Transparent cylindrical undersea coral cultivation device and method

Abstract

The invention discloses a transparent cylindrical undersea coral cultivation device and method, and is used for transplanted coral seabed cultivation. A sealing frame on the top of the device is provided with a cylinder top cover plate with holes, and multiple mounting holes with uniform distribution and same size are formed in the side wall of a cylinder. A transplanted coral adhesion medium is in a transverse cylinder shape, and the tail of the transplanted coral adhesion medium is provided with a press-in type fastening nail, thereby achieving efficient and stable fixation with the mounting holes. The bottom of the device is provided with a vertical pressure-bearing pile. The cylinder structure of the device has the stress characteristic of the arch structure, the bending moment is smaller in the marine complex power condition, and overturning does not occur easily. The device innovatively adopts a coral transplanting technology in the cylinder, which not only can resist strong wind and waves and other harsh conditions, but also can effectively avoid the threat of natural enemies. The device can be integrally prefabricated by adopting a transparent PC material, the illumination is utilized to the maximum extent to promote the photosynthesis of coral phycobiont and improve the growth capacity of the transplanted corals, the underwater buoyant weight is smaller, and the workload of the arrangement and placement by a diver is reduced.

Description

technical field [0001] The invention relates to the field of marine ecological restoration, in particular to a hollow cylinder type submarine coral cultivation device and method. Background technique [0002] The coral reef ecosystem plays an important role in the marine ecosystem and has always been the source of the evolution of countless marine organisms. On the one hand, it can play a pivotal role in marine disaster reduction, and on the other hand, it can maintain the integrity of the ecosystem. For more than two hundred years since the Industrial Revolution, corals, which are extremely sensitive to the marine environment, have faced various deadly threats such as pollution, overfishing, and bleaching. The global coral coverage and species diversity have declined sharply. It is on the verge of extinction by the end of this century, and it is urgent for human beings to take action to protect and rebuild. [0003] In recent years, many organizations at home and abroad ha...

Problems solved by technology

[0004] Among the many published technical patents at present, the structure is complex and the stability is poor, the submarine construction is difficult, the workload of divers launching is heavy, the economic investment is too high and the efficiency is low

Not only that, the existing cultivation device technology makes the transplanted corals almost exposed and vulnerable on the seabed, whether it is the damage from strong winds and waves, or the invasion of various natural enemies, it will cause huge irreparable losses. Efforts have been wasted, so new technologies are urgently needed to realize multi-faceted ecological, structural and economic aspects to ensure the survival rate and growth rate of seabed cultured and transplanted corals, and to accelerate the restoration of marine ecology
