Description

Technical Field

[0001] This invention relates to the field of marine aquaculture equipment technology, and more specifically, to an aquaculture device. Background Technology

[0002] Marine resources are vast and abundant. With the progress of development, humans have conducted extensive research on their development and utilization. The ocean provides excellent conditions for fish and aquatic product farming. Deep-sea cage aquaculture is an important measure to alleviate the environmental pressure on near-shore aquaculture and overcome the problems of resource constraints and space limitations. As offshore wind power develops into deep-sea areas, the integrated development of offshore wind power and aquaculture cages has become one of the ways to improve the utilization rate of marine space and reduce the development cost of offshore wind power.

[0003] Currently, existing offshore aquaculture platforms in marine environments typically combine monopile foundations with truss-type deep-sea cages. The cages are usually supported by piles, forming an overall enclosure structure. While this meets the needs of deep-sea aquaculture to some extent, its inherent limitations are becoming increasingly apparent. In particular, aquaculture activities must be halted during extreme weather conditions such as typhoons. After harvesting, the large area of ​​the cage netting is exposed to wind and waves, increasing the load on the offshore wind turbine monopile foundation and potentially damaging the netting. Summary of the Invention

[0004] The main objective of this invention is to provide an aquaculture device that can solve the problem of existing offshore aquaculture platforms where aquaculture activities need to be stopped and fish harvesting is completed under extreme weather conditions such as typhoons. After the fish are harvested, the large area of ​​the netting in the net cages will be affected by wind and waves, which not only increases the load on the offshore wind turbine monopile foundation, but also causes damage to the netting.

[0005] To achieve the above objectives, the present invention provides an aquaculture device, comprising: a monopile foundation with a connecting portion thereon; an extension and retraction mechanism including a first linkage, a second linkage, and a third linkage, wherein a first end of the first linkage is rotatably connected to the connecting portion, a second end of the first linkage is rotatably connected to the first end of the second linkage to form a connecting area, and a second end of the second linkage is rotatably connected to the first end of the third linkage; a net connecting to the monopile foundation, the first linkage, the second linkage, and the third linkage; and a drive mechanism including a first drive device and a second drive device, wherein the first drive device is connected to the connecting area, and the second drive device is connected to the second end of the third linkage.

[0006] Furthermore, the unfolding and retracting mechanism has an unfolded state and a retracted state. When the unfolding and retracting mechanism is in the retracted state, the first linkage, the second linkage, and the third linkage are stacked, and the second linkage is located between the first linkage and the third linkage.

[0007] Furthermore, when the extension and retraction mechanism is in the retracted state, the first end of the first linkage member, the first end of the second linkage member, and the first end of the third linkage member are stacked, and the second end of the first linkage member, the second end of the second linkage member, and the second end of the third linkage member are stacked.

[0008] Furthermore, when the unfolding mechanism is in the unfolded state, the unfolding mechanism is L-shaped, wherein the second linkage component is arranged in a straight line with the first linkage component, and the third linkage component is perpendicular to the second linkage component.

[0009] Furthermore, there are multiple nets and at least two deployment and retrieval mechanisms. The at least two deployment and retrieval mechanisms are arranged at intervals along the circumference of the monopile foundation. The first linkage and the second linkage are connected to form a base rod. A net is connected between two adjacent base rods and between two adjacent third linkages. The base rod and the third linkage of the same deployment and retrieval mechanism are connected to the monopile foundation together with a net. When the deployment and retrieval mechanism is in the deployed state, the nets connected between two adjacent base rods, between two adjacent third linkages, and between the deployment and retrieval mechanism and the monopile foundation together form a triangular prism aquaculture space with an opening at the top. A net is provided at the opening of the triangular prism aquaculture space.

[0010] Furthermore, there are at least two triangular prism breeding spaces, which are arranged sequentially along the circumference of the monopile foundation, and the at least two triangular prism breeding spaces are interconnected.

