Description

Technical Field

[0001] The present application relates to the technical field of wave-breaking and power generation, and in particular to a novel box-tube-type foundation breakwater structure, operation and installation method. Background Art

[0002] Wave energy is the most extensively researched form of marine energy 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, offering broad development prospects and the potential to provide renewable, clean energy for my country's coastal cities. Compared to other marine energy development methods, wave power generation offers the advantages of a simple energy conversion principle, easy construction and maintenance, and the potential for large-scale, intensive development. Breakwaters combining a barrel foundation with a box-and-barrel breakwater structure have been widely used, providing both wave protection and wave energy generation.

[0003] A search revealed Chinese patent publication number CN102155000A, which discloses a breakwater capable of generating electricity from waves. The breakwater is provided with a water storage structure on the waterfront side. The water storage structure comprises two side walls fixed to the breakwater, the bottoms of the two side walls being fixed to the reinforced concrete cover plate. The two side walls are provided with inclined fixed front baffles facing the waterfront, the bottoms of the fixed front baffles being 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 reservoir for the water storage structure, within which a support frame for the water storage structure is provided. A drainage channel is provided at the bottom of the breakwater, connecting to the water reservoir and extending through the breakwater. A hydroelectric generator set is installed within the drainage channel. This invention combines wave-breaking functions with wave-powered power generation, boasting structural stability and high energy conversion efficiency, achieving structural optimization for the breakwater.

[0004] The above-mentioned related technologies have the following defects: the breakwater mainly focuses on safety protection, and is relatively weak in the recovery and utilization of wave energy. The recovery and utilization method is single, that is, it only generates electricity by waves flowing into the hydropower generator set, 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, so it needs to be improved. 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, the present application provides a novel box-type foundation breakwater structure, working and installation method.

[0006] In a first aspect, the present application provides a novel box-tube type basic breakwater structure, which adopts the following technical solution: a novel box-tube type basic breakwater structure, comprising a front row of power generation towers and a rear row of power generation towers arranged in a front-to-back manner; The front row of power generation towers are provided with a front guide pipe and a horizontal front elastic unit. The front guide pipe allows waves to flow in to drive the front row of power generation towers to generate electricity, and the horizontal front elastic unit allows waves to hit the front row of power generation towers to generate electricity. The rear power towers are provided with rear guide pipes and horizontal rear elastic units which are higher than the front power towers. The rear guide pipes allow waves that pass over the front power towers to flow in to prompt the rear power towers to generate electricity. The horizontal rear elastic units allow waves that pass over the front power towers to hit to prompt the rear power towers to generate electricity.

[0007] Optionally, the impeller in the front row of power towers is located in the front guide pipe and is connected to the horizontal front elastic unit through the horizontal front transmission unit. When the horizontal front elastic unit is deformed by the impact of waves, it will drive the impeller in the front row of power towers to rotate through the horizontal front transmission unit. After the waves flow into the front guide pipe, they will push the impeller in the front row of power towers to rotate. During the rotation process, the impeller in the front row of power towers will prompt the generator in the front row of power towers to generate electricity.

[0008] Optionally, the impeller in the rear power tower is located in the rear guide tube and is connected to the horizontal rear elastic unit through the horizontal rear transmission unit. When the horizontal rear elastic unit is deformed by the impact of waves, it will drive the impeller in the rear power tower to rotate through the horizontal rear transmission unit. After the waves flow into the rear guide tube, they will push the impeller in the rear power tower to rotate. During the rotation process, the impeller in the rear power tower will prompt the generator in the rear power tower to generate electricity.

[0009] Optionally, the rear power generation tower is provided with a water guide pipe located below the rear guide pipe, and there are two impellers in the rear power generation tower, which are respectively arranged in the rear guide pipe and the water guide pipe; Both ends of the water pipe are open and are respectively arranged on the front and rear sides of the rear power tower. The front end side wall of the water 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 groups of horizontal front elastic units and they are respectively arranged at the front and rear ends of the front power generation tower; there are two groups of horizontal rear elastic units and they are respectively arranged at the front and rear ends of the rear power generation tower.

[0010] Optionally, a vertical front elastic unit is provided at least at one of the front and rear ends of the front power generation towers, and the impeller in the front power generation tower is connected to the vertical front elastic unit via a vertical front transmission unit. When the vertical front elastic unit is deformed by wave impact, it drives the impeller in the front power generation tower to rotate via the vertical front transmission unit. A vertical rear elastic unit is provided at least at the front and rear ends of the rear power generation tower. The impeller 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 in the rear power generation tower to rotate through the vertical rear transmission unit.

