Description

Technical Field

[0001] The present invention relates to the technical field of clean energy development and utilization, and in particular to a structure with wave-breaking and power generation effects, a floating wind power and photovoltaic combined power generation system, and a construction method. Background Art

[0002] Currently, wind power installations and grid-connected photovoltaic capacity are experiencing explosive growth, and offshore wind power development is rapidly developing. With the increasing power of offshore wind turbines and the expansion of offshore wind farms into the deep sea, floating wind turbine technology has become a hot research topic.

[0003] Since renewable energy sources such as water, wind and light have complementary characteristics, realizing the comprehensive complementary development of water, wind and light is an important future development direction of renewable energy.

[0004] However, due to the poor wave environment and high wave height in the deep sea, there is currently no technology that can provide a stable wave environment for floating photovoltaic arrays and floating wind turbines in the deep sea, thereby realizing the comprehensive development of floating wind power and floating photovoltaics in the deep sea area. Summary of the Invention

[0005] The purpose of the present invention is to address the technical defects of the existing technology and provide a structure with wave-breaking and power generation effects, a floating wind power and photovoltaic combined power generation system, and a construction method.

[0006] To this end, the present invention provides a structure with wave-blocking and wave-breaking and power generation effects, which includes at least one structural body;

[0007] Inside one side of each structural body, a curved, hollow wave-blocking section is provided;

[0008] On one side of each structural body, a wave-breaking section is provided protruding outwards and distributed obliquely;

[0009] The wave-blocking section is located obliquely above the wave-breaking section;

[0010] The bottom surface of the wave-breaking section is directly connected to the bottom surface of the main structure and is located on the same horizontal plane;

[0011] The top surface height of the wave-breaking section gradually decreases as the distance from the wave-blocking section increases;

[0012] The highest position of the top surface of the wave-breaking section is directly connected to the lower edge of the wave-blocking section;

[0013] There are multiple concave square compartments evenly distributed on the top of the wave-breaking section;

[0014] Just above the lower end of the wave-blocking section, a cavity for installing power generation equipment is provided;

[0015] The power generation equipment is installed in the cavity, and at least one bidirectional impulse turbine is installed;

[0016] The power output of each bidirectional impulse turbine is connected to the drive input of a DC generator;

[0017] The top of the structural body is directly above each bidirectional impulse turbine and is provided with at least one air inlet and outlet;

[0018] The air inlet and outlet are directly connected to the power generation equipment installation cavity;

[0019] The bottom of the power generation equipment installation cavity is provided with a wave inlet at the bottom of the power generation equipment installation cavity, which is used to allow waves to flow into the power generation equipment installation cavity;

[0020] Each structural body is provided with a hollow sealed buoyancy-providing cavity;

[0021] The buoyancy providing cavity and the wave-blocking section are spaced apart from each other.

[0022] In addition, the present invention also provides a floating wind power and photovoltaic combined power generation system, including a floating photovoltaic array, multiple new floating wind turbine foundations, and multiple arc-shaped wave-breaking and power generation walls;

[0023] Any two adjacent new floating wind turbine foundations are connected to the two ends of the arc-shaped wave-breaking and power generation wall respectively;

[0024] The wave-breaking and power-generating wall comprises a plurality of structures connected in sequence, which have the wave-breaking and power-generating effects as described above;

[0025] Multiple new floating wind turbine foundations, together with multiple arc-shaped wave-breaking and power generation walls, form a circular photovoltaic protection structure;

[0026] A floating photovoltaic array is installed inside the circular photovoltaic protection structure.

[0027] In addition, the present invention also provides a construction method of the aforementioned floating wind power and photovoltaic combined power generation system, comprising the following steps:

[0028] The first step is to tow multiple new floating wind turbine foundations with wind AC generators installed on top to the designated installation location using a tugboat, with gaps reserved for the floating photovoltaic arrays to pass through.