[0011] Furthermore, both the first and second drive devices include a winch and a connector. The winch is installed on a monopile foundation. The connector of the first drive device is connected to the connection area, and the connector of the second drive device is connected to the second end of the third linkage. The winch is used to wind up and unwind the connector.

[0012] Furthermore, the aquaculture device also includes a first limiting structure and a second limiting structure. The first limiting structure is used to keep the included angle between the first linkage and the second linkage at 180°, and the second limiting structure is used to keep the included angle between the third linkage and the second linkage at 90°.

[0013] Furthermore, the first limiting structure includes a first limiting block installed at the first end of the second linkage member. The first limiting block includes a first vertical surface, a first inclined surface, and a first arc-shaped guide surface. The second end of the first linkage member is provided with a second vertical surface, a second inclined surface, and a first connecting protrusion. The first linkage member is rotatably connected to the second linkage member through the first connecting protrusion. The first vertical surface and the first inclined surface are both located on the rotation path of the second end of the first linkage member. The outer peripheral surface of the first connecting protrusion is an arc surface adapted to the first arc-shaped guide surface. When the first linkage member rotates relative to the second linkage member, the outer peripheral surface of the first connecting protrusion fits against the first arc-shaped guide surface. When the unfolding mechanism is in the unfolded state, the first vertical surface abuts against the second vertical surface to keep the included angle between the first linkage member and the second linkage member at 180°. When the unfolding mechanism is in the retracted state, the first inclined surface abuts against the second inclined surface to keep the included angle between the first linkage member and the second linkage member at 0°.

[0014] Furthermore, the second limiting structure includes a support member. When the angle between the third linkage member and the second linkage member is 90°, one end of the support member is fixedly connected to the second linkage member, and the other end of the support member is fixedly connected to the third linkage member. The support member is supported between the second linkage member and the third linkage member.

[0015] The present invention employs a monopile foundation, an extension / retraction mechanism, and a drive mechanism. The extension / retraction mechanism comprises a first linkage, a second linkage, and a third linkage. The first end of the first linkage is rotatably connected to the connecting part, the second end of the first linkage is rotatably connected to the first end of the second linkage, and the second end of the second linkage is rotatably connected to the first end of the third linkage, enabling the extension / retraction mechanism to fold. In extreme weather conditions, the extension / retraction mechanism can be quickly retracted. Since the netting is connected to the monopile foundation, the first linkage, the second linkage, and the third linkage, the netting is also folded when the extension / retraction mechanism folds, significantly reducing the area of ​​the netting exposed to wind and waves. This reduces the risk of damage to the netting from wind and waves and also alleviates the load on the monopile foundation. Attached Figure Description

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] See also Figures 1 to 7 As shown, the present invention provides an aquaculture device, which includes: a monopile foundation 10, on which a first connecting portion 11 is provided; an extension and retraction mechanism 20, including a first linkage 21, a second linkage 22, and a third linkage 23, wherein the first end of the first linkage 21 is rotatably connected to the first connecting portion 11, the second end of the first linkage 21 is rotatably connected to the first end of the second linkage 22 to form a connecting area, and the second end of the second linkage 22 is rotatably connected to the first end of the third linkage 23; a net 30, which is connected to the monopile foundation 10, the first linkage 21, the second linkage 22, and the third linkage 23 respectively; and a drive mechanism 40, including a first drive device 41 and a second drive device 42, wherein the first drive device 41 is connected to the connecting area, and the second drive device 42 is connected to the second end of the third linkage 23.

