Self-propulsion type wind and wave resistant deepwater net cage

Abstract

The invention discloses a self-propulsion type wind and wave resistant deepwater net cage. The self-propulsion type wind and wave resistant deepwater net cage comprises a frame, a net and a fixing mooring component used for fixing the net cage in water. The net is fixed to the frame, the net is stretched with the open of the frame, the fixing mooring component and the frame are connected, in addition, the self-propulsion type wind and wave resistant deepwater net cage further comprises a hydraulic propelling device, the hydraulic propelling device is composed of a propeller thruster, a hydraulic motor, a hydraulic circuit, a hydraulic pump and a driving motor, wherein the driving motor and the hydraulic pump are connected and drive the hydraulic pump to work, the hydraulic pump is connected with the hydraulic motor through the hydraulic circuit and drives the hydraulic motor to revolve, and the hydraulic motor and the propeller thruster are connected and reversedly drive the propeller thruster to rotate. The net cage has the advantages that the structure is simple, conducting offshore pilling operation in advance is not needed, the net cage can navigate and move in the water of itself, dragging by a tugboat is not needed, and an excellent wind and wave resistant ability is possessed.

Description

Technical field [0001] The invention relates to a deep-water net cage applied to the deep-water aquaculture industry, and more specifically, to a self-propelled anti-wind and wave deep-water net cage. Background technique [0002] With the rapid development of deep-water cage aquaculture, deep-water cage aquaculture has produced significant social and economic benefits. Modern cages are mainly composed of nets, frames and fixtures. The cages are positioned on the seabed by the fixtures. Deep-water cages are generally fixed by surrounding piles. The piles are first connected to the pontoons through the fixing points and then connected to the cage frame by connecting ropes. To ensure that the fixed piles are balanced in force. However, this deep-water cage aquaculture industry has the following disadvantages: [0003] First of all, with the continuous development of the industry, the total production scale continues to expand. Due to the limited water space in the inner bay and ins...

AI Technical Summary

Problems solved by technology

[0003] First of all, with the continuous development of the industry and the continuous expansion of the total production scale, due to the limited space in the inner bay waters and insufficient water exchange, the density of cage culture continues to increase, resulting in excessive local density, which damages the environment and causes frequent diseases. A series of problems such as lower quality, higher operating costs, and increased risks

[0004] Secondly, the construction procedures of offshore piling operations are complex, demanding and costly;

[0005] Thirdly, the ability to resist wind and waves is poor. If encountering natural disasters such as typhoons, it is easy to cause the death of farmed organisms in batches and bring economic losses to fishermen;

[0006] Finally, due to the high breeding density of cage culture, when an outbreak occurs in the cultured organisms, the traditional cage cannot be moved, and the epidemic is easy to spread, causing a large-scale epidemic and causing economic losses to fishermen
