Steel structure artificial reef

Abstract

The invention discloses an artificial fish reef in a steel-frame structure and aims to overcome the defects that an existing artificial fish reef is single in shape and function and low in economical benefit, is easy to block if being used in sea for a period of time, is adverse to gathered life of a fish school, and the artificial fish reef under the sea is relatively poor in stability and easy to swing to affect life of the fish school. The artificial fish reef in the steel-frame structure disclosed by the invention comprises an algae culture matrix and a fish reef matrix, wherein the lower end of the fish reef matrix is fixedly connected with a steel rack and the algae culture matrix is connected with an impact ball for impacting the fish reef matrix; high pressure gas for flushing a fish sheltering cavity is arranged on the fish reef matrix; the impact ball triggers a resilient mechanism to cut a gas cover, so that high pressure gas escapes to flush the fish sheltering cavity so as to prevent the fish sheltering cavity from being blocked. The artificial fish reef not only can provide a place for the fish school to inhabit, reproduce and shelter enemies, but also can be used for cultivating algae, so that the artificial fish reef is high in economical benefit. The artificial fish reef put in use is good in stability, and the fish sheltering cavity in the fish reef matrix is hardly blocked.

Description

technical field [0001] The present invention relates to an artificial fish reef, more specifically, it relates to a steel frame structure artificial fish reef. Background technique [0002] Artificial fish reefs are structures artificially set up in the sea. The purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, feed and shelter enemies, so as to achieve protection, multiplication and The purpose of increasing catches. At present, the construction of artificial reefs has been extensively carried out at home and abroad, and the restoration of offshore marine biological habitats and fishing grounds has achieved certain results. However, many artificial reefs currently in use have single shapes and functions, and low economic benefits. After being used in the sea for a period of time, it is prone to blockage, which is not conducive to the gathering and livi...

Problems solved by technology

[0004] The present invention overcomes the single shape and function of the existing artificial fish reef, low economic benefits, the phenomenon that the artificial fish reef is prone to blockage after being used in the sea for a period of time, which is not conducive to the gathering and life of fish schools, and the stability of the artificial fish reef on the seabed Poor, prone to sloshing phenomenon, affecting the life of fish schools, a steel frame structure artificial fish reef is provided, which has various shapes and functions, not only can gather fish schools, but also can be used to cultivate seaweed, with high economic benefits , the artificial reef is not easy to be blocked during use, which is conducive to the gathering and living of fish schools, and the artificial reef is stable on the seabed, and it is not easy to shake, which ensures the normal life of fish schools
