Embodiment 1

[0038] Such as Figure 1 to Figure 4-2 As shown, the deep-water net cage with the single-point mooring system of Embodiment 1 of the present invention includes a floating pipe frame 1, a net clothing 2 and an anchoring system. The floating pipe frame 1 floats on the sea level SL, and the top of the net clothing 2 is connected to a floating A net weight 3 is hung on the bottom of the pipe frame 1 to form a space for seawater cultivation.

[0039] The mooring system of the first embodiment includes an anchor 4, an anchor rope 5 and an anchor rope weight 6; the floating pipe frame 1 is provided with a mooring point 1a, the anchor 4 sinks into the seabed SF, and the lower end of the anchor rope 5 is connected to the anchor 4, The upper end is connected to the mooring box point 1a, and the rope length of the anchor rope 5 is such that the anchor rope 5 forms an angle α of 25° with the sea level SL in a tight state; the anchor rope weight 6 is hung on the anchor rope 5, and the anch...

Embodiment 2

[0059] Such as Figure 7 Shown, the deep-water net cage of embodiment two of the present invention is substantially the same as embodiment one, and their difference is: in the present embodiment two, the mooring system of deep-water net cage also comprises floater 7 and float cable 8; The upper end is connected to the mooring point 1a by the buoy 7 and the buoy cable 8, that is: the upper end of the anchor rope 5 and one end of the buoy cable 8 are respectively connected to the buoy 7, and the other end of the buoy cable 8 is connected to the mooring point 1a, and the buoy 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 of the deep-water net cage and improve the stability of the deep-water net cage.

Embodiment 3

[0061] The deep-water cage of the third embodiment of the present invention can adopt any one of the construction methods described in the first or second embodiment. The difference is that in the third embodiment, the length of the anchor rope 5 is such that the anchor rope 5 is In the tense state, it forms an angle α of 17° with the sea level SL.

Abstract

The invention discloses a deepwater net cage with a single-point mooring system. The deepwater net cage comprises a floating pipe frame (1), netting (2) and the mooring system; the floating pipe frame (1) floats on the sea level (SL), the top of the netting (2) is connected with the floating pipe frame (1), and a netting weight (3) is tied and hung at the bottom of the netting (2) so as to form space for mariculture; the mooring system comprises an anchor (4), an anchor rope (5) and an anchor rope weight (6); the floating pipe frame (1) is provided with a box tying point (1a), the anchor (4) is sunk into the sea floor (SF), the lower end of the anchor rope (5) is connected with the anchor (4), the upper end of the anchor rope (5) is connected with the box tying point (1a), the anchor rope weight (6) is tied and hung on the anchor rope (5), and the length of the part, located between a tying and hanging point of the anchor rope weight (6) and the upper end of the anchor rope (5), of the anchor rope (5) approximates the lowest water level water depth of the position of the anchor (4). The deepwater net cage is high in anti-typhoon capacity and risk prevention capacity.

Description

technical field [0001] The invention relates to a seawater net cage cultivation equipment, in particular to a deep water net cage with a single-point mooring system. Background technique [0002] In 1998, the mooring system of the deep-water net cage imported from Norway for the first time in my country was a multi-point array suspension mooring system; It is a multi-point array mooring system, which has been used until 2006; in 2006, in the practice of the linear multi-point array mooring system, the combined net cage was split to form the current single-box linear 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 secondary technical improvement is not only simpler than the original design in terms of construction technology, but also improves the anti-typhoon capability by two levels, from level 12 to level 14, and has achieved obvious technological progress and economic benefit...
