Abstract
Description
Technical Field
[0001] The present invention relates to a telescopic breeding tank with an internally expandable or contractible space and a breeding workboat applying such a flexible design for adjusting the breeding space, belonging to the technical field of aquaculture. Background Art
[0002] Currently, existing flowing water breeding and recirculating water breeding technologies have been widely applied in the field of aquaculture. Based on breeding containers, feed feeding, and water treatment equipment in a specific space, the breeding water environment can be improved accordingly, the breeding density of water bodies can be increased, and ultimately higher growth rates and yields can be obtained.
[0003] As in the following previously published Chinese patent application, with the application number 2021106894099 and the title of fully mobile three-dimensional aquatic organism breeding system, a submersion three-dimensional device and control method suitable for breeding various aquatic organisms are proposed. Through the design and use of several modular and mobile small breeding containers arranged in a queue, during the sequential movement of all breeding containers, the management of multiple operations such as feeding, catching, sorting, and cleaning is implemented, in order to achieve the dynamic and refined management of the entire breeding cycle of aquatic organisms, and accordingly improve the yield of breeding organisms per unit area and the utilization rate of water bodies, so as to solve the mechanization and automation technical problems of feeding, catching, sorting, and cleaning in the submersion multi-layer breeding mode. The fully mobile three-dimensional aquatic organism breeding system includes an outer frame assembly, several small breeding containers arranged in a circular queue, an external lateral movement assembly, an external vertical movement assembly, and a circulation drive assembly.
[0004] The above-mentioned existing technologies still adopt a closed breeding mode inside the ship's cabin. The breeding space is limited by the ship's own load. The breeding density of a single cabin is still low, and at the same time, it is difficult to significantly improve problems such as the high construction cost and energy consumption of the breeding workboat. With the continuous development of large deep-sea breeding facilities, especially large breeding workboat technologies, how to optimize the utilization rate of breeding space, increase the breeding water volume of a single workboat, and improve the automation breeding efficiency has become particularly prominent.
[0005] In view of this, this patent application is specifically proposed. Summary of the Invention

Through the telescopic cabin structure design, the characteristics of being easy to carry and transport during transfer and transportation are realized. At the same time, the natural water environment is fully utilized for breeding to meet the design purposes of improving breeding efficiency, reducing the structural difficulty of the workboat, and reducing energy consumption.

[0008] Further, a set of chutes are respectively arranged on both sides of the trough plate, and the valve is hinged to the trough plate and reciprocates along the chutes to open and close the through holes on the net plate.
[0009] Further, a mounting plate is fixedly connected to the top of the upper frame of the telescopic frame component located on the outermost side after mutual nesting, and a first pin is arranged on the mounting plate and can axially extend or retract along the surface of the mounting plate; the bottom end of the second lifting chain is fixedly connected to the third lower frame, and its top end passes through the mounting plate and is connected to the first lifting chain; the second lifting chain has a plurality of lifting chain holes arranged in sequence, and when all the telescopic frame components are stretched or folded, the first pin extends into one of the lifting chain holes to lock the second lifting chain.
[0010] Further, a plurality of groups of rollers are arranged on the guide columns of the telescopic frame components located on the relatively inner side after mutual nesting and are in rolling contact with the guide columns of the adjacent telescopic frame components located on the outer side.
[0011] Further, when all the telescopic frame components are stretched along the axial center, the trough plate and the net plate between adjacent telescopic frame components are in clearance fit.
[0012] Further, when all the telescopic frame components are folded along the axial center, the horizontal axial centers of the valves between adjacent telescopic frame components are all on the same straight line.
[0013] Based on the design of the structure and connection relationship of the above telescopic aquaculture bin, the present application also proposes an aquaculture workboat applying such telescopic aquaculture bins. The aquaculture workboat has several built-in cabins for temporarily raising aquatic organisms transferred from the telescopic aquaculture bins; several telescopic aquaculture bins are arranged on one or both sides outside the hull, and the telescopic aquaculture bins are placed in the open water environment outside the workboat for aquaculture and management.

[0058] The telescopic aquaculture tank described in this application can be applied to aquaculture workboats or deep - sea and far - sea aquaculture platforms for culturing various types of aquatic organisms. In this telescopic aquaculture tank, full - cycle aquaculture from fry to catch, automated sorting, and catch operations can be realized to achieve dynamic and refined aquaculture management.