[0011] In the second aspect, the present application provides a novel working method of a box-tube type foundation breakwater structure, which adopts the following technical solution: A novel working method of a box-tube type foundation breakwater structure includes the following working conditions: When the front row surges with low water level waves, the breakwater structure will implement Method A, which is as follows: The waves will hit the horizontal front elastic unit on the front side and flow into the front guide pipe. When hitting objects, the waves will flip and hit the vertical front elastic unit and the horizontal front elastic unit on the rear side. Part of the waves flowing into the front guide pipe will flow into the water guide pipe through the front branch pipe, and the waves flowing between the front and rear power towers will flow back through the front guide pipe.

[0012] Optionally, when the front row surges with medium water level waves, the breakwater structure will execute Method A and Method B. Method B is as follows: The waves will hit the horizontal rear elastic unit and the vertical front elastic unit on the front side and flow into the water guide pipe and the rear guide pipe. When the waves hit the object, they will flip and hit the vertical rear elastic unit. Part of the waves that flow into the rear of the rear power tower will flow back through the water guide pipe and the rear guide pipe.

[0013] Optionally, when the front row surges with high water level waves, the breakwater structure will execute Method A, Method B and Method C. Method C is as follows: Some waves will roll over the rear row of power generation towers and directly hit the vertical rear elastic units and the rear horizontal rear elastic units.

[0014] Optionally, when the rear row surges low water level waves, the breakwater structure will implement method D, which is as follows: The waves will flow into the water guide pipe and be discharged between the front row of power towers and the rear row of power towers through the water guide pipe and the front branch pipe. The waves between the front row of power towers and the rear row of power towers will hit the vertical front elastic unit on the rear side and the horizontal front elastic unit on the rear side and flow into the front guide pipe.

[0015] Optionally, when the rear row surges with mid-water level waves, the breakwater structure will execute Method D and Method E. Method E is as follows: The waves will surge into the rear guide pipe and hit the horizontal rear elastic unit on the rear side. The waves in the rear guide pipe will be discharged between the front and rear power towers and hit the vertical front elastic units and the horizontal front elastic units on the rear side. When the waves hit the objects, they will flip and hit the vertical rear elastic units on the rear side. Part of the waves that surge to the front power towers will hit the horizontal front elastic units and vertical front elastic units on the front side and flow back through the front guide pipe.

[0016] Optionally, when there is a high water level wave in the rear row, the breakwater structure will implement Method D, Method E and Method F. The details of Method F are as follows: Part of the waves will roll over the rear row of power towers and directly hit the horizontal front elastic unit, vertical front elastic unit, horizontal rear elastic unit and vertical rear elastic unit. The waves surging between the front row of power towers and the rear row of power towers will flow through the front guide pipe to the front of the front row of power towers.

[0017] In a third aspect, the present application provides a novel method for installing a box-tube type foundation breakwater structure, which adopts the following technical solution: A novel method for installing a box-tube type foundation breakwater structure comprises the following steps: S1.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-16 This application is described in further detail.

[0022] The present application discloses a novel box-tube type foundation breakwater structure. Figure 1 As shown, a new box-type basic breakwater structure includes a front row of power towers 1 and a rear row of power towers 2 arranged in a front-to-back manner. The front row of power towers 1 can withstand the direct impact of waves to perform primary energy dissipation. A vortex deceleration zone is formed between the front row of power towers 1 and the rear row of power towers 2 to perform secondary energy dissipation. The rear row of power towers 2 disperses the residual wave impact force to perform tertiary energy dissipation.

[0023] A front row platform plate 11 is installed on the lower surface of the front row power generation tower 1, and a reinforcement slope 12 is installed at the front end of the front row platform plate 11. The reinforcement slope 12 connects the riverbed and the front row platform plate 11. A number of front row boxes 13 are installed on the lower surface of the front row platform plate 11. The front row boxes 13 are inserted into the riverbed as a whole, thereby forming a front row breakwater.

[0024] A rear platform plate 21 is installed on the lower surface of the rear power generation tower 2, and a plurality of rear boxes 22 and a load-bearing rockfill dam 23 are installed on the lower surface of the rear platform plate 21. The rear boxes 22 are installed close to the rear side wall of the front platform plate 11, and the lower ends of the rear boxes 22 are inserted into the riverbed. The load-bearing rockfill dam 23 is installed close to the rear side wall of the rear boxes 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 boxes 22, thereby forming a rear breakwater.