[0029] The second step is to ballast the ballast tanks inside the pontoon of the new floating wind turbine foundation so that the draft of the new floating wind turbine foundation reaches the installation depth of the second mooring line. This will give the second mooring line initial tension, which is conducive to ensuring the stability of the new floating wind turbine foundation. The anchoring device is then installed at the designated location on the seabed. The second mooring line on the seabed is then hoisted by the winch on the tugboat and connected to each new floating wind turbine foundation.

[0030] The third step is to use the crane equipment on the tugboat to connect multiple structures with wave-breaking and power-generating functions to the new floating wind turbine foundation through flexible connectors;

[0031] The fourth step is to wet-tow the entire floating photovoltaic array to a location between multiple new floating wind turbine foundations using a tugboat. The winch on the tugboat then winches all the first mooring lines on the seabed and connects the first mooring lines to the floating photovoltaic array. The anchoring device is then fixedly connected to the second mooring line and the adjacent first mooring line on the floating photovoltaic array.

[0032] At the same time, any two adjacent new floating wind turbine foundations are connected to the two ends of an arc-shaped wave-breaking and power generation wall through flexible connectors, so that a complete wave-breaking and power generation arc wall structure is formed between any two adjacent new floating wind turbine foundations;

[0033] The wave-breaking and power-generating wall comprises a plurality of structural bodies connected in sequence, which have the effects of wave-breaking and power-generating.

[0034] Step 5: Continue to wet-tow at least one new floating wind turbine foundation with a wind turbine AC generator installed on top to the designated location using a tugboat, then use the winch on the tugboat to winch up the second mooring line on the seabed and connect the second mooring line to the new floating wind turbine foundation, and then fix the anchor device to the second mooring line and the adjacent first mooring line on the floating photovoltaic array;

[0035] In the sixth step, the new floating wind turbine foundation dragged in the fifth step is connected to the new floating wind turbine foundation dragged in the first step through an arc-shaped wave-breaking and power generation wall, and finally the floating wind power and photovoltaic combined power generation system is obtained.

[0036] It can be seen from the technical solution provided by the present invention above that, compared with the prior art, the present invention provides a structure with wave-breaking and wave-breaking and power generation effects, a floating wind power and photovoltaic combined power generation system, and a construction method. The design is scientific, and the structure with wave-breaking and wave-breaking and power generation effects designed by the present invention can effectively block waves and break waves, and use wave energy to generate electricity, thereby providing a stable wave environment for floating photovoltaic arrays and floating wind turbines in deep and distant sea areas, and then constructing a floating wind power and photovoltaic combined power generation system, which is conducive to the comprehensive development of floating wind power and floating photovoltaics in deep and distant sea areas, and has important practical significance.

[0037] By applying the present invention, based on the structure provided by the present invention that has wave-breaking and wave-breaking and power generation effects, floating wind power and floating photovoltaics are combined into a joint power generation system. The application of this structure to the floating foundation at the bottom of the new floating wind turbine provides a stable power generation environment for the floating photovoltaic array. Each of the structures contains two bidirectional impulse turbines and corresponding DC generators, and uses pneumatic wave energy to generate electricity, thereby improving the comprehensive power generation capacity and the power generation per unit area at sea, and ultimately realizing the comprehensive development of floating wind power and floating photovoltaics in deep-sea areas, and providing a solution for the combined development of deep-sea wind energy, solar energy, wave energy and other resources.

For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set. Those skilled in the art will understand the specific meanings of the above terms in this patent based on the specific circumstances.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0056] See also Figure 1a 、 Figure 1b 、 Figure 2 , the present invention provides a structure with wave-breaking and power-generating effects, comprising at least one structural body 1;

[0057] Inside one side of each structural body 1 (i.e. the side facing the incoming waves), a curved, hollow wave-blocking section 3 is provided;

[0058] On one side of each structural body 1 (i.e. the side facing the incoming waves, i.e. the same side with the wave-blocking section 3), a wave-breaking section 2 is provided protruding outwards and distributed obliquely;

[0059] The wave-blocking section 3 is located obliquely above the wave-dissipating section 2;

[0060] The bottom surface of the wave-breaking section 2 is directly connected to the bottom surface of the structural body 1 and is located on the same horizontal plane;

[0061] The top surface height of the wave-breaking section 2 gradually decreases as the distance from the wave-blocking section 3 increases;

