[0019] A plurality of the fan-shaped platform panels 46 are movably arranged on the outside of the shaft body 45 in sequence from top to bottom, and a second photovoltaic panel 45 is arranged on the fan-shaped platform panels 46 .

[0020] The folding structure is disposed on the shaft body 50 , and the folding structure can drive a plurality of fan-shaped platform panels 46 to unfold and fold.

[0021] When the sea is calm and the sun is abundant, several fan-shaped platform panels 46 are unfolded through the folding structure to expose all the second photovoltaic panels 45 to sunlight, thereby increasing photovoltaic power generation. In the face of severe weather and extreme sea conditions, several fan-shaped platform panels 46 are folded using the folding structure to be located between the top platform 7 and the bottom platform 9, thereby avoiding damage to the fan-shaped photovoltaic power generation mechanism 4 and reducing the maintenance cost of the power generation device. In addition, the device integrates offshore wind energy and wave energy, utilizes the complementarity of different power generation methods, realizes stable transmission power after converting ocean energy into electrical energy, and improves energy utilization efficiency.

[0022] In this embodiment, the folding structure includes a fixed sleeve 51, a rotating sleeve 42, a plurality of rotating rings 52 and a driving assembly.

[0023] The fixing sleeve 51 is fixed to the lower end of the shaft body 50 , and the fan-shaped platform plate 46 close to the bottom platform 9 is fixed to the fixing sleeve 51 .

[0024] The rotating sleeve 42 is rotatably disposed on the upper end of the shaft body 50 , and the upper end of the rotating sleeve 42 is rotatably disposed on the lower side of the top platform 7 .

[0026] The driving assembly is disposed on the shaft body 50 , and the driving assembly includes a servo motor 12 and a gear ring 49 .

[0027] The upper end of the shaft body 50 is provided with a mounting hole 47 , and the servo motor 12 is mounted in the mounting hole 47 . The output shaft of the servo motor 12 extends into the rotating sleeve 42 and a first gear 48 is disposed at the end thereof.

[0028] The first gear ring 49 is fixed on the inner wall of the rotating sleeve 42 , and the first gear 48 is meshedly connected with the first gear ring 49 .

[0029] When the folding fan-shaped platform panel 46 needs to be folded, the servo motor 12 is started, and the first gear ring 49 and the rotating sleeve 42 are driven to rotate through the first gear 48, and the folding fan-shaped platform panel 46 connected to the rotating sleeve 42 starts to rotate, and then the folding fan-shaped platform panel 46 connected to the rotating sleeve 52 below is driven to rotate in turn. Since the folding fan-shaped platform panel 46 connected to the fixed sleeve 51 is fixed, all the folding fan-shaped platform panels 46 are finally unfolded into a fan shape, thereby increasing the light-receiving area of ​​the second photovoltaic panel 45 and increasing the photovoltaic power generation.

[0030] In this embodiment, a slide slot hole 53 is provided on the folding fan type platform plate 46. Preferably, the slide slot hole 53 is waist-shaped, and a slide rod is slidably arranged in the slide slot hole 53. A connecting rod 43 is hinged on the adjacent folding fan type platform plate 46. One end of the slide rod is fixedly connected to the free end of the connecting rod 43, and a limiting sealing plate is provided on the other end of the slide rod. The size of the limiting sealing plate is larger than the width of the slide slot hole 53.

[0031] When the rotating sleeve 42 drives the top folding fan-shaped platform plate 46 to rotate, the connecting rod 43 drives the adjacent folding fan-shaped platform plate 46 below to rotate as well. The slide slot hole 53 can control the movable range of the connecting rod 43, so that the two adjacent folding fan-shaped platform plates 46 are staggered up and down when unfolded, thereby increasing the light-receiving area of ​​the second photovoltaic panel 45.

