A submarine coral cultivation device using tidal current energy to generate electricity

Abstract

The invention discloses a seabed coral cultivation device using tidal current energy to generate electricity, which is composed of a coral cultivation module, a tidal current energy conversion module and a horizontal load-bearing pile. The main structure of the coral cultivation module is composed of coral cultivation racks, light sources, and coral attachment bases; the tidal current energy conversion module includes blades, generator sets and yaw systems. Under the action of the reciprocating tidal current, the yaw system drives the blades towards the direction of the incoming flow, and the generator set realizes the conversion of tidal current energy to mechanical energy and then to electrical energy, which supplies power to the light source and promotes the photosynthesis of symbiotic algae on the surface of coral reefs and increases the growth rate of corals. At the same time, the rotation of the blade dissipates the energy of the single-width incoming flow, which improves the survival rate of transplanted corals under strong ocean dynamic conditions. The invention utilizes tidal current energy to generate electricity to promote and protect seabed transplanted coral cultivation, which is creative, novel and sustainable, and has significant practical value and ecological significance.

Description

technical field [0001] The invention relates to the field of marine ecological restoration, in particular to a seabed coral cultivation device using tidal current energy to generate electricity. Background technique [0002] Coral reef ecosystem, as a tropical rainforest in the ocean, is one of the most biologically diverse ecosystems on earth and one of the oldest ecosystems. It not only contains rich oil and gas resources, fishery resources, but also unique and valuable Marine tourism resources. At the same time, the coral reef ecosystem can resist strong ocean dynamics and buffer the damage and economic losses caused by storm surges to coastal cities. However, in recent decades, due to the acceleration of human industrial processes and the global warming environment, human activities have caused the coral reef ecosystem to face unprecedented threats. In the next 20 to 30 years, coral reefs in many areas may endangered. Experts and scholars at home and abroad have paid ...

AI Technical Summary

Problems solved by technology

At the same time, due to the limitation of seabed elevation, the photosynthesis of symbiotic algae on the coral surface is inhibited, and it is difficult to introduce long-term power supply for coral cultivation devices arranged in the far sea and deep sea. Sea-floor transplanted coral grows slowly

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