Description

Technical Field

[0001] The invention relates to the technical field of breakwaters, in particular to a composite floating breakwater with high and low pontoons having cavities. Background Art

[0002] In recent years, solar photovoltaic power generation has developed rapidly as a green, clean and renewable energy source. Photovoltaic power generation is based on the principle of the photovoltaic effect and uses solar cells to directly convert sunlight energy into electrical energy.

[0003] Land-based photovoltaic power generation occupies a large area of land and is typically located in desert areas, far from power consumption centers. This increases transmission costs and requires the construction of transmission equipment along the route, which has hindered the development of photovoltaic power generation. To address the land shortage in power consumption centers and the land use conflict between the development of photovoltaic power plants, floating photovoltaic power generation has developed rapidly in recent years. Floating photovoltaic power generation does not occupy land resources, has higher power generation efficiency, and can be built in waters close to power consumption centers.

[0004] Due to the harsh marine environment, offshore photovoltaic structures face the test of strong winds and high waves. Existing fixed breakwaters are usually made of reinforced concrete or steel structures. Such breakwaters are expensive to build, can damage the marine ecology and environment, and have poor wave-breaking effects. Summary of the Invention

[0005] In view of this, the present invention provides a composite floating breakwater with high and low pontoons and an offshore photovoltaic field with cavities to solve the problems of high breakwater construction cost and poor wave-breaking effect in the prior art.

[0006] The present invention provides a composite floating breakwater with high and low pontoons with cavities, comprising a first pontoon, a connecting assembly and a second pontoon. The side of the connecting assembly is connected to the first pontoon, and the upper part of the connecting assembly is provided with a accommodating cavity that passes through from top to bottom. The second pontoon is connected to a side of the connecting assembly away from the first pontoon. The top height of the second pontoon is greater than the height of the first pontoon and the top height of the connecting assembly. The second pontoon is located on a side close to the photovoltaic assembly.

[0007] Beneficial effect: In the present invention, the top height of the second pontoon is set to be greater than the top height of the first pontoon and the connecting assembly. When facing large waves or extreme sea conditions, the waves moving toward the photovoltaic assembly can pass over the first pontoon and flow into the accommodating cavity of the connecting assembly, achieving a certain degree of wave elimination. At the same time, the second pontoon can further intercept large-scale overtopping waves, with good wave blocking and wave elimination effects, and enhance the resistance of the offshore floating photovoltaic assembly structure to wave impact.

[0008] In an optional embodiment, the connection assembly includes connection plates, and two connection plates are vertically connected between the first pontoon and the second pontoon, and a receiving cavity is formed between the two connection plates.

[0009] Beneficial effects: In the present invention, the two connecting plates vertically arranged between the first pontoon and the second pontoon can form a accommodating cavity for accommodating waves passing over the first pontoon. The structure is simple, which can reduce the overall weight of the breakwater and wave-breaking dam, making it easier for the breakwater to float on the sea, thereby ensuring the breakwater and wave-breaking effect.

[0010] In an optional embodiment, a receiving cavity is provided on the side of the first buoyancy tank and / or the connecting assembly.

[0011] Beneficial effects: The present invention configures the first buoyancy box and / or the connecting assembly as a hollow structure with a accommodating cavity on the side, which can reduce the overall weight of the breakwater and facilitate the breakwater to float on the sea, thereby ensuring the breakwater and wave-breaking effect.

[0012] In an optional embodiment, the composite floating breakwater with high and low pontoons having cavities further includes a wave-breaking component, which is vertically arranged on a side of the second pontoon away from the connecting component, and the upper and lower ends of the wave-breaking component extend out of the top and bottom planes of the second pontoon.

[0013] Beneficial effects: The lower part of the wave-breaking component in the present invention can block the water flow below the second pontoon, thereby reducing the flow rate of the ocean current. The upper part of the wave-breaking component further prevents ultra-high waves from passing over the top of the second pontoon, so that the overall wave-breaking dam can achieve the effect of wave elimination.

[0014] In an optional embodiment, the wave-proof component includes a fixing part and a wave-proof part. Several fixing parts are arranged on the side of the second pontoon away from the connecting component. The fixing parts are provided with mounting holes. The wave-proof parts are installed in the mounting holes. The upper and lower ends of the wave-proof parts extend out of the top and bottom planes of the second pontoon.

