A hollow cylinder type seabed coral cultivation device and method

Abstract

The invention discloses a hollow cylindrical seabed coral cultivation device and method, which are used for transplanting corals to the seabed. The top of the device is sealed with a cylinder top cover plate with openings, and a number of evenly arranged and uniformly sized installation holes are arranged on the side wall of the cylinder. The transplanted coral attachment base is in the shape of a horizontal cylinder, and the tail is equipped with a press-in fastening nail, so as to achieve efficient and stable fixation with the installation hole. There are vertical pressure piles at the bottom of the device. The cylindrical structure of the device of the present invention has the characteristics of the force of the arched structure, and the bending moment is small under the complex dynamic conditions of the ocean, so it is not easy to overturn. The device of the invention innovatively adopts the technology of transplanting corals inside the cylinder, which can not only resist harsh conditions such as strong wind and waves, but also effectively avoid the threat of natural enemies. The invention can be integrally prefabricated with transparent PC materials, utilizes light with maximum efficiency, promotes the photosynthesis of coral symbiotic algae, improves the growth ability of transplanted corals, and has a small underwater floating weight, reducing the workload of divers for arrangement and placement.

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
