[0022] 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 cable guide connector 20 at a corresponding position on the photovoltaic support module 40 through a corresponding cable guide cable, and a spring damper 12 is provided in the middle of the mooring anchor cable 13; 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; The photovoltaic support module 40 includes a triangular frame 41 , a plurality of spherical floats 42 are disposed below the triangular frame 41 , and a plurality of photovoltaic panels 43 with adjustable inclination angles are disposed above the triangular frame 41 .

[0023] Furthermore, the cable guide and anchor cable comprises a double-fairguide hole cable guide and anchor cable 14 and a single-fairguide hole cable guide and anchor cable 15. The double-fairguide hole cable guide and anchor cable 14 is Y-shaped as a whole, and the single-fairguide hole cable guide and anchor cable 15 is straight-lined as a whole.

[0024] Furthermore, the cable connector 20 is installed in the middle and both ends of the outer edge of the outermost photovoltaic support module 40 in the photovoltaic array, and the cable connector 20 located in the middle of the outer edge of the photovoltaic support module 40 is connected to the corresponding mooring anchor cable 13 through a single cable guide hole cable guide anchor cable 15; the cable connector 20 located at the end of the outer edge of the photovoltaic support module 40 is connected together with the cable connector 20 at the end of the outer edge of the adjacent photovoltaic support module 40 through a double cable guide hole cable guide anchor cable 14 with the corresponding mooring anchor cable 13.

[0025] Furthermore, the mooring anchor cable 13 is composed of an upper anchor cable and a lower anchor cable, one end of the lower anchor cable is connected to the cable guide connection point on the anchor block 11, and the other end is connected to the lower end of the spring damper 12, one end of the upper anchor cable is connected to the corresponding double-lead cable anchor cable 14 or single-lead cable anchor cable 15, and the other end is connected to the upper end of the spring damper 12.

[0026] Furthermore, the triangular frame 41 is an equilateral triangle as a whole, and the inside is equally divided into four partial equilateral triangles by support rods, and the spherical float 42 is installed under the vertex of each partial equilateral triangle.

[0027] Furthermore, a plurality of adjustable-tilt photovoltaic panels 43 are installed at equal intervals above the triangular frame 41 , the length of each adjustable-tilt photovoltaic panel 43 is the same as the frame width at the corresponding position, and the orientations of the plurality of adjustable-tilt photovoltaic panels 43 on each triangular frame 41 remain consistent.

[0028] Furthermore, the adjustable tilt photovoltaic panel 43 includes a solar photovoltaic panel 433, and 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 mounted on the triangular frame 41 through corresponding ball joint supports 431.

[0029] Furthermore, every two adjacent photovoltaic support modules 40 are connected via three frame connectors 30 , and the three frame connectors 30 are respectively connected to two end points and a midpoint of one side of the corresponding triangular frame 41 .

[0030] Furthermore, the straight line connecting the centers of the two holes of the fork structure of the cable guide connector 20 is parallel to the plane where the corresponding photovoltaic support module 40 is located.

[0031] Embodiment 2: This embodiment provides a triangular floating photovoltaic array suitable for use near the coast, such as Figure 2As 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 a 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-relaxed. The mooring anchor cable 13 is divided into two sections, one end of the mooring anchor cable 13 near the bottom of the water is connected to the cable guide point on the anchor block 11, and the other end is connected to the bottom of the spring damper, and one end of the mooring anchor cable 13 near the spring damper 12 is connected to the bottom of the double-fairlead cable 14 or the single-fairlead cable 15, and the other end is connected to the top of the spring damper 12. One end of the double-fairlead cable 14 or the single-fairlead cable 15 near the cable guide connector 20 is connected to the top of the second section of the mooring anchor cable, and the other end is connected to the cable guide connector 20.

[0032] 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, and the fork rods can rotate around the cross shaft within a certain degree. The universal joint structure of the present invention is different from the general universal joint. The other end of the fork rod is fixed on 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 cable guide connector 20 is the same as a fork rod structure of the universal joint structure of the frame connector 30, which reduces the manufacturing cost, facilitates the 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 of the fork structure is parallel to the plane where the photovoltaic support module 40 is located, so that the two holes are evenly stressed, the durability of the cable guide connector 20 is increased, and it is convenient to connect the mooring anchor cable 13.

[0033] 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 the cross-sectional shape 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. The spherical geofluid performance is better, which can improve the movement performance of the array in waves. The adjustable photovoltaic panel 43 includes four ball joint supports 431, two telescopic rods 432 connected to the ball joint supports 431, and a photovoltaic panel 433. The four ball joint supports 431 are respectively located at two symmetrical corners of the photovoltaic panel 433 and the triangular frame 41 at the corresponding position. The two telescopic rods 432 are respectively connected to 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 supports 431 and telescoping along the axial direction.

