Description

Technical Field

[0001] The present invention relates to a new method for implementing aquaculture in open waters by using a retractable aquaculture bin in the internal space, belonging to the technical field of aquaculture. Background Art

[0002] At present, the existing flowing water aquaculture and recirculating water aquaculture technologies have been widely applied in the field of aquaculture. Based on the aquaculture containers, feed feeding, and water treatment equipment in a specific space, the aquaculture water environment can be improved accordingly, the aquaculture density of the water body can be increased, and ultimately a higher growth rate and yield can be obtained.

[0003] As described in the following prior publicly disclosed Chinese patent application, with the application number 2021106894099 and the name of fully mobile three-dimensional aquatic organism aquaculture system, a submersion three-dimensional device and control method suitable for the aquaculture of various aquatic organisms are proposed. Through the design and use of several modular and mobile small aquaculture containers arranged in a queue, during the sequential movement of all aquaculture 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 aquaculture cycle of aquatic organisms, and accordingly improve the yield of aquaculture organisms per unit area and the water body utilization rate, so as to solve the mechanization and automation technical problems of feeding, catching, sorting, and cleaning in the submersion multi-layer aquaculture mode. The fully mobile three-dimensional aquatic organism aquaculture system includes an outer frame assembly, several small aquaculture 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 prior art still adopts a closed aquaculture mode inside the ship's cabin. The aquaculture space is limited by the load of the workboat itself, the aquaculture density of a single bin 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 aquaculture workboat. With the continuous development of large-scale deep-sea aquaculture facilities, especially the technology of large aquaculture workboats, how to optimize the utilization rate of aquaculture space, increase the aquaculture water volume of a single workboat, and improve the automation aquaculture efficiency has become particularly prominent.

[0005] In view of this, this patent application is specifically proposed. Summary of the Invention

[0006] The open water aquaculture method described in the present invention aims to solve the problems existing in the above-mentioned prior art and proposes a new aquaculture mode with an open net cage structure arranged outside the workboat. Through the design of a telescopic bin structure, the characteristics of easy loading and transportation during transfer and transportation are realized. At the same time, the natural water environment is fully utilized for aquaculture to meet the design purposes of improving aquaculture efficiency, reducing the structural difficulty and energy consumption of the workboat.

[0007] To achieve the above design objectives, the disclosed open-water aquaculture method is to implement full-cycle aquaculture management from fry to catch in a telescopic aquaculture tank including at least two sets of telescopic frame components nested and connected in sequence; when the aquaculture workboat is sailing, transfer the aquatic organisms cultured in the telescopic aquaculture tank to the built-in cabin for temporary cultivation, and fully fold all the telescopic frame components along the axial center; when the aquaculture workboat is stationary, fully extend all the telescopic frame components along the axial center; culture aquatic organisms in the telescopic aquaculture tank on one or both sides outside the hull, and when culturing, place the telescopic aquaculture tank in the open-water environment outside the workboat.

[0008] Furthermore, fix the telescopic aquaculture tank on the outer side of the hull of the aquaculture workboat through a fixing frame; fix a lifting frame above the fixing frame vertically, and vertically lift or retract the telescopic aquaculture tank through the first lifting chain driven by a winch; after lifting the telescopic aquaculture tank, place it on the limiting block in a horizontal state on the fixing frame, and the telescopic aquaculture tank is integrally placed on the fixing frame.

[0009] Furthermore, the telescopic aquaculture tank includes a first telescopic frame component, a second telescopic frame component, and a third telescopic frame component nested and connected with each other along the vertical center; put the second telescopic frame component into the first telescopic frame component, first remove the mounting plate, and then integrally put the second telescopic frame component into the first telescopic frame component vertically upward. When the bottom of the second upper frame is stacked on the first limiting plate, the installation of the second telescopic frame component is completed; during the installation process, the first roller of the second telescopic frame component rolls and contacts the inner side of the first guiding column of the first telescopic frame component; put the third telescopic frame component into the second telescopic frame component, first remove the additional plate, and then integrally put the third telescopic frame component into it vertically upward. When the bottom of the third upper frame is stacked on the second limiting plate, the installation of the third telescopic frame component is completed; during the installation process, the second roller of the third telescopic frame component rolls and contacts the inner side of the second guiding column of the second telescopic frame component; when the installation of the first telescopic frame component, the second telescopic frame component, and the third telescopic frame component is completed in sequence, install the mounting plate and the additional plate in place respectively.

