Large-seaweed anti-wind wave cultivation apparatus used for adsorbing and purifying arsenic in seawater

Abstract

The invention discloses large-seaweed anti-wind wave cultivation apparatus used for adsorbing and purifying arsenic in seawater. The apparatus comprises a floating frame, a sunk frame arranged below the floating frame, floating balls and counterweight blocks, the floating balls are connected with the floating frame through ropes, the counterweight blocks are connected with the sunk frame through ropes, a plurality of supporting rods are fixed between the floating frame and the sunk frame at intervals, the floating frame, a shaping frame and the supporting rods form a cultivation framework, a plurality of upper-lower symmetrical hanging ropes are separately arranged in the floating frame and the sunk frame at intervals, seedling ropes are fixed between upper hanging ropes and lower hangingropes, seedling clamps are arranged on the seedling ropes along a longitudinal direction at intervals, hollow cavities communicating with each other are arranged in the floating frame, the hollow cavities form a buoyancy regulating cavity, the bottom surface of the floating frame is provided with a one-way drainage pipe which communicates with the buoyancy regulating cavity, and the floating frameis provided with a buoyancy control device for controlling floating and sinking of the floating frame. According to the invention, the seawater or air is introduced into the buoyancy regulating cavity in the floating frame through the buoyancy control device to control the sinking and the floating of the floating frame, so that the wind wave resisting capacity is improved, the protection of the cultivation framework is realized, and the stable growth and propagation of large seaweed are facilitated.

Description

technical field [0001] The invention relates to the technical field of seaweed cultivation, in particular to a large seaweed anti-storm cultivation device for absorbing and purifying arsenic in seawater. Background technique [0002] With the development of the metal mining industry, a large amount of heavy metals such as arsenic, lead, zinc, cadmium, and copper are discharged into seawater. Once heavy metals are absorbed into the food chain, they will eventually accumulate in organisms and eventually endanger human health. Heavy metal pollution in the marine environment, especially in coastal waters, has become a problem that human beings must face all over the world. The large seaweeds (such as kelp, sargassum, etc.) that are common in the coast of my country have the ability to absorb arsenic, zinc, and cadmium because of their long body and fast growth. At the same time, they can purify harmful substances such as ammonia nitrogen, nitrite nitrogen, and phosphate in seawa...

AI Technical Summary

Problems solved by technology

There are many floats on the seaweed cultivation raft frame, which has huge resistance in wind and waves, resulting in poor wind and wave resistance. When the sea surface is stormy, the main rope shakes violently, and it is easy to pull and shake the hanging rope, causing the large seaweed on the seedling net to break or fall off. Conducive to the normal reproduction and growth of macroalgae