[0034] Further, such as Figure 3 As shown, the double-chock cable guide and anchor cable 14 is in a "Y" shape, and the single-chock cable guide and anchor cable 15 is in a straight line shape.

[0035] Furthermore, the double-fairguide cable anchor cable 14 is connected to two cable connectors 20 corresponding to two photovoltaic support modules 40, reducing the number of mooring devices 10 and saving costs; the single-fairguide cable anchor cable 15 is connected to a cable connector 20 corresponding to a photovoltaic support module 40, improving mooring stability.

[0036] Furthermore, the mooring anchor cable 13 passes through two holes of the fork structure of the cable guide connector 20 .

[0037] Furthermore, each photovoltaic support module 40 connected to the mooring device has three cable guide connectors 20, which are located at two end points and a midpoint of one side of the triangular frame.

[0038] 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 overall photovoltaic array.

[0039] 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.

[0040] 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.

[0041] Embodiment 3, based on the same inventive concept, this example also provides an arrangement method of the triangular floating photovoltaic array as described above, comprising the following steps: S1, take out 6 photovoltaic support modules from a total number of n to form an equilateral hexagonal array, n ≥ 6; S2, when 6<n≤12, on the basis of the photovoltaic array arranged in step S1, the remaining (n-6) photovoltaic support modules are arranged in an alternating order on the upper and lower sides of the current photovoltaic array; S3, when 12<n≤24, on the basis of the photovoltaic array arranged in step S2, the remaining (n-12) photovoltaic support modules are arranged in sequence on the left and right sides of the current photovoltaic array in an alternating order until an equilateral hexagonal array with geometric enlargement is formed; S4, when 24<n≤28, on the basis of the photovoltaic array arranged in step S3, the remaining (n-24) photovoltaic support modules are arranged in sequence on the upper side of the current photovoltaic array, until the remaining photovoltaic support modules form an equilateral triangle array on the upper side of the current photovoltaic array; S5, when n>28, based on the photovoltaic array arranged in step S3, the remaining (n-24) photovoltaic support modules are arranged into multiple equilateral triangle arrays in groups of 4, and the last group of photovoltaic support modules that is less than 4 is connected into a separate array, and then the separate array and each equilateral triangle array are regarded as a whole photovoltaic support module, and step S2 is re-executed.

[0042] Specifically, Figure 8 As shown: In order to ensure the hydrodynamic performance of the photovoltaic array, it is necessary to maintain lateral and longitudinal symmetry. Based on the hexagonal array composed of 6 photovoltaic support modules, when the total number of modules does not exceed 12, the number of photovoltaic support modules in the upper and lower rows is evenly increased on the basis of 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 evenly increased on the basis of 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 evenly increased, and when the number of modules is increased to 24, the overall shape is similar to that of 6 modules, which is geometrically enlarged.

[0043] The above method can be applied to the case of any total number of modules: based on a hexagonal array composed of 6N (N is the number of modules that can form a similar equilateral triangle, N=1, 4, 12...) photovoltaic support modules, an array with N modules increasing in arithmetic increments is constructed. If the multiple relationship cannot be satisfied, a smaller N is used to make up the difference. For example, if the total number of modules is 203, N=12 is used, and a maximum of 16n can be arranged. For the remaining 13 modules, N=4 is used to make up 8 modules, and for the remaining 3, N=1 is used to make up 3 modules.

[0044] Furthermore, all parts involved in this application that are not described in detail are the same as the prior art or are implemented using the prior art.

[0045] In summary: 1. The present invention can be applied to different coastal high and low tide environments. By maintaining the tension force through the spring damper of the mooring device, the influence of the change of the waterline height on the entire floating photovoltaic system can be reduced; 2. The structure of the present invention is stable and reliable. Each photovoltaic support module is connected by a plurality of frame connectors, and the frame of each support module adopts a stable triangular structure, so that the overall structure is stable; 3. The present invention has good wind and wave resistance. By adopting a spherical float, the hydrodynamic performance is good. By adopting a reasonable array arrangement method, the overall photovoltaic array is close to central symmetry, and the movement in wind and waves is more stable; 4. The invention has high power generation efficiency, close arrangement between modules, high space utilization rate, and adjustable inclination angle of photovoltaic panels, which can cope with the illumination angles in different seasons; the arrangement of triangular modules is flexible and suitable for different marine environments; 5. The present invention has a compact overall structure, is stable and reliable, and the cable guide connector and the frame connector adopt partially identical structures through the reasonable arrangement of mooring devices, connectors and photovoltaic support modules, which can effectively reduce the processing and manufacturing costs; and the connection between modules only needs to be fixed by a cross axis, which is convenient for installation, maintenance and promotion.

[0046] It will be easily understood by those skilled in the art that the above description is only 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 protection scope of the present invention.
