[0026] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] As Figures 1 to 3 shown, the present invention provides an integrated structure of a wind turbine and a culture cage, including:

[0028] An offshore wind power generation device;

[0029] A reel 4, the reel 4 is installed on the rotating shaft 6 of the offshore wind power generation device, and one end of a cable 9 is fixedly wound around the reel 4;

[0030] A cage 12, the cage 12 is arranged inside the base bracket 10 of the offshore wind power generation device, and the other end of the cable 9 is connected to the cage 12;

[0031] A connecting component, the connecting component is installed on the top of the cage 12, and the cage 12 is slidably installed on the base bracket 10 through the connecting component.

[0032] When the present invention is in use, when there is no typhoon or the sea waves are small, the offshore wind power generation device generates electricity normally and the position of the cage 12 remains unchanged; when a typhoon comes or the sea waves are too large, before the offshore wind power generation device shuts down, using the residual speed before the wind turbine shuts down, the cable 9 on the reel 4 is paid out, and the cage 12 is sunk below the sea surface to realize the typhoon resistance function of the cage 12 to protect the cage 12. The present invention uses the offshore wind power generation pile as the support column 8 of the cage 12 and uses the offshore wind power generation device to realize the typhoon resistance function of the cage 12.

[0033] For a further optimized solution, the offshore wind power generation device includes a support column 8 installed on a base bracket 10. At the top of the support column 8, there is an outer cover 5 installed. Inside the outer cover 5, there are a generator 1, a first speed-changing gear 2, and a second speed-changing gear 3. The generator 1 is in transmission cooperation with the first speed-changing gear 2, the rotating shaft 6 is in transmission cooperation with the second speed-changing gear 3, and the first speed-changing gear 2 meshes with the second speed-changing gear 3; one end of the rotating shaft 6 extending out of the outer cover 5 is fixedly connected with a wind turbine blade 7; a wire reel 4 is arranged inside the outer cover 5, and a cable 9 is threaded through the inside of the support column 8.

[0034] For a further optimized solution, to facilitate the suspension of the net cage 12 so as to control the position of the net cage 12 through the cable 9, two trusses 14 are fixedly connected to the top of the net cage 12. The two trusses 14 are arranged crosswise, and the cable 9 is connected at the intersection position of the two trusses 14.

[0035] For a further optimized solution, to improve the structural strength of the net cage 12, a reinforcement frame 13 is provided at the top of the net cage 12, and the truss 14 is fixedly installed on the reinforcement frame 13.

[0036] For a further optimized solution, to ensure that the net cage 12 does not swing significantly during the hoisting process, the connection assembly includes cables fixed at the four top corners of the net cage 12. The ends of the cables are fixedly connected with sliders 11, and the sliders 11 are slidably installed on the base bracket 10.

[0037] For a further optimized solution, to ensure that the net cage 12 is not blown out of the base bracket 10 by sea breeze and sea waves, the slider 11 is of an annular structure.

[0038] For a further optimized solution, the slider 11 includes a load-bearing layer on the outside and a lubricating layer on the inside.

[0039] For a further optimized solution, an anti-corrosion coating is provided on the outside of the load-bearing layer.

[0040] For a further optimized solution, the load-bearing layer is a structural steel layer 17, the lubricating layer is a graphite layer 16, and the anti-corrosion coating is a polytetrafluoroethylene coating 15.

[0041] For a further optimized solution, to facilitate the opening and closing control of the wire reel 4, an annular chute 18 is fixedly connected to the inner wall of the outer cover 5. The annular chute 18 is coaxially arranged with the wire reel 4. A limit slider 19 is slidably connected inside the annular chute 18. A telescopic cylinder 20 is fixedly connected to the limit slider 19. A connection hole is provided on the wire reel 4, and a connection groove is provided on the rotating shaft 6. The output end of the telescopic cylinder 20 penetrates through the connection hole and is adapted to the connection groove.

[0042] When the cage 12 needs to move upward, the output end of the telescopic cylinder 20 extends and inserts into the connection groove of the rotating shaft 6. At this time, the rotating shaft 6 can drive the wire winding shaft 4 to rotate, the cable 9 on the wire winding shaft 4 winds up, and the cage 12 moves upward. After the cage 12 is lifted by a certain distance, the telescopic cylinder 20 shortens, the output end of the telescopic cylinder 20 is pulled out of the connection groove, and the transmission relationship between the wire winding shaft 4 and the rotating shaft 6 is disconnected. The rotating shaft 6 cannot drive the wire winding shaft 4 to rotate, and the self-locking positioning of the wire winding shaft 4 is realized by the friction between the limit slider 19 and the annular sliding groove 18.

[0043] When the cage 12 needs to move downward, control the telescopic cylinder 20 to continue to shorten until the output end of the telescopic cylinder 20 is pulled out of the connection hole. At this time, under the self-weight of the cage 12, the cable 9 on the wire winding shaft 4 pays out. After the cable 9 descends by a certain distance, control the telescopic cylinder 20 to extend so that the telescopic cylinder 20 abuts against the wire winding shaft 4. Under the action of inertia, the wire winding shaft 4 will not stop rotating immediately, which is convenient for the telescopic cylinder 20 to insert into the connection hole to realize the self-locking positioning of the wire winding shaft 4.

[0044] The integrated structure of the wind turbine and the aquaculture cage provided by the present invention has the following specific working process:

[0045] When a typhoon comes, the cage 12 starts typhoon protection. The wire winding shaft 4 is opened before the typhoon comes and starts to pay out the cable 9 under the self-weight of the cage 12, and the cage 12 sinks. At the same time, the slider 11 sleeved on the base bracket 10 moves downward with the cage 12 under the pull of the cable connected to the cage 12, while ensuring that the cage 12 is always located in the base bracket 10 in the sea water and is not washed out of the range of the base bracket 10 by the sea water. When the cable 9 descends by a certain distance, the wire winding shaft 4 closes and locks itself. At this time, the cable 9 stops paying out, and the cage 12 no longer sinks, lurking in the sea water to resist the damage of the typhoon. When the typhoon leaves and the wind and waves become smaller, the wire winding shaft 4 is opened, connected to the rotating shaft 6 and driven by the wind turbine blade 7 to tighten the cable 9, thereby lifting the cage 12. When the cage 12 is lifted, the cage 12 pulls the slider 11, and the slider 11 slides along the base bracket 10 to ensure that the cage 12 does not swing greatly during the lifting process. After the cage 12 is lifted by a certain distance, the connection between the wire winding shaft 4 and the rotating shaft 6 is disconnected and locked to keep the position of the cage 12.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
