Description

Technical Field

[0001] The present invention relates to the technical field of marine aquaculture, and in particular to a light-fishing joint development platform based on flexible thin-film photovoltaics. Background Art

[0002] The global ocean area is about 360 million square kilometers, accounting for 70.8% of the total area of ​​the earth. It contains rich chemical resources, mineral resources, biological resources, etc. It is a treasure trove that is waiting to be explored. The history of the development of the world's marine resources can be traced back to more than 2,000 years ago, when people had already used 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 more active, and a large number of marine development industries are in the ascendant, including deep-sea aquaculture and offshore renewable energy development industries. With the development of marine aquaculture equipment technology, marine aquaculture is gradually moving towards the deep sea, and deep-sea aquaculture equipment is developing in the direction of large-scale, intelligent, and green.

[0003] At present, conventional deep-sea aquaculture equipment and floating thin-film photovoltaics have the following problems:

[0004] Deep-sea aquaculture has advantages such as large aquaculture space and less pollution to aquaculture water, but it also faces problems such as long distance from shore and difficulty in replenishment. At present, most marine aquaculture equipment relies on diesel power generation, which has problems such as difficult transportation, high pollution, and high operation and maintenance costs; and the biggest challenge for floating thin-film photovoltaic equipment when working at sea is the problem of water accumulation on the film due to waves. In addition, mooring accounts for a large part of the manufacturing cost of various marine engineering equipment. Reasonable joint development will greatly reduce the equipment manufacturing cost and the cost recovery cycle, achieving the effect of 1+1>2.

[0005] Therefore, technicians in this field are committed to developing a light-fishing joint development platform based on flexible thin-film photovoltaics, which can rely on thin-film photovoltaics to power aquaculture cages without causing problems such as waves and 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 that the energy supply of the aquaculture cage is difficult and the thin-film photovoltaic is susceptible to water accumulation on the film due to waves.

[0007] To achieve the above-mentioned purpose, the present invention provides a light-fishing joint development platform based on flexible thin-film photovoltaics, characterized in that it includes a cage, a wave-breaking device, and flexible thin-film photovoltaic equipment, wherein the upper part of the cage is cylindrical and the lower part of the cage is conical; the wave-breaking device is arranged on the outer side of the circumference of the cage; and the flexible thin-film photovoltaic equipment is arranged at the upper opening of the cage.

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

[0009] Furthermore, the wave-breaking device is located at the water plane, and includes a first large floating ring, a wave-breaking plate, and a first small floating ring.

[0010] Furthermore, the wave-breaking plate is in a flat annular shape, the first large floating ring is located on the outer side of the wave-breaking plate, and the first small floating ring is located on the inner side of the wave-breaking plate.

[0011] Furthermore, a plurality of vertical columns are distributed on the net box, and the first small floating ring passes through the vertical columns for fixation.

[0012] Furthermore, a third small floating ring is arranged above the first small floating ring; the third small floating ring is connected to the wave-breaking plate through a fixed bracket.

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

[0014] Furthermore, the second large floating ring is connected to the cage through 8 groups of evenly distributed flexible anchor chains.

[0015] Furthermore, the second small floating ring is connected to the net box through a truncated cone-shaped net.

[0016] Furthermore, the light-fishing joint development platform is anchored to the seabed through a grid mooring system.

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

[0018] 1. The present invention uses thin-film photovoltaics to provide energy supply for aquaculture cages, so that the cages can achieve energy self-sustaining, reduce the frequency of operation and maintenance of operation and maintenance ships, reduce operation and maintenance costs, and reduce the pollution of the deep-sea environment caused by the burning of fossil energy; at the same time, thin-film photovoltaics provide sunlight shielding for farmed fish to reduce unnecessary exposure to the sun;

[0019] 2. The present invention arranges thin-film photovoltaics on the water surface of the aquaculture cages, and takes advantage of the characteristics of the aquaculture cages with greater mass and stronger wave resistance to provide good wave shielding effect for the thin-film photovoltaics, while reducing the occurrence of waves and water accumulation;

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

[0021] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following describes several preferred embodiments of the present invention with reference to the drawings in the specification, so that the technical content is clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0028] In the drawings, components with the same structure are indicated by the same numerical reference numerals, and components with similar structures or functions are indicated by similar numerical reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present invention does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of the components is appropriately exaggerated in some places in the drawings.

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

[0030] The cage 1 is the main floating structure, with a cylindrical main body and a conical lower side to maximize the volume of the cage aquaculture water body. A wave-breaking device is arranged on the outer side of the waterline of the cage 1, which is composed of a first large floating ring 2, a wave-breaking board 3, and a first small floating ring 4. The wave-breaking board 3 is in a flat circular ring shape, the first large floating ring 2 is located on the outer side of the wave-breaking board 3, and the first small floating ring 4 is located on the inner side of the wave-breaking board 3. The first small floating ring 4 passes through the vertical column of the cage for fixing. In order to increase the out-of-plane motion stiffness of the floating ring and enhance the wave-breaking and wave-prevention effects, the wave-breaking board 3 is fixed to the third small floating ring 6 above through a fixing bracket 5.

[0031] The flexible thin-film photovoltaic equipment is connected by the second large floating ring 7, the flexible film 8 and the second small floating ring 9. The flexible photovoltaic panel is arranged on the flexible film 8. The second large floating ring 7 is connected to the cage 1 through 8 sets of evenly distributed flexible anchor chains 10, ensuring that the flexible thin-film photovoltaic can control the relative in-plane movement with the cage 1 while having a certain degree of freedom of out-of-plane movement to prevent collision with the side net. The second small floating ring 9 is connected to the cage 1 through a truncated cone-shaped net 11. This design can prevent farmed fish from hitting the flexible film 8 from below, and can also leave space in the central water area for convenient ventilation of farmed fish and fishing during the harvest period. In addition, it can help the upper part of the cage 1 maintain a certain shape and further control the relative in-plane movement of the flexible thin-film photovoltaic and the cage 1.

[0032] like Figure 4 As shown, the overall optical-fishery joint development platform is anchored to the seabed through a grid-type mooring system. The grid-type mooring system can be further used for the intensive production of multiple optical-fishery joint development platforms. Adjacent development platforms can also share anchor points, further reducing equipment manufacturing costs.

[0033] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
