[0007] To describe in detail the technical content, achieved purpose and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0008] Please refer to Figures 1 to 5 , a floating offshore wind power integration system based on fishing and wind complementarity, including a platform 1, a wind turbine system 2 and an aquaculture system 5. The aquaculture system 5 is arranged below the platform 1; the wind turbine system 2 includes a tower barrel 21, a strut 22 and a wind sensor 23. The tower barrel 21 is arranged on the platform 1, and the strut 22 is arranged on the side of the tower barrel 21 and can rotate towards the platform 1; when the offshore wind speed monitored by the wind sensor 23 is greater than the designed maximum wind speed of the tower barrel 21, the strut 22 rotates and abuts against the platform 1.

[0009] It can be seen from the above description that the beneficial effects of the present invention are as follows: The wind power energy is provided by the wind turbine system 2, and the fishery aquaculture is carried out by the aquaculture system 5 to realize the integration of fishing and wind complementarity. The overall structure utilizes the longitudinal sea area space, has the characteristics of wide applicable sea areas, strong stability and high energy utilization rate, and is expected to be widely applied in the field of floating offshore wind power; through the cooperation of the tower barrel 21, the strut 22 and the wind sensor 23, the structural safety and economy of the wind turbine under extreme sea conditions are ensured, and the intelligent operation and maintenance of the upper wind turbine system 2 are realized.

[0010] Furthermore, the wind turbine system 2 further includes a control card slot 24. The control card slot 24 is connected to the tower barrel 21 and is electrically connected to the wind sensor 23 for opening and closing; the movable end of the strut 22 is arranged in the control card slot 24.

[0011] As described above, the support column 22 is limited and fixed by the control card slot 24 to prevent the support column 22 from unfolding by itself due to external force. When the wind speed on the sea monitored by the wind sensor 23 is greater than the maximum designed wind speed of the tower barrel 21, the control card slot 24 is opened, and then the support column 22 rotates and abuts against the platform 1.

[0012] Further, the wind turbine system 2 includes a driving member, the driving member is electrically connected to the wind sensor 23, and the driving member drives the support column 22 to rotate towards the platform 1.

[0013] As described above, through the cooperation of the driving member and the wind sensor 23, when the wind speed on the sea monitored by the wind sensor 23 is greater than the maximum designed wind speed of the tower barrel 21, the support column 22 is controlled to pop out of the control card slot 24 to provide auxiliary support.

[0014] Further, an elastic member is connected between the support column 22 and the tower barrel 21; when the wind speed on the sea monitored by the wind sensor 23 is less than the maximum designed wind speed of the tower barrel 21, the support column 22 rotates and approaches the control card slot 24 under the drive of the elastic member.

[0015] As described above, when the wind speed on the sea monitored by the wind sensor 23 is less than the maximum designed wind speed of the tower barrel 21, the driving member stops driving, and by using the resilience of the elastic member, the support column 22 rotates into the control card slot 24, realizing the automatic recovery of the support column 22.

[0016] Further, the outer side surface of the closed control card slot 24 abuts against the support column 22.

[0017] As described above, after the control card slot 24 is closed, it can serve as a support structure to provide support for the popped-out support column 22.

[0018] Further, it further includes a lifting device, the lifting device is arranged on the platform 1, and the lifting device is connected to the aquaculture system 5.

[0019] As described above, through the arrangement of the lifting device, the vertical movement adjustment of the fishing net 51 in the sea area can be realized, making full use of the sea area below the platform 1, improving the utilization rate of the vertical space in the sea area, forming an integrated system of offshore wind power and deep-sea aquaculture, and improving the resource utilization rate.

[0020] Further, the lifting device includes an anchor winch 3 and an anchor chain 31, and the anchor winch 3 is connected to the aquaculture system 5 through the anchor chain 31.

[0021] As described above, specifically, the cooperation of the anchor winch 3 and the anchor chain 31 is adopted to realize the position adjustment of the fishing net 51.

[0022] Further, it further includes a caisson 4, and the caisson 4 is arranged below the aquaculture system 5.

[0023] As can be seen from the above description, through the design of the caisson 4, the stable layout of the overall system can be achieved.

[0024] Furthermore, the caisson 4 is connected to the aquaculture system 5 through a telescopic member 41.

[0025] As can be seen from the above description, during the process of adjusting the position of the fishing net 51, the length of the telescopic member can be adjusted according to the height position of the fishing net 51, so as to meet the requirements of both the lifting and lowering of the fishing net 51 and the mooring stability of the overall structure.

[0026] Furthermore, the aquaculture system 5 includes a fishing net 51 and support rods 52. The fishing net 51 is provided with support rods 52, and the anchor chain 31 is connected to the support rods 52.

[0027] As can be seen from the above description, the fishing net 51 is fixedly arranged through the support rods 52, improving the reliability of the fishing net 51 and meeting the requirements of deep - sea aquaculture.

