[0042] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0044] Example 1: This example provides a triangular floating photovoltaic array suitable for use near the coast. Figures 1 to 7 As shown, it mainly includes: a mooring device 10, a cable connecting member 20 connected to the mooring device 10, a frame connecting member 30 with a similar structure to the cable connecting member 20, and a photovoltaic support module 40.

[0045] The mooring device 10 includes a mooring anchor cable 13, one end of which is connected to an anchor block 11, and the other end is connected to a guide cable connector 20 at a corresponding position on the photovoltaic support module 40 through a corresponding guide cable, and a spring damper 12 is provided in the middle of the mooring anchor cable 13;

[0046] The frame connector 30 is composed of two fork rods 31 and a cross shaft 32 located in the middle. The ends of the two fork rods 31 are respectively fixedly connected to two adjacent photovoltaic support modules 40, and the structure of the cable connector 20 is the same as that of a single fork rod 31.

[0047] The photovoltaic support module 40 includes a triangular frame 41 , a plurality of spherical floats 42 are provided below the triangular frame 41 , and a plurality of photovoltaic panels 43 with adjustable inclination angles are provided above the triangular frame 41 .

[0048] Further, the fairlead cable includes a double fairlead cable 14 and a single fairlead cable 15, the double fairlead cable 14 is Y-shaped as a whole, and the single fairlead cable 15 is straight as a whole.

[0049] Further, the fairlead connector 20 is installed at the middle and both ends of the outer edge of the outermost photovoltaic support module 40 in the photovoltaic array, and the fairlead connector 20 located at the middle of the outer edge of the photovoltaic support module 40 is connected with the corresponding mooring cable 13 through the single fairlead cable 15; the fairlead connector 20 located at the end of the outer edge of the photovoltaic support module 40 is connected with the fairlead connector 20 located at the end of the outer edge of the adjacent photovoltaic support module 40 through the double fairlead cable 14 and the corresponding mooring cable 13.

[0050] Further, the mooring cable 13 is composed of an upper cable and a lower cable, one end of the lower cable is connected with the fairlead connection point on the anchor block 11, and the other end is connected with the lower end of the spring damper 12, one end of the upper cable is connected with the corresponding double fairlead cable 14 or single fairlead cable 15, and the other end is connected with the upper end of the spring damper 12.

[0051] Further, the triangular frame 41 is equilateral triangle as a whole, and is divided into four local equilateral triangles by support rods, and the spherical float 42 is installed below the vertex of each local equilateral triangle.

[0052] Further, a plurality of adjustable inclination photovoltaic panels 43 are installed on the triangular frame 41 at equal intervals, the length of each adjustable inclination photovoltaic panel 43 is the same as the width of the corresponding frame, and the orientations of the plurality of adjustable inclination photovoltaic panels 43 on each triangular frame 41 are consistent.

[0053] Further, the adjustable inclination photovoltaic panel 43 includes a solar photovoltaic panel 433, two telescopic rods 432 are respectively connected to the top ends of the solar photovoltaic panel 433, and the bottom ends of the two telescopic rods 432 and the bottom ends of the solar photovoltaic panel 433 are fixedly installed on the triangular frame 41 through the corresponding spherical hinge support 431.

[0054] Further, three frame connectors 30 are connected between every two adjacent photovoltaic support modules 40, and the three frame connectors 30 are respectively connected to the two end points and the middle point of one side of the corresponding triangular frame 41.

[0055] Further, the straight line connected at the centers of the two holes of the fork head structure of the fairlead connector 20 is parallel to the plane where the corresponding photovoltaic support module 40 is located.