[0062] The highest position of the top surface of the wave-breaking section 2 is directly connected to the lower edge of the wave-blocking section 3;

[0063] A plurality of concave square compartments 20 are evenly distributed on the top of the wave-breaking section 2;

[0064] Just above the lower end of the wave-blocking section 3, a power generation equipment installation cavity 30 is provided;

[0065] At least one (for example, two) bidirectional impulse turbines 6 are installed in the power generation equipment installation cavity 30;

[0066] The power output of each bidirectional impulse turbine 6 is connected to the drive input of a DC generator 5;

[0067] The top of the structural body 1 is provided with at least one air inlet and outlet 7 directly above each bidirectional impulse turbine 6;

[0068] The air inlet and outlet 7 are directly connected to the power generation equipment installation cavity 30;

[0069] The bottom of the power generation equipment installation cavity 30 is provided with a wave inlet (i.e., bottom opening) 31 for allowing waves to flow into the power generation equipment installation cavity 30;

[0070] Each structural body 1 is provided with a hollow sealed buoyancy providing cavity 4;

[0071] The buoyancy providing cavity 4 and the wave-blocking section 3 are spaced apart from each other;

[0072] It should be noted that, in the present invention, the structure having the wave-breaking and wave-breaking and power-generating effects is hollow inside, and the cavity 4 can provide a certain buoyancy through buoyancy.

[0073] It should be noted that, for the present invention, a power generation equipment installation cavity 30 is provided above the lower end of the arc-shaped wave-breaking section 3, in which two bidirectional impulse turbines 6 and corresponding DC generators 5 are arranged, and pneumatic wave energy is used to generate electricity. The opening at the top of the cavity (i.e., the air inlet and outlet 7) facilitates the intake and discharge of air.

[0074] It should be noted that the present invention can use aerodynamic wave energy to generate electricity. When a wave hits, it will first pass through the inclined wave-breaking section 2. At this time, some waves have been blocked by the square compartment 20. Next, some waves will enter the power generation equipment installation cavity 30 through the wave inlet at the bottom of the power generation equipment installation cavity (i.e., the bottom opening). Before this, due to the existence of the air inlet and outlet 7 at the top, there will be a certain amount of air in the power generation equipment installation cavity 30. The surge of the waves drives the air in the power generation equipment installation cavity 30 to be compressed, and then the compressed air will first pass through the two-way impulse turbine 6, and then the blades in the two-way impulse turbine 6 will be driven to rotate, and the DC generator 5 connected to the turbine 6 will be driven to work through mechanical transmission to generate electricity, thereby converting mechanical energy into electrical energy. Subsequently, the air is discharged through the air inlet and outlet 7, and then the wave will pass through the arc-shaped wave-blocking section 3. At this point, the wave will be completely blocked and return, and then the returning wave will pass through the inclined wave-breaking section 2 again to be fully eliminated, and this is carried out through the reciprocating movement of the wave.

[0075] It should be noted that, except for the air inlet and outlet 7 at the top, only the bottom of the power generation equipment installation cavity 30 is open, and the rest of the cavity is closed.

[0076] It should be noted that the bidirectional impulse turbine is a mature device with existing technology. For example, the impulse turbine generator set produced by Mingda Electric Motor Factory in Pingnan County, Guangxi can be used; the DC generator is also a mature device with existing technology. For example, the Hongju series DC generator produced by Chongqing Hongju Mechanical and Electrical Equipment Co., Ltd. can be used.

[0077] In the present invention, in a specific implementation, when the structure with wave-breaking and power-generating effects includes a plurality of structural bodies 1, any two adjacent structural bodies 1 are connected via a flexible connector.

[0078] It should be noted that the flexible connector can be a Dyneema cable with high strength, low temperature resistance and light density. Of course, it is not limited to a simple cable. Under the premise of ensuring the continuity of the arc-shaped wave-breaking and power generation wall formed by connecting multiple structural bodies 1 in sequence, the flexible connector has high flexibility and strength performance. Therefore, it can reduce the load effect of the movement of the wave-breaking and power generation wall under wave load on the flexible connector and the floating wind power structure by allowing a certain relative movement between adjacent wave-breaking and power generation structures.

