Technical Field

[0001] The invention belongs to the technical field of deep-sea aquaculture, and in particular relates to an economical wind-fishing fusion device. Background Art

[0002] In the context of increasingly tight marine resources, traditional offshore aquaculture and offshore wind power occupy large areas of sea respectively, resulting in low efficiency in the utilization of marine resources. By combining aquaculture cages with monopile foundation offshore wind power, the infrastructure of offshore wind farms can be fully utilized, and the original single-function sea area can be transformed into a multi-functional area, which not only meets the needs of wind power generation, but also provides aquaculture space, thereby improving the utilization efficiency of marine resources.

[0003] However, typhoons are common natural disasters, and the strong winds and huge waves they bring will pose a severe test to wind-fish fusion devices. For aquaculture cages, existing wind-fish fusion devices are often unable to withstand the impact of typhoons, causing the cages to move, deform, or even disintegrate, which not only directly threatens the safety of aquaculture organisms, but may also pose a threat to wind turbine tower foundations and underwater cables, causing greater economic losses and safety risks.

DETAILED DESCRIPTION

[0015] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0016] like Figure 1 As shown, the present invention discloses an economical wind-fishing fusion device, comprising: a wind power monopile foundation 4, a breeding cage 5, a retractable module 9 and a tension module 6; The wind turbine monopile foundation 4 is arranged in a preset offshore area; the wind turbine monopile foundation 4 in this embodiment adopts a reinforced concrete structure. The top of the wind turbine monopile foundation 4 is provided with a wind turbine blade 1, a wind turbine nacelle 2 and a wind turbine tower 3 in sequence.

[0017] like Figure 3 As shown, the aquaculture cage 5 is mounted on the wind power monopile foundation 4; preferably, the aquaculture cage 5 includes a first half ring 51 and a second half ring 52; The first butt ends of the two half rings are movably connected, and the second butt ends 54 are detachably connected. The movably connected is a hinge or a pin connection, which is convenient for opening and closing the aquaculture cage 5; the second butt ends 54 are detachably connected by fasteners such as bolts and nuts to ensure the stability of the aquaculture cage 5 when closed. The aquaculture cage 5 is provided with a breeding rack and a feeding device for breeding fish and other aquatic products.

[0018] In one embodiment, the present invention configures the breeding cage 5 as a circular frame and a plurality of steel cables 8 respectively connected to the upper and lower surfaces of the circular frame. One ends of the plurality of steel cables 8 on the upper and lower surfaces of the circular frame are connected to the circular frame, and the other ends converge at one point and are connected to the first connecting subunit 10, forming a cone as a whole. The circular frame is composed of two semi-annular structures, and the first butt joint ends of the two semi-annular structures are movable connections, and the second butt joint ends 54 are detachable connections, which not only facilitates the installation and disassembly of the breeding cage 5, but also facilitates regular cleaning, inspection and maintenance.

[0019] The retractable module 9 is arranged on the wind power monopile foundation 4 and connected to the aquaculture cage 5, and is used to adjust the depth of the aquaculture cage 5 on the seabed; Preferably, the retractable module 9 includes a lifting unit and a lowering unit both arranged on the wind power monopile foundation 4; The breeding cage 5 is connected between the lifting unit and the lowering unit; The raising unit and the lowering unit are used to drive the breeding cage 5 to rise and fall along the wind power monopile foundation 4 respectively.

[0020] Preferably, the lifting unit comprises a power subunit and a first connecting subunit 10; The power subunit is arranged on the wind power monopile foundation 4, and is located on the side of the breeding cage 5 facing the sky; One end of the first connecting subunit 10 is connected to the breeding cage 5, and the other end is connected to the power subunit.