[0010] Furthermore, when the first telescopic frame component, the second telescopic frame component, and the third telescopic frame component are sequentially sleeved and extended to the maximum length along the axis, there is a clearance fit between them along the axis and a relatively enclosed aquaculture space is formed.

[0011] Furthermore, when transferring the aquatic organisms out of the telescopic aquaculture tank, the first telescopic frame component, the second telescopic frame component, and the third telescopic frame component are folded to the minimum length vertically, and all the valves with the horizontal axial centers on the same straight line are opened to form a transfer channel for aquatic organisms that communicates inside and outside the telescopic aquaculture tank.

[0012] Further, during the process of folding and retracting the telescopic aquaculture bin, the third telescopic frame assembly is lifted by the hanging chain, and the second lower frame is pushed to lift by the additional plate on the third upper frame to jack up the second telescopic frame assembly; the aquatic organisms are concentrated in the first telescopic frame assembly as the vertical length of the telescopic aquaculture bin shortens; when all the valves are opened, the aquatic organisms are transferred to the built-in cabin of the aquaculture workboat through the fish inlet and outlet.

[0013] Further, when the aquaculture workboat is sailing, the telescopic aquaculture bin is locked; first, the first locking pin and the second locking pin are respectively passed through the second hole and fixed, and the rotating plate is rotated around the hinge point with the first pin shaft 216, and the first grooves are respectively embedded into the first locking pin and the second locking pin;

[0014] Secondly, the first pin is inserted into the chain hole of the second hanging chain to assist in maintaining the stability of the second hanging chain in the vertical direction; then, the mounting plate connecting the first upper frame is disassembled, and the winch is continued to be started to lift the folded telescopic aquaculture net cage as a whole to above the fixing frame; finally, the limiting block is changed from the vertical state to the horizontal state, and the winch is reversed to place the telescopic aquaculture net cage as a whole on the limiting block, and the telescopic aquaculture net cage is locked with the fixing frame and the lifting frame through the ship cable.

[0015] Further, a fishing net assembly is arranged inside the telescopic aquaculture bin. When the telescopic aquaculture bin is folded vertically, the fishing net assembly is automatically folded along with the upward movement of the third telescopic frame assembly;

[0016] Further, an air-floating net assembly is arranged inside the third telescopic frame assembly. The air-floating net assembly has an air-floating frame, and several air bags and a bottom net are respectively arranged at the bottom of the air-floating frame. A plurality of air pipes connecting an external inflation device are communicated with the air bags; when the telescopic aquaculture bin is folded vertically, the air bags are inflated, and the air-floating frame floats vertically to drive the aquatic organisms until all the aquatic organisms are driven out of the telescopic aquaculture bin through the valve.

[0017] Further, brushes are arranged on the peripheral sides of the air-floating frame. During the process of using the air-floating net assembly to drive the aquatic organisms, the brushes that are lifted along with the air-floating frame respectively contact the inner walls of the telescopic frame assembly to clean the attached substances and prevent the aquatic organisms from escaping from the gaps by relying on the elastic force of the brushes.

[0018] In summary, the open-water aquaculture method described in this application has the following advantages:

[0019] 1. This application proposes improvements and optimizations for the immersion-type three-dimensional aquaculture of various types of aquatic organisms. The proposed telescopic aquaculture bin can be applied to various aquaculture workboats and deep-sea platform aquaculture systems in a modular and standardized embedded structure, with high aquaculture efficiency and conforming to the industrialized and precise aquaculture mode.

[0020] 2. The aquaculture bin proposed in this application adopts a retractable frame net cage structure. Based on the open aquaculture mode, during the transfer and transportation processes, the aquaculture bin is in a contracted state, and the aquaculture aquatic organisms are temporarily transported by the ship's cabin. Therefore, the aquaculture workboat applying such a retractable aquaculture bin does not need to be too large, and its structural design is relatively simple, effectively reducing the shipbuilding cost.