[0056] Example 2: This embodiment provides a triangular floating photovoltaic array suitable for use near the coast, such as Figure 2 As shown, the mooring device 10 includes an anchor block 11 located on the seabed, a mooring cable 13, a double-fairlead cable 14 connecting the mooring cable 13 and the cable guide connector 20, and a single-fairlead cable 15; the mooring device also includes a spring damper 12, and the mooring method adopts tension mooring. The working principle of the spring damper 12 is similar to that of a spring. When the water level changes with the tide or season, the spring is stretched or compressed due to the change in the height of the floating photovoltaic array, which can change the length of the mooring cable 13, maintain the tension of the mooring, and prevent the mooring cable 13 from being over-tensioned or over-slack. The mooring cable 13 is divided into two sections. The section of mooring cable 13 near the bottom of the water is connected to the rigging point on the anchor block 11 at one end and to the bottom of the spring damper at the other end. The section of mooring cable 13 near the spring damper 12 is connected to the bottom of the double-hole rigging cable 14 or the single-hole rigging cable 15 at one end and to the top of the spring damper 12 at the other end. The double-hole rigging cable 14 or the single-hole rigging cable 15 has one end near the rigging connector 20 connected to the top of the second section of mooring cable and the other end connected to the rigging connector 20.

[0057] like Figure 4 As shown, the universal joint structure of the frame connector 30 is composed of two fork rods 31 with one end that cannot rotate and a cross shaft 32 in the middle. The fork rods can rotate around the cross shaft within a certain extent. The universal joint structure of the present invention is different from the general universal joint. The other end of the fork rod is fixed to the photovoltaic support module 40 and cannot rotate, which increases the stability of the array in wind and waves, while reducing the manufacturing process and the probability of wear. The guide cable connector 20 has the same fork rod structure as the universal joint structure of the frame connector 30, which reduces manufacturing costs, facilitates large-scale manufacturing of the photovoltaic support module 40, and is more flexible in splicing when the number of modules is large. The straight line connecting the centers of the two holes in the fork structure is parallel to the plane where the photovoltaic support module 40 is located, so that the two holes are evenly stressed, which increases the durability of the guide cable connector 20 and facilitates the connection of the mooring anchor cable 13.

[0058] like Figure 5As shown, the photovoltaic support module 40 includes a triangular frame 41 for support, a spherical float 42 connected to the bottom of the triangular frame, and an adjustable tilt photovoltaic panel 43 above the triangular frame. The triangular frame 41 is shaped like a large equilateral triangle divided into four equal small equilateral triangles, and its cross-section is a hollow rectangle. The photovoltaic support module 40 includes six spherical floats 42, which are connected to the vertices of the small equilateral triangles of the triangular frame 41 by a square steel bar. The spherical shape has better fluid properties and can improve the movement performance of the array in waves. The adjustable photovoltaic panel 43 includes four ball hinge supports 431, two telescopic rods 432 connecting the ball hinge supports 431, and a photovoltaic panel 433. The four ball joint supports 431 are respectively located at the two symmetrical corners of the photovoltaic panel 433 and the corresponding positions of the triangular frame 41. The two telescopic rods 432 respectively connect the left and right photovoltaic panels 433 and the ball joint supports 431 on the triangular frame 41. The telescopic rods 432 adjust the inclination angle of the photovoltaic panel 433 by rotating at the ball joint support 431 and extending and retracting along the axial direction.

[0059] Further, such as Figure 3 As shown, the double-fairguide cable 14 is in a Y-shape, and the single-fairguide cable 15 is in a straight line.

[0060] Furthermore, the double-fairguide anchor cable 14 is connected to two fairlead connectors 20 corresponding to two photovoltaic support modules 40, reducing the number of mooring devices 10 and saving costs; the single-fairguide anchor cable 15 is connected to one fairlead connector 20 corresponding to one photovoltaic support module 40, improving mooring stability.

[0061] Furthermore, the mooring anchor cable 13 passes through two holes of the fork structure of the cable guide connector 20 .

[0062] Furthermore, each photovoltaic support module 40 connected to the mooring device has three cable guide connectors 20, which are located at the two end points and the midpoint of one side of the triangular frame.

[0063] Furthermore, every two photovoltaic support modules are connected by three frame connectors 30, which are located at two end points and a midpoint of one side of the triangular frame, thereby improving the stability of the entire photovoltaic array.

