Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, and in particular to a photovoltaic-fishery joint development platform based on flexible thin-film photovoltaics. Background Technology

[0002] The global ocean covers approximately 360 million square kilometers, accounting for 70.8% of the Earth's total surface area. It contains abundant chemical, mineral, and biological resources, making it a treasure trove waiting to be explored. The history of marine resource development can be traced back more than 2,000 years, when people were already utilizing marine biological resources such as fish, shellfish, seaweed, and salt in nearshore and shallow waters. However, with the increasing demand for mineral resources and energy, large-scale marine development and utilization activities have become increasingly active, and a large number of marine development industries are emerging, including deep-sea aquaculture and offshore renewable energy development. With the development of marine aquaculture equipment technology, marine aquaculture is gradually moving towards the deep sea, and deep-sea aquaculture equipment is developing towards large-scale, intelligent, and green directions.

[0003] Currently, conventional deep-sea aquaculture equipment and floating thin-film photovoltaic systems have the following problems:

[0004] Deep-sea aquaculture offers advantages such as large aquaculture space and less water pollution, but it also faces challenges such as long distances from shore and difficulties in resupply. Currently, most marine aquaculture equipment relies on diesel generators, which presents problems such as transportation difficulties, significant pollution, and high operation and maintenance costs. Meanwhile, the biggest challenge for floating thin-film photovoltaic equipment operating at sea is the accumulation of water on the membrane by waves. Furthermore, mooring accounts for a large portion of the manufacturing cost of various marine engineering equipment; therefore, reasonable joint development can significantly reduce equipment manufacturing costs, shorten the cost recovery period, and achieve a synergistic effect greater than the sum of its parts.

[0005] Therefore, those skilled in the art are dedicated to developing a photovoltaic-fishery joint development platform based on flexible thin-film photovoltaics, which can power aquaculture cages using thin-film photovoltaics without causing water accumulation on the film. Summary of the Invention

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is the difficulty in energy supply for aquaculture cages and the susceptibility of thin-film photovoltaics to water accumulation on the film.

[0007] To achieve the above objectives, the present invention provides a solar-fishery joint development platform based on flexible thin-film photovoltaics, characterized in that it includes a net cage, a wave-damping device, and flexible thin-film photovoltaic equipment, wherein the upper part of the net cage is cylindrical and the lower part of the net cage is conical; the wave-damping device is disposed on the outer circumference of the net cage; and the flexible thin-film photovoltaic equipment is disposed at the upper opening of the net cage.

[0008] Furthermore, the opening of the cage faces upward and is above the waterline.

[0009] Furthermore, the wave-damping device is located at the waterline and includes a first large float, a wave-damping plate, and a first small float.

[0010] Furthermore, the wave-damping plate is in the shape of a flat annulus, with the first large float located on the outer side of the wave-damping plate and the first small float located on the inner side of the wave-damping plate.

[0011] Furthermore, the cage is provided with multiple vertical posts, and the first small float passes through the vertical posts for fixation.

[0012] Furthermore, a third small float is provided above the first small float; the third small float is connected to the wave-damping plate through a fixed bracket.

[0013] Furthermore, the flexible thin-film photovoltaic equipment includes a second large float, a flexible thin film, and a second small float; the flexible thin film is located between the second large float and the first small float; and a flexible photovoltaic panel is disposed on the flexible thin film.

[0014] Furthermore, the second large float is connected to the cage via eight sets of evenly distributed flexible anchor chains.

[0015] Furthermore, the second small float is connected to the net cage via a frustum-shaped net.

[0016] Furthermore, the solar-fishery joint development platform is anchored to the seabed via a mesh mooring system.

[0017] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0018] 1. This invention utilizes thin-film photovoltaics to provide energy for aquaculture cages, enabling the cages to achieve energy self-sufficiency, reducing the frequency of maintenance of maintenance vessels, lowering maintenance costs, and reducing pollution of the deep-sea environment caused by the combustion of fossil fuels; at the same time, thin-film photovoltaics provide sunlight shading for farmed fish, reducing unnecessary exposure to sunlight;

[0019] 2. This invention deploys thin-film photovoltaics on the water surface of aquaculture cages. Taking advantage of the larger mass and stronger wave resistance of aquaculture cages, it provides good wave shielding for thin-film photovoltaics, while reducing the occurrence of waves and water accumulation.

[0020] 3. The thin-film photovoltaic system of the present invention shares a mooring system with the aquaculture cage, which can greatly reduce the equipment manufacturing cost.

[0021] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Attached Figure Description

[0027] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0028] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a solar-fishery joint development platform based on flexible thin-film photovoltaics, which consists of a net cage 1, a wave-damping device, and flexible thin-film photovoltaic equipment.

[0030] The net cage 1 is the main floating structure, with a cylindrical body and a conical lower side to maximize the volume of water in the net cage aquaculture. A wave-damping device is installed on the outer side of the net cage 1 at the waterline, consisting of a large first float 2, a wave-damping plate 3, and a small first float 4. The wave-damping plate 3 is a flat, circular ring. The large first float 2 is located outside the wave-damping plate 3, and the small first float 4 is located inside the wave-damping plate 3. The small first float 4 is fixed by passing through the vertical column of the net cage. To increase the out-of-plane rigidity of the float and enhance the wave-damping and anti-wave-rushing effect, the wave-damping plate 3 is fixed to the upper small first float 6 by a fixing bracket 5.

[0031] The flexible thin-film photovoltaic equipment consists of a second large float 7, a flexible thin film 8, and a second small float 9 connected together. Flexible photovoltaic panels are arranged on the flexible thin film 8. The second large float 7 is connected to the net cage 1 via eight sets of evenly distributed flexible anchor chains 10, ensuring that the flexible thin-film photovoltaic system has a certain degree of freedom of out-of-plane movement while controlling its relative in-plane movement with the net cage 1, preventing collisions with the side nets. The second small float 9 is connected to the net cage 1 via a frustum-shaped net 11. This design prevents farmed fish from colliding with the flexible thin film 8 from below, and also leaves space in the central water area for aeration of farmed fish and fishing during the harvest season. Furthermore, it helps maintain a certain shape at the top of the net cage 1 and further controls the relative in-plane movement of the flexible thin-film photovoltaic system and the net cage 1.

[0032] like Figure 4 As shown, the integrated solar-fishery co-development platform is anchored to the seabed by a grid mooring system. The grid mooring system can be further used for the intensive production of multiple solar-fishery co-development platforms, and adjacent development platforms can also share anchor points, further reducing equipment manufacturing costs.

[0033] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
