Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, and in particular to a marine wind-fish integrated feed self-sufficient aquaculture cage and aquaculture method. Background Technology

[0002] Offshore wind power is a clean energy source. Compared to nearshore wind power, offshore wind power has higher quality and more stable wind resources, a larger exploitable area, and less impact on the human living environment, making it more suitable for developing large-scale wind farms. To improve the utilization of large-scale offshore wind farms, people are integrating offshore power generation with mariculture, which can achieve simultaneous and efficient production of clean energy and marine aquaculture, significantly improving the efficiency of marine resource utilization. For example, patent application CN120240371A discloses an aquaculture cage for offshore wind power foundation and its working method, as well as an offshore wind power jacket. By directly configuring the aquaculture cage on the jacket foundation, it achieves the spatial composite utilization of offshore wind power facilities and aquaculture functions, while facilitating the deployment and retrieval of the aquaculture netting. The structure is also relatively stable after installation. However, its drawbacks are that feeding the aquatic products in the cages is inconvenient (they easily disperse into the seawater), and it is impossible to observe the status of the aquatic products in the cages in real time. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a marine wind-fish integrated bait self-sufficient aquaculture cage and aquaculture method, which can attract small fish and shrimp in the sea area as bait for aquaculture and allow real-time observation of the aquaculture status in the cage.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This invention provides a marine wind-fish integrated self-sufficient aquaculture cage, comprising a cage body installed on a wind turbine support foundation. The cage body includes a bait trap cage and an aquaculture net arranged vertically downwards along the coastal plane. The top and bottom of the aquaculture net are connected and fixed to the guide frame of the wind turbine support foundation along the circumference of the foundation by several connecting ropes, so as to open the aquaculture net to form an aquaculture chamber. Lifting units for controlling the depth of the bait trap cage are provided on both sides of the bait trap cage on the wind turbine support foundation. A fish-attracting monitoring unit is also provided on the top of the bait trap cage, including a fish-attracting light and a monitoring lens. An acoustic repellent device that cooperates with the fish-attracting monitoring unit is also provided on the top of the bait trap cage.

[0006] The bait trap cage includes a cylindrical cage composed of several cavity trusses. The cylindrical cage is externally covered with a net to form a bait trap cavity. A feeding frame is provided in the middle of the bait trap cavity. The bait trap cage has several feeding channels along its circumference that cooperate with the feeding frame. The cross-sectional area of ​​the feeding channel in the direction perpendicular to the sea level gradually decreases from the side wall of the bait trap cage to the feeding frame. That is, the cavity truss includes several channel frames and several top frames. One end of the channel frame is fixedly connected to the feeding frame, and the other end is fixedly connected to the top frame. Four adjacent channel frames on the side wall of the feeding frame form the feeding channel. The feeding channel is truncate. The feeding frame is provided with a feeding inlet that cooperates with the feeding channel. The bait trap cavity is connected to seawater through the feeding inlet. The bait trap cage and the aquaculture net are connected through a guide unit.

[0007] To expand the space of the bait trap cavity, the cavity truss also includes several extension frames fixed to one end of the channel frame near the top frame. The other end of the extension frame is fixedly connected to the top frame, and the axial direction of the extension frame is parallel to the axial direction of the bait trap cavity.

[0008] To guide and control the feeding process of aquatic organisms, the guiding unit includes a guide cylinder whose axis is parallel to the axis of the feed trap cavity. The top of the guide cylinder is fixedly connected to the bottom of the feed trap cage, and the bottom of the guide cylinder is fixedly connected to the top of the aquaculture net. The feed trap cavity is connected to the aquaculture cavity through the guide cylinder. A flexible directional cover net is also fixed inside the guide cylinder. A guide opening is provided in the middle of the directional cover net. A guide wheel is fixedly provided at the bottom of the guide cylinder. A directional motor is provided on the top of the platform of the wind power support foundation. A directional rope is provided at the power output end of the directional motor. One end of the directional rope is connected to the side of the guide opening near the feed trap cavity, and the other end passes through the guide wheel and is connected to the side of the guide opening near the aquaculture cavity. During the non-feeding stage, the directional cover net is frustoconical, and the guide opening is close to the aquaculture cavity.

