Description

Technical Field

[0001] The invention relates to the technical field of water surface photovoltaic power stations, and in particular to a water surface photovoltaic power station floating island constructed based on concrete technology. Background Art

[0002] A water-surface photovoltaic power station is a power generation facility that deploys a photovoltaic power generation system on the surface of a water body and converts solar energy into electrical energy through photovoltaic modules. A floating island of a water-surface photovoltaic power station is a floating platform deployed on the surface of a water body to support the overall structure of a photovoltaic power generation system.

[0003] In the prior art, water surface photovoltaic power stations are mainly small-scale water surface photovoltaic power stations, which usually use HDPE (High-Density Polyethylene) materials to modularly prefabricate photovoltaic power station floating island modules, assemble the floating islands at the construction site, and then use a fastening system to fasten the assembled floating islands to the designated location of the site.

[0004] However, the existing floating islands of water surface photovoltaic power stations have the following disadvantages:

[0005] 1. The cost of large-scale construction of floating islands is very high, including the cost of HDPE base materials, the cost of HDPE parts manufacturing, the cost of overall assembly and construction of floating islands, the cost of securing the floating islands on the water surface, and the subsequent operation and maintenance costs.

[0006] 2. The size of HDPE monomer parts manufactured by existing technology is too small, and large-scale floating islands must also be constructed by splicing small monomer parts, which leads to low construction efficiency;

[0007] 3. The floating island built with existing technology is easily damaged and the overall strength cannot be guaranteed. Since HDPE itself is not strong enough and cannot bear excessive loads in engineering, it must be strictly controlled during use, otherwise it is easy to be damaged;

[0008] 4. The existing technology usually adopts a matrix arrangement of floating islands, which is only suitable for the construction of floating islands with straight boundaries. In fact, the boundaries of the sites used for photovoltaic floating islands are often very tortuous. The existing technology can only abandon the outer boundaries and try to find straight boundaries inside. The ability to adapt to terrain is poor, and the utilization rate of the site area is not high;

[0009] Therefore, it is necessary to propose a floating island of water surface photovoltaic power station built based on concrete technology to flexibly float and lay it at the boundary of tortuous waters, so as to improve the terrain adaptability and stability of the photovoltaic floating island. Summary of the invention

[0030] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1-Figure 3 The present invention proposes a floating island of a water surface photovoltaic power station built based on concrete technology, including a photovoltaic floating island 1, which is floated and laid on the surface of the water area. The photovoltaic floating island 1 includes at least one floating module 2, and the floating module 2 is used to install photovoltaic components to obtain solar energy. The photovoltaic floating island 1 can set a floating module 2 for floating laying or set multiple floating modules 2 for combined floating laying according to the width of the water area to fill the water area with the maximum area to obtain solar energy to the maximum extent; wherein the floating module 2 is made of concrete material.

[0032] In this embodiment, a photovoltaic floating island 1 is floated and laid on the surface of a water area 3. During the floating laying process at the boundary of a tortuous water area 3, if the photovoltaic floating island 1 is laid in a narrow water area, a floating module 2 can be set according to the narrow width of the water area for floating laying. If the photovoltaic floating island 1 is laid in a wider water area, a plurality of floating modules 2 can be set according to the wider width of the water area for combined floating laying. In the water area 3, there can be photovoltaic floating islands 1 formed by a plurality of floating modules 2 and photovoltaic floating islands 1 formed by a plurality of floating modules 2, that is, the photovoltaic floating island 1 can be freely combined according to the restrictions of the boundary of the water area 3. For example, the water area flows from north to south, the water area near the north is narrower, and the water area near the south is wider. The overhead viewing angle is roughly trapezoidal. If the width of the narrower part of the water area can only accommodate one floating module 2 Photovoltaic floating island 1. At this time, a photovoltaic floating island 1 formed by a floating module 2 can be arranged in the waters near the north. This is the first photovoltaic floating island 1. If the width of the waters on the south side of the first photovoltaic floating island 1 can still only accommodate a photovoltaic floating island 1 formed by a floating module 2, then continue to arrange a photovoltaic floating island 1 formed by a floating module 2 in the waters near the south. This is the second photovoltaic floating island 1. If the width of the waters on the south side of the second photovoltaic floating island 1 can accommodate two floating modules 2 arranged from east to west, then a photovoltaic floating island 1 formed by two floating modules 2 arranged from east to west is arranged in the waters on the south side of the second photovoltaic floating island 1. The subsequent photovoltaic floating island 1 arrangements are similar, so that the photovoltaic floating island 1 can be floated and laid in accordance with the boundary of the tortuous waters to fill the maximum area of ​​the waters.