[0032] In this embodiment, the folding fan-shaped platform plate 46 on the rotating sleeve 42 is equipped with a stop bar 44, and the lower end of the stop bar 44 extends to be flush with the fixed sleeve 51. When all the folding fan-shaped platform plates 46 need to be folded, the servo motor 12 is started to rotate in the opposite direction, and the first gear ring 49 and the rotating sleeve 42 are driven to rotate in the opposite direction through the first gear 48, and the stop bar 44 contacts all the unfolded folding fan-shaped platform plates 46 in turn, and then pushes them to fold each other. When the stop bar 44 finally contacts the folding fan-shaped platform plates 46 on the fixed sleeve 51, all the folding fan-shaped platform plates 46 are in a vertical row, and the folding work is completed.

[0033] Preferably, the shaft body 50 is vertically rotatably arranged on the bottom platform 9, a second gear ring 56 is fixedly provided at the lower end of the shaft body 50, a driving motor 54 is provided on the bottom platform 9, a second gear 55 is provided on the output shaft of the driving motor 54, and the second gear 55 is meshingly connected with the second gear ring 56.

[0034] In order to protect the folding fan-shaped platform panels 46 as much as possible, in the folded state, the folding fan-shaped platform panels 46 in a vertical row can all enter between the top platform 7 and the bottom platform 9 to reduce the impact of wave protection on them. At this time, the second gear 55 and the second gear ring 56 can be driven by the driving motor 54 to rotate, and then the shaft body 50 rotates to rotate the folding fan-shaped platform panels 46 connected to the fixed sleeve 51 to between the top platform 7 and the bottom platform 9. At the same time, when it is necessary to unfold all the folding fan-shaped platform panels 46, the folding fan-shaped platform panels 46 connected to the fixed sleeve 51 can be rotated to the outside of the top platform 7, so that all the folding fan-shaped platform panels 46 can be exposed to the sunlight after unfolding, thereby increasing the power generation of the second photovoltaic panel 45.

[0035] When the device is operating normally, the folding fan-shaped platform plate 46 connected to the fixed sleeve 51 rotates outward to expose the top platform 7, and then the servo motor 12 is used to drive the folding fan-shaped platform plate 46 connected to the rotating sleeve 42 to rotate clockwise, and the adjacent folding fan-shaped platform plates 46 are driven by the connecting rod 43 to reach a preset angle, and the folding fan-shaped photovoltaic panel 46 is fully unfolded, and together with the first photovoltaic panel 8 on the top platform 7, it converts light energy into electrical energy; the wave energy power generation float 6 is controlled by the internal device and automatically descends to the sea surface 10, and the wave energy power generation float 6 moves up and down with the waves to convert mechanical energy into electrical energy; the wind turbine blades 2 are unlocked, and the power generation device in the main cabin 1 is used to convert wind energy into electrical energy. The combination of the three energy sources can better improve the energy utilization efficiency and overcome the shortcomings of using each energy separately.

[0036] The wave energy power generation buoy 6 and the main engine room 1 are both conventional products for utilizing existing wave energy and wind energy.

[0037] When the sea area where the device is located encounters severe weather and extreme sea conditions, the folding fan-shaped platform plate 46 connected to the fixed sleeve 51 rotates inward to enter under the top platform 7, and then the servo motor 12 drives the folding fan-shaped platform plate 46 connected to the rotating sleeve 42 to rotate counterclockwise, and the adjacent folding fan-shaped platform plates 46 are driven by the connecting rod 43, and all the folding fan-shaped platform plates 46 are recovered into the interlayer between the top platform 7 and the bottom platform 9 to prevent damage; the wave energy power generation float 6 is controlled by its internal device and automatically lifted away from the sea surface 10 to the bottom of the lower platform to prevent damage to it by extreme sea conditions; wherein the fan blades 2 are internally locked in severe sea weather to prevent damage to it by severe weather. Through these self-protection methods, the adverse effects of severe weather and extreme sea conditions on the device can be greatly reduced, and the operation and maintenance costs of the equipment can be reduced.