[0009] The lifting unit includes a lifting motor installed on the top of the wind turbine support foundation platform. A lifting wheel is installed on the guide frame of the wind turbine support foundation near the bottom of the bait trap cage. A lifting rope is installed at the power output end of the lifting motor. One end of the lifting rope is connected to the top of the bait trap cage, and the other end passes through the lifting wheel and is connected to the bottom of the bait trap cage.

[0010] To allow for flexible adjustment of the size of the feeding inlet, the feeding frame is also equipped with a feeding plate that cooperates with the feeding inlet. The feeding frame has a feeding groove that cooperates with the feeding plate. The feeding plate and the feeding groove are connected by insertion. The feeding plate has a feeding hole, and a feeding net is fixed in the feeding hole. The top of the feeding plate is detachably connected to the top of the feeding frame.

[0011] A method for self-sufficient marine aquaculture using a combined wind-fishing and bait system, comprising the following steps:

[0012] S00: Fish attraction stage, turn on the fish attraction light to attract bait creatures into the bait trap cavity through the bait inlet channel, and use the monitoring camera to observe the number of bait creatures in the bait trap cavity in real time;

[0013] S10: During the feeding stage, when the number of food organisms in the bait trap cavity reaches the feeding limit as monitored by the monitoring lens, the directional motor is started, and the directional rope is used to pull the guide opening from near the breeding cavity to near the bait trap cavity. At this time, the organisms in the breeding cavity enter the bait trap cavity from the guide opening to feed.

[0014] S20: Fish driving stage. When the monitoring lens detects that the cultured organisms in the bait trap cavity have finished feeding, the reversing motor is started in the opposite direction. The reversing rope is used to pull the guide port from near the bait trap cavity to near the culture cavity. The fish attractant light is turned off, and the sonic repellent is started to drive the cultured organisms in the culture cavity from the guide port into the culture cavity.

[0015] S30: Turn on the fish-attracting light, turn off the sonic repellent, and proceed to the next stage to attract bait creatures.

[0016] The invention also includes a self-sufficient offshore wind-fishing aquaculture cage, comprising a cage body mounted on a wind turbine support foundation. The cage body includes a bait trap cage and an aquaculture net arranged vertically downwards from the sea surface. The bait trap cage comprises a columnar cage composed of several cavity trusses. A flexible net is tied and covered to the outside of the columnar cage to form a bait trap cavity. The top and bottom of the aquaculture net are connected to the guide frame of the wind turbine support foundation along the circumference of the foundation by several connecting ropes, allowing the aquaculture net to be opened to form the aquaculture cavity. The bait trap cavity and the aquaculture cavity are connected by a guide unit. A feeding frame is provided in the middle of the bait trap cavity. The bait trap cage has several feeding channels arranged circumferentially to cooperate with the feeding frame. The cross-sectional area of ​​the feeding channels perpendicular to the sea surface gradually increases from the side wall of the bait trap cage to the feeding frame. The bait trap chamber gradually decreases in size. The bait frame is provided with a bait inlet that cooperates with the bait inlet channel. The bait trap chamber is connected to seawater through the bait inlet. The chamber truss includes several channel frames. One end of the channel frame is hinged to the bait frame, and the other end is fixedly connected to the top frame. Four adjacent channel frames on the side wall of the bait frame form the bait inlet channel, which is truncate. The top of the net of the bait trap chamber is provided with a functional grid that cooperates with the bait frame. The functional grid is provided with a fish-attracting monitoring unit and an acoustic repellent. Folding motors that control the depth of the bait trap cage are provided on both sides of the bait trap cage on the wind turbine support base. The power output end of the folding motor is provided with a folding rope. One end of the folding rope is connected to the top of the bait trap cage. The bottom of the bait trap cage is fixed to the guide frame of the wind turbine support base through a connecting rope.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) In this case, the bait collection space (bait trap cage) and the aquaculture space (aquaculture net) are vertically integrated on the wind power support base. Basically, there is no need to modify the original offshore wind power platform, and it does not affect wind power management. It realizes the efficient use of the three-dimensional space of the sea area. The bait trap cage has a platform-shaped feeding channel, which makes it easy for bait organisms to enter but difficult to exit, thus improving the collection efficiency.