[0015] In an optional embodiment, the composite floating breakwater with high and low pontoons having cavities further includes an anchoring assembly, one end of which is arranged at the bottom of the first pontoon or the second pontoon, and the other end is suitable for being arranged on the seabed.

[0016] Beneficial effects: The present invention arranges an anchoring assembly at the bottom of the first pontoon or the second pontoon, which allows the wave-breaking dam to float on the periphery of the photovoltaic assembly and enables the entire structure to remain stable under extreme sea conditions, thereby avoiding possible damage to the structure caused by severe weather and improving the overall durability and risk resistance.

[0017] In an optional embodiment, the first pontoon, the connecting assembly and the second pontoon have the same width.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0035] The following combination Figures 1 to 4 , describing embodiments of the present invention.

[0036] According to an embodiment of the present invention, Figure 1 and Figure 2 As shown, a composite floating breakwater 100 with high and low pontoons with cavities is provided, comprising a first pontoon 1, a connecting assembly 2 and a second pontoon 3. The side of the connecting assembly 2 is connected to the first pontoon 1, and the connecting assembly 2 is provided with a accommodating cavity 201 that passes through from top to bottom. The second pontoon 3 is connected to the side of the connecting assembly 2 away from the first pontoon 1. The top height of the second pontoon 3 is greater than the top height of the first pontoon 1 and the connecting assembly 2. The second pontoon 3 is located on the side close to the photovoltaic assembly 200.

[0037] Specifically, in this embodiment, the first pontoon 1, the connection assembly 2 and the second pontoon 3 are floated on the sea, and the first pontoon 1, the connection assembly 2 and the second pontoon 3 are connected in sequence, and the side of the second pontoon 3 away from the first pontoon 1 faces the photovoltaic assembly 200.

[0038] In this embodiment, the first pontoon 1, the connecting component 2 and the second pontoon 3 are all cubic structures. The first pontoon 1 and the connecting component 2 have the same height. The connecting component 2 is provided with a accommodating cavity 201 that runs through from top to bottom. The bottom of the first pontoon 1 is flush with the bottom of the connecting component 2 and the bottom of the second pontoon 3, and the top height of the second pontoon 3 is greater than the top height of the connecting component 2.

[0039] Figure 2 The direction of the arrow in the middle is the direction of wave movement.

[0040] In the present invention, the top height of the second pontoon 3 is set to be greater than the top height of the first pontoon 1 and the connecting component 2. When facing large waves or extreme sea conditions, the waves moving toward the photovoltaic component 200 can pass over the first pontoon 1 and flow into the accommodating cavity 201 of the connecting component 2, achieving a certain degree of wave elimination. At the same time, the second pontoon 3 can further intercept large-scale overtopping waves, has good wave blocking and wave elimination effects, and enhances the resistance of the offshore floating photovoltaic component 200 structure to wave impact.

[0041] In one embodiment, Figure 1As shown, the connection assembly 2 includes a connection plate 202 . The two connection plates 202 are vertically connected between the first pontoon 1 and the second pontoon 3 , and a receiving cavity 201 is formed between the two connection plates 202 .

[0042] Specifically, in this embodiment, the connecting plate 202 has a rectangular structure, the height of the connecting plate 202 is the same as that of the first pontoon 1, the two connecting plates 202 are symmetrically arranged, the outer side of the connecting plate 202 is flush with the outer sides of the first pontoon 1 and the second pontoon 3, and the inner sides of the two connecting plates 202 form a accommodating cavity 201. When the waves move from a distance toward the first pontoon 1, the side of the first pontoon 1 away from the connecting component 2 blocks the waves. Part of the waves flows over the first pontoon 1 and into the accommodating cavity 201, and the rest is blocked by the second pontoon 3.

[0043] In the present invention, two connecting plates 202 vertically arranged between the first pontoon 1 and the second pontoon 3 can form a accommodating cavity 201 for accommodating waves passing over the first pontoon 1. The structure is simple, which can reduce the overall weight of the composite floating breakwater 100 with high and low pontoons and cavities, making it easier for the composite floating breakwater 100 with high and low pontoons and cavities to float on the sea, thereby ensuring the wave-breaking and wave-dissipating effect.

[0044] In one embodiment, Figure 2 As shown, a receiving cavity 201 is provided on the side of the first buoyancy tank 1 and / or the connecting assembly 2 .

[0045] Specifically, in this embodiment, the first pontoon 1 and the second pontoon 3 both adopt a three-dimensional structure with a side portion that is a through-containment cavity 201 .