[0021] 3. Applying this application, based on the open net cage structure set outside the workboat and using the natural water environment for aquaculture, not only reduces the high technical requirements for the hull structure and internal management system of the deep-sea workboat, but also saves many problems such as regular cleaning and energy consumption caused by the internal cabin water circulation during the aquaculture process. The aquaculture efficiency is relatively high and the operation cost is relatively low.

[0022] 4. Applying the retractable aquaculture bin proposed in this application can ensure the directional movement of the aquaculture aquatic organisms and they are not easily damaged or escape through the gaps during the processes of the aquaculture aquatic organisms entering and leaving, being caught, etc. It is beneficial to realize the transfer between the aquaculture net cage and the aquaculture workboat or other transport ships, improve the adaptability and survival comfort of the aquaculture aquatic organisms, and effectively increase the aquaculture output.

[0023] 5. The retractable aquaculture bin proposed in this application belongs to a modular design scheme, which is beneficial to transplantation on various types of aquaculture workboats and series-parallel layout of multiple groups of bins. It is beneficial to improve the stability and wave resistance performance during the mooring or operation of the workboat, and is also easy to overhaul and maintain.

[0059] The disclosed open - water aquaculture method of the present application applies a new type of telescopic aquaculture tank, in which the whole - cycle aquaculture from fry to catch, automated sorting and catching operations can be realized, thus achieving dynamic and refined aquaculture management.

[0060] Embodiment 1, as Figures 1 to 26 shown, the aquaculture ship 100 carrying the telescopic aquaculture tank 200 includes an internal cabin, and the cabin can be used to temporarily raise 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 ship 100, and the telescopic aquaculture tanks 200 are placed in the open - water environment outside the ship for aquaculture and management.

[0061] Specifically, a fixed array of horizontally distributed fixing frames 101 are installed and fixed on the outer side of the hull of the aquaculture workboat 100, and a set of lifting frames 102 are fixed vertically above each set of fixing frames 101;

[0062] An inlet / outlet fish port 104 communicating with the internal cabin is provided 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 cultured in the internal cabin can be transferred to the telescopic aquaculture tank 200 located in the external open water area;

[0063] 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; Driven by the winch 105, the telescopic aquaculture tank 200 can be vertically lifted or retracted through the first lifting chain 106;

[0064] A number of limit blocks 110 are hinged to the side of the fixing frame 101 through a fixedly connected limit block support plate 107, and the limit block 100 can rotate vertically around the hinge point with the limit block support plate 107; Specifically, the limit block support plate 107 has a horizontally axially penetrating limit hole 108, and both ends of a limit shaft 109 are hinged to the limit holes 108 on both sides, and the middle of the limit shaft 109 is fixedly connected to the limit block 110.

[0065] In this embodiment, the method of driving the vertical rotation of the limit block 110 can be arbitrarily selected based on the prior art, such as adopting a transmission method of driving the limit shaft 109 by a cylinder or a servo motor; When the output shaft of the cylinder or the servo motor drives the limit shaft 109 to rotate around a fixed axis, driven by the limit shaft 109, the limit block 110 rotates around the axial center of the limit shaft 109, thereby changing its own positioning angle relative to the fixing frame 101; When the limit block 110 rotates vertically to the vertical state, the process of the winch 105 vertically lifting or retracting the telescopic aquaculture tank 200 is not hindered by any means; When the limit block 110 rotates to the horizontal state (as Figure 26 shown), the telescopic aquaculture tank 200 can be integrally erected on the limit block 110, and the limit block 110 plays an upward supporting role, and assists in realizing the vertical positioning of the telescopic aquaculture tank 200 without slipping;

[0066] A mooring ring 111 is fixedly connected to the side of the fixing frame 101 away from the aquaculture workboat 100. Through this mooring ring 111, other adjacent parked vessels can be moored with a cable.

[0067] The 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;

[0068] Among them, the first telescopic frame assembly 210 has a first upper frame 211 and a first lower frame 213. An array of first guide columns 214 are connected between the vertical directions of the first upper frame 211 and the first lower frame 213. A first mesh plate 215 is connected between two adjacent groups of first guide columns 214.