[0059] Embodiment 1, as Figures 1 to 26 shown, the aquaculture workboat 100 carrying the telescopic aquaculture tank 200 includes an internal cabin, which can be used to temporarily raise the aquatic organisms transferred from the telescopic aquaculture tank 200 during mooring or navigation; several telescopic aquaculture tanks 200 are arranged on one or both sides outside the hull of the aquaculture workboat 100, and the telescopic aquaculture tanks 200 are placed in the open water environment outside the workboat for aquaculture and management.
[0060] Specifically, a fixed array of horizontally distributed fixing frames 101 is installed on the outer side of the hull of the aquaculture workboat 100, and a set of lifting frames 102 is fixed vertically above each set of fixing frames 101;
[0061] An inlet - outlet fish port 104 communicating with the internal cabin is arranged on the side of the aquaculture workboat 100. Through this inlet - outlet fish port 104, the aquatic organisms cultured in the telescopic aquaculture tank 200 can be transferred to the internal cabin, or the aquatic organisms temporarily raised in the internal cabin can be transferred to the telescopic aquaculture tank 200 located in the external open water area;
[0062] A winch 105 is fixedly connected to the lifting frame 102. The output shaft of the winch 105 is wound and connected with a first lifting chain 106, and the end of the first lifting chain 106 is connected to the telescopic aquaculture tank 200; under the drive of the winch 105, the telescopic aquaculture tank 200 can be vertically lifted or retracted through the first lifting chain 106;
[0063] On the side of the fixing frame 101, a plurality of limiting blocks 110 are hinged through a fixedly connected limiting block support plate 107. The limiting block 100 can rotate vertically around the hinge point with the limiting block support plate 107. Specifically, the limiting block support plate 107 has a limiting hole 108 penetrating in the horizontal axial direction. Both ends of the limiting shaft 109 are hinged to the limiting holes 108 on both sides, and the middle part of the limiting shaft 109 is fixedly connected to the limiting block 110.
[0064] In this embodiment, the method of driving the vertical rotation of the limiting block 110 can be arbitrarily selected based on the prior art. For example, a transmission method of using a cylinder or a servo motor to drive the limiting shaft 109 can be adopted. When the output shaft of the cylinder or the servo motor drives the limiting shaft 109 to rotate around a fixed axis, driven by the limiting shaft 109, the limiting block 110 rotates around the axial center of the limiting shaft 109, thereby changing its own positioning angle relative to the fixing frame 101. When the limiting block 110 rotates vertically to the vertical state, the process of the winch 105 lifting or retracting the telescopic aquaculture tank 200 vertically is not hindered at all. When the limiting block 110 rotates to the horizontal state (as Figure 26 shown), the telescopic aquaculture tank 200 can be integrally erected on the limiting block 110. The limiting block 110 plays an upward supporting role and can assist in realizing the vertical positioning of the telescopic aquaculture tank 200 without slipping.
[0065] On the fixing frame 101, a mooring ring 111 is fixedly connected to the side away from the aquaculture workboat 100. Other adjacent parked ships can be moored by using a cable through this mooring ring 111.
[0066] The described telescopic aquaculture tank 200 includes a first telescopic frame assembly 210, a second telescopic frame assembly 230, and a third telescopic frame assembly 250 that are nested and connected in sequence vertically.
[0067] Among them, the first telescopic frame assembly 210 has a first upper frame 211 and a first lower frame 213. A plurality of first guiding columns 214 are connected between the first upper frame 211 and the first lower frame 213 vertically. A first mesh plate 215 is connected between two adjacent first guiding columns 214.
[0068] A first trough-shaped plate 220 is connected through the first mesh plate 215. The first trough-shaped plate 220 is docked with the fish inlet / outlet 104 to form a transfer interface channel between the telescopic aquaculture tank 200 and the aquaculture workboat 100. A set of first sliding grooves 221 are respectively arranged on both sides of the first trough-shaped plate 220. A first valve 222 is hinged to the first trough-shaped plate 220 and reciprocally slides along the first sliding grooves 221 to open or close the through hole on the first mesh plate 215.
[0069] A first hole 212 is arranged vertically on the first upper frame 211.
