Problems solved by technology

Compared with the existing submersible cages, the present invention solves the following technical problems: 1. Realize the synchronization of the submersion or floating of the mariculture cages, avoiding the overturning and destruction of the cages caused by the out-of-synchronization of water injection or inflation ;2. Cancel the foam float to avoid white pollution; 3. Reduce the use of water filling (inflating) and other equipment to reduce production costs

specific Embodiment approach

[0033] The concrete implementation that submersible net cage of the present invention enters offshore installation is:

[0034] First complete the foundation installation in the predetermined sea area, and tie the red floating ball on the foundation lug to the water surface. The outer frame 1 of the submersible net cage with the water surface operation platform is connected with the anchor rope 10 before launching, and the outer frame 1 is tied with the salvage operation buoy, then hoisted into the water, positioned and fastened by the auxiliary operation ship , the salvage operation buoy water injection drags the inner frame 2 to sink to the design elevation, and the diver will connect the inner frame 2 with the stay rope 3 by the tension cable of predetermined length and the anti-off safety cable, hang the jacket 4, the counterweight. Afterwards, the diver removes the binding of the casing and the salvage operation buoy, the salvage operation buoy drains and floats away, and...

Abstract

A submerged net cage structurally comprises an outer frame system, an inner frame, net and counterweight system, a lifting system and a mooring system. The outer frame system comprises an outer frame (1), and the inner frame, net and counterweight system comprises an inner frame (2), netting (4) and a counterweight. The lifting system comprises a transmission device, a sliding wheel system and a control device. The outer frame system can serve as the foundation of the inner frame, net and counterweight system due to weight of the netting and the counterweight, and the inner frame, net and counterweight system is controlled by the lifting system to float in water. The mooring system comprises anchor ropes (10) and anchors (11), and the mooring system is connected with the outer frame (1) through the anchor ropes (10). The submerged net cage can easily ascend and descend, synchronization of floating and submergence is good through a mechanical device, and cost is low.

Description

technical field [0001] The invention relates to a submersible net cage used for deep sea culture, which belongs to the field of marine engineering utilization. Background technique [0002] Due to problems such as overfishing and environmental pollution, the decline of fishery resources worldwide has become a serious global problem. The focus of the world's fishery production has shifted from the traditional hunting fishery to the animal husbandry fishery, and the development of sea cage culture of high economic value fish has become the consensus of all countries in the world. Traditional net cages (floating raft net cages) are the main type of net cage facilities, but the wind resistance of this culture structure is poor, so we have to choose the calm waters of the inner bay as a breeding place. Over the years, the over-exploitation of certain inner bays and the weak water exchange capacity of inner bays have led to more and more frequent occurrence of diseases, seriously...
