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

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 and figure 2 As shown, a hydraulically controlled movable deep-water net cage supporting device of the present invention is used to support the deep-water net cage, including a deep-water net cage fixer and a driving device, and the driving device includes a main drive circuit and a backup drive circuit and an overload protection circuit.

[0016] The main driving circuit of the present invention includes a first electric motor 1, a second electric motor 3, a first two-way variable motor 17, a second two-way variable motor 18, a first propeller 19, a second propeller 20, a two-way variable hydraulic pump 2 and a first Two-way quantitative hydraulic pump 4. When the device works normally, the first motor 1 drives the two-way variable hydraulic pump 2, the second motor 3 drives the first two-way quantitative hydraulic pump 4, a...

Abstract

The invention discloses a hydraulic control movable device for supporting deepwater net cages. The device comprises a main drive circuit, a standby drive circuit and an overload protection circuit. The main drive circuit is used for driving the supporting device, the standby drive circuit is used for conducting auxiliary drive when the supporting device needs larger drive force, and the overload protection circuit is used for limiting high-pressure lateral pressure and low-pressure lateral pressure of the main drive circuit. The deepwater net cages are fixed to the portions above the hydraulic control movable device for supporting the deepwater net cages, when wind wave comes, the device provides sailing power for the deepwater net cages and drives the net cages to be hidden in safety zones, and therefore the problem that ordinary floating type deepwater net cages generally cannot resist wind or wave can be effectively solved, and economic losses generated in typhoon and other severe weather are effectively reduced.

Description

technical field [0001] The invention relates to a hydraulically controlled 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 typh...