[0033] In summary, the floating island of the water surface photovoltaic power station built based on concrete technology can be flexibly floated and laid at the boundary of tortuous waters, effectively improving the terrain adaptability of the photovoltaic floating island.

[0034] Secondly, the floating body module 2 is made of concrete material. The concrete raw materials (such as cement and sandstone) are low-cost and widely available. At the same time, the concrete material technology is mature, and the construction technology and process are relatively mature, so the construction cost is also low. Compared with high polymer materials such as HDPE, the manufacturing cost is significantly reduced, thereby reducing the production cost of photovoltaic floating islands. And the use of concrete can manufacture large structural parts, thereby improving construction efficiency. At the same time, concrete structural parts have high compressive strength and good bearing capacity, can withstand greater loads, meet the load-bearing requirements of photovoltaic modules and other equipment, and reduce the risk of damage. Compared with the low strength and easy deformation of HDPE, the concrete floating body module 2 has more advantages in structural strength. Moreover, the concrete structural parts themselves have high strength, so after forming the floating island, a reliable fastening system can be set to ensure that the floating island is safer to the reservoir dam. In addition, the concrete material has a long service life, and has excellent wind and wave resistance, UV resistance, and corrosion resistance, and is particularly suitable for environments exposed to water and sunlight for a long time. Under high or low temperature conditions, the performance of the concrete float changes little and the performance is more stable.

[0035] In this embodiment, a plurality of floating modules 2 are arranged in sequence and fixedly connected end to end. In order to strengthen the structural strength of the photovoltaic floating island 1 formed by the plurality of floating modules 2, the plurality of floating modules 2 are arranged in sequence and fixedly connected end to end to form a long strip structure, so as to facilitate horizontal floating and laying on the water area, or the plurality of floating modules 2 are arranged in sequence along an arc and fixedly connected end to end to form a long arc structure, so as to facilitate floating and laying along the curved water area. The number of floating modules 2 can be adjusted according to the width of the water area. For example, the water area flows from north to south, the water area near the north is narrower, and the water area near the south is narrower. The water area on the side is wider, and the bird's-eye view is roughly trapezoidal. If the width of the water area near the north can accommodate three floating modules 2, then the photovoltaic floating island 1 formed by the three floating modules 2 arranged from east to west can be floated and laid on the water area near the north. If the width of the water area near the south can accommodate six floating modules 2, then the photovoltaic floating island 1 formed by the six floating modules 2 arranged from east to west can be floated and laid on the water area near the south. Due to the large difference in width of the water area in the south and the north, there is no rigid connection between the two photovoltaic floating islands 1, that is, the adjacent photovoltaic floating islands 1 are not rigidly connected.

[0036] In this embodiment, the floating module 2 includes a structural connection module 21 and a basic photovoltaic structure module 22. The basic photovoltaic structure module 22 is used to collect solar energy for photovoltaic power generation. The basic photovoltaic structure module 22 and the structural connection module 21 are fixedly connected by bolts or an external connection structure. The structural connection module 21 is used to provide a stable connection structure for the basic photovoltaic structure module 22. The structural connection module 21 is anchored to the bottom of the water to limit the basic photovoltaic structure module 22 to float on a fixed water surface area to prevent the basic photovoltaic structure module 22 from drifting along the water flow. The structural connection module 21 is electrically connected to the basic photovoltaic structure module 22 through a cable, and the structural connection module 21 supplies the electricity generated by the solar energy collected by the basic photovoltaic structure module 22 to the external power system.

