[0096] Further, under the driving of the bottom cleaning transmission assembly 600, the first rotating arm 502 and the second rotating arm 503 of the bottom cleaning assembly 500 are synchronously rotated around the vertical center of the middle column 102, and the two groups of rotating arms are in gapless contact with the inner wall and the bottom of the breeding tank body; during the synchronous clockwise or counterclockwise rotation of the first rotating arm 502 and the second rotating arm 503 driven by the rotating ring 501, the brushes reciprocally and circularly clean the surface of the bottom plate of the frame assembly 100.

[0097] The lifting frame 401 of the lifting cleaning assembly 400 has the functions of carrying the catching device and realizing directional driving of fish during vertical lifting in addition to cleaning the breeding tank body.

[0098] Specifically, a circle of fishing net frames 408 is vertically supported and connected to the periphery of each fish chasing opening on the lifting frame 401 through a plurality of short columns 409;

[0099] The fishing net pull plate 440 is slidingly connected to the fishing net frame 408 through a group of symmetrically distributed fifth holes 441 arranged at both ends of the fishing net pull plate 440, one end of the fishing net (not shown in the figure) is wound on the fishing net frame 408 on one side of the fish chasing opening, and the other end of the fishing net is fixedly connected to the fishing net hole 442 of the fishing net pull plate 440;

[0100] The fishing net pull plate 440 is reciprocally and vertically slid above the fishing net frame 408 under the driving of the catching driving device to cover the fish chasing opening on the lifting frame 401 or open the fish chasing opening; when the fish chasing opening is covered by the fishing net, the fish and other aquatic organisms in the breeding tank body are directionally driven upward or downward when the lifting frame 401 is lifted along the vertical center of the middle column 102, so as to realize catching or transfer to other breeding tank bodies or other breeding ships; when the fish chasing opening is opened, since the fishing net does not cover the lifting frame 401, the normal activity and growth of the fish and other aquatic organisms in the breeding tank body will not be affected during the lifting of the lifting frame 401 along the vertical center of the middle column 102.

[0101] Furthermore, the fishing drive device includes two sets of seventh pulleys 422, which are symmetrically distributed at opposite edges of the fish-driving opening and are driven and connected by the second winch 420 and the third winch 430 respectively. The second steel cable 421 and the third steel cable 431, which are connected to the driving ends of the second winch 420 and the third winch 430 respectively, are folded and connected to the seventh pulleys 422 on both sides of the fish-driving opening and then docked on the fishing net pull plate 440.

[0102] Specifically, each group of seventh pulleys 422 is mounted on a second pulley plate 415 mounted on the lifting frame 401 via a rotating shaft through the third pulley hole 416.

[0103] A pull plate joint 443 is fixedly installed on the fishing net pull plate 440, and the connecting ends of the second steel cable 421 and the third steel cable 431 are respectively fixed on the pull plate joint 443;

[0104] The second winch 420 and the third winch 430 can be installed at the bottom of the cable tray 103 respectively.

[0105] When the lifting frame 401 is stationary in the vertical direction, the second steel cable 421 and the third steel cable 431 are simultaneously driven to move in the same direction by the second winch 420 and the third winch 430 respectively. Thus, the fishing net is driven to move towards the fish-driving opening side of the lifting frame 401 by the pull plate joint 443, so as to cover the fishing net or open the fish-driving opening.

[0106] When the lifting frame 401 descends vertically along the middle column 102, the second winch 420 and the third winch 430 simultaneously release the second steel cable 421 and the third steel cable 431; when the lifting frame 401 rises vertically along the middle column 102, the second winch 420 and the third winch 430 simultaneously retract the second steel cable 421 and the third steel cable 431, thus achieving coordinated operation of the cleaning and capture devices without mutual interference.

[0107] Furthermore, at least one set of horizontally distributed pull plate holes 442 are provided on the fishing net pull plate 440, and one end of the fishing net is fixedly connected to the fishing net pull plate 440 through the pull plate holes 442.

[0108] like Figure 1 As shown, based on the overall structural design of the above-mentioned aquaculture tank, the aquaculture tank is placed on a deep-sea aquaculture vessel to realize the aquaculture and harvesting of various aquatic organisms.

[0109] Several aquaculture pods can be installed on the upper deck of the aquaculture vessel, with each pod's frame assembly 100 individually fixed to the upper deck;

[0110] Similarly, several culture bins can be installed on the ship plates inside the work ship, several frame body assemblies 100 are assembled together to form an integrated culture bin body structure, the side plates 101 of adjacent frame body assemblies 100 can be shared, and the plurality of frame body assemblies 100 are butted together to form a shared bin body side wall, so that the amount of side plates 101 can be saved accordingly; such an internal splicing type structure design can significantly save the amount of steel, and the effect is more obvious on a large culture work ship such as a 100,000-ton class and an 80,000 cubic meter culture water body.

[0111] In summary, the embodiments shown in the drawings are only preferred schemes for achieving the purpose of the present application. Those skilled in the art can be inspired by this and directly deduce other alternative structures that meet the design concept of the present application. Other structural features obtained thereby should also belong to the scope of the schemes described in the present application.