[0025] Compared with the existing technology, this application uses the cooperation of the front row of breakwaters and the rear row of breakwaters to enable waves to be dissipated multiple times, thereby improving the safety protection effect; and the front row of breakwaters and the rear row of breakwaters are both inserted into the riverbed through box tubes, thereby improving the stability of the breakwaters.

[0026] A horizontal front flow guide 14 is installed in the middle of the front power tower 1. Both ends of the front flow guide 14 are open and run through the front power tower 1. The impeller in the front power tower 1 is located inside the front flow guide 14. When the front wave surges in, the wave will flow into the front flow guide 14 and drive the impeller in the front power tower 1 to rotate, which in turn drives the generator in the front power tower 1 to generate electricity.

[0027] Since the overall height of the rear power tower 2 is greater than that of the front power tower 1, the waves discharged from the rear end of the front guide pipe 14 will directly hit the rear box 22, part of the waves will be reflected back to form reflected waves, and part of the reflected waves will flow back into the front guide pipe 14 and drive the impeller in the front power tower 1 to rotate, thereby allowing the generator to generate electricity again.

[0028] It is worth noting that, since the waves come in waves, it is only necessary to control the distance between the front row of power towers 1 and the rear row of power towers 2 so that the reflected waves can flow back in the front guide pipe 14 during the intervals between the two waves. This can avoid the impact and energy dissipation of the waves in the front guide pipe 14 as much as possible, thereby making full use of the wave energy.

[0029] In addition, when waves surge and cause a water level difference between the front and rear of the front power generation towers 1 , water will flow through the front flow guide pipe 14 due to its own gravity, thereby prompting the front power generation towers 1 to generate electricity.

[0030] like Figure 2 As shown, a horizontal front elastic unit 3 is provided on the front side of the front row power generation tower 1 , and the impeller in the front row power generation tower 1 is connected to the horizontal front elastic unit 3 through a horizontal front transmission unit.

[0031] 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 with an upper and lower interval. The same buffer plate 32 is embedded in the two buffer shells 31 for sliding along the front and rear directions. The buffer plate 32 is connected to the buffer shell 31 through a buffer spring 34 extending along the front and rear. A buffer pad 33 is installed at the front end of the buffer plate 32.

[0032] The horizontal front transmission unit includes at least one mounting base 35 installed at the rear end of the buffer plate 32, and an elastic telescopic rod 36 extending in the front-to-back direction is installed at the rear end of the mounting base 35. A rack 37 extending in the front-to-back direction is installed at the rear end of the elastic telescopic rod 36, and a first gear 38 is fixedly sleeved on the impeller main shaft of the front row power tower 1.

[0033] When the waves do not impact the horizontal front elastic unit 3 , the buffer spring 34 is in a natural state. At this time, the rack 37 is not engaged with the first gear 38 , so that the horizontal front elastic unit 3 does not affect the rotation of the impeller driven by the waves in the front flow guide duct 14 .

[0034] When the wave hits the buffer pad 33, the buffer plate 32 will move backward and push the rack 37 to move through the mounting seat 35 and the elastic telescopic rod 36. The rack 37 will engage with the first gear 38 and drive the impeller to rotate through the first gear 38. The impeller will drive the generator to generate electricity.

[0035] In addition, when the buffer pad 33 is impacted by waves, the buffer spring 34 will be gradually compressed and produce an energy dissipation effect, so that the buffer plate 32 will not have a rigid collision with the front row power generation tower 1.

[0036] It is worth noting that both the buffer pad 33 and the buffer plate 32 are provided with a through hole 321 , which corresponds to the open end of the front guide pipe 14 , so that the buffer pad 33 and the buffer plate 32 will not affect the waves from flowing into the front guide pipe 14 .

[0037] In this embodiment, there are two groups of horizontal front elastic units 3, which are respectively arranged 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 hit the horizontal front elastic units 3 on the rear side, causing the impeller to rotate to drive the generator to generate electricity.

[0038] It is worth noting that the racks 37 in the two groups of horizontal front elastic units 3 are arranged in an up-and-down staggered manner, so that the racks 37 in the two groups of horizontal front elastic units 3 will not have a rigid collision.