[0046] The present invention configures the first pontoon 1 and / or the connecting assembly 2 as a hollow structure with a accommodating cavity 201 on the side, which can reduce the overall weight of the composite floating breakwater 100 with high and low pontoons having cavities, making it easier for the composite floating breakwater 100 with high and low pontoons having cavities to float on the sea, thereby ensuring the wave-breaking and wave-dissipating effect.

[0047] In one embodiment, Figure 1 and Figure 2 As shown, the composite floating breakwater 100 with high and low pontoons having cavities also includes a wave-breaking component 4, which is vertically arranged on the side of the second pontoon 3 away from the connecting component 2, and the upper and lower ends of the wave-breaking component 4 extend out of the top and bottom planes of the second pontoon 3.

[0048] Specifically, in this embodiment, a wave-proof component 4 is vertically provided on the side of the second pontoon 3 away from the connecting component 2. The width of the wave-proof component 4 is the same as the width of the second pontoon 3, and the height is greater than the second pontoon 3. The upper and lower ends of the wave-proof component 4 extend out of the top and bottom of the second pontoon 3.

[0049] In the present invention, the lower part of the wave-breaking component 4 can block the water flow below the second pontoon 3, thereby reducing the flow rate of the ocean current. The upper part of the wave-breaking component 4 further prevents ultra-high waves from passing over the top of the second pontoon 3, so that the overall composite floating wave-breaking dam 100 with cavity high and low pontoons can achieve the effect of wave elimination.

[0050] In one embodiment, Figure 2 As shown, the wave-proof component 4 includes a fixing part 401 and a wave-proof part 402. Several fixing parts 401 are arranged on the side of the second pontoon 3 away from the connecting component 2. The fixing parts 401 are provided with mounting holes, and the wave-proof parts 402 are installed in the mounting holes. The upper and lower ends of the wave-proof parts 402 extend out of the top and bottom planes of the second pontoon 3.

[0051] Specifically, in this embodiment, there is no specific limitation on the shape of the fixing member 401. For example, in this embodiment, the fixing member 401 is a cylindrical structure, and several fixing members 401 are fixed in parallel on the middle of the side wall of the second pontoon 3 away from the connecting component 2; the wave-proof member 402 is cylindrical, and its outer diameter matches the inner diameter of the fixing member 401. The wave-proof member 402 is inserted into the fixing member 401, and the height of the wave-proof member 402 is greater than the height of the second pontoon 3. The upper and lower ends of the wave-proof group extend out of the top and bottom of the second pontoon 3.

[0052] In one embodiment, the composite floating breakwater 100 with high and low pontoons having cavities further includes an anchoring assembly, one end of which is arranged at the bottom of the first pontoon 1 or the second pontoon 3, and the other end is suitable for being arranged on the seabed.

[0053] Specifically, the mooring assembly in this embodiment includes an anchor chain and an anchor. The anchor is fixed to the seabed. One end of the anchor chain is hinged to the anchor, and the other end is hinged to the bottom of the first pontoon 1 or the second pontoon 3 .

[0054] The present invention provides an anchoring assembly at the bottom of the first pontoon 1 or the second pontoon 3, so that the composite floating breakwater 100 with high and low pontoons with cavities can float on the periphery of the photovoltaic assembly 200, and the entire structure can remain stable under extreme sea conditions, avoiding possible damage to the structure caused by bad weather, and improving the overall durability and risk resistance.

[0055] In one embodiment, Figure 1 As shown, the first pontoon 1, the connecting assembly 2 and the second pontoon 3 have the same width.

[0056] Specifically, in this embodiment, the first pontoon 1, the connecting assembly 2 and the second pontoon 3 have the same width, so that the side of the composite floating breakwater 100 with high and low pontoons with cavities can be a flat surface.

[0057] In one embodiment, the first pontoon 1 , the connection assembly 2 and the second pontoon 3 are made of reinforced concrete.

[0058] Specifically, in this embodiment, the first pontoon 1, the connecting assembly 2 and the second pontoon 3 are made of reinforced concrete, which can enable the composite floating breakwater 100 with cavity high and low pontoons to resist damage from natural factors such as seawater erosion, weathering and ultraviolet radiation, and enable the composite floating breakwater 100 with cavity high and low pontoons to have high compressive strength and good overall stability. The composite floating breakwater 100 with cavity high and low pontoons can maintain structural integrity when subjected to wave impact and is not prone to deformation or damage. At the same time, the composite floating breakwater 100 with cavity high and low pontoons made of reinforced concrete has a certain weight, which helps to increase the stability of the composite floating breakwater 100 with cavity high and low pontoons and reduce drift and vibration caused by wind and waves. In addition, concrete, as an inorganic material, does not contain harmful substances, so that the composite floating breakwater 100 with cavity high and low pontoons generates less waste during construction and use, which is beneficial to protecting the marine ecological environment.

