dissipate wave energy multiple times; and both the front and rear breakwaters are inserted into the riverbed through box-shaped tubes, thereby improving the stability of the breakwaters.

[0068] A horizontally positioned front guide pipe 14 is installed in the middle of the front generation tower 1. Both ends of the front guide pipe 14 are open, and the front guide pipe 14 passes through the front generation tower 1. The impeller in the front generation tower 1 is located inside the front guide pipe 14. When the front wave surges in, the wave will surge into the front guide pipe 14 and drive the impeller in the front generation tower 1 to rotate. The impeller in the front generation tower 1 will drive the generator in the front generation tower 1 to generate electricity.

[0069] Since the overall height of the rear generation tower 2 is greater than that of the front generation tower 1, the waves discharged from the rear end of the front guide pipe 14 will directly impact the rear casing 22. Some of the waves will be reflected back to form reflected waves, and some of the reflected waves will flow back into the front guide pipe 14 and drive the impeller in the front generation tower 1 to rotate, thereby enabling the generator to generate electricity again.

[0070] It is worth noting that since the waves come in waves, as long as the distance between the front row of power generation tower 1 and the rear row of power generation tower 2 is controlled, the reflected waves can flow back in the front guide pipe 14 during the intervals between the two waves, thus minimizing the impact and energy dissipation of the waves in the front guide pipe 14 and making full use of the wave energy.

[0071] In addition, when the waves surge, creating a water level difference between the front and rear of the front power generation tower 1, the water will flow through the front guide pipe 14 due to its own gravity, thereby prompting the front power generation tower 1 to generate electricity.

[0072] like Figure 2 As shown, a horizontal front elastic unit 3 is provided on the front side of the front row of power generation tower 1, and the impeller in the front row of power generation tower 1 is connected to the horizontal front elastic unit 3 through the horizontal front transmission unit.

[0073] The horizontal front elastic unit 3 includes two buffer shells 31 installed on the front row of power generation towers 1. The two buffer shells 31 are arranged vertically and horizontally. The same buffer plate 32 is slidably embedded in the two buffer shells 31 along the front-back direction. The buffer plate 32 is connected to the buffer shell 31 by a buffer spring 34 extending along the front-back direction. A buffer pad 33 is installed at the front end of the buffer plate 32.

[0074] The horizontal front drive unit includes at least one mounting base 35 installed at the rear end of the buffer plate 32. An elastic telescopic rod 36 extending in the front-rear direction is installed at the rear end of the mounting base 35. A rack 37 extending in the front-rear direction is installed at the rear end of the elastic telescopic rod 36. A first gear 38 is fixedly sleeved on the impeller main shaft of the front row of power generation tower 1.

[0075] When the wave does not impact the horizontal front elastic unit 3, the buffer spring 34 will be in its natural state. At this time, the rack 37 is not engaged with the first gear 38, so that the horizontal front elastic unit 3 will not affect the wave in the front guide pipe 14 to drive the impeller to rotate.

[0076] When the wave impacts the buffer pad 33, the buffer plate 32 will move backward and push the rack 37 to move through the mounting base 35 and the elastic telescopic rod 36. The rack 37 will mesh with the first gear 38 and drive the impeller main shaft to rotate through the first gear 38. The impeller main shaft will drive the generator to generate electricity.

[0077] In addition, during the process of the buffer pad 33 being impacted by waves, the buffer spring 34 will be gradually compressed and generate energy dissipation, so that the buffer plate 32 will not have a rigid collision with the front row of power generation tower 1.

[0078] It is worth noting that both the buffer pad 33 and the buffer plate 32 are provided with through holes 321, which correspond to the end opening of the front guide pipe 14, so that the buffer pad 33 and the buffer plate 32 will not affect the wave flow into the front guide pipe 14.

[0079] In this embodiment, there are two sets of horizontal front elastic units 3, which are respectively located at the front and rear ends of the front row of power generation towers 1. The reflected waves between the front row of power generation towers 1 and the rear row of power generation towers 2 will strike the rear horizontal front elastic unit 3, causing the impeller main shaft to rotate and drive the generator to generate electricity.

[0080] It is worth noting that the racks 37 in the two sets of horizontal front elastic units 3 are arranged in an alternating manner, so that the racks 37 in the two sets of horizontal front elastic units 3 will not have rigid collisions.

[0081] At least one vertical front elastic unit 4 is provided at both the front and rear ends of the front row power generation tower 1. The impeller main shaft in the front row power generation tower 1 is connected to the vertical front elastic unit 4 through the vertical front transmission unit 5.

[0082] The vertical front elastic unit 4 includes a buoyancy plate 41 arranged horizontally. The side of the front row power generation tower 1 is provided with a sliding groove 42 for the buoyancy plate 41 to slide through in the vertical direction. One end of the buoyancy plate 41 extends to the outside of the front row power generation tower 1, and the other end of the buoyancy plate 41 extends into the inside of the front row power generation tower 1.