[0079] It should be noted that the flexible connector is an existing connector, for example, a Dyneema cable can be used, specifically a cable produced by Jiangsu Shenyun Rope Co., Ltd.

[0080] In the present invention, in a specific implementation, the wave-blocking section 3 is an arc-shaped (specifically circular arc-shaped) opening groove.

[0081] In the present invention, in a specific implementation, the square compartment 20 is a concave groove structure.

[0082] A plurality of square cells 20 are distributed at equal intervals on the top of the wave-breaking section 2 .

[0083] It should be noted that the top of the wave-breaking section 2 is provided with comprehensive and dense square cabins 20 with wave-breaking function.

[0084] In the present invention, in a specific implementation, the structure with wave-breaking and power generation effects uses seawater-corrosion-resistant concrete material.

[0085] In the present invention, in a specific implementation, the shape of the structural body 1 is preferably an arc shape, or an elongated strip shape (for example, the overall outline shape is a rectangular parallelepiped shape).

[0086] In the present invention, in a specific implementation, the structure having wave-blocking and wave-breaking and power generation effects comprises a plurality of arc-shaped structural bodies 1;

[0087] A plurality of structural bodies 1 are sequentially connected together to form an arc-shaped wave-breaking and power-generating wall (i.e., a protective power-generating mechanism).

[0088] Based on the structure with wave-breaking and power generation effects provided by the present invention, see Figures 3 to 7 as well as Figures 8a to 8f The present invention also provides a floating wind power and photovoltaic combined power generation system, which includes a floating photovoltaic array 9, a plurality of (not limited to Figure 3 Four) novel floating wind turbine foundations 8, and multiple arc-shaped wave-breaking and power-generating walls;

[0089] Any two adjacent new floating wind turbine foundations 8 are respectively connected to the two ends of the arc-shaped wave-breaking and power generation wall;

[0090] The wave-breaking and power-generating wall comprises a plurality of structures connected in sequence, which have the wave-breaking and power-generating effects as described above;

[0091] A plurality of new floating wind turbine foundations 8 together with a plurality of arc-shaped wave-breaking and power generation walls form a circular photovoltaic protection structure;

[0092] Inside the circular photovoltaic protection structure, a floating photovoltaic array 9 is provided;

[0093] In the present invention, in a specific implementation, the novel floating wind turbine foundation 8 includes a hollow pontoon 80;

[0094] A wind turbine generator set 81 (including a common wind turbine generator set structure such as a wind turbine tower, blades and a generator set) is provided on the top of the buoyancy box 80;

[0095] A ballast inlet 82 is provided on the top of the buoyancy tank 80;

[0096] It should be noted that, except for the ballast inlet 82 , the outer side surfaces of the buoyancy tank 80 , such as the outer side walls and the bottom, are sealed.

[0097] Each side surface around the buoyancy box 80 is respectively provided with a plurality of structures with wave-breaking and power-generating effects.

[0098] In a specific implementation, the buoyancy tank 80 is in a polyhedron shape, such as a rectangular parallelepiped shape.

[0099] It should be noted that the pontoon 80 can be a hollow rectangular pontoon structure or a polyhedron structure. The pontoon is the floating structure at the bottom of the floating wind turbine. The interior of the pontoon 80 is divided into multiple compartments (i.e., ballast tanks, which have openings for facilitating the placement of ballast materials such as seawater) to adjust the balance posture of the floating wind turbine and improve the stability of the wind turbine. When the sea conditions are bad or encounter extreme sea conditions with strong winds and waves, the ballast tanks can be immediately ballasted with seawater to increase the draft of the floating wind turbine foundation 8 and improve the stability of the wind turbine when subjected to wind and wave loads.

[0100] In specific implementation, the side arrangement of the pontoon 80 has a structure with wave-breaking and power generation effects;

[0101] In terms of specific implementation, the mooring system at the bottom of the new floating wind turbine foundation 8 includes a catenary-type second mooring line 11 and an anchoring device, including an anchoring device shared by the new floating wind turbine foundation 8 and the floating photovoltaic array 9, which is efficient and cost-effective to construct.

