Assembly type artificial fish reef with quadrilateral steel structure

Abstract

The invention relates to an assembly type artificial fish reef with quadrilateral steel structure. The artificial fish reef comprises a structure assembly and a function assembly, wherein the structure assembly and the function assembly are detachably connected in an assembled mode; the structure assembly comprises reef body supporting frames, a water permeable support and a bottom supporting plate; the reef body supporting frames, the water permeable support and the bottom supporting plate are made of seawater corrosion resistant steel; the reef body supporting frames are of the three-dimensional frame structure with inner and outer double-quadrangles, a hook is arranged at the top, and the water permeable support is arranged at the bottom; the functional assembly comprises cement corrugated plates with rough surfaces; the cement corrugated plates are assembled between the reef body supporting frames at intervals to form a multi-layer and multi-hole artificial fish reef; and the included angle between the cement corrugated plates assembled between the reef body supporting frames and a horizontal plane ranges from 20 degrees to 45 degrees. According to the artificial fish reef, environment-friendly and low-cost materials are selected, the assembled artificial fish reef that is light in structure and convenient to assemble is prepared, and the artificial fish reef is convenientto produce and use due to standardized component production and assembly.

Description

technical field [0001] The invention relates to the technical field of marine ranching, relates to artificial fish reefs, and in particular to a quadrangular steel structure assembled artificial fish reef. Background technique [0002] With the rapid development of my country's economy and society and the continuous growth of population, affected by many factors such as environmental pollution, engineering construction and overfishing, my country's offshore fishery resources have seriously declined, the ecological environment of waters has deteriorated, and desertification of waters has become increasingly obvious, which has seriously affected my country's marine life. Resource conservation and sustainable use. [0003] Marine ranching is based on the principle of marine ecosystems. In specific sea areas, artificial fish reefs, proliferation and release are used to construct or repair the places needed by marine organisms for reproduction, production, baiting or avoiding enem...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the artificial fish reefs put in place are reinforced concrete structures, which have many shortcomings: first, the reefs are bulky, have high requirements on the bottom quality, and are prone to subsidence and sedimentation; second, the production process is very polluting to the environment. It occupies a large space and has a long prefabrication period; thirdly, the reinforced concrete material does not use the structural design, and the function of the fish reef cannot be maximized; fourthly, due to its high self-weight, it is easy to silt up, and it is difficult to transport and put in, which limits the reinforcement The specifications of concrete reefs generally do not exceed 3 meters in length, width and height, so that the effect is not obvious when placed in relatively deep sea areas
