Embodiment 1

[0037] Such as Figure 1 to Figure 4 As shown, the deep-water net cage with a front streamlined floating tube outer frame according to the first embodiment of the present invention includes a floating tube frame 1, a netting 2 and an anchoring system. The floating tube frame 1 floats on the sea level SL, and the top of the netting 2 The floating pipe frame 1 is connected with a net weight mound 3 at the bottom to form a space for mariculture.

[0038] The floating pipe frame 1 of the first embodiment is provided with a front streamlined floating pipe outer frame. The front streamlined floating pipe outer frame is composed of a front connecting piece 101, two convex arc-shaped main floating pipes 102, and two elbow connecting pieces 103 And the rear main floating pipe 104, one end of the two convex arc-shaped main floating pipes 102 is connected to the front connecting piece 101, and the other end is connected to the two main floating pipes 104 through the two elbow connecting pie...

Embodiment 2

[0058] Such as Figure 7 As shown, the deep-water net cage of the second embodiment of the present invention is basically the same as that of the first embodiment, and their differences are: in the second embodiment, the mooring system of the deep-water net cage also includes a float 7 and a float cable 8; The upper end is connected to the tethering point 1a through the float 7 and the float cable 8, that is, the upper end of the anchor rope 5 and one end of the float cable 8 are respectively connected to the float 7, and the other end of the float cable 8 is connected to the tethering point 1a, and the float 7 floats in the sea. On the plane SL. The working principle of the second embodiment is basically the same as that of the first embodiment, and the increase of the float 7 and the float cable 8 can further buffer the instantaneous stress on the deep-water cage and improve the stability of the deep-water cage.

Embodiment 3

[0060] The deep water net cage of the third embodiment of the present invention can adopt any of the construction methods described in the first or second embodiment. The difference from them is that in the third embodiment, the length of the anchor rope 5 is such that the anchor rope 5 is It forms an angle α of 17° with the sea level SL under tension.

Abstract

The invention discloses a deepwater net cage with a front streamline floating pipe outer frame. The deepwater net cage comprises a floating pipe frame, netting and a mooring system, the floating pipe frame is provided with the front streamline floating pipe outer frame, the front streamline floating pipe outer frame is composed of a front connecting piece, two outwards-protruding arc-shaped main floating pipes, two bent pipe connecting pieces and a back main floating pipe, the front ends of the two outwards-protruding arc-shaped main floating pipes are connected through the front connecting piece, and the back ends of the two outwards-protruding arc-shaped main floating pipes are connected with the two ends of the back main floating pipe respectively through the two bent pipe connecting pieces; in addition, a box tying point is arranged on the front connecting piece. The mooring system comprises an anchor, an anchor rope and an anchor rope weight, the anchor is sunk into the seabed, the lower end of the anchor rope is connected with the anchor, the upper end of the anchor rope is connected with the box tying point, the anchor rope weight is tied and hung on the anchor rope, and the length of the part, located between a tying and hanging point of the anchor rope weight and the upper end of the anchor rope, of the anchor rope approximates the lowest water level water depth of the position of the anchor.

Description

Technical field [0001] The invention relates to a seawater net cage culture equipment, in particular to a deep water net cage with a front streamline floating tube outer frame. Background technique [0002] In 1998, my country’s first deep-water cage was introduced from Norway, and its mooring system was a multi-point array suspended mooring system; in 2000, my country improved the multi-point array suspended mooring system to achieve direct-line multi-point array mooring, but the essence is still It is a multi-point array mooring system and has been in use until 2006; in 2006, in the practice of the direct-connected multi-point array mooring system, the combined cage was split to form the current single-box direct-connected multi-point mooring system, which is still in use today . [0003] The mooring system is the foundation for the survival of deep-water cages. The second technical improvement is not only simpler than the original design in terms of construction technology, but ...