[0019] (2) This case mainly uses fish-attracting lights, feeding channels and other structures to attract fish and shrimp in natural sea areas as bait, reducing or eliminating the need for artificial feeding, which can greatly improve the quality of farmed aquatic products. At the same time, the fish-attracting monitoring unit facilitates the management and remote observation of the farming process, eliminating the need for feeding (or only requiring periodic and appropriate supplementary feeding according to environmental needs).

[0020] (3) This case sets up a guide unit for communication between the bait trap chamber and the aquaculture chamber. The guide unit and the directional cover net structure enable the controlled migration of aquatic organisms between the bait area and the aquaculture area. That is, when the aquatic organisms are feeding, they enter the bait trap chamber through the directional cover net of the guide unit. After feeding, they return to the aquaculture chamber through the directional cover net of the guide unit. In addition, a foldable bait trap chamber structure and a sonic drive are added to ensure efficient guidance of the aquatic organisms' feeding process and baiting efficiency.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] In offshore wind farm aquaculture activities, to address the problems of inconvenience in feeding aquatic organisms in net cages (which easily spread into the seawater) and the inability to observe the status of aquatic organisms in the aquaculture nets in real time, this invention provides an offshore wind-fish integrated feed self-sufficient aquaculture net cage and aquaculture method.

[0042] Example 1: A self-sufficient marine aquaculture cage integrating wind and fish feeding, comprising a cage body 2 mounted on a wind turbine support foundation 1. The cage body 2 is vertically positioned in the sea area using the wind turbine support foundation 1 for aquatic organism cultivation. Compared to integrating the space for aquatic organism cultivation and the space for bait into one space, separating the two avoids the aquatic organisms occupying too much space and affecting the amount of bait attracted. The core idea of ​​this invention is to set up a space for aquatic organism cultivation and another space for attracting marine organisms such as fish and shrimp as bait, thus achieving the goal of eliminating or greatly reducing feeding. Therefore, the following is required:

[0043] a. The main body of the net cage 2 needs to efficiently attract aquatic bait;

[0044] b. Aquaculture needs to actively migrate within the aquaculture space and bait-attracting space according to its feeding status to improve the aquaculture feeding and bait-attracting efficiency of the main body of the net cage 2;

[0045] c. It is necessary to monitor the status of the aquatic organisms within the main body of the net cage 2 in real time;

[0046] Based on the above description, the main body 2 of the net cage includes a bait trap cage 21 and an aquaculture net 22 arranged vertically downwards along the coastal plane:

