TECHNICAL FIELD

[0001] The utility model belongs to the field of marine disaster prevention and reduction and marine fishery production, concretely relates to a multi-layer three-dimensional net cage combined with a double-layer circular arc plate breakwater and a seawater culture net cage. BACKGROUND

[0002] The ocean has abundant resources, and the research and exploration of marine resource development and utilization has been a hot topic. With the increase of the scale of marine utilization and development in recent years, marine engineering gradually develops from shallow water to medium and deep water, and the erosion of marine wind and waves on marine engineering structures and island coastlines is paid more and more attention. Based on the requirements of reducing the wave force on marine engineering structures and wave reflection, ecological sustainable development, further development and utilization of marine resources, the structure of the breakwater and the culture net cage is integrated, which has important practical significance for protecting the integrity of marine engineering structures and long-term service performance, increasing marine fishery resources, and improving the ecological environment stability of island coastlines.

[0003] The seawater culture net cage is a key link in marine farming and stockbreeding construction, which can change the traditional predatory trawl operation into aquaculture, artificially create the survival environment of economic crops in the ocean, and reduce the destructive development of marine fishery resources. The seawater culture net cage has the characteristics of high recognition and low installation cost, which makes up for the high initial investment cost of artificial fish reefs, and can play an important role in marine farming and stockbreeding construction: improving the utilization level of biological resources in the coastal waters; proliferating and protecting common aquatic economic animals and plants; and improving the sustainable development ability of regional fishery and the biological resource threshold.

[0004] The double-layer circular arc plate breakwater facilitates water exchange between the inner and outer areas of the breakwater, can reduce the impact on the coastal water quality and marine ecological function, can provide suitable water quality conditions for marine economic animals and plants to grow and reproduce to a certain extent, and is helpful to the combination with marine farming and stockbreeding construction. At the same time, the structure is convenient to build, lay and remove, has low requirements for local seabed geological conditions, does not require special technology, has low cost, and is convenient for industrialized layout.

[0005] A structure combining a breakwater and a culture net cage is needed to take into account the wave protection and the role of enriching marine fishery resources. Utility model content

[0006] To solve the above problems, the utility model provides a seawater culture net cage, which is a new type of multi-layer three-dimensional structure combining a breakwater and a culture net cage, and has the functions of marine fishery production in addition to the functions of wave protection and disaster reduction.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A double-layer arc plate breakwater and seawater aquaculture net cage combined multi-layer three-dimensional net cage, comprising a top panel 1, a double-layer arc plate breakwater 3, a frame reinforcing structure 5 and a seawater aquaculture net cage 6.

[0009] The double-layer arc plate breakwater 3 comprises an upper layer plate and a lower layer plate, both of which are arc plates, and the two layers are connected by rigid support columns 2; the top panel 1 is located above the upper layer plate and is connected by rigid support columns 2.

[0010] The seawater aquaculture net cage 6 is a net structure and is fixed as a whole on the frame reinforcing structure 5; the frame reinforcing structure 5 has its top part located below the lower layer plate and connected to the bottom surface of the lower layer plate by flexible connecting ropes 4, and has a plurality of first mooring chains 7 arranged at its bottom part for mooring the double-layer arc plate breakwater and seawater aquaculture net cage combined multi-layer three-dimensional net cage to second mooring chains 8, and the whole structure is moored to a mooring point 9 by the second mooring chains 8.

[0011] The edges of the top panel 1 and the upper layer plate and the lower layer plate of the double-layer arc plate breakwater 3 are all provided with a connecting system 10 for connecting a plurality of double-layer arc plate breakwaters and seawater aquaculture net cage combined multi-layer three-dimensional net cages to form a multi-body structure from a single-body structure.

[0012] The top panel 1 is rectangular; the upper layer plate and the lower layer plate of the double-layer arc plate breakwater 3 are arc plates and their vertical projections are both rectangular; the frame reinforcing structure 5 is a cuboid frame structure; and the seawater aquaculture net cage 6 is a cuboid net structure, and the size of the net of the aquaculture net cage is determined according to the type and size of the cultured objects.

[0013] The utility model discloses the beneficial effects of:

[0014] (1) the main body is designed by adopting the rectangular structure, since the single body is the rectangular structure, the double-layer arc plate breakwater with this structure has the characteristics of being densely laid, can play a good wave cutting effect on the wave, and can be properly assembled to better adapt to the ocean current parameters of the installation site.

[0015] (2) the seawater aquaculture net cage is selected, so that the aquatic economic plants and animals can be artificially bred and fished in the upper and middle sea areas, and the seawater aquaculture net cage can be jointly constructed with the artificial fish reefs to complement each other's advantages and increase the diversity of marine farming and husbandry construction.

[0016] (3) the function is relatively diverse, and the seawater aquaculture net cage has the advantages of marine farming and husbandry and efficient use of marine three-dimensional space. The disaster prevention and mitigation and the demand of marine aquaculture are combined in the marine shallow water layer, which promotes the sustainable development of marine farming and husbandry, improves the economic benefit of the breakwater structure.

[0017] (4) The main function of the breakwater is to dissipate the energy of non-periodic waves, which objectively reduces the energy of the waves and generates a slow flow field in the sea area near the breakwater, which indirectly provides a living environment for marine plants and animals, and facilitates the positioning of the mariculture net cage on the sea surface. The mariculture net cage can also enhance the stability of the breakwater and reduce the degree of drift of the breakwater structure. The combination of the breakwater and the mariculture net cage can better construct the marine farming and breeding structure. BRIEF DESCRIPTION OF DRAWINGS