[0102] In the present invention, in a specific implementation, the second mooring line 11 connected to the floating photovoltaic array 9 and the first mooring line 10 connected to the adjacent new floating wind turbine foundation 8 are connected to the same anchoring device 12 (which can be called a shared anchoring device).

[0103] It should be noted that, for the present invention, all anchoring devices (including shared anchoring devices) are suction anchors with mature existing technology. They can be transported to the designated seabed location, pumped out and sunk. Because the water pressure load provided under deep water conditions is large, the installation time is short and quick and convenient.

[0104] It should be noted that, in the present invention, the floating photovoltaic array 9 is surrounded by multiple floating wind turbines and multiple arc-shaped wave-breaking and power generation walls connected by a structure with wave-breaking and power generation effects. The second mooring line 11 connected to the floating photovoltaic array 9 and the first mooring line 10 connected to the adjacent new floating wind turbine foundation 8 share the same anchoring device 12, see Figure 3 、 Figure 4 shown.

[0105] It should be noted that in the present invention, the electricity generated by the DC generator 5 and the floating photovoltaic array 9 is direct current (DC). The floating photovoltaic array 9 converts solar energy into electrical energy through photovoltaic panels. The electricity generated by the DC generator 5 and the floating photovoltaic array 9 is combined and transmitted via cables to a nearby oil and gas platform or to a shore-based substation. The electricity is then converted to alternating current (AC) by an inverter within the platform or substation and supplied to electricity users. Furthermore, the electricity generated by the wind turbine AC generator 8 is low-voltage AC, which is then transmitted to the substation and converted to high-voltage AC before being supplied to electricity users.

[0106] In the present invention, in a specific implementation, the new floating wind turbine foundation 8 is connected to the wave-breaking and power-generating wall through a flexible connector.

[0107] In the present invention, in a specific implementation, any two adjacent structural bodies 1 in structures with wave-breaking and wave-breaking and power generation effects are connected by flexible connectors, so that multiple structural bodies 1 in structures with wave-breaking and wave-breaking and power generation effects connected together in sequence can form a wave-breaking and wave-breaking and power generation wall.

[0108] It should be noted that, for the present invention, by using flexible connectors for connection, it is possible to allow appropriate relative movement between adjacent wave-blocking and wave-breaking structures while ensuring the continuity of the arc-shaped wave-blocking and wave-breaking walls and power generation walls, thereby reducing the load effect of the overall movement of the wave-blocking and wave-breaking structures under wave loads on the flexible connectors and the floating wind power structure.

[0109] In order to obtain the floating wind power and photovoltaic combined power generation system provided by the present invention, the present invention also provides a construction method of the floating wind power and photovoltaic combined power generation system, see Figures 8a to 8f As shown, the following steps are included:

[0110] First step, see Figure 8a As shown, multiple (for example, three) new floating wind turbine foundations 8 with wind AC generator sets 81 installed on top are wet-towed to a designated installation location by a tugboat, and a gap is reserved for the floating photovoltaic array 9 to pass through;

[0111] In the first step, in specific implementation, for multiple new floating wind turbine foundations 8, the gap size (i.e., the spacing) between two new floating wind turbine foundations 8 is larger than the width of the floating photovoltaic array 9 to facilitate the floating photovoltaic array 9 to pass through.

[0112] In the first step, in terms of specific implementation, the draft depth of the new floating wind turbine foundation 8 during wet towing is determined by the foundation stability and the real-time sea conditions during towing. After reaching the designated installation location, the draft continues to reach the designated depth.

[0113] It should be noted that wet towing means directly moving the new floating wind turbine foundation 8 with a tugboat while the foundation is in a floating state.

