Modularized semi-submersible type sea fish breeding platform

Abstract

The invention relates to a modularized semi-submersible type sea fish breeding platform. The platform comprises a main platform body structure, net wheels, nets, rotary mechanisms and driving mechanisms, the main platform body structure is internally provided with several parallel rotary mechanisms, and the rotary mechanisms comprise the driving mechanisms, the net wheels and rotary shafts; one net is fixed between every two net wheels, the nets are hung at the two side ends of the adjacent net wheels, and the net wheels of modularized rotary units are supported in the center of the main platform body structure through the rotary shafts; the net wheels are connected with the driving mechanisms to form the independent modularized rotary units, connecting pairs between the driving mechanismsand the net wheels adopt a gear-rack mode or an extruding friction mode, and the nets are driven by the net wheels to rotate. The platform has the advantages that net boxes and the nets automaticallyrotate for net drying to effectively avoid that attachments on the nets grow, and it is ensured that sea water inside and outside the net boxes normally flow circularly. The steps of net replacementand net cleaning can be omitted, and the workload and work intensity of fishermen can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a modularized semi-submersible marine fish farming platform. Background technique [0002] The marine fish breeding platform is a comprehensive fishery production platform with the main function of breeding marine fish. It is set up in offshore and deep waters, and includes auxiliary functions such as turnover of fishing catches at sea, storage and delivery of breeding bait, and supply of fishing boat materials. Therefore, the breeding platform Technology involves multiple disciplines and fields. [0003] The nets of the cages on the breeding platform are easily attached by various marine animals and plants such as algae in the sea in the seawater environment, which increases the weight of the cages, increases the force on the nets, and reduces the service life of the nets. With the accumulation of time, too many attachments will block the mesh of the net clothing, and it...

AI Technical Summary

Problems solved by technology

[0003] The nets of the cages on the breeding platform are easily attached by various marine animals and plants such as algae in the sea in the seawater environment, which increases the weight of the cages, increases the force on the nets, and reduces the service life of the nets.

With the accumulation of time, too much attachment will block the mesh of the net, and at the same time it is difficult to remove

On the one hand, the blockage of the mesh affects the water quality exchange in the cage, resulting in a poor breeding environment in the cage, which seriously affects the healthy growth of marine fish; increase, the entire platform structure will fail under strong wind and wave conditions

At present, the effective way to solve this problem is to change the nets regularly, or to clean the net attachments by artificial diving. very big

[0004] At the same time, the traditional marine fish breeding cages are either fixed on the seabed or close to the coastline, and the breeding space is severely limited. Therefore, it is necessary to expand the breeding cages to the deep sea

However, in deep sea areas, especially in some typhoon-prone areas, the wind and waves are strong, and the impact of wind and waves on cage culture is particularly obvious. The cages are easily damaged or washed away by wind and waves, causing irreparable economic losses.