[0083] Multiple vertically arranged limiting posts 43 are installed inside the chute 42. The limiting posts 43 slide through the buoyancy plate 41, so that the buoyancy plate 41 can only move up and down. The upper and lower sides of the buoyancy plate 41 are connected to the chute wall of the chute 42 by connecting springs 44, so that the buoyancy plate 41 is in the middle of the chute 42 when it is not under force.

[0084] Both the upper and lower sides of the buoyancy plate 41 are connected to the groove wall of the chute 42 by folding blades 45. The folding blades 45 can block the waves and prevent the waves from rushing into the front row of power generation towers 1.

[0085] The vertical front transmission unit 5 includes a rotating rod 51 that can flip in a vertical plane. One end of the rotating rod 51 is rotatably connected to the end of the buoyancy plate 41 that extends into the inner side of the front row of power generation towers 1. The other end of the rotating rod 51 is rotatably connected to a push rod 52. A limiting cylinder 53 is slidably sleeved on the push rod 52. The limiting cylinder 53 is fixedly installed inside the front row of power generation towers 1, so that the push rod 52 can only move along its own axis, and the sliding direction of the push rod 52 is located in the flipping plane of the rotating rod 51. A drive plate 54 is installed on the push rod 52, and several meshing teeth 55 are installed on the drive plate 54. A second gear 56 is fixedly sleeved on the impeller main shaft of the front row of power generation towers 1.

[0086] When the buoyancy plate 41 is not under force, the meshing teeth 55 will not mesh with the second gear 56, and the meshing teeth 55 will be distributed on the front and rear sides of the second gear 56, so that the vertical front elastic unit 4 will not affect the rotation of the impeller main shaft.

[0087] When the waves surge to the front row of power generation tower 1, the buoyancy of the water, the upward impact of the waves on the buoyancy plate 41, and the downward impact of the waves on the buoyancy plate 41 will all cause the buoyancy plate 41 to move in the vertical direction. The buoyancy plate 41 will drive the push rod 52 to move through the rotating rod 51. The push rod 52 will cause the meshing teeth 55 on the drive plate 54 to mesh with the second gear 56. The second gear 56 will drive the impeller main shaft inside the front row of power generation tower 1 to rotate, so that the generator of the front row of power generation tower 1 generates electricity.

[0088] In this embodiment, vertical front elastic units 4 are provided at both the front and rear ends of the front power generation tower 1. The drive plates 54 in the two sets of vertical front elastic units 4 are arranged in an alternating manner, so that the drive plates 54 in the two sets of vertical front elastic units 4 will not have a rigid collision.

[0089] like Figure 3 As shown, a horizontally arranged rear guide pipe 25 is installed in the middle of the rear power generation tower 2. Both ends of the rear guide pipe 25 are open and it runs through the rear power generation tower 2. The impeller in the rear power generation tower 2 is located inside the rear guide pipe 25. When the front wave surges in, because the overall height of the rear power generation tower 2 is greater than that of the front power generation tower 1, and the height of the rear guide pipe 25 is higher than that of the front guide pipe 14 and the horizontal front elastic unit 3, the wave at the middle water level can directly surge into the rear guide pipe 25 and drive the impeller in the rear power generation tower 2 to rotate. The impeller in the rear power generation tower 2 will drive the generator in the rear power generation tower 2 to generate electricity.

[0090] The rear power generation tower 2 is equipped with a horizontal rear elastic unit 6. The impeller main shaft in the rear power generation tower 2 is connected to the horizontal rear elastic unit 6 through the horizontal rear transmission unit. The height of the horizontal rear elastic unit 6 is higher than that of the front guide pipe 14 and the front elastic unit.

[0091] The connection structure between the horizontal rear elastic unit 6 and the horizontal rear transmission unit is the same as that between the horizontal front elastic unit 3 and the horizontal front transmission unit. The connection structure between the horizontal rear transmission unit and the rear generation tower 2 is the same as that between the horizontal front transmission unit and the front generation tower 1. Therefore, when the wave impacts the horizontal rear elastic unit 6, the horizontal rear elastic unit 6 will drive the impeller main shaft of the rear generation tower 2 to rotate through the horizontal rear transmission unit, and the impeller main shaft will drive the generator to generate electricity.

[0092] In this embodiment, there are two sets of horizontal rear elastic units 6, which are respectively located at the front and rear ends of the rear power generation tower 2. When the waves surge from the rear to the front, the waves will impact the horizontal rear elastic units 6 on the rear side of the rear power generation tower 2, so that the rear power generation tower 2 can still generate electricity.