[0114] Step 2, see Figure 8b As shown, the ballast tanks (the ballast tanks are not shown in the figure; the ballast tanks are hollow and sealed compartments, and the buoyancy tank 80 may include multiple ballast tanks) inside the pontoon 80 of the novel floating wind turbine foundation 8 are ballasted so that the draft of the novel floating wind turbine foundation 8 reaches the installation depth of the second mooring line 11. This allows the second mooring line 11 to have initial tension, which is beneficial for ensuring the stability of the novel floating wind turbine foundation 8 and installing the anchoring device 12 at a designated location on the seabed. Then, the second mooring line 11 on the seabed is hoisted by the winch on the tugboat, and the second mooring line 11 is connected to each novel floating wind turbine foundation 8.

[0115] In the second step, in specific implementation, the designated position on the seabed where the anchoring device 12 is installed is located between two adjacent new floating wind turbine foundations 8, and the center point thereof is located on a vertical plane;

[0116] The vertical plane is a vertical plane where a straight line perpendicular to a line connecting the center points of the two novel floating wind turbine foundations 8 lies.

[0117] Step 3, see Figure 8c As shown, a plurality of structures with wave-breaking and power-generating effects are connected to the new floating wind turbine foundation 8 through flexible connectors by means of a crane on a tugboat;

[0118] Step 4, see Figure 8d As shown, the floating photovoltaic array 9 is wet-towed as a whole to a position between multiple novel floating wind turbine foundations 8 by a tugboat, and then the winch on the tugboat winches all the first mooring lines 10 on the seabed and connects the first mooring lines 10 to the floating photovoltaic array 9, and the anchoring device 12 is fixedly connected to the second mooring line 11 and the adjacent first mooring line 10 on the floating photovoltaic array 9;

[0119] At the same time, any two adjacent new floating wind turbine foundations 8 are connected to the two ends of an arc-shaped wave-breaking and power generation wall through flexible connectors, so that a complete wave-breaking and power generation arc wall structure (i.e., an arc-shaped wave-breaking and power generation wall) is formed between any two adjacent new floating wind turbine foundations 8;

[0120] The wave-breaking and power-generating wall comprises a plurality of structural bodies 1 connected in sequence and having the effects of wave-breaking and power-generating.

[0121] Step 5, see Figure 8e As shown, the novel floating wind turbine foundation 8 with at least one wind AC generator set 81 mounted on top is wet-towed to a designated location by a tugboat, and then the second mooring line 11 on the seabed is hoisted by a winch on the tugboat, and the second mooring line 11 is connected to the novel floating wind turbine foundation 8, and then the anchoring device 12 is fixedly connected to the second mooring line 11 and the first mooring line 10 adjacent to the floating photovoltaic array 9;

[0122] In the fifth step, in terms of specific implementation, the center point of the new floating wind turbine foundation 8 dragged to the specified position in the fifth step and the center points of the multiple new floating wind turbine foundations 8 in the first step are located on the circumference of the same circle, and the circle has the center point of the floating photovoltaic array 9 as the center.

[0123] Step 6, see Figure 8f As shown, the new floating wind turbine foundation 8 towed in the fifth step is connected to the new floating wind turbine foundation 8 towed in the first step through an arc-shaped wave-breaking and power generation wall, and finally the floating wind power and photovoltaic combined power generation system is obtained.

[0124] In the sixth step, in specific implementation, when there are multiple new floating wind turbine foundations 8 towed in the fifth step, any two adjacent new floating wind turbine foundations 8 among the multiple new floating wind turbine foundations 8 are connected through an arc-shaped wave-breaking and power generation wall.

[0125] In the present invention, in a specific implementation, the field size of the floating wind power and photovoltaic combined power generation system can be a circle with a diameter of 2000m;

[0126] In the present invention, in a specific implementation, the wind AC generator set 81 on the top of the novel floating wind turbine foundation 8 can be a set with a power generation capacity of more than 16MW.

[0127] In the present invention, in a specific implementation, the floating photovoltaic array 9 includes a plurality of photovoltaic floats;

[0128] It should be noted that floating photovoltaic arrays and photovoltaic floats are mature and widely used photovoltaic products with existing technologies, and will not be described in detail here.

[0129] Specifically, the dimensions of a single photovoltaic float are 2m long x 1.2m wide x 0.4m high, and are made of HDPE (high-density polyethylene).