[0069] A first trough plate 220 is connected through the first mesh plate 215 in a penetrating manner. The first trough plate 220 is docked with the fish inlet / outlet 104 to form a transfer interface channel between the telescopic breeding tank 200 and the breeding workboat 100. A group of first sliding grooves 221 are respectively arranged on both sides of the first trough plate 220. The first valve 222 is hinged to the first trough plate 220 and reciprocates along the first sliding groove 221 to open or close the through hole on the first mesh plate 215.

[0070] A first hole 212 is arranged vertically on the first upper frame 211.

[0071] An array of vertically connected first limiting plates 227 are arranged on the first lower frame 213.

[0072] 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 arranged at the end corners of the mounting plate 224. A third hole 223 is arranged at the center of the mounting plate 224. A fourth hole 225 is arranged on the side of the mounting plate 224.

[0073] One end of the rotating plate 218 is hinged to the first pin shaft 216 through the rotating plate hole 228. Several first grooves 219 are arranged on the side of the rotating plate 218.

[0074] A first pin 226 is arranged on the mounting plate 224 adjacent to the third hole 223. 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. For example, a transmission method of using a cylinder or a servo motor to drive the first pin 226 for linear motion will not be elaborated here.

[0075] 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.

[0076] A first screw hole 103 is arranged on the fixing frame 101. The first upper frame 211 and the mounting plate 224 can be sequentially installed and fixed on the fixing frame 101 by bolts respectively passing through the first screw hole 103, the first hole 212, and the fourth hole 225, thereby realizing the connection between the first telescopic frame assembly 210 and the breeding workboat 100.

[0077] The described second telescopic frame assembly 230 has a second upper frame 231 and a second lower frame 232. An array of second guide posts 233 are connected vertically between the second upper frame 231 and the second lower frame 232. A second net plate 234 is connected between two adjacent sets of second guide posts 233;

[0078] A second channel plate 235 is connected through the second net plate 234. A second limiting plate 241 is fixedly connected to the second lower frame 232;

[0079] A set of second sliding grooves 236 are respectively arranged on both sides of the second channel plate 235. The second valve 237 is vertically arranged through a first notch 238 on the second upper frame 231. Both sides of the second valve 237 are slidably connected to the second sliding grooves 236;

[0080] First locking pins 242 are respectively fixedly connected to the end corners of the second upper frame 231;

[0081] An array of first roller brackets 243 are fixedly connected to the second guide posts 233. The first roller 240 is hinged to the first roller bracket 243 through a second pin shaft 239 and rotates around its axis;

[0082] When the second telescopic frame assembly 230 is sleeved in the first telescopic frame assembly 210, first remove the mounting plate 224, and then integrally sleeve the second telescopic frame assembly 230 vertically upward into the first telescopic frame assembly 210. 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. The first limiting plate 227 provides a vertically upward supporting force to the second telescopic frame assembly 230 through the second upper frame 231;

[0083] 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.

[0084] The described third telescopic frame assembly 250 has a third upper frame 251 and a third lower frame 252. An array of third guide posts 253 are connected vertically between the third upper frame 251 and the third lower frame 252. A third net plate 254 is connected between two adjacent sets of third guide posts 253. A bottom net plate 255 is fixedly connected to the bottom of the third lower frame 252;

[0085] A third channel plate 258 is connected through the third net plate 254. A set of third sliding grooves 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 sliding grooves 259 and can slide vertically back and forth;

[0086] 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 respective 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;

[0087] Second locking pins 265 are fixedly connected to the respective end corners of the third upper frame 251;

[0088] An array of second roller brackets 262 is fixedly connected to the top end of the third guide post 253. The second roller 263 is hinged to the second roller bracket 262 through a third pin shaft 263 and rotates around its axial direction;

[0089] 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 sequentially passing bolts through the fifth hole 267 and the sixth hole 268; 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;

[0090] 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;

[0091] When the third telescopic frame assembly 250 is sleeved on 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 supports 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;

[0092] 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 and contacts the inner side of the second guide post 233 of the second telescopic frame assembly 230;

[0093] 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.