[0034] In this embodiment, the deployment and retraction mechanism 20 is composed of a first linkage 21, a second linkage 22, and a third linkage 23. The first end of the first linkage 21 is rotatably connected to the first connecting part 11, the second end of the first linkage 21 is rotatably connected to the first end of the second linkage 22, and the second end of the second linkage 22 is rotatably connected to the first end of the third linkage 23, so that the deployment and retraction mechanism 20 can be folded. In extreme weather, the deployment and retraction mechanism 20 can be quickly retracted. Since the netting 30 is connected to the monopile foundation 10, the first linkage 21, the second linkage 22, and the third linkage 23 respectively, when the deployment and retraction mechanism 20 is folded, the netting 30 is also folded, which can greatly reduce the area of ​​the netting 30 affected by wind and waves, thereby reducing the load of wind and waves on the monopile foundation 10. The first drive device 41 is connected to the connection area. The first drive device 41 enables the first linkage 21 and the second linkage 22 to rotate relative to each other. The second drive device 42 enables the second linkage 22 and the third linkage 23 to rotate relative to each other, so as to realize the unfolding and retraction of the unfolding mechanism 20, ensuring that the net can be retrieved in time during extreme weather, reducing the stress area of ​​the net 30, and reducing the risk of damage to the net 30 when it is hit by wind and waves.

[0035] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the retractor has an extended state and a retracted state. When the retractor 20 is in the retracted state, the first linkage 21, the second linkage 22 and the third linkage 23 are stacked, and the second linkage 22 is located between the first linkage 21 and the third linkage 23.

[0036] In this embodiment, when the reaping mechanism is in the extended state, the net 30 is also in the extended state, which is used for fish farming. Before a typhoon or other extreme weather, the reaping mechanism 20 can be switched from the extended state to the retracted state by the drive mechanism 40. At this time, the first linkage 21, the second linkage 22, and the third linkage 23 are stacked together, and the net 30 is also folded along with the reaping mechanism 20, reducing the area of ​​the net 30 exposed to wind and waves, thereby reducing the risk of damage to the net 30, reducing the maintenance needs of the net 30, avoiding unnecessary replacements, reducing operating costs, and also reducing the load on the monopile foundation 10, which helps to extend the service life of the monopile foundation 10 and further save costs. When harvesting fish or performing maintenance, the reaping mechanism 20 can be switched to the retracted state for easy operation without direct manual contact with the large net 30, improving operational safety. In addition, the farming device in the retracted state is also easier to maintain and inspect, which helps to identify and repair potential problems in a timely manner.

[0037] See also Figures 1 to 6As shown, in one embodiment of the present invention, when the extension and retraction mechanism 20 is in the retracted state, the first end of the first linkage member 21, the first end of the second linkage member 22 and the first end of the third linkage member 23 are stacked, and the second end of the first linkage member 21, the second end of the second linkage member 22 and the second end of the third linkage member 23 are stacked.

[0038] In this embodiment, the stacking of the first linkage 21, the second linkage 22 and the third linkage 23 greatly reduces the space occupied by the entire unfolding mechanism 20 and the area of ​​the net 30 that is impacted by wind and waves. During typhoon season or other extreme weather conditions that require protection of aquaculture equipment, the impact of wind and waves on aquaculture equipment can be reduced, thereby reducing the load on the monopile foundation 10.

[0039] See also Figures 1 to 6 As shown, in one embodiment of the present invention, when the unfolding mechanism 20 is in the unfolded state, the unfolding mechanism 20 is L-shaped, wherein the second linkage member 22 and the first linkage member 21 are arranged in a straight line, and the third linkage member 23 is perpendicular to the second linkage member 22.

[0040] In this embodiment, the L-shaped structure can provide a relatively open planar space, which is conducive to forming a larger aquaculture area. The second linkage 22 and the first linkage 21 are arranged in a straight line to ensure the horizontal expansion of the unfolding mechanism 20. The vertical extension of the third linkage 23 further increases the three-dimensional space for aquaculture, providing a sufficient living environment for fish or other marine organisms, which is conducive to increasing aquaculture density and yield.