[0037] In this embodiment, the floating module 2 includes N structural connection modules 21 and 2N basic photovoltaic structure modules 22. The N structural connection modules 21 are arranged in sequence, and one structural connection module 21 is fixedly connected to two basic photovoltaic structure modules 22 respectively, and the basic photovoltaic structure module 22 of the rear floating module 2 is fixedly connected to the structural connection module 21 of the front floating module 2; in some waters with a larger area, the boundary of the water area is not too tortuous. At this time, the floating module 2 can allocate the structural connection modules 21 and the basic photovoltaic structure modules 22 in a one-to-two manner. For example, one structural connection module 21 is paired with two basic photovoltaic structure modules 22 to form a floating module 2. This is a first type of floating module 2, which can be Two basic photovoltaic structure modules 22 are arranged from north to south, and then a structural connection module 21 is set between the two basic photovoltaic structure modules 22, that is, the floating body module 2 is arranged from north to south, and at this time, the width of the first type of floating body module 2 from east to west is the width of a basic photovoltaic structure module 22. If the water area flows from north to south, the water area near the north is narrower, and the water area near the south is wider, and the bird's-eye view is roughly trapezoidal. If the width of the water area near the north can accommodate the length of the four arranged floating body modules 2, a photovoltaic floating island 1 formed by four first type floating body modules 2 arranged from east to west and connected end to end can be set in the water area near the north. At this time, the water area near the north can be directly filled; For another example, two structural connection modules 21 are paired with four basic photovoltaic structure modules 22 to form a floating body module 2. Then, the above-mentioned one structural connection module 21 can be paired with two basic photovoltaic structure modules 22 to form a first group. Similarly, the two basic photovoltaic structure modules 22 are arranged from north to south, and then one structural connection module 21 is set between the two basic photovoltaic structure modules 22. Then, the same one structural connection module 21 is paired with two basic photovoltaic structure modules 22 to form a second group. Similarly, the two basic photovoltaic structure modules 22 are arranged from north to south, and then one structural connection module 21 is set between the two basic photovoltaic structure modules 22. Then, the first group and the second group are arranged end to end from east to west to form a second group. The second type of floating module 2, and at this time the width of the second type of floating module 2 from east to west is the width of two basic photovoltaic structure modules 22 plus a structural connection module 21. If the water area flows from north to south, the water area near the north is narrower, and the water area near the south is wider, and the bird's-eye view is roughly trapezoidal. If the width of the water area near the north can accommodate the length of two arranged second type floating modules 2, then a photovoltaic floating island 1 formed by two second type floating modules 2 arranged from east to west and connected end to end can be set in the water area near the north. At this time, the water area near the north can be directly filled. By analogy, the width of any water area can be filled, and then the length can be filled, so that the maximum area of ​​the water area can be filled.

[0038] In this embodiment, the floating module 2 includes N structural connection modules 21 and N+1 basic photovoltaic structure modules 22. The N+1 basic photovoltaic structure modules 22 are arranged in sequence, and the N structural connection modules 21 are arranged between the N+1 basic photovoltaic structure modules 22 in a staggered manner. One structural connection module 21 is fixedly connected to two basic photovoltaic structure modules 22 respectively. When the boundary of the water area is too tortuous, that is, the water area is bent in one direction, so that a relatively narrow water area is formed between the water area in the north and the water area in the south, and the water area in the north has been arranged with a photovoltaic floating island 1 of a suitable area, and the water area in the south has also been arranged with a photovoltaic floating island 1 of a suitable area, and this relatively narrow water area is suitable for arranging the basic photovoltaic structure modules 22 arranged in a single row, then it is necessary to adopt a connection method in which N structural connection modules 21 are arranged between the N+1 basic photovoltaic structure modules 22 in a staggered manner. The floating module 2, for example, the photovoltaic floating island 1 is arranged in the northern part and the southern part of the water area with a relatively narrow width, and the width of the water area from east to west is about 12 meters, the width of a basic photovoltaic structure module 22 from east to west is 3 meters, and the connection width of a structure connection module 21 is 0.5 meters, then the length of the floating module 2 formed by 3 basic photovoltaic structure modules 22 and 2 structure connection modules 21 arranged from east to west is 10 meters, and the length of the floating module 2 formed by 4 basic photovoltaic structure modules 22 and 3 structure connection modules 21 arranged from east to west is 13.5 meters, then the water area with a width of 12 meters can just arrange the floating module 2 formed by 3 basic photovoltaic structure modules 22 and 2 structure connection modules 21 arranged from east to west. At this time, the floating module 2 formed by 3 basic photovoltaic structure modules 22 and 2 structure connection modules 21 arranged from east to west should be arranged in the water area with a width of 12 meters.