[0021] like Figure 2 As shown, in one embodiment, the power subunit is any one of a winch, a worm gear type retracting and releasing mechanism, a hydraulic type retracting and releasing mechanism, an electric screw type retracting and releasing mechanism or a chain sprocket type retracting and releasing mechanism, the first connecting subunit 10 is a lifting cable (or wire rope), the lifting cable is connected to the aquaculture net box 5, and the power subunit adjusts the height of the aquaculture net box 5 by retracting and releasing the lifting cable (or wire rope). This embodiment realizes the lifting function of the aquaculture net box 5 through a simple combination of a winch and a counterweight unit 7. This design is relatively simple and has fewer components, so it is more convenient to maintain and operate. The design of the counterweight helps to maintain the stability of the aquaculture net box 5 during the lifting process and reduce the risk of shaking and tilting. At the same time, the control of the winch is relatively easy, and the precise control of the lifting speed of the aquaculture net box 5 can be achieved.

[0022] Preferably, the descending unit comprises a counterweight subunit 7; The counterweight subunit 7 is arranged on the wind power monopile foundation 4 and is located on the side of the aquaculture cage 5 facing the seabed; The counterweight subunit 7 is connected to the aquaculture cage 5 and is used to drive the aquaculture cage 5 to sink by its own gravity, thereby adjusting the depth of the aquaculture cage 5.

[0023] The counterweight subunit 7 is sleeved on the wind power monopile foundation 4. In this embodiment, the counterweight subunit 7 is made of steel, has a cylindrical shape, and has a diameter slightly larger than the diameter of the wind power monopile foundation 4, so as to be sleeved on the wind power monopile foundation 4. The weight of the counterweight subunit 7 is set according to actual needs, and usually needs to ensure that the aquaculture cage 5 can still be stably driven to sink under the action of external forces such as wind and waves.

[0024] The present invention sets the ascending unit and the descending unit of the retracting module 9 separately, which can be operated and controlled independently, so that the lifting process of the breeding cage 5 is more flexible and accurate, meeting the depth adjustment requirements under different breeding needs, and when a failure occurs or maintenance is required, one of the units can be repaired or replaced separately, reducing maintenance costs and time.

[0025] The tension module 6 is sleeved on the retractable module 9 and is used to clamp the retractable module 9 after the depth adjustment of the aquaculture cage 5 is completed, so as to fix the depth of the aquaculture cage 5 .

[0026] like Figure 4 As shown, the tension module 6 is a detachable connection between the first semi-annular structure 61 and the second semi-annular structure 62. The material is selected from high-strength stainless steel or alloy materials to ensure its corrosion resistance and durability. The inner diameter of the semi-annular structure is slightly larger than the diameter of the retractable module 9, so that it can be easily mounted on the retractable module 9. At the same time, the two ends of the semi-annular structure are designed with a third docking end 63, and the third docking end 63 is provided with a bolt hole or a buckle, so as to achieve the close connection and disassembly of the two semi-annular structures.

[0027] The present invention is provided with a retractable module 9 and a tension module 6. Before a typhoon comes, the operator can quickly adjust the depth of the aquaculture cage 5 through the retractable module 9 and sink it to a relatively safe sea depth to avoid direct impact of huge waves and strong winds brought by the typhoon on the aquaculture cage 5 and fish; the design of the tension module 6 enables the aquaculture cage 5 to be firmly fixed in the specified position after the depth is adjusted, effectively preventing the aquaculture cage 5 from shaking or drifting due to the ocean current and wind caused by the typhoon, thereby ensuring the safety of the aquaculture facilities.

[0028] In one embodiment, the use process of the device of the present invention is as follows: Normal state: Initially, the tension module 6 is in a relaxed state, and the retracting and releasing module 9 controls the length of the lifting cable to adjust the position of the breeding cage 5; when it reaches a suitable position, the retracting and releasing module 9 stops working, and the tension module 6 is manually adjusted to hold the wind power monopile foundation 4 tightly, and the system enters a normal operating state. The present invention has a simple structure, a small amount of steel, is easy to install, and has good economic performance.

[0029] Typhoon avoidance state: In order to reduce the load on the entire system and protect the cultured marine organisms, the tension module 6 is opened, the retracting and releasing module 9 controls the extension of the lifting rope, and the culture cage 5 dives to a certain depth underwater under the action of the counterweight subunit 7. The retracting and releasing module 9 stops working, the tension module 6 holds the wind turbine monopile foundation 4 tightly, and the entire system avoids the typhoon underwater.

[0030] The above are only a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with the profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
