A movable support device for deep water net cage

Abstract

The invention discloses a movable supporting device for a deepwater net cage. The movable supporting device is used for supporting the deepwater net cage and comprises deepwater net cage fixing apparatuses and a supporting table. A driving device is mounted in the supporting table and comprises a driving system, a shafting system and a propulsion system. The driving system comprises a main unit and a gear box; the shafting system comprises a thrust shaft, a thrust shaft bearing, a first connecting shaft flange, an intermediate shaft, an intermediate bearing, a second connecting shaft flange and a screw shaft pipe; the propulsion system comprises a propeller. The movable supporting device has the advantages that the deepwater net cage can be fixed to the upper side of the supporting table by the aid of the deepwater net cage fixing apparatuses, sailing power can be provided by the movable supporting device for the deepwater net cage before wind waves arrive, the net cage can be driven to evade in a safety zone, accordingly, the problem that common floating deepwater net cages are generally not wind-resistant and wave-resistant can be effectively solved, and economic loss in severe weather such as typhoon can be effectively reduced.

Description

technical field [0001] The invention relates to a movable deep-water net cage supporting device, which belongs to the technical field of deep-water net cages. Background technique [0002] In recent years, typhoons have been fatal to the destruction of deep-water cages. Taking Taizhou City, Zhejiang Province as an example, since the beginning of summer in 2013, there have been many typhoons that have affected Taizhou City, among which Typhoon No. 23 "Fitte" has had the greatest impact. According to statistics, typhoon "Fite" caused a total direct economic loss of 476 million yuan in the city's fishery industry, of which: 56,500 mu of aquaculture area was damaged, and the output loss was 8,600 tons. caused great economic losses. The current deep-water cages generally adopt a floating structure, and anchoring technology is used to fix the cages. The structure is simple, and it does not have the mobility of ships and other marine vehicles. When a typhoon comes, it cannot esca...

AI Technical Summary

Problems solved by technology

caused great economic losses

The current deep-water cages generally adopt a floating structure, and anchoring technology is used to fix the cages. The structure is simple, and it does not have the mobility of ships and other marine vehicles. When a typhoon comes, it cannot escape to a safe area in time, so it is generally not resistant The ability to resist wind and waves often suffers huge losses when bad sea conditions come