[0041] See also Figures 1 to 6 As shown, in one embodiment of the present invention, there are multiple nets 30 and at least two unfolding and retracting mechanisms 20. The at least two unfolding and retracting mechanisms 20 are arranged at intervals along the circumference of the monopile foundation 10. The first linkage 21 and the second linkage 22 are connected to form a bottom rod. A net 30 is connected between two adjacent bottom rods and a net 30 is connected between two adjacent third linkages 23. The bottom rod and the third linkage 23 of the same unfolding and retracting mechanism 20 are connected to the monopile foundation 10 together with a net 30. When the unfolding and retracting mechanism 20 is in the unfolded state, the nets 30 connected between two adjacent bottom rods, the nets 30 connected between two adjacent third linkages 23, and the nets 30 connected between the unfolding and retracting mechanism 20 and the monopile foundation 10 together form a triangular prism breeding space with an open top. A net 30 is provided at the opening of the triangular prism breeding space.

[0042] In this embodiment, a net 30 is connected between the bottom rods of two adjacent extension and retraction mechanisms 20, and a net 30 is connected between the third linkages 23 of two adjacent extension and retraction mechanisms 20. Each extension and retraction mechanism 20 has a first linkage 21, second linkage 22, and third linkage 23 connected to a single pile foundation 10, all sharing a net 30. For distinction, the net 30 connected between the bottom rods of two adjacent extension and retraction mechanisms 20 is named the first net 30, and the net 30 connected between the third linkages 21 and 23 of two adjacent extension and retraction mechanisms 20 is named the third linkage 23. The netting 30 between the three sections is designated as the second netting. The netting 30 connecting the first linkage 21, second linkage 22, and third linkage 23 in the monopile foundation 10 and the deployment / retraction mechanism 20 is designated as the third netting. For two adjacent deployment / retraction mechanisms 20, the two deployment / retraction mechanisms 20, together with the two third nettings, one first netting, and one second netting, form a triangular prism aquaculture space with an open top. A netting 30 is installed at the opening of this triangular prism aquaculture space to prevent fish from escaping. Through this arrangement, at least two triangular prism aquaculture spaces can be formed. Different triangular prism aquaculture spaces can cultivate different types or different growth stages of marine organisms, improving the diversity and economic benefits of aquaculture.

[0043] It should be noted that part of the prism aquaculture space is located 100 mm below the water surface, while the top of the prism aquaculture space is 100 mm above the water surface.

[0044] In one embodiment of the present invention, there are at least two triangular prism breeding spaces, which are arranged sequentially along the circumference of the monopile foundation 10, and the at least two triangular prism breeding spaces are interconnected.

[0045] In this embodiment, two adjacent triangular prism aquaculture spaces share one deployment and retraction mechanism 20. That is, the three deployment and retraction mechanisms 20 arranged circumferentially along the monopile foundation 10 and the net can jointly form two triangular prism aquaculture spaces. If two adjacent triangular prism aquaculture spaces are connected, the third net connecting the first linkage 21, the second linkage 22, and the third linkage 23 in the middle deployment and retraction mechanism 20 is not provided. Similarly, if adjacent triangular prism aquaculture spaces are connected to each other, the net 30 is not provided between the two middle deployment and retraction mechanisms 20 and the monopile foundation 10.

[0046] like Figure 1 As shown, in one embodiment of the present invention, there are five triangular prism aquaculture spaces, which are arranged sequentially along the circumference of the monopile foundation 10, thereby forming five independent aquaculture water bodies that can raise different fish species. A gap is formed between two adjacent triangular prism aquaculture spaces to allow wind turbine maintenance vessels to berth.

[0047] See also Figures 1 to 6As shown, in one embodiment of the present invention, the first driving device 41 and the second driving device 42 both include a winch 43 and a connector 44. The winch 43 is installed on the monopile foundation 10. The connector 44 of the first driving device 41 is connected to the connection area. The connector 44 of the second driving device 42 is connected to the second end of the third linkage 23. The winch 43 is used to wind up and unwind the connector 44.