[0047] (1) For the bait trap cage 21: The bait trap cage 21 includes a cylindrical cage composed of several cavity trusses (in this case, a cylindrical cage with a square cross-section is used as an example). The outside of the cylindrical cage is fixedly covered with a net to form a bait trap cavity 211 (a net can be used for binding; a flexible net can be used to control the slackness of the net as needed, while a rigid net can ensure the strength of the bait trap cage 21; preferably, a rigid net can be used in this embodiment). This forms a space for attracting marine organisms such as fish and shrimp as aquaculture bait. Furthermore, in order to efficiently attract fish and shrimp in the sea area as aquaculture bait, a bait inlet frame 5 is provided in the middle of the bait trap cavity 211. The trap cage 21 has several feeding channels 212 arranged circumferentially to cooperate with the feeding frame 5, and the feeding frame 5 is provided with feeding inlets 51 to cooperate with the feeding channels 212. The bait trap cavity 211 is connected to the seawater through the feeding inlets 51. The cavity truss includes several channel frames 213 and several top frames 214. One end of the channel frame 213 is fixedly connected to the feeding frame 5, and the other end is fixedly connected to the top frame 214. Four adjacent channel frames 213 on the side wall of the feeding frame 5 form the feeding channel 212. The feeding channel 212 is truncate, that is, the cross-sectional area of ​​the feeding channel 212 in the direction perpendicular to the sea level gradually decreases along the side wall of the bait trap cage 21 to the feeding frame 5, thus reducing the overall cylindrical cage shape of the bait trap cage 21. The bait trap cage 21 is modified to resemble a funnel shape, similar to the bait inlet frame 5, with two platform-shaped frames fixed on the upper and lower sides. This allows fish and shrimp bait to enter from the wider end (larger cross-sectional area) of the bait inlet channel 212 and then enter the bait trap cavity 211 from the narrower end (smaller cross-sectional area) that cooperates with the bait inlet frame 5. This design, with a larger cross-sectional area at the inlet and a smaller cross-sectional area at the outlet, makes it difficult for fish and shrimp bait to escape from the bait trap cavity 211 after entering, thus achieving the purpose of bait accumulation in the bait trap cavity 211. To improve the bait attraction efficiency of the bait trap cavity 211, additional features can be added to the bait trap cavity 211. Some small artificial floating reefs are suspended inside, which will not be described in detail here; preferably, in order to cooperate with the feeding channel 212 to lure fish and shrimp bait into the bait trap cavity 211, the top of the bait trap cage 21 is also equipped with a fish attraction monitoring unit 4 (which can be fixed to the netting by binding, the same applies below). The fish attraction monitoring unit 4 includes a fish attraction light 41 and a monitoring lens 42. When the fish attraction light 41 is turned on, it can first lure fish and shrimp in the sea area near the wind power support foundation 1 to approach the bait trap cage 21, and then enter the bait trap cavity 211 through the feeding channel 212. At the same time, the monitoring lens 42 can be used to monitor the amount of bait in the bait trap cavity 211 to further decide whether to introduce the farmed aquatic products for feeding.

[0048] In the above structure of the bait trap cage 21, in order to further expand the volume of the bait trap cavity 211, the cavity truss also includes several extension frames 215 fixed to one end of the passage frame 213 near the top frame 214. The other end of the extension frame 215 is fixedly connected to the top frame 214, and the axial direction of the extension frame 215 is parallel to the axial direction of the bait trap cavity 211. In this way, by extending the extension frame 215, the volume of the bait trap cavity 211 can be effectively expanded in the vertical direction to ensure that a sufficient number of fish and shrimp baits can enter the bait trap cavity 211.

[0049] When fish and shrimp bait attracted in the sea area enters the bait trap chamber 211 through the feeding channel 212, it needs to pass through the feeding inlet 51 of the feeding frame 5 to enter the bait trap chamber 211. In addition, to flexibly adjust the size of the feeding inlet 51, the feeding frame 5 is also equipped with a feeding plate 52 that cooperates with the feeding inlet 51. The feeding frame 5 has a feeding groove 53 that cooperates with the feeding plate 52. The feeding plate 52 and the feeding groove 53 are connected by an insertion. The feeding plate 52 has a feeding hole 521. 21 is fixedly provided with a feeding net, and the top of the feeding plate 52 is detachably connected to the top of the feeding frame 5; thus, by inserting feeding plates 52 with different sized feeding holes 521 into the feeding groove 53, the size of the outlet end of the feeding channel 212 (i.e. the connection between the feeding channel 212 and the bait trap cavity 211) can be flexibly adjusted. At the same time, the feeding hole 521 can also use a large-mesh feeding net to further optimize the effect, and also prevent excessively large fish and shrimp from entering the bait trap cavity 211 and threatening the farmed aquatic products.