[0064] Furthermore, each photovoltaic support module 40 includes three adjustable photovoltaic panels 43 of unequal lengths, and the length of the adjustable photovoltaic panel 43 is the same as the length of the triangular frame 41 at the corresponding position.

[0065] Furthermore, the adjustable photovoltaic panels 43 of the triangular modules 40 in different directions are oriented in the same direction to convert solar energy with maximum efficiency, which can be achieved by installing the adjustable photovoltaic panels 43 in two different ways.

[0066] Embodiment three, based on the same inventive concept, the present example also provides a triangular floating photovoltaic array arrangement method as described above, comprising the following steps:

[0067] S1, from the total number of n photovoltaic support modules, 6 form an equilateral hexagonal array, n≥6;

[0068] S2, when 6

[0069] S3, when 12

[0070] S4, when 24

[0071] S5, when n>28, on the basis of the photovoltaic array arranged in step S3, the remaining (n-24) photovoltaic support modules are arranged in groups of four to form multiple equilateral triangular arrays, and the last group of photovoltaic support modules that does not meet four is connected into a separate array, then the separate array and each equilateral triangular array are regarded as a whole photovoltaic support module, and step S2 is re-executed.

[0072] Specifically, as shown in Figure 8 In order to ensure the hydrodynamic performance of the photovoltaic array, the symmetry in the horizontal and vertical directions needs to be maintained. Based on the hexagonal array composed of 6 photovoltaic support modules, when the total number of modules is not more than 12, the number of photovoltaic support modules in the upper and lower rows is uniformly increased based on the 6 photovoltaic support modules, and the number of photovoltaic support modules in each row cannot exceed 3; when the total number of modules is greater than 12 but not more than 20, the number of photovoltaic support modules in the left and right columns is uniformly increased based on the 6 photovoltaic support modules, and the number of photovoltaic support modules in each row cannot exceed 4; when the total number of modules is greater than 20 but not more than 24, the number of photovoltaic support modules in the left and right columns is uniformly increased, and when the number of modules is increased to 24, the overall shape is similar to that of 6 modules, showing equi-proportional enlargement.

[0073] The above method can be applied to any total number of modules: starting with a hexagonal array of 6N (N is the number of modules that can form an equilateral triangle, N = 1, 4, 12, etc.) photovoltaic support modules, the array can be constructed with N modules increasing in arithmetic progression. If the multiple relationship cannot be met, the smaller N is used to make up the difference. For example, if the total number of modules is 203, and N = 12, the maximum number of modules that can be arranged is 16n. For the remaining 13 modules, N = 4 to make up 8 modules. For the remaining 3 modules, N = 1 to make up 3 modules.

[0074] Furthermore, all parts of this application that are not described in detail are the same as the existing technology or are implemented using the existing technology.

[0075] In summary:

[0076] 1. The present invention is applicable to different coastal high and low tide environments. By maintaining the tension through the spring damper of the mooring device, the impact of changes in the waterline height on the entire floating photovoltaic system can be reduced.

[0077] 2. The structure of the present invention is stable and reliable. Each photovoltaic support module is connected by multiple frame connectors, and the frame of each support module adopts a stable triangular structure, making the overall structure stable;

[0078] 3. The present invention has good wind and wave resistance. By adopting a spherical float form, the hydrodynamic performance is good. By adopting a reasonable array arrangement, the overall photovoltaic array is close to central symmetry, and the movement in wind and waves is more stable.

[0079] 4. The present invention has high power generation efficiency, compact arrangement between modules, high space utilization, and adjustable photovoltaic panel inclination angle to cope with different seasonal illumination angles; the arrangement of triangular modules is flexible and suitable for different marine environments;

[0080] 5. Through the reasonable arrangement of mooring devices, connectors and photovoltaic support modules, the present invention has a compact overall structure, is stable and reliable, and the cable guide connectors and frame connectors adopt partially identical structures, which can effectively reduce processing and manufacturing costs; and the connection between modules only needs to be fixed through a cross axis, which is convenient for installation, maintenance and promotion.

[0081] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
