TECHNICAL FIELD

[0001] The utility model belongs to the field of marine disaster prevention and mitigation and marine fishery production, and particularly relates to a multi-layer three-dimensional fish reef combined with a double-deck breakwater and a floating artificial fish reef. BACKGROUND

[0002] For the sea area most seriously affected by typhoon disasters, extreme wind waves seriously affect the overall stability of the island reef fill body and the aquaculture facilities, and cause strong erosion to the shoreline, which brings disastrous influence to the resource conservation and fishery culture of the island reef. Therefore, based on disaster prevention and mitigation, ecological environmental protection and resource application, developing the island reef comprehensive development technology, complementing the advantages of the breakwater and the ecological fish reef, has important engineering significance for alleviating the depletion of fishery resources, improving the ecological environment of the island reef sea area, and protecting the integrity of the marine island reef shoreline and long-term service performance.

[0003] The artificial fish reef is a key link in the construction of the marine ranch, which can change the living environment of fish and shellfish in the sea and reduce the traditional predatory trawl operation. The floating fish reef has the characteristics of not being limited by water depth, makes up for the shortcomings of the marine ranch bottom fish reef in lacking influence on the upper water body of the sea, and can play an important role in the construction of the deep-sea ocean ranch: forming a middle and upper layer fishing ground; proliferating and conserving pelagic organisms; improving the amount of fishery biological resources and the ability of sustainable development; and improving the utilization level of biological resources in the sea area around the island reef.

[0004] The double-deck breakwater can well adapt to changing water levels, facilitate seawater exchange in different regions, be beneficial to the diffusion and purification of local pollutants, to a certain extent, can play a role in protecting the quality of seawater, and is helpful to the combination with the marine fishery structure. Meanwhile, the structure is simple, has no special requirements on technology, and has low production cost, so it is convenient for large-scale production.

[0005] A structure combining a breakwater and an ecological fish reef is needed to take into account the wave protection and marine fishery production functions. Utility model content

[0006] To solve the above problems, the utility model provides a floating artificial fish reef, which is a novel multi-layer three-dimensional structure combining a breakwater and an artificial fish reef, and has the functions of wave protection and rich marine fishery resources in addition to the wave protection function.

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

[0008] A multi-layer three-dimensional fish reef combined with a double-deck breakwater and a floating artificial fish reef, comprising a top panel 1, a double-deck breakwater 2 and a floating artificial fish reef 3.

[0009] The double-layer plate breakwater 2 comprises an upper layer plate and a lower layer plate, and the two layers are connected through rigid support columns; the top plate 1 is located above the upper layer plate and is connected through rigid support columns.

[0010] The floating artificial fish reef 3 is connected to the bottom surface of the lower layer plate through flexible connecting ropes at the top, and is provided with a mooring line 6 at the bottom, which is used to moor the multi-layer three-dimensional fish reef combined by the double-layer plate breakwater and the floating artificial fish reef to a mooring point 7.

[0011] The edges of the top plate 1 and the upper layer plate and the lower layer plate of the double-layer plate breakwater 2 are all provided with a connecting system 8, which is used to connect the multi-layer three-dimensional fish reef combined by multiple double-layer plate breakwaters and floating artificial fish reefs, and to combine single bodies into multiple bodies.

[0012] The top plate 1 is a regular hexagon; the upper layer plate and the lower layer plate in the double-layer plate breakwater 2 are both regular hexagons; and the floating artificial fish reef 3 is a regular hexagonal prism frame structure, and one or more openings are symmetrically arranged on each side surface, and the number and size of the openings are determined according to the size of fish.

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) The main body is designed in a hexagonal structure, and the double-layer plate breakwater with the hexagonal structure has good wave breaking and shore protection effects on cross waves and oblique waves, and can be flexibly assembled into a multiple body structure according to local sea current characteristics.

[0015] (2) The floating artificial fish reef has obvious advantages in the protection of upper-middle layer fishery in a sea area with large water depth, and can be jointly constructed with a bottom-sinking fish reef, thereby breaking the shackles of the traditional bottom-sinking fish reef limited by the water depth of a sea area and expanding the application and construction range of the artificial marine ranch.

[0016] (3) The breakwater has obvious wave energy dissipation effect, can slow down the flow velocity to generate a flow field, has the function of an artificial fish reef to a certain extent, and the floating artificial fish reef also has the effect of promoting wave breaking. The combination of the breakwater and the floating artificial fish reef is beneficial to the construction of an integrated ecological wave breaking structure.

[0017] (4) The function is relatively diverse, the structure is ecological and friendly, and the marine space is effectively utilized. The breakwater is combined with the demand of marine fishery on the surface of the sea, the added value of the breakwater structure is improved, and the sustainable development of marine fishery is promoted.