[0050] Based on the above, lifting units 3 for controlling the depth of the bait trap cage 21 are installed on both sides of the wind turbine support foundation 1. The lifting unit 3 includes a lifting motor 31 installed on the top of the platform of the wind turbine support foundation 1. A lifting wheel 32 is installed on the guide frame of the wind turbine support foundation 1 near the bottom of the bait trap cage 21. A lifting rope 33 is installed at the power output end of the lifting motor 31. One end of the lifting rope 33 is connected to the top of the bait trap cage 21, and the other end passes through the lifting wheel 32 and the bait trap cage 21. The bottom of the cage 21 is connected so that the bait trap cage 21 can be lifted by the lifting unit 3. When it is necessary to adjust the position and depth of the bait trap cage 21 or to lift it, the lifting motor 31 rotates, the length of the lifting rope 33 connected to the top of the bait trap cage 21 decreases, and the length of the section connected to the bottom of the bait trap cage 21 increases. In this way, the bait trap cage 21 can be raised, and conversely, the bait trap cage 21 can be lowered. During this process, the lifting wheel 32 can play a good guiding role and prevent the lifting rope 33 from getting tangled.

[0051] It should be noted that a power supply can also be installed on the platform of the wind turbine support foundation 1 to provide power as needed, and a communication base station can also be installed for convenient remote control. This is an easy way to achieve the above technical solutions and effects, and will not be elaborated here.

[0052] (2) For the aquaculture net 22, the top and bottom of the aquaculture net 22 are tied to the guide frame of the wind power support foundation 1 along the circumference of the wind power support foundation 1 by several connecting ropes, so that the aquaculture net 22 can be opened to form an aquaculture cavity 221. In this way, the aquatic products can be raised in the aquaculture cavity 221 of the aquaculture net 22. It should be noted that when the net cage body 2 is initially installed or removed, the aquaculture net 22 can be arranged separately or together with the bait trap cage 21 with the assistance of the lifting unit 3.

[0053] The above description of the bait trap cage 21 and the aquaculture net 22 shows that the main body 2 of the net cage constitutes a space for aquatic organism cultivation (aquaculture chamber 221) and a space for attracting marine organisms such as fish and shrimp as food for aquaculture (bait trap chamber 211). Furthermore, the fish and shrimp food in the bait trap chamber 211 and the aquaculture organisms in the aquaculture chamber 221 can be monitored in real time using the fish attraction monitoring unit 4. To facilitate the migration of aquaculture organisms within the aquaculture chamber 221 and the bait trap chamber 211, ensuring efficient feeding and bait attraction, the bait trap cage 21 and the aquaculture net 22 are connected by a guide unit 6. The guide unit 6 includes a section whose axis is aligned with the bait trap chamber 211. A guide cylinder 61, parallel to the axis, is fixedly connected at its top to the bottom of the bait trap cage 21 and at its bottom to the top of the aquaculture net 22. The bait trap cavity 211 is connected to the aquaculture cavity 221 via the guide cylinder 61. Furthermore, to achieve guidance and control of the aquatic organisms—that is, to guide them from the aquaculture cavity 221 into the bait trap cavity 211 during feeding and back from the bait trap cavity 211 to the aquaculture cavity 221 after feeding—a flexible directional cover net 62 is fixedly installed inside the guide cylinder 61. This directional cover net 62, when stretched and opened, forms a cone-shaped structure (similar to the structure of the feeding channel 212), allowing the aquatic organisms to migrate in one direction. The directional cover net 62 moves from the wider end to the narrower end. Based on this, a guide opening 621 is opened in the middle of the directional cover net 62. A guide wheel 63 is fixed at the bottom of the guide cylinder 61. This guide wheel 63 can be tied and fixed to the top of the aquaculture net 22 and cooperate with the guide opening 621. A directional motor 64 is set on the top of the platform of the wind power support foundation 1. A directional rope 65 is set at the power output end of the directional motor 64. One end of the directional rope 65 is connected to the side of the guide opening 621 near the bait trap cavity 211, and the other end passes through the guide wheel 63 and is connected to the side of the guide opening 621 near the aquaculture cavity 221. When not feeding, the directional cover net 62 is frustoconical and the guide opening 621 is close to the aquaculture cavity 221. The wider end of the directional cover net 62 is closer to the bait trap cavity 211, and the narrower end (i.e., the guide opening 621) is closer to the aquaculture cavity 221. When the fish-attracting monitoring unit 4 detects that there is enough bait in the bait trap cavity 211, the directional motor 64 can be activated, and the directional rope 65 pulls the guide opening 621 toward the bait trap cavity 211. In this way, the wider end of the directional cover net 62 is changed to be closer to the aquaculture cavity 221, and the narrower end (i.e., the guide opening 621) is changed to be closer to the bait trap cavity 211. At the same time, with the cooperation of the fish-attracting light 41, the aquatic animals are fed from the aquaculture cavity 221 into the bait trap cavity 211 through the directional cover net 62 of the guide tube 61.After feeding, the directional motor 64 rotates in the opposite direction, and the directional rope 65 pulls the guide opening 621 towards the rearing chamber 221. This causes the wider end of the directional cover net 62 to reappear near the bait trap chamber 211, and the narrower end (i.e., the guide opening 621) to reappear near the rearing chamber 221. Simultaneously, a sonic repellent 7, working in conjunction with the fish-attracting monitoring unit 4, is installed at the top of the bait trap cage 21. When the sonic repellent 7 is activated, the aquatic organisms return from the bait trap chamber 211 to the rearing chamber 221 through the directional cover net 62 via the guide tube 61. During this process, since the directional rope 65 is a single strand passing through the mesh of the netting of the bait trap cage 21, there is no need to worry about the directional rope 65 and the netting getting tangled when adjusting the direction. The mesh of the netting also serves as a limiting element.

