Problems solved by technology

[0002] At present, deep-water cages in the northern part of the South my country Sea are mainly distributed in nearshore and offshore waters. Breakthroughs have been made in cage facilities and breeding technology. The operating water depth can reach 20-100m, and the structural safety rate can reach 14 under typhoon operating conditions. More than 90%, but the structural strength still needs to be improved, such as rationally designing the main frame structure, making full use of the mechanical characteristics of the main frame and wave flow, and effectively avoiding the damage caused by wind and waves on the surface, etc.

Embodiment approach

[0038] As a preferred embodiment of the present invention: in the case of no external force acting on the large deep-water net cage, the height of the upper floating frame immersed in seawater accounts for 1 / 2 to 3 / 5 of its total height.

[0039] In order to facilitate the adjustment of the buoyancy of the upper floating frame and the lower floating frame, and in order to cooperate with the existing deep-water cage floating frame construction process, to reduce the construction difficulty and construction cost of the longitudinal frame type main frame, as a preferred embodiment of the present invention:

[0040] The upper floating frame includes at least one upper floating tube frame 1 arranged horizontally, and for the case of including more than two upper floating tube frames 1, each upper floating tube frame 1 is progressively increased according to the horizontal cross-sectional area of ​​the enclosed space Sorting, then the former upper floating tube frame 1 is located in ...

Embodiment 1

[0045] Such as Figure 1 to Figure 4 As shown, Embodiment 1 of the present invention is based on the above-mentioned inventive concepts, and adopts the following specific solutions:

[0046] The upper floating frame includes an upper floating tube frame 1, and the lower floating frame includes a lower floating tube frame 2; the I-shaped frame 3 is correspondingly provided with an upper casing 31 and a lower casing 32 arranged in parallel. The connecting frame 33 of the word frame 3 is a plate connected between the upper casing 31 and the lower casing 32 .

[0047] The above-mentioned inventive concept is specifically described below by four examples:

Embodiment 2

[0049] Such as Figure 5 to Figure 7 As shown, the second embodiment of the present invention is based on the above-mentioned inventive concepts, and adopts the following specific solutions:

[0050] The upper floating frame includes two upper floating tube frames 1, and the lower floating frame includes two lower floating tube frames 2; the I-shaped frame 3 is correspondingly provided with two upper casings 31 and two lower casings 32 arranged in parallel , the connecting frame 33 of the I-shaped frame 3 is provided with five flow pipes 331 for the passage of water, and is provided with two upper casings 31, two lower casings 32, and five flow pipes 331 connected into one. A connecting plate 332, wherein five flow pipes 331 are parallel to the upper casing 31 and the lower casing 32, the first flow pipe 331 is located between the two upper casings 31, and the second flow pipe 331 is located between the two upper casings 31. Between the lower casings 32, the third flow pipe 3...

Abstract

The invention discloses a large-scale deep-water net cage adopting a longitudinal skeleton-type main frame, which is provided with a main frame, an anchoring system for anchoring the main frame, and a net hanging under the main frame, and is characterized in that : the main frame is a longitudinal frame type main frame, which is provided with an upper floating frame and a lower layer floating frame; the upper layer floating frame is fixed with the lower layer floating frame, and the lower layer floating frame is located at the The bottom of the upper floating frame; and, in the case of no external force acting on the large deep-water cage, the upper floating frame of the longitudinal frame type main frame floats on the sea surface, and the lower floating frame sinks under the sea surface. The invention can enhance the stability of the main frame, reduce the impact displacement of the wave on the main frame, effectively reduce the inertia force of the main frame moving with the waves, reduce the inertia restoring force and impact effect of the anchor rope on the main frame, and avoid the impact of the anchor rope on the main frame. Excessive loading of the frame by force.

Description

technical field [0001] The invention relates to a large deep-water net cage adopting a longitudinal skeleton type main frame. Background technique [0002] At present, deep-water cages in the northern part of the South my country Sea are mainly distributed in nearshore and offshore waters. Breakthroughs have been made in cage facilities and breeding technology. The operating water depth can reach 20-100m, and the structural safety rate can reach 14 under typhoon operating conditions. However, the structural strength still needs to be improved, such as rationally designing the main frame structure, making full use of the mechanical characteristics of the main frame and wave flow, and effectively avoiding the damage caused by wind and waves on the surface. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-scale deep water net cage adopting a longitudinal skeleton type main frame. [0004] To solve the problem...
