[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 4 The utility model shows a schematic diagram of the entire structure of an aquaculture cage, please refer to Figure 1-Figure 4 The present embodiment provides an aquaculture cage, comprising a cage body 100, wherein the cage body 100 is divided into two layers, namely an upper culture layer 110 and a lower sedimentation layer 120, wherein a partition 130 is provided between the culture layer 110 and the sedimentation layer 120, wherein a mounting frame 150 is fixed to the top of the cage body 100, wherein a main shaft 200 is vertically arranged at the center of the cage body 100 and the upper end of the main shaft 200 is mounted on the mounting frame 150 through a bearing, and wherein the main shaft 200 is hollow in structure, and wherein the main shaft 200 is provided with a plurality of hollow holes. The lower end of the shaft 200 extends into the sedimentation layer 120 and a sewage suction pipe 210 is fixed horizontally. The sewage suction pipe 210 is connected to the main shaft 200. The sewage suction pipe 210 spans the bottom of the sedimentation layer 120, and a plurality of suction nozzles 2101 are arranged at the bottom of the sewage suction pipe 210 along its length. A rotating drive assembly 300 that can drive the main shaft 200 to rotate is arranged at the upper end of the mounting frame 150. A suction assembly 400 that is connected to the upper end of the main shaft 200 and is used to suck the main shaft 200 is also arranged on the mounting frame 150.

[0022] A support frame 140 for supporting the partition net 130 and the main shaft 200 is also fixed to the lower inner part of the cage body 100. The central part of the support frame 140 also has a positioning sleeve 220 movably mounted on the outside of the main shaft 200. Here, the partition net 130 can prevent fish and other aquatic products from entering the sediment layer 120 and coming into direct contact with feces and debris, thereby achieving the effect of stratified purification aquaculture; in addition, since the main shaft 200 extends longitudinally for a long time, in order to prevent the main shaft 200 from swinging badly when driving the sewage suction pipe 210 to rotate, the main shaft 200 can drive the sewage suction pipe 210 to form a stable radial rotation through the cooperation of the support frame 140 and the positioning sleeve 220.

[0023] The cage body 100 adopts a circular structure, and the main axis 200 is coaxially arranged with the cage body 100. In this embodiment, the breeding cage here adopts a circular shape. In this way, when the sewage pipe 210 rotates horizontally, it can cover the main area of ​​the bottom of the cage, making the suction and cleaning of feces more comprehensive and thorough.

[0024] A protective box cover 500 for installing the rotating drive component 300 and the suction component 400 is also fixed to the upper end of the mounting frame 150; the rotating drive component 300 includes a motor 310 fixed to the inner side of the protective box cover 500, a rotating shaft 320 located at the bottom output end of the motor 310, a driving wheel 330 arranged on the outer side of the rotating shaft 320, a passive wheel 340 arranged on the outer side of the main shaft 200 and parallel to the driving wheel 330, and a belt 350 connected to the driving wheel 330 and the passive wheel 340. When in use, the motor 310 can drive the driving wheel 330 to rotate through the rotating shaft 320, and the driving wheel 330 drives the passive wheel 340 and the main shaft 200 to rotate synchronously through the belt 350. In this way, the main shaft 200 can drive the sewage extraction pipe 210 to rotate horizontally at a uniform speed, and the structure is simple and easy to maintain.

[0025] The suction assembly 400 includes a sealing sleeve 410 sleeved on the upper end of the rotating shaft 320 and fixed on the inner side of the protective box cover 500, a connecting pipe 420 connected to the sealing sleeve 410 at the lower end, a sludge pump 430 installed on the upper end of the protective box cover 500 and the water inlet end is connected to the upper end of the connecting pipe 420, and a delivery pipe 440 connected to the water outlet end of the sludge pump 430. When in use for cleaning, the started sludge pump 430 can suck the inner cavity of the main shaft 200 through the connecting pipe 420. At the same time, with the matching of the sealing sleeve 410, the rotating main shaft 200 can be prevented from driving the connecting pipe 420 to rotate. The sewage suction pipe 210 can effectively suck out feces and debris accumulated at the bottom of the sediment layer 120 through the suction nozzle 2101 under the suction of the main shaft 200. At the same time, the continuously rotating sewage suction pipe 210 can form a covering cleaning on the bottom of the sediment layer 120, which is simple and efficient.

[0026] In summary, in an aquaculture cage according to the present embodiment, when in use, the started sludge pump 430 can suck the inner cavity of the main shaft 200 through the connecting pipe 420, and at the same time, the sealing sleeve 410 can prevent the rotating main shaft 200 from driving the connecting pipe 420 to rotate, and the sewage pipe 210 can effectively suck out the feces and debris accumulated at the bottom of the sediment layer 120 through the suction nozzle 2101 under the suction of the main shaft 200, and at the same time, the continuously rotating sewage pipe 210 can form a covering cleaning for the bottom of the sediment layer 120, which is simple and efficient, and the partition net 130 can prevent fish and other aquatic products from entering the sediment layer 120 and directly contacting with feces and debris, thereby achieving the effect of layered purification aquaculture.

[0027] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention.