[0054] Example 2: A method for self-sufficient marine aquaculture using a combined wind-fishing and feeding system, utilizing the marine aquaculture cages described in Example 1, includes the following steps:

[0055] S00: Fish attraction stage, turn on the fish attraction light 41 to attract bait creatures into the bait trap cavity 211 through the bait inlet channel 212, and use the monitoring lens 42 to observe the number of bait creatures in the bait trap cavity 211 in real time.

[0056] S10: During the feeding stage, when the number of food organisms in the bait trap cavity 211 reaches the feeding limit, the monitoring camera 42 is used to monitor and the directional motor 64 is started. The directional rope 65 is used to pull the guide port 621 from the area near the breeding cavity 221 to the area near the bait trap cavity 211. At this time, the organisms in the breeding cavity 221 enter the bait trap cavity 211 from the guide port 621 to feed.

[0057] S20: Fish driving stage. When the monitoring camera 42 detects that the cultured organisms in the bait trap chamber 211 have finished feeding, the reversing motor 64 is started in the opposite direction. The reversing rope 65 is used to pull the guide port 621 from near the bait trap chamber 211 to near the culture chamber 221. The fish attractant light 41 is turned off, and the sonic repellent 7 is started to drive the cultured organisms in the culture chamber 221 from the guide port 621 into the culture chamber 221.

[0058] S30: Turn on the fish-attracting light 41, turn off the sonic repellent 7, and enter the next stage to attract bait creatures.

[0059] Example 3: In the above examples, after the aquatic organisms finish feeding in the bait trap cavity 211, they are driven back into the aquaculture cavity 221 by the sonic drive 7 through the directional cover net 62 of the guide tube 61. However, such active driving is inefficient and time-consuming. To address this, this example proposes a marine wind-fish integrated bait self-sufficient aquaculture cage, including a cage body 2 set on the wind power support foundation 1. The cage body 2 includes a bait trap cage 21 and an aquaculture net 22 arranged vertically downwards along the coastal plane. The bait trap cage 21 includes a columnar cage composed of several cavity trusses. The outside of the columnar cage is covered with a flexible net to form the bait trap cavity 211. The top and bottom of the aquaculture net 22 are tied and fixed to the guide frame of the wind power support foundation 1 along the circumference of the wind power support foundation 1 by several connecting ropes to open the aquaculture net 22 to form the aquaculture cavity 221. The bait trap cavity 211 and the aquaculture cavity 221 are connected by the guide unit 6.