[0070] A first limiting plate 227 connected vertically in an array is provided on the first lower frame 213;
[0071] The mounting plate 224 with an overall cross-shaped structure is fixedly connected to the top of the first upper frame 211. A first pin shaft 216 and several second holes 217 are provided at the end corners of the mounting plate 224, a third hole 223 is provided at the center of the mounting plate 224, and a fourth hole 225 is provided at the side of the mounting plate 224;
[0072] One end of the rotating plate 218 is hinged to the first pin shaft 216 through a rotating plate hole 228, and several first grooves 219 are provided on the side of the rotating plate 218;
[0073] A first pin 226 is provided on the mounting plate 224 adjacent to the third hole 223, and the first pin 226 can axially extend or retract along the surface of the mounting plate 224; in this embodiment, the method of driving the first pin 226 to achieve linear motion in the horizontal direction can be arbitrarily selected based on the prior art, such as adopting a transmission method of driving the first pin 226 to linearly move by a cylinder or a servo motor, which will not be elaborated here;
[0074] The mounting plate 224 can be connected or disassembled with the first upper frame 211 by bolts respectively passing through the fourth hole 225 and the first hole 212;
[0075] A first screw hole 103 is provided on the fixing frame 101. By bolts respectively passing through the first screw hole 103, the first hole 212, and the fourth hole 225, the first upper frame 211 and the mounting plate 224 can be sequentially installed and fixed on the fixing frame 101, thereby realizing the connection between the first telescopic frame assembly 210 and the aquaculture workboat 100.
[0076] The second telescopic frame assembly 230 includes a second upper frame 231 and a second lower frame 232. An array of second guide columns 233 are connected vertically between the second upper frame 231 and the second lower frame 232, and second net plates 234 are connected between two adjacent second guide columns 233;
[0077] A second trough-shaped plate 235 is connected through the second net plate 234 in a penetrating manner, and a second limiting plate 241 is fixedly connected to the second lower frame 232;
[0078] A set of second chutes 236 are respectively provided on both sides of the second trough-shaped plate 235. The second valve 237 penetrates vertically through a first notch 238 on the second upper frame 231, and both sides of the second valve 237 are slidably connected to the second chutes 236;
[0079] First locking pins 242 are respectively fixedly connected to the end corners of the second upper frame 231;
[0080] A plurality of first roller brackets 243 are fixedly connected to the second guide post 233. The first roller 240 is hinged to the first roller bracket 243 through the second pin shaft 239 and rotates around its axial direction.
[0081] When the second telescopic frame assembly 230 is sleeved in the first telescopic frame assembly 210, first, the mounting plate 224 is removed, and then the second telescopic frame assembly 230 is integrally sleeved into the first telescopic frame assembly 210 vertically upward. When the bottom of the second upper frame 231 supports on the first limiting plate 227, the second telescopic frame assembly 230 is sleeved in place, and the first limiting plate 227 provides a vertically upward supporting force to the second telescopic frame assembly 230 through the second upper frame 231.
[0082] During the above-mentioned sleeving and positioning process, or when the second telescopic frame assembly 230 is vertically lifted from the first telescopic frame assembly 210, the first roller 240 of the second telescopic frame assembly 230 rolls and contacts the inner side of the first guide post 214 of the first telescopic frame assembly 210.
[0083] The third telescopic frame assembly 250 described has a third upper frame 251 and a third lower frame 252. A plurality of third guide posts 253 are connected vertically between the third upper frame 251 and the third lower frame 252. Third mesh plates 254 are connected between two adjacent third guide posts 253, and a bottom mesh plate 255 is fixedly connected to the bottom of the third lower frame 252.
[0084] A third channel plate 258 is connected through the third mesh plate 254. A set of third chutes 259 are respectively arranged on both sides of the third channel plate 258. Both sides of the third valve 260 are slidably connected to the third chutes 259 and can slide vertically back and forth.
[0085] In this embodiment, the driving methods for driving the first valve 222, the second valve 237, and the third valve 260 to slide vertically along their chutes can be arbitrarily selected based on the prior art, such as adopting a mechanical transmission method of cable pulling, a motor or cylinder transmission method.
[0086] Second locking pins 265 are fixedly connected to the respective end corners of the third upper frame 251.
[0087] A plurality of second roller brackets 262 are fixedly connected to the top of the third guide post 253. The second roller 263 is hinged to the second roller bracket 262 through the third pin shaft 263 and rotates around its axial direction.
[0088] Several additional plates 266 are detachably connected to the outer edge of the third upper frame 251; specifically, the third upper frame 251 has a fifth hole 267, and the additional plate 266 is provided with a sixth hole 268. The additional plate 266 is detachably connected to the third upper frame 251 by bolts passing through the fifth hole 267 and the sixth hole 268 in sequence; after the third telescopic frame assembly 250 is sleeved into the second telescopic frame assembly 230, the additional plate 266 is fixedly connected to the third upper frame 251.
