Intelligent new energy floating offshore pipeline truss connection type far reaching sea culture integrated body

Abstract

The invention discloses an intelligent new energy floating offshore pipeline truss connection type far reaching sea culture integrated body. The intelligent new energy floating offshore pipeline trussconnection type far reaching sea culture integrated body comprises culture net cages, a floating central service platform, a transport ship and a floating offshore pipeline truss; the several culturenet cages are arranged to surround the floating central service platform; a lower buoyancy structure of the floating central service platform is formed by modular stacking of a main buoyancy module;an upper platform structure provides a storage space for platform workload; the net cage framework of the culture net cage is a space truss structure; the difficulties of wind and wave resistance andbenefit offering are solved; the manufacturing and construction difficulty is low; the construction period is short; the transport ship travels between the continental rise and the floating central service platform to transport feeds, energy and equipment; the floating central service platform and the various culture net cages are connected through the floating offshore pipeline truss respectively; platform feeding equipment is arranged on the floating central service platform; and the platform feeding equipment is connected with net cage feeding equipment on the culture net cage needing to befed, so that the feed is fed into the a culture water body space.

Description

technical field [0001] The invention belongs to the field of marine engineering devices, especially deep-sea aquaculture equipment, and specifically relates to an intelligent new energy floating offshore pipeline truss-connected deep-sea aquaculture complex. Background technique [0002] Compared with international aquaculture technology, my country's near-shore marine aquaculture technology is relatively mature, mainly based on family-style and small-scale production methods, and has not formed a scale effect. It is difficult to support the large-scale production method of deep-sea aquaculture, and it is really involved in deep-sea aquaculture. Almost no experience. In addition to lagging behind other advanced countries in terms of fishing boats and breeding equipment, deep sea farming also faces more complex natural sea conditions. [0003] The natural geographical environment has become a major objective factor affecting deep-sea aquaculture. my country's coastal sea con...

AI Technical Summary

Problems solved by technology

[0016] The deformation of deep-water cages due to ocean currents cannot be ignored. In the case of ordinary gravity-type cages with a water flow of 1 m / s, the volume loss rate of the cages can be as high as 80%, which greatly compresses the aquaculture water body and is not conducive to fish growth.

[0017] Net cleaning and replacement mainly rely on manual operation, the underwater operation is difficult, and the anti-fouling technical requirements are high

[0018] The stress response of fish in aquaculture is also prominent. The environment of deep-sea aquaculture is more complex, with many and uncertain factors such as wind, air pressure, water flow, temperature, light, and salinity. It is a natural action to overcome the stress response, and lacks the technical means and ability to adapt and adjust to the environment. Therefore, the stress response of fish is more serious and uncontrollable, resulting in slow growth and development of fish, decreased reproductive ability, and low immune function. resulting in increased morbidity and even sudden death

[0019] Another example is the net cage of CN109874716A, although there are suspension cables and snorkeling functions, they all carry out vertical snorkeling with the net cage as a whole. Usually it is necessary to catch fish by collecting the net, but it has to rely on external ship machinery, and the cage and the net body need to be separated first, which is prone to entanglement and incomplete separation, and the machine will tear the net and cause a large loss of fish. , the mechanical net needs to be cautious, which is very time-consuming and inefficient (this is also the case when the net is cleaned and replaced)

This problem becomes more prominent when the unpredictable wind and waves and other harsh external environments come. It is a big problem for ships to sail. Even if they sail, the window period is too late to complete fish collection or transfer. The strength is not enough, and the ability to avoid risks is also insufficient. Therefore, accidents often occur in the suspension net cages after the storm, causing huge economic losses.
