A pontoon-type coral seabed cultivation device beneficial to coral growth powered by waves

Abstract

The invention discloses a floating box-type coral seabed cultivation device powered by waves and beneficial to coral growth, which is composed of a coral cultivation module and a wave energy conversion module; the main structure of the coral cultivation module is a coral cultivation box; the bottom is provided with a floating body for coral cultivation A coral transplantation board is arranged horizontally inside the box; the wave energy conversion module is connected with the coral cultivation module through a tether, and the wave energy conversion module includes a base, a generator set and a hydraulic cylinder. Under the action of waves, the coral incubator oscillates up and down through the tether to drive the piston to reciprocate, and finally realizes the conversion of wave energy-mechanical energy-electric energy through the generator set. On the one hand, the generated electric energy supplies the internal light source of the coral incubator to promote the photosynthesis of symbiotic algae on the coral surface. On the one hand, it supplies graphite electrodes to electrolyze seawater to reduce the acidity of seawater, increase the rate of coral calcification, and promote coral growth in multiple directions. The invention is novel in design, friendly to the environment, and has 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