[0028] Please refer to Figures 1 to 5 , Embodiment 1 of the present invention is as follows: A floating - type offshore wind power integration system based on wind - fishing complementarity, comprising a platform 1, a floating board 11, a wind turbine system 2, an aquaculture system 5, a caisson 4 and a lifting device.

[0029] The floating board 11 is provided on the platform 1, the wind turbine system 2 is arranged above the platform 1, and the aquaculture system 5 is arranged below the platform 1. This design makes full use of the sea area below the floating board 11, improves the longitudinal space utilization rate of the sea area, forms an integrated system of offshore wind power and deep - sea aquaculture, and improves the resource utilization rate.

[0030] The aquaculture system 5 includes a fishing net 51 and support rods 52. The support rods 52 are solid steel pipes, and a plurality of the support rods 52 form a net frame, and the fishing net 51 is arranged on the net frame. The combined design of the support rods 52 and their solid steel pipes can improve the stability of the fishing net 51 and meet the requirements of deep - sea aquaculture.

[0031] The caisson 4 is connected to the fishing net 51 and is arranged below it. Specifically, a telescopic member is connected between the caisson 4 and the fishing net 51.

[0032] The lifting device is arranged on the platform 1, and the lifting device is connected to the fishing net 51 to adjust its longitudinal movement along the sea area. Specifically, the lifting device includes an anchor winch 3 and an anchor chain 31. The anchor winch 3 is arranged corresponding to the support rods 52, and the anchor winch 3 is connected to the support rods 52 through the anchor chain 31. By controlling the anchor chain 31 through the anchor winch 3, the longitudinal height and horizontal layout angle of the fishing net 51 are adjusted, enhancing the flexibility of the device.

[0033] When the fishing net 51 is adjusted to rise or fall, the length of the lower telescopic member can be adjusted according to the height position of the fishing net 51, so as to meet the requirements of the lifting of the fishing net 51 and the mooring stability of the overall structure at the same time.

[0034] Adopt the longitudinal connection mode of the anchor chain 31 - fishing net 51 - telescopic member to connect with the caisson 4. On the basis of providing stability for the overall structure, make full use of the longitudinal height of the fishing net 51, which can reduce the usage amount of the anchor chain 31 and the telescopic member, effectively reduce the construction cost, and increase the economic benefit while carrying out deep - sea aquaculture.

[0035] During the construction process, the caisson 4 is fixed to the seabed, and telescopic members are arranged at its four corners and connected to the upper fishing net 51, which can replace the traditional mooring system and enhance the overall stability of the structure; at the same time, it cooperates with the movable anchor chain 31 between the upper floating plate 11 and the fishing net 51, replacing the mooring cable, and forms a new mooring system.

[0036] The fan system 2 includes a horizontal - axis blade system 25, a tower barrel 21, a support column 22, a wind sensor 23, a control card slot 24 and a driving member. The horizontal - axis blade system 25 is arranged above the tower barrel 21. The tower barrel 21 is connected to the platform 1. The support column 22 is rotatably arranged on the side of the tower barrel 21. The platform 1 is located on the rotation path of the end of the support column 22. Specifically, four support columns 22 are symmetrically arranged on the side wall of the tower barrel 21.

[0037] The driving member is electrically connected to the wind sensor 23, and the driving member drives the support column 22 to rotate towards the platform 1. The control card slot 24 is arranged on the tower barrel 21, and its opening and closing operations are carried out through the monitoring and feedback of the wind speed at sea by the wind sensor 23. The support column 22 is arranged in the control card slot 24 and an elastic member is connected between the support column 22 and the tower barrel 21.

[0038] When the wind speed at sea exceeds the maximum designed wind speed of the tower barrel 21, the control card slot 24 opens, the support column 22 pops out, and the lower part of the support column 22 abuts against the floating plate 11 to provide a supporting force for the tower barrel 21. At this time, the outer side surface of the closed control card slot 24 can also abut against the support column 22 to further provide support; when the wind speed returns to the normal working condition, the support column 22 retracts, the control card slot 24 closes, and the fan support rod 52 returns to its original position, enhancing the overall structural strength of the tower barrel 21, ensuring the structural safety and economy of the fan under extreme sea conditions, and realizing the intelligent operation and maintenance of the upper fan system 2.

[0039] In summary, the floating offshore wind power integration system based on fishing-wind complementarity provided by the present invention provides wind power energy through the wind turbine system and conducts fishery aquaculture through the aquaculture system, realizing the integration of fishing-wind complementarity. The overall structure utilizes the longitudinal sea area space, featuring wide applicable sea areas, strong stability, and high energy utilization rate, and is expected to be widely applied in the field of floating offshore wind power. Through the cooperation of the tower barrel, struts, and wind sensors, the structural safety and economy of the wind turbine under extreme sea conditions are ensured, and the intelligent operation and maintenance of the upper wind turbine system are realized.