[0094] As described in 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, a stable vertical positioning is formed between the third telescopic frame assembly 250 and the second telescopic frame assembly 230 under the support of the second limiting plate 241, and the two remain relatively stationary; under the support 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 the fixed frame 101, and finally the overall fixed connection between the telescopic aquaculture bin 200 and the fixed frame 101 is realized.

[0095] Further, to prevent the cultured aquatic organisms from escaping between the components constituting the above-mentioned telescopic aquaculture bin 200, when the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are sleeved in sequence 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 sleeved in place in sequence, a clearance fit relationship is formed between them in the horizontal direction to form a relatively enclosed aquaculture space;

[0096] Further, to optimize the transfer operation of the cultured aquatic organisms into the internal cabin of the aquaculture workboat 100, or when it is necessary to transfer the cultured aquatic organisms out of the telescopic aquaculture bin when encountering unknown risks, when the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are sleeved in sequence 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.

[0097] Based on the above-mentioned telescopic aquaculture bin 200, the open-water aquaculture method proposed in this application is as follows:

[0098] Apply the telescopic aquaculture bin 200 to the aquaculture workboat 100 or the deep-sea and far-sea aquaculture platform, and implement the full-cycle aquaculture management from fry to catch in the telescopic aquaculture bin 200;

[0099] Specifically, when the aquaculture workboat 100 is sailing, transfer the aquatic organisms cultured in the telescopic aquaculture bin 200 to the internal cabin for temporary cultivation; when the aquaculture workboat 100 is stationary, culture the aquatic organisms in the telescopic aquaculture bin 200 on one or both sides outside its hull, and when culturing, place the telescopic aquaculture bin 200 in the open-water environment outside the workboat.

[0100] The telescopic aquaculture tank 200 is fixed to the outer side of the hull of the aquaculture workboat 100 through the fixing frame 101. Specifically, a hoisting frame 102 is fixed above the fixing frame 101 in the vertical direction. Driven by the winch 105, the telescopic aquaculture tank 200 can be vertically hoisted or retracted through the first lifting chain 106;

[0101] After hoisting the telescopic aquaculture tank 200, it is placed on the limiting block 110 in the horizontal state on the fixing frame 101, and the telescopic aquaculture tank 200 is integrally placed on the fixing frame 101.

[0102] Furthermore, the 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 to each other along the vertical center;

[0103] 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 in the vertical upward direction. 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, and 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 roller 240 of the second telescopic frame assembly 230 rolls and contacts the inner side of the first guiding column 214 of the first telescopic frame assembly 210;

[0104] The third telescopic frame assembly 250 is sleeved in the second telescopic frame assembly 230. First, the additional plate 266 is removed, and then the third telescopic frame assembly 250 is integrally sleeved in the vertical upward direction. 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, 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; during the above sleeving process, the second roller 263 of the third telescopic frame assembly 250 rolls and contacts the inner side of the second guiding column 233 of the second telescopic frame assembly 230;

[0105] When the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are sequentially sleeved and completed, the removed mounting plate 224 and additional plate 266 are respectively reinstalled in place;

[0106] The first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are sequentially sleeved and extended to the maximum length in the vertical direction, and a clearance fit relationship is formed 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 extended to the maximum length in the vertical direction.

[0107] Furthermore, when transferring aquatic organisms from the telescopic breeding warehouse 200 to the built-in cabin, catching, or transporting them to other facilities, the first telescopic frame assembly 210, the second telescopic frame assembly 230, and the third telescopic frame assembly 250 are folded vertically 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; the first valve 222, the second valve 237, and the third valve 260 are opened in sequence to form an aquatic organism transfer channel connecting the inside and outside of the telescopic breeding warehouse 200, such as Figure 17 and Figure 19 shown.

[0108] Furthermore, during the folding of the telescopic breeding warehouse 200, the first lifting chain 106 and the second lifting chain 256 jointly pull and lift the third telescopic frame assembly 250 under the drive of the winch 105, and 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 together with the third telescopic frame assembly 250, the second lower frame 232 can be pushed to rise, thereby lifting the second telescopic frame assembly 230;

[0109] During the above-mentioned folding process, the bottom mesh plate 255 of the third telescopic frame assembly 250 is equivalent to the fish-driving device inside the telescopic breeding warehouse 200. The aquatic organisms 280 will be forced to concentrate in the first telescopic frame assembly 210 as the vertical length of the telescopic breeding warehouse 200 is shortened; 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 breeding ship 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 effective protection is implemented.