[0089] The bottom end of the second suspension chain 256 is fixedly connected to the third lower frame 252, and its top end passes through the third hole 223 at the center of the mounting plate 224 and is connected to the first suspension chain 106; the second suspension chain 256 has several suspension chain holes 257 arranged in sequence; when the telescopic aquaculture bin 200 is disassembled as a whole and removed from the aquaculture workboat 100, the connection between the first suspension chain 106 and the second suspension chain 256 can be untied.
[0090] When the third telescopic frame assembly 250 is sleeved onto the second telescopic frame assembly 230, first remove the additional plate 266, and then the third telescopic frame assembly 250 is integrally sleeved vertically upward. When the bottom of the third upper frame 251 is supported on the second limiting plate 241, the third telescopic frame assembly 250 is sleeved in place, and the second limiting plate 241 provides a vertically upward supporting force to the third telescopic frame assembly 250 through the third upper frame 251.
[0091] During the above sleeving process, or when the third telescopic frame assembly 250 is vertically lifted from the second telescopic frame assembly 230, the second roller 263 of the third telescopic frame assembly 250 rolls into contact with the inner side of the second guiding column 233 of the second telescopic frame assembly 230.
[0092] After the third telescopic frame assembly 250 is sleeved and positioned inside the second telescopic frame assembly 230, then the additional plate 266 is fixedly connected to the third upper frame 251, and the mounting plate 224 is fixedly connected between the first upper frame 211 and the fixing frame 101.
[0093] According to the above structural design and connection relationship, when the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are sleeved in sequence, under the supporting action of the second limiting plate 241, a stable vertical positioning is formed between the third telescopic frame assembly 250 and the second telescopic frame assembly 230, and the two remain relatively stationary; under the supporting action of the first limiting plate 227, a vertical positioning is formed between the second telescopic frame assembly 230 and the first telescopic frame assembly 210; under the fixed connection of the mounting plate 224, the first telescopic frame assembly 210 is simultaneously positioned stably in the vertical and horizontal directions with respect to the fixing frame 101, and finally the fixed connection between the telescopic aquaculture bin 200 as a whole and the fixing frame 101 is realized.
[0094] Further, to prevent the cultured aquatic organisms from escaping between the components constituting the telescopic culture tank 200, when the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are successively sleeved and fully extended in sequence, there is a clearance fit between the second trough-shaped plate 235 and the first mesh plate 215, and there is a clearance fit between the third trough-shaped plate 258 and the second mesh plate 234; when the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are successively sleeved in place, a clearance fit relationship is formed between them in the horizontal direction to constitute a relatively enclosed culture space;
[0095] Further, to optimize the transfer operation of the cultured aquatic organisms into the built-in cabin of the culture workboat 100, or when it is necessary to implement the transfer operation of moving the cultured aquatic organisms out of the telescopic culture tank in case of unknown risks, when the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are successively sleeved and fully folded in sequence, the horizontal axial centers of the first valve 222, the second valve 237, and the third valve 260 are all on the same straight line.
[0096] Based on the above structural design of the telescopic culture tank 200, the present application also proposes the following culture method:
[0097] Apply the telescopic culture tank 200 to the culture workboat 100 or the deep-sea and far-sea culture platform, and implement the full-cycle culture management from fry to catching in the telescopic culture tank 200;
[0098] Specifically, when the culture workboat 100 is sailing, transfer the cultured aquatic organisms in the telescopic culture tank 200 to the built-in cabin for temporary culture; when the culture workboat 100 is stationary, culture the aquatic organisms in the telescopic culture tank 200 on one or both sides outside its hull. When culturing, the telescopic culture tank 200 is placed in the open water environment outside the workboat.
[0099] Fix the telescopic culture tank 200 on the outer side of the hull of the culture workboat 100 through the fixing frame 101. Specifically, fix the lifting frame 102 above the fixing frame 101 vertically. Driven by the winch 105, the telescopic culture tank 200 can be vertically lifted or retracted through the first lifting chain 106;
[0100] After lifting the telescopic culture tank 200, place it on the limiting block 110 in a horizontal state on the fixing frame 101, and the telescopic culture tank 200 is integrally placed on the fixing frame 101.