[0059] The present invention adopts a reinforced concrete structure, which has the advantages of high strength and good stability, and has a lower manufacturing cost than a pure steel structure.

[0060] In one embodiment, the wave-proof member 402 is made of bamboo.

[0061] Specifically, in this embodiment, because the bamboo material has a certain degree of flexibility and elasticity, the wave-breaking member 402 can produce better deformation and recovery capabilities under the action of water flow. In the composite floating breakwater 100 with high and low pontoons with cavities, this characteristic helps to guide the water flow to form a backflow, thereby more effectively dissipating and weakening the energy of the ocean current. At the same time, because it has high strength and its porous structure also helps the ocean current to pass through, reducing the impact of the water flow on the composite floating breakwater 100 with high and low pontoons with cavities, it not only achieves a light and strong structure, but also significantly improves the environmental friendliness of the product. In addition, its unique fiber structure and natural texture, while optimizing the fluid flow path, enhance the diversion efficiency and stability, so that the entire device exhibits the dual advantages of excellent performance and sustainability in the fluid treatment process.

[0062] The wave-proof member 402 of the present invention is made of bamboo material, which has excellent mechanical properties, and the raw material is light and high-strength, and the raw material source is wide, and the use cost is low.

[0063] like Figure 3 and Figure 4As shown, the composite floating breakwater 100 with high and low pontoons with cavities can be applied to offshore photovoltaic fields. The offshore photovoltaic fields include photovoltaic modules 200 and the above-mentioned composite floating breakwater 100 with high and low pontoons with cavities. The photovoltaic modules 200 are suitable for floating on the sea. Several composite floating breakwaters 100 with high and low pontoons with cavities are adjacently connected and enclosed on the sea surface to form a horizontal circumferentially closed accommodation chamber, and the photovoltaic modules 200 are arranged in the accommodation chamber.

[0064] Specifically, the photovoltaic module 200 is floated on the sea, and a plurality of composite floating breakwaters 100 with high and low pontoons with cavities are connected in parallel and enclosed to form a horizontal circumferentially closed accommodation chamber, forming a physical protective barrier, which can effectively reduce the direct impact and kinetic energy of waves on the photovoltaic module 200, significantly reduce the impact of wave force, and make the waters near the photovoltaic module 200 stable.

[0065] In this embodiment, the shape of the accommodating chamber is not specifically limited. For example, in this embodiment, the accommodating chamber can be circular, square, triangular, etc.

[0066] Preferably, a plurality of composite floating breakwaters 100 with high and low pontoons having cavities are connected in parallel to form a Figure 3 As shown in rectangular or Figure 4 The circular receiving chamber is shown, and the photovoltaic component 200 is arranged in the receiving chamber.

[0067] In this embodiment, the second pontoon 3 has dimensions of 12 to 30 meters wide, 20 to 50 meters long, and a height of 1.2 to 1.5 times the wave height. The first pontoon 1 has dimensions of 12 to 30 meters wide, 20 to 50 meters long, and a height of 0.7 to 1.0 times the wave height. The width of the accommodating cavity 201 of the connecting assembly 2 is approximately 0.1 times the wavelength. The height of the wave-breaking element is approximately 6 meters. Each breakwater can be formed into a circular or rectangular composite floating breakwater 100 with a cavity height or width of 100 to 1500 meters, as needed.

[0068] The present invention encloses several composite floating breakwaters 100 with hollow high and low pontoons outside the photovoltaic module 200. Under the impact of waves, the composite floating breakwaters 100 with hollow high and low pontoons can block and eliminate waves, effectively reducing the direct impact force and kinetic energy transmitted by the waves, thereby significantly reducing the fluctuations in the waters near the photovoltaic module 200 and ensuring the safe and stable operation of the photovoltaic module 200. In adverse climates and sea conditions, such as strong winds, large waves, or tidal changes, the first pontoon 1 can achieve wave elimination, the second pontoon 3 can further block waves, and the lower part of the wave-breaking assembly 4 can block the water flow, thereby reducing the overall current velocity.

[0069] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
