An upwelling artificial fish reef

Abstract

The invention relates to a rising streaming artificial fish reef. The rising streaming artificial fish reef is composed of a cube frame, right triangle plates and isosceles triangle plates, the inner side of each upright post of the cube frame is provided with a right triangle plate, the upper edges of four groups of the right triangle plates with a same specification are connected in a cross shape at the top surface center of the cube frame, the inner side of each bottom edge of the cube frame is provided with an isosceles triangle plate, point angles of four groups of the isosceles triangle plate with a same specification are intersected at the top surface center of the cube frame to form a rectangular pyramid structure, each side of the rectangular pyramid is connected with the hypotenuse of the right triangle plate at the inner side of each upright post of the cube frame, and open pores are formed in the right triangle plates and the isosceles triangle plates. The rising streaming artificial fish reef has the advantages of rising streaming effect and remarkable stability performance.

Description

technical field [0001] The invention relates to an artificial fish reef, in particular to a fish reef structure which is more likely to form upwelling. Background technique [0002] Artificial reefs are artificial facilities that improve the ecological environment of sea areas and create habitats for marine organisms. Placing artificial reefs in natural waters can change the original flow field distribution in the sea area and form a flow field structure dominated by "upwelling" and "back vortex". The change of ocean currents in the original sea area can drive the exchange of bottom nutrient salts with the upper water body, provide nutrients for the reproduction of plankton in the surface water body, improve the primary productivity of the sea area, and provide bait for larvae, juvenile fish, shrimp, crab and shellfish, etc. Organisms, and then form the artificial reef fishery, and this is also one of the main factors for the realization of the principle of artificial reef ...

AI Technical Summary

Problems solved by technology

Although these forms of artificial fish reefs have enough surface area to attract algae to attach and gather marine treasures such as sea cucumbers and abalones, their flow field effects are not significant

However, the current concrete component reefs are mostly frame structures, and the upwelling generated is relatively weak, and it is difficult to have a significant effect on the water exchange between the upper and lower aquifers.

[0003] Taking stone reefs as an example, most of them are stacked and grouped, and they are arranged in multiple layers from outside to inside. Although they provide a good habitat for sea cucumbers, on the other hand, they have a blocking effect on ocean currents, especially Under the high temperature, rainy and less windy weather conditions in summer, thermoclines and haloclines appear in sea areas, and the vertical circulation of water bodies is blocked, resulting in the formation of anoxic layer on the seabed, which easily leads to the death of sea cucumbers in large areas