[0101] Further, the telescopic culture tank 200 includes a first telescopic frame assembly 210, a second telescopic frame assembly 230, and a third telescopic frame assembly 250 that are nested and connected to each other along the vertical center;
[0102] The second telescopic frame assembly 230 is sleeved in the first telescopic frame assembly 210. First, remove the mounting plate 224, and then the second telescopic frame assembly 230 is integrally sleeved into the first telescopic frame assembly 210 vertically upward. When the bottom of the second upper frame 231 is stacked on the first limiting plate 227, the sleeving of the second telescopic frame assembly 230 is completed. The first limiting plate 222 provides a vertically upward supporting force to the second telescopic frame assembly 230 through the second upper frame 231. During the above sleeving process, the first rollers 240 of the second telescopic frame assembly 230 rollingly contact the inner sides of the first guiding columns 214 of the first telescopic frame assembly 210.
[0103] The third telescopic frame assembly 250 is sleeved in the second telescopic frame assembly 230. First, remove the additional plate 266, and then the third telescopic frame assembly 250 is integrally sleeved vertically upward. When the bottom of the third upper frame 251 is stacked on the second limiting plate 241, the sleeving of the third telescopic frame assembly 250 is completed. The second limiting plate 241 provides a vertically upward supporting force to the third telescopic frame assembly 250 through the third upper frame 251. During the above sleeving process, the second rollers 263 of the third telescopic frame assembly 250 rollingly contact the inner sides of the second guiding columns 233 of the second telescopic frame assembly 230.
[0104] When the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are sleeved in sequence, reinstall the removed mounting plate 224 and additional plate 266 in place respectively.
[0105] The first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are sleeved in sequence and vertically extended to the maximum length. There is a clearance fit relationship between them in the horizontal direction to form a relatively enclosed aquaculture space. Aquatic organisms are cultured in the telescopic aquaculture tank 200 in which the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are nested and connected to each other and vertically extended to the maximum length.
[0106] Furthermore, when transferring the aquatic organisms from the telescopic aquaculture tank 200 to the built-in ship's cabin, catching, or transferring to other facilities, the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are vertically folded to the minimum length, and the horizontal axial centers of the first valve 222, the second valve 237, and the third valve 260 are all on the same straight line. Open the first valve 222, the second valve 237, and the third valve 260 in sequence to form a transfer channel for aquatic organisms that is communicated inside and outside the telescopic aquaculture tank 200, as Figure 17 and Figure 19 shown.
[0107] Further, during the folding and telescoping process of the above-mentioned collapsible aquaculture bin 200, driven by the winch 105, the third telescopic frame assembly 250 is jointly pulled and lifted by the first suspension chain 106 and the second suspension chain 256. The additional plate 266 on the third upper frame 251 first contacts the second lower frame 232 of the second telescopic frame assembly 230 during the upward movement. Since the outer edge of the additional plate 266 is located outside the third upper frame 251, when the additional plate 266 rises with the third telescopic frame assembly 250, it can push the second lower frame 232 to rise, thereby jacking up the second telescopic frame assembly 230.
[0108] During the above-mentioned folding process, the bottom net plate 255 of the third telescopic frame assembly 250 acts as a fish driving device inside the collapsible aquaculture bin 200. Aquatic organisms 280 will be forced to concentrate in the first telescopic frame assembly 210 as the vertical length of the collapsible aquaculture bin 200 shortens. When the first valve 222, the second valve 237, and the third valve 260 are opened, the aquatic organisms can be transferred to the built-in cabin of the aquaculture workboat 100 through the fish inlet and outlet 104. The entire fish driving process does not use mechanical devices such as fish suction pumps, so the impact on the aquatic organisms 280 is small and it provides strong protection.
[0109] Based on the above-mentioned folding process, when the aquaculture workboat 100 is sailing, the above-mentioned collapsible aquaculture bin 200 needs to be locked accordingly to prevent slipping and loss. Specifically,
[0110] First, the first locking pin 242 and the second locking pin 265 are respectively passed through the second hole 217 and fixed. The rotating plate 218 is rotated around the hinge point with the first pin shaft 216, and the first groove 219 is respectively inserted into the first locking pin 242 and the second locking pin 265.
[0111] Second, the first pin 226 is inserted into the chain hole 257 of the second suspension chain 256 to assist in maintaining the vertical stability of the second suspension chain 256 for lifting the bottom net plate 255 (including jacking up the second telescopic frame assembly 230 through the third telescopic frame assembly 250), improving the safety factor of the collapsible aquaculture bin 200 in the fully folded state, and the ability to resist wind and wave shaking.
[0112] Then, the mounting plate 224 connecting the first upper frame 211 is disassembled, that is, the bolt passing through and fastening the first hole 212, the fourth hole 225, and the first screw hole 103 is disassembled. The winch 105 is continued to be started to lift the folded telescopic aquaculture net cage 200 as a whole above the fixing frame 101.