[0048] In this embodiment, the connector 44 is a steel wire rope. The winch 43, by retracting and extending the connector 44, can control the positional changes of the first linkage 21, the second linkage 22, and the third linkage 23, thereby enabling the entire deployment and retraction mechanism 20 to switch between the retracted and extended states. The use of the winch 43 automates the operation of the deployment and retraction mechanism 20, eliminating the need for manual deployment or retraction, greatly improving work efficiency and reducing labor costs. In emergencies, such as typhoon warnings, the winch 43 can be quickly activated to rapidly retract the netting 30, preventing damage to it.

[0049] It should be noted that, Figure 4 The winch 43 shown in the figure is a simplified diagram. The winch 43 uses existing technology, and its specific structure will not be described in detail here.

[0050] See also Figures 1 to 6 As shown, in one embodiment of the present invention, there are multiple winches 43, and multiple second connecting parts 12 are also provided on the single pile foundation 10. The multiple second connecting parts 12 are arranged at intervals along the circumference of the single pile foundation 10. The multiple winches 43 are arranged one-to-one with the multiple second connecting parts 12, and the winches 43 are fixedly installed on their corresponding second connecting parts 12.

[0051] In one embodiment, both the first connecting part 11 and the second connecting part 12 are ear plates.

[0052] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the aquaculture device further includes a first limiting structure and a second limiting structure. The first limiting structure is used to keep the included angle between the first linkage member 21 and the second linkage member 22 at 180°, and the second limiting structure is used to keep the included angle between the third linkage member 23 and the second linkage member 22 at 90°.

[0053] In this embodiment, the function of the first limiting structure and the second limiting structure is to ensure that the angle between each linkage component remains constant when the unfolding mechanism 20 is in the unfolded state, to prevent accidental displacement or twisting between linkage components under the action of ocean currents or wind, to ensure the structural stability of the entire aquaculture device, and to prevent the net 30 from being torn or damaged due to structural deformation.

[0054] See also Figures 1 to 6 , Figures 8 to 10As shown, in one embodiment of the present invention, the first limiting structure includes a first limiting block 600 installed at the first end of the second linkage member 22. The first limiting block 600 includes a first vertical surface 601, a first inclined surface 602, and a first arc-shaped guide surface 603. The second end of the first linkage member 21 is provided with a second vertical surface 211, a second inclined surface 212, and a first connecting protrusion 213. The first linkage member 21 is rotatably connected to the second linkage member 22 through the first connecting protrusion 213. The first vertical surface 601 and the first inclined surface 602 are both located on the rotation path of the second end of the first linkage member 21. The outer peripheral surface of the connecting protrusion 213 is an arc surface adapted to the first arc-shaped guide surface 603. When the first linkage 21 rotates relative to the second linkage 22, the outer peripheral surface of the first connecting protrusion 213 fits against the first arc-shaped guide surface 603. When the unfolding mechanism is in the unfolded state, the first vertical surface 601 abuts against the second vertical surface 211 so that the included angle between the first linkage 21 and the second linkage 22 is maintained at 180°. When the unfolding mechanism is in the retracted state, the first inclined surface 602 abuts against the second inclined surface 212 so that the included angle between the first linkage 21 and the second linkage 22 is maintained at 0°.

[0055] In this embodiment, the aquaculture device further includes a rotating shaft 50, through which a first connecting protrusion 213 and a second linkage member 22 are sequentially passed, realizing a rotational connection between the first linkage member 21 and the second linkage member 22. During the rotation of the first linkage member 21 relative to the second linkage member 22, the outer peripheral surface of the first connecting protrusion 213 always remains in contact with the first arc-shaped guide surface 603. The first arc-shaped guide surface 603 provided on the first limiting block 600 can not only provide a certain support for the first connecting protrusion 213, making the rotation process more stable, but also realize rotational guidance.

