Description

Technical Field

[0001] The present invention relates to the technical field of development and utilization of marine renewable energy, and in particular to a comprehensive platform integrating deep-sea aquaculture and thin-film photovoltaic power generation. Background Art

[0002] At present, under the pressure of the sharp increase in electricity demand, countries are actively exploring new renewable energy development technologies such as wind energy, hydrogen energy and solar energy. With the active response of domestic coastal provinces and cities to policies, offshore floating photovoltaic power generation technology is becoming more and more innovative, and the commercial application of offshore floating photovoltaics is vigorously promoted, making it one of the innovative technologies in the field of new energy development. Thanks to the excellent cooling performance of seawater on photovoltaic modules, the power generation of offshore photovoltaics is higher than that on land. Existing floating photovoltaic power generation is mainly concentrated in coastal areas with relatively stable wind and waves. Floating photovoltaic technologies include array pontoon type and semi-submersible truss type. Due to the low photoelectric conversion efficiency of photovoltaic modules (about 24%), large-scale power generation needs to be achieved by multi-array arrangement. As the offshore photovoltaic deployment area becomes increasingly saturated, exploring new, safe and efficient offshore renewable energy power generation technologies in deeper and farther waters is a cutting-edge issue that the world is focusing on. Floating thin-film photovoltaic power generation is suitable for deep sea areas and has excellent wave-following performance. However, existing thin-film photovoltaics mostly use tensioned or catenary mooring methods, which cannot cope with complex and harsh sea conditions. How to improve the wind and wave resistance, survivability and economic benefits of power generation platforms in deep sea conditions is an issue that urgently needs to be considered.

[0003] In recent years, in order to expand the space for the development of marine fisheries and improve their quality, marine aquaculture has gradually moved from harbors and nearshore areas to deep and open seas.

[0004] Therefore, exploring diversified, efficient and sustainable power generation applications in deep sea areas and planning deep sea aquaculture and renewable energy utilization technologies are of great strategic significance for my country to achieve its "dual carbon" goals and promote the fishery economy and diversified development of deep sea resources. Summary of the invention

[0005] In view of the increasingly scarce sea areas available for offshore floating photovoltaics, the shortcomings of offshore floating photovoltaics such as weak wind and wave resistance, poor survivability, low economic benefits and great difficulty in operation and maintenance in complex sea conditions in the deep sea, the present invention proposes a comprehensive platform integrating deep-sea aquaculture and thin-film photovoltaic power generation. The thin-film photovoltaic power generation platform is arranged on the deep-sea aquaculture cages, which has good wave-following performance and can ensure that the platform can operate continuously, stably and efficiently in complex sea conditions in the deep sea.

[0009] In the above scheme, a rack-shaped groove is provided on the side of the floating tube of the thin-film photovoltaic module located at the head end, and the lifting drive mechanism is installed on the deep-sea aquaculture cage. A gear is installed on the output end of the lifting drive mechanism, and the gear is engaged with the rack-shaped groove. The gear is driven to rotate by the lifting drive mechanism, thereby driving the folded thin-film photovoltaic power generation platform as a whole to move downward below the water surface.

[0010] In the above scheme, the external turret mooring system includes a top platform, a turret, a mooring bollard, a base and a cable; the top platform is at a certain height from the sea surface to facilitate the deployment of a rectifier energy storage device, a meteorological observation instrument and a data sensor; the turret is located below the top platform and is used to connect the rear structure to form a single-point mooring, so that the entire integrated platform can rotate 360° horizontally around the external turret mooring system; the base is arranged below the turret to provide buoyancy; a plurality of mooring bollards are installed around the base; one end of the cable is tied to the mooring bollard by a catenary mooring method, and the other end is tied to a suction anchor and fixed to the seabed.

[0016] In the above scheme, the cage module of the deep-sea aquaculture cage is composed of a flexible net, and a fishing net is nested in the flexible net.