[0113] Finally, as Figure 26 shown at T in the figure, the limiting block 110 is converted from the vertical state to the horizontal state. The winch 105 is reversed to place the telescopic aquaculture net cage 200 as a whole on the limiting block 110, and the telescopic aquaculture net cage 200 is locked to the fixing frame 101 and the lifting frame 102 through ship cables.
[0114] Example 2, as Figures 27 to 29 shown, the telescopic aquaculture bin 200 carried on the aquaculture workboat 100 includes a first telescopic frame assembly 210, a second telescopic frame assembly 230, and a third telescopic frame assembly 250 that are nested and connected to each other vertically;
[0115] The difference from Example 1 is that a second channel plate 235 with a through connection is not provided on the second net plate 234 of the second telescopic frame assembly 230, and a third channel plate 258 with a through connection is not provided on the third net plate 254 of the third telescopic frame assembly 250. That is, only the first channel plate 220 and the first valve 222 for water organisms to enter and exit are provided on the first net plate 215 of the first telescopic frame assembly 210;
[0116] A fishing net assembly 300 is provided inside the telescopic aquaculture bin 200. The fishing net assembly 300 includes a fishing net 301 and a crossbar 302 for hanging the fishing net 301. Several groups of crossbars 302 are tied together by the same pulling rope 303. The free end of the pulling rope 303 is fixedly connected to the pulling rope hole 304 on the mounting plate 224. The bottom of the fishing net 301 of the fishing net assembly 300 covers the bottom net plate 255 of the third telescopic frame assembly 250;
[0117] When the telescopic aquaculture bin 200 is folded vertically, with the upward movement of the third telescopic frame assembly 250, the fishing net assembly 300 automatically folds up;
[0118] The first valve 222 can also be opened, and the operator manually pulls the pulling rope 303 to direct the aquatic organisms 280 to the built-in cabin of the aquaculture workboat 100.
[0119] Other structural designs and aquaculture methods are the same as those in Example 1.
[0120] Example 3, as Figures 30 to 33 shown, the telescopic aquaculture bin 200 carried on the aquaculture workboat 100 includes a first telescopic frame assembly 210, a second telescopic frame assembly 230, and a third telescopic frame assembly 250 that are nested and connected to each other vertically;
[0121] The differences from Example 1 and Example 2 are that an air-floating net assembly 400 is provided inside the third telescopic frame assembly 250. The air-floating net assembly 400 has an air-floating frame 401. Several air bags 404 and a bottom net 402 are respectively provided at the bottom of the air-floating frame 401. Several groups of air pipes 403 connecting to an external inflation device communicate with the air bags 404. The top ends of the air pipes 403 are retractably suspended at the pulling rope holes 304 on the mounting plate 224;
[0122] When sufficient compressed air is filled into the airbag 404 through the air pipe 403, the buoyancy force received by the air floating frame 401 continuously increases and it can float vertically upward as a whole; when the compressed air in the airbag 404 is pumped out through the air pipe 403, the air floating frame 401 of the air floating net assembly 400 coincides with the bottom net plate 255 of the third telescopic frame assembly 250 under the action of gravity, and the air pipe 403 can be temporarily fixed and suspended at the rope pulling hole 304.
[0123] Furthermore, a brush 405 is arranged on the side of the air floating frame 401. When the air floating frame 401 reciprocates vertically up and down along the inner cavity of the telescopic aquaculture tank 200, the brush 405 can be used to clean the inner wall surface of the telescopic frame assembly to prevent the attachment and growth of parasites such as barnacles.
[0124] Adopt the same folding method of the telescopic aquaculture tank 200 as in Embodiment 1, and the air floating net assembly 400 is lifted together with the third telescopic frame assembly 250; continuously fill compressed air into the airbag 404, and the air floating frame 401 detaches from the bottom net plate 255 and floats vertically upward until all the aquatic organisms 280 are driven out of the telescopic aquaculture tank 200 through the first valve 222, such as being transferred to the aquaculture workboat 100.
[0125] During the process of folding the telescopic aquaculture tank 200 and using the air floating net assembly 400 to drive the aquatic organisms 280, the brush 405 lifted together with the air floating frame 401 contacts the inner walls of the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 respectively. Relying on the elasticity of the brush 405, it can prevent the aquatic organisms 280 from escaping from the gaps, and the directional driving effect is better.
