Description

A spiral upwelling artificial fish reef

technical field

The invention relates to the technical field of fish reefs, in particular to a spiral upflow artificial fish reef.

Background technique

With the development of the society, the population is growing day by day, the living standard is constantly improving, and people's demand for marine life, especially fish, is constantly increasing. The high-intensity operation of trawl nets and other destructive fishing gear has seriously damaged the marine environment and fishery resources. The intensity of marine fishing is too high, fishery resources continue to decline, fishery production continues to decline, and marine habitats are degraded and lost. The trawling fishery causes structural changes in the habitat of marine low-dwelling organisms, reduces the population and species of marine organisms, and deteriorates the resource structure. The introduction of artificial reefs has played a very important role in restoring and protecting offshore fishery resources and improving the coastal ecological environment, which makes artificial reefs be valued and applied.

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 object of the present invention is to provide a spiral upwelling type 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 provide a kind of effective It is conducive to the formation of different flow field environments such as upwelling, which makes the nutrients deposited on the seabed rise, promotes the cycle of nutrient salts on the seabed, enhances the reproduction and breeding ability of plankton, forms an excellent bait field, and attracts the gathering and gathering of migratory fish. Detention to achieve better fish gathering effect. At the same time, it can also use the upflow generated by the conical block to drive the seawater flow in the reef body cavity, clean up the blockage in the reef body cavity, and provide for the survival and reproduction of fish and other aquatic organisms. Create favorable conditions to achieve the purpose of protecting, adding value to fishery resources and increasing catches.

The purpose of the present invention is achieved through the following technical solutions: it is composed of a fish reef body, a tapered block, a support column and a base. The fish reef body is a prism structure with a spiral curved surface on the side. A through hole is provided, the conical block is a conical body structure fixed on the base, the top of the conical block is opposite to the through hole at the bottom of the reef body, and the support column is fixed on the base to support the reef body.

Salient feature of the present invention is:

The side of the fish reef body of a spiral upwelling artificial fish reef is a spiral curved surface. When the sea current flows through the fish reef body, it can effectively use the sea current to form an upwelling. Among them, the spiral curved surface of the fish reef body can effectively reduce the loss of water flow power, play the role of water flow upward diversion, reduce the water flow to the horizontal flow on both sides of the reef, thereby increasing the flow and height of the upwelling, so that the sediment on the seabed Nutrients rise, driving the bottom layer of nutrients to exchange with the upper water body, providing nutrients for the reproduction and growth of plankton in the upper water body, creating a good habitat for marine organisms, and achieving a better fish gathering effect. A large-scale back vortex is formed on the back and back, providing various flow field environments for different fish.

The conical block of a spiral upwelling artificial fish reef is a conical structure whose top is opposite to the through hole at the bottom of the reef body. The flow of seawater in the cavity creates a good habitat for fish and other aquatic organisms. At the same time, it can also clean up the sediment in the cavity of the reef body, which can effectively prevent the clogging of the reef during use.

detailed description

Below by embodiment, technical solution of the present invention is described further in conjunction with accompanying drawing:

Referring to Fig. 1, a spiral upflow artificial fish reef provided by the embodiment of the present invention is composed of a fish reef body 1, a conical block 2, a support column 3 and a base 4, and the fish reef body 1 is a side surface It is a prismatic structure with a spiral curved surface. Each surface of the fish reef body 1 is provided with a through hole 11. The conical block 2 is a conical structure fixed on the base 4. The top of the conical block 2 faces the fish. There is a through hole 11 at the bottom of the reef body 1 , and the support column 3 is fixed on the base 4 for supporting the reef body 1 .

Referring to Fig. 1, when the seabed current hits the spiral surface of the fish reef body, the spiral surface can effectively use the ocean current to form an upwelling, and in the process of the water flow upwards along the outer side of the fish reef body, the spiral surface of the fish reef body can be Effectively reduce the loss of water flow power, play the role of water flow upward diversion, reduce the water flow to the horizontal flow on both sides of the reef, thereby increasing the flow and height of the upwelling, so that the nutrients deposited on the seabed rise, driving the bottom nutrients Materials are exchanged with the upper water body, providing nutrients for the reproduction and growth of plankton in the upper water body, creating a good habitat for marine organisms, and achieving a better fish gathering effect. At the same time, a large-scale back vortex is formed on the side and back of the reef body, Provide various flow field environments for different fish, improve the ecological environment of the fish reef sea area, and increase the primary productivity of the sea area near the artificial fish reef.

See Figure 1. There are through holes on the outer surface of the fish reef body. Fish and other aquatic organisms can enter the inner cavity through the through holes, gather, grow and avoid enemies in the inner cavity. At the same time, the water flow in the inner cavity is relatively gentle, which is conducive to Organisms lay eggs and reproduce here to achieve the purpose of protecting, adding value to fishery resources and increasing catches.

Referring to Fig. 2 and Fig. 3, when the seabed current hits the side of the conical block, it helps the formation of the upwelling, and the formed upwelling can drive the seawater in the cavity of the reef body to flow through the through hole at the bottom of the reef body. Such aquatic organisms can create a good habitat, and at the same time, it can also clean up the sediment in the body cavity of the reef, which can effectively prevent the clogging of the reef during use.