[0056] When the unfolding mechanism is in the unfolded state, the first vertical surface 601 abuts against the second vertical surface 211 and forms a one-way anti-rotation fit, that is, it can prevent the first linkage 21 from continuing to rotate relative to the second linkage 22 until the included angle between them is greater than 180°. Figure 9 For example, when the unfolding mechanism is in the unfolded state, the first linkage 21 cannot continue to rotate counterclockwise relative to the second linkage 22. However, the first linkage 21 can rotate clockwise relative to the second linkage 22 until the first inclined surface 602 and the second inclined surface 212 abut against each other. When the first inclined surface 602 and the second inclined surface 212 abut against each other, the first inclined surface 602 and the second inclined surface 212 also form a one-way anti-rotation fit. Figure 8For example, at this time, the first linkage 21 cannot continue to rotate clockwise relative to the second linkage 22, but the first linkage 21 can rotate counterclockwise relative to the second linkage 22 until the first vertical surface 601 abuts against the second vertical surface 211. Through the above setting, the rotation limit between the first linkage 21 and the second linkage 22 can be achieved, so that when the unfolding mechanism is in the unfolded state, the included angle between the first linkage 21 and the second linkage 22 can be maintained at 180°, and when the unfolding mechanism is in the retracted state, the first inclined surface 602 abuts against the second inclined surface 212, so that the included angle between the first linkage 21 and the second linkage 22 is maintained at 0°.

[0057] See also Figures 1 to 6 , Figures 11 to 13 As shown, in one embodiment of the present invention, the second limiting structure includes a second limiting block 700 installed at the second end of the second linkage member 22. The second limiting block 700 includes a third vertical surface 701, a fourth vertical surface 702, and a second arc-shaped guide surface 703. The first end of the third linkage member 23 is provided with a fifth vertical surface 231, a sixth vertical surface 232, and a second connecting protrusion 233. The third linkage member 23 is rotatably connected to the second linkage member 22 through the second connecting protrusion 233. The third vertical surface 701 and the fourth vertical surface 702 are both located on the rotation path of the first end of the third linkage member 23. The outer peripheral surface of the second connecting protrusion 233 is an arc surface adapted to the second arc-shaped guide surface 703. When the third linkage 23 rotates relative to the second linkage 22, the outer peripheral surface of the second connecting protrusion 233 fits against the second arc-shaped guide surface 703. When the unfolding mechanism is in the unfolded state, the fourth vertical surface 702 abuts against the fifth vertical surface 231 so that the included angle between the second linkage 22 and the third linkage 23 is maintained at 90°. When the unfolding mechanism is in the retracted state, the third vertical surface 701 abuts against the sixth vertical surface 232 so that the included angle between the third linkage 23 and the second linkage 22 is maintained at 0°.

[0058] In this embodiment, the aquaculture device further includes a rotating shaft 50, through which a second connecting protrusion 233 and a second linkage member 22 are sequentially passed to achieve a rotational connection between the third linkage member 23 and the second linkage member 22. During the rotation of the third linkage member 23 relative to the second linkage member 22, the outer peripheral surface of the second connecting protrusion 233 always remains in contact with the second arc-shaped guide surface 703. The second arc-shaped guide surface 703 provided on the second limiting block 700 can not only provide a certain support for the second connecting protrusion 233, making the rotation process more stable, but also guide the rotation.

