Artificial fish reef with impeller shafts

Abstract

The invention relates to an artificial fish reef with impeller shafts. The artificial fish reef with the impeller shafts is formed by a base, the impeller shafts, side plates and a top cover, can provide a place for breeding, growing and feeding fishes, meanwhile can effectively produce an upwelling, drives substances such as bottom nutritive salt to exchange with an upper water body, improves the ecological environment in a fish reef sea area, and provides sufficient baits for growing and breeding the fishes. At the same time, the rotation of the impeller shaft can also drive ventilation in the fish reef, and can effectively prevents the blockage of the fish reef during the application process; deflectors arranged on the side plates of the fish reef can also effectively guide an ocean current to flow upwards after passing through the fish reef so as to produce the upwelling, so that the primary productivity in adjacent sea areas of the fish reef is greatly improved.

Description

[0001] The invention relates to an artificial fish reef, in particular to an artificial fish reef with an impeller shaft. Background technique [0002] In recent years, although the development of my country's fishery has advanced by leaps and bounds, the traditional marine fishery is still in the extensive stage, with a small scale and relatively low output value. With the rapid development of the fishery, the problems exposed by the fishing industry in the fishery are also increasing. Many, my country's marine environment and fishery resources have been severely damaged under the pressure of continuous high-intensity fishing. In view of the above problems, it is imperative to take measures to improve the marine environment and resources. Among them, artificial fish are placed in the offshore The artificial reefs have achieved good results in improving the marine ecological environment, and the deployment of artificial reefs has played a very important role in restoring and prot...

Problems solved by technology

[0002] In recent years, although the development of my country's fishery has advanced by leaps and bounds, the traditional marine fishery is still in the extensive stage, with a small scale and relatively low output value. With the rapid development of the fishery, the problems exposed by the fishing industry in the fishery are also increasing. Many, my country's marine environment and fishery resources have been severely damaged under the pressure of continuous high-intensity fishing. In view of the above problems, it is imperative to take measures to improve the marine environment and resources. Among them, artificial fish are placed in the offshore The improvement of the marine ecological environment has achieved good results, and the introduction of artificial reefs has played a very important role in restoring and protecting offshore fishery resources and improving the coastal ecological environment.

[0003] 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. Therefore, 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 ginseng and plankton. Therefore, how to improve the upwelling effect of artificial reefs It is a difficult point in artificial reef structure design and technology
