Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing lifting net cage can only avoid wind and waves by lowering it below the sea surface, and the anti-wave method is single and the net cage cannot be effectively supervised. , when encountering wind and waves, the wave resistance of the cage can be improved by adjusting the size of the floating ring

Embodiment Construction

[0018] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0019] Such as Figure 1 to Figure 5 Shown, a kind of lifting type net cage that can adjust the size of the floating ring includes the floating ring 1 and the bottom ring 3 that is arranged on the floating ring below. The mesh body 3 is connected between the floating ring 1 and the bottom ring and in the middle of the bottom ring. The floating ring 1 is composed of several telescopic units. In this embodiment, a total of eight telescopic units are provided. The eight telescopic units are connected end to end to form a ring structure. The telescopic unit includes a first telescopic body 6 and a second telescopic body 7 that can move relative to the first telescopic body. The first telescopic body 6 is an arc-shaped cylindrical structure. One end of the first telescopic body 6 is closed and the other end is open. Above the first tel...

Abstract

The invention discloses a lifting net box with an adjustable water wing. The lifting net box is characterized by comprising a water wing capable of sinking and floating, a foundation ring arranged below the water ring and capable of sinking and floating and a net body arranged between the water wing and the bottom ring, and the water wing is composed of several telescopic units connected end to end and capable of extending or retracting under the pneumatic control. According to the lifting net box, two modes that the water wing can be adjusted and the net box can sink to the seabed are adoptedto resist stormy waves on the sea of different strengths, and the problem that only when a traditional net box sinks below the sea surface, can the stormy waves be avoided, and the stormy wave resistance mode is single are solved.

Description

technical field [0001] The invention relates to a net cage, in particular to a lifting net cage with adjustable floating ring size. Background technique [0002] Deep-sea cage culture is a culture technology that has developed rapidly in the past ten years. Due to the advantages of low environmental impact and high return rate, deep sea cage culture has been widely promoted. Due to the deep-sea cage culture process, the cages need to be placed in deep water areas, and the sea conditions in deep water areas are relatively harsh, and the cages are often affected by wind and waves. [0003] When dealing with the influence of some big wind and waves, the net cage avoids the wind and waves by descending below the sea surface, and floats to the sea surface after the wind and waves pass. Although this anti-wind and wave method can effectively reduce the impact of wind and waves, it also has the following shortcomings: first, after the net cage sinks below the sea surface, it is i...