[0059] When the unfolding mechanism is in the unfolded state, the fourth vertical surface 702 and the fifth vertical surface 231 abut against each other and form a one-way anti-rotation fit, that is, it can prevent the third linkage 23 from continuing to rotate relative to the second linkage 22 until the included angle between the two is greater than 90°, so as to prevent the third linkage 23 from continuing to rotate relative to the second linkage 22 until the included angle between the two is greater than 90°. Figure 11 For example, when the unfolding mechanism is in the unfolded state, the third linkage 23 cannot continue to rotate clockwise relative to the second linkage 22. However, the third linkage 23 can rotate counterclockwise relative to the second linkage 22 until the third vertical surface 701 abuts against the sixth vertical surface 232. When the third vertical surface 701 abuts against the sixth vertical surface 232, the third vertical surface 701 and the sixth vertical surface 232 also form a one-way anti-rotation fit. Figure 13 For example, at this time, the third linkage 23 cannot continue to rotate clockwise relative to the second linkage 22, but the third linkage 23 can rotate counterclockwise relative to the second linkage 22 until the fourth vertical surface 702 abuts against the fifth vertical surface 231. Through the above setting, the rotation limit between the third linkage 23 and the second linkage 22 can be realized, so that when the unfolding mechanism is in the unfolded state, the included angle between the third linkage 23 and the second linkage 22 can be maintained at 90°, and when the unfolding mechanism is in the retracted state, the included angle between the third linkage 23 and the second linkage 22 can be maintained at 0°.

[0060] In one embodiment, the first vertical surface 601, the second vertical surface 211, the third vertical surface 701, the fourth vertical surface 702, the fifth vertical surface 231, and the sixth vertical surface 232 are all planes parallel to the vertical surfaces.

[0061] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the first limiting structure includes a first protrusion 200, a second protrusion 300, and a locking member 400. The first protrusion 200 is disposed on the first linkage member 21, and the second protrusion 300 is disposed on the second linkage member 22. The first protrusion 200 is provided with a first through hole, and the second protrusion 300 is provided with a second through hole. When the angle between the first linkage member 21 and the second linkage member 22 is 180°, the first protrusion 200 and the second protrusion 300 are respectively located on opposite sides of the connecting area, and the first through hole and the second through hole correspond to each other. The first end of the locking member 400 passes through the first through hole, and the second end of the locking member 400 passes through the second through hole. The protruding end of the locking member 400 is threadedly connected to a nut 500.

[0062] In this embodiment, the first protrusion 200 is detachably connected to the first linkage 21 by bolts, and the second protrusion 300 is detachably connected to the second linkage 22 by bolts. When the unfolding mechanism 20 is in the unfolded state, the first protrusion 200 can be manually bolted to the first linkage 21, and the second protrusion 300 can be manually bolted to the second linkage 22. Then, the locking member 400 passes through the first through hole and the second through hole in sequence. At this time, the first end of the locking member 400 protrudes from the first through hole, and the second end of the locking member 400 protrudes from the second through hole. The locking member 400 has a threaded section at the portion protruding from the first through hole and a threaded section at the portion protruding from the second through hole. Both threaded sections are threadedly connected to a nut. The nut at the first end of the locking member forms a stop engagement with the end face of the first protrusion 200 along the length of the first linkage 21. The nut at the second end of the locking member forms a stop engagement with the end face of the second protrusion 300 along the length of the second linkage 22. The engagement of the two nuts 500 prevents the locking member 400 from disengaging from the first protrusion 200 and the second protrusion 300. This design ensures that the included angle between the first linkage 21 and the second linkage 22 remains at 180°. When the retractable mechanism 20 needs to be in the retracted state, the first protrusion 200, the second protrusion 300, and the locking member 400 can be manually removed.

[0063] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the second limiting structure includes a support member 80. When the angle between the third linkage member 23 and the second linkage member 22 is 90°, one end of the support member 80 is fixedly connected to the second linkage member 22, and the other end of the support member 80 is fixedly connected to the third linkage member 23. The support member 80 is supported between the second linkage member 22 and the third linkage member 23.

[0064] The above settings ensure that the angle between the third linkage 23 and the second linkage 22 is maintained at 90°.

[0065] It should be noted that, Figure 1 Only one support member 80 is shown. The support member 80 is a rod structure. One end of the support member 80 is detachably connected to the second linkage member 22 by bolts, and the other end of the support member 80 is detachably connected to the third linkage member 23 by bolts. When the unfolding mechanism 20 is in the unfolded state, the two ends of the support member 80 can be manually bolted to the second linkage member 22 and the third linkage member 23 respectively. When it is necessary to make the unfolding mechanism 20 in the retracted state, the support member 80 can be manually removed.

