A frame upwelling artificial fish reef

technical field

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

Background technique

In recent years, my country's fishery has occupied an important position in the world and has become the world's largest marine fishery country. However, with the modernization and mechanization of fishing boats, as well as the accumulation of fishermen's production experience and the maturity of fishing technology, the natural regeneration of fishery resources has been unable to withstand the increase in fishing intensity, and traditional high-quality resources in coastal and coastal areas of various sea areas have declined one after another. At the same time, with the advancement of industrialization and urbanization in our country, the area rich in offshore fishery resources has become one of the most polluted areas. The environmental quality of sea areas has declined significantly, and the ecological environment is deteriorating day by day, and has harmful effects on biological resources and human health. Marine environmental pollution is a fatal blow to fishery resources and has caused irreversible damage to marine ecosystems.

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. However, the existing artificial fish reefs are still similar in structure, mainly aiming at how to provide places for fishes to breed, grow, bait and shelter enemies. As a result, the thermocline and halocline in the sea area appear, which 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 this utility model is to provide a frame upwelling artificial fish reef, which can provide an environment conducive to the formation of different flow fields such as upwelling, so that the nutrients deposited on the seabed can rise, and the circulation of nutrient salts on the seabed can be promoted. Improve the reproduction and breeding ability of plankton, form an excellent bait field, attract the accumulation and retention of migratory fish, and achieve a better fish gathering effect. At the same time, the upwelling generated by the reef body can drive the seawater flow in the reef body cavity Cleaning up the blockages in the body cavity of the fish reef can effectively prevent the blockage of the fish reef during use, and create favorable conditions for the spawning and reproduction of fish and other aquatic organisms, so as to achieve the goals of protecting, adding value to fishery resources and increasing catches Purpose.

The purpose of this utility model is achieved through the following technical solutions: it is composed of a fish reef body, a support plate and a foot. For supporting the fish reef body, the surface of the support plate is provided with through holes, the feet are fixed on the bottom surface of the support plate, and the frames of the fish reef body are connected by steel bars.

Notable features of the present utility model are:

The fish reef body of a frame upwelling artificial fish reef is a frame structure, and the gaps between the frame structures help the flow of sea currents, drive the flow of sea water in the body cavity of the fish reef, and clean up the blockages in the body cavity of the fish reef, It can effectively prevent the clogging of fish reefs during use, and the frame structure is also conducive to the attachment of fish eggs, providing favorable conditions for the reproduction of fish and other aquatic organisms. Provide a variety of flow field environments, create a good habitat for marine organisms, and achieve better fish gathering effects.

The trapezoidal column on the reef body of a frame upwelling artificial fish reef is conducive to the formation of upwelling, which makes the nutrients deposited on the seabed rise, promotes the exchange between the bottom seawater and the upper water body, and improves the reproductive ability of plankton , form an excellent bait field, and at the same time, the trapezoidal column frame structure of the reef body can increase the flow rate and height of the upwelling, and the formed upwelling can further drive the seawater flow in the reef body cavity, which is conducive to value-added and fishery optimization resources, saving rare and endangered species and protecting biodiversity.

detailed description

Below by embodiment, in conjunction with accompanying drawing, the technical scheme of the utility model is further described:

Referring to Fig. 1, a frame upflow artificial reef provided by the embodiment of the utility model is composed of a reef body 1, a support plate 2 and a foot 3, and the reef body 1 is composed of two horizontal A frame structure composed of trapezoidal column layers interlaced and stacked. The support plate 2 is used to support the fish reef body 1. The surface of the support plate 2 is provided with a through hole 21. The foot 3 is fixed on the bottom surface of the support plate 2. The frames of the fish reef body 1 are connected by steel bars.

Referring to Figure 1, when the seabed current flows through the frame structure of the reef body, the gaps between the frame structures help the flow of the sea current, drive the flow of seawater in the cavity of the reef body, and clean up the blockage in the cavity of the reef body. It can effectively prevent the clogging of the reef during use, and at the same time form a back vortex on the side and back of the reef body, provide various flow field environments for different fish, create a good habitat for marine organisms, and achieve a better fish gathering effect .

See Figure 1. When the seabed water flows through the trapezoidal column of the fish reef body, an ascending current will be formed. The layered trapezoidal column frame structure of the fish reef body will enhance the flow velocity and flow of the upwelling, and the water flow will rise along the side of the trapezoidal column. It can effectively reduce the flow power, help to increase the height of the upwelling, make the nutrients deposited on the seabed rise, promote the exchange between the bottom seawater and the upper water body, enhance the reproduction and breeding ability of plankton, and form an excellent bait field. The current can drive the flow of seawater in the body cavity of the reef, improve the ecological environment of the reef sea area, and increase the primary productivity of the sea area near the artificial reef.

See Figure 1. The interior of the reef body is hollowed out, and there are gaps on the side. Young fish can enter the inner cavity of the reef through the gap, gather, grow and avoid enemies in the inner cavity of the reef. At the same time, the frame structure is also conducive to the attachment of fish eggs. The reproduction of fish and other aquatic organisms provides favorable conditions to achieve the purpose of protection, value-added fishery resources and increased catch.

Referring to Figure 2, there is a through hole on the support plate of the artificial reef. When the artificial reef is placed, the through hole is conducive to the flow of water and can increase the stability of the artificial reef. At the same time, the sediment in the reef body can pass through. The through-hole settles on the seabed, which is beneficial to clear the blockage in the body cavity of the reef, and can effectively prevent the clogging of the reef during use.
