Embodiment 1

[0050] Please refer to Figure 1 to Figure 6 , Embodiment 1 of the present invention is:

[0051] A kind of deep-water net cage that can quickly change nets, comprising a net cage frame 1, an installation assembly 2, a net clothing assembly 3 and a winding device 4, wherein the net cage frame 1 forms an internal breeding space 11, and the cage frame 1 The bottom is fixedly provided with a bottom net.

[0052] In the present embodiment, the net cage frame 1 is a polygonal net cage structure, and at least one set of installation assembly 2, net clothing assembly 3 and winding device 4 are arranged on each side of the net cage frame 1, such as figure 1 The hexagonal cage structure shown has at least six sets of installation components 2, net clothing components 3 and winding devices 4. At the same time, the cage frame 1 and the installation assembly 2 are all steel structures, which increases the stability of the aquaculture water body and the strength of the cage structure, an...

Embodiment 2

[0057] Please refer to Figure 1 to Figure 6 , the second embodiment of the present invention is:

[0058] A kind of deep-water net cage that can quickly replace the net gear, on the basis of the above-mentioned embodiment one, such as Figure 2-Figure 3 It can be seen that each pair of sliding brackets includes two oppositely disposed sliding pieces 21, so that the mounting assembly 2 is provided with two sliding pieces 21 on both sides, so that one sliding piece 21 on each side corresponds to one on the other side. The sliding member 21 forms a pair of sliding brackets, that is, there are two pairs of sliding brackets.

[0059] Such as image 3 As shown, each sliding member 21 is provided with a first through hole 211 and a sliding opening 212 opened on the side facing the other sliding member 21; Figure 4 As shown, the net assembly 3 includes a net body 31 and sliding parts 32 arranged on both sides of the net body 31 . Wherein, the size of the sliding part 32 is small...

Embodiment 3

[0066] Please refer to Figure 1 to Figure 6 , Embodiment three of the present invention is:

[0067] A kind of deep-water net cage that can change net gear quickly, on the basis of above-mentioned embodiment two, such as Figure 5 with Image 6 As shown, in this embodiment, a bottom clip 5 is also provided between the sliding bracket and the directional wheel 42; wherein, the bottom clip 5 is provided with a second through hole 51 for the traction rope 41 to pass through and a second through hole 51 near the sliding bracket. One side is provided with a clamping slot 52 that is recessed toward the direction of the orientation wheel 42 .

[0068] Like this, traction rope 41 passes the second through hole 51 of bottom clip 5, and when traction rope 41 pulls net clothing assembly 3 to slide down to the bottom, net clothing assembly 3 is clamped in clamping draw-in groove 52, to The net clothing assembly 3 has a clamping and fixing effect, so that the net will not swing and fal...

Abstract

The invention discloses a deepwater net cage capable of quickly replacing a netting gear. The net cage comprises a net cage framework, mounting assemblies, netting assemblies and winding devices, thenet cage framework forms an internal culture space, and the bottom netting gear is fixedly arranged at the bottom of the net cage framework; a plurality of sets of mounting assemblies are tightly arranged on the net cage framework along the outer edge of the internal culture space; each mounting assembly is provided with at least two pairs of sliding supports, and each pair of sliding supports isconnected with the corresponding netting assembly in a sliding manner; and at least one winding device is arranged at the corresponding position of each mounting assembly, and each winding device is detachably connected with the netting assembly in the corresponding mounting assembly so as to drive the netting assembly to be wound. The labor intensity of netting gear replacement and netting gear carrying can be reduced, netting gear replacement is facilitated, the large-scale net cage is achieved, and therefore the problem of existing netting gear replacement is solved.

Description

technical field [0001] The invention relates to the technical field of marine aquaculture, in particular to a deep-water net cage capable of rapidly replacing net gear. Background technique [0002] Mariculture is an important business model and an important source of high-quality protein. In mariculture, one of the most labor-intensive tasks is cleaning the nets of the breeding cages. In the cultivation of marine products, changing nets is a labor-intensive task. In marine aquaculture, the cage nets will be attached by shellfish and seaweed in the ocean. The higher the temperature of the seawater, the faster these attachments will grow. If they are not removed in time, they will block the mesh and cause seawater exchange. Poor, resulting in a series of problems such as hypoxia. Moreover, during the growth process of farmed fish from small to large, the net gear must also be replaced accordingly. Therefore, no matter what kind of structure the marine net cage is, after a ...
