Wave-powered floating box type coral undersea cultivation device facilitating coral growth

Abstract

The invention discloses a wave-powered floating box type coral undersea cultivation device facilitating the coral growth. The device is composed of a coral cultivation module and a wave energy conversion module; the main body structure of the coral cultivation module is a coral cultivation box; the bottom of the coral cultivation box is provided with a floating body, and the inner portion of the coral cultivation box is horizontally provided with a coral transplantation plate; the wave energy conversion module is connected with the coral cultivation module through a stay chain, and the wave energy conversion module comprises a base, a generator set and a hydraulic cylinder. Under the action of waves, the coral cultivation box oscillates up and down to drive a piston to reciprocate throughthe stay chain, the conversion of wave energy-mechanical energy-electric energy is finally achieved through the generator set, on one hand, the produced electric energy is supplied to a light source in the coral cultivation box to promote photosynthesis of phycobiont on the surfaces of corals, on the other hand, the electric energy is supplied to a graphite electrode to electrolyze seawater to reduce the acidity of the seawater, thereby increasing the calcification rate of the corals and multi-directionally promoting the coral growth. The wave-powered floating box type coral undersea cultivation device facilitating the coral growth has the advantages of being novel in design and friendly to the environment and having very important economic value and ecological significance.

Description

technical field [0001] The invention relates to the field of marine ecological restoration, in particular to a floating box type coral seabed cultivation device powered by waves and beneficial to coral growth. Background technique [0002] The coral reef ecosystem is one of the most biologically diverse ecosystems. It not only provides an ideal habitat for many marine organisms, but also a sufficient source of food and a place to thrive. As a "tropical rainforest in the ocean", coral absorbs a large amount of carbon dioxide in the process of building reefs, which alleviates the global greenhouse effect. At the same time, coral reefs also act as natural breakwaters, attenuating strong waves and currents, protecting coastlines from erosion, and greatly protecting the personal and property safety of the people. The coral reef ecosystem is also a sacred place for people to go sightseeing and scientific research, and it is one of the most precious ecosystems on earth. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] Among the many published technical patents at present, coral seabed cultivation devices are mostly arranged on the seabed. For a long time, sedimentation not only greatly affects the survival rate of transplanted corals, but also has an unpredictable impact on the ecological environment of the sea area where they are arranged.

In addition, due to the limitation of seabed elevation, the photosynthesis of symbiotic algae on the coral surface is inhibited, and the introduction of power supply cannot maintain the power supply for long-term underwater cultivation, which affects the growth of coral transplanted on the seabed

In summary, there are many problems in the past technology that seriously affect the coral restoration process