[0039] A vertical front elastic unit 4 is provided at least at one of the front and rear ends of the front power generation tower 1 , and the impeller in the front power generation tower 1 is connected to the vertical front elastic unit 4 via a vertical front transmission unit 5 .

[0040] The vertical front elastic unit 4 includes a horizontally arranged buoyancy plate 41. The side of the front row of power generation towers 1 is provided with a slide 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 of power generation towers 1, and the other end of the buoyancy plate 41 extends to the inside of the front row of power generation towers 1.

[0041] A plurality of vertically arranged limit columns 43 are installed in the slide 42, and the limit columns 43 are slidably passed through the buoyancy plate 41, so that the buoyancy plate 41 can only perform lifting and lowering movements; the upper and lower sides of the buoyancy plate 41 are connected to the groove wall of the slide 42 through connecting springs 44, so that the buoyancy plate 41 is in the middle of the slide 42 when not under force.

[0042] The upper and lower sides of the buoyancy plate 41 are connected to the groove wall of the slide groove 42 through folding blades 45. The folding blades 45 can block the waves and prevent the waves from flowing into the front row of power generation towers 1.

[0043] The vertical front transmission unit 5 includes a rotating rod 51 that can be flipped on the 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 power tower 1. The other end of the rotating rod 51 is rotatably connected to a push rod 52. A limiting cylinder 53 is slidingly sleeved on the push rod 52. The limiting cylinder 53 is fixedly installed inside the front power tower 1 so that the push rod 52 can only move along its own axis, and the sliding direction of the push rod 52 is parallel to the flipping plane of the rotating rod 51; a driving plate 54 is installed on the push rod 52, and a plurality of meshing teeth 55 are installed on the driving plate 54; a second gear 56 is fixedly sleeved on the impeller main shaft of the front power tower 1.

[0044] When the buoyancy plate 41 is not subjected to force, the meshing teeth 55 will not mesh with the second gear 56 , and the meshing teeth 55 will be distributed on both sides of the second gear 56 , so that the vertical front elastic unit 4 will not affect the rotation of the impeller.

[0045] When waves surge to the front power tower 1, the buoyancy of the water, the upward impact force of the waves on the buoyancy plate 41, and the downward impact force 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 engage with the second gear 56. The second gear 56 will drive the impeller in the front power tower 1 to rotate, so that the generator of the front power tower 1 generates electricity.

[0046] In this embodiment, vertical front elastic units 4 are provided at both the front and rear ends of the front row power generation tower 1, and the driving plates 54 in the two groups of vertical front elastic units 4 are staggered up and down, so that the driving plates 54 in the two groups of vertical front elastic units 4 will not have a rigid collision.

[0047] like Figure 3As shown, a horizontally arranged rear guide pipe 25 is installed in the middle of the rear power tower 2. Both ends of the rear guide pipe 25 are open and extend through the rear power tower 2. The impeller in the rear power tower 2 is located within the rear guide pipe 25. When the front wave surges in, because the overall height of the rear power tower 2 is greater than that of the front power tower 1, and the rear guide pipe 25 is located above the front guide pipe 14 and the horizontal front elastic unit 3, the waves at the middle water level can directly surge into the rear guide pipe 25 and drive the impeller in the rear power tower 2 to rotate, which in turn drives the generator in the rear power tower 2 to generate electricity.

[0048] A horizontal rear elastic unit 6 is provided on the rear power generation tower 2. The impeller in the rear power generation tower 2 is connected to the horizontal rear elastic unit 6 through a horizontal rear transmission unit. The horizontal rear elastic unit 6 is located at a height higher than the front guide pipe 14 and the front elastic unit.

[0049] The connection structure between the horizontal rear elastic unit 6 and the horizontal rear transmission unit is the same as the connection structure between the horizontal front elastic unit 3 and the horizontal front transmission unit, and the connection structure between the horizontal rear transmission unit and the rear row of power towers 2 is the same as the connection structure between the horizontal front transmission unit and the front row of power towers 1. Therefore, when the wave hits the horizontal rear elastic unit 6, the horizontal rear elastic unit 6 will drive the impeller of the rear row of power towers 2 to rotate through the horizontal rear transmission unit, and the impeller will drive the generator to generate electricity.

[0050] In this embodiment, there are two groups of horizontal rear elastic units 6, which are respectively arranged 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.