[0110] Based on the above folding process, when the aquaculture vessel 100 is sailing, the telescopic aquaculture bin 200 needs to be locked accordingly to prevent it from slipping and being lost; specifically,

[0111] First, the first locking pin 242 and the second locking pin 265 are respectively passed through the second hole 217 and fixed, and the rotating plate 218 is rotated around the hinge point with the first pin shaft 216, and the first groove 219 is respectively embedded in the first locking pin 242 and the second locking pin 265;

[0112] Secondly, the first pin 226 is inserted into the lifting chain hole 257 of the second lifting chain 256 to assist in maintaining the vertical stability of the second lifting chain 256 for lifting the bottom mesh plate 255 (including lifting the second telescopic frame assembly 230 through the third telescopic frame assembly 250), and improving the safety factor of the telescopic breeding warehouse 200 in a fully folded state and the ability to resist shaking and bumping due to wind and waves;

[0113] Then, disassemble the mounting plate 224 connected to the first upper frame 211, that is, disassemble the bolts passing through and fastening the first hole 212, the fourth hole 225 and the first screw hole 103, and continue to start the winch 105 to move the folded telescopic aquaculture cage 200 upward as a whole to above the fixing frame 101;

[0114] Finally, as shown at T in Figure 26 , convert the limiting block 110 from the vertical state to the horizontal state, reverse the winch 105 to place the telescopic aquaculture cage 200 as a whole on the limiting block 110, and lock the telescopic aquaculture cage 200 to the fixing frame 101 and the lifting frame 102 through the ship cable.

[0115] Example 2, as shown in Figures 27 to 29 , 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;

[0116] The difference from Example 1 is that the second channel-shaped plate 235 with a through connection is not provided on the second net plate 234 of the second telescopic frame assembly 230, and the third channel-shaped 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-shaped 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;

[0117] A fishing net assembly 300 is arranged inside the telescopic aquaculture bin 200. The fishing net assembly 300 includes a fishing net 301 and a cross rope 302 for hanging the fishing net 301. Several cross ropes 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;

[0118] When the telescopic aquaculture bin 200 is folded vertically, along with the upward movement of the third telescopic frame assembly 250, the fishing net assembly 300 automatically folds up;

[0119] The first valve 222 can also be opened, and the operator manually pulls the pulling rope 303 to direct and drive the aquatic organisms 280 into the built-in cabin of the aquaculture workboat 100.

[0120] Other structural designs and aquaculture methods are the same as those in Example 1.

[0121] Example 3, as shown in Figures 30 to 33As shown in the figure, the telescopic aquaculture tank 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.

[0122] Different from Embodiment 1 and Embodiment 2, an air-floating net assembly 400 is arranged 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 arranged at the bottom of the air-floating frame 401. A plurality of air pipes 403 connecting to an external inflation device communicate with the air bags 404, and the top ends of the air pipes 403 are retractably suspended in the rope holes 304 on the mounting plate 224.

[0123] When sufficient compressed air is filled into the air bags 404 through the air pipes 403, the buoyancy received by the air-floating frame 401 continuously increases and it can float vertically as a whole. When the compressed air in the air bags 404 is pumped out through the air pipes 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 pipes 403 can be temporarily fixed and suspended in the rope holes 304.

[0124] Furthermore, a brush 405 is arranged on the side of the air-floating frame 401. When the air-floating frame 401 reciprocates vertically in 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.

[0125] Adopting the same folding method of the telescopic aquaculture tank 200 as in Embodiment 1, the air-floating net assembly 400 is lifted together with the third telescopic frame assembly 250; continuously fill compressed air into the air bags 404, 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.

[0126] 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.

[0127] In summary, the embodiments given in the accompanying drawings are only the preferred solutions to achieve the purpose of the present invention. For those skilled in the art, they can get inspiration from this and directly derive other alternative structures that conform to the design concept of the present invention. The other structural features obtained thereby should also fall within the scope of the solutions described in the present invention.