[0039] In this embodiment, the floating body module 2 includes N structural connection modules 21 and N+2 basic photovoltaic structure modules 22. The N structural connection modules 21 are fixedly connected to the N+2 basic photovoltaic structure modules 22 respectively, and one structural connection module 21 is located between two basic photovoltaic structure modules 22. When the boundary of the water area is too tortuous and has a tendency to converge, that is, the northern water area is curved from east to west, and then converges from north to south, so that the northern water area is relatively spacious and the southern water area is relatively narrow, and it is a triangular structure from a bird's-eye view. At this time, it is suitable to use N structural connection modules 2. 1 is respectively fixedly connected to N+2 basic photovoltaic structure modules 22, and a structural connection module 21 is located between two basic photovoltaic structure modules 22 to set the floating body module 2. For example, the water area bends from east to west and then converges from north to south to form an inverted right triangle water area with a length of about 18 meters from east to west, a height of about 11 meters from north to south, and a hypotenuse of about 21.1 meters. If the width of a basic photovoltaic structure module 22 from east to west is 3 meters, and the connection width of a structural connection module 21 is 0.5 meters, it is necessary to connect 5 basic photovoltaic structure modules 22 with 4 structural connection modules 21 are arranged from east to west to fill the long side of the inverted right triangle water area. The arrangement length of 5 basic photovoltaic structure modules 22 and 4 structure connection modules 21 from east to west is 17 meters, which can just fill the water area with a length of 18 meters from east to west. Then, 2 basic photovoltaic structure modules 22 are arranged from north to south to connect with a basic photovoltaic structure module 22 at the end, and 2 structure connection modules 21 are respectively connected to the basic photovoltaic structure modules 22 arranged from north to south, and 2 basic photovoltaic structure modules 22 are connected from north to south to a basic photovoltaic structure module 22 at the end plus two structure connection modules. The total length of the connected modules 21 is 10 meters, which can just fill the water area with a height of about 11 meters from north to south. Then, two basic photovoltaic structure modules 22 are arranged from east to west from the west of the first basic photovoltaic structure module 22 connected from north to south, and then one structural connection module 21 is connected to the remaining unconnected basic photovoltaic structure modules 22. At this time, the 9 basic photovoltaic structure modules 22 and the 7 structural connection modules 21 are spliced ​​to form a shape close to an inverted right triangle, and are suitable for a length of about 18 meters from east to west, a height of about 11 meters from north to south, and a hypotenuse of about 21.1 meter inverted right triangle water area, that is, this type of arrangement forms a structure connection module 21 that can be located between two basic photovoltaic structure modules 22 and connect the basic photovoltaic structure modules 22 on both sides respectively. If there are enough structure connection modules 21 and basic photovoltaic structure modules 22, the floating module 2 formed by this connection method can change its shape arbitrarily, for example, the floating module 2 can be connected to form various triangles, rectangles, trapezoids, parallelograms, rhombuses, hexagons, etc., to adapt to filling water areas of different shapes. .

[0040] In this embodiment, the floating module 2 includes N structural connection modules 21 and N+3 basic photovoltaic structure modules 22. The N structural connection modules 21 are fixedly connected to the N+3 basic photovoltaic structure modules 22 respectively. One structural connection module 21 is located between three basic photovoltaic structure modules 22, and the three basic photovoltaic structure modules 22 are evenly distributed circumferentially around one structural connection module 21. When the water area is relatively narrow, for example, the water area flows from north to south, the water area near the north is relatively narrow, and the water area near the south is also relatively narrow, but the width of the water area near the south is greater than that of the water area near the north. If the width of the water area in the south from west to east is about 8 meters, and the width of the water area in the north from west to east is about 6 meters, then the water area in the north and the water area in the south form a trapezoidal water area with a short side of 6 meters and a long side of 8 meters. If a basic photovoltaic structure module 2 2 The width from east to west is 3 meters, and the connection width of a structural connection module 21 is 0.5 meters. Then, one structural connection module 21 is located between three basic photovoltaic structure modules 22, and the floating module 2 formed by the three basic photovoltaic structure modules 22 being evenly distributed circumferentially around one structural connection module 21 is a floating module 2 that is close to an equilateral triangle shape. The width from east to west of two basic photovoltaic structure modules 22 and one structural connection module 21 is 6.5 meters, that is, the side length of the equilateral triangle is approximately 6.5 meters, and the floating module 2 can just be arranged in the trapezoidal water area with a short side of 6 meters and a long side of 8 meters, and the floating module 2 that is close to an equilateral triangle shape can be rotated at any angle with the middle structural connection module 21 as the rotation center, so as to be placed at the corner of the water area, or in the boundary of a narrow and tortuous water area, so as to be fully filled.

[0041] In this embodiment, the basic photovoltaic structure module 22 includes a load-bearing floating platform 221, and the floating island 1 of the water surface photovoltaic power station includes a plurality of photovoltaic panels 222. The optimal shape of the load-bearing floating platform 221 is a regular hexagonal structure. The load-bearing floating platform 221 can also be a circular structure, an elliptical structure or other polygonal structures. The load-bearing floating platform 221 is a hollow structure formed by pouring concrete. Before pouring, it is necessary to use a mold to reserve a preset space inside the load-bearing floating platform 221 so that air can be filled inside after pouring. An adjustment port is provided on one side of the load-bearing floating platform 221, and the adjustment port can be opened to fill water to adjust the internal space. The air proportion in the structure is adjusted to achieve appropriate buoyancy so that it floats on the water surface line 4. One side of the load-bearing floating platform 221 is fixedly connected to one side of the structural connection module 21. A plurality of photovoltaic panels 222 are arrayed on the upper surface of the load-bearing floating platform 221. The plurality of photovoltaic panels 222 are all fixedly connected to the upper surface of the load-bearing floating platform 221. They can be fixedly connected by bolts or by card slots. The plurality of photovoltaic panels 222 are electrically connected to the structural connection module 21 through cables, so that the electricity generated by the plurality of photovoltaic panels 222 can flow into the external power system through the structural connection module 21.

