The utility model relates to the technical field of fish reefs, in particular to an upflow artificial fish reef.

Background technique

Since the 1980s, due to overfishing and environmental pollution, especially the high-intensity operation of lethal fishing gear such as bottom trawling, the ecological environment of my country's offshore fisheries has deteriorated and fishery resources have declined. In view of the above problems, it is imperative to take measures to improve the marine environment and resources. Among them, putting artificial reefs in the offshore to improve the marine ecological environment has achieved good results. Putting artificial reefs is very important for restoring and protecting offshore fishery resources, improving The coastal ecological environment has played a very important role. The development of artificial reefs has great strategic and far-reaching historical significance for restoring and improving the marine ecological environment, protecting biodiversity, and promoting the sustainable and healthy development of the marine economy.

Although there are many kinds of existing artificial reefs, they are mainly aimed at providing places for fishes to breed, grow, bait, and shelter enemies. Thus, the emergence of thermocline and halocline in the sea area slows down the vertical exchange of water bodies and forms an anoxic layer on the seabed, which easily leads to the death of sea cucumbers and other aquatic organisms. Therefore, how to improve the upwelling effect of the artificial reef is a problem that we should further solve.

Contents of the invention

The purpose of the utility model is to provide an upwelling artificial fish reef, which can provide necessary and safe habitats for the gathering, baiting, breeding, growth and avoiding enemies of aquatic organisms such as fish, and it can also generate upwelling, It can change the distribution of the flow field in the sea area, drive the exchange of nutrients from the bottom layer with the upper water body, provide nutrients for the reproduction and growth of plankton in the upper water body, create a good habitat for marine organisms, and enhance the reproduction and reproduction of plankton. An excellent bait field attracts the gathering and retention of migratory fish, and achieves a better fish gathering effect. At the same time, it can effectively prevent the clogging of the reef during use, and the upwelling generated by the current flowing through the lower body of the reef can Drive the seawater flow in the body cavity on the reef, clean up the sediment in the body cavity on the reef, and ensure the survival and reproduction space of fish and other aquatic organisms, so as to achieve the purpose of protecting, adding value to fishery resources and increasing catches.

The purpose of the utility model is achieved through the following technical solutions: it is composed of the upper body of the fish reef, the lower body of the fish reef, a support column and the base, and the upper body of the fish reef is an internal hollowed-out boss structure with concave curved surfaces on each side, Each surface of the upper body of the fish reef is provided with through holes, and the lower body of the fish reef is an internal hollow convex platform structure with concave curved surfaces on each side, the lower body of the fish reef is fixed on the base, and the lower body of the fish reef The upper surface is provided with a through hole, and the through hole on the bottom surface of the upper body of the reef is opposite to the through hole on the lower body of the reef, and the support column is fixed on the base to support the upper body of the reef, and the surface of the base is provided with through hole.

Notable features of the utility model are:

The upper body of an upwelling artificial fish reef is a hollowed-out boss structure, which can effectively use the ocean current. When the ocean current flows through the upper body of the fish reef, the boss structure can effectively reduce the loss of water flow. It is conducive to increasing the height of the upwelling, making the nutrients deposited on the seabed rise, driving the exchange of nutrients at the bottom with the upper water, providing nutrients for the reproduction and growth of plankton in the upper water, creating a good habitat for marine organisms, and achieving a better environment. At the same time, a large-scale back vortex is formed on the side and back of the upper body of the reef, providing various flow field environments for different fish.

The side of the upper body of the fish reef of an upwelling artificial fish reef is a concave curved surface, which can further reduce the loss of water flow force on the upper body of the fish reef as the upstream surface, and the water flows upward along the upper body of the fish reef During the process, the concave curved surface plays the role of diverting the water flow upwards, reducing the horizontal flow of the water flow to both sides of the reef, thereby increasing the flow and height of the upwelling, and making the nutrients deposited on the seabed rise.

The lower body of an upwelling artificial fish reef is an internal hollow convex platform structure with concave curved surfaces on each side. The convex platform structure helps the formation of upwelling, and the concave curved surface can reduce the loss of water flow power, thereby Increase the height of the upwelling, and the upwelling generated by the current flowing through the lower body of the reef can drive the flow of seawater in the upper body cavity of the reef, clean up the sediment in the upper body cavity of the reef, and effectively prevent the clogging of the reef during use.