[0017] The beneficial effects produced by the present invention are:

[0018] 1. The present invention arranges the thin-film photovoltaic power generation platform on the deep-sea aquaculture cage. The thin-film photovoltaic panel has good wave-following performance, which can ensure that the photovoltaic power generation platform can operate continuously, stably and efficiently under complex sea conditions in the deep sea.

[0020] 3. The present invention combines an oscillating float wave energy power generation device with a pendulum plate wave energy power generation device and arranges them at the head end of a photovoltaic power generation platform, and connects them to an outer turret mooring system and a deep-sea aquaculture cage through a rigid connecting rod. This arrangement design method can effectively reduce the impact of waves directly acting on the photovoltaic platform while narrowing the gap between the power generation devices and not affecting the power generation efficiency of the wave energy device, making the platform movement response softer, thereby reducing the adverse effects of severe sea conditions on fish schools.

[0021] 4. The present invention integrates two different power generation modes of wave energy power generation devices, photovoltaic power generation platforms and deep-sea aquaculture technologies to build a diversified renewable energy integration platform suitable for complex sea conditions in various sea areas, providing new ideas for exploring innovative application technologies of deep-sea new energy, and promoting the establishment of a green economic system for deep-sea fisheries and renewable energy.

As shown Figure 6-9 As shown, during fishing or feeding operations, several thin-film photovoltaic modules are folded toward the head end in a zigzag manner under the drive of the folding drive mechanism and gathered at the head end of the deep-sea aquaculture cage 50, and then moved downward as a whole to below the water surface under the drive of the lifting drive mechanism.

[0043] The connecting rods of the thin-film photovoltaic power generation platform 40 are the 1st, 2nd, ..., nth from the head end to the tail end of the deep-sea aquaculture cage 50; the folding drive mechanism is installed at the end of the connecting rod with an odd number to drive the corresponding connecting rod to rotate upward, and the end of the last connecting rod is not provided with a folding drive mechanism; the deep-sea aquaculture cage 50 is provided with a slide rail arranged along the head and tail direction, and a slider is provided on the slide rail.

Figure 5As shown, in this embodiment, there are eight cage modules and eight thin-film photovoltaic modules, which are arranged symmetrically in two rows along the width direction and four in each row along the length direction, from the head end to the tail end, they are the first thin-film photovoltaic panel 411, the second thin-film photovoltaic panel 412, the third thin-film photovoltaic panel 413, and the fourth thin-film photovoltaic panel 414. There are five connecting rods in total, from the head end to the tail end, they are the first connecting rod 431, the second connecting rod 432, the third connecting rod 433, the fourth connecting rod 434, and the fifth connecting rod 435, wherein the folding drive mechanism of the first connecting rod 431 is fixedly mounted on the deep-sea aquaculture cage 50, and the folding drive mechanism of the third connecting rod 433 is mounted on the slider. See more Figure 6-7 When fishing or feeding operations are performed, the folding drive mechanism of the first connecting rod 431 drives the first connecting rod 431 to rotate, thereby driving the first thin-film photovoltaic panel 411, the second connecting rod 432 and the second thin-film photovoltaic panel 412 to be lifted upward, and driving the third connecting rod 433 and its folding drive mechanism to slide along the slide rail toward the head end; at the same time, the folding drive mechanism of the third connecting rod 433 drives the third connecting rod 433 to rotate, thereby driving the third thin-film photovoltaic panel 413, the fourth connecting rod 434 and the fourth thin-film photovoltaic panel 414 to be lifted upward, and driving the fifth connecting rod 435 and the slider at its end to slide along the slide rail toward the head end, and finally the four thin-film photovoltaic panels form a folded state and gather at the head end of the deep-sea aquaculture cage 50.

[0053] As a further optimization, the cage module of the deep-sea aquaculture cage 50 is made of a flexible net, in which a fishing net is nested, so that the staff can pull the net between the aisle and the module to catch the fish.