[0042] In this embodiment, the structural connection module 21 includes a connection platform 211, and the floating island 1 of the water surface photovoltaic power station includes an anchoring system 212 and a power supply cable system. When the ratio of the structural connection module 21 in the floating body module 2 to the basic photovoltaic structure module 22 is 1 to 3, that is, when one structural connection module 21 needs to be connected to three basic photovoltaic structure modules 22, the optimal shape of the connection platform 211 is a Y-shaped structure, and at this time the basic photovoltaic structure module 22 needs to be a regular hexagonal structure, that is, three regular hexagonal basic photovoltaic structure modules 22 are circumferentially distributed around the connection platform 211 of the Y-shaped structure. If they are connected continuously, a honeycomb-like connection structure will be formed. The connection platform 211 can be cast by concrete. The hollow structure formed by building can also be a hollow steel structure. The connecting platform 211 can be used as a standing area for workers when repairing the basic photovoltaic structure module 22. If the overall area of ​​the basic photovoltaic structure module 22 is large enough, the connecting platform 211 can also be a large-area platform, which can be used as a berthing port area for repair ships. One side of the connecting platform 211 is fixedly connected to one side of the basic photovoltaic structure module 22, one end of the anchoring system 212 is fixedly connected to the connecting platform 211, and the other end of the anchoring system 212 is anchored to the bottom of the water. The anchoring system 212 includes a plurality of rope anchors, and the plurality of rope anchors are evenly dispersed around the connecting platform 211 as the center, and the anchoring end of the rope anchor extends to the bottom area vertically below the outer side of the basic photovoltaic structure module 22 domain, one end of the power supply cable system is fixedly connected to the connection platform 211 and is electrically connected to the basic photovoltaic structure module 22 through the cable, and the other end of the power supply cable system is electrically connected to the external power system. The power supply cable system is composed of multiple branch cables, multiple branch cables, and a bus cable. If the ratio of the structural connection module 21 in the floating module 2 to the basic photovoltaic structure module 22 is 1 to 3, the multiple branch cables will be divided into three groups, and there will be three branch cables. One end of the multiple branch cables of the first group corresponds to and is electrically connected to the multiple photovoltaic panels 222 in the first basic photovoltaic structure module 22, respectively, and the other end of the multiple branch cables of the first group is connected to one end of the first branch cable, and one end of the multiple branch cables of the second group One end of each of the plurality of branch cables of the second group corresponds to and is electrically connected to the plurality of photovoltaic panels 222 in the second basic photovoltaic structure module 22, the other end of each of the plurality of branch cables of the second group is connected to one end of the second branch cable, one end of each of the plurality of branch cables of the third group corresponds to and is electrically connected to the plurality of photovoltaic panels 222 in the third basic photovoltaic structure module 22, the other end of each of the plurality of branch cables of the third group is connected to one end of the third branch cable, and then the other ends of the three branch cables are electrically connected to one end of a bus cable at the same time, and the other end of the bus cable is electrically connected to an external power system. When the plurality of photovoltaic panels 222 generate photovoltaic power, the current can flow from the plurality of branch cables to the plurality of branch cables, and finally converge to the bus cable for transmission.

[0043] In this embodiment, the basic photovoltaic structure module 22 is any one of a polygonal structure, a circular structure, and an elliptical structure. The best shape among the polygonal structures is a regular hexagonal structure. When the basic photovoltaic structure module 22 is a regular hexagonal structure, whether it is a floating body module 2 formed by N structural connection modules 21 and 2N basic photovoltaic structure modules 22, or a floating body module 2 formed by N structural connection modules 21 and N+1 basic photovoltaic structure modules 22, or a floating body module 2 formed by N structural connection modules 21 and N+2 basic photovoltaic structure modules 22, or a floating body module 2 formed by N structural connection modules 21 and N+3 basic photovoltaic structure modules 22, the structure formed by splicing the structural connection modules 21 and the basic photovoltaic structure modules 22 can be relatively compact, which is convenient for adaptive splicing to adapt to waters of different shapes. The basic photovoltaic structure modules 22 with circular structures and elliptical structures are more suitable for waters with similar arc-shaped curves.