[0051] A vertical rear elastic unit 7 is provided at least at the front and rear ends of the rear power tower 2. The impeller in the rear power 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 tower 2 is the same as the connection structure between the vertical front transmission unit 5 and the front power 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.

[0052] When the waves surge to the rear power tower 2, the buoyancy of the water, the upward impact force of the waves and the downward impact force of the waves will cause the vertical rear elastic unit 7 to deform. The vertical rear elastic unit 7 will drive the impeller in the rear power tower 2 to rotate through the vertical rear transmission unit 8, and the impeller will drive the generator to generate electricity.

[0053] In this embodiment, vertical rear elastic units 7 are provided at both the front and rear ends of the rear power generation tower 2, and the driving plates 54 in the two groups of vertical rear elastic units 7 are staggered up and down, so that the driving plates 54 in the two groups of vertical rear elastic units 7 will not have a rigid collision.

[0054] A common water pipe 26, located below the rear flow pipe 25, is installed at the lower end of the rear power tower 2 and the upper surface of the rear platform 21. The rear power tower 2 contains two impellers, one located within the rear flow pipe 25 and the other within the water pipe 26. Both ends of the water pipe 26 are open and located at the front and rear sides of the rear power tower 2. Waves surging from both the front and rear sides flow into the water pipe 26, causing the impellers in the rear power tower 2 to rotate, driving the generator to generate electricity.

[0055] It is worth noting that when waves surge, causing a water level difference between the front and rear of the rear power towers 2, water will flow through the water guide pipe 26 and the rear guide pipe 25 due to its own gravity, thereby prompting the rear power towers 2 to generate electricity.

[0056] 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 flow guide pipe 14 and is coaxial with the front flow guide pipe 14 .

[0057] When the front waves flow into the front guide pipe 14, part of the waves discharged from the rear end of the front guide pipe 14 will flow into the water pipe 26 through the front branch pipe 27, causing the impeller in the rear power tower 2 to rotate, thereby prompting the rear power tower 2 to generate electricity.

[0058] When the rear waves flow into the water pipe 26 , part of the waves in the water pipe 26 can flow into the front flow pipe 14 through the front branch pipe 27 , causing the impellers in the front power towers 1 to rotate, thereby prompting the front power towers 1 to generate electricity.

[0059] The rear end side wall of the water pipe 26 is connected to a rear branch pipe 28. Waves at a low water level at the rear can flow into the water pipe 26 through the rear branch pipe 28, causing the impellers in the rear power towers 2 to rotate, thereby prompting the rear power towers 2 to generate electricity.

[0060] The implementation principle of a novel box-type foundation breakwater structure in an embodiment of the present application is as follows: during the surge of waves, the waves will directly hit or backflow to hit the horizontal front elastic unit 3 and the horizontal rear elastic unit 6, and will vertically hit the vertical front elastic unit 4 and the vertical rear elastic unit 7, and will also directly or indirectly flow into the front guide pipe 14, the rear guide pipe 25 and the water pipe 26, so that the front row of power towers 1 and the rear row of power towers 2 can generate electricity in various forms, thereby improving the recovery and utilization rate of wave energy, and further improving the power generation efficiency of wave energy.

[0061] The embodiment of the present application also discloses a novel working method of a box-tube type foundation breakwater structure. A novel working method of a box-tube type foundation breakwater structure includes the following working conditions: like Figure 4 As shown, when the front row of waves surges at low water level, that is, the front row of waves is not higher than the top of the front row of power generation towers 1, the breakwater structure will execute method A, which is as follows: The waves will hit the horizontal front elastic unit 3 on the front side and flow into the front guide pipe 14. When hitting the front power tower 1, the waves will flip and hit the vertical front elastic unit 4 on the front side. After hitting the rear box 22 and generating reflected waves, the waves will hit the horizontal front elastic unit 3 and the vertical front elastic unit 4 on the rear side. Part of the waves flowing into the front guide pipe 14 will flow into the water guide pipe 26 through the front branch pipe 27. The waves flowing between the front power tower 1 and the rear power tower 2 will flow back through the front guide pipe 14.

[0062] The horizontal front elastic unit 3, the front guide pipe 14, the vertical front elastic unit 4 and the water guide pipe 26 cooperate with each other, so that method A causes the front row of power generation towers 1 and the rear row of power generation towers 2 to generate electricity through various means such as wave impact, wave flow, reflected wave collision and wave backflow.