[0093] At least one vertical rear elastic unit 7 is provided at both the front and rear ends of the rear power generation tower 2. The impeller in the rear power generation tower 2 is connected to the vertical rear elastic unit 7 through the vertical rear transmission unit 8. The connection structure between the vertical rear transmission unit 8 and the rear power generation tower 2 is the same as the connection structure between the vertical front transmission unit 5 and the front power generation tower 1. The connection structure between the vertical rear elastic unit 7 and the vertical rear transmission unit 8 is the same as the connection structure between the vertical front elastic unit 4 and the vertical front transmission unit 5.

[0094] When the waves surge to the rear power generation tower 2, the buoyancy of the water, the upward impact force of the waves, and the downward impact force of the waves will all cause the vertical rear elastic unit 7 to deform. The vertical rear elastic unit 7 will drive the impeller main shaft in the rear power generation tower 2 to rotate through the vertical rear transmission unit 8, and the impeller main shaft will drive the generator to generate electricity.

[0095] In this embodiment, vertical rear elastic units 7 are provided at both the front and rear ends of the rear power generation tower 2. The drive plates 54 in the two sets of vertical rear elastic units 7 are arranged in an alternating manner, so that the drive plates 54 in the two sets of vertical rear elastic units 7 will not have a rigid collision.

[0096] The lower end of the rear power generation tower 2 and the upper surface of the rear platform plate 21 are both equipped with the same water guide pipe 26 located below the rear guide pipe 25. The rear power generation tower 2 has two impellers, one inside the rear guide pipe 25 and the other inside the water guide pipe 26. Both ends of the water guide pipe 26 are open and located on the front and rear sides of the rear power generation tower 2, respectively. Waves surging in front and behind can flow into the water guide pipe 26, causing the impellers in the rear power generation tower 2 to rotate. The impellers then drive the generator to generate electricity.

[0097] It is worth noting that when the waves surge, creating a water level difference between the front and rear of the rear power generation tower 2, the water will flow through the water guide pipe 26 and the rear guide pipe 25 due to its own gravity, thereby causing the rear power generation tower 2 to generate electricity.

[0098] A front branch pipe 27 is connected to the front side wall of the water guide pipe 26. The front end of the front branch pipe 27 is located at the rear end of the front guide pipe 14 and is arranged coaxially with the front guide pipe 14.

[0099] When the waves surge into the front guide pipe 14, some of the waves discharged from the rear end of the front guide pipe 14 will surge into the water guide pipe 26 through the front branch pipe 27, causing the impeller in the rear power generation tower 2 to rotate, thereby causing the rear power generation tower 2 to generate electricity.

[0100] When the waves from the rear surge into the water guide pipe 26, some of the waves in the water guide pipe 26 can surge into the front guide pipe 14 through the front branch pipe 27, causing the impeller in the front row power generation tower 1 to rotate, thereby causing the front row power generation tower 1 to generate electricity.

[0101] The rear side wall of the water guide pipe 26 is connected to the rear branch pipe 28. Waves at the low water level behind can flow into the water guide pipe 26 through the rear branch pipe 28, causing the impeller in the rear power generation tower 2 to rotate, thereby causing the rear power generation tower 2 to generate electricity.

[0102] The implementation principle of a box-type foundation breakwater structure in this application embodiment is as follows: During the surging of waves, the waves will directly impact or backflow impact the horizontal front elastic unit 3 and the horizontal rear elastic unit 6, and will also vertically impact the vertical front elastic unit 4 and the vertical rear elastic unit 7. They will also directly or indirectly flow into the front guide pipe 14, the rear guide pipe 25 and the water guide pipe 26, so that the front row power generation tower 1 and the rear row power generation tower 2 can generate electricity in multiple forms, thereby improving the recovery and utilization rate of wave energy and thus improving the power generation efficiency of wave energy.

[0103] This application also discloses a working method for a box-type foundation breakwater structure. The working method for a box-type foundation breakwater structure includes the following operating conditions:

[0104] like Figure 4 As shown, when the front row of waves is low-level, meaning the front wave does not exceed the top of the front generation tower 1, the breakwater structure will execute method A, which is as follows:

[0105] The waves will strike the horizontal front elastic unit 3 on the front side and surge into the front guide pipe 14. When the waves hit the front row of power generation towers 1, they will overturn and strike the vertical front elastic unit 4 on the front side. After the waves hit the rear row of tanks 22 and generate reflected waves, they will strike the horizontal front elastic unit 3 and the vertical front elastic unit 4 on the rear side. Some of the waves that surge into the front guide pipe 14 will surge into the water guide pipe 26 through the front branch pipe 27. The waves that surge between the front row of power generation towers 1 and the rear row of power generation towers 2 will flow back through the front guide pipe 14.

