Seedling inserting rope-shell combined artificial algal reef

Abstract

The invention provides a seedling inserting rope-shell combined artificial algal reef, comprising a frame type bottom groove which is formed by welding reinforcing steel bars, wherein the bottom groove comprises a bottom surface and four lateral surfaces. A steel plate is welded on the centre of the bottom surface, a vertical rod is welded on the centre of the steel plate, the other end of the vertical rod is welded with a steel ring, the steel ring is connected with the bottom groove through the seedling inserting rope, and a shell net bag is arranged in the bottom groove. The net bag made of waste shells are put into the frame type bottom groove to form a biological closeness reef and realize the resource utilization of the waste shells, so the algal reef has advantages of economic, simple and convenient. The invention adopts the seedling inserting ropes to insert the seaweeds and adopts the rough surfaces and porous structures of the shells and the spaces among the shells to provide a good habitat for microorganism and food organism or provide a best environment for rooting the seaweeds. When a certain number of the seaweeds are bred, a large number of oxygen can be produced, and carbon dioxide in the water can be reduced, so that the water can be purified, and the red tide can be prevented.

Description

technical field [0001] The invention relates to a seedling rope-shell composite artificial algae reef. Background technique [0002] Algae farm is an important part of the marine ecosystem. It can provide a place for various marine organisms to inhabit, spawn, raise young, feed and avoid enemies. It can improve the surrounding flow field environment, reduce seawater nutrient load, inhibit red tide organisms Improving the ocean's carbon sequestration capacity has an important ecological role. However, since the 1980s, my country's coastal natural algae farms have been severely degraded, mainly due to land reclamation, land-based pollution, and unreasonable fishery production. Therefore, the restoration and reconstruction of algae farms is urgent. Since the implementation of China’s Action Plan for the Conservation of Aquatic Biological Resources in 2006, coastal provinces and cities have successively carried out the restoration of offshore fishery resources and the environme...

AI Technical Summary

Problems solved by technology

Since concrete and stones are used as reef building materials, the cost is high, and the period required for the natural growth of algae is long. In order to speed up the recovery of algae fields and provide a good habitat for benthic organisms, it is necessary to provide a shell with simple design and environmental friendliness. biophilic artificial reef