[0063] like Figure 5 As shown, when the front row of waves surges at a medium water level, that is, the front row of waves can directly impact the side of the rear row of power generation towers 2, the breakwater structure will implement method A and method B. Method B is as follows: The waves will hit the horizontal rear elastic unit 6 on the front side and the vertical front elastic units 4 on the front and rear sides and flow into the water guide pipe 26 and the rear guide pipe 25. When the waves hit the rear power generation tower 2, they will flip and hit the vertical rear elastic unit 7 on the front side. Part of the waves that flow into the rear of the rear power generation tower 2 will flow back through the water guide pipe 26 and the rear guide pipe 25, and part of the waves that flow into the rear of the rear power generation tower 2 will also hit the horizontal rear elastic unit 6 and the vertical rear elastic unit 7 on the rear side.

[0064] 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 cooperate with each other, so that method B prompts the front row of power generation towers 1 and the rear row of power generation towers 2 to generate electricity through various means such as wave impact, wave flow, reflected wave collision and wave backflow.

[0065] like Figure 6 As shown, when the front row of high water level waves surge, that is, the front row of waves can overturn the rear row of power generation towers 2, the breakwater structure will execute method A, method B and method C. Method C is as follows: The waves will roll over the rear row of power generation towers 2 and directly hit the vertical rear elastic units 7 and the rear horizontal rear elastic units 6 .

[0066] The vertical rear elastic unit 7 and the horizontal rear elastic unit 6 cooperate with each other, so that method C prompts the rear row power generation towers 2 to generate electricity through wave impact.

[0067] like Figure 7 As shown, when the rear row of low-water waves surges, that is, the rear row of waves is not higher than the aqueduct 26, the breakwater structure will execute method D, which is specifically as follows: The waves will flow into the water guide pipe 26 and be discharged between the front row of power towers 1 and the rear row of power towers 2 through the water guide pipe 26 and the front branch pipe 27. The waves between the front row of power towers 1 and the rear row of power towers 2 will hit the vertical front elastic unit 4 on the rear side and the horizontal front elastic unit 3 on the rear side and flow into the front guide pipe 14.

[0068] The water guide pipe 26, the vertical front elastic unit 4, the horizontal front elastic unit 3 and the front flow guide pipe 14 cooperate with each other, so that method D causes the front row power generation towers 1 and the rear row power generation towers 2 to generate electricity through various modes such as wave impact and wave flow.

[0069] like Figure 8 As shown, when the rear row surges with mid-water level waves, that is, the rear row waves are not higher than the top of the rear row power generation tower 2, the breakwater structure will execute method D and method E. Method E is specifically as follows: The waves will surge into the rear guide pipe 25 and hit the horizontal rear elastic unit 6 on the rear side. The waves in the rear guide pipe 25 will be discharged between the front power tower 1 and the rear power tower 2 and hit the vertical front elastic unit 4 on the rear side and the horizontal front elastic unit 3 on the rear side. When hitting the rear power tower 2, the waves will flip and hit the vertical rear elastic unit 7 on the rear side. Part of the waves that surge into the front power tower 1 will hit the horizontal front elastic unit 3 and the vertical front elastic unit 4 on the front side and flow back through the front guide pipe 14.

[0070] 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 cooperate with each other, so that method D causes the front row of power generation towers 1 and the rear row of power generation towers 2 to generate electricity through various means such as wave hitting, wave flow and wave collision.

[0071] like Figure 9 As shown, when the rear row surges with high water level waves, that is, the rear row waves can overturn the rear row power generation towers 2, the breakwater structure will execute method D, method E and method F. The specific method F is as follows: Part of the waves will roll over the rear power generation tower 2 and directly hit it, and the waves surging between the front power generation tower 1 and the rear power generation tower 2 will flow to the front of the front power generation tower 1 through the front guide pipe 14.

[0072] 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 cooperate with each other, so that method F causes the front row power towers 1 and the rear row power towers 2 to generate electricity through various means such as wave impact and wave flow.

[0073] The embodiment of the present application also discloses a method for installing a novel box-tube type foundation breakwater structure.

Water level adjustment: Adjust the water level at the front, middle and back sides of the breakwater to form a state where the back side is the highest, the middle side is the second, and the front side is the lowest, so that the front row power tower 1 and the back row power tower 2 can generate electricity through the water level difference (see Figure 15 ); S6, rear row installation: cast and install the rear row power generation tower 2 on the upper surface of the rear row platform plate 21 to form a rear row breakwater (see Figure 16 ).