[0106] The horizontal front elastic unit 3, the front guide pipe 14, the vertical front elastic unit 4, and the water guide pipe 26 work together to enable method A to generate electricity from the front row power generation tower 1 and the rear row power generation tower 2 through various means such as wave impact, wave flow, reflected wave impact, and wave backflow.

[0107] like Figure 5 As shown, when the water level is surging in the front row, meaning the front waves can directly impact the side of the rear power generation tower 2, the breakwater structure will execute methods A and B. Method B is as follows:

[0108] The waves will strike the front horizontal rear elastic unit 6 and the front and rear vertical front elastic units 4 on both sides and surge into the water guide pipe 26 and the rear guide pipe 25. When the waves hit the rear row power generation tower 2, they will overturn and strike the front vertical rear elastic unit 7. Some of the waves that surge into the rear of the rear row power generation tower 2 will flow back through the water guide pipe 26 and the rear guide pipe 25, and some of the waves that surge into the rear of the rear row power generation tower 2 will also strike the rear horizontal rear elastic unit 6 and the rear vertical rear elastic unit 7.

[0109] The vertical front elastic unit 4, the horizontal rear elastic unit 6, the water guide pipe 26, the rear guide pipe 25, and the vertical rear elastic unit 7 work together to enable method B to generate electricity from the front row power generation tower 1 and the rear row power generation tower 2 through various means such as wave impact, wave flow, reflected wave collision, and wave backflow.

[0110] like Figure 6 As shown, when the front row of high-level waves surges, meaning the front waves can overturn the rear generation tower 2, the breakwater structure will execute methods A, B, and C. Method C is as follows:

[0111] The wave will overturn the rear row of power generation towers 2 and directly impact the vertical rear elastic unit 7 and the horizontal rear elastic unit 6 on the rear side.

[0112] The vertical rear elastic unit 7 and the horizontal rear elastic unit 6 work together to enable method C to generate electricity from the rear power generation tower 2 by means of wave impact.

[0113] like Figure 7 As shown, when the downstream surges with low-level waves, i.e., the downstream waves are no higher than the guide pipe 26, the breakwater structure will execute method D, which is as follows:

[0114] Waves will surge into the water guide pipe 26 and be discharged through the water guide pipe 26 and the front branch pipe 27 to the space between the front row power generation tower 1 and the rear row power generation tower 2. Waves between the front row power generation tower 1 and the rear row power generation tower 2 will impact the rear vertical front elastic unit 4 and the rear horizontal front elastic unit 3 and surge into the front guide pipe 14.

[0115] The water guide pipe 26, the vertical front elastic unit 4, the horizontal front elastic unit 3 and the front guide pipe 14 work together to enable method D to generate electricity from the front row power generation tower 1 and the rear row power generation tower 2 through various means such as wave impact and wave flow.

[0116] like Figure 8 As shown, when the water level in the rear row is high, i.e., the rear row waves are not higher than the top of the rear row power generation tower 2, the breakwater structure will execute methods D and E. Method E is as follows:

[0117] Waves will surge into the rear guide pipe 25 and strike the rear horizontal elastic unit 6. Waves in the rear guide pipe 25 will be discharged between the front row power generation tower 1 and the rear row power generation tower 2 and collide with the rear vertical front elastic unit 4 and the rear horizontal front elastic unit 3. When the waves collide with the rear row power generation tower 2, they will overturn and collide with the rear vertical rear elastic unit 7. Some waves surging to the front of the front row power generation tower 1 will collide with the front horizontal front elastic unit 3 and the vertical front elastic unit 4 and flow back through the front guide pipe 14.

[0118] The front guide pipe 14, the rear guide pipe 25, the horizontal rear elastic unit 6, the vertical front elastic unit 4, the horizontal front elastic unit 3, and the vertical rear elastic unit 7 work together to enable method D to generate electricity from the front row power generation tower 1 and the rear row power generation tower 2 through various means such as wave pounding, wave flow, and wave impact.

[0119] like Figure 9 As shown, when high-level waves surge in the rear section, i.e., when the rear waves can overturn the rear power generation tower 2, the breakwater structure will execute methods D, E, and F. Method F is as follows:

[0120] Some waves will overturn the rear row of power generation towers 2 and directly impact the horizontal front elastic unit 3, the vertical front elastic unit 4, the horizontal rear elastic unit 6, and the vertical rear elastic unit 7 on the front sides. The waves surging between the front row of power generation towers 1 and the rear row of power generation towers 2 will flow to the front of the front row of power generation towers 1 through the front guide pipe 14.

[0121] The horizontal front elastic unit 3, the vertical front elastic unit 4, the horizontal rear elastic unit 6, the vertical rear elastic unit 7, and the front guide pipe 14 work together to enable method F to generate electricity from the front row power generation tower 1 and the rear row power generation tower 2 through various means such as wave impact and wave flow.