[0066] See also Figures 1 to 6As shown, in one embodiment of the present invention, the aquaculture device further includes a wind turbine tower 90 and a plurality of blades 70 rotatably disposed on the wind turbine tower 90, the bottom of the wind turbine tower 90 being connected to a monopile foundation 10.

[0067] In this embodiment, the sea space below the wind turbine tower 90 is effectively utilized to house aquaculture equipment. This not only improves the utilization rate of offshore space but also achieves dual economic benefits from wind power generation and marine aquaculture, reducing the waste of marine resources. The integration of the aquaculture equipment with the wind turbine tower 90 means that resources such as electricity, communication, and personnel management can be shared, for example, using wind power to supply electricity to the aquaculture equipment.

[0068] In one embodiment of the present invention, the aquaculture device further includes a plurality of rotating shafts 50, the first end of the first linkage member 21 is rotatably connected to the connecting part through the rotating shaft 50, the second end of the first linkage member is rotatably connected to the first end of the second linkage member 22 through the rotating shaft 50, and the second end of the second linkage member 22 is rotatably connected to the first end of the third linkage member 23 through the rotating shaft 50.

[0069] During piling, to facilitate construction, the aquaculture equipment was positioned... Figure 6 In the current state, with the single pile foundation 10 completed, to enable the aquaculture function, the connecting piece 44 can be released via a winch, allowing the deployment and retrieval mechanism to move from... Figure 5 The state unfolds to Figure 1 The aquaculture device is in its unfolded state (C) and retracted state (B). At this point, the top of the device is slightly above sea level. When harvesting fish, the operation can be reversed; the winch tightens the connector 44, and the aquaculture device is retracted from its unfolded state (C) to its retracted state (B). The device is then folded up for easier fish harvesting. Simultaneously, during typhoon season, aquaculture activities cease, and the device can be further retracted to its folded state (A), thereby reducing the stress area of ​​the netting under wind and waves and lessening the load on the monopile foundation. When folded, the connecting rod is pressed tightly against the monopile foundation, further reducing the stress area of ​​the aquaculture device.

[0070] In one embodiment of the present invention, the connection between the mesh 30 and the monopile foundation 10, the first linkage 21, the second linkage 22, and the third linkage 23 can be achieved by the following method: multiple hooks are provided on the mesh 30, and multiple hanging rings are provided on the monopile foundation 10, the first linkage 21, the second linkage 22, and the third linkage 23. The multiple hooks correspond one-to-one with the multiple hanging rings, and the hanging rings are hung on their respective hanging rings. Alternatively, the connection between the mesh 30 and the monopile foundation 10, the first linkage 21, the second linkage 22, and the third linkage 23 can be achieved by adhesive bonding.

[0071] In one embodiment of the present invention, the connection between the netting 30 and the monopile foundation 10, the first linkage 21, the second linkage 22 and the third linkage 23 can also be achieved by the following method: binding rods are provided on the monopile foundation 10, the first linkage 21, the second linkage 22 and the third linkage 23, and the netting is bound to the binding rods.

[0072] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: A monopile foundation, a retraction mechanism, and a drive mechanism are provided. The retraction mechanism consists of a first linkage, a second linkage, and a third linkage. The first end of the first linkage is rotatably connected to the connecting part, the second end of the first linkage is rotatably connected to the first end of the second linkage, and the second end of the second linkage is rotatably connected to the first end of the third linkage, enabling the retraction mechanism to fold. In extreme weather, the retraction mechanism can be quickly retracted. Since the netting is connected to the monopile foundation, the first linkage, the second linkage, and the third linkage respectively, the netting is also folded when the retraction mechanism is folded, which can significantly reduce the area of ​​the netting exposed to wind and waves. This reduces the risk of damage to the netting when exposed to wind and waves and also reduces the load of wind and waves on the monopile foundation.