[0060] A feeding frame 5 is provided in the middle of the bait trap cavity 211. The bait trap cage 21 has several feeding channels 212 that cooperate with the feeding frame 5 along the circumference. The cross-sectional area of ​​the feeding channel 212 perpendicular to the sea level gradually decreases from the side wall of the bait trap cage 21 to the feeding frame 5. The feeding frame 5 is provided with a feeding inlet 51 that cooperates with the feeding channel 212. The bait trap cavity 211 is connected to the seawater through the feeding inlet 51. The cavity truss includes several channel frames 213. One end of the channel frame 213 is hinged to the feeding frame 5, and the other end is fixedly connected to the top frame 214. Four adjacent channel frames 213 on the side wall of the feeding frame 5 form the feeding channel 212. The feeding channel 212 is truncate. On the wind turbine support foundation 1, folding motors 9 are installed on both sides of the bait trap cage 21 to control the depth of the bait trap cage 21. The power output end of the folding motor 9 is provided with a folding rope 91. One end of the folding rope 91 is connected to the top of the bait trap cage 21. The bottom of the bait trap cage 21 is fixed to the guide frame of the wind turbine support foundation 1 through the connecting rope. In this example, after the top frame 214 is removed, the shape of the bottom of the bait trap cage 21 is maintained by the connecting rope and the guide frame of the wind turbine support foundation 1. In the vertical direction, the folding motor 9 pulls the bait trap cage 21 from the top through the folding rope 91, so that the bait trap cage 21 can remain stable to maintain the bait trap cavity 211.

[0061] In summary, unlike the embodiments described above, the bottom of the bait trap cage 21 is fixed to the guide frame of the wind power support foundation 1 via a connecting rope, thus fixing the position of the bait trap cage 21 relatively stable. It will not float excessively upwards or sink excessively. When the bait trap cage 21 is in the baiting state or the aquatic organisms are feeding, the folding motor 9 uses the folding rope 91 to pull the bait trap cage 21 taut from the top and lift it up. This reduces the pressure on the connecting rope fixing the bottom of the bait trap cage 21. Simultaneously, after the channel frame 213 is hinged to the feeding frame 5, the channel frame 213 can then... When the aquatic animals are driven into the aquaculture chamber 221 after feeding, the folding motor 9 starts, extending the folding rope 91. Under its own weight, the channel frame 213 of the bait trap cage 21 moves downwards towards the bottom of the cage, eventually settling at the position where it is fixed to the guide tube frame of the wind turbine support foundation 1 via a connecting rope. During this downward folding process, the extension speed of the folding rope 91 can be controlled by the folding motor 9, thus controlling the entire downward folding process of the bait trap cage 21. The bait trap chamber 211 is compressed as a whole to drive the fish to the feeding frame 5, and then back to the rearing chamber 221 through the guide port 621. To correspond with the top of the feeding frame 5, the top of the netting of the bait trap chamber 211 is equipped with a functional grille 8 that works in conjunction with the feeding frame 5. The functional grille 8 is equipped with a fish-attracting monitoring unit 4 and an acoustic repellent 7. In this case, because the acoustic repellent 7 corresponds to the feeding frame 5, its repelling efficiency is higher, further assisting in driving the fish back to the rearing chamber 221. When the monitoring lens 42 observes that the aquatic organisms have basically returned to the rearing chamber 221 (this... When the guide port 621 approaches the breeding chamber 221, the folding motor 9 retracts the folding rope 91, causing the top of the bait trap cage 21 to rise until the bait trap cage 21 returns to its original shape. Then, the fish-attracting light 41 is turned on to enter the next stage of the baiting process. It should be noted that, since the entire bait trap cage 21 needs to undergo a certain deformation during the folding process in this embodiment, unlike the above embodiment, a flexible net needs to be used in this example. When the net is tied to the channel frame 213, the net should initially maintain a certain slack state. This is conceivable based on the above scheme and will not be elaborated here.

[0062] In summary, in this embodiment, during the process of driving the aquatic organisms back to the aquaculture chamber 221, in addition to the cooperation of the sonic drive 7 and the guide port 621, the bait trap cage 21 is also made into a foldable state, so as to reduce the space of the bait trap cage 21 and improve the driving efficiency during the process of driving the aquatic organisms back to the aquaculture chamber 221.
